High-strength elastic suspension assembly

Technical Field

The utility model relates to an equipment technical field for the contact net especially relates to a high strength elasticity hangs subassembly.

Background

The development of social traffic is powerfully promoted by the electrified railway and urban rail traffic, and the convenient and efficient development of the urban rail traffic creates value for modern life of people. The traditional bus bar hanging and positioning device belongs to a rigid structural part, and the axial direction and the radial direction of the device have high rigidity without elastic characteristics.

When the electric locomotive is in operation, the contact surface of the pantograph and the contact line is in a sliding friction state, and in order to ensure normal current collection, contact pressure in a certain range exists between the pantograph and the contact line. If the suspension positioning points are in a rigid suspension state, the changes of the contact pressure, the relative position and the speed among the bow nets cannot be compensated to generate sudden changes, so that the bow net relation generates transient changes, and if the transient changes reach a quantitative standard, the most direct result is that the normal contact and current collection among the bow nets are destroyed, and the abrasion or impact damage of contact wires and a carbon pantograph slider is accelerated; secondly, arcing and sparks can occur at the suspension anchor points, directly damaging the pantograph and the contact wires.
