Description

Technical Field

[0001] This utility model relates to the field of welded pipe positioning technology, and in particular to a welded pipe positioning bracket. Background Technology

[0002] In industries such as petroleum, chemical, construction, and power, welded pipes serve as core components for transporting media and constructing structures. The core prerequisite for welded pipe welding operations is to achieve stable and precise positioning of the welded pipes. Currently, the mainstream positioning methods for welded pipes in the industry still rely on traditional clamps or simple supports. Most of them adopt fixed clamping structures, which can only match welded pipes of a single specification diameter. When facing the need to connect welded pipes of different diameters, it is necessary to frequently disassemble and replace the corresponding clamps, which not only increases equipment procurement costs but also causes welding operations to be interrupted, significantly reducing production efficiency. Furthermore, circumferential welding operations are cumbersome, and existing supports do not consider the need for welding pipes around the entire circumference. After completing the welding of a certain angle, it is necessary to first disassemble the positioning structure, adjust the angle of the welded pipe, and then re-clamp and position it. This process is prone to positioning deviations, and the operation steps are cumbersome, extending the welding cycle of a single welded pipe.

[0003] Therefore, it is necessary to provide a new welded pipe positioning bracket to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a welded pipe positioning bracket.

[0005] The welded pipe positioning bracket provided by this utility model includes an L-shaped angle steel. A groove is provided in the middle of the upper plate of the L-shaped angle steel, and support components are installed on both sides of the L-shaped angle steel of the groove.

[0006] The support component includes a mounting rod, both ends of which are equipped with rotatably connected support wheels, and the mounting rod is fixedly mounted on an L-shaped angle steel by a bracket;

[0007] The L-shaped angle steel is also equipped with abutting components for abutting the welded pipe, and the abutting components include a threaded rod. The head of the threaded rod is equipped with a centrally connected square tube, and two sets of symmetrically distributed curved frames are fixedly installed on the centrally connected square tube. Each of the curved frames is equipped with a rotating shaft that is rotatably connected, and abutting wheels are fixedly sleeved at both ends of the rotating shaft.

[0008] Preferably, the lower plate of the L-shaped angle steel is fixedly installed with a support frame, and a threaded cylinder corresponding to the cut groove is fixedly installed on the support frame.

[0009] Preferably, the threaded rod passes through the threaded cylinder and is threadedly connected to the threaded cylinder, and a knob is fixedly installed at the end of the threaded rod.

[0010] Preferably, two symmetrically distributed limiting rods are fixedly welded onto the central square tube, and the two limiting rods pass through the limiting holes opened in the support frame and are slidably connected to the limiting holes.

[0011] Preferably, the upper and lower plates of the L-shaped angle steel are each provided with two sets of symmetrically distributed support components.

[0012] Preferably, the support wheels located on the upper plate of the L-shaped angle steel are coaxially arranged, and the support wheels located on the lower plate of the L-shaped angle steel are coaxially arranged.

[0013] Compared with related technologies, the welded pipe positioning bracket provided by this utility model has the following advantages:

[0014] 1. This utility model uses a mating component that engages with a threaded rod and a threaded cylinder to drive the central square tube to flexibly adjust the spacing of the mating wheel in the vertical (or horizontal) direction. Combined with the support wheels symmetrically arranged on the upper and lower plates of the L-shaped angle steel, it can achieve clamping and positioning of welded pipes of different diameters. Moreover, no parts need to be replaced, and the adjustment can be completed simply by rotating the knob, which greatly reduces equipment costs and is suitable for industrial welding scenarios of multiple specifications of welded pipes.

[0015] 2. The present invention uses a support wheel and abutment wheel to form a three-point fixing structure of lower support + side support + lateral abutment, which effectively avoids the lateral displacement and axial movement of the welded pipe during the welding process. In addition, both the support wheel and the abutment wheel are designed to rotate. After the weld at a certain angle is completed, the welded pipe can be rotated directly to drive the support wheel and the abutment wheel to rotate synchronously without disassembling the positioning structure, thus avoiding the deviation and time consumption of repositioning.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 4 The present invention provides a welded pipe positioning bracket, which includes an L-shaped angle steel 1, a supporting component 2, and an abutting component 3.

