[0002] In large warehouses, hoist trolleys can be installed on tracks between shelves. When goods need to be stored or retrieved, they can quickly move to the designated location, lift the goods, and transport them to the appropriate location in the shipping or storage area. Especially for some heavy goods, such as heavy machinery and steel, the hoist trolley's load-bearing capacity can meet the lifting requirements. It can also be combined with a warehouse management system to realize automated goods handling and storage, improving warehouse space utilization and goods turnover efficiency.

[0003] Existing hoist carts are typically assembled using bolts. The bolt installation process is cumbersome, requiring tools to tighten each bolt individually, and ensuring that the tightening torque of each bolt meets the requirements. This takes a lot of time and affects work efficiency. Therefore, a hoist cart that can be assembled quickly is proposed. Utility Model Content

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a quick-assembly hoist trolley, comprising a crossbeam 1 and a fixed frame 2. A hoist trolley 3 is fixedly connected to the lower surface of the fixed frame 2. A power box 4 is fixedly connected to the outer wall of the fixed frame 2. A bidirectional lead screw 5 is rotatably connected inside the power box 4. The outer wall of the bidirectional lead screw 5 is rotatably connected to the inside of the fixed frame 2. A second fixed plate 12 is threadedly connected to the outer wall of the bidirectional lead screw 5. A rotating column 10 is rotatably connected inside the second fixed plate 12. A second rotating wheel 11 is fixedly connected to the outer wall of the rotating column 10. A first fixed plate 7 is threadedly connected to the outer wall of the bidirectional lead screw 5. A motor 8 is fixedly connected to the outer wall of the first fixed plate 7. The motor 8... The output end is rotatably connected to the inside of the fixed plate 7 and fixedly connected to the rotating wheel 9. The outer wall of the rotating wheel 9 is connected to the outer wall of the crossbeam 1. The outer wall of the rotating wheel 11 is connected to the outer wall of the crossbeam 1. The inner wall of the fixed frame 2 is fixedly connected to the limit rod 6. The inside of the fixed plate 7 and the fixed plate 12 are slidably connected to the outer wall of the limit rod 6. The inside of the power box 4 is provided with a rotating assembly. The rotating assembly includes a worm gear 13. The outer wall of the worm gear 13 is rotatably connected to the inside of the power box 4. The outer wall of the worm gear 13 is fixedly connected to the handwheel 14. The tooth end of the worm gear 13 is meshed with a worm wheel 15. The inner wall of the worm wheel 15 is fixedly connected to the outer wall of the bidirectional lead screw 5.

[0024] Specifically, the fixing frame 2 can fix the hoist crane 3 and the power box 4. The limiting rod 6 can limit and guide the movement of the second fixing plate 12 and the first fixing plate 7. During the rotation of the bidirectional screw 5 inside the fixing frame 2, since the interiors of the first fixing plate 7 and the second fixing plate 12 slide on the outer wall of the limiting rod 6, the bidirectional screw 5 can only move the second fixing plate 12 and the first fixing plate 7 without rotating itself. The handwheel 14 can rotate the worm gear 13, which in turn can rotate the worm wheel 15. The worm wheel 15 can also rotate the bidirectional screw 5. Through the cooperation between the worm gear 13 and the worm wheel 15, the rotation of the bidirectional screw 5 has a self-locking property, meaning that the worm wheel 15 can only be rotated by rotating the worm gear 13, and the worm gear 15 cannot be rotated by rotating the worm gear 15, thus ensuring stability during use.

[0025] Reference Figure 1 and Figure 3 The mounting plate 7 has a sliding connection to the mounting column 16, and the outer wall of the mounting column 16 has a slot 19.

[0026] Specifically, the mounting column 16 can be slid inside the fixing plate 17 to install the fixing plate 17.

[0027] Reference Figure 1 and Figure 3 A fixing plate 17 is fixedly connected to the outer wall of the mounting column 16. A cleaning wheel 18 is rotatably connected to the inner wall of the fixing plate 17. The outer wall of the cleaning wheel 18 is connected to the outer wall of the crossbeam 1. A cylinder 20 is fixedly connected to the outer wall of the fixing plate 17. A limit groove 21 is formed on the outer wall of the cylinder 20. A fixing block 22 is fixedly connected to the inner wall of the cylinder 20. One end of a spring 23 is fixedly connected to the top of the fixing block 22. A sliding block 24 is fixedly connected to the other end of the spring 23. The outer wall of the sliding block 24 is slidably connected to the inner wall of the cylinder 20. A pull column 25 is fixedly connected to the outer wall of the sliding block 24. The outer wall of the pull column 25 is slidably connected to the inner wall of the limit groove 21. A locking column 26 is fixedly connected to the top of the sliding block 24. The outer wall of the locking column 26 is slidably connected to the inner wall of the locking groove 19.

[0028] Specifically, the fixing plate 7 can fix the cylinder 20, the cylinder 20 can fix the fixing block 22, the limiting groove 21 can limit the limiting groove 21, and thus limit the sliding block 24. The spring 23 can push and reset the sliding block 24, and thus push and reset the locking post 26.

[0029] Working principle: When in use, rotating the handwheel 14 causes the worm gear 13 to rotate inside the power box 4, which in turn causes the worm wheel 15 to rotate. This causes the double-acting screw 5 to rotate simultaneously inside the power box 4 and the fixed frame 2, as well as inside the fixed plate 7 and the fixed plate 12. This causes the fixed plate 7 and the fixed plate 12 to move inward. During this inward movement, the fixed plate 7 and the fixed plate 12 will drive the rotating wheel 9 and the rotating wheel 11 to move inward and contact the outer wall of the crossbeam 1. When the rotating wheel 9 and the rotating wheel 11 are moved to their limit, the fixed frame 2 can be quickly installed, thus achieving the effect of quick installation of the hoist crane 3. This achieves the effect of rapid assembly, allowing for quick assembly and commissioning in a short time, improving efficiency, reducing installation time, and saving labor costs.

[0030] Before installation, pulling the pull column 25 causes the sliding block 24 to slide on the inner wall of the cylinder 20, causing the spring 23 to contract under force, which in turn drives the locking column 26 to move downward. Then, through the fixing plate 3 17, the mounting column 16 slides inside the fixing plate 1 7. After that, the pull column 25 is no longer pulled, which causes the spring 23, which is in a contracted state, to rebound and reset, pushing the locking column 26 to reset and slide into the inner wall of the slot 19, thus limiting the mounting column 16 and limiting the fixing plate 3 17. This achieves the effect of quickly installing the cleaning wheel 18, thereby reducing frictional resistance and improving operating accuracy and stability.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
