Description

The invention relates to a longitudinal strand element for a shaft of an elevator installation and a longitudinal section for precisely this application.

Lifts serve as generally stationary conveyors for people and / or loads, with a lift cage typically being moved up and down a guide.

An elevator consists of a large number of assemblies in order to cover the bandwidth of the functions provided on them. Many of these assemblies consist of two subsystems, namely a moving subsystem and a rigid subsystem. The rigid subsystems are located either at significant locations or along the shaft. Each of these components realizes very specific tasks.

A combination of functions is used in known lifts only to a limited extent. This has the consequence that most of the components are designed as independent units and are also mounted as such.

This results in the assembly and storage a considerable effort that leads to high costs.

The publication WO 98/18709 A describes a guide rail for an elevator with a central portion, the a base and two flange portions each extending from the base. In addition, connections to a shaft are provided. The guide rail carries two lateral sections, each having a first side and a second side. Thus, guide surfaces are formed for a car and a counterweight.

The publication JP 61 166484 A describes guide rails for a shaft of an elevator installation, which have a connection to the shaft. The guide rails are divided into partitions, each assigned a function. For positioning of guide rails arranged on one another, interlocking grooves and projections are provided.

It is a longitudinal strand element with the features of claim 1 and a longitudinal strand according to claim 10 presented.

A manhole element is intended for use in a shaft of an elevator installation and has a longitudinal rail element and a connection to a shaft. In this case, the longitudinal strand element or the longitudinal strand is subdivided into a plurality of partitions, each partition being assigned a function.

The shaft element or shaft segment described thus represents a device that combines many of the stationary subsystems mentioned to form an assembly. This assembly consists of a longitudinal string element or longitudinal strand segment and a connection to the shaft. The module can be arranged once or opposite, diagonally or in all four corners in the shaft.

In an embodiment, the longitudinal rail element provides a partition for runway guides in addition to a partition for the running surfaces for car guides. The treads may have a different surface than the rest of the shaft element. Furthermore, the treads may be at an angle to each other.

The running surfaces for the run-flat guidance can be identical to the running surfaces for the car guides or as separate running surfaces. Furthermore, the joints of the running surfaces between the longitudinal string members can be designed to overlap.

In an embodiment, a partition for the braking surfaces for safety gears or braking devices is provided. It is possible that the braking surfaces have a different surface than the rest of the shaft element, the braking surfaces are identical to the running surfaces for the car guides or running as independent treads, the braking surfaces have a different material than the packing, the thickness of the packing can be changed so that the distance of the braking surfaces to the required rail head thickness of the safety gears or the required brake disc thickness of the braking device can be adjusted, and that the shocks of the braking surfaces between the longitudinal rail elements are performed overlapping.

The described shaft element can be produced in various ways. Thus, the unwinding of the individual parts can be individually cut or stamped from metal sheets or so-called tailored blanks and then folded or embossed. Alternatively, the items may be made from tubes that are forced into their final shape by internal high pressure forming. Another possibility provides that the items are made of flat materials, which are formed by means of a strand profiling and then cut to length.

It is also possible that the individual parts are produced discontinuously as individual fiber composite components. Furthermore, the profiles of the items can be molded by Pultrusionstechnologie and then cut to length.

For mounting the shaft element can be moved in different ways. Thus, the individual modules can be individually stacked and connected to the shaft, the connections to the shaft allow sliding in the longitudinal direction. Alternatively, the individual modules are suspended one above the other mounted in the shaft, with only one connection is rigid and allow the remaining connections a sliding in the longitudinal direction. Another possibility provides that the individual modules are mounted one above the other suspended in the shaft, wherein a continuous connection is used, which is elastic enough to equalize the bays.

In an alternative approach, the strand is supplied in the elastic state, unrolled in the shaft and then fixed in its final position, for example by curing or vacuuming. Furthermore, the individual parts can be produced discontinuously as individual fiber composite components. It is also possible that the profiles of the individual parts are molded by means of a pultrusion technology and then cut to length.

