Abstract
The utility model relates to a sleeve detacher for a hydraulic support stand column and belongs to the field of mine supporting mechanical equipment. The sleeve detacher comprises a hoop-shaped fixed base, wherein the two parts of the fixed base are connected through a bolt, the outer wall of the fixed base extends outwards to form a jack mounting rod, and the jack mounting rod is hinged to the bottom of a jack. The sleeve detacher comprises an annular rotating sleeve, the rotating sleeve and the fixed base are coaxially arranged, and the outer wall of the rotating sleeve is hinged to a telescopic shaft of the jack. The sleeve detacher can conveniently and rapidly detach a guide sleeve of the large mining height hydraulic support stand column in a time-saving and labor-saving mode.
Description
Technical field
The utility model relates to a kind of hydraulic support column and tears cover device open, belongs to mine support plant equipment field.
Background technology
Along with Chinese national economy is fast-developing, and the needs of coal production high-yield and high-efficiency intensivization development, the large mining height hydraulic support of realizing fully-mechanized mining working high-yield and high-efficiency obtains the extensive use of large coal mine.The seal that large mining height hydraulic support guide pillar puts belongs to consumable accessory, after need first removing fairlead during maintenance, change seal, because subsurface environment reason, fairlead gets rusty on the one hand, support with great mining height column volume weight is all larger on the other hand, to maintenance, brings very large difficulty.
Existing large mining height 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 special 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 now large mining height hydraulic support is used.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of can be convenient, fast, save time, laborsavingly complete the hydraulic support column that large mining height hydraulic support guide sleeve of stand column removes and tear cover device open.
Hydraulic support column described in the utility model is torn cover device open, comprises the holder of anchor ear shape, and holder two parts are bolted, and 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 cottor pin, and intensity is high, guarantee job safety.
Operating principle and process:
During work, the holder of anchor ear shape is stuck on column outer cylinder body and is bolted, rotary sleeve is enclosed within on fairlead, and fix by the keyway on key and fairlead, jack work, makes rotary sleeve drive fairlead rotation, unscrewed, be convenient to dismantle fairlead.
The beneficial effect that the utility model compared with prior art had is:
Hydraulic support column described in the utility model is torn cover device open and is realized and torn open fairlead by jack, easy to operate, laborsaving; 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.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment schematic diagram;
Fig. 2 is upward view embodiment illustrated in fig. 1.
In figure: 1, holder; 2, rotary sleeve; 3, jack; 4, bearing pin; 5, cottor pin; 6, rubber sleeve; 7, key; 8, fairlead; 9, column outer cylinder body; 10, jack mounting rod.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As depicted in figs. 1 and 2, hydraulic support column described in the utility model is torn cover device open, comprises the holder 1 of anchor ear shape, and 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;
Comprise ring rotation cover 2, rotary sleeve 2 is coaxially installed with holder 1, and 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 cottor pin 5 with jack mounting rod 10, and intensity is high, guarantees job safety.
Operating principle and process:
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.
