Stop position detection device for elevator

Abstract

The invention provides a stop position detection device for elevator, which is capable of preventing the long strip shaped piece from hooking the stop position detection board without any special operation. In the stop position detection device for elevator, a stop position detector (10) is disposed on one side of the elevator cage driven in the hoist trunk, a stop position detection board (8) is convexly disposed at the stop position of the elevator cage on one side of the hoist trunk. The stop position detection board is opposite to the stop position detector (10), making the stop position detector (10) execute operation of stop position detection of the elevator cage. A projection arrangement portion (8B) of the stop position detection board (8) projecting to the elevator cage is arranged in a manner capable of inclination, which is capable of inclination under a load over the predetermined load, and returning to the original state under elasticity of a spring (9) when the load is removed.

Description

technical field [0001] The invention relates to a parking position detection device of an elevator, which is used for detecting the parking positions of an elevator car running in an elevator passage on each parking floor. Background technique [0002] Generally speaking, an elevator is composed of an elevator car, a counterweight, a main sling, a balance sling, and a lead wire. In the elevator with the above-mentioned structure, if the lifting stroke of the elevator is very long, when an earthquake or strong wind occurs, the building will shake substantially laterally, which will cause various long strips such as slings or leads This phenomenon is particularly noticeable in buildings with flexible structures such as super high-rise buildings. As a result, the above-mentioned elongated piece may be hooked together with various equipment in the hoistway. When the elongated piece is hooked to the liftway equipment, in addition to damaging the liftway equipment or causing dam...

AI Technical Summary

Problems solved by technology

Therefore, since it is necessary to respectively set the stop position detection board of the detection device on each parking floor of the elevator car in the elevator passage, the number of the stop position detection boards is large, and the stop position detection board protrudes into the elevator passage, thereby, There is a problem that it may be easy to catch on a long strip like the above
