Description

Technical Field

[0001] The present invention relates to the technical field of steel structure buildings, and in particular to a steel pipe bundle assembly device and method for steel structure buildings. Background Art

[0002] A steel pipe bundle is a composite component made up of multiple steel pipes connected by welding or bolting. In steel structure buildings, steel pipe bundles are often used as the main load-bearing and lateral force resisting components, and their assembly quality and efficiency directly affect the safety and construction period of the entire building.

[0003] Currently, the traditional assembly of steel pipe bundles generally involves laying multiple steel pipes flat on the ground and welding them manually or using auxiliary devices. The manual welding assembly method is not only inefficient, but the steel pipe bundles, which are not fully secured, may shift during welding, resulting in poor welding quality and affecting the overall load-bearing capacity of the steel pipe bundle. Traditional auxiliary devices mostly use a movable clamp to clamp the steel pipe bundles for welding. Although this method can fix the steel pipe bundles, it is difficult to adjust the position of the steel pipe bundles. The process of aligning two steel pipes often takes a lot of time, which makes the assembly efficiency of steel pipe bundles low and slows down the construction cycle of the entire building.

[0032] Please see Figures 1-6 In this embodiment of the invention, a steel pipe bundle assembly device for a steel structure building includes a base 1, a fixing component 2, a clamping mechanism 3, a welding mechanism 4, and a conveying mechanism 5. The fixing component 2 is fixedly mounted on the base 1. The clamping mechanisms 3 are symmetrically arranged on both sides of the fixing component 2. The fixing component 2 includes four symmetrically arranged support columns 21. Two crossbeams 22 and a locking rod 23 are fixedly mounted on two support columns 21 located on the same side. A guide clamping mechanism 6 is arranged between two opposite support columns 21. Two sliding seats 24 are slidably mounted on the locking rod 23. A welding seat is raised and lowered on the sliding seat 24 by a hydraulic telescopic rod. A welding mechanism 4 is slidably mounted on the welding seat. The conveying mechanism 5 is used to convey steel pipes, and multiple conveying grooves are opened on the conveying surface of the conveying mechanism 5.

[0033] The guide clamping mechanism 6 includes a guide clamping rod 61, an L-shaped limiting rod 62, and a locking block 63. Two sliders 211 are slidably mounted on the support column 21 via a coaxial reverse screw. Support rods 212 are hinged to the sliders 211, and the other ends of the two support rods 212 are hinged to the guide clamping rod 61. An L-shaped limiting rod 62 is slidably mounted in the guide clamping rod 61 via a screw, and the two L-shaped limiting rods 62 are slidably locked together. Fixing blocks 611 are fixedly mounted on both sides of the guide clamping rod 61, and a locking block 63 with a downward-sloping inclined surface is slidably mounted in each fixing block 611 via a spring.

[0034] The clamp mechanism 3 includes a fixed bracket 31, a movable cross bar 32 and a clamp assembly 33, wherein the movable cross bar 32 is slidably provided on the fixed bracket 31 by means of a second screw, the clamp assembly 33 is slidably provided on the movable cross bar 32, and two clamping rods 2 34 are fixedly provided on the fixed bracket 31, and the two clamping rods 2 34 are slidably connected to the two clamping rods 1 23 respectively.

[0035] In implementation, the base 1 is fixed to the ground. Then, the positions of the two clamping mechanisms 3 are adjusted and fixed according to the length of the steel pipe. During this process, the second clamping rod 34 slides along the first clamping rod 23. Then, the steel pipe is transported to the bottom of the fixing component 2 using the conveying mechanism 5. Then, the distance between the two guide clamping rods 61 is adjusted according to the width of the welded surface of the steel pipe. The steel pipe is clamped by the two clamping mechanisms 3 and then transported between the two guide clamping rods 61. After contacting the clamping block 63, the clamping block 63 is pushed to slide. After disengaging from the clamping block 63, the clamping block 63 is reset under the action of the spring, thus placing the steel pipe smoothly between the two guide clamping rods 61. Then, the clamping mechanism 3 is used to place the next steel pipe between the two guide clamping rods 61 in the same way. Before placement, the two steel pipes are aligned using the two clamping mechanisms 3. Then, the slider 211 is driven to slide, causing the two guide clamping rods 61 to clamp the two steel pipes. Simultaneously, the two L-shaped limiting rods 62 are driven to slide down and press the two steel pipes together, thus completely fixing the two steel pipes. Then, the sliding block 24 is used to move the welding mechanism 4 to weld the two steel pipes. After welding, the guide clamping rods 61 and L-shaped limiting rods 62 are released, and the two clamping mechanisms 3 are used to place new steel pipes for welding until the entire steel pipe bundle is welded and assembled. The welded and assembled steel pipe bundle can be removed from the side of the fixing component 2, thereby realizing the automatic welding and assembly of the steel pipe bundle, effectively improving the assembly quality and efficiency of the steel pipe bundle, further improving the safety of the entire building and shortening the construction cycle.

