Description

Technical Field

[0001] This application belongs to the field of testing devices, and more specifically, relates to a testing device for steel structures used in building engineering. Background Technology

[0002] I-beams, commonly used in steel structures, require welding. After welding, the welds and surfaces of the steel structure need to be inspected to ensure that the I-beams are free of defects.

[0003] See Chinese Patent Publication No. CN120161053A, which discloses a visual inspection device and method for weld seams based on steel structure welding processing, and specifically discloses the following technical contents: It includes a base plate and an industrial computer. Walking mechanisms are provided on both sides of the base plate. A third camera and a fourth camera are fixedly connected to the end of the base plate. An adjustment mechanism is provided at the bottom of the base plate, and a data acquisition mechanism is fixedly connected to one end of the adjustment mechanism. Through the walking mechanisms, and simultaneously through a first electric telescopic rod, a first connecting block, and a second connecting block, the height of the limiting rollers can be adjusted to ensure that the limiting roller closest to the side plate can pass over the side plate first. After passing over, the limiting roller resets, and then the other limiting roller also passes over the side plate through the same steps. This ensures that the inspection of weld seams on the surface of the H-beam is not affected by the side plate, allowing the device to automatically walk and inspect along the H-beam without needing to move the H-beam by a crane, thus facilitating the inspection of weld seams on the surface of the H-beam.

[0004] However, the applicant believes that there is still room for improvement in the inspection of I-beams in steel structures, so that it can be coordinated with the conveying line of the I-beams to detect defects in the I-beams themselves in the conveying line, and that the inspection structure and the cooperating structure can be used alone or in combination without being limited by the production line. Summary of the Invention

[0005] The purpose of this application is to provide a steel structure testing device for building engineering, which can be used in conjunction with an I-beam production line to test I-beams, ensuring the comprehensiveness, flexibility and stability of I-beam testing, so as to avoid hidden dangers caused by defects in the I-beams during subsequent steel structure applications.

[0006] To achieve the above objectives, this application employs the following technical solution: This application discloses a steel structure inspection device for building engineering, including a bottom traveling roller, a top traveling roller, a right traveling roller, and a left traveling roller.

An outer ring is rotatably disposed on the outer circumferential surface of the inner rings, and an outer ring drive assembly is disposed on the outer ring, meshing with the inner ring drive teeth. The paired inner rings are connected by a telescopic adjustment push rod. Each outer ring has a detector ring extending in the direction of the adjacent inner ring. Several detection bases are distributed on the inner surfaces of the detector rings, and these bases are used to mount an inspection device or a video acquisition device for inspecting the I-beam.

[0010] As one of the preferred technical solutions, the steel structure testing device for building engineering further includes a roller frame, which is connected to the base through several frame legs distributed along its own length. Several conveying rollers are distributed along the length of the roller frame. The roller frame is also provided with a tail end limiting plate and a head end limiting plate adapted to the length of the I-beam. The tail end limiting plate is connected to the tail end telescopic cylinder, and the head end limiting plate is connected to the head end telescopic cylinder.

[0012] As one of the preferred technical solutions, the supporting block is provided with block proximity sensors on both sides. The proximity sensors are connected to the controller via electrical signals, and the controller is connected to the hydraulic station of the supporting cylinder via electrical signals.

[0013] Compared with the prior art, the beneficial effects of this application are: 1. This application can achieve movement along the length of the I-beam through its own walking device, and can achieve rotation of several detection bases relative to the I-beam during the movement, thereby improving the detection of the I-beam at different positions and angles, thus improving the accuracy and reliability of the I-beam detection.

[0021] The technical solutions described in this application will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1: As Figures 1 to 5 As shown, a steel structure testing device for building engineering includes a pair of inner rings 27. Adjacent inner rings 27 are connected to telescopic adjustment push rods 30 via ring connecting seats 28. The ring connecting seats 28 are located at the top and bottom ends of the inner rings 27. Transmission gearboxes 22 are respectively provided on both sides of the ring connecting seats 28. The transmission gearboxes 22 are respectively connected to the top traveling roller 33, the right traveling roller 24, the bottom traveling roller 23, and the left traveling roller 34, so that the top traveling roller 33, the right traveling roller 24, the bottom traveling roller 23, and the left traveling roller 34 form a space inside the inner rings 27 to accommodate the I-beams 10. The inner ring body 27 has an inner ring drive tooth 32 and an outer ring body 17 that rotates relative to the inner ring body 27 on its circumferential outer side. The outer ring body 17 achieves relative rotation with the inner ring drive tooth 32 through the meshing of the outer ring drive assembly 31. A bearing structure may be provided at the connection position between the inner ring body 27 and the outer ring body 17. The outer ring drive assembly 31 includes a drive motor and a drive gear connected to the output shaft of the drive motor. The outer ring drive assembly 31 is driven by the meshing of the drive gear and the inner ring drive tooth 32. The outer ring body 17 has a detector ring body 20 extending in the direction of the adjacent inner ring body 27. The detector ring body 20 has several detection bases 25 on its circumferential inner side. The detection bases 25 are used to install different detection devices and video acquisition devices. The transmission gearboxes 22 on both sides of the top of the inner ring body 27 are also provided with a travel drive motor 26.

