Abstract
The utility model discloses a kind of covering device of tearing open of adopting mine hydraulic bracket, it is characterized in that, comprise the holder of anchor ear shape, holder two parts are bolted, holder outer wall stretches out and forms jack mounting rod, jack mounting rod and jack bottom-hinged; Comprise ring rotation cover, rotary sleeve and holder are coaxially installed, and rotary sleeve outer wall and jack telescopic shaft are hinged.Can be convenient, fast, save time, the laborsaving dismounting that completes hydraulic support column fairlead, reduce maintenance cost thereby improve maintenance efficiency.
Description
Technical field
The utility model relates to mine support plant equipment field, is specifically related to a kind of covering device of tearing open of adopting mine hydraulic bracket.
Background technology
Along with Chinese national economy fast development, and the needs of coal production high-yield and high-efficiency intensivization development, fully-mechanized mining working mechanization obtains the extensive use of large coal mine, seal on hydraulic support column fairlead belongs to consumable accessory, after need first removing fairlead when maintenance, change seal, because subsurface environment reason, fairlead gets rusty on the one hand, bracket upright post volume weight is all larger on the other hand, brings difficulty to maintenance.Existing hydraulic support fairlead is removed first because column volume weight is large, down-hole limited space, to first remove column by artificial method, then gug transports go back to manufacturer, re-use after specific purpose tool is removed fairlead and change seal, hand labor intensity is very big, and expends a large amount of financial resources, material resources and time.That labour intensity, maintenance efficiency and maintenance cost all can not meet the requirement that present underground hydraulic support frame uses.
Summary of the invention
The technical problems to be solved in the utility model is: design a kind of covering device of tearing open of adopting mine hydraulic bracket, overcome above-mentioned defect, can be convenient, fast, save time, the laborsaving dismounting that completes hydraulic support column fairlead, reduce maintenance cost thereby improve maintenance efficiency.
Solving the technical scheme that its technical problem adopts is: design a kind of covering device of tearing open of adopting mine hydraulic bracket, it is characterized in that, comprise the holder of anchor ear shape, holder two parts are bolted, holder outer wall stretches out and forms jack mounting rod, jack mounting rod and jack bottom-hinged; Comprise ring rotation cover, rotary sleeve and holder are coaxially installed, and rotary sleeve outer wall and jack telescopic shaft are hinged, on rotary sleeve inwall, establish keyway, in keyway, establish key, on holder inwall, establish rubber sleeve, play anti-skidding effect, jack and jack mounting rod are hinged by bearing pin and split pin.
Beneficial effect: the utility model is realized and torn open fairlead by jack, easy to operate, laborsaving; Tearing cover jack open is regular size, and cost is low; Rubber sleeve is between holder and column cylinder body, and protection hydraulic support column outer cylinder body surface is not by friction damage; Holder, rotary sleeve are directly set on column outer cylinder body, save space; Tear open compared with cover work with existing, not only greatly reduced labour intensity, improved maintenance efficiency, and significantly reduced maintenance cost, ensured that the just product of underground hydraulic support frame uses.

Detailed description of the invention
As shown in the figure, a kind of covering device of tearing open of adopting mine hydraulic bracket, comprises the holder 1 of anchor ear shape, and holder 1 two parts are bolted, and holder 1 outer wall stretches out and forms jack mounting rod 10, jack mounting rod 10 and jack 3 bottom-hinged; Comprise ring rotation cover 2, rotary sleeve 2 is coaxially installed with holder 1, rotary sleeve 2 outer walls and jack 3 telescopic shafts are hinged, on rotary sleeve 2 inwalls, establish keyway, in keyway, establish key 7, on holder 1 inwall, establish rubber sleeve 6, play anti-skidding effect, jack 3 is hinged by bearing pin 4 and split pin 5 with jack mounting rod 10.
Realize and tear fairlead 8 open by jack, easy to operate, laborsaving; Tearing cover jack open is regular size, and cost is low; Rubber 6 overlaps between holder 1 and column cylinder body, and protection hydraulic support column outer cylinder body surface is not by friction damage; Holder 1, rotary sleeve 2 are directly set on column outer cylinder body, save space; Tear open compared with cover work with existing, not only greatly reduced labour intensity, improved maintenance efficiency, and significantly reduced maintenance cost, ensured that the just product of underground hydraulic support frame uses.Tear cover jack 3 open for regular size, and be connected with existing hydraulic bracket control system, easy to operate, laborsaving; Rubber sleeve 6 is arranged between holder 1 and column outer cylinder body, protection column outer cylinder body surface be not fixed seat 1 friction damage; Key 7 uses flexibly, easy accessibility.Jack 3 is hinged by bearing pin 4 and split pin 5 with jack mounting rod 10, and intensity is high, ensures job safety.
When work, the holder of anchor ear shape 1 is stuck on column outer cylinder body 9 and is bolted, rotary sleeve 2 is enclosed within on fairlead 8, and fix by key 7 and the keyway on fairlead 8, jack 3 is worked, and makes rotary sleeve 2 drive fairlead 8 to rotate, unscrewed, be convenient to dismantle fairlead 8.
