Problems solved by technology
[0003] In the process of laying and welding oil and gas pipelines, since the oil pipelines are long and heavy, large-scale lifting equipment will be used for lifting and handling. At the same time, more lifting equipment is required for construction and laying, which increases the construction cost. Wrapping and fastening the middle part of the pipe with a sling is easy to cause deformation of the pipe. It is inconvenient to install and remove the sling. At the same time, when the two pipes are welded, lifting equipment is required to lift the welding ports of the two pipes, and the ports are easy to shake. But the problem of not being able to better align and stick together, thus affecting the welding effect

The invention discloses a device used for laying and jointing of oil and gas field development pipelines. The device comprises arc-shaped clamping blocks, an arc-shaped block, hydraulic push rods, bottom plates, a hanging beam plate, T-shaped slide blocks, cube plates, positioning bolts, U-shaped plates, electric-hydraulic push rods, a motor, a circular plate, a control cabinet, an omega-shaped plate, right-angled supporting plates, rollers, T-shaped slide grooves, a square through hole, a T-shaped circular block, a cube press rod, a threaded through hole and a threaded rod. The device provided by the invention is reasonable in design and has a pipeline clamping structural function, the traditional mode that the pipelines are wrapped with slings and then hoisted is changed, the various pipelines with the different pipe diameters can be clamped conveniently, the structure is compact, the number of used large hoisting equipment is decreased, in addition, the construction cost is saved, the device is applicable to carrying of the pipelines in a stacking place on the ground, operation is convenient and fast, two jointing ends can be attached in a matched mode easily, and it is guaranteed that the jointing operation is performed smoothly.
Description
technical field [0001] The invention relates to a device for laying and welding pipelines, in particular to a device for laying and welding pipelines for oil and gas field development, and belongs to the technical field of oil and gas field development and application. Background technique [0002] Oil and gas fields refer to the sum of oil reservoirs, gas reservoirs, and oil and gas reservoirs in the same area controlled by a single local structural unit. If there are only oil reservoirs in this local structural range, it is called an oil field, and only gas reservoirs are called a gas field. [0003] In the process of laying and welding oil and gas pipelines, since the oil pipelines are long and heavy, large-scale lifting equipment will be used for lifting and handling. At the same time, more lifting equipment is required for construction and laying, which increases the construction cost. Wrapping and fastening the middle part of the pipe with a sling is easy to cause defo...
