The invention relates to the field of engineering machinery, in particular to an excavator cab door structure which comprises a door body hinged to a vehicle body, the door body comprises a main frame body located on the peripheral edge, a first vertical strip and a second vertical strip are arranged on the outer side of the main frame body, and the first vertical strip and the second vertical strip are arranged at intervals. An installation groove is formed between the first vertical strip and the second vertical strip, a sealing rubber strip is installed in the installation groove, a door frame corresponding to the door body is arranged on the vehicle body, and the sealing rubber strip abuts against the door frame in a pressing mode. The section of the frame profile is in a rectangular frame shape, and the first vertical strip and the second vertical strip are located on the side portion of the frame profile and on the side away from a vehicle body and extend in the direction of the door frame. The excavator cab door is high in structural strength and small in welding deformation, and the sealing performance of the cab door can be remarkably improved due to the fact that welding seams are located at the sectional material lap joint positions.

    本发明涉及工程机械领域,具体涉及一种挖掘机驾驶室门结构,其包括铰接在车体上的门本体,门本体包括位于四周边缘部位的主框体,主框体的外侧设有第一立条和第二立条,第一立条和第二立条相互间隔,第一立条和第二立条之间设有安装槽,安装槽中安装有密封胶条,车体上设有对应门本体的门框,密封胶条压靠在门框上。边框型材截面呈矩形框状,第一立条和第二立条位于边框型材的侧部且远离车体的一侧,第一立条和第二立条朝向门框的方向延伸。该挖掘机驾驶室门,结构强度高,焊接变形小,焊缝在型材搭接部位,能够显著提高驾驶室门的密封性。
