Description
Technical Field
[0001] The utility model relates to the technical field of hoist wire rope fixing, in particular to a movable fixing structure for hoist wire ropes. Background Technique
[0002] The main structural principle of a wire rope hoist is to wind and release the wire rope around the winch drum, and realize the lifting and lowering movement of the goods through the hook. The basic structure of the wire rope hoist includes a lifting platform, a winch, a wire rope, and a hook. One end of the wire rope is fixed and wound around the winch drum, and the other end bypasses the hook and is fixed on the lifting platform. By rotating the winch drum forward and backward, the wire rope can be wound or released, thereby realizing the lifting and lowering movement of the goods.
[0003] For example, the Chinese authorized patent with the publication number CN214359682U (Hoist for Maintaining Wire Ropes of Coal Mine Cage): It includes a base for fixedly connecting with a wedge connection device. A frame is fixedly connected to the base, and one or more sets of pinch rollers are rotatably connected to the frame. The axial direction of the pinch rollers is horizontal. The pinch rollers are driven by a motor, and the motor is connected to a power supply and a controller. When this device is in use, workers first lift the cage to near the highest position, fix the base to the wedge connection device, then pass the wire rope through the two sets of pinch rollers, and after starting the motor, the pinch rollers can be driven to lift the excess wire rope. It only takes less than one hour to complete the work.
[0004] However, both ends of the wire ropes of existing wire rope hoists are fixed. During the continuous winding, releasing, and stretching processes, it is easy to cause internal tension in the wire ropes, resulting in kinking, which in turn affects the strength and service life of the wire ropes, and even leads to wire breakage, with low safety. Therefore, it does not meet the existing requirements. For this reason, we propose a movable fixing structure for hoist wire ropes. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present utility model are:
[0014] 1. The utility model realizes the movability of the connection component by arranging a fixed base above the connection component. The fixed base is welded to the hoist fixing frame, and the connection component is not welded to the hoist fixing frame. Compared with the existing connection component directly welded to the hoist fixing frame, one end of the bolt passes through the through hole of the fixed base and is inserted into the installation hole, and is fixed to the welding plate by welding, realizing the connection between the fixed base and the connection component. Through the bolt, the connection component can rotate, that is, the steel wire rope can move. The movable connected steel wire rope can effectively release various stresses generated during the winding and releasing processes of the steel wire rope, prevent the steel wire rope from knotting and the steel wire from breaking, is beneficial to eliminating potential safety hazards, and prolongs the service life of the steel wire rope. It solves the problem that both ends of the steel wire rope of the existing steel wire rope hoist are fixed, and it is easy to cause tension inside the steel wire rope during continuous winding, releasing and stretching, resulting in kinking, which in turn affects the strength and service life of the steel wire rope, and even causes the steel wire to break, with low safety.
[0015] 2. By arranging limiting grooves on both the front and back surfaces of the connection seat, the force-bearing frame is inserted along the limiting grooves, and both ends of the force-bearing frame are located in the limiting grooves. When the steel wire rope is stressed, it can ensure that the connection between the force-bearing frame and the connection seat does not break and separate. One end of the first fastener and the second fastener passes through the protection plate and is threadedly fixed to the first connection hole and the second connection hole respectively, to limit and fix the force-bearing frame to prevent it from falling, and it is also convenient to disassemble and replace the force-bearing frame. Compared with the existing welding fixation, the force-bearing frame can be independently replaced. After being worn by the steel wire rope, the whole connection component does not need to be replaced, reducing the replacement cost. BRIEF DESCRIPTION OF THE DRAWINGS
