[0033] Please refer to Figure 1 and Figure 2An embodiment of the present invention provides a railway T-beam formwork detection system, comprising a T-beam formwork 1, a mounting frame 2, a length detection device, a width detection device and a pre-camber detection device; a horizontally extending T-shaped cavity 11 is formed in the T-beam formwork 1; the mounting frame 2 is arranged above the T-beam formwork 1; the length detection device is used to be arranged in the T-shaped cavity 11 to detect the length of the T-shaped cavity 11; the width detection device is used to be arranged in the T-shaped cavity 11 to detect the width of the T-shaped cavity 11; the pre-camber detection device comprises a detection vehicle 51 and a pre-camber detector, the detection vehicle 51 is arranged on the mounting frame 2, and can reciprocate relative to the mounting frame 2 along the width direction of the T-shaped cavity 11, the pre-camber detector is arranged at the lower end of the detection vehicle 51, and is used to detect the pre-camber of the bottom surface of the T-shaped cavity 11.

[0034] Specifically, the horizontal extension, that is, the length direction of the T-shaped cavity 11 is the horizontal direction, for example, referring to Figure 2 , the horizontal direction can be the X-axis direction as shown in the figure. It should be noted that the T-shaped cavity 11 is adapted to the shape of the railway T-beam to be prefabricated. When the dimensional accuracy of the T-shaped cavity 11 is detected to be qualified, the quality of the railway T-beam cast through the T-shaped cavity 11 can be guaranteed. It should also be noted that after the T-beam formwork 1 is assembled, the length detection device and the width detection device can be installed correspondingly in the T-shaped cavity 11, and then the pre-camber detection device can be installed correspondingly on the mounting frame 2 to detect the T-beam formwork 1. After the detection is completed, the length detection device, the width detection device and the pre-camber detection device can be removed accordingly.

[0035] In this embodiment, the length detection device can be installed in the T-shaped cavity 11 to detect the width of the T-shaped cavity 11, thereby automatically detecting and obtaining the length information of the T-shaped cavity 11; the width detection device can be installed in the T-shaped cavity 11 to detect the width of the T-shaped cavity 11, thereby automatically detecting and obtaining the width information of the T-shaped cavity 11; the pre-camber detection device can be installed on the mounting frame 2 above the T-beam template 1 to detect the bottom surface pre-camber of the T-shaped cavity 11, thereby automatically detecting and obtaining the pre-camber information of the T-shaped cavity 11. In this way, the length information, width information and pre-camber information of the T-shaped cavity 11 can be automatically detected by this system, replacing the manual detection. Manual measurement avoids the large deviation easily produced by manual measurement and causes inaccurate detection results, thereby improving the detection accuracy of the railway T-beam template 1; in addition, by setting the pre-camber detection device as a detection vehicle 51 and a pre-camber detector, and the detection vehicle 51 can move back and forth along the width direction of the T-shaped cavity 11 on the mounting frame 2, so as to drive the pre-camber detector to detect the pre-camber of multiple areas along the width direction of the bottom surface of the T-shaped cavity 11, the pre-camber of multiple places along the width of the bottom surface of the T-shaped cavity 11 can be obtained, and the detection result is more comprehensive, thereby providing more accurate pre-camber information, and further improving the detection accuracy of the railway T-beam template 1.

[0036] Alternatively, see Figure 1 and Figure 2 The T-shaped cavity 11 has a first inner wall 111 and a second inner wall 112 arranged opposite to each other along the length direction; the length detection device includes a first laser ranging sensor 31 and a first reflector 32, the first laser ranging sensor 31 is used to be arranged on the first inner wall 111 of the T-shaped cavity 11, and the first reflector 32 is used to be arranged on the second inner wall 112 of the T-shaped cavity 11 and horizontally opposite to the first laser ranging sensor 31.

[0037] Specifically, the first laser ranging sensor 31 can determine the distance between the first laser ranging sensor 31 and the first reflector 32 by emitting a laser pulse to the first reflector 32 and measuring the time it takes for the laser pulse to be reflected back, thereby obtaining the length of the T-shaped cavity 11 .

[0038] In this embodiment, the length detection device is provided with a first laser ranging sensor 31 and a first reflector 32, so as to detect the length of the T-shaped cavity 11 by means of laser ranging. Laser ranging is not interfered with by the external environment, which is conducive to improving the detection accuracy of the length of the T-shaped cavity 11. In addition, the first reflector 32 can reflect the laser beam emitted by the first laser ranging sensor 31, so that the first laser ranging sensor 31 can receive a stronger echo signal, thereby further improving the detection accuracy of the length of the T-shaped cavity 11.

