Specific embodiment
The present invention will be further described in the following with reference to the drawings and specific embodiments.As shown in Figure 1, a kind of rail vehicle connects
Ground device, including grounding arm 16,16 upper end of grounding arm is connected to by height adjustment device on vehicle frame 1, and 16 lower end of grounding arm leads to
It crosses link block 12 to connect with contact 8,8 lower section of contact is provided with the conducting ring 7 being fixed on axle 3, and contact 8 is high in grounding arm 16
Degree contacts when declining with conducting ring 7；It is connected between grounding arm 16 and contact 8 by cable 14.
The earthing or grounding means 5 can coordinate the job state of vehicle operation device to use, for example, when low speed operation, use
Earthing or grounding means 5, regulated ground arm 16 decline, and contact 8 is made to be contacted with conducting ring 7, form grounded circuit.Work as high-speed cruising state
When, regulated ground arm 16 rises, and disconnects earthing or grounding means, can greatly reduce the abrasion of contact and conducting ring in this way, improves ground connection
The service life of device.
As shown in Fig. 2, the height adjustment device in first embodiment includes motor 22；Motor 22 is fixed on vehicle frame 1 vertically
On, it is fixedly connected with leading screw 20 below shaft；16 side of grounding arm is provided perpendicular to the sliding slot 17 of vehicle frame 1, leads to
It crosses sliding slot 17 to be slidably connected with the sliding bearing 19 being fixed on vehicle frame 1,16 top of grounding arm is provided with blind hole, is equipped in blind hole
With 20 matched internal thread of leading screw；It is connected between vehicle frame 1 and grounding arm 16 also by cable 14.
Leading screw is formed between grounding arm 16 and leading screw 20 --- nut linear movement is secondary, the output shaft of leading screw 20 and motor 22
It is fixedly connected, motor 22 is fixedly mounted in upper cover 21, and upper cover 21 is fixedly connected on vehicle frame 1, grounding arm 16 and sliding bearing
19 connections, sliding bearing 19 are fixed on vehicle frame 1, and motor 22 can pass through leading screw 20 --- nut and grounding arm 16, link block
12 grades band moving contact 8 moves up and down.Specially：In low speed job state, leading screw 20 is driven to rotate by motor 22 so that nut
It moves downward so that contact 8 is contacted with conducting ring 7, vehicle frame is in ground state；When high-speed cruising state need not be grounded, pass through
Motor drives leading screw 20 to rotate so that nut moves upwards so that contact 8 is not contacted with conducting ring 7.
The latch 18 that grounding arm 16 is prevented to rotate is additionally provided between the sliding bearing 19 of the present embodiment and sliding slot 17.
