Description

Technical Field

[0001] This utility model relates to the field of track measurement, and in particular to a guide rail gauge measuring device. Background Technology

[0002] Measuring track gauge is one of the core tasks of railway track maintenance. A uniform track gauge can prevent severe vibrations caused by lateral deformation of the track when a train passes, thereby protecting track fasteners, sleepers, and roadbed structures and extending their service life. Most existing track gauge measuring devices use telescopic structures to measure the guide rails. During the measurement process, manual adjustment is required to adapt to the size of the guide rail. When facing different guide rails, it is not possible to adjust quickly and accurately, which reduces measurement efficiency and is prone to slight deviations. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a guide rail gauge measuring device.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A guide rail gauge measuring device includes a detection frame, a drive motor fixedly connected to the bottom of the detection frame, a detection adjustment component provided at the top of the transmission rod of the drive motor, the detection adjustment component including a drive gear, a right-side rack and a left-side rack meshing with the outer surface of the drive gear, a sliding stabilizing block fixedly connected to the center of each of the right-side rack and the left-side rack, a connecting block fixedly connected to the opposite end of each of the left-side rack and the right-side rack, a fixed base fixedly connected to the side of the connecting block near the drive gear, a distance sensor fixedly connected to the top of the fixed base, and a contact pushing component provided at the bottom of the distance sensor.

[0005] As a preferred technical solution of this utility model, the bonding and pushing component includes a squeezing chamber, a squeezing spring is provided inside the squeezing chamber, the top end of the squeezing spring is fixedly connected to the squeezing chamber, the bottom end of the squeezing spring is movably connected to a measuring ruler, two fixed frames are fixedly connected to the outer surface of the squeezing chamber, a rubber roller is movably connected between the two fixed frames, a dirt removal component is provided on the side of the rubber roller away from the fixed frame, a support frame is provided on the side of the rubber roller away from the fixed frame, the top end of the support frame is fixedly connected to a detection frame, and an auxiliary roller is movably connected between the support frame and the detection frame.

[0006] As a preferred technical solution of this utility model, the decontamination component includes two linkage arms. The side of the linkage arm closer to the rubber roller is fixedly connected to a distance sensor, and the side of the linkage arm away from the distance sensor is fixedly connected to a drive arm. A cleaning scraper is fixedly connected to the bottom of the drive arm, and a sliding block is fixedly connected to the center of the drive arm. A rectangular sliding groove is provided on the outer surface of the detection frame, and the sliding block is slidably connected to the detection frame through the rectangular sliding groove.

[0007] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0008] 1. This utility model transforms the rotational motion of a single motor into a left-right symmetrical linear motion through gear and rack transmission, enabling the left and right racks, distance sensors, and cleaning components to unfold synchronously and accurately. This allows for a multi-task process of automatic track gauge calibration, cleaning, and height detection after one-button start, significantly shortening on-site debugging time. Furthermore, the mechanical limit design of the rectangular slide and linkage arm reduces the risk of misoperation, making it suitable for non-professionals to quickly get started.

[0009] 2. This utility model adopts an elastic structure that links the compression spring and the measuring ruler, combined with a dual support system of rubber rollers and auxiliary rollers, so that the equipment can adapt to tracks with different heights and wear levels. When there is local deformation or slope change of the track, the spring in the compression chamber can be compressed and buffered to ensure that the sensor is always vertically aligned with the detection surface. The roller group reduces the travel resistance through flexible contact, making manual pushing easier and avoiding slippage. It is suitable for continuous detection operations on old lines or complex terrain.

[0010] 3. This utility model uses a drive motor to link a rack and pinion mechanism, which enables the cleaning scraper to automatically adhere to the inner wall of the track and remove the attached substances during the detection process. This avoids the cumbersome process of manually cleaning before measurement, reduces the interference of attached substances on sensor data, and extends the service life of the track contact surface through timely cleaning.

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0018] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a detection frame 1. A drive motor 2 is fixedly connected to the bottom of the detection frame 1. The drive motor 2 is a Mingzhi NEMA6 standard hybrid stepper motor. A detection adjustment assembly is provided at the top of the transmission rod of the drive motor 2. The detection adjustment assembly includes a drive gear 3. A right rack 4 and a left rack 5 are meshed on the outer surface of the drive gear 3. A sliding stabilizing block 6 is fixedly connected to the center of both the right rack 4 and the left rack 5. A connecting block 7 is fixedly connected to the opposite end of both the left rack 5 and the right rack 4. A fixed base 8 is fixedly connected to the side of the connecting block 7 near the drive gear 3. A distance sensor 9 is fixedly connected to the top of the fixed base 8. The distance sensor 9 is a Keyence LJ-X series. A contact pushing assembly is provided at the bottom of the distance sensor 9.

[0019] When the equipment is inspecting a section of track, the inspector places the equipment on the track, starts the equipment, and the distance sensor 9 detects the track distance. After the distance sensor 9 completes the detection, it drives the drive motor 2 to rotate. The clockwise rotation of the drive motor 2 drives the drive gear 3 to rotate clockwise. The clockwise rotation of the drive gear 3 drives the right rack 4 and the left rack 5 to move linearly in opposite directions. The linear movement of the right rack 4 and the left rack 5 drives the bonding and pushing component to adhere to the inner wall of the track. When the bonding and pushing component adheres to the inner wall of the track, the inspector pushes the track, and the distance sensor 9 detects the track gauge of a section of track.

