Abstract

The invention discloses a double insurance elevator, which comprises a capsule (17), a counterweight and a guide rail (18), wherein the capsule (17) is provided with an elevator speed limiter (19), the side edge of the capsule (17) is provided with safety forceps (21), and the guide rail (18) is provided with an installation device (1) and a brake device (10). The installation device is arranged additionally on the guide rail of the elevator, a coding belt is arranged on the installation device, and thus an information error code is prevented as the coding belt does not need to be tensioned excessively and a narrower high-information density coding belt can be used. The brake device is added, another protection is provided for the elevator, when the running speed of the elevator exceeds 19%, the elevator speed limiter and the safety forceps work, the brake device also works at the same time, the elevator slide phenomenon caused by sudden failure of the elevator speed limiter and the safety forceps is avoided, and thus the elevator is safer and more reliable.

Description

technical field [0001] The invention belongs to the field of floors, in particular to a double safety elevator. Background technique [0002] Elevators can be used to transport passengers, goods between different floors of a building. The elevator is divided into two parts in the elevator shaft, namely the car and the counterweight, and the car and the counterweight move in opposite directions along the guide rail of the elevator shaft. [0003] A magnetic tape is arranged on the guide rail in the elevator shaft, and a magnetic head is arranged on the car, and the parking floor information on the magnetic tape is read by the magnetic head. As the tape curves across the elevator shaft, it is easy to lose information. In order to avoid information loss as much as possible, it is necessary to make the magnetic head and tape as wide as possible, which not only increases the cost, but also takes up a lot of space. [0004] However, during the operation of the elevator, the phe...
