Description

A kind of steeply pitching seam longwell adopts face lower end support

Technical field

This utility model relates to support apparatus in coal mine, is related specifically to a kind of steeply pitching seam longwell and adopts face lower end support.

Background technology

nullSteeply pitching seam longwell adopts the significant points that face lower end is supporting，Here equipment is many，Personnel are current frequently，Safety support pressure is big，The quality of its supporting quality，It is to determine the key point that can coal-face properly functioning，At present steeply pitching seam longwell is adopted the supporting of face lower end，Commonly use three frame end hydraulic supports to be arranged side by side towards coal-face tendency and carry out supporting，But there is bigger defect in such support pattern，If three frame end hydraulic supports are owing to suffering nearer，Disturb more when lifting each other，It is susceptible to occlusion，Furthermore it is the top board at end hydraulic support supporting，Become broken because repeatedly being supported by end hydraulic support，Drop in a large amount of broken gangues easily gap between three frame end hydraulic supports inside upstream end head bracket，Or be that the gangue of coal-face can rush and flies to alter in entrance end hydraulic support，These defects form huge potential safety hazard to the operating personnel in end hydraulic support，And enter the gap that the gangue in end hydraulic support has also taken up between end hydraulic support，Make cannot draw over to one's side between three frame end hydraulic supports，At this moment must stop producing，And supporting or the reach of end hydraulic support after carrying out substantial amounts of gangue cleaning work, could be realized，This not only adds the labor intensity of workman，And have impact on production efficiency significantly，Therefore design a kind of novel steeply pitching seam longwell and adopt face lower end support，To improving workman's working environment and solving steeply pitching seam longwell and adopt a face lower end supporting difficult problem and have great importance.

Summary of the invention

The purpose of this utility model is for existing deficiency, it is provided that a kind of steeply pitching seam longwell adopt face lower end support, operation is by interference to each other, and supporting is reliable, mobile fast and convenient.

nullThe technical solution of the utility model is achieved in that a kind of steeply pitching seam longwell is adopted face lower end support and mainly included left socle、Medium-height trestle、Right support、Double leval jib、Back timber、Base、Column、Advancing jack、Support case、Pedestrian's eye、Enter coal eye、Upper guard board、Side guard plate、Upper jack、Lower jack、Scratch board conveyor，Left socle、Medium-height trestle、Right support is the support of three frame independences，Each support has back timber and base，Couple between back timber with base and have column and double leval jib，Left socle is identical with right support structure，Left socle and right support lay respectively at medium-height trestle both sides，Medium-height trestle pan frontward end both sides by advancing jack respectively with left socle、The base of right support couples，Medium-height trestle base rear end couples with supporting case，Support and have pedestrian's eye above case、Enter coal eye，Upper guard board is arranged on the side supporting case top，Upper jack is arranged on the lower section of upper guard board，Lower jack is hinged on the side supporting bottom end，Side guard plate is connected in the side supporting case by upper jack and lower jack，Scratch board conveyor is placed on support case and medium-height trestle.

A kind of steeply pitching seam longwell that this utility model provides adopts face lower end support, left socle, medium-height trestle, right support is the support of three frame independences, each support has back timber and base, couple between back timber with base and have column and double leval jib, the quadric chain coupled has the ability of antitorque and anti-horizontal thrust, preferably improve the stability that three frame supports move up and down, left socle is identical with right support structure, left socle and right support lay respectively at medium-height trestle both sides, medium-height trestle pan frontward end both sides by advancing jack respectively with left socle, the base of right support couples, the three frame supports that base is coupled to each other advance in the way of taking a step, medium-height trestle rises frame, left, right support fall frame；nullMedium-height trestle fall frame，Left、Right support rises frame，With a left side、Right support and the medium-height trestle strong point each other，Stretching by advancing jack，Come for a left side、Right support provides power with medium-height trestle alternating forward，Medium-height trestle base rear end couples with supporting case，When medium-height trestle moves forward，Move forward together with the support case being connected in its base rear end，Realize supporting the purpose that case moves forward with this，Support case is body structure，Therefore closure is preferable，There is no more gap，Gangue can be effectively stoped to creep in support case，The top supporting case has pedestrian's eye，Purpose is to allow staff enter coal-face by pedestrian's eye in supporting case，The top supporting case has into coal eye，It is that the coal under allowing coal-face adopt enters in support case from there，And fall into be arranged on and be carried out coal-face on the scratch board conveyor supported in case，Upper guard board is arranged on the side supporting case top，Upper jack is arranged on the lower section of upper guard board，Lower jack is hinged on the side supporting bottom end，Side guard plate is connected in the side supporting case by upper jack and lower jack，Enter the walkway supported in case and be positioned at the side (namely side guard plate intersects formed supporting passage with upper guard board) supporting case，Upper guard board can be effectively prevented gangue above tunnel and drop in entrance walkway，And by the extension elongation of the upper jack of regulation with lower jack，The inclination angle of side guard plate can be controlled，It is allowed to preferably press close to lane side，To prevent tunnel lateral wall gangue to be caving in entrance walkway，Side guard plate and upper guard board define well protection to walkway.

The beneficial effects of the utility model are: a kind of steeply pitching seam longwell of offer adopts face lower end support, and security performance is high, and working environment is good, simple to operate, and translational speed is fast, reduce labor strength significantly and improve production efficiency.
