Description

Technical Field

[0001] This utility model relates to the field of tooling structures, specifically to a rail transit vehicle dispatching and securing device. Background Technology

[0002] After the new subway cars are manufactured, they can be transported to various train depots via return transport. However, after the new A-type and B-type subway cars are manufactured, since the main engine manufacturers do not have lines connecting to the various train depots, they can only be transported by road. During road transport, the car body and bogies need to be hoisted onto the transport vehicle as a whole. Since the vehicle does not have a special fixing ring, it cannot be connected to the car. Furthermore, the car body traction seat assembly on the vehicle has a special shape, different inclination, and no connecting holes, which makes it impossible for the transport vehicle and the subway car to be directly connected through the traction seat. This can easily lead to displacement of the vehicle, deformation of the outer shell, or scratches on the paint. Utility Model Content

[0003] The technical problem this utility model aims to solve is that Type A subways, Type B subways, and urban rail trains cannot be directly connected to the transport vehicle via a tethering seat during road transport, resulting in deformation of the subway vehicle's shell or scratches on its paint. The purpose is to provide a rail transit vehicle dispatching and securing device, so that when transporting subway vehicles, a securing ring connected to the car body tethering seat assembly can be used to connect the subway vehicle to the vehicle, thereby preventing displacement of the subway vehicle and preventing deformation of the subway vehicle's shell or scratches on its paint.

[0004] This utility model is achieved through the following technical solution:

[0005] A rail transit vehicle dispatching and securing device includes a securing ring body and a pad. The securing ring body has a hook-shaped portion at one end and a threaded portion at the other end. A securing plate is located in the middle of the securing ring body. In the working state, the securing plate abuts against the inclined plate of the car body traction seat assembly. The hook-shaped portion is located on the outside of the car body traction seat assembly. The pad has a through hole for the threaded portion to pass through. The threaded portion passes through the inclined plate of the car body traction seat assembly, the flat plate of the car body traction seat assembly, and the securing plate in sequence before being screwed into a locking nut.

[0006] The beneficial effects of this utility model are that by providing a hook-shaped part on the main body of the fastening ring, a threaded part on the other end, and a fastening plate in the middle of the main body of the fastening ring, the strength of the fastening ring body is ensured. It also facilitates the installation of the fastening ring body on the car body traction seat assembly. First, the threaded part passes through the inclined plate, the flat plate and the fastening plate of the car body traction seat assembly in sequence and then screws into the locking nut. The fastening plate abuts against the inclined plate of the car body traction seat assembly, so as to firmly connect the fastening ring body to the car body traction seat assembly. The hook-shaped part is located on the outside of the car body traction seat assembly, so that when transporting the subway car, the fastening ring connected to the car body traction seat assembly can be connected to the subway car to prevent the subway car from shifting and prevent the subway shell from deforming or the paint from being scratched.

[0007] In some embodiments, the fastening ring body is U-shaped, and the fastening plate is inclinedly disposed in the middle of the fastening ring body. The inclination direction of the fastening plate is the same as the inclination direction of the inclined plate of the vehicle body towing seat assembly. A closed hanging ring is formed between the hook-shaped portion and the fastening plate. By providing a fastening plate on the U-shaped fastening ring body and forming a closed hanging ring between the fastening plate and the hook-shaped portion, the strength and rigidity of the hanging ring are ensured.

[0008] In some embodiments, the system further includes a plurality of first gaskets located between the flat plate of the vehicle body towing seat assembly and the pad, with protective rubber provided on the side of the first gasket that contacts the vehicle body towing seat assembly. By providing the first gaskets between the flat plate of the vehicle body towing seat assembly and the pad, the protective rubber fills the gap through its own deformation, ensuring that there is no loose connection between the towing seat flat plate and the pad, and avoiding uneven bolt stress caused by gaps during fastening (such as some bolts not being tightened or some bolts being overloaded).

[0009] In some embodiments, the protective rubber is provided with several anti-slip protrusions evenly distributed on it. By providing anti-slip protrusions, the physical structure of the friction is increased, thereby improving the frictional stability between the protective rubber and the traction seat plate.