[0039] Alternatively, see Figure 1 and Figure 2 Four length detection devices are provided, and the first laser ranging sensors 31 of the four length detection devices are respectively located at the four corners of the first inner wall 111 of the T-shaped cavity 11, and the first reflectors 32 of the four length detection devices are respectively located at the four corners of the second inner wall 112 of the T-shaped cavity 11.

[0040] In this embodiment, four length detection devices are used to simultaneously detect the length of the T-shaped cavity 11, so that the length data of the four corners of the T-shaped cavity 11 can be obtained. The detection data is more comprehensive, avoiding the situation where the lengths at different locations are different due to template processing errors, and further improving the detection accuracy of the length of the T-shaped cavity 11.

[0041] Alternatively, see Figure 1 and Figure 2 The T-shaped cavity 11 has a third inner wall 113 and a fourth inner wall 114 arranged opposite to each other along the width direction; the width detection device includes a second laser ranging sensor 41 and a second reflector 42, the second laser ranging sensor 41 is used to be arranged on the third inner wall 113 of the T-shaped cavity 11, and the second reflector 42 is used to be arranged on the fourth inner wall 114 of the T-shaped cavity 11 and horizontally opposite to the second laser ranging sensor 41.

[0042] Specifically, the second laser ranging sensor 41 can determine the distance between the second laser ranging sensor 41 and the second reflector 42 by emitting laser pulses to the second reflector 42 and measuring the time it takes for the laser pulses to be reflected back, thereby obtaining the width of the T-shaped cavity 11 .

[0043] In this embodiment, the width detection device is provided with a second laser ranging sensor 41 and a second reflector 42, so as to detect the length of the T-shaped cavity 11 by means of laser ranging. Laser ranging is not interfered with by the external environment, which is conducive to improving the detection accuracy of the width of the T-shaped cavity 11; and the second reflector 42 can reflect the laser beam emitted by the second laser ranging sensor 41, so that the second laser ranging sensor 41 can receive a stronger echo signal, thereby further improving the detection accuracy of the width of the T-shaped cavity 11.

[0044] Alternatively, see Figure 1 and Figure 2 Three width detection devices are provided, and the second laser ranging sensors 41 of the three width detection devices are all located on the third inner wall 113 of the T-shaped cavity 11, and one of the three second laser ranging sensors 41 is located in the middle of the third inner wall 113 of the T-shaped cavity 11 along the length direction, and the other two are respectively located at both ends of the third inner wall 113 of the T-shaped cavity 11 along the length direction. The second reflectors 42 of the three width detection devices are all located on the fourth inner wall 114 of the T-shaped cavity 11 and are horizontally opposite to the three second laser ranging sensors 41.

[0045] In this embodiment, three width detection devices are used to simultaneously detect the width of the T-shaped cavity 11, so that the width data of the three detection points along the length direction of the T-shaped cavity 11 can be obtained. The detection data is more comprehensive, avoiding the situation where the width at different locations is different due to template processing errors, and further improving the detection accuracy of the width of the T-shaped cavity 11.

[0046] Alternatively, see Figure 1 and Figure 2 A track 21 extending along the width direction of the T-shaped cavity 11 is provided on the lower side of the mounting frame 2 ; a roller 511 rollingly engaged with the track 21 is provided on the inspection vehicle 51 .

[0047] Specifically, the cross-section of the track 21 can be configured as a "T"-shaped structure, comprising a horizontally extending bottom wall, a connecting wall extending upward from the middle of the bottom wall, and two limiting walls extending horizontally from the connecting wall to either side. A rolling groove adapted to the shape of the roller 511 is defined between each limiting wall and the bottom wall. The inspection vehicle 51 is provided with two rollers 511, which are respectively disposed in the two rolling grooves and roll back and forth along the rolling grooves. Specifically, two tracks 21 can be provided, and the two tracks 21 are spaced apart along the length of the T-shaped cavity 11. The inspection vehicle 51 is simultaneously mounted on the two tracks 21 via the rollers 511. It should be noted that the bottom surface of the T-shaped cavity 11 is divided into multiple detection areas distributed in sequence along the width direction of the T-shaped cavity 11. Due to processing errors in the template, the pre-curvature of multiple detection areas may be different. At this time, if the pre-curvature detection device only detects one detection area and regards the detection result as the pre-curvature of each detection area, the final judgment on the template accuracy may not be consistent with the actual situation.

[0048] In this embodiment, a track 21 extending along the width direction of the T-shaped cavity 11 is provided on the mounting frame 2, and a roller 511 is provided on the detection vehicle 51. In this way, when the roller 511 rolls along the track 21, it can drive the detection vehicle 51 to move back and forth along the width direction of the T-shaped cavity 11, so as to facilitate the delivery of the pre-curvature detector to different detection areas, thereby correspondingly detecting the pre-curvature of multiple detection areas on the bottom surface of the T-shaped cavity 11, thereby improving the detection accuracy of the pre-curvature.

