Abstract
The utility model relates to an underground protecting device for a coal mine, and in particular relates to a protecting device for a hydraulic support, solving the problem of the conventional hydraulic support that the upright column is easily damaged due to blast firing. The protecting device for the hydraulic support comprises a scroll rack and a hydraulic motor, wherein the scroll rack is arranged below a top beam, and the hydraulic motor is positioned at the back of the scroll rack; a scroll is arranged at the lower part of the scroll rack; a protecting curtain is coiled on the scroll and is composed of a rubber coating and a steel wire gauze positioned into the rubber coating; a driven chain wheel is arranged at one end of the scroll; an operating valve set is connected to the hydraulic motor; a driving chain wheel is connected to an output shaft of the hydraulic motor; and a transmission chain is arranged between the driving chain wheel and the driven chain wheel. The protecting device for the hydraulic support is reasonable and reliable in structural design, overcomes the problem of the conventional hydraulic support that the upright column is easily damaged due to the blast firing, prolongs the service life of the hydraulic support, reduces the cost of maintaining the hydraulic support, effectively safeguards equipment and personal safety, and has the advantages of being reasonable in layout, convenient to operate, and saving the cost.
Description
Technical field
The utility model relates to protector under the coal mine, is specially a kind of hydraulic support protector.
Background technology
Fully-mechanized mining working under the coal mine utilizes hydraulic support, scraper plate machine, coal-winning machine comprehensive mining, when crossing tomography, blow out the slungshot that produces, fly coal, fly slag damage is caused on operating valve set, sebific duct, pressure meter and the column oil cylinder surface of hydraulic support.Therefore the main cause of the visual plant hydraulic support of coal mining face timbering inefficacy is the damage on control valve, sebific duct, pressure meter and column oil cylinder surface, and the inner string of the big column of hydraulic support column oil cylinder piston bar plating face damage formation liquid is the main cause that causes the hydraulic prop inefficacy.
Column is the main load hydraulic component of hydraulic support, and the quality of its performance plays an important role to the safety in production of mining face under mine, therefore, in use how to protect big column and each oil cylinder, and crucial meaning is all arranged.
Summary of the invention
The utility model is blown out for the column that solves existing hydraulic support influences flimsy problem, and a kind of hydraulic support protector is provided.
The utility model is to adopt following technical scheme to realize: the hydraulic support protector, comprise scroll rack that is arranged on the back timber below and the hydraulic motor that is positioned at the scroll rack rear, the scroll rack bottom is provided with spool, be wound with cutting means enclosure on the spool, cutting means enclosure is made up of rubber and the gauze wire cloth that is positioned at it, and an end of spool is provided with driven sprocket, be connected with operation valve group on the hydraulic motor, and be connected with drive sprocket on the hydraulic motor output shaft, be provided with driving chain between drive sprocket and the driven sprocket.
When crossing tomography, open operating valve set, when operation valve group is in down position, come to such an extent that highly pressurised liquid enters inlet under the fluid-power motor by the right position of control valve from emulsion power pack, the hydraulic motor backward rotation, cutting means enclosure descends by chain drive, puts to scraper plate pusher side plate bottom by preventing cutting means enclosure, with protection hydraulic support column oil cylinder, sebific duct etc. do not blown out the slungshot that produces, fly coal, institute injures; Finish using the back by the control valve commutation, when making the operation valve be in lifting position, come to such an extent that highly pressurised liquid enters inlet on the fluid-power motor by position, a control valve left side from emulsion power pack, the hydraulic motor forward rotation, cutting means enclosure rises by chain drive; Thereby reach the purpose of protection hydraulic support.
The utility model reasonable in design is reliable, the column that has overcome existing hydraulic support is blown out the flimsy problem that influences, prolonged the application life of hydraulic support, reduced the recondition expense of hydraulic support, and equipment and personal safety are all ensured to have advantage rationally distributed, easy to operate and that save cost effectively.
