Foldable power catwalk

Abstract

The invention belongs to the technical field of oil field drilling field power catwalk equipment, and relates to a foldable power catwalk. The catwalk comprises a catwalk main frame, a power pipe frame, a folding ramp, a folding transfer arm, a traction winch and an extension frame. The front end of the catwalk main frame is connected with the rear end of the extending frame, more than two sets ofpower pipe frames are installed on the two sides of the catwalk main frame, one ends of the power pipe frames are hinged to the catwalk main frame, and the rear end of the catwalk main frame is hinged to the lower end of the folding ramp. The upper end of the folding ramp is fixedly connected with the upper end of the drilling platform, and the folding transfer arm is nested in the upper end of the catwalk main frame. According to the power catwalk, the power pipe frame, the folding ramp and the folding transfer arm which are of a foldable structure are adopted, convenience is provided for power catwalk transportation, meanwhile, the power pipe frame displacement compensation structure protects the ground to be flat, the folding ramp can be applied to drill floor surfaces of various heights, and the working stability and practicability of the power catwalk are guaranteed.

Description

Technical field: [0001] The invention belongs to the technical field of power catwalk equipment at the oilfield drilling site, and relates to a foldable and convenient transshipment power catwalk, in particular to a foldable power catwalk. Simple operation, practical and reliable. Background technique: [0002] During oil field drilling, drill pipes, drill collars and pipes need to be transported from the ground to the drill floor through the power catwalk. The track of the arm movement carries and guides the movement of the transfer arm. The transfer arm of the conventional power catwalk is one-piece welded type, and the length is longer. The ramp structure adopts the overall frame mode, which is longer and belongs to the super-long type. Parts, which cause the entire power catwalk to be super long, it is inconvenient to use a general trailer for transportation, and special transport vehicles are required for transportation; generally, the catwalk is basically equipped wi...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art, aiming at the long overall transportation length of the existing power catwalk, the high cost of transshipment, the displacement of the power pipe frame during the working process, and the dragging and wear of the ground and the generation of pits that affect the normal operation of the equipment Insufficient operation, etc., under the condition of ensuring the convenience of use, design a foldable power catwalk
