Airway girdling device of pantograph slider

Abstract

The invention discloses an airway girdling device of a pantograph slider. The airway girdling device comprises a clamping seat of which the top is provided with a clamping slot, and the clamping slotis internally provided with two clamping blocks movably; the both sides of the clamping seat are fixedly provided with supporting seats, and the top of each supporting seat is fixedly provided with aclamping cylinder of which the output end is fixedly provided with a portable pillar arranged horizontally; the inner walls of the both sides of the clamping slot are provided with through holes; andthe end, far away from the clamping cylinder, of the portable pillar movably penetrates through the corresponding through hole, extends into the clamping slot, and is fixedly connected to the corresponding clamping block. The airway girdling device is simple in structure, and easy to operate; through the locking function of a threaded locating pipe and a locating slot, an airway copper pipe can beclamped and fixed between the two clamping blocks firmly, thereby facilitating subsequent cutting of the airway copper pipe; the airway copper pipe is prevented from axially swinging in the cutting process, and the using requirements of people are met.

Description

technical field [0001] The invention relates to the field of pantograph slide processing, in particular to an airway circumcision device for a pantograph slide. Background technique [0002] The pantograph slide is a key component for the safe operation of electric locomotives. During the operation of the locomotive, the pantograph slide plate is in contact with the catenary and has a high-speed relative motion, and is constantly subjected to high-speed impact and frequent vibration of the catenary. In order to ensure safe operation, the electric locomotive adopts an automatic lowering system of the pantograph. The basic principle is to set an air passage (usually copper pipe) in the slide plate, and the air source system supplies compressed air to it from the pantograph. . When the slide plate breaks, the air passage is damaged accordingly, and the compressed air leaks from the air passage of the slide plate, and the fast lowering valve will remove the air in the pantogra...
