Technical Field

[0001] The utility model mainly relates to the technical field of pipeline welding support equipment, in particular to a welding device for pipeline installation. Background Art

[0002] When installing pipelines, brackets are usually required to improve the strength of the pipeline installation and avoid safety hazards caused by unstable pipeline installation.

[0003] However, the size of the welding brackets for pipe installation currently on the market is fixed during use and cannot be adjusted according to the diameter of the pipe. When the pipe diameter changes, the clamping device is difficult to fit the outer wall of the pipe, which will make it difficult to firmly clamp and fix the pipe after the welding bracket is installed. In addition, during the welding installation process, some pipes need to be rotated to weld at different positions of the pipe. The bracket in the prior art needs to loosen the pipe and then adjust the position of the pipe, and also needs to re-fix the pipe, which is complicated to operate and affects the work efficiency of the user.

[0023] Embodiment: A welding device for pipe installation

[0024] like Figure 1-6 As shown, a welding device for pipeline installation, its specific structure includes:

[0025] A base 1, wherein two lower clamping plates 2 are fixedly installed on the top surface of the base 1 and are symmetrically arranged front and back, and upper clamping plates 4 matching with them are respectively arranged above the lower clamping plates 2, and clamping components are respectively arranged on the opposite sides of the lower clamping plates 2 and the upper clamping plates 4, and the two upper clamping plates 4 are fixedly connected to the base 1 through a lifting component.

[0026] The clamping assembly includes a semicircular movable plate 5, and the upper clamping plate 4 and the lower clamping plate 2 have a plurality of arc-shaped grooves 6 on opposite sides thereof, and the movable plates 5 are slidably installed in the arc-shaped grooves 6. The movable plate 5 has a plurality of wheel grooves 7 on one side outside the arc-shaped grooves 6, and rollers 8 are rotatably installed in the wheel grooves 7. When this structural design is in use, the upper clamping plate 4 and the lower clamping plate 2 cooperate with each other to achieve clamping and fixing of the pipeline. In the process of clamping the pipeline, the upper clamping plate 4 moves closer to the lower clamping plate 2, and the movable plate 5 located at the top of the lower clamping plate 2 contacts the bottom of the pipeline, and the movable plate 5 located at the bottom of the upper clamping plate 4 contacts the top of the pipeline. When the movable plate 5 clamps the pipeline, the rollers 8 on the movable plate 5 contact the outside of the pipeline respectively. The movable plate 5 can automatically adjust its own inclination according to the pipelines of different diameters, so that the movable plate 5 can apply an inclined force to the pipeline. The force directions of the two diagonally distributed movable plates 5 are opposite, thereby improving the clamping effect of the device on the pipeline. The rollers 8 can facilitate the user to rotate the pipeline during the pipeline welding process, thereby improving the flexibility of the device.

[0027] A slider 9 is fixedly installed in the arc groove 6, and the arc surface of the movable plate 5 is respectively provided with a slide groove 10 that slides with the slider 9. The mutual cooperation between the slider 9 and the slide groove 10 can realize the limit of the movable plate 5, and improve the stability of the movable plate 5 during the rotation process.

[0028] The two ends of the slide groove 10 are closed structures. This structural design can prevent the movable plate 5 from rotating too much and causing it to disengage from the arc groove 6, thereby improving the reliability of the device.

[0029] The lifting assembly includes a screw sleeve 11, and the two upper clamping plates 4 are fixedly connected by a U-shaped bracket 12. The two ends of the U-shaped bracket 12 are respectively fixedly connected to one side of the corresponding upper clamping plate 4. The screw sleeve 11 is fixedly installed on one side of the U-shaped bracket 12. A screw rod 13 that vertically penetrates the screw sleeve 11 and is threadedly connected to the screw sleeve 11 is rotatably installed on one side of the top surface of the base 1, and a crank 14 is fixedly installed on the upper end of the screw rod 13. When this structural design is used, the user can drive the screw rod 13 to rotate by turning the crank 14, so that the screw sleeve 11 drives the upper clamping plate 4 to move downward through the U-shaped bracket 12, thereby adjusting the position of the upper clamping plate 4 to achieve the clamping of the pipeline.

[0030] A plurality of limiting rods 15 are fixedly installed on one side of the top surface of the base 1, and a sliding sleeve 16 is slidably installed on the outside of the limiting rod 15, and the sliding sleeve 16 is fixedly connected to one side of the U-shaped bracket 12. When this structural design is used, the U-shaped bracket 12 can be limited by the mutual cooperation between the sliding sleeve 14 and the limiting rod 15, thereby ensuring that the screw sleeve 11 will not rotate during the rotation of the screw rod 13, thereby improving the stability of the U-shaped bracket 12 when moving.

[0031] Universal wheels 3 are fixedly mounted at the four corners of the bottom surface of the base 1, and the universal wheels 3 are self-locking universal wheels. The universal wheels 3 can facilitate users to move the position of the base 1, and can assist workers in transferring pipelines during use, further improving the use effect of the device.

[0032] Directions:

[0033] When the device is in use, the universal wheel 3 at the bottom of the base 1 can be used to easily push the device to the vicinity of the pipe to be welded. After reaching the designated position, the pipe to be welded is placed above the lower clamping plate 2, ensuring that the axis of the pipe is aligned with the center of the device. By rotating the crank 14, the screw 13 is driven to rotate, and the screw sleeve 11 moves up and down accordingly, driving the U-shaped bracket 12 and the upper clamping plate 4 to rise and fall synchronously until the upper clamping plate 4 fits tightly against the top of the pipe, thereby achieving a firm clamping of the pipe. Since the device has firmly clamped the pipe, the worker can start to use the welding gun for welding. The roller 8 on the movable plate 5 is designed to allow the pipe to be slightly rotated during the welding process, which is convenient for welding from all angles and improves the work efficiency and welding quality.

[0034] In the interpretation of the present invention, it should be noted that the terminology indicating the orientation is only for the convenience of description and understanding, and is not the only limitation on the installation position of the specific technical features, and does not exclude other possible installation methods.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
