AI Technical Summary

Technical Problem

Traditional passenger elevators occupy a large pit space due to the car floor and car frame structure, which is complex to install and difficult to replace vibration damping pad components, affecting elevator comfort and maintenance efficiency.

Method used

A new installation structure for the car frame and car bottom is adopted, including a car bottom limiting component, a buffer layer, a support component and a counterweight. The traditional bracket is eliminated. The flexible buffer layer and the ring structure enhance the vibration reduction effect. The adjustment rod facilitates maintenance, and the position of the counterweight can be adjusted to improve static balance.

Benefits of technology

It reduces the space occupied in the pit, simplifies the installation process, improves the comfort and ease of maintenance of the elevator, enhances mechanical strength, and is suitable for use in heavy-duty elevators.

Abstract

This invention belongs to the field of elevators, specifically relating to an installation structure for an elevator car frame and car bottom. It includes a car frame, a car bottom limiting component, a car bottom, and two sets of support components. The car frame includes two left and right straight beam components, an upper beam component, and a lower beam component. An installation slot is provided in the center of the lower beam component. The car bottom limiting component is inserted into the installation slot of the car frame and has four sides (front, back, left, and right), each with a flexible buffer layer. The car bottom is fitted onto the top of the car bottom limiting component. The two sets of support components are respectively fitted onto the front and rear sides of the lower beam component. Each support component includes a support mechanism fitted with the lower beam component and a vibration damping mechanism fitted onto the support mechanism. The vibration damping mechanism supports the bottom of the car bottom. This invention eliminates the traditional bracket structure, avoiding the problem of brackets occupying pit space, reducing the pit depth requirements for the car frame and car bottom, and saving construction costs.
