Shearer Product Overview

Shearer uses and scope of use

2.4m ,倾角小于 30 ° , 煤层中硬或中硬以下 , 并含有少量夹石的长壁式采煤工作面。 Shearer is suitable for long-wall coal mining face with coal mining height of 1.4 2.4m , inclination angle less than 30 ° , medium hard or below medium hard , and containing a small amount of rock. The electrical equipment of this coal mining machine meets the requirements of mine explosion-proof regulations, and can be used in mines in which methane, coal dust, hydrogen sulfide, carbon dioxide, etc. in the surrounding air do not exceed the safety content specified in the "Coal Safety Regulations".

Shearer can be matched with hydraulic support and working surface scraper conveyor, which can realize comprehensive mechanized coal mining in the coal mining face. In addition, because the body of the shearer is short and narrow, it can also be used with a single hydraulic prop. The metal hinged top beam is matched with the working surface conveyor to realize the high-end general mining mechanized coal mining on the coal mining working face.

Composition and characteristics of shearer

The coal winning machine is mainly composed of a motor, a hydraulic transmission unit, a traction transmission unit, a cutting unit, a bottom bracket, a height-adjusting oil cylinder, and a cable tow device.

Compared with the same type of unit, the shearer has the following characteristics.

) 机身长度短而窄,适应范围广; ( 1 ) Short and narrow fuselage length, wide range of application;

) 主要元部件均按 250KW 电动机功率设计,强度裕度大,可靠性高,可更换电动机即可成为 250KW 功率的采煤机 ( 2 ) The main components are designed according to the 250KW motor power, with large strength margin and high reliability. The motor can be replaced with a 250KW power shearer.

) 滚筒截割转矩较大,能适应截割硬煤; ( 3 ) The cutting torque of the drum is large, which can adapt to cutting hard coal;

) 采用液压无级调速。 ( 4 ) Hydraulic stepless speed regulation. Gear-pin row type chainless traction, stable work and high traction. 350KN The traction transmission is set at both ends of the fuselage. Due to the use of a double traction mechanism, the specific pressure of the transmission gear to the pin row is reduced, the service life of the pin row is increased, and the traction force of the whole machine is greatly improved .

) 系统简单可靠,控制手把集中,操作和维修方便; ( 5 ) The system is simple and reliable, the control handle is centralized, and the operation and maintenance are convenient;

) 油马达和制动器布置在牵引传动部靠老塘侧,便于井下更换,且油质不易污染; ( 6 ) The oil motor and brake are arranged near the old pond side of the traction drive, which is convenient for underground replacement, and the oil quality is not easily polluted;

) 采用内外喷雾冷却系统,改善工作面环境,提高采煤机工作的可靠性。 ( 7 ) Adopting internal and external spray cooling systems to improve the working surface environment and the reliability of the coal mining machine.

) 采用电缆拖移装置,保护电缆和水管,减轻工人劳动强度; ( 8 ) adopt cable tow device to protect cables and water pipes and reduce labor intensity of workers;

) 供电电压有 660V 1140V 两种,以适应不同用户的需要。 ( 9 ) There are two kinds of power supply voltages, 660V and 1140V , to meet the needs of different users.

)采煤机电控型式采用动力载波控制 , 能减少控制芯线 , 取消多芯电缆 , 并能完成多种动作功能 , 保证采煤机安全可靠运行。 ( 10 ) The electromechanical control type of the coal mining adopts power carrier control , which can reduce the control core wire , eliminate the multi-core cable , and can complete a variety of action functions to ensure the safe and reliable operation of the coal mining machine.
