Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hydraulic moving device that adjusts a relative position in a horizontal direction between two objects to perform alignment, and more specifically, attaches the hydraulic moving device to one object, and horizontally and between the two objects. The present invention relates to an alignment hydraulic transfer device capable of adjusting a relative positional relationship in a vertical direction.
[0002]
[Prior art]
Conventionally, as a hydraulic moving apparatus for alignment used in such a case, for example, the one shown in Japanese Patent Application Publication No. 42742 (1974) is already widely known.
[0003]
In other words, in this case, a hydraulic jack is movably mounted on a base with a sliding board interposed therebetween, and the two hydraulic cylinders are horizontally moved while maintaining a right angle between the base and the hydraulic jack. The two hydraulic cylinders are connected to the base and the hydraulic jack so as to be swingable in the horizontal direction by fixing only the connection point of one hydraulic cylinder to the hydraulic jack.
[0004]
Then, one object is placed and supported on the hydraulic jack, and in this state, the two hydraulic cylinders are selectively pushed and pulled to adjust the moving direction of one object to the other object together with the hydraulic jack. And move it on the base so that the relative positional relationship of both objects in the horizontal direction is matched.
[0005]
After that, the hydraulic jack is expanded and contracted to move one object up and down, and thus the two objects are aligned by matching the relative positional relationship between the two objects in the vertical direction.
[0006]
[Problems to be solved by the invention]
Therefore, according to this, two objects are moved, such as moving heavy objects to a desired position, such as relocation work of buildings and houses accompanying land readjustment, or alignment of each hull block by block shipbuilding method. It is extremely suitable for use in the case where the positional relationship is adjusted and matched.
[0007]
However, on the other hand, it does not apply to moving objects such as piers, gangways, boarding bridges, freighters and other piers, or loading platforms, trailers and tractors. When the positioning hydraulic movement device is installed, the positioning hydraulic movement device jumps due to vibrations generated during movement, causing an impact and the movement of the mounted object itself becomes unstable. There is a problem that damage is caused to the fitting hydraulic transfer device and the mounted object.
[0008]
Not only that, but especially for trailers and tractors or bridge girders and piers, where two objects are placed one on top of the other and then connected to each other, Since the hydraulic jack of the moving device protrudes greatly from the pedestal, there is a problem that a large step is formed between the two objects after alignment, and the connecting operation cannot be performed.
[0009]
Accordingly, an object of the present invention is to allow the positioning hydraulic moving device to be installed on a moving object by limiting the jumping of the positioning hydraulic moving device from the mounted object due to vibration during movement, and to provide two objects of the positioning hydraulic moving device. An object of the present invention is to provide an alignment hydraulic transfer device that can connect these two objects while keeping the projecting dimension between them to a minimum.
[0010]
[Means for Solving the Problems]
In the present invention, the above-described object is to provide a mounting space surrounded by a plane board, a side wall board, and a bowl-like board on the mounted object, and a hydraulic pressure provided with a flange that engages with the inner surface of the bowl-like board inside the installation space. The jack is placed in such a way that one end can protrude from the bowl to the outside while being limited to relative displacement in the vertical direction between the plane board and the bowl, and the jack can be moved in any direction in the horizontal direction. On the other end of the flat plate and the inner surface of the flat plate, a sliding plate and a sliding plate with low frictional force are arranged, while maintaining a right angle between the hydraulic jack and the side wall plate, the two hydraulic cylinders are oriented horizontally. These hydraulic cylinders are mounted on the side wall so that they can swing horizontally, and one of the hydraulic jacks can swing horizontally, and the other swings horizontally. This is achieved by constraining and connecting.
[0011]
In other words, with the above-described configuration, the positioning hydraulic movement device can be operated by sliding the flange provided on the other end on the bottom side of the hydraulic jack by engaging the flange and the bowl-shaped board (at the time of inversion) at the normal time. The weight is supported by the contact between the moving plate and the flat plate (when standing upright), and the flat plate or bowl-shaped plate is held in the mounting space provided on the mounted object while limiting the amount of hydraulic jacking up. .
[0012]
Further, in addition to the above, the other part of the positioning hydraulic movement device greatly extends toward the mounting space in the opposite direction from the positioning surface of the mounting object with respect to the other object, and between the two objects. The protrusion dimension of the positioning hydraulic transfer device is kept to a minimum.
[0013]
Thus, even if the positioning hydraulic movement device is mounted on a moving object, the positioning plate or bowl-like plate limits the jumping of the positioning hydraulic movement device due to vibration generated during movement of the mounting object. It is also possible to prevent the movement of the mounted object itself from becoming unstable, or to prevent the positioning hydraulic transfer device and the mounted object from being damaged.
[0014]
Furthermore, even when the mounted object and the other object are objects that are connected to each other after alignment, the alignment operation creates a large step between the mounted object and the other object, thus enabling connection work. Eliminate the fear of disappearing.