[0023] In this embodiment, the inner ring body 27 can move along both sides, the upper end face, and the lower end face of the I-beam 10 via the right traveling roller 24, the left traveling roller 34, the bottom traveling roller 23, and the top traveling roller 33. Furthermore, in this application, the inner ring body 27 can serve as the base structure for the outer ring body 17 and the detector ring body 20, enabling the rotation of the aforementioned structures relative to the inner ring body 27, thereby achieving adjustment of the detection angle and detection position.

[0024] In this embodiment, the inner ring body 27 has a trapezoidal cross-section, and a plurality of inner ring drive teeth 32 and ring body positioning holes 18 are machined on its circumferential outer surface. The inner ring drive teeth 32 can cooperate with the outer ring drive assembly 31 on the outer ring body 17 to realize the rotation of the outer ring body 17 and its integrated detector ring body 20 with the inner ring body 27. The ring body positioning holes 18 can cooperate with the ring body positioning holes 18 on the detector ring body 20, and the connection between the two is realized through the ring body locator 19 on the outer ring body 17.

[0025] In this application, both ends of the right traveling roller 24, left traveling roller 34, bottom traveling roller 23, and top traveling roller 33 are connected to the corresponding transmission gearbox 22. A traveling drive motor 26 is provided at the transmission gearbox 22 at the top of the inner ring body 27 to input power into the transmission gearbox 22. Specifically, see... Figures 1 to 3 As shown, the two ends of the top traveling roller 33 are connected to the transmission gearboxes 22 on both sides to achieve forced synchronization of the two transmission gearboxes 22. Since the transmission gearboxes 22 connected to the top ends of the left traveling roller 34 and right traveling roller 24 have traveling drive motors 26, the left and right traveling rollers 34 and 24 can transmit power from the upper transmission gearbox 22 to the lower transmission gearbox 22, so that the lower transmission gearbox 22 can drive the bottom traveling roller 23. The two ends of the bottom traveling roller 23 are connected to the transmission gearboxes 22, and forced synchronization of the two transmission gearboxes 22 is achieved.

[0026] In this embodiment, the inner rings 27 are arranged in pairs, and adjacent inner rings 27 are connected by a ring connecting seat 28, a ring guide rod 29, and a telescopic adjustment push rod 30. The telescopic adjustment push rod 30 can be a bidirectional push rod motor or a unidirectional push rod motor, which can realize the adjustment of the distance between adjacent inner rings 27.

[0027] In this embodiment, the detection base 25 is used to install the detection device or detection sensor, video acquisition device, etc., and the detection base 25 is fixedly connected to the inner side of the detector ring 20 so as to follow the movement of the detector ring 20, thereby realizing the detection of the side of the I-beam 10 at different angles.

[0028] In this embodiment, the outer ring drive assembly 31 can drive the drive gear through the drive motor, and the drive gear can mesh with the inner ring drive gear 32 to achieve transmission, so that the outer ring drive assembly 31 drives the outer ring body 17 and the detector ring body 20 to reciprocate at a certain angle.

[0029] Example 2: As Figures 1 to 5 As shown in Embodiment 1, a steel structure testing device for building engineering includes a pair of ring guide rods 29 on the ring connecting seat 28. The ring guide rods 29 move relative to the ring connecting seat 28, and a linear motion bearing is provided at the connection point between them. A support shaft 21 is also provided between the vertically adjacent transmission gearboxes 22 on the same side of the inner ring 27. The support shaft 21 is connected to the auxiliary roller 15 via an auxiliary support 16.

[0030] The detector ring 20 and inner ring 27 are machined with a plurality of ring positioning holes 18, which are evenly distributed around the circumference of the detector ring 20 and inner ring 27. The outer ring 17 is also provided with a ring locator 19, which includes a mounting plate that is mounted to the outer ring 17. A push rod motor is mounted on the mounting plate, and the push rod of the push rod motor passes through the ring positioning holes 18 on the detector ring 20 and inner ring 27 in sequence.

