Hollow cage guide

Abstract

The invention discloses a hollow cage guide, which can save materials and has strong torsion deformation resistance and convenient installation. The hollow cage guide comprises a guide rail seat and a hollow guide rail body connected with the guide rail seat, wherein the guide rail body comprises a pair of parallel guide rail sides and a guide edges connected with the pair of guide rail sides. The cross section of the hollow cage guide encircles into a sealed hollow structure of the Chinese character tu. The invention is mainly used in low speed elevators.

Description

technical field [0001] The present invention relates to elevator guide rails, in particular to hollow elevator guide rails. Background technique [0002] Such as figure 1 As shown, an open-type hollow elevator guide rail, its structure includes: a guide rail body composed of a pair of parallel guide rail sides 1 and a guide side 2 connecting the pair of guide rail sides 1, the ends of each guide side 1 are connected There is a mounting edge 3. As we all know, the guide rails of an elevator are usually made of multiple such hollow elevator guide rails connected in series, and this kind of guide rails can only be connected in series through the method of external connection, that is: all the installation sides of the hollow elevator guide rails 3. It is very inconvenient to install on the external steel plate, which makes the straightness of the series-connected guide rails poor, resulting in increased noise in elevator operation; in addition, although the material of this h...

Problems solved by technology

As we all know, the guide rails of an elevator are usually connected in series by a plurality of such hollow elevator guide rails, and such guide rails can only be connected in series through the method of external connection, that is, the installation sides of all the hollow elevator guide rails 3. It is very inconvenient to install on the external steel plate, which makes the straightness of the series-connected guide rails poor, resulting in increased noise in elevator operation; in addition, although the material of this hollow elevator guide rail is much less than that of solid guide rails, However, the wall thickness of each side is still relatively thick, usually about 4 mm, and the weight per meter reaches 5 kg; and this hollow elevator guide rail has poor resistance to torsional deformation in the length direction.
