The invention discloses a cylinder sleeve hoisting tool of drilling pumps, and relates to the field of petroleum engineering equipment, in particular to the cylinder sleeve hoisting tool of the drilling pumps. The cylinder sleeve hoisting tool comprises an M20 nut, a hoisting body, a lining, a hoisting ring, an M20 * 70 bolt, an M20 * 110 bolt, an M8 * 40 bolt and an M8 nut. During hoisting of cylinder sleeves, the gravity center lines of the hoisting tool, the cylinder sleeves of various specifications and cylinder sleeve glands completely coincide with the center of a hoisting hole, the cylinder sleeves are hoisted very stably, the cylinder sleeve hoisting tool, cylinder sleeve pressing plates and the cylinder sleeves are fixed together through the M20 * 110 bolt, hoisting is safe and reliable, the cylinder sleeve hoisting work can be completed by one person, the cylinder sleeve pressing plates of the drilling pumps are fully utilized by the cylinder sleeve hoisting tool, standard parts including the M20 nut, the M20 * 70 bolt, the M20 * 70 bolt, the M20 * 110 bolt, the M8 * 40 bolt and the M8 nut are adopted, only three small parts including the hoisting body, the lining and the hoisting ring need to be manufactured, welding is not needed, the parts cannot deform due to welding, and the manufacturing cost is very low.
本发明公开了一种钻井泵的缸套吊装工具,涉及石油工程设备领域,具体涉及一种钻井泵的缸套吊装工具,包括M20螺母、吊装体、衬套、吊环、M20×70螺栓、M20×110螺栓、M8×40螺栓、M8螺母,吊装缸套时,吊装工具、各种规格的缸套、缸套压盖的重心线与吊装孔中心完全重合,吊装缸套非常平稳,缸套吊装工具通过M20×110螺栓和缸套压板、缸套固定在一起,吊装时安全可靠,一个人便可以完成吊装缸套的工作,缸套吊装工具充分利用钻井泵自身的缸套压板,采用标准零件M20螺母、M20×70螺栓、M20×70螺栓、M20×110螺栓、M8×40螺栓、M8螺母,只需作三个小零件吊装体、衬套、吊环,不用焊接,零件不会因焊接变形,制造成本非常低。
