Description

Technical Field

[0001] This utility model relates to the field of track inspection technology, specifically to an electronic track gauge for track gauge inspection. Background Technology

[0002] In modern railway transportation systems, the track, as the infrastructure for train operation, plays a decisive role in the safety and smooth operation of trains due to the accuracy of its gauge. With the rapid development of the railway industry, whether it's the continuous upgrading of trunk railways or the widespread construction of urban rail transit, the demand for track gauge inspection is constantly increasing. Accurate gauge inspection can promptly detect problems such as track deformation and wear, thus providing crucial information for track maintenance and repair, ensuring the efficiency and safety of railway transportation.

[0003] Currently, mechanical gauges and electronic gauges are commonly used tools in track gauge inspection. Mechanical gauges mainly rely on manual operation and scale reading to measure track gauge, while electronic gauges use electronic sensors and other technologies for measurement, which has a certain improvement in accuracy compared to mechanical gauges.

[0004] However, existing testing tools and technologies have some shortcomings. The measurement accuracy of mechanical track gauges is greatly affected by human factors such as the operator's skill level and reading habits, which can easily lead to large errors. Moreover, the scale reading process of mechanical track gauges is relatively cumbersome and time-consuming, resulting in low testing efficiency. For electronic track gauges, the testing range of most products is fixed and cannot be flexibly adjusted to adapt to tracks with different gauges. When encountering special-purpose track lines, such as dedicated tracks inside some large factories or new rail transit test lines, where the gauge differs from the conventional standard, it is necessary to replace the track gauge with a matching one. This undoubtedly increases testing costs, and frequent equipment changes also interrupt the testing process, significantly reducing testing efficiency and failing to meet the needs of actual testing work. Therefore, we propose an electronic track gauge for track gauge testing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an electronic track gauge for track gauge detection. It can flexibly adjust the detection range, accurately measure tracks with different gauges, effectively avoid human error, improve detection efficiency and reduce costs, and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electronic track gauge for track gauge detection, comprising a gauge body, a probe fixedly sleeved on the left end of the gauge body, a detection device for detecting distance inside the gauge body, a horizontal column on the left end of the lower side of the gauge body, and an extension mechanism.

[0007] The extension mechanism includes an extension ruler, a self-locking groove, mounting rods, friction blocks, and sliding grooves. The extension ruler is slidably connected inside the ruler body. A moving measuring head is provided at the right end of the extension ruler. A self-locking groove is provided on the upper side of the extension ruler. Mounting rods are symmetrically distributed at the right end of the upper side wall of the ruler body. Sliding grooves are provided on the upper side of each friction block. Each sliding groove is slidably connected to the lower end of the adjacent mounting rod on the upper side. Each friction block is installed in conjunction with the inner wall adjacent to the self-locking groove. The detection range can be flexibly adjusted to accurately measure tracks with different gauges.

[0008] Furthermore, the expansion mechanism also includes a mounting column and a pressing block. A sliding hole is provided at the right end of the upper side wall of the ruler body. The mounting column is slidably connected inside the sliding hole. A pressing block is provided at the lower end of the mounting column. All friction blocks are installed in conjunction with the pressing block to facilitate pressing the friction blocks and make the friction blocks fit tightly with the self-locking groove.

[0009] Furthermore, the expansion mechanism also includes a limiting frame, a limiting rod, and hooks. The upper end of the mounting column is provided with a limiting rod, and hooks are rotatably connected to both ends of the outer arc of the limiting rod. A limiting frame is provided between the two mounting rods, and the hooks are all installed in cooperation with the limiting frame to maintain the position of the expansion ruler after expansion.

[0010] Furthermore, the expansion mechanism also includes mounting grooves and rollers. Mounting grooves are provided on both the front and rear sides of the expansion ruler. Rollers are rotatably connected between the upper and lower inner walls of the mounting grooves. The rollers are in contact with the inner walls adjacent to the ruler body to ensure smooth sliding when the expansion ruler is expanded.

[0011] Furthermore, a battery is located on the left side inside the ruler body, and a microcontroller is located on the upper side of the ruler body. The input terminal of the microcontroller is electrically connected to the output terminal of the battery for stable control.

[0012] Furthermore, the detection device is a laser rangefinder. A groove is provided on the left side of the extended ruler, and the laser rangefinder is installed inside the groove. The laser rangefinder is bidirectionally electrically connected to the microcontroller. A detection plate is provided on the left end of the top wall of the ruler. The laser rangefinder is installed in conjunction with the detection plate for measuring distance.

