Description

Technical Field

[0001] The utility model relates to the field of axle counter sensors, in particular to a railway axle counter sensor train speedometer. Background Art

[0002] With the continuous changes in railway transportation, the high-quality completion of railway transportation is more dependent on the stable technical status of railway infrastructure. During the railway line maintenance process, the weak links that affect the quality of line maintenance are mainly curves, switches, rail joints and other defects. Among them, curve rail wear is the most likely to occur. Incorrect rail position is the main cause of rail wear. Due to incorrect rail position, the inner and outer rails are unevenly loaded, resulting in rail bias. Unsteady train travel generates additional force hitting the rails, accelerating rail wear. Excessive or insufficient superelevation causes rail unbalanced loading and abnormal wheel-rail contact. If the superelevation is too large, the train weight is unbalanced on the inner rail, increasing vertical wear of the inner rail and causing crushing. It also has a negative impact on the lateral wear of the outer rail. If the superelevation is too small, it also has a negative impact on lateral wear of the rail. Therefore, if the superelevation height is not appropriate, it will cause unbalanced loading of the inner and outer rails and abnormal wheel-rail contact, thereby exacerbating rail wear. Therefore, it is necessary to use axle counter sensors to measure the vehicle speed and adjust the rail position accordingly to reduce wear.

[0003] However, the current installation of axle counter sensors requires the use of ballast passing under the track for clamping installation, which is more troublesome to install, and clamping installation is difficult to achieve when dealing with ballastless track. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-4 As shown, this embodiment provides a railway axle counter sensor train speedometer, including a data control box 1 and an axle counter sensor 2. The axle counter sensor 2 is provided with a fixing mechanism 5, which includes: a rotating sleeve 501, an engaging ear plate 502, the engaging ear plate 502 is fixedly connected to the axle counter sensor 2, a first screw rod 503 is installed on the inner side of one end of the rotating sleeve 501, and a second screw rod 504 is installed on the inner side of the other end of the rotating sleeve 501. The first screw rod 503 and the second screw rod 504 are both engaged and rotatably connected with the rotating sleeve 501, and the inner side of the engaging ear plate 502 is provided with a screw rod 503. The tooth patterns that mesh with the first screw rod 503 and the second screw rod 504 are in opposite directions on the outer sides of the first screw rod 503 and the second screw rod 504. By controlling the torque applied to the rotating sleeve 501, the lifting and lowering of the first screw rod 503 and the second screw rod 504 can be synchronously controlled. A waist-shaped hole 3 is provided inside the axle counter sensor 2. The waist-shaped hole 3 is connected to the axle counter sensor 2. A positioning ring 301 is installed inside the waist-shaped hole 3. A suction cup 4 is provided inside the positioning ring 301 below the axle counter sensor 2, and a tilting rod 401 is installed on the upper end of the suction cup 4.

[0023] like Figure 2-3 As shown, in this embodiment, a data wire 6 is connected between the data control box 1 and the axle counter sensor 2, and the data control box 1 and the axle counter sensor 2 are electrically connected through the data wire 6. The data control box 1 is externally connected to the control host, and the inner wall of the positioning ring 301 is provided with an adjustment tooth 302, and the outer side of the suction cup 4 is provided with an engagement tooth 402 corresponding to the position of the adjustment tooth 302. The suction cup 4 is rotatably connected by meshing with the adjustment tooth 302 through the engagement tooth 402, thereby controlling the distance between the suction cup 4 as a whole and the axle counter sensor 2, so as to facilitate adsorption to the rail.

[0024] The working principle of the present invention is as follows: during installation, according to the degree of curvature of the entire rail, a torsional force is applied to the suction cup 4 as a whole to control the rotation of the meshing tooth pattern 402 inside the adjustment tooth pattern 302, and the distance from the suction cup 4 to the lower surface of the axle counter sensor 2 is adjusted. After the axle counter sensor 2 as a whole is fitted with the side of the rail with the suction cup 4, a force is applied to the tilting rod 401, and the air between the suction cup 4 and the rail is discharged. The axle counter sensor 2 is adsorbed on the rail body by the suction cup 4 as a whole. When the rail body at the position to be detected is not smooth enough (such as the joint position of two rails), or the curvature of the rail at the detection position is too large and the suction cup 4 cannot ensure stability, the suction cup 4 is used. After applying torque to the rotating sleeve 501 as a whole, the rotating sleeve 501 as a whole will engage and rotate synchronously with the first screw rod 503 and the second screw rod 504, and the first screw rod 503 and the second screw rod 504 are controlled to rotate with the engaging ear plate 502 to extend toward the outside of the axle counter sensor 2, so that the first screw rod 503 contacts the lower jaw of the rail head and the second screw rod 504 contacts the bottom of the rail. This can achieve the goal of supporting the axle counter sensor 2 as a whole on the inner side of the track, thereby ensuring the overall installation stability of the axle counter sensor 2. When the train passes by the axle counter sensor 2, the signal is collected and transmitted to the data control box 1 through the data wire 6. The data control box 1 and the host receive the data through wireless communication.
