安装在斜巷内的气动吊梁是防止和控制跑车事故的一种安全设施。气动吊梁一端固定在巷道顶部.另一端是以高压风为动力,在气缸和控制阀的作用下.通过钢丝绳的牵引,实现升起和落下,即敞开和关闭矿车的通道。气动吊梁装置可分为5个部分:挡车部分(吊梁部分)、气缸部分(动力部分)、控制部分(气控阀部分)、牵引部分(钢丝绳部分)、固定件。目前,里彦煤矿使用的气动吊梁装置,挡车部分为工字钢梯形梁体,4500mm×600mm,重300kg;气缸
Pneumatic hanging beam installed in inclined lane is a kind of safety equipment to prevent and control sports car accident. One end of the pneumatic crane beam is fixed on the top of the roadway and the other end is powered by high-pressure wind, which is under the action of air cylinder and control valve and is hoisted and dropped by towing of the steel wire rope. Pneumatic lifting beam device can be divided into five parts: the car part (crane beam part), the cylinder part (power part), the control part (air control valve part), the traction part (rope part), the fixed parts. At present, the pneumatic lifting beam device used in Liyan Coal Mine, the block part of the I-beam trapezoidal beam body, 4500mm × 600mm, weight 300kg; cylinder