[0015]
Moreover, in addition to these, at the time of alignment operation, one or both of the objects are moved to move both objects to a relative positional relationship within a predetermined range, and the hydraulic jack of the alignment hydraulic transfer device is extended from this state. Push the tip of the telescopic rod against the other object, and apply a tension force between the two objects with a hydraulic jack while pressing the sliding board against the sliding plate of the flat board with the reaction force.
[0016]
After that, the two hydraulic cylinders installed in the horizontal direction while maintaining a right angle between the hydraulic jack and the side wall board are selectively pushed and pulled, and the sliding board and the sliding board are slid by the pushing force of these two hydraulic cylinders. The relative horizontal position of the mounted object and the hydraulic jack is adjusted while sliding between the contact plates.
[0017]
In this case, since only the connection point of one hydraulic cylinder to the hydraulic jack is connected by restraining the swing in the horizontal direction, the hydraulic jack performs a rotating motion with respect to the one hydraulic cylinder. Move without
[0018]
As a result, both objects move to a predetermined position with respect to the larger object with the smaller moving resistance according to the selective push-pull operation and operation amount of the two hydraulic cylinders through the side wall board and the hydraulic jack. Then, both objects are aligned.
[0019]
After the positioning operation of both objects is completed, the hydraulic jack is contracted and separated from the other object, and the two hydraulic cylinders are moved to the intermediate operation position to return the positioning hydraulic moving device to the initial state. .
[0020]
As a result, the hydraulic transfer device for alignment returns to the normal state as described above, and its own weight is supported by the bowl-like board or plane board, and also the jumping up by these plane board or bowl-like board is restricted. Thus, it is held in the mounting space to prepare for the next alignment operation.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
[0022]
FIG. 1 shows an alignment hydraulic transfer device 1 according to the present invention. One object (attachment object) 2 on the attachment side of two objects 2 and 3 to be aligned is shown in cross section as shown in FIG. A mounting space 7 is formed by being surrounded by the plane board 4, the side wall board 5 and the bowl-like board 6 (of course, it may be attached separately).
[0023]
Inside the mounting space 7, a hydraulic jack 9 having a flange 8 is stored in an inverted state, and the flange 8 is sandwiched between a sliding plate 10 made of a low friction material such as Teflon and the like of the bowl-shaped plate 6. The hydraulic jack 9 is placed on the inner surface so as to be movable in the horizontal direction via the sliding board 10.
[0024]
At the tip of the telescopic rod 11 extending from the hydraulic jack 9, a contact panel 12 is disposed so as to be able to project from the bowl-shaped board 6, and the projection from the bowl-shaped board 6 when the telescopic rod 11 is compressed most. The dimensions are kept to a minimum.
[0025]
The contact board 12 is for absorbing a difference in inclination between the telescopic rod 11 and the other object 3, and is generally used widely in an outrigger such as a crane truck. In this manner, the end of the telescopic rod 11 in the hydraulic jack 9 is pivotably connected via the spherical body 13.
[0026]
For this reason, when it is not necessary to absorb the inclination at the time of contact, the contact disk 12 is fixed to the distal end of the telescopic rod 11 without the spherical body 13 or the distal end of the telescopic rod 11. Needless to say, may be directly applied to the other object 3.
[0027]
Further, a sliding plate 15 made of the same low friction material is attached to the bottom side which is the upper end of the hydraulic jack 9 through a plate 14, and the sliding plate 15 is stretched on the inner surface of the plane plate 4. It is opposed to the sliding contact plate 16 made of the material with a slight gap left.
[0028]
Thus, the hydraulic jack 9 is restricted in its vertical movement by the abutment between the sliding plates 10, 15 and the bowl-like board 6 and the plane board 4, and by the sliding contact between the bowl-like board 6 and the sliding board 10. 9 is supported so as to be movable in all directions in the horizontal direction.
[0029]
On the other hand, between the side wall plate 5 and the hydraulic jack 9 forming the mounting space 7, two hydraulic cylinders 17 and 18 are interposed so as to be swingable in the horizontal direction while maintaining a right angle state. .
[0030]
As shown in FIG. 2, one end of each of these hydraulic cylinders 17 and 18 is connected to the side wall board 5 by vertical connection pins 19 and 20 so as to be swingable in a horizontal direction.
[0031]
On the other hand, the other end of the hydraulic cylinder 17 is pivotally supported by the vertical connection pin 21 so as to be swingable in the horizontal direction, and the other end of the hydraulic cylinder 18 is connected to the hydraulic jack 9 in a horizontal connection with different directions. The pins 22 are connected by restricting the swinging in the horizontal direction.
[0032]
Next, the operation of the positioning hydraulic transfer device 1 configured as described above according to the present invention will be described.
[0033]
In a normal state, the hydraulic jack 9 is supported by its own weight by the engagement of the flange 8 and the bowl-like plate 6 via the sliding plate 10 with respect to the mounted object 2, and the engagement between the two and the plane plate 4 and The hydraulic jack 9 is held in the mounting space 7 provided in the mounting object 2 while restricting the jumping of the hydraulic jack 9 by the engagement with the sliding board 15.