[0049] Alternatively, see Figure 1 and Figure 2 The pre-camber detector includes three measuring modules 52 and a calculation module; the three measuring modules 52 are arranged on the detection vehicle 51 and are respectively opposite to the middle and both ends of the bottom surface of the T-shaped cavity 11, and the measuring modules 52 are used to detect the distance between the measuring modules 52 and the bottom surface of the T-shaped cavity 11; the calculation module is electrically connected to the three measuring modules 52, and is used to calculate the distance data detected by the three measuring modules 52 to obtain the pre-camber of the bottom surface of the T-shaped cavity 11.

[0050] Specifically, the calculation module can calculate the pre-camber of the corresponding inspection area based on the distance data detected by the three measurement modules 52. For example, let the distance measured by the central measurement module 52 be d1, and the distances measured by the two end measurement modules 52 be d2 and d3 respectively, then the pre-camber h = (d2 + d3) / 2 - d1. Specifically, the inspection vehicle 51 can include a vehicle beam extending along the length of the T-shaped cavity 11, and the three measurement modules 52 are disposed on the vehicle beam.

[0051] In this embodiment, the pre-camber of the corresponding detection area on the bottom surface of the T-shaped cavity 11 can be automatically detected and calculated by the measuring module 52 and the calculating module, thereby avoiding manual measurement and calculation and further improving the detection accuracy.

[0052] Alternatively, see Figure 1 The railway T-beam formwork detection system also includes a control device 6, which is electrically connected to the length detection device, the width detection device and the pre-camber detection device, and is used to receive the length information detected by the length detection device, the width information detected by the width detection device and the pre-camber information detected by the pre-camber detection device.

[0053] For details, please refer to Figure 1 The railway T-beam formwork detection system may further include a computer 7 connected to the control device 6. The detection information obtained by the control device 6 may be transmitted to the computer 7. A three-dimensional model of a prefabricated component is generated by the computer 7 software, and the three-dimensional model of the prefabricated component is compared with the three-dimensional model of the component preset in the computer 7 software to determine whether the T-beam formwork 1 is qualified.

[0054] The embodiment of the present invention also provides a railway T-beam template detection method, based on the railway T-beam template detection system as described above, please refer to Figure 1 and Figure 2 , the railway T-beam template detection method includes:

[0055] Control the length detection device, the width detection device and the pre-camber detection device to detect the T-beam template 1 respectively;

[0056] The control device 6 obtains the length information detected by the length detection device, the width information detected by the width detection device, and the pre-camber information detected by the pre-camber detection device;

[0057] generating a three-dimensional model of the prefabricated component according to the length information, the width information and the pre-camber information;

[0058] The prefabricated component three-dimensional model is compared with a preset component three-dimensional model, and whether the T-beam template 1 is qualified is determined based on the comparison result.

[0059] It should be noted that the above-mentioned "generating a three-dimensional model of the prefabricated component based on the length information, the width information and the pre-camber information" can be performed in the computer 7, for example, using the finite element analysis software of the computer 7 to generate the three-dimensional model of the prefabricated component.

[0060] In this embodiment, the railway T-beam template detection method first detects the T-beam template 1, then obtains the detection information through the control device 6, and then generates a three-dimensional model of the prefabricated component. Finally, it compares it with the preset three-dimensional model of the component to determine whether the T-beam template 1 is qualified, that is, it realizes automatic detection, automatic transmission and automatic result judgment of the T-beam template 1, avoids a large amount of manual participation, and improves the detection accuracy and detection efficiency of the T-beam template 1.

[0061] Optionally, after comparing the prefabricated component three-dimensional model with a preset component three-dimensional model and determining whether the T-beam template 1 is qualified according to the comparison result, the method further includes:

[0062] If the T-beam template 1 is determined to be qualified, the installation state of the T-beam template 1 is kept unchanged;

[0063] If the T-beam formwork 1 is determined to be unqualified, the installation state of the T-beam formwork 1 is adjusted.

[0064] It should be noted that the standard for judging whether the T-beam template 1 is qualified is determined according to the error requirements. When the difference between the prefabricated component three-dimensional model and the preset component three-dimensional model regarding a certain size parameter is not within the required error range, the T-beam template 1 is judged to be unqualified.

[0065] In this embodiment, the installation status of the T-beam template 1 is adjusted according to the qualification of the T-beam template 1 to ensure that the final installation status of the T-beam template 1 meets the requirements, thereby avoiding the quality of the T-beam due to unqualified installation of the T-beam template 1.

[0066] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
