The invention discloses a crane lifting hook convenient to disassemble. The crane lifting hook involves a lifting hook connecting frame, a hook replacement connecting plate is connected to the lower end of the lifting hook connecting frame, a detachable lifting hook body is arranged on the hook replacement connecting plate, the lifting hook body comprises a horizontal supporting shaft, a hook head is fixedly connected to the middle of the lower end of the horizontal supporting shaft, and a through groove penetrating through the upper and lower end faces is formed in the hook replacement connecting plate; the lifting hook can be replaced according to different requirements, and the lifting hook can be replaced only by jacking the hook head upwards, rotating the hook head by 90 degrees and finally moving the hook head downwards; meanwhile, a steel wire rope connected with a spring buckle is additionally arranged on the hook, the spring buckle can be opened by pulling the steel wire rope upwards, and when the steel wire rope continues to be lifted upwards, the hook can be inclined, so that the steel wire for hanging heavy objects automatically falls off, the labor intensity of people is greatly reduced, and the working efficiency is improved; and a pressure sensor in contact with the horizontal supporting shaft is arranged at the upper part of a groove, so that whether a hoisted object is overweight or not can be conveniently monitored, and the damage of a crane jib is effectively avoided.
本发明公开了一种便于拆卸的起重机用吊钩,包括吊钩连接架,吊钩连接架下端连接有换钩连接板,换钩连接板上设置有可拆卸的吊钩,吊钩包括水平支撑轴,水平支撑轴下端的中间固定连接有钩头,换钩连接板上开设有贯穿上下两端面的通槽;吊钩可以根据不同需要进行更换,更换时只要向上顶钩头,转动钩头90度,最后向下移动钩头即可;同时在挂钩上加设了与弹簧扣连接的钢丝绳,通过向上拉动钢丝绳,可以将弹簧扣打开,钢丝绳继续往上提升时,即可使挂钩倾斜,使悬吊重物的钢丝自动掉落,大大降低了人们的劳动强度,提高工作效率;通过在凹槽上部设置与水平支撑轴接触的压力传感器,可以方便的监测到所吊装物体是否超重,有效的避免了起重机吊臂的损坏。
