Description
Technical field
The utility model relates to one and protects apical organ technical field, is specially a kind of cantilever extension protector for underground driving working faces.
Background technology
In known technical field; in the industrial production; fire coal is absolutely necessary; and fire coal is generally excavated by underground mining; in the process of underground man-made recovery; often can cheat interior landslide, support the danger such as unstable, rubble drops, affect the life security of workman, also bring great hidden danger to safety in production simultaneously.At present, the driving face advance support of China's mine down-hole not yet effectively solves, because workman often newly will hang operation under the top board exposed after explosion, human casualty accident happens occasionally, the transformation of the way of its forestope articulated roof beam forms, add the fixing card with curved groove and slide card and annex, can the good i iron capplce of chain supporting, and carry out advance support as the strong point.Find by analyzing, the shortcoming of this scheme is: it is only applicable to flange beam stand, is not suitable for the support of other material, is not suitable with the needs of support apart from change, and the support of the inadaptable work plane that turns round uses, and does not solve the problem of workman's sky top operation completely.
Utility model content
For above-mentioned prior art Problems existing, the utility model provides a kind of cantilever extension protector for underground driving working faces.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cantilever extension protector for underground driving working faces, comprise expansion link, expansion coupling, the outer ceiling of circular arc, buffer spring, M shape support column, the outer ceiling of circular arc, fixed bar, check bolt, wire gauze, stretching device, control cabinet and interior expansion link, the inner side of the outer ceiling of described circular arc is provided with ceiling in circular arc, the support column that cross section is alphabetical M shape is provided with between ceiling in the outer ceiling of described circular arc and circular arc, described M shape supports and has installed buffer spring, it is large that stainless described fixed bar is fixed on ceiling and stroke in circular arc, interior expansion link quick and easy for installation, stainless described bottom of fixed has installed elasticity, good toughness and the wire gauze that should not get rusty, the spacing of described interior expansion link and external extension bar is fixed by check bolt, described interior expansion link and external extension bar are fixed on stretching device, described stretching device is the lifting being controlled expansion link by control cabinet.
Further, described a kind of locking check bolt of machinery that uses fixes stroke interior expansion link large, quick and easy for installation and external extension bar, makes it keep fixed range.
Further, the two ends of fixed bar described in stainless steel adopt electric arc welding to be fixed on the interior expansion link pillar large, quick and easy for installation of ceiling top and stroke in toughness and moulding good circular arc.
Further, described control cabinet that is simple to operate, Based Intelligent Control is connected on the stretching device of protection against electric shock by cable.
The beneficial effects of the utility model are: the utility model structure is simple, adopt the structure of double-layer circular curved support, make support more firm, larger load can be carried in limited installing space, simultaneously by the elastic buffer effect of circular arc steel plate, described wire gauze can bear the falling rocks under dropping in mine inside, can absorb the stress from ore deposit inside wall and pressure, overall structure is solid and reliable, improves the safety of workman's operation.
