Description

Technical Field

[0001] This utility model relates to the field of electric hoists, specifically a lubrication device for the wire rope of an electric hoist. Background Technology

[0002] Electric hoists are specialized lifting equipment installed on overhead cranes and gantry cranes. They are characterized by their small size, light weight, simple operation, and ease of use, and are commonly used in industrial and mining enterprises, warehouses, docks, and other similar locations. During operation, the wire rope of an electric hoist is typically exposed to the air. Since the working environment of electric hoists is often harsh, this can cause corrosion of the wire rope. The corrosion damage to the wire rope surface creates differences in oxygen affinity, causing one area of ​​the metal to act as the anode and another adjacent area as the cathode, forming numerous small batteries. Under the influence of these batteries, many circular corrosion pits form on the surface, gradually deepening until rust appears on the wire rope. This can eventually lead to the wire rope jamming or even seizing, affecting the operation of the electric hoist.

[0003] Currently, lubricating wire ropes requires workers to hold an oil drum and apply the lubricating oil to the wire rope using a brush. This method of lubricating wire ropes needs to be done separately when the electric hoist is not in operation, which is labor-intensive and affects the working efficiency of the electric hoist. Therefore, we propose a lubrication device for electric hoist wire ropes to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a lubrication device for the wire rope of an electric hoist, so as to solve the problems mentioned in the background art and overcome its technical defects.

[0006] Preferably, the bottom surface of the storage box is fixedly connected to a fixing frame, and the inner side wall of the fixing frame is fixedly inlaid with symmetrical bearings.

[0007] Preferably, the inner rings of both bearings are fixedly connected to rotating columns, and the ends of the two rotating columns that are close to each other are fixedly connected to limit guide wheels.

[0008] Preferably, a connecting block is fixedly connected to the bottom end of the wire rope body, and a hook is fixedly connected to the bottom end of the connecting block.

[0009] Preferably, an oil injection pipe is fixedly connected to the upper surface of the storage tank, and an oil injection valve is provided at the top end of the oil injection pipe.

[0010] Preferably, a positioning frame is fixedly connected to the front of the protective cover, the inner wall of the positioning frame is fixedly connected to the outer surface of the oil pump, four mounting holes are opened on the front of the mounting plate, a connecting wire is provided on the bottom surface of the electric hoist body, and a controller is fixedly connected to the bottom end of the connecting wire.

[0011] Compared with the prior art, the beneficial effects of this utility model include:

[0012] The combination of a fixed frame, rotating column, and bearings allows the limit guide wheel to rotate, which in turn limits the movement of the wire rope. A hook facilitates the lifting of objects, a protective cover protects the electric hoist body, a storage tank stores lubricating oil, and a pump and distributor pipe allow for oil extraction and distribution. A drip head allows for lubricating oil to drip out, and absorbent cotton blocks absorb the lubricating oil. A compression spring and absorbent cotton blocks clamp the wire rope, facilitating lubrication during operation, saving manpower, and preventing any impact on the electric hoist's efficiency.
