Specific embodiment
With reference to specific embodiment, the present invention will be described in detail.
A kind of electrification railway contact net bracket shaft device of the present invention, including with overall bracket 15 consolidate
The upper axle bed and lower axle bed set on vertical shaft 8 and pillar side wall unsplit bedplate 14.Vertical shaft 8 is square steel tube, length of side 60mm, wall
Thick 5mm.Overall bracket 15 is consolidated in square steel tube side wall, is arranged on unsplit bedplate by shaft device.
Upper axle bed includes holding screw 1, deep groove ball bearing 4, self-lubricating bearing 6, inner thread sleeve 7, and inner thread sleeve 7 is inserted
The top of vertical shaft 8 is accessed, inner thread sleeve external diameter 50mm is connected using welding or flange connection.Holding screw 1 is by deep-groove ball
Bearing 4 and self-lubricating bearing 6 are connected on inner thread sleeve 7.The self-lubricating bearing 6 of upper axle bed is located in the upper end support of bearing 5.
The top of the upper end support of bearing 5 is provided with upper end cover 3, and deep groove ball bearing 4 is located between the upper end support of bearing 5 and upper end cover 3.Upper axle
Seat is installed on unsplit bedplate 14 by the bolt component on the upper end support of bearing 5.
