Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing, in particular to a pipeline welding tool. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for transporting gas, liquid or fluid with solid particles. Pipes are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects and various industrial devices.

[0003] Since the pipeline has a curved section and a straight section, the two are welded together. It is relatively simple to weld between straight sections; however, the welding between the curved section and the straight section cannot be directly clamped and fixed for welding because both ends are elbows. In the existing operation, most of the pipelines are directly fixed and welded manually, which has low welding efficiency and uneven welding quality.

[0004] Therefore, patent CN218556136U, "A pipeline auxiliary welding tool" proposes a technical solution to the above problems. In this patent, the bending section and the straight section of the pipeline are transferred by the tool, and the chuck of the positioner is used to drive the straight section of the pipeline to rotate around its center, and the positioner is used to automatically weld. However, this tool is only suitable for welding between single angles. In actual use, the bending direction and angle of the pipeline are different. When the overall structure of the pipeline is more complicated, interference will occur when the tool disclosed in the above patent is used to assemble the pipeline; and this tool can only assemble and weld two adjacent pipelines, and then continue to assemble and weld the next adjacent pipeline. Such operation greatly reduces the assembly and welding efficiency, and there are safety hazards to a certain extent.

[0005] Therefore, designing a pipeline welding tool is an important technical problem that technicians in this field need to solve. Utility Model Content

[0026] The purpose, advantages and features of the present invention will be illustrated and explained through the non-limiting description of the following preferred embodiments. These embodiments are only typical examples of the application of the technical solution of the present invention, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection claimed by the present invention.

[0027] In the description of the scheme, it should be noted that the terms "center", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0028] As Figures 1 to 4 As shown, the utility model discloses a pipeline welding tool, which is arranged below a welding head. Specifically, it comprises a support seat 1 and a pipeline bearing plate 2 pivotally arranged on the support seat 1. The support seat 1 comprises a support base and a vertical portion 11 arranged perpendicularly to each other, and the pipeline bearing plate 2 is arranged on the vertical portion 11.

[0029] like Figure 1 As shown, the side of the pipeline support plate 2 is the pipeline end start-end surface 20, that is, the inlet section and the outlet section of the pipeline are both located at the pipeline end start-end surface 20. In order to further improve the accuracy of the pipeline connection, the present application preferably provides an abutment plate on the end surface of the inlet section and / or outlet section of the pipeline, and the end surface of the inlet section and / or outlet section of the pipeline abuts against the abutment plate when the pipeline is placed.

[0030] The upper surface of the pipeline bearing plate 2 is provided with a pipeline positioning device 21 and a pipeline clamping device 22; the layout of the pipeline positioning device 21 is consistent with the pipeline routing layout, which can meet the assembly and welding requirements of various pipeline shapes and has a wide range of applications. The positioning device 21 and the pipeline clamping device 22 are both arranged on the straight section of the pipeline. The placement position of the pipeline on the pipeline bearing plate 2 can be limited by the pipeline positioning device 21 and the pipeline clamping device 22, and the subsequent welding operation is convenient after the position is limited, while ensuring the stability of the pipeline during the welding process.

[0031] Furthermore, the top end of the vertical portion 11 is formed with an opening for pivotally connecting a positioning rod 102, and the distal end of the positioning rod 102 is fixedly connected to the center of the pipe support plate 2, and drives the pipe support plate 2 to rotate around the pivot point of the positioning rod 102, so that the pipe support plate 2 switches back and forth between the first state and the second state. Specifically, the first state is the state of loading and unloading the pipe, at which time, the pipe support plate 2 is parallel to the vertical portion 11 of the support seat 1 and the setting direction of the welding head. The second state is the state of the pipe to be welded, at which time, the pipe support plate 2 is perpendicular to the vertical portion 11 of the support seat 1 and the setting direction of the welding head, and is located directly below the welding head.

