Abstract

The invention discloses an ultimate limiting device which comprises a first speed-reducing switch, a second speed-reducing switch, a limiting switch, an ultimate switch, a position switch bracket used for fixing a position switch, and a limiting bow rack mounted on a car frame, wherein the first speed-reducing switch and the second speed-reducing switch are both forced slowdown switches; from bottom to top, the first speed-reducing switch, the second speed-reducing switch, the limiting switch and the ultimate switch are connected with a guide rail at the highest layer of a shaft in sequence through the position switch bracket; and meanwhile, from up to down, the first speed-reducing switch, the second speed-reducing switch, the limiting switch and the ultimate switch are connected to the guide rail at the bottom layer of the shaft in sequence through the position switch bracket. In the ultimate limiting device, by adopting the position switch bracket and the limiting bow rack, the position switch and a bow can be simply and conveniently mounted and maintained.

Description

technical field [0001] The invention relates to an elevator safety protection device, in particular to a car overrun protection device. Background technique [0002] During the operation of the elevator, when the elevator reaches the highest floor or the bottom floor, in order to prevent the elevator from malfunctioning and continue to run, causing the car to jump to the top or the pit accident, it is necessary to install the car overtravel protection device on the top and bottom floors of the well. In the prior art, the overrun of the car is prevented by installing a forced slow speed switch, a limit switch box and a limit switch, but the installation is very complicated, and the maintenance and adjustment after failure are all cumbersome. Contents of the invention [0003] Purpose: The present invention provides a limit limiting device aiming at the deficiencies of the prior art. [0004] Technical solution: In order to achieve the above object, the present invention ad...
