Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and more specifically, to a pipe welding auxiliary bracket. Background Technology

[0002] A pipeline is a system of pipes, pipe fittings, valves, and other components used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transport of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] When welding pipes, two pipes need to be joined together. Currently, small-diameter pipes can be joined by hand, but it is difficult to ensure that two pipes with larger diameters can be accurately joined, which makes welding inconvenient and affects the connection speed. To address this, a pipe welding auxiliary bracket is provided. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pipe welding auxiliary bracket, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a pipe welding auxiliary bracket, including a connecting block, wherein a positioning component is provided on the connecting block; The positioning component includes an adjustment block disposed on the top of the connecting block, and adjustable deflection rods are respectively disposed on both sides of the adjustment block, and a first abutment block is rotatably connected to the bottom end of each deflection rod. One end of each of the first abutment blocks is rotatably connected to an adjusting rod, and a second abutment block is threadedly connected to the outer side of each adjusting rod.

[0006] Optionally, in a possible implementation, the outer sides of the two deflection rods are respectively provided with sliding grooves, and extension frames are fixedly provided at both ends of the connecting block. The two extension frames extend to the outer sides of the corresponding deflection rods, and each extension frame is provided with a sliding rod. The sliding rods are inserted into the extension frames, and each sliding rod extends into the corresponding sliding groove and is slidably connected to the sliding groove. A lead screw is threaded to the middle of the adjusting block, and the bottom end of the lead screw extends to the top of the connecting block and is rotatably connected to the connecting block. The two deflection rods are arranged opposite to each other, and the bottom vertical cross-section of each deflection rod is set to be arc-shaped.

[0007] The technical effects and advantages of this utility model are as follows: The threaded engagement between the adjusting block and the lead screw drives the deflecting rods on both sides to deflect synchronously. The arc-shaped design at the bottom allows for a tight fit against the outer wall of the pipe, achieving a wraparound positioning for pipes of different diameters. The first contact block is rotatably connected to the deflecting rod, allowing for adaptive angle adjustment based on the pipe's curvature, preventing pipe damage caused by rigid contact. Simultaneously, the threaded connection between the adjusting rod and the second contact block allows for axial adjustment of the lifting position along the pipe, adapting to pipes of different lengths or interface positions, significantly improving the device's versatility. The sliding rod and the sliding groove of the deflection rod in the extension frame form a sliding guide structure. When the lead screw drives the adjusting block to move up and down, the sliding rod slides in the sliding groove to ensure the consistency and stability of the deflection angle of the deflection rod and avoid pipe displacement caused by structural loosening.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] As attached Figures 1-4 The pipe welding auxiliary bracket shown, through the positioning component on the connecting block 1 and the threaded engagement between the adjusting block 2 and the lead screw 10, can drive the deflection rods 3 on both sides to deflect synchronously. Its bottom arc design can closely fit the outer wall of the pipe, achieving a ring-shaped positioning for pipes of different diameters. The first contact block 4 is rotatably connected to the deflection rod 3, which can adaptively adjust the angle according to the curvature of the pipe, avoiding pipe damage caused by hard contact; at the same time, the threaded connection structure between the adjusting rod 5 and the second contact block 6 can adjust the lifting position along the pipe axis, adapting to pipes of different lengths or interface positions, significantly improving the versatility of the device, and the specific structural settings of the components are as follows; The positioning component includes an adjusting block 2 set on the top of the connecting block 1, and adjustable deflection rods 3 are respectively set on both sides of the adjusting block 2, and the bottom end of each deflection rod 3 is rotatably connected to a first abutment block 4. One end of each of the multiple first contact blocks 4 is rotatably connected to an adjusting rod 5, and the outer side of each adjusting rod 5 is threadedly connected to a second contact block 6.

[0016] Specifically, as shown in the attached document Figure 1 , 2 As shown in Figure 3, the vertical displacement of the adjusting block 2 causes the deflection rod 3 to deflect at both ends of the connecting block 1, thereby realizing the function of adjusting the angle of the deflection rod 3 so that the two deflection rods 3 can approach each other to clamp the pipe. At the same time, after the pipe is fixed on the equipment, the operator holds the second abutment block 6 and then rotates the adjusting rod 5. The adjusting rod 5 is threadedly connected to the second abutment block 6, thereby realizing the function of adjusting the position of the second abutment block 6 so as to support the pipe at different positions and ensure the stability of the pipe support. The outer sides of the two deflection rods 3 are respectively provided with sliding grooves 7. Both ends of the connecting block 1 are fixedly provided with extension frames 8. The two extension frames 8 extend to the outer side of the corresponding deflection rods 3, and each extension frame 8 is provided with a sliding rod 9. The sliding rod 9 is inserted into the extension frame 8, and each sliding rod 9 extends into the corresponding sliding groove 7 and is slidably connected to the sliding groove 7. The middle part of the adjusting block 2 is threadedly connected with a lead screw 10. The bottom end of the lead screw 10 extends to the top of the connecting block 1 and is rotatably connected to the connecting block 1. The two deflection rods 3 are arranged opposite to each other, and the bottom vertical cross-section of each deflection rod 3 is set to be arc-shaped. Specifically, as shown in the attached document Figure 1 , 2 As shown in Figure 4, the sliding groove 7 and sliding rod 9 are designed to allow the adjusting block 2 to be adjusted up and down at the top of the deflection rod 3 by rotating the screw 10. This allows the deflection rod 3 to be adjusted in angle by the corresponding cooperation of the sliding groove 7 and sliding rod 9 when the adjusting block 2 is displaced, thus facilitating the clamping of the pipe. The specific working principle is as follows: In the initial state, the screw 10 is rotated to drive the adjusting block 2 to move upward. Due to the limiting effect of the slide rod 9 in the slide groove 7, the deflecting rods 3 on both sides open outward with the slide rod 9 as the fulcrum, forming a larger clamping opening. The pipe to be welded is placed between the two first contact blocks 4. The screw 10 is rotated in the opposite direction, and the adjusting block 2 moves downward, pushing the deflecting rod 3 to deflect inward along the slide groove 7 until the arc surface of the first contact block 4 is tightly attached to the outer wall of the pipe. At this time, the sliding trajectory of the slide rod 9 in the slide groove 7 limits the deflection angle of the deflecting rod 3, ensuring that the clamping force on both sides is uniform and preventing the pipe from tilting.

[0017] Once the pipe is fixed, if the support position needs to be adjusted, the adjusting rod 5 can be manually rotated. Since the adjusting rod 5 and the second contact block 6 are threadedly connected, the second contact block 6 moves axially along the adjusting rod 5 during rotation until its top presses against the designated position below the pipe. The rotating connection design between the first contact block 4 and the adjusting rod 5 allows the second contact block 6 to automatically adjust its angle according to the pipe's curvature, ensuring that the support surface is completely in contact with the outer wall of the pipe and avoiding local stress concentration. For pipes of different diameters, simply adjust the opening angle of the deflection rod 3 through the screw 10, and adjust the length of the adjusting rod 5 to achieve quick adaptation without replacing any parts.

[0018] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
