Abstract
The utility model is specially a kind of hydraulic support lateral arrangement operating valve hand stopping means, solves the problem that existing operating valve hand does not have stopping means potential safety hazard.Hydraulic support lateral arrangement operating valve hand stopping means, comprise and be positioned at the operating valve hand left and right sides and the limiting plate fixing with hydraulic support, the both sides, front and back of limiting plate all have draw-in groove corresponding to left and right, the gag lever post being positioned at both sides before and after operating valve hand is placed with in the draw-in groove that left and right is corresponding, limiting plate outside gag lever post is fixed with the sleeve pipe be positioned at above draw-in groove, be installed with the spacer pin of afterbody bending in sleeve pipe, the tail support of spacer pin is being fixed on the card column on limiting plate.The utility model meets the requirement of safety quality standard construction, has stopped the potential safety hazard that coal production exists, has had that material cost is lower, easy installation and removal and use the advantage of flexibility and reliability.
Description
Technical field
The utility model relates to underground mine use stopping means, is specially a kind of hydraulic support lateral arrangement operating valve hand stopping means.
Background technology
" safety quality standard construction standard " puts coal mining secure quality standardizatio standard-required, roof control the 5th event in Section 3 order quality and safety to combining to adopt to combine, and requires hydraulic support operating valve hand limited location device.
But existing hydraulic support operating valve hand does not have stopping means, does not meet safety quality standard construction requirement, also there is the potential safety hazard on producing simultaneously.
Summary of the invention
The utility model does not have the problem of stopping means potential safety hazard in order to solve existing operating valve hand, provide a kind of hydraulic support lateral arrangement operating valve hand stopping means.
The utility model adopts following technical scheme to realize: hydraulic support lateral arrangement operating valve hand stopping means, comprise and be positioned at the operating valve hand left and right sides and the limiting plate fixing with hydraulic support, the both sides, front and back of limiting plate all have draw-in groove corresponding to left and right, the gag lever post being positioned at both sides before and after operating valve hand is placed with in the draw-in groove that left and right is corresponding, limiting plate outside gag lever post is fixed with the sleeve pipe be positioned at above draw-in groove, be installed with the spacer pin of afterbody bending in sleeve pipe, the tail support of spacer pin is being fixed on the card column on limiting plate.
The utility model reasonable in design is reliable, meet the requirement of safety quality standard construction, stopped the potential safety hazard that coal production exists, have processing technology simple, use that material category is few, material cost is lower, easy installation and removal and use the advantage of flexibility and reliability.
