Abstract

The invention relates to the technical field of coal mining equipment, and particularly discloses a powerful pin row type traction driving system of a coal mining machine. The powerful pin row type traction driving system comprises a coal mining machine body, a traction box is arranged at the bottom of the coal mining machine body, a rack rail wheel is rotationally connected into the traction box, a pin rail meshed with the rack rail wheel is arranged under the coal mining machine body, a contact switch capable of being matched with the pin rail is arranged at each tooth root of the rack rail wheel, the contact switches are in a closed state in a natural state, a buzzer is arranged in the traction box, and the contact switches are connected with the buzzer in parallel. The invention aims to provide the powerful pin row type traction driving system of the coal mining machine to solve the technical problem that coal accumulated at the tooth root of the rack rail wheel is difficult to observe.

Description

technical field [0001] The invention relates to the technical field of coal mining equipment, and specifically discloses a powerful pin row type traction driving system for a coal mining machine. Background technique [0002] my country is the largest coal producer in the world. With mining year by year, coal resources are gradually declining. Therefore, for the sustainable development of coal production, there are a large number of coal pillars and corner coal that urgently need to be recycled. Usually need to use shearer to mine. [0003] The coal shearer is a large and complex system integrating machinery, electricity and hydraulic pressure. It is generally composed of a traction unit, a cutting unit, a travel box, a rocker arm and an electric control unit. The bottom of the travel box is equipped with a guide shoe and a support slide. The traction part mainly includes the traction motor and the traction transmission system. The main working principle is to transmit the ...
