Method for replacing lifting ropes of multi-rope frictional geared winch

A technology of hoisting ropes and friction wheels, which is applied to lifting equipment, transportation, and packaging in mines. It can solve problems such as high labor intensity for workers, falling objects in shafts, and long replacement operations, so as to improve the level of mechanized operations and reduce The effect of changing rope time and reducing labor intensity

Problems solved by technology

First, the labor intensity of the workers is high. All clamps must be manually tightened. The new steel wire rope enters the hoist shaft with manual assistance, and the old steel wire rope must be pulled out manually.
Second, all the personnel working on the upper and lower clamps need to work on the wellhead. If you are not careful, you will drop objects in the wellbore, which will easily lead to accidents.
Third, the replacement operation takes a long time, generally about 20 hours, which affects the normal production of the mine

Embodiment Construction

[0014] Depend on figure 1 As can be seen, the present invention comprises: two tension machines, block pulleys, sky wheel, hoisting rope, winch, two tractors, container I, container II. The hoisting ropes are arranged on the winch in order of No. 1, No. 2, No. 3, and No. 4. Lift the container I of the friction wheel winch to the wellhead and stop running. No. 1 and No. 3 of the four old hoisting ropes that connect the container I Untie and remove the ends of the two old hoisting ropes, and at the same time connect the removed ends of the old hoisting ropes with the pulleys of the two tractors, and pass the two new hoisting ropes around the pulley block through the two tension machines Join with container I. The specifications of the tensioner match the lifting capacity of the friction wheel winch, and the specifications of the tractor match the length of the hoisting rope. Start the friction wheel winch to lift the container II, and the rope take-up wheels of the two tractor...

Abstract

The invention discloses a method for replacing lifting ropes of a multi-rope frictional geared winch. A tensioner, a pulley block, a head sheave, the lifting ropes, the winch, a tractor, a container II and a container II are involved; and according to the characteristics of the multi-rope frictional geared winch, the ropes are replaced by effectively using the tensioner and the tractor, at least two ropes are always kept connected with the containers, the winch has enough traction to draw the containers in the rope replacement construction process, the lifting ropes keep enough intensity, themechanical operation level is improved, rope replacement time is reduced, the labor intensity of workers and high-attitude operation time at a wellhead are reduced, the aim of replacing the ropes safely is fulfilled and normal production is guaranteed.

Description

Technical field: [0001] The invention belongs to the technical field of replacement of hoisting ropes of friction wheel winches. Background technique: [0002] With the extension of mine mining depth, more and more multi-rope friction wheel winches are used for lifting and transportation. The multi-rope friction wheel winch has the characteristics of simple system and adaptability to different well depths. When working, the two ends of the hoisting wire rope are respectively connected with containers. The wire rope goes around the sky wheel and then winds on the winch drum. One of the two containers rises and the other descends. When one of them rises to the wellhead, the other descends to the well end. Because the steel wire rope used will rust, fatigue and other reasons, it must be replaced regularly. Article 403 of the "Coal Mine Safety Regulations" stipulates that the service life of the hoisting wire rope of the friction wheel winch shall not exceed two years at most...
