Description

Technical Field

[0001] This invention relates to the field of spatial cross steel beam construction technology, and in particular to a construction device and construction method for spatial cross steel beams. Background Technology

[0002] In the field of steel structure construction, the installation of spatially intersecting steel beams (such as large-span stadiums, high-rise building corridors, and irregular structures) has always been a technical challenge.

[0003] Traditional construction methods suffer from the following problems: insufficient positioning accuracy, relying on cranes and manual pry bars for adjustment, depending on experience, often resulting in errors greater than 5mm; difficulty in adjusting the angle of skewed steel beams, easily leading to misalignment of bolt holes at nodes; outdated temporary fixing methods, such as welding temporary supports or using mechanical clamps, which may damage the anti-corrosion layer of the base material, and high-altitude welding poses a fire risk; traditional electromagnetic chucks can only adsorb in one direction and cannot adapt to the multi-angle stress of cross beams; and low efficiency in quality inspection, with weld and bolt inspection relying on manual tapping and ultrasonic sampling, resulting in many blind spots in high-altitude operations, inability to digitize inspection data in real time, and difficulty in acceptance and traceability. Summary of the Invention

[0008] Preferably, a second motor is installed on the support plate, and the output end of the second motor is installed with rotating teeth in the circular groove of the first electromagnetic adsorption seat. The inner wall of the circular groove is provided with inner ring teeth, and the inner ring teeth mesh with the rotating teeth.

[0009] Preferably, the base has symmetrically arranged sliding grooves inside, and a first threaded rod is installed in the sliding groove with a bearing. The first threaded rod is threadedly connected to the sliding plate in the sliding groove, and the sliding plate is connected to the movable rod. A synchronous pulley is installed at the end of the first threaded rod, and the two synchronous pulleys are synchronously connected by a synchronous belt drive. A third motor on the outside of the base is connected to one of the synchronous pulleys.

[0010] Preferably, a fourth motor is mounted on the movable plate, and the output end of the fourth motor is connected to one of the transmission teeth.

[0011] Preferably, a semi-circular ring rail is provided on the semi-circular toothed ring, the slide is slidably connected to the semi-circular ring rail, a fifth motor is installed on the slide, and a drive tooth that meshes with the semi-circular toothed ring is installed at the output end of the fifth motor.

[0013] Preferably, a seventh motor is installed on the support frame, and a second threaded rod that is threadedly connected to the telescopic arm is installed at the output end of the seventh motor.

[0016] A ninth motor is installed inside the ring seat, and the output end of the ninth motor is connected to one of the rollers.

[0017] A construction method for a construction device for spatially intersecting steel beams, the specific operation steps of which are as follows:

[0018] Step 1: Place the device on the top side of the end of the crossbeam. Fix it to the top side of the end of the crossbeam by adsorption using the first electromagnetic adsorption seat. Then, lift the crossbeam with a crane to the installation position. At this time, the third motor works, driving the first threaded rod to rotate through the synchronous pulley and synchronous belt, which in turn drives the threaded sliding plate to move, extending the movable rod located in the base. At the same time, the seventh motor drives the second threaded rod to rotate, which in turn drives the threaded telescopic arm to move along the linear slide rail until the second electromagnetic adsorption seat is close to the column steel structure. The first motor works, driving the transmission shaft to rotate, which drives the base to rotate on the first electromagnetic adsorption seat. The second motor works, driving the rotating teeth to rotate, which engage with the meshing inner ring teeth, driving the base to rotate, thus initially adjusting the second electromagnetic adsorption seat to ensure that the second electromagnetic adsorption seat is flush with the side of the column steel structure. At this time, the second electromagnetic adsorption seat continues to move until it contacts the side of the column steel structure, and then adsorbs the second electromagnetic adsorption seat to the column steel structure by applying electricity.

[0019] Step Two: The fourth motor drives the two transmission teeth to rotate in opposite directions at the same speed. At this time, the connecting arm drives the semi-circular toothed ring to rotate until it covers the outside of the end of the crossbeam. The fifth motor drives the drive teeth to rotate, which cooperate with the meshing semi-circular toothed ring, causing the slide to move along the semi-circular ring track. The sixth motor drives the monitoring seat to rotate, and then the connection part is viewed through the monitoring camera. At this time, the electric push rod drives the ring cover and the ring seat to move until the roller contacts the side of the column steel structure, reducing the attraction force between the second electromagnetic adsorption seat and the column steel structure. The ninth motor drives the roller to rotate, and the ring seat moves along the side of the column steel structure. The eighth motor drives the guide wheel to rotate, thereby realizing the rotation of the ring seat and the orientation of the guide wheel. Then, when the roller rotates, it realizes the multi-directional fine adjustment of the second electromagnetic adsorption seat. After the corresponding adjustment, the electric push rod retracts, increasing the attraction force between the second electromagnetic adsorption seat and the column steel structure.

