Description

Technical Field

[0001] This invention relates to the field of girder formwork inspection equipment, specifically a laser flatness inspection device for girder formwork processing. Background Technology

[0002] The cap beam formwork is a key mold used to form cap beams in bridge construction. The cap beam is a key load-bearing component located on top of the pier, used to support, distribute and transfer the load of the superstructure. The main function of the cap beam formwork is to provide shape and size support for the newly poured concrete, ensure the accuracy of the cap beam's design geometry, axial position, elevation and relative position of each part, and guarantee the appearance quality of the concrete after it is formed.

[0003] To ensure the accuracy of the cast-in-place beam, the formwork needs to be tested for flatness before casting. This ensures that the cast-in-place beam has a smooth surface. The core equipment for testing the flatness of the cast-in-place beam formwork is a laser scanning measurement system. The laser profilometer is one of the devices used for testing the flatness of the cast-in-place beam formwork. Before the flatness test, the surface of the cast-in-place beam formwork needs to be cleaned. Otherwise, concrete residue, oil stains, rust, and other attachments on the surface of the cast-in-place beam formwork will block the laser, causing false defects in the scanning test data and affecting the judgment of flatness.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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] Example 1: Please see Figure 1-10 A laser flatness testing device for processing cap beam templates includes a testing platform 1. The horizontal part of the testing platform 1 has an inner groove 11. A support slider 14 is slidably connected inside the inner groove 11. A placement frame 2 is fixed to the top of the support slider 14. A fixing frame 3 is fixed to one end of the testing platform 1. A lifting plate 31 is slidably connected inside the fixing frame 3. First springs 32 are fixed to both sides of the top of the lifting plate 31. The first springs 32 are fixed to the fixing frame 3. A hot air cavity 33 is opened inside the lifting plate 31. A fan blade roller 34 is rotatably connected inside the top of the lifting plate 31. A third motor 35 is fixed to one side of the top of the lifting plate 31. One end of the fan roller 34 passes through the lifting plate 31 and is fixed to the output shaft of the third motor 35. An electric heating wire 36 is fixed inside the lifting plate 31. An air guide 37 is opened on one side of the bottom of the lifting plate 31. An external frame 4 is fixed to the side of the lifting plate 31 away from the detection platform 1. A first electromagnet 41 is fixed to the top of the inner cavity of the external frame 4. An elastic rope 42 is fixed to the bottom of the first electromagnet 41. A magnetic plate 43 is fixed to the bottom of the elastic rope 42. A scraper 44 is fixed to the bottom of the magnetic plate 43. A second motor 12 is fixed at the end of the testing platform 1 away from the fixed frame 3. A second lead screw 13 is rotatably connected inside the inner slide groove 11. One end of the second lead screw 13 passes through the testing platform 1 and is fixed to the output shaft of the second motor 12. A cover plate 311 is hinged to the top of the lifting plate 31. Wind baffles 312 are slidably connected to the bottom of both sides of the lifting plate 31. Adjustment grooves 101 are opened on the top of both sides of the testing platform 1. A first lead screw 102 is rotatably connected inside one of the adjustment grooves 101. A limit rod 103 is fixed inside the adjustment groove 101 without the first lead screw 102. A first motor 104 is fixed at the end of the testing platform 1 near the first lead screw 102. One end of the first lead screw 102 passes through the adjustment groove 101 and is fixed to the output shaft of the first motor 104. Support frames 105 are slidably connected to the surfaces of both adjustment slots 101. One support frame 105 is threadedly connected to the first lead screw 102, and the other support frame 105 is slidably connected to the limiting rod 103. A lifting slot 106 is provided on the vertical part of the support frame 105. A screw 107 is fixed at the bottom of the lifting slot 106. A support nut 108 is threadedly connected to the surface of the screw 107. A horizontal plate is slidably connected to the surfaces of the two screws 107 above the support nut 108, and a laser profilometer assembly 109 is fixed at the bottom of the horizontal plate. A limiting plate 201 is fixed to the top of the end of the placement frame 2 away from the detection platform 1. Rollers 202 are rotatably connected to both sides of the end of the placement frame 2 near the limiting plate 201. Specifically, in actual operation, the cover beam template is first lifted to the top of the placement frame 2 by a forklift or crane. Then, the second motor 12 is started by the controller, and the second screw 13 is rotated by the second motor 12. The second screw 13 drives the support slider 14 to slide inside the inner slide groove 11, so that the support slider 14 drives the placement frame 2 and the cover beam template to slide towards the inside of the detection platform 1. During the movement of the cap beam template driven by the placement frame 2, the third motor 35 and the heating wire 36 are started by the controller. The third motor 35 drives the fan roller 34 to rotate inside the hot air chamber 33, stirring the airflow and generating wind. This causes the heated air around the heating wire 36 to be blown towards the placement frame 2 and the cap beam template through the air guide 37, thereby heating the cap beam template and cleaning the surface of the cap beam template with air. This not only blows away the dust on the surface of the cap beam template, but also ensures that the temperature of the cap beam template is consistent with the ambient