The invention relates to the field of monorail hoist equipment, and discloses a monorail hoist brake which comprises a machine frame, a swing arm and a brake flashboard are arranged on the two sides of the machine frame respectively, an air cylinder barrel is arranged at the bottom of the machine frame, and a brake piston and a brake spring which are fixedly connected with two push shafts respectively are movably sleeved with the air cylinder barrel. A standby push shaft is arranged in the air cylinder barrel, and the other end of the standby push shaft is fixedly connected with a standby piston. By additionally arranging the standby push shaft and the standby piston in the air cylinder barrel and matching with the air guide structure design of the air guide header pipe, braking is carried out in the mode that pressurization air injection overcomes the elastic force of the brake spring, and therefore when the brake piston leaks, the standby piston is used for pushing the standby push shaft and the brake piston to move to carry out emergency braking; and braking is canceled by using the elastic force of the spring, so that the problem that the spring easily generates elastic fatigue due to the fact that the monorail hoist brake spring is always in a high-strength compression state is avoided.
本发明涉及单轨吊车设备领域,且公开了一种单轨吊车制动器,包括机架,机架的两侧分别设有摆臂、制动闸板,所述机架的底部设有气缸筒,所述气缸筒内活动套装有分别与两个推轴固定连接的制动活塞、制动弹簧,所述气缸筒的内部设有备用推轴,备用推轴的另一端固定连接有备用活塞。通过气缸筒内备用推轴、备用活塞的结构增设,配合导气总管的导气结构设计,利用加压注气克服制动弹簧的弹力方式进行制动,从而能够在制动活塞出现泄漏问题时,利用备用活塞推动备用推轴和制动活塞移动进行紧急制动,并且利用弹簧弹力取消制动,避免单轨吊车制动器弹簧始终处于高强度的压缩状态,使得弹簧容易产生弹性疲劳问题。
