Abstract

The utility model relates to a valve remover, belonging to the tool class. The utility model which is exclusively used for dismounting the three-purpose valve of a mining hydraulic prop can be used for replacing the manual dismounting The utility model which can not damage the valve cylinder and the valve core of the three-purpose valve has reliable work and high efficiency. The utility model is an ideal tool used for dismounting the three-purpose valve.

Description

Valve remover

Valve remover belongs to the instrument class, the Valve remover tool.

Prior art all is to use the artificial unloading to the triple-use valve of mining hydraulic prop, and no special tool promptly inserts the valve cylinder removal hole with crowbar, and manpower rotates and splits out right valve cylinder, beats the triple-use valve core with hand hammer again, draws off left valve cylinder, fragile triple-use valve, and labour intensity is big.

The object of the present invention is to provide a kind of two-way Valve remover, this Valve remover adopts machine driven system, blocks triple-use valve left and right sides valve cylinder with two special carriers, rotates and add an axial force to make left and right sides valve cylinder withdraw from hydraulic prop automatically.

The right chuck structure schematic diagram of Fig. 2;

The right chuck A-A of Fig. 3 sectional drawing;

Fig. 4 left side chuck structure schematic diagram;

Fig. 5 left side chuck B-B sectional drawing;

Now by reference to the accompanying drawings 1 the explanation this Valve remover technical scheme, this Valve remover is by motor 1, the drive pulley 2 that connects with motor shaft, V belt 3, be fixed on the negative pulley wheel 4 of main shaft 6 lower ends, main shaft is fixed on the body 20 with two bearing blocks 5, vertical shaft upper end key connecting driving bevel gear 7, left and right sides power transmission shaft 14 on same axis, be axially fixed on the body 20 with two bearing blocks 10 respectively, the little Cylindrical gears 12 in the difference key dress left and right sides on the power transmission shaft, in the respectively passive bevel gear 17 in the key dress left and right sides and driving bevel gear 7 engagements of transmission axle head, left and right sides screw mandrel 9 splines on same axis are equipped with left and right sides big column gear 11, respectively with little Cylindrical gears 12 engagements in the left and right sides, the end of thread of screw mandrel and optical axis partly are fixed on the body 20 with left and right sides nut seat 8 and bearing block 13 respectively, workbench 16 and limit switch are housed above the body form. It is characterized in that left and right sides screw mandrel 9 about end left chuck 15, right chuck 18 arranged. Referring to accompanying

drawing

2,3, 4,5, right chuck 18 is sleeve-shaped, upper surface radiation is offered a plurality of radial direction through hole 21, and sliding sleeve 19 arranged, left chuck 15 symmetry on collet body 26 is equipped with adjustable cramp 22 usefulness bearing pins 25 and is connected on the collet body, upper clamp middle part has through hole, and lower clamp has screw fishbolt 24 is housed, and there is spring 23 centre.

The working condition of this Valve remover is, hydraulic prop is lain on the workbench, and triple-use valve left and right sides valve cylinder is just in time aimed at left and right sides chuck, left side valve cylinder is the garden cylindricality, by the end dismounting garden annular groove is arranged, and bottom land is flat-shaped, right valve cylinder body is the garden cylindricality, has by the place, end and radially dismantles through hole.Starter motor is through above-mentioned machine driven system, it is close that left and right sides screw mandrel drives left and right sides chuck, make the clamp of left chuck aim at triple-use valve dismounting garden annular groove, the crawl motor makes flat horizontal surface at the bottom of the alignment slot of tong chops plane, tighten fishbolt 24 with the socket wrench specially adapted for it spanner, right chuck 18 is offered a plurality of radial direction through hole, and available bearing pin inserts the removal hole of triple-use valve left side valve cylinder at random, sliding sleeve 19 is moved axially seal bearing pin again.Restart the motor counter-rotating, then the moment of torsion of left and right sides chuck makes left and right sides valve cylinder counter-rotation and axially leaves, and until drawing off hydraulic prop, unclamps fishbolt, under spring 23 effects, jaw opens and takes out left valve cylinder, returns sliding sleeve 19, take out bearing pin, take down right valve cylinder, finish whole dismantlement work.Limit switch is just controlled the ultimate range that screw mandrel leaves, and protects positive machine.

This Valve remover is exclusively used in the triple-use valve of the mining hydraulic prop of dismounting, reliable operation, and the efficient height can not damage triple-use valve.Mine underground jobs such as colliery, gold mine, iron ore adopt hydraulic prop to become main support form at present, and consumption is big.Dust is more in the mine, and there was dampness in the air, and hydraulic prop produces phenomenons such as bending, corrosion, leakage after a period of time is used in the down-hole, need often overhaul.All be the artificial unloading now, the serious artificial dismounting that is difficult to of the corrosion that has, general triple-use valve spoilage uses this Valve remover can reduce maintenance worker's labour intensity greatly up to 10%, improves working conditions.
