Double-bow cut-off device for detecting pantograph pressure of engine

Abstract

The invention relates to a double-bow cut-off device for detecting pantograph pressure of an engine. An installation rack is fixed at the inner side of a stand column at the outer side of a track, and is fixedly connected with the cut-off device through an insulative connecting rack. The concrete structure of the cut-off device is that: a working platform is fixedly connected with the connecting rack, the bottom of the working platform is fixedly provided with a transverse sliding rail; a transverse sliding seat is sleeved on the transverse sliding rail, a screw at the middle lower part of a vertical lifting rod is connected in a screw nut of the transverse sliding seat, the lower end of the lifting rod is connected with the outer ring of a bearing through a flange, the inner ring of the bearing is fixedly connected with the upper end part of a connecting rod; and the lower end of the connecting rod is connected with a longitudinal slide block, and a longitudinal slide block at the upper part of a contact network clip is sleeved on the longitudinal slide block. When contact pressure detection is carried out on more than two pantographs, the double-bow cut-off device can be utilized to eliminate the mutual interference between adjacent pantographs, thereby enabling the detection result to be more reliable and more accurate.

[0001] The invention relates to a double-bow cut-off device for locomotive pantograph pressure detection. Background technique

[0002] In the high-speed electrified railway system, the locomotive must maintain a stable current receiving state, which requires a certain contact pressure between the pantograph and the contact wire: when the contact pressure is too small, it is easy to cause offline, that is, the pantograph is separated from the contact wire and Arcing occurs; when the contact pressure is too large, the lift of the contact wire is too large, causing the contact wire to be partially bent, causing fatigue damage to the contact wire, and at the same time increasing the wear of the contact wire, causing pantograph-catenary accidents in severe cases. my country's locomotives, especially the newly opened high-speed EMUs, have the characteristics of high density, long running mileage, complex operating environment, and different operating speed levels....
