Embodiment Construction
[0023] Such as figure 1 and figure 2 As shown, the oil pipe placement device of the present invention includes two guide rails 1 and a sliding car 2 placed on the two guide rails 1 . The trolley 2 includes a frame 34 . The left and right ends of the vehicle frame 34 respectively pass through a third connecting shaft 35 . The front and rear ends of each third connecting shaft 35 are respectively equipped with rollers 39 , and each roller 39 is respectively placed on the two guide rails 1 . Two guide rails 1 are located on two supports 3 . The longitudinal sections of the two brackets 3 are both U-shaped. The outer surfaces of the two brackets 3 are respectively connected with a support plate 40 and a second connecting shaft 36 , and the left and right ends of the two guide rails 1 are respectively welded and fixed on the upper surfaces of the two support plates 40 . Each support plate 40 is respectively located above each second connecting shaft 36 . Two brackets 3 are p...

The invention provides an oil tube arrangement device, and belongs to devices for conveying tubes outside wells. The oil tube arrangement device comprises two lead rails which are fixed on two supports, wherein the two supports are placed on two chassis; two pieces of first vertical channel steel are arranged on the upper surfaces of the chassis; two pieces of second vertical channel steel are connected with the back of each support, and arranged in the two pieces of first channel steel by means of slipping; a first hydraulic oil cylinder is connected between each chassis and corresponding support; lower traction devices are respectively connected on the two supports; and each traction device comprises a toothed clutch; one toothed clutch is connected with a main shaft which passes through a front plate of the support to be connected with a motor, and another toothed clutch is connected with a driven shaft which passes through a rear plate of the support; a roller externally coiled with ropes is arranged on the external surface of the driven shaft; ropes of two power traction devices are connected with a sliding trolley; and an oil tube clamping device is arranged on the upper surface of the sliding trolley. With the adoption of the oil tube arrangement device, the service life of a thread at the end of an oil tube is prolonged, a worker is safe and convenient to load and unload the oil tube, and the workload of the worker is reduced.
Description
technical field [0001] The invention relates to a device for transporting pipes outside the borehole, in particular to a device for placing oil pipes. Background technique [0002] At present, in oil field workover operations, the vertical oil pipe lifted from the oil well is placed on the sliding car, and then the oil pipe moves with the sliding car, and the process of gradually lowering the upper end of the oil pipe is as follows: the worker places the lower end of the lifted vertical oil pipe on two sides. On the sliding car on a guide rail, the upper end of the oil pipe is connected to the lifting device, and it will descend as the lifting device descends. And the hoisting equipment lowers the upper end of the oil pipe to the wellhead area at most. The wellhead area is about three meters high from the area where the oil pipe is placed. The lower end of the oil pipe is placed on the upper surface of the sliding car. Under the gravity of the oil pipe, the sliding car slid...
