Multi-point driving electric traction coal mining machine

Abstract

The invention discloses a multi-point driving electric traction coal mining machine which comprises a left cutting part, an electric control cabinet and a right cutting part, wherein a left traction part is arranged between the left cutting part and the electric control cabinet; a right traction part is arranged between the right cutting part and the electric control cabinet; the left traction part comprises a first fixed box and a second fixed box; the right end of the second fixed box is connected with the electric control cabinet; the left end of the second fixed box is connected with the right end of the first fixed box; the bottom of the second fixed box is connected with a second travelling box; the left end of the first fixed box is connected with the left cutting part; the bottom of the first fixed box is connected with a first travelling box; the right traction part comprises a third fixed box; the left end of the third fixed box is connected with the electric control cabinet; the right end of the third fixed box is connected with the right cutting part; the bottom of the third fixed box is connected with a third travelling box; and the third fixed box and the first fixed box have the same structures and are arranged in a symmetrical way. The coal mining machine is driven by a plurality of points at the same time, meets the mining demands of a down-hole steeply inclined coal seam, and improves the mining efficiency of the down-hole steeply inclined coal seam.

Description

technical field [0001] The invention belongs to the technical field of mining machinery and equipment, in particular to a drum-type electric traction shearer suitable for mining steeply inclined coal seams in coal mines. Background technique [0002] Drum-type electric traction shearers are generally used for mining steeply inclined coal seams in coal mines. The existing drum-type electric traction shearer is usually provided with a traction section on both sides of the middle box, and each traction section is provided with a motor, which ensures the normal running of the shearer through the motor drive. However, considering that the geological structure of our country is relatively complex, the mining of steeply inclined coal seams is relatively difficult, the power of the traction part driven by a single motor is insufficient, it is difficult to realize mechanization, the risk factor is large, the mining efficiency is low, and the working environment is harsh. Many steeply...
