Description

Overload protection device

Description: The invention relates to a load securing device. Furthermore, the invention relates to a lifting slide with load securing device.

Under lifting is understood to mean a device for attachment to a mast, wherein such a mast, for example, the mast of a material handling vehicle and wherein on the lifting a load receiving means, such as a lifting fork, can be fastened. These are lifting forks

Usually used in pairs, for example, to safely lift pallets on which a load is located. Lifting carriages are known in the art. For example, German laid-open specification DE 10 2012 217 996 A1 discloses a lifting carriage for attachment to a mast with which a given mast can be given more stroke, it being ensured that the forks are always moved synchronously and therefore always on a in the

Substantially the same height. From the prior art it is also known to attach the lifting forks horizontally in the same direction or relative to each other movable on a lifting. The lifting forks can be individually positioned by manually hanging on different positions of the lifting. For example, from the German patent application DE 10 201 1 002 433 A1 discloses a lifting is known in which at least two horizontally movable load-bearing elements are relatively movable by drive elements, so that the horizontal positions of the load-bearing elements not manually by hanging, but remotely, for example, from the cab one

Fork lift truck, can be adjusted, the operator of the

Industrial truck for adjusting the horizontal positions of the

Lifting elements must not leave the cab of the truck. Now with a fortified on such a lifting

Load receiving element picked up and lifted a load, so there is the Risk of the load falling off the load-bearing element. In this case, the load on three sides of the load-receiving element fall down, namely in the lifting carriage opposite direction, hereinafter referred to as the front direction, as well as in the two horizontal, substantially perpendicular to

Front-facing directions, hereinafter referred to as side directions. If the load-bearing element is a lifting fork, the provision of a sufficient length of the lifting fork can cause it to fall down

Front direction can be safely prevented. Many industrial trucks have one

Tilting device, with the help of which the load can be tilted backwards by a small angle, thus further reducing the risk of tilting of the load in the frontal direction. Since lifting forks are usually used in pairs, by choosing the horizontal position of the two forks to each other, namely in each case as far as possible on the outer edges of the load to be lifted, at a load width adapted to the load height or height of the center of gravity of the load side down the load also safe be prevented. The same applies to the transport of the lifted load, for example with a

Industrial truck, especially when cornering and / or driving on a crooked or uneven plane transverse to the front direction.

In certain cases, however, the load to be picked is very narrow compared to the height, for example, so narrow that the two forks must be positioned so that they are very close together and may even touch to fit under the load. Such loads are usually provided with their own spacers to the ground, so that the Hubgabelzinken can be pushed under the load. In some cases these are

But spacers are so small that only relatively thin forks fit under the load. The spacers are minimized to the

Packing density in shelving systems or during transport, for example in

To increase trucks or containers in which such loads can be stored vertically one above the other. Are such loads additionally relatively long and heavy, it comes when lifting the load to strong deflections of

Lifting forks and during transport, in particular over uneven floors to Federbeziehungsweise rocking movements of Hubgabeln. This is associated with an increased risk of dropping the load from the lift forks, the lateral Stability of the load on the lift forks is severely limited by the minimum width of the load support by the lift forks.

On the other hand, it is a further requirement to minimize shelf spacing in load racks in which loads are stored, in order to save hall height or install as many vertically stacked shelves in a given hall height. It follows that masts and

Load safety devices should build as little as possible in the vertical direction. In addition, for example, attached to forklift trucks

Masts of the cross section through which the driver of the industrial truck his track and the load to be picked up or transported

watched, be as big as possible.

From the German patent application DE 10 040 249 A1 is a

Load securing device is known which ensures a load deposited on a load-receiving element during transport against falling down. A

Load securing device has for this purpose a holding or pressure element, which is connected to the load receiving elements raised and lowered, at intervals over the entire, formed by the transport units loading width of the vehicle distributed two or more holding or Andruckorgane

can be provided. From the European patent application EP 0 467 210 A1 is also a

Load securing device known. The load securing device has a load-holding plate which can be displaced on a guide rail parallel to the mast and / or lateral support plates which are laterally displaceably mounted on further guide rails. In the known load securing devices, however, the flexibility of

Hubschlittens limited by the load securing devices themselves. In the prior art, to solve this problem, examples are known in which the holding element can be manually or hydraulically folded away.

