Rotating arm type antifreezing fluid spraying device for two-lane coal trains

Abstract

The invention relates to a rotating arm type antifreezing fluid spraying device for two-lane coal trains, belongs to the technical field of mechanical design and control, and in particular relates to an antifreezing fluid spraying device capable of evenly spraying antifreezing fluid from a position close to a nozzle to five surfaces in carriages of the coal trains in short distance. The antifreezing fluid spraying device is characterized by consisting of a square upright post 1, a side attached fastening device, a drive reducing mechanism, a swing mechanism, an upper connecting plate 12, a lower connecting plate 13, a multi-azimuth nozzle steering mechanism and a control system; and the antifreezing fluid spraying device makes operators far away from the spraying field by utilizing remotecontrol, reduces the labor intensity of the operators, improves the labor environment, saves the dosage of the antifreezing fluid, saves the cost, ensures the safety of human bodies and transportation, can automatically recognize the carriages and headstocks, begins spraying when the carriages enter a spraying area, stops spraying when the carriages leave the spraying area, does not spray the fluid when couple empty spaces between the carriages and the headstocks of locomotives pass, and really realizes the full automatic antifreezing fluid spraying of railroad coal trains.

Description

1. Technical field [0001] The invention is a swing-arm type antifreeze spraying device for a two-lane coal-transporting train, which belongs to the technical field of mechanical design and control, and specifically relates to a device capable of uniformly spraying antifreeze from a nozzle to five compartments of a coal-transporting train at short distances. Surface antifreeze spray device. 2. Background technology [0002] The weather in northern my country is cold in winter, and goods such as coal and ore powder transported by railways are easy to freeze in the car. The problem of coal transport frozen cars has brought huge economic losses to mines, roads, ports and other departments. The main forms of loss are: the loss of residual coal from frozen vehicles, the waste of transport capacity caused by the round-trip transportation of residual coal from frozen vehicles, the funds used to clean up residual coal from frozen vehicles, the prolonged residence time caused by froze...

AI Technical Summary

Problems solved by technology

Since a train has a lot of wagons, and many trains need to be loaded in a day, the workload is very heavy, and it is easy to cause waste of antifreeze

[0007] There are also some coal preparation plants that have designed an automatic spraying system, adding an automatic control part, using several photoelectric sensors to measure the position of the wagon, and controlling the spraying liquid to achieve the purpose of saving labor. Although the effect is better than manual spraying, But there are still deficiencies: on the one hand, the nozzle can not automatically change the angle, and can not guarantee the uniform spraying of the inner wall of the wagon.

On the other hand, since the automatic spraying system needs to meet the requirements of the basic railway building limits stipulated in the national standard GB146.2-83 to ensure the safety of rolling stock passing, the height of the spraying device from the track surface is too high, It still causes uneven spraying effect on the inner wall of the car wagon, and a serious waste of antifreeze