[0034]
Moreover, in this state, the part of the hydraulic jack 9 extends toward the mounting space 7 in the opposite direction from the alignment surface of the mounting object 2 with respect to the other object 3, and the mounting object 2 and the other The projecting dimension of the hydraulic jack 9 to the object 3 is kept to a minimum.
[0035]
As a result, even if the mounting object 2 to which the positioning hydraulic movement device 1 is attached is a moving object, the hydraulic jack 9 jumps and jumps due to vibration generated during the movement of the mounting object 2. 6, the movement of the mounting object 2 itself becomes unstable and the positioning hydraulic transfer device 1 and the mounting object 2 are prevented from being damaged.
[0036]
In addition to this, even when the mounting object 2 and the other object 3 are objects that are connected to each other after the positioning, a large amount of space between the mounting object 2 and the other object 3 is obtained by the positioning operation. It is possible to eliminate the fear that a step may be formed and connection work cannot be performed.
[0037]
On the other hand, at the time of alignment operation, one or both of the mounted object 2 and the other object 3 is moved to move them to a relative positional relationship within a predetermined range, and the hydraulic jack 9 is extended from this state to extend the telescopic rod 11. The body portion of the hydraulic jack 9 is pushed up by a reaction force while pressing the tip against the other object 3.
[0038]
As a result, the flange 8 of the hydraulic jack 9 is lifted away from the bowl-shaped plate 6 on the mounting object 2 side, and the sliding plate 15 provided on the plate 14 is pressed against the sliding contact plate 16 on the flat plate 4 side. A tension force is applied between the mounted object 2 and the other object 3 by the hydraulic jack 9.
[0039]
Thereafter, the two hydraulic cylinders 17 and 18 interposed in the horizontal direction while maintaining a right angle between the hydraulic jack 9 and the side wall disc 5 are selectively pushed and pulled, and the two hydraulic cylinders 17 and 18 are The relative horizontal position of the mounted object 2 and the hydraulic jack 9 is adjusted while sliding between the sliding plate 15 and the sliding contact plate 16 by the pushing and pulling force.
[0040]
In this case, since only the connection point between the hydraulic jack 9 and the hydraulic cylinder 18 is connected by the horizontal connection pin 22, the hydraulic jack 9 moves without rotating with respect to the hydraulic cylinder 18. .
[0041]
As a result, the mounted object 2 and the other object 3 have the smaller movement resistance according to the selective push-pull operation and the operation amount of the two hydraulic cylinders 17 and 18 through the side wall board 5 and the hydraulic jack 9. To the predetermined position, and the positioning of the mounted object 2 and the other object 3 is performed.
[0042]
Further, after the positioning operation of the mounted object 2 and the other object 3 is finished, the telescopic rod 11 of the hydraulic jack 9 is contracted and separated from the other object 3, and the two hydraulic cylinders 17, 18 is moved to the intermediate operation position to return the positioning hydraulic transfer device 1 to the initial state.
[0043]
At this time, the hydraulic jack 9 is slid along the bowl 6 while being supported by the bowl 6 through the sliding board 10 of the flange 8 and returns to the initial position.
[0044]
Therefore, when the weight of the hydraulic jack 9 is large, the sliding resistance can be lowered by interposing the sliding plate 10 between the bowl-like plate 6 and the flange 8 as in the present embodiment. Although it is desirable, when the weight of the hydraulic jack 9 is not more than a certain level and the sliding resistance is small, it is not always necessary to support the hydraulic jack 9 via the sliding board 10.
[0045]
In this way, the positioning hydraulic transfer device 1 returns to the normal state described above and is stored in the mounting space 7, and the engagement of the hook-like plate 6 and the flange 8 causes the hydraulic jack 9 to be moved. The plane board 4 and the bowl-like board 6 also restrict the jumping up while supporting its own weight.
[0046]
In addition to this, even if the protruding size of the hydraulic jack 9 to the alignment surface of the mounted object 2 is kept to a minimum and the mounted object 2 and the other object 3 are connected to each other, This facilitates the connecting operation and prepares for the next alignment operation.
[0047]
In the above-described embodiment of the present invention, the case has been described in which the hydraulic jack 9 in the positioning hydraulic moving apparatus 1 is inverted and mounted on the upper object 2. It can be easily understood on the basis of the above description that the positioning device 9 can be used even if the positioning device 9 is mounted on the lower object 3 side in the upright state.
[0048]
【The invention's effect】
As described above, according to the present invention, even when the positioning hydraulic movement device is attached to a moving object, the positioning hydraulic movement device is restricted from jumping due to vibration generated during the movement of the object. Therefore, it is possible to prevent the movement of the mounted object itself from becoming unstable and the positioning hydraulic transfer device and the mounted object from being damaged.
[0049]
In addition, in this case, the projection size of the positioning hydraulic movement device between the two objects can be kept to a minimum, so that a large step is formed between the two objects after the positioning operation, and the connection work cannot be performed. Can also be removed.
