Description

Technical Field

[0001] This utility model relates to the field of warehouse support structures, and more specifically, to a stacker crane overhead rail support structure for the end of a rack aisle. Background Technology

[0002] In automated warehousing systems, aisle ends are critical areas for stacker cranes, inspection equipment, and personnel maintenance. Structural components cannot be placed below aisle ends, but overhead rails must be installed above them to ensure the stacker crane's travel and guidance. If the overhead rails extend directly out, their stability cannot be guaranteed. Therefore, support structures need to be installed at the ends of the racking aisles to support the overhead rails, ensuring their stability and allowing the stacker crane to operate normally.

[0003] Due to the diverse spatial layouts of racking aisles, existing stacker crane overhead rail support structures used at the ends of racking aisles are mostly installed by splicing multiple crossbeams. The support structure's width is limited by the length of the crossbeams, easily leading to variations in aisle width. This makes it difficult to install the support structure stably in the racking aisles, affecting installation and usability, and making it inconvenient to adjust the spacing of the support structure. Furthermore, while the stacker crane normally stops at the stop position via electrical limit switches (such as photoelectric switches) when running along the racking aisles under overhead rail guidance, if the stacker crane experiences operational malfunction or overload, it may crash into the end of the overhead rail. Existing support structures cannot intercept and protect the end of the overhead rail, resulting in poor practicality and safety.

[0004] Therefore, we have made improvements to this by proposing a stacker crane overhead rail support structure for the end of a rack aisle. Utility Model Content

[0005] The purpose of this utility model is to address the current problems of inconvenience in adjusting and adapting the spacing of the support structure, and inconvenience in intercepting and protecting the ends of the ceiling track.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] Stacker crane overhead rail support structures are used at the ends of rack aisles to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] The system includes a mounting bracket and a sliding track. The mounting bracket has a sliding track with an extension plate inside. The extension plate has a positioning groove. A positioning bolt is threaded onto the mounting bracket. A crossbeam is fixedly connected to the extension plate. A first support frame is bolted to the crossbeam. A second support frame is rotatably connected to the first support frame. The other end of the second support frame is bolted into the crossbeam. A third support frame is rotatably connected to the first support frame. Connectors are installed on the first, second, and third support frames. A top rail is bolted to the mounting bracket. A connecting frame is bolted to the frame, a pulley is rotatably connected to the connecting frame, a double-threaded rod is rotatably connected to the connecting frame, a turntable is fixedly connected to the double-threaded rod, a movable plate is threaded to the double-threaded rod, a push plate is rotatably connected to the movable plate, a clamping plate is rotatably connected to the other end of the push plate, an adjusting plate is provided on the connecting frame, a through hole is opened on the adjusting plate, a damper is fixedly connected to the adjusting plate, a buffer plate is fixedly connected to the damper, a damping spring is fixedly connected to the buffer plate, and the other end of the damping spring is fixedly connected to the adjusting plate.

[0010] As a preferred technical solution of this application, the extension plates are symmetrically distributed on the left and right sides of the mounting frame, and the extension plates correspond one-to-one with the first support frame through the crossbeams.

[0011] As a preferred technical solution of this application, the positioning groove is provided in two sets, and the two sets of positioning grooves are symmetrically distributed on the upper and lower sides of the extension plate, with each set of positioning grooves being equidistantly distributed on the extension plate.

[0012] As a preferred technical solution of this application, the cross-section of the connecting frame is "L" shaped, and the pulleys are evenly distributed on the connecting frame.

[0013] As a preferred technical solution of this application, the turntables are symmetrically distributed on the bidirectional threaded rods, and the turntables correspond one-to-one with the push plates via the moving plates.

[0014] As a preferred technical solution of this application, one end face of the card plate is in contact with the inner side of the connecting frame, and through holes are provided at equal intervals on the adjusting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] 1. It is equipped with an extension plate; when adjusting the spacing of the crossbeams, the positioning bolts on the rotating mounting bracket can be disengaged from the positioning grooves of the extension plate. After the extension plate is unobstructed, it can extend from the mounting bracket to adjust the spacing. The positioning bolts can be rotated in the opposite direction and locked into the positioning grooves in the extension plate for fixed positioning. The spacing can be adjusted for installation according to the usage.

