Hydraulic folding minor repair working platform moved along with derrick

Abstract

The invention provides a hydraulic folding minor repair working platform moved along with a derrick. The hydraulic folding minor repair working platform moved along with the derrick comprises a derrick linkage body, a hydraulic folding mechanism, an adjustment supporting mechanism and a working table facet. A positioned of the derrick linkage body is welded to a derrick stand column. Connection pieces are vertically fixed to angle iron of the derrick through bolts. A guide rail is welded to the upper connection piece and the lower connection piece. One end of a hydraulic oil cylinder of the hydraulic folding mechanism is arranged at the lower end of the guide rail through a lug base, and the other end of the hydraulic oil cylinder is connected with a connection rod. A guide wheel is arranged on a rotating shaft and is matched with the guide rail. One end of the connection rod is connected with the middle of the rotating shaft, and the other end of the connection rod is connected with the middle of a transverse support of a girder. A transverse adjustment lead screw of the adjustment supporting mechanism and the rotating shaft form a whole, and the transverse adjustment lead screw is connected with the girder through threads. A longitudinal adjustment lead screw is arranged between the middle of the transverse support of the girder and a rotating disc guide rail, and the longitudinal adjustment lead screw is connected with the transverse support of the girder and the rotating disc guide rail respectively through threads. A supporting wheel is arranged between the table facet and the rotating disc guide rail. The hydraulic folding minor repair working platform moved along with the derrick is delicate and compact in structural design, and is a working platform applicable to various well openings.

Description

technical field [0001] The invention relates to an oilfield workover auxiliary equipment, in particular to a hydraulic folding minor repair operation platform which is moved along with the derrick. Background technique [0002] At present, during minor repair operations in oilfields, the wellhead construction is generally carried out by two personnel, pushing and pulling, centering the tubing and sucker rod strings, helping and pulling the hydraulic tongs to make up and down the strings, and manually completing the lifting rings. Due to the complex work content and high labor intensity, the operations of picking, moving and hanging elevators, pulling and inserting elevator pins, etc., and the environment of the wellhead operation location is complicated, the pipelines are vertical and horizontal, and the ground is mixed with oil and water, which makes it muddy and slippery. There are many potential safety hazards, and safety accidents are prone to occur in operation and prod...
