Description

Technical Field

[0001] The present invention relates to the technical field of settlement measurement, and in particular to a non-contact settlement measuring device for railway tracks and a measuring method thereof. Background Art

[0002] With the continuous development of railway construction and the increase in train speed, the structural stability of railway tracks has gradually become a focus of attention. Track settlement and displacement may cause changes in track geometry, thereby affecting the smoothness and safety of train operation. When measuring the settlement height of railway tracks, it is generally necessary to place a height level rod in the area around the track. After aligning the measuring instrument with the level rod, the ground settlement height is measured by reading the scale surface of the level rod. Due to the relatively open area around the track, when measuring in areas with good weather, the surface of the level rod is easily exposed to direct light, causing the scale on the surface of the level rod to be overexposed and reflect light under the sunlight, which can easily lead to reading failure or measurement errors when reading the scale, affecting the subsequent measurement accuracy and efficiency.

[0014] The present invention has the following beneficial effects: 1. The present invention, through the moving component and the pushing component, can further block the scattered light irradiated on the scale plate from the side after the two flip plates are unfolded on both sides of the scale plate. Combined with the scale plate sliding to the inside of the level rod housing, it can form a surrounding semi-enclosed light-shielding cavity with the level rod housing, thereby reducing the situation in which sunlight shines on the surface of the scale plate during measurement, causing the scale on the surface of the scale plate to be overexposed and reflected under the sunlight, and reducing the situation in which reading failure or measurement error occurs due to the influence of light when measuring and reading the value on the scale plate, thereby improving the measurement accuracy and efficiency in subsequent measurements.

[0015] 2. The present invention, through the sliding component and the pushing component, can illuminate the two side edges of the scale plate at the angle after the flip plate is tilted by the flexible reflective plates on both sides of the level ruler shell, and perform secondary fill light on the two side edges of the scale plate located inside the level ruler shell. By fill light on the edges of the scale plate, it is possible to reduce the situation where the scale values ​​on the two side edges of the scale plate are blocked by the side walls of the level ruler shell when the scale plate slides to the inside of the level ruler shell, resulting in shadows on the scale values ​​on the two side edges of the scale plate, or blurred values ​​read by the measuring instrument due to insufficient light. By fill light on the edges of the scale plate, the clarity of the scale plate values ​​can be enhanced during measurement while reducing the occurrence of measurement shadows, thereby further improving the accuracy of measurement.

[0016] 3. The present invention uses a sliding assembly. When the flexible reflector slides in front of the multiple limit bars, the side walls of the flexible reflector will be blocked by the non-inclined surface of the limit bar, so that the flexible reflector forms a wave-like state when sliding, as shown in the figure. In the wave state, the flexible reflector is no longer a single plane, but is blocked by small planes at different angles. The flexible reflector in the wave state can reflect light in different directions, thereby expanding the reflection range. At the same time, the multi-angle reflection can also reduce the situation where the reflected light is parallel to the scale plate surface, making the edges of both sides of the scale plate clearer while reducing the situation where the reflected light irradiates the scale plate surface, thereby improving the subsequent measurement efficiency.

[0017] 4. The present invention uses a sliding assembly so that when the measurement is completed and the device is reset, the cleaning shaft can wipe and clean the surface of the flexible reflector again. Wiping and cleaning the surface of the flexible reflector by the cleaning shaft can reduce the situation where dust adheres to the surface of the flexible reflector during long-term measurement. By cleaning the flexible reflector before and after rotation, the influence of dust adhesion on the reflection intensity and range of light by the flexible reflector can be reduced, while ensuring the efficiency and stability of the flexible reflector during subsequent measurements.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The operation of the sliding mechanism 2 can cause the auxiliary mechanism 3 to move, thereby reducing the shadows during measurement and causing blur in the reading of values.

[0024] Body 1 includes: The bearing assembly 11 is installed on the top of the mounting base 101; The driving assembly 12 is installed on the side wall of the supporting assembly 11 .

