Description

Technical Field

[0001] This utility model relates to the field of support component technology, and in particular to a support component for repairing weld seams of stainless steel welded pipes. Background Technology

[0002] Welded pipe supports are commonly used to support pipes during the welding process, especially when repairing welds. These supports ensure the stability of the weld position during welding and provide support for welders. They are typically made of materials such as stainless steel to ensure corrosion resistance and long-term stability. Nowadays, improper transportation or storage of stainless steel welded pipes can easily lead to cracks at the weld seams. Therefore, it is necessary to position and support the stainless steel welded pipes with support components so that workers can repair the cracks and prevent them from affecting subsequent use.

[0003] However, existing support components are often difficult to apply to welded pipes of different shapes during the support process, which limits their applicability. At the same time, since some welded pipes are in a bent state, the bending angle varies, which increases the difficulty of support components and affects the repair of weld seams on welded pipes. In view of this, we propose a support component for repairing weld seams on stainless steel welded pipes. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background art by proposing a support component for repairing weld seams of stainless steel welded pipes.

[0005] The technical solution of this utility model is as follows: A support assembly for repairing weld seams of stainless steel welded pipes includes a workbench. A first bracket and a second bracket are arranged on the top wall of the workbench to facilitate support of the stainless steel welded pipe. Positioning plates are welded to one side wall of both the first and second brackets. Locking mechanisms for positioning the welded pipe are arranged on the other side wall of both the first and second brackets. Guide rails for assisting the movement of the locking mechanisms are installed on the other side wall of both the first and second brackets. A limit slider is welded to the bottom wall of the first bracket. A cylinder for moving the limit slider is installed on the front-facing wall of the top plate of the workbench. A driven mechanism for rotating the second bracket is provided on the bottom wall of the second bracket. A driving mechanism for rotating the driven mechanism is installed on the top of the bottom plate of the workbench.

[0006] Preferably, the locking mechanism includes an arc-shaped clamp, a movable rod is welded to one side wall of the arc-shaped clamp, a hinge seat is hinged to the movable rod, and an anti-detachment slider is welded to one side wall of the hinge seat.

[0007] Preferably, the positioning plate has a first threaded hole, and an auxiliary plate is welded to the other side wall of the arc-shaped clamp. The auxiliary plate has a second threaded hole, and a screw is installed in the second threaded hole.

[0008] Preferably, an anti-slip groove is provided on one side wall of the guide rail, and the anti-slip slider is disposed in the anti-slip groove.

[0009] Preferably, the driven mechanism includes a second rotating shaft, on the outer ring surface of which a driven gear and a bearing are fitted, and the top end of the second rotating shaft is welded to the bottom wall of the second bracket.

[0010] Preferably, the drive mechanism includes a forward and reverse motor, the output end of which is connected to a first rotating shaft, and a bearing seat is connected to the top end of the first rotating shaft. The bearing seat is mounted on the bottom wall of the top plate of the workbench.

[0011] Preferably, a drive gear is fitted onto the outer ring surface of the first rotating shaft, and the drive gear meshes with the driven gear.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] This invention uses a forward and reverse motor to drive a first rotating shaft, which in turn drives a drive gear. This, in turn, causes a driven gear to rotate a second rotating shaft, thus adjusting the angle of the second support. Simultaneously, a cylinder is used to adjust the position of the first support. This allows the first and second supports to support welded pipes with varying degrees of curvature, expanding the applicability of the equipment and facilitating subsequent welded pipe support and maintenance. Furthermore, a flip-locking mechanism tightens screws into the first threaded hole on the positioning plate, enabling the welded pipe to be positioned with the aid of an arc-shaped clamp. This prevents the welded pipe from moving during weld repair, thus avoiding disruption to the repair work. Attached Figure Description

[0021] Furthermore, locking mechanisms 4 for facilitating the positioning of the welded pipe are arranged on the other side wall of both the first support 2 and the second support 9. Each locking mechanism 4 includes an arc-shaped clamp 41, with a movable rod 43 welded to one side wall of the arc-shaped clamp 41. The opening of the movable rod 43 is hinged to a hinge seat 42, allowing the movable rod 43 to be driven by the hinge seat 42 to rotate the arc-shaped clamp 41. After rotation, the arc-shaped clamp 41 can cooperate with the groove on the first support 2 or the second support 9 to clamp and limit the welded pipe, preventing it from moving during maintenance and affecting the safe operation of the maintenance work. An anti-detachment slider 44 is welded to one side wall of the hinge seat 42, and a guide rail 10 is welded to the other side wall of both the first support 2 and the second support 9. The anti-detachment slider 44 is set in the anti-detachment groove opened on one side wall of the guide rail 10, which allows the locking mechanism 4 to move as a whole under the cooperation of the anti-detachment slider 44 and the guide rail 10.

The auxiliary plate 45 is fixedly installed on the other side wall of the arc-shaped clamp 41, and the screw 46 is set in the second threaded hole opened on the auxiliary plate 45. Due to the multiple first threaded holes opened on the positioning plate 3, the arc-shaped clamp 41 in the clamping state can achieve the purpose of locking the position of the arc-shaped clamp 41 under the cooperation of the screw 46 and the first threaded hole, so as to prevent the arc-shaped clamp 41 from moving during the clamping process and affecting the clamping and positioning of the welded pipe.

[0022] Furthermore, a driven mechanism 5 is provided at the bottom wall of the second support 9 to facilitate the rotation of the second support 9. The driven mechanism 5 includes a second rotating shaft 51. A rotating opening is provided on the top plate of the workbench 1. The bearing and the driven gear 52 are both sleeved on the outer ring surface of the second rotating shaft 51. The bearing is located in the rotating opening, and its outer ring surface is connected to the inner ring surface of the rotating opening. The top of the second rotating shaft 51 is fixedly connected to the bottom wall of the second support 9, which facilitates the rotation of the second support 9 by the bearing assisting the second rotating shaft 51. This is beneficial for supporting welded pipes with different bending angles through the rotating second support 9. The driven gear 52 is located below the top plate of the workbench 1 to facilitate the subsequent provision of power for the rotation of the second rotating shaft 51.

[0023] Furthermore, a drive mechanism 6 is installed at the top of the base plate of the workbench 1 to facilitate the rotation of the driven mechanism 5. The drive mechanism 6 includes a forward and reverse motor 61, which is fixedly installed on the top wall of the base plate of the workbench 1. The bottom end of the first rotating shaft 62 is connected to the output end of the forward and reverse motor 61. The bearing seat 63 is fixedly installed on the bottom wall of the top plate of the workbench 1, and its rotating end is connected to the output end of the forward and reverse motor 61, so that the first rotating shaft 62 can be driven to rotate by the forward and reverse motor 61. The driving gear 64 is fixedly sleeved on the outer ring surface of the first rotating shaft 62 and meshes with the driven gear 52, so that the first rotating shaft 62 drives the driving gear 64 to rotate, providing power to the driven gear 52. Under the transmission of the driven gear 52, the second rotating shaft 51 drives the second support 9 to rotate, which facilitates the support of the bent stainless steel welded pipe, improves the applicability of this equipment, and is beneficial for repairing the weld seam of welded pipes with different bending angles.
