The invention relates to a downward turning door structure facilitating the loading and unloading of a heavy fire-fighting robot, which comprises a hinge joint arranged at the tail of a carriage of a fire-fighting truck, a downward turning door hinged on the hinge joint, a connecting seat arranged at the bottom of the carriage on the inner side of the hinge joint, and a hydraulic cylinder hinged on the connecting seat, and a free end of a piston rod of the hydraulic cylinder connected with the downward turning door. A long vertical rod and a short vertical rod are arranged on the lower surface of the downward turning door at intervals, a connecting rod is arranged between the long vertical rod and the short vertical rod, the long vertical rod, the short vertical rod and the connecting rod are matched to form a parallel double-crank structure, and a driving rod is hinged to the side face, facing the hydraulic cylinder, of the long vertical rod. Due to the parallel double-crank structure and the cooperation setting of the hydraulic cylinder and the downward turning door, the long vertical rod and the short vertical rod rotate along with turning of the downward turning door, when the downward turning door is unfolded, a supporting point is provided for the middle of the downward turning door, the downward turning door is prevented from being fractured in the boarding and alighting process of the fire-fighting robot, and the whole device has linkage performance, is suitable for industrial production and has high practicability.

    本发明涉及一种便于重型消防机器人上下车的下翻门结构,该装置包括有设置在消防车车厢尾部的铰接头,铰接头上铰接有下翻门,位于铰接头内侧的车厢底部设置有连接座,连接座上铰接有液压缸,液压缸的活塞杆自由端与下翻门连接,下翻门下表面上间隔设置有长竖杆与短竖杆,位于长竖杆与短竖杆之间设置连杆,长竖杆、短竖杆以及连杆配合形成平行双曲柄结构,朝向液压缸的长竖杆侧面铰接有驱动杆,由于平行双曲柄结构,液压缸以及下翻门的配合设置,使得长竖杆与短竖杆随着下翻门的翻转而转动,在下翻门展开时,给下翻门中部提供了支撑点,防止在消防机器人上下车过程中将下翻门压裂,整个装置具有联动性,适用于工业生产中,具有很强的实用性。
