The invention relates to the technical field of door body structures, in particular to a coal mine railway transportation compartment door which comprises an outer door and two guide rails located on the upper side and the lower side of the outer door, the guide rails are transversely installed on a compartment, and the outer door is used for blocking an opening area on the compartment from the outer side; a sliding table is arranged on the guide rail in a sliding mode, a plurality of parallel guide rods are rotationally arranged on the sliding table, the guide rods on the sliding table are rotationally connected with the outer door, and an inner door is fixed to the outer door. By adopting the outer door, the auxiliary door and the inner door, the inner side and the outer side of the opening area on the carriage can be blocked, the pressure of coal on the doors is effectively dispersed, acting force can be conveniently and directly transmitted to the inner wall of the carriage, and the dangerous situation possibly caused when a traditional plug pin and plug bush structure bears huge extrusion force is avoided; and potential injury to workers is reduced.
本发明涉及门体结构的技术领域,特别是涉及一种煤矿铁路运输用车厢门,包括外门和位于外门上下两侧的两个导轨,所述导轨横向安装在车厢上,所述外门用于对车厢上的开口区域从外侧进行封堵;所述导轨上滑动设有滑台,滑台上转动设有多个相互平行的导向杆,并且滑台上的导向杆均与外门转动连接,所述外门上固定有内门;通过采用外门、副门和内门,能够实现对车厢上开口区域的内外两侧的封堵工作,有效分散了煤炭对门的压力,方便将作用力直接传递至车厢内壁上,避免了传统插栓与插套结构在承受巨大挤压力时可能导致的危险情况,减少了对工人的潜在伤害。
