Definitions

  • the invention relates to a fastening device for the stages of an escalator equipped with two trailing rollers supported on a running rail, each on an endless transport chain arranged laterally next to the steps and supported by chain rollers on a guide rail, to form a chain comprising a forward and a return, each with horizontal and inclined Transition arches provided with existing endless step belt.
  • Such a fastening device for the steps of an escalator or a passenger conveyor belt has become known from DE-OS-2 342 849, in which the individual steps are fastened to a step axis connecting the two transport chains by means of clamping jaws.
  • These fastening devices are arranged on both sides of the step body and are made in two parts. They each consist of a fixed bearing half arranged on the step body and the clamping jaw which is pivotally connected to the step body and provided with an attachment. When inserting a step, the jaw automatically lays around the step axis using the attachment. In this position, the pivotable bearing half can be rigidly connected to the step body from the outside, for example by a screw.
  • step axes In order to dampen vibrations and noises, additional sleeves made of elastic material are provided between the step axes and the step fastening.
  • This fastening device for steps has the advantage that the removal and installation of individual steps for maintenance purposes can be carried out in the simplest way without additional preparation work.
  • a disadvantage of this step attachment which also adheres to most other known escalator designs, is that despite the damping elements used between the step axes and the step body, vibrations are transmitted from the raceways or from the transport chains to the step body and running noises occur. Such running noises are noticeably noticeable mainly in the case of compact steps, which are produced in a single piece by the press casting process, namely when the steps are bumped in an unloaded state over soiled tracks.
  • the invention has for its object to provide a fastening device for the steps of an escalator, in which the bumping of the steps is better damped and in which there is practically no bearing wear due to the relative movements between the step and the step transport means.
  • Another advantage of the invention is that the elastic joint is practically not subject to wear, since there is no bearing friction. This advantage is particularly important for open-air systems with a high degree of pollution, since neither moisture nor dirt strongly influences the elastic joint.
  • Step 1 of an escalator shown in FIG. 1 has a step surface 1.1, a front part 1.2 and two side plates 1.3. On the two side plates 1.3, a drag roller 2 and a fastening device are provided for connection to a transport chain 10 arranged on each side of the steps 1.
  • the connecting parts of the fastening device arranged in the body of stage 1 are additionally shown enlarged in FIG. 2.
  • These are an elastic joint 4 consisting of an outer body 4.1, an inner body 4.2 and a number of spacing damping bodies 4.3 and a holding plate 7 inserted into a support groove 1.5 in the body of step 1 and fastened to it by a screw 8 the outer body 4.1 of the elastic joint 4 is held against rotation in a recess 1.4 of the body of stage 1.
  • the drag roller 2 is guided on a running rail 5 and a chain roller 3 of the transport chain 10 on a guide rail 6.
  • a possible fastening device 9 is shown on an outer link 10.2 or on an inner link 10.1 of the transport chain 10.
  • the outer body 4.1 of the elastic joint 4 is inserted against rotation and secured by the holding plate 7.
  • a driver pin 12 arranged on a support 11 serving as a supporting element engages in the inner body 4.2 of the elastic joint 4.
  • the support 11 lies on the plates 10.3, 10.4 of an inner link 10.1 or an outer link 10.2 of the transport chain 10 and is connected by means of an anchoring element 15 which has a pin 15.1 which can be engaged in a bore 10.5 of the plates 10.3, 10.4 of the chain link 10.1, 10.2.
  • the anchoring element 15 is clamped to the support 11 by means of a screw 16 and a nut 17, the screw 16 being guided in an inner guide bore 11.2 when fastened to an outer member 10.2 and in an outer guide bore 11.1 when fastened to an inner member 10.1.
  • the part of the support 11 which faces the side of the chain link has ribs 11.3 which engage in corresponding upper cutouts 10.6 provided in the plates 10.3, 10.4.
  • a support 19 is connected to each chain link 10.1, 10.2 with the same anchoring elements and securing devices shown in FIGS. 3-6.
  • the support 19 has a bore 19.1 provided for the rotationally secure reception of the outer body 4.1 of the elastic joint 4.
  • a driver pin 22 with a cylindrical bearing part 22.1 and a button handle 22.2 is mounted in the body of a step 21.
  • a locking spring 13 prevents the driving pin 22 from rotating and shifting.
  • the grooved tread of level 21 receives number 21.1 and the side plate of level 21.3.
  • the endless step belt 14 consisting of a forward flow 14.1 and a return 14.2 is shown schematically.
  • the lead 14.1 of the step belt 14 is composed of a lower horizontal 14.3, an oblique 14.4 and an upper horizontal track 14.5.
  • the steps 1 fastened to the conveyor chains 10 each have a grooved tread surface 1.1, a grooved front part 1.2 and two drag rollers 2.
  • the chain rollers 3 are arranged between the plates or next to the plates of the chain links 10.1, 10.2 of the transport chain 10.
  • the drag roller 2 is guided on the running rail 5 and the chain roller on the guide rail 6.
  • the elastic joint 4 provided between the individual steps 1, 21 and the transport chains 10 is installed in such a way that at least in the area of the inclined part 14.4 of the lead 14.1 of the step belt 14 and in the transition arches connected thereafter to the steps 1 , 21 a torque is exerted such that a force acts on the drag rollers 2.
  • the trailing rollers 2 are thereby pressed against the running rails 5 during operation and the stage 1 does not come to a halt when the running rails 5 are idle, even when they are dirty.
  • a holding plate pivotably arranged with a hinge on the body of the step could also be provided.
  • a driver bolt with a compression spring could also be provided.
  • the compression spring is held under tension by the locking spring in order to pull the driving pin into an expansion position after pulling out the locking spring, in which the driving pin is completely drawn into the hole arranged in the side plate of the step.
