Abstract
The utility model discloses a kind of device for quickly disassembling of mining supporting upright post, 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, and jack arranges support bar by rotating shaft.Can be convenient, fast, save time, the laborsaving dismounting that completes hydraulic support column fairlead, thereby improve maintenance efficiency, reduce maintenance cost.
Description
Technical field
The utility model relates to mine support plant equipment field, is specifically related to a kind of device for quickly disassembling of mining supporting upright post.
Background technology
Along with Chinese national economy is fast-developing, 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 during 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, to maintenance, brings difficulty.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 is used.
Summary of the invention
The technical problems to be solved in the utility model is: design a kind of device for quickly disassembling of mining supporting upright post, overcome above-mentioned defect, can be convenient, fast, save time, the laborsaving dismounting that completes hydraulic support column fairlead, thereby improve maintenance efficiency, reduce maintenance cost.
Solving the technical scheme that its technical problem adopts is: the device for quickly disassembling that designs a kind of mining supporting upright post, it is characterized in that, the holder that comprises 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, and jack arranges support bar by rotating shaft.
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 cover work open and compare with existing, not only greatly reduced labour intensity, improved maintenance efficiency, and significantly reduced maintenance cost, guaranteed that the just product of underground hydraulic support frame is used.

The specific embodiment
As shown in the figure, a kind of device for quickly disassembling of mining supporting upright post, the holder 1 that comprises anchor ear shape, holder 1 two parts are bolted, holder 1 outer wall stretches out and forms jack mounting rod 10, jack mounting rod 10 and jack 3 bottom-hinged, jack 3 arranges support bar 11 by rotating shaft; 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.
By jack, realize and tear fairlead 8 open, 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 cover work open and compare with existing, not only greatly reduced labour intensity, improved maintenance efficiency, and significantly reduced maintenance cost, guaranteed the normal use of underground hydraulic support frame.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 is used flexibly, easy accessibility.Jack 3 is hinged by bearing pin 4 and split pin 5 with jack mounting rod 10, and intensity is high, guarantees job safety.In order to guarantee the stability of this device, key position jack 3 laboriously particularly, the sliding top of the easy side direction of jack 3 when pressure is excessive, in order to guarantee safety, jack 3 arranges support bar 11 by rotating shaft, mixes up and when angle back support rod 11 withstands the anti-on-slip of jack 3 top, destroys overall structure.
During 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 work, make rotary sleeve 2 drive fairlead 8 rotations, unscrewed, be convenient to dismantle fairlead 8.
