[0007] Preferably, a visual recognition mechanism is provided on one side of the electric crawler, and the visual recognition mechanism includes a steering ball, and the steering ball is rotatably connected to one side of the electric crawler. There are two steering balls, and a telescopic rod is fixedly connected between the two steering balls.

[0009] Preferably, a one-way valve and a fine air hole are provided on the outer wall of the telescopic rod, the interior of the telescopic rod is connected with the fine air hole and the interior of the vent pipe, the air inlet end of the one-way valve is connected with the outside of the telescopic rod, and the air outlet end of the one-way valve is connected with the inside of the telescopic rod.

[0010] Preferably, one side of the vertical plate is fixedly connected to a connecting block, one side of the connecting block is fixedly connected to bristles, one end of the bristles contacts one side of the rail, one side of the push plate is slidably connected to a circular sleeve, the inner wall of the circular sleeve is fixedly connected to the outer wall of the telescopic rod, and the outer wall of the telescopic rod is fixedly connected to a scale ring.

[0011] Preferably, the inner wall of the vertical plate is provided with an auxiliary identification mechanism, and the auxiliary identification mechanism includes a vertical rod, the inner wall of the vertical plate is fixedly connected to both ends of the vertical rod, the outer wall of the vertical rod is slidably connected to a lifting block, the outer wall of the lifting block is fixedly connected to a block, the top of the lifting block is fixedly connected to a thin spring, and one end of the thin spring is fixedly connected to the top of the inner wall of the steering ball.

[0012] The present invention provides a portable laser rail creep measuring instrument. It has the following beneficial effects: 1. The present invention provides a creeping measurement mechanism, and one side of the sliding block contacts the rail through a rolling ball, thereby achieving a portable quick clamping effect and reducing the friction during the mobile detection process. This quick clamping method avoids the problem of easy falling off when magnetically attached to the rail. The inverted tooth shape formed by the sliding block and the inclined plate can ensure convenient installation and more stable clamping on the rail, and will not cause the problem of unstable detection state due to vibration generated during subsequent movement.

[0013] 2. The present invention provides a visual recognition mechanism. When the left and right electric crawlers move synchronously on the rails, even if the rails are uneven, the rotation of the steering ball allows the telescopic rod to freely change its angle, ensuring that the two electric crawlers can complete synchronous movement while avoiding getting stuck on the rails, thus ensuring stable detection of the two electric crawlers moving synchronously. 3. The present invention provides a visual recognition mechanism. Once there is an angular deviation or height difference in the rails, the position of the laser transmitter on the laser receiver will also be offset. The laser receiver can record the point information of the laser reception in real time and send it to the cloud for analysis and research by the rear staff. It can also be analyzed together with the data detected by the optical measuring device at the same time, so that the relative positions of the two rails can be detected at the same time without interfering with each other. While improving work efficiency, it also increases more detection data, facilitating subsequent maintenance and inspection of the rails.

[0014] 4. The present invention provides a visual recognition mechanism to squeeze the air into the telescopic plate, which is smaller than the amount of air in the telescopic plate that is pushed back into the telescopic rod by the gravity of the vertical plate and discharged through the fine air holes. As a result, the vertical plate remains in a hanging state. Then, by observing the state of the vertical plate in real time, it can be quickly determined whether there are a large number of unevenness and angular deviations in the corresponding positions of the two rails, so that the staff can conduct a quick preliminary investigation, thereby improving the multi-directional detection method of the rails and improving the detection efficiency. 5. The present invention provides a visual recognition mechanism. The lifting of the vertical plate will cause the vertical plate to vibrate to a certain extent. The vibration will cause the bristles on the connecting block on one side of the vertical plate to vibrate synchronously. When the bristles are in contact with the surface of the rail and sweep with the movement of the electric crawler, the vibration of the vertical plate can also enhance the effect of the bristles in pushing down particles on the surface of the rail. At the same time, it can also generate elastic vibration on the bristles, cooperate with the detection process to complete the self-cleaning effect of the vibration, ensure long-term and stable cleaning effect on the rail surface, and make the optical detection of the rail by the optical measuring instrument more accurate and stable.

[0015] 6. The present invention provides an auxiliary identification mechanism, so that the staff can more quickly judge the approximate position of the vertical plate lifting by observing the position of the lifting block and the square. At the same time, the specific angle of the vertical plate lifting can be specifically judged by the specific scale position on the scale ring, completing the distinction between rough and quick judgment and precise identification, which is convenient for obtaining different information according to different scene conditions.

DETAILED DESCRIPTION

[0018] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a portable laser rail creep measuring instrument, comprising a base 1, a rail 2 is arranged on the top of the base 1, and a creep measuring mechanism 3 is arranged on the top of the rail 2; The creep measurement mechanism 3 includes: The electric crawler 301 is a square block structure. A groove 302 is formed on the inner wall of the electric crawler 301. A rolling wheel 303 is provided on the inner wall of the electric crawler 301. An optical measuring device 304 is provided at the bottom of the electric crawler 301. The electric crawler 301 is used to run on the rail 2 and utilize the optical measuring device 304 to perform dynamic detection of the rail 2. The fixed frame 305 is a frame-shaped structure. The inner wall of the fixed frame 305 is slidably connected to a sliding block 306. The bottom of the sliding block 306 is fixedly connected to an inclined plate 307. A rolling ball 308 is embedded on one side of the sliding block 306. A spring 309 is provided inside the fixed frame 305.

