Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline welding, in particular to a supporting device for pipeline welding. Background Art

[0002] Pipe welding supports are devices used to support and secure pipes during welding to ensure welding quality and safety. Pipe clamps secure both ends of the pipe to prevent displacement or deformation during welding. Common types include single-sided and double-sided clamps. Because the support position of the support device in related technologies is difficult to adjust, the pipes cannot be accurately aligned, resulting in weld misalignment. Furthermore, the instability of the support device in related technologies can cause the pipes to shift or wobble during welding. Defects such as misalignment, slag inclusions, and lack of fusion may occur in the weld, seriously affecting welding quality and even requiring rework. Summary of the Invention

The two fixed bases 201 are symmetrically arranged on the upper end surface of the base plate 101. The movable slide 601 slides with the two fixed bases 201, and the end of the movable slide 601 is connected to the fixed base 201 via a fastening mechanism 602. The bottom of the support base 603 is connected to the upper end surface of the movable slide 601, and the top of the support base 603 is connected to the pipe clamping mechanism. The two limit support mechanisms are symmetrically arranged on the upper end surface of the base plate 101, and the two limit support mechanisms are located between the two fixed bases 201. The limit support mechanisms are used to press and position the sides of the support base 603. The side end surface of the fixed base 201 is provided with a slide groove 202. One end of the fastening mechanism 602 slides with the slide groove 202, and the other end of the fastening mechanism 602 is used to lock and fix the movable slide 601. The movable slide 601 slides freely along the chute 202 on the fixed base 201, facilitating adjustment of the pipe support position. This significantly enhances the device's flexibility, enabling rapid adaptation to varying welding conditions and reducing adjustment time and complexity. The movable slide 601 is connected to the fixed base 201 via a fastening mechanism 602, ensuring a secure lock once adjusted to the desired position, preventing displacement. This prevents the pipe from shaking or shifting during welding, thereby improving operational safety and weld quality.

[0031] The fastening mechanism 602 includes a guide rod, a limit block, a locking nut and an anti-slip pad. The inner end of the guide rod slides with the slide groove 202 through the limit block, and the outer end of the guide rod passes through the end of the movable slide 601. The guide rod is connected and fixed between the fixed base 201 and the movable slide 601 through the locking nut.

The inner sides of the upper clamping plate 502 and the lower clamping plate 501 can both cooperate with the pipe. The upper clamping plate 502 and the lower clamping plate 501 are connected and fixed by multiple locking structures 701. Two spring bases 802 are provided in the middle of the inner side of the lower clamping plate 501, and rollers are provided on the top of the spring base 802. The two strip-shaped positioning blocks 801 are symmetrically arranged on the inner side of the lower clamping plate 501, and the anti-slip structure is provided on the inner side of the upper clamping plate 502. The anti-slip structure includes multiple anti-slip rubber blocks, which are arranged circumferentially on the inner side of the upper clamping plate 502. The locking structure 701 includes a threaded rod and two locking nuts. The threaded rod passes through the ends of the upper clamping plate 502 and the lower clamping plate 501, and the two locking nuts are symmetrically arranged at the upper and lower ends of the threaded rod.

[0033] like Figure 2As shown, the position limiting support mechanism includes a positioning base 301, an adjusting screw 401, a compression spring 402, and a positioning claw 403. The bottom of the positioning base 301 is detachably connected to the base plate 101, the top of the positioning base 301 is threadedly engaged with the adjusting screw 401, the inner end of the adjusting screw 401 is rotatably connected to the positioning claw 403, and the positioning claw 403 can cooperate with the support base 603. The compression spring 402 is provided on the adjusting screw 401 and is located between the positioning base 301 and the positioning claw 403. The position limiting support structure effectively prevents the movable slide 601 and the support base 603 from shaking and displacement during operation by compressing and positioning the side of the support base 603.
