The main purpose is to prevent oxidation corrosion, especially electrochemical corrosion, between the contact wires and the busbar.
In the current contact line coating device, the paste coating head is generally handheld, and the construction is often clamped due to the influence of resistance factors such as local bending of the contact line, and the contact line can be damaged. Therefore, construction units generally give up use. During practical construction, the gloves are used for direct coating, and the defects that coating is uneven, the contact line grooves are filled up and contact line circumferences are piled up, the coating overflows after the bus bars are pinched into the contact line grooves, so that the waste is large and attractive, dust can be adsorbed by the piled up and overflowed coating, and the service lives of the contact line and the power receiving slide plate can be influenced by discharge electric arcs; intermittent uncoated phenomena also occur.

When the device is used for coating grease media, the pressure of the grease cavity needs to be manually controlled so as to supplement the consumption of grease, pressure fluctuation cannot be avoided due to manual operation, the pressure uniformity of the grease cavity cannot be ensured during coating, so that continuous uniformity of grease coated on a contact line cannot be realized, the pressure grease cavity cannot be automatically controlled, and manual labor is increased.
The present invention has been made in view of this.

To ensure uniform coating, the pressure within the relief cavity 106 must be near "normal pressure", the lower the pressure within the coating cavity 105, the better. The control system opens and closes the paint 400 control valve through the cooperation of the magnetic switch, the relay and the electromagnetic directional valve, so that the pressure of the paint 400 input into the paint cavity 105 is less than or equal to 0.05MPa, and the pressure of the paint 400 in the pressure relief cavity 106 is close to normal pressure. The specific implementation principle is as follows:
before the device works, the relative pressure in the pressure gas cavity of the pressure control oil cylinder is 0. After the device starts to work, the dry oil pump 600 inputs the paint 400 into the control cylinder cavity 214 of the paint control valve through the high-pressure oil pipe 219, and the paint 400 in the control cylinder cavity 214 sequentially passes through the paint outlet 217, the feed inlet 108, the paint cavity 105, the outer through hole 109, the paint inlet 234 and finally enters the pressure cylinder cavity 232 of the pressure control cylinder. The pressure of the coating 400 in the coating cavity 105 during this process is slightly greater than 0.
The paint 400 entering the pressure cylinder cavity 232 pushes the magnetic piston 231 to move towards the second magnetic switch 242, when the magnetic piston 231 reaches the second magnetic switch 242, the second magnetic switch 242 is closed, the second relay 252 is closed after the second magnetic switch 242 is closed, the relay 1 is simultaneously opened, the second electromagnetic coil 2242 is closed and electrified after the second relay 252 is closed, an electromagnetic field generated after the second electromagnetic coil 2242 is electrified attracts the electromagnetic piston 221 of the electromagnetic reversing valve, and when the electromagnetic piston 221 moves to the second electromagnetic coil 2242, the second air outlet 226, the first air outlet 227 and the first air inlet 2151 of the paint control valve are communicated through the guide pipe; the air inlet 228, the first air outlet 225, and the second air inlet 2161 of the paint 400 control valve are communicated by the first outer baffle ring 222.
After the second air inlet 2161, the first air outlet 227 and the first air inlet 2151 of the paint 400 control valve are communicated, the relative pressure of the first cylinder chamber 215 of the paint 400 control valve is 0; after the air inlet 228, the first air outlet 225 and the second air inlet 2161 of the paint control valve are communicated, the pressurized air entering the first cylinder chamber 215 of the paint 400 control valve pushes the piston 211, causing the paint control valve to close. While the paint control valve is closed, the pressure gas at the first gas outlet 225 is depressurized to 0.05MPa by the micro pressure regulating valve and enters the pressure cylinder chamber 233 through the gas inlet 235 of the pressure control cylinder.
Because the paint 400 in the paint cavity 105 of the paste applicator is consumed by continuing to coat, the pressure of the paint 400 is gradually reduced, and the paint 400 in the pressure cylinder cavity 232 of the pressure regulating cylinder connected with the outer through hole 109 of the paste applicator is back-pressed into the paint cavity 105 of the paste applicator by the pressure gas of 0.05MPa in the gas cavity through the magnetic piston 231, and at the moment, the pressure of the paint 400 in the paint cavity 105 of the paste applicator is less than or equal to 0.05MPa.
When the magnetic piston 231 reaches the first magnetic switch 241, the first magnetic switch 241 is closed, the first relay 251 is closed after the first magnetic switch 241 is closed, the relay 2 is simultaneously opened, the first electromagnetic coil 2241 is closed and electrified by the closing of the first relay 251, the electromagnetic field generated after the first electromagnetic coil 2241 is electrified attracts the electromagnetic piston 221 of the electromagnetic reversing valve, and when the electromagnetic piston 221 moves to the first electromagnetic coil 2241, the first air outlet 225, the second air outlet 229 and the second air inlet 2161 of the coating control valve are communicated through the flow guide pipe; the air inlet 228, the second air outlet 226 and the first air inlet 2151 of the paint 400 control valve are in communication via the second outer baffle 223.
After the first air outlet 225, the second air outlet 229 and the second air inlet 2161 of the paint control valve are communicated, the relative pressure of the second cylinder chamber 216 of the paint control valve is 0, and the relative pressure of the pressure cylinder chamber 233 of the pressure control cylinder communicated with the first air outlet 225 is also 0; after the air inlet 228, the second air outlet 226 and the first air inlet 2151 of the paint control valve are in communication, the pressurized air entering the first cylinder chamber 215 of the paint control valve back-presses the piston 211, causing the paint control valve to open and continue to deliver paint 400 to the applicator chamber 105.
The paint 400 in the paint cavity 105 of the paste applicator enters the pressure cylinder cavity 232 of the pressure regulating cylinder again, and the above process is automatically circulated repeatedly, and the paint 400 of about 0.05MPa is input into the paint cavity 105 of the paste applicator, so that the paste applicator can automatically and continuously apply paint.
By setting the flow rate of the paint control valve slightly larger than the coating consumption of the paste applicator, the pressure in the paint chamber 105 can be stably controlled to be about 0.05MPa, and the paint 400 in the pressure relief chamber 106 is reduced in pressure by the first coating ring 103 and then is again coated and consumed by the second coating ring 103, wherein the pressure is less than 0.05MPa, and the pressure is close to normal pressure.
The components such as the coating 400 control valve, the pressure control oil cylinder, the oil cylinder external magnetic switch, the miniature pressure regulating air valve and the like are covered by a stainless steel cover, and the stainless steel cover is fixed on the bottom surface of the outer wall of the lower flap of the paste applicator, so that the whole structure is attractive and elegant.
In this embodiment, the control system controls the pressure in the coating cavity 105, so as to ensure that the coating 400 in the coating cavity 105 is in a preset stable state, and facilitate the contact line 500 to coat the coating 400. The control system realizes automatic control of the pressure of the paint cavity 105 through the cooperative operation of the paint 400 control valve, the pressure control oil cylinder and the electromagnetic reversing air valve, so that the paint cavity 105 can be coated efficiently and conveniently, the labor force can be reduced, and the resources can be saved.
