[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1 , Figure 2 and Figure 5 Existing gantry cranes can be assembled with modular devices, and the connecting parts that connect different modules of the gantry crane are not convenient for limiting the connection points of the modules. In order to solve this technical problem, this embodiment discloses the following technical content;

[0027] The first vertical plate 2 and the second vertical plate 8 are both provided with a limiting mechanism in the middle. The limiting mechanism is composed of a connecting plate 10, a storage groove 11, a threaded rod 12 and a limiting plate 13. The lower surface of the connecting plate 10 is provided with a storage groove 11 in the middle, and the inner side of the storage groove 11 is in contact with the outer side of the top of the first vertical plate 2 and the second vertical plate 8. The upper end of the connecting plate 10 is threadedly connected to the threaded rod 12, and the inner end of the threaded rod 12 is rotatably connected to the limiting plate 13.

[0028] After the connecting module is assembled, place the connecting module at the connection point of the gantry crane module. Then, the module needs to be limited. Fix both ends of the connecting plate 10 to the first vertical plate 2 or the second vertical plate 8 with bolts. As needed, the connecting plate 10 can be installed at different positions at the upper and lower ends of the first vertical plate 2 and the second vertical plate 8. After the connecting plate 10 is installed, rotate the threaded rod 12 so that the limiting plate 13 can move inward to clamp and limit the module, preventing the position of the connecting module from shifting during connection.

[0029] Example 2: Existing gantry cranes can be assembled into modular devices, but the connecting components are not easy to assemble stably. Furthermore, gantry cranes consist of multiple modules, making it inconvenient to connect different modules. Therefore, this example uses the following technical solution: Figures 1-4 As shown;

[0030] The first connecting plate 1 is fixedly connected to the upper and lower ends of the outer side of the first vertical plate 2, and the first vertical plate 2 has an elongated hole 3 in the middle. The first connecting plate 1 has a locking block 4 fixedly connected to the middle left side, and the first connecting plate 1 has a locking groove 5 in the middle right side. The locking block 4 and the locking groove 5 are engaged and connected. The first connecting plate 1 and the locking groove 5 both have through holes 6 in the middle, and a stabilizing bolt is connected through the through hole 6.

[0031] The second connecting plate 7 has a locking block 4, a locking groove 5 and a through hole 6 at both ends, just like the first connecting plate 1. The upper and lower ends of the outer side of the second connecting plate 7 are fixedly connected to the second vertical plate 8, and the middle of the second vertical plate 8 is provided with a long strip hole 3. An angle plate 9 is fixedly connected to the outer side of the connection between the first connecting plate 1 and the second connecting plate 7 by bolts.

[0032] According to the dimensions of the connection point of the gantry crane module, the first connecting plate 1 and the second connecting plate 7 are connected together to form a square ring structure. The inner sides of the first vertical plate 2 and the second vertical plate 8 on the sides of the first connecting plate 1 and the second connecting plate 7 are fitted with the outer side of the gantry crane. When assembling the first connecting plate 1 and the second connecting plate 7, the locking block 4 on the first connecting plate 1 or the second connecting plate 7 is engaged with the locking groove 5 opened on the adjacent first connecting plate 1 or the second connecting plate 7. Then, the connecting point of the first connecting plate 1 and the second connecting plate 7 is fixed together by passing the stabilizing bolt through the through hole 6. The assembly is carried out in sequence.

[0033] After the first connecting plate 1 and the second connecting plate 7 are assembled, the assembled connecting module is connected to the gantry crane module. The first vertical plate 2 and the second vertical plate 8 on the sides of the first connecting plate 1 and the second connecting plate 7 are located on the outside of the module. Bolts are used to pass through the elongated holes 3 opened on the first vertical plate 2 and the second vertical plate 8 to fix the first vertical plate 2 and the second vertical plate 8 to the gantry crane module. Since the first vertical plate 2 and the second vertical plate 8 are respectively fixed on the first connecting plate 1 and the second connecting plate 7, fixing the first vertical plate 2 and the second vertical plate 8 is equivalent to fixing the first connecting plate 1 and the second connecting plate 7. Angle plate 9 is provided on the outside of the corner of the first connecting plate 1 and the second connecting plate 7. The upper and lower outer sides of the angle plate 9 are respectively fixed to the first vertical plate 2 and the second vertical plate 8 by bolts. The above are the steps for installing the gantry crane module device.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
