The invention discloses a double-acting band-type brake, and relates to the technical field of metallurgical production equipment. Comprising two band-type brake bodies, a band-type brake assembly used for holding or releasing a brake wheel, a lever hinged to one band-type brake body and hinged to the other band-type brake body through a connecting rod, a brake spring hinged to the same side of the lever, an electric pusher and a single-action air cylinder, and torque generated by the brake spring enables the two band-type brake bodies to hold the brake wheel tightly. The electric pusher and the single-acting cylinder can independently open the two band-type brake bodies, the thrust rod extends out when the electric pusher is in a power-on state, the lever is pushed to overcome the spring force of the brake spring, and the brake wheel is loosened; a piston rod extends out when the single-acting cylinder is in a ventilation state, the lever is pushed to overcome spring force of the brake spring, and the brake wheel is loosened. The double-acting band-type brake can realize an electric driving mode and a pneumatic driving mode, so that the function of lifting an oxygen lance by an emergency pneumatic motor is realized, and major potential safety hazards such as water entering a furnace are effectively avoided.
本发明公开了一种双作用抱闸,涉及冶金生产设备技术领域,包括具有二抱闸本体、用以抱紧或者松开闸轮的抱闸组件、与其中一抱闸本体铰接且与另一抱闸本体通过连杆铰接的杠杆、与杠杆的同侧均铰接的制动弹簧、电力推动器以及单作用气缸,制动弹簧产生的力矩使二抱闸本体抱紧闸轮,电力推动器和单作用气缸能够独立打开二抱闸本体,电力推动器在通电状态下推力杆伸出,推动杠杆克服制动弹簧的弹簧力,实现松开闸轮;单作用气缸在通气状态下活塞杆伸出,推动杠杆克服制动弹簧的弹簧力,实现松开闸轮。该双作用抱闸能够实现电力、气力两种驱动模式,从而实现应急气动马达提升氧枪的功能,有效杜绝炉内进水等重大安全隐患的发生。
