The brake handle hydraulic driving system comprises a brake oil cylinder, an emergency oil cylinder, a brake adjusting valve set, a safety valve set and a hydraulic pump. The fixed end of the brake oil cylinder is connected with a piston rod of the emergency oil cylinder, and the piston rod of the brake oil cylinder is hinged to the brake handle. The liquid discharging end of the hydraulic pump is communicated with the emergency oil cylinder through a safety valve set, the liquid discharging end of the hydraulic pump is communicated with the brake oil cylinder through the safety valve set and a brake adjusting valve set, and the speed of a roller of the well drilling winch can be adjusted through cooperation of the safety valve set and the brake adjusting valve set. The hydraulic system drives the piston rods of the emergency oil cylinder and the brake oil cylinder to control the deflection angle of the brake handle so as to adjust the braking force applied to the roller of the drilling brake, so that the speed of the roller of the drilling brake is adjusted, and an operator can control the rotating speed of the roller of the drilling brake only through the operation table; and the labor capacity of operators is reduced.
本发明涉及一种用于钻机绞车的刹把液压驱动系统,包括制动油缸、应急油缸、制动调节阀组、安全阀组和液压泵;制动油缸的固定端与应急油缸的活塞杆连接,制动油缸的活塞杆与刹把铰接;液压泵的排液端通过安全阀组与应急油缸连通,液压泵的排液端通过安全阀组和制动调节阀组与所述制动油缸连通,通过安全阀组和制动调节阀组的配合,能够对钻井绞车的滚筒速度进行调整。本发明通过液压系统驱动应急油缸和制动油缸的活塞杆控制刹把偏转角度,以调整施加在钻井刹车的滚筒上的制动力,从而对钻井刹车的滚筒的速度进行调整,操作人员只需通过操作台即可控制钻井刹车的滚筒的转速,减轻操作人员的劳动量。
