Description

Technical Field

[0001] The utility model relates to the technical field of vehicle frame structures, and specifically but not limited to, relates to a spliced ​​quick-change vehicle frame of an all-terrain transport vehicle. Background Art

[0002] An all-terrain transport vehicle is a light vehicle designed for non-highway travel and can be used on non-roads. It has wide tires and unique tread patterns to increase the ground contact area, generate greater friction and reduce ground pressure, allowing it to easily traverse harsh terrains such as beaches, riverbeds, forest roads, streams, etc., while carrying people or transporting goods.

[0003] All-terrain vehicles can be divided into wheeled and tracked types. Wheeled all-terrain vehicles mostly use an articulated structure to increase wheel travel, evenly distribute ground pressure and reduce the maximum peak value, thereby improving passability. They are light, flexible, fast, comfortable, and low-noise. In addition, their powertrain layout and control devices are basically the same as those of ordinary cars, making them easy to operate. Compared with wheeled transporters, tracked all-terrain transporters have a larger ground contact area and lower ground contact pressure, and can better complete tasks such as climbing slopes, crossing trenches and obstacles.

[0004] As the base of the whole vehicle, the frame must have sufficient strength and rigidity to bear the load of the vehicle and the impact from the tires. Due to the work requirements, the frame of the all-terrain transport vehicle should not only meet the strength and rigidity requirements, but also be designed to be relatively long and wide to ensure its normal operation in the underground tunnel. At present, the frame of the all-terrain transport vehicle is mostly designed as a whole, which is simple to design and manufacture. However, since it is a whole, it cannot be disassembled, which makes it relatively difficult to install parts and components, and it is not easy to replace them when a failure occurs. In addition, the non-detachable frame also means that the parts assembled with it are basically non-changeable.

[0005] In view of this, it is necessary to provide a new structure to solve at least part of the above problems. Utility Model Content

[0006] In response to one or more problems in the prior art, the utility model proposes a spliced ​​quick-change frame for an all-terrain transport vehicle, which divides the frame into three detachable parts. The parts of each part are assembled before assembly, which can effectively solve the problem of inconvenient parts assembly. It is also more convenient to replace parts when a failure occurs, which can greatly reduce the waste of time. At the same time, the structure of the entire vehicle can be changed by changing a part of the frame, thereby achieving performance optimization and function conversion of the entire vehicle.

The front frame and the intermediate frame, and the intermediate frame and the rear frame are connected by the trapezoidal gusset plate and the rectangular parallelepiped frame connector, specifically by bolt connection, to form a spliced ​​and detachable frame as a whole. The front frame longitudinal beam, front frame cross beam, front frame chassis; the middle frame longitudinal beam, middle frame cross beam, middle frame chassis; the rear frame longitudinal beam, rear frame cross beam, rear frame chassis are welded together to play a supporting role and ensure the stability of the frame. The front frame, middle frame, and rear frame have a relatively simple structural design while ensuring strength and rigidity, providing ample space for subsequent parts installation. The overall structure is a spliced ​​detachable structure to solve the problem of inconvenient parts assembly. It is also more convenient to replace parts when a fault occurs. At the same time, the structure of the entire vehicle can be changed by changing a part of the frame to achieve performance optimization and function conversion of the entire vehicle.

[0028] like Figure 1 As shown, a spliced ​​quick-change frame of an all-terrain transport vehicle includes a front frame 1, an intermediate frame 2, a rear frame 3, a trapezoidal gusset plate 4, a rectangular parallelepiped frame connector 5, and a triangular gusset plate 6. The front frame 1 includes a front frame longitudinal beam 1-1, a front frame cross beam 1-2, and a front frame chassis 1-3; the intermediate frame 2 includes an intermediate frame longitudinal beam 2-1, an intermediate frame cross beam 2-2, and an intermediate frame chassis 2-3; the rear frame 3 includes a rear frame longitudinal beam 3-1, a rear frame cross beam 3-2, and a rear frame chassis 3-3. The front frame 1, the intermediate frame 2, and the rear frame 3 are connected in sequence. Each frame part is composed of a longitudinal beam, a cross beam, and a chassis.

[0029] The frame connection is provided with a trapezoidal gusset plate 4 and a rectangular parallelepiped frame connector 5. The front frame 1 and the middle frame 2, the middle frame 2 and the rear frame 3 are connected by the trapezoidal gusset plate 4 and the rectangular parallelepiped frame connector 5, specifically by bolts, to form a spliced ​​and detachable frame as a whole.

[0030] The front frame longitudinal beam 1-1, the front frame cross beam 1-2, and the front frame chassis 1-3 are welded together, the middle frame longitudinal beam 2-1, the middle frame cross beam 2-2, and the middle frame chassis 2-3 are welded together, the rear frame longitudinal beam 3-1, the rear frame cross beam 3-2, and the rear frame chassis 3-3 are welded together, and at the same time, a triangular support plate 6 is welded at the connection between the frame cross beams, longitudinal beams, and chassis of each part to support them and ensure the stability of the frame.

[0032] The overall structure of the spliced ​​quick-change frame of the all-terrain transport vehicle is a spliced ​​detachable structure, which is used to solve the problem of inconvenient parts assembly. It is also more convenient to replace parts when a failure occurs. At the same time, the structure of the entire vehicle can be changed by changing a part of the frame, thereby realizing performance optimization and function conversion of the entire vehicle.

[0033] The specific assembly process of the spliced ​​quick-change frame of the all-terrain transport vehicle is as follows:

When assembling parts or replacing the frame due to a failure, unscrew the bolts at the frame connection and remove the trapezoidal gusset plate 4 and the rectangular frame connector 5. Because the frame is detachable, the structure of the entire vehicle can be changed by changing a part of the frame, and by changing the front and rear frames, it can be made possible to put down larger wheels. The middle frame is lengthened to increase the overall length of the vehicle, and the frame with a manipulator connection base, a drilling rig installation base, etc. is replaced to achieve the transformation of the function of the entire vehicle.
