Embodiment Construction

[0007] Such as figure 1 Shown: the present invention includes the hollow shaft 6 that is arranged in the casing cylinder 1 of the roadheader, the rear portion of the hollow shaft 6 is connected with the gear box 12 and the motor 15 , and the front portion of the hollow shaft 6 is fixedly connected with the outer cutter head 2 . The power of the motor 15 drives the gear 10 through the input shaft 14 in the gearbox 12, meshes with the gear 23 on the hollow shaft 6, drives the hollow shaft 6 to rotate, and drives the outer cutter head 2 to rotate, and the cutter on the outer cutter head 2 4. Cut the rock and soil on the peripheral part of the face.

[0008] Inside the hollow shaft 6, a central shaft 19 is interspersed, its rear part is connected with the gear box 12 and the motor 15, and the front part of the central shaft 19 is fixedly connected with the inner cutterhead 3. Gear box 12 li is provided with intermediate shaft 17, and idler gear 16 is housed on it. The power of t...

Abstract

The invention discloses a single-power anti-torsion and even-abrasion heading machine suitable for underground engineering construction. The heading machine is composed of an inner cutter disc located in the center and an outer cutter disc located on the periphery. As the rotating directions of the two cutter discs are different, autorotation generated during working of the heading machine can be overcome. As the rotating speeds of the two cutter discs are different, the rotating speed of the inner cutter disc is high, and the rotating speed of the outer cutter disc is low, linear speeds of radial points on the cutter discs are balanced, and therefore abrasion of cutting devices on the cutter discs is balanced. Shutdown maintenance only caused by abrasion of parts of cutting devices is reduced, and the use efficiency of the heading machine is improved. As the inner cutter disc and the outer cutter disc are driven by a power system, the occupied space of the device is reduced.

Description

technical field [0001] The invention is a single-power anti-torsion uniform wear boring machine, which is suitable for the construction of urban underground pipeline facilities, subways, tunnels and other underground projects. Background technique [0002] Existing roadheaders are all provided with a cutterhead conforming to the diameter of the built tunnel, and on the cutterhead facing the side of the tunnel face, several fixed or freely rotating cutters are housed. Next to the rear part of the cutter head is a cylinder as the casing of the roadheader, and a shaft that can rotate around the tunnel axis is supported by a bearing in the center of the cylinder. The front end of the rotating shaft is connected with the cutter head, and the rear part is connected with the gear box and the motor. The power of the motor drives the rotating shaft through the gearbox, and then drives the cutter head to rotate, and the rock and soil are cut through the cutter on the cutter head. Th...
