The invention relates to the technical field of constructional engineering, and discloses a stall self-locking device used in constructional engineering and based on an electrorheological fluid principle. The inner side of a body is movably connected with a turntable, teeth are fixedly installed on the inner wall of the body, the bottom ends of the teeth are movably connected with a bayonet socket, and one end, far away from the bayonet socket, of the teeth is movably connected with a disc. According to the stall self-locking device used in constructional engineering and based on the electrorheological fluid principle, if a tower crane stalls and falls in the process of lowering building materials, current passes through the electrorheological fluid and the electrorheological fluid changesfrom liquid into solid, the electrorheological fluid is abutted against an inserting rod to be inserted into a groove between the teeth, so that the inserting rod cannot rotate, it is ensured that the tower crane does not continue to descend when transporting the building materials, the protection of people is improved, possible safety accidents caused by the tower crane are avoided, the safety of operators at a building construction site is greatly protected, the problem of construction progress delay caused by the safety accidents is avoided, and the national requirements for safety construction are met.

    本发明涉及建筑工程技术领域,且公开了一种基于电流变体原理的建筑用失速自锁装置,所述本体内侧活动连接有转盘,本体的内壁上固定安装有齿牙,齿牙底端活动连接有插接座,远离插接座的那一端活动连接有圆盘。该基于电流变体原理的建筑用失速自锁装置,通过假如塔吊在放下建材过程中发生失速下落的情况,电流变体内通过电流由液体变为固体,电流变体抵动插杆插接至齿牙之间的凹槽内,从而使其无法转动,保证了塔吊在运输建材的时候不在继续下降,从而提高了对人的保护,避免了由此可能引发的安全事故,极大的保护了建筑施工现成操作人员的安全,避免了因安全事故导致施工进度延误的问题,符合国家对安全施工的要求。
