Background

In the contact net system of the electrified railway, in order to ensure the position of a contact line in space, a large number of contact line locators are used, one end of each locator is fixed on a locating pipe connected with a wrist arm through a locator base, and a locating sleeve at the other end of each locator fixes the contact line through a locating wire clamp.

The existing positioning wire clamp mainly comprises a wire clamp plate, a positioning pin, a U-shaped pin, a fastening bolt and other parts. When the device is used, the two wire clamping plates clamp the contact wire through the two fastening bolts, and then the two wire clamping plates are connected with the positioning sleeve on the positioner through the positioning pin which can freely rotate in the two wire clamping plates, so that the space positioning of the contact wire is formed.

When a positioning wire clamp is installed between the positioning sleeve and the contact wire, a bolt is required to be threaded, a nut is required to be installed, and a torque wrench is required to be used for fastening, so that time and labor are wasted.

Because the contact net has elasticity, the contact net can vibrate under the action of the pantograph when the train runs. Particularly, the high-speed rail has high travelling speed and the contact net vibrates more violently. Operation practices show that the positioning wire clamp with the structure has certain potential safety hazards, firstly, the movable part is easy to wear, and the part which is worn seriously for a long time is easy to break. Secondly, the fastening bolt is easy to loosen, the clamping force of the wire clamp is reduced after the bolt is loosened, and the contact line is easy to fall off if measures are not taken in time. The wire clamp is broken and the contact wire falls off to cause serious driving accidents. In order to prevent the accidents, a large amount of manpower and material resources are needed to be invested in the operation process to supervise and check the operation state of key stressed parts such as the positioning wire clamp and the like, and the operation cost is increased.
