The invention relates to coal mine underground support equipment, in particular relates to a track traveling forepoling support with a side shifter, and aims at solving the technical problem that a top plate is supported repeatedly by a forepoling support of a coal face. The support comprises a rigidly connected whole structure type base, a track traveling device, lift devices, a link mechanism, a support caving shield, a top beam, a bidirectional side shifter device and a face guard, wherein the lift devices are arranged on two sides of the base, top ends of the lift devices are hinged with the lateral sides of the base, and bottoms of the lift devices are connected with the track traveling device; the base is provided with the link mechanism; the link mechanism is connected with the support caving shield; the support caving shield is hinged at the rear end of the top beam; the face guard is arranged on the lateral side of the top beam; the shielding direction of face guard is vertical to the track travelling direction; and the bidirectional side shifter device is arranged on the lateral side of the base. The brand-new advanced mechanical support equipment is provided to forepoling support of the coal face, and the actual production requirement is fulfilled.
Description
technical field [0001] The patent of the present invention relates to underground support equipment in coal mines, in particular to a crawler walking advance support bracket with a side shifting device. Background technique [0002] Coal mine safety regulations require that advance support must be carried out within 20m of the trough on both sides of the working face. The general advance support support is moved forward and then pulled, moving forward in sequence, and there is a problem of repeatedly supporting the roof. The reason is that the current hydraulic support structure is relatively simple. Except for the size change, the main structure is basically unchanged. Although this can meet the conditions of most mining areas, it is inconvenient to use in some special occasions and cannot reach the support level. protection requirements. Contents of the invention [0003] The purpose of the present invention is to solve the technical problem of repeatedly supporting the...