temperature, thereby improving the accuracy of the flatness detection of the laser profiler group 109. As the placement frame 2 and the cover beam template move toward the interior of the testing platform 1, the cover beam template gradually approaches the lifting plate 31 until the bottom of the cover beam template abuts against the lifting plate 31. Since the bottom of the lifting plate 31 is inclined and slidably connected to the fixed frame 3, when the placement frame 2 and the limiting plate 201 push the cover beam template toward the interior of the testing platform 1, the cover beam template gradually lifts the lifting plate 31 until the bottom of the lifting plate 31 is completely located at the top of the cover beam template. Since the air guide 37 is located at the bottom of the lifting plate 31, and the bottom of the lifting plate 31 is inclined, the air guide 37 is opened at an angle. The air heated by the heating wire 36 in the hot air cavity 33 is heated by the fan blade roller 34 and then passes through the air guide 37 to heat the cover beam template passing below in sequence. This improves the overall heating of the cover beam template and further reduces the temperature difference between the cover beam template and the current detection environment. This reduces the thermal expansion and contraction changes caused by temperature changes inside and on the surface of the cover beam template, thereby improving the detection accuracy of the flatness of the laser profiler group 109. Furthermore, when the cap beam template passes the bottom of the lifting plate 31, the controller activates the first electromagnet 41, causing it to become magnetic and repel the magnetic plate 43. This causes the magnetic plate 43 to slide and push the scraper plate 44 inside the outer frame 4 until the scraper plate 44 comes into contact with the top of the cap beam template. As the cap beam template continues to move towards the interior of the detection platform 1, the scraper plate 44 can scrape the top of the cap beam template. (This is in accordance with the instructions attached.) Figure 10 As shown, the scraper 44 is staggered and has filter holes on its surface. Without affecting hot air cleaning and heating, it cleans the rust and other clumps of attached material on the surface of the cap beam template, thereby reducing the impact of these attached materials on the laser profiler group 109 and further improving the detection accuracy of the flatness of the cap beam template. Once the cap beam template enters the testing platform 1, the first motor 104 can be started by the controller. The first motor 104 drives the first lead screw 102 to rotate, and the first lead screw 102 drives the support frame 105 connected to its surface thread to slide inside the adjustment groove 101. Since the surfaces of the two screws 107 are slidably sleeved with horizontal plates, when the support frame 105 on the surface of the first lead screw 102 slides, the support frame 105 drives the screws 107 and the horizontal plate to move synchronously, so that the horizontal plate drives the laser profiler group 109 to move synchronously, and the horizontal plate drives the support frame 105 on the surface of the limit rod 103 to move synchronously. Thus, the laser profiler group 109 can move along the length of the testing platform 1, and in the process of moving, it performs laser scanning and flatness detection on the cap beam template below. It should be noted that all the devices in this invention are controlled by a controller. The cover plate 311 serves to seal the hot air chamber 33 and can be opened when needed to inspect and maintain the equipment inside the hot air chamber 33. The baffle plate 312 serves to seal the air guide 37, ensuring that the number of air guide 37 openings can be adjusted according to the width of the cover beam template, avoiding opening too many air guide 37s, which would cause the hot air to diffuse to both sides, making the hot air blow more concentrated towards the cover beam template, thereby improving the heating efficiency of the cover beam template. The activation of the heating wire 36 depends on the current ambient temperature. If the ambient temperature is higher than that of the cap beam template, the heating wire 36 can be activated, so that the air blown out of the hot air chamber 33 is hot air. The hot air compensates for the temperature difference between the ambient temperature and the cap beam template. If the ambient temperature is lower than that of the cap beam template, the heating wire 36 is not activated, and the third motor 35 and the fan roller 34 are activated directly, so that the air blown out of the hot air chamber 33 is normal temperature air. This plays a role in cooling down the cap beam template, thereby compensating for the temperature difference between the ambient temperature and the cap beam template. To ensure more precise temperature control, a temperature sensor can be installed on the top of the placement rack 2 to more accurately control the cover beam template and detect the temperature difference in the environment. The two ends of the horizontal plate are slidably sleeved on the surfaces of the two screws 107, thereby making the two support frames 105, the horizontal plate and the laser profiler assembly 109 form a whole. When the first lead screw 102 drives the support frame 105 on its surface to move, the support frame 105 on the surface of the limit rod 103 moves synchronously under the drive of the horizontal plate. When it is necessary to adjust the distance between the laser profiler assembly 109 and the cap beam template, the support nuts 108 on the surfaces of the two screws 107 can be rotated to adjust the height of the support nuts 108 on the surfaces of the screws 107. Then, the horizontal plate is placed on top of the support nuts 108 and its height is adjusted along with the support nuts 108, thereby adjusting the distance between the laser profiler assembly 109 and the cap beam template.

