Abstract

The invention relates to the technical field of oil drilling and workover rigs, in particular to a pipe transfer system, which includes a frame and a transfer device, the transfer device is arranged on the frame, and the transfer device includes a chain and a main sprocket and the secondary sprocket, the chain is provided with a clamping block adapted to the rod body, the main sprocket is connected with a reversing device, and the secondary sprocket is connected with a mounting mechanism, which is simple in structure and easy to use, so that the rod body There is no need for human participation in the horizontal transfer process, and full automation is realized, and the movement track is controllable, which effectively avoids equipment damage or personnel injury caused by the rod body falling off, improves the efficiency of the rod body processing process and the safety of the transfer process, and at the same time, can The transmission direction of the chain is converted by the reversing device, and the transmission distance of the chain is adjusted by the installation mechanism, so that the chain conveyor can be used flexibly under different working conditions of drilling and workover, and has good adaptability.

Description

technical field [0001] The invention relates to the technical field of oil drilling and workover machines, in particular to a pipe transfer system. Background technique [0002] In the process of oil and gas development, long rod-shaped pipes or drilling tools for drilling and workover (not limited to drill pipe, drill collar, casing, tubing, and drill pipe stand, drill collar stand, casing stand, tubing stand, etc.) Well pipes) are long in length and heavy in weight. Taking drill pipes as an example, they are usually transported to the well site by a trailer and then stacked on the drill rack. When used, they need to be transported to the On the mechanical catwalk or power catwalk, the auxiliary pneumatic winch, through manual operation and the cooperation of the drill floor auxiliary winch, changes the drill pipe from the horizontal state to the vertical state, and then transfers it to the drill floor. After the use of the drill pipe, the same The steps are reversed to re...
