Problems solved by technology

[0004] Most domestic subway urban rail vehicles are powered by overhead catenary. The traditional foot pump-assisted bow-raising device of the pantograph takes a long time to raise the bow, the pedaling force is strong, and the pressure of the bow-raising cannot be automatically judged, which brings many problems to the driver. inconvenient

Embodiment 1

[0032] An urban rail electric bow raising control device, such as Figure 1 to Figure 4 As shown, it is mainly composed of a box body (1) and a pressure controller (9) and a compressor (4) inside the box body (1). The selected pressure controller (9) is a purely mechanical structure, its contact action is strong and reliable, and it is used to judge whether the air pressure of the bow-raising pipeline is sufficient to control the start and stop of the compressor (4); the box ( 1) It consists of a bottom plate and a cover plate, above which there is a second gear knob switch (2) and an indicator light (3). The indicator light (3) indicates the working status of the electric bow raising control device, and the second gear knob switch (2) is connected To the coil of the contactor (12), the switches KT1 and KT2 of the contactor (12) are connected in parallel with the indicator light (3) and electrically connected to the control box (5). The contactor can be controlled by adjusting...

Embodiment 2

[0035] This embodiment discloses the working principle of the urban rail electric bow raising control device in Embodiment 1, as Figure 4 Shown: When the second gear knob switch (2) is in the closed state, the contactor (12) is energized, the switch of the contactor (12) is closed, and the circuit 1 of the control box (5) has DC110V voltage input; When the air pressure is lower than the lower limit of 450kPa set by the pressure controller (9), the pressure controller (9) is closed, and the circuit 3 of the control box (5) is turned on; when the circuit 3 of the control box (5) is turned on, the circuit 2 output voltage, the compressor (4) is energized to start, and starts to pump air for the bow-raising pipeline. When the bow-raising pipeline reaches the set upper limit of the pressure controller (9) 650kPa, the circuit 3 of the control box (5) is disconnected, the output voltage of the circuit 2 stops, and the compressor (4) loses power and stops working.

Abstract

The invention discloses an urban rail electric pantograph lifting control device and belongs to the technical field of rail transit. The device is mainly composed of a box body, a pressure controllerand a compressor, a switch is arranged on the box body; the switch is connected to a contactor coil; wherein the pressure controller is electrically connected with the contactor, the contactor switchis electrically connected with the control box, the power input of the control box is controlled, the control box is further electrically connected with the pressure controller and the compressor, on-off of a loop where the pressure controller is located controls starting and stopping of the compressor, and an air outlet of the compressor is connected to a pantograph lifting air circuit. The pantograph lifting control device has the advantages of being attractive and elegant in appearance, compact in structure, high in reliability, short in inflation time, low in noise, low in maintenance costand the like, the functions of automatically inflating the pantograph lifting pipeline, maintaining the air pressure of the pantograph lifting pipeline and stabilizing the pantograph catenary contactstate are achieved when the air pressure of the pantograph lifting pipeline of a train is insufficient, and pantograph lifting control convenience is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and more specifically relates to an electric bow raising control device for urban rail. Background technique [0002] When the air source pressure of the urban rail main air compressor is sufficient, the bow lift control signal controls the lift bow solenoid valve to open, and the passage is opened. At this time, the air source system of the urban rail main air compressor is filled with air, and the compressed air passes through the main air compressor. The machine air source check valve, air source filter, and bow lift solenoid valve lead to the urban rail pantograph, so that the pantograph receives electricity. [0003] When the air source pressure of the main air compressor of the urban rail is insufficient, the power of the urban rail is cut off, and the bow-raising control signal cannot be sent out. Use the manual button to control the bow-raising solenoid valve to the open position of ...
