Abstract
The power driving equipment for escalator or automatic pavement is characterized by that one end of main shaft is directly and coaxially connected with driving main machine, and said driving main machine is formed from miniaturized synchromotor, speed reducer and brake. Because said invention saves the driving device between driving main machine and main shaft, it not only can reduce upper machine room size and shorten the structure length of whole equipment, but also can reduce noise, simplify installation, raise running safety and save energy source.
Description
The present invention relates to a kind of Power Drive Unit that is applied on escalator or the moving sidewalk.
The structure of the Power Drive Unit of present most escalator or moving sidewalk is equipped with AC asynchronous motor 11, drg 13, retarder 12 as shown in Figure 1 in the machine room of top, link to each other by double bush roller chaiin between main shaft 2 and the retarder 12.Some other structure is also arranged,, place the structure in the terraced road, upper end as electrical motor is linked by reducing gearbox and main shaft middle part; The multistage drive configuration that conduction chain is replaced with tooth bar etc.All exist top machine room size big in the said structure, problems such as the scantling length size of whole escalator or moving sidewalk is big and the operation noise is big, and safety is relatively poor, and driving efficiency is low, and, make installation, maintenance, care work very difficult owing to complex structure, limited by the position.At present, international counterparts already also has a kind of imagination, and promptly the electrical motor of adorning a slow speed of revolution, big torque at spindle end comes the direct drive main shaft, and this structure belongs to " gearless machine " type that world's elevator is already generally acknowledged.As " gearless machine " type big torque, the slow speed motor that must adopt, its scantling of structure is huge, involve great expense, in addition the dynamo-electric brake of the big lock torque of design one cover in addition.Be difficult to minification with regard to this class formation of present technology, reduce cost, so this class imagination is not applied in the middle of reality.
The objective of the invention is a kind ofly can reduce top machine room size in order to provide, shorten the entire machine scantling length, can reduce noise again, improve safety in operation. save the energy and simplify installation, maintenance, the escalator of care work or the Power Drive Unit of moving sidewalk.
The present invention includes main shaft and be installed in step driving chain sprocket and handrail drive sprocket on the main shaft, the direct coaxial connection driving host of main shaft one end, this driving host is formed by synchronous motor, retarder, the drg combination of micro-miniaturisation, driving host is installed on the structure-steel framing by axle bed, and the main shaft other end is installed on the structure-steel framing by axle bed.
The present invention shifts out driving host from the machine room of top, combine with main shaft, makes coaxial integrative-structure, has reduced top machine room size, has also shortened the scantling length of entire machine.Because the present invention has cancelled the transmission link between main shaft and driving host, can reduce material consumption, reduce noise, improve safety reliability, retarder of the present invention can adopt built-in high precision helical teeth planetary reduction gear, freedom from repairs is grown, is close to life-span, move 15 years and can need not to maintain, designs simplification of the present invention also makes the installation, maintenance of entire machine, care work simplify greatly, improve driving efficiency simultaneously, saved a large amount of electric energy.Compare with aforementioned " gearless machine " type elevator, the invention belongs to typical case's " geared machine " type, because the present invention has retarder, make electrical motor, retarder, drg accomplish micro-miniaturisation, and be contained in the axle housing of main shaft, dwindle the complete machine size greatly, thereby, the present invention has very high economical and practical value, can directly apply to production practice.
Fig. 1 is the Power Drive Unit structural representation of existing escalator or moving sidewalk;
Fig. 2 is the structural representation of one embodiment of the invention;
Fig. 3 is that the A of Fig. 2 is to partial schematic diagram;
Fig. 4 is that the B of Fig. 2 is to partial schematic diagram;
Fig. 5 is the structural representation of another embodiment of the present invention.
Embodiment one:
As shown in Figure 2, the present invention includes main shaft 2 and be installed in step driving chain sprocket 3 and handrail drive sprocket 4 on the main shaft 2, the direct coaxial connection driving host 1 of main shaft 2 one ends, this driving host is made up of the permasyn morot of micro-miniaturisation, built-in helical teeth planetary reduction gear, drg, driving host 1 is installed on the staircase structure-steel framing 7 by self support, main shaft 2 other ends are affixed with extension minor axis 5, are installed on the staircase structure-steel framing 7 by axle bed 6 by extending minor axis 5.Such structure can be pulled down the extension minor axis when needed, loads onto the power of another driving host with the raising entire machine, and improves the commonality of part in the series of products.The synchronous motor of driving host and variable frequency convertor, position detector, control utmost point energizing circuit are formed the commutatorless motor speed regulation device, this speed regulation device is a kind of prior art, it has electrical efficiency height, characteristics that power factor is high, adopt this device can further improve efficient of the present invention, and this device has had the electric braking link, when receiving cutoff command, it can make electrical motor produce enough lock torques, guarantees that escalator or moving sidewalk can stop in the stop distance range of safety standard defined.Drg in the driving host directly links to each other with main shaft, meets the relevant safety and the technical requirements of " additional brake " in the national standard fully, makes the present invention also can satisfy the relevant regulations requirement of public traffic type escalator or moving sidewalk.Therefore, the present invention need not change structure and just both had been applicable to and coventional type escalator or moving sidewalk also was applicable to public traffic type escalator or moving sidewalk.
As shown in Figure 3, Figure 4, among the present invention, between axle bed 6 and the staircase structure-steel framing 7 about, be equipped with respectively on the fore-and-aft direction positioning screw 8,8 ', at left and right directions, positioning piece 9 ' is housed on the staircase structure-steel framing 7, positioning screw 9 is contained on the positioning piece 9 ' and against axle bed or main frame support, connects axle bed 6 and staircase structure-steel framing 7 or main frame support and staircase structure-steel framings 7 by bolt arrangement 10.Like this position between axle bed or main frame support and the staircase structure in the space three directions all can adjust, thereby improve setting accuracy, increase the stationarity of machine run.
Embodiment two:
Big the arriving to a certain degree of hoisting depth when escalator or moving sidewalk, during the under power of a driving host, can be as shown in Figure 5, outrigger shaft among the embodiment one 5, axle bed 6 are pulled down, change another driving host 1 ', be installed in by self support by driving host 1 ' and form the two-shipper drive configuration on the staircase structure-steel framing 7.Other structure is with embodiment one in the present embodiment.
