Detailed Description

The present invention will be described in detail with reference to the following embodiments, wherein like or similar elements are designated by like reference numerals throughout the several views, and wherein the shape, thickness or height of the various elements may be expanded or reduced in practice. The examples are given solely for the purpose of illustration and are not intended to limit the scope of the utility model. Any obvious modifications or variations can be made to the present invention without departing from the spirit or scope of the present invention.

Example 1

Referring to fig. 1, in an embodiment of the present invention, an anti-jamming mechanism for preventing an imbalance in a lifting process includes a trolley 1, a fixing plate 7, a driving assembly and an anti-jamming assembly, where the fixing plate 7 is connected to a lifting plate 6 through the anti-jamming assembly, the lifting plate 6 is movably disposed in the trolley 1 through the driving assembly, the lifting plate 6 can be driven by the driving assembly to move in a vertical direction, the fixing plate 7 is provided with a conveying mechanism 8, an object can be conveyed by the conveying mechanism 8, and the lifting plate 6 can drive the conveying mechanism 8 to move when moving, so as to facilitate the transfer of the object, and the trolley 1 is convenient to move integrally; the anti-blocking component is arranged at two ends of the lifting plate 6, and the anti-blocking component is arranged to prevent the lifting plate 6 from being blocked due to unbalance of the two ends in the moving process, so that the anti-blocking lifting plate has good practicability.

Referring to fig. 2, the driving assembly includes a cylinder 2 disposed on the trolley 1, an output end of the cylinder 2 is connected to the telescopic rod 3, the cylinder 2 can drive the telescopic rod 3 to move in a vertical direction when working, and a movable pulley 4 is mounted at an end of the telescopic rod 3, that is, the telescopic rod 3 can drive the movable pulley 4 to move when moving; the driving assembly further comprises a belt 5, one end of the belt 5 is fixed on the trolley 1, the other end of the belt bypasses the movable pulley 4 and is fixedly connected with the lifting plate 6, and the movable pulley 4 can drive the lifting plate 6 to move in the vertical direction due to the fact that the length of the belt 5 is fixed when the movable pulley 4 moves.

Further, both ends of the lifting plate 6 are fixed with sliders 10, the sliders 10 are matched with a vertical guide rail 9 on the trolley 1 for use, when the lifting plate 6 moves, the sliders 10 can be driven to slide on the guide rail 9, so that the stability of the lifting plate 6 during moving is improved, and the safety of the lifting plate 6 during moving is improved.

Referring to fig. 3-6, the anti-jamming assembly includes two hinge shaft sleeves 11 disposed on the lifting plate 6, the number of the hinge shaft sleeves 11 is two, and the hinge shaft sleeves are respectively used in cooperation with the first hinge shaft 12 and the second hinge shaft 13, the end of the fixing plate 7 close to the first hinge shaft 12 is inserted into the groove of the first hinge shaft 12 to form a moving pair, and the end close to the second hinge shaft 13 is inserted into the groove of the second hinge shaft 13 and is locked by a bolt, so that even if an error occurs in the heights of the two ends of the fixing plate 7 during the moving process, the fixing plate 7 is not jammed due to tilting, and the moving capability of the fixing plate 7 is improved, thereby having very good practicability.
