The hydraulic brake oil cylinder comprises an oil cylinder body, a piston and a guide screw, the piston and the guide screw are arranged in the oil cylinder body, one end of the guide screw is provided with a guide shaft, the other end of the guide screw is connected with a brake hand wheel, an oil pipe is arranged in the guide shaft, the guide screw is sleeved with the piston, and the oil pipe is connected with the brake hand wheel. A spring is arranged between the piston and the inner wall of the oil cylinder body, an emergency release oil port is formed in a cylinder cover at the front end of the oil cylinder body, and the emergency release oil port is communicated with an oil pipe. On the basis that the overall dimension and the weight of an original brake oil cylinder are not increased, the function of reducing the braking force capacity in emergency is achieved, the workload of operators in the emergency state is reduced, and the use safety of equipment is improved.

    本发明涉及一种拖缆机用液压刹车油缸,包括油缸缸体以及设置在油缸缸体内的活塞和导螺杆,所述导螺杆的一端安装有导轴,另一端连接刹车手轮,所述导轴内开有一道油管,所述活塞套在导螺杆上,在所述活塞与油缸缸体内壁之间设置有弹簧,在所述油缸缸体的前端缸盖上制有应急释放油口,所述应急释放油口与油管相连通。本发明不仅在不增加原有刹车油缸外形尺寸和重量的基础上,实现了应急降低刹车制动力能力的功能,还减少了应急状态下操作人员的工作量,提高了设备使用的安全性。
