Description

Coal mine shaft lining cage contracting rope method
Technical field
The present invention relates to the installation maintenance technologies of coal mine shaft lining cage.
Background technology
As coal adopts deep increase, the raising of mine yield is promoted using vertical cage as mine main lift side Formula is more and more common.The promotion of vertical cage at least four steel wire ropes, every steel wire rope pass through hydraulic cylinder for adjusting rope and winding cage Connection, the stress that hydraulic cylinder for adjusting rope is used to adjust steel wire rope are consistent.The increasing loaded after winding cage is used for a long time and in cage Add, steel wire rope necessarily occurs extending phenomenon.The elongation of steel wire rope can cause cage to stop tank position and cage chair absolute altitude in upper and lower well head It is inconsistent.When rope stretch amount is little, by asking tank beam to carry out horizontal retort to cage;If rope stretch amount is larger, It then must just can guarantee that cage is parked in well head plane by the rope that contracts, ensure to go into the well on normal mine car and personnel.So each The time that the moon must all be extracted out 1-2 days carries out contracting rope.
Existing vertical contracting rope walking or dancing art is to coordinate two sets of big boards and auxiliary tool with 4 I-steel and multiple chain blocks It is several to complete entire contracting rope process, and need that 20 people or so professional team is engaged to construct, entire contracting rope process is extremely Need 20 hours that could complete less, personnel need repeatedly to climb up and climb down in head sheave, well head, underground, overlapping activity, once occur Unbalance stress is easy to cause cage inclination, jeopardizes construction personnel's safety, causes that mine idle time is long, influence the production of mine Amount.
Therefore studying a kind of coal mine shaft lining cage, safely and fast contracting rope walking or dancing art is necessary.
Invention content
The purpose of the present invention is to propose to a kind of coal mine shaft lining cage contracting rope methods.
A kind of coal mine shaft lining cage contracting rope method, which is characterized in that steps are as follows:
The first step, survey calculation contracting rope amount well;Elevator is started, the cage of emptying is parked in the well head operated suitable for personnel Position, the position on cage hoisting steel wire rope wedge rope_ring with big board and coordinate screw that all steel wire ropes is whole It blocks locked, and is again blocked the fag end of every steel wire rope with rope clip, all steel wire ropes become a stress entirety at this time;
Second step, then the hydraulic cylinder for adjusting rope of wherein steel cable is subjected to oiling and is suppressed, so that hydraulic cylinder for adjusting rope is extended, oil cylinder is stretched Long amount is equal to contracting rope amount, and oil cylinder elongation makes the steel wire rope looseness get off no longer stress, closing hydraulic cylinder for adjusting rope valve, by other steel wires Rope undertakes original pulling force;
Third walks, and unclamps the rope clip not stressed on cable wire end, the steel wire that do not stress is fixed with chain block chain Rope fag end, chain block is hung on stress point, is unclamped the fixture block of former wedge rope_ring, chain block is pulled, in wedge rope_ring The steel wire rope that do not stress for extracting relaxation out, tightens the fixture block of wedge rope_ring, and it is extra to be sliced off according to the contracting rope amount calculated a section tool The cable wire end that do not stress, fixation do not stress the wedge rope_ring of steel wire rope, then adjusts hydraulic cylinder for adjusting rope and make the steel wire that do not stress Stress of restricting tensioning, and oil cylinder valve is closed, complete the contracting rope process of wherein steel cable;
Then 4th step carries out contracting rope process to remaining steel wire rope successively with third step same method;
5th step opens the oil cylinder valve of all steel wire rope hydraulic cylinder for adjusting rope after the completion of contracting is restricted, and so that hydraulic cylinder for adjusting rope is retracted and ensures The uniform tension in order of all steel wire ropes;Remove big board and rope clip;Stop tank position according still further to the upper and lower cage of conventional method inspection It sets, again by the stroke of adjustment hydraulic cylinder for adjusting rope, makes to stop tank position to meet prescribed requirement.
The positive effect of the present invention:
1, the present invention need to only be can be completed using chain block, 1 set of big board and some common tools, few using tool, Reduce the consumption of materials and supplies.
2, the present invention need not engage professional team to construct, and 5 maintenance personals of Zhi Xu our units can be completed, 15 people or so are reduced than original method, reduce cost of labor.
3, the present invention only needs or so 4 hours can be completed, than the time that original method shortens 75%, idle time It is short, improve the hoisting power of mine.
4, the present invention only needs personnel to be carried out in the above position of well head, climbs down overlapping activity without repeatedly climbing up, disposably It completes.Cage is in band rope suspension status always, and cage will not tilt, entirely without danger of falling, construction personnel's safety.
Description of the drawings
Fig. 1 is the front view of the embodiment of the present invention;
Fig. 2 is the side view of the embodiment of the present invention.
In figure, 1- cages, 2- hydraulic cylinder for adjusting rope, 3- rope clips, 4- wedge rope_rings, the big boards of 5-, 6- steel wire ropes.
Specific implementation mode
Technical scheme of the present invention is further appreciated that below in conjunction with the accompanying drawings.
Coal mine shaft lining cage contracting rope method as depicted in figs. 1 and 2, includes the following steps:
The first step, survey calculation contracting rope amount well;Elevator is started, the cage 1 of emptying is parked in the well operated suitable for personnel Mouth position, the appropriate location on cage hoisting steel wire rope wedge rope_ring 4 with big board 5 and coordinates screw by all steel Cord 6 is all blocked locked, and is again blocked the fag end of every steel wire rope 6 with rope clip 3, all steel wire ropes 6 become at this time One stress entirety;
Second step, then the hydraulic cylinder for adjusting rope 2 of wherein steel cable 6 is subjected to oiling and is suppressed, so that hydraulic cylinder for adjusting rope 2 is extended, oil Cylinder elongation is equal to contracting rope amount, and the elongation of hydraulic cylinder for adjusting rope 2 makes the steel wire rope 6 relax no longer stress, closing 2 valve of hydraulic cylinder for adjusting rope Door, original pulling force is undertaken by other steel wire ropes;
Third walks, and unclamps the rope clip 3 not stressed on 6 fag end of steel wire rope, the steel that do not stress is fixed with chain block chain 6 fag end of cord, chain block is hung on stress point, is unclamped the fixture block of former wedge rope_ring 4, is pulled chain block, is restricted in wedge shape The steel wire rope of extraction relaxation, tightens the fixture block of wedge rope_ring 4 in ring 4, according to the contracting rope amount calculated with cut have slice off not by The extra fag end of power steel wire rope 6, the wedge rope_ring 4 of the fixation steel wire rope 6 that do not stress, then adjust hydraulic cylinder for adjusting rope 2 make not by 6 stress of power steel wire rope is tensioned, and closes 2 valve of hydraulic cylinder for adjusting rope, completes the contracting rope process of wherein steel cable;
Then 4th step carries out contracting rope process to remaining steel wire rope successively with third step same method;
5th step opens the oil cylinder valve of all steel wire rope hydraulic cylinder for adjusting rope 2 after the completion of contracting is restricted, and so that hydraulic cylinder for adjusting rope 2 is retracted and protects Demonstrate,prove the uniform tension in order of all steel wire ropes 6;Remove big board 5 and rope clip 3;According still further to stopping for the upper and lower cage of conventional method inspection 1 Tank position makes to stop tank position to meet prescribed requirement again by the stroke of adjustment hydraulic cylinder for adjusting rope 2.
