Description

Technical Field

[0001] The present invention relates to the technical field of track detection, and particularly to a platform clearance measurement device. Background Art

[0002] To ensure the operation safety of trains and subways, it is required that buildings and equipment constructed around the railway shall not intrude into the cross-sectional contour line perpendicular to the track center line, which is called the platform clearance. The railway department has very strict requirements for the platform clearance and must meet the requirements of leaving a safety gap. In the specific measurement process, it is required that the minimum size measured by the measurement personnel meets the limit distance regulations of the cross section. The limit measurement of the railway department mainly measures the horizontal distance from the platform to the rail surface and the vertical height from the platform surface to the rail surface.

[0003] Currently, the detection of platform clearance in China mainly relies on contact measurement methods, using tools such as platform rulers and plumb bobs for time-consuming and laborious manual measurement. Until recent years, various non-contact distance measurements have gradually been applied to the measurement of platform clearance. However, due to the relatively high cost of non-contact distance measuring instruments and the relatively high technical level requirements for measurement personnel, it has not become the mainstream yet. However, non-contact measurement has higher accuracy, efficiency, and measurement range, and is also more in line with the needs of management and measurement, becoming the main research topic at home and abroad in recent years. Among many non-contact measurement methods, visual distance measurement has successfully stood out due to its flexibility and simplicity. However, due to the relatively large influence of ambient light on visual distance measurement and low accuracy, it is difficult to promote. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a platform clearance measurement device to solve the problem that visual distance measurement in the prior art is greatly affected by ambient light, has low accuracy, and is difficult to promote.

[0005] The present invention provides a platform clearance measurement device, including:

[0006] A device main body;

[0007] A control mechanism, arranged on the device main body for recording measurement data;

The measuring mechanism includes a support structure vertically arranged on the track inspection mechanism and a measuring component detachably arranged on the support structure. The measuring component is adjustably arranged on the support structure through an adjustment structure. The measuring component collects the coordinates of the platform edge and transmits the collected coordinate data to the control mechanism, so that the control mechanism obtains the platform clearance data through calibration parameters and coordinate conversion.

The support base is detachably arranged on the connection base.

[0012] Furthermore, the measuring component includes a measuring rod and a plurality of sensors arranged on the measuring rod. The measuring rod is adjustably arranged on the support rod through the adjustment structure. The sensors are used to obtain the lateral coordinates and vertical coordinates at the platform edge and transmit the lateral coordinates and vertical coordinates at the platform edge to the control mechanism, so that the control mechanism obtains the lateral coordinates and vertical coordinates with the track as the origin through calibration parameters and coordinate conversion, and calculates the height from the platform surface to the rail surface and the lateral distance from the platform edge to the track center through the lateral coordinates and vertical coordinates with the track as the origin.

[0013] Furthermore, the adjustment structure includes an adjustment rod connecting the measuring rod and the support rod. An adjustment part is provided between the adjustment rod and the measuring rod. The adjustment part is adjustably arranged on the measuring rod. The adjustment rod is fixed to the support rod through a mounting seat.

[0014] Furthermore, walking wheel sets are provided at one ends of the first track inspection mechanism and the second track inspection mechanism facing the track. The walking wheel sets push the platform clearance measuring device to walk on the rail surface of the track.

[0015] Furthermore, the walking wheel set includes a walking wheel and a measuring wheel connecting the track and the walking wheel. When the platform clearance measuring device walks on the rail surface of the track, the walking wheel rolls in cooperation with the rail surface, and the measuring wheel rolls in cooperation with the inner wall of the track.

[0016] Further, a first support member is provided between the support rod and the first track inspection mechanism, and a second support member is provided between the support rod and the device body.

[0017] Further, accommodation spaces are provided inside both the device body and the first track inspection mechanism, and the accommodation spaces are used to accommodate electronic components for measurement.

[0018] Further, the control mechanism includes a control device and a push rod connecting the control device and the device body, and the push rod is movably connected to the device body.

[0019] Further, a plurality of hand-held structures are provided on both the device body and the first track inspection mechanism.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: By arranging a measurement mechanism on the track inspection mechanism, the coordinate data of the platform edge can be effectively measured, and the corresponding platform clearance data can be obtained by the control mechanism according to the coordinate data, saving the time of manual measurement and improving the measurement efficiency. Further, the measurement assembly can be adjusted and arranged on the support structure through the adjustment structure, thereby ensuring the measurement angle of the measurement assembly and improving the measurement accuracy of the measurement assembly; and the track inspection mechanism and the device body form a T-shaped structure. During measurement, the device body and the track inspection mechanism can be set across the track, and the track inspection mechanism can slide parallel to the rail surface, so that the track inspection mechanism can also measure the gauge of the track.

