Description

Technical Field

[0001] This invention relates to the field of laser measurement technology, specifically to a laser measurement device and method for building steel structures. Background Technology

[0002] As the main load-bearing structure of modern buildings, the dimensions, installation accuracy, and surface defects of steel structures directly affect the overall safety of buildings. Laser measurement is currently the mainstream method for steel structure inspection, which requires high flexibility, stability, and accuracy of the measuring device.

[0003] Most existing laser measuring devices can only perform single-direction and fixed-angle detection, and cannot rotate around the steel structure for scanning. This results in blind spots in the detection. Furthermore, the laser probe has poor stability during movement and is inconvenient for clamping the steel structure, which can easily lead to large measurement errors and low operating efficiency. As a result, they cannot meet the high-precision and full-coverage detection requirements of construction sites.

[0004] To address the shortcomings of existing devices, such as limited detection range, insufficient operational stability, and cumbersome clamping and fixing, there is an urgent need for a dedicated laser measuring device for building steel structures that can rotate omnidirectionally, scan smoothly, and clamp automatically, in order to improve detection accuracy and work efficiency. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a laser measuring device and method for building steel structures, solving the problems mentioned in the background section.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a laser measuring device for building steel structures, comprising a base plate, with support plates fixedly connected to both the left and right sides of the upper surface of the base plate. An annular limiting groove is formed on the inner side of the support plate, and a limiting ring is movably inserted into the annular limiting groove. An installation ring is fixedly connected to the inner side of the limiting ring. A toothed ring is fixedly sleeved on the outer surface of the left installation ring. Limit seats are fixedly connected to both the front and rear sides of the left side of the right installation ring. Drive motors are fixedly connected to both the front and rear sides of the right side of the left installation ring. A lead screw is fixedly connected to the output end of the machine. The right end of the lead screw is movably inserted into a limit seat. A limit rod is fixedly connected to the inner side of the mounting ring. A connecting block is movably sleeved on the left side of the outer surface of the limit rod. A connecting ring is fixedly connected to the inner side of the connecting block. A laser detector is fixedly inserted into the outer surface of the connecting ring. Transmission blocks are fixedly connected to both the front and rear sides of the outer surface of the connecting ring. The transmission blocks are threadedly sleeved with the outer surface of the lead screw. A reduction motor is fixedly connected to the left side of the upper surface of the base plate. A transmission gear is fixedly connected to the output end of the reduction motor. The transmission gear meshes with a gear ring.

[0007] Preferably, a support frame is fixedly connected to the middle of the outer side of the support plate, an electric push rod is fixedly connected to the inner wall of the support frame, the electric push rod passes through the middle of the outer side of the support plate, and a clamping head is fixedly connected to the output end of the electric push rod, with the inner side of the clamping head clamping the steel structure body.

[0008] Preferably, a rubber pad is fixed to the inner side of the clamping head.

[0009] Preferably, a reinforcing member is fixedly connected to the bottom of the outer side of the support plate, and the lower surface of the reinforcing member is fixedly connected to the upper surface of the base plate.

[0012] Preferably, a fixing ring is fixedly sleeved on both the left and right sides of the outer surface of the limiting rod, and the outer side of the fixing ring is fixedly connected to the inner side of the mounting ring.

[0013] The present invention further provides a method for using a laser measuring device for building steel structures, comprising the following steps: Step 1: Place the steel structure body between the two clamping heads, start the electric push rod to drive the clamping heads to clamp the steel structure body, and achieve fixed positioning; Step 2: Start the reduction motor, which drives the installation to rotate around the annular limiting groove to the preset measurement angle through the meshing of the transmission gear and the gear ring. Step 3: Start the drive motor to rotate the lead screw, causing the transmission block to move along the lead screw axis, which in turn causes the connecting ring and the laser detector to move smoothly along the limit rod, performing continuous laser measurement on the steel structure body. Step 4: Adjust the rotation angle of the mounting ring using the geared motor, and work with the drive motor to achieve multi-angle, full-coverage detection by the laser detector; Step 5: Stop the drive motor and the reduction motor, control the electric push rod to reset, release the clamping head and remove the steel structure body.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a laser measuring device and method for building steel structures, which has the following beneficial effects: 1.

Combined with the dual guiding positioning of screw drive and limit rod, the laser detector can stably translate along the axial direction of the steel structure, realizing continuous scanning and detection of the building steel structure from all angles without blind spots. This fundamentally solves the problems of limited measurement range and blind spots in traditional devices, and greatly improves the integrity and accuracy of measurement data.

[0015] 2. The laser measuring device and method for building steel structures uses an electric push rod automatic clamping mechanism to quickly fix the steel structure body.

