Detailed Description

The present utility model will be described in detail below with reference to the embodiments shown in the drawings, but it should be understood that the embodiments are not limited to the present utility model, and functional, method, or structural equivalents and alternatives according to the embodiments are within the scope of protection of the present utility model by those skilled in the art.

Referring to fig. 1 to 5, there is shown an embodiment of a grounding device for a suspended monorail vehicle according to the present utility model.

A ground-engaging device for a suspended monorail vehicle 3 for the ground-engaging of the vehicle 3, comprising: the upright post 1 is connected with the grounding grid; the track beam 2 is arranged at the top end of the upright post 1 and used for suspending a vehicle body, and the track beam 2 is electrically connected with the upright post 1; further comprises: the grounding brush 4 is fixedly arranged on the bogie of the vehicle body, the outer end of the grounding brush 4 is flexibly contacted with the inner wall of the track beam 2, and the grounding brush 4 is used for conducting electricity after the vehicle body is contacted with the track beam 2. The grounding brush 4 comprises a mounting frame 41 and a flexible conductive part 42, wherein the mounting frame 41 is fixedly arranged on the bogie, one end of the flexible conductive part 42 is fixedly connected with the mounting frame 41, and the other end of the flexible conductive part is always in contact with the inner wall of the track beam 2. The grounding brush 4 can be mounted in any orientation of the bogie as long as it is ensured that the grounding brush 4 can be kept in good contact with the inner wall of the track beam 2 while the vehicle 3 is running! The flexible conductive portion 42 is made of conductive rubber, and a portion of the conductive rubber may be replaced by another flexible conductive material. The mounting frame 41 includes: the first support plate and the second support plate which are horizontally arranged at intervals are connected with the connecting piece 410 between the first support plate and the second support plate, the connecting piece 410 penetrates through the bogie to be arranged, the clamping ends for clamping the flexible conductive parts 42 are formed between the first support plate and the second support plate in a surrounding mode, and the flexible conductive parts 42 are fixedly clamped by the clamping ends. The flexible conductive part 42 is fixedly connected with the clamping end through a rivet 420.

In the implementation manner, since the track beam 2 and the upright 1 of the suspended monorail vehicle 3 are both made of steel materials, the vehicle 3 can be grounded through the grounding brush 4 as long as the track beam 2 and the upright 1 are electrically connected and the upright 1 is grounded. The grounding brush 4 needs to be in contact with the inner wall of the rail beam 2, and is kept in flexible contact with the inside of the rail beam 2 when the vehicle 3 is running, and the grounding brush 4 can conduct electricity after being in contact with the inside of the rail beam 2 because the inner wall of the rail beam 2 is a metal surface. When the electric leakage occurs in the vehicle 3, the leakage current flows to the grounding brush 4 and then flows to the grounding grid through the track beam 2 and the upright post 1, so that the electrification of the vehicle body can be avoided. Further, the electric leakage detection protection device 5 can be arranged in the power supply station area, when electric leakage occurs in the vehicle 3, the electric leakage can be detected through the ground grid backflow, so that the power supply of the power supply rail can be disconnected in time, and the safety is ensured.

Furthermore, it should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is provided for clarity only, and that the disclosure is not limited to the embodiments described in detail below, and that the embodiments described in the examples may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