[0018] 2. An adjusting plate is provided; when the support structure on the ceiling track slides, it can impact the damper through the buffer plate at the end, and the buffer plate can compress the damping spring on the adjusting plate. The pushing of the damper and the damping spring can play a role in interception and buffering protection. When the adjusting plate moves up and down, it can be blocked by the pulleys on the connecting frame. The rotating turntable drives the moving plates on both sides to move inward through the double-threaded rod. The moving plates can be moved by the push plate pulling the clamping plate. The clamping plate disengages from the through hole of the adjusting plate, and the position of the adjusting plate can be adjusted by sliding. The double-threaded rod is rotated in the opposite direction, which can push the clamping plate into the through hole to position the adjusting plate. Thus, the position of interception and protection can be easily adjusted according to actual needs. Attached Figure Description

The other end of the damping spring 23 is fixedly connected to the adjusting plate 19.

[0033] Example 2:

[0034] The solution in Example 1 will be further described below with reference to its specific working method.

[0035] like Figure 3 As shown, in a preferred embodiment, based on the above method, the extension plates 3 are symmetrically distributed on the left and right sides of the mounting frame 1. The extension plates 3 correspond one-to-one with the first support frame 7 through the crossbeams 6, which can ensure the cooperation between the crossbeams 6 on both sides and the first support frame 7 and other components, and can play a supporting role in the installation.

[0036] like Figure 3 As shown, in a preferred embodiment, based on the above method, two sets of positioning grooves 4 are further provided. The two sets of positioning grooves 4 are symmetrically distributed on the upper and lower sides of the extension plate 3. Each set of positioning grooves 4 is equidistantly distributed on the extension plate 3, which can ensure that the positioning grooves 4 opened at equal angles can be engaged and positioned by the installed positioning bolts 5, thereby improving the adjustment and use effect.

[0037] like Figure 5 As shown, in a preferred embodiment, based on the above method, the connecting frame 12 has an "L" shaped cross section, and the pulleys 13 are evenly distributed on the connecting frame 12, which can ensure that the "L" shaped connecting frame 12 can support the adjusting plate 19 to resist impact.

[0038] like Figure 6 As shown, in a preferred embodiment, based on the above method, the turntables 15 are symmetrically distributed on the bidirectional threaded rods 14. The turntables 15 correspond one-to-one with the push plates 17 through the moving plates 16, which can ensure that the push plates 17 on both sides can smoothly push or pull the clamping plates 18 to move.

[0039] like Figure 6 As shown, in a preferred embodiment, based on the above method, one end face of the card plate 18 is in contact with the inner side of the connecting frame 12, and through holes 20 are provided at equal intervals on the adjusting plate 19, so that the card plate 18 can move smoothly by being supported by the contact of the inner side of the connecting frame 12.

[0040] Specifically, the stacker crane overhead rail support structure, originally intended for use at the ends of rack aisles, should be used in conjunction with: Figure 1-6 When adjusting the spacing of the crossbeam 6, the positioning bolt 5 on the rotatable mounting bracket 1 can be disengaged from the positioning groove 4 of the extension plate 3. After the extension plate 3 is unobstructed, it can be slid out from the slide groove 2 in the mounting bracket 1 to adjust the spacing. The positioning bolt 5 is rotated in the opposite direction, which can cause the positioning bolt 5 to engage with the positioning groove 4 in the extension plate 3 for fixed positioning. The spacing can be adjusted according to the usage situation for adaptation and installation. The joint 10 on the crossbeam 6 and the first support frame 7 and the third support frame 9 can be bolted to the shelf. With the second support frame 8, it can support the crossbeam 6 and the first support frame 7, improving the stability of the support. The ceiling rail 11 bolted on the mounting bracket 1 can slide to install the stacker crane so that the stacker crane can slide on the ceiling rail 11.

[0041] When the support structure on the overhead rail 11 slides, it can impact the damper 21 through the buffer plate 22 at the end, and the buffer plate 22 can squeeze the damping spring 23 on the adjusting plate 19. The pushing of the damper 21 and the damping spring 23 can play the role of interception and buffer protection. When the adjusting plate 19 moves up and down, it can be blocked by the pulley 13 on the connecting frame 12. The rotating turntable 15 drives the moving plates 16 on both sides to move inward through the bidirectional threaded rod 14. The moving plates 16 can be pulled by the push plate 17 to move the clamping plate 18. The clamping plate 18 disengages from the through hole 20 of the adjusting plate 19, and the position of the adjusting plate 19 can be adjusted by sliding. The bidirectional threaded rod 14 is rotated in the opposite direction, which can push the clamping plate 18 into the through hole 20 to position the adjusting plate 19. Thus, the position of interception and protection can be conveniently adjusted according to actual needs. If the stacker crane slides on the overhead rail 11 and an accident occurs, the buffer plate 22 can protect the damper 21 and avoid safety hazards caused by movement overload.

[0042] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, as well as all technical solutions and improvements that do not depart from the spirit and scope of practicality, are covered within the scope of the claims of the present utility model.
