[0045] The utility model discloses a tractor trailer suitable for multiple terrains. The heavy objects are hoisted onto the heavy object placement platform, and the mobile trolley is connected to the platform through the traction rod assembly 13. Then the mobile trolley drags the tractor trailer to move. Because the front wheel assembly 11 is rotatably installed on the vehicle base 10, when encountering a bend, the front wheel assembly 11 reduces the turning radius of the tractor trailer after reasonable rotation, so that the tractor trailer can flexibly pass through sections with more bends. The utility model provides a tractor trailer suitable for multiple terrains. The front wheel assembly 11 can rotate freely to reduce its turning radius, so that it can flexibly pass through sections with more bends, and can be flexibly spliced ​​to meet the transportation needs of heavy objects of different lengths. The traction rod assembly 13 is detachably installed on the rear end of the front wheel assembly 11 and / or the vehicle base 10 in the direction of travel, so as to facilitate the multi-directional dragging of the tractor trailer.

[0046] In one embodiment, the vehicle base 10 is formed by welding square tubes spliced ​​vertically and horizontally.

[0047] The beneficial effects of the above technical solution are:

[0048] The vehicle base 10 is formed by welding square tubes spliced ​​vertically and horizontally, thereby improving the connection strength of the vehicle base 10 .

[0049] In one embodiment, four L-shaped guard plates 14 are arranged in an array at the top of the vehicle base 10 near the corners.

[0050] The beneficial effects of the above technical solution are:

[0051] The arrangement of the four L-shaped guard plates 14 facilitates the stable placement and fixation of the heavy objects on the heavy object placement platform.

[0052] In one embodiment, the traction rod assembly 13 is an isosceles acute triangle structure, which is welded from multiple square tubes or No. 10 channel steels. A traction rod 14 is installed at one end of the traction rod assembly 13, and a connecting pin assembly 15 that is detachably connected to the front wheel assembly 11 and / or the vehicle base 10 is installed at the other end of the traction rod assembly 13.

[0053] The working principle and beneficial effects of the above technical solution are:

[0054] The towing rod 14 is detachably connected to the front and rear ends of the towing trailer in the traveling direction through the connecting pin assembly 15, so as to facilitate the towing trailer to achieve multi-directional towing. In the case where the towing rod 14 is not installed, multiple towing trailers can also be flexibly spliced ​​using the connecting pin assembly 15 to meet the transportation needs of heavy objects of different lengths.

[0055] In one embodiment, the front wheel assembly 11 comprises:

[0056] A rotating frame 16, one side of which is reserved with a mounting wing plate for detachably connecting the traction rod assembly 13, and a front solid tire set 17 is symmetrically mounted on the rotating frame 16;

[0057] A center bearing 18, the center bearing 18 is mounted on the rotating frame 16 through a bearing mounting assembly;

[0058] The central fixing tube is installed at the bottom end of the vehicle base 10 and close to the front end of the vehicle base 10 in the walking direction. The end of the central fixing tube away from the vehicle base 10 is installed on the inner ring of the central bearing 18.

[0059] The working principle and beneficial effects of the above technical solution are:

[0060] The center bearing 18 is installed on the rotating frame 16 through the bearing mounting assembly, and the center fixing cylinder connected to the vehicle base 10 is installed on the inner ring of the center bearing, so as to realize the rotation of the rotating frame 16 at the bottom end of the vehicle base 10, thereby realizing the multi-angle flexible rotation of the front wheel assembly 11, and the front solid tire group 17 is symmetrically installed on the rotating frame 16 to realize the movement of the rotating frame 16.

[0061] In one embodiment, the rear wheel assembly 12 includes:

[0062] A fixing frame 19, the fixing frame 19 is integrally welded to the bottom end of the vehicle base 10 and is close to the rear end of the vehicle base 10 in the walking direction;

[0063] The rear solid tire group 20 is symmetrically mounted on the fixing frame 19 .

[0064] The working principle and beneficial effects of the above technical solution are:

[0065] The front wheel assembly 11 is equipped with a front solid tire set 17, and the rear wheel assembly 12 is equipped with a rear solid tire set 20, so as to achieve a heavy load-bearing capacity of the towing trailer. The theoretical load-bearing capacity is above 20 tons.

[0066] like Figure 3 , Figure 4 As shown, in one embodiment, the bearing mounting assembly:

[0067] A fixed block 21, the fixed block 21 is fixedly mounted on the top of the rotating frame 16;

[0068] The movable block 22 is slidably mounted on the rotating frame 16. The movable block 22 and the fixed block 21 are both provided with arc surfaces at one end close to each other, so that when the movable block 22 and the fixed block 21 are spliced, the outer ring of the center bearing 18 can be completely limited;

[0069] A side mounting groove 23, which is disposed at an end of the movable block 22 away from the fixed block 21;

[0070] A guide groove 24, which is formed at the top of the movable block 22 and communicates with the side mounting groove 23;

[0071] The flip rod 25 has one end connected to the top of the rotating frame 16 through the central shaft 26 , and the other end of the flip rod 25 extends into the side mounting groove 23 and is provided with a guide rod 27 slidably connected to the guide groove 24 .

[0072] A limiting slide rail 28 is installed at the top of the rotating frame 16 to facilitate the sliding of the bottom end of the movable block 22 .

[0073] Among them, a U-shaped block 29 is symmetrically installed on the top of the rotating frame 16 with the sliding direction of the movable block 22 as the center, and both ends of the positioning screw 30 are installed on the U-shaped block 29. A through hole is opened at the end of the flip rod 25 near the central axis 26 to facilitate the positioning screw 30 to pass through.

[0074] The middle section of the positioning screw 30 is a smooth portion, and the diameter of the perforation is equal to the diameter of the positioning screw 30 .

[0075] The working principle and beneficial effects of the above technical solution are:

[0076] The fixed block 21 is connected to the rotating frame 16 by a fixing nut. After the center bearing 18 is placed against the arc surface of the fixed block 21, the guide rod 27 is manually pulled to make the guide rod 27 slide in the guide groove 24 toward the middle section of the guide groove 24. The guide rod 27 drives the flip rod 25 connected thereto to slide toward the middle section of the guide groove 24. During the rotation of the flip rod 25 around the center axis 26, the flip rod 25 presses against the movable block 22 and slides in the direction close to the fixed block 21. During the sliding of the movable block 22 along the limiting slide rail 28, the flip rod 25 gradually tends to be parallel to the limiting slide rail 28. When the flip rod 25 is parallel to the limiting slide rail 28, the movable block 22 and the fixed block 21 are spliced ​​together, thereby completely limiting the outer ring of the center bearing 18. Then, the positioning screw 30 is perforated, and the two ends of the positioning screw 30 are fixed to the U-shaped block 29 by nuts, thereby realizing the locking and fixing of the flip rod 25.

[0077] When it is necessary to disassemble the bearing installation assembly, loosen the nut, pull out the positioning screw 30 from the self-piercing hole, manually pull the guide rod 27, and the guide rod 27 slides in the guide groove 24 toward the middle section of the guide groove 24. The flip rod 25 pulls the movable block 22 to slide away from the fixed block 21, thereby releasing the fixing of the bearing installation assembly to the center bearing 18.

[0078] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
