Problems solved by technology

[0004] However, there are some basic structural problems in the knapsack elevator. For example, the load of the car guide shoe is very large, so the rolling guide shoe must generally be used, and the cost is high; Contact with the stressed outer rubber will produce short-term deformation, and the comfort of the elevator will decrease significantly when it starts to run
Other problems are that the force on the guide rail becomes larger, so it is necessary to use a larger guide rail, etc.

Abstract

The invention discloses an elevator device, which includes a car, a drive device, a counterweight or cable tightening device, a cable connecting the car and the counterweight or cable tightening device, a speed limiter for monitoring the speed of the car, a limiter cable for transmitting the motion of the car, a limiter cable tightening device, a car guide rail and a counterweight guide rail for leading the car and a counterweight to move, and a lifting channel for containing the car, the drive device, the counterweight or cable tightening device and the cable, wherein, the limiter cable tightening device is arranged at the lower end of the lifting channel with the car or the counterweight guide rail as the a leading guide rail. The invention can make sure the eccentric force of a guide shoe and the guide rail, simplifies a guide structure of the limiter cable tightening device, reduces the cost, and meanwhile, results in more flexible structure deployment of the mechanical structure of the elevator and reduces the civil engineering dimension.

Description

technical field [0001] The invention relates to an elevator device, in particular to a machine room-less elevator device. Background technique [0002] Elevator installations are generally equipped with components to prevent the elevator from overspeeding, including detection components to detect the overspeed state of the elevator and action components to decelerate the elevator. The parts that detect the overspeed state of the elevator generally use a speed limiter, and its auxiliary parts are the speed limiter cable and the cable tensioning device. The speed limiter cable is connected to the car to transmit the speed of the car to the speed limiter. The cable tensioning device is used to prevent the cable from shaking when the elevator is running, colliding with the inner parts of the hoistway, or causing damage to the speed limiter or other related components. Misoperation. [0003] The speed governor and the cable tensioning device of the existing elevator device are ...
