Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of anti-derailment devices, specifically an anti-derailment device for a track inspection vehicle. Background Technology
[0002] A track inspection trolley is a specialized device used for track inspection, primarily to detect the track's geometry, damage, stress distribution, etc., to ensure safe train operation. Depending on the inspection requirements and functions, there are several common types of track inspection trolleys, such as laser displacement sensor trolleys, which employ laser ranging technology and feature high precision and fast response, suitable for accurate measurement of track length; and track geometry trolleys, which monitor the track's straightness, torsion, and other geometric conditions in real time to ensure safe train operation. Track damage detection trolley: Utilizes ultrasonic and infrared technologies to detect track cracks, wear, and other damage. Track stress trolley: Monitors track stress distribution in real time, providing a basis for track maintenance. Track inspection robot: Integrates multiple detection devices to achieve comprehensive, multi-angle track inspection, improving inspection efficiency. These trolleys play a crucial role in the rail transit field and are applicable to various rail transit systems such as subways, railways, and trams. When using track inspection trolleys for track inspection, anti-derailment devices need to be installed to ensure stable operation. Existing anti-derailment devices for track inspection trolleys mostly rely on magnetic adsorption to prevent derailment. By creating a strong magnetic field between the wheel and the rail, the wheel adheres tightly to the rail, increasing the contact area and enhancing wheel stability. However, traditional anti-derailment devices for track inspection trolleys, relying on magnetic adsorption, lack rigid limiting, leaving the track inspection trolley at risk of derailment. Therefore, we propose an anti-derailment device for track inspection trolleys. Utility Model Content

[0011] Furthermore, pulleys are rotatably connected to the side of the deflection plate and the limiting plate away from the center of the mounting shell. The outer edges of the pulleys are fitted to the outer surface of the vertically adjacent track to reduce the friction between the deflection plate and the limiting plate and the track.
[0012] Furthermore, it also includes a microcontroller, which is located in the middle of the front side of the track trolley. The microcontroller is bidirectionally electrically connected to the track trolley, providing control for the track's anti-derailment operation.

The input terminal of the microcontroller 7 is electrically connected to the output terminal of the battery, and the output terminal of the microcontroller 7 is electrically connected to the input terminal of the drive device. The microcontroller 7 provides control for the anti-derailment operation of the track 1.
[0023] Anti-derailment mechanism 6: It includes a movable plate 61, a rack plate 62, gears 63, a deflection plate 64, and a limiting component 65. The movable plate 61 is slidably connected to the front and rear sides of the slide groove 4. The rack plates 62 are respectively disposed on the left and right sides of the movable plate 61. The gears 63 are respectively rotatably connected to the left and right sides of the slide groove 4. The rack plates 62 are all meshed with the vertically adjacent gears 63. The deflection plates 64 are all disposed on the outer surface of the gears 63, providing a basis for the anti-derailment operation inside the track 1. The limiting component 65 is disposed inside the slide groove 5. Each side is equipped with a sliding column, the outer surface of which is slidably connected to the inner center of the moving plate 61, making the sliding of the moving plate 61 more stable. The limiting assembly 65 includes a limiting plate 651, a limiting groove 652, and a limiting post 653. The limiting plates 651 are all slidably connected to the inside of the sliding groove 5. The limiting grooves 652 are all opened in the inner center of the limiting plates 651. The limiting posts 653 are all set on the left and right sides of the upper end of the moving plate 61. The limiting grooves 652 are all installed in conjunction with the vertically adjacent limiting posts 653, providing a basis for the anti-derailment work on the outside of the track 1. The limiting grooves 652 are close to the mounting shell. One side of the middle section of the 3-section is deflected outwards. The inner wall of the limiting groove 652 is slidably connected to the upper end of the outer surface of the vertically adjacent limiting post 653, providing a basis for the movement of the limiting plate 651. The anti-derailment mechanism 6 also includes a bidirectional lead screw 66 and a motor 67. The bidirectional lead screw 66 is rotatably connected to the middle of the interior of the slide groove 4. The outer surface of the bidirectional lead screw 66 is threaded to the inner center of the moving plate 61. The motor 67 is located in the middle of the front side of the mounting housing 3. The input end of the motor 67 is electrically connected to the output end of the microcontroller 7. The rear end of the output shaft of the motor 67 is fixedly connected to the front end of the bidirectional lead screw 66. Next, to provide stable drive for the anti-derailment operation of track 1, pulleys 68 are rotatably connected to the side of the deflection plate 64 and the limiting plate 651 away from the center of the mounting shell 3. The outer edge of the pulleys 68 is installed in conjunction with the outer surface of the vertically adjacent track 1 to reduce the friction between the deflection plate 64 and the limiting plate 651 and the track 1. The anti-derailment mechanism 6 is provided, which can simultaneously extend and retract two levels of rigid limiting structure. The synchronous limiting of the two levels of rigid limiting structure forms a limiting effect on the track inspection vehicle, thereby achieving the purpose of preventing the track inspection vehicle from derailing and improving the anti-derailment performance of the track inspection vehicle.
[0024] The working principle of the anti-derailment device for a track inspection vehicle provided by this utility model is as follows: When performing anti-derailment work on the track inspection vehicle, the track trolley 2 is placed above two tracks 1. The microcontroller 7 controls the motor 67 to operate. The output shaft of the motor 67 drives the bidirectional lead screw 66 to rotate. Because the outer surface of the bidirectional lead screw 66 is threadedly connected to the inner center of the moving plate 61, the two moving plates 61 move outward accordingly. The rack plate 62 also moves accordingly. Because the rack plate 62 is meshed with the vertically adjacent gear 63, the gear 63 rotates as the rack plate 62 moves, driving the deflection plate 64 to deflect outward until all four deflection plates 64 deflect outward by ninety degrees. At this time, the outer edge of the pulley 68 at the outer end of the deflection plate 64 contacts the inner top wall of the corresponding track 1, and the track inspection vehicle and the inner side of the track 1 form an anti-derailment effect. At the same time, as the moving plate 61 moves outward, the limiting post 653 also moves outward. The outer surface of the limiting post 653 presses against the inner wall of the corresponding limiting groove 652, and the limiting groove 652 moves inward. The limiting plate 651 also moves inward until the outer edge of the pulley 68 at the outer end of the limiting plate 651 contacts the outer top wall of the corresponding track 1. At this time, the track inspection vehicle and the outer side of the track 1 form an anti-derailment effect. Both the inner and outer sides of the track 1 and the track inspection vehicle form an anti-derailment effect. The rigid limiting structure makes the anti-derailment effect better.
[0025] It is worth noting that the microcontroller 7 disclosed in the above embodiments is an S7-200 microcontroller, the track trolley 2 is a KP-2T track trolley, and the motor 67 is an M5RK-40C / 5GU-7.5RT motor.
