The specific embodiment
Below, based on accompanying drawing an embodiment of the invention are described.
The middle accelerating type escalator of present embodiment as shown in Figure 1, possesses step roller track 1 and auxiliary guide rail 2, and this step roller track 1 and auxiliary guide rail 2 are installed in the using escalator mouth that is arranged at lower layer side and upper layer side and fall between the ladder way on the structure that is set up.These step roller tracks 1 and auxiliary guide rail 2 are laid on the intermediate, inclined portion of this centre accelerating type escalator obliquely with mutual closely parallel state, and at the using escalator mouth and fall near the ladder way, Yi Bian gently leave, Yi Bian pass to horizontality.
Moreover the middle accelerating type escalator of present embodiment possesses a plurality of steps 3 of bonded assembly annularly.On these steps 3, the mode with the front side of the moving direction shown in the arrow A that is arranged in Fig. 1 is equipped with front-wheel 4 with rotating freely respectively, and in the mode of the rear side that is positioned at moving direction trailing wheel 5 is installed with rotating freely.In addition, here, the situation of running is that example describes so that the middle accelerating type escalator of present embodiment rises, and under the situation that makes its running that descends, the moving direction of each step 3 then is a reversing sense.Therefore, under the situation of running that descends, say correctly that the front-wheel 4 of each step 3 becomes opposite with the position of trailing wheel 5 relation.But, in this manual, for feature of the present invention is described more understandablely, the moving direction A of each step 3 under the situation that above elevator is changeed is that benchmark is considered, the roller of front side that will be installed in the moving direction A of each step 3 for unified mark is called front-wheel 4, and the roller that is installed in the rear side of moving direction A is called trailing wheel 5.
A plurality of steps 3 are subjected to the propulsive effort of aftermentioned drive system, and the front-wheel 4 of each step 3 moves along step roller track 1, and the trailing wheel 5 of each step 3 moves along auxiliary guide rail 2, and thus, the attitude of keeping regulation is at the using escalator mouth and fall between the ladder way circulation and move.At this moment, in intermediate, inclined portion, each step 3 is keeping being arranged in step shape and mobile under the tread horizontal state, when when falling ladder way, variation corresponding to the relative position between step roller track 1 and the auxiliary guide rail 2, the diff-H that the step of adjacency is 3 correspondingly reduces, and is arranged in state on the horizontal surface each other thereby become falling the tread of ladder way place in abutting connection with step 3.And under this state, each step 3 enters the below of fishback 6 and arrives fold back portion, reverses along sprocket wheel 7 in fold back portion, and returns to the using escalator oral-lateral along the route of loop side.
The step chains 10 of mobile a plurality of steps 3 by as shown in Figure 2 that circulate like that as mentioned above is connected.Step chains 10 is made of a plurality of pin rolls 11 that uniformly-spaced are provided with and chain link 12a, the 12b (with reference to Fig. 3) that connect these pin rolls 11 and form the funicular entity of one, in this example, shown in Fig. 3 is detailed, becoming two places of trisection point that pin roll 11 is installed respectively with the end of each chain link 12a, 12b.Constitute the chain link 12a of this step chains 10, be fixed on respectively on the step 3, hereinafter referred to as fixing chain link 12a at the front-wheel 4 of near fixed position, rear portion 13a the trailing wheel 5 of step 3 and step 3 and the 13b place, pars intermedia fixed position between the trailing wheel 5.Moreover, the chain link 12b of formation step chains 10, near the 13a place, fixed position, rear portion the trailing wheel 5 of the pars intermedia fixed position 13b and the step 3 of going ahead of the rest is installed on the step 3 with rotating freely respectively, hereinafter referred to as movable chain link 12b.
