Description

Technical Field

[0001] The present invention relates to the technical field of pipe straightening, and in particular to a pipe straightening device and method based on a steel structure building. Background Art

[0002] Construction pipes are widely used on construction sites, especially steel pipes. During use or transportation, pipes used in steel structure construction often bend or dent, or become deformed. These deformations will affect the normal use of steel structure construction pipes. Therefore, construction sites usually use special straightening devices to straighten construction pipes.

[0003] An existing patent (publication number: CN108817139B) discloses a steel pipe straightening machine comprising an inverted Pi-shaped support, with first bearings embedded in both side plates of the support opening, the two first bearings being coaxially arranged. The machine also comprises a straightening component comprising a cylindrical hollow cylindrical bin, with cylindrical bearing seats coaxially disposed at both ends of the bin. A straightening die tube allows the steel pipe to pass through and gradually straightens the pipe. The steel pipe straightening machine has good straightening effects and causes minimal damage to the pipe. Since the pipe is hollow, when it is bent, it will not only bend as a whole, but also cause local depression. This condition is difficult to recover even if the pipe is squeezed by an external straightening ring. Therefore, the outer wall of the pipe will still be depressed inward, affecting normal use. Summary of the Invention

[0011] The working method of the pipe straightening method based on steel structure building includes the following steps: Step 1, one end of the pipe to be straightened is passed through the straightening assembly 1 and the straightening assembly 2 in sequence, and is positioned between the two sets of clamping blocks, and then the electric push rod 2 is driven to push the clamping blocks toward the pipe to clamp the pipe; Step 2: After clamping the pipe, turn on motor 1. The output end of motor 1 drives the rotating rod to rotate in the forward direction. Gear 1 drives the threaded rod to rotate under the action of gear 2. The movable block 1 and the movable block 2 pull the pipe toward the support plate under the joint action of the threaded rod and the fixed rod. The other end of the pipe is straightened by straightening assembly 1 and straightening assembly 2. Step 3. When the pipe passes through the straightening plate on the right, the straightening plate is elastically squeezed by the spring 1 and the elastic sheet, and the straightening plate is slightly straightened. After being slightly straightened by the straightening plate on the right, the pipe passes through the straightening plate on the left again. The movable range of the straightening plate on the left is smaller than that of the straightening plate on the right. Therefore, the straightening plate on the left further straightens the pipe under the action of the corresponding spring and the elastic sheet.

The inner diameter of the straightening ring is the same as the outer diameter of the pipe. Step 4. During the rotation of the rotating rod, the infrared ranging sensor rotates with it. The infrared ranging sensor is located on the outside of the rotating block and detects the distance between the protrusion on the inner wall of the pipe and the distance between it. When the protrusion on the inner wall of the pipe moves to correspond to the hammering block, motor 1 stops running and starts motor 2. The output end of motor 2 drives the rotating block to rotate. The infrared ranging sensor detects the protrusion position on the inner wall of the pipe again. When it is detected again that the protrusion on the inner wall of the pipe corresponds to the hammering block, motor 2 stops running and starts the electric push rod to repeatedly push the hammering block to repeatedly hammer the protrusion until the convex surface of the protrusion located below the hammering block is completely hammered flat. Then motor 2 continues to drive the rotating block to rotate. When the remaining convex surfaces of the protrusion are detected again, they are hammered according to the above steps. When the output end of motor 2 rotates one circle and completes the hammering of the protrusion, motor 2 stops running and motor 1 continues running to move the pipe toward the support plate. The hammering assembly hammers the next group of protrusions again according to the above steps.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In the present invention, by arranging the straightening assembly 1 and the straightening assembly 2 to cooperate with each other, the straightening plate can be used to sequentially perform elastic straightening of the pipe with different amplitudes so that the pipe is bent slightly, and then the straightening ring can be used to perform rigid straightening. Compared with large-amplitude rigid extrusion, it can avoid the occurrence of excessive correction and the occurrence of multiple secondary deformation damages. In the present invention, the beating assembly cooperates with the rotating rod and the motor. In the process of using the motor to drive the rotating rod and the threaded rod to rotate so that the clamping block drives the pipe to move automatically, the infrared ranging sensor rotates with the rotating rod. The closest distance between the infrared ranging sensor and the inner wall of the straightened pipe is 1 mm. The infrared ranging sensor is used to detect the distance between the protrusion and the sensor, so as to determine whether the protrusion exists and the distance between the protrusion and the beating block along the central axis of the pipe. Then, when the protrusion moves to the area corresponding to the beating block, the driving motor 2 drives the beating block to rotate so that the beating block is located on the opposite side of the protrusion. Then, the electric push rod 1 is driven to push the beating block to repeatedly beat the protrusion until the minimum distance detected is greater than the distance between the infrared ranging sensor and the beating block. Therefore, while realizing automatic elastic straightening, the protrusion on the inner wall of the pipe can be targetedly beaten to prevent the outer wall of the straightened pipe from being concave inward.

