Definitions

  • the invention relates to an escalator with variable travel speeds, the treads together with articulated elements form an endless step belt running on rollers, which is deflected at the upper and lower ends of the escalator and driven by a drive unit provided with drivers.
  • the major disadvantage of this escalator is that the passenger must enter and exit the escalator at a high step belt speed, while the travel speed in the inclined walking area is reduced after the steps are formed. With comparatively the same starting speed, the passenger therefore needs a longer travel time in such an escalator than in a conventional escalator. The greater the delivery head, the greater the time lost for the passenger. In the return area that cannot be entered, the step belt speed is the same as for the inlets and outlets.
  • the invention has for its object to propose an escalator in which the journey time for the passengers is reduced at a constant approach speed and in which the total number of steps is reduced compared to a conventional escalator and the risk of injury to passengers who may fall is reduced.
  • the advantages achieved by the invention are essentially to be seen in the fact that the travel time for the individual passenger, especially in the case of high-lift escalators, for example in subway stations, is markedly reduced, that the total number of steps can be reduced by up to 40%, which results in a reduction in the manufacturing price and that the risk of injury for passengers who may fall on the escalator is greatly reduced by the round front edge of the step.
  • Further advantages of the invention are that no step chains On the two outer sides of the steps, it is necessary that no deflection shaft is required at the bottom and no drive shaft is required at the top, and that a precise lateral guidance of the step belt is guaranteed by the self-contained and profiled inner raceway and the associated, inevitably guided rollers.
  • each step 1 has a support body 2, a step level 3 and a front part 4.
  • Two roller axes 5, 6 are fixedly arranged on a connecting carrier 2.1 of the supporting body 2.
  • Guide rollers 7 running on ball bearings are attached to the two ends of the longer roller axis 5 and guide rollers 8 running on ball bearings are also attached to the two ends of the shorter roller axis 6.
  • the guide rollers 7 run in the guide track 9 while the guide rollers 8 move on the guide rail 10.
  • the individual stages are connected to one another by articulated rods 13, ball bearings (16) mounted on the roller axis 5, 6 forming the pivot bearings of the articulated rod 13.
  • Step 1 is assembled from several parts in the exemplary embodiment shown.
  • a step plane 3 grooved in the direction of travel and a front part 4 which has a convex curvature and is also grooved in the direction of travel are firmly constructed.
  • two continuous roller axes, a longer roller axis 5 and a shorter roller axis 6 are firmly connected, the roller axes being accommodated on both sides of the step in a recess of a connecting carrier 2.1 of the support body 2.
  • rollers 7, 8 are mounted on ball bearings.
  • roller shaft 6 At the end of the roller shaft 6 there is additionally a pivotally mounted support 12 which carries two counter pressure rollers 11 which cooperate with the roller 8. Also on the roller axles 5, 6, articulated rods 13 are supported on ball bearings 16, with which each step 1 is connected to an adjacent step 1 and is thus joined to form the endless step belt.
  • the rollers 7 provided on the longer roller axes 5 are guided in the endlessly closed outer guide track 9, which has a U-shaped cross section, while the rollers 8 provided on the shorter roller axes 6 run on the likewise endlessly closed inner guide rail 10.
  • the U-shaped exterior Guide track 9 engages around the roller 7 and prevents this roller from lifting off.
  • the inner guide rail 10 has an upper running surface 10.1, a lower running surface 10.2 and a fastening flange 10.3.
  • the roller 8 is always held on the upper running surface 10.1 by the counter pressure roller running on the lower running surface 10.2 of the guide rail 10. Since the lower running surface 10.2 of the guide rail 10 can have a guide profile and the running surface 11.1 of the counter-pressure roller 11 can have a matching counter-profile, it is possible to precisely guide the steps 1 with the counter-pressure rollers 11 laterally.
  • the U-shaped outer guideway 9 is fastened with a fastening flange 9.1 to a supporting structure 15 of the supporting structure of the escalator.
  • the guide rail 10 is flanged to the same supporting structure 15 with its fastening flange 10.3. The mutual distances between the two guideways 9, 10 change during an entire revolution, but do not overlap.
  • the tread levels 3 of the treads 1 always assume a horizontal position in the accessible lead, on the other hand this results in higher and lower driving speeds for the step belt.
  • the movable step belt is covered on both sides by a vertically arranged, fixed base plate 14 that adjoins lateral balustrades.
  • the type of escalator described above works as follows:
  • the endless step belt is driven by a drive unit, not shown, in the upper part of the inclined running area between the step belt.
  • the drive unit can, for example, have a chain-like drive element which acts on one of the roller axles of individual steps and which advantageously simultaneously drives the forward run and the return run of the step belt.
  • Each individual step 1 of the step belt which is endlessly closed by the articulated rods 13 is guided by four rollers 7, 8 in four likewise endlessly closed guideways 9, 10.
  • rollers 7 arranged on the longer roller axles 5 of the step 1 run in the two outer guide tracks 9, which have a U-shaped cross section, while the rollers 8 arranged on the shorter roller axles 6 run on the upper guide tracks 10.1 of the inner guide rails 10 and from the counter pressure rollers 11 running on the lower guideways 10.2 of the inner guide rails 10 are held on their guideways.
  • the inner and outer guideways 9, 10 are spaced apart from one another over an entire revolution so that the step level 3 of each step 1 is in a horizontal position in the accessible lead.
  • the two guideways run at a correspondingly large distance from one another, so that steps 1 and fold the articulated rods 13 against each other, the treads 1 pushing together and forming a continuous horizontal tread plane over approximately three treads 1.
  • the distance between the two guideways 9, 10 gradually decreases in order to have the smallest distance in the inclined running area.
  • the treads pushed together in the horizontal running area are pulled apart again and assume an almost extended position together with the articulated rods 13 in the inclined running area.
  • the drive unit provided in the upper part of the inclined running area of the step belt is thus used in the area of high driving speed. Since the sloping forward and the sloping return have the same driving speed, the drive unit can also intervene in both runs at the same time.
  • a precise lateral step guidance is achieved in that the lower running surface 10.2 of the guide rail 10 has, for example, a triangular profile, on whose obtuse apex angle the counter pressure rollers connected to the steps are guided and centered.
  • the step band of the escalator according to the invention differs in some points from a conventional escalator.
  • the individual steps are not articulated on two endless step chains arranged on both sides of the step belt, which serve as a pulling element, but are directly connected to one another by articulated rods.
  • a positively guided folding movement occurs between the steps and the articulated rods through constant guidance of the rollers in the two endlessly closed guideways.
  • the step body is designed in such a way that the distance between two adjacent steps, which is increased by the connecting articulated rods, is bridged by a convex rounding of the step front part.
  • the continuous, closed track system for the rollers of the step belt also occurs here.
  • a drive unit arranged at the upper deflection point at least one drive unit provided in the inclined step band area between the step band occurs.