In being suitable for middle accelerating type escalator of the present invention, as mentioned above, constitute the fixedly chain link 12a of step chains 10, be fixed on fixed position, the rear portion 13a and pars intermedia fixed position 13b of each step 3, and, the movable chain link 12b of formation step chains 10, between adjacency step 3,3, be installed in pars intermedia fixed position 13b and 13a place, fixed position, rear portion with rotating freely, thus, a plurality of steps 3 connected by step chains 10 with ring-type.And, by by after the chain drive mechanism 20 that describes in detail drive step chains 10, thereby make with a plurality of steps 3 of ring-type bonded assembly, as mentioned above, at the using escalator mouth of this centre accelerating type escalator and to fall between the ladder way circulation mobile.
At this, if pay close attention to two steps 3,3 of adjacency, then owing to be located at fixed position, the rear portion 13a of step 3 in advance, and the pars intermedia fixed position 13b that is located at follow-up step 3, be installed in the both ends of a movable chain link 12b and be connected, therefore, can make the pars intermedia fixed position 13b of follow-up step 3, fixed position, rear portion 13a with the step 3 of going ahead of the rest is a fulcrum, and moves along the circular arc that is radius with movable chain link 12b.And, in being suitable for middle accelerating type escalator of the present invention, at the using escalator mouth and fall near the ladder way, move according to circular-arc track as described above by the pars intermedia fixed position 13b that makes each step 3, thereby reduce successively in abutting connection with the diff-H of 3 on step, and make and on horizontal surface, become state arranged side by side each other at using escalator mouth and the tread that falls the ladder way place in abutting connection with step 3.
Describe particularly, for example as shown in Figure 4, be configured under the coaxial situation at the trailing wheel 5 that makes fixed position, rear portion 13a and each step 3, fixed position, the rear portion 13a of each step 3 moves along auxiliary guide rail 2 with trailing wheel 5.That is to say that step 3 is during intermediate, inclined portion moves, fixed position, rear portion 13a and center fixed position 13b are listed as straight line, and pars intermedia fixed position 13b also moves along auxiliary guide rail 2 except that the 13a of fixed position, rear portion.On the other hand, get back to Fig. 3, if step 3 is near the using escalator mouths and fall near the ladder way, though then fixed position, rear portion 13a will continue to move along auxiliary guide rail 2, but pars intermedia fixed position 13b is lifted to the direction of leaving auxiliary guide rail 2 along above-mentioned circular-arc track, correspondingly, the diff-H in abutting connection with 3 on step reduces.
At this moment, because of the distance between the pars intermedia fixed position 13b of fixed position, the rear portion 13a of step 3 in advance and follow-up step 3, be by the length decision of the movable chain link 12b that connects them, so can not produce bigger change in abutting connection with the distance of 3,3 on step.In addition, if making riser (toe riser) 3a of each step 3 be configured as from the shape of laterally seeing is circular shape according to the motion track of pars intermedia fixed position 13b, then be lifted and the height and position of follow-up step 3 when changing as the pars intermedia fixed position of follow-up step 3 13b, the sport of this follow-up step 3 is carried out along the riser 3a of the step 3 of going ahead of the rest, can not make and 3 bigger gaps of generation of step of their adjacency, thereby make their position relation maintain best state.
In addition, pay close attention to connect the step chains 10 of each step 3, this step chains 10 is at the using escalator mouth and fall near the ladder way, and becoming to be lifted to the pars intermedia fixed position of the direction of leaving auxiliary guide rail 2 13b is the shape that the summit is bent into the mountain type.And step chains 10 is so crooked, then makes using escalator mouth and fall near the moving velocity of the step 3 the ladder way, and is slower than the moving velocity of the step 3 of intermediate, inclined portion.As a result, the moving velocity of the step 3 that intermediate, inclined is partly located than using escalator mouth and to fall near the moving velocity of the step 3 the ladder way fast, thereby has been realized quickening in the middle of so-called.
In addition, above-mentioned is the trailing wheel 5 that makes fixed position, rear portion 13a and each step 3 to be configured in coaxial situation be illustrated, if but fixed position, rear portion 13a be fixed on can be along on the position that auxiliary guide rail 2 moves, even then be not configured on coaxial passable with trailing wheel 5 yet.But, if adopt fixed position, rear portion 13a and trailing wheel 5 to be configured in coaxial structure, then can make trailing wheel 5 is installed in installation shaft on the step 3 and installation shaft that step chains 10 is installed on the step 3 is integrated by fixed position, rear portion 13a, like this, simplicity that can implementation structure.
