Embodiment Construction

[0009] The present invention will be further described below with reference to the accompanying drawings: Cartesian coordinate axes set for convenience of description: X direction is the forward direction of the locomotive, Z direction is vertically upward, and XOY is the coordinate axis seen downward from the positive direction of the Z axis .

[0010] The gyro directional platform is composed of two parts, and the substrate is made into a zigzag shape to save space. The first part is a damping platform, which is installed on the four corners of the base plate 1, symmetrical to the X-axis and Y-axis, and consists of four air springs 2, four hydraulic shock absorbers 3 and four stoppers 4 , their upper ends are installed on the base plate, and their lower ends are installed on the roof plate 10 of the electric locomotive, and they are arranged in the direction of crossing lines at four corners. The limiter 4 limits the movement of the substrate 1 within a safe range. The adv...

Abstract

The invention provides a gyro directional platform for a pantograph of an electric locomotive, which belongs to the technical field of electrified railways. The technical problem of stability in operation of electric locomotive pantographs troubles the railway operation department for long. Limiters, oil pressure dampers and air springs are sequentially arranged in the direction of four corner intersection lines of a platform base plate from outside to the center, the air springs and the oil pressure damper are arranged between a top plate of the electric locomotive and the platform base plate, the limiters are mounted on the top plate of the electric locomotive, a gyro directional device consists of two X-axially mounted gyros with the Y-axis serving as the axis of symmetry and two Y-axially mounted gyros with the X-axis serving as the axis of symmetry, and the pantograph is mounted on the platform base plate through four insulators. Rigidity of the air springs can be changed by adjusting inflating pressure to enable optimal damping effect of the pantograph in the Z direction, a damping platform provides degrees of freedom for the gyro directional device in movement, and the pantograph is kept avoiding rotating around the X-axis and the Y-axis, so that off line is reduced, and current collection quality can be improved. The gyro directional platform is mainly used for mounting pantographs.

Description

technical field [0001] The invention belongs to the technical field of electrified railways, in particular to the technology for stable operation of electric locomotive pantographs. Background technique [0002] The pantographs of existing electric locomotives at home and abroad are rigidly installed on the roof of the electric locomotive through insulators. The vibration caused by the unevenness of the line is directly transmitted to the pantograph, and some vibrations are also amplified by levers. Although the pantograph has a pressure of 70N on the contact wire, there is also a certain off-line at high speed, which will accelerate the loss of the contact wire and pantograph and reduce the quality of the current, which is one of the important factors restricting the increase in driving speed. Some countries have tried to install the pantograph on the locomotive bogie through a gantry, but due to the limitation of space on both sides of the locomotive, good results cannot b...
