A foldable power catwalk

Abstract

The invention belongs to the technical field of power catwalk equipment on oilfield drilling sites, and relates to a foldable power catwalk, comprising 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 frame is connected with the rear end of the extension frame, more than two sets of power pipe racks are installed on both sides of the catwalk main frame, one end of the power pipe rack is 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 lower end of the ramp is provided with a traction winch, the upper end of the folding ramp is fixedly connected to the upper end of the drilling platform, and a folding transfer arm is nested inside the upper end of the main frame of the catwalk. The power catwalk and the folding transfer arm provide convenience for the transportation of the power catwalk. At the same time, the displacement compensation structure of the power pipe frame protects the ground level, and the folding ramp can be applied to the drilling floor of various heights, ensuring the working stability of the power catwalk. practicality.

Description

Technical field: [0001] The invention belongs to the technical field of power catwalk equipment on oilfield drilling sites, and relates to a power catwalk that can be folded and is easily transported, in particular to a foldable power catwalk. Simple operation, practical and reliable. Background technique: [0002] In the process of oilfield drilling, it is necessary to transport drill pipes, drill collars and pipes from the ground to the drilling floor through the power catwalk. The ramp, as the main structural component of the power catwalk, plays an important role in connecting and supporting, and at the same time as a transfer The track of the arm movement carries and guides the movement of the transfer arm. The transfer arm of the conventional power catwalk is an integrated welding type, with a long length. The ramp structure adopts the overall frame mode, and the length is long, which is an ultra-long part. The base structure is a welded integrated type, and the lengt...
