Abstract

The invention provides a sliding type anti-toppling forepoling hydraulic support and an action method thereof, and relates to the technical field of mine equipment. The sliding type anti-toppling forepoling hydraulic support comprises a base, a stand column, a top beam, a sliding rod, a bottom sliding plate, a pushing jack, a swing base, a lifting jack and a supporting disc. Through cooperation of the lifting jack, the pushing jack and the like, self-movement can be achieved, so that the carrying flexibility of the support is improved; in the supporting process, the swing base, the lifting jack and the supporting disc are swung to the left side position and the right side position of the base and are kept consistent with the width direction of the rectangular base, a telescopic rod of the lifting jack extends to enable the supporting disc to make contact with a roadway bottom plate, and therefore the base is supported in the width direction of the rectangular base; the supporting span of the base in the width direction is increased, when a top beam of the support is separated from a roadway top plate, even if a roadway bottom plate is uneven, the hydraulic support cannot topple over, and the supporting stability of the hydraulic support is improved.

Description

technical field [0001] The invention relates to the technical field of mine equipment, in particular to a slip-type anti-dumping advance support hydraulic support and an action method thereof. Background technique [0002] The "Coal Mine Safety Regulations" requires that the length of the roadway for advance support in the mining face shall not be less than 20m. Previously, single pillars were generally used for advance support, and single pillars were used for advance support. The work intensity of the operators was high and the efficiency was low. The support effect is poor. With the upgrading of mining equipment, the advance support hydraulic support is generally used for the advance support of the roadway. During the mining advance process of the working face, it is necessary to move the advance support hydraulic support close to the working face to a position away from the working face one by one. However, the advanced support hydraulic support is relatively heavy, an...