However, in these systems, the cross-section through which an operator of the load securing device his track and the male

or to monitor transported load, significantly limited. In addition, this greatly limits the possible vertical height of the load and the weight of a lifting slide with mounted load securing device is greatly increased, which reduces the maximum load can be absorbed by the lifting carriage accordingly.

The object of the invention is to provide a load-securing device, with which even in narrow and / or long load to be absorbed by a load receiving element a fall of the load from the load receiving element is reliably prevented, in spite of the proposed load securing device neither the cross section through which an operator of the load securing device observe its travel path and the load to be picked up or transported, substantially restricted, nor should the possible vertical height of the load be excessively restricted by the load securing device. In addition, the load securing device should be designed as easily as possible.

In addition, the load securing device should have the largest possible vertical adjustment range or opening area to the load-receiving element, so that both high and low loads can be stabilized, safely and quickly absorbed and transported.

According to the invention, this object is achieved by a load securing device having the features of independent claim 1. A further object of the invention is to provide a lifting carriage with a load-receiving element, with which a drop of the load is reliably prevented from the load-receiving element, even with narrow and / or long load to be absorbed, wherein neither the cross section through which an operator of the lifting carriage can observe its travel path and the load to be picked up or transported is substantially restricted, nor is the excessively limited possible vertical height of the load. In addition, the lifting should be as easy as possible.

This further object is achieved by a lifting carriage according to claim 15.

A load securing device according to the invention is characterized in that it comprises at least one mast and a holding element, a supporting element and a

Guide rail, wherein the guide rail at its lower end, ie the lying in the opposite x-direction, the ground-facing end, a bent by 90 ° relative to the x-axis curved path, the

Load securing device on which at least one mast in the x-direction is arranged vertically displaceable, the guide rail is extended substantially parallel to the at least one mast and the support member with the

Guide rail is engaged, wherein the support member is supported by the guide rail and wherein the holding member is pivotally mounted about a pivot point, wherein the holding member by pivoting in a in the

Essentially horizontal position is activated, wherein the pivoting of the

Retaining element in the vertical direction (x) is prevented by the support member.

The load securing device can be activated by pivoting the retaining element in a substantially horizontal position. In the deactivated state, the retaining element is folded away in a substantially vertical position, so that it does not restrict the inclusion of protruding loads that require no load protection, and maximizes the flexibility of the applications of the lifting in this position. By the support of the retaining element on the guide rail, if the support element is in engagement with the guide rail, is a

Dodge the retaining element in a simple manner mechanically prevented, so that no force application means such as hydraulic cylinders are required to apply the holding force on the holding element. In addition, eliminates the need for a hydraulic cylinder hydraulic control and it must be laid no hydraulic hoses. These hoses would have to be carried along the entire vertical adjustment of the holding device and would take up space and increase the cost of production. The

Load securing device is so far in the vertical direction at the at least one

To move the mast that the support element is no longer engaged with the mast

Guide rail is. This is possible, for example, by choosing a shorter length of the guide rail in comparison to the at least one mast. If the support element is no longer in engagement with the guide rail, the support element can be pivoted about a pivot point in a substantially vertical position and thereby deactivated. The fact that no force application means are required for applying the holding force, the load securing device is small and compact, which is positive in terms of cross-section, the

Observation possibility of the guideway and the male or female respectively load to be transported by which an operator of the load-securing device as well as the dead weight of the device affects. This will make the recordable

The maximum weight of a load is only slightly limited and the energy consumption for lifting a load is minimized. In addition, the

Load securing device as large a vertical adjustment or opening area to the load-bearing elements, which stabilized both high and low loads can be safely and quickly absorbed and transported.

By Verschwenkmöglichkeit of the retaining element is the

Load safety device can be activated and deactivated. In applications in which a load securing is not required or even undesirable, thus the load securing device can be easily folded away in a substantially vertical position. For this purpose, the load securing device can be moved vertically in the direction of the load-receiving element, wherein the load-receiving device is pivotable as soon as the support element is no longer in engagement with the

Guide rail is located so that it is no longer supported.

