Description

Technical Field

[0001] This utility model belongs to the field of trailer technology, specifically to a large-tonnage transport trailer. Background Technology

[0002] In recent years, regulations have been established regarding the weight that different vehicles with different axle numbers and vehicle weights can carry in order to ensure driving safety. As a result, for different oversized and overweight goods, it is necessary to dispatch vehicles with corresponding carrying capacities for transportation, resulting in low vehicle applicability. Utility Model Content

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a large-tonnage transport trailer. This application provides the following technical solution:

[0004] The system includes a tractor, a frame, and wheel frames. The frame includes a gooseneck at the front end and a cargo platform at the middle end. The gooseneck is connected to the tractor. A connecting beam is provided at the rear end of the frame. A frame connecting part is provided at the front end of the wheel frames. The frame and the wheel frames are assembled and fixedly connected through the connecting beam and the frame connecting part. A wiring channel is provided at the bottom of the frame for arranging pipelines between the tractor and the wheel frames.

[0005] The connecting beam is provided with a first tenon and mortise, and the frame connecting part is provided with a second tenon and mortise that mates with the first tenon and mortise. The first tenon and mortise and the second tenon and mortise are provided with corresponding through holes in the transverse direction, and a connecting pin is provided in the through hole to connect and lock the first tenon and mortise and the second tenon and mortise.

[0006] The connecting beam is provided with a connecting beam through hole, and the frame connecting part is provided with a frame through hole corresponding to the position of the connecting beam through hole. The connecting beam through hole and the frame through hole are connected and fixed to the connecting beam and the frame connecting part by bolts or pins.

[0007] The connection between the connecting beam and the frame is achieved by assembling the first and second mortise and tenon and then passing through the connecting pin. At the same time, the connecting beam and the frame are also provided with corresponding connecting beam through holes and frame through holes, which are then connected and fixed by bolts or pins to ensure sufficient connection strength between the frame and the wheel frame.

[0008] The bottom of the connecting beam is provided with an inwardly inclined portion, and the first tenon is fixed to the inclined portion.

[0009] The wheel frame is provided with a pipe connector for connecting pipelines, and a clamping bracket is provided at the frame connection part. The clamping bracket is used to fix the pipe connector and corresponds to the position of the inclined part.

[0010] By setting an inclined section, the first tenon head is brought inward, making the connecting beam and the frame connection closer and the connection tighter. At the same time, it reduces the longitudinal shear stress on the welding point between the first tenon head and the connecting beam when the frame is loaded with cargo. Furthermore, after the wheel frame is spliced ​​with the frame, space is left for easy arrangement of connecting pipes.

[0011] The wiring channel is located in the middle of the bottom of the platform, and load-bearing beams are provided on both sides of the bottom of the platform. The two ends of the load-bearing beams are fixedly connected to the gooseneck and the connecting beam, respectively.

[0012] The wiring channel is provided with several reinforcing ribs at intervals. The two ends of the reinforcing ribs are fixedly connected to the load-bearing beam, and the top supports the platform. The reinforcing ribs are provided with wiring through holes for the pipes to pass through.

[0013] By setting up connecting beams to ensure the load-bearing strength of the platform, and arranging reinforcing ribs in the wiring channel, not only can the load-bearing strength of the platform be enhanced, but the wiring perforations set in the reinforcing ribs can also be used to store and protect the pipes.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] The chassis and wheel frame are detachably connected. When transporting different oversized goods, wheel frames with 3 / 4 / 5 or other axles can be assembled according to the conditions to transport goods, meet transportation requirements, and greatly improve vehicle utilization. At the same time, different chassis can be replaced to carry goods of different shapes or with specific fixing requirements (such as rolls), ensuring stability during cargo transportation and guaranteeing driving safety.
