Description

Technical Field

[0001] The invention relates to the field of steel structure grid production and processing, in particular to a steel structure grid production correction device. Background Art

[0002] As a form of steel structure, steel structure grid plays an important role in the construction field. The following are the main functions of steel structure grid: Forming a large space: Steel structure grids can form an open, column-free large space to meet the space requirements of public buildings such as large gymnasiums, exhibition halls, conference halls, theaters, etc. This structural form provides more possibilities for architectural design and can adapt to the requirements of modern cities for diversified and personalized architecture.

[0003] Dispersed load: Steel structure grid can disperse the load on the building structure to each supporting point, so as to better bear the larger load. This ability to disperse the load makes the steel structure grid have a significant advantage in bearing weight and improves the safety of the building.

[0004] Improve structural rigidity: Steel structure grid can improve the overall rigidity of the building structure, making the building more stable. This stability is crucial for the long-term use and maintenance of the building, and can effectively prevent deformation and damage during long-term use.

[0005] Light weight and high strength: Steel structure grid is made of light steel, which has the characteristics of light weight, can reduce the weight of the building and reduce the cost of foundation engineering. At the same time, the strength and toughness of steel are very high, which makes the strength and stability of steel structure grid also very high, and it is not easy to deform and break.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below through specific implementation methods.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, the present invention provides a steel structure grid production correction device, comprising a correction base plate 1, wherein the front and rear sides of the upper end of the correction base plate 1 are fixedly connected with a steel frame fixing device 2, wherein the steel frame fixing device 2 comprises a support fixing plate 21, wherein the support fixing plate 21 is fixedly connected to the correction base plate 1, wherein a correction guide fixing sleeve 23 is rotatably connected to the middle position of the upper end of the support fixing plate 21, wherein a centripetal sliding groove 231 is provided on the correction guide fixing sleeve 23, wherein the centripetal sliding groove 231 is evenly distributed along the circumference of the correction guide fixing sleeve 23, wherein a centripetal fixing rod 24 is slidably connected in the centripetal sliding groove 231, wherein a side of the centripetal fixing block facing the central axis of the correction guide fixing sleeve 23 is rotatably connected with a plurality of push-forward wheels 25 evenly distributed along the front and rear directions, wherein the middle of the push-forward wheels 25 is a wheel motor, and the opposite ends of the correction guide fixing sleeve 23 are fixedly connected with a straight guide disk 26 The straight guide disk 26 is provided with a radial moving groove 261 along its radial direction. There are multiple radial moving grooves 261 evenly distributed along the circumference of the straight guide disk 26, and the number and position of the radial moving grooves 261 correspond to the centripetal sliding grooves 231 one by one. A radial sliding rod 27 is slidably connected in the radial moving groove 261. The radial sliding rod 27 is fixedly connected to the centripetal fixed rod 24. A synchronous rotating plate 28 is rotatably connected to the straight guide disk 26. The synchronous rotating plate 28 is provided with a synchronous groove 281 corresponding to the radial sliding rod 27, which has one end close to the central axis of the synchronous rotating plate 28 and the other end away from the central axis of the synchronous rotating plate 28 and is inclined. The radial sliding rod 27 and the synchronous groove 281 are slidably connected. An eccentricity detection device 3 is provided in the middle position of the two steel frame fixing devices 2, and a steel beam correction mechanism 4 is provided between the eccentricity detection device 3 and the front steel frame fixing device 2.

[0024] It should be noted that in the process of correcting the steel structure main beam, the steel structure main beam is passed through the front and rear steel frame fixing devices 2, the eccentricity detection device 3 and the steel beam correction mechanism 4, and the steel structure main beam is fixed by the steel frame fixing device 2. In this process, the wheel motor in the middle position of the advancing wheel 25 drives the advancing wheel 25 to rotate, and the advancing wheel 25 drives the steel structure main beam to move along the front and rear directions. In this process, the eccentricity detection device 3 will detect the bending degree of the steel structure main beam. After detecting that the steel structure main beam is bent at a certain point, a rotating gear 101 is provided on the outer fixing sleeve of the correction guide fixing sleeve 23, and a driving gear 102 is also rotatably connected to the support fixing plate 21, and the driving gear 102 is meshed with the rotating gear 101. A deflection motor 103 is also fixedly mounted on the support fixing plate 21, and the deflection motor 103 is coaxially fixedly connected to the driving gear 102 and rotates, driving the gear 102 and the rotating gear The wheels 101 mesh with each other and rotate the correction guide fixing sleeve 23, thereby causing the steel frame fixing device 2 to drive the steel structure main beam to rotate as a whole, so that the steel structure main beam rotates until its bending part is horizontal. When the bending part on the steel structure main beam moves into the steel beam correction mechanism 4, the steel structure main beam is corrected by the steel beam correction mechanism 4. In the process of fixing the steel structure main beam by the steel frame fixing device 2, a relative rotation is generated between the synchronous rotating plate 28 and the straight guide plate 26 by providing a pushing hydraulic rod. During this process, the synchronous groove 281 and the radial sliding rod 27 slide relative to each other, so that the radial sliding rod 27 drives the centripetal fixing rod 24 to approach the steel structure main beam. Finally, the steel structure main beam is clamped by pushing the advancing wheel 25. Through the above-mentioned technical scheme, the bending part of the steel structure main beam can be automatically checked, and the bending part can be sent to the steel beam correction mechanism 4 for correction, which greatly reduces manpower and material resources.

