Description

Technical Field

[0001] The present application relates to the technical field of crack detection, and in particular to a construction engineering crack detection device. Background Art

[0002] With the continuous expansion of the scale of construction projects and the improvement of building quality requirements, the quality inspection of structural parts such as window openings has gradually become an important part of building quality control. Especially during the casting process of window openings, cracks may occur due to improper construction, material defects and other factors. Window hole cracks not only affect the appearance of the building, but also may affect the stability, water permeability resistance and thermal insulation and sound insulation of the structure. The traditional crack detection method is to scan one by one with a handheld infrared camera, which has several limitations: First, the handheld scanning method can often only detect a single window hole surface, that is, each detection can only cover a certain side of a window hole, and usually the side facing away from the water, because the side facing away from the water is the outer wall, and it becomes more difficult to check the cracks on the outside of the window hole. Operators often cannot accurately aim the camera at the outside of the window hole to shoot, which will lead to missed detections. At the same time, only one surface of cracks is detected each time, and the overall distribution of prefabricated cracks cannot be fully understood, which may make the subsequent repair plan unsuitable. At the same time, there are also situations where the operation efficiency is low and human errors are prone to occur. Summary of the invention

[0003] In order to improve the efficiency and accuracy of window opening crack detection, especially to be able to detect cracks inside and outside the window opening in all directions and at multiple angles, the present application provides a construction engineering crack detection device.

[0004] The present application provides a construction engineering crack detection device that adopts the following technical solution: A construction engineering crack detection device comprises a bearing seat and a control panel, the bearing seat is provided with a driving wheel group, the driving wheel group can drive the bearing seat to move laterally and forward and backward, a telescopic component is provided on the bearing seat, the telescopic component is connected with a rotating component, the rotating component is connected with a swinging component, a first mounting plate is provided on the rotating component, a second mounting plate is provided on the swinging component, a first infrared camera is provided on the first mounting plate, and a second infrared camera is provided on the second mounting plate; The first mounting plate and the first infrared camera face the back-to-water side of the window opening; the swing assembly is used to drive the second mounting plate to be in a horizontal state or a vertical state; when the second mounting plate is in a horizontal state, the second infrared camera faces the inner wall of the window opening; when the second mounting plate is in a vertical state, the second infrared camera faces the front-to-water side of the window opening; the control panel is used to control the start-up of the driving wheel group, the telescopic assembly, the rotating assembly and the swing assembly; and the images of the first infrared camera and the second infrared camera are synchronously uploaded to the control panel, and the control panel can take screenshots of the images and save them.

[0005] By adopting the above technical solution, the present invention uses two infrared cameras, one aimed at the back surface of the window hole, and the other aimed at the inner wall or the front surface of the window hole. Through the relative position of the two cameras, it is possible to achieve synchronous detection of cracks inside and outside the window hole and at different angles, greatly improving the comprehensiveness and accuracy of crack detection. This two-way detection method can obtain crack information on different surfaces at the same time, providing more complete data support for subsequent analysis; Unlike traditional handheld scanning methods, the control panel allows the bearing to move freely, and is equipped with telescopic components, rotating components and swing components to flexibly adjust the detection angle. In this way, the second infrared camera can automatically extend out of the window to scan multiple surfaces of the window hole without manual intervention, thereby improving the efficiency and accuracy of the detection.

When the first-level telescopic frame is raised or lowered, the linkage drives the second-level telescopic frame to extend out of the first-level telescopic frame, and drives the third-level telescopic frame to extend out of the second-level telescopic frame. The rotating assembly is fixed on the third-level telescopic frame.

[0007] By adopting the above technical solution, the multi-stage telescopic frame adopts a nested design, so that the entire telescopic assembly occupies very little space in the initial state, which is convenient for walking on the construction site. When measurement is required, the telescopic frame can be extended step by step, providing a larger telescopic range and achieving a larger vertical detection height.

[0008] Optionally, the driving component includes a first motor, the first motor is mounted on the automatic walking vehicle, the first motor is connected to a first screw, and the first screw is threadedly connected to the first-level telescopic frame.

