The invention discloses a winding type elevator with a cable breakage protection device. The elevator comprises a base, guide rails, a lifting platform and a power unit. The guide rails are provided with stop blocks. The lifting platform is arranged between the guide rails, a guide assembly is arranged on the lifting platform, and a cable breakage triggering mechanism is arranged on the lifting platform. The power unit is a winch, the power unit is arranged above the lifting platform, the power unit comprises a first power unit and a second power unit, and the first power unit and the second power unit are connected with the two opposite ends of the lifting platform through bearing steel wire ropes correspondingly, so that the lifting platform is suspended in a balanced mode. The first power unit and the second power unit operate synchronously to drive the lifting platform to ascend and descend vertically. The elevator is simple in structure, low in cost and high in space utilization rate. The two power units suspend the lifting platform in a balanced mode, no requirement for stress of a building hoistway exists, and the construction is convenient. The elevator runs smoothly, vibration and noise are low, the two power units are each provided with a band-type brake structure, the cable breakage protection device is further arranged, and the safety is high.
Description
technical field [0001] The invention relates to the field of vertical lifting elevators, in particular to a hoisting elevator with a cable break protection device. Background technique [0002] Vertical elevators are very mature and widely used civilian products with a history of hundreds of years. From the point of view of the installation site, vertical elevators are generally installed in commercial plazas, high-rise buildings and some villas. Among them, most of the vertical elevators installed in villas belong to home elevators. Compared with public elevators installed in commercial plazas or high-rise buildings, home elevators have the following characteristics and requirements: [0003] · Few landings, low lifting height; [0004] Low speed increase, generally lower than 0.4m / s; [0005] Small installation area, high requirements for area utilization; [0006] ·The pit depth and top buffer height are required to be as small as possible; [0007] Easy rescue in ca...
