Device and catenary to prevent weight from falling to the ground

Abstract

The invention relates to a device for preventing a weight from falling to the ground and a catenary net. The device for preventing a weight from falling to the ground includes a weight limiting tube, a connecting arm of the limiting tube, a constant force spring and a spring movable plate. A first socket is opened on the tube wall of the weight limiting pipe, and the weight limiting pipe is used for connecting to the weight limiting frame. The connecting arm of the limiting tube is inserted into the first insertion hole, and the connecting arm of the limiting tube is also provided with a first connecting hole for connecting the compensation rope. One end of the spring movable plate is connected to the weight restricting pipe through a constant force spring, and the other end of the spring movable plate is provided with a second connection hole, which is used to be connected to the weight rod. The spring movable plate is connected to the connecting arm of the restricting tube. Install a device to prevent the weight from falling to the ground on the catenary. In the event of a disconnection accident, it can effectively prevent the string of weights from falling, ensuring the safety of people and buildings. The staff does not need to re-stack the weights into strings, which is conducive to shortening the maintenance time.

Description

technical field [0001] The invention relates to the technical field of electrified railway power supply, in particular to a device for preventing a weight from falling to the ground and a catenary. Background technique [0002] At present, in the event of broken rods, bow scraping, tripping, thunderstorms, etc., the contact wire or load-bearing cable of the electric railway catenary will be broken, resulting in slack in the compensation rope. Losing balance, the weight falls to the ground and disperses under the force of gravity. During the rush repair process, the staff need to re-stack the scattered weights into strings, which is difficult to restore and requires a long working time, which is an important factor restricting the timely resolution of accidents such as disconnection and collapse of the net. Especially when the anchor joint of the railway catenary is located on the bridge, once the catenary is disconnected, the weight will fall under the bridge, which will en...

Problems solved by technology

[0002] At present, in the event of broken rods, bow scraping, tripping, thunderstorms, etc., the contact wire or load-bearing cable of the electric railway catenary will break, resulting in slack in the compensation rope. Loss of balance, the weight falls to the ground and spreads out under the force of gravity

During the rush repair process, the staff need to re-stack the scattered weights into strings, which is difficult to restore and requires a long working time, which is an important factor that restricts the timely resolution of accidents such as disconnection and collapse of the net

Especially when the anchor joints of the railway catenary are set on the bridge, once the catenary is disconnected, the weight will fall under the bridge, which will endanger the safety of buildings and people under the bridge, which has great potential safety hazards
