Technical Field

The invention relates to the field of railway contact networks, in particular to a supporting mechanism of an electrified railway contact network.

Background

A high-speed railway contact net is a power transmission line which is erected over a railway line and supplies power to an electric locomotive, and current relied on by the running of a high-speed railway train is transmitted through the contact net at the upper end of the locomotive. Once the contact net has a power failure, or the contact between the train pantograph and the contact net is poor, the power supply of the train is affected. The high-speed railway contact net is a special form of transmission line which is erected over a railway line and supplies power to an electric locomotive. It is composed of contact suspension, supporting device, positioning device, supporting column and foundation. The contact suspension comprises a contact wire, a dropper, a carrier cable and a connecting part. The contact suspension is mounted on a support column by means of a support device and serves to supply the electric locomotive with electric energy obtained from the traction substation. The support device is used to support the contact suspension and to transmit its load to the support post or other building. The supporting device comprises a cantilever, a horizontal pull rod, a suspension insulator string, a rod insulator and other special supporting equipment of the building. The positioning device comprises a positioning pipe and a positioner, and is used for fixing the position of the contact line, ensuring that the contact line is within the running track range of the pantograph slide plate, ensuring that the contact line is not separated from the pantograph and transmitting the horizontal load of the contact line to the support. The support posts and the foundation are used to bear the entire load of the contact suspension, support and positioning device and to fix the contact suspension at a given position and height. The contact net in China adopts prestressed reinforced concrete pillars and steel columns, and the foundation is for the steel pillars, namely the steel pillars are fixed on the foundation made of the reinforced concrete below, and the foundation bears the whole load transmitted by the pillars and ensures the stability of the pillars. The prestressed reinforced concrete pillar and the foundation are made into a whole, and the lower end of the prestressed reinforced concrete pillar is directly buried underground.

The existing support mechanism of the railway contact net adopts a hanging hammer to straighten a contact line in design, and adopts a dropper to pull the contact line to correct the contact line, so that the contact line is prevented from being deformed greatly; in order to correct the curvature of the contact line, it is necessary to consider the correction to be performed, a lot of time is required, and the operation is troublesome.
