[0025] When the prefabricated parts need to be disassembled, the prefabricated parts are placed on the corresponding processing table (belonging to the existing technology), the lifting plate 2 moves down, drives the connecting plate 6 to return, and cooperates with the use of the clamping claws 5 to separate the support plate 3 from the prefabricated parts, so as to loosen the prefabricated parts and achieve the purpose of unloading. The operation is simple and convenient, the transportation efficiency is improved, and the traditional manual handling operation is replaced, saving time and labor.

[0026] The clamping mechanism includes a plurality of support plates 3, a plurality of support seats 4, a plurality of clamping claws 5, a plurality of connecting plates 6, and a plurality of fixing plates 7. Three support plates 3 may be provided, and corresponding support seats 4, clamping claws 5, connecting plates 6, and fixing plates 7 are also provided in three, and adjacent angles are equal. The support seat 4 is fixed to the top of the fixing plate 1, and the support seat 4 is used for the clamping claws 5 to support. The two ends of the clamping claws 5 are connected to the support plates 3 and the connecting plates 6, the end of the connecting plate 6 is connected to the fixing plate 7, and the end of the fixing plate 7 is fixedly connected to the lifting plate 2.

[0027] The clamping jaws 5 are axially connected to the support base 4, and the angles between adjacent support bases 4 are equal. The support base 4 is equivalent to the fulcrum of the lever, and the two ends of the clamping jaws 5 rotate around the fulcrum. When point b moves downward, the corresponding support plate 3 moves upward.

[0028] The end of the clamping jaw 5 is axially connected to one end of the connecting plate 6 , and the other end of the connecting plate 6 is axially connected to the fixing plate 7 .

[0029] A plurality of guide posts 13 are connected to the top of the fixed plate 1, and a guide sleeve 8 matching the guide posts 13 is connected to the lifting plate 2. Two guide posts 13 may be provided and are relatively distributed. When the lifting plate 2 is lifted or lowered, the guide sleeve 8 slides on the corresponding guide post 13, which can improve the lifting stability of the lifting plate 2.

When unloading the prefabricated parts, the downward movement of the lifting plate 2 can synchronously drive the downward movement of the hanging plate 10 and the suspension rod 12. The suspension rod 12 slides on the guide surface 14 until it is separated from the guide surface 14. Due to the gravity factor, the suspension rod 12 rotates and moves vertically downward to correspond to the corresponding hanging groove 16. At this time, the clamping mechanism is in an open state, which is convenient for automatic unloading of the prefabricated parts and has strong practicality. In the unloaded state, the suspension rod 12 is connected to the hanging groove 16, so that the clamping mechanism is in an open state, and the corresponding support plate 3 remains in the same position, which is convenient for the subsequent clamping of the prefabricated parts.

[0034] Working principle: When clamping the prefabricated part, the clamping mechanism is in an open state, and the suspension rod 12 is connected to the hanging groove 16. Then the lifting plate 2 moves down, driving the fixed plate 1 to move down. The fixed plate 1 is connected to the top of the prefabricated part, and the position of the fixed plate 1 remains unchanged. The lifting plate 2 continues to move down for a certain distance, and synchronously drives the suspension rod 12 to move down, so that the suspension rod 12 is separated from the hanging groove 16, and then the suspension rod 12 is moved away from the connecting seat 11. Then the lifting mechanism is used to drive the lifting plate 2 to move up, and synchronously drives the suspension rod 12 to move up and away from the connecting seat 11. The lifting plate 2 applies a pulling force to the connecting plate 6, and the connecting plate 6 drives the end of the clamping claw 5 to tilt up, so that the support plate 3 clamps the prefabricated part, improves the stability of the prefabricated part, and facilitates the transportation operation. When the prefabricated parts need to be unloaded, the prefabricated parts are placed on the corresponding processing table, the lifting plate 2 moves down, and the connecting plate 6 is driven to return, that is, one end of the clamping claw 5 moves down, and the support plate 3 at the other end moves up, so that the support plate 3 is separated from the prefabricated parts, and the prefabricated parts are loosened to achieve the purpose of unloading, and the operation is simple and convenient. At the same time, during the downward movement of the lifting plate 2, the suspension rod 12 slides on the guide surface 14 until it is separated from the guide surface 14. Due to the gravity factor, the suspension rod 12 rotates and moves vertically downward to correspond to the corresponding hanging groove 16. During lifting, the clamping mechanism is in an open state, and the corresponding support plate 3 remains in position, which is convenient for the subsequent clamping of the prefabricated parts.
