Large-gradient drilling and tunneling machine

Abstract

The invention discloses a large-gradient drilling and tunneling machine which is provided with a cutting part, a shovel plate part and a walking part, wherein the cutting part comprises a cutting support and a cutting head mounted on the cutting support; the shovel plate part comprises a shovel plate body, and the shovel plate body comprises a main shovel plate and side shovel plates positioned on the two sides of the main shovel plate; a chute is formed in the middle-rear part of the main shovel plate, and star wheels are mounted on the side shovel plates; the walking part comprises a walking frame, a tensioning wheel, a driving wheel, a track assembly and a landing leg component, and the landing leg component is mounted on the side wall of the walking frame and can be inserted into the ground; shovel plate telescoping mechanisms which can extend to the outer sides of the side shovel plates are arranged below the side shovel plates of the shovel plate part. In the large-gradient environment, the large-gradient drilling and tunneling machine cannot slip down during tunneling operation, and fallen coal seams or ores during cutting are cleanly and thoroughly cleared up. In addition, the large-gradient drilling and tunneling machine is not influenced by the hardness of roadway rock during tunneling operation and is high in tunneling efficiency and small in equipment loss.

Description

technical field [0001] The invention relates to a rock drilling machine, in particular to a large-slope rock drilling machine. Background technique [0002] The structure of the roadheader in the prior art mainly includes a cutting part, a shoveling part, and a walking part. When the roadheader in the prior art is performing a tunneling operation, the coal and rock cut by the roadheader are often not loaded completely, and the shoveling board is not completely loaded. The coal and rocks on both sides of the body need to be cleaned by adjusting the position of the body of the roadheader or manually, which not only increases the labor intensity of the workers, reduces the loading efficiency and speed of the roadheader, but also causes waste of coal and rocks. In addition, the roadheader in the prior art has unstable brakes when it goes downhill, which is easy to cause danger; when it goes uphill, the traction force for walking is insufficient, and the whole machine may sometim...

[0002] The structure of the roadheader in the prior art mainly includes a cutting part, a shoveling part, and a walking part. When the roadheader in the prior art is performing a tunneling operation, the coal and rock cut by the roadheader are often not loaded completely, and the shoveling board is not completely loaded. The coal and rocks on both sides of the body need to be cleaned by adjusting the position of the body of the roadheader or manually, which not only increases the labor intensity of the workers, reduces the loading efficiency and speed of the roadheader, but also causes waste of coal and rocks

In addition, the roadheader in the prior art has unstable brakes when going downhill, which is easy to cause danger; when going uphill, the traction force for walking is insufficient, and the whole machine may sometimes slip or slide.