The load securing device can for example be attached to a known lifting carriage, which in turn is fastened, for example, to an industrial truck. The lifting carriage can in turn be a device for

Hubvergrößerung exhibit. In this case, it is advantageous if the

Load securing device is attached to the Hubvergrößerungsvorrichtung.

In an advantageous embodiment, the holding element is pivotable in the positive x-direction. For example, the at least one mast projects beyond the guide rail in the positive x direction. To deactivate, the load securing device is driven so far on the at least one mast up in the positive x-direction that the support element is no longer with the

Guide rail is engaged. The holding element is thereby pivoted to deactivate about the pivot point in the opposite x-direction and has in the deactivated state down in the opposite x-direction. In an alternative embodiment, the holding element is pivotable in the negative x-direction. For example, the at least one mast projects beyond the guide rail in the negative x direction. To disable it in this Embodiment, the load securing device as far down the at least one mast down in the opposite x-direction that the support element is no longer engaged with the guide rail in engagement. The holding element is thereby pivoted to deactivate about the pivot point in the x direction and has in the deactivated state upwards in the x direction. As a result, the lifting carriage with deactivated load securing element has a lower overall height than in the previously described reverse case.

In a preferred embodiment, the retaining element in a substantially vertical position in the positive y-direction is not extended beyond the maximum extent of the at least one mast in the positive y-direction. Here, the positive y-direction is the direction in which the load-bearing member is extended to load-bearing, i. in other words the advance direction of a

Industrial truck. The substantially vertical position of the retaining element corresponds to the deactivated state of the load securing device. Because the holding element in the deactivated state does not protrude beyond the at least one mast in the forward direction of the industrial truck, the builds

Load securing device in this direction particularly compact, so that the usable depth of the load-bearing element for load-bearing is minimized only minimally. It is particularly advantageous if the load securing device is attached to a lifting carriage such that the at least one mast does not project beyond the lifting carriage in the positive y-direction. In this case, the usable depth of the load-bearing member for load bearing is not limited.

It has also proven to be advantageous if the load securing device further comprises a yoke, wherein the holding element is pivotable in relation to the yoke in the vertical direction. The yoke forms when using two im

Substantially parallel masts the connecting bridge to the vertical

Holding element guides and increases the stability of the load securing device.

Furthermore, it has proved to be advantageous if the yoke and the holding element in the x-direction or in the opposite x-direction are vertically movable in the same direction, with their vertical distance is constant. The holding force of the

Load acts against the retaining element, provides a bending moment that must be intercepted. But this bending moment but also on the support element on the Guide rail is transmitted, the yoke itself does not absorb bending moment, but only a reaction force and can thus be performed easily.

In an advantageous embodiment, the load securing device further comprises a force accumulator, wherein the energy accumulator is tensioned when the

Retaining element is located in a substantially horizontal position. The force accumulator exerts a torque on the retaining element about the axis of rotation in the

Pivoting direction, the deactivation of the load securing device

equivalent. As long as the support element and thus the load securing device is located in the region in which the support element is in engagement with the guide rail, the supporting element supported on the guide rail counteracts this torque. But if the load securing device moves vertically as far in the direction of the load receiving member, that the support element is out of engagement with the guide rail, the support member is no longer supported by the guide rail and the holding member pivoted by the force applied by the power storage torque about its axis of rotation in the vertical direction so that the load securing device is deactivated. It is particularly advantageous that the pivoting is done solely by the vertical movement of the load securing device, without the need for an additional activator, such as an additional hydraulic or pneumatic cylinder. As a result, the load securing device builds particularly small, which is advantageous to the cross section through which an operator of the lifting can observe his track and the load to be picked or transported and affects the possible vertical height of the load. In addition, the weight of the lifting is further minimized. In addition, eliminates the need for an activator control and there are no media hoses, such as hydraulic or pneumatic hoses, or electric cables are laid. These hoses or cables would have to be carried along the entire vertical adjustment range of the holding device and would take up space and increase the manufacturing costs. The energy accumulator is connected on one side with the yoke and with the other side with the pivotable holding element. The preferred gas spring can be mounted both horizontally and vertically. In an advantageous embodiment, the energy accumulator is a compression spring.

