Description

Technical Field

[0001] This invention relates to the field of steel pipe processing technology, specifically to a processing and positioning device for welded steel pipes. Background Technology

[0002] Welded steel pipes, also known as welded pipes, are steel pipes made by rolling and welding steel plates or strips. They are typically available in 6-meter lengths. The production process for welded steel pipes is simple, efficient, and offers a wide variety of specifications with low equipment investment, but their strength is generally lower than that of seamless steel pipes.

[0003] Steel bracing, as a line of defense in a steel structure-bracing system, plays a vital role in the structure. Welded steel pipes, being the most commonly used type of steel bracing, require careful design of their connection nodes, demanding high processing precision. Welded steel pipe supports are often connected to the steel frame beam-column joints as a whole via welding or bolting, using a connecting plate. Before welding the welded steel pipe to the connecting plate, a slit needs to be cut in the center of the welded steel pipe. Because the welded steel pipe is circular, the rolling motion of the pipe during slit cutting often leads to misalignment of the cut, affecting subsequent welding to the connecting plate.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1-2 As shown, a processing and positioning device for a steel structure welded pipe 6 includes a support base 1. The upper end of the support base 1 is provided with a U-shaped support groove 101. A positioning seat 2 is provided within the support groove 101. The positioning seat 2 and the support base 1 slide vertically together, allowing the height to be adjusted according to usage requirements. Figure 4 As shown, the positioning seat 2 includes a base frame 202, with support frames 201 at both ends. Support rods 203 for supporting the welded pipe 6 are connected between the support frames 201 and the base frame 202. The support rods 203 at both ends form a V-shaped structure. The support rods 203 can position welded pipes 6 of different diameters and prevent the welded pipe 6 from rolling. A pipe-pressing mechanism 5 for pressing the welded pipe 6 is connected to both ends of the positioning seat 2. The pipe-pressing mechanism 5 can press and fix the welded pipe 6 to prevent rotation. Additionally, a drive mechanism 3 for conveying the welded pipe 6 is provided at the bottom of the positioning seat 2, which can move the welded pipe 6 forward and backward and adjust the support position. A pipe-lifting mechanism 4 is provided on one side of the support seat 1, which can lift the welded pipe 6 into and out of the positioning seat 2.

[0035] like Figure 3As shown, a guide groove 102 is provided on the side wall of the support groove 101, and a lead screw 103 is provided in the guide groove 102. A worm gear 106 is sleeved at the bottom of the lead screw 103. A worm 105 that cooperates with the worm gear 106 is provided in the support base 1. A first motor 104 connected to the worm 105 is provided on the side wall of the support base 1. A lifting block 204 that slides with the guide groove 102 is connected to the side wall of the support frame 201. The lifting block 204 is threaded with the lead screw 103. The first motor 104 drives the lead screw 103 to rotate. Under the guidance of the guide groove 102, the lifting block 204 moves up and down along the lead screw 103 to realize the lifting and lowering of the positioning seat 2.

[0036] like Figure 5-6 As shown, the bottom of the base frame 202 is provided with a support box 205. The drive mechanism 3 includes a lifting seat 302, which is located inside the support box 205. The lifting seat 302 is provided with a drive wheel 301. A second motor 303 is provided on the side wall of the lifting seat 302 to drive the drive wheel 301 to rotate. A guide strip 206 for positioning the lifting seat 302 is provided on the side wall of the support box 205. A clearance groove 208 is provided for the second motor 303.

The drive wheel 301 drives the welded pipe 6 to move, realizing the forward and backward movement of the welded pipe 6.

[0037] The drive wheel 301 has a concave structure in the middle, which allows the welded pipe 6 to automatically be positioned in the middle of the drive wheel 301 under the action of gravity, ensuring stability and reliability during transportation.

