Abstract

The utility model discloses a special-shaped automatic staircase. The utility model is characterized in that seven parts form a closed circulation. The closed circulation is formed by the process of the motion cycle of a pedal, which is composed of a transition portion I which is from horizontal circumferential motion to spiral ascending motion, a spiral ascending portion II, a transition portion III which is from the spiral ascending motion to the horizontal circumferential motion, a pedal downward turning portion IV, a spiral descending portion V, a transition portion VI which is from the spiral descending motion to the horizontal circumferential motion, and a pedal upward turning portion VII. The utility model has the advantages of small occupied architectural space, high flexibility, reasonable structure and stable performance. The special-shaped automatic staircase can coordinate and unify the internal-external arrangement of buildings conveniently.

Description

Special-shaped escalator

The utility model relates to a kind of escalator, specifically is a kind of escalator along the space curve operation.

At present because the variation of architectural style form, the high-rise that cylindrical or other curved have occurred, escalator along the space curve operation is selected form for architectural design person provides new transport channel, and the practical value of building and aesthetic values are further coordinated and unification.

Disclose a kind of curve escalator Chinese patent CN2038490U number, application for a patent for invention (CN1046506A) discloses a kind of curvilinear escalator.The former pedal is to be 2.7 meters circle rotation around radius, form (changeing 20 °), spiral rising (changeing 320 °), the disconnected motion in three districts of step disappearance (changeing 20 °) according to step, whenever the pedal that circles connects (this chain has only linkage function) by " universal chain ", turn over the revolution identical with number of floor levels, pedal rises to top layer by bottom, be 1.7 meters circumference again by radius, turn round 180 ° and drop to bottom, finish the once not busy circulation of envelope.The driving of staircase is not by " universal chain ", but disposes a driving chain in addition, drives " universal chain " and staircase motion through block.Every floor is established a cover actuating device, makes driven in synchronism.The latter is made of a huge cylinder and a cylindrical cam, have the axial groove identical on the cylinder with the pedal number, have in the groove and pedal bonded assembly slide block, when cylinder rotated a circle with respect to fixing cylindrical cam, pedal was finished horizontal circular movement, spiral rising, horizontal circular movement, circulation of spiral decline under action of cam.

More than two kinds of escalator weak points be that to take space big, the alerting ability and the coordinating and unifying settled in building are poor.In addition; CN2038490U needs driving chain and " universal chain " to work simultaneously just to drive pedal travel; more complicated on the interactively of drive mechanism and power; and the pedal cycle route is oversize; space motion hands over the position too much; in case break down, each floor is all shut down, and whole building transport channel blocks.

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provide a kind of rational in infrastructure, stable performance, applicability strong, take the little special-shaped escalator of space.

Below in conjunction with accompanying drawing and embodiment shown in the drawings content of the present utility model is described in detail, but content of the present utility model is not limited to shown in the accompanying drawing.

Fig. 1 is the front view of structural representation of the present utility model;

Fig. 2 is the birds-eye view of structural representation of the present utility model;

Fig. 3 is the expansion drawing of structural representation of the present utility model;

Fig. 4 is a chain structure schematic diagram of the present utility model;

Fig. 5 is a sectional schematic diagram of the present utility model.

The utility model is by electrical motor (1), retarder (2), head sprocket (3), guide rail (4), chain (5), frame (6), pedal (7), roller (8), fagging (9), handrail (10), pivot pin (11), cantilever beam (12), plaque (13) constitutes, the motion cycle of pedal (7) moves to spiralling transition portion I by horizontal circumference, spiral rising part II, spiral rises to the transition portion III of horizontal circular movement, turn over IV under the pedal, spiral sloping portion V, spiral drops to and turns over seven parts of VII on horizontal circular movement transition portion VI and the pedal and constitute a close cycle, pedal (7) is fixed on the chain drive-belt by little axle, chain (5) connects pedal (7) and drags it by pivot pin (11) and moves along guide rail (4), two pairs of supporting rollerns (8) before and after on pedal (7), being provided with, support it in the guide groove of guide rail (4), guide rail (4) is bearing on the fagging (9), fagging (9) is fixed on frame (6) vertically on the angle steel, and frame (6) is bearing on the cantilever beam (12) on the cantilever that embeds on the building wall.

Described chain (5) can freely rotate around orthogonal diaxon; The space motion track of pedal is retrained by four tracks, and the vertical projection of its path of motion is one section circular arc (also pressing other curvilinear figure of building requirements); The pairing angle in circular segment of staircase vertical projection, can according to story height (＞4m), the width of pedal (in widely be 300-400mm), the discrepancy in elevation (＜200mm of every grade of ladder, when the pedal spiral rises), the pedal number (＞3) of horizontal circular movement etc. can be the angle that 60 ° or 90 ° or 120 ° or 270 ° or 360 ° or other and building aesthetic requirement adapt.The type of drive of described staircase can adopt strand or double-stranded the driving.

Principle of work of the present utility model is as follows, driving is by electrical motor (1) retarder (2) to be passed in motion, again by reducer output shaft through chain (5) transmission head sprocket (3), head sprocket (3) drives chain drive-belt (5), pedal (7) is fixed on the chain drive-belt (5) by pivot pin (11), move with chain (5), this chain can freely rotate around orthogonal diaxon, it have connect pedal and with two kinds of functions of the meshing driving pedal travel of sprocket wheel, when chain is worked, drag line of action of force under any circumstance all by the symmetrical center line of chain, good with the stationarity that guarantees it.The path of motion of pedal (7) is retrained by guide rail (4).The pedal travel circulation and the driving of each floor of escalator have autonomous system of one's own, constitute a staircase unit, and the staircase of each floor can be connected on settling successively, but noninterference.By the requirement of architectural composition, the staircase unit of contiguous floors also can divergence, but separated by a distance.

Compared with prior art, because this utility model employing chain drive-belt can be around mutually vertical Diaxon freely drive total two kinds of functions that connect pedal and the meshing driving of sprocket wheel; They are four years old Bar forms four guide rails of pedal space motion path, can form according to the building actual state Upright projection is circular arc or other shaped form; The corresponding angle of circumference of staircase upright projection, Can in 90-360 ° scope, be adjusted into the angle attractive in appearance with building the phase coordination. So It is little that the utility model takies space, the convenient and inside and outside layout of the building coordinating and unifying, spirit Active big, have rational in infrastructure, stable performance, characteristics that applicability is strong, this abnormity staircase Can be configured in circular (or other shaped form) inwall of building, outer wall or separately arrangement.
