Abstract
Description
Technical Field
[0001] The utility model belongs to the field of electric hoists and relates to an electric hoist, in particular to an automatic lubricating electric hoist. Background Art
[0002] Electric hoist is a special lifting equipment installed on overhead crane and gantry crane. Electric hoist has the characteristics of small size, light weight, simple operation and easy use. It is used in industrial and mining enterprises, warehouses, docks and other places.
[0003] The electric hoist can reel in and release the wire rope, causing the movable pulley and hook to rise and fall, and is responsible for the longitudinal movement of the workpiece. The wire rope bears the entire weight of the workpiece. It is usually necessary to maintain the wire rope regularly to extend its service life. Maintenance means that the staff stand on the overhead crane and manually apply lubricating oil to the wire rope to reduce the friction of the wire rope, which not only increases the risk of falling during high-altitude operations, but also increases the labor intensity of the staff. Summary of the invention
[0004] The utility model aims to provide an automatic lubricating electric hoist with a long service life in view of the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved through the following technical solutions: an automatic lubricating electric hoist, comprising a wire rope, an electric hoist and a walking trolley for driving the electric hoist to move, characterized in that one end of the wire rope is connected to the electric hoist, the other end of the wire rope is connected to a roller mechanism, the roller mechanism consists of a roller body, a roller shaft and a roller combination, an oil reservoir is provided inside the roller, a groove matching the wire rope is provided on the roller, a plurality of oil outlet holes connected to the oil reservoir are provided on the roller and relative to the groove, a plurality of balls for reducing friction are provided in the oil reservoir and relative to the oil outlet holes, an oil injection pipe connected to the oil reservoir is provided on the roller, a plug is provided on the oil injection pipe, and a lubrication pipe 1 and a lubrication pipe 2 connected to the oil reservoir are respectively provided on both sides of the roller.
[0006] In the above-mentioned automatic lubrication electric hoist, a connecting portion is provided at the lower end of the roller body, and a hook is provided on the connecting portion.
[0007] In the above-mentioned automatic lubrication electric hoist, a bearing is arranged between the roller and the roller body.
[0008] Compared with the prior art, the utility model provides an oil storage tank and an oil outlet hole on the roller, and a ball is provided at the oil outlet hole. When the roller and the wire rope are in contact, rolling friction occurs. Compared with the previous sliding friction, the friction force on the wire rope is greatly reduced. When the ball rolls, the lubricant in the oil outlet layer will be driven to automatically lubricate the wire rope. The lubricant flowing out of the lubrication pipeline 1 and the lubrication pipeline 2 can fully lubricate the bearing and reduce the wear of the bearing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0014] like Figure 1As shown, the automatic lubrication electric hoist comprises a wire rope 1, an electric hoist 2 and a walking trolley 3 for driving the electric hoist 2 to move. One end of the wire rope 1 is connected to the electric hoist 2, and the other end of the wire rope 1 is connected to a roller mechanism 4. The roller mechanism 4 is composed of a roller body 5, a roller shaft 6 and a roller 7. An oil reservoir 8 is provided inside the roller 7. A groove 9 matching the wire rope 1 is provided on the roller 7. A plurality of oil outlet holes 10 connected to the oil reservoir 8 are provided on the roller 7 relative to the groove 9. A plurality of balls 11 for reducing friction are provided in the oil reservoir 8 and relative to the oil outlet holes 10. An oil injection pipeline 12 connected to the oil reservoir 8 is opened, and a plug 13 is arranged on the oil injection pipeline 12. Lubrication pipeline 14 and lubrication pipeline 2 15 connected to the oil reservoir 8 are respectively opened on both sides of the roller 7. The ball 11 causes rolling friction when the roller 7 and the wire rope 1 are in contact, which greatly reduces the friction force on the wire rope 1 compared with the previous sliding friction. When the ball 11 rolls, it will drive the lubricant in the oil layer to automatically lubricate the wire rope 1. The lubricant flowing out of the lubrication pipeline 14 and the lubrication pipeline 2 15 can fully lubricate the bearing 18 and reduce the wear of the bearing 18.
[0015] In further detail, a connecting portion 16 is disposed at the lower end of the roller body 5 , and a hook 17 is disposed on the connecting portion 16 .
[0016] In further detail, a bearing 18 is provided between the roller 7 and the roller body 5 .
[0017] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0018] Although this article uses more terms such as wire rope 1, electric hoist 2, walking trolley 3, roller mechanism 4, roller body 5, roller shaft 6, roller 7, oil reservoir 8, groove 9, oil outlet 10, ball 11, oil injection pipeline 12, plug 13, lubrication pipeline 1 14, lubrication pipeline 2 15, connecting part 16, hook 17, bearing 18, etc., it does not exclude the possibility of using other terms. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