[0036] In this embodiment, Figure 4 and Figure 5 The clamp assembly 33 includes a moving block 331, a turntable 1 332 and a turntable 2 333, wherein the moving block 331 is slidably arranged on the moving cross bar 32, a hydraulic telescopic rod 2 is fixedly arranged on the moving block 331, a turntable 1 332 is fixedly arranged on the output end of the hydraulic telescopic rod 2, a turntable 2 333 is rotatably arranged on the turntable 1 332, and a cross clamping mechanism 35 is fixedly arranged on the turntable 2 333;

[0037] The cross-shaped locking mechanism 35 includes a cross-shaped fixing frame 351, a drive rod 352, and a support rod 353. The cross-shaped fixing frame 351 is fixedly mounted on the turntable 333. The cross-shaped fixing frame 351 has four locking slots 354 in a cross shape. The drive rod 352 is rotatably mounted in the locking slots 354. The output end of the drive rod 352 is hinged to the support rod 353. A hydraulic telescopic rod 355 is fixedly mounted in the locking slots 354. A T-shaped connecting rod is fixedly mounted at the output end of the hydraulic telescopic rod 355. The drive rod 352 has a T-shaped groove. The connecting rod is inserted into the T-shaped groove and slides along the T-shaped groove.

[0038] In implementation, the sliding of the movable crossbar 32 drives the cross clamping mechanism 35 to move vertically, and the sliding of the movable block 331 drives the cross clamping mechanism 35 to move laterally. The horizontal position of the cross clamping mechanism 35 is adjusted by the extension and retraction of the hydraulic telescopic rod 2, thereby effectively clamping and transporting the steel pipe between the two guide clamping rods 61. After the cross clamping mechanism 35 clamps the steel pipe, the rotation of the turntable 2 333 can adjust the placement position of the steel pipe, so that the welding surfaces of the two steel pipes are aligned. The extension and retraction of the hydraulic telescopic rod 2 is used to align the two steel pipes, further improving the welding quality. In addition, when clamping the steel pipe, the cross clamping assembly 35 mainly uses four support rods 353 to clamp the steel pipe, and the support range of the four support rods 353 is controlled by four independently set hydraulic telescopic rods 355, so that the support range of the support rods 353 is adjustable, that is, it can effectively clamp various types of steel pipes, further expanding the overall applicability of the device.

[0039] In this embodiment, Figure 5 The support rod 353 has a T-shaped connecting rod 356 slidably disposed on the side near the turntable 333. The turntable 333 has four T-shaped grooves 334 circumferentially formed. The connecting rod 356 is inserted into the T-shaped grooves 334 and slides along the T-shaped grooves 334. The end of the connecting rod 356 that is inserted into the T-shaped grooves 334 is a rectangular rod.

[0040] Specifically, one end of the connecting rod 356 that is inserted into the T-slot 334 is set as a rectangular rod, so that the connecting rod 356 can always remain perpendicular to the turntable 333 during the sliding process, thereby ensuring that the support rod 353 can also remain perpendicular to the turntable 333 during the sliding process. That is, the four support rods 353 always maintain a cross shape during the opening and closing process, thus ensuring that the support rods 353 can firmly clamp the steel pipe.

[0041] In this embodiment, Figure 4 and Figure 6 The first locking rod 23 is provided with a sliding groove 231, and two racks are symmetrically slidably arranged in the sliding groove 231. The second locking rod 34 is provided with a sliding groove 341, and a rack is slidably arranged in the sliding groove 341.