[0035] Please refer to Figures 1 to 3, shown is the platform clearance measurement device in the embodiment of the present invention, including a device main body 100, a control mechanism 200 provided on the device main body 100, and track inspection mechanisms 300 respectively provided at both ends of the device main body 100. The track inspection mechanisms 300 are movably connected to the device main body 100 and can slide on the track. Among them, in this embodiment, the track inspection mechanisms 300 include a first track inspection mechanism 310 and a second track inspection mechanism 320. The first track inspection mechanism 310 is disposed at a right angle to the device main body 100 and forms a T-shaped structure. The measurement mechanism 400 is provided on the first track inspection mechanism 310 and is used for measuring platform clearance data. In other embodiments, the measurement mechanism 400 can also be provided on the second track inspection mechanism 320; specifically, the measurement mechanism 400 includes a support structure 410 vertically provided on the track inspection mechanism 300 and a measurement component detachably provided on the support structure 410. The measurement component is adjustably provided on the support structure 410 through an adjustment structure 500. The measurement component collects coordinates of the platform edge and transmits the collected coordinate data to the control mechanism 200, so that the control mechanism 200 obtains platform clearance data through calibration parameters and coordinate conversion.

[0036] It can be understood that by collecting the coordinates of the platform edge through the measurement component, and the control mechanism 200 obtains the corresponding platform clearance data according to the coordinate data, thereby saving the time of manual measurement, improving the measurement efficiency, and avoiding the errors caused by manual measurement; at the same time, the measurement component is adjustably provided on the support structure 410 through the adjustment structure 500, thereby ensuring the measurement angle of the measurement component and improving the measurement accuracy of the measurement component; and the first track inspection mechanism 310 and the device main body 100 form a T-shaped structure.

The track inspection mechanism 300 can slide parallel to the rail surface, so that the track inspection mechanism 300 can also measure the gauge of the track; each mechanism is detachably provided, which can further facilitate the installation and disassembly of the staff and improve the portability of the overall device.

[0037] Furthermore, a connection base 311 is provided in the middle of the first track inspection mechanism 310. The support structure 410 includes a support rod 411 and a support base 412 provided at one end of the support rod 411. The support base 412 is detachably provided on the connection base 311.

[0038] It can be understood that by detachably connecting the support base 412 and the connection base 311, when the platform clearance measurement device is not in use, the support rod 411 can be disassembled by means of disassembly, thereby reducing the storage area of the platform clearance measurement device and saving storage space.

[0039] It should be noted that, please refer to Figure 4 , in this embodiment, a connecting member 110 is provided on one side of the device main body 100 facing the first track inspection mechanism 310, and a fixing member corresponding to the connecting member 110 is provided on the first track inspection mechanism 310. The connecting member 110 includes a connecting sleeve and locking structures provided at both ends of the connecting sleeve. The locking structure includes a handwheel 111 and a locking bolt 112 provided on the handwheel 111. A threaded hole is correspondingly provided on the fixing member. The handwheel 111 drives the locking bolt 112 to rotate in the threaded hole so that the locking bolt 112 is threadedly connected to the threaded hole, thereby locking the connecting member 110 and the fixing member, and connecting the device main body 100 to the first track inspection mechanism 310.

[0040] Please refer to Figure 5 , in this embodiment, the measuring assembly includes a measuring rod 420 and a plurality of sensors provided on the measuring rod 420. The measuring rod 420 is adjustably arranged on the support rod 411 through the adjusting structure 500. The sensors are used to obtain the horizontal coordinates and vertical coordinates at the edge of the platform, and transmit the horizontal coordinates and the vertical coordinates at the edge of the platform to the control mechanism 200, so that the control mechanism 200 obtains the horizontal coordinates and vertical coordinates with the track as the origin through calibration parameters and coordinate conversion, and calculates the height from the platform surface to the rail plane and the horizontal distance from the platform edge to the track center through the horizontal coordinates and vertical coordinates with the track as the origin.

[0041] It should be noted that the sensors in this embodiment include sensors with ranging functions such as laser sensors and sensors with measuring functions such as mileage sensors. For example: line laser sensors; the measuring rod 420 is adjustably arranged on the support rod 411 through the adjusting structure 500, so as to ensure the measuring angle of the sensors, and improve the measuring accuracy and measuring effect of the sensors.

[0042] Specifically, the adjusting structure 500 includes an adjusting rod 510 connecting the measuring rod 420 and the support rod 411. An adjusting member 520 is provided between the adjusting rod 510 and the measuring rod 420. The adjusting member 520 is adjustably arranged on the measuring rod 420. The adjusting rod 510 is fixed to the support rod 411 through a mounting seat 530.

[0043] It should be noted that two adjusting grooves are provided on the measuring rod 420. When it is necessary to adjust the position of the measuring rod 420 through the adjusting member 520, the adjusting member 520 is loosened, and the adjusting member 520 is driven by the adjusting rod 510 to slide in the two adjusting grooves until it slides to the corresponding position, and then the adjusting member 520 is locked so that the adjusting member 520 is fixed on the measuring rod 420, thereby realizing the position adjustment of the measuring rod 420.