[0019] One end of the spring 309 is fixedly connected to the inner wall of the fixed frame 305 , and the other end of the spring 309 is fixedly connected to one side of the sliding block 306 .

[0020] There are two electric crawlers 301. The right side of the electric crawler 301 on the left is fixedly connected to a laser transmitter 310, and the left side of the electric crawler 301 on the right is fixedly connected to a laser receiver 311. When in use, the electric crawler 301 is placed on the rail 2, and the inclined plate 307 at the bottom of the electric crawler 301 contacts the top of the rail 2, and as the electric crawler 301 is pressed, the inclined surface at the bottom of the inclined plate 307 will be pressed against the top of the rail 2 and move toward the spring 309, and the spring 309 is squeezed to deform it. After the spring 309 is deformed, the sliding block 306 slides to the inner wall of the fixed frame 305, and the two inclined plates 307 at the bottom of the electric crawler 301 move away from each other until the inclined plate 307 moves to the lower depression of the rail 2. At this time, the sliding block 306 is subjected to the elastic force of the spring 309, and the sliding block 306 pops out, so that the sliding block 306 begins to stick to the lower depression of the rail 2. The electric crawler 301 is started to control the rotation of the rolling wheel 303, so that the electric crawler 301 is clamped on the rail 2 and slides automatically. The optical measuring device 304 is used to complete the movement detection of the rail 2. At the same time, one side of the sliding block 306 contacts the rail through the rolling ball 308, realizing a portable and rapid clamping effect, and also reducing the friction during the movement detection process. This rapid clamping method avoids the problem of easy falling off of the rail 2 by magnetic attraction. The inverted tooth shape formed by the sliding block 306 and the inclined plate 307 can ensure convenient installation and more stable clamping on the rail 2, and will not cause the problem of unstable detection state due to vibration generated during subsequent movement. Example 2: Please refer to Figure 1-8Based on the first embodiment, the present invention provides a technical solution: a visual recognition mechanism 4 is provided on one side of the electric crawler 301, and the visual recognition mechanism 4 includes a steering ball 401, which is rotatably connected to one side of the electric crawler 301. There are two steering balls 401, and a telescopic rod 402 is fixedly connected between the two steering balls 401.

[0021] A ventilation pipe 404 is fixedly connected to the outer wall of the telescopic rod 402, one end of the ventilation pipe 404 is fixedly connected to a fixing bar 405, one side of the fixing bar 405 is fixedly connected to the outer wall of the telescopic rod 402, one side of the fixing bar 405 is fixedly connected to a telescopic plate 406, one end of the telescopic plate 406 is fixedly connected to a push plate 407, and the bottom of the push plate 407 is fixedly connected to a vertical plate 408.

[0022] A one-way valve 409 and a fine air hole 410 are provided on the outer wall of the telescopic rod 402. The interior of the telescopic rod 402 is connected to the fine air hole 410 and the interior of the vent pipe 404. The air inlet end of the one-way valve 409 is connected to the outside of the telescopic rod 402, and the air outlet end of the one-way valve 409 is connected to the inside of the telescopic rod 402.

