Abstract

The invention discloses an escalator. The distance between a forward step and a return step of the escalator is widened in the vertical direction, so that lower steps can also carry people. Extremely thin flat plate steps are designed, both surfaces are provided with comb racks and can be used, and a non-skid block is arranged on each flat plate step so as to carry people safely. A lip of a hand strap has an orientation angle of 180 degrees after being turned twice in one escalator and can be used in both forward travel and return travel. Through the escalator, the proportion of the usable part is greatly improved; in addition, the extremely thin flat plate steps are used and the radius of a driving wheel is small, so the escalator has the advantages of greatly reducing thickness, saving space, greatly reducing manufacturing cost and running energy consumption and running between two or more layers within one escalator in the forward travel and the return travel, along with flexibly transformable shape and multi-step linkage.

Description

A kind of escalator

Technical field:

The present invention relates to a kind of escalator, particularly the escalator of positive return step manned operation simultaneously.

Background technology

Existing escalator is made up of the handrail (belt conveyer of distortion) of terraced road (apron conveyor of modification) and both sides.Its major part has dull and stereotyped rank (or step), guide track system, drive system (comprising electrical motor, driving main shaft etc.), driving system (comprising conduction chain and sprocket wheel, speed reduction gearing, drg and intermediate drive link etc.), terraced road tightening device, guardrail and handrail, fishback, truss, staircase skeleton and electric system etc.Escalator has handrail by truss support on guardrail, dull and stereotyped rank single face has the broach bar, is used in combination with fishback.Ladder access is the trace step above the definition, below ladder access be the backhaul step, most existing escalator then; Because the operation at the trace step back side of backhaul step, the distance between two ladder accesses is too little, so can't mannedly move on the backhaul step; Causing has above the invalid operation of half step all the time; Dull and stereotyped rank single face has the broach bar, in the backhaul ladder access, has one of broach bar and faces down, only handrail use in the trace step of handrail; Moving sidewalk (promptly using the escalator on dull and stereotyped rank) is from security consideration, and the leaning angle of general terraced body is not more than 12 degree (GB-T207024-1997).On February 17th, 1998, CN87200850U, the CN2419190Y that announce February 14 calendar year 2001 and the Chinese utility model patent specification sheetss of announcing on December 24th, 2008 such as CN201169479Y of bulletin disclosed several kinds of bidirectional escalator or the load transfer devices that horizontal direction turns to.But in the vertical direction will realize that positive return can transport simultaneously or the terraced body degree of utilization of manned operation is still very low, and the problems such as the unresolved handrail long-term use of escalator that turn to of disclosed several kinds of horizontal directions.The tradition escalator is owing to the double-deck step stack of positive return ladder access on the vertical direction, and dull and stereotyped in addition rank (or step spare) are blocked up, make that the wheel flutter radius is big, and whole terraced body is thick; The ladder body back side is unloaded fully, wastes energy; Ladder type is single, and not team control of general run of thins interlock is unfavorable for adapting to different demands, also is unfavorable for practicing thrift and makes and operating cost.

Summary of the invention

The technical matters that the present invention will solve is to provide a kind of escalator; The positive return step is manned operation simultaneously all, make the degree of utilization of escalator higher, productive costs is lower, more energy-conservation during operation, ladder type is smaller and more exquisite with various, make and keep in repair easier.

In order to solve the problems of the technologies described above, the technical scheme that the present invention adopts is:

A kind of escalator; Have and the guardrail of the similar electric system of traditional escalator, drive system, driving system, truss, Armrest band, dull and stereotyped rank, trace step and backhaul step etc.; The trace step is positioned at the top of backhaul step; Under the drive of step tow chain, the running that moves in circles of trace step and backhaul step.Distance between the dull and stereotyped rank of moving the trace step wide and the backhaul step; Distance between the in the vertical direction of the dull and stereotyped rank of two steps is a 2.2-9 rice; Two sides, dull and stereotyped rank all can be used, and the two sides all has the broach bar, and the handrail lip is towards Rotate 180 degree between trace step and backhaul step.

