Description

Technical Field

[0001] The utility model relates to the technical field of transport vehicles, in particular to an adjustment structure for a flatbed transport vehicle. Background Art

[0002] Flatbed trucks, also known as construction machinery trucks, flatbed trucks, and low-bed trucks, are mainly used to transport non-detachable objects such as excavators, loaders, harvesters, and cars. Flatbed trucks are characterized by a flat body, no fences or boxes, only a flatbed and a bracket, and they also transport some other goods. This type of vehicle is generally widely used in factories, construction sites and other large-scale production or engineering locations. The strong load-bearing capacity of flatbed trucks has played an important role in the process of economic development.

[0003] After searching, the patent announcement number is: CN207374217U "A flatbed transport vehicle", which includes a body, and a plurality of saddles are installed along the length direction of the body. The saddle includes a base installed on the body and two support plates. The ends of the two support plates close to each other are rotatably connected to the base. The two support plates are used to resist the support opening of the supporting rotating body. A driving member for pushing the support plate to rotate to change the size of the support opening is provided on the upper surface of the base. The utility model uses a new mechanical structure to support and transport objects through a saddle whose position can be adjusted along the length and width direction of the body and a support plate on the saddle with an adjustable support opening angle. It is suitable for the transportation of rotating engineering equipment, has a simple structure, and a wide range of applications.

[0004] However, the body flatbed of current flatbed transporters is a fixed structure, and the distance between the ladder structures is also fixed. When cars, broken-down cars, construction machinery or equipment of different widths want to be loaded onto the flatbed transporter, the width of the body flatbed cannot be adjusted. At the same time, when vehicles and equipment need to be loaded or unloaded from the flatbed transporter through the ladder, the ladder cannot adjust the spacing, making it difficult to load or unload cars, broken-down cars, construction machinery or equipment onto the flatbed transporter. At the same time, after loading onto the flatbed, the width of the flatbed is insufficient, which easily leads to the problem of unstable loading of goods. Utility Model Content
