Description

Technical Field

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

[0002] Pipeline welding construction generally requires auxiliary support frames for support. The pipeline is placed on the auxiliary support frame. Some large pipelines need to be continuously rotated during welding to adapt to the welding position. When the pipeline rotates, the rollers on the support frame can provide rolling support for the pipeline to reduce frictional resistance.

[0003] The rollers of the auxiliary support frame need to bear a very heavy weight during operation, and they often wear out and need to be replaced. Most existing structures lock the rollers with multiple bolts, and when replacing the rollers, a large number of bolts need to be removed repeatedly, which is time-consuming and laborious. Utility Model Content

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

[0005] This utility model provides the following technical solution:

[0006] A pipe welding auxiliary support device includes a base and two symmetrically arranged support components. Each support component includes a first arc-shaped plate, a second arc-shaped plate, and two rollers. The first and second arc-shaped plates are rotatably mounted inside the base, and the two rollers are rotatably mounted between the first and second arc-shaped plates. The device also includes a support component, which includes a support rod and a circular plate. The support rod is slidably inserted between the first and second arc-shaped plates, and the rollers are rotatably sleeved on the outside of the support rod. The circular plate is fixedly mounted at one end of the support rod, and has a plurality of circular holes and a plurality of arc-shaped holes equidistantly spaced around its circumference, with the circular holes and arc-shaped holes communicating with each other.

[0007] The supporting component also includes several T-shaped blocks that are circumferentially and equidistantly fixed on the outside of the first arc-shaped plate. The arc-shaped holes are adapted to the lower half of the T-shaped blocks, and the circular holes are adapted to the upper half of the T-shaped blocks.

[0008] The support rod has several through slots and several limiting slots equidistantly spaced around its circumference at one end away from the circular plate. The through slots and limiting slots correspond one-to-one and are interconnected.

[0009] The supporting component also includes a fixing ring and several limiting blocks. The fixing ring is fixedly installed on one side of the second arc-shaped plate, and the several limiting blocks are circumferentially fixedly arranged inside the fixing ring. The limiting blocks can be engaged in the limiting groove.

[0010] The support assembly also includes an extension block, which is fixedly installed at the end of the support rod away from the circular plate. The extension block has a locking groove and two circular grooves.

[0011] A locking assembly is connected to the second arc-shaped plate. The locking assembly can cooperate with the locking groove and the two circular grooves to restrict the rotation of the support rod.

[0012] The locking assembly includes four L-shaped brackets, a first fixed plate, a square rod, a second fixed plate, a locking block, two round rods, and a spring. The four L-shaped brackets are circumferentially fixedly installed on one side of the second arc-shaped plate. The first fixed plate is fixedly installed between the four L-shaped brackets. The square rod is slidably inserted into the first fixed plate. The second fixed plate is fixedly installed on the side of the square rod facing the second arc-shaped plate. The locking block and the two round rods are both fixedly installed on the side of the second fixed plate facing the second arc-shaped plate. The locking block can be slidably inserted into the locking groove, and the two round rods can be slidably inserted into the two round grooves.

[0013] The locking assembly also includes a rotating plate, a handle, and two arc-shaped blocks. The rotating plate is rotatably mounted on one end of the square rod, the handle is fixedly mounted on the outside of the rotating plate, and the two arc-shaped blocks are symmetrically fixedly mounted on the outside of the first fixed plate. Arc-shaped grooves are provided on the inner sides of the two arc-shaped blocks, and the rotating plate can slide and engage in the arc-shaped grooves.

[0014] The locking block and the locking groove have the same shape, both being hexagonal structures.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] In this invention, when the roller needs to be replaced, the support rod is rotated counterclockwise so that the circular hole on the circular plate corresponds to the T-shaped block, and the through slot corresponds to the limiting block. This unlocks the support rod, which can then be pulled out from between the first and second arc plates, thereby unlocking and replacing the roller, simplifying the disassembly of the support rod.

[0017] In this invention, when installing the support rod, the rotating plate is first slid out of the arc-shaped groove, and the spring will drive the locking block to reset. At this time, the support rod is inserted from one side of the first arc-shaped plate. When the support rod slides, it will drive the extension block to push the two round rods, the second fixing plate, and the locking block to slide outward and compress the spring. After the round plate slides to fit with the first arc-shaped plate, the support rod is rotated clockwise, which can drive the two round grooves on the extension block to rotate to correspond to the two round rods. At this time, the spring will be released and push the second fixing plate, the locking block, and the two round rods to slide towards the extension block, so that the locking block can slide into the locking groove and the two round rods can slide into the two round grooves, thereby locking the support rod and simplifying the operation of installing the support rod.

However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein.

[0027] Figures 1-7 This is the preferred embodiment of the present invention, as described below in conjunction with the appendix. Figure 1 -Appendix Figure 7 The present invention will be further described below.

[0028] A pipe welding auxiliary support device includes a base 1 and two support components 2. The two support components 2 are symmetrically and rotatably installed within the base 1. Each support component 2 includes a first arc-shaped plate 201, a second arc-shaped plate 202, and two rollers 203. The first arc-shaped plate 201 and the second arc-shaped plate 202 are both rotatably installed within the base 1, and the two rollers 203 are both rotatably installed between the first arc-shaped plate 201 and the second arc-shaped plate 202. The device also includes:

[0029] Support component 3 is disposed within support component 2 and is used to support roller 203;

[0030] Locking component 4 is disposed on one side of the second arc-shaped plate 202 and is used to lock the support component 3.