After the distance of moving wide on the basis of traditional escalator on the vertical direction between trace step and the backhaul step, make the manned operation of people of to stand simultaneously on the positive return step.The minor increment of in the vertical direction is a standard with the people that can stand between the positive return ladder access, and promptly under the usual condition, the distance of two ladder access step face in the vertical directions is more than or equal to 2.2 meters.For example, be 25 when spending when the distance between the dull and stereotyped rank in the vertical direction of the dull and stereotyped rank of trace step and backhaul step is about 2.2 meters, leaning angle, the shortest distance between the dull and stereotyped terrace of two ladder accesses is about 2 meters up and down.Consider the elevator manufacturing cost and use cost, the distance between the dull and stereotyped rank in the vertical direction of the dull and stereotyped rank of trace step and backhaul step is advisable to be no more than 9m.In the full-load run of known automatic staircase test " because of it on to or down to operation almost with same power driving " (Huang Zhijian; " load transfer device ask and answer for maintenance "; China Machine Press, the 2004 [1], the 262nd page) so the uplink and downlink step of the present invention people's operation of standing simultaneously; The passenger is counterweight each other, helps more easily energy-saving run of escalator.Handrail in the lip turn-around zone between the positive return step, rotates lip towards 180 degree under the effect of steering hardware, but makes all handrail uses of every section ladder access.This type of turns to has plurality of devices to realize in the prior art; Preferred version be provided with array be in rotation lip that different angles become helical trajectory and equidistance towards the top guide wheel; Give handrail a path; Handrail forwards by top guide wheel pinching and along path, turns to purpose and reach lip with this, and the method turns to the long more handrail in interval to be not easy volume more and decreases.

As further improvement of the present invention, design a kind of dull and stereotyped rank, dull and stereotyped rank have limited slip block.Further, limited slip block is liftable also.Limited slip block and the synchronized operation of dull and stereotyped rank are fallen in non-manned bench.Can rise at manned bench limited slip block; Outstanding dull and stereotyped terrace 1-3 centimetre; Passenger's sole has increased the passenger and has stood in stability and safety on the escalator owing to having limited slip block to block or rubbing, and also makes the leaning angle of escalator to use the escalator on dull and stereotyped rank big than tradition.Take all factors into consideration dull and stereotyped rank width and human foot length, the installation of limited slip block is preferably the dull and stereotyped rank of no limited slip block and has the dull and stereotyped rank of limited slip block alternately to install, if promptly odd-order has limited slip block, and the no limited slip block of even-order then, or vice versa.

As further improvement of the present invention, dull and stereotyped rank thickness is 4-5 centimetre, with the material of making dull and stereotyped rank commonly used, adopts hollow structure, can reach the manned requirement of safety.Because dull and stereotyped rank are thin, width is also narrow, and then the radius of wheel flutter can dwindle the very big attenuation of terraced body thickness.

As further improvement of the present invention, the leaning angle of escalator be 12 the degree to 25 the degree, be preferably the 23-25 degree.Tradition moving sidewalk (promptly using the escalator on dull and stereotyped rank) is from security consideration, and the leaning angle of general terraced body is not more than 12 degree.The present invention makes leaning angle to strengthen owing to used these parts of limited slip block.Being 2.2 meters with the distance of the dull and stereotyped rank of positive backhaul in the vertical direction is example, and when leaning angle is 12 when spending, the minor increment on the dull and stereotyped rank of positive backhaul is 2.15 meters, and when leaning angle is 25 when spending, the minor increment on the dull and stereotyped rank of positive backhaul is 1.99 meters.The height of supposing two floor gaps again is 6 meters, and the leaning angle of known moving elevator is not more than 12 degree, and tiltedly the length of section will be greater than 28.85 meters for then terraced body.And the oblique section of the terraced body of escalator involved in the present invention is got the 12-25 degree with the angle of floor Horizon, and the then terraced body tiltedly length of section is about 14.20 meters to 28.85 meters.If the positive return ladder access is all manned respectively, calculate with manned respectively single ladder access, this kind escalator can mannedly use the ratio of part to be much higher than known escalator.

As further improvement of the present invention, escalator is controlled the many covers of a platform driving host drive step interlock at the most with a cover computerized control system.Can propose the possible situation of multiple installation escalator, on this principle basis, can also make up more trapezoidal.Existing software technology can be realized controlling the many covers of a platform driving host drive step interlock at the most with a cover control system." MICROCOMPUTER PROCESSING collection selected control system elevator: the work operation of elevator is the situation according to ridership, by MICROCOMPUTER PROCESSING, selects the optimum operation mode automatically." (Wang Fengxi etc., " elevator uses and ask and answer for maintenance " China Machine Press, the 2003 [1], the 15th page).In the escalator of many ladder interlocks of the present invention, when transshipping because of passenger flow volume increases like a drive motor, then by MICROCOMPUTER PROCESSING, automatic selection increases progressively the subsequent use drive motor midway of breakdown one by one and gives power-assisted, ensures that escalator normally moves; Otherwise, then successively decrease one by one by microcomputer automatic control and stop the part drive motor because of the passenger flow volume minimizing, be beneficial to energy-conservation.

