All hoisting ropes are replaced by repeatedly using the method. According to the device disclosed by the utility model, the labor force is saved, the safety is improved and the work efficiency is increased.

Description

Change the device of mine hoisting rope

Technical field

The utility model relates to a kind of replacing technology of mine hoisting rope, belongs to the mine hoisting technical field.

Background technology

At present, much more more and more friction winding obtains using as the important form of vertical shaft hoisting.Safe and reliable for guaranteeing friction winding, changing hoisting rope is the important process that guarantees to promote safety.Mostly conventional method of replacing rope is that four or six roots of sensation rope change simultaneously, and well head, shaft bottom all need personnel to work, so that it is more to change in the rope process potential safety hazard; Conventional method of replacing rope is received old hoisting rope and put new hoisting rope all is that substep carries out, and most work all rely on and manually finish, so that change the rope time expand, changes rope efficient lower.

The utility model content

In order to overcome above-mentioned the deficiencies in the prior art part, the utility model provides a kind of device of changing the mine hoisting rope, uses this device to receive old hoisting rope and put new hoisting rope synchronized operation changing when rope, all operates at well head, increase the safety of changing rope work, increase work efficiency.

The utility model is achieved by the following technical solution:

A kind of device of changing the mine hoisting rope, it comprises mainly by upper head sheave, gig, lower head sheave, hoisting rope, the bont that lifting container I and lifting container II form, be connected with tail rope between the tail end of lifting container I and lifting container II, it is characterized in that: the well head track adjusting wheel is equipped with in the position near described lifting container I on the well head of mine, the rear portion of well head track adjusting wheel is equipped with changes the rope car, changing rope car rear portion is equipped with the rope closing winch and puts the rope winch, hoisting rope in described lifting container I one side has rope locking machine, on the hoisting rope of described lifting container II one side adjusting rope device is arranged.

The beneficial effects of the utility model are: adopted above-mentioned method of replacing rope and device, change and remain in the rope process that at least two hoisting ropes do not break from elevator system, and all changing rope work all finishes at wellhead ground, by large-scale, multiple cooperation of changing rope equipment, newly, old hoisting rope exchanges synchronously, saved manpower, shortened and changed the rope time, greatly increase the safety of changing rope work, improved the work efficiency that changes rope.

Among the figure, 1, gig; 2, lower head sheave; 3, upper head sheave; 4, new hoisting rope; 5, well head track adjusting wheel; 6, change the rope car; 7, rope closing winch; 8, put the rope winch; 9, rope locking machine; 10, old hoisting rope; 11, lifting container I; 11 ', lifting container II; 12, tail rope; 13, adjusting rope device; 14, well head; 15, shaft bottom.

The specific embodiment

Below in conjunction with embodiment the utility model is further specified.

Such as Fig. 1, Fig. 2, a kind of device of changing the mine hoisting rope shown in Figure 3, it comprises mainly by upper head sheave 3, gig 1, lower head sheave 2, hoisting rope, the bont that lifting container I 11 and lifting container II 11 ' form, be connected with tail rope 12 between the tail end of lifting container I 11 and lifting container II 11 ', it is characterized in that: well head track adjusting wheel 5 is equipped with in the position near described lifting container I 11 on the well head 14 of mine, the rear portion of well head track adjusting wheel 5 is equipped with changes rope car 6, changing rope car 6 rear portions is equipped with rope closing winch 7 and puts rope winch 8, hoisting rope in described lifting container I 11 1 sides has rope locking machine 9, on the hoisting rope of described lifting container II 11 ' one side adjusting rope device 13 is arranged.

The utility model is changed the method for mine hoisting rope during use, may further comprise the steps:

Step 1: install rope closing winch 7, put rope winch 8, change rope car 6, well head track adjusting wheel 5, adjusting rope device 13 and rope locking machine 9 etc. and change rope equipment, to be parked in 15 places, shaft bottom near the lifting container I 11 of changing rope car 6 one sides, the lifting container II 11 ' of opposite side is parked in well head 14 places;

Step 2: with rope locking machine 9 hoisting ropes 10 that chucking is had been friends in the past, mention described lifting container II 11 ' in described lifting container II 11 ' one side with adjusting rope device 13 in described lifting container I 11 1 sides, old hoisting rope 10 is relaxed;

Step 3: release two new hoisting ropes 4 and pass and change rope car 6 from putting rope winch 8, and through after the well head track adjusting wheel 5, the arbitrary point of connection A place of described two new hoisting ropes 4 above rope locking machine 9 is connected with two old hoisting ropes 10;

Step 4: between described point of connection A and rope locking machine 9, select a place, hoisting rope 10 old with two that described new hoisting rope 4 is connected disconnected, the epimere of two old hoisting ropes 10 after the disconnection drew head sheave 3, gig 1 and lower head sheave 2 to new hoisting rope 4, new hoisting rope 4 is connected with described lifting container II 11 ', and the epimere of two old hoisting ropes 10 is removed;

Step 5: the hypomere end of two old hoisting ropes 10 after the disconnection through well head track adjusting wheel 5, pass and change rope car 6, be connected to rope closing winch 7;

Step 6: withdraw from described adjusting rope device 13 and rope locking machine 9;

Step 7: start rope closing winch 7, put rope winch 8, change rope car 6, make them all be in pre-mode of operation;

Step 8: start gig 1, under all the other old hoisting rope tractions that do not disconnect, make on the lifting container I 11 carry, lifting container II 11 ' transfers, then the old hoisting rope 10 of two disconnections reclaims synchronously, newly hoisting rope 4 discharges synchronously, until lifting container I 11 moves to well head, lifting container II 11 ' moves to the shaft bottom, gig 1 stops, and then the old hoisting rope 10 of two disconnections all is recycled to well head, two described new hoisting ropes 4 are released into the shaft bottom, and two replacing lifting ropes of multi-ropes are finished;

Step 9: step 1 to the operation of step 8 is repeated one to twice, all the other hoisting ropes are changed take two as one group, the final replacing finishes whole four to six roots of sensation hoisting rope.

, change the rope car and follow operation as the active force of changing stylish, the old hoisting rope folding and unfolding of rope with gig.Change and remain in the rope process that at least two hoisting ropes do not break from elevator system, and all changing rope work all finishes at wellhead ground, carry on the lifting container I, the lifting container II transfers, newly, old hoisting rope is changing rope car inter-sync exchange, saved manpower, increase the safety of changing rope work, improved work efficiency.