[0020] Step 3: After welding and bolting the crossbeam, adjust the semi-circular toothed ring closer to the connection point. The connection point is then rotated and defect identified by the ultrasonic guided wave sensor, infrared thermal imager, and monitoring camera on the monitoring seat that moves along the semi-circular toothed ring. After the inspection is completed, the device is restored to its original state and removed from the end of the crossbeam by a crane.

[0021] The beneficial effects of this invention are: the rotating arm and support plate, together with the electromagnetic adsorption seat, achieve horizontal / vertical angle adjustment through the first motor and the second motor, and with the linear displacement of the telescopic arm, form a free space positioning capability, thereby achieving preliminary adjustment of the crossbeam during the hoisting process. Through the adjustable rollers and the adjustable adsorption force of the second electromagnetic adsorption seat, and with the cooperation of the circular moving monitoring camera, precise positioning of the crossbeam during installation is achieved.

[0022] The first electromagnetic adsorption seat is fixed at the end of the crossbeam, and the second electromagnetic adsorption seat achieves flexible contact with the column through the combined movement of rollers and ring seats. The adsorption force is adjustable, avoiding positioning deviation caused by rigid collisions.

[0023] The rotating scanning monitoring base integrates ultrasonic guided waves to detect bolt loosening, infrared thermal imaging to identify weld defects, and visual monitoring to achieve 3D modeling. It achieves 360° scanning without blind spots through the orbital movement of the semi-circular toothed ring, thus improving detection efficiency. Attached Figure Description

A synchronous pulley is installed at the end of the first threaded rod 23. The two synchronous pulleys are synchronously connected by a synchronous belt drive. The third motor 28 on the outside of the base 1 is connected to one of the synchronous pulleys.

[0035] The first motor 20 drives the transmission shaft 21 and the rotating arm 3 to rotate, so that the base 1 can rotate in the horizontal plane. This is used to roughly adjust the installation azimuth angle of the steel beam. The second motor 25 drives the rotating gear 29 to rotate. Through the engagement of the inner ring gear 27, it drives the support plate 4 to rotate around the rotating shaft 5 to adjust the angle of the steel beam end. The third motor 28 works and drives the first threaded rod 23 to rotate through the synchronous pulley and synchronous belt, so that the sliding plate 24 and the movable rod 7 can move, control the extension and retraction of the moving plate 8, and adjust the relative distance between the device and the steel structure.

[0036] Two meshing transmission gears 9 are rotatably mounted on the outer side of the movable plate 8. A fourth motor 30 is mounted on the movable plate 8, and the output end of the fourth motor 30 is connected to one of the transmission gears 9. A connecting arm 10 is mounted on the transmission gear 9, and a semi-circular toothed ring 11 is mounted at the bottom end of the connecting arm 10. A slide block 12 is slidably mounted on the semi-circular toothed ring 11, and a monitoring seat 13 is mounted on the slide block 12. An ultrasonic guided wave sensor, an infrared thermal imager, and a monitoring camera are installed inside the monitoring seat 13. A semi-circular ring rail is provided on the semi-circular toothed ring 11, and the slide block 12 is slidably connected to the semi-circular ring rail. A fifth motor 31 is mounted on the slide block 12, and a drive gear 32 that meshes with the semi-circular toothed ring 11 is mounted at the output end of the fifth motor 31. A sixth motor 33 is mounted on the slide block 12, and the output end of the sixth motor 33 is connected to the monitoring seat 13. A support frame 14 is mounted in the middle of the bottom side of the movable plate 8, and a telescopic arm is slidably mounted on the support frame 14. 15. A seventh motor 34 is installed on the support frame 14. A second threaded rod 35, which is threadedly connected to the telescopic arm 15, is installed at the output end of the seventh motor 34. A linear slide rail, which is slidably connected to the telescopic arm 15, is installed on the support frame 14. The telescopic arm 15 is connected to the second electromagnetic adsorption seat 16. A ring cover 17 is installed on the outside of the second electromagnetic adsorption seat 16. Electric push rods 36 are symmetrically installed on the second electromagnetic adsorption seat 16. The telescopic end of the electric push rod 36 is connected to the ring cover 17. A ring seat 18 is rotatably installed between the ring cover 17 and the second electromagnetic adsorption seat 16. Rollers 19 are rotatably installed at equal angles inside the ring seat 18. An eighth motor 37 is installed on the ring cover 17. A guide wheel 38, which contacts the outside of the ring seat 18, is installed at the output end of the eighth motor 37. The ring seat 18 is connected to the ring cover 17 by a bearing. A ninth motor 39 is installed inside the ring seat 18. The output end of the ninth motor 39 is connected to one of the rollers 19.