Compared with prior art, the invention has the beneficial effects as follows: escalator manufacturing cost and operation energy consumption reduce greatly, and freight volume doubles; The ladder body is thin, the drive wheel radius is little, save space, and can two to more interlayers operations of the interior positive return of a ladder.The combination of each several part, the visual particular case adjustment of ladder type kind, comformability is very strong.

Embodiment

Present embodiment escalator such as Fig. 1-shown in Figure 24, the same with existing escalator, have truss 9, have dull and stereotyped rank or step spare; Handrail guardrail 8 with Armrest band 10.Ladder access is the trace step above the definition, below ladder access be the backhaul step, under the drive of the closed dull and stereotyped rank tow chain of a pair of, the running that moves in circles of trace step and backhaul step.In the vertical direction of the present invention moved trace step (top ladder access 2) wide and backhaul step (following ladder access 3) between distance, make the manned operation of people of all can standing simultaneously on the positive return step.All positive return steps of each escalator all overlap between each floor Horizon 1, form the continuous ladder access of closed cycle shape.

Fig. 1 middle plateform rank chain drive wheel 21 and dull and stereotyped rank chain flower wheel 26 be layout according to actual needs.Fig. 2 is shown in Figure 3 by dynamic host 40 outputting powers; Successively through dynamic host driving wheel 41; Dynamic host messenger chain 43 drives dynamic host flower wheel 42, and then drives dull and stereotyped rank chain drive wheel 21; Reach dull and stereotyped rank tow chain 20, drive dull and stereotyped rank and do running forward or backwards along the dull and stereotyped rank chain chain rail in the truss 9 28.Handrail drive wheel 11, the 12 also stressed runnings coaxial with dull and stereotyped rank chain drive wheel 21 or dull and stereotyped rank chain flower wheel 26 drive the handrail 10 and the run-in synchronism in the same way of dull and stereotyped rank of both sides.

In Fig. 1, dynamic host 40, dull and stereotyped rank chain drive wheel 21 is located at floor bottom (the figure lower left corner).Dull and stereotyped rank as shown in Figure 4 chain flower wheel 26 is located at floor top (Fig. 1 upper right corner).Step 2 is up passenger above supposing, then descending passenger relies on down the descending following ladder access 3 of Stairs 5 (as shown in Figure 5) arrival when just ascending stair.The positive return ladder access connects with the non-manned vertical ladder access 6 of interlayer at each floor gap.

Like Fig. 6; When many ladder interlocks and escalator when delivering at full capacity; It is not enough only relying on the forward drive of the dull and stereotyped rank of two driving host, the 40 drives chain drive wheel 21 of every ladder, and promptly need automatic breakdown another driving host 40 midway this moment, drives dull and stereotyped rank chain reverse drive wheel 7 and give power-assisted (Fig. 1; Figure 28, Figure 29).

What Fig. 7, Fig. 8 illustrated respectively is dull and stereotyped rank 23 and the lateral plan that the dull and stereotyped rank 22 of limited slip block are installed, and shows bottom surface, dull and stereotyped rank and positive broach bar 29.Fig. 9 is dull and stereotyped rank tow chain 20, dull and stereotyped rank BOGEY WHEEL 24, dull and stereotyped rank 23, the birds-eye view of dull and stereotyped rank 22 of limited slip block and limited slip block 30 mutual structures is arranged, and shows skirtboard 39.Every dull and stereotyped rank are near the both sides of growing the limit, and gear ring 44 is meshed on the dull and stereotyped rank that all distributing, and dull and stereotyped rank load-bearing axis 25 is in positive circular hole 45 of load-bearing axis and load-bearing axis elliptical aperture 46.Dull and stereotyped rank BOGEY WHEEL 24 is equipped with in the both sides of load-bearing axis, and two terminations of load-bearing axis 25 are installed in the chain plate hole of dull and stereotyped rank tow chain 20.The sprocket wheel of dull and stereotyped rank BOGEY WHEEL 24 and dull and stereotyped rank tow chain 20 is supported with dull and stereotyped rank chain chain rail 28 by dull and stereotyped rank wheel wheel track 27 respectively.Suppose: the thickness on every dull and stereotyped rank is about 4 centimetres, and its bottom surface and front all are uniform-distribution with dull and stereotyped rank broach bar 29.The maximum distance of shaft centers of two adjacent dull and stereotyped rank load-bearing axises 25 is 21 centimetres (as shown in Figure 7), and then the developed width on every dull and stereotyped rank equals 21 centimetres and adds upper flat plate rank thickness, promptly 25 centimetres.In this escalator, not depend dull and stereotyped rank tow chain 20 alone and drive dull and stereotyped rank, dull and stereotyped rank engagement gear ring 44 also can be through being enclosed within on the dull and stereotyped rank load-bearing axis 25 each other, the transmitting portions tractive force, and prevent dull and stereotyped rank mutual dislocation.

