A multifunctional antifreeze spraying device and its application method

Abstract

The invention belongs to the technical field of mechanical design and control and relates to a multifunctional antifreezing solution spraying device and usage thereof. The multifunctional antifreezing solution spraying device is characterized in that all-directional uniform spraying on the inner surfaces of carriages can be realized by the device, spraying can be paused at connection neutral positions between carriages, and the device is capable of ascending and descending vertically and rotating horizontally for the convenient of equipment maintenance and repair and pass of high-position track operation equipment. A nozzle can be adjusted to proper positions through vertical ascending and descending according to different carriage heights to realize low-position spraying and prevent antifreezing solution from being blown outside the carriages. When spraying is paused because of the carriage connection neutral positions or carriage absence, an anti-leakage tray is turned below the nozzle to receive leaked solution and then turned beside the nozzle to pour the leaked solution into the carriages when spraying is performed again, thereby the antifreezing solution is prevented from leaking on carriage connection hooks to result in hook corrosion or leaking on the ground to cause environment pollution, and waste of the antifreezing solution is avoided as well.

Description

technical field [0001] The invention relates to a multifunctional antifreeze spraying device and a method for using the same, which belong to the technical field of mechanical design and control. It specifically relates to a device that is easy to maintain and repair, can meet the needs of high-efficiency and uniform antifreeze spraying at different car heights, and when not spraying, the residual liquid in the nozzle and its connecting pipes will not leak to the outside of the train car and the car hook. A technical proposal of an antifreeze spraying device and a method for using the same. Background technique [0002] Railway is the main channel for coal transportation in my country. According to statistics, the transportation volume of water-containing coal by railway is close to more than 70% of the total transportation volume. Coal is easy to freeze when the railway department transports coal in winter. If it is not handled in time, it will bring great difficulties to ...

AI Technical Summary

Problems solved by technology

[0006] 1. The nozzle can not automatically change the angle, and can not guarantee the uniform spraying of the inner wall of the front and rear end surfaces of the carriage

[0007] 2. Most of the spraying devices do not have the lifting function, which leads to the high height of the spraying device from the track surface. When spraying the low compartment, part of the antifreeze is directly sprayed outside the compartment, or is blown out of the compartment by the wind, resulting in waste of antifreeze and damage to the environment. Pollution

[0008] 3. Most of the spraying devices do not have the functions of vertical lifting and horizontal rotation at the same time, resulting in maintenance personnel having to carry out high-altitude operations when maintaining and repairing the devices, which increases maintenance costs and poses safety hazards

[0009] 4. During the spraying process of most spraying devices, when encountering positions that do not need to be sprayed, such as the front of the car, the car compartment, etc., even if the spraying solenoid valve can be closed, the antifreeze in the nozzle and its connecting pipe will still drip. Corrosion of important parts such as the connecting hook of the carriage, and the waste of antifreeze
