Description

Technical Field

[0001] This invention relates to the field of steel pipe straightening technology, specifically to a building steel pipe straightening device and its working method. Background Technology

[0002] On construction sites, the exterior of buildings is usually assembled with steel pipes to form protective frames. Some of these steel pipes may be damaged or deformed during use and need to be reshaped.

[0003] A search revealed a steel pipe straightening device published under publication number CN210847736U. This device uses a circular groove on the straightening base to fix the steel pipe, which solves the problem that a large amount of rust on the surface of the steel pipe before straightening would seriously affect the welding quality. However, it can only straighten the verticality of the steel pipe, and cannot restore the bent and recessed parts, resulting in insufficient load-bearing capacity of the steel pipe after straightening, making it prone to bending. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a structural steel pipe straightening device, primarily designed to solve the problem that only the verticality of steel pipes can be straightened.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: A steel pipe straightening device for construction includes a base plate. A second straightening frame is fixedly connected to the upper surface of the base plate. Multiple sliding grooves are formed on the upper surface of the base plate, and the same first straightening frame is slidably connected within each of the multiple sliding grooves. A cylinder is fixedly connected to one side of the base plate, with one end of the cylinder's pneumatic rod extending into the sliding groove and fixed to the first straightening frame. A placement box is fixedly connected to one side of the base plate, containing multiple threaded rods. Each threaded rod has a connector and a first threaded hole at both ends. A placement hole is formed on the upper surface of the placement box, containing a straightening head. A second threaded hole is formed on the upper surface of the straightening head. A fixed column is fixedly connected to one side of the base plate, with a rotating frame rotatably connected to one end of the fixed column. A clearance groove is formed on one side of the rotating frame, with round holes on both sides of the clearance groove. A first half-rotor and a second half-rotor are located within the clearance groove, connected by a connecting mechanism. A limiting component for limiting the rotation frame is provided on one side of the fixed column. Auxiliary fixing mechanisms are provided on both sides of the base plate.

[0006] Furthermore, the connecting mechanism includes a second card holder, which is fixed to the second half of the turntable. A second slot is provided on one side of the first half of the turntable, and the second card holder engages with the second slot. A first slot is provided on one side of the first half of the turntable, and a guide groove is provided on one side of the second half of the turntable. A first card holder is slidably connected in the guide groove and engages with the first slot. A spring is fixedly connected to the bottom of the first card holder and is fixed to the guide groove.

[0007] Based on the aforementioned scheme, a connecting rod is fixedly connected to the upper surface of the first card holder, and a sliding hole is provided on one side of the first half-turntable, with the connecting rod slidably connected to the sliding hole.

[0008] As a further embodiment of the present invention, the limiting component includes an arc-shaped groove, and a limiting block is fixedly connected to one side of the rotating frame, and the limiting block is slidably connected to the arc-shaped groove.

[0009] Furthermore, the auxiliary fixing mechanism includes a slide, and the base plate has movable grooves on both sides. The slide is slidably connected to the movable grooves. A retaining band is fixedly connected to one side of the slide, and two fixing blocks are fixedly connected to the other side of the slide. A limit frame is rotatably connected between the two fixing blocks, and the limit frame locks the retaining band.

[0010] Based on the aforementioned scheme, a sponge pad is fixedly connected inside the placement box, and a cover plate is rotatably connected to the upper surface of the placement box.

[0011] As a further embodiment of the present invention, the bottom of the base plate is fixedly connected with a plurality of feet.

[0012] Furthermore, anti-slip pads are fixedly connected to the bottom of each of the aforementioned feet.

[0013] This invention also proposes a working method for a structural steel pipe straightening device, comprising the following steps: S1: Fix the steel pipe, place the steel pipe between the first and second correction frames on the upper surface of the base plate, then rotate the limiting frame so that the limiting frame no longer jams the clamping tape, move the slide along the moving grooves on both sides of the base plate, move the slide directly under both ends of the steel pipe, use the clamping tape to tie the steel pipe tightly, and then fix the clamping tape through the limiting frame; S2: Initial correction. Start the cylinder on one side of the base plate. The cylinder extends and pushes the first correction frame to move along the slide. The first correction frame corrects the steel pipe. During the correction of the steel pipe, the steel pipe will drive the slide to move. After the steel pipe is straightened, rotate the rotating frame. After the rotating frame is rotated to a certain angle and aligned with the steel pipe, take out the first half of the rotating frame and the second half of the rotating frame from the clearance groove. S3: Disassemble the turntable, take out the threaded rod and the calibration head from the box on one side of the base plate, pass the threaded rod through the round holes on both sides of the rotating frame, then connect the threaded rod to the second threaded hole on the calibration head through the connector, then press the connecting rod, the connecting rod will push the first card holder to move along the guide groove and squeeze the spring, so that the first card holder is disengaged from the first card slot, and disassemble the first half turntable and the second half turntable; S4: Connect the turntable, clamp the first half of the turntable on the outside of the threaded rod, then rotate the threaded rod to rotate the first half of the turntable into the clearance groove of the rotating frame, then engage the second bracket on the second half of the turntable with the second slot on the first half of the turntable, and engage the first bracket on the second half of the turntable with the first slot on the first half of the turntable, thereby connecting the first half of the turntable and the second half of the turntable; S5: Full calibration. The worker holds the first and second half of the turntable with one hand and rotates the threaded rod with the other hand, which will cause the calibration head to enter the inside of the steel pipe, supporting the recessed part of the steel pipe and performing a complete calibration of the steel pipe.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a structural steel pipe straightening device and its working method, which has the following beneficial effects: 1. By using the threaded rod and the straightening head together, after the steel pipe is straightened by the first straightening frame and the second straightening frame, the connector on the threaded rod can be connected to the second threaded hole on the straightening head. Then, the straightening head is inserted into the steel pipe, thereby supporting the recessed part of the steel pipe, completely straightening the steel pipe, enhancing the bearing capacity of the steel pipe, and improving the effectiveness of the straightening device.

[0015] 2. The connecting mechanism allows the first and second half of the turntable to be connected, facilitating their disassembly and reassembly. This makes it easier for workers to insert the threaded rod into the round hole, improving the ease of use of the calibration device.

[0016] 3. By setting up an auxiliary fixing mechanism, the steel pipe can be fixed in place before the first and second correction frames are used to correct it. This makes the steel pipe more stable and improves the stability of the correction device.

[0017] 4. With the base set, after the alignment device is placed on the ground, the anti-slip pads on the base will come into contact with the ground. At this time, the anti-slip pads can increase the friction between the base and the ground, thereby making the alignment device more stable and improving the stability of the alignment device.

The cylinder 2 is activated, and the cylinder 2 extends to push the first straightening frame 3 to move along the slide groove 5, so that the first straightening frame 3 straightens the steel pipe. After the steel pipe is straightened, the rotating frame 16 is rotated. After the rotating frame 16 is rotated to a certain angle and aligned with the steel pipe, the first half-turntable 20 and the second half-turntable 30 are taken out from the clearance groove 21.

The worker holds the first half of the turntable 20 and the second half of the turntable 30 with one hand, and rotates the threaded rod 12 with the other hand. This will cause the calibration head 14 to enter the inside of the steel pipe, supporting the recessed part of the steel pipe and completely calibrating the steel pipe. This will enhance the load-bearing capacity of the steel pipe and improve the effectiveness of the calibration device.