[0013] Furthermore, a display is mounted on the upper side of the ruler, and the display is bidirectionally electrically connected to the microcontroller to display the measurement values.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This electronic track gauge for track measurement has the following advantages:

[0015] When this track gauge is used for track gauge testing, the testing range of the track gauge can be flexibly adjusted according to different track gauges. By lifting the pressing block by the mounting column, the extended gauge can slide freely. After the extended gauge is stretched to bring the moving measuring head into place, the pressing block is pressed down, and the extended gauge is locked by its cooperation with the friction block and the self-locking groove. This ensures that the track gauge can adapt to various track gauges, improves versatility, reduces the trouble of replacing track gauges, reduces testing costs, and improves testing efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6This embodiment provides a technical solution: an electronic track gauge for track measurement, comprising a gauge body 1, a battery 5 disposed on the left side inside the gauge body 1, a microcontroller 9 disposed on the upper side of the gauge body 1, the input terminal of the microcontroller 9 being electrically connected to the output terminal of the battery 5, a probe 3 fixedly sleeved on the left end of the gauge body 1, a detection device for detecting distance disposed inside the gauge body 1, the detection device being a laser rangefinder 6, a groove being formed on the left side of the extended gauge 201, the laser rangefinder 6 being installed inside the groove, and the laser rangefinder 6 and the microcontroller 9 being bidirectionally connected. Electrically connected, a detection plate 11 is provided on the top left end of the ruler body 1. A laser rangefinder 6 is installed in conjunction with the detection plate 11 (before the track gauge is extended, the distance between the laser rangefinder 6 and the detection plate 11 is recorded as zero; after the track gauge is extended, the laser rangefinder 6 detects the distance between itself and the detection plate 11, and the result is the current track gauge after adding the fixed detection value of the track gauge itself). A display 7 is installed on the upper side of the ruler body 1, and the display 7 is electrically connected to the microcontroller 9 in both directions. A horizontal column 10 is provided on the lower left end of the ruler body 1. The column 10 and the ruler 1 are perpendicular to each other. When using this electronic track gauge for gauge measurement, the ruler 1 is first placed on the track. The horizontal column 10 on the lower left side of the ruler 1 is used to initially determine whether the track gauge is placed horizontally with the track to ensure the accuracy of the measurement. The display 7 and the laser rangefinder 6 are operated by controlling the microcontroller 9. First, the laser rangefinder 6 starts to work. Before the track gauge is extended, the distance between the laser rangefinder 6 and the detection plate 11 is recorded as zero. After the track gauge is extended, the laser rangefinder 6 emits a laser to detect the distance between itself and the detection plate 11. The laser rangefinder 6 transmits the measurement data to the microcontroller 9. After receiving the data, the microcontroller 9 performs calculations based on the fixed detection values ​​of the track gauge itself (such as the distance between the probe 3 and the moving probe 4 in the initial position and other related fixed values) to finally obtain the current track gauge data. Then, the microcontroller 9 transmits the processed track gauge data to the display 7. Finally, the display 7 displays the track gauge value intuitively for easy reading by the staff and facilitates the detection of track gauge. It also includes an extension mechanism 2.