[0010] In some embodiments, the device further includes two reinforcing ribs, which are respectively disposed between the hook-shaped portion and the fastening plate, and located on both sides of the hanging ring. By providing two reinforcing ribs between the hook-shaped portion and the fastening plate, the strength and rigidity of the fastening ring body are improved.

[0011] In some embodiments, the fastening ring body further includes two support portions, each located at the lower end of the corresponding threaded portion and at the upper end of the fastening plate. In the working state, both support portions abut against the flat plate of the vehicle body towing seat assembly. By providing support portions, the strength and rigidity of the fastening ring body are further improved, enhancing the firmness of the connection to the vehicle body towing seat assembly.

[0012] In some embodiments, the system further includes several second gaskets, the thickness of which gradually decreases from one end to the other. Each second gasket has a through hole for the two supports to pass through. Several second gaskets are overlapped between the fastening plate and the ramp of the vehicle body towing seat assembly. By gradually decreasing the thickness of the second gaskets from one end to the other, the fastening ring body can be connected to ramps of the vehicle body towing seat assembly at different inclinations, thereby improving the versatility of the fastening ring body and ensuring the secure connection of the fastening ring body to the vehicle body towing seat assembly.

[0013] In some embodiments, the second pad is a rubber pad, and the thickness and tilt angle of each second pad may be different. Several anti-slip protrusions are evenly distributed on the side of the second pad that contacts the inclined plate of the vehicle body traction seat assembly. By providing several anti-slip protrusions on the second pad, the frictional stability between the protective rubber and the inclined plate of the traction seat is improved.

[0014] In some embodiments, protective rubber is provided on both the side of the stabilizing plate facing the hook-shaped portion and the outer side of the hook-shaped portion, and several anti-slip protrusions are evenly distributed on the protective rubber. By providing protective rubber on both the side of the stabilizing plate facing the hook-shaped portion and the outer side of the hook-shaped portion, the friction between the subway vehicle and the stabilizing ring body is increased, preventing displacement of the subway vehicle during transportation.

[0015] In some embodiments, the surfaces of the fastening plate, hook-shaped portion, pad, and support portion are all coated with anti-rust paint. The anti-rust paint prevents the fastening device from rusting, ensuring its strength and rigidity.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] 1. To achieve a secure connection between the lashing ring body and the car body traction seat assembly, and to position the hook-shaped part on the outside of the car body traction seat assembly, so that when transporting subway cars, the lashing ring connected to the car body traction seat assembly can be used to connect the subway car to the subway car, thereby preventing the subway car from shifting, deforming the subway car shell or scratching the paint.

[0018] 2. Protective rubber is provided on the side of the tethering plate facing the hook-shaped part and on the outside of the hook-shaped part to increase the friction between the subway car and the tethering ring body and prevent the subway car from shifting during transportation.

[0029] Example

[0030] like Figures 1-3 As shown, this embodiment provides a rail transit vehicle dispatching and securing device, including a securing ring body 10 and a pad 17. The securing ring body 10 is provided with a hook-shaped part 11 and a threaded part 16 at the other end. A securing plate 13 is provided in the middle of the securing ring body 10. In the working state, the securing plate 13 abuts against the inclined plate of the car body traction seat assembly. The hook-shaped part 11 is located on the outside of the car body traction seat assembly. The pad 17 is provided with a through hole for the threaded part 16 to pass through. The threaded part 16 passes through the inclined plate of the car body traction seat assembly, the flat plate of the car body traction seat assembly, and the securing plate 13 in sequence and then engages with a locking nut 19. The system securely connects the tethering ring body 10 to the car body traction seat assembly, and positions the hook-shaped part 11 on the outside of the car body traction seat assembly. This allows the tethering ring connected to the car body traction seat assembly to connect the subway car to the subway car during transportation, preventing displacement of the subway car and preventing deformation of the subway car shell or scratches on the paint.

[0031] See Figures 1-3 The fastening ring body 10 is U-shaped, and the fastening plate 13 is inclinedly disposed in the middle of the fastening ring body 10. The inclination direction of the fastening plate 13 is the same as the inclination direction of the inclined plate of the vehicle body towing seat assembly. A closed hanging ring is formed between the hook-shaped part 11 and the fastening plate 13. By setting the fastening plate 13 on the U-shaped fastening ring body 10 and forming a closed hanging ring between the fastening plate 13 and the hook-shaped part 11, the strength and rigidity of the hanging ring are ensured. The bending radius of the hook-shaped part 11 is R30.