For example, the energy accumulator may be a gas spring. Alternatively, the energy accumulator may also be a tension spring, for example a gas tension spring. Gas pressure and gas tension springs are known in the art. They are characterized by a large compared to their size power delivery, low weight and

Maintenance-free. This further reduces the cross-section through which an operator of the lifting carriage can observe his travel path and the load to be picked up or transported and optimizes the possible vertical height of the load. In addition, the weight of the load securing device is further optimized. A great advantage of this preferred embodiment is that when at

Lifting the load carriage, the holding element to an overlying

Shelf element abut it, it can move down against the spring force and thus the probability of damage on the

Retaining element and / or the shelf is significantly minimized. It has further proven to be advantageous if the support element has a wear element, with which the support element is supported on the guide rail. In the vertical

Moving the load securing device rubs the support element on the

Guide rail. By the wear element while the wear is concentrated on this element, with the wear element can be easily replaced. Thus, the maintenance of the load securing device is minimized. The wear element may for example be designed as a roller or roller bearings. Alternatively, the provision of a sliding bar as a wear element is possible.

In an advantageous embodiment, the guide rail is operatively connected to the at least one mast. In particular, the at least one mast can also be designed as a guide rail itself.

It has proved to be advantageous if the lifting a

Height adjustment device for the load securing device, by means of which the load securing device along the guide rail in the vertical direction (x) is adjustable. The height adjustment device is integrated in a particularly advantageous embodiment in the at least one mast. By integrating the

Height adjustment device in the at least one mast is the

Height adjustment device largely protected against mechanical damage and requires no additional space. For example, the Hohenverstellvornchtung a spindle, such as a ball screw, or a hydraulic cylinder be. The Hohenverstellvornchtung in the area just before the end position simultaneously represents the actuator with which the

Retaining element pivots and thus the load securing device is activated or deactivated.

The height adjustment device has at least one guide profile. Preferably, the height adjustment on two guide profiles, which are rear, that is, in the direction of a recorded load groundbreaking, attached to the lifting load receiving elements or arranged laterally therefrom. The at least one height adjustment device can be mounted outside the guide profile or integrated in the guide profile, whereby it is advantageously protected. With a sufficiently long guide, the

Height adjustment be integrated only in a guide profile, wherein in the other guide profile only one profile is performed.

In a further advantageous embodiment, the holding element has a maximum extent D from the axis of rotation to that of the axis of rotation

opposite direction, wherein the length H _{F of} the guide rail corresponds to at least the extension D of the holding element. With such a size relation, the retaining element can be folded completely completely into a substantially vertical position, so that in the deactivated state it has no extension beyond the at least one mast in the positive y-direction and thus does not restrict the maximum usable depth of the load-bearing element.

Further advantages, features and expedient developments of the invention will become apparent from the dependent claims and the following description of preferred embodiments with reference to the drawings.

Fig. 1 shows a load securing device 100 according to the invention on a

Lifting slide 150 in a three-dimensional view from the front with activated holding element 1 10. On the lifting slide 150 are two lifting forks 160 as

Load receiving element attached. The load securing device has two masts 151 of length H _M , to which a holding element 1 10 via a yoke 1 1 1 is attached. The holding element 1 10 is in activated, that is located forward in the positive y-direction in the direction of the lifting forks 160 pivoted position. At the yoke 1 1 1, the frame-shaped support member 1 10 is pivotally mounted about a rotation axis 1 12. The yoke 1 1 1 is connected via height adjustment 1 15, which are mounted in the mast profiles, vertically movable connected to the masts 151, wherein at least one height adjustment device 1 15 is designed as a hydraulic cylinder. Furthermore, in the illustration, a gas spring 140 as

Recognizing force accumulator, the gas spring 140 a force on the

Retaining element 1 10 exerts, which generates a torque about the axis of rotation 1 12. The holding element 1 10 has an extension D in the direction of the lifting forks 160. Furthermore, two guide rails 130 of length H _{F are} attached to the masts 151, which end in the opposite x-direction, each with a curved path 131. The holding element 1 10 is in its highest position. In this position, a load can be picked up with the lift forks 160. Is the load taken up, can the support member 1 10 are lowered in the vertical direction against the x-direction of the load to clamp the load in this way between the lift forks 160 and the support member 1 10. Thus clamped a load can be safely lifted and transported. The load securing device 100 is attached to a lifting slide 150, which carries the two lifting forks 160 and at one

Mast (not shown) of a material handling vehicle (not shown) can be moved vertically.

