The movable hanging assembly is lowered, and then the hanging assembly is pulled up to reset; a locking mechanism 4 is arranged below the winding and unwinding assembly, and the locking mechanism 4 comprises a limiting cylinder 41, a limiting connecting piece and a locking piece, the limiting cylinder 41 is fixedly installed below the winding and unwinding assembly, the limiting connecting piece is connected and installed between the hanging rope 34 and the hanging assembly, the limiting connecting piece can be slidably clamped in the inside of the limiting cylinder 41 when the hanging rope 34 is in the winding state, and at the same time, the locking piece locks and fixes the limiting cylinder 41 and the limiting connecting piece, and the locking piece can release the lock of the limiting connecting piece when the hanging rope 34 is unwinding;

[0042] Specifically, when the hoisting and conveying equipment is practical, the circulating conveying mechanism 2 drives the multiple hoisting mechanisms 3 thereon to move in a circulating conveying manner. When the hoisting mechanism 3 moves to the hoisting position, the reeling and unreeling assembly unreel the hoisting rope 34, and at the same time, the locking member releases the lock on the limit connecting member, so that the limit connecting member and the hanging member are lowered along with the unreeling of the hoisting rope 34, so as to lower the height of the hanging member, and then the object to be conveyed is hung on the hanging member; then the reeling and unreeling assembly reel in the hoisting rope 34, so that the hoisting rope 34 pulls the limit connecting member, the hanging member and the hanging object upward synchronously, until the limit connecting member slides and is clamped in the inside of the limit cylinder 41, and at the same time, the locking member locks and fixes the limit cylinder 41 and the limit connecting member; finally, the circulating conveying mechanism 2 drives the hoisting mechanism 3 and the hanging object to be conveyed;

At the same time, the limit locking block 413 abuts against the bottom surface of the limit boss 49, so that the limit locking block 413 replaces the lifting rope 34 to support the limit boss 49, the hanger 32 and the objects being hoisted and conveyed, preventing the lifting rope 34 from breaking and being damaged due to long-term load-bearing; when the hanging box 31 moves to the hoisting position and the lifting rope 34 begins to unwind, the limit cylinder 41 passes through The connecting plate 46 drives the wedge block 47 to move closer to the guide bar 44.

The winding gear is fixedly installed on the end of the winding roller. The intermediate gear and the winding transmission gear are both rotatably installed on the inner wall of the hanging box, and the winding gear, the intermediate gear and the winding transmission gear are meshed and transmitted in sequence. The winding transmission rack is fixedly installed on the inner side of the bottom surface of the track frame and is located at the top of the moving track of the winding transmission gear, and the winding transmission rack and the unwinding transmission rack are staggered left and right.

6. The hoisting and conveying equipment according to claim 1, characterized in that: The hanging assembly comprises a hanger, and hooks are fixedly installed at both ends of the hanger.

7. The hoisting and conveying equipment according to claim 1, characterized in that: The limiting connecting member comprises a limiting shaft, the limiting shaft is fixedly mounted on the top surface of the hanging assembly, a connecting shaft is fixedly mounted on the top end of the limiting shaft, and a limiting boss is fixedly mounted on the top end of the connecting shaft.

8. The hoisting and conveying equipment according to claim 3, characterized in that: The locking piece includes a sliding groove and an unlocking unit. The sliding groove is opened on the inner wall of the lower end of the limiting cylinder. A limiting locking block extending to the inside of the limiting cylinder is slidably installed inside the sliding groove. A connecting rod is fixedly installed at one end of the limiting locking block.
