The invention discloses a novel horizontal-pushing self-dumping semitrailer which comprises a frame, a carriage arranged on the frame, a movable pushing plate arranged in the carriage, a slide way, a movable frame, a main oil cylinder and an auxiliary oil cylinder, the slide way, the movable frame, the main oil cylinder and the auxiliary oil cylinder are arranged on the front portion of the frame, the slide way is fixedly welded to the front end of the frame, the movable frame is arranged in the slide way in a sliding mode, and one end of the main oil cylinder is hinged to the movable pushing plate. One end of the auxiliary oil cylinder is hinged to the frame, and the other end of the auxiliary oil cylinder is hinged to the movable frame. During use, when the movable push plate moves to the front end of a carriage, the main oil cylinder is in a complete contraction state, and the auxiliary oil cylinder is in a complete stretching state; when the movable push plate moves to the rear end of the carriage, the main oil cylinder is in a complete extension state, and the auxiliary oil cylinder is in a contraction completion state; during unloading, the main oil cylinder and the auxiliary oil cylinder relay for unloading, and the sum of material receiving and unloading strokes of the main oil cylinder and the auxiliary oil cylinder is equal to the length of the carriage. The invention has the advantages that: during unloading, the gravity center of the vehicle is low, and the turnover risk is low; the self-weight is light, the manufacturing cost is low and the difficulty is small; the loading capacity is high.
本发明公开了一种新型平推自卸半挂车,包含车架、设置在车架上的车厢、设置在车厢内的活动推板以及设置在车架前部的滑道、活动架、主油缸及辅助油缸,滑道焊固在车架前端,活动架滑设在滑道内,主油缸一端铰接在活动推板上,另一端铰接在活动架上,辅助油缸一端铰接在车架上,另一端铰接在活动架上。使用时,当活动推板移动到车厢前端时,主油缸处于完全收缩状态,辅助油缸处于完成伸出状态;当活动推板移动到车厢后端时,主油缸处于完全伸出状态,辅助油缸处于完成收缩状态;卸料时,主、辅油缸接力卸料,且主、辅油缸接料卸料的行程之和等于车厢长度。本发明优点是:卸料时,车辆重心低,翻车风险小;自重轻,制作成本低、难度小;装载能力强。
