Embodiment Construction

[0035] Fig. 1, when in use, the pipe outer mating device is placed on the top of the pipe (21), in the middle of the two pipe welds, then the chain (19) connected to one end of the assembly box (5) is wound around the pipe, and the retractable end of the chain is used to Hook (22) is hung in the connecting ring (23) of short chain (7), moves operating handle (1) and makes dial claw (3) pushes gear (4) to rotate, and gear (4) stirs tooth bar motion and Shrink the chain, and the correction plate (20) on the chain forces the two pipes (21) to be pressed on the same axis, so as to achieve the purpose of aligning the pipe. If the nozzle has been deformed, use the correction bolt (18) on the correction plate (20) ) for correction, when moving the operating handle (1) to make the gear rotate, the brake pawl control gear does not reverse, the pipe matching ends, and when the pipe matching device is removed, moving the operating handle (1) backward is more than normal operation Pull so...

Abstract

The gear rack type plumbing quick matching device for plumbing welding joints, comprises gears, racks, sprockets, chains, steel wires and positioning rings, features in the teething major drive gear inside the bracket or gears in the fitting box or the wheel shifting claw on the wheel shift shaft inside the bracket, with the gear and rack or sprocket teething. In use, plumbing matching device is placed on the middle of the plumbing, circling one round of the chain connecting the matching machine, inserting the gear or sprocket at the end of the chains to the plumbing or matching device, pushing the operation bar driving the gear moving, gear shifting racks or sprockets, which shrinks the chains or steel wires. Rectifier plate forces the plumbing opening at the same axis, fastening plumbing matching device side shrinking positioning ring, realizing the matching of plumbing. It is simple, quick, energy saving with improved efficiency.

Description

technical field [0001] The invention relates to a rack-and-pinion quick mouthpiece for alignment of welding joints between pipelines in pipeline installation engineering. Background technique [0002] In the current pipeline installation project, the use of pipe counterparts has promoted the progress of the project, but there are still some shortcomings. For example, the fastening method of the pipeline outer chain counterparts uses screw or bolts, which takes a long time and is inefficient. The electrohydraulic device is huge, expensive, and inconvenient to move. Contents of the invention [0003] The purpose of the present invention is to provide a rack-and-pinion type pipe outer rapid counterpart that is simple to operate, rapid and accurate. In order to achieve the above object, the rack-and-pinion type pipe outer quick counterpart of the present invention is composed of gears, racks or toothed chains and chains or steel wire ropes and correction systems; [0004] De...
