Home elevator and car frame thereof

Abstract

The invention relates to a home elevator and a car frame thereof. The car frame comprises two vertical columns, the lower end of one vertical column is directly connected with a left holding beam which extends front and back, the lower end of the other vertical column is directly connected with a right holding beam which extends front and back, and only a front cross beam, a diversion sheave beam and a back cross beam which are sequentially arranged from front to back are connected between the left holding beam and the right holding beam in a bridge connection mode. The included angles between the diversion sheave beam and the left holding beam as well as between the diversion sheave beam and the right holding beam are 15-30 degrees, and diversion sheaves capable of leading a steel wire rope from the lower positions of the diversion sheaves are arranged on the diversion sheave beam. The front cross beam and the back cross beam are perpendicularly connected at the end portions of the left holding beam and the right holding beam correspondingly, and the front cross beam and the back cross beam are connected with each other only through the left holding beam and the right holding beam. An original lower beam is omitted, an integral holding frame composed of the left holding beam, the right holding beam, the front cross beam, the diversion sheave beam and the back cross beam directly supports an elevator car, therefore the structure of the car frame is simplified, and the compactness of the car frame is improved.

Description

technical field [0001] The invention belongs to the field of elevators, in particular to a household elevator and its car frame. Background technique [0002] With the vigorous development of my country's private villa market, the demand for related home elevators is also increasing. However, the common home elevators currently on the market have the following problems: 1. The overall structure is complex and poor in compactness; . [0003] The most common home elevator structure on the market is basically designed to imitate the traditional machine room structure. For the imitation of the traditional machine room structure, the car frame includes three parts: first, a rectangular frame composed of upper beams, lower beams, and columns. To complete the guidance of the car system; second, the bracket assembly used to support and fix the car; third, the car bottom return rope pulley and its wheel beam assembly arranged at the lower part of the car frame are used to complete ...

AI Technical Summary

Problems solved by technology

However, the common home elevators currently on the market have the following problems: 1. The overall structure is complex and poor in compactness;

This structure takes up a lot of space in the hoistway, the overall structure is complex, and the compactness is poor, and the guiding and hanging parts of the elevator are set separately, so that the central guiding and hanging can not be realized at the same time, the overall operation effect of the elevator is poor, and the riding comfort is low.
