Embodiment Construction
[0032] The present invention will be further described below in conjunction with accompanying drawing:
[0033] Such as Figure 1 to Figure 15 As shown, it includes the body, and the electric control and hydraulic systems that provide power and control commands for the body. The arm pipe feeding mechanism is composed of 5;
[0034] Wherein, the upper and lower pipe mechanism 1 is composed of a welded stabilizer vertical plate 6, a leg hydraulic cylinder 7, an upper pipe shift fork 8, an upper pipe shift fork hydraulic cylinder 9, a lower pipe shift fork 10, and a lower pipe shift fork hydraulic cylinder 11. It is formed with the upper and lower pipe mechanism support base 12; one end of the upper pipe shift fork 8 and the lower pipe shift fork 10 is designed to be an arc-shaped structure consistent with the shape of the oil pipe, and the other end is hinged with the upper part of the welded stabilizer vertical plate 6 The piston rod of the upper pipe shift fork hydraulic cyl...

An automatic column moving device for workover mainly solves the problems in existing workover operations of high labor intensity and high risk due to manual arrangement of tubes. The automatic column moving device is characterized in that a main body is composed of an upper and lower tube mechanism, a fixed base, a deflecting and lifting slideway and an outstretched arm tube feeding mechanism; the upper and lower tube mechanism pushes an upper and lower tube fork to finish the up and down of tubes through a hydraulic cylinder; the deflecting and lifting slideway pushes the slideway to finish the deflecting and lifting work though the hydraulic cylinder connected with the base; the outstretched arm relays on a guide wheel to roll on the slideway, and a hydraulic piston rod of the outstretched arm is used for completing the telescopic actions; and the outstretched arm device drives a sprocket wheel through a motor so as to drive a tubing of a chain. The chain is used for driving the tubing in the automatic column moving device, thereby realizing the transfer operation of the columns between an operating platform and a lay-down rack. Furthermore, the automatic column moving device is capable of quickly and accurately realizing the up and down operations of the tubings, so that the workover cycle is shortened, and workover workers' labor intensity and the number of the workover workers are reduced.
Description
technical field [0001] The invention relates to a mechanized transporting device for pipe strings in well repairing operations in oil and gas fields. Background technique [0002] During the workover operation, it is necessary to perform a large number of tripping and discharging operations on the sucker rod, casing and tubing, especially during the tripping process, it is necessary to repeat the pipe string discharge operation many times. In the process of pipe string discharge, it is required that the pulled out pipe strings can be neatly arranged and released in the required order when the pipe is lowered. In the prior art, the discharge operation of the pipe string is completed manually by using mechanical tools, which not only takes a lot of time, but also has high labor intensity and high safety risks. Contents of the invention [0003] In order to solve the existing technical problems given in the background technology, the patent of the present invention proposes...
