The invention relates to the technical field of cranes, and discloses a crane pulley device capable of automatically supplementing oil. The crane pulley device comprises a shell, wherein a sling is arranged above the shell, a lifting hook movably connected to the lower end of the shell, a guide wheel is arranged inside the shell, a main shaft is coupled to the center of the guide wheel, a lubricating bin is arranged on the front side of the shell, an oil injection wheel is coupled to the front part of the main shaft, a crank piston is arranged in the oil injection wheel, an oil outlet nozzle is arranged on the oil injection wheel close to the axis, a right gear of the oil injection wheel is in meshed connection with a pointer wheel, a pointer is arranged on the front side of the pointer wheel, and a dial plate is arranged on the front side of the shell corresponding to the pointer. According to the crane pulley device capable of automatically supplementing oil, when a pulley works, a vibration block vibrates due to insufficient lubrication, the vibration block is driven to drive a lubricating bin shell to vibrate, a ratchet wheel is shifted by a pawl, then the oil injection wheel is driven to rotate for oil injection, harmful vibration mechanical energy in work is recycled without the help of external energy, and the oil injection device is driven to inject oil, and the service life of the pulley is prolonged.
本发明涉及起重机技术领域,且公开了一种可自动补油的起重机滑车装置,包括壳体,壳体的上方设置有吊索,壳体的下端活动连接有吊钩,壳体的内部设置有导轮,导轮的中心耦接主轴,壳体的前侧设置有润滑仓,主轴的前部耦接有注油轮,注油轮内设置有曲杆活塞,注油轮靠近轴心处设置有出油嘴注油轮的右侧齿轮啮合连接有指针轮,指针轮的前侧设置有指示针,壳体前侧对应指示针位置设置有表盘。该可自动补油的起重机滑车装置,通过滑车工作时,振动块因润滑不足产生振动,带动振动块带动润滑仓外壳振动,使棘爪拨动棘轮,继而带动注油轮转动注油,实现不借助外接能源,将工作中有害的振动机械能回收,驱动注油装置注油,延长滑车寿命。
