Description

Technical Field

[0001] The utility model relates to the technical field of railway engineering, and particularly relates to a track gauge adjusting device for railway engineering. Background Technique

[0002] With the continuous development of social economy, trains account for an increasingly large proportion in our daily travel. Therefore, it is crucial to ensure the laying and maintenance standards of tracks. How to ensure the safe, efficient and stable operation of tracks is a major issue. Due to the large weight of the train body and the large number of train trips, the tracks are in a state of high load and high impact for a long time. Coupled with the changes in ballast and the surrounding environment, various factors will cause changes in the track gauge. One of the prerequisite conditions for the safe operation of the track is to ensure that the track gauge is always within a reasonable range. After the track is used for a long time, deviations will inevitably occur, and a track gauge adjusting device is needed to process the deviated track.

[0003] For example, a track gauge adjusting device for railway engineering with the Chinese patent application number CN202222558307.6, which relates to the technical field of railway engineering, includes a walking mounting plate. Guide plates are fixedly installed on both sides of the bottom of the walking mounting plate. Distance measuring mechanisms are installed on both sides of the walking mounting plate and one side of the guide plates. The distance measuring mechanism includes a mounting rod. An installation groove is formed inside the mounting rod. A measuring rod is movably installed inside the installation groove. A spring is sleeved outside the measuring rod. Through the cooperation of the mounting rod, the installation groove, the measuring rod, the spring, the push plate, the sliding groove, the sliding rod, the measuring wheel, the marking head and the measuring scale, when walking, the measuring wheel can be in contact with both sides of the railway track. When the railway track deviates, the measuring wheel contacts the railway track and deviates, and then the measuring rod is pushed to move through the sliding rod and the push plate. The actual distance of the deviation of the railway track can be visually observed through the cooperation of the marking head and the measuring scale, so as to more conveniently adjust the actual distance during gauge adjustment.

[0004] The above device measures the track gauge through measuring tools such as a marking head and a measuring scale. However, when there is a deviation in the measured value, it is not convenient to automatically adjust the distance between the tracks, and the subsequent operation is not convenient, time-consuming and laborious.

[0025] As Figures 1-5 shown, the present invention provides a railway engineering track gauge adjustment device, including a U-shaped chassis 1, and side fixed frames 3 are arranged on both sides of the U-shaped chassis 1;

[0026] As Figures 1-4As shown in the figure, a distance adjustment component 2 is provided on the top of the U-shaped chassis 1, which is used to automatically measure the distance between railway engineering tracks. After the distance measurement is completed, it is convenient to automatically adjust the track distance. The distance adjustment component 2 includes a driving frame 21, which is arranged on the top of the U-shaped chassis 1. Two rectangular slots are opened at the bottom of the driving frame 21. Between the two ends inside the two rectangular slots, threaded rods 22 are connected through bearings. A rectangular block 23 in contact with the rectangular slot is threadedly connected to the threaded rod 22. A distance adjustment frame 25 is fixedly arranged at the bottom of the rectangular block 23. On one side of the top of the two side fixed frames 3 away from the driving frame 21, vertical plates 6 are fixedly arranged respectively. A laser displacement sensor 28 and a light plate 27 for opposed light are fixedly arranged on the sides of the two vertical plates 6 close to each other. T-shaped sliding grooves 26 are opened at the bottoms of the two distance adjustment frames 25. T-shaped sliders are fixedly arranged at both ends of the U-shaped chassis 1. The two T-shaped sliders are respectively slidably arranged in the two T-shaped sliding grooves 26, which is convenient for the distance adjustment frame 25 to move along both sides of the U-shaped chassis 1.

[0027] As Figures 1-4 shown in the figure, a controller is fixedly arranged on the top of the driving frame 21. Motors 24 are fixedly arranged in the inner walls on both sides of the driving frame 21. The two ends of the two threaded rods 22 away from each other respectively penetrate through the side walls on both sides of the driving frame 21 and are fixedly connected to the output shafts of the motors 24, which is convenient for the motors 24 to drive the driving frame 21 to rotate. The motors 24 are fixedly connected to the output end of the controller, and the laser displacement sensor 28 is connected to the input end of the controller. The side fixed frame 3 is fixedly arranged on the side of the distance adjustment frame 25 away from the U-shaped chassis 1. Rollers 4 are arranged between the inner side walls on both sides of the side fixed frame 3 through a rotating shaft. Two limit wheels 5 distributed front and back are inlaid at the bottoms of the two side walls of the side fixed frame 3, which is convenient to clamp the side fixed frame 3 on the top of the railway engineering track and move along the track.

[0028] As Figure 1 、 2 As shown in Figures 5, fixed plates 7 are fixedly arranged between the front and rear side walls of the driving frame 21 and the front and rear side walls of the U-shaped chassis 1. A telescopic rod 8 is fixedly arranged at the bottom of the fixed plate 7. A support frame 9 is fixedly arranged at the bottom of the telescopic rod 8, which is convenient to adjust the height of the telescopic rod 8 to drive the support frame 9 to move up and down. An electric vehicle wheel 10 is arranged inside the support frame 9, and the electric vehicle wheel 10 is connected to the output end of the controller, which is convenient for the utility model to move along the center of the railway engineering track.

[0029] By setting the distance adjustment component 2, the staff places the present utility model on the subway engineering track that needs distance adjustment, and then adjusts the heights of the two telescopic rods 8 according to the height of the track, so as to facilitate clamping the two side fixing frames 3 to the tops of the two sides of the track. At the same time, the rollers 4 inside the side fixing frame 3 are placed on the top of the track, and the limiting wheels 5 are clamped to the outer wall of the track, thereby clamping the side fixing frame 3 to the track, making the electric vehicle wheels 10 placed in the middle of the track. Then, operate the two electric vehicle wheels 10 to start moving. The electric vehicle wheels 10 drive the two side fixing frames 3 to move along the track. During the movement, the laser displacement sensor 28 emits laser light and transmits it to the opposed light plate 27 to detect whether there is a deviation in the gauge between the tracks (the working principle of the laser emitter is: the visible red laser is emitted onto the surface of the object through the lens, the laser reflected by the object passes through the receiver lens and is received by the internal CCD linear camera. According to different distances, the CCD linear camera can "see" this light spot at different angles. According to this angle, the distance between the laser and the camera can be known, and the digital signal processor can calculate the distance between the sensor and the measured object);

[0030] After the laser displacement sensor 28 detects that there is a deviation in the gauge between the tracks, the laser displacement sensor 28 sends a signal to the controller on the top of the drive frame 21. The controller then controls the motor 24 to work and drive the threaded rod 22 to rotate. The rotation of the threaded rod 22 drives the rectangular block 23 on it to move horizontally along the threaded rod 22. At the same time, the rectangular block 23 is arranged inside the rectangular slot, which is convenient for limiting the movement of the rectangular block 23, so that the two distance adjustment frames 25 approach or move away from each other along the top of the U-shaped chassis 1, and at the same time drive the two side fixing frames 3 to approach or move away from each other and drive the track to shift, thereby facilitating automatic distance adjustment between the tracks, ensuring the timeliness of the distance adjustment of the subway engineering track, and the operation is convenient.