In an embodiment of the longitudinal strand element, the connection consists of a continuous element. This connection compensates for the unevenness of the shaft wall and ensures a secure hold of the longitudinal strand. Alternatively, the connection consists of several elements distributed over the longitudinal strand.

In use, the connection secures the longitudinal strand in the horizontal directions and allows vertical sliding. In a particular embodiment, the connection also fixes the vertical direction. The connection can be done non-positively by means of adhesives or foams or positively with adjustable brackets or brackets.

The described longitudinal strand element serves for a shaft of an elevator installation and is subdivided into a plurality of partitions, each partition being assigned a function. The longitudinal rail element has at least one partition, which provides running surfaces for a car guide. Furthermore, the longitudinal string element has a calibration device according to claim 1.

In an embodiment, the partition for the main drive has an increased surface friction value in the longitudinal-arm element.

Alternatively, the main drive partition has a gearing or a hole pattern.

The longitudinal rail element described can have at least one partition which is provided for aligning the longitudinal strand element in the shaft.

Furthermore, the longitudinal rail element can have at least one partition which, in addition to running surfaces for a car guide, provides running surfaces for an emergency running guide.

In an embodiment, the longitudinal rail element has at least one partition which provides braking surfaces for safety gears or brake devices.

The presented longitudinal strand is intended for a shaft of an elevator installation and comprises a number of the longitudinal suspension elements described above.

This longitudinal strand is typically made of a thin-walled material. The cross section of the profile of the longitudinal strand can be designed both open and closed. This represents a significant difference to conventional guide rails made of a homogeneous material, which also creates new aspects in terms of manufacturing, logistics, assembly and maintenance.

The joints between the longitudinal string members may be formed overlapped at least limited to individual partitions.

The overlap can be given according to a tongue and groove principle.

Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.

FIG. 1 illustrates five ways of arranging longitudinal strands in a hoistway.

The illustration shows an elevator shaft 2 with a car 4, wherein in each case at least one longitudinal strand 6 is arranged in the elevator shaft 2. Thus, up to four longitudinal strands 6 are provided in the elevator shaft 2, which can be arranged opposite one another in corners of the elevator shaft 2. If a plurality of longitudinal strands 6 are provided, a symmetrical arrangement of these in the elevator shaft 6 is appropriate. Also positions for the longitudinal strands are possible, the mirror image of the in FIG. 1 are shown positions.

In FIG. 2 are shown different cross-sectional profiles of the presented longitudinal strand or the longitudinal strand element. These longitudinal string members, which form the longitudinal strand when assembled, are secured in the shaft via connections.

The longitudinal strand usually consists of a thin-walled material. The cross section of the profile can, like FIG. 2 shows, closed or open.

Thus, reference numeral 10 shows an open profile of a longitudinal strand having a substantially U-shape with a base 12 and two legs 14.

Reference number 20 shows a profile similar to the profile designated by reference numeral 10, which likewise has a base 22 and two tapered limbs 24.

Reference numeral 30 designates a likewise open profile with a base 32, two legs 34 extending from this base at right angles, and two side flaps 36, which extend in each case at substantially opposite ends of the legs 36 at substantially right angles.

The profiles 10, 20 and 30 can each be formed from a flat plate by bending or by assembling individual plates or sheets.

Reference numeral 40 designates another open profile with a base 42, two legs 44, a side flap 46 and a rib 48.

Another profile 50 is closed with a base 52 and two legs 54, which are connected to a base plate 56 such that the closed profile 50 results.

Reference numeral 60 designates another profile which is wave-shaped.

Furthermore, reference numeral 70 shows a closed profile comprising a base plate 72 with a diamond-shaped quadrangular unit 74 connected thereto, which in turn is composed of four plates 76.

The profiles shown illustrate that different cross sections can be used for the longitudinal section. The concrete design of the longitudinal strand is adapted to the special requirements of the elevator and the external conditions, such as the space in the shaft. The profiles shown represent only an arbitrary selection of possible profiles and can also be combined as needed.

In FIG. 3 is another possible cross-sectional profile of a longitudinal strand, indicated generally by the reference numeral 100, shown.

