Description

TECHNICAL FIELD

[0001] The utility model relates to the field of steel rail straightness inspection technology, and specifically relates to a steel rail straightness inspection device for railway track. BACKGROUND

[0002] Railway track straightness refers to the straightness of the track in the horizontal and vertical directions, and it is one of the important parameters for measuring the quality of the railway track. Good straightness can ensure the stability and safety of train operation, reduce the friction and wear between the wheel and the rail, and prolong the service life of the track and the vehicle. The detection of the straightness of the railway track usually uses high-precision measuring equipment, such as non-contact laser sensors. These devices can quickly measure the geometric deviation of the track, including the longitudinal center line of the rail top surface and the straightness deviation, without contacting the track. These measurement results are crucial for the maintenance and repair of the track, as they can help engineers identify the track sections that need to be adjusted or replaced to maintain the efficiency and safety of railway transportation.

[0003] The existing Chinese utility model patent with the authorization announcement number CN216977867U specifically discloses a railway track steel rail straightness inspection instrument, which relates to the field of steel rail straightness inspection technology. The utility model includes a fixed plate and a clamping block. A lead screw is arranged between the front and rear fixed plates. A plurality of clamping blocks are arranged on the left and right sides of the lower surface of the fixed plate. A sliding rod is arranged between the front and rear adjacent clamping blocks. An installation bracket is slidably arranged on the sliding rod. A first sensor is installed on the vertical surface of the inner side of the installation bracket. A second sensor is installed on the horizontal surface of the inner side of the installation bracket. A sliding block is arranged on the lead screw. A fixed support is connected between the sliding block and the installation bracket. The device can be easily clamped on two adjacent steel rails through the clamping block. The lead screw can be easily adjusted to move the sliding block forward and backward. Under the action of the fixed support and the sliding rod, the first sensor and the second sensor are driven to slide along the steel rail forward and backward in combination with the installation bracket to measure the steel rail, achieving the purpose of simultaneously measuring two steel rails and greatly improving the measurement efficiency.

[0004] However, in the current detection of the straightness of the railway track, it is necessary to continuously measure the railway track when measuring railway tracks of different sizes, which requires the straightness detector to be picked up and put down multiple times, consuming a lot of time. Generally, the straightness inspection instrument for railway track is used to slide the straightness detection head along the outer wall of the steel rail to check the straightness of the steel rail surface, which easily causes the straightness detection head to wear out and has a short service life.
