When the connection between the container and the vehicle body is accidentally separated, the locking pieces can support the container to prevent accidents caused by the container falling, thereby improving the safety of the container when it is transported by air.

[0066] It should be noted that in the embodiment of the present invention, the connection components along the same direction refer to the length direction of the vehicle body, and the connection components and the cross beams are arranged in a one-to-one correspondence, and the mounting frame is the cross beam.

[0067] Figure 4 for Figure 3 Schematic diagram of the structure of the connected components in Figure 3 and Figure 4Each connecting assembly of the embodiment of the present invention includes a first sleeve 18 and a second sleeve 5, one end of the first sleeve 18 is rotatably connected to the end of the base frame, one end of the second sleeve 5 is telescopically connected to the other end of the first sleeve 18, and a locking member 17 is arranged on the other end of the second sleeve 5. In this way, the length of the connecting assembly formed by the assembly of the first sleeve 18 and the second sleeve 5 can be controlled to adapt to the transportation of containers of different heights.

[0068] Combination Figure 3 and Figure 4 Each connecting assembly of the embodiment of the present invention includes a first telescopic mechanism 6, and one end of the second sleeve 5 is telescopically connected to the other end of the first sleeve 18 through the first telescopic mechanism 6. In this way, through the control of the first telescopic mechanism 6, the second sleeve 5 can be telescoped relative to the first sleeve 18, thereby realizing the adjustment of the length of the connecting assembly formed by the assembly of the two.

[0069] Combination Figure 3 and Figure 4 In the embodiment of the present invention, one end of the second sleeve 5 is movably mounted in the first sleeve 18, and the first telescopic mechanism 6 is preferably a ball screw pair, which includes a motor 6.1, a screw rod 6.2 and a movable nut 6.3, wherein the motor 6.1 is fixedly arranged in the first sleeve 18, one end of the screw rod 6.2 is transmission-connected to the output end of the motor 6.1, the other end of the screw rod 6.1 extends out of the first sleeve 18, the other end of the screw rod 6.2 is located in the second sleeve 5, the movable nut 6.3 is fixedly connected to the other end of the screw rod 6.2, and the movable nut 6.3 is fixedly connected to one end of the second sleeve 5. In this way, the rotation of the motor 6.1 drives the screw rod 6.1 to rotate accordingly, driving the movable nut 6.3 to move axially along the screw rod 6.2, thereby driving the second sleeve 5 to telescope relative to the first sleeve 18, thereby achieving the purpose of adjusting the length of the connecting assembly formed by the assembly of the two.

[0070] Combination Figure 3 and Figure 4 In the embodiment of the present invention, the first support 7 and the second support 8 are fixedly disposed in the first sleeve 18 , and the first support 7 and the second support 8 are sequentially disposed along the direction from the first sleeve 18 to the second sleeve 5 .

[0071] The first support 7 and the second support 8 of the embodiment of the present invention can be integrally formed in the first sleeve 18 to facilitate processing and manufacturing and ensure the strength of the connection.

[0073] Furthermore, in order to improve the transmission effect of the screw rod 6.2 and the motor 6.1, the Figure 2 and Figure 3 A bearing 6.5 can be arranged on the second support 8 of the embodiment of the present invention, and one end of the screw rod 6.2 is arranged in the bearing 6.5. The arrangement of the bearing 6.5 can improve the stability of the screw rod 6.2 during rotation and reduce the shaking of the screw rod 6.2 during rotation, thereby achieving the purpose of improving the transmission effect.

[0074] Furthermore, combined with Figure 3 and Figure 4 In the embodiment of the present invention, a support member 9 is fixedly arranged in the first sleeve between the first support 7 and the second support 8. The support member 9 and the second support 8 are respectively arranged on both sides of the axial direction of the bearing 6.5. The bearing 6.5 is fixedly arranged on the second support 8. The support member 8 is fixed on the bearing 6.5. The support member 8 and the bearing 6.5 rotate synchronously. One end of the screw rod 6.3 moves through the support member 9 and the bearing 6.5 in sequence. In this way, when the screw rod 6.2 rotates, the support member 9 and the bearing 6.5 rotate synchronously. When the screw rod 6.2 stops rotating, the support member 9 and the bearing can improve the bearing capacity of the screw rod 6.2.

The first rotating shaft 15 and the second rotating shaft 16 are arranged close to the second sleeve 5 in sequence, so that the first sleeve 18 can be driven to flip by the extension and contraction of the first telescopic mechanism 10, thereby achieving the purpose of opening and closing the other ends of the two second sleeves 5 of a set of connecting assemblies.

[0079] In the embodiment of the present invention, the second telescopic mechanism 10 can be a linear motion mechanism such as an electric push rod, a drive motor, etc., and the embodiment of the present invention does not limit this.

[0080] Combination Figure 3 and Figure 4The other end of the second sleeve 5 of the embodiment of the present invention is bent toward the mounting frame to form a bent portion 11.

