Problems solved by technology

At this stage, with the increasing power of rock roadheading machines, when cutting high-hardness rocks, the force on the picks at the top of the cutting head increases, and the cutting mechanism is subjected to severe impacts or the picks are severely worn, which makes the roadheader reliable. The reliability is seriously reduced, and workers are required to frequently replace the picks and related components, which seriously restricts the cost of excavation, and at the same time seriously reduces the efficiency of rock roadway excavation, which contradicts the requirements of rapid roadway excavation

Abstract

A novel flexible transmission heading machine cutting part comprises a cutting head, a planetary gear reducer, a flexible transmission mechanism and a cutting motor shaft, wherein the cutting head is arranged at the front end of the planetary gear reducer, the planetary gear reducer is connected with the flexible transmission mechanism through a flexible transmission shaft, the other end of the flexible transmission mechanism is connected with the cutting motor shaft, the flexible transmission shaft adopts a pair of bearings supporting the inner side of a planetary carrier, and a sun gear is fixed at the front end of the flexible transmission shaft; the flexible transmission shaft is provided with two aluminum discs distributed in parallel; an end cover connected with the rear end of the flexible transmission shaft is connected with a motor coupling through a bolt, and the cutting motor input shaft is fixed in the motor coupling and is mounted in a cutting cantilever. Compared with the prior art, the novel flexible transmission heading machine cutting part provided by the invention comprises the novel flexible transmission mechanism, so that soft start of a heading motor can be realized, and the impact vibration caused when the heading machine cutting part starts can be reduced.

Description

technical field [0001] The invention relates to a tunneling machine, in particular to a novel cutting part of a tunneling machine with flexible transmission. Background technique [0002] At present, my country has become the world's largest roadheader manufacturing base and application market. With the high-speed growth of domestic urban road transportation, railways, highways, water conservancy, municipal engineering and other construction projects, my country's excavation machinery has also ushered in rapid development. my country's excavation machinery industry has become a key supporting development industry for domestic high-end equipment manufacturing and strategic emerging industries. [0003] The roadheader is the key equipment for the rapid excavation of modern roadways. With the mining of rock, there are more and more hard rock excavation tasks. However, the working conditions of the hard rock roadheader are harsh. The cutting mechanism is the core component of t...