2 shows a section of a load securing device 100 according to the invention in a three-dimensional representation from the rear with activated holding element 1 10. From this perspective, it can be seen that the gas spring 140 as

Compression spring in the illustrated activated position of the holding member 1 10 is stretched. It engages on the one hand on the retaining element 1 10 itself, on the other hand on a lever element 1 13, which is attached to the yoke 1 1 1. In this lever element 1 13 and the rotation axis 1 12 is mounted, wherein the gas pressure spring 1 12 against the x direction below the axis of rotation 1 12 engages the lever member 1 13 and so generates a torque about the axis of rotation 1 12. This torque acts in such a way that the retaining element 110 would pivot upward, that is to say in the x-direction, if this were not prevented by the supporting elements 120 acting against the guide rail 130 via wearing elements 121. If the load-securing device on the guide rails 130 continues to move vertically counter to the x-direction so far that the support elements 120 are in the area of the curved paths 131 of the guide rails 130, the support elements 120 can no longer counteract the torque and the holding element 1 10 pivots in the

Clockwise upward, that is in the x-direction, about the axis of rotation 1 12. Fig. 3 shows a load securing device 100 according to the invention with activated

Retaining element 1 10 in a side view. The holding element has a horizontal extent D in the activated state, measured between the axis of rotation 12 and the maximum front extent. The masts 151 of the load-securing device 100 are not in the positive y-direction beyond those in the positive y-direction

Front edge of the lifting carriage 150 extended.

Fig. 4 shows a load securing device 100 according to the invention with activated holding element 1 10 in a view from above. The load securing device 100 has two masts 151, wherein in one of the masts 151 a

Height adjustment device 1 15 acts in the form of a Hydraulikkobens. About this hydraulic piston 1 15, the holding member 1 10 vertically, that is in

or are moved against the x-direction. In particular, the deactivated holding element 1 10 via the height adjustment device 1 15 for

Activation over the region 131 of the curved path in the guide rail 130 vertically in the x direction or vice versa the activated holding element 1 10 via the height adjustment device 1 15 for deactivation under the region 131 of the curved path in the guide rail 130 against the x direction vertical

be moved. If the holding element 1 10 is activated, it can over the

Height adjustment device 1 15 are moved vertically in a maximum position in the x direction. In this position, a load may be received with the load receiving member 160. When the load rests on the load-receiving element 160, the holding element can be displaced vertically against the x-direction via the height adjustment device 15 in such a way that it rests on the surface of the load and the load is clamped between the load-receiving element 160 and the holding element 1 10 safe lifting and transporting of the load is possible.

Fig. 5 shows a load securing device 10O according to the invention in one

The holding element 1 10 is located near the lower maximum position in which it is still activated, that is, in which the support member 120 is still in the vertical region of the guide rail 130 outside of the region 131 of the curved path located.

Between the region 131 of the cam track in the guide rail 130 and the upper, in the x-direction end of the guide rail 130 is the guide rail 30 with the length H _F , wherein the holding member 1 10 over the length

H _{F is} vertically displaceable in the activated state. H _F is at least as large as the maximum extent D of the holding member 1 10 seen from the rotation axis 1 12 from. In these geometric conditions, the holding element 1 10 can be folded away in the deactivated state substantially perpendicular to the load-receiving element 160, so that the lifting slide 150 unrestricted by the

Load securing device 100 can also be used in all cases in which a load securing device 100 is not required or even a hindrance. FIG. 6 shows a load-securing device 100 according to the invention in a three-dimensional representation from the front with the holding element 110 deactivated. In this case, H _{F is} greater than the extent D of the holding element 1 10. The holding element 1 10 is substantially perpendicular to the load-receiving element 160, that is, pivoted substantially parallel to the masts 151 in the vertical. Thereby, the entire depth of the load receiving member 160 is available for receiving a load. No part of the load securing device 100 projects beyond the masts 151. Thus are the moving parts of the

Load securing device 100 in a protected position. The masts 151 themselves do not protrude beyond the lifting slide 150 in the positive y-direction, so that the maximum depth of the lifting forks 160 is available for load-bearing.
