[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0024] This application discloses an anti-falling device for a gantry hoist, referring to... Figure 1 and Figure 2 The system includes a base plate 1; a caster wheel 2 is fixedly connected to the bottom of the base plate 1; a fixing device 3 is fixedly connected to the front and back of the base plate 1; a column 4 is fixedly connected to the top of the base plate 1; a crossbeam 5 is fixedly connected to the top of the inner wall of the column 4; a moving device 6 is installed inside the crossbeam 5; a locking device 7 is fixedly connected to the front of the moving device 6; a wire rope 8 is fixedly connected to the bottom of the locking device 7; a connecting block 9 is fixedly connected to the bottom of the wire rope 8; and a hook 10 is fixedly connected to the bottom of the connecting block 9. The fixing device 3 ensures that there will be no slippage or displacement during use, providing stronger stability and preventing equipment movement or hoist detachment due to vibration or external forces during operation. The locking device 7 ensures that the suspended object is stable during movement, preventing it from easily shaking or falling off, thus guaranteeing the stability and accuracy of the hoisting process, reducing safety threats to operators and the surrounding environment, and greatly improving workplace safety.
[0025] Reference Figure 1 The fixing device 3 is provided with a fixing plate 301, and a threaded post 302 is threadedly connected to the middle part of the fixing plate 301; by rotating the disc 303, the threaded post 302 can be easily driven to rotate on the fixing plate 301.
[0026] Reference Figure 1A disc 303 is fixedly connected to the top of the threaded column 302, and a stop block 304 is fixedly connected to the bottom of the threaded column 302. By rotating the threaded column 302, the stop block 304 can be driven to make close contact with the ground, thereby fixing the base plate 1.
[0027] Reference Figure 1 The moving device 6 is equipped with a bidirectional threaded rod 601, and a motor 602 is installed at one end of the bidirectional threaded rod 601. The surface of the bidirectional threaded rod 601 is threadedly connected to a moving block 603. The motor 602 drives the bidirectional threaded rod 601 to rotate. The rotation of the bidirectional threaded rod 601 facilitates the movement of the two moving blocks 603 relative to or opposite to each other. The movement of the moving blocks 603, through the locking device 7 and the wire rope 8, facilitates the lifting and lowering of the hook 10 on the connecting block 9.
[0028] Reference Figure 3 The bottom of the movable block 603 is fixedly connected to a limiting block 604, and a limiting groove 605 is provided at the bottom of the limiting block 604; the limiting block 604 serves to limit the movement of the movable block 603.
[0029] Reference Figure 4 The locking device 7 is provided with a fixing block 701. The middle part of the fixing block 701 is provided with an insertion groove 702. An L-shaped block 703 is provided in the insertion groove 702. The other side of the L-shaped block 703 is rotatably connected to a rotating shaft 704. The other side of the rotating shaft 704 is fixedly connected to a connecting plate 705. By inserting the L-shaped block 703 into the insertion groove 702, the rotation of the connecting plate 705 on the rotating shaft 704 facilitates the insertion of the threaded shaft 707, thereby locking the L-shaped block 703.
[0030] Reference Figure 4 A support block 706 is fixedly connected to the bottom of the fixed block 701. A threaded shaft 707 is threadedly connected to the other side of the support block 706. A turntable 708 is fixedly connected to the other side of the threaded shaft 707. By rotating the turntable 708, the threaded shaft 707 can be driven to pass through the connecting plate 705, and the connecting plate 705 can be fixed on the fixed block 701.
[0031] Working principle: The universal wheels 2 facilitate the movement of the device to the desired position. Rotating the disc 303 causes the threaded column 302 to rotate on the fixed plate 301. The rotation of the threaded column 302 ensures that the abutment block 304 makes tight contact with the ground, thus fixing the base plate 1. This ensures that there will be no slippage or displacement during use, providing stronger stability and preventing the equipment from moving or the hoist from falling off due to vibration or external forces during operation. Inserting the L-shaped block 703 into the insertion slot 702 on the fixed block 701 and rotating the turntable 708 facilitates the threaded shaft 707 to pass through... The connecting plate 705 is inserted into the fixed block 701, thereby locking the L-shaped block 703. This ensures the stability of the suspended object during movement, preventing it from easily shaking or falling off, thus guaranteeing the stability and accuracy of the hoisting process. The motor 602 drives the bidirectional threaded rod 601 to rotate. The rotation of the bidirectional threaded rod 601 facilitates the relative or opposite movement of the two moving blocks 603. The relative or opposite movement of the moving blocks 603 facilitates the lifting and lowering of the connecting block 9 and the hook 10 via the locking device 7 and the wire rope 8, quickly adjusting the height of the suspended object, saving time and improving work efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