[0025] The sliding mechanism 2 includes an inclined plate 201 installed inside the bearing assembly 11. The sliding mechanism 2 includes: Pushing assembly 21, which is installed on the side wall of inclined plate 1 201; The moving component 22 is installed on the side wall of the pushing component 21 through an elastic member.

[0026] Auxiliary mechanism 3 includes: The flip assembly 31 is installed inside the supporting assembly 11; Sliding assembly 32 . The sliding assembly 32 is installed on the side wall of the flip assembly 31 .

[0027] The carrying assembly 11 includes a level rod housing 111 fixedly connected to the top of the mounting base 101. The front and back of the level rod housing 111 are provided with rectangular grooves 112. The left inner wall of the level rod housing 111 is provided with four sliding grooves 113. The driving assembly 12 includes a driving rod 121 rotatably connected to the right outer wall of the level rod housing 111. The outer surface of the driving rod 121 is meshed with a toothed plate 122, and the toothed plate 122 is slidably connected to the inside of the level rod housing 111. First, the mounting base 101 with the supporting assembly 11 is installed on the top of the main body 1, and then the main body 1 is placed at the position to be measured. Subsequently, the staff starts the external measuring instrument to read the value on the scale plate 211.

[0028] The inclined plate 201 is rotatably connected to the top of the tooth plate 122. The side wall of the inclined plate 201 is provided with a C-shaped frame, which is fixedly connected to the left inner wall of the level rod housing 111. One end of the inclined plate 201 away from the tooth plate 122 is rotatably connected to a connecting block; The pushing assembly 21 includes a scale plate 211 slidably connected to the outer surface of the connecting block, and the scale plate 211 is slidably connected to the inside of the level rod housing 111. The scale plate 211 is rotatably connected to one side of the sliding groove 113 with four inclined plates 212. Before starting the measurement, the staff rotates the driving rod 121 to drive the tooth plate 122 engaged with it to move downward. When the tooth plate 122 moves downward, it will drive the inclined plate 1 201 to move downward synchronously. Since the side wall of the inclined plate 1 201 is blocked by the C-shaped frame, when the tooth plate 122 drives the inclined plate 1 201 to move downward, the inclined plate 1 201 will rotate to a nearly vertical state under the obstruction of the C-shaped frame.

[0029] The elastic member includes a sliding frame 221 rotatably connected to the end of the second inclined plate 212 away from the scale plate 211, and the side wall of the sliding frame 221 is slidably connected to the interior of the sliding groove 113; A return spring is fixedly connected to one side of the sliding frame 221 close to the rectangular slot 112 , and an end of the return spring away from the sliding frame 221 is fixedly connected to the inner wall of the level rod housing 111 ; The moving assembly 22 includes a hollow plate 222 rotatably connected to the inside of the sliding frame 221. The internal sliding of the two hollow plates 222 passes through the limit rod 223. When the scale plate 211 is pulled by the inclined plate 201 to slide, the sliding of the scale plate 211 will push the sliding frame 221 to slide. When the sliding frame 221 slides, it will drive the hollow plate 222 to rotate because the interior of the hollow plate 222 is restricted by the limit rod 223 and the surface short block.

[0030] The two limit rods 223 are rotatably connected to the interior of the level rod housing 111. One end of the hollow plate 222 away from the sliding frame 221 is rotatably connected to the connecting block 2, and the outer surfaces of the two connecting blocks are slidably connected to the flip plate 124, and the flip plate 124 is rotatably connected to the inside of the level rod housing 111; A short block is fixedly connected to the outer surface of the limiting rod 223 inside the hollow plate 222. When the hollow plate 222 rotates and slides forward, the sliding of the hollow plate 222 will push the flip plate 1 224 to rotate in the front area of ​​the scale plate 211. At this time, the two flip plates 1 224 will form an expanded state and block on both sides of the front area of ​​the scale plate 211.

