[0047] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0048] Reference below Figure 1-Figure 3 A grounding device 10 for a rail vehicle according to an embodiment of the present invention is described.

[0049] According to the rail vehicle of the embodiment of the present invention, the rail vehicle can be movably matched with the track beam 20, at least part of the track beam 20 is an elevated beam, and the track beam 20 is provided with a ground rail 203 and a track beam baffle 204. Such a configuration enables the rail vehicle to run normally on the track beam 20.

[0050] like Figure 1-Figure 3 As shown, the grounding device 10 according to the embodiment of the present invention comprises: an anti-rollover baffle 1 and a grounding shoe 2. The anti-rollover baffle 1 is installed on the housing of the drive axle, and the end of the anti-rollover baffle 1 is located below the track beam baffle 204. It can also be understood that in the up and down directions, the projection of the anti-rollover baffle 1 and the projection of the track beam baffle 204 have an overlapping part. In this way, when the rail vehicle tilts, the anti-rollover baffle 1 and the track beam baffle 204 can be stopped together to prevent the rail vehicle from rolling over.

[0051] The grounding shoe 2 is arranged below the end of the anti-rollover baffle 1, and the grounding shoe 2 is used to contact the grounding rail 203, and the grounding rail 203 is electrically connected to the earth, so that the leakage of the rail vehicle can be guided to the ground. When the guide wheel of the rail vehicle is under-voltage, the grounding shoe 2 can contact the grounding rail 203, and this arrangement can prevent the rail vehicle from moving laterally on the track beam 20. It should be noted that the lateral direction refers to Figure 1 In the left and right directions, the problem of grounding failure caused by the lateral movement of the rail vehicle can be prevented, and the installation can be convenient, eliminating a large number of grounding shoe 2 installation devices, thereby ensuring the driving safety of the rail vehicle. In addition, the grounding device 10 has a small size and a simple structure, which can save the manufacturing cost of the rail vehicle.

[0052] Therefore, by cooperating with the track beam baffle 204, the anti-rollover baffle 1, the grounding shoe 2 and the grounding rail 203, the rail vehicle can be prevented from rolling over, and the installation can be convenient, eliminating a large number of grounding shoe 2 installation devices. Moreover, the grounding device 10 has a small size and a simple structure, which can save manufacturing costs.

[0053] In some examples of the present invention, the grounding rail 2 can be set as an integrally formed part with the track beam 20. The integrally formed part has high structural strength. Such a setting can prevent cracking at the connection between the grounding rail 2 and the track beam 20 and prevent the grounding rail 2 from falling off the track beam 20.

[0054] In some examples of the present invention, grounding shoes 2 may be provided below both ends of the anti-rollover baffle 1. It should be noted that only one grounding shoe can be installed on the existing guide frame, while two grounding shoes 2 may be provided below the anti-rollover baffle 1 of the present application, and such a configuration may improve the working performance of the grounding device 10, thereby further ensuring the driving safety of the rail vehicle.

[0055] In some examples of the present invention, Figure 2 and Figure 3 As shown, the grounding shoe 2 includes: a mounting seat 21 and a contact member 22. The mounting seat 21 is arranged below the end of the anti-rollover baffle 1, and the contact member 22 is arranged on the mounting seat 21, and the contact member 22 is arranged toward the grounding rail 203, and the contact member 22 is used to contact the grounding rail 203, wherein, when the guide wheel of the rail vehicle is under-voltage, the contact member 22 of the grounding shoe 2 can contact the grounding rail 203, and such an arrangement can better prevent the rail vehicle from moving laterally on the track beam 20.

[0056] In some examples of the present invention, the contact member 22 can be configured as an elastic member, which can return to its original shape after deformation, wherein when the contact member 22 contacts the grounding rail 203, the contact member 22 is squeezed and deformed, and when the contact member 22 does not contact the grounding rail 203, the contact member 22 returns to its original shape. Such a configuration can prevent the situation where the contact member 22 does not contact the grounding rail 203 after deformation, thereby further ensuring the working reliability of the grounding device 10.

