Description

Pipeline welding positioning tool for ship building Technical Field The invention relates to the field of ship pipeline welding, in particular to a pipeline welding positioning tool for ship repair and construction. Background In the ship building industry, pipeline welding is an important core process, and the quality of welding directly influences the integrity of the whole structure of a ship, the running performance of a power system and the safety of long-term sailing. In a practical shipboard operating environment, various types of pipelines are generally designed centrally and fixedly installed on top of cabins due to the special layout of the internal space of the ship. This general mounting means leads to operating personnel to need to carry single length several meters, the considerable pipeline of weight to the operation position of several meters height through simple and easy hoisting equipment or manpower first to under the high altitude state, rely on artifical support or temporary support to carry out rough location, and the poor defect such as direct welding stress concentration, root incomplete penetration, inner wall shaping that leads to in the centering seriously weakens welding seam intensity, buries down leakage even the hidden danger of fracture for pipe-line system long-term operation. Therefore, a pipeline welding positioning tool for ship building is provided. Disclosure of Invention The invention aims to provide a pipeline welding positioning tool for ship building, which is used for solving the problem that manual support or temporary support is relied on for rough positioning in a high-altitude state. The process not only consumes a great deal of physical strength, but also is difficult to control when the pipeline shakes at a high place, and the problems of accuracy and stability in centering required by welding are difficult to realize. In order to achieve the above purpose, the present invention provides the following technical solutions: The utility model provides a pipeline welding position frock for boats and ships are repaired, includes the frock body, install the fixation clamp on the frock body, fixed mounting has the stock on the frock body, be hollow structure in the stock, fixed mounting has a plurality of pulleys in the stock, place the hawser on the pulley, this internal fixed mounting of frock has driving motor, be connected with the capstan winch on the driving motor output shaft, the one end and the capstan winch fixed mounting of hawser, the other end fixed mounting of hawser has the rack, the equal fixed mounting in both sides of frock body has the sliding column, set up the through-hole on the frock body, the through-hole is internal to be connected with the double-end threaded rod, sliding connection has the fixed plate on the sliding column, double-end threaded rod and fixed plate threaded connection, sliding connection has centering grip block on the fixed plate, two form loudspeaker column structure between the centering grip block, this internal promotion subassembly of installing of frock, the promotion subassembly is connected with centering grip block, after the rack removes appointed position, the promotion subassembly promotes centering grip block and removes. In practical shipboard operating environments, due to the special nature of the internal space layout of the hull, various types of piping are typically designed to be installed in the top area of the channel to avoid interference with personnel traffic and equipment operations. This mounting means results in that, when welding the pipes, the operator must first carry the pipes to be welded to a high free position and then perform the precise centring and welding operation. In order to solve the problems, the operation flow of the tool is as follows, the fixture body is firstly installed on a finished pipeline on one side by using the fixing clamp, the driving motor is started, the driving motor drives the winch to rotate, the winch pulls the placing frame and the pipeline to be welded on the placing frame to move through the cable, the pipeline to be welded is stably pulled to a preset position, and after the pipeline reaches a target position, the pushing assembly is operated to drive the centering clamping plate to accurately center and reliably clamp the pipeline. Through the structure, accurate positioning and stable fixation in the pipeline hoisting process are effectively realized, and the operation efficiency and safety are remarkably improved while the welding precision is improved. Preferably, the pushing assembly comprises a hydraulic rod, the hydraulic rod is fixedly installed on a fixed plate, the pushing plate is installed at the movable end of the hydraulic rod, connecting plates are connected to two sides of the pushing plate in a sliding mode, the connecting plates at two ends are fixedly installed on the centering clamping plates at two sides respectively, a plurality of sli