[0031] The flip assembly 31 includes two connecting plates 311 fixedly connected to the outer surface of the limiting rod 223, a cleaning shaft 312 is rotatably connected between the two connecting plates 311, and a center rod 313 is rotatably connected between the two connecting plates 311; The sliding assembly 32 includes a second flip plate 321 rotatably connected to the interior of the rectangular groove 112. A plurality of limit bars 322 are fixedly connected to the right inner wall of the second flip plate 321. The limit bars 322 are arranged in groups of two in a staggered manner, and the groups of limit bars 322 are arranged at equal distances. The side wall of the limiting strip 322 is inclined; A flexible reflective plate 323 is slidably connected between the plurality of limit bars 322 , a spring plate 324 is fixedly connected to the side wall of the flexible reflective plate 323 , and an elastic end of the spring plate 324 is fixedly connected to the outer surface of the central rod 313 ; The side wall of the flip plate 2 321 is fixedly connected to two curved spring plates, and the end of the curved spring plate away from the flip plate 2 321 is fixedly connected to the side wall of the level ruler housing 111. Since the connecting plate 311 is fixedly connected to the limit rod 223, the hollow plate 222 will drive the limit rod 223 to rotate under the push of the sliding frame 221. At this time, when the limit rod 223 rotates, it will drive the connecting plate 311 connected to it to rotate synchronously. When the connecting plate 311 rotates, it will push the flexible reflective plate 323 and the flip plate 2 321 to rotate.

[0032] A non-contact railway track settlement measuring device, the method comprising the following steps: S1: Assembly and placement: First, install the mounting base 101 with the bearing assembly 11 on the top of the main body 1, and then place the main body 1 at the position to be measured; S2: Measurement and reading: The staff then starts an external measuring instrument to read the value on the scale plate 211, and then completes the settlement measurement around the track through calculation by the measuring instrument.

[0033] When in use, first install the mounting base 101 with the bearing assembly 11 on the top of the main body 1, then place the main body 1 at the position to be measured, and then the staff starts the external measuring instrument to read the value on the scale plate 211, and then completes the settlement measurement around the track through calculation by the measuring instrument.

[0034] Before starting the measurement, the staff rotates the driving rod 121 to drive the toothed plate 122 engaged therewith to move downward. When the toothed plate 122 moves downward, it will drive the inclined plate 201 to move downward synchronously. Since the side wall of the inclined plate 201 is blocked by the C-shaped frame, when the toothed plate 122 drives the inclined plate 201 to move downward, the inclined plate 201 will rotate to a nearly vertical state under the blockage of the C-shaped frame. When the inclined plate 201 rotates, it will pull the scale plate 211 to slide inside the level rod housing 111 through the sliding block 1. At this time, the level The ruler housing 111 can block part of the direct light from shining on the surface of the scale plate 211. At the same time, since the inclined plate 212 is in an inclined state between the sliding frame 221 and the scale plate 211, when the scale plate 211 is pulled by the inclined plate 1 201 to slide, the sliding of the scale plate 211 will push the sliding frame 221 to slide. When the sliding frame 221 slides, it will drive the hollow plate 222 to rotate. Since the interior of the hollow plate 222 is restricted by the limit rod 223 and the surface short block, when the hollow plate 222 rotates, it will The movable limit rod 223 rotates synchronously. At the same time, the hollow plate 222 will slide forward on the surface of the limit rod 223 under the restriction of the short block when rotating. When the hollow plate 222 rotates and slides forward, the sliding of the hollow plate 222 will push the flip plate 1 224 to rotate in the front area of ​​the scale plate 211. At this time, the two flip plates 1 224 will form an expanded state and block on both sides of the front area of ​​the scale plate 211. After the two flip plates 1 224 are expanded on both sides of the scale plate 211, they can further block the lateral movement of the scale plate 211. The scattered light irradiated by the scale plate 211, combined with the scale plate 211 sliding into the interior of the level rod housing 111, can form a surround-type semi-enclosed light-shielding cavity with the level rod housing 111, thereby reducing the sunlight shining on the surface of the scale plate 211 during measurement, causing the scale on the surface of the scale plate 211 to be overexposed and reflected under the sunlight, and reducing the reading failure or measurement error caused by the influence of light when measuring and reading the value on the scale plate 211, thereby improving the measurement accuracy and efficiency in subsequent measurements.