A groove is arranged at the bottom of the container 4 corresponding to the locking member 17. Since the second rod 17.2 is cone-shaped, it can be quickly inserted into the groove to improve the gripping effect on the container.

[0082] It should be noted that the locking member 17 of the embodiment of the present invention can be directly arranged on the side wall of the other end of the second sleeve 5, and the groove corresponding to the locking member 5 is arranged on the side of the container 4, which can also achieve the purpose of preventing the container from falling.

[0083] In addition, since the embodiment of the present invention is provided with at least two groups of connection components, different numbers of connection components can be selected for assembly with the container according to the length of the container, which has the characteristic of strong applicability.

[0092] Embodiment 4:

[0093] Since the main load-bearing beam of the car body in the embodiment of the present invention is a single beam, that is, the bogie structure will be more compact, how to arrange the braking mechanism of the bogie is a technical problem that needs to be solved urgently. The technical solution shown in the fourth embodiment solves this problem.

[0094] Figure 6 for Figure 1 The structural diagram of the bogie. Figure 7 for Figure 6 Schematic diagram of the brake mechanism in Figure 1 , Figure 6 and Figure 7 The bogie 2 includes a frame 2.1, a running wheel set, a drive motor 2.3, a gear box 2.4 and a brake mechanism, and the running wheel set, the drive motor 2.3 and the brake mechanism are arranged one by one, wherein:

[0095] There are two running wheel assemblies, which are arranged opposite to each other along the length direction of the frame 2.1. Each running wheel assembly includes two running wheels 2.5. The two running wheels 2.5 in each running wheel assembly are rotatably arranged on both sides of the width direction of the frame 2.1.

[0096] There are two drive motors 2.3, which are respectively arranged at both ends of the frame 2.1 in the length direction, and the output shaft of each drive motor 2.3 is arranged along the length direction of the frame 2.1;

[0097] Two gear boxes 2.4 are provided, and both gear boxes 2.4 are fixedly arranged on the frame 2.1. Each gear box 2.4 is arranged between the corresponding driving motor 2.3 and the walking wheel set. Each gear box 2.4 has an input shaft and two output shafts. The input shaft of each gear box 2.4 is arranged along the length direction of the frame 2.1. The input shaft of each gear box 2.4 is drivingly connected to the output shaft of the corresponding driving motor 2.3. The two output shafts of each gear box 2.4 are respectively drivingly connected to the rotating shafts of the two walking wheels 2.5 of the corresponding walking wheel set.

[0098] There are two brake mechanisms, and the brake part of each brake mechanism is arranged between the output shaft of the corresponding drive motor 2.3 and the input shaft of the gear box 2.4.

[0099] When the bogie moves, the output shaft of the driving motor 2.3 outputs power, which is transmitted to the two running wheels 2.5 of the corresponding running wheel group through the two output shafts of the corresponding gear box 2.4 to rotate. The running wheels 2.5 can move on the running track, thereby driving the bogie, the car body and the container to move, thereby achieving the purpose of container transshipment. When the bogie needs to stop, the braking part of the braking mechanism is driven to cut off the rotation of the output shaft of the driving motor 2.3 and the input shaft of the gear box 2.4, and the running wheels 2.5 stop rotating, thereby stopping the bogie, the car body and the container.

[0100] In the bogie in the embodiment of the present invention, since the braking part of the braking mechanism is arranged between the output shaft of the corresponding drive motor and the input shaft of the gear box, the space of the compact bogie can be reasonably utilized to achieve the purpose of bogie braking.

[0102] Combination Figure 7 Each brake mechanism of the embodiment of the present invention comprises a brake disc 2.6 and a brake caliper 2.7. The brake disc 2.6 is arranged on the input shaft of the gear box 2.4, and the brake caliper 2.7 is arranged on the frame 2.1. The brake disc 2.6 realizes braking through the brake caliper 2.7.

When rapid braking is required, the electronic control unit 2.9 and the hydraulic control unit 2.10 are started simultaneously to achieve the purpose of rapid braking of the brake disc 2.6.

[0104] Combination Figure 6The bogie of the embodiment of the present invention further includes two guide wheels 2.2, which are arranged corresponding to the running wheels 2.5. The guide wheels 2.2 are arranged on the outer sides of the corresponding running wheels 2.5 along the length direction of the frame 2.1. The guide wheels 2.2 are rotatably arranged on the frame 2.1. The rotation plane of the guide wheels 2.2 is perpendicular to the rotation plane of the running wheels 2.5. The guide wheels 2.2 are used to contact with the guide rails where the running tracks are located to limit the moving direction of the running wheels 2.5.

[0105] It should be noted that the guide wheel 2.2 of the embodiment of the present invention needs to protrude from the running wheel 2.5 to prevent interference with the movement of the running wheel 2.5.
