Ultrahigh-pressure large-diameter robot tool changing sealing seat assembly of full-face heading machine

Abstract

The invention relates to the technical field of heading machines, and discloses a full-face heading machine ultrahigh-pressure large-diameter robot tool changing sealing seat assembly which comprises a cutter head and a supporting cabin body, the supporting cabin body is composed of a connecting cabin, a transition cabin and a main cabin body which are sequentially arranged, first gates are movably inserted into the upper end and the lower end of the connecting cabin, and an access cabin opening is formed in the upper end of the main cabin body; a cabin door supporting frame is arranged in the circumferential direction of the edge of the access cabin opening, a second gate is movably inserted into the cabin door supporting frame, a base, a guide rail base, a transverse moving air cylinder and a tool changing mechanical arm are installed in the main cabin body, and the tool changing mechanical arm is used for penetrating through the supporting cabin body and stretching into the cutter head to conduct tool changing operation. By controlling the opening and closing states of the first gate and the second gate and cooperating with transverse movement of the base and deformation adjustment of the tool changing mechanical arm in the tool disc, the automatic tool changing process of the abraded tool can be achieved, and the comprehensive coverage and adjustment flexibility of the automatic tool changing process are improved.

Description

technical field [0001] The invention relates to the technical field of roadheaders, in particular to an ultra-high pressure large-diameter robot tool change sealing seat assembly for a full-face roadheader. Background technique [0002] At present, the cutter heads of roadheaders used in tunnel engineering are as follows: figure 1 As shown, it mainly includes a cutter head frame, a hob and a cutter head cabin. The cutter head frame is used for installing and arranging the hob, and the hob is used for breaking rock and soil layers. When the hob is severely worn and needs to be replaced, in the prior art it is often necessary to manually enter the hob cabin to perform manual tool change operations on the hob, and the manual tool change operation is not only labor-intensive, but also due to the The environment is closed, the oxygen content is low, and harmful gases accumulate. The process of manual tool change will endanger the health of workers. Therefore, the present applic...
