Embodiment 2

[0051] The dislocation arrangement structure in the second embodiment is, as Figure 8 As shown, the second group of crawler traveling mechanisms is arranged at a position close to the inner side of the roadheader body relative to the first group of crawler traveling mechanisms. The second set of tracked running gear spacing is even smaller.

Embodiment 3

[0052] In the third embodiment, the dislocation arrangement structure is, such as Figure 9 As shown, the second group of crawler running mechanisms is arranged at a position away from the inner side of the roadheader body relative to the first group of crawler running mechanisms. The second set of crawlers is spaced a little wider.

[0053] Multiple sets of crawler traveling mechanisms are arranged in dislocation to meet the working requirements of the roadheader under different working conditions. Make the roadheader more adaptable.

[0054] Further preferably, the first left crawler running mechanism 4 has the same width as the second left crawler running mechanism 5; the first right crawler running mechanism 6 has the same width as the second right crawler running mechanism 7 (not shown in the figure) out); to make the roadheader more practical for its different working environments.

[0055] As another option, the first left crawler running mechanism 4 is different in ...

Abstract

The invention relates to the technical field of coal mine engineering machinery, in particular to a heading machine. The heading machine comprises a heading machine body, wherein at least two groups of crawler belt traveling mechanisms are installed on the heading machine body. By arranging a plurality of groups of crawler belt traveling mechanisms, the ground pressure of the whole heading machine can be reduced, and a plurality of crawler belt traveling mechanisms are arranged at the front part and the rear part of the heading machine body, so that the center of gravity of the whole machine is moved backwards, so as to prevent the machine body from tilting backwards when traveling downhill on a steep slope, and the plurality of traveling mechanisms can improve the adhesive force between the whole machine and floor boards to solve the problem of slipping and improve the drive capability of the whole machine; and by arranging a plurality of crawler belt traveling mechanisms, the problem that the whole machine fails to move due to the fault of one group of crawler belt traveling mechanisms can be prevented.

Description

technical field [0001] The invention relates to the technical field of coal mine engineering machinery, in particular to a roadheader. Background technique [0002] At present, roadheader is a kind of mining mechanical equipment used for coal mine roadway excavation. It is mainly composed of mechanical parts such as cutting part, shoveling part, main body part, walking part, rear support part and first conveyor, such as figure 1 As shown, the whole equipment also includes hydraulic system and electrical system. Its basic working principle is: the cutting mechanism cuts and shapes the section rock of the roadway through the cutting head rotating at the front, and transfers the cut rock material to the scraper conveyor in the middle of the fuselage through the rake claws on the loading mechanism to transport it to the equipment of the rear. The traveling mechanism adopts crawler type. At present, most roadheaders adopt one set (two) of crawler traveling mechanisms, which ar...