[0020] Example 2: A protective frame 5 is fixed to the side of the lifting plate 31 near the detection platform 1. A sponge roller 51 is rotatably connected inside the protective frame 5. A storage groove 6 is opened on the inner wall of both sides of the detection platform 1. A second spring 61 is fixed inside the storage groove 6. A slide rod 62 is slidably connected to the inner wall of both sides of the detection platform 1. One end of the slide rod 62 passes through the second spring 61 and is located in the inner ring of the second spring 61. A clamping plate 63 is fixed to the end of the slide rod 62 near the detection platform 1, and one end of the second spring 61 is fixed to the clamping plate 63. A first connecting piece 64 is fixed to the end of the slide rod 62 away from the detection platform 1. A second electromagnet 65 is fixed to the surface of both sides of the detection platform 1. The second electromagnet 65 corresponds to the first connecting piece 64. Specifically, based on Embodiment 1, when the cap beam template passes the bottom of the lifting plate 31, it is first blown by the hot air in the hot air chamber 33 for preliminary dust removal. Then, the scraper plate 44 scrapes off the clumps and attachments on the surface of the cap beam template. Then, the cap beam template enters the detection platform 1 and passes under the sponge roller 51. Then, the sponge roller 51 wipes off the oil stains on the surface of the cap beam template, and then the cap beam template is cleaned again, which further improves the cleanliness of the surface of the cap beam template and thus improves the accuracy of the laser profiler group 109 in detecting the flatness of the cap beam template. Furthermore, after the second motor 12 drives the second lead screw 13 to transmit the support slider 14 and the placement frame 2 completely retracted into the interior of the testing platform 1, the placement frame 2 drives the cover beam template into the interior of the testing platform 1. At this time, the controller activates the second electromagnet 65, which attracts the first connecting piece 64 after being energized. This causes the first connecting piece 64 to drive the slide rod 62 to slide on both sides of the testing platform 1. The slide rod 62 then drives the clamping plate 63 to move toward both sides of the cover beam template until the two clamping plates 63 clamp the two sides of the cover beam template, thereby limiting the cover beam template and preventing it from shifting during the testing process, thus improving the accuracy of the cover beam template testing. Meanwhile, under the support of the clamping plate 63 by the second spring 61, when the cap beam template is affected by mechanical vibration, part of the vibration is absorbed by the clamping plate 63, the slide rod 62 and the second spring 61, and the pressure of the second spring 61 is released by the friction between the detection platform 1 and the slide rod 62, thereby achieving the effect of shock absorption and improving the accuracy of the flatness detection of the cap beam template.

