Description

Technical Field

[0001] The utility model relates to a railway axle counting device, belonging to the field of railway axle counting. Background Art

[0002] Railway axle counter equipment is equipment used for railway track maintenance, inspection and measurement. Railway axle counters are used to measure the distance between each axle end on the track, detect whether the track gauge meets the standard, and assist in positioning and correcting the track. Most of the existing railway axle counters are directly installed on the rails by bolts. For example, a protective device suitable for track axle counters disclosed in publication number CN209479685U is to directly install the railway axle counter on the track through a protective shell. The existing railway axle counters can also be directly clamped on the rails through a clamp seat, such as an axle counter device for a subway signal system disclosed in publication number CN217515168U. However, the above two methods have the following defects when the equipment is disassembled, replaced and inspected: 1. During disassembly, it is impossible to remove only the railway axle counter alone, and it needs to be repositioned during installation; 2. The height position is fixed after installation, and adaptive height adjustment cannot be performed; 3. Disassembly and installation require the unscrewing of multiple bolts, which is more cumbersome.