[0010] By adopting the above technical solution, when the first-level telescopic frame rises, the first-level rack drives the first-level gear to rotate, and the first-level gear drives the third-level rack to rise, so that the second-level telescopic frame rises and extends out of the first-level telescopic frame, and because there is a relative displacement between the second-level telescopic frame and the first-level telescopic frame, the second-level rack drives the second-level gear to rotate, and the second-level gear drives the fourth-level rack to rise, so that the third-level telescopic frame extends out of the second-level telescopic frame, thereby realizing the synchronous extension of the first-level telescopic frame, the second-level telescopic frame and the third-level telescopic frame.

[0013] By adopting the above technical solution, the third motor drives the second lead screw to rotate, so that the guide block can move along the guide seat, and the guide seat drives the first gear, the second gear, the adjusting rack and the swing arm to move synchronously when moving. When the swing arm moves from the horizontal section slide rail to the inclined section slide rail, the second mounting plate has extended out of the window. When the swing arm moves on the inclined section slide rail, the swing arm drives the second gear to rotate, the second gear drives the adjusting rack to rotate, and the adjusting rack drives the first gear to rotate, so that the second mounting plate flips to a vertical state. At this time, the second infrared camera faces the water-facing surface of the window opening. By controlling the telescopic assembly, the rotating assembly and the driving wheel group, the second infrared camera and the first infrared camera can be moved along the contour of the window opening and take pictures.

[0014] When it is necessary to photograph the inner wall of the window opening, it is only necessary to start the second motor so that the guide block drives the swing arm to move back to the horizontal section slide rail.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-5 This application is described in further detail.

[0030] The embodiment of the present application discloses a construction engineering crack detection device.

[0031] like Figure 1 The construction engineering crack detection device includes a bearing seat 1 and a control panel 2. A driving wheel group 3 is installed at the bottom of the bearing seat 1. The driving wheel group 3 can drive the bearing seat 1 to move horizontally and forward and backward. A telescopic component 4 is installed on the top of the bearing seat 1. The telescopic component 4 is located at one end of the bearing seat 1. A rotating component 5 is connected to the top of the telescopic component 4. The rotating component 5 is connected to the swing component 6. A first mounting plate 71 is installed on the rotating component 5. A second mounting plate 72 is installed on the swing component 6. A first infrared camera 73 is arranged on the first mounting plate 71. A second infrared camera 74 is arranged on the second mounting plate 72. A counterweight block 11 is also installed on the top surface of the bearing seat 1. A mounting groove 111 is opened on the counterweight block 11. The control part can be placed in the mounting groove 111; The rotating assembly 5 is used to drive the first mounting plate 71, the swinging assembly 6 and the second mounting plate 72 to rotate. The first mounting plate 71 and the first infrared camera 73 face the side of the window opening facing away from the water. The swinging assembly 6 is used to drive the second mounting plate 72 to be in a horizontal state or a vertical state. When the second mounting plate 72 is in a horizontal state, the second infrared camera 74 faces the inner wall of the window opening, and the optical axis of the first infrared camera 73 intersects with the optical axis of the second infrared camera 74 at the same point. When the second mounting plate 72 is in a vertical state, the second infrared camera 74 faces the water-facing side of the window opening, and the optical axis of the first infrared camera 73 coincides with the optical axis of the second infrared camera 74. The control panel 2 is used to operate and control the movement of the driving wheel group 3, the telescopic assembly 4, the rotating assembly 5 and the swinging assembly 6, and the images of the first infrared camera 73 and the second infrared camera 74 are synchronously uploaded to the control panel 2, and the control panel 2 can take screenshots of the images and save them.