[0023] A connecting block 411 is fixedly connected to one side of the vertical plate 408, a brush 412 is fixedly connected to one side of the connecting block 411, one end of the brush 412 contacts one side of the rail 2, a circular sleeve 414 is slidably connected to one side of the push plate 407, the inner wall of the circular sleeve 414 is fixedly connected to the outer wall of the telescopic rod 402, and a scale ring 413 is fixedly connected to the outer wall of the telescopic rod 402; After the left and right electric crawlers 301 are installed on the rail 2, the two electric crawlers 301 are connected to the telescopic rod 402 via the steering ball 401. The steering ball 401 allows the telescopic rod 402 to freely change its angle. Therefore, when the left and right electric crawlers 301 move synchronously on the rail 2 at the same time, if the rail is uneven, the rotation of the steering ball 401 can allow the telescopic rod 402 to freely change its angle, thereby ensuring that the two electric crawlers 301 can complete the synchronous movement and avoid getting stuck on the rail 2, thereby ensuring stable detection work under the synchronous movement of the two electric crawlers 301; When the two electric crawlers 301 move synchronously, the laser transmitter 310 on the left electric crawler 301 can send laser light to the laser receiver 311 on the right electric crawler 301 in real time. If the two electric crawlers 301 are kept horizontal and facing each other, the laser point emitted by the laser transmitter 310 is the center position of the laser receiver 311. Once there is an angular deviation or height difference between the rails 2, the position of the laser transmitter 310 emitted to the laser receiver 311 will also be offset. The laser receiver 311 can record the point information of the received laser light in real time and send it to the cloud for the rear staff to analyze and study the recorded data. It can also be analyzed together with the data detected by the optical measuring device 304 at the same time, so that the relative positions of the two rails 2 can be detected at the same time without interfering with each other, thereby improving work efficiency and increasing more detection data, which is convenient for subsequent maintenance and inspection of the rails 2. When the two electric crawlers 301 are moving and detecting, the position movement caused by the difference in height and angle offset of the rail 2 will be reflected by the angle change of the telescopic rod 402. Whenever there is a height change, the angle of the telescopic rod 402 will change. At the same time, the positions of the two steering balls 401 are limited between the two electric crawlers 301. Therefore, when the angle of the telescopic rod 402 changes, the straight-line distance between the two steering balls 401 also changes, so that the length of the telescopic rod 402 will also be extended or shortened. Because the outer wall of the telescopic rod 402 is provided with a one-way valve 409 and a fine air hole 410, the diameter of the one-way valve 409 is much larger than the fine air hole 410. When the telescopic rod 402 is extended, air is taken in through the one-way valve 409. When the telescopic rod 402 is shortened, the air on its inner wall is squeezed. The squeezed air on the inner wall of the telescopic rod 402 enters the fixed bar 4 through the vent pipe 404. 05 and the telescopic plate 406, the diameter of the vent 404 is much larger than the fine air hole 410, so the air will quickly enter the telescopic plate 406, causing the telescopic plate 406 to slide and extend, and push the push plate 407 and the vertical plate 408 to slide on the outer wall of the circular sleeve 414, and the vertical plate 408 is in a lifted state. Once the vertical plate 408 is lifted, it will squeeze the telescopic plate 406 with its own gravity to reset it, and the air inside the telescopic plate 406 will also flow back. Air enters the telescopic rod 402 through the vent pipe 404. The one-way valve 409 is a one-way air intake valve, so the air can only be discharged through the fine air hole 410. However, due to the small diameter of the fine air hole 410, when the telescopic rod 402 frequently extends and contracts, the exhaust speed of the fine air hole 410 is limited. A large amount of air is drawn into the telescopic rod 402 by the one-way valve 409 and squeezed into the telescopic plate 406, pushing the vertical plate 408 to continuously rise. When the telescopic rod 402 is extended and retracted at a low frequency, air is not squeezed frequently. Then, the amount of air squeezed into the telescopic plate 406 is less than the amount of air in the telescopic plate 406 that is pushed back into the telescopic rod 402 by the gravity of the vertical plate 408 and discharged through the fine air holes 410. As a result, the vertical plate 408 remains in a hanging state. Then, by observing the state of the vertical plate 408 in real time, it is possible to quickly determine whether there are a large number of unevenness and angle deviation problems at the corresponding positions of the two rails 2, so that the staff can quickly conduct preliminary inspections, thereby improving the multi-directional detection method of the rails 2 and improving the detection efficiency. During the extension and retraction of the telescopic rod 402, the vertical plate 408 will be continuously and rapidly lifted. The lifting of the vertical plate 408 will cause the vertical plate 408 to vibrate to a certain extent. The vibration will cause the bristles 412 on the connecting block 411 on one side of the vertical plate 408 to vibrate synchronously. When the bristles 412 come into contact with the surface of the rail 2 and move and sweep along with the electric crawler 301, the vibration of the vertical plate 408 can also enhance the effect of the bristles 412 in pushing away particles on the surface of the rail 2. At the same time, it can also generate elastic vibration for the bristles 412, and cooperate with the detection process to complete the self-cleaning effect of the vibration, thereby ensuring a long-term and stable cleaning effect on the surface of the rail 2, making the optical detection of the rail 2 by the optical measuring device 304 more accurate and stable. Example 3: Please refer to Figure 1-13 On the basis of the first and second embodiments, the present invention provides a technical solution: an auxiliary identification mechanism 5 is provided on the inner wall of the vertical plate 408, and the auxiliary identification mechanism 5 includes a vertical rod 501. The inner wall of the vertical plate 408 is fixedly connected to both ends of the vertical rod 501. A lifting block 503 is slidably connected to the outer wall of the vertical rod 501. A block 504 is fixedly connected to the outer wall of the lifting block 503. A fine spring 502 is fixedly connected to the top of the lifting block 503. One end of the fine spring 502 is fixedly connected to the top of the inner wall of the steering ball 401. Once the vertical plate 408 gradually rises, the lifting block 503 and the block 504 in the steering ball 401 on the inner wall of the vertical plate 408 will be supported by the tilted inner wall of the steering ball 401, so that the elastic force of the thin spring 502 will pull the lifting block 503 and the block 504 upward, and the lifting block 503 will drive the block 504 to move on the vertical rod 501. The staff can more quickly judge the approximate position of the lifting of the vertical plate 408 by observing the positions of the lifting block 503 and the block 504. At the same time, the specific angle of the lifting of the vertical plate 408 can be judged by the specific scale position on the scale ring 413, so as to distinguish between rough and fast judgment and precise identification, so as to obtain different information according to different scene conditions.

[0024] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
