The invention relates to the technical field of semitrailers, and discloses a high-safety semitrailer carriage which comprises a bottom plate, a steel coil mounting area and a protection area are arranged on the bottom plate, and the protection area is provided with a groove, a movable plate, a first hydraulic cylinder and a second hydraulic cylinder, and the first hydraulic cylinder and the second hydraulic cylinder are mounted in the groove. The steel coil protection device has the following advantages and effects that when a steel coil rolls backwards, leaves a steel coil mounting area and enters a protection area in an unexpected situation, the movable plate is overturned downwards under the acting force of the steel coil, the elastic force of the spring can play a role in first blocking, and the groove structure plays a role in second blocking; the buffer rubber columns on the inner walls of the grooves prevent the steel coils from moving backwards and rotating, the third blocking effect is achieved, the piston rods of the second hydraulic cylinders extend out and are aligned with the steel coils in the protection area, and the fourth blocking effect is achieved. The steel coil is effectively prevented from rolling out of the carriage to cause serious accidents, and the safety is improved.

    本发明涉及半挂车技术领域,公开了一种安全性高的半挂车车厢,包括底板,所述底板上设有钢卷安装区域、防护区域,所述防区区域设有凹槽、活动板、安装于所述凹槽内第一液压缸、第二液压缸。本发明具有以下优点和效果:在碰到突发意外情况钢卷向后滚动,离开钢卷安装区域并进入防护区域,活动板受到钢卷作用力后向下翻转,弹簧弹力形成能起到第一道阻挡作用,凹槽结构起到第二道阻挡作用,凹槽内壁的缓冲橡胶柱阻挡钢卷向后运动以及旋转,起到第三到阻挡作用,第二液压缸活塞杆伸出并对准防护区域的钢卷,起到第四道阻挡作用,因此,在发生意外情况致使钢卷向车厢后方滚动时,本发明有效阻挡钢卷滚出车厢造成严重事故,提高安全性。
