Rail transit sanding device based on wind feeling

Abstract

The invention relates to the technical field of intelligent transportation. The invention discloses a rail transit sanding device based on wind feeling. The device comprises a device body; a top coveris arranged at the top of the device body; a sand outlet is formed in the bottom of the device body; a trigger switch is movably connected with the end, away from an extrusion spring, of a connectingrod; a trigger spring is movably connected with the end, away from the connecting rod, of the trigger switch; and a driving screw is arranged in the device body. The invention discloses the rail transit sanding device based on wind feeling. Due to the rotation of the driving screw, a driving rod connected with the driving screw is driven to start to reciprocate on the driving screw to drive gravel in the device to move, and a stirrer is mounted on a mounting plate to stir the gravel in the device, so that the sanding speed is increased, and the phenomena that moisture in the device is increased, condensed water is formed in the sudden temperature drop process, and solidification and hardening occur due to the fact that the moisture reversely enters the device through the sand outlet are avoided.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a wind-sense-based sand spreading device for rail transit. Background technique [0002] Due to the influence of rain, snow, frost, etc. during the operation of rail vehicles, wheel skid problems will occur. However, wheel sliding will bring great harm to the operation of the vehicle: the light one will scratch the wheel, and the severe one will prolong the braking distance, which will cause safety accidents; Coefficient device to reduce the risk of sliding of rail vehicles. [0003] At present, the sand boxes of domestic sand spreading devices are all connected to the atmosphere. Moisture enters the sand box through the sand spout in the opposite direction, causing the moisture in the sand box to increase. When the temperature drops suddenly, condensed water is formed, and solidification and hardening occur. Therefore, an important research direction of the ...

AI Technical Summary

Problems solved by technology

Due to the effect of negative pressure, the above-mentioned sand spreader can speed up the sand transmission speed to a certain extent, but it cannot effectively isolate the communication between the sand and the atmosphere, nor can it ensure that the sand remains in a loose state.

[0005] Therefore, we proposed a sanding device for rail transit based on wind sensing. The built-in wind sensor senses the external wind force, so that the device is sanding, and stirring speeds up the speed of sanding and avoids moisture. Reversely entering the sand box through the sand spout causes the moisture in the sand box to increase, and condensed water is formed when the temperature drops sharply, and the phenomenon of solidification and hardening occurs
