Description
Technical field
The present invention relates to support apparatus in coal mine, specially refer to a kind of puppet oblique comprehensive mining hydraulic bracket of bowing.
Background technology
Hydraulic support is the comprehensive support apparatus of adopting of work plane growing up on the bases such as friction prop and hydraulic prop, be widely used in coal-face, yet bow in oblique coal-face in puppet, but seldom see and utilize hydraulic support to produce, mainly because hydraulic support is used and has problems at bow oblique coal-face of puppet, the frame type of existing hydraulic support is not suitable with at bow oblique coal-face of puppet and arranges, after can not automatic moving during as hydraulic moving stand just causing gliding, recover difficulty, anti-skidding anti-down jack is difficult for installing, hydraulic support is adjusted frame difficulty, personnel are passless smooth etc. working surface hydraulic support expert, the spoil in goaf is easily scurried into internal stent etc., the key technology that present stage addresses these problems does not realize breakthrough, cause the puppet oblique coal-face of bowing to abandon comprehensive mining hydraulic bracket, and adopt the coal-mining method that traditional productivity is comparatively low, as adopt pseudo-tiltedly flexible type shield to exploit, this coal-mining method mechanization degree is low, labor strength is large, safety factor is low, output is not high, therefore invent and a kind ofly can adapt to the puppet hydraulic support that oblique coal-face produces of bowing, to expanding colliery comprehensive mechanization, produce, improve workman's condition of labor, tool is of great significance.
Summary of the invention
The object of the invention is for existing deficiency, the puppet the providing oblique comprehensive mining hydraulic bracket of bowing, be applicable to the puppet oblique coal-face installation and use of bowing, overcome the various restriction factors that hydraulic support is used in puppet is bowed oblique coal-face, for bow oblique coal-face comprehensive mechanization of puppet is produced high-quality adequate and systematic service is provided.
Technical scheme of the present invention is achieved in that a kind of puppet oblique comprehensive mining hydraulic bracket of bowing, and mainly comprises base, base front end, pass a bridge, column, back link, back link back, back link side guard board, caving shield, caving shield back, caving shield side guard board, back timber, top beam rear end, guiding device, scratch board conveyor, rib, base front end is hypotenuse, base front end hypotenuse is parallel with scratch board conveyor, gap bridge is parallel to base front end hypotenuse and is fixed on base, column is parallel to gap bridge, the back link side guard board arranged in dislocation of back link both sides, the back link side guard board of Kao Ji lane side is higher than the back link side guard board by air way side, back link back is inclined-plane, inclined-plane, back link back is parallel to gap bridge, the caving shield side guard board arranged in dislocation of caving shield both sides, the caving shield side guard board of Kao Ji lane side is higher than the caving shield side guard board by air way side, caving shield back is inclined-plane, inclined-plane, caving shield back is parallel to gap bridge, top beam rear end is hypotenuse, one end that caving shield connects with back timber is hypotenuse, one end of caving shield hypotenuse parallel with top beam rear end and the two be coupled to each other.
The puppet provided by the invention oblique comprehensive mining hydraulic bracket of bowing, scratch board conveyor is laid along the coal-face puppet tilted direction of bowing, base front end hypotenuse is parallel with pseudo-scratch board conveyor of bowing on oblique coal-face, because of base front end parallel with scratch board conveyor, when hydraulic support is tried to stop people from fighting each other, base front end can be pressed close to the guiding device on scratch board conveyor preferably, under the effect of guiding device, the hydraulic support automatic moving gliding just, try to stop people from fighting each other each time and all carry out the downslide reset of hydraulic support, effectively overcome the downslide difficult problem that hydraulic support is bowed in oblique coal-face in puppet, in puppet, bow on oblique coal-face, column is parallel to gap bridge, column line is parallel with scratch board conveyor, every hydraulic support foundation front end is parallel with scratch board conveyor, all hydraulic support foundation front end line is parallel with scratch board conveyor, gap bridge on every hydraulic support is parallel to base front end hypotenuse, pseudo-gap bridge line of bowing on oblique coal face hydraulic support base is parallel to scratch board conveyor, between gap bridge and scratch board conveyor, form a ramp way thus, this passage and the puppet slanting face rib of bowing is parallel, personnel walk very convenient on this passage, successfully solve puppet and bowed slanting face hydraulic support because of dislocation up and down, the upper and lower obstructed difficult problem of column and gap bridge obstruction personnel, the ramp structure at caving shield and back link back, from air way Xiang Ji lane direction thickening gradually, from air way Wang Ji lane direction, the puppet caving shield on oblique coal face hydraulic support of bowing, back link, be arranged in two neat inclined-planes, these two inclined-planes are all parallel with the puppet of the rib tilted direction of bowing, this structure has effectively prevented that the spoil in goaf from scurrying into internal stent from the hydraulic support rear portion of dislocation, and can first move while having realized hydraulic moving stand added, greatly facilitate the tune frame between hydraulic support in coal-face.
The invention has the beneficial effects as follows: the puppet the providing oblique comprehensive mining hydraulic bracket of bowing, personnel are current convenient, adjust frame easy, effectively control hydraulic support and glide and prevent that spoil from scurrying into internal stent from goaf, and the puppet oblique coal-face environment of bowing is had to good compliance.