At the same time, it significantly simplifies the clamping and debugging process, and improves the work efficiency, ease of operation and long-term stability of on-site testing of building steel structures.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-5This invention provides a technical solution: a laser measuring device for building steel structures, comprising a base plate 1, with support plates 2 fixedly connected to both the left and right sides of the upper surface of the base plate 1. An annular limiting groove 3 is formed on the inner side of the support plate 2, and a limiting ring 4 is movably inserted into the annular limiting groove 3. An mounting ring 5 is fixedly connected to the inner side of the limiting ring 4. A toothed ring 6 is fixedly sleeved on the outer surface of the mounting ring 5 on the left side. Limit seats 7 are fixedly connected to both the front and rear sides of the left side of the mounting ring 5 on the right side. A drive motor 8 is fixedly connected to both the front and rear sides of the right side of the mounting ring 5 on the left side. The output end of the drive motor 8 is fixedly connected to... The lead screw 9 is movably inserted into the limit seat 7 at its right end. The inner side of the mounting ring 5 is fixedly connected to the limit rod 10. The left side of the outer surface of the limit rod 10 is movably sleeved with the connecting block 11. The inner side of the connecting block 11 is fixedly connected to the connecting ring 12. The outer surface of the connecting ring 12 is fixedly inserted with the laser detector 13. The front and rear sides of the outer surface of the connecting ring 12 are fixedly connected with the transmission block 14. The transmission block 14 is threadedly sleeved with the outer surface of the lead screw 9. The left side of the upper surface of the base plate 1 is fixedly connected with the reduction motor 15. The output end of the reduction motor 15 is fixedly connected with the transmission gear 16, which meshes with the gear ring 6.

[0020] In this invention, in order to achieve stable fixation of the steel structure body 20 and avoid deviation and shaking during measurement, the support frame 17, the electric push rod 18 and the clamping head 19 are used to automatically clamp the steel structure body, thereby improving measurement accuracy and stability.

[0021] In this invention, in order to protect the surface of the steel structure body 20 from being scratched by the clamping head 19, and at the same time increase the clamping friction to prevent slippage, a rubber pad is provided on the inner side of the clamping head 19 to balance protection and clamping stability.

[0022] In this invention, in order to enhance the connection strength between the support plate 2 and the base plate 1 and prevent the support plate 2 from deforming or loosening after long-term use, a reinforcement member 21 is added to the bottom of the support plate 2 to improve the overall structural rigidity of the device.

[0023] In this invention, in order to reduce vibration transmission during device operation, improve placement stability and reduce noise, a rubber base 22 is provided on the underside of the base plate 1 to provide cushioning and anti-slip function.

[0024] In this invention, in order to strengthen the connection between the limiting seat 7 and the right mounting ring 5 and prevent the limiting seat 7 from falling off when the lead screw 9 rotates, a reinforcing ring is sleeved on the outside of the limiting seat 7 to improve the local structural strength.

[0025] In this invention, in order to prevent the limiting rod 10 from moving axially and to ensure the precise and stable movement path of the laser detector 13, fixing rings are added to both sides of the limiting rod 10 to achieve reliable positioning of the limiting rod 10.

[0026] The present invention further provides a method for using a laser measuring device for building steel structures, comprising the following steps: Step 1: Place the steel structure body 20 between the two clamping heads 19, and start the electric push rod 18 to drive the clamping heads 19 to clamp the steel structure body 20 to achieve fixed positioning; Step 2: Start the reduction motor 15, which drives the mounting ring 5 to rotate around the annular limiting groove 3 to the preset measurement angle through the transmission gear 16 meshing with the gear ring 6. Step 3: Start the drive motor 8 to drive the lead screw 9 to rotate, so that the transmission block 14 moves along the axis of the lead screw 9, and drives the connecting ring 12 and the laser detector 13 to move smoothly along the limit rod 10 to perform continuous laser measurement on the steel structure body 20. Step 4: Adjust the rotation angle of the mounting ring 5 by using the reduction motor 15, and cooperate with the drive motor 8 to achieve multi-angle, full-coverage detection by the laser detector 13; Step 5: Stop the drive motor 8 and the reduction motor 15, control the electric push rod 18 to reset, release the clamping head 19 and remove the steel structure body 20.

[0027] In use, first place the entire device stably on the testing site using the rubber base 22 under the base plate 1, ensuring the device is stable and does not wobble. Then, place the steel structure body 20 to be tested horizontally in the center between the two sets of clamping heads 19. Start the electric push rod 18, which extends stably under the support of the support frame 17, pushing the clamping heads 19 to move slowly inward. The rubber pads on the inner side of the clamping heads 19 evenly clamp the steel structure body 20, completing the positioning and fixing of the steel structure body 20 and preventing displacement or deflection during the measurement process. Then, start the reduction motor 15, which drives the transmission gear 16 to rotate at a constant speed. The transmission gear 16 meshes with the gear ring 6, thereby driving the mounting rings 5 ​​on both sides to rotate stably along the annular limiting groove 3 on the inner side of the support plate 2 through the limiting ring 4. Next, start the drive motor 8, which drives the lead screw 9 to rotate stably. The rod 9 is threadedly engaged with the transmission block 14, which drives the transmission block 14 to move smoothly along the axial direction of the lead screw 9. At the same time, the connecting block 11 slides synchronously along the limiting rod 10, providing guidance and limiting for the connecting ring 12 and the laser detector 13, so that the laser detector 13 moves at a uniform speed along the length of the steel structure body 20, realizing continuous and stable laser scanning measurement. During the measurement process, the rotation angle of the mounting ring 5 can be flexibly adjusted by the reduction motor 15 according to the detection requirements, so as to realize all-round blind-spot-free detection of different sides and angles of the steel structure body 20. After all the measurement operations are completed, the drive motor 8 and the reduction motor 15 are stopped in sequence, so that the laser detector 13 and the mounting ring 5 stop moving. Then, the electric push rod 18 is controlled to retract and reset, which drives the clamping head 19 to release the steel structure body 20. Finally, the steel structure body 20 that has been inspected is removed, thus completing the entire laser measurement operation process of the building steel structure.

[0028] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.
