Description
Technical field
The utility model relates to a kind of folding step of escalator.
Background technology
Existing escalator generally installs and fixes the field of employment, and (as automatic upper and lower aircraft service is provided for the airport passenger) becomes escalator industry one problem to escalator how in the on-fixed field of employment.What existing escalator adopted is that gusseted fixed type step and step overturn to mode, because the restriction of its stair structure and steering mode, thickness of horizontal segment is about about 1 meter under it, use when the on-fixed field of employment because the machine hole can't be preset in the scene in the mode of existing escalator, make initial tread of staircase and on-the-spot ground level can form drop about 1 meter, therefore can give use make troubles, generation hidden danger on the safety.The utility model will propose a kind of Foldable cascade, if this step is designing the thickness that adopts the translation mode turning operation can reduce horizontal segment under the escalator largely when using, the drop that reduces initial tread of staircase and on-the-spot ground level, and is convenient more in the use.
Summary of the invention
The purpose of this utility model provides a kind of Foldable cascade of escalator, this step can fully reduce the height of horizontal segment under the escalator when horizontal segment adopts translation mode to turn to down, become possibility thereby make the passenger both staircase can be climbed up directly, in order to improve convenience and the safety that escalator uses in the on-fixed field of employment by a visite road.
The technical solution of the utility model is: a kind of folding step of escalator, comprise pedal assembly, kickplate assembly and the main axle of fixing with the pedal assembly bottom, described kickplate assembly comprises kickplate assembly and following kickplate assembly, the upper end of described upward kickplate assembly and pedal assembly are hinged by articulation piece away from an end of main axle, be fixed with support arm on the kickplate assembly under described, one end and the pedal assembly of described support arm are rotationally connected, described collapsible step also comprises the swing arm with arc chute that an end and main axle are rotationally connected, the other end of described swing arm is equipped with accessory whorl axle and controlled lock hook assembly, described down kickplate assembly is provided with the slide-bar with the arc chute sliding block joint, described controlled lock hook assembly be provided with can with the latch hook of described slide-bar snap-lock.
The further technical scheme of the utility model is: the jointed shaft of described support arm one end and articulation piece is rotationally connected, and the other end and slide-bar are rotationally connected, and the support arm middle part is fixed with following kickplate assembly.Described articulation piece comprises that also two ends sheathed on the jointed shaft are supported in the torsion spring on pedal assembly and the last kickplate assembly respectively.
Also be provided with the regulation and control roller that be arranged in parallel with slide-bar on the described support arm.
Described regulation and control roller be located at described support arm with slide-bar bonded assembly one end on.In the process that the superimposition of step receipts is opened, the regulation and control roller moves in specific track, by simultaneously main wheel, accessory whorl, the corresponding separately running orbit of regulation and control roller being designed, can make step step pedal in receiving the superimposition opening procedure remain level and load-carrying capacity is all arranged.
The downside of described swing arm is the plane, and when described collapsible step was in complete folded state, described downside was parallel with tread.Make step when lower level-end turns to, the downside of step swing arm cooperates the breach that can pulsation-free strides across between accessory whorl section of turning to and the main wheel section of turning to support roller, reduces bump and produces unexpected and increase the step life-span.
Be connected with steel rope between described kickplate assembly down and the last kickplate assembly.When descending the kickplate assembly superimposed, can overcome torsion spring elastic force by the last kickplate assembly of steel rope pulling and receive folded.
The subject activity of described latch hook is sheathed on the accessory whorl axle, also be arranged with on the described accessory whorl axle two ends respectively with the fixing returning spring of latch hook main body and accessory whorl axle, the main body radially outer of described latch hook is fixed with the roller parallel with slide-bar.When step was in the mode of operation of normally opening, latch hook latched on the slide-bar under the effect of returning spring elastic force firmly, made step stay open state reliably; When step need be folded by the open mode receipts, at first the control guide rail of this roller and this roller collided and is overcome the rotation of returning spring elastic force by jack-up, this roller belts moveable lock hook and lifts, discharges slide-bar, and it is folded to make step to receive.When step is opened by the receipts overlapping state, the control guide rail of this roller and this roller machine in due course collide and by jack-up, the drive latch hook overcomes the rotation of returning spring elastic force and lifts, when slide-bar arrives the latch hook position, the control guide rail of this roller falls this roller, and latch hook resets under the effect of returning spring elastic force and pins slide-bar.
The utility model advantage is:
1. the utility model step can fold, height during the utility model folded state will be far smaller than the height that generally rigidly fixes the formula step, make step reduce at the height of the section of turning to, especially the height at lower level-end reduces, especially being fit to portable escalator uses, alerting ability is good, makes things convenient for client's elevator up and down.
2. the folding step swing arm downside of the utility model is the plane, make step when lower level-end turns to, the downside of step swing arm cooperates the breach that can pulsation-free strides across between accessory whorl section of turning to and the main wheel section of turning to support roller on the terraced road, reduce bump and produce unexpected and increase the step life-span.
3. the controlled lock hook assembly of the utility model is made up of the roller of installing with bearing pin on latch hook main body with latch hook and the latch hook main body, and is simple in structure, the reliability of service height.
