Description
Technical field
This utility model is related to the parts of escalator, especially a kind of step knot for rotary escalator
Structure.
Background technology
Escalator has been widely used in the places such as large-scale shopping square, airport and railway station.Now in all parts of the country
All building the public transport places such as subway, railway station, the demand of escalator is also quickly being increased.For some high-end markets
Cooperation architectural design aesthetics, adopts rotary escalator sometimes.The design of the structure for conveying of this rotary escalator
The escalator designing with respect to existing linear type with manufacture, will be complicated and much more difficult in structure and manufacture.How
Guarantee the smooth stable operation of this rotary escalator, merit our study.
Because the running orbit of rotary escalator is along arc direction hoisting depth, and there is inner side and run outside slowly
Fast own characteristic is run in side, and guide track system is necessary to be designed to interior follower rail highly different sometimes, thus linear type is automatic
Stair structure on staircase cannot use wherein.Therefore, urgently develop a kind of step for rotary escalator at present
Structure.
Content of the invention
In view of this, the purpose of this utility model is to provide a kind of stair structure for rotary escalator.
For reaching above-mentioned purpose, this utility model employs the following technical solutions：
A kind of stair structure for rotary escalator it is characterised in that：Axially extend from the inside to the outside including itself
And the step axle that is obliquely installed from low to high, described step axle is provided with step, the inside and outside two ends of described step axle lead to respectively
Cross a bearing pin and be connected with a step chain, be located at two described step chains inside and outside two ends of described step axle respectively
Running height is a low high setting, and the inner side of every described bearing pin has coaxially connected with described step axle bending after bending
Linkage section.
Preferably, described bending linkage section is connected by jump ring with described step axle.
Preferably, the outside of every described bearing pin is all connected with roller, and described roller runs along guide track system.
It is highly preferred that the interior side wheel on the described roller described bearing pin that includes be connected to the inner of described step axle and company
Outer side wheel on the described bearing pin of the outer end being connected on described step axle, described guide track system includes supporting described interior side wheel
Inboard track and the follower rail supporting described outer side wheel, the height of the upper supporting surface of described follower rail is higher than described inner side
The upper supporting surface of guide rail.
It is further preferred that the rotary centerline of the rotary centerline of described interior side wheel and described outer side wheel is along level
Direction be arranged in parallel.
It is further preferred that be connected on the described bearing pin of the outer end of described step axle being also associated with side directive wheel, described
Side directive wheel runs along the lateral surface of described follower rail.
In a particular embodiment, the rotary centerline of described side directive wheel is vertically arranged.
Wherein, the intrinsic step axle sleeve of difference inside and outside described step axle, described step passes through described step axle
Set is fixed on described step axle.
The stair structure for rotary escalator that this utility model provides, by the step axle that is obliquely installed and
The bearing pin being connected with step axle two ends connects each step chain in left and right, makes inside and outside two step chains form certain height
Difference, thus reach the normal purpose run on the guide track system of rotary escalator.
Brief description
Fig. 1 is the perspective diagram of the stair structure of embodiment one.
Fig. 2 is that the stair structure of embodiment one removes the structural representation after step.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described in detail.
Embodiment one
Refer to Fig. 1 and 2, a kind of stair structure for rotary escalator, axially prolong from the inside to the outside including itself
The step axle 1 stretched and be obliquely installed from low to high and the step 8 being arranged on step axle 1, the inside and outside two ends of step axle 1 lead to respectively
Cross a bearing pin 3 and be connected with a step chain 2, be located at the operation of two step chains 2 inside and outside two ends of step axle 1 respectively
It is highly a low high setting, the inner side of described bearing pin 3 has coaxially connected with step axle 1 bending linkage section after bending, should
Bending linkage section is connected by jump ring 4 with step axle 1.In the present embodiment, step chain 2 is sleeve-barrel roollr chain structure.
Wherein, the intrinsic step axle sleeve 7 of difference inside and outside step axle 1, step 8 is fixed on by step axle sleeve 7
On step axle 1.The lower end of step 8 has the step roller axle 81 installing step roller.
The outside of every bearing pin 3 is all connected with roller, and described roller runs along guide track system.Described roller includes connecting
Outer side wheel on the bearing pin 3 of the interior side wheel 51 on the bearing pin 3 of the inner of step axle 1 and the outer end being connected to step axle 1
52, described guide track system includes supporting the inboard track 61 of interior side wheel 51 and the follower rail 62 supporting outer side wheel 52.Interior
The rotary centerline of the rotary centerline of side wheel 51 and outer side wheel 52 be arranged in parallel in the horizontal direction, has height between the two
Degree drop H.
