Door without sill and stereo garage thereof

Abstract

The invention relates to a door without a sill. The door comprises an outer door panel and an inner door panel. The bottom end of the door is installed on the ground or the floor surface, and the topend is suspended on a horizontal frame. Fixed guide wheels are arranged on the ground or the floor surface. A guide wheel mounting plate with moving guide wheels is disposed on the outer door panel. An outer door track and an inner door track are disposed on the horizontal frame, and the outer door panel and the inner door panel respectively slide on the outer door track and the inner door track through a door panel hanging pulley block. An inner driving motor, a driving wheel assembly, an inner door belt pulley, an outer door belt pulley, an inner belt and an outer belt are also disposed on the horizontal frame. An inner lower belt connecting frame and an outer lower belt connecting frame are respectively disposed on down sections of the inner belt and the outer belt and connected with the door panel hanging pulley block. A stereo garage using the door is further disclosed. The door has the advantages of door opening and closing quick response, high operation efficiency and low maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of automatic garage doors, in particular to a door without a sill and a three-dimensional garage. Background technique [0002] Since the beginning of the 21st century, with the rapid development of the urban three-dimensional garage industry, the safe operation of mechanical three-dimensional parking garages has become more and more important. Automatic garage doors are widely used in the construction of three-dimensional garages. There are various forms of garage doors, but the overall level is relatively backward, the response of opening and closing doors is slow, and the maintenance cost is high. Please also see the Figure 1a , Figure 1b and figure 2 What is shown is a common bifold garage door with a sill, including an outer door panel 1', an inner door panel 2' and a door operator 4' that drives the inner and outer door panels to slide, and a sill 3' is set on the ground. Tracks are arranged in...

AI Technical Summary

Problems solved by technology

Because the garage door panels (the outer door panel 1' and the inner door panel 2') need to be positioned on the track of the sill 3', and the track of the sill 3' is frequently rolled by the cars entering and leaving the garage, it is easy to break, deform and damage, and the wheel belt The sand that enters will also block the track, causing the garage door to fail to open and close, requiring frequent cleaning and maintenance
