Description

Technical Field

[0001] The present application relates to the technical field of water conservancy engineering, and more specifically, to a positioning device for water conservancy pipeline welding. Background Art

[0002] Water conservancy pipeline engineering is a pipe (channel) system engineering that transports and distributes industrial water supply and domestic drinking water, and collects, transports and discharges industrial wastewater, domestic sewage and rainwater. When water conservancy projects use and divert water resources, they often need to lay pipelines, which are then butt-jointed through positioning devices and welded.

[0003] Chinese patent number CN216715395U discloses an auxiliary pipe lowering device for water conservancy projects, including a base frame and a positioning device, the base frame is U-shaped, the positioning device is installed inside the base frame, the positioning device includes a slide rail and a bolt, and the base frame is fixedly connected with two slide rails. According to the utility model, when using the positioning device, first clamp the two half sliders on the slide rail, dock the teeth, weld and fix them, then weld the positioning blocks on the two half sliders, and then weld the arc blocks on the positioning blocks, and then fix the push rod and the connecting plate with bolts so that the two positioning blocks are in a straight line, put the pipeline on the extrusion block, hold the handle, move the pipeline, connect the pipeline with the inner surface of the base frame, and then use the fastening device to limit and fix it. This positioning device can be adjusted according to the size of the pipeline, has strong universality, and is convenient for fine-tuning the position and docking. This fastening device is easy to install and prevents the pipeline from shaking and moving.

[0004] Although the device has many beneficial effects, it still has some shortcomings that need to be improved. The water conservancy pipeline is large in size, the pipeline movement is inconvenient, and the docking position of the two pipelines needs to be manually identified. It is impossible to confirm whether they are in the same straight line, which can easily cause deviations in the pipeline welding, waste welding materials and poor pipeline welding effect. In view of this, we propose a positioning device for water conservancy pipeline welding. Utility Model Content
