Description

multipurpose tractor trailer

technical field

The utility model relates to a transportation tool, in particular to a trailer with an improved structure.

Background technique

In some construction fields, after construction materials such as steel bars and pipes are transported to the construction site, when the materials are used in construction, the process of transporting them from the stacking place to the construction site is mostly done manually or by small transport vehicles. However, as soon as the transport vehicle leaves the factory, the dimensions of the carriage have been fixed and are not easy to change. For some building materials such as steel bars and pipes with long lengths, since the carriage is not much wider than the width of the tractor, these lengths are not much wider during transportation. Large materials can only be fixed in the trunk at one end, and the other end can only be dragged on the ground, which will generate dust and noise and damage the ground. What's more, when unloading the truck, the building materials are unloaded one by one, which is slow and laborious.

Contents of the invention

The technical problem to be solved by the utility model is: aiming at the above problems, a multipurpose traction trailer is provided.

The technical solution of the utility model is: it includes a car body and walking wheels, one end of the car body is provided with a traction part for connecting the traction vehicle, the other end is provided with a handlebar to be held by manpower, and a loading device is provided on both sides of the car body , the loading device is an "L"-shaped structure composed of a horizontal frame and a vertical frame, and the loading device is provided with hinged parts at its corners to connect with the edges on both sides of the vehicle body.

The technical effect of the utility model is that it has the advantages of reasonable structure and convenient use. Can be used as a trailer for small towing vehicles or as a human cart. There are special loading devices designed for long building materials such as steel bars and pipes on both sides. Putting long materials on both sides will not hinder traction and can achieve the purpose of fast unloading. Simultaneously, it can also be used to manually drag and adjust other trailer boxes by means of the traction unit and the handlebar.

Detailed ways

As shown in Figure 1, it includes a car body 1 and road wheels 2. One end of the car body 1 is provided with a traction part 3 for connecting a traction vehicle, and the other end is provided with a handlebar 4 held by manpower. There is a loading device 5 for loading longer length materials. The loading device 5 is an "L"-shaped structure composed of a horizontal frame 6 and a vertical frame 7. The two side edges are connected. The loading device 5 has two optional states when carrying materials. When loading shorter materials, the horizontal frame 6 is flat on the car body, which is no different from the common cart (locking device can be set on the car to lock its state). When loading longer materials, turn the loading device 5 to the outside of the car body 1, erect the horizontal frame 6 (the state can be locked by a rope or a specially made fixed pull bar), and place longer materials from both sides of the car on the horizontal On the vertical frame 7 of state, and fasten, because when pulling with vehicle at this moment, longer material is positioned at the both sides of car, can not hinder driving, and material also need not hold on the ground. When unloading the truck, the loading device 5 can be lifted directly to unload the material as a whole from both sides, which is very convenient and labor-saving.

The end of the traction part 3 is wedge-shaped. When using the traction part 3 to adjust a small trailer, the tip of the wedge can be inserted into the bottom of the traction frame of the trailer, and then the connecting holes of the two are aligned and inserted into the locking pin. At the same time, the utility model can easily lift the trailer and take it away with the help of the lever, thereby saving the process of lifting the trailer by a special person, and making the connection process more convenient and labor-saving.
