The invention belongs to the technical field of earthwork, and particularly relates to a muck truck anti-rockfall carriage which comprises a muck carriage body; a supporting bottom plate is fixedly connected to the bottom face of the muck carriage body; a buffer pad is fixedly connected to the bottom face of the supporting bottom plate; two groups of symmetrical hydraulic rods are fixedly connected to the upper surface of the supporting bottom plate; symmetrical sliding sleeves are fixedly connected to each of the front face and the back face of the muck carriage body correspondingly; a sliding column is arranged above each hydraulic rod; and the top end of each sliding column penetrates through the corresponding sliding sleeve and extends to the position above the corresponding sliding sleeve. A hydraulic station is arranged to provide hydraulic support, a hydraulic rod drives the sliding column to slide in the corresponding sliding sleeve, the sliding column is matched with a hinge to drive a protective top plate to ascend, and after the protective top plate ascends to a certain degree, the protective top plate covers the top of the muck carriage body under the gravity action ofthe hinge and the protective top plate, so that the closed conveying of the carriage is realized, and the safety in transportation is improved.
本发明属于土方工程技术领域,尤其为一种渣土车防止落石的车厢,包括渣土车厢,所述渣土车厢的底面固定连接有支撑底板,所述支撑底板的底面固定连接有缓冲垫,所述支撑底板的上表面固定连接有两组相对称的液压杆,所述渣土车厢的正面和渣土车厢的背面均固定连接有相对称的滑动套,每个所述液压杆的上方均设有滑动柱,每个所述滑动柱的顶端均贯穿滑动套并延伸至滑动套的上方。本发明通过设置液压站提供液压支持,液压杆带动滑动柱在滑动套的内部进行滑动,滑动柱配合铰链能够带动防护顶板进行上升,当防护顶板上升一定程度后,利用铰链与防护顶板的重力作用,防护顶板将渣土车厢顶部遮盖,从而实现车厢的封闭输送,提高运输中的安全性。
