The invention provides an intelligent locking device for a sliding plug door of a cab, and relates to the field of sliding plug doors, the intelligent locking device comprises a door frame, the inner side end face of the door frame is concavely provided with a sinking groove with an L-shaped section, and the top end of the door frame is welded with a transverse supporting beam plate which is transversely arranged; a proximity sensor is locked and hoisted at the front side position of the middle section of the transverse supporting beam plate through a screw; two air cylinders are symmetrically and fixedly mounted on the left half section and the right half section of the front half part of the transverse supporting beam plate; two obliquely-arranged swing connecting rods and two L-shaped swing rods are symmetrically and rotationally mounted on the left half section and the right half section of the rear half part of the transverse supporting beam plate, and two sliding plug doors are rotationally mounted at the head ends of the two swing connecting rods and the head ends of the two L-shaped swing rods; compared with a traditional sliding plug door which only adopts an air cylinder type power device to conduct jacking and locking on the door body, the bottom of the door body is subjected to auxiliary inserting and fixing, the difficulty that the sliding plug door is violently disassembled is increased, and the locking safety performance of the two sliding plug doors can be improved.

    本发明提供用于司机室塞拉门的智能锁闭装置,涉及塞拉门领域,包括:门框,所述门框的内侧端面上内凹开设有一处L状截面沉槽,门框的顶端焊接有一处横向布置的横撑梁板,横撑梁板中间段的前侧位置通过螺丝锁紧吊装有一处接近传感器;所述横撑梁板前半部分的左右两半段上对称固定安装有两处气缸;所述横撑梁板后半部分的左右两半段上对称转动安装有两处倾斜布置的摆动连杆和两处L状摆杆,且两处摆动连杆和两处L状摆杆的首端转动安装有两处塞拉门,本发明相较于传统只单纯采用气缸类动力装置对门体实施顶压锁闭的塞拉门,本发明对门体的底部实施辅助插接固定增加了塞拉门被暴力拆卸的难度,有助于提升两处塞拉门的锁闭安全性能。