[0057] In some examples of the present invention, the contact member 22 can be configured as a deformable copper member, which has a strong ability to resist deformation. When the copper member is not in contact with the grounding rail 203, the copper member can better restore to its original shape. Such a configuration can make the manufacturing material of the contact member 22 more reasonable, thereby improving the working reliability of the contact member 22.

[0058] In some examples of the present invention, the contact 22 may include a plurality of stacked copper sheets, which can improve the structural strength of the contact 22 and prevent the contact 22 from being damaged when squeezed, thereby extending the service life of the contact 22.

[0059] In some examples of the present invention, Figure 2 and Figure 3 As shown, the contact member 22 may include: an installation segment 221 and a contact segment 222, the installation segment 221 is fixedly connected to the mounting seat 21, and the contact segment 222 is used to contact the ground rail 203. This arrangement can make the design structure of the contact member 22 more reasonable and the contact member 22 can be better assembled on the mounting seat 21.

[0060] In some examples of the present invention, the orthographic projection of the contact segment 222 on the horizontal plane is an arc. Such a configuration can optimize the structure of the contact segment 222 and enable the contact segment 222 to reliably contact the ground rail 203 .

[0061] In some examples of the present invention, Figure 2 and Figure 3 As shown, there may be an arc transition section 23 between the mounting section 221 and the contact section 222. The arc transition section 23 has an arc. It should be noted that, in the case of Figure 3 In the example shown, the projection of the arc transition section 23 on the horizontal vertical plane is an arc shape. The arc transition section 23 has good smoothness and can avoid cracks at the connection between the mounting section 221 and the contact section 222. Such a setting can better connect the mounting section 221 and the contact section 222 together, and can improve the overall structural strength of the mounting section 221 and the contact section 222, thereby ensuring the working reliability of the contact member 22.

[0062] In some examples of the present invention, Figure 2 and Figure 3 As shown, the mounting seat 21 may include: a first plate 211 and a second plate 212, the first plate 211 and the second plate 212 are connected, the first plate 211 is fixedly connected to the anti-rollover baffle 1, and the mounting section 221 is fixedly connected to the second plate 212. This arrangement can firmly assemble the mounting seat 21 on the anti-rollover baffle 1, and can also firmly assemble the mounting section 221 on the second plate 212, which can prevent the anti-rollover baffle 1 and the contact member 22 from interfering with each other.

[0063] In some examples of the present invention, the first plate 211 and the second plate 212 can be arranged vertically. Such an arrangement can optimize the structure of the mounting base 21, improve the structural strength and rigidity of the mounting base 21, and thus prevent the connection between the first plate 211 and the second plate 212 from breaking.

[0064] In some examples of the present invention, Figure 2 and Figure 3 As shown, the grounding device 10 may further include: a pressing block 3, which is pressed on the outer side of the mounting section 221. It should be explained that the mounting section 221 is arranged between the pressing block 3 and the second plate 212. When the pressing block 3, the mounting section 221 and the second plate 212 are assembled together, the pressing block 3 can firmly press the mounting section 221 on the second plate 212, thereby making the position of the contact member 22 more stable.

[0065] In some examples of the present invention, the pressing block 3 can be set as an aluminum alloy pressing block 3. The manufacturing material source of the aluminum alloy pressing block 3 is wide. Such a setting can reduce the manufacturing cost of the pressing block 3, thereby further saving the manufacturing cost of the rail vehicle.

[0066] In some examples of the present invention, at least one of the pressing block 3 and the mounting segment 221 is provided with an anti-corrosion layer. It should be explained that only the pressing block 3 may be provided with an anti-corrosion layer, only the mounting segment 221 may be provided with an anti-corrosion layer, or both the pressing block 3 and the mounting segment 221 may be provided with an anti-corrosion layer. Such a setting can prevent electrochemical corrosion between the pressing block 3 and the mounting segment 221, and can avoid damage to the pressing block 3 and the mounting segment 221, thereby extending the service life of the pressing block 3 and the mounting segment 221, and further ensuring the working reliability of the pressing block 3 and the mounting segment 221.

