Description

N

The invention relates to a transport technique, namely, current collecting devices, and can be used in current collection systems of high-speed electromotive rolling stock.

The purpose of the invention is to increase reliability.

The drawing shows a diagram of the proposed device.

The vehicle current collection device contains uniformly distributed over current transport means 1 current collectors 2, each of which is equipped with an automatic control unit for contact pressure with an actuator 3 associated with the automatic emergency lowering mechanism 4, and a power electrical circuit of each current collector is provided with a contactor 5 , the control circuit of which is connected to the driver's console 6. The actuating pneumatic elements of the automatic adjustment of the pressing of adjacent current collectors are interconnected via a time delay element, made in the form of adjustable throttles 7, connected to the vehicle speed sensor 8 of the vehicle 1, while the forward contactor is normally open in the direction of movement of the current collector.

The device for current collection operates as follows.

Since the actuating pneumatic elements of the self-adjusting devices of the adjacent current collectors are interconnected, a change in the height position of the front runner along the current collector causes a synchronous change in the position of the runner of the adjacent current collector, which in turn is associated with the following. The time delay element associated with the movement speed sensor provides a delay in the response of the second pneumatic element 3 in the course of movement of the automatic adjustment device. The time delay changes its value depending on the magnitude of the vehicle speed at a given point in time, ensuring that the auto-adjusting device of the second current collector triggers immediately before the participant at which the first current collector operated.

Since the auto-adjusting device is connected with the fur} {by measuring 4 automatic emergency lowering 4, the first as the current collector is triggered, it triggers (it triggers the rest without direct contact with the obstacle, which is caused by the connection of the current actuators' pneumatic elements with each other the vehicle connection can be made in the form of a pneumatic actuator, connection of one of the power pneumatic cylinders, and the elements of the time delay - in the form of adjustable depending on the speed of variable cross section chokes. With a considerable length of vehicle, it is advisable to use electric

The link providing control of the pneumatic valves is included in the power supply system of the power pneumatic cylinders.

When the vehicle is moving and when the current collectors are raised, the driver from his console 6 uses the contactor 5 to set the mode in which the forward

the current collector 2 is disconnected from the power circuit. Thus, all current collectors work under load, except the first. The first current collector in this mode works as

a pressure sensor (or altitude position) and an obstacle detection sensor on a contact network for the remaining current collectors.

For equal distances between adjacent current collectors, the time delay elements can be configured equally. When the direction of movement of the vehicle 1 changes, the former along the current pick-up becomes the latter and the current collection system works in the same way.