One end of the pipe to be straightened passes through the straightening component 1 4 and the straightening component 2 5 in sequence, and is located inside the fixing component 7. The fixing component 7 is used to fix it. The motor 1 201 drives the rotating rod 202 to rotate. Since the gear 205 is engaged with the gear 1 204, the threaded rod 203 can drive the fixing component 7 to move the pipe. A control panel is provided inside the straightening frame 3, and the control panel controls the operation of the corresponding live components.

[0017] The fixing assembly 7 includes a movable block 1 701, a movable block 2 702, an electric push rod 2 703, a clamping block 704 and a rubber block 705; the outer surface of the threaded rod 203 is threadedly connected to the movable block 1 701, and the outer surface of the fixed rod 206 is movably connected to the movable block 2 702 at a position corresponding to the movable block 1 701, and the outer surfaces of the movable blocks 1 701 and 702 are each provided with an electric push rod 2 703 on one side close to each other, and one end of the electric push rod 2 703 is fixed to the corresponding movable block 1 701 and movable block 2 702. The pipe is fixedly connected, and the other end is fixedly connected with a clamping block 704.

The outer surfaces of the two groups of clamping blocks 704 are fixedly connected with connecting blocks 706 near both ends. A movable bolt 707 is arranged between the two corresponding groups of connecting blocks 706. The movable bolt 707 is movably connected to the corresponding connecting block 706. Between the two groups of clamping blocks 704 at one end of the pipe, the electric push rod 2 703 is driven to push the clamping block 704 toward the pipe to clamp the pipe.

[0018] Example 2: like Figure 2-6 As shown, the difference between this embodiment and embodiment 1 is that the straightening component 1 4 includes a movable groove 1 401, a movable groove 2 402, a spring 403 and a movable column 404; a movable groove 1 401 and a movable groove 2 402 are provided at one end of the inner surface of the straightening frame 3 away from the threaded rod 203, and the movable groove 1 401 and the movable groove 2 402 are both in four groups, and the four groups of movable grooves 1 401 and movable groove 2 402 are respectively distributed around the inner surface of the straightening frame 3, and the movable groove 1 401 and the movable groove 2 402 correspond one to one, the movable groove 1 401 is located on the right side of the movable groove 2 402, and the depth value of the movable groove 1 401 is greater than the depth value of the movable groove 2 402, and a spring 403 is provided inside the movable groove 1 401 and the movable groove 2 402, and one end of the spring 403 is fixedly connected to the corresponding movable groove 1 401 and movable groove 2 402, and the other end is fixedly connected to the movable column 404.

