Elevator equipment

Abstract

The invention provides elevator equipment without any mechanical room, but with a novel position exceeding prevention mechanism. The equipment at least prevents the elevating and lowering movements of an elevator car from exceeding specified positions when no position limiting switch is provided. The elevator car is provided with at least three unit stopping detectors each having a light emitting part and a light receiving part. Pairs of unit stopping detectors in different combinations are selected from the three unit stopping detectors for the lowermost floor, the common floors, and the uppermost floor respectively, and stopping detecting plates which block light between the light emitting parts and the light receiving parts of each selected pair of unit stopping detectors are arranged in elevating and lowering passages of elevator lobbies of the lowermost floor, the common floors, and the uppermost floor. In such a way, the lowermost floor, the common floors, and the uppermost floor can be determined according to the combinations of the unit stopping detectors. Therefore, the position limiting switch is not needed and the manufacture cost is lowered.

Description

technical field [0001] The invention relates to elevator equipment, in particular to an elevator equipment with a stop detection device. Background technique [0002] Elevator equipment usually consists of an elevator car, a counterweight, a main sling, a balance rope, and a tail cable. Furthermore, the elevator installation has a stop detection device which detects the stop positions of the elevator car at the individual floors. In the parking detection device, a parking detector having a light-emitting part that outputs light and a light-receiving part that receives the light is provided on the side of the elevator car, and a detection plate is provided at the parking position of the elevator car on each floor on the elevator passage side (hereinafter referred to as "stopping detection plate") detects the position of the elevator car (detection of a stop position) by blocking the light output from the stop detector with the stop detection plate.

AI Technical Summary

Problems solved by technology

[0017] In the elevator equipment having the above-mentioned structure, it is necessary to provide the limit switch bracket 12, the limit switch 9, the limit cam 11, etc. for constituting the limit switch mechanism, so there is a problem that the manufacturing cost will increase.

In addition, in order to install the limit switch bracket 12 and the limit switch 9, etc., it is necessary to reserve the space required for installation, so when installing other equipment such as the safety device 15, the control device 16, and the tail cable 18, the existing installation space will be affected. limit problem

[0018] In addition, in the parking detection device of the elevator equipment, it is necessary to install the detection plate support 23 (and sometimes the limit switch support 12) for constituting the parking detection device. There is a problem that the installation work for each floor is very troublesome, including the alignment work of the installation position (height and flatness, etc.)
