Abstract

The invention discloses a vertical ascending-and-descending elevator with a machine room. The vertical ascending-and-descending elevator comprises a lift car, a cable and a lift way, wherein the cableis arranged on the lift car, and the life way is matched with the lift car. The lift way is provided with slide rails. The lift car is provided with a safety device, wherein the safety device is usedfor preventing the lift car from falling after the cable is ruptured. According to the vertical ascending-and-descending elevator, by means of the safety device, after the cable is ruptured, the safety device can be started, and the lift car is prevented from falling; and thus, personal safety of passengers inside the lift car is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of elevator safety, in particular to a machine-room vertical elevator. Background technique [0002] Vertical elevators are widely used as construction equipment commonly used in people's daily life. In the actual use process, due to certain factors, the car will suddenly fall, such as acceleration, or abnormal conditions such as overspeed, which will cause serious damage to the personal safety of passengers. Great threat, wherein the traction rope is broken due to the stress concentration generated by the twisting of the car lifting drive motor, which is one of the main threats causing the car to fall. [0003] As disclosed in Chinese patent CN106865394B, a fall-preventing vertical elevator includes a car and a counterweight device for balancing the car. The counterweight device includes a counterweight body that moves up and down along the corresponding inner wall of the elevator shaft. , a counterweight ...
