Technical field
The utility model relates to support apparatus in coal mine, specially refers to a kind of comprehensive mining hydraulic bracket base reach guiding device.
Background technology
In recent years, China's comprehensive mechanical coal mining technical development is very fast, but because the colliery of China's exploitation flat seam is less, all there is certain angle of inclination in the coal seam in most of collieries.Seam inclination is big more, adopts the technical barrier of fully-mechanized mining just many more.The work of trying to stop people from fighting each other forward with hydraulic support of passing forward all is stretching out and retract completion through the hydraulic support pull bar like the scratch board conveyor in the fully-mechanized mining working.When the fully-mechanized mining working surface transporter need be passed forward, the hydraulic system of operation hydraulic support was slowly stretched out through pull bar; Promoting scratch board conveyor slowly moves forward; After scratch board conveyor reach puts in place,, can realize the hydraulic support work of trying to stop people from fighting each other forward through the operation of withdrawal pull bar.Because hydraulic support is in the process of trying to stop people from fighting each other, hydraulic support needs to become just stretchy hydraulic support reach of depressurization phase from holding state, when fully-mechanized mining working has certain inclination angle; The hydraulic support that is on the inclined plane will occur to lower slider; When seam inclination is big more, just big more to the danger of lower slider, therefore; Study and improve hydraulic support anti-fall and glide after move positive technology again, be still current combining and adopt one of important topic of technical research.
In the prior art, in order to solve the downward slippage problem of hydraulic support, one of its measure is exactly the free gap that as far as possible reduces pull bar cross connector, and the control hydraulic support does not produce or produce less downward slippage in the process of trying to stop people from fighting each other.Because front end at hydraulic support; There is pull bar cross connector to be fixedly connected with hydraulic support; The downslide amount of hydraulic support is less, but the rear end of hydraulic support is the goaf of coal-face, the technology that prior art does not also find anti-hydraulic support rear end to glide.Therefore, in the fully-mechanized mining working of certain seam inclination was arranged, when trying to stop people from fighting each other operation, the downslide amount of hydraulic support was just bigger, and causing hydraulic support deflection to occur can't keep plumbness with scratch board conveyor.Hydraulic support can not keep plumbness with scratch board conveyor, and the one, cause the pull bar of hydraulic support to keep plumbness with scratch board conveyor, influence the normal propelling of scratch board conveyor, even cause the downslide of scratch board conveyor; The 2nd, when downwards appears in hydraulic support,, difficultly hydraulic support is returned to scratch board conveyor keep vertical state fully because prior art do not have the hydraulic support deflection to move equipment.
Summary of the invention
The purpose of the utility model is: overcome the deficiency that prior art exists; A kind of comprehensive mining hydraulic bracket base reach guiding device is provided; After making fully-mechanized mining working surface hydraulic support produce the downslide deflection, can make hydraulic support in the process of trying to stop people from fighting each other forward, realizing automatically resets just moves; Make hydraulic support and scratch board conveyor remain on orthogonal state, solve hydraulic support and produce the positive difficult technical barrier that moves after the downslide deflection.
The technical scheme of the utility model is achieved in that a kind of comprehensive mining hydraulic bracket base reach guiding device, comprises hydraulic support foundation, pull bar, fixed head, guide strip, connecting pin, Scraper Conveyer Middle Trough, pull bar cross connector.On Scraper Conveyer Middle Trough, be connected with fixed head, be connected with guide strip on the fixed head, guide strip is fixed in the centre of fixed head through connecting pin; Said fixed head, guide strip are 1-2; The angle at upper and lower two angles of the front end of said hydraulic support foundation is identical with the angle of the hypotenuse of guide strip, makes the hypotenuse of guide strip become parallel contact with the hypotenuse at upper and lower two angles of hydraulic support foundation front end, and to hydraulic support in the reach process; Play and move positive guide effect; On the hypotenuse length of side of guide strip and the front end of hydraulic support foundation, the hypotenuse length of side at following two angles can be identical, also can be inequality.
The beneficial effect of the utility model is: because the utility model is connected with guide strip on scratch board conveyor; And change upper and lower two angles of hydraulic support front end into the oblique angle identical by the right angle with the guide strip angle; Make hydraulic support in the operating process of trying to stop people from fighting each other, become plumbness having produced the hydraulic support that glides and squint, having returned to scratch board conveyor; Realized hydraulic support in the reach process of trying to stop people from fighting each other, made the synchronous realization of hydraulic support move positive purpose voluntarily.