[0032] The driving wheel assembly 3 drives the bearing seat 1 to approach the window opening, and at the same time, the telescopic assembly 4 drives the rotating assembly 5, the swinging assembly 6, the first mounting plate 71 and the second mounting plate 72 to rise, so that the first infrared camera 73 faces the bottom of the side of the window opening that is not exposed to the water, and the second infrared camera 74 faces the inner bottom wall of the window opening, and then the driving wheel assembly 3 drives the bearing seat 1 to move along the length direction of the opening to achieve the first detection of the bottom of the window opening. When the bearing seat 1 is located at one side of the window opening, the rotating assembly 5 drives the swinging assembly 6, the first mounting plate 71 and the second mounting plate 72 to rotate, so that the first infrared camera 73 faces the side of the window opening that is not exposed to the water, and the second infrared camera 74 faces the inner wall of the window opening, and then the telescopic assembly 4 drives the first infrared camera 73 and the second infrared camera 74 to rise, so as to achieve the detection of one side of the window opening. According to the above method, the telescopic assembly 4, the driving wheel assembly 3 and the rotating assembly 5 are controlled to move in coordination, so that crack detection can be performed on the top of the window opening and the other side of the surface and inner wall of the window opening.

[0033] After the first round of inspection is completed, the swing assembly 6 drives the second mounting plate 72 to extend out of the window hole and flips the second mounting plate 72 to a vertical state, and then controls the telescopic assembly 4, the driving wheel group 3 and the rotating assembly 5 to move in coordination, so that the back water surface and the opposite side of the front water surface of the window hole can be inspected synchronously.

[0034] The present invention uses two infrared cameras, one aimed at the back surface of the window hole, and the other aimed at the inner wall or the front surface of the window hole. Through the relative position of the two cameras, it is possible to achieve synchronous detection of cracks inside and outside the window hole and at different angles, greatly improving the comprehensiveness and accuracy of crack detection. This two-way detection method can obtain crack information on different surfaces at the same time, providing more complete data support for subsequent analysis; Different from the traditional hand-held scanning method, the control panel 2 is used to control the support 1 to move freely, and the telescopic component 4, the rotating component 5 and the swing component 6 are equipped to flexibly adjust the detection angle. In this way, the second infrared camera 74 can automatically extend out of the window to scan multiple surfaces of the window hole without manual intervention, thereby improving the efficiency and accuracy of the detection. Moreover, the operator only needs to perform simple operations through the remote control to complete the full-scale detection of multiple window holes and their surrounding areas.

[0035] like Figure 2 and Figure 3 The telescopic assembly 4 includes a fixed frame 41, which is bolted to the bearing seat 1. A first-level telescopic frame 42 is sleeved in the fixed frame 41, a second-level telescopic frame 43 is sleeved in the first-level telescopic frame 42, and a third-level telescopic frame 44 is sleeved in the second-level telescopic frame 43. The fixed frame 41, the first-level telescopic frame 42, the second-level telescopic frame 43 and the third-level telescopic frame 44 are all connected by a linkage 8. A driving member 9 for driving the first-level telescopic frame 42 to rise and fall is provided on the bearing seat 1. When the first-level telescopic frame 42 is lifted or lowered, the linkage 8 drives the second-level telescopic frame 43 to extend out of the first-level telescopic frame 42, and drives the third-level telescopic frame 44 to extend out of the second-level telescopic frame 43. The rotating assembly 5 is fixed on the third-level telescopic frame 44.

[0036] The driving member 9 includes a first motor 91, which is mounted on the fixing frame 41 and is built into the bearing seat 1. The first motor 91 is connected to a first lead screw 92, which is threadedly connected to the primary telescopic frame 42. The linkage 8 includes two primary racks 81, two secondary racks 82, two tertiary racks 83 and two quaternary racks 84. The two primary racks 81 are respectively fixed on the two inner side walls of the fixed frame 41, and the two primary racks 81 are staggered. The two secondary racks 82 are arranged on the two inner side walls of the primary telescopic frame 42, and the two secondary racks 82 are staggered. The two tertiary racks 83 are arranged on the two outer side walls of the secondary telescopic frame 43, and the two tertiary racks 83 are staggered. The primary racks 81 and the tertiary racks 83 on the same side are arranged opposite to each other. The two quaternary racks 84 are arranged on the two outer side walls of the tertiary telescopic frame 44, and the two quaternary racks 84 are staggered. The secondary racks 82 and the quaternary racks 84 on the same side are arranged opposite to each other. The first-stage telescopic frame 42 is rotatably connected to the two sides with a first-stage gear 85, which is simultaneously meshed with the first-stage rack 81 and the third-stage rack 83 on the same side. The second-stage telescopic frame 43 is rotatably connected to the two sides with a second-stage gear 86, which is simultaneously meshed with the second-stage rack 82 and the fourth-stage rack 84 on the same side.

