The invention relates to the technical field of hydraulic tension oil cylinders, in particular to a multistage piston hydraulic tension oil cylinder which comprises a cylinder body, a piston is slidably connected into the cylinder body, a rod piece is fixedly connected to the lower end of the piston, a lower base is fixedly connected to the lower end of the rod piece, and an upper base is fixedly connected to the upper end of the cylinder body. A first liquid pipe is fixedly connected to the position, close to the lower end, of the front end of the cylinder body, a second liquid pipe is fixedly connected to the position, close to the upper end, of the front end of the cylinder body, an anti-falling mechanism is arranged at the lower end of the upper base, an annular shell is fixedly connected to the lower end of the upper base, and arc-shaped plates are fixedly connected to the two sides of the upper end of the lower base. And notches are formed in the opposite sides of the two arc-shaped plates, so that a rod piece can be fixed in time when the device has a falling emergency situation, a carried object is prevented from falling quickly during working, the safety performance of the device is improved, and the device has higher practicability.

    本发明涉及液压拉力油缸技术领域,具体为一种多级活塞液压拉力油缸,包括缸体,所述缸体的内部滑动连接有活塞,所述活塞的下端固定连接有杆件,所述杆件的下端固定连接有下底座,所述缸体的上端固定连接有上底座,所述缸体的前端靠近下端的位置固定连接有第一液管,所述缸体的前端靠近上端的位置固定连接有第二液管,所述上底座的下端设有防坠机构,所述上底座的下端固定连接有环形壳,所述下底座的上端两侧均固定连接有弧形板,两个所述弧形板的相背一侧均开设有槽口,这样可以使该装置在发生下坠突发情况的时候,及时的将杆件进行固定,避免在工作的时候载物快速下坠,提高了该装置的安全性能,使该装置更具有实用性。
