Embodiment Construction

[0015] The present invention will be further explained below in conjunction with the accompanying drawings.

[0016] like Figures 1 to 3 As shown, the double-motor driven traction section coal shearer of the present invention includes a left cutting section 1 , a left traction section, a middle box 3 , a right traction section and a right cutting section 5 .

[0017] The left traction part and the right traction part are respectively arranged on the left and right sides of the middle box 3, the left traction part comprises a left fixed box 2-1 and a left travel box 2-2, and the right traction part comprises a right fixed box 4-1 And right walk box 4-2. Both the left end of the left fixed box 2-1 and the right end of the left cutting part 1 and the right end of the right fixed box 4-1 and the left end of the right cutting part 5 are hinged. Between the bottom of the left fixed box 2-1 and the upper end of the left traveling box 2-2, between the bottom of the right fixed box ...

Abstract

The invention discloses a coal mining machine with a double-motor-driven traction section. The traction section of the coal mining machine comprises a fixed box and travelling boxes. The fixed box comprises a fixed box housing. A first motor, a second motor, and a traction reduction gearbox are arranged in the fixed box housing. The first motor and the second motor are respectively connected with a first motor gear shaft and a second motor gear shaft. A middle gear shaft is arranged between the first motor gear shaft and the second motor gear shaft. An input shaft of the traction reduction gearbox is connected with the second motor gear shaft. An output shaft of the traction reduction gearbox is connected to a transmission mechanism of a left travelling box through a planetary gear mechanism. The right travelling box has a same structure with the left travelling box, and is symmetric with the left travelling box. According to the invention, a double-motor synchronous driving manner is adopted. With the middle gear shaft, powers of the double motors are merged, such that the traction force is relatively large. Therefore, a problem of mechanical mining of a steeply inclined seam with a working face inclination angle no larger than 60 DEG is solved, mining efficiency of underground steeply inclined seam is improved, and safe production conditions are ensured.

Description

technical field [0001] The invention relates to a drum type electric traction coal shearer, in particular to a drum type electric traction coal 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 incli...
