Description

Technical Field

[0001] The present application relates to the technical field of pipe welding, and in particular to a tool for assisting pipe fixing and welding. Background Art

[0002] A pipeline refers to a system composed of multiple pipes and pipe fittings such as valves, elbows, tees, flanges, and joints. In order to cooperate with the production process, the pipeline needs to be reasonably laid out and arranged to avoid conflicts with buildings and other production equipment.

[0003] In the prior art, the corners of pipelines are usually connected by elbows at the joints of two pipes. However, the needs on site vary, and there are different requirements for the angles of the corners of the two pipes. Elbows are usually standard parts and cannot meet the connection requirements of all non-standard angles of pipe parts. Therefore, the connection corners of different angles between two pipes are usually achieved by welding.

[0004] In the process of pipe welding, the accuracy and stability of pipe butt joint have a decisive influence on the welding quality. At present, pipe welding mainly relies on manual butt joint, which not only has poor stability, but also makes it difficult to achieve accurate angle fit. Utility Model Content

[0005] In order to improve the accuracy of pipe welding angles, the present application provides an auxiliary pipe fixing welding tool.

[0006] The auxiliary pipe fixing welding tool provided in this application adopts the following technical solution:

[0007] An auxiliary pipe fixing welding tool comprises a support sleeve, a fixed support fixedly arranged on the support sleeve, and an adjustable support rotatably arranged on the support sleeve along the circumference of the support sleeve, wherein the length directions of the fixed support and the adjustable support are both arranged perpendicular to the axial direction of the support sleeve, and a fastener is arranged on the adjustable support. The fastener is used to adjust the support angle to achieve the fixation between the adjustable support and the support sleeve, and both the fixed support and the adjustable support are provided with a fastening piece for fastening the pipe.

[0008] By adopting the above technical solution, when in use, first fix a pipe on the fixed support through a fastener; then rotate the adjustment support according to the welding angle until the angle between the adjustment support and the fixed support with the support sleeve as the hinge point is adjusted appropriately, and then use the fastener to fix the position of the adjustment support and the support sleeve at this time; place another pipe on the adjustment support, and make one end of this pipe fit tightly with the opposite end of the pipe fixed on the fixed support, and then fix this pipe on the adjustment support through the fastener. At this time, the welding ends of the two pipes to be welded are accurately butted and fit tightly, and the welding operation can be carried out.

[0010] By adopting the above technical solution, when it is necessary to fix the adjustment support, it is only necessary to tighten the fixing nut so that the side wall of the support sleeve is pressed between the connecting plate and the fixing nut, thereby achieving the fixation of the adjustment support; conversely, loosen the fixing nut, and a movable gap is left between the adjustment support and the support sleeve. At this time, the angle between the adjustment support sleeve and the fixed support can be slid along the guide of the through hole.

[0011] Optionally, the support sleeve is provided with angle scales along the length of the through hole.

[0013] Optionally, an anti-slip pad is provided on the side wall of the adjustment support that contacts the support sleeve.

[0014] By adopting the above technical solution, when it is necessary to fix the adjustment support, tighten the nut so that the side wall of the support sleeve is pressed between the connecting plate and the nut. At this time, the anti-slip pad is in contact with the outer wall of the support sleeve, which can enhance the stability of the fixation between the adjustment support and the support sleeve.

[0015] Optionally, two rubber washers are sleeved on the bolt, and the supporting sleeve is located between the two rubber washers.

[0016] By adopting the above technical solution, two rubber washers are respectively located on the inner and outer sides of the support sleeve and are sleeved on the bolt. When tightening the nut to fix the support sleeve and adjust the position relationship of the sleeve, the side wall of the support sleeve can be protected, reducing the possibility of scratches or indentations on the side wall of the support sleeve caused by tightening the nut, thereby extending the service life of the fixed welding tool.

[0022] By adopting the above technical solution, the setting of the support arc seat reduces the possibility of the pipe rolling off the fixed support during the tightening process, and improves the stability of the fixed pipe. At the same time, the setting of the rubber gasket enhances the stability of the pipe when tightening, and reduces the possibility of the pipe rotating during the tightening process.

[0023] Optionally, a rubber sleeve is provided at the end of the tightening screw facing the supporting arc seat through a threaded sleeve.

[0024] By adopting the above technical solution, a rubber sleeve is sleeved on the end of the tightening screw to further protect the pipe and reduce the possibility of damage to the pipe due to excessive tightening force.
