Description

Technical Field

[0001] The present invention relates to the technical field of track deformation detection, and in particular to a device for detecting the deformation quality of railway tracks. Background Art

[0002] Railway tracks usually consist of two parallel rails, which are fixed on sleepers, with ballast under them. They are fastened by rail supports, fasteners, rail clamps, rail clamps, spring bars, rail spikes and other railway accessories. During railway transportation, the rails are subject to the load, bending and lateral force of the train, as well as external factors such as temperature, humidity and foundation conditions. Long-term use will cause the rails to deform, and the deformation of the rails will lead to some safety problems during railway transportation, such as: generating noise and vibration, increasing train wear and fatigue, and reducing train speed and safety.

[0003] At present, when detecting railway deformation, the commonly used detection method is that the detection personnel carry detection tools to measure the distance between the corresponding positions on the inner side of the two tracks, and perform fixed-point detection on multiple positions on the track, and then record the detection data, and analyze the detection data to determine whether the track deformation at the detection point exceeds the standard range. However, this detection process is easy to ignore the situation where the two tracks have the same deformation at the same time. For example, hot weather causes the rails and sleepers to shift, or the local rails bulge upward slightly, the track has been deformed and cannot be observed by the naked eye, which leads to errors in track deformation detection.

DETAILED DESCRIPTION

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] Reference Figure 1-8 A device for detecting deformation quality of railway track comprises a frame 1, track wheels 4 are installed at both ends of the frame 1, and a driving motor 6 for driving the track wheels 4 to rotate is installed at the bottom of the frame 1, a box 3 is installed on the top of the frame 1, and a battery pack 2 is plugged into the box 3, a rotating motor 11 is installed at both ends of the frame 1, and an adjusting arm 10 is installed on the outer side of the output shaft of the rotating motor 11, an angle sensor 103 is installed in the middle of the adjusting arm 10, a fixed cross bar 7 is installed at the front end position of the adjusting arm 10, and a detection bracket 8 is rotatably installed between the two ends of the fixed cross bar 7, and track lateral deformation detection mechanisms 5 are sleeved on both ends of the bottom of the detection bracket 8, a track height deformation detection mechanism 9 is installed on the top of the fixed cross bar 7, and height deformation detection components 94 are screwed at the four corners of the track height deformation detection mechanism 9, the bottom of the height deformation detection component 94 is rollingly connected to the four corners of the top of the detection bracket 8, and distance measuring mechanisms 18 for detecting track connection seams are installed at both ends of the bottom of the detection bracket 8.

[0021] In the present invention, track lateral deformation detection mechanisms 5 are installed at both ends of the device in the opposite direction to the track wheel 4. When entering the detection position, the device is calibrated, and the two track lateral deformation detection mechanisms 5 always maintain the thrust to squeeze the outer side surface of the track inward. At the same time, the height deformation detection component 94 at the upper end is rotated so that the four height deformation detection components 94 apply the same pressure to the top four corners of the detection bracket 8. When the device moves on the track, the distance between the two tracks is detected by using the change in the distance between the track lateral deformation detection mechanisms 5 on both sides. When the track is laterally deformed, the corresponding track lateral deformation detection mechanism 5 is affected by the deformation and moves sideways accordingly, so that the size data and position information of the lateral deformation can be obtained. When the track is deformed upward, the side of the track lateral deformation detection mechanism 5 is lifted when passing by, and then The detection bracket 8 is driven to partially produce an upward position, and the height deformation detection component 94 located above is squeezed to obtain the track height change information. At the same time, the end position of the detection bracket 8 drives the bottom structure of the adjustment arm 10 to deflect, and the angle deflection information is obtained through the angle sensor 103. The distance measuring mechanism 18 spans the inner and outer sides of the track. When the size of the track joint is abnormal, the signals at both ends of the distance measuring mechanism 18 are received by each other across the gap of the joint, so that the size information of the joint can be obtained, and the video of the passing sleepers, rail fasteners, spikes and nuts can be recorded. When the track lateral deformation detection mechanism 5, the track height deformation detection mechanism 9 and the distance measuring mechanism 18 detect abnormal data, they are marked at the corresponding time of the recorded video, so that the inspectors can quickly find the deformation area and the type of deformation, and provide data support for the staff to maintain the track.

