DETAILED DESCRIPTION

[0015] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0016] In order to further understand the content of the utility model, the utility model will be described in detail in combination with the drawings.

[0017] In combination with Figures 1 to 4As shown, the utility model discloses a rail profile and wear measuring instrument, including main beam 1, push mechanism 2 and control terminal 3, the middle position of main beam 1 rear end is provided with push mechanism 2, the top of push mechanism 2 is provided with control terminal 3, the right side of main beam 1 is provided with right walking mechanism 4, the left side of main beam 1 is provided with left support 5, the inner side wall of left support 5 is provided with mileage measuring mechanism 51, the top of left support 5 is provided with measuring box 6.

[0018] Preferably, the two ends of the bottom of the left support 5 are provided with left walking mechanisms 52, and the bottom of the left support 5 is provided with a through slot 53.

[0019] Preferably, the top end of the inside of the measuring box 6 is provided with three laser detection mechanisms 61, the laser detection mechanisms 61 on both sides of the top end of the inside of the measuring box 6 are inclined towards the bottom end of the left support 5, and the laser detection mechanism 61 at the middle position of the top end of the inside of the measuring box 6 is perpendicular to the position of the through slot 53.

[0020] Working principle:

[0021] Through the cooperative operation of the right walking mechanism 4 and the left walking mechanism 52, the rail profile and wear measuring instrument is placed on the track under the assistance of the push mechanism 2. The three laser detection mechanisms 61 in the measuring box 6 immediately detect the top and both sides of the track. After the laser beam forms a light spot on the surface of the rail, any slight change in the profile of the rail will cause the reflected laser path to change. The instrument receives the reflected light and calculates to obtain the position information of each point on the surface of the rail, and completes the profile data collection.

[0022] At the same time, the mileage measuring mechanism 51 synchronously detects the mileage information and records the mileage number of corrugation occurrence, greatly facilitates the maintenance personnel to quickly locate the track position to be repaired, avoids blind search, and greatly improves the maintenance efficiency.

[0023] For the top of the track detection, the vertical wear condition of the rail under the long-term rolling of the train can be directly reflected, the wear value of the top of the rail head can directly reflect the change of the ability to bear the weight of the train, and the problems of metal fatigue and deformation caused by vertical pressure can be found in time, so as to prevent the rail head top from appearing diseases such as peeling and chipping, and to ensure the basic stability of train running. The side detection is also crucial. When driving on a curve, the centrifugal force of the train makes the wheel and the side of the rail produce strong friction. The side detection can accurately grasp the side wear degree. Once the wear exceeds the standard, the train guiding performance is affected, the risk of derailment is increased, and the like. In addition, the side detection can also find the scratches and scratches that may exist on the side of the rail head. These defects may become stress concentration points in subsequent operation and cause more serious safety hazards. Through the comprehensive detection of the top and both sides, a complete rail surface condition evaluation system can be constructed to provide comprehensive and detailed data support for track maintenance, so that the track is always in a safe and reliable running state, and the efficient and safe railway transportation is effectively guaranteed.
