Adjustable flexible track device for pipeline

Abstract

The invention discloses an adjustable flexible track device for a pipeline, which is characterized by comprising a flexible track, a hasp component and a plurality of double-folded combined springs, two free ends of the flexible track are butted through the hasp component, the plurality of double-folded combined springs are mounted on an inner ring of the flexible track, and the double-folded combined springs are adjustably clamped on the pipeline. The device can automatically adapt to the deformation of the pipeline and a small amount of size errors, operators do not need to guess a covering belt on site to consider that the tightness degree is appropriate, the number of needed operators is small, the number of operation actions is small, and the device is more user-friendly. Due to the fact that the pull rod with the fixed length and the hasp assembly with the two-way positioning function are adopted, accurate closing of the track is guaranteed, and operators can conveniently assemble and disassemble the track on site.

Description

technical field [0001] The invention relates to an adjustable flexible track device for pipelines. Background technique [0002] The most common method for butt jointing of two pipes is to weld the two pipes mouth to mouth, and the butt weld is a circular weld. During welding, the welding torch and welding wire must continuously walk a full circle around the circumference of the pipeline along the circular weld to meet the welding movement requirements of the butt circular weld. In order to ensure that the welding torch is continuous and stable when walking in a circle, a set of circular track tooling is generally installed on the pipeline, and a trolley that can move along the track is installed on the track, and then welding torches and other equipment are installed on the trolley. During welding, the driving trolley runs along the track, so that the track of the welding torch welding wire matches the annular butt joint of the pipeline. [0003] After the welding is comp...

Problems solved by technology

But in the application of actual product, there is such problem: 1) spring is not adjustable

2) The operation of the track closing connection is cumbersome, requiring multiple operators and multiple operating procedures, for example, manually bringing the connecting blocks at both ends of the track as close as possible, and then threading and screwing the screw

The most important thing is that after the installation is completed, there is no guarantee that the tightness of the track installed this time is suitable for this pipe. If the tightness is not suitable, it is necessary to properly adjust the gasket between the spring and the track bar to obtain a suitable tightness
