RAIL-MOUNTED LOAD-CELL SCALES

Abstract

The invention relates to apparatuses for the wheel-by-wheel weighing of railway wagons during motion. Essence: the scales comprise deformation sensors (2), temperature sensors (3) secured to working rails (1) by an adhesive process, polymer plates (6), metal plates (7) and controllers which are arranged externally to a rail track. Circuit boards (5) of the controllers are arranged on the working rails (1) in recesses formed by the polymer plates (6) and metal plates (7). Furthermore, the deformation sensors (2), temperature sensors (3) and circuit boards (5) of the controllers are hermetically encapsulated by means of said set of plates (6, 7). Technical result: simplification of the design and installation of scales and reduction in the probability of electrical interference in measuring networks.

Claims

1. Rail-mounted load-cell scales, comprising: strain sensors, temperature sensors secured to working rails by an adhesive process and encapsulated by means of a set of metal and polymer plates, and controllers arranged externally to a rail track, wherein circuit boards of the controllers are arranged on the working rails in recesses of said set of plates.

2. The rail-mounted load-cell scales according to claim 1, wherein the strain sensors, temperature sensors are on the opposite side of the working rails.

3. The rail-mounted load-cell scales according to claim 1, wherein the controllers are coupled to a computer and a power supply.