[0032] In order to prevent the pipe support plate 2 from excessively rotating, a support block 12 is preferably provided on the side of the vertical portion 11 opposite to the pipe support plate 2 in the present application. The distance between the support block 12 and the pivot point of the positioning rod 102 is not greater than the distance between the pivot point of the positioning rod 102 and the pipe support plate 2 in the first state, thereby ensuring that the lower surface of the pipe support plate 2 in the second state abuts against the top of the support block 12. The support block 12 applies a supporting force to the lower surface of the pipe support plate 2 in the second state, thereby ensuring the stability of the pipe support plate 2 and the pipe placed thereon during welding, thereby ensuring the welding quality.

[0033] like Figure 2 As shown, at least one welding port 200 is provided on the pipe bearing plate 2, and the connection ports of two adjacent pipes are located at the welding port 200. The number of the welding heads is consistent with the number of the welding ports 200. Providing welding ports on the pipe bearing plate 2 can reduce its overall mass, and at the same time reduce the bearing capacity of the support seat 1, thereby playing a lightweight role; at the same time, the welding ports can facilitate the welding head to weld and fix the connection ports at the connection of the two pipes, which is convenient for operation. When there are more than two connection ports, the welding heads located above the welding ports can work synchronously to improve welding efficiency.

[0034] Furthermore, when the pipe supporting plate 2 rotates to the second state, a waste collection frame (not shown in the figure) is provided directly below the welding port 200 to collect waste generated during welding, effectively preventing waste from splashing and affecting the welding environment. The waste collection frame can be removed after the welding operation is completed, and the waste can be uniformly processed, effectively reducing the risk of environmental pollution.

[0035] like Figure 1 to Figure 2As shown, the pipeline positioning device 21 includes at least a set of first positioning blocks 211 and second positioning blocks 212. The first positioning block 211 is composed of two fixed blocks arranged in parallel on the pipeline support plate 2, and the gap between the two fixed blocks is equivalent to the diameter of the pipeline. The second positioning block 212 is arranged on the pipeline support plate 2 in a groove shape. The bottom of the groove of the second positioning block 212 is higher than the bottom of the groove of the first positioning block 211, and a height difference is formed between the two, so that the pipeline can transition smoothly.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, the pipe clamping device 22 at least includes an end clamp 221. The end clamp 221 includes a driving part, a telescopic part driven by the driving part, and an abutment part fixedly connected to the telescopic part; the driving part is rotated to drive the abutment part to approach or move away from the pipe end start-stop surface 20 to clamp or loosen the inlet section and outlet section of the pipe. It can be seen that the inlet section and outlet section of the pipe are positioned by the end clamp 221, and the main part of the pipe is positioned by the pipe positioning device 21, which can effectively ensure the stability of the pipe placement position.

[0037] Furthermore, the pipe clamping device 22 also includes an upper clamping member 222 and an anti-shake clamping member 223 disposed on the upper surface of the pipe bearing plate 2. The upper clamping member 222 includes a clamping portion and a clip portion fixedly connected to the clamping portion. The clamping portion of the upper clamping member 222 is detachably disposed on the pipe bearing plate 2; the clip portion is Z-shaped and is located at the welding port 200. The clip portion is driven by the clamping portion to approach or move away from the upper surface of the pipe at the welding port 200. The anti-shake clamping member 223 is a clamping structure, which is detachably disposed on the pipe bearing plate 2 through a connecting block. The anti-shake clamping member 223 is disposed on the outer side of the welding port 200, and applies a force to the upper surface of the pipe between two adjacent first positioning blocks 211, or the upper surface of the pipe on the first positioning block 211, or the upper surface of the pipe on the second positioning block 212. Since the clamping structure is a known prior art, it will not be described in detail here.

[0038] In the present application, the end clamp 221, the upper clamp 222 and the anti-shake clamp 223 are used to apply force to the inlet section, the outlet section and the main part of the pipe, so that the pipe is as close to the surface of the pipe supporting plate 2 as possible. At the same time, the first positioning block 211 and the second positioning block 212 are used to limit the position of the pipe in the width direction, thereby ensuring the stability of the pipe placement, reducing the shaking amplitude during welding, and effectively improving the welding efficiency, quality and yield rate.

[0039] There are many implementation methods of the utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
