Elevator limiting device and elevator

Abstract

The invention discloses an elevator limiting device and an elevator. The elevator limiting device comprises a limiting component, a triggering component and a buffer. The limiting component is arranged on the side face of an elevator car and comprises a first component and a second component, wherein the first component and the second component are fixedly connected in an included angle. The firstcomponent is provided with a first pushing part capable of abutting against the side face of the elevator car, and the second component is provided with a second pushing part which pushes against theside face of the elevator car during elevator running. The triggering component is arranged on the shaft wall of the bottom of an elevator shaft. The buffer is arranged at the bottom of the elevatorshaft and below the limiting component. When the elevator car falls to the bottom of the elevator shaft, the front end of the first component touches the triggering component, so that the limiting component rotates, the first pushing part is attached to the side face of the elevator car, and the second component is pressed on the buffer. The buffer is arranged below the limiting component, so thatthe space occupied by the buffer on the bottom of the elevator shaft is saved, and the space arrangement is facilitated.

Description

technical field [0001] The invention belongs to the technical field of elevator braking, and relates to an elevator limiting device and an elevator using the elevator limiting device. Background technique [0002] At present, the elevator design basically includes the elevator car, the elevator shaft, the shaft pit and the elevator car buffer installed inside the shaft pit. Among them, the buffer is the device that finally provides safety protection for the elevator. Just below the elevator car, so that when the elevator car exceeds the bottom floor due to accidents such as wire rope breakage during the downward movement of the elevator car, the elevator car can be buffered to prevent the elevator car from directly hitting the bottom of the elevator shaft. Keep passengers safe. [0003] However, in existing elevators, details can be found in figure 1 , they all need to design a special bottom space for the buffer. At the same time, combined with the need to consider the bu...

[0003] However, in existing elevators, details can be found in figure 1 , all of them need to design a special bottom space for the buffer. At the same time, combined with the need to consider the buffer distance and the height of the buffer itself, the buffer occupies more bottom space, which leads to the use of existing methods to design elevators. normal design use of space
