Abstract
The utility model provides a hydraulic support upright repair tool which comprises a circular ring, a plurality of jack screws arranged on the circular ring and a handle. Due to the fact the circular ring is fixed on a nut pressure plate of an upright cylinder body through the jack screws, the hydraulic support upright repair tool is capable of dismantling nuts on the upright cylinder body and achieving inspection and repair of an upright through turning of the handle and the grind principle without dismantling the upright and transporting the dismantled upright to the ground to repair, improving inspection and repair efficiency and reducing safety hazard.
Description
Technical field
The utility model belongs to comprehensive mining hydraulic bracket reparation special tool under the coal mine, relates to hydraulic support column repair outfit under the particular surroundings of a kind of down-hole.
Background technology
Comprehensive mining hydraulic bracket is the very important support apparatus of fully-mechanized mining working, and column is the main load bearing component of hydraulic support, the shock resistance of hydraulic support realizes by column that mainly under the bump effect, column will be in case damage will directly affect safety in production.So in the situation that larger at support strength, critical component is heavier, be difficult for copying mechanically, in case the Hydraulic Elements such as column, passing break down, repair just very inconvenient.Such as the column bad seals, between Ground Vehicle, change after then column must being removed gug during replacing, brought pressure to transportation system, the cost that has increased sector drops into, and exists larger potential safety hazard in simultaneously demolition, installation, the fortune process.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic support column repair outfit for the colliery down-hole combined mining working.
For achieving the above object, the utility model has adopted following technical scheme:
Comprise annulus and be arranged at intervals at several jackscrews and handgrip on the annulus.
Described jackscrew is along the radially setting of annulus.
Be provided with boosting-rod on the described handgrip.
Hydraulic support column repair outfit described in the utility model utilizes jackscrew that annulus is fixed on the pillar upper cylinder body nut, then by rotating handgrip, the utilization principle of turning a millstone is dismantled column upper cylinder body nut, can overhaul column, need not to repair being transported to ground after the column dismounting, improve overhaul efficiency, reduced potential safety hazard.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is operating principle schematic diagram of the present utility model;
Among the figure: the 1-jackscrew; The 2-annulus; The 3-handgrip; The 4-boosting-rod; 5-upper cylinder body nut; The 6-telescoping cylinder; The 7-column; 8-column bore seal.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1, the utility model comprises annulus 2 and is arranged at intervals at several jackscrews 1 and handgrip 3 on the annulus 2 that described jackscrew 1 is provided with boosting-rod 4 along the radially setting of annulus 2 on the described handgrip 3.
Utilize the thick steel plate of 20-40mm, be processed into circular being enclosed within on the column cylinder body, again according to four aperture positions of column upper cylinder body nut, jackscrew at annulus design M16-24, then the handgrip of burn-oning in the annulus outside, the principle that utilization is turned a millstone is dismantled column upper cylinder cover nut, can overhaul column, uses the same method after having overhauled to install the cylinder body nut and get final product again.
Embodiment
A kind of being exclusively used in repaired the special tool that column uses under the particular surroundings under the coal mine, it is comprised of jackscrew, O type annulus, handgrip, boosting-rod four parts.
The ejector pin of at first telescoping cylinder 6 of column 7 being dismantled is regained, being processed into annulus 2 with the thick steel plate of 20mm-40mm is enclosed within on the column cylinder body, again on ring steel plate according to four aperture positions of upper cylinder body nut 5, the jackscrew 1 of design M16-24, utilize jackscrew that annulus is connected with upper cylinder body nut 5, the handgrip 3 of burn-oning at diagonal angle, the annulus outside again, put boosting-rod 4 during effort, the principle that utilization is turned a millstone is dismantled column upper cylinder body nut 5, get final product replacing columns bore seal 8 or maintenance column, the first-class upper cylinder body nut that uses the same method again after having overhauled gets final product.
The beneficial effects of the utility model and technical characterictic:
1, draw materials conveniently, process simple.
2, all can use in light and flexible, convenient in carrying, any specific condition.
3, simple to operate, practical, safety factor is high.
4, alleviate operating personnel's labour intensity, avoided the generation of transportation, handling safety accident, the surplus lot of materials is taken simultaneously, can obtain good result of use.
