Description

The invention relates to electrical equipment, vehicles with electrodes, and specifically to means of controlling the current collectors of diesel trolleys.

The purpose of the invention is to automatically control the current pickup position depending on the location of the contact actuator.

The drawing shows a pantograph with a hydraulic actuator and a device for controlling, an abundance of view.

The current collector contains a moving; base 1, moving frames 2, a skid: 3, contact inserts 4 interacting with contact wire 5, deliverers 6 of the presence of contact I wire. The movable base 1 is connected to the rods of the hydraulic cylinder 7. I Sensors 6, mounted on the skid I3, are connected to the input of the block 8 craw-; on which a constant signal is supplied from the support element 9, the Comparison Units 8 are connected to the executive bodies 10 of the hydraulic distributors via the elements 12 of the control-: laziness, which are interconnected by the generator 13. The hydraulic distributors

1I connected to hydrodil or schru 7. The device works as follows.

When maneuvering a diesel trolley, contact wire 5 moves along sensors 6 mounted on skid 3, causing EMF in them. When the contact wire 5 is located on one of the cables of the runner 3 above the extreme sensors, the input to the comparison unit 8 is a signal that compares with the signal of the supporting element 9. If the signal from the sensor 6 is greater than the signal of the supporting element, then this signal is amplified by the element

12 controls, and the executive body 10 opens the channels of the hydraulic distributor 11 and passes the working fluid through one of the rod cavities of the hydraulic cylinder 7, and on the other

rod cavity working fluid through the valve 11 passes

on plums. As a result, the piston with the rods together with the movable base 1 is moved to the required distance. For synchronous operation, a generator 13 is used in the control unit, which simultaneously includes two hydraulic distributors: one to create pressure in the rod cavity, and the second to drain fluid from the other rod cavity.

Thanks to the proposed device, a diesel trolley, moving along the contact network, can be moved to the left or right side for an additional distance, which significantly increases its maneuverability.