[0019] The movable range value of the movable column 404 corresponding to the movable groove 1 401 is greater than the movable range value of the movable column 404 corresponding to the movable groove 2 402. One end of the movable column 404 is fixedly connected to the spring 403, and the other end is fixedly connected to the straightening plate 405. The movable column 404 is movably connected to the corresponding movable groove 1 401 and the movable groove 2 402. The inner surface of the straightening plate 405 is arc-shaped, and the inner surface of the straightening plate 405 is embedded with a plurality of groups of steel balls 406 in a rolling connection to reduce the friction loss generated during the movement of the pipe. An elastic sheet 407 is fixedly connected between the adjacent two side groups of straightening plates 405. The two ends of the elastic sheet 407 are respectively connected to the two groups of straightening plates 405. The inner surface of the straightening frame 3 is fixedly connected, and the elastic sheet 407 protrudes toward the inside of the straightening frame 3. When the pipe passes through the straightening plate 405 on the right, the straightening plate 405 is elastically squeezed by the spring 403 and the elastic sheet 407, and the straightening plate 405 is slightly straightened. After being slightly straightened by the straightening plate 405 on the right, the pipe passes through the straightening plate 405 on the left again. The movable range of the straightening plate 405 on the left is smaller than the movable range of the straightening plate 405 on the right. Therefore, the straightening plate 405 on the left further straightens the pipe under the action of the corresponding spring 403 and the elastic sheet 407.

[0020] Example 3: like Figure 4 、 Figure 5 and Figure 7 As shown, the difference between this embodiment and embodiment 1 and embodiment 2 is that the straightening component 2 5 includes a fixed column 501, a fixed ring 502 and a straightening ring 503; the upper and lower ends of the inner surface of the straightening frame 3 are fixedly connected with the fixed columns 501, the fixed ring 502 is fixedly connected between the two groups of fixed columns 501, and the inner surface of the fixed ring 502 is fixedly connected with the straightening ring 503, the inner surface of the straightening ring 503 is arc-shaped, the inner diameter of the straightening ring 503 is the same as the outer diameter of the pipe, the pipe passes through the straightening ring 503, and is straightened for the last time under the extrusion of the straightening ring 503.

[0021] The hammering assembly 6 includes a mounting groove 601, a second motor 602, a rotating block 603, a support block 604 and an electric push rod 1 605; the end of the rotating rod 202 away from the support plate 2 passes through the interior of the straightening frame 3, and the end of the rotating rod 202 located inside the straightening frame 3 is provided with a mounting groove 601, the interior of the mounting groove 601 is provided with a second motor 602, and the output end of the second motor 602 passes through the outside of the mounting groove 601 and is fixedly connected to the rotating block 603, the output end of the second motor 602 is rotatably connected to the rotating rod 202, and the outer surface of one side of the rotating block 603 is fixedly connected to the support block 604 near the edge.

