Abstract
The utility model relates to a kind of hydraulic support pin removal, belong to mine support plant equipment field, comprise holder, guide holder is established at holder middle part, and holder both sides are hinged jack respectively, and the telescopic shaft of jack is hinged sliding seat simultaneously, in sliding seat, towards holder, fix three grades and pull out cylinder, three grades are pulled out cylinder and are engaged in guide holder, and three grades are pulled out on a working end and establish screw thread, and the efficiency of pulling pin is high.
Description
Technical field
The utility model relates to a kind of hydraulic support pin removal, belongs to mine support plant equipment field.
Background technology
Under coal mine, need to use a large amount of hydraulic supports, the bearing pin of old hydraulic support connection member because the reason of subsurface environment and use is got rusty, is out of shape, is difficult to extract mostly, brings difficulty to further maintenance work.
Extracting of existing old hydraulic support bearing pin is mainly the method by artificial, and not only labour intensity is large, and the slow efficiency of the speed of extracting is low, and due to down-hole limited space, easily damages bearing pin and structural member.No matter be to extract efficiency, still extract quality, all can not meet the requirement of present hydraulic support maintenance work.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: the hydraulic support pin removal that a kind of efficiency of pulling pin is high is provided.
Hydraulic support pin removal described in the utility model, comprise holder, guide holder is established at holder middle part, holder both sides are hinged jack respectively, the telescopic shaft of jack is hinged sliding seat simultaneously, in sliding seat, towards holder, fix three grades and pull out cylinder, three grades are pulled out cylinder and are engaged in guide holder, and three grades are pulled out on a working end and establish screw thread.
Three grades pull out cylinder comprise three be nested together pull out cylinder, each pulls out the pin hole that is equipped with same size on cylinder, the adjacent cylinder that pulls out is fixedly connected with by pin, maximum one is pulled out cylinder and is fixed in sliding seat, minimum one is pulled out a working end and establishes screw thread.
Three grades are pulled out cylinder for cold drawn steel material, lightweight, are convenient to install.
Operation principle and process:
During work, first the end part of pin shaft damaging at hydraulic support bores upper screwed hole, three grades of ends of thread that pull out cylinder are tightened and coordinated with screwed hole, then at three grades, pull out on cylinder and select suitable pin hole with pin, the adjacent cylinder that pulls out to be connected and fixed, start jack, jack drives sliding seat jack-up, and sliding seat drives three grades to pull out cylinder the hydraulic support bearing pin of damage is extracted.
The beneficial effect that the utility model compared with prior art had is:
Hydraulic support pin removal described in the utility model, laborsaving, convenient, fast; Each parts adopt successively suit, save space; Pull out cylinder 1, pull out cylinder 2 and adopt cold drawing steel tube materials lightweight, be convenient to install, compare with the existing work of pulling pin, not only greatly reduce labour intensity, improved the efficiency of pulling pin, and significantly improved the quality of pulling pin, thereby guaranteed the repair quality of hydraulic support.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment schematic diagram.
In figure: 1, holder; 2, guide holder; 3, jack; 4, sliding seat; 5, three grades are pulled out cylinder; 6, pin pin hole; 7, pin; 8, hydraulic support; 9, bearing pin.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, hydraulic support pin removal described in the utility model, comprise holder 1, guide holder 2 is established at holder 1 middle part, holder 1 both sides are hinged jack 3 respectively, and the telescopic shaft of jack 3 is hinged sliding seat 4 simultaneously, fixes three grades pull out cylinder 5 in sliding seat 4 towards holder 1, three grades are pulled out cylinder and 5 are engaged in guide holder 2, and three grades are pulled out on cylinder 5 working ends and establish screw thread.
Three grades pull out cylinder 5 comprise three be nested together pull out cylinder, each pulls out the pin hole 6 that is equipped with same size on cylinder, the adjacent cylinder that pulls out is fixedly connected with by pin 7, maximum one is pulled out cylinder and is fixed in sliding seat 4, minimum one is pulled out a working end and establishes screw thread.
Three grades are pulled out cylinder 5 for cold drawn steel material, lightweight, are convenient to install.
Operation principle and process:
During work, first the end part of pin shaft damaging at hydraulic support bores upper screwed hole, three grades of ends of thread that pull out cylinder 5 are tightened and coordinated with screwed hole, then at three grades, pull out on cylinder 5 and select suitable pin hole 6 use pins 7 that the adjacent cylinder that pulls out is connected and fixed, start jack 3, jack 3 drives sliding seat 4 jack-up, and sliding seat 4 drives three grades to pull out cylinder 5 hydraulic support of damage 8 bearing pins 9 are extracted.