[0032] See Figures 1-3 It also includes several first gaskets 14, which are located between the flat plate of the vehicle body towing seat assembly and the pad 17. A protective rubber is provided on the side of the first gasket 14 that contacts the vehicle body towing seat assembly. By providing the first gaskets 14 between the flat plate of the vehicle body towing seat assembly and the pad 17, the protective rubber fills the gap through its own deformation, ensuring no loose connection between the towing seat flat plate and the pad 17, and avoiding uneven bolt stress due to gaps during fastening (such as some bolts not being tightened or some bolts being overloaded).

[0033] See Figures 1-3 The protective rubber has several anti-slip protrusions evenly distributed on it. By setting the anti-slip protrusions, the physical structure is made more resistant, thereby improving the frictional stability between the protective rubber and the traction seat plate.

[0034] In some embodiments, the device further includes two reinforcing ribs 12, which are respectively disposed between the hook-shaped portion 11 and the fastening plate 13 and located on both sides of the hanging ring. By providing two reinforcing ribs 12 between the hook-shaped portion 11 and the fastening plate 13, the strength and rigidity of the fastening ring body 10 are improved.

[0035] See Figures 1-3 The fastening ring body 10 also includes two support portions 15, which are located at the lower end of the corresponding threaded portion 16 and at the upper end of the fastening plate 13, respectively.

By providing the support portions 15, the strength and rigidity of the fastening ring body 10 are further improved, and the firmness of the connection to the vehicle body towing seat assembly is enhanced.

[0036] See Figures 1-3 The system also includes several second gaskets 18, each with a gradually thinning thickness from one end to the other. Each second gasket 18 has a through hole for the two support portions 15 to pass through. Several second gaskets 18 are overlapped between the fastening plate 13 and the inclined plate of the vehicle body towing seat assembly. By gradually thinning the second gaskets 18 from one end to the other, the fastening ring body 10 can be connected to the inclined plates of the vehicle body towing seat assembly at different inclines, thereby improving the versatility of the fastening ring body 10 and ensuring the secure connection of the fastening ring body 10 to the vehicle body towing seat assembly.

[0037] See Figures 1-3 The second pad 18 is made of rubber, and the thickness and tilt angle of each second pad 18 may be different. Several anti-slip protrusions are evenly distributed on the side of the second pad 18 that contacts the inclined plate of the vehicle body traction seat assembly. By setting several anti-slip protrusions on the second pad 18, the frictional stability between the protective rubber and the inclined plate of the traction seat is improved.

[0038] See Figures 1-3 The fastening plate 13 is provided with protective rubber on both the side facing the hook-shaped part 11 and the outer side of the hook-shaped part 11, and several anti-slip protrusions are evenly distributed on the protective rubber. By providing protective rubber on both the side facing the hook-shaped part 11 and the outer side of the hook-shaped part 11 of the fastening plate 13, the friction between the subway vehicle and the fastening ring body 10 is increased, preventing the subway vehicle from shifting during transportation.

[0039] See Figures 1-3 The surfaces of the fastening plate 13, hook-shaped part 11, pad plate 17, and support part 15 are all coated with anti-rust paint. This anti-rust paint prevents the fastening device from rusting, ensuring its strength and rigidity. The pad plate is made entirely of 5mm thick steel plate.

[0040] Specifically, the device in this utility model is made of steel plate and steel bar, and the material is Q345B or better. The fastening device is installed on the vehicle body towing seat assembly. A single device can withstand a pulling force of 7t, and eight devices working together can withstand a maximum load of 56t without deformation.

[0041] See Figures 1-3 The fastening device in this utility model also includes a spring washer and a flat washer, wherein the spring washer is made of 64Mn. The length of the fastening ring body is 160mm, which is 200mm shorter than the length of the car body's tow seat, allowing it to be used even when there are components such as water seals, junction boxes, and cable outlets on both sides of the tow seat. The fastening ring body is integrally bent, and an M16 thread is machined on the top after bending for fastening, ensuring strength during use.

[0042] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
