Abstract

The invention discloses a centrifugal fly claw ratchet wheel braking locker in the technical field of contact nets, comprising an inner tooth ratchet wheel, a fly claw and a fly wheel, wherein the inner tooth ratchet wheel is sleeved on the fly wheel, the outer circumference of the fly wheel is at least provided with a fly claw slot, and the fly claw is plugged in the fly claw slot; an elastic mechanism for driving the fly claw to be contracted in the fly claw slot is arranged between the fly claw and the fly wheel; and the end part of the fly claw corresponds to ratchet teeth of the inner tooth ratchet wheel. After the line of a contact net is suddenly broken, the fly wheel is quickly forced to brake. The invention also discloses a contact net compensation device with the centrifugal fly claw ratchet braking locker, comprising a rotatable spindle arranged on a bracket, wherein a large-diameter tensioning thread wheel and a small-diameter thread wheel which are mutually linked are arranged on the spindle; a steel wire rope for suspending a sliding weight is wound outside the large-diameter tensioning thread wheel, and a steel wire rope connected with a lead or a carrier cable is wound outside the small-diameter tensioning thread wheel; the inner tooth ratchet wheel is fixedly connected with the bracket; and the fly wheel is fixedly connected with the spindle. The invention can thoroughly avoid the clamping and the eccentric wear of the steel wire ropes.

Description

technical field [0001] The invention relates to a catenary compensation device for an electrified railway, in particular to a broken line brake locker and a catenary compensation device with the brake locker. Background technique [0002] At present, the wires and catenary cables of the catenary compensation devices for electrified railways all over the world are connected with various types of compensation devices by steel wire ropes. The gravity of the heavy weight or the spring force of the spring compensation device will form a strong pulling force, which will instantly pull the broken catenary to one side of the compensation device, causing a vicious accident of broken wires and broken wires, forcing the train to stop running. [0003] A side brake ratchet tension compensation device for electrified railway catenary is disclosed in the Chinese patent database, its publication number: CN101695907, application date: 2009.10.30, publication date: 2010.04.21; The movable s...
