Petroleum drilling machine pipe transferring equipment

Abstract

The invention discloses petroleum drilling machine pipe transferring equipment which comprises a catwalk main body, a catwalk vehicle, a ramp and one or more pipe sorting mechanism sets which is / are arranged on one side or the two sides of the catwalk main body and located between a pipe arrangement rack and the catwalk main body. Each pipe sorting mechanism set comprises a base, a bracket, a bracket lifting part, a sorting top plate and a top plate lifting part, wherein the side, close to the catwalk main body, of the bracket is hinged to the base; the bracket lifting part is arranged under the bracket, located on the side, away from the catwalk main body, of the bracket, and used for jacking up the side, away from the catwalk main body, of the bracket; the sorting top plate is arranged on the side, tightly close to the catwalk main body, of the bracket, and the upper surface of the sorting top plate is a slope facing the catwalk main body; and the top plate lifting part is arranged under the sorting top plate and is used for jacking up the sorting top plate to enable the slope of the sorting top plate to be higher than the upper surface of the bracket and the upper surface of the catwalk main body. By adoption of the petroleum drilling machine pipe transferring equipment, the function that pipes are automatically transferred to the catwalk main body from the pipe arrangement rack is achieved, accordingly the manual labor intensity is greatly relieved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of oil drilling equipment, in particular to an oil drilling rig pipe tool transfer equipment. Background technique [0002] The drilling operation is to drill the drilling rig pipe into the surface through the drilling equipment. After the drilling is completed, the drilling rig pipe is taken out. The number of pipes required for drilling is large, generally hundreds or thousands, which need to be continuously transferred between the drilling floor and the pipe discharge rack, and the workload is large. [0003] An existing device for transferring pipes between a drilling floor and a pipe discharge rack mainly includes a ramp, a catwalk and a catwalk support frame; The front end of the track is docked; the cat track is provided with a cat track car that slides with the cat track, and the cat track car can move back and forth on the cat track to transfer pipes on the cat track; there is a ramp car on the ram...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned device can realize the transfer of pipes between the drill floor and the pipe discharge rack, the process of transferring the pipe from the pipe discharge rack to the catwalk and fixing one end of the pipe on the catwalk cart is all manually operated , It consumes a lot of manpower, which affects the work efficiency; in addition, the surface of the catwalk is flat, and the pipe is prone to deflection when it is transferred on the catwalk, and cannot be transferred along the transfer direction of the catwalk, which is not conducive to subsequent transfer operations. Especially when transferring from the catwalk to the ramp, due to the deflection of the pipe, the end of the pipe is not easy to transfer to the ramp, the transfer is not smooth, and there may even be safety problems such as pipe jamming and falling

In addition, the executive mechanism for the transfer and transition of the pipe between the ramp and the catwalk is complex and has a high failure rate

[0005] To sum up, how to solve the problem of high manual labor intensity in the process of transferring pipes from the pipe discharge rack to the catwalk has become an urgent problem to be solved by those skilled in the art