[0038] like Figure 7 As shown, the pipe pressing mechanism 5 includes a first guide rail 501 and a second guide rail 513 fixed on both sides of the support base 1. A first slider 502 is provided on the first guide rail 501, and a second slider 512 is provided on the second guide rail 513. Both the first guide rail 501 and the second guide rail 513 adopt existing linear guide rails (linear slide rails), which can drive the first slider 502 and the second slider 512 to move linearly. A support block 503 is provided on the first slider 502. A rotary cylinder 504 is provided at the upper end of the support block 503. The piston rod of the rotary cylinder 504 is connected to a first pull rod 507. The upper end of the first pull rod 507 is connected to a pressing rod 508 for pressing down the welded pipe 6. A second pull rod 511 is connected to the second slider 512. A pull block 509 is provided at the upper end of the second pull rod 511. A pull groove 510 that cooperates with the pressing rod 508 is provided on one side of the pull block 509.

[0039] During the pressing process, the pressing rod 508 rotates to the top of the welded pipe 6, with the end of the pressing rod 508 located in the pull groove 510. The pressing rod 508 is pulled down by the first pull rod 507 and the second pull rod 511 to press and fix the welded pipe 6. After processing is completed, the pressing rod 508 rotates 90° in the opposite direction and is located on one side of the support seat 1.

[0040] In order to position the opening position of the pressure rod 508, a stop rod 506 parallel to the pressure rod 508 is provided on the side wall of the first pull rod 507, and a limit rod 505 cooperating with the stop rod 506 is provided at the upper end of the rotary cylinder 504.

[0041] like Figure 8-9 As shown, the pipe lifting mechanism 4 includes a crossbeam 402, a first guide rod 107 on one side of the support base 1, a sliding sleeve 403 that cooperates with the first guide rod 107 on one side of the crossbeam 402, a fourth hydraulic cylinder 410 that is fixed to the support base 1 connected to the bottom of the crossbeam 402, a third guide rail 401 on the upper end of the crossbeam 402, a long slider 405 that cooperates with the third guide rail 401, a second hydraulic cylinder 404 that drives the long slider 405 on one side of the third guide rail 401, a support plate 406 on one end of the long slider 405, and a pipe lifting block 407 that lifts the welded pipe 6 connected to the support plate 406.

[0042] The lower end of the lifting block 407 is connected to a second guide rod 408 that passes through the support plate 406. The lower end of the support plate 406 is fixed with a third hydraulic cylinder 409 that is connected to the lifting block 407. The upper end of the lifting block 407 is provided with a V-groove, which can position the welded pipe 6 and ensure stability during transportation.

[0043] like Figure 10-11 As shown, at least two support devices are used to support both ends of the welded pipe 6. During loading, the second hydraulic cylinder 404 pushes the long slider 405, positioning the lifting block 407 on one side of the support base 1. At this time, the crossbeam 402 is at its lowest position. The welded pipe 6 is placed on the lifting block 407, and the crossbeam 402 rises to the uppermost end of the first guide rod 107. Then, the third hydraulic cylinder 409 is activated, raising the lifting block 407 so that the welded pipe 6 is higher than the height of the support base 1. The second hydraulic cylinder 404 pulls the long slider 405 to move, thus moving the welded pipe... The welded pipe 6 is positioned above the positioning seat 2. The crossbeam 402 descends, causing the lifting block 407 to be lower than the positioning seat 2. At this time, the welded pipe 6 is located inside the positioning seat 2. The rotary cylinder 504 is activated, and the pressure rod 508 rotates 90° to the upper end of the welded pipe 6. The end of the pressure rod 508 engages with the pull groove 510. The first pull rod 507 and the second pull rod 511 pull the pressure rod 508 downwards, pressing and fixing the welded pipe 6. At this time, the end of the welded pipe 6 can be cut, welded, or processed. After processing, the pressure rod 508 is reset, and the lifting rod lifts, moves, and lowers the welded pipe 6, moving it from inside the support seat 1 to one side of the support seat 1.