[0031] Specifically, the supporting component 2 also includes several T-shaped blocks 204, which are fixedly installed on one side of the first arc plate 201 at equal intervals around their circumference. The supporting component 3 is rotatably sleeved on the outside of the T-shaped blocks 204. The supporting component 3 includes a supporting rod 301 and a circular plate 302. The supporting rod 301 is slidably inserted between the first arc plate 201 and the second arc plate 202. The circular plate 302 is fixedly installed on the rear end of the supporting rod 301. Several circular holes 303 and several arc-shaped holes 304 are equidistantly opened on the circumference of the circular plate 302.

[0032] In this embodiment, the arc-shaped hole 304 is adapted to the lower half of the T-shaped block 204, and the circular hole 303 is adapted to the upper half of the T-shaped block 204. When the lower half of the T-shaped block 204 is inside the arc-shaped hole 304, the upper half of the T-shaped block 204 can limit the circular plate 302. In the initial state, the lower half of the T-shaped block 204 is at the end of the arc-shaped hole 304.

[0033] Specifically, the supporting component 2 also includes a fixing ring 205 and several limiting blocks 206. The fixing ring 205 is fixedly installed on one side of the second arc plate 202. Several limiting blocks 206 are fixedly installed circumferentially within the fixing ring 205. The limiting blocks 206 can be snapped into the supporting component 3. Several through grooves 305 are equidistantly opened on the front end circumference of the supporting rod 301, and several limiting grooves 306 are equidistantly opened on the outer circumference of the supporting rod 301. The limiting grooves 306 are connected to the through grooves 305.

[0034] In this embodiment, both the groove 305 and the limiting groove 306 are adapted to the limiting block 206. In the initial state, the limiting block 206 is located in the limiting groove 306.

[0035] Specifically, the locking assembly 4 includes four L-shaped brackets 401, a first fixing plate 402, a square rod 403, a second fixing plate 404, a locking block 405, two round rods 406, and a spring 407. The four L-shaped brackets 401 are circumferentially fixedly installed on one side of the second arc-shaped plate 202. The first fixing plate 402 is fixedly installed between the four L-shaped brackets 401. The square rod 403 is slidably installed inside the first fixing plate 402. The second fixing plate 404 is fixedly installed on the side of the square rod 403 facing the second arc-shaped plate 202. The locking block 405 and the two round rods 406 are both fixedly installed on the side of the second fixing plate 404 facing the second arc-shaped plate 202. The support assembly 3 also includes an extension block 307, which is fixedly installed on the other end of the support rod 301. The extension block 307 has a locking groove 308 and two round grooves 309.

[0036] In this embodiment, the locking block 405 is adapted to the locking groove 308, and the round rod 406 is adapted to the round groove 309. In the initial state, the locking block 405 is in the locking groove 308, the round rod 406 is in the round groove 309, and the spring 407 is in the released state, pushing the second fixing plate 404 to fit with the extension block 307.

[0037] Specifically, the locking assembly 4 also includes a rotating plate 408, a handle 409, and two arc-shaped blocks 410. The rotating plate 408 is rotatably mounted on the outside of the square rod 403, the handle 409 is fixedly mounted on the outside of the rotating plate 408, and the two arc-shaped blocks 410 are symmetrically fixedly mounted on the outside of the first fixed plate 402. Each of the two arc-shaped blocks 410 has an arc-shaped groove 411, and the rotating plate 408 is adapted to the arc-shaped groove 411.

[0038] In this embodiment, in the initial state, the rotating plate 408 is attached to the first fixed plate 402.

[0039] Working principle: When the roller 203 needs to be replaced, pull the handle 409, rotating plate 408, square rod 403, and second fixed plate 404 outward. This compresses the spring 407 and simultaneously disengages the locking block 405 from the locking groove 308. Then, rotate the handle 409, causing the rotating plate 408 to rotate into the two arc-shaped grooves 411. Under the action of the spring 407, the rotating plate 408 can temporarily stop within the arc-shaped grooves 411, thus temporarily fixing the positions of the rotating plate 408, square rod 403, second fixed plate 404, and locking block 405. At this time, rotate the support rod 301 counterclockwise. Figure 2 (View angle), rotate the circular hole 303 on the circular plate 302 to correspond to the T-shaped block 204, and at the same time rotate the through groove 305 to correspond to the limiting block 206, so that the support rod 301 can be unlocked. At this time, the support rod 301 can be pulled out from between the first arc plate 201 and the second arc plate 202, thereby unlocking and replacing the roller 203;

[0040] When installing the support rod 301, first slide the rotating plate 408 out of the arc-shaped groove 411. At this time, the spring 407 is released, which will push the second fixed plate 404 and the locking block 405 to reset, and move the rotating plate 408 to fit against the first fixed plate 402. Then, insert the support rod 301 from one side of the first arc-shaped plate 201, so that the round hole 303 passes through the T-shaped block 204 and slides the round plate 302 to fit against the first arc-shaped plate 201. At this time, the limiting block 206 will enter the through groove 305. When the support rod 301 slides, it will drive the extension block 307 to contact the two round rods 406. At this time, the two round grooves 309 on the extension block 307 are misaligned with the two round rods 406. The extension block 307 will push the two round rods 406. The second fixing plate 404 and the locking block 405 slide outward and compress the spring 407. After the circular plate 302 slides to fit against the first arc plate 201, the support rod 301 is rotated clockwise. The limiting block 206 enters the limiting groove 306, and the lower half of the T-shaped block 204 is in the arc hole 304 and finally enters its end. At the same time, the support rod 301 drives the two circular grooves 309 on the extension block 307 to rotate to correspond with the two circular rods 406. At this time, the spring 407 will be released and push the second fixing plate 404, the locking block 405 and the two circular rods 406 to slide towards the extension block 307, so that the locking block 405 slides into the locking groove 308 and the two circular rods 406 slide into the two circular grooves 309, thereby locking the support rod 301.
