Embodiment Construction

[0040] The present invention will be further described below in conjunction with accompanying drawing:

[0041] Depend on Figure 1 to Figure 20 As shown, the present invention develops an inner liner device used in pipeline welding construction, which is suitable for small and medium-diameter pipelines. The liner is easy to disassemble and can be easily adjusted with changes in the diameter of the pipeline.

[0042] The technical solution adopted by the present invention to solve the technical problem is: the device consists of a head supporting counterpart, a head pad guiding part, an intermediate cylinder rod connecting part, and a tail push-pull positioning part.

[0043] There are 6 groups of said head support counterparts, each group includes 1 fixed top wire, 1 wear-resistant steel ball, several spacer spacers, 1 steel ball cylinder, and 1 steel ball seat. On the left and right sides of the arc-shaped liner of the device, there are 3 sets of head support counterparts, ...

Abstract

The invention relates to a pipe welding arc-shaped liner device. According to the aim, a liner device which can be used for improving the welding quality during pipe construction is provided. The pipewelding arc-shaped liner device is characterized by comprising six sets of head support opening alignment components, a head liner guide and push component, a middle barrel rod connecting component and a tail push and pull positioning component; each set of head support opening alignment components comprises a fixed jackscrew, a wearable steel ball, a plurality of distance adjusting gasket, a steel ball barrel and a steel ball base; the head liner guide and push component comprises a support barrel, a sliding ring, a compression spring, a fixing ring, a guide rail rod, a sliding support, an arc-shaped liner, a limiting bolt and a nut; the middle barrel rod connecting component comprises a connecting barrel, a barrel coupling, a connecting rod and a rod coupling, and the middle barrel rodconnecting component is used for connecting the head and the tail of the device and transmitting rotation or push-and-pull motion of the tail; and the tail push and pull positioning component comprises a push-and-pull handle and a clamping reed.

Description

technical field [0001] The invention relates to a welding backing device, in particular to an arc-shaped backing device used in pipeline construction for improving welding quality. Background technique [0002] During pipeline construction, except for super-large-diameter pipelines that can enter people, due to the limitation of conventional pipeline diameters, personnel cannot enter the pipeline for welding, and can only perform single-sided welding on the outside, which may easily cause unwelded welds on the inner wall of the pipeline. Defects such as penetration and weld bumps affect the quality of welds. [0003] The welding backing technology is to attach a ceramic or copper backing to the back of the weld to seal the welding groove when performing single-sided welding, thereby constraining the shape of the welding pool, forming a good weld quality, and avoiding welding seams. Defects such as incomplete penetration and weld bumps appear. Welding liner technology needs...
