Description

Technical Field

[0001] This utility model relates to the field of rail vehicle technology, and in particular to a rail vehicle connection and fixing device and a rail vehicle. Background Technology

[0002] In recent years, double-decker car transport vehicles have been increasingly used for loading and unloading cars at railway and highway level crossings. The use of railcars for loading and unloading cars is also becoming more frequent. Railcars are connected to the rails via guide wheels under a hydraulic guide device. However, because railcars at railway and highway level crossings lack longitudinal restraint along the rails, they can still shift even when fixed in place, posing a safety hazard.

[0003] Chinese Patent No. CN221233751U discloses a railcar connection and fixing device and a railcar, relating to the field of railcar technology. The railcar connection and fixing device includes a fixing component and a clamping component. One end of the fixing component is connected to the hydraulic guide device of the railcar, and the other end is hinged to the clamping component. The clamping component has a clamping cavity for clamping the rail at its end away from the fixing component, thus connecting the clamping component to the rail. This invention, by setting a clamping component and a fixing component between the hydraulic guide device of the railcar and the rail, with one end of the fixing component hinged to the clamping component and a clamping cavity at the end of the clamping component away from the fixing component, clamps the rail. When the railcar needs to be fixed to the rail, the clamping component rotates about the hinge point as an axis in the direction of the rail, clamping the railcar, fixing component, clamping component, and rail together, thus fixing the railcar to the rail, preventing displacement of the railcar, and avoiding safety hazards.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: When using the above-mentioned link fixing device, the railcar needs to be stopped first, and then the clamping structure needs to be manually adjusted to achieve the fixing effect of the railcar. In actual use, each railcar needs to be manually fixed, which reduces the fixing efficiency of the above-mentioned device. Utility Model Content

[0034] The following is combined with Figure 1-6 The utility model is described in further detail. Example 1

[0035] like Figures 1-6 As shown, in order to solve the existing problems, this utility model discloses a railcar connection and fixing device and a railcar, including a base 1 and a limiting member 2 connected to its side. A rotating bracket 3 is connected to the bottom of the base 1, a support plate 4 is connected to the top of the base 1, a housing 5 is connected to the top of the support plate 4, and a plurality of positioning holes 6 are provided on the top of the support plate 4.

[0036] A connector 7 is connected to the side of the base 1, and a docking member 8 is connected to the end of the connector 7 away from the base 1. A docking member 12 is connected to the other side of the base 1.

[0037] The rotating bracket 3 is rotatably connected to a rotating shaft 11, and a track wheel 10 is connected to the outer arc surface of the rotating shaft 11. The track wheels 10 are symmetrically arranged on both sides of the bottom of the base.

[0038] The docking component 12 includes a docking bracket 1201 connected to the side of the base 1. A rotating abutment 1202 is rotatably connected to the side of the docking bracket 1201 away from the base 1. One end of the rotating abutment 1202 is provided with an arc-shaped groove 1203. An elastic telescopic column 1204 is connected to the outside of the docking bracket 1201. A manual control lever 1205 is slidably connected to the end of the elastic telescopic column 1204 away from the docking bracket 1201.

[0039] Furthermore, a sliding member 1206 is slidably connected to the inner wall side of the docking bracket 1201, and a spring 1207 is connected to the side of the sliding member 1206. The other end of the spring 1207 is connected to the docking bracket 1201. A through hole is provided on the side of the docking bracket 1201, and the elastic telescopic column 1204 faces the through hole. The side of the sliding member 1206 blocks the through hole.

[0040] Specifically, the outer surface of the docking component 8 is provided with a wear-resistant layer, and the docking component 8 is provided with a through hole, the diameter of which is the same as the diameter of the through hole on the side of the docking bracket 1201.

[0041] The limiting member 2 is L-shaped and is symmetrically distributed on both sides of the base 1. The bending direction of the symmetrical limiting member 2 is towards the center of the base 1.

[0042] The specific working principle is as follows: This device can effectively improve the running stability and docking efficiency of the railcar. Compared with traditional devices, this device can effectively improve the connection efficiency.

[0043] When this device is in use, multiple sets of railcars are placed in succession, and then one railcar is moved to collide with another railcar.

[0044] When the two railcars collide, the docking piece 8 contacts the rotating abutment 1202 inside the docking bracket 1201 of the other railcar. The arc-shaped groove 1203 of the rotating abutment 1202 ensures stable contact between the rotating abutment 1202 and the docking piece 8. As the docking piece 8 enters the docking bracket 1201, the rotating abutment 1202 rotates due to the pressure exerted by the docking piece 8 on the rotating abutment 1202. This rotation causes the sliding piece 1206 to slide. The arc-shaped sides of the sliding piece 1206 and the rotating abutment 1202 ensure stable sliding of the sliding piece 1206 when the rotating abutment 1202 presses against it. The sliding groove 1208 limits the sliding process of the sliding piece 1206, preventing tilting and other problems. At this time, the sliding piece 1206 blocks the elastic telescopic column 1204 on the side of the through hole.

[0045] As the docking piece 8 extends into the rotating abutment 1202 continues to rotate, the sliding piece 1206 continues to slide inward, eventually causing the side through hole of the docking piece 8 to align with the side through hole of the docking bracket 1201. At this point, the elastic telescopic column 1204 is no longer obstructed, and the manual control rod 1205 extends into the through hole, thereby achieving the locking effect on the docking piece 8.

[0046] When it is necessary to unlock this device, the manual control lever 1205 is pulled outward by hand, thereby unlocking the device. At the same time, the spring 1207 drives the slider 1206 to slide outward, which can realize the automatic separation effect of the docking part 8 and the docking bracket 1201, reducing the operation difficulty of this device. Meanwhile, the slider 1206 automatically blocks the elastic telescopic column 1204. Example 2

[0047] like Figures 1-6 As shown, in order to solve the existing problems in this embodiment, based on the same concept as the first embodiment above, the railcar connection and fixing device and the railcar further include: a mudguard 9 is connected to the side of the rotating bracket 3, the mudguard 9 is disposed on the side of the rail wheel 10, and the mudguard 9 is detachably connected to the rotating bracket 3.

[0048] The base 1 has a reinforcing member at its bottom, and the side of the reinforcing member is connected to the support plate 4.

[0049] The specific working principle is as follows: This device can achieve the effect of automatic locking after docking and impact, thereby achieving a rapid connection during the connection process. At the same time, this device has a manual unlocking structure, which facilitates the efficiency of subsequent unlocking and disconnection operations.

[0050] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