[0042] A rotating shaft 241 is rotatably mounted on the slide block 24. Two gears are fixedly mounted on the rotating shaft 241. The rotating shaft 241 can engage with the first slide groove 231 and the second slide groove 341 and slide along the first slide groove 231 and the second slide groove 341. The two gears can mesh with the first rack and the second rack respectively, and the sliding distance between the first rack and the second rack is the distance between two teeth. The rotation of the rotating shaft 241 is driven by a drive motor.

[0043] In practice, the slide block 24 can slide along the first locking rod 23 and the second locking rod 34 respectively, and the sliding force is achieved through the meshing transmission of the two gears with the first rack and the second rack. When the distance between the first locking rod 23 and the second locking rod 34 changes, that is, when the teeth of the first rack and the second rack are misaligned, the sliding of the first rack and the second rack ensures that no matter how the first locking rod 23 and the second locking rod 34 slide, the two gears can mesh with the first rack and the second rack.

[0044] In this embodiment, Figure 5 The turntable 1 332 is provided with an arc-shaped groove 335, and an annular hydraulic cavity is provided in the arc-shaped groove 335;

[0045] An arc-shaped rotating block 336 is fixedly installed on the turntable 333, and an annular hydraulic rod is fixedly installed on the arc-shaped rotating block 336. The arc-shaped rotating block 336 rotates along the arc-shaped rotating groove 335, and the annular hydraulic rod slides along the annular hydraulic cavity.

[0046] A method for assembling steel pipe bundles in a steel structure building includes the following steps:

[0047] S1. Fix the fixing assembly 2 on the ground, adjust the positions of the two clamp mechanisms 3 according to the length of the steel pipe to be welded, and fix the two clamp mechanisms 3;

[0048] In addition, when adjusting the position of the two clamping mechanisms 3, the sliding of the first clamping rod 23 and the second clamping rod 34 can keep the two clamping mechanisms 3 and the fixing component 2 in the same horizontal direction, thereby ensuring that the two clamping mechanisms 3 can effectively place the steel pipe into the fixing component 2.

[0049] S2. The steel pipe to be welded is transported to the bottom of the fixing component 2 using the conveying mechanism 5, and the distance between the two guide clamping rods 61 is adjusted according to the width of the steel pipe. The surface of the conveying mechanism 5 is provided with multiple conveying grooves, which can restrict the steel pipe so that the steel pipe will not deviate significantly during the conveying process. This allows the cross clamping mechanism 35 in the clamping mechanism 3 to effectively extend into the steel pipe and clamp it.

[0050] S3. By sliding the moving crossbar 32 and the moving block 331, the cross locking mechanism 35 is aligned with the end of the steel pipe. The turntable 1 332 and the turntable 2 333 are driven to slide by the hydraulic telescopic rod 2, so that the cross locking mechanism 35 extends into the steel pipe.

[0051] S4. Drive the drive rod 352 to deflect by the hydraulic telescopic rod 355, so that the four support rods 353 support the steel pipe and fix the steel pipe, and rotate the turntable 333 so that the welding surface of the steel pipe is in a horizontal position, that is, the welding surface of the steel pipe is aligned according to the welding requirements of the steel pipe.

[0052] S5, using the sliding movement of the movable cross bar 32 and the movable block 331 to transport the steel pipe to between the two guide clamping rods 61, and placing the steel pipe on the two guide clamping rods 61 through the clamping block 63;

[0053] In this process, the L-shaped limiting rod 62 is first loosened so that the steel pipe is not restricted by the L-shaped limiting rod 62 during placement. That is, the L-shaped limiting rod 62 only presses the steel pipe before welding.

[0054] S6. Repeat steps S3 to S5, place the next steel pipe on the two guide clamping rods 61, and align the two steel pipes by sliding the hydraulic telescopic rod 2 during the placement process. Then drive the two guide clamping rods 61 to slide to clamp the two steel pipes and drive the L-shaped limiting rod 62 to slide down to press the two steel pipes together. Then use the welding mechanism 4 to weld the two steel pipes.

[0055] S7. Repeat steps S3 to S6 until the welding of the steel pipe bundle is completed. Loosen the guide clamping rod 61 and the L-shaped limiting rod 62, and remove the welded steel pipe bundle from the side of the fixing component 2 for subsequent processing.

[0056] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
