Description
technical field
The utility model relates to a kind of novel gob side entry hydraulic support, is applicable to coal face inclination angle from the gob side entry roadside support of 0 ° ~ 50 °.
background technology
Colliery forms a stope needs two tunnels, tradition coal winning technology, take over next stope and need tunnel again two tunnels, anxiety is taken in digging, driving speed is slow, large to high inclination-angle or high_dipping face supporting difficulty, reprocesses cost high, easily there is roof fall, tunnelling poor stability.If adopt gob side entry, can save coal one rock, greatly alleviate the nervous situation that digging is taken over, at work plane rear, gob side entry carries out manual operation, and common has certain danger along goaf supporting, so the support apparatus of gob side entry seems particularly necessary.
summary of the invention
As shown in figs. 1 and 3, hydraulic support adopts level Four clutch to rise frame to gob side entry hydraulic support of the present utility model, according to top board inclination angle size, adjusts supporting height.Hydraulic support base 1 as shown in Figure 1 rises frame heel pin 16 by clutch and rises frame base 2 with clutch and be connected, base 1 is connected with back timber 3 by top bottom girder column 5, back timber termination frame 4 embeds back timber 3 by back timber advancing jack 15, base 1 rises frame 12 by base oblique strut 6 with level Four clutch and is connected, back timber 3 rises frame 12 by back timber oblique strut 7 and level Four clutch, basic clutch rises frame 8 and is fixed on clutch and rises on frame base 2, basic clutch rises frame 8, one-level clutch rises frame 9, secondary clutch rises frame 10, three grades of clutches rise frame 11, and clutch rises frame 12 and by clutch, rises frame connecting pin 18 and be connected with level Four, clutch rises frame back timber 13 and is fixed on level Four clutch and rises on frame 12, back timber termination frame 4 rises frame back timber pin 17 by clutch and rises frame back timber 13 with clutch and be connected, moving towards jack 14 is connected with base 1, move towards jack 14 and control the reach of support.
During work, 3 of the back timbers that top bottom girder column 5 supports are supported by goaf back, basic clutch rises frame 8, one-level clutch and rises frame 9, secondary clutch and rise frame 10, three grades of clutches and rise the combination adjustment supporting height that frame 11 and level Four clutch rise frame 12, stop goaf downslide spoil, isolation goaf and tunnel, surfaceman's safety work space, as risen as shown in state diagram 3 and Fig. 4 along empty hydraulic support; During walking, shrink top bottom girder column 5, base oblique strut 6 and back timber oblique strut 7, falling the basic clutch of frame rises frame 8, one-level clutch and rises that frame 9, secondary clutch rise frame 10, three grades of clutches rise frame 11 and level Four clutch rises frame 12 to the state of not rising, then pass and move towards jack 14, see that gob side entry hydraulic support does not rise state diagram 1 and Fig. 2, after passing puts in place, rise top end column 5, base oblique strut 6 and back timber oblique strut 7 supporting top beam 3 supported laneway top boards, complete a circulation.
Basic clutch rises frame 8, one-level clutch and rises frame 9, secondary clutch and rises frame 10, three grades of clutches and rises frame 11 and level Four clutch and rises the every one-level of frame 12 and have certain stroke, with leaning on goaf side roof and floor variation adjustment highly, isolates goaf, work plane rear; The back timber 3 that top bottom girder column 5 and back timber oblique strut 7 supports adapts to the back that different angle change, shape as shown in figs. 1 and 3, and with back fluctuations, supporting, by goaf and back, is safeguarded tunnel working space, and is isolated goaf.
The utility model, has adopted level Four disengaging type structure design, and flexible jack telescopic oil cylinder supports, and moves towards the flexible propelling of jack, and supporting roof in tunnel, work plane rear, safeguards tunnel working space, isolation goaf.This supporting structure simplicity of design, compactness, bracing force are large, roof timbering is effective, operation is safe, and workman is easy for operation, safe and reliable, be very good gob side entry support apparatus, this support adapts to the work plane rear heading supporting of 0 ° ~ 50 ° inclination angles.
