Description
Technical field
The present invention relates to have the escalator of ring ladder band, described ladder band is made up of the pedal of many interconnection, pedal comprises walking surface and leading flank and is connected on separately the side step chain herein, step chain drives around lower and upper steering position by means of actuating device, and pedal contains the pedal roller that is guided by a pedal rolling wheel guide rails at least herein.
Background technology
Among many such escalators are using.Steering position obtains with a chain wheel flutter or a pair of chain wheel flutter mode usually, and two lateral arrangement step chain of this ladder band are round wheel flutter guiding and driving.Also have multiple escalator, wherein the propelling of step chain is not to occur near the steering position, but before for example movable section or the back movable section.In such escalator, provide the guide rail of deflecting plate for example or basic semicircle to replace its chain wheel flutter, deflecting plate or guide rail are being followed the step chain rolling wheel guide rails respectively herein, so step chain roller movable section before the passenger conveyor in this deflecting plate or guide rail is reversed among the movable section in back herein.Aspect this, the term steering position is to cover all types of structures, i.e. chain wheel flutter, divert guide track or deflecting plate.
Escalator treadboards usually by a plurality of have being substantially of walking surface box-like member and the leading flank that in the escalator angled section, exposes constitute, the walking surface is also referred to as " trampling face ", and leading flank is also referred to as " riser ".Never also can seal at the escalator on period, but keep often opening wide the box residue side that the passenger exposes.This is particularly useful for pedal downside and pedal rear side with walking surface positioned opposite.Because reasons in structure is directly arranged usually regularly towards the pedal sidewall of step chain.Be not arranged to facing under the situation of leading flank at box-like treadle component rear wall, directly the box sidewall towards step chain has the triangle that dwindles towards the bottom often, so with near the leading flank pedal thickness relatively, this only has less relatively thickness in portion zone thereafter pedal.Because these measures can significantly reduce weight and material requirement.
Usually with pedal shaft pedal is fixed on the step chain.Pedal shaft extends through pedal body usually and is connected on the step chain with two free end.The connection location of pedal on step chain generally places the pedal rear end place relative with leading flank, and as common not special thickening mentioned above.Pedal is usually with a kind of material that can handle easily, and material such as aluminium, aluminum alloy or plastics that for example can extrusion molding be made.For example iron or steel are made and pedal shaft is with a kind of strong material.Pedal shaft is fixed on the pedal by means of the multiple suitable connection structure in the pedal rear end setting.For the demolition pedal on the step chain that often requires as maintenance, need remove pedal shaft from pedal with from step chain.Removing pedal from pedal shaft is common practice.Can become possibility near pedal shaft from the trailing flank relative because demolition makes like this with pedal walking surface, in turn-around zone, only have the place can be suitably making great efforts the demolition pedal, the distance between two pedals of described place even as big as make the maintainer can with two hands near and remove pedal from pedal shaft.Various situations can occur in the escalator maintenance, mobile therein ladder band is so that the demolition pedal is impossible or not to be desirable.Therefore constantly attempt changing in such a way the structure of escalator, so that can be with less relatively energy (effort) at the optional position of preceding movable section demolition pedal.As mentioned above, pedal rear end is thinner relatively.This means, be used for pedal is connected on the step chain and allows in any position on the step chain demolition pedal alternative structure owing to the space reason almost cannot realize.
Preventing of the diverse problem of escalator and the safety of escalator and incident is relevant.In escalator, pedal motion in very narrow " passage " usually separately, this passage is limited in side direction by the panel member that is called " skirtboard ".These skirtboards are arranged on the escalator frame rigidly, and pedal is with respect to this skirtboard motion.Keep very little for the space of reason between pedal and skirtboard of safety is essential, so that guarantee not have object or passenger's body part to draw in this space and be clipped in wherein really.Guarantee that very the requirement of narrow gap is relevant with high service expenditure.In some cases, it is impossible fully satisfying the safety requirements relevant with narrow gap.Except the base plate that provides with pedal travel is provided a kind of selection with this potential danger of reduction the narrow gap.For example, at US-A-4, a kind of like this removable bottom was described in 470,497.Shortcoming according to this base plate of prior art is: they protrude upward relative far away above the pedal walking surface in the escalator horizontal section (being entry position and exit position), or they have the structure of relative complex.
Summary of the invention
Therefore, the present invention is based on the purpose that obtains a kind of effective escalator, the structure of this escalator realizes like this so that be used for the pedal side direction is connected to enough spaces on the step chain (promptly pedal being fixed in the zone of step chain) on the pedal sidewall to provide, and can realize under the situation of above not mentioning shortcoming with the base plate of pedal travel.