[0020] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the bonding and pushing assembly includes a squeezing chamber 10, inside which a squeezing spring 11 is provided. The top end of the squeezing spring 11 is fixedly connected to the squeezing chamber 10, and the bottom end of the squeezing spring 11 is movably connected to a measuring ruler 12. Two fixed frames 13 are fixedly connected to the outer surface of the squeezing chamber 10, and a rubber roller 14 is movably connected between the two fixed frames 13. A cleaning component is provided on the side of the rubber roller 14 away from the fixed frame 13, and a support frame 20 is provided on the side of the rubber roller 14 away from the fixed frame 13. The top end of the support frame 20 is fixedly connected to a detection frame 1, and an auxiliary roller 21 is movably connected between the support frame 20 and the detection frame 1.

[0021] When the bonding and pushing component is pressed against the inner wall of the track, the ground presses against the measuring ruler 12. After being pressed, the measuring ruler 12 moves upward, which in turn presses against the compression spring 11, thereby detecting the height of the guide rail. At the same time, the rubber roller 14 and the auxiliary roller 21 cooperate to press against both sides of the guide rail. When the inspector pushes the equipment, the rubber roller 14 and the auxiliary roller 21 rotate along the guide rail wall, thereby driving the equipment to perform forward or backward detection.

[0022] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the cleaning assembly includes two linkage arms 15. The side of the linkage arm 15 closest to the rubber roller 14 is fixedly connected to the distance sensor 9, and the side of the linkage arm 15 furthest from the distance sensor 9 is fixedly connected to the drive arm 16. A cleaning scraper 17 is fixedly connected to the bottom of the drive arm 16, and a sliding block 18 is fixedly connected to the center of the drive arm 16. A rectangular sliding groove 19 is provided on the outer surface of the detection frame 1, and the sliding block 18 is slidably connected to the detection frame 1 through the rectangular sliding groove 19.

[0023] When the inspector pushes the equipment to inspect the guide rail, the relative linear motion of the right rack 4 and the left rack 5 causes the two cleaning components to come into contact with the inner wall of the rail. The relative motion of the right rack 4 and the left rack 5 causes the two linkage arms 15 to move in a relative linear motion. The relative linear motion of the two linkage arms 15 causes the two drive arms 16 and the cleaning scraper 17 to move in a relative linear motion. The two cleaning scrapers 17 move in a relative linear motion to come into contact with the inner wall of the guide rail. The scraper is installed on the side of the two cleaning scrapers 17 closest to the inner wall of the guide rail. With the pushing force of the inspector, the scraper on the cleaning scraper 17 cleans the deposits on the inner wall, avoiding the decrease in inspection accuracy caused by the deposits, and also improving the service life of the rail.

[0024] Working principle:

[0025] Please refer to Figures 1-5As shown, when the equipment is inspecting a section of track, the inspector places the equipment on the track, starts the equipment, and the distance sensor 9 detects the track distance. After the distance sensor 9 completes the detection, it drives the drive motor 2 to rotate. The clockwise rotation of the drive motor 2 drives the drive gear 3 to rotate clockwise. The clockwise rotation of the drive gear 3 drives the right rack 4 and the left rack 5 to move linearly in opposite directions. The linear movement of the right rack 4 and the left rack 5 drives the bonding and pushing component to adhere to the inner wall of the track. When the bonding and pushing component adheres to the inner wall of the track, the inspector pushes the track, and the distance sensor 9 detects the track gauge of a section of track.

[0026] When the bonding and pushing component is pressed against the inner wall of the track, the ground presses against the measuring ruler 12. After being pressed, the measuring ruler 12 moves upward, which in turn presses against the compression spring 11, thereby detecting the height of the guide rail. At the same time, the rubber roller 14 and the auxiliary roller 21 cooperate to press against both sides of the guide rail. When the inspector pushes the equipment, the rubber roller 14 and the auxiliary roller 21 rotate along the guide rail wall, thereby driving the equipment to perform forward or backward detection.

[0027] When the inspector pushes the equipment to inspect the guide rail, the relative linear motion of the right rack 4 and the left rack 5 causes the two cleaning components to come into contact with the inner wall of the rail. The relative motion of the right rack 4 and the left rack 5 causes the two linkage arms 15 to move in a relative linear motion. The relative linear motion of the two linkage arms 15 causes the two drive arms 16 and the cleaning scraper 17 to move in a relative linear motion. The two cleaning scrapers 17 move in a relative linear motion to come into contact with the inner wall of the guide rail. The scraper is installed on the side of the two cleaning scrapers 17 closest to the inner wall of the guide rail. With the pushing force of the inspector, the scraper on the cleaning scraper 17 cleans the deposits on the inner wall, avoiding the decrease in inspection accuracy caused by the deposits, and also improving the service life of the rail.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
