Description

(54) DEVICE FOR DYNAMIC TESTS OF ELECTRIC MOBILE CURRENT TURNOVER

I

This invention relates to railway transport and relates to a device for testing current collectors.

A device for dynamic testing of current collectors of an electromotive composition is known, which contains an articulated link with the crank mechanism of a drive; i.e. an element imitating a contact wire 1.

However, this device does not simulate the movement of a current collector skid over a contact wire having zigzags in the horizontal plane, as well as a meeting of a current collector skid with protruding parts of the contact network, and therefore does not reproduce real conditions.

The purpose of the invention is to expand the functionality of the device.

This is achieved by the fact that the element imitating the contact wire is made in the form of a pipe with a longitudinal groove, inside which there is a firing pin with a protrusion inserted into the said groove and interacting with the runner of the current collector connected by means of translational movement.

FIG. 1 is a schematic diagram of the device; in fig. 2 - the same, top view; in fig. 3 and 4 - the shock mechanism of the device.

The device comprises a support 1 connected by a hinge 2. to a rod 3 located above the slider 4 of the current collector 5, the second end of which by the hinge 6 is connected to the eccentric 7 driven by the electric motor 8 through the coupling 9 and the gearbox 10. The hinge 6 can move in the eccentric 10 , giving the amplitude of the oscillations of the rod in the vertical and horizontal njioccoct х.

Inside the rod 3 is provided a striker 11 with a protrusion 12 located in the groove of the rod. Tpocolvi 13 with magnetic tape drive 14 through roller 15.

The device works as follows.

Claims (2)

During the rotation of the eccentric 7, the hinge 6 describes a circle, the diameter of which is equal to a given amplitude, and the rod 3 describes the surface of the cone with the top in the hinge 2. The bar 3 is in contact with the skid 4 and forces it to oscillate in a vertical plane. At the same time, the rod is moved along the skid in a horizontal plane. When the magnetic drive is switched on with the help of the striker 11 with the protrusion 12, the skid is hit. The device allows you to more fully simulate not only the current collector oscillations in the vertical plane, but also the movement of the current collector runner along a contact wire having a zigzag in the horizontal plane, and also allows you to create shock loads during the movement of the current collector, simulating the protrusions of the contact network as closely as possible. tests to real.
