Mobile contact line supporting device and mobile contact network system

Abstract

The invention relates to a mobile contact network supporting device and a mobile contact network system, and the mobile contact network supporting device is arranged on a stand column in the contact network system and comprises a cantilever, a power device, a balance weight and a balance weight driving device. The cantilever comprises a contact line connecting section, a balance weight connectingsection and a hinge structure between the contact line connecting section and the balance weight connecting section and is hinged to the stand column through the hinge structure, the contact line connecting section extends out of one side of the stand column, and the balance weight connecting section is located on the other side of the stand column; the power device is arranged on the stand columnand can drive the cantilever to rotate relative to the stand column; the balance weight is movably arranged on the balance weight connecting section of the cantilever, and the distance between the gravity center of the balance weight and the stand column changes when the balance weight moves relative to the cantilever; the balance weight driving device is used for driving the balance weight to move relative to the cantilever. The balance weight driving device can enable the angle between the balance weight and the cantilever to be adjustable, larger balance torque can be provided, and power needed when the cantilever rotates is reduced.

Description

technical field [0001] The present disclosure relates to the field of moving catenary technology, and in particular to a moving catenary support device and a moving catenary system. Background technique [0002] The mobile catenary can be applied to the freight yard in the electrified railway transportation system, which can eliminate the operation of the diesel locomotive pulling the electric locomotive into and out of the yard. In the mobile catenary, it is necessary to set up multiple columns along the track of the freight station, and the supporting device for supporting the catenary cable and the contact line needs to be installed on the column. The supporting device should be able to move actively or passively so that the connected catenary cable and contact line The contact line is moved from above the track to one side. A Chinese patent application "CN101306652A-Horizontal Rotating Rigid Movable Catenary System" discloses a movable catenary system, the supporting de...

Problems solved by technology

With this cantilever structure, the bending moment generated by the gravity of the cantilever and the contact line on the hinge shaft is all borne by the hinge bearing, which has a great influence on the life of the cantilever hinge shaft

In some improvements, the movement of the cantilever can be changed to turn up and down. When the angle between the cantilever and the column becomes smaller, the force of gravity on the hinge axis will decrease, so the moment will also decrease; but the angle between the cantilever and the column is smaller. When the value is large, the situation where the torque at the hinge shaft is large still cannot be improved