In addition, in middle accelerating type escalator shown in Figure 3, the structure of step chains 10 is formed, length L 1 by making fixing chain link 12a is longer than the length L 2 of movable chain link 12b, even step chains 10 bendings are configured in the fixedly chain link 12a of the trisection point that forms step chains 10 and the pin roll 11 on the movable chain link 12b respectively and also can collide each other.In addition, in order to make the simple structure of step chains, can make the length L 2 of the length L 1 of fixing chain link 12a and movable chain link 12b approximately equal etc., and can be not limited to this ratio ground realization.
Moreover, in this implementation method, by making the fixed position of the relative step 3 of pars intermedia fixed position 13b, become the straight line arranged from pin roll 11 and fixed position, the rear portion 13a position after the tread lateral deviation is moved the offset delta amount of regulation, thereby make using escalator mouth and the moving velocity that falls near the step 3 the ladder way further reduce.
By making the fixed position of the relative step 3 of pars intermedia fixed position 13b, become the position after the straight line skew offset delta amount that pin roll 11 and fixed position, rear portion 13a are arranged, thereby make that step chains 10 is further extended when when intermediate, inclined portion place's chain link 12 is applied in tension force.But movable chain link 12b is connected to the axle 4a (limiting part) of front-wheel 4, and this 4a can not make step chains 10 be elongated to more than the angle of bend of regulation as killer.
In the middle accelerating type escalator of present embodiment, the chain drive mechanism 20 as driving step chains 10 adopts following structure, for example as shown in Figure 2, with pin roll 11 engagements of the shape that is arranged in a straight line at intermediate, inclined portion place, and transmits thrust to it.Below, this chain drive mechanism 20 is carried out specific description.
This chain drive mechanism 20 is positioned at intermediate, inclined portion, and possesses the rotating driving devices such as electro-motor 21 that are installed on the structure, is connected with eccentric crankshaft 22 on this rotating driving device 21.Eccentric crankshaft 22 has and is fixed on respect to axis locational four eccentric disks of 90 ° of phase places ground accentric that stagger mutually, and when driven in rotation actuating device 21, these four eccentric disks are that the center is carried out off-centre and rotated with the axis.
On four eccentric disks of eccentric crankshaft 22, make the off-centre rotation that is accompanied by eccentric disk and four pieces of swing plates 23 carrying out swing movement overlap on thickness direction, and connecting respectively.
Moreover these four pieces of swing plates 23 are except that the eccentric disk of eccentric crankshaft 22, also be connected with the eccentric disk of driven shaft 24, thereby when the eccentric disk of eccentric crankshaft 22 carries out the off-centre rotation, on one side can keep the state of the 90 ° of phase places that stagger respectively, Yi Bian stably carry out swing movement.
On the upper end and bottom of these four pieces of swing plates 23, be respectively arranged with turning gear 25 with pin roll 11 ingear trochoidal curves (the ト ロ コ イ De) shape of step chains 10.Moreover, in Fig. 2, for the part among the turning gear 25 of more easily understanding the structure of chain drive configuration 20, only illustrate the upper end that is arranged at four pieces of swing plates 23 respectively and bottom.
In the chain drive mechanism 20 that constitutes as described above, when driven in rotation actuating device 21, four eccentric disks of eccentric crankshaft 22 are subjected to the propulsive effort of this rotating driving device 21 and carry out the off-centre rotation respectively.And, be accompanied by the off-centre rotation of eccentric disk, Yi Bian four pieces of swing plates 23 are kept the state of the 90 ° of phase places that stagger mutually, Yi Bian carry out swing movement respectively.As a result, be arranged on the turning gear 25 of the trochoidal curve shape on each swing plate 23 and the pin roll 11 of step chains 10 and mesh in turn, thereby thrust is passed to pin roll 11, and drive step chains 10.
