[0029] like Figure 1 As shown, the present invention provides a steel-concrete composite beam segment quality acceptance detection system, comprising:

[0030] The bearing platform 1 is fixed on the ground at the acceptance site and has a horizontal upper surface. A placement area for the steel-concrete composite beam is provided in the middle of the bearing platform 1. The placement area matches the bottom shape and size of the steel-concrete composite beam. Limiting blocks 2 are provided on the outer sides of the four top corners of the placement area on the bearing platform 1, and bases 3 are provided on the outer sides of the four top corners of the bearing platform 1.

[0031] The first distance measuring system is installed on the bearing platform 1, and includes a plurality of rows of web distance measuring sensors 4 and a plurality of rows of top plate distance measuring sensors 5 arranged at intervals along the length direction outside the placement area. The top plate distance measuring sensors 5 are located outside the web distance measuring sensors 4. The top plate distance measuring sensors 5 are used to measure the distance to the corresponding position of the bottom of the top plate of the placed steel-concrete composite beam upwards, and the web distance measuring sensors 4 are used to measure the distance to the corresponding position of the outer side of the web of the placed steel-concrete composite beam;

[0032] The second distance measuring system is installed on the base 3, and includes at least four groups of edge distance measuring sensors 6, each group includes two edge distance measuring sensors 6 which are arranged relatively along the length direction or width direction of the bearing platform 1 and are located within the top plate height range of the steel-concrete composite beam to be measured, wherein two groups of edge distance measuring sensors 6 are respectively aligned with the two top plate distance measuring sensors 5 at the outermost ends of the same side of the two rows of top plate distance measuring sensors 5, and are used to detect the top plate width of the corresponding position of the steel-concrete composite beam, and the other two groups of edge distance measuring sensors 6 are located outside the two ends of the length direction of the steel-concrete composite beam to be measured, and are used to detect the top plate length of the corresponding position of the steel-concrete composite beam;

[0033] The reference system includes a reference target 7, a target to be measured 8 and a visual camera 9. The reference target 7 and the visual camera 9 are respectively mounted on the base 3 and arranged relatively to each other. The target to be measured 8 is mounted at the position of each edge distance sensor 6. The visual camera 9 is used to obtain the position of the target to be measured 8 relative to the reference target 7, so as to calibrate the position of the edge distance sensor 6.

[0034] The visual inspection system includes a track 10 arranged around the outer side of the carrying platform 1, a traveling trolley 11 is arranged on the track 10, a driving motor for driving the traveling trolley 11 to move is arranged on the traveling trolley 11, and a camera 12 is arranged on the side of the traveling trolley 11 facing the carrying platform 1, and the camera 12 is used to obtain the appearance image of the steel-concrete composite beam;

[0035] The remote control terminal is respectively connected to all the web distance measuring sensors 4, the top plate distance measuring sensors 5, the edge distance measuring sensors 6, the visual camera 9, the camera 12, and the drive motor for communication, and is used to obtain and display the data sent by all the communication connection devices, and is also used to control the operation of all the communication connection devices.

[0036] For the convenience of explanation, Figure 1 The left and right directions are the length directions of the steel-concrete composite beam. Figure 1 The up and down direction is the width direction of the steel-concrete composite beam. A bearing platform 1 is set as the acceptance operation area. The bearing platform 1 ensures a regular surface and good bearing capacity. The placement area is consistent with the structure of the steel-concrete composite beam and is generally rectangular. An L-shaped limit block 2 is set on the bearing platform 1. The inner corners of the limit blocks 2 on the four sides are aligned with the bottom size range of the steel-concrete composite beam segment. The base 3 is adjacent to the outer side of the bearing platform 1 and can be integrated with the bearing platform 1 or detachably fixed. The base 3 is generally arranged corresponding to the four top corners of the placement area. The reference target 7 and the visual camera 9 are first installed, and the reference target 7 is used as a reference point. Then, after the first distance measurement system is installed on the bearing platform 1, the installation position information of each plate distance measurement sensor and the top plate distance measurement sensor 5 is determined by the upper surface of the bearing platform 1. The type, quantity and position of the added sensors on the bearing platform 1 can be designed by yourself according to the requirements of the detection project. The principle will not be repeated here.

