Mobile advance support system and support method

Abstract

The invention relates to a movable forepoling system and a supporting method.The movable forepoling system comprises a frame moving unit and a plurality of double-supporting frame bodies which are sequentially arranged in the length direction of a roadway, each double-supporting frame body comprises two single-body supports which are fixedly connected into a whole, and the two single-body supports are arranged in the length direction of the roadway; the side rods are hinged to the two ends of the arc-shaped ejector rod through upper transverse hinge shafts respectively, the jacking oil cylinders are hinged to the lower ends of the side rods through lower transverse hinge shafts, and the arc-shaped ejector rod and the two side rods form an arch shape matched with the section of a roadway. A first telescopic device for driving the side rod to rotate towards the inner side of the arch around the upper transverse hinge shaft is mounted on the arc-shaped ejector rod; and the frame moving unit comprises a working platform and a driving device for driving the working platform to move in the length direction of the roadway, a second telescopic device is installed on the working platform, the extending part of the second telescopic device stretches out and draws back in the vertical direction, and a rod clamping device located below the arc-shaped ejector rod is installed on the extending part of the second telescopic device.

Description

technical field [0001] The invention relates to the technical field of roadway support, in particular to a mobile advanced support system and a support method. Background technique [0002] At present, the roadway of coal mines mainly adopts advanced support, roadheader operation (roadheader driving, slag removal), and permanent support to carry out the excavation operation. There is a potential safety hazard on the roof; second, the excavation needs to wait for the completion of the advance support before it can be carried out, and the operation is discontinuous, resulting in low operation efficiency. SUMMARY OF THE INVENTION [0003] Aiming at the above-mentioned problems existing in the traditional operation mode, the present invention provides a mobile advanced support system and a support method, which shortens the time for the advance support and the empty roof, and realizes the continuous operation of the excavation process. [0004] The present invention is achiev...

Problems solved by technology

[0002] At present, coal mine roadways mainly adopt advance support, roadheader operation (roadheader excavation, slag discharge), and permanent support for excavation operations. There are potential safety hazards on the roof; the second is that the excavation needs to wait for the advance support to be completed before proceeding, and the operation is discontinuous, resulting in low operation efficiency
