Abstract
The invention relates to a ladder way guide rail of an escalator, which comprises a main wheel guide rail, an auxiliary wheel guide rail, a main wheel return rail and an auxiliary wheel return rail, wherein the main wheel guide rail comprises an upper horizontal part, an inclined part, a circular arc-shaped first transition section positioned between the upper horizontal part and the inclined part, and a circular arc-shaped second transition section positioned between the lower horizontal part and the inclined part, the curvature radius of the first transition section is 2600-2700 mm, and the curvature radius of the second transition section is 2000-2100 mm; the curvature radius of the arc-shaped first transition section is increased to 2600-2700 mm, and the curvature radius of the arc-shaped second transition section is increased to 2000-2100 mm, so that under the working load required by national standards, the wheel pressure of the step main wheel is remarkably reduced, the wheel pressure is in the bearing range of wheel design, the design requirement is met, meanwhile, the whole ladder operation noise and vibration are reduced to some extent, and the operation quality of the whole ladder is improved.
Description
Technical field
The present invention relates to a kind of terraced guide rail of escalator.
Background technology
Escalator is a kind ofly to have on the circulating motion ladder road direction or the driven by power equipment of downward-sloping conveying people, and it is big that it has traffic capacity, and it is even to transport passenger flow, because it has the characteristics of continuity work to be widely used in the public place that the stream of people comparatively concentrates.The terraced guide rail of escalator comprises major-minor whole guide rails of taking turns, returns rail and corresponding the support.The ladder road is an osed top circulating system, divides top ladder road system and ladder road, bottom system, dragging chain, turret wall part.The effect of escalator slide rail system is to guarantee that step is according to projected path.The escalator of the especially big height of escalator, because its hoisting depth increases (as being increased to 15 meters from 6 meters), whole terraced load increases, the major-minor wheel load that is produced of taking turns of step increases thereupon, thus the destruction of causing ladder sprocket wheel causes accident to take place.The increase of whole ladder operation noise, vibrations all influences the running quality of whole ladder.
Summary of the invention
The terraced guide rail that the purpose of this invention is to provide the little escalator of a kind of major-minor wheel load.
The present invention is implemented by the following technical programs: a kind of terraced guide rail of escalator, comprise that main wheel guide rail, jockey pulley guide rail, main wheel return rail, jockey pulley returns rail, described main wheel guide rail comprises horizontal part, goes up horizontal part, rake, first transition phase of the circular arc on described between horizontal part and the rake, second transition phase of the circular arc between described horizontal part down and rake, the radius of curvature of described first transition phase is 2600～2700 millimeters, and the radius of curvature of described second transition phase is 2000～2100 millimeters.
The radius of curvature of described first transition phase is preferably 2700 millimeters.
The radius of curvature of described second transition phase is preferably 2100 millimeters.
Compared with the prior art the present invention has following advantage: the present invention is increased to 2600～2700 millimeters by the radius of curvature with the first circular-arc transition phase, the radius of curvature of the second circular-arc transition phase is increased to 2000～2100 millimeters, like this under the working load that GB requires, the wheel of step main wheel is pressed with significant decline, it is taken turns and is pressed in the wheel design-calculated carrying scope, meet design requirement, whole simultaneously ladder operation noise, vibrations all reduce to some extent, have improved the running quality of whole ladder.
Description of drawings
Accompanying drawing 1 is the structural representation of terraced guide rail of the present invention;
Accompanying drawing 2 is the top scheme drawing of terraced guide rail of the present invention;
Accompanying drawing 3 is the bottom scheme drawing of terraced guide rail of the present invention;
Wherein: 1, main wheel guide rail; 2, jockey pulley guide rail; 3, main wheel returns rail; 4, jockey pulley returns rail; 11, go up horizontal part; 12, following horizontal part; 13, rake; 14, first transition phase; 15, second transition phase.
The specific embodiment
Terraced guide rail as a kind of escalator of Fig. 1～shown in Figure 3, comprise that main wheel guide rail 1, jockey pulley guide rail 2, main wheel return rail 3, jockey pulley returns rail 4, main wheel guide rail 1 comprises horizontal part 11, goes up horizontal part 12, rake 13, at first transition phase 14 of the circular arc between last horizontal part 11 and the rake 13, descending second transition phase 15 of the circular arc between horizontal part 12 and the rake 13, wherein each guide rail all is provided with the pressure rail with the top of returning rail, can make step pulsation-free operation more like this, each guide rail is connected by turret wall with returning between the rail.
Wherein, the radius of curvature of first transition phase 14 is 2600～2700 millimeters, and the radius of curvature of second transition phase 15 is 2000～2100 millimeters.
Make like this and main wheel wheel drops also can satisfy load request simultaneously.
The radius of curvature of selecting first transition phase 14 in the common engineering for use is 2700 millimeters, and the radius of curvature of second transition phase 15 is 2100 millimeters.
According to the requirement of GB GB16899-1997 " escalator and the manufacturing and installation safety standard in human nature road automatically ", the radius of curvature of the circular arc transition phase of escalator from the angled section to the horizontal section should satisfy:
R 〉=1.0m during V≤0.5m/s
R 〉=1.5m during V＞0.5m/s
So this escalator top and the bottom design concept is fit to product demand, real-world operation is respond well, the requirement that every technology, index of quality are up to state standards.
