[0027] Embodiment one

[0028] As shown in Figures 1-4 A trailer frame for heavy cargo transportation, comprising an air path system 1, a vehicle body frame 2, a disconnectable axle assembly 3, a gantry frame 4 and a hydraulic outrigger 5, the air path system 1 is installed at the front end of the vehicle body frame 2, the disconnectable axle assembly 3 and the gantry frame 4 are both welded on the vehicle body frame 2, and the hydraulic outrigger 5 is installed at the four corner fulcrums of the vehicle body frame 2 through bolts;

[0029] The working principle of the above technical solution is as follows: The front end of the vehicle frame 2 is connected to the transport vehicle. One end of the air circuit system 1 is connected to the transport vehicle, and the other end is connected to the vehicle frame 2. The air source of the air circuit system 1 comes from the transport vehicle. Before driving, the air suspension 307 is inflated. When the air circuit system 1 is disconnected from the front transport vehicle, the tire assembly 306 is locked, and the trailer frame can no longer move, preventing the trailer frame from moving arbitrarily during loading and unloading. The function of the disconnectable axle assembly 3 is to serve as the main load-bearing structure and shock absorption structure of the trailer frame during driving. It provides auxiliary support during loading and unloading operations, making the vehicle frame 2 more stable. The gantry frame 4 is welded to the main beam of the vehicle frame 2 and reinforced by the inclined beam. It mainly serves to guide the movement of other equipment. The function of the hydraulic outriggers 5 is to support the ground with the four hydraulic outriggers 5 during loading and unloading operations, maintaining the overall balance of the vehicle frame 2.

[0030] Example 2

[0031] like Figures 1-4 As shown, the air pipes in the air system 1 are connected to the bottom of the vehicle frame 2 by clips;

[0032] The vehicle frame 2 is generally U-shaped;

[0033] The working principle of the above technical solution is as follows: the air pipe in the air system 1 is connected to the bottom of the vehicle frame 2 by a buckle to prevent the air pipe in the air system 1 from being scratched.

[0034] Example 3

[0035] like Figures 1-4 As shown, the disconnectable axle assembly 3 includes an axle support beam 303, which is connected to the vehicle frame 2 via a rotating bearing assembly 301. A connecting support frame 302 is welded at the middle position of the axle support beam 303, and the bottom of the connecting support frame 302 is fastened to the suspension assembly 309 by bolts. The suspension assembly 309 is connected to the tire assembly 306 via a rotating shaft.

[0036] An air suspension 307 is welded between the axle support beam 303 and the suspension assembly 309, and a copper wire shock absorber 308 is welded between the axle support beam 303 and the suspension assembly 309.

[0037] The working principle of the above technical solution is as follows: the axle support beam 303 and the suspension assembly 309 are used to bear the impact load of the tire assembly 306 during driving, and the air suspension 307 and the copper wire shock absorber 308 are used to absorb the impact load of the trailer frame during driving, thus playing a shock absorption role.

[0038] Example 4

[0039] like Figures 1-4As shown, a wheel cover 304 is provided above the tire assembly 306, and the wheel cover 304 is fixed to the middle section of the axle support beam 303 by a wheel cover bracket;

[0040] The working principle of the above technical solution is as follows: the wheel cover 304 protects the tire assembly 306.

[0041] Example 5

[0042] like Figures 1-4 As shown, the end of the axle support beam 303 is provided with a rotary lock 305, which is fastened to the vehicle frame 2 by double nuts;

[0043] The working principle of the above technical solution is as follows: The axle support beam 303 and the suspension assembly 309 are used to bear the impact load of the tire assembly 306 during driving and to transfer the impact force to the main beam of the vehicle frame 2. The function of the rotary lock 305 is to lock the axle support beam 303 and the main beam of the vehicle frame 2 before the vehicle travels with the transport vehicle, thereby reducing the shaking of the disconnected axle assembly 3 during driving and increasing driving stability. The function of the air suspension 307 and the copper wire shock absorber 308 is to absorb the impact load of the trailer frame during driving and play a shock absorption role.

[0044] Example 7

[0045] like Figures 1-4 As shown, the rotating bearing assembly 301 includes an axle support 3011. One end of the axle support 3011 is fixedly connected to the vehicle frame 2, and the other end of the axle support 3011 is rotatably connected to the end of the axle support beam 303 through a rotating bearing 3012.

[0046] The axle support 3011 and the axle support beam 303 are provided with a wear-resistant pad 3013, and the rotating bearing 3012 is threadedly connected to the bearing end cap 3014.

[0047] The working principle of the above technical solution is as follows: After the axle support 3011 is connected and fixed to the trailer frame 2, the anti-wear pad 3013 is placed on the end bearing of the axle support beam 303. The axle support beam 303 is moved into the axle support 3011 so that the bearing hole of the axle support beam 303 is concentric with the hole of the axle support 3011. Then, the rotating bearing 3012 is inserted into the hole. After the rotating bearing 3012 is installed in place, the bearing end cap 3014 is fixed to the rotating bearing 3012 by threaded connection. A relatively closed cavity is formed between the axle support beam 303 and the rotating bearing 3012.

[0048] During loading and unloading operations, the axle support beam 303 and the axle support 3011 rotate, causing the tire assemblies 306 on both sides of the trailer frame 2 to extend outward, providing auxiliary support and making the trailer frame 2 more stable.

[0049] Embodiment Eight

[0050] As Figures 1-4 shown, the axle support beam 303 and the rotating bearing bush 3012 form a relatively closed chamber, the axle support beam 303 is provided with a grease nipple 3015 at the end, and the chamber is communicated with the outside through the grease nipple 3015;

[0051] The working principle of the above technical scheme is that the grease can be injected into the chamber through the grease nipple 3015 to increase the flexibility of rotation, wherein the axle support 3011 is a fixed support point, the rotating bearing bush 3012 makes the axle support beam 303 rotate, the anti-wear pad 3013 can adjust the installation gap between the axle support 3011 and the axle support beam 303, and can also cooperate with the grease to increase the smoothness of the axle support beam 303 in the rotating process, improve the anti-wear performance, and the function of the bearing bush end cover 3014 is to prevent the rotating bearing bush 3012 from jumping during driving and to seal the bearing chamber.
