Elevator device

Abstract

The object of the present inventive elevator device is to reduce the depth of a pit in a hoistway, which has a rope 5 disposed along the crossing direction to a horizontal virtual axis 21 connecting a pair of guide rails 10 disposed oppositely to each other along a hoistway 7 for guiding both sides of a lifting car 1 stretched between a pair of sheaves 2 installed at the bottom part of the car, and lifting the car.The guide rails 10 are fixed to the bottom part of the hoistway, and a buffer 9 is installed on the bottom part of the hoistway so as to be separated by a specified distance from the projected plane of the rope 5 wound on the pair of the sheaves positioned at the bottom part of the car. By this, even if the car lowers fully to the state of full stroke of the buffer, a risk of the rope stretched between the sheaves interfering with the fixture of the guide rail is eliminated, and the depth of a pit can be reduced accordingly.

Description

technical field [0001] The present invention relates to elevator installations for transporting people or goods. Background technique [0002] In an elevator device installed in a building, etc., to transport people or goods, a machine room is usually provided on the roof of the building that communicates with the lifting passage. Various equipment necessary for the operation of the elevator device, such as a speed controller or a console. In addition, the hoisting machine moves the cable on which the carrying car is suspended on one side and the balance weight is suspended on the other side by traction, whereby the carrying car is raised and lowered. [0003] However, installing a mechanical room on the roof of a building will increase the height of the building by one story, and it will be affected by the restriction of the north slope or the restriction of sunlight, or the load will act on the top of the building, etc., which will affect the design of the building. , re...

AI Technical Summary

Problems solved by technology

However, since the bottom of the carrying car 1 and the cables 5 passing around the pulley 2 at the bottom must require a prescribed size, if on the contrary, the depth of the elevator shaft 16 is small, then the carrying car In case the box 1 falls until the buffer 9 is in the full range state, there is a danger that the cable 5 passing around the pulley 2 will interfere with the fixed guide rail 10 and the beam 12 supporting the buffer 9 will interfere

In addition, when the carrying car 1 falls, if there is an operator working in the elevator shaft 16, the place for the operator to retreat is limited, causing a safety problem.