[0022] An electric push rod 605 is provided on the outer surface of one side of the support block 604, and one end of the electric push rod 605 is fixedly connected to the support block 604, and the other end is fixedly connected to a hammering block 606. The outer surface of the hammering block 606 is arc-shaped, and the hammering block 606 corresponds to the straightening ring 503. The straightening ring 503 can support the hammering of the hammering block 606. An infrared distance sensor 607 is provided at the position corresponding to the hammering block 606 on the outer surface of the rotating block 603, and the infrared distance sensor 607 is located on the left side of the hammering block 606. The infrared distance sensor 607 is located on the outside of the rotating block 603. The infrared distance sensor 607 rotates with the rotating rod 202 and detects the distance between the protrusion on the inner wall of the pipe and the infrared distance sensor 607. The distance between the protrusion on the inner wall of the pipe and the infrared distance sensor 607 is less than the distance between the center of the straightening ring 503 and the center of the straightening plate 405 on the left. At the same time, the displacement of the pipe along the axial direction of the fixed rod 206 is detected by displacement sensing. When the infrared distance sensor 607 detects the distance between itself and the protrusion on the inner wall of the pipe for the first time, it starts to calculate the displacement of the pipe along the fixed rod 206. When the displacement of the pipe along the direction of the fixed rod 206 is equal to the spacing between the protrusion of the inner wall of the pipe and the beating block 606 along the axial direction of the pipe, the beating block 606 corresponds to the protrusion of the inner wall of the pipe. At this time, the motor 1 201 is stopped and the motor 2 602 is started. The output end of the motor 2 602 drives the rotating block 603 to rotate. The infrared ranging sensor 607 detects the protrusion position of the inner wall of the pipe again. In order to ensure that the beating block 606 moves to the opposite side of the corresponding protrusion, when it is detected again that the protrusion of the inner wall of the pipe corresponds to the beating block 606, the motor 2 602 is stopped and the electric push rod is started to repeatedly push the beating block 606 to repeatedly beat the protrusion until the convex surface of the protrusion below the beating block 606 is completely beaten flat. The minimum distance detected by the distance sensor 607 is greater than the distance between the infrared distance sensor 607 and the hammering block 606 to determine whether the position protrusion corresponding to the hammering block 606 disappears, and then the motor 2 602 continues to drive the rotating block 603 to rotate. When the remaining convex surfaces of the protrusion are detected again, it is hammered according to the above steps. When the output end of the motor 2 602 rotates one circle and completes the hammering of the protrusion, the motor 2 602 stops running, and the motor 1 201 continues to run to move the pipe toward the support plate 2. The hammering component 6 hammers the next group of protrusions again according to the above steps. Compared with the prior art in which the extrusion block is penetrated inside the pipe to extrude the protrusion, the protrusion is hammered in a targeted manner, which is more efficient and reduces friction loss.

[0023] Example 4: like Figure 1-7As shown, the working method of the pipe straightening method based on steel structure construction includes the following steps: Step 1, one end of the pipe to be straightened is passed through the straightening assembly 1 4 and the straightening assembly 2 5 in sequence, and is positioned between the two sets of clamping blocks 704, and then the electric push rod 2 703 is driven to push the clamping blocks 704 toward the pipe to clamp the pipe; Step 2: After clamping the pipe, turn on the motor 1 201. The output end of the motor 1 201 drives the rotating rod 202 to rotate in the forward direction. The gear 1 204 drives the threaded rod 203 to rotate under the action of the gear 2 205. The movable block 1 701 and the movable block 2 702 pull the pipe toward the support plate 2 under the joint action of the threaded rod 203 and the fixed rod 206. The other end of the pipe is straightened by the straightening component 1 4 and the straightening component 2 5. Step 3: When the pipe passes through the straightening plate 405 on the right, the straightening plate 405 is elastically squeezed by the spring 403 and the elastic sheet 407, and the straightening plate 405 is slightly straightened. After being slightly straightened by the straightening plate 405 on the right, the pipe passes through the straightening plate 405 on the left again. The movable range of the straightening plate 405 on the left is smaller than that of the straightening plate 405 on the right. Therefore, the straightening plate 405 on the left further straightens the pipe under the action of the corresponding spring 403 and the elastic sheet 407. The pipe straightened by the straightening plate 405 passes through the inside of the fixing ring 502 and is straightened for the last time under the squeeze of the straightening ring 503. The inner diameter of the straightening ring 503 is the same as the outer diameter of the pipe. Step 4: During the rotation of the rotating rod 202, the infrared distance sensor 607 rotates with it. The infrared distance sensor 607 is located on the outside of the rotating block 603 and detects the distance between the protrusion on the inner wall of the pipe and the infrared distance sensor 607. The distance between the protrusion on the inner wall of the pipe and the infrared distance sensor 607 is less than the distance between the center of the straightening ring 503 and the center of the straightening plate 405 on the left. The displacement of the pipe along the axial direction of the fixed rod 206 is detected by displacement sensing. When the infrared distance sensor 607 detects the distance between itself and the protrusion on the inner wall of the pipe for the first time, the displacement of the pipe along the direction of the fixed rod 206 is calculated. When the displacement of the pipe along the direction of the fixed rod 206 is equal to the distance between the protrusion on the inner wall of the pipe and the hammering block 606 along the axial direction of the pipe, the hammering block 606 corresponds to the protrusion on the inner wall of the pipe. At the same time, the axial displacement of the pipe along the fixed rod 206 is collected. When it is calculated that the protrusion on the inner wall of the pipe moves to correspond to the hammering block 606, the motor 1 201 stops running and the motor 2 602 is started. The output end of the motor 2 602 drives the rotating block 603 to rotate, and the infrared ranging sensor 607 detects the position of the protrusion on the inner wall of the pipe again. When it is detected again that the protrusion on the inner wall of the pipe corresponds to the hammering block 606, the motor 2 602 stops running and the electric push rod is started to repeatedly push the hammering block 606 to repeatedly hammer the protrusion until the convex surface of the protrusion located below the hammering block 606 is completely hammered flat. According to the minimum distance detected by the infrared ranging sensor 607, which is greater than the distance between the infrared ranging sensor 607 and the hammering block 606, it is judged whether the convex surface corresponding to the hammering block 606 is hammered flat, and then the motor 2 602 continues to drive the rotating block 603 to rotate. When the remaining convex surfaces of the protrusion are detected again, they are hammered according to the above steps. When the output end of the motor 2 602 rotates one circle and completes the hammering of the protrusion, the motor 2 602 stops running, and the motor 1 201 continues to run to move the pipe toward the support plate 2. The hammering component 6 hammers the next group of protrusions again according to the above steps.