[0025] Extending mechanism 2 includes an extending ruler 201, a self-locking groove 204, a mounting rod 205, friction blocks 206, and a sliding groove 207. The extending ruler 201 is slidably connected inside the ruler body 1. A moving measuring head 4 is provided at the right end of the extending ruler 201. A self-locking groove 204 is provided on the upper side of the extending ruler 201. The mounting rods 205 are symmetrically distributed at the right end of the upper sidewall of the ruler body 1. Sliding grooves 207 are provided on the upper side of each friction block 206, and each sliding groove 207 is slidably connected to the lower end of the adjacent mounting rod 205 on the upper side. Each friction block 206 is fitted into the inner wall adjacent to the self-locking groove 204. Extending mechanism 2 also includes a mounting post 208 and a pressing block 209. A sliding hole 8 is provided at the right end of the upper sidewall of the ruler body 1, and the mounting post 208 is slidably connected inside the sliding hole 8. The lower end of the column 208 is provided with a pressing block 209, and the friction blocks 206 are all installed in conjunction with the pressing block 209 (the upper ends of the two friction blocks 206 are provided with inclined grooves, and the pressing block 209 is an inverted trapezoidal pressing block. The pressing block 209 can move downward to cooperate with the inclined grooves, pressing the two friction blocks 206 to move forward and backward). The expansion mechanism 2 also includes a limiting frame 210, a limiting rod 211, and a hook 212. The upper end of the mounting column 208 is provided with a limiting rod 211, and the front and rear ends of the outer arc front of the limiting rod 211 are rotatably connected to hooks 212. A limiting frame 210 is provided between the two mounting rods 205, and the hooks 212 are all installed in conjunction with the limiting frame 210. The expansion mechanism 2 also includes a mounting groove 202 and a roller 203. The front and rear sides of the expansion ruler 201 are all An installation groove 202 is provided, and rollers 203 are rotatably connected between the upper and lower inner walls of the installation groove 202. All rollers 203 contact the adjacent inner walls of the ruler body 1. When measuring tracks with different gauges, the ruler body 1 is held by hand, and the pressing block 209 is lifted upwards via the installation column 208. At this time, the friction block 206 loses the pressing action of the pressing block 209, reducing its contact with the inner wall of the self-locking groove 204. The extended ruler 201 can then slide freely inside the ruler body 1. The rollers 203 in the installation grooves 202 on the front and rear sides of the extended ruler 201 contact the inner walls of the ruler body 1, reducing friction during sliding and ensuring smooth sliding. Pulling the extended ruler 201 to the right moves the moving measuring head 4 to the appropriate position. The position is adapted to tracks with different gauges. After the extension ruler 201 is stretched to the required length, the pressing block 209 is pressed down by the mounting column 208. The pressing block 209 moves downward. Since the pressing block 209 is an inverted trapezoid, it cooperates with the inclined groove opened at the upper end of the friction block 206 when it moves downward, pressing the two friction blocks 206 to move forward and backward respectively, so that the friction blocks 206 are tightly attached to the inner wall of the self-locking groove 204, thereby locking the position of the extension ruler 201. At the same time, the two hooks 212 of the limit rod 211 are rotated. The hooks are hung on the arc surface of the limit frame 210 to maintain the position of the mounting column 208, further maintaining the position of the extension ruler 201 after extension and preventing it from sliding accidentally. Through the extension of the extension mechanism 2, the ruler can be adapted to tracks with different gauges.

[0026] The working principle of the electronic track gauge measuring instrument provided by this utility model is as follows: When using this electronic track gauge measuring instrument, first place the gauge body 1 on the track. Use the horizontal column 10 on the lower left side of the gauge body 1 to initially determine whether the gauge is placed horizontally with the track, ensuring the accuracy of the measurement. If a track with a different gauge needs to be measured, hold the gauge body 1 by hand, and then lift the pressing block 209 upward through the mounting column 208. At this time, the friction block 206 loses the pressing action of the pressing block 209, and the fit with the inner wall of the self-locking groove 204 decreases, allowing the extended gauge 201 to... The ruler body 1 slides freely inside. The rollers 203 in the mounting grooves 202 on the front and rear sides of the extended ruler 201 contact the inner wall of the ruler body 1, reducing friction when the extended ruler 201 slides, ensuring smooth sliding. Pulling the extended ruler 201 to the right moves the moving measuring head 4 to a suitable position to adapt to tracks with different gauges. When the extended ruler 201 is stretched to the required length, the pressing block 209 is pressed down by the mounting column 208. The pressing block 209 moves downward. Since the pressing block 209 is an inverted trapezoid, it cooperates with the inclined groove at the upper end of the friction block 206 when it moves downward, compressing... The two friction blocks 206 move forward and backward respectively, making them fit tightly against the inner wall of the self-locking groove 204, thereby locking the position of the extension ruler 201. At the same time, the two hooks 212 of the limiting rod 211 are rotated, and the hooks are hooked on the arc surface of the limiting frame 210 to maintain the position of the mounting post 208, further maintaining the position of the extension ruler 201 after extension and preventing it from sliding accidentally. After the track ruler extension and fixing are completed, the display 7 and the laser rangefinder 6 are operated by controlling the microcontroller 9. First, the laser rangefinder 6 starts to work. Before the track ruler is extended, the laser rangefinder... The distance between the laser rangefinder 6 and the detection plate 11 is recorded as zero. When the track gauge is extended, the laser rangefinder 6 emits a laser to detect the distance between itself and the detection plate 11. The laser rangefinder 6 transmits the measurement data to the microcontroller 9. After receiving the data, the microcontroller 9 performs calculations based on the fixed detection values ​​of the track gauge itself (such as the distance between the probe 3 and the moving probe 4 at the initial position and other related fixed values) to finally obtain the track gauge data of the current track. Then, the microcontroller 9 transmits the processed track gauge data to the display 7. Finally, the display 7 displays the track gauge value intuitively for easy reading by the staff.

[0027] It is worth noting that the battery 5 disclosed in the above embodiments can be a CR2032 type lithium manganese battery, the laser rangefinder 6 can be a VL53L0X type, the display 7 can be a 12864 LCD screen, and the microcontroller 9 can be an STC89C52 type. The microcontroller 9 controls the operation of the laser rangefinder 6 and the display 7 using methods commonly used in the prior art.
