Description

Technical Field

[0001] The utility model belongs to the field of industrial lifting mechanical equipment, and in particular relates to a multifunctional overhead crane covering material wire rope protective cover. Background Art

[0002] In the electrolytic aluminum production, the multifunctional unit uses a wire rope assembly to realize the feeding of the material pipe. The material pipe is connected to the output end of the motor through the covering wire rope. The wire rope is wound on a drum connected to the motor. The motor is driven to lift and lower through forward and reverse rotation to realize the feeding action at the end of the wire rope. The light and small lifting equipment that lifts or pulls heavy objects with a wire rope wound on the drum can realize the functions of vertical lifting, horizontal or inclined dragging and pulling of heavy objects, which is extremely convenient for various production needs.

[0003] In daily use, the motor and drum of common wire rope assemblies are exposed outside without any covering baffles and are installed at high places, which poses a great safety hazard. A large amount of dust will rise between the grooves used for production, which can easily cause excessive oil sludge and poor lubrication of the wire rope. It is necessary to frequently disassemble and install the protective cover to maintain the winch and check the lubrication of the wire rope. In actual production, it is often seen that the staff will inspect and maintain the covering material platform without shutting down the motor and the wire rope is still running. At this time, it is easy to accidentally touch the covering material wire rope and cause people to be squeezed and injured. Therefore, it is very necessary to set up a shielding protective cover. By adding a protective cover, it can effectively prevent the staff from directly installing and repairing the wire rope part when the device is running, causing unnecessary safety hazards.

[0004] Some patents on wire rope assemblies are disclosed in the prior art, among which the invention patent with the announcement number CN108821151A discloses a winch reel drum, which includes a protective device, a motor, a support plate, a belt cover, a reel drum and a fixing frame, wherein the motor, the protective device, the belt cover and the fixing frame are all installed on the upper end of the support plate, the motor is arranged on the left part of the upper end surface of the support plate, the belt cover is arranged on the rear side of the motor, the reel drum is arranged on the right side of the motor, the fixing frame is arranged on the front end of the reel drum, the belt cover is arranged on the rear end of the reel drum, the protective device The protective device is installed on the upper end of the fixed frame, and the protective device includes a protective cover, a moving block, a slider, a lever, a spring, a transparent plate, a pressure plate and an observation hole. The protective cover is fixed on the upper end of the fixed frame, and the right end face of the protective cover is processed with an observation hole. The transparent plate is installed inside the observation hole. The pressure plate is set on the left side of the transparent plate. The spring is fixed on the left end of the pressure plate. The moving block is installed on the left end of the spring. The pressure plate and the moving block are connected by a spring. The slider is fixed on the upper and lower ends of the moving block respectively. The slider on the upper end of the moving block is welded with a lever, and the lever passes through the right end face of the protective cover. Although the problem of exposed steel wire being oxidized and rusted, which poses a certain safety hazard, there is still a problem that the packaging is not tight enough and the staff forcibly repairs the equipment without shutting down.