[0022] As a further solution in the present invention, the adjusting arm 10 includes a rotating arm 101 connected to the rotating motor 11, and a detecting rod 104 connected to the fixed cross bar 7. A buffer sleeve 102 is installed on the outer side of the rotating arm 101, and the angle sensor 103 is installed between the buffer sleeve 102 and the detecting rod 104. In the present invention, the adjusting arm 10 carries the detecting component of the device. When the adjusting arm 10 puts down the detecting bracket 8 at the front end, the signal of the angle sensor 103 is reset to zero. Afterwards, when one side of the track is deformed by a protrusion, one end of the detecting bracket 8 is lifted, thereby driving the detecting rod 104 to rotate and tilt to one side, driving the angle sensor 103 to generate a rotation signal to obtain the track protrusion deformation information.

[0023] As a further solution in the present invention, the detection bracket 8 includes two connecting sleeves 81 rotatably installed on the ends of the fixed cross bar 7, and a support frame 84 arranged parallel to the fixed cross bar 7, and support shafts 83 slidably matched with the track lateral deformation detection mechanism 5 are arranged at both ends of the support frame 84, and a fixing frame 82 with an inverted U-shaped structure is installed between the ends of the support shaft 83 and the ends of the connecting sleeve 84. In the present invention, the track lateral deformation detection mechanism 5 is installed at both ends of the support frame 84, and the detection bracket 8 is vertically spanned between the two rails under the constraint of the adjusting arm 10, so that the four track lateral deformation detection mechanisms 5 are symmetrically distributed on both sides of the railway track, and the track lateral deformation detection mechanism 5 is tightly attached to the surface of the rail to accurately detect deformation defects on the surface of the rail, and the four track lateral deformation detection mechanisms 5 are overlapped and compared with each other to avoid erroneous detection data and improve the accuracy of railway track deformation quality detection.

[0024] As a further solution in the present invention, the track height deformation detection mechanism 9 includes two support rings 92 fixedly connected to the fixed cross bar 7, and a positioning frame 91 arranged parallel to the fixed cross bar 7 is installed between the tops of the two support rings 92, and locking nuts 93 that are locked and matched with the support rings 92 are screwed on both sides of the fixed cross bar 7. The height deformation detection component 94 is screwed to the four corners of the positioning frame 91. In the present invention, when the device is on the track, the positioning frame 91 is arranged parallel to the detection bracket 8. At this time, the height deformation detection component 94 is rotated to make its bottom The pressure at the top and the four corners of the detection bracket 8 are the same, and the detection bracket 8 is rotatably connected to the two ends of the fixed cross bar 7. When the track lateral deformation detection mechanism 5 moves on the rail and encounters a local bulge of the rail, the front end of the detection bracket 8 moves upward, thereby changing the pressure of the height deformation detection component 94 and the front side of the detection bracket 8. At the same time, one end of the detection bracket 8 is lifted, and the adjustment arm 10 is driven to produce axial rotation movement to obtain the height data and deformation direction of the rail bulge deformation. Multiple sets of data are coordinated and verified with each other to improve the accuracy of the detection data.

[0025] As a further solution in the present invention, the height deformation detection component 94 includes a threaded sleeve 941 screwed on the four corners of the positioning frame 91, and a vertical pressure sensor 944 is inserted into the interior of the threaded sleeve 941, a detection ball head 943 is installed at the bottom of the vertical pressure sensor 944, and a vertical push spring 942 is installed between the outer side of the vertical pressure sensor 944 and the threaded sleeve 941. In the present invention, the vertical pressure sensor 944 is installed in the interior of the threaded sleeve 941 through the vertical push spring 942. In the detection preparation stage, the height of the vertical pressure sensor 944 is adjusted by rotating the outer threaded sleeve 941, so that the four vertical pressure sensors 944 maintain the same pressure on the detection bracket 8, and then the height data of the track uplift deformation is obtained through the deformation of the vertical push spring 942 and the detection data of the vertical pressure sensor 944.

[0026] As a further solution in the present invention, the track lateral deformation detection mechanism 5 includes an elastic telescopic sleeve 52, a transition rotating ring 54 and a detection wheel 51 which are sleeved on the outside of the support shaft 83, and a lateral pressure sensor 53 is installed between the other end of the elastic telescopic sleeve 52 and the fixed frame 82, and the transition rotating ring 54 is installed between the elastic telescopic sleeve 52 and the detection wheel 51. In the present invention, when located at the detection position, the detection wheel 51 and the track wheel 4 are set in the opposite direction, and then the detection wheel 51 always maintains pressure on the outside of the rail under the thrust of the elastic telescopic sleeve 52, and the lateral pressure sensor 53 obtains the pressure between the detection wheel 51 and the outer side of the track. When the device moves on the track, the lateral pressure sensor 53 is in a dynamic equilibrium state. When the track undergoes lateral deformation and deviation, the value of the lateral pressure sensor 53 changes accordingly, thereby obtaining accurate data on the lateral deformation of the track.

