SU1229087A1 - Device for suspending contact wires - Google Patents

Description

The invention relates to urban electric transport, in particular, to devices of uncompensated and compensated simple suspensions of a tram and trolleybus contact network, primarily intended for use under engineering structures: under bridges, overpasses, in tunnels.

The purpose of the invention is to ensure the elasticity of the contact suspension by installing compression springs.

Fig. 1 shows a device for suspending contact wires, a general view; Fig. 2 shows the directions of the rod with clips for the contact wire; in fig. 3 - adjustable compression spring with washers.

The device for suspending the con-and-stroke wires is made in the form of a flexible cross member and contains clamps 1 for the contact wire, insulators 2, which provide two-step insulation of the contact wire 3 to grounded parts, pillars 4, through holes in which rods 5 pass are equipped with adjustable compression springs 6 with washers 7 and 8. Washers 8 facing the surface of the uprights 4 have a spherical side surface to provide free

 move the rods 5 in a vertical plane.

The contact wire 3 is attached to the flexible crossbar with clips 1

5 and the guide rod 9. The fastening of the springs 6 is carried out by nuts 10,

The device works in the following way.

10 The mass of the device and the contact wires 3 on a length equal to one span is perceived by springs 6, which are partially deformed, provide the elasticity of a simple contact

15, similar in size to the mid-span elasticity.

With the passage of the current collector under the action of pressing force is moving the contact wires 3 up,

20, the spring 6 is unloaded and the elasticity of the flexible cross member changes. The varying amount of elasticity contributes to the rapid damping of the suspension oscillations, which occur when interacting with the current collector.

In the case of temperature changes, the longitudinal movements of the contact wires 3 are provided by free re-mesh, guide rods 9 with respect to the flexible cross member.