In the middle accelerating type escalator of present embodiment, as mentioned above, transmit the chain drive mechanism 20 of thrust by adopting to it with pin roll 11 engagements of the shape that is arranged in a straight line at intermediate, inclined portion place, thereby can make step chains 10 at the using escalator mouth and fall near the ladder way crookedly energetically, and quicken in the middle of can realizing more efficiently.Moreover, because the chain drive mechanism 20 of said structure has function as velocity limiter from principle,, can make the moment of torsion that transmits by eccentric crankshaft 22 less so rotating driving device 21 does not need velocity limiter.Thus, can realize the miniaturization of chain drive mechanism 20 overall dimensions, and can be configured in narrow and small the setting in the space, thereby can drive step chains 10 reliably.
Moreover, more than, the upper end of the swing plate 23 that shakes to rotate and the turning gear 25 that the bottom is provided with the trochoidal curve shape in the off-centre of the eccentric disk that is accompanied by eccentric crankshaft 22, and this turning gear 25 and the chain drive mechanism 20 of the roller pin 11 ingear structures of step chains 10 are illustrated for example, but replace such chain drive mechanism 20, for example as shown in Figure 5, also can adopt the chain drive mechanism 30 of following structure, between swing plate 23 and step chains 10, set the swing movement of following swing plate 23 and the circulation funicular entity 31 (thrust transferring elements) that carries out circulating motion, make the external tooth 32 of the outer circumferential side that is arranged on this circulation funicular entity 31 and pin roll 11 engagements of step chains 10.
In this chain drive mechanism 30 as shown in Figure 5, roller 33 is arranged on interior all sides of circulation funicular entity 31, by the turning gear 25 and these roller 33 engagements that is arranged on the trochoidal curve shape on each swing plate 23, thereby the swing movement of swing plate 23 is passed to circulation funicular entity 31, and make circulation funicular entity 31 carry out circulating motion along track 34.And, external tooth 32 by making the outer circumferential side that is arranged on this circulation funicular entity 31 and 11 engagements of the pin roll of step chains 10, the circulating motion of circulation funicular entity 31 is delivered to step chains 10, thereby drives step chains 10.
Moreover, in this chain drive mechanism 30, the turning gear 25 of the trochoidal curve shape that is arranged on the swing plate 23 and the roller 33 that is arranged on the circulation funicular entity 31 are disposed on the contrary.That is to say, as shown in Figure 6, also can roller 33 be set, and the turning gear 25 of trochoidal curve shape is set in interior all sides of circulation funicular entity 31 in the upper end and the bottom of swing plate 23.In addition, the chain drive mechanism 30 about structure with circulation funicular entity 31 as described above is documented on Japanese patent application 2001-373818 communique.
When the chain drive mechanism 30 that will use said structure drives step chains 10, outside the effect when having use chain drive mechanism 20 situations, also obtain following distinctive effect: can improve mechanical contact-ratio to step chains 10, make the motion stabilization of step chains 10, do not need to keep ingear back side supporting mechanism by the back side of pushing step chains 10, perhaps can realize the simplification of this structure, and can dwindle the radius that shakes of swing plate 23, thus the generation of vibration-inhibition and noise.
As described above, the middle accelerating type escalator of present embodiment with succinct structure, makes step 3 high-speed mobile at intermediate, inclined portion place, and at the using escalator mouth and near falling ladder way the moving velocity of step 3 is slowed down, and quickens in the middle of realizing.And, at the using escalator mouth and fall near the reduction that realizes the moving velocity of step 3 ladder way by the bending of step chains 10, at this moment, fixed position, rear portion 13a by the step 3 of will going ahead of the rest is connected by a movable chain link 12b with follow-up pars intermedia fixed position 13b, can guarantee the distance between them by the length of movable chain link 12b, therefore can not make in abutting connection with the distance of 3,3 on step and produce bigger change, thereby avoid in abutting connection with 3,3 gaps that generation is bigger of step or 3,3 problems of interfering mutually of step.
