The invention relates to the technical field of tunnel construction protection, in particular to a crawler-type double-folding-arm drill jumbo which comprises a jumbo body, a cab, a crawler walking device, a supporting device and a mechanical arm. By arranging the scraper, the driving motor, the sliding block and other components, the sliding block moves through assistance of the driving motor, so that the scraper moves, on one hand, the scraper can clean water and impurities on the platform, on the other hand, the scraper and the arch-shaped frame are matched to remind workers, and therefore safety accidents are reduced; meanwhile, when large-area rockfall occurs, an electromagnet in a balancing weight is powered on, an extension plate moves upwards, a folding plate extends out under the assistance of an air cylinder, and therefore the extension plate, a protection plate and the folding plate form a herringbone structure, workers can hide below the herringbone structure and are prevented from being smashed by the rockfall, and the use safety of the equipment is improved.

    本发明涉及隧道施工防护的技术领域,特别是涉及一种履带式双折叠臂凿岩台车,其包括车体、驾驶室、履带行走装置、支撑装置和机械臂,所述机械臂上转动设置有操作台,所述操作台设置于机械臂的末端,通过设置刮板、驱动电机和滑块等部件,通过驱动电机的辅助使滑块进行移动,从而使刮板移动,一方面刮板可以将站台上的水和杂质进行清理,另一方面刮板和拱形架配合可以对工人进行提醒,从而减少安全事故的发生,同时在发生大面积落石时,通过配重块内的电磁铁通电,使延伸板向上移动,同时在气缸的辅助下使折叠板伸出,从而使延伸板、防护板和折叠板形成人字结构,工人可以躲在其下方避免被落石砸到,从而提高了设备使用的安全性。
