Embodiment Construction

[0054] The specific implementation manner of the present invention will be briefly described below in conjunction with the accompanying drawings.

[0055] Such as figure 1 As shown, a multi-station clamping device for gas pipeline laser shock test, the movement structure mainly has three parts: gas pipeline clamping and rotary drive part; pipeline support length adjustable, variable diameter pipeline support part; pipeline axial Feed drive section.

[0056] Such as figure 2 , image 3 As shown, the fixed bracket positions the clamping mechanism.

[0057] The main components of the mechanism: end cover 2, cylindrical roller 3, outer ring support 4, clamping bolt 5, inner ring 6 and screw 1. Among them, the selection of cylindrical roller 3 can ensure the stability of the gas pipeline rotation; the base of the outer ring bracket 4 is fixed on the movable base plate 28 to realize the feed movement along the pipeline axis; three clamping bolts 5 are distributed in the inner r...

Abstract

The invention aims to provide a multi-station clamping device for fuel gas pipeline laser shock test. The device includes a bottom plate and a movement structure. The movement structure mainly includes: a fuel gas pipeline clamping and rotary driving part, called clamping part for short; a pipeline support length adjustable and variable diameter pipeline supportable part, called adjustment part for short; and a pipeline axial feed driving part, called driving part for short. The bottom plate includes a fixed bottom plate structure, a movable bottom plate structure and a test base station. Directed at fuel gas pipeline laser shock test, the invention designs the device meeting clamping and movement requirements, avoids personal injury, reduces manpower, improves labor productivity and reduces production costs, and is also the necessary condition for realizing production automation.

Description

technical field [0001] The invention relates to a gas pipeline clamping device, in particular to a multi-station clamping device for a gas pipeline laser impact test. Background technique [0002] Pipeline is a key part of energy transmission equipment such as natural gas and gas. It is an important part of urban pipeline network and natural gas west-east transmission project. The pipeline system for long-distance transmission is welded by multiple steel pipes and elbows. There are many places and large The welding area of ​​the area, the quality of the weld directly affects the performance of the pipe network. The laser shock treatment technology is used to treat the weld surface, which is very beneficial to the mechanical properties of the pipeline weld, can increase the tolerance to internal impact and external strong damage, shorten the maintenance time of the gas pipeline, and reduce the occurrence of accidents in the process of energy transmission Rate. [0003] The ...
