Description

Technical Field

[0001] The utility model relates to the technical field of road contact network equipment, in particular to a vibration-damping contact network positioning bracket for high-speed railways. Background Art

[0002] The overhead line is a special form of transmission line that supplies power to electric locomotives along the railway line. It consists of contact suspension, support device, positioning device, support and foundation. As people continue to pursue higher speeds, the demand for railway reliability is becoming more urgent.

[0003] A Chinese utility model patent with application number 201720126340.8 proposes a position limiting and positioning device for an electrified railway contact network, comprising a positioning support and a limiter. The key technical point is that the positioning support comprises an upper vertical portion, a lower vertical portion and an inclined connecting portion connecting the upper vertical portion and the lower vertical portion, a fixing piece is arranged at the end of the upper vertical portion, and an arc-shaped limit plate and a positioning ring are fixedly arranged on the side of the lower vertical portion from top to bottom; a positioning pin sleeve is fixedly connected to one end of the limiter, a positioning wire clamp is fixedly connected to the lower end of the positioning pin sleeve, an adjustment limit screw corresponding to the arc-shaped limit plate is assembled at the other end of the limiter, and a positioning hook matching the fixing piece is arranged at the lower part, and the limiter is a scimitar-shaped limiter. The lifting amount of the limiter in the position limiting and positioning device can be adjusted and changed according to the use requirements, and the installation space of the positioning support is increased according to the shape adjustment, which can meet the installation requirements of space-restricted occasions.

[0004] After the improvement, the lifting amount of the limiter in the limit positioning device can be adjusted and changed according to the use requirements, and the installation space of the limiter can be increased according to the shape adjustment, which can meet the installation requirements of space-constrained occasions. However, during use, there is no structure to adjust the tightness of the traction rope. After long-term use, the traction rope will become looser and looser, resulting in the inability to keep the traction rope taut, thereby reducing its traction force and further reducing its stability in positioning the contact network. For this reason, we propose a vibration-damping contact network positioning bracket for high-speed railways. Utility Model Content
