The invention discloses a frame structure of the semitrailer; the frame structure comprises a gooseneck, a cargo carrying plate, a rear suspension plate and a traveling plate, the front end of the cargo carrying plate is detachably connected with the rear end of the gooseneck, the rear end of the cargo carrying plate is fixedly connected with the front end of the rear suspension plate, and the traveling plate is fixedly installed on the side portion of the cargo carrying plate. The traveling plate is fixedly connected with the front end of the rear suspension plate; the frame structure is characterized in that a through groove is formed in the traveling plate, and the through groove penetrates through the front end of the traveling plate through the rear suspension plate so that wheels of a loading vehicle can stably walk. Compared with the prior art, the frame structure has the advantages that the wheels of the vehicle can stably walk on the through groove; problems of shaking, tilting and the like are solved, the safety coefficient is higher, the crawler belt can walk on the through groove, the semitrailer has the loading and transporting capacity on the crawler belt type special vehicle, the overall loading range is effectively expanded, and the universality is high.
本发明公开了一种半挂车的车架结构,包括鹅颈、载货板、后悬板及行车板,所述载货板的前端与所述鹅颈的后端为可分离式连接,且其后端与所述后悬板的前端固定连接,所述行车板固定安装在所述载货板的侧部,且其与所述后悬板固定连接,其特征在于:所述行车板上具有通槽,所述通槽经由所述后悬板贯穿到所述行车板的前端,以供装载车辆的车轮平稳行走,本发明与现有技术相比的优点在于:车辆的车轮能够平稳的在通槽上行走,避免出现晃动、倾斜歪倒等问题,安全系数更高,且履带能够在通槽上行走,使得半挂车对履带式特种车辆具有装载运输能力,有效扩大了整体的装载范围,通用性强。
