Abstract
The utility model relates to an abrupt prediction working equipment technical field is prevented to the mine, specifically is a feedleg is strutted in collapsible pneumatics. The problem of the large mining height fully -mechanized working face preventing that abrupt prediction in -process support protects group's board and can not satisfy and protect group's canopy guard requirement is solved, a feedleg is strutted in collapsible pneumatics, includes the detachable fork of falling the triangle, feedleg and collapsible supporting leg, the fork of falling triangle lower extreme and feedleg welded connection, and the feedleg lower extreme passes through hinge connection with collapsible supporting leg, the fork of falling the triangle including steel pipe and welding at the steel pipe of falling the triangle on steel pipe top, feedleg top welding have the tube head that is used for with pipe welding, the welding of feedleg bottom has the hinge, collapsible supporting leg include the landing leg steel pipe, the welding of landing leg steel pipe top has the steel sheet that is used for with hinge connection, the welding of landing leg steel pipe bottom has the landing leg.
Description
Technical field
The utility model relates to a kind of mine protrusion-dispelling prediction work equipment technical field, specifically a kind of collapsible pneumatic supporting air leg.
Background technology
High-seam working face operating personnel in protrusion-dispelling forecasting process will enter coal side and carry out drilling operation, the wall supporting that support face guard can not meet this technique completely protects top requirement, enter coal side and must carry out supporting, in the middle of old technique, personnel are when coal side is with the net supporting of lumps of wood top, although in operation off the net, not real net supporting being got up, does not reach the object of temporary lining.
There is following problem in old technology wall supporting: 1. operating personnel enter work to slip before the middle setting lumps of wood not by net supporting to top, do not form temporary lining, being equivalent to empty top operation, there is potential safety hazard in personnel's operation; 2. operating personnel is directly with lumps of wood top net, not only requires great effort but also swaying extremely unstable, easily cause security incident during operation.
Summary of the invention
The utility model can not meet at protrusion-dispelling forecasting process medium-height trestle face guard the problem that wall supporting protects top requirement in order to solve high-seam working face, provides a kind of collapsible pneumatic supporting air leg.
The utility model takes following technical scheme: a kind of collapsible pneumatic supporting air leg, comprises dismountable inverted triangle fork, air leg and foldable support leg, and inverted triangle fork lower end and air leg are welded to connect, and air leg lower end and foldable support leg pass through gemel connection; Described inverted triangle fork comprises steel pipe and is welded on the inverted triangle steel pipe on steel pipe top; Described air leg top is welded with for the tube head with steel-pipe welding, and air leg bottom welding has hinge; Described foldable support leg comprises supporting leg steel pipe, and supporting leg steel pipe top is welded with for the steel plate with gemel connection, and supporting leg steel pipe bottom welding has supporting leg.
Described air leg and foldable support leg are respectively equipped with handle.
Operating personnel is before entering the supporting of coal side, and in coal side, net is propped up by external application air leg completely, and after temporary lining, personnel enter the lumps of wood supporting of coal side again.
Compared with prior art, the utility model really solve personnel enter coal side supporting before, temporary lining is completed outside coal side, fully ensure operating personnel's job safety, reduce accident rate, efficiently convenient when entering the lumps of wood supporting of coal side, foldover design unique in the middle of this air leg ensure that and to exert advantages of oneself in the working space that down-hole is limited, its supporting intensity and portability are considered in the selection of material, through down-hole, experiment proves, air leg material can ensure two kinds of above-mentioned requirements completely, pneumatic design ensure that the operability in high gas and outburst mine, base grabs the stationarity that design ensure that air leg, configuration design is elegant in appearance.
