The invention discloses a crane stall self-locking device based on the centrifugal force principle, and relates to the technical field of cranes. The crane stall self-locking device comprises a crane base, the upper surface of the crane base is fixedly provided with a hoisting motor, the upper surface of the crane base is fixedly provided with a supporting seat, and the outer wall of the supporting seat is rotatably connected with a rotating shaft; the outer wall of the rotating shaft is fixedly sleeved with a take-up wheel, a stall box is fixedly connected to the outer wall of the supporting seat, a limiting block is fixedly connected to the outer wall of the rotating shaft, the outer wall of the limiting block is fixedly sleeved with a sleeve, and a mounting frame is fixedly connected to the outer wall of the sleeve. According to the crane stall self-locking device based on the centrifugal force principle, through cooperation of centrifugal force and electromagnetic transmission, the stall self-locking device an play a role in protecting a hoisted object by locking hoisting equipment, meanwhile, a heavy object is prevented from hurting people, the effect of protecting people and the equipment is achieved, and compared with the prior art, the stall self-locking device is higher in reliability.

    本发明公开了一种基于离心力原理的起重机失速自锁装置,涉及起重机技术领域,包括起重机底座,所述起重机底座的上表面固定安装有起重电机,所述起重机底座的上表面固定安装有支撑座,所述支撑座的外壁转动连接有转轴,所述转轴的外壁固定套机有收线轮,所述支撑座的外壁固定连接有失速箱,所述转轴的外壁固定连接有限位块,所述限位块的外壁固定套接有套筒,所述套筒的外壁固定连接有安装架,本发明中,当物件快速下坠时,通过离心力和电磁传动配合使用,使该失速自锁装置能够通过锁紧吊重设备,对吊重的物件起到保护的作用,同时也避免重物砸伤人,对人们和设备均起到安全保护的作用,与现有技术相比,可靠性更高。