[0037] When the first-stage telescopic frame 42 rises, the first-stage rack 81 drives the first-stage gear 85 to rotate, and the first-stage gear 85 drives the tertiary rack 83 to rise, so that the second-stage telescopic frame 43 rises and extends out of the first-stage telescopic frame 42, and because there is a relative displacement between the second-stage telescopic frame 43 and the first-stage telescopic frame 42, the second-stage rack 82 drives the second-stage gear 86 to rotate, and the second-stage gear 86 drives the fourth-stage rack 84 to rise, so that the third-stage telescopic frame 44 extends out of the second-stage telescopic frame 43, and the first-stage telescopic frame 42, the second-stage telescopic frame 43 and the third-stage telescopic frame 44 are extended synchronously.

[0038] The multi-stage telescopic frame is designed in a nested manner, so that the entire telescopic assembly 4 takes up very little space in the initial state, which is convenient for walking on the construction site. When measurement is required, the telescopic frame can be extended step by step, providing a larger telescopic range and achieving a larger vertical detection height.

[0039] like Figure 1 and Figure 4 The rotating assembly 5 includes a second motor 51, the second motor 51 is connected to a rotating plate 52, the rotating plate 52 extends along the length direction of the supporting seat 1 and extends out of the supporting seat 1, the first mounting plate 71 and the swinging assembly 6 are both installed on the part of the rotating plate 52 extending out of the supporting seat 1, the first mounting plate 71 is closer to the second motor 51 than the swinging assembly 6, and the first mounting plate 71 and the second mounting plate 72 are both perpendicular to the rotating plate 52.

[0040] The swing assembly 6 includes a third motor 61 and a guide seat 62, both of which are mounted on the rotating plate 52. The guide seat 62 is provided with two guide rods 63 along its length direction, and the two guide rods 63 pass through the guide block 621. The guide seat 62 is rotatably connected to a second lead screw 64, which is coaxially connected to the third motor 61. The second lead screw 64 is threadedly connected to the guide block 621, and the guide block 621 is rotatably connected to the second mounting plate 72. The central axis of the rotation axis of the second mounting plate 72 and the guide block 621 is perpendicular to the second lead screw 64. The second mounting plate 72 and one end of the rotation axis of the guide block 621 are coaxially fixed with a first gear 65. The guide block 621 A sliding seat 66 is connected to the bottom, and an adjusting rack 67 is slidably connected to the sliding seat 66. The guide block 621 is also rotatably connected to the second gear 68. The first gear 65 and the second gear 68 are both engaged with the adjusting rack 67. A horizontal section slide rail 69 is provided on one side of the guide seat 62. The end of the horizontal section slide rail 69 away from the third motor 61 is connected to the inclined section slide rail 610. The length direction of the horizontal section slide rail 69 is parallel to the length direction of the second lead screw 64. The second gear 68 is coaxially connected to a swing arm 611. The end of the swing arm 611 away from the second gear 68 is rotatably connected to a guide wheel 612. The guide wheel 612 rolls along the horizontal section slide rail 69 and the inclined section slide rail 610.

[0041] The third motor 61 drives the second lead screw 64 to rotate, so that the guide block 621 can move along the guide seat 62. When the guide seat 62 moves, it drives the first gear 65, the second gear 68, the adjusting rack 67 and the swing arm 611 to move synchronously. When the guide wheel 612 moves from the horizontal section slide rail 69 to the inclined section slide rail 610, the second mounting plate 72 has extended out of the window. When the guide wheel 612 moves on the inclined section slide rail 610, the swing arm 611 drives the second gear 68 to rotate, the second gear 68 drives the adjusting rack 67 to move, and the adjusting rack 67 drives the first gear 65 to rotate, so that the second mounting plate 72 is flipped to a vertical state. At this time, the second infrared camera 74 faces the water-facing surface of the window opening. By controlling the telescopic component 4, the rotating component 5 and the driving wheel group 3, the second infrared camera 74 and the first infrared camera 73 can be moved along the contour of the window opening and take pictures.

