The invention provides a soil box anti-rotation device and a crane provided with the same. The soil box anti-rotation device is arranged on a cargo boom of the crane and comprises a fixed guide wheel, a pull rope, a balancing weight and at least one fixed pulley, the fixed guide wheel is fixedly connected with the lower end of the cargo boom, and the fixed pulley is fixedly connected with the upper end of the cargo boom; and one end of the pull rope is fixedly connected with a soil box, the end, away from the soil box, of the pull rope sequentially winds around the fixed guide wheel and the fixed pulley, then the end of the pull rope is fixedly connected with the balancing weight, and a certain included angle is formed between the pull rope between the fixed guide wheel and the soil box and the hoisting direction of the crane. According to the soil box anti-rotation device, lifting ropes of two hooks of the crane can be prevented from being mutually wound, and the soil slag lifting efficiency is improved.
本发明提供了一种土箱防旋转装置设有该装置的起重机,土箱防旋转装置设于起重机的起重臂上,包括固定导向轮、拉绳、配重块和至少一个定滑轮,所述固定导向轮与起重臂的下端固定连接,所述定滑轮与起重臂的上端固定连接,所述拉绳的一端与土箱固定连接,所述拉绳远离土箱的一端依次绕经所述固定导向轮和所述定滑轮后,端部与所述配重块固定连接,且所述固定导向轮和土箱之间的拉绳与起重机起吊方向具有一定夹角。本发明能够避免起重机两个挂钩的吊绳相互缠绕,提高土渣吊运效率。
