Description

Ship pipeline welding centering device Technical Field The utility model provides a ship pipeline welding centering device, and belongs to the technical field of welding auxiliary equipment. Background In the field of modern ship construction and maintenance, equipment pipelines on ships are vital components, so that the installation quality of the ship pipelines is directly related to the normal operation and safety of the ships. For pipelines on ships, maintenance operations such as welding are often required to extend the pipeline under certain conditions and ensure the normal operation and use of the pipeline. It is often necessary to center the welded pipe to be welded with the fixed pipe prior to welding. For daily pipeline welding, after the welding pipe and the fixed pipe are centered, the stability of the welding pipe and the fixed pipe after centering can be ensured only by enabling the welding pipe and the fixed pipe to be relatively static with the ground. While the ship is running, the ship is easily subjected to continuous jolt and shake due to the influence of various complex factors. Because the welded pipe and the fixed pipe are in a separated and non-integrated state before welding, even if the welded pipe and the fixed pipe are centered, the pipeline to be welded can shift in position and change in angle along with the shaking of the ship, and the accurate centering of the pipeline is difficult to maintain by the traditional method. In view of the above, there is a need for a marine pipeline welding centering device. Disclosure of utility model The technical problem to be solved by the utility model is that the accuracy of pipeline centering is easily affected when the pipeline is welded due to poor stability of the ship, so that the pipeline welding quality is affected. The technical scheme is that the ship pipeline welding centering device comprises a clamping cylinder, a clamping plate, a pressing block and a centering column, wherein the clamping cylinder is arranged on the outer side of a fixed pipe, the clamping plate is arranged on the side face of the clamping cylinder in a sliding mode, the clamping plate is fixedly clamped on the fixed pipe connected to ship equipment, a clamping assembly capable of controlling the clamping plate to slide is arranged in the clamping cylinder, a welding pipe to be welded with the fixed pipe is sleeved on the centering column, the welding pipe is in butt joint with the fixed pipe, the centering column is inserted into the fixed pipe, the pressing block capable of enabling the welding pipe to be in butt joint with the fixed pipe to be pressed is fixedly connected with the clamping cylinder, and the pressing block is fixedly connected with the centering column. As an improvement, the pair of center posts corresponds to the inner diameters of the fixed pipe and the welded pipe. As an improvement, the clamping cylinder is fixedly connected with a connecting rod, and the connecting rod is fixedly connected with the compression block. The clamping assembly comprises a bidirectional screw rod and sliding blocks, wherein the bidirectional screw rod is rotatably arranged in a clamping cylinder, the two sliding blocks are in threaded connection with the corresponding positions of the bidirectional screw rod, guide grooves are formed in the clamping cylinder, guide rods fixedly connected with the sliding blocks are arranged in the guide grooves, and two clamping plates are fixedly connected with the guide rods. As an improvement, the clamping plate is an arc-shaped plate corresponding to the diameter of the fixed pipe, and an anti-slip pad is arranged on the inner wall of the clamping plate. The utility model has the beneficial effects that: The welding pipe is sleeved on the centering column, the centering column is inserted into the fixed pipe, and the centering column is arranged in the fixed pipe and the welding pipe simultaneously, so that the fixed pipe and the welding pipe can be centered accurately, and the butt joint tightness of the fixed pipe and the welding pipe is improved by using the compression block. Simultaneously, the grip block is fixed to be centre gripping on fixed pipe, and the welded pipe can keep integrative state through compact heap, grip cylinder, grip block and fixed pipe, and when boats and ships were rocked, fixed pipe can remain the relative static with the welded pipe all the time, can not influence the degree of accuracy of centering, and can not leave any connection trace on fixed pipe, welded pipe after the welding finishes.