[0067] In some examples of the present invention, the surface of the mounting section 221 may be plated with tin, and the tin layer may contain bismuth. This arrangement may better prevent electrochemical corrosion between the pressing block 3 and the mounting section 221 .

[0068] In some examples of the present invention, Figure 2 and Figure 3 As shown, the grounding device 10 may further include: a fastener 4, which is fastened after passing through the pressing block 3, the mounting section 221 and the mounting seat 21, wherein the pressing block 3, the mounting section 221 and the mounting seat 21 are assembled together by the fastener 4, so that the overall assembly structure of the pressing block 3, the mounting section 221 and the mounting seat 21 can be made more stable, thereby preventing the mounting section 221 from falling off the mounting seat 21.

[0069] In some examples of the present invention, Figure 2 and Figure 3 As shown, the grounding device 10 may further include: a lead wire 5, one end of which is fixedly connected to the second plate 212, and the other end of the lead wire 5 is led upward, wherein the lead wire 5 can transfer static electricity on the rail vehicle to ensure safe driving of the rail vehicle, and the terminal of the lead wire 5 should also be electrochemically anti-corrosive. Such a setting can prevent the lead wire 5 from being corroded, thereby extending the service life of the lead wire 5.

[0070] The rail vehicle according to the present invention includes the grounding device 10 of the rail vehicle of the above-mentioned embodiment. The grounding device 10 is arranged and installed on the rail vehicle. The rail vehicle can prevent the rail vehicle from rolling over and can also prevent the problem of grounding failure caused by the lateral movement of the rail vehicle. In addition, the grounding device 10 is small in size and simple in structure, which can save the manufacturing cost of the rail vehicle.

[0071] like Figure 1 As shown, the rail transit system according to the present invention includes: a track beam 20 and a rail vehicle of the above embodiment, and the rail vehicle is movably matched with the track beam 20. Such an arrangement allows the rail vehicle to run normally on the track beam 20.

[0072] In some examples of the present invention, the track beam 20 may include: a beam body 201 and a grounding rail 203. The beam body 201 is provided with a groove 202, the upper end of the groove 202 is open, and the edge of the upper end of the groove 202 extends a track beam baffle 204 toward the groove 202, and the grounding rail 203 is connected to the side wall of the groove 202, and the grounding rail 203 is located below the track beam baffle 204. The grounding rail 203 is used to contact the grounding device 10 of the rail vehicle of the above embodiment. The grounding rail 203 can be fixed to the side wall of the groove 202 by bolts, and such a setting can firmly assemble the grounding rail 203 on the groove 202, and can prevent the position of the grounding rail 203 from moving, thereby ensuring that the grounding rail 203 can contact the contact member 22 of the grounding device 10.

[0073] In some examples of the present invention, Figure 3 As shown, the ground rail 203 includes: a straight section 2031 and a tapered section 2032, and the straight section 2031 is connected to the tapered section 2032. This arrangement can better connect the straight section 2031 and the tapered section 2032 together, thereby preventing the straight section 2031 and the tapered section 2032 from separating.

[0074] In some examples of the present invention, the thickness of the straight section 2031 can be set to 9-11 mm, for example, the thickness of the straight section 2031 can be set to 10 mm. Such a setting can make the design thickness of the straight section 2031 more reasonable, improve the structural strength of the straight section 2031, and prevent the straight section 2031 from deforming when it contacts the contact piece 22.

[0075] In some examples of the present invention, the thickness of the tapered section 2032 gradually decreases in the direction from the connection between the tapered section 2032 and the straight section 2031 to the end of the tapered section 2032, wherein when the contact piece 22 is located at the end of the tapered section 2032, the contact piece 22 will not contact the grounding rail 203. Such a setting can make the design structure of the tapered section 2032 more reasonable.

[0076] In some examples of the present invention, the end thickness of the tapered section 2032 is 3-5 mm. For example, the end thickness of the tapered section 2032 can be set to 4 mm, wherein the end thickness of the tapered section 2032 is the minimum thickness of the tapered section 2032. Such a setting can make the design thickness of the tapered section 2032 more reasonable and ensure the structural strength of the tapered section 2032.