To be two kinds of dull and

stereotyped rank

22,23 took turns 7 o'clock through dull and stereotyped rank chain drive wheels 21 or dull and stereotyped rank chain flower wheel 26 or dull and stereotyped rank chain reverse drive Figure 10 because the factor of bend, make dull and stereotyped rank load-bearing axis 25 in load-bearing axis elliptical aperture 46 before and after little scheme drawing that moves.Suppose: the dull and stereotyped rank chain distance of shaft centers of chain rivet in twos is 7 centimetres, and the number of teeth of dull and stereotyped rank chain drive wheel 21, dull and stereotyped rank chain flower wheel 26 and dull and stereotyped rank chain reverse drive wheel 7 is 18 teeth, and then the radius R of three sprocket wheels is 20.05 centimetres.

Shown in Figure 11, Figure 12 is that the mutual engagement gear ring 44 on two kinds of dull and

stereotyped rank

22,23 is enclosed within the dull and stereotyped rank load-bearing axis mutual engagement in 25 last times.Every dull and stereotyped rank are near the both sides of growing the limit, and what comprise in the gear ring of dull and stereotyped rank engagement gear ring 44, one sides that all distributing is load-bearing axis elliptical aperture 46, and what comprise in the gear ring of opposite side is the positive circular hole 45 of load-bearing axis.When the bend of dull and stereotyped rank chain drive wheel 21 or dull and stereotyped rank chain flower wheel 26 or dull and stereotyped rank chain reverse drive wheel 7 is passed through on dull and stereotyped rank; Be enclosed within the load-bearing axis 25 in the positive circular hole 45 of one flat plate rank load-bearing axis; Can pass through above-mentioned sprocket wheel bend swimmingly to guarantee dull and stereotyped rank 46 li little moving in front and back of load-bearing axis elliptical aperture on adjacent dull and stereotyped rank.

Figure 13-Figure 15 is equipped with the dull and stereotyped rank 22 of limited slip block and the relative position figure of limited slip block 30.

Figure 16 illustrate limited slip block 30 when coming in and going out 4 mouthfuls of fishbacks along rail 37 on the limited slip block wheel, the state of rail 36 lifting moving down.The limited slip block wheel is gone up rail 37 and between discrepancy fishback 4 oral regions, is just had about 1 meter long.Limited slip block wheel rail 36 down has (not manned step district does not have) in whole manned step interval.It is that limited slip block wheel 31 is led the effect of falling that the limited slip block wheel is gone up rail 37.And limited slip block wheel down rail 36 except that district before and after 4 mouthfuls of the fishbacks of coming in and going out leads limited slip block wheel 31 rise lead fall, also the limited slip block 30 after whole manned step district is supporting limited slip block wheel 31 and rising makes its unlikely falling.Do not have limited slip block on the structure-steel framing of dull and stereotyped rank two broadsides, each is wide about 2 centimetres, and the length of limited slip block 30 slightly is shorter than the length on dull and stereotyped rank 23.Suppose: limited slip block 30 is except that " T " prefix at two ends, and is all wide 1 centimetre, high 7 centimetres.Both sides have 4 limited slip block wheels 31 up and down.Dull and stereotyped rank and all two-sided use of limited slip block.The limited slip block spacing screw rod 34 that goes up and down is arranged on the mid point of the two ends of limited slip block 30 " T " font; Screw rod penetrates from the structure-steel framing lateral inside spin that the dull and stereotyped rank of limited slip block 22 broadside mid points are arranged; And move up and down for 35 li at spacing screw rod shifting chute; Can not come off when limited slip block 30 is gone up and down in dull and stereotyped rank, and limited slip block exceed the height of dull and stereotyped terrace after rising can be by spacing screw rod shifting chute 35 restrictions, generally be controlled at and exceed dull and stereotyped terrace 1-3 centimetre.Limited slip block wheel 31 leans on a removable limited slip block wheel shaft-cup 32 fixing, the wheel shaft-cup by two wheel shaft-cups fixedly Luo silk 33 Luo connect fixing.Limited slip block 30 top and bottom have and dull and stereotyped rank broach bar 29 cooresponding limited slip block broach bars 38.

