The invention relates to the field of building hoisting equipment, and discloses a conical brake device of a building hoisting electric hoist. The device comprises a shell and a motor shaft of an electric hoist, one end of the motor shaft extends into the shell and is fixedly connected with a brake wheel, a brake ring is arranged in the middle of an inner cavity of the shell, a brake spring is arranged on the motor shaft, the brake ring is rotationally connected with the shell in a sleeving mode, and a clamping mechanism for limiting the brake ring is arranged on the outer side of the shell. Through the structural design that the brake ring for braking a brake wheel is linked to a positioning plate a rotating disc, a crank connecting rod mechanism, a linkage shaft, a piston sliding plate, an annular oil pipe, a clamping mechanism and an oil control device in a shell, on the premise that normal braking of the brake device is not affected, under the emergency conditions such as electrical faults or power failure of a power grid, the oil control device far away from the shell is manually controlled, and a heavy object suspended after braking in an emergency can be slowly released, so that the safety performance of the electric hoist after braking in a tight condition is improved.
本发明涉及建筑起吊设备领域,且公开了一种建筑起吊电葫芦锥形制动装置,包括壳体和电葫芦的电机轴,电机轴的一端延伸至壳体内并固定连接有制动轮,壳体内腔的中部设有制动环,电机轴上设有制动弹簧,所述制动环与壳体旋转套接,且壳体的外侧设有对制动环进行限位的卡位机构。通过壳体内对制动轮进行制动的制动环联动定位板、转盘、曲柄连杆机构、联动轴、活塞滑板、环形油管、卡位机构和控油装置的结构设计,在不影响制动装置正常制动的前提下,当发生电气故障或电网停电等紧急情况下,通过人工控制远离壳体的控油装置,可缓速释放紧急情况下制动后悬挂的重物,进而提高了电葫芦紧紧情况制动后的安全性能。
