Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention.
As shown in fig. 1 to 2, the parking brake electric auxiliary remote relieving mechanism for a rail transit vehicle of the present embodiment includes: the device comprises a steel wire rope 1, a mounting base 3, an electric push rod module 10, a pull rod 9, a driver 4, a handle 7, a dust cover 2, a spring pin 6 and the like. Wherein, the steel wire rope jacket 1-1 is connected with the installation base 3 through screw threads and is locked through a nut 14. The steel wire rope inner core 1-2 passes through the driver 4, the dust cover 2 and the handle 7 and is limited by a second end nut 15. The driver 4 can slide over the wire rope core 1-2 and is retained by a first end nut 11, see fig. 2. The inner groove of the driver 4 is provided with a dustproof and waterproof O-shaped rubber ring 12; two ends of the dust cover 2 are respectively fixed with the driver 4 and the rope jacket 1-1 by adopting a nylon cable tie 13. Two ends of the pull rod 9 are respectively connected with the driver 4 and a driving ejector rod of the electric push rod module 10, and one end of the pull rod 9 connected with the driving ejector rod is prevented from falling off through the cotter pin 8. The spring pin 6 penetrates through the mounting seat 3 and the handle 7 to realize safe locking, and the spring pin 6 is connected with the mounting base through the rubber rope 5.
In this embodiment, the mounting base 3 is formed by a metal plate and used for fixing the steel wire rope 1, and mounting the electric push rod module 10 and the fixed spring pin 6.
The pull rod 9 is used for transmitting the output force of the electric push rod module 10 to the driver 4, and the hook-shaped structure at the tail end of the pull rod 9 penetrates through the hole of the driver 4 without being fixed by other parts, as shown in fig. 3.
The driver 4 can slide on the rope core and is limited by the first end nut 11, and is used for driving the rope core 1-2 to do linear motion and isolating the blocking influence of the pull rod 9 when in manual operation.
