Compression connecting device capable of accurately controlling press-in amount of dropper of railway pantograph-catenary system

Abstract

The invention discloses a compression connecting device capable of accurately controlling the press-in amount of a dropper of a railway pantograph-catenary system. The compression connecting device comprises a substrate and a loading mechanism. A front baffle, a linear bearing cushion block, a semi-open type linear bearing cushion block and a rear baffle are sequentially fixed to the substrate. The loading mechanism comprises a loading lead screw. The loading lead screw is in threaded connection with the front baffle and a bearing sleeve in sequence. The bearing sleeve is embedded into one end of a thrust bearing, and the other end of the thrust bearing is connected with a force bearing rod in an interference fit mode. The force bearing rod penetrates through the linear bearing cushion block and the semi-open type linear bearing cushion block and connected with a movable compression connector in a clearance fit mode; a fixed compression connecting head is fixed to the position directly facing the movable compression connector; and a compression connecting pipe used for compression connecting of the dropper is arranged between the movable compression connecting head and the fixed compression connecting head. The compression connecting device is specially designed for compression connecting force and the press-in amount of the dropper, is simple in structure, convenient to operate, capable of achieving accurate control over the compression connecting force and the press-in amount of the dropper and high in practicability and generalization performance.

Description

technical field [0001] The invention belongs to the technical field of crimping of railway hanging strings, and in particular relates to a crimping device for precisely controlling the pressing amount of hanging strings of a railway pantograph-catenary system. Background technique [0002] High-speed railway (hereinafter referred to as high-speed railway) has become an important direction for the development of rail transportation due to its many advantages such as fast speed, high efficiency, energy saving and environmental protection, safety and comfort. Especially in the past ten years, with the rapid economic and social development, China's high-speed rail has achieved leapfrog development, and has led to a new round of high-speed rail construction in the world. As of September 2016, the total mileage of China's high-speed rail has exceeded 20,000km, and the world's largest high-speed rail network has been built. However, with the continuous increase of the high-speed r...
