Pantograph sliding plate airway cutting device and cutting method thereof

Abstract

The invention discloses a pantograph sliding plate air duct cutting device. The pantograph sliding plate air duct cutting device comprises a support plate and multiple stand columns, wherein the multiple stand columns are arranged at the lower end of the support plate in a supporting manner. Sliding barrels are vertically connected to the upper end of the support plate in an inserted manner. A sliding sleeve is mounted in each sliding barrel in a sliding manner. A stepping motor is vertically mounted in each sliding sleeve. A threaded rod is mounted on an output shaft at the lower end of eachstepping motor. The pantograph sliding plate air duct cutting device and a cutting method thereof have the beneficial effects that by means of the pantograph sliding plate air duct cutting device andthe cutting method thereof, cutting blades can be automatically controlled to descend; in addition, the descending speed of the cutting blades is adjustable; the problem that due to the excessively-high descending speed of the cutting blades, annular grooves are cut to be excessively deep and cannot be used is effectively avoided; in addition, by means of the method, the functions that the multiple annular grooves are formed in an integral copper pipe through one-time cutting can be achieved; the cutting speed can be remarkably increased, and the cutting efficiency can be remarkably improved;and the pantograph sliding plate air duct cutting device is easy and convenient to operate and good in practicability, and time and labor are saved.

Description

technical field [0001] The invention relates to the field of pantograph slides, in particular to a pantograph slide airway cutting device and a cutting method thereof. 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 p...
