Definitions

  • the present invention relates to a guide device for the running elements of endless conveyors such as escalators and the like, in which main and trailing rails are fastened to a carrier frame via rail holders.
  • the running elements are supported and guided along their endless path, with the aim of achieving a running of these running elements that is as quiet and vibration-free as possible.
  • the guide devices also serve to horizontally guide the tread surface of the running elements designed as stair treads, as they pass through the upper run, both in the horizontal and in the ascending area and in the transitions.
  • the running tracks subject to wear are generally connected to the support frame in a manner which is difficult to detach or even inseparable, so that there is no possibility of subjecting them to a surface treatment, regardless of the support frame, or of rapidly and easily replacing them if there is increased wear .
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of creating a guide device for endless conveyors such as escalators and the like, which can be assembled with great effort and without any device on the construction site with great accuracy and whose tracks are easily removed and replaced can.
  • the innovation also aims to create a guiding device that can be constructed from a few standard parts that are manufactured in large series and that simplifies storage and makes production cheaper.
  • the rail holder carrying the main and trailing rails has at least two in the corresponding centering on its fastening side provided with at least one fastening hole receiving a fastening means
  • the dovetail clamping device consisting of a fixed clamping jaw arranged on the rail holder and a clamp that can be moved by means of a dovetail connection on the rail holder.
  • the centering knobs and the fastening hole on the rail holder are arranged in mirror symmetry with respect to the middle of the rail holder that is perpendicular to the fastening and rail support side.
  • the rail supports in the dovetail clamping devices are chamfered in the area of the run-in and outlet of the rails.
  • the rail holder has either a rectangular or an L-shaped cutting surface in the central plane of the rail holder.
  • the L-shaped rail holder is equipped with a finger-shaped extension to brace the mating guides between its long side and the side plate.
  • the guide device according to the invention is excellently suitable for assembly on the spot where work often has to be carried out under difficult conditions due to structural or other difficulties. Any shortcomings in the execution of the work cannot have a detrimental effect on the synchronism of the running elements, since the accuracy of the step guidance is determined by the prefabricated individual parts manufactured with tight tolerances.
  • the modular assembly elements according to the invention are designed in such a way that they can be easily assembled on site as well as easily disassembled and have a relatively low weight.
  • the tracks subject to wear can be easily removed for maintenance or replacement by loosening the dovetail clamp and reassembled without a device.
  • the essential elements of the construction concept according to the invention namely the rail holder, the counter-guide, the rivet and screw connections and the dovetail clamping device are function-related and not system-related, that is, they can be used again and again regardless of a system in the same design.
  • the adaptation for the individual application takes place via the side plates or by positioning the corresponding centering openings.
  • connection technology With regard to the construction elements such as the connection technology, one can therefore speak of a modular structure. For a large number of systems, such as for the standard widths of 80 cm and 110 cm, the same individual parts can be used, which are produced in standard sizes and which are characterized by easy handling and variety of possible uses.
  • Fig. 1 shows the guide device according to the invention based on the lower end of the stairs, how the step-shaped platforms are brought out of their inclined path into the horizontal path or vice versa and reverse their direction of movement.
  • the following considerations apply mutatis mutandis to the sloping section and the top of the stairs, both of which are not shown here.
  • Continuous escalators are usually driven by an upper sprocket, which sits on a motor-driven main shaft, and consist of a large number of step-shaped platforms that are articulated on both sides. At the bottom of the stairs, the chain runs around idler sprockets 1, 2, which are often under the influence of a tension spring to maintain the chain tension, as is familiar to the person skilled in the escalator technology.
  • a rail system is available for the upper, load-bearing strand and for the lower returning strand.
  • Both rail systems have main rails 3 for the chain rollers on the stairs, whereby Counter guides 4 are mounted in the area of the reversing stations.
  • Trailing rails 5 are provided for the trailing rollers, which, however, only extend over the ends of the stairs in the lower run.
  • the main rails 3.1 and the follower rails 5.1 are curved between the inclined sections and the horizontal sections in order to effect the step transition required here.
  • the distance between the curved main rails 3.1 and trailing rails 5.1 changes continuously in this area in order to ensure the gradual transition from platform to step structure - or vice versa depending on the direction of the step.