[0027] As a further solution in the present invention, two electric push rods 85 are installed on the top of the support frame 84, and a U-shaped pushing piece 86 is installed at the front end position of the electric push rod 85. The pushing piece 86 is slidably connected to the support shaft 83. In the present invention, the pushing piece 86 is away from the compressed elastic telescopic sleeve 52 in the preparation stage to avoid pressure on the elastic telescopic sleeve 52. When the device is detecting, the electric push rod 85 drives the pushing piece 86 to move in the direction of the track lateral deformation detection mechanism 5, compresses the elastic telescopic sleeve 52, and detects and calibrates the lateral pressure sensor 53. When the detection wheel 51 is located above the track, the pushing piece 86 contracts and resets.

[0028] As a further solution in the present invention, the ranging mechanism 18 includes a ranging bracket 181, and infrared gratings 183 are screwed at both ends of the bottom of the ranging bracket 181, and a camera 182 is installed at the bottom of the ranging bracket 181. In the present invention, the infrared gratings 183 are respectively arranged on both sides of the rails. When an abnormality occurs in the gap between the rails, the infrared grating 183 passes through and is received by the receiver on the opposite side, thereby obtaining the size information of the gap between the rail joints. At the same time, the camera 182 records the video information of the rail surface during the device detection process, and detects the rail surface, fasteners, spikes and nuts. When the rail is abnormally deformed, the staff can quickly determine the deformation information through the video, which provides convenience for the staff to maintain the rail.

[0029] As a further solution in the present invention, a placement bracket 14 is installed on both sides of the top of the frame 1, and a fixing plate 12 compatible with the detection bracket 8 is provided at the top position of the placement bracket 14. In the present invention, after the operation of the device is completed, the rotating motor 11 lifts the detection bracket 8 and the equipment above it off the track through the adjusting arm 10, and places them on the fixing plate 12, which is convenient for maintenance and storage of the device.

[0030] As a further solution in the present invention, a solenoid valve 16 is installed at the bottom of the frame 1, and spray pipes 17 are installed on both sides of the solenoid valve 16. A liquid storage tank 13 is installed on the top of the box body 3, and a pipeline 15 and a delivery pump are installed between the side of the liquid storage tank 13 and the solenoid valve 16. In the present invention, two sets of railway track deformation detection components are provided, which are respectively installed at the two ends of the frame 1, and a solenoid valve 16 and a spray pipe 17 are provided between the two sets of railway track deformation detection components. When the component located at the front end detects that there is an abnormality in the track, the solenoid valve 16 and the spray pipe 17 quickly spray marks on the surface of the track. When the rear end verifies that the track is abnormally deformed, the magnetic valve 16 and the spray pipe 17 spray marks again, and then spray marks before and after the abnormal section of the track, which is convenient for maintenance personnel to construct and operate. At the same time, it avoids spraying paint directly on the abnormal section to affect the subsequent verification of the staff.

[0031] When in use, track lateral deformation detection mechanisms 5 are installed at both ends of the device in the opposite direction of the track wheel 4. When entering the detection position, the device is calibrated, and the two track lateral deformation detection mechanisms 5 always maintain the thrust of squeezing the outer side of the track inward. At the same time, the height deformation detection component 94 at the upper end is rotated so that the four height deformation detection components 94 apply the same pressure to the four corners of the top of the detection bracket 8. When the device moves on the track, the distance between the two tracks is detected by using the change in the distance between the track lateral deformation detection mechanisms 5 on both sides. When the track is laterally deformed, the corresponding track lateral deformation detection mechanism 5 is affected by the deformation and moves sideways accordingly, so that the size data and position information of the lateral deformation can be obtained. When the track is deformed upward, the side of the track lateral deformation detection mechanism 5 is lifted when passing by, and then The detection bracket 8 is driven to partially produce an upward position, and the height deformation detection component 94 located above is squeezed to obtain the track height change information. At the same time, the end position of the detection bracket 8 drives the bottom structure of the adjustment arm 10 to deflect, and the angle deflection information is obtained through the angle sensor 103. The distance measuring mechanism 18 spans the inner and outer sides of the track. When the size of the track joint is abnormal, the signals at both ends of the distance measuring mechanism 18 are received by each other across the gap of the joint, so that the size information of the joint can be obtained, and the video of the passing sleepers, rail fasteners, spikes and nuts can be recorded. When the track lateral deformation detection mechanism 5, the track height deformation detection mechanism 9 and the distance measuring mechanism 18 detect abnormal data, they are marked at the corresponding time of the recorded video, so that the inspectors can quickly find the deformation area and the type of deformation, and provide data support for the staff to maintain the track.
