Cantilever type heading machine for tunnel excavation

Abstract

The invention relates to the technical field of heading machines and discloses a cantilever type heading machine for tunnel excavation. The heading machine comprises a heading machine body, the left side of the upper surface of the heading machine body is fixedly connected with a box, the bottom of the heading machine body is fixedly connected with a driving supporting device, the outer surface ofthe driving supporting device is in transmission connection with a crawler belt, the left side of the box is movably connected with a supporting arm, the left end of the supporting arm is movably sleeved with a transmission arm, and the left end of the transmission arm is clamped with a heading head through a fastening device. According to the cantilever type heading machine for tunnel excavation, an included angle of 90 degrees is formed between two dust removal devices and a conveying tube, so that a proper amount of dustproof foam is conveniently sprayed on the position of a heading end for exploitation, the dustproof foam plays a role in solidifying dust, the spraying coverage rate is high, the flying degree of dust in a tunnel is reduced, the definition of the visual field of a useris improved, meanwhile, the dustproof foam cannot melt geology which is melted immediately when meeting water and is extremely easy to disintegrate, and the user can conveniently excavate.

Description

technical field [0001] The invention relates to the technical field of roadheaders, in particular to a cantilever type roadheader for tunnel excavation. Background technique [0002] More and more engineering projects are going abroad. The geological conditions in different regions abroad are quite different from those in China, and the requirements for lining support of tunnel engineering are also different. The cantilever roadheader is a kind that can realize cutting, loading and transportation , Self-propelled combined unit. [0003] With the rapid development of mining work and tunnel use, the speed requirements of the cantilever roadheader are getting higher and higher. When encountering some areas with extremely special lithology, mudstone and argillaceous sandstone contain The stability of the surrounding rock in the state is acceptable, but it melts when exposed to water and is easily disintegrated. For this reason, we provide a cantilever type roadheader for tunnel...
