Definitions
- the invention relates to an escalator or moving walk consisting of a truss, a step belt with steps or pallet belt with pallets for the transport of Persons and / or objects and one by means of a Balustrade base held balustrade with handrail, where a handrail drive drives the handrail.
- a disadvantage of the known device is that the drive of the handrail on the inside of the handrail by means of a drive belt. If the belt tension subsides, the drive of the handrail is lacking Friction on the free-running wheel is no longer guaranteed. In addition, there is a large loop on the wheels and large bending changes on the handrail necessary, which is negative affects the lifespan of the handrail.
- the invention seeks to remedy this.
- the invention as characterized in claim 1 solves the problem to avoid the disadvantages of the known device and to create a handrail drive that is the handrail of a Drive escalator or moving walk gently.
- the advantages achieved by the invention are in essential to see that with the handrail drive according to the invention and with the handrail guide according to the invention a much shorter Handrail length is possible.
- the handrail crosses that Step belt or the pallet belt is not, which is an advantage has that the truss can be made narrower.
- the Handrail drive according to the invention drives the handrail on the outside, the bigger one Has coefficient of friction, which causes greater frictional forces can be implemented with fewer handrail bending changes.
- the handrail drive according to the invention mechanically simpler and with fewer individual parts built up, which in turn has the advantage of shorter assembly times and less maintenance and smaller Has manufacturing costs.
- Fig. 1 shows an escalator 1 with one side existing balustrade 1.1 with handrail 2, the Balustrade 1.1 held by a balustrade base 1.2 becomes.
- a step belt 1.3 that transports people Stages 1.4 are connected to the side of the balustrade base 1.2 on.
- a handrail drive 2.1 drives the handrail 2, whereby a friction wheel 3 the handrail 2 on the outside 2.2 or Hand side frictionally drives.
- On the inside 2.3 or sliding position of the handrail 2 press rollers 8 den Handrail 2 to the friction wheel 3.
- One on a step sprocket 5 arranged drive wheel 4 drives the friction wheel 3 friction or form-fitting.
- the step sprocket 5 moves one Step chain 5.1, on which the steps 1.4 are arranged.
- a main shaft 6 carrying the step sprockets 5 becomes driven by a drive sprocket 7, which Drive sprocket 7 by means of a not shown Dart stair drive (chain drive and escalator motor) is drivable.
- the friction wheel pressed against the driving wheel 4 by means of spring 16 3 drives the handrail 2 by friction on the outside 2.2 on.
- the friction wheel 3 has a diameter, for example of about 750 mm.
- On the inside 2.3 or on the Sliding position of the handrail 2 press the pressure rollers 8 Handrail 2 against the friction wheel 3.
- the coefficient of friction on the Inside 2.3 is much lower than the coefficient of friction on the outside 2.2 of the handrail 2
- the friction wheel 3 on one escalator side is for Torque transmission by means of a shaft 9 with the friction wheel 3.1 connected to the other escalator side, where Pressure rollers 8 the handrail 2 against the friction wheel 3.1 to press.
- On an escalator with an inside The friction wheel 3.1 can also be driven by an escalator additional driving wheel are driven.
- the shaft 9 is in the side plate 11 by means of Bearing 10 stored.
- Fig. 7 shows the handrail drive 2.1 with independent friction wheels driven by one another 3.3.1.
- the friction wheel 3 one side of the escalator is driven by the drive wheel 4 driven.
- the drive sprocket 7 is in this Design variant replaced by a toothed belt wheel 18 the toothed belt wheel 18 and the main shaft 6 by means of the toothed belt sprocket of the Escalator motor toothed belt 19 is driven.
- the friction wheel 3.1 of the other escalator side is by means of the spring 16 against the toothed belt back of the toothed belt 19th pressed and driven frictionally. This is a constant speed and no slippage given. To improve traction, the Toothed belt back must be provided with knobs.
- An advantage of this embodiment variant is that fewer individual parts (shaft 9, countershaft 13 omitted) are necessary. Without shafts there are shorter assembly times for the escalator drive and for the handrail drive possible.
- the handrail drive 2.1 according to the invention can also be used Moving walks are applied.