[0037] Through the first distance measuring system, top plate distance measuring sensors 5 and web distance measuring sensors 4 are arranged in a horizontal arrangement along the placement area. According to the detection requirements, multiple rows of top plate distance measuring sensors 5 and web distance measuring sensors 4 can be set to characterize the deformation of the corresponding positions of the steel-concrete composite beam in a larger range and more accurately. After obtaining the distance data, it is sent to the remote control terminal for display. At the same time, the data of a row of top plate distance measuring sensors 5 or web distance measuring sensors 4 are fitted to form a surface line shape, which is compared with the straight line, and a deformation threshold is set. The concave and convex positions that exceed the deformation threshold can be considered as the positions where the steel-concrete composite beam has deformation. For the points that do not exceed the deformation threshold, a connecting line of the position can be formed to judge the horizontality.

[0038] The second distance measuring system measures and feedbacks the distance of the position near the end of the top plate of the steel-concrete composite beam respectively. On the one hand, after setting a sufficient number of groups, the parallel lines of the corresponding side of the top plate of the steel-concrete composite beam can be obtained. On the other hand, the width or length of the corresponding position of the top plate of the steel-concrete composite beam can be obtained by subtracting the measured distance data according to the position difference of the relatively set edge line distance measuring sensors 6 themselves. The number of groups of edge line distance measuring sensors 6 in the length direction or width direction of the bearing platform 1 can be set according to needs.

[0039] The track 10 is arranged on the outside of the base 3, and the driving motor drives the trolley 11 to move along the track 10. During the movement, the camera 12 takes pictures of the steel-concrete composite beam. The camera 12 can adjust its direction on the trolley 11 to change the distance from different positions of the steel-concrete composite beam, so as to clearly capture the surface or weld position of the steel-concrete composite beam.

[0040] All data are acquired, summarized and displayed visually on the remote control terminal, and a basic line graph is drawn based on the acquired data. The more single-row web distance sensors 4 or top plate distance sensors 5 there are, the more accurate the linear state simulation is. The size, line shape and other data of the steel-concrete composite beam recorded before leaving the factory are used as the basic data for comparison.

[0041] The steel-concrete composite beam segment quality acceptance detection system of the present invention comprises a bearing platform 1, a first distance measuring system, a second distance measuring system, a reference system, a visual detection system, and a remote control terminal. The bearing platform 1 is installed on the acceptance site, a limit block 2 is arranged on the bearing platform 1, and a base 3 and a track 10 are arranged outward from the outside of the bearing platform 1 in sequence, and a precise placement area of ​​the steel-concrete composite beam is formed inside the limit block 2. The first distance measuring system is arranged on the bearing platform 1 to obtain the deformation of the top plate and the bottom plate of the steel-concrete composite beam along the length direction. The second distance measuring system and the reference system are respectively installed on the base 3 for the steel-concrete composite beam. The position, line shape and size status of the edge of the top plate. The reference system is used to compare the reference target 7 to determine the accurate relative positions of the first distance measuring system and the second distance measuring system on the bearing platform 1, so as to obtain the current contour status of the steel-concrete composite beam. The visual inspection system is used to complete the visual inspection items of the steel-concrete composite beam along the track 10. All data are displayed and analyzed on the remote control terminal. It has the function of comprehensively obtaining the acceptance project data of various steel-concrete composite beams, and can judge whether the steel-concrete composite beams are deformed or have defects after transportation more quickly and accurately, which greatly improves the quality acceptance efficiency of steel-concrete composite beams.

[0042] In another technical solution, Figure 1As shown, the whole supporting platform 1 is a rectangular structure, and the base 3 is symmetrically arranged outside the four corners of the supporting platform 1, and the outer side of the length side range of the supporting platform 1 is used as the alignment installation surface of the track 10. The base 3 is arranged to facilitate the installation of the second distance measurement system and the reference system, and serves as a positioning guide structure surrounded by the track 10 on the outside.

[0043] In another technical solution, Figure 1 As shown, the track 10 includes two parallel straight tracks 13 and semicircular tracks 14 respectively connected between the same ends of the two straight tracks 13, wherein the straight tracks 13 are arranged close to the outer side of the corresponding side of the base 3. In combination with the length and width of the steel-concrete composite beam, the circular track 10 is arranged, and the oblong combination mode occupies less space.