[0025] like Figures 5 to 9 As shown, the eccentricity detection device 3 includes an eccentric control fixed disk 31, and the eccentric control fixed disk 31 is fixedly installed at the upper end of the middle position of the correction base plate 1. The eccentric control fixed disk 31 is in a circular ring shape as a whole. The middle position of the eccentric control fixed disk 31 is rotatably connected with a circumferential rotating ring 32, and the middle position of the circumferential rotating ring 32 is fixedly mounted with a detection fixed ring 33 coaxial with it. The detection fixed ring 33 is fixedly connected with a detection fixed rod 34 along its radial direction. The detection fixed rod 34 is in a cylindrical shape as a whole and is hollow in the middle. The middle of the detection fixed rod 34 is slidably connected with a rolling contact mechanism 5 along the radial direction of the detection fixed ring 33. A compression spring 35 is arranged between the inside of the detection fixed rod 34 and the rolling contact mechanism 5. A distance measuring module 36 for detecting the radial runout of the rolling contact mechanism 5 along the detection fixed ring 33 is also fixedly installed on the detection fixed rod 34.

[0026] It should be noted that, in the process of detecting the degree of bending of the steel structure main beam through the eccentricity detection device 3, when the rolling contact mechanism 5 is in contact with the steel structure main beam, and when the steel structure main beam moves along the front and rear directions, when the bending part of the steel structure main beam contacts the rolling contact mechanism 5, the rolling contact mechanism 5 will move along the radial direction of the detection fixing ring 33, and the distance measurement module 36 is a laser ranging module, which will detect the moving distance of the rolling contact mechanism 5.

[0027] like Figures 5 to 9 As shown, the rolling contact mechanism 5 includes a beating detection rod 51, a reflection rod 511 for reflecting the signal of the distance measurement module 36 is fixedly connected to the beating detection rod 51, the beating detection rod 51 is slidably connected to the detection fixing rod 34, a spring receiving groove 341 is provided in the middle position of the detection fixing rod 34, a compression spring 35 is placed in the spring receiving groove 341, and the two ends of the compression spring 35 are respectively fixedly installed at one end of the spring receiving groove 341 away from the central axis of the detection fixing ring 33 and the beating detection rod 51. One end away from the central axis of the detection fixing ring 33 is fixedly connected, and a rotation detection rod 52 is arranged in the middle of the jumping detection rod 51, and one end of the rotation detection rod 52 close to the central axis of the detection fixing ring 33 is fixedly connected to a rolling detection seat 53, and a detection roller 54 is rotatably connected to the middle position of the rolling detection seat 53, and a linkage mechanism 6 for driving the detection roller 54 to rotate is arranged on the rotation detection rod 52, and a tensioning transmission mechanism 7 for driving the linkage mechanism 6 is arranged between the detection fixing ring 33 and the jumping detection rod 51.

[0028] It should be noted that, in the process of the rolling contact mechanism 5 contacting the steel structure main beam, the detection roller 54 contacts the outer surface of the steel structure main beam. During this process, the compression spring 35 will apply pressure to the jump detection rod 51, so that the detection roller 54 is pressed against the surface of the steel structure main beam and rotates autonomously as the steel structure main beam moves forward and backward. In this process, the rotation of the detection roller 54 is driven by the tensioning transmission mechanism 7.

[0029] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the tensioning transmission mechanism 7 includes a first tensioning transmission roller 71, a second tensioning transmission roller 72, a tensioning transmission belt 73, a tensioning sliding block 74 and a tensioning spring 75. The detection fixing ring 33 is provided with a tensioning sliding groove 331 at the front end located on the left and right sides of the detection fixing rod 34. The tensioning sliding groove 331 is slidably connected with the tensioning sliding block 74. The second tensioning transmission roller 72 is rotatably connected to the tensioning sliding block 74. The tensioning sliding groove 331 is also fixed with a tensioning sliding block 74 that is slidably connected with the tensioning sliding block 74. The spring mounting rod 76 is connected, and a tensioning spring 75 is sleeved on the spring mounting rod 76. The two ends of the tensioning spring 75 are respectively fixedly connected to the tensioning sliding block 74 and the tensioning sliding groove 331 at one end away from the detection fixed rod 34. The jumping detection rod 51 is fixedly connected to the roller mounting rod 512, and the roller mounting rod 512 is rotatably connected to the first tensioning transmission roller 71 for driving the linkage mechanism 6. All the first tensioning transmission rollers 71 and the second tensioning transmission rollers 72 are connected together by a tensioning transmission belt 73.