[0044] Please refer to Figure 6 Figure 6 , in this embodiment, walking wheel sets are provided at one ends of the first track inspection mechanism 310 and the second track inspection mechanism 320 facing the track, and the walking wheel sets push the platform clearance measuring device to walk on the rail surface of the track. Specifically, the walking wheel set includes a walking wheel 330 and a measuring wheel 340 connecting the track and the walking wheel 330. When the platform clearance measuring device walks on the rail surface of the track, the walking wheel 330 is in rolling fit on the rail surface, and the measuring wheel 340 is in rolling fit with the inner wall of the track.

[0045] It can be understood that when the platform clearance measuring device walks on the rail surface of the track, the walking wheel 330 can walk on the rail surface of the track, and at the same time, the measuring wheel 340 rolls on the inner wall of the track. The sensors provided on the measuring wheel 340 will detect the displacement amounts of the walking wheel 330 and the measuring wheel 340 and record them in real time. It can be understood that the actual gauge of the track can be calculated by using the sum of the displacement amounts of the measuring wheels 340 provided at both ends. At the same time, the measuring wheel 340 can also play a role in limiting to prevent the walking wheel 330 from shifting when walking on the rail surface.

[0046] Specifically, please refer to Figure 7 Figure 7 , a first support member 610 is provided between the support rod 411 and the first track inspection mechanism 310, and a second support member 630 is provided between the support rod 411 and the device main body 100.

[0047] It can be understood that the setting of the support member 600 can effectively support the support rod 411 and prevent the support rod 411 from shifting or tilting due to resistance during movement.

[0048] Furthermore, accommodation spaces are provided inside both the device main body 100 and the first track inspection mechanism 310, and the accommodation spaces are used to accommodate electronic components for measurement.

[0049] It can be understood that placing some electronic components in the accommodation space can ensure stable connection of the circuits, avoid circuit breakage caused by contact between the circuits and the outside, and at the same time can improve the utilization rate of components and reduce the manufacturing cost.

[0050] In this embodiment, the control mechanism 200 includes a control device and a push rod connecting the control device and the device main body 100. The push rod is movably connected to the device main body 100. A support frame for fixing the control device is installed on the push rod. A connecting frame is provided at the connection between the push rod and the device main body 100. The push rod is movably connected to the device main body 100 through the connecting frame. It should be understood that the control device can be a computer or other devices capable of collecting, storing, and processing data; the support frame can fix the control device more stably to prevent it from falling off during movement.

[0051] Further, a plurality of hand-held structures 700 are provided on both the device main body 100 and the first track inspection mechanism 310.

[0052] It can be understood that the setting of the hand-held structure 700 enables the staff to extract the components more conveniently, further improving the overall portability.

[0053] Specifically, for the platform clearance measurement device in this embodiment, after passing through the connecting line laser controller, the horizontal coordinates and vertical coordinates of the line laser sensor at the platform edge can be obtained. Through the calibration parameters and coordinate transformation, the horizontal coordinates and vertical coordinates with the track center as the origin can be obtained, that is, the height from the platform surface to the rail plane and the horizontal distance from the platform edge to the track center can be obtained. The track gauge and superelevation data can also be obtained through the track inspection system. The specific operation is as follows:

[0054] When the platform clearance measurement device is turned on, it communicates with the control device to obtain the platform contour information. After placing the track inspection trolley on the calibration table, the position information of the calibration line laser of the line laser sensor, the angle between the laser line and the rail plane are obtained, and the horizontal parameter, vertical parameter, and angle parameter are displayed in the parameter area of the calibration area.

[0055] The obtained calibration parameters are saved, and the measurement is carried out by manual measurement or automatic measurement. Among them, manual measurement is to perform static measurement when the measurement device stops stably, while automatic measurement is to control the measurement device to walk uniformly on the track, and the mileage data in the mileage sensor is read in real time to achieve dynamic measurement data. The static and / or dynamic measurement data is analyzed, so as to make the platform meet the limit distance requirements of the cross-section and ensure the operation safety of the train.

[0056] In summary, for the platform clearance measurement device in the above embodiments of the present invention, by arranging a measurement mechanism on the track inspection mechanism, the coordinate data of the platform edge can be effectively measured, and the corresponding platform clearance data can be obtained by the control mechanism according to the coordinate data, saving the time of manual measurement and improving the measurement efficiency. Further, the measurement component can be adjustably arranged on the support structure through the adjustment structure, thereby ensuring the measurement angle of the measurement component and improving the measurement accuracy of the measurement component; and the track inspection mechanism and the device body form a T-shaped structure. During measurement, the device body and the track inspection mechanism can be arranged across the track, and the track inspection mechanism can slide parallel to the rail surface, so that the track inspection mechanism can also measure the gauge of the track.
