Technical Field
[0001] The utility model relates to the technical field of lifting and transporting equipment, in particular to a high-efficiency load balancing device for a vehicle-mounted crane winch mechanism. Background Art
[0002] A winch is a light and small lifting equipment that uses a drum to wrap a wire rope or chain to lift or pull heavy objects. It is also called a winch. The winch can lift vertically, horizontally or tiltedly pull heavy objects. When the existing truck-mounted crane winch is in use, the lifting rope will twist due to different positions when the winch is wound, causing the object hoisted by the hook to rotate in the air, resulting in instability when the load is lifted, which in turn affects the safety of the lifting. In view of the above problems, the inventor proposes an efficient load balancing device for a truck-mounted crane winch mechanism to solve the above problems. Utility Model Content

[0006] Preferably, the bottom surface of the guide cylinder is fixedly connected with a vertical rod, and the end of the vertical rod away from the guide cylinder is fixedly connected to the top surface of the movable block. The wire rope needs to pass through the tube mouth of the guide cylinder when it is retracted and released. When the wire rope is retracted and released, the electric cylinder is started, and the movable block drives the vertical rod to move under the action of the output shaft of the electric cylinder, thereby moving the guide cylinder. The moving direction of the guide cylinder must be the same as the direction of the retracting and releasing line of the wire rope, so that the wear between the wire rope and the guide cylinder can be reduced when releasing the line, and the wire rope can be evenly retracted on the retracting and releasing wheel of the winch body when retracting the line.

The top surface of the convex plate and one side of the shell are fixedly connected to a vertical plate, and the top surface of the vertical plate is fixedly connected to the concave seat.
[0008] Compared with the prior art, the beneficial effects of the utility model are:
[0009] 1. In the utility model, the balancing block and the concave seat are arranged on the same horizontal plane. When the wire rope moves in the concave seat through the balancing block, the wire rope from the balancing block to the concave seat can be kept in a straight state, thus avoiding twisting of the wire rope, thereby improving the stability when lifting the load. The balancing block can be adjusted up and down. Through the mutual cooperation of the threaded rod and the threaded barrel, and under the cooperation of the guide plate, the threaded barrel can drive the balancing block to rise and fall, so as to match the winding thickness of the wire rope on the winch body, thereby reducing the wear of the wire rope and the balancing block, and extending the service life of the wire rope;
[0010] 2. In the utility model, when the wire rope is being retracted and released, starting the electric cylinder can control the movement of the guide cylinder, and the moving direction of the guide cylinder is the same as the direction of the retracted and released line of the wire rope.