[0037] The fourth motor 30 drives the transmission gear 9 to rotate, realizing the rotation of the connecting arm 10 and the semi-circular toothed ring 11. The two meshing transmission gears 9 drive the connecting arm 10 to rotate, causing the semi-circular toothed ring 11 to unfold from its retracted state to cover the end of the steel beam for subsequent inspection. The fifth motor 31 drives the drive gear 32 to rotate, which, in conjunction with the meshing semi-circular toothed ring 11, drives the slide 12 to move along the ring rail. The slide 12 carries the monitoring seat 13 and slides along the semi-circular ring rail, realizing a 360° scan of the steel beam connection part. The sixth motor 33 rotates the monitoring seat 13, and the seventh motor 34 drives the second threaded rod 3. 5. Rotation enables the telescopic arm 15 to move linearly, adjusting the contact distance between the second electromagnetic adsorption seat 16 and the column steel structure for coarse positioning. The eighth motor 37 drives the guide wheel 38 to rotate, thereby rotating the ring seat 18 and changing the orientation of the guide wheel 38. The ninth motor 39 drives the roller 19 to rotate, enabling the ring seat 18 to move along the column. Through the rotation of the roller 19 and the direction of the ring seat 18, millimeter-level fine adjustment of the second electromagnetic adsorption seat 16 is achieved. The electric push rod 36 adjusts the distance between the ring cover 17 and the second electromagnetic adsorption seat 16 to control the adsorption force and avoid overload damage to the steel structure.

[0038] Working principle: The device is placed on the top side of the end of the crossbeam and fixed to the top side of the end of the crossbeam by the first electromagnetic adsorption seat 6. At this time, the crossbeam is lifted by a crane to the installation position. Then, the third motor 28 works, driving the first threaded rod 23 to rotate through the synchronous pulley and synchronous belt, which in turn drives the threaded sliding plate 24 to move, extending the movable rod 7 located in the base 1. At the same time, the seventh motor 34 drives the second threaded rod 35 to rotate, which in turn drives the threaded telescopic arm 15 to move along the linear slide rail until the first... The second electromagnetic adsorption seat 16 is close to the column steel structure. The first motor 20 drives the transmission shaft 21 to rotate, which in turn drives the base 1 to rotate on the first electromagnetic adsorption seat 6. The second motor 25 drives the rotating gear 29 to rotate, which engages with the inner ring gear 27 to drive the base 1 to rotate. This initially adjusts the second electromagnetic adsorption seat 16 to ensure that it is flush with the side of the column steel structure. At this time, the second electromagnetic adsorption seat 16 continues to move until it contacts the side of the column steel structure. By energizing the column steel structure, the second electromagnetic adsorption seat 16 is adsorbed onto the column steel structure.

[0039] The fourth motor 30 drives the two transmission gears 9 to rotate in opposite directions at the same speed. At this time, the connecting arm 10 drives the semi-circular toothed ring 11 to rotate until it covers the outer side of the end of the crossbeam. The fifth motor 31 drives the drive gear 32 to rotate, which engages with the semi-circular toothed ring 11 and drives the slide 12 to move along the semi-circular ring track. The sixth motor 33 drives the monitoring seat 13 to rotate, and then the connection part is viewed through the monitoring camera. At this time, the electric push rod 36 drives the ring cover 17 and the ring seat 18 to move until the roller 19 is in contact with the column steel structure. The side contact reduces the adsorption force between the second electromagnetic adsorption seat 16 and the column steel structure. The ninth motor 39 drives the roller 19 to rotate, and the ring seat 18 moves along the side of the column steel structure. The eighth motor 37 drives the guide wheel 38 to rotate, thereby realizing the rotation of the ring seat 18 and the orientation of the guide wheel 38. Then, when the roller 19 rotates, it can achieve multi-directional fine adjustment of the second electromagnetic adsorption seat 16. After the corresponding adjustment, the electric push rod 36 retracts, increasing the adsorption force between the second electromagnetic adsorption seat 16 and the column steel structure.

[0040] After welding and bolting the crossbeam, the semi-circular toothed ring 11 is adjusted to be close to the connection point. The connection point is then rotated and defect identified by the ultrasonic guided wave sensor, infrared thermal imager, and monitoring camera on the monitoring seat 13, which moves along the semi-circular toothed ring 11. After the inspection is completed, the device is restored to its original state and removed from the end of the crossbeam by a crane.

[0041] The rotating arm 3 and support plate 4, together with the electromagnetic adsorption seat, achieve horizontal / vertical angle adjustment through the first motor 20 and the second motor 25. Combined with the linear displacement of the telescopic arm 15, it forms a free space positioning capability, thereby achieving preliminary adjustment of the crossbeam during the hoisting process. Through the adjustable roller 19 and the adjustable adsorption force of the second electromagnetic adsorption seat 16, and with the cooperation of the ring-moving monitoring camera, the precise positioning of the crossbeam during installation is achieved.

[0042] The first electromagnetic adsorption seat 6 fixes the end of the crossbeam, and the second electromagnetic adsorption seat 16 achieves flexible contact with the column through the combined movement of the roller 19 and the ring seat 18. The adsorption force is adjustable, avoiding positioning deviation caused by rigid collision.

[0043] The rotating scanning monitoring base 13 integrates ultrasonic guided wave to detect bolt loosening, infrared thermal imaging to identify weld defects, and visual monitoring to achieve three-dimensional modeling. It achieves 360° scanning without blind spots through the orbital movement of the semi-circular toothed ring 11, thus improving detection efficiency.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
