Description

Technical Field

[0001] The utility model relates to the field of pipeline cutting and processing, and particularly relates to a pipeline scribing bracket tooling. Background Technique

[0002] In the iron and steel industry, especially in the chemical industry, pipelines account for more than 60% of production equipment. During production maintenance and transformation, it is essential to cut the pipelines during pipeline transformation, and the workload is large and the requirements are high. At the same time, during pipeline welding, the quality of cutting directly affects the welding quality and speed, and the scribing work during cutting plays an important role, which directly affects the quality and speed of cutting.

[0003] Chinese patent document CN218698758U (202222345632.4) discloses a scribing tool for HVAC pipeline installation, including a base. However, the guide plate of this scribing tool is fixedly arranged on the base and cannot be applied to scribing pipelines of different lengths. Utility Model Content

[0004] The purpose of the utility model is to provide a pipeline scribing bracket tooling. Both the first rotating bracket and the second rotating bracket are provided with V-shaped grooves with openings upward on the support plate. By placing the pipeline above the surface of the rotating support wheel located in the V-shaped groove and installing a scribing device in the fixed groove, pipelines of different diameters are scribed using the scribing connecting rod. Since the first rotating bracket and the second rotating bracket of the utility model are separately arranged, the distance between the first rotating bracket and the second rotating bracket can be adjusted according to the length of the pipeline to be cut, which is applicable to scribing operations of pipelines of different lengths.

[0005] The technical problem to be solved by the utility model is realized by the following technical solution: A pipeline scribing bracket tooling, including a first rotating bracket, a second rotating bracket, a rotating support wheel and a scribing connecting rod;

[0006] Both the first rotating bracket and the second rotating bracket include a support plate, and the support plate is provided with a V-shaped groove with an opening upward;

[0007] The two sides of the V-shaped groove are symmetrically provided with rotating support wheels, the rotating support wheels are rotatably arranged on the support plate, and the surface of the rotating support wheel is higher than the side wall of the V-shaped groove;

[0008] The middle of the scribing connecting rod is hinged to the first rotating bracket, and the scribing connecting rod is located above the V-shaped groove;

[0009] The end of the scribing connecting rod is provided with a fixed groove for fixing the scribing device.

[0010] Preferably, the utility model further includes a diameter adjusting rod;

[0011] The diameter adjusting rod is movably arranged on the support plate along its own axis, and the axis of the diameter adjusting rod intersects with the center line of the V-shaped groove;

[0012] The rotating support wheel is rotatably arranged at the end of the diameter adjusting rod. Since the diameters of the pipes are different, by movably arranging the diameter adjusting rod on the support plate along its own axis, the distance between the two rotating support wheels on the same support plate can be adjusted, which is applicable to laying pipes with different diameters.

[0013] Preferably, the axis of the diameter adjusting rod is perpendicular to the side wall of the V-shaped groove in the present utility model.

[0014] Preferably, a long adjusting hole is arranged in the middle of the diameter adjusting rod, and at least two bolt connection holes are arranged on the support plate. The adjusting hole is connected to the two bolt connection holes through fasteners. The long adjusting hole can connect bolt connection holes with different spacings or enable the diameter adjusting rod to slide along its own axis, thereby adjusting the position of the rotating support wheel on the support plate. Connecting the adjusting hole to the two bolt connection holes through fasteners can ensure the stability of the diameter adjusting rod and avoid the shaking during the rotation of the pipe from affecting the scribing accuracy.

[0015] Preferably, the present utility model further includes a height adjusting rod, which is vertically arranged on the first rotating bracket, and the scribing connecting rod is hinged to the upper end of the height adjusting rod;

[0016] The length of the height adjusting rod is adjustable. The height of the scribing connecting rod is adjusted by using the height adjusting rod to meet the scribing requirements of pipes with different diameters and satisfy the scribing requirements of pipes with larger diameter sizes.

[0017] Preferably, the height adjusting rod is a telescopic rod in the present utility model.

[0018] Preferably, the scribing device is a piece of chalk or a marker pen in the present utility model.

[0019] Preferably, the rotating support wheel is a bearing or a rubber wheel in the present utility model. The bearing has small resistance and is more convenient for rotating the pipe; while the rubber wheel is cheaper and more wear-resistant.

[0020] Preferably, the present utility model further includes a cutting device arranged on the first rotating bracket, and the cutting device is located above the V-shaped groove. By arranging the cutting device on the first rotating bracket, after scribing is completed, the pipe can be directly cut, which is more convenient.

[0021] Preferably, the cutting device includes a cutting torch, and the cutting torch is detachably installed on the scribing connecting rod. The cutting torch is fixed by using the scribing connecting rod to ensure that the cutting position is aligned with the scribing position.

[0022] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model utilizes the separately arranged first rotating bracket and second rotating bracket to realize the erection and rotation of pipelines, and is applicable to pipelines of different rectangles.

[0023] Both the first rotating bracket and the second rotating bracket are provided with V-shaped grooves with upward openings on the support plate. By placing the pipeline above the surface of the rotating support wheels located in the V-shaped grooves, the rotation of the pipeline can be realized.

[0024] Since the scribing connecting rod is hinged in the middle to the first rotating bracket and is located above the V-shaped groove, a scribing device is installed in the fixing groove at the end of the scribing connecting rod. By pressing down the scribing device with the scribing connecting rod, scribing can be realized on the surface of the rotating pipeline, and it is applicable to pipelines of different diameters.