[0030] By fixing a driving motor on one of the rolling mounting rods, and coaxially fixing the driving motor with the first tensioning transmission roller 71 thereon through the output shaft of the driving motor, and driving the first tensioning transmission roller 71 to rotate, the first tensioning transmission roller 71 drives the remaining first tensioning transmission roller 71 and the second tensioning transmission roller 72 to rotate through the tensioning transmission belt 73, and the second transmission roller drives the linkage mechanism 6, thereby rotating the detection roller 54. During this process, under the top pressure of the tensioning spring 75, the tensioning transmission belt 73 and the first tensioning transmission roller 71 and the second tensioning transmission roller 72 can always be in a close contact state, thereby ensuring a good transmission state, and by adjusting the rotation speed of the driving motor and the wheel motor in the advancing wheel 25, the detection roller 54 and the outer surface of the steel structure main beam are in a rolling contact state.

[0031] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the linkage mechanism 6 includes an intermediate transmission bevel gear 61, a first transmission bevel gear 62 and a second transmission bevel gear 63.

The second transmission bevel gear 63 is coaxially fixedly connected to the first linkage roller 64. The detection roller 54 is coaxially fixedly connected to the second linkage roller 65. The first linkage roller 64 and the second linkage roller 65 are driven by a linkage belt 66.

[0032] like Figure 5 and Figure 7 As shown, one end of the detection fixing rod 34 away from the detection fixing ring 33 is fixedly connected to a rotating ring sleeve 8, and an inclined lifting groove 81 is opened inside the rotating ring sleeve 8. The rotating detection rod 52 rotates through the jumping detection rod 51 and slides through the detection fixing rod 34, and the rotating detection rod 52 passes through the middle of the clamping spring 35, and the rotating detection rod 52 and the lifting groove 81 are slidably connected.

[0033] The first tensioning transmission roller 71 drives the rotation of the first transmission bevel gear 62, the first transmission bevel gear 62 drives the rotation of the intermediate transmission bevel gear 61, the intermediate transmission bevel gear 61 drives the rotation of the second transmission bevel gear 63, the second transmission bevel gear 63 drives the rotation of the first linkage roller 64, the first linkage roller 64 drives the rotation of the second linkage roller 65 through the linkage belt 66, and the second linkage roller 65 drives the rotation of the detection roller 54. At the same time, in the process of the jumping detection rod 51 and the rotation detection rod 52 moving along the detection fixing rod 34, the rotation detection rod 52 and the lifting slide groove 81 are slidably connected and rotated, and the rotation detection rod 52 will drive the rolling detection seat 53 and the detection roller 54 to rotate, so that the detection roller 54 makes a spiral movement along the steel structure main beam, so that the bending degree of each part of the steel structure main beam can be detected, thereby improving the accuracy of the detection of the steel structure main beam.

[0034] like Figure 6 and Figure 7 As shown, a first angle sensor 521 is provided between the jumping detection rod 51 and the rotation detection rod 52 , and a second angle sensor 531 is provided at the rotation connection between the rolling detection seat 53 and the detection roller 54 .

[0035] The rotation angle of the rotating detection rod 52 can be measured by the first angle sensor 521, and the angular velocity of the detection roller 54 during the rotation process can be measured by the second angle sensor 531. The rotation speed of the detection roller 54 can be measured in combination with the diameter of the detection roller 54. According to the rotation angle of the rotating detection rod 52 and the rotation speed of the detection roller 54, the rotation speed of the wheel motor in the advancing wheel 25 is adjusted, so that the detection roller 54 and the main beam of the steel structure are always in a state of rolling contact.

[0036] like Figure 4 As shown, the steel beam correction mechanism 4 includes a hydraulic extrusion seat 41 and a hydraulic clamp 42. The hydraulic extrusion seat 41 is symmetrically arranged on the left and right sides of the correction base plate 1. The hydraulic extrusion seat 41 is fixedly installed on the correction base plate 1. The opposite ends of the hydraulic extrusion seat 41 are slidably connected with the hydraulic clamp 42. The middle position of the hydraulic clamp 42 is set in a semicircular shape. A plurality of hydraulic columns 43 are arranged inside the hydraulic clamp 42 and the hydraulic extrusion seat 41.
