Abstract

The invention discloses a tower-type derrick lifting device and lifting method, and belongs to the field of petroleum drilling and exploitation equipment. The lifting device comprises a lifting cylinder, lifting pulleys, guiding tackles, lifting ropes, a lifting frame, hinge pins, pin punching cylinders and guide rail grooves. The lifting cylinder is connected with a derrick lifting section, the lifting pulleys are arranged at the upper ends of piston rods of the lifting cylinder, the guide rail grooves are formed in the derrick lifting section, and the guiding tackles are in sliding connection with the guide rail grooves. The guiding tackles are connected with the piston rods of the lifting cylinder, the lifting ropes are wound around the lifting pulleys, one ends of the lifting ropes areconnected with the derrick lifting section, and the other ends of the lifting ropes are connected with the lifting frame. The pin punching cylinders are arranged horizontally on a cross beam of the derrick lifting section, and the hinge pins are connected with piston rods of the pin punching cylinder. By using the tower-type derrick lifting device, a tower-type derrick is lifted in stages, the situations of working at high altitude in a traditional operation way and hoisting by using a large crane are avoided, and the safety and efficiency of derrick lifting are improved.

Description

technical field [0001] The invention belongs to the field of oil drilling equipment, in particular to a tower type derrick lifting device and a lifting method. Background technique [0002] As the main form of marine derrick, the tower derrick is usually 40~60m high, and there are two main installation methods. The first is the method of hoisting single rods one by one. During the installation process of this form, the installer needs to go to each connection joint to install and fasten the bolts. The operation process is very dangerous and the installation efficiency is extremely low. The second method divides the derrick into several sections, assembles it on the shore into a complete derrick including the crown block, and then uses a marine floating crane with sufficient hoisting capacity to hoist the derrick as a whole to the drilling platform. And in other occasions that do not have this kind of lifting capacity, a new type of derrick lifting method that is easy to op...