Describe in the escalator of the present invention of type in beginning, this target reaches due to the fact that: pedal is fixed to the location arrangements of step chain near the leading flank of this pedal.Compare with near the prior art pedal is fixed to the pedal rear end face of step chain, the present invention proposes a kind of antipodal terms of settlement.If people follow the distance from lower inlet position to upper outlet position of pedal through the escalator of the transmission that makes progress, pedal occurs below the comb plate, comb joint at the place, entrance that is positioned at the basic horizontal position.In the walking surface of this place pedal is located substantially on a plane.After leaving this horizontal section, the motor path of pedal changes over the banking motion path gradually in the district is transported in the bottom, in the transport zone of top, be converted back into the horizontal motion path then, and pedal disappears at last below the comb plate, comb joint that is positioned at the exit point place in this zone.Walking surface at the motor path upper footboard of whole exposure keeps level attitude.This means, the horizontal throw between the walking surface of adjacent pedal from the outset only be zero to be increased to the ultimate range in the motor path angled section, reducing to again then is zero substantially.Correct level attitude by the pedal roller control pedal walking surface of pedal rolling wheel guide rails guiding.
According to prior art, in the district was transported in the bottom, the walking surface front end face that is positioned at this pedal front side raise gradually in adjacent low pedal walking surface.Similarly, this pedal front end face reduces in the district is transported on top again, till it and adjacent pedal are in essentially identical height.The present invention proposes a kind of diverse layout, this front end face " is held in place " therein, this relative with the front side at the same time pedal rear end face is by pedal roller guiding, so that in the district is transported in the bottom below the walking surface level of its " decline " at adjacent higher pedal.Similarly, this aft end face " rising " in the motor area, top, according to this sequence of motion, removable bottom can relatively easily be realized, and described base plate comprises a plurality of flanges, and in fact these flange lateral fixation are not protruding upward above the walking surface on the pedal and in the horizontally extending basically zone of ladder band.
According to the present invention, pedal is fixed on location arrangements on the sidewall in sidewall region, sidewall has relatively large surface in this district, so that can provide enough spaces to realize that the alternative connection of pedal on step chain arrange, that is to say pedal can be in the optional position of exposing the ladder tape section relatively easily the connection of demolition arrange.
Be preferably in pedal rear end face (promptly with pedal leading flank opposing end faces) and arrange the pedal roller.This causes being used for the relatively long throw of lever of pedal roller, so that realize firm, reliable and accurate guiding in the ladder band.
Move with pedal and the lateral lip member that forms a base plate part preferably is connected on the pedal at the escalator on period.In a particularly advantageous embodiment, these flange members are realized according to the shape that is similar to the circular sector body, and their center arrangement is on the pivot center of this pedal with respect to step chain.Flange member for example can integrally obtain with this pedal.As an alternative, but their also demolition ground or be rigidly fixed on this pedal.
The pedal roller is preferably led as follows by the pedal guide rail, so that move with respect to contiguous pedal, that is to say that the position that is positioned at a plane from two pedal walking surfaces substantially arrives the position that height h is departed from described walking surface relative to one another at escalator on period pedal.In this case, connection location is positioned near the leading flank and is arranged in this wise near the pedal leading flank basically, so that it offsets downward height h basically with respect to the walking surface of this piece pedal.This design is best, because the enough surfaces that are used for obtaining special connection structure embodiment can be provided on the pedal sidewall above the connection location.This structure is also best because can obtain especially relevant with the pedal roller that is arranged in the walking surface rather compact escalator structure.
As an alternative, connection location preferably is arranged near the leading flank of pedal, and is in the below slightly on walking surface.Term walking surface " below slightly " relates to the connection location that the upper side below that is located substantially on the walking surface is not more than half place of height h.Preferably select to be equivalent to 1/4th or the littler distance of height h.
The pedal roller preferably is connected on the pedal as follows, so that it is arranged in the walking surface.As indicated above, this pedal roller arranges that it is particularly advantageous combining with the connection location that offsets downward height h from the walking surface basically.Except thus obtain the compact structure, use the layout of this pedal roller can reach and another relevant advantage of demolition pedal simply in pedal walking surface.So that when the optional position of conveying channel demolition pedal, the pedal roller also is approaching easily when pulling down balustrade panel.If the pedal roller is positioned at the walking lower face, this just may go wrong in some cases.In the sort of example, the pedal roller places pedal to be fixed in the below of step chain position usually, and thereby is in below the step chain guide rail.This makes demolition difficult more significantly.
The most handy connecting arm of pedal roller is connected on the pedal.Connecting arm or be installed on the pedal with the component form that separates perhaps for example is manufactured in together with integrated member form and pedal by means of injection molding technique.
The pedal roller preferably is connected on the pedal in the mode that is arranged in the walking lower face.With regard to geom was considered, this layout was preferably used in connection location and is positioned at the pedal walking surface example of below slightly.The pedal roller also is connected on the pedal with connecting arm in this case.
