Abstract

The invention discloses a portable track scale and device, and the device comprises a load-bearing limiting strip and a plurality of locking devices which are uniformly and fixedly connected to a track steel rail, and each locking device comprises a U-shaped fixing seat, an L-shaped sensor fixing seat, an L-shaped positioning seat, and a micro-strain shaft type sensor. The U-shaped fixing seat isconnected with and wraps the bottom face of the rail steel rail, the L-shaped sensor fixing seat and the L-shaped positioning seat in a sleeved mode, and the side portion of the L-shaped sensor fixingseat and the side portion of the L-shaped positioning seat are matched with the inner side and the outer side of the rail steel rail respectively and extruded on the inner side and the outer side ofthe rail steel rail at the same time.The L-shaped sensor fixing seat is provided with a micro-strain shaft type sensor; Two ends of the micro-strain shaft type sensor are respectively fixed on the L-shaped sensor fixing seat and the U-shaped fixing seat, and the micro-strain shaft type sensor is connected in series with the load-bearing limiting strip. The load-bearing limiting strip is connectedwith the plurality of lockers, the structure is compact, the installation is simple and firm, the split combination is achieved, the carrying is convenient, the device can be used for different rail weighing places, the weighing precision is ensured in a dynamic state, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of rail transport weighing, in particular to a portable rail scale and its device. Background technique [0002] Rail scales are weighing instruments for weighing railway freight vehicles. There are three types: static track scale, dynamic track scale and light track scale. Widely used in factories, mines, metallurgy, foreign trade and railway departments to weigh bulk goods on trucks. [0003] At present, most rail scales are detected and weighed by installing sensors on or under the rails. However, this type of track claims often needs to change the overall structure of the track during installation. It is extremely inconvenient to install, remove and carry. [0004] There are also track scales for easy portability and installation, but most of these portable track scales have the problems that the overall structure is easy to loose, the weighing accuracy cannot be guaranteed and the service life is ...