It should be noted that the presented longitudinal strand 100 is subdivided into different partitions to which the functions mentioned and the materials required for this purpose are assigned in this embodiment. The material used can be steel, non-ferrous materials, plastics and fiber composites. It can be provided that the surfaces are appropriately finished.

In FIG. 4 are joints between longitudinal columns shown. The longitudinal strand is manufactured in individual elements or segments. The transition points between the segments are designed so that they allow a subsequent replacement of individual segments within the already mounted longitudinal strand.

For the partitions that require continuous continuation of the surfaces, the transition point is overlapped. The crossing points can be executed as follows:

Reference numeral 200 designates a transition in which a first element 202 and a second element 204 lie on one another with smooth bearing surfaces.

Reference numeral 210 shows a transition in which a first element 212 and a second element 214 lie on top of each other with corresponding stepped bearing surfaces, so that the transition point is formed overlapping.

Reference numeral 220 denotes another overlapping transition with a first element 222 and a second element 224.

Another stepped transition is shown with a slope in the bearing surfaces with reference numeral 230.

The transition may also be implemented as a combination of two or more principles.

The individual parts for the longitudinal strand can be produced by individually cutting or punching the unwindings of the individual parts from metal sheets or tailored blanks and then folding or embossing them. Alternatively, the items may be made from tubes that are forced into their final shape by internal high pressure forming. Other alternative approaches provide that the items are made from sheet materials that are molded by means of a Strandprofilieranlage and then cut to length be that the items are prepared discontinuously as a single fiber composite components, or that the profiles of the items are formed by Pultrusionstechnologie and then cut to length.

At the ends of the longitudinal strand segments are more partitions that have a right angle to the cross section of the longitudinal strand segments.

This is a partition to provide balancing areas for possible building sinks and a partition to provide balancing areas for possible temperature expansion.

FIG. 5 shows a partition 300 of the longitudinal strand for a braking surface. This braking surface basically consists of a carrier material for the braking surfaces and a filling material. The nature of the braking surfaces may differ from the rest of the longitudinal strand. By changing the thickness of the filling material, the geometry can be changed.

FIG. 5 FIG. 12 shows the detailed structure of the partition 300 including an upper brake surface 302, a filler layer 304, and a lower brake surface 306. Between the lower braking surface 306 and the filling material layer 304 is the remaining longitudinal strand 308.

In FIG. 6 possible partitions of the longitudinal strand are reproduced for a main drive.

The main drive partition can be characterized by increasing the surface friction value and / or incorporating a gearing 400 or a hole pattern 402. In this case, the partition for the emergency drive be designed according to the partition for the main drive.

In FIG. 7 possible partitions for a stop means are shown, which are preferably arranged in the center axis of the longitudinal strand.

The illustration shows as a first possibility a section 500 of a longitudinal strand 502 with an opening 504.

In a further variant 510, an eyelet 514 is anchored in a main body 512 of a longitudinal strand.

The longitudinal string may have partitions that are used to align the longitudinal string in the hoistway. For this, gauges or gauges can be attached to the defined locations of the partition. This is illustrated in FIG.

The illustration shows a left longitudinal strand 602 and a right longitudinal strand 604, between which a gauge 606 is arranged for alignment. This jig 606 is fixed to the left longitudinal strand 602 with a clamping device 608. A tip 610 of the jig 606 serves to align the right 604 or left longitudinal strand 602.

Alternatively, elements can be incorporated in the partition, which can be referenced or process the signals with which the current position of the longitudinal strand can be determined. These may, for example, be inclination sensors which are inserted in the fiber composite and, e.g. be read out wirelessly.

At the ends of the individual segments of the longitudinal strand are according to the invention calibration devices, which align the cross sections of the profiles to each other. Such a calibration device according to the invention is in FIG. 9 represented and designated generally by the reference numeral 700.

The illustration shows an upper longitudinal rail element 702, a compensation slot 704, a first connection 706, an upper calibration sleeve 708, centering pins 710, a lower calibration sleeve 712, a second connection 714 and a lower longitudinal rail element 716.

