The invention discloses a construction elevator driven by double motors, and relates to the technical field of elevators, the construction elevator driven by the double motors comprises a chassis, a standard knot and a lift car in sliding connection, a driving mechanism is installed between the lift car and the standard knot, and a double-shaft driving mechanism and an anti-falling mechanism are arranged between the lift car and the standard knot; the anti-falling mechanism comprises a positioning box fixed with the lift car; the driving shaft penetrates through the positioning box; the transmission block can be switched between a coaxial state and an eccentric state; a brake ring is arranged in the positioning box; when the rotating speed of the driving shaft exceeds a threshold value, friction braking is generated between the transmission block and the brake ring; in the falling process of the lift car, the falling speed of the lift car can be slowed down and locked.
本发明公开了一种双电机驱动的施工电梯,涉及电梯技术领域,包括双电机驱动的施工电梯,包括底盘、标准节及滑动连接的轿厢,所述轿厢和标准节之间安装有驱动机构,所述轿厢与标准节间设有双轴驱动机构及防坠机构,所述防坠机构包括:与所述轿厢固定的定位盒;贯穿所述定位盒的驱动轴及可切换同轴或偏心状态的传动块;所述定位盒内设置有制动环当所述驱动轴转速超阈值时,所述传动块与制动环产生摩擦制动;本发明在轿厢坠落过程中能够对其坠落速度减缓和锁止。
