The specific embodiment
Fig. 1 schematically illustrates passenger conveyor system 20, and it is escalator in this example.Yet the present invention is not limited to escalator, but applicable to the passenger conveyors of other type, for example moving sidewalk.Shown in passenger conveyor system 20 comprise can be along a plurality of steps 22 of circulatory motion, so step 22 can transport the passenger between platform 24 and 26.
Truss structure 28 supports the parts of escalator system in known manner.In one example, truss structure 28 mainly is formed from steel, and can adapt to step 22 along having the motion that the passenger transports side (illustrating) and returns the path of side (not shown).As is known, step loop return that side is hidden in truss usually or in other structure of conveyor system components.
Step chain is associated with step 22 and moves along ring 30.Step chain comprises a plurality of step chain 32.Step chain is supported by the suitable part of truss structure 28, makes it to move along chain ring 30 in a known way.
Driver module 40 promotes step chain and step 22 as required, so that the passenger is moved between platform 24 and 26.Driver module 40 comprises electrical motor 42, and it can make drive wheel 44 rotate with required speed.The motion of drive wheel 44 causes Transmission 46 motions, and Transmission 46 engages with step chain, to be used to that step 22 is moved as required.Idle pulley 48 has supported the opposite end of Transmission 46.In one example, Transmission 46 is a driving chain.In a preferred embodiment (being schematically shown as Figure 1A), Transmission 46 is served as reasons and is embedded in the made belt of many carrying cables 47 in the urethane material 49.Transmission 46 preferably has the outside face that is configured to provide in shape with the suitable non-slip engagement of step chain.The those skilled in the art who has understanded this specification sheets advantage can select or design Transmission to satisfy the needs of its particular condition.
Can understand best from Fig. 2, step chain loop 30 comprises corresponding to first side 50 of the passenger side of step loop with corresponding to second side 52 of returning side of step loop.Some selected parts that in Fig. 2, only schematically shown escalator system 20.This exemplary means comprises the first driver module 40A and the second driver module 40B, and they all can be provided for power that step chain is moved along chain ring 30.Driver module 40A only engages with step chain on first side 50 of step chain loop 30.Driver module 40B all engages with the both sides 50 and 52 of step chain loop 30.Only has driver module with a side engagement of step chain loop 30 and is important difference with conventional apparatus.Module 40A can only engage with step chain loop 30 on second side 52, but can increase the load at driver module 40B place on the belt like this.
By device of the present invention, the interval between the driver module needn't strictly or accurately be controlled as desired in the conventional apparatus.Part shown in the step chain 54 and 56 will can not stand the variation (because of change in location, wearing and tearing or the het expansion of driver module causes) of thrust or tensile force, and this is because driver module 40A only is applied to power F1 on first side 50 of step chain loop 30.The invention provides such advantage, i.e. the interval between the control and driving module accurately, but can allow driver module is placed in the escalator system boundary aspect bigger degree of freedom and changeability.
In having the conventional apparatus of a plurality of driver modules, the weight that each module supported is uncertain.The power relevant with each driver module has been introduced than the more variable that can separate (based on known relation), therefore can't accurately determine the power at each module place, and requires more complicated adjustment program.
By contrast, device of the present invention provides statically determinate system, and it is insensitive to the interval between the driver module.Device of the present invention provides available five systems that equation is described that have five variablees.Therefore, device of the present invention is to have similar number variable and equation fixed system really, and it can be separated.Guide around the revolution place guide rail (not shown) of step to be preferably designed to not carry any, therefore can adopt following equation than heavy load.Except by carrying out power transmits with driver module that both sides all contact, this design has avoided passenger and step chain to return any power transmission between the side.
For example, on first side 50 (being passenger side) of the step chain loop 30 in example shown in Figure 2, the belt 46A of driver module 40A has applied power F

By device of the present invention, only be applied to load on the step chain and equal motor torque divided by effective wheel radius with the module of a side engagement of chain ring 30.This load can utilize the known relation between motor torque and the chain movement speed to determine.
In an exemplary means, the driver module that all engages with step chain loop 30 both sides comprises less electrical motor, so that balance is passed to the power on the passenger side of each module from driver module.Apply the passenger side of motor torque with the driver module (being 40B) that step chain loop 30 both sides all engage, and will encircle 30 the weight transmitting of returning side to passenger side (i.e. first side 50) to step chain.Therefore, in this example, the smaller motor of the driver module that all engages with both sides allows to distribute equably in the power that each driver module place imposes on the passenger side of step chain loop.
Another advantage of the present invention is, can use different materials to make step chain 32.For example, aluminium is because of its lightweight and Corrosion Protection but a kind of material that meets the requirements.By device of the present invention, link material (being aluminium) can not cause conflict with different expansion rates between truss or the guide material (being steel).
Although do not illustrate specially, yet in another exemplary means, driver module 40A has identical size with 40B, and the step chain loop path deviation is opened a side of one of them driver module, makes driver module only engage with first side 50 of step chain loop 30.The those skilled in the art who has understanded this specification sheets advantage can expect realizing the effective means at the required interval between driver module and the step chain, make driver module only with a side engagement of step chain so that satisfy the needs of its particular condition.
Fig. 3 has shown another exemplary means, and wherein driver module 40A all engages with the both sides 50 and 52 of step chain loop 30, and driver module 40B only engages with first side 50 of step chain loop 30.Can change the layout of driver module according to the needs of particular condition.
Fig. 4 has shown another exemplary embodiment of the present invention.In this example, driver module 40A and 40B all only engage with first side 50 of step chain loop 30.Synchronization module 60 comprises synchronous piece 62, and it all engages with the both sides 50 and 52 of step chain loop 30.Synchronization module comprises the wheel 64 and 66 that can rotate freely, and it has supported synchronous piece 62 so that correctly engage with step chain 30.Synchronization module 60 is passed to first side with power from second side, but increases any power for the step chain system.This device allows to use less driver module, because these modules needn't all engage with the both sides of chain ring.In device for example shown in Figure 4, can adopt any amount of driver module.
In one example, synchronization module 60 comprises the synchronous piece 62 corresponding to Transmission 46A and 46B (promptly being coated with the belt of urethane).Synchronous piece 62 preferably has certain outside face, and it is configured to provide in shape with the suitable of step chain and engages.The those skilled in the art who has understanded this specification sheets advantage can select or design this synchronous piece, to satisfy the needs of its particular condition.
Fig. 5 has shown another exemplary embodiment of the present invention.In this example, a driver module 40 makes step chain loop 30 motions by only engaging with first side 50 of step chain.Synchronization module 60 ' comprise synchronous piece 62, it all engages with the both sides 50 and 52 of step chain loop 30.In this example, a plurality ofly take turns 64,66,68 and 70 and supported synchronous piece 62, make and to realize engaging with the suitable of step chain.Wheel 64-70 can be supported by truss structure in a conventional manner, makes them can allow synchronous piece 62 to move in response to the motion of step chain 30, thereby power is passed to first side and need not to increase any power to the step chain system from second side.
