Follow-up pipeline groove

Abstract

The invention provides a follow-up pipeline groove, and relates to the technical field of auxiliary equipment of drill rigs. The follow-up pipeline groove mainly comprises a high-position pipeline groove, a middle-position pipeline groove and a low-position pipeline groove. Guardrails are arranged on the high-position pipeline groove, one end of the high-position pipeline groove is hinged to a top layer of a drill floor, the other end of the high-position pipeline groove is hinged to the middle-position pipeline groove, the front end of the low-position pipeline groove is connected with a base of the drill floor by an adjustable telescopic draw bar, the other end of the middle-position pipeline groove is connected onto the low-position pipeline groove in a hinged manner and is close to the telescopic draw bar, rollers are arranged on the lower portion of the low-position pipeline groove, and a transfer case is arranged at the end, which is far away from the telescopic draw bar, of the low-position pipeline groove. The follow-up pipeline groove has the advantages that when the follow-up pipeline groove is mounted at a low position, the high-position pipeline groove is hinged to the top layer of the drill floor by the aid of an operation cylinder without being hoisted by a crane, and the length of the telescopic draw bar can be adjusted, so that a folding angle of the follow-up pipeline groove can be controlled, and the follow-up pipeline groove is applicable to different types of drill rigs provided with drill floors with different heights; the transfer case is mounted on the low-position pipeline groove, is convenient to operate and is safe and reliable, and the transfer case and the follow-up pipeline groove can form an integral transport unit.

Description

technical field [0001] The invention relates to a pipeline trough of an electric drilling rig for an oil cluster well, in particular to a follow-up pipeline trough. Background technique [0002] The top floor of the cluster well electric drilling rig used in the oil drilling field is high from the ground, generally ranging from 6 meters to 11 meters depending on the model of the drilling rig, so the power supply cables required for various equipment on the top floor of the drill floor, Water supply and gas supply pipelines must be able to be laid from the ground to the top of the drill floor, and the cables and water and gas pipelines are required to be able to move with the drilling rig as a whole. [0003] There are currently two types of existing solutions. One is to install a simple cable bracket between the top layer of the drill floor and the base. Every time the bracket is disassembled and relocated, the bracket, cables, and water and gas pipelines must be fixed and ...

Problems solved by technology

[0003] There are currently two types of existing solutions. One is to install a simple cable bracket between the top layer of the drill floor and the base. Every time the bracket is disassembled and relocated, the bracket, cables, and water and gas pipelines must be fixed and disassembled repeatedly, resulting in a long cycle and heavy workload for the drilling rig

[0004] The other is the special folding pipeline trough, where cables and water and gas pipelines are installed in the pipeline trough at a low position, and can be lifted up with the drilling rig as a whole. A transfer box is installed on the pipeline trough, but because the size of each part of this kind of pipeline trough is fixed, each drilling rig must be tailor-made for each type of rig, and the versatility is not strong, and some transfer boxes are installed on the uppermost pipeline trough. High altitude operation, high risk