Moreover, the shape of the riser 3a of each step 3 of seeing from transverse direction is configured as, the circular shape that forms according to the motion track of pars intermedia fixed position 13b, thus, the differential motion of follow-up step 3 is carried out along the shape of the riser 3a of the step 3 of going ahead of the rest, thereby their position relation can be remained on optimum regime.
Next, at the 2nd embodiment of the present invention, describe with reference to Fig. 7 to Figure 10.Fig. 7 is the block diagram of summary of the middle accelerating type escalator of expression the 2nd embodiment, Fig. 8 is the amplification stereogram of wanting portion of the middle accelerating type escalator of the 2nd embodiment, and Fig. 9 is the enlarged side view of wanting portion of accelerating type escalator in the middle of the 2nd embodiment.
In addition, in the present embodiment, give identical symbol, do not carry out repeat specification the part identical or similar with the 1st embodiment.
As shown in Figure 7, the middle accelerating type escalator of present embodiment possesses a plurality of auxiliary steps 40 that are set to be positioned at 3,3 on two steps adjoining each other at a side of each step 3.These auxiliary steps 40 by Fig. 8 and Level Change shown in Figure 9 mechanism 41, can change corresponding to the variation of the difference of height of 3,3 on two steps and in abutting connection with the difference of height between the step 3.In addition, the bight 3b with auxiliary step 40 adjacency of step 3 forms curve form.
The length L 2 ' of this chain link 44a, 44b equates with the length L 2 (with reference to Fig. 3) of movable chain link 12b.Moreover, chain link 44a, the 44b angle with respect to the horizontal plane when auxiliary step 40 arrives the position of the tops, movable chain link 12b equates with the horizontal surface angulation when at utmost crooked with step chains 10.Thus, at the using escalator mouth and fall the ladder way place, the tread that can make the tread of step 3 and auxiliary step 40 at grade.
Moreover the riser face 40a of auxiliary step 40 supports that by chain link 45a, 45b this chain link 45a, 45b can be installed on the 3c of support sector and chain link 44a of step 3 with rotating freely, and is that the summit becomes parallelogram with each pivot point p1 to p4.The prominent some B of riser face 40a, with fulcrum p4 apart from length L2 ', thereby be made into and chain link 44b between form parallelogram.Thus, moving up and down of the tread of the angle point B of riser face 40a and auxiliary step 40 carried out interlock.In addition, because riser face 40a is the center rotation with fulcrum p1, the riser face 40a of auxiliary step 40 and riser 3a are at grade.
The middle accelerating type escalator of present embodiment, as shown in Figure 7, near the using escalator mouth, when moving between adjacency step 3,3 when producing difference of height to intermediate, inclined portion from horizontal part because of each step 3, by Level Change mechanism 41, the tread of auxiliary step 40 is positioned at the only about half of position between the tread of two steps 3,3 of adjacency.Thus, step 3 and auxiliary step 40 are arranged in staggered on direct of travel, compare with the situation of having only step 3, and difference of height forms the stepped of half.
Therefore, a side of auxiliary step 40 is arranged, the passenger is easily walked and move.By such structure, even 2 times of ground quicken, it is identical with the situation of auxiliary step that the step and the difference of height of auxiliary step are maintained, for example can realize the so-called low speed boarding safely that divides with 20m/, and the middle accelerating type escalator of the high accelerating velocity that moves in intermediate, inclined portion of the high speed of dividing with 40m/.In addition,, therefore reduced the possibility that scratches passenger's clothes owing to make the bight 3b with the step 3 of auxiliary step 40 adjacency form curve form, can pain even run into ankle yet.
Moreover, falling near the ladder way, the difference of height that the step that adjoins each other is 3,3 gently reduces, and is aligned to on the one side, and at this moment, auxiliary step 40 also is aligned to on the one side.