[0044] In another technical solution, Figure 1 As shown, the web distance sensor 4 and the top plate distance sensor 5 are laser distance sensors, and the side line distance sensor 6 is an infrared distance sensor. The use of laser distance sensors to measure linear changes is more accurate, and the use of infrared distance sensors on the sides of steel-concrete composite beams is conducive to reducing installation costs.

[0045] In another technical solution, Figure 1 As shown, the web distance measuring sensor 4 and the top plate distance measuring sensor 5 are cross-arranged in the length direction of the carrying platform 1 to expand the detection position range.

[0046] In another technical solution, Figure 1 As shown, an electric telescopic mechanism is connected between the walking trolley 11 and the camera 12, and the remote control terminal is connected to the driving end of the electric telescopic mechanism in communication, and is used to control the electric telescopic mechanism to drive the camera 12 to a desired height. By setting the electric telescopic mechanism, the height and direction of the camera 12 can be adjusted on the remote control terminal to better obtain the appearance state image of the steel-concrete composite beam.

[0047] The present invention also provides a steel-concrete composite beam segment quality acceptance detection method, comprising the following steps:

[0048] S1. After the steel-concrete composite beam is manufactured, the initial structural model of the steel-concrete composite beam is obtained by scanning, and the size and linear information are extracted and stored in the remote control terminal as basic data;

[0049] S2. Arrange the steel-concrete composite beam segment quality acceptance inspection system at the acceptance site, set the placement area and the limit block 2 on the bearing platform 1 according to the initial structure model, scan the positions of the reference target 7 and the target to be measured 8 by the visual camera 9, set the welding quality evaluation standard in the remote control terminal, record the installation position of the first distance measuring system, take the reference target 7 as a reference point, and record the position of the second distance measuring system;

[0050] S3, after the steel-concrete composite beam is transported to the site, it is hoisted and moved to the inner side of all the limit blocks 2 on the bearing platform 1. If it cannot be put in, it is judged that the acceptance fails;

[0051] S4. After the steel-concrete composite beam is successfully placed inside the limit block 2, the remote control terminal receives the distance data of the corresponding position of the steel-concrete composite beam obtained from the first distance measuring system, and the width and length data of the corresponding position of the steel-concrete composite beam obtained from the second distance measuring system. The installation position of the first distance measuring system, the installation position of the second distance measuring system and the distance data, width and length data are fitted in the remote control terminal to obtain the linear state of the current top plate and web plate of the steel-concrete composite beam at the corresponding position and the position state of the top plate edge line. The walking trolley 11 is turned on to drive the camera 12 to move along the track 10 and shoot the welding position of the steel-concrete composite beam, and the shot images are numbered and sent to the remote control terminal;

[0052] S5. On the remote control terminal, compare the current linear state with the size and linear information of the initial structural model to determine whether the steel-concrete composite beam is deformed, determine whether the welding part meets the welding quality evaluation standard based on the captured image, give an acceptance conclusion, complete the steel-concrete composite beam segment quality acceptance, and then lift and remove the current steel-concrete composite beam from the bearing platform 1.

[0053] The reference system determines the accurate positions of the first distance measuring system and the second distance measuring system relative to the bearing platform 1, obtains distance data through the position information of the second distance measuring system itself, and combines the signal fed back from the top plate of the steel-concrete composite beam to obtain the linear direction of the corresponding side of the steel-concrete composite beam, thereby obtaining the outer edge line of each lateral direction of the top plate of the steel-concrete composite beam, and obtaining the relative position of the steel-concrete composite beam in the horizontal plane, thereby obtaining the contour line of the steel-concrete composite beam. After determining the contour position of the steel-concrete composite beam in the placement area, the distance measuring data obtained by the first distance measuring system are combined with the corresponding positions in the placement area one by one, thereby obtaining the steel-concrete composite beam. The linear shape of the beam in the corresponding length direction can be used to determine whether there are any concave-convex changes caused by deformation; the captured images can be manually observed in front of a remote control terminal such as a computer, or a simple algorithm can be set up as needed to capture the welding or surface morphology structure for comparison. All data are displayed and analyzed on the remote control terminal, which has the function of comprehensively obtaining the acceptance project data of various steel-concrete composite beams. It can determine more quickly and accurately whether the steel-concrete composite beams are deformed or have defects after transportation, greatly improving the quality acceptance efficiency of the steel-concrete composite beams, and can carry out continuous inspection in the form of an assembly line.

For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