Handrail 10 in the arbitrary ladder of escalator twice rotation lip towards: promptly earlier up with downward lip Rotate 180 degree; Behind trace ladder access 2 or backhaul ladder access 3 handrails; With downward (reinstatement) handrail once more of the lip Rotate 180 degree that makes progress, make its unlikely waste again.In Fig. 1, handrail rotation lip turns to the interval long more, the difficult more volume damage of handrail towards about 2 meters of interval 15 length (or look actual needs and decide).

Figure 17 to Figure 19 promptly is that both sides handrail 10 rotates lip towards interval 15 o'clock in process, under the control of top guide wheel 16 groups, makes the cutaway view that 180 degree reverse at the rotation lip.To be handrail 10 lead the lateral plan when reversing in guide wheel 16 tops towards the top being rotated lip to Figure 20, also is the lateral plan of Figure 19.Handrail 10 is in the rotation lip that different angles become helical trajectory and equidistance by array leads on guide wheel 16 tops towards the top, in moving progressively rotation change lip towards.Top guide wheel axle bed 17 Luo are connected on the top wheel stand set collar 18; And set collar Luo is then on two set collar supports 19 up and down.Concrete steering procedure is following: the handrail 10 that (like Fig. 1) gets off through backhaul (below ladder access 3) gets into the rotation lips after interval 15, and the lip of this moment down.Figure 17 illustrates handrail 10 and is in the rotation lip that different angles become helical trajectory and equidistance by array and leads on guide wheel 16 tops towards the top, and Figure 17 to Figure 19 has accomplished by lip and rotated to lip 180 degree up down.Again through lip inwardly handrail drive wheel 11 (like Fig. 2, Figure 21) continue up, through lip outwardly handrail hold guide wheel 14 (Figure 23) and lip inwardly handrail hold the handrail state of guide wheel 13 (Figure 24) entering trace (above ladder access 2).(see figure 1) gets into towards interval 15 places at top-right rotation lip and to rotate lip towards process for the second time after trace (above ladder access 2) handrail finishes.The lip rotary course is with aforementioned identical.With downward lip Rotate 180 degree up after, by lip handrail drive wheel 12 (seeing Figure 22) outwardly, send into cyclic process next time.

Calculating is measured on single ladder access and dull and stereotyped rank to present embodiment, and the terraced body thickness of escalator is with very big attenuation.Truss 9 is can be controlled within 15-20 centimetre to following gross thickness by the top.The diameter of drive wheel is about 40 centimetres.

The mounting means in the foregoing description, also can adopt the mounting means shown in Figure 25-Figure 31 etc., can carry out the ladder type combination during use according to actual needs and arrange interlock.For example: the ladder type mounting means among Figure 25 and Figure 27 is two ladder interlocks, and an available cover control system is controlled a driving host and driven; Ladder type mounting means among Fig. 1, Figure 26, Figure 30 and Figure 31 is four ladder interlocks, and an available cover control system is controlled two driving host and driven; Ladder type mounting means among Figure 28 and Figure 29 is six ladder interlocks, and an available cover control system is controlled three driving host and driven.The ladder types of many ladder interlocks can also be according to the ridership size, and self-opening or stop the part driving host in good time is so that energy-conservation.And can be through reinforcing dull and stereotyped rank tow chain, or strengthen driving host power, or increase midway that driving host makes more ladder accesses participate in interlock.

In the multiple ladder type shown in the present invention, except that minority as known escalator from the upper and lower passenger in front, the overwhelming majority can change the upper and lower passenger of both sides mouth from staircase into.And the part escalator upper and lower passenger of floor is halfway arranged.Ladder type mounting means shown in Figure 26, Figure 27, Figure 29-31 can not use Stairs 5.
