Description
Technical field
It the utility model is related to a kind of side suspension roof support of coal mine roadway driving and the equipment that side anchor net laying is set, and in particular to
A kind of all-hydraulic side roofboltier of two-arm.
Background technology
The tunnelling in the big-and-middle-sized colliery in China at present uses the operating type of bolt and cable anchor supporting mostly.Tunnel initating
Afterwards, the stress of tunnel portion of side coal body is changed into two-phase stress from original three-phase stress, so as to the two of tunnel help to be formed compared with
Big stress concentration, under the effect of this situation, the strong point of coal side develops to coal body deep.Because coal body itself is more loose
It is soft, it may appear that the phenomenon of different degrees of wall caving, the supporting span in span length direction is increased, adds roadway support difficulty,
Also reduce support capacity of the coal body to top plate.
The stabilizing influence of coal side the reliability of whole Bolt System.The effect of side anchor pole is control side portion's coal body
Superficial part deforms, the intensity of reinforced design method superficial part coal body, prevents extrusion of the deep coal body to tunnel.Due to helping the clamping of anchor pole to make
With so that the coal body in the length range that anchor pole is controlled reaches synchronous deformation, can be born so that coal body forms one
Top and can is in the bearing bed moved integrally in the horizontal direction, improves the bearing capacity and stability of coal body.
At present, the supporting of the roll bolt of many working faces in colliery can substantially meet the demand of tunnelling, but due to existing

Fuselage carries out operation, and side anchor pole in bottom is particularly most next row side anchor pole, and operating personnel need to squat down or kneel on the ground operation, operation
Efficiency is low, operational security is poor；
(3) working equipment falls behind：Suspension roof support equipment far behind top suspension roof support equipment is helped, helps anchor supporting big at present
Hold electric coal drill using operating personnel more to be drilled, installation powder stick, the process for installing the multinomial manual work such as anchor pole and stirring,
Reverse torque and propulsive force apply by artificial；To ensure to help the pretightning force of anchor pole, also need to carry out two to mounted anchor pole
Secondary fastening.There is the problems such as operating environment is poor, labor intensity is high, low production efficiency；
(4) lapping, the difficulty of networking are big, need more people to build a framework and carry out operation of ascending a height, labor intensity is big, potential safety hazard compared with
Greatly；
(5) because the serious hysteresis of side anchor supporting, rib are also easy to produce wall caving, reduce support capacity of the rib to top plate.
