Description

Technical Field

[0001] The invention relates to the technical field of engineering machinery, and in particular to a technology for improving the body structure of an amphibious double-section crawler vehicle. Background Art

[0002] The single-section crawler body consists of a crawler chassis and a body platform. The crawler chassis uses steel crawler shoes, which are wear-resistant and high-strength. The body platform is fixed to the crossbeam of the crawler chassis and is used to install and fix components such as the main engine, pump station and control console. Most of the crawler vehicle body structures in the prior art are single-section bodies, and even fewer have amphibious performance. Even if they have amphibious performance, most of the bodies are shallow wading and rarely have floating performance. Mainly, most of the single-section crawler vehicle bodies are formed by a combination of thickened armored steel plates and reinforcing ribs, and their shapes are mostly T-shaped structures. The body structure mainly adopts a wide and short geometric design, which greatly increases the weight of the body. The internal space is relatively very compact, and the walking space designed on the left and right sides of the body is relatively small, resulting in a small track contact area. Therefore, it is difficult for the single-section crawler vehicle body structure to adapt to some complex environments, such as swamps, rivers, lakes, snow, etc. It is even more difficult for the double-section crawler vehicle body to adopt this structure.
