Switch-multiplexed elevator leveling detection device and detection method

Abstract

The invention discloses a switch-multiplexing elevator leveling detection device and a detection method. The switch-multiplexing elevator leveling detection device comprises two leveling and re-leveling position detection multiplexing switches mounted at a car roof, a leveling and re-leveling position detection shift switch mounted at the car roof, a concave position detection mark plate matched with the multiplexing switches and a switch shift mark plate matched with the shift switch. The leveling and re-leveling position detection multiplexing switches are arranged in the same vertical direction in a spaced mode. The leveling and re-leveling position detection shift switch is arranged on the sides of the two multiplexing switches and is at the same distance with the two multiplexing switches in the vertical direction. A re-leveling position detection area is arranged in the concave part of the middle of the concave position detection mark plate, and leveling position detection areas are arranged on the two sides of the concave part. After the switch shift mark plate enters a detection gap of the shift switch, the detection switches are shifted from leveling position detection to re-leveling position detection. The number of the switches is decreased, the cost of the whole device is reduced, and the function of leveling and re-leveling detection can be accurately achieved.

Description

technical field [0001] The invention relates to a device and method installed in an elevator car and a hoistway for detecting the position of the car at a landing, and specifically belongs to a switch-multiplexed elevator leveling detection device and detection method. Background technique [0002] With the continuous deepening of the urbanization process, more and more high-rise buildings have begun to rise in the city, and the architectural space of the city is continuously extending in the vertical direction, and the floors are getting higher and higher. At present, in the elevator industry, the device and method for leveling (that is, when the car is close to the landing, the car sill and the floor sill reach the same plane) detection are usually carried out by means of a device and method in which the shaft partition and the car top leveling switch cooperate. [0003] At the same time, the higher the floor of the building, the longer the total length of the steel wire r...

Problems solved by technology

When the detection device detects, the two leveling position detection switches 10 and the two re-leveling position detection switches 20 respectively provide independent leveling signals DZU, DZD and re-leveling signals RLU, RLD, so that the detection device must be It has a completely independent set of leveling position detection switches and a set of re-leveling position detection switches, so the cost is relatively high