[0035] Because the connecting plate 311 is fixedly connected to the limiting rod 223, the hollow plate 222 will drive the limiting rod 223 to rotate under the push of the sliding frame 221. At this time, when the limiting rod 223 rotates, it will drive the connecting plate 311 connected thereto to rotate synchronously. When the connecting plate 311 rotates, it will push the flexible reflector 323 and the flip plate 2 321 to rotate. When the flip plate 2 321 rotates, it will compress the curved spring plate on the side wall and form a certain angle with the level ruler shell 111 when rotating. Then, when light is irradiated onto the level ruler shell 111, part of the sunlight will irradiate the flexible reflector 323. At this time, the flexible reflector 323 will reflect the irradiated light through the rectangular groove 112 to the inside of the level ruler shell 111, and pass through the level ruler shell The reflection of light by the flexible reflective plates 323 on both sides of 111 can illuminate the edges of the scale plate 211 on both sides at the angle after the flip plate 321 is tilted, and perform secondary fill light on the edges of the scale plate 211 on both sides located inside the level ruler housing 111. By fill light on the edges of the scale plate 211, it is possible to reduce the situation where when the scale plate 211 slides into the interior of the level ruler housing 111, the edges of the scale plate 211 on both sides are blocked by the side walls of the level ruler housing 111, resulting in shadows on the scale values ​​on the edges of the scale plate 211 or blurred values ​​read by the measuring instrument due to insufficient light. By fill light on the edges of the scale plate 211, the clarity of the values ​​of the scale plate 211 can be enhanced during measurement while reducing the occurrence of measurement shadows, thereby further improving the accuracy of measurement.

[0036] When the light source 323 is in the state of being rotated, the light source 323 of the light source 323 is in the state of being rotated. Figure 9As shown in , the flexible reflector 323 is no longer a single plane in the wavy state, but is blocked by small planes at different angles. The flexible reflector 323 in the wavy state can reflect light in different directions, thereby expanding the reflection range. At the same time, multi-angle reflection can also reduce the situation where the reflected light is parallel to the surface of the scale plate 211, making the edges on both sides of the scale plate 211 clearer while reducing the situation where the reflected light irradiates the surface of the scale plate 211, thereby improving subsequent measurement efficiency.

[0037] When the rotation of the limit rod 223 drives the connecting plate 311 to rotate synchronously, the rotation of the connecting plate 311 will drive the cleaning shaft 312 to rotate synchronously. When the connecting plate 311 drives the cleaning shaft 312 to rotate, it will also push the flip plate 221 to rotate outward. At the same time, when the connecting plate 311 drives the cleaning shaft 312 to rotate, the cleaning shaft 312 will slide on the surface of the flexible reflector 323. The sliding of the cleaning shaft 312 can wipe and clean the surface of the flexible reflector 323. At the same time, when the measurement is completed and reset, the cleaning shaft 312 can also wipe and clean the surface of the flexible reflector 323 again. Wiping and cleaning the surface of the flexible reflector 323 by the cleaning shaft 312 can reduce the situation that dust adheres to the surface of the flexible reflector 323 during long-term measurement. By cleaning the flexible reflector 323 before and after rotation, the influence of dust adhesion on the reflection intensity and range of the flexible reflector 323 on light can be reduced, and at the same time, the efficiency and stability of the flexible reflector 323 when measuring again in the future can be ensured.
