Abstract
The invention relates to a mine hoisting device operation method and particularly relates to a method for preventing impacts produced when a mine hoist hoists containers. The method is characterized in that hoisting steel ropes of the hoist are subjected to releasing treatment. According to the method for preventing impacts produced when the mine hoist hoists the containers, the problem that the containers impact containers, well walls or cage guides due to stretch and twist of the steel ropes can be effectively solved, and the operation method is practical and effective.
Description
Technical field
Prevent the shock method that mine hoist lifting container occurs, relate to the method for operation of lifting device for mine.
Background technology
Mine hoisting is by the Lifting Convey work being arranged on well head, the apparatus in pit shaft and shaft bottom carries out, mine hoisting steel cable is the vitals of connecting container and gig, transferring power, its reliable use is the safety assurance of lifts personnel and material, and steel rope is the weakest link of security improvement, should pay attention to especially.The swing of the lifting container that the torsion of mine hoisting steel cable in pit shaft operational process causes, serious time the resonance that causes by between generation container and container, the collision of container and the borehole wall, container and derrick and cage guide, even cause container and personnel to fall the grave accident of well injures and deaths.
The complex component that mine hoisting steel cable be made up of many spirals unit, its stretching occurs with reversing simultaneously, and it is mutual etc. on the impact of linear deformation on the impact of torsional deflection and torsion to stretch.According to the hang of lifting heavy, hang weight and have the stretching of guiding when the weight that the two ends up and down of steel rope are all fixing, steel rope lower end hangs moves along rigid track, under the effect of pulling force, steel rope produces inner loose twist moment of torsion, but end produces a moment of face and loose twist equilibrium of torques by track below steel cable.If when hoisting depth is little, the deadweight of steel rope is very little compared with the weight of lifting heavy, the impact of steel rope deadweight can be ignored.Because lifting heavy can not rotate, we call pure extension above-described stretching.When adjustable height is large, although steel rope two ends are fixed, but under its Gravitative Loads, steel rope still produces strong torsion, the Lifting Convey work of mine hoist, just belong to this type of hang, under the cage (skip bucket) or counterweight effect of hoisting cable lower end, due to stretching and the torsion of hoisting cable, produce twist moment, cage (skip bucket) or counterweight are just to overcoming its opposition. and stop the container run in pit shaft to reverse, when the twisting resistance of hoisting cable exceedes the antagonistic force of cage guide to container, or twisting resistance in container operational process because of the container that produces under twisting resistance effect swing acquire a certain degree cause resonance time, case hits container will be caused, the borehole wall or cage guide etc.
Summary of the invention
Object of the present invention is exactly the deficiency existed for above-mentioned prior art, provides one can effectively solve because steel rope stretches and torsion, causes the shock method preventing mine hoist lifting container from occurring of the problem of case hits container, the borehole wall or cage guide.
The object of the invention is to be achieved through the following technical solutions.
Prevent the shock method that mine hoist lifting container occurs, it is characterized in that its method puts strength process to the hoisting cable of gig, the step of its treating process comprises:
(1) check the sliding sleeve wearing and tearing whether unstable wear phenomenon on inclined the same face of container, or container enters derrick and whether cage guide has abnormal sound; Find out the hoisting cable needing to put strength;
(2) container is placed on well head, selects to need the hoisting cable putting strength to carry out putting strength;
(3) will the steel rope putting strength be needed to unclamp from wire clips cover;
(4) be connected with the upper end of spinner by the free end of the steel rope eased out, and carry out mark with a fine rule rope, the lower end of spinner is fixed on container;
(5) M pressed by reel
2direction rotates, and one container is descending, another container is up, moves to pit shaft dark
time, M pressed by reel
1direction rotates;
(6) under the free rotary action of spinner, the loose twist torsion of steel rope is discharged;
(7) so repeatedly repeat 3 ~ 5 times (1)-(6) step, when seeing that the free end of steel rope rotates 5 ~ 8 circle from cord mark, the twisting resistance of steel rope just obtains release;
(8) container is put into well head, dismounting spinner, will the Steel wire rope lock of strength be discharged in wire clips cover, after adjusting rope to suppress, gig normal operation.
A kind of shock method preventing mine hoist lifting container from occurring of the present invention, can effectively solve because steel rope stretches and torsion, cause the problem of case hits container, the borehole wall or cage guide, method of operation is with practicability and effectiveness.
Accompanying drawing explanation
Fig. 1 is the structural representation of the mine hoist that a kind of shock method preventing mine hoist lifting container from occurring of the present invention relates to.
Detailed description of the invention
Composition graphs 1 to method of the present invention, be described further as.
Prevent the shock method that mine hoist lifting container occurs, its method puts strength process to the hoisting cable of gig, and the step of its treating process comprises:
1. check the sliding sleeve wearing and tearing whether unstable wear phenomenon on inclined the same face of container, or container enters derrick and whether cage guide has abnormal sound;
2. press figure below, container 2 is placed on well head, select the hoisting cable (reverse degree by container and select 1 or many ropes) needing to put strength to carry out putting strength;
3. need the steel rope 7 putting strength to unclamp from wire clips cover 3;
4. the free end of the steel rope 7 eased out is connected with the upper end of spinner 4, and carries out mark with a fine rule rope, and the lower end of spinner is fixing on vessel 2;
5. M pressed by reel
2direction rotates, and container 2 is descending, container 1 is up, moves to pit shaft dark
time, M pressed by reel
1direction rotates;
6., under the free rotary action of spinner, the loose twist torsion of steel rope 7 is discharged;
7. 3 ~ 5 bouts repeatedly like this, when seeing that the free end of steel rope 7 rotates 5 ~ 8 circle from cord mark, the twisting resistance of steel rope 7 just obtains release.
8. container 2 is put into well head, dismounting spinner, the steel rope 7 discharging strength is locked in wire clips cover, after adjusting rope to suppress, gig normal operation.