[0021] Example 3: The placement rack 2 has an internal cavity 21, a ventilation slot 22 on the top of the placement rack 2, and a discharge slot 23 on the bottom of the placement rack 2 near the limiting plate 201. Both the ventilation slot 22 and the discharge slot 23 are connected to the internal cavity 21. An inner support plate 7 is fixed to the top of the horizontal part of the detection platform 1. The inner support plate 7 is slidably connected to the internal cavity 21. The two sides of the inner support plate 7 near the placement rack 2 are slidably connected to the second connecting piece 71. A first filter plate 72 is fixed to one end of the second connecting piece 71. A third spring 73 is fixed to both ends of the first filter plate 72 away from the inner support plate 7. A second filter plate 74 is fixed to one end of the third spring 73. A third electromagnet 75 is fixed to the end of the inner support plate 7 near the third spring 73. The first filter plate 72 and the second filter plate 74 are both slidably connected to the internal cavity 21. Specifically, based on Embodiment 1 and Embodiment 2, when the second motor 12 drives the second lead screw 13 to drive the support slider 14 and the placement frame 2 to move toward the interior of the detection platform 1, that is, when the placement frame 2 drives the cover beam template to move toward the interior of the detection platform 1, when the cover beam template passes under the lifting plate 31, the air in the hot air cavity 33 is heated by the heating wire 36 and blown toward the cover beam template through the air guide 37, and part of the hot air enters the interior of the built-in cavity 21 through the ventilation slot 22; Simultaneously, as the placement frame 2 moves toward the detection platform 1, it is sleeved on the outside of the inner support plate 7 and moves toward the inner support plate 7. This causes the first filter plate 72 and the second filter plate 74 to move inside the built-in cavity 21. When hot air enters the built-in cavity 21 through the ventilation slot 22, the first filter plate 72 and the second filter plate 74 intercept the dust or other debris carried by the hot air, while ensuring that the hot air can circulate inside the built-in cavity 21 and is blown toward the bottom of the cap beam template through the remaining ventilation slots 22. This achieves the purpose of heating the bottom of the cap beam template, thereby improving the overall heating efficiency of the cap beam template and reducing the time for the cap beam template to compensate for the temperature difference. This improves the efficiency and accuracy of the cap beam template detection. When the placement frame 2 moves the cover beam template towards the inner support plate 7, the end of the inner cavity 21 near the limiting plate 201 gradually approaches and contacts the second filter plate 74. Then, the inner wall of the inner cavity 21 near the limiting plate 201 pushes the second filter plate 74 and compresses the third spring 73. Subsequently, the third spring 73, the first filter plate 72, and the second connecting piece 71 are pushed towards the inner support plate 7, so that the second connecting piece 71 retracts into the interior of the inner support plate 7. This ensures that the placement frame 2 moves the cover beam template completely into the interior of the testing platform 1. As the placement rack 2 moves toward the inner support plate 7, the first filter plate 72 and the second filter plate 74 gradually move toward the limiting plate 201 inside the built-in cavity 21 until the discharge chute 23 moves and passes under the first filter plate 72 and the second filter plate 74, thereby allowing the dust and debris intercepted by the first filter plate 72 and the second filter plate 74 to be discharged to the outside through the discharge chute 23.

[0022] It should be noted that when the placement frame 2 moves the cap beam template toward the interior of the testing platform 1, that is, when the placement frame 2 is sleeved on the outside of the inner support plate 7 and moves toward the interior of the testing platform 1, the ventilation slots 22 that enter the testing platform 1 are successively closed by the inner support plate 7, while the ventilation slots 22 located outside the testing platform 1 remain unobstructed. This ensures that the hot air in the inner cavity 21 can be concentrated and blown toward the cap beam template located outside the testing platform 1, which not only improves the wind force of the hot air and the efficiency of heating the cap beam template, but also avoids the hot air being blown back into the interior of the testing platform 1, thereby preventing secondary pollution of the cap beam template by dust.
