Roadheader Cutting Section Hybrid Powertrain

Abstract

The invention discloses a hybrid power transmission system of a cutting part of a heading machine. The hybrid power transmission system comprises a cutting motor, a cutting head, a hydraulic motor and a hydraulic power system connected with the hydraulic motor, wherein the cutting motor is in transmission connection with the cutting head through a planetary reducer; the power end of the hydraulic motor is connected with the planetary reducer in a rotating speed coupling manner, or the power end of the hydraulic motor is connected with the power input shaft of the cutting head in a torque coupling manner. The power of the cutting head is provided by the cutting motor and the hydraulic motor together, and the hydraulic power system for driving a running mechanism can be used for driving the hydraulic motor, so that the power of the cutting motor can be reduced, the load of a cutting arm can be alleviated, and the power of the hydraulic power system can be fully utilized; the hydraulic system and a mechanical system share the vibratory impact caused by the work of the cutting head, so that the damage to the cutting motor due to the vibratory impact caused by the work of the cutting head can be alleviated, the service life of each component can be prolonged, and the adaptability of the cutting condition can be improved.

Description

technical field [0001] The invention relates to a transmission system, in particular to a transmission system of a cutting part of a roadheader. Background technique [0002] At present, in the mining process of coal mines, mines and engineering tunnels, most of the existing cantilever roadheaders use two high-power motors, one of which is used as the power source of the cutting part; the other is used as the power source of the traveling mechanism. [0003] Due to the working characteristics of the roadheader, it is impossible to carry out the driving process and the cutting process of the roadheader at the same time, which leads to the fact that the power of the hydraulic system of the existing roadheader traveling mechanism cannot be fully utilized during the cutting process; at the same time, due to the The cutting process is carried out according to the prescribed cutting route, so the hydraulic lifting system and the slewing system of the cutting arm will not work at t...