[0024] The above are only preferred specific embodiments 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.

Then, drive the electric push rod 2 (703) to push the clamping block (704) toward the pipe to clamp the pipe; Step 2: After clamping the pipe, turn on the motor 1 (201), the output end of the motor 1 (201) drives the rotating rod (202) to rotate in the forward direction, the gear 1 (204) drives the threaded rod (203) to rotate under the action of the gear 2 (205), the movable block 1 (701) and the movable block 2 (702) pull the pipe toward the support plate (2) under the joint action of the threaded rod (203) and the fixed rod (206), and the other end of the pipe is straightened through the straightening component 1 (4) and the straightening component 2 (5); Step 3: When the pipe passes through the straightening plate (405) on the right side, the straightening plate (405) is elastically squeezed by the spring (403) and the elastic sheet (407), and the straightening plate (405) is slightly straightened. After being slightly straightened by the straightening plate (405) on the right side, the pipe passes through the straightening plate (405) on the left side again. The movable range of the straightening plate (405) on the left side is smaller than the movable range of the straightening plate (405) on the right side. Therefore, the straightening plate (405) on the left side further straightens the pipe under the action of the corresponding spring (403) and the elastic sheet (407).

When the protrusion on the inner wall of the pipe moves to correspond to the hammering block (606), the motor 1 (201) stops running and the motor 2 (602) is started. The output end of the motor 2 (602) drives the rotating block (603) to rotate. The infrared distance sensor (607) detects the position of the protrusion on the inner wall of the pipe again. When it is detected again that the protrusion on the inner wall of the pipe corresponds to the hammering block, the motor 2 ( 602) stops running, starts the electric push rod to repeatedly push the hammering block (606) to repeatedly hammer the protrusion until the convex surface of the protrusion located below the hammering block (606) completely disappears, and then the motor 2 (602) continues to drive the rotating block (603) to rotate. When the remaining convex surfaces of the protrusion are detected again, they are hammered according to the above steps. When the output end of the motor 2 (602) rotates one circle and completes the hammering of the protrusion, the motor 2 (602) stops running, and the motor 1 (201) continues running to move the pipe toward the support plate (2). The hammering assembly (6) hammers the next group of protrusions again according to the above steps.
