Transferring device used for upper-lower catwalk of pipe rod

Abstract

The invention discloses a transferring device used for an upper-lower catwalk of a pipe rod. The transferring device comprises a catwalk support, rotating arms, a hydraulic device arranged obliquely, a front pipe rod lifting device and a rear pipe rod lifting device. The rotating arms are arranged at the two ends of the catwalk support and hinged to the two ends of the catwalk support; the hydraulic device arranged obliquely is used for driving the rotating arms to rotate; the front pipe rod lifting device comprises a top plate, a first upright hydraulic device and a second upright hydraulic device, and the first upright hydraulic device and the second upright hydraulic device are vertically arranged at the bottoms of the two ends of the top plate respectively and are used for driving the top plate to move and rotate in the vertical direction; the rear pipe rod lifting device is the same as the front pipe rod lifting device in structure. The transferring device used for the upper-lower catwalk of the pipe rod can achieve the transferring work of the pipe rod between the catwalk and a ground pipe frame automatically and easily by using a power device.

Description

technical field [0001] The invention relates to the technical field of oil drilling and workover transporting equipment, in particular to a transporting device for pipe rods going up and down catwalks. Background technique [0002] Drilling catwalk (ie, catwalk) is used for workover and drilling operations. It has a groove-like structure (ie, limit groove) and can be used to place pipes and rods (including drill pipes, drill jacks, casings, etc. tools) on the drill floor. During drilling and workover operations, pipes and rods must be transported to the catwalk before being transported from the pipe rack (that is, the ground pipe rack) to the drilling floor. [0003] However, in the process of transporting the pipes on the pipe rack to the catwalk on the drill floor, or transferring the pipes and other drilling tools in the catwalk on the drill floor to the pipe rack, the prior art relies on manual handling. . Specifically, due to the height difference between the ground ...

AI Technical Summary

Problems solved by technology

Obviously, in the process of transferring drilling tools such as pipes and rods in the catwalk on the drill floor to the pipe rack, it also takes a lot of manpower and time

[0004] In both cases, manual handling is required to realize the transfer of pipes and rods, and there are technical defects such as high labor intensity, low efficiency, improper operation, easy injury, and potential safety hazards.