[0042] When it is necessary to photograph the inner wall of the window opening, it is only necessary to start the second motor 51 so that the guide block 621 drives the swing arm 611 to move back to the horizontal section slide rail 69. At this time, the second mounting plate 72 is in a horizontal state, and the second infrared camera 74 scans the inner wall of the window opening.

[0043] like Figure 1 and Figure 5 The driving wheel group 3 includes a first driving wheel 31, which is located at the four corners of the bearing seat 1. The rotation axis of the first driving wheel 31 is parallel to the width direction of the bearing seat 1. A second driving wheel 32 is arranged between two adjacent first driving wheels 31, and the rotation axis of the second driving wheel 32 is parallel to the length direction of the bearing seat 1. The first driving wheel 31 and the second driving wheel 32 are driven by separate driving motors. The first driving wheel 31 is used to drive the bearing seat 1 to move forward and backward, and the second driving wheel 32 is used to drive the bearing seat 1 to move left and right. A first retractable member 33 for controlling the first driving wheel 31 to leave the ground and a second retractable member 34 for controlling the second driving wheel 32 to leave the ground are arranged in the bearing seat 1. The first driving wheel 31 corresponds to the first retractable member 33 one by one and is rotatably connected, and the second driving wheel 32 corresponds to the second retractable member 34 one by one and is rotatably connected.

[0044] The first contraction member 33 and the second contraction member 34 have the same structure. The first contraction member 33 includes a servo motor 35. The servo motor 35 is connected to an adjusting screw 36. The adjusting screw 36 is threadedly connected to an adjusting sleeve 37. The servo motor 35, the adjusting screw 36 and the adjusting sleeve 37 are all located in the bearing seat 1. One end of the adjusting sleeve 37 extends out of the bottom of the bearing seat 1. The adjusting sleeve 37 is slidably connected to the bearing seat 1, and the bottom of the adjusting sleeve 37 is rotationally connected to the first driving wheel 31.

[0045] The first driving wheel 31 is responsible for forward and backward movement, and the second driving wheel 32 is responsible for left and right movement. This design with clear division of labor enables the entire supporting base 1 to achieve all-round free movement on a two-dimensional plane.

[0046] When the first driving wheel 31 moves, the corresponding servo motor 35 is started to move the corresponding adjusting sleeve 37 in the direction of extending into the supporting seat 1, thereby driving the second driving wheel 32 off the ground to prevent the second driving wheel 32 from rubbing against the ground and causing wear. Conversely, when the second driving wheel 32 moves, the corresponding servo motor 35 is started to move the corresponding adjusting sleeve 37 in the direction of extending into the supporting seat 1, thereby driving the first driving wheel 31 off the ground.

[0047] like Figure 1 and Figure 5 The support base 1 is equipped with a power module 12, a drive control module 13 and an image and video output module 14. The power module 12 provides power for the driving wheel group 3, the telescopic component 4, the rotating component 5 and the swinging component 6. The drive control module 13 is used for the movement position of the telescopic component 4, the rotating component 5 and the swinging component 6. The control panel 2 is built with an image processing and storage module 21, a wireless communication module 22 and an interface and user interaction module 23. The image and video output module 14 transmits the images taken by the first infrared camera 73 and the second infrared camera 74 to the control panel 2. The image processing and storage module 21 is used to process and store images from the camera and save screenshots.

[0048] The implementation principle of the embodiment of the present application is as follows: the telescopic component 4, the rotating component 5 and the swinging component 6 cooperate to drive the first mounting plate 71 and the second mounting plate 72 to move, so that when the first infrared camera 73 is shooting the back surface of the window hole, the second infrared camera 74 can shoot the inner wall or the front surface of the window hole. Through the relative position of the two cameras, the cracks inside and outside the window hole and at different angles can be synchronously detected, which greatly improves the comprehensiveness and accuracy of crack detection. This two-way detection method can obtain crack information on different surfaces at the same time, providing more complete data support for subsequent analysis.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
