[0026] In one embodiment of the present invention, Figures 1 to 7 As shown, an anti-fall servo screw hoist is provided, comprising a cabinet 1 and a lifting mechanism 2 arranged in the cabinet 1, the cabinet panels on the left and right sides of the cabinet 1 are provided with connecting windows 11, and a driving motor 12 is provided at the top of the cabinet 1, the lifting mechanism 2 comprises a lifting screw 21, a guide rail 22 and a scissor-type connecting rod 23, the guide rail 22 is symmetrically arranged on the left and right sides of the lifting screw 21, the driving motor 12 is used to drive the lifting screw 21, the lifting screw 21 is threadedly connected with a nut 3, and the nut 3 extends with sliders 30 to the left and right sides, the two slides 31 are slidably connected to the guide rails 22, and the rear side of the nut 3 is slidably connected to a mounting plate 32, and a plug block 33 is provided between the mounting plate 32 and the nut 3 to achieve position fixing, the top surface of the mounting plate 32 is provided with a mounting surface, and the bottom of the scissor-type connecting rod 23 is provided with a driving part 231, and the top is detachably connected to the bottom surface of the mounting plate 32, and the driving part 231 is installed at the bottom of the cabinet 1.

[0027] Furthermore, the left and right cabinet panels of the cabinet 1 are hinged to the cabinet body of the cabinet 1. Specifically, under normal circumstances, the mounting plate 32 can be fixed to the nut 3 directly through the connecting window 11. By setting the hinge between the cabinet panel and the cabinet body, the cabinet panel can be opened when fixing the mounting plate 32, so that the staff can have more space to display and the operation is more convenient for the staff.

[0028] Furthermore, a slide groove 34 is provided on the rear side of the nut 3, with an opening to the left or right. Reinforcing ribs 341 are provided on the top of the slide groove 34. Sliders 31 are provided on the front side of the mounting plate 32, with a groove 311 provided on the top surface of the slide 31 for sliding connection with the reinforcing rib 341. The insert 33 is slidably engaged between the nut 3 and the mounting plate 32. A stop plate 342 is provided on the side of the slide groove 34 away from the opening, and the slide 31 has a clearance gap with the stop plate 342. Specifically, when fixing the mounting plate 32, the mounting plate 32 is inserted from the opening of the slide groove 34, and finally the slide 31 is completely inserted into the slide groove 34. At this time, the reinforcing rib 341 is inserted into the groove body 311, so that the movement between the mounting plate 32 and the nut 3 in the front-to-back direction is locked, and then the insert block 33 is inserted between the mounting plate 32 and the nut 3, so that the movement between the mounting plate 32 and the nut 3 in the left-to-right direction is locked, thereby achieving the fixation between the mounting plate 32 and the nut 3.

[0029] Furthermore, a hinge 331 is provided at the top of the insert block 33 for achieving a hinged connection between the insert block 33 and the nut 3. The insert block 33 is provided with a slot 332, the front side of which engages with the nut 3, and the rear side of which engages with the mounting plate 32. The bottoms of both the mounting plate 32 and the nut 3 are provided with a latching groove 35, which communicates with each other. An elastic block 333 is provided on the inner bottom surface of the slot 332, which engages with the two latching grooves 35. Specifically, to secure the mounting plate 32, the mounting plate 32 is inserted through the opening of the slide groove 34, and the slide 31 is finally fully inserted into the slide groove 34. At this point, the reinforcing rib 341 is inserted into the groove body 311. The insert block 33 is then rotated via the hinge 331, so that the slot 332 is inserted between the mounting plate 32 and the nut 3, and the elastic block 333 is elastically inserted into the latching groove 35, thereby better securing the mounting plate 32 and the nut 3.

[0030] Furthermore, the mounting plate 32 is provided with mounting grooves 321 on both sides, and the top of the scissor link 23 is rotatably connected to two fixing blocks 232, which are respectively used to engage with the two mounting grooves 321. Specifically, after the top surface of the scissor link 23 abuts the mounting plate 32, the staff rotates the fixing blocks 232 on both sides until they engage with the mounting grooves 321, thereby better fixing the position between the mounting plate 32 and the scissor link 23.

[0031] Working principle: Various transport mechanisms for transport lines, such as steering belts and cargo forks of transport lines, can be installed through the mounting surface of the top surface of the mounting plate 32, and then the cargo transfer between multiple conveyor belts with different heights and different transport directions can be realized through the lifting effect of the lifting mechanism 2. Therefore, multiple mounting plates 32 with different transport mechanisms installed can be prepared for backup before use, and a scissor-type connecting rod 23 can be set to realize the auxiliary support effect of the mounting plate 32 to improve the stability of the mounting plate 32; when using, find the mounting plate 32 with the corresponding function and install it on the nut 3 through the connecting window 11, and insert the block 3 through the plug 3 is fixed, at this time, the bottom of the mounting plate 32 abuts against the bottom of the scissor-type connecting rod 23, and the driving motor 12 drives the screw rod to move the nut 3 up and down, and at the same time drives the mounting plate 32 up and down, and the scissor-type connecting rod 23 also extends or contracts with the height of the nut 3 at the same time, so as to keep the top of the scissor-type connecting rod 23 always supporting the bottom surface of the mounting plate 32, so as to achieve better stability of the mounting plate 32. During the cargo exchange action, the transportation mechanism on the mounting plate 32 transports the cargo out through the connecting window 11. Since the connecting windows 11 are provided on the left and right sides of the cabinet 1, cargo transportation in more directions can be achieved.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