  • the main rails are designed as channel-shaped guides 6 with a semicircular end part 7.
  • the running rails 3, 5 in their various forms of construction are assembled without a device by means of rail holders 10, 11 and additional structural elements with the support frame, with the tolerances being used to manufacture them Individual parts, the parallelism and the alignment of the running tracks are automatically guaranteed.
  • the rail holder For the corresponding vertical and horizontal Positioning the running rails, however, requires two embodiments of the rail holder: a rectangular rail holder 10 and an L-shaped rail holder 11. As part of the guide device, the rail holders thus act as central connecting elements between the support frame and the running rails.
  • the side plates 20 are initially to be screwed to the separately machined U-shaped cross member 21. Then the centering knobs 26, 27 on the rail holders 10, 11 are brought into engagement with the corresponding centering openings 28, 29 in the side plates 20, thereby fixing the rail holder and side plates in their mutual position and connected to each other by means of the fastening means 30 in the fastening hole 31.
  • the Spanniet 32 used here can be replaced by a screw or any other releasable or non-releasable connection means.
  • the guide plates 20 fulfill the double function as a precision template during assembly and as support elements for the rail holders.
  • the rail holders 10, 11 each have on their rail support side 10.1, 11.1 a dovetail clamping device 35, which is used to clamp the running rails 3, 5 on all sides.
  • the principle of device-less assembly is consistently continued when fastening the drawn counter-guides 4. The same are inserted into the rail holder 11 up to the stop 22 of the finger-shaped extension 23 and braced with it on the side plate 20.
  • FIG. 3a The assembly of the rail holder, side plate and running rail according to the invention is shown in detail in FIG. 3a for a rectangular rail holder 10 and in FIG. 3b for an L-shaped rail holder 11.
  • FIG. 3b The following description of the connection structure applies in the same way to both types of rail holder.
  • Both the rectangular and the L-shaped rail holder are provided on their fastening side 10.2, 11.2 with two centering knobs 26, 27 and have a dovetail clamping device 35 on the rail support side 10.1, 11.1.
  • the mounting hole 48 serves to receive a fastener for the cultivation of the Rail holder to the side plate 20.
  • the rail holder is manufactured using the die-casting process, so that the centering knobs 26, 27 can be formed as castings with the required tolerances.
  • the side plates 20 are provided in the area of the rail supports 10, 11 with centering openings 28, 29, which serve as reference points and, in cooperation with the centering knobs 26, 27, determine the parallelism and alignment of the running rails on the rail holders 10, 11.
  • the main and trailing rails 3, 5 have a dovetail-shaped profile 54 along their underside in order to be clamped in the dovetail clamping device 35.
  • the centering knobs 26, 27 on the rail holders 10, 11 are brought into engagement with the corresponding centering openings 28 29 in the side plate 20, and the whole is connected by a rivet connection 55.
  • the Spanniet was chosen for cost reasons, but is not intended to limit the invention in any way. A connection with a screw or other fastening means is also conceivable.
  • the centering knobs 26, 27 In cooperation with the centering openings 28, 29, the centering knobs 26, 27 not only ensure the exact positioning of the rail holders on the side plate, but also essentially take over the thrust forces that occur.
  • the rivet or screw connection 55 only serves to absorb the tensile force resulting from the tilting moment.
  • the dovetail clamping device 35 fixes the main and trailing rails 3, 5 on their running surfaces 55, the chain and drag rollers 58, 59 move rigidly on all sides on the rail holders 10, 11.
  • the dovetail profile 54 which extends along the entire length of the running rails 3, 5, serves ideally to hold the running rails rigidly but easily detachably on the rail supports by clamping. With a sufficient moment of inertia, the dovetail-shaped profile of the running rails enables a secure fastening of the running track, which ensures sufficient parallelism and alignment of the running rails even when the escalator is heavily loaded.
  • bevels 56 are provided in the region of the rail ramps and drains in order to be able to better accommodate the running rails bent in the transition region from the horizontal part to the inclined part.
  • the cant 61 is required if a force rivet 55 is used as the connecting means. With it, the span of the connection given by the side plate and the rail support should be adapted to the rivet used, since it is only commercially available in graded lengths.