[0024] In the embodiments of this utility model, please refer to Figures 1 to 4 The upper plate of the L-shaped angle steel 1 has a groove 1a in the middle, and support components 2 are installed on both sides of the L-shaped angle steel 1. Specifically, the upper plate and the lower plate of the L-shaped angle steel 1 are provided with two sets of symmetrically distributed support components 2. The support component 2 includes a mounting rod 21. Both ends of the mounting rod 21 are equipped with rotatably connected support wheels 22. The mounting rod 21 is fixedly installed on the L-shaped angle steel 1 by a bracket. The support wheels 22 located on the upper plate of the L-shaped angle steel 1 are coaxially arranged, and the support wheels 22 located on the lower plate of the L-shaped angle steel 1 are coaxially arranged.

[0025] It should be noted that when welding the two pipes, the two pipes are placed on the L-shaped angle steel 1 respectively, and the welding head is kept at the cut groove 1a. Therefore, the two support wheels 22 of the upper plate support component 2 of the L-shaped angle steel 1 can play a resisting role for the pipe, while the two support wheels 22 of the lower plate support component 2 of the L-shaped angle steel 1 can play a supporting role for the pipe.

[0026] The lower plate of the L-shaped angle steel 1 is fixedly equipped with a support frame 11, and a threaded cylinder 12 corresponding to the groove 1a is fixedly installed on the support frame 11. The L-shaped angle steel 1 is also equipped with an abutting component 3 for abutting the welded pipe. The support frame 11 is set at the bottom of the L-shaped angle steel 1 to improve the stability of the L-shaped angle steel 1, and to install the abutting component 3. At the same time, it can also prevent the support wheel 22 on the lower plate of the L-shaped angle steel 1 from being restricted by the ground.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 4 The abutting component 3 includes a threaded rod 31, the head of which is mounted with a central square tube 32 that is rotatably connected. Two sets of symmetrically distributed curved frames 33 are fixedly mounted on the central square tube 32. Each curved frame 33 is fitted with a rotatably connected rotating shaft 34, and both ends of the rotating shaft 34 are fixedly fitted with abutting wheels 35. The threaded rod 31 passes through the threaded cylinder 12 and is threadedly connected to the threaded cylinder 12. Two symmetrically distributed limiting rods 36 are fixedly welded to the central square tube 32, and the two limiting rods 36 pass through the limiting holes 11a opened in the support frame 11 and are slidably connected to the limiting holes 11a.

[0028] It should be noted that after the two welded pipes are placed, the rotating threaded rod 31 drives the abutment wheel 35 to move in the direction of the welded pipe placement until the abutment wheel 35 firmly abuts the welded pipes. Therefore, the two welded pipes are firmly clamped and positioned by the upper and lower plate support wheels 22 of the L-shaped angle steel 1 and the abutment wheel 35, preventing them from moving laterally. Subsequently, the workers can use the welding torch to weld the joint of the two welded pipes at the groove 1a. After the weld is completed at this point, rotating either welded pipe will drive both welded pipes to rotate so that the unwelded parts can be welded.

[0029] Therefore, in this application, the abutting component 3, through the threaded engagement of the threaded rod 31 and the threaded cylinder 12, can drive the central square tube 32 to flexibly adjust the spacing of the abutting wheel 35 vertically (or horizontally). Combined with the symmetrically arranged support wheels 22 on the upper and lower plates of the L-shaped angle steel 1, it can achieve clamping and positioning of welded pipes of different diameters without replacing any parts; adjustment can be completed simply by rotating the knob 311, significantly reducing equipment costs and adapting to industrial multi-specification welded pipe welding scenarios. The support wheels 22 on the upper plate of the L-shaped angle steel 1 provide horizontal support to the top of the welded pipe. The lower plate's support wheel 22 provides support to the bottom of the welded pipe, while the abutment wheel 35 provides clamping force from the vertical (or inner) side, forming a three-point fixing structure of lower support + side support + lateral abutment. This effectively prevents the welded pipe from shifting laterally and moving axially during welding. Furthermore, both the support wheel 22 and the abutment wheel 35 are designed for rotational connection. After welding at a certain angle, simply rotating the welded pipe will drive the support wheel 22 and the abutment wheel 35 to rotate synchronously without disassembling the positioning structure, thus avoiding the deviation and time consumption of repositioning.

[0030] A knob 311 is fixedly installed at the end of the threaded rod 31 to facilitate rotation of the threaded rod 31.
