Steel wire rope greasy filth cleaning device

Abstract

The invention provides a steel wire rope greasy filth cleaning device, which comprises a greasy filth collecting bottom plate and is characterized in that a notch allowing a steel wire rope to pass is formed in the greasy filth collecting bottom plate, a left scraper and a right scraper which are opposite and are connected through a hinging shaft are respectively arranged at the two sides of the greasy filth collecting bottom plate, the upper ends of the left scraper and the right scraper are respectively provided with circular arc-shaped concave cutter openings, the two circular arc-shaped concave cutting edges are in butt joint for forming a greasy filth scraping circular cutter opening, a connecting plate is fixedly connected on the right scraper, the outer end of the connecting plate is connected with the right end of a clamping frame through a hinging shaft, one end of the clamping frame is connected with a handle, the clamping frame is in a fork shape, the middle part of the clamping frame is fixedly connected with a right clamping rod, and the left end of the clamping frame is assembled with a left clamping screw rod. The steel wire rope greasy filth cleaning device has the advantages that the cleaning is convenient and fast, the cleaning effect is good, and the work intensity is reduced.

Description

technical field [0001] The invention belongs to an auxiliary device of a mine hoist, in particular to an oil sludge cleaning device for a steel wire rope. Background technique [0002] The existing coal mine main shaft hoist is a multi-rope friction type, with a total of 4 main hoisting wire ropes, each with a length of 550m and a service life of 12 months. In order to reduce friction, the inside of the steel wire rope is lubricating oil. During the operation of the hoist, the steel wire rope is squeezed by force, and the internal oil gradually seeps out. In addition, the main shaft frequently lifts coal, resulting in a large amount of coal dust inside the shaft, which makes the steel wire rope Oil seepage on the surface sticks to coal dust and becomes oily sludge. If the elevator runs continuously for a long time, the sludge on the surface of the wire rope will accumulate more and more. In winter, due to the cold climate, the oil sludge is relatively hard, and more oil is...

AI Technical Summary

Problems solved by technology

Due to the tight arrangement of the pads, the extrusion force between the pads will gradually increase, resulting in damage to the contact surface between the pads and affecting the integrity of the pads

[0006] (4) During the process of lifting coal in the main shaft, if impurities such as coal particles or stone particles are mixed into the oil sludge of the steel wire rope, when the steel wire rope with oil sludge mixed with impurities passes through the drum, the surface of the drum pad will be squeezed into pits shape, causing damage to the pad

[0007] (5) The sludge is viscous, and it will be squeezed and stuck to the drum during the operation of the wire rope. When the winter is cold, the adhered sludge will be sticky and hard, making it impossible to clean it manually, and it can only be done by turning the rope groove.

In the process of turning the rope groove, a small amount of lining blocks will be cut off, resulting in an increase in the depth of the rope groove and a slight change in the rope difference of the wire rope, which will affect the lifting stability.

[0008] (6) Since the surface of the steel wire rope is covered with sludge, it is impossible to check the condition of the steel wire rope correctly, which will make it difficult to find hidden dangers such as corrosion and broken wires, which is especially unfavorable for safety improvement

[0009] At present, although the main shaft hoist is shut down for maintenance every day, the time for shutting down for maintenance is limited, the maintenance task is heavy, and it takes a long time to clean up the sludge, and some even cannot be cleaned manually, resulting in the inability to solve the problem of wire rope sludge cleaning in time, so it is urgently needed Provides a convenient and quick cleaning of steel wire rope oil sludge device