[0031] In this embodiment, the ring guide rod 29 can assist and guide the telescopic adjustment push rod 30 through relative movement with the ring connecting seat 28, facilitating the stable adjustment. The bracket shaft 21, connected to the auxiliary roller 15 via the auxiliary bracket 16, enables the auxiliary roller 15 to contact both sides of the I-beam 10, cooperating with the right traveling roller 24, left traveling roller 34, bottom traveling roller 23, and top traveling roller 33 to satisfy the movement of the inner ring 27 and its associated structures on the I-beam 10, and improve stability and reliability. In this embodiment, torsion springs are provided at the connection points between the two ends of the bracket shaft 21 and the corresponding positions of the transmission gearbox 22. The torsion springs apply force to make the auxiliary roller 15 fit against the side of the I-beam 10.

[0032] In this embodiment, the ring positioning hole 18 can meet the temporary positioning needs of the outer ring 17 and the inner ring 27. Specifically, the ring positioner 19 extends into the ring positioning hole 18 in the detector ring 20 and the inner ring 27 respectively through the extension end of the push rod motor. The alignment of the two rings is achieved by aligning the two ring positioning holes 18, thereby satisfying the stability and reliability of the detection process.

[0033] Example 3: As Figures 1 to 5As shown, based on Embodiment 1 or Embodiment 2, a steel structure testing device for building engineering further includes a roller frame 2. The roller frame 2 is connected to a base via several frame legs 3 distributed along its length. A conveyor roller 1 is arranged on the roller frame 2 along its direction. A frame base plate 4 is located below the conveyor roller 1 and is connected to the frame legs 3. The frame base plate 4 is also equipped with a tail-end telescopic cylinder 6, a support cylinder 7, and a head-end telescopic cylinder 11. The tail-end telescopic cylinder 6 and the head-end telescopic cylinder 11 are located at the tail end and head end of the I-beam 10 workstation, respectively. The telescopic end of the tail-end telescopic cylinder 6 is connected to a tail-end limiting plate 5, which is located between adjacent conveyor rollers 1. The telescopic end of the head-end telescopic cylinder 11 is connected to a head-end limiting plate 12, which is located between adjacent conveyor rollers 1. The supporting cylinders 7 are a plurality of cylinders distributed along the length of the I-beam 10. A plurality of supporting blocks 8 are connected to the telescopic ends of the supporting cylinders 7. A plurality of block proximity sensors 35 are distributed on the sides of the supporting blocks 8 along the movement direction of the I-beam 10. The block proximity sensors 35 are connected to the controller via electrical signals. The controller is connected to the hydraulic stations of the tail end limit plate 5, the supporting cylinders 7, and the head end telescopic cylinder 11 via electrical signals.

[0034] In this embodiment, the first-end telescopic cylinder 11 drives the first-end limiting plate 12 to limit and stop the I-beam 10 fed by the conveyor roller 1. At this time, the conveyor roller 1 also needs to stop conveying. The last-end telescopic cylinder 6 drives the last-end limiting plate 5 to achieve secondary limiting of the I-beam 10 in the conveying direction.

[0035] Meanwhile, in this embodiment, the roller frame 2 is provided with a number of side positioning cylinders 9 on both sides. The telescopic ends of the side positioning cylinders 9 are connected to side push plates 13. The side push plates 13 can adjust the position of the I-beam 10 on the roller frame 2 from both sides.

[0036] In this embodiment, after the left and right adjustments are completed, the side push plate 13 is reset under the drive of the side positioning cylinder 9, and the tail end telescopic cylinder 6 and the head end telescopic cylinder 11 drive the tail end limiting plate 5 and the head end limiting plate 12 to reset.

[0037] In this embodiment, the supporting cylinder 7 is positioned below the adjusted I-beam 10 and supports the I-beam 10 via the supporting block 8 connected to its telescopic end. The supporting cylinder 7 drives the supporting block 8 upward through its telescopic end until the I-beam 10 disengages from the conveyor roller 1, and the disengagement height is sufficient for the operation of components such as the inner ring 27.

[0038] In this embodiment, the supporting block 8 can detect the approach of the inner ring 27 through the block proximity sensors 35 on both sides. After the inner ring 27 approaches, the supporting block 8 at that position is reset by the supporting cylinder 7. After the inner ring 27 and other detection devices move to the next supporting block 8, the previous supporting block 8 is reset by the supporting cylinder 7. This process is repeated until the inner ring 27 has traveled along the length of the I-beam 10.

[0039] Finally, although the technical solutions described in this application are based on the preferred embodiments, any recombination of the technical solutions described in this application by those skilled in the art based on their prior knowledge of the prior art should be understood as still within the scope of protection of this application and subject to its protection.
