Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of railway maintenance, in particular to a railway track gauge measuring device. Background Art
[0002] Railway track gauge inspection is a crucial component in ensuring the safety and stability of railway transportation, and its accuracy directly impacts the normal operation of trains. Improper track gauge settings can lead to train derailments and serious traffic accidents. Furthermore, excessive track gauge increases friction between the wheels and the track, exacerbating equipment wear and increasing maintenance costs. Therefore, accurate track gauge measurement is crucial to ensuring train safety. However, while traditional manual track gauge measurement methods are convenient, they suffer from low accuracy and inefficiency. In contrast, non-contact track gauge measurement using advanced technologies such as laser cameras can provide more timely and accurate track gauge information. However, this method also presents a problem: existing technologies and equipment, such as laser cameras, can exhibit deviations in detection results during the measurement process due to changes in their relative position above and below the railway track. To address these issues, it is necessary to design a railway track gauge measurement device. Utility Model Content
[0003] The purpose of the utility model is to overcome the shortcomings of the existing technology and propose a railway track gauge measuring device, which can enable the laser rangefinder to always accurately measure the required position and realize dynamic and precise measurement of the track gauge.

[0005] A railway track gauge measuring device includes mounting brackets and laser rangefinders. Two sets of mounting brackets are provided, one mounted on each side of a detection trolley frame. The mounting brackets include a vertical portion and a horizontal portion. The vertical portion is detachably mounted on the frame. Two horizontal portions are provided, one mounted on top of the other, one mounted on top of the other. Each horizontal portion is mounted with a laser rangefinder. The two laser rangefinders located at the bottom are each located at a specified distance from the top surface of the track. The laser rangefinder located on the left side of the bottom is used to measure the distance L1 between the laser light source emission point of the left laser rangefinder and the left railway track. The laser rangefinder located on the right side of the bottom is used to measure the distance L2 between the laser light source emission point of the right laser rangefinder and the right railway track. The two laser rangefinders located above are each used to measure the distance L3 between the laser light source emission points of the two laser rangefinders. The sum of L1, L2, and L3 is the gauge between the two tracks. In addition, the gauge measuring device is installed on the inspection trolley through the mounting bracket, which can move along with the inspection trolley on the railway track, avoiding the problem of deviation in the detection results due to the change in the relative position of the railway track up and down, realizing dynamic gauge detection and improving the accuracy and stability of the measurement.
[0006] Furthermore, the two laser rangefinders located at the bottom are both located 16 mm or 18 mm away from the upper surface of the track. The present invention does not impose any limitation on the above specific dimensions.
[0007] Furthermore, the vertical portion is an inverted U-shaped structure, and the top is mounted on the frame.
[0008] Furthermore, the horizontal portion includes two horizontal plates, and the laser rangefinder is installed between the two horizontal plates.
[0009] Furthermore, the mounting bracket is fixed to the frame by bolts.
[0010] Furthermore, the inspection trolley includes a crossbeam and a frame installed at both ends of the crossbeam. A driving wheel is installed at the bottom of the frame. The driving wheel is connected to a motor and is driven by the motor to enable the inspection trolley to travel on the railway track.