For alignment, the precisely manufactured sizing cuffs 708 and 712 are slipped over and joined to the ends of the longitudinal string members 702 and 716. In order for the ends to better conform to the sizing cuffs 708 and 712, the ends may also be slotted, as realized with the compensation slot 704. During assembly, one of the calibration collars 708 and 712 is brought into congruence with the other via the centering pins 710. In this way, a stepless transition can be realized.

The longitudinal strand may have partitions serving as assembly compartments for other elevator components, such as shaft copying and / or shaft lighting and / or hanging cable fastening and / or linear motor parts, etc. For grooves, holes or threads can be incorporated into the longitudinal strand. FIG. 10 , explains possible versions.

The illustration shows a first longitudinal strand with a bore 802, a second longitudinal strand 804 with a threaded fitting 806 and a third longitudinal strand 808, which is designed grooved.

Furthermore, the longitudinal string can have a partition which is used for the elevator copying by serving as a running surface for a moving speedometer or by having a coding that can be read out by a moving subsystem. This coding can be applied as a coded tape on the longitudinal strand or incorporated into the longitudinal strand. Instead of a band, individual reference points, such as transponders, can be used. However, the coding can also be realized by the fact that the partition is coated differently, magnetized or perforated.

Furthermore, the longitudinal string may have a partition which itself carries data or energy or is incorporated in the lines carrying data or energy. The transition points of the segments or lines are designed so that they transport the data or energy, this can be realized for example by connectors.

In the longitudinal strand sensors can be incorporated or applied, which can detect the deflections or material damage. These can be DMS, which are read out wirelessly. As a result, statements about the condition of the longitudinal string can be made.

The longitudinal string is typically attached by means of a connection to the shaft. This joint regularly compensates for the unevenness of the shaft wall and ensures a secure hold of the longitudinal strand. The connection may consist of a continuous element or of several elements distributed over the longitudinal strand.

FIG. 11 shows possible connections in the shaft. On the left side of the figure is a shaft 850 with a longitudinal string 852, wherein the longitudinal strand 852 is connected to the shaft 850 via a continuous connection 854. The connection 854 is designed, for example, flexibly, that unevenness of the shaft 850 is compensated.

On the right side, a shaft 870 is shown, to which a longitudinal strand 874 is connected via individual distributed connections 872.

The compound fixes the longitudinal strand in the horizontal directions and allows vertical sliding. In a special version, the connection also fixes the vertical direction. The connection can be made non-positively by means of adhesive or adhesive materials or positively with adjustable brackets or brackets.

When using adhesive materials, the longitudinal strand is brought into the correct position. Then the space between the longitudinal string and the shaft wall is filled with adhesive or foam. After the connection has hardened, the further assembly is continued. This process can also take place continuously.

In FIG. 12 is a positive connection represented by means of console. The illustration shows a connection 900 with a Kalibriermanschette 902, a first connecting element 904 for the longitudinal strand, a second connecting element 906 to the console 901, adjusting screws 908 and fastening screws 910 to the shaft wall.

Reference number 912 shows the horizontal adjustment range and reference number 914 the vertical adjustment range.

For larger heights, it may be appropriate that the longitudinal strand in the flexible state is preferably supplied rolled up to the shaft and then brought in this unrolled in the correct position and then fixed. The fixing can be realized by sucking or blowing in air or by curing. The curing can be done by UV light, air components or by supplying a chemical accelerator.

FIG. 13 illustrates a possible assembly process when the connection is realized via an adhesive material.

The illustration shows a flexible, coiled longitudinal strand 950. This is in common with a dispenser 956, a UV lamp 958, and a guide 960 on a mobile mounting platform 990 driven by a friction wheel drive 952 and 968 and perpendicular to pressure cylinders 954 and 970 is led up.

With the donor 956, the adhesive material is applied and cured with a UV lamp 958. Behind a guide 960 of the longitudinal strand, the adhesive material is cured 962 and fixed in the lower region of the longitudinal strand 964 on the shaft wall 966.

Furthermore, a controller 972 is provided for controlling the process.
