Definitions

  • the invention relates to a hydraulic rope elevator with a backpack-guided car and a drive device arranged between the car guide rails.
  • the invention is therefore based on the object of designing a hydraulic rope elevator with a backpack-guided car and consequently three-sided accessibility of the elevator shaft and the car in such a way that it can be provided with a better, simpler and more economical working drive.
  • the invention provides that the drive device comprises a pull cylinder with a counterweight attached and a cable pull comprising a fixed and a loose roller, the counterweight, the deflection roller on the counterweight and the pull cylinder being arranged essentially in the vertical plane of the car guide rails and the cable acts laterally in the longitudinal center plane on a boom or a cross member of the car.
  • the elevator according to the invention represents a combination of the construction with a backpack-guided car and the drive device with traction piston hydraulics, which was previously preferred because of the three-sided accessibility and the stress of only one shaft wall by the drive device, and a further special feature is that the car only uses one and more the cable pulling the car is not actuated in the central longitudinal axis.
  • this enables a configuration such that a scaffold formed from the car guide rails and a plurality of cross members can carry the counterweight guide rails, the pull cylinder, the upper cable receptacle and the upper deflecting roller, and thus the entire drive can be a prefabricated component, which is also not a special one Breakouts and breakthroughs in the elevator shaft, but can be easily flange-mounted on a shaft wall.
  • the upper deflection roller i.e. the deflection roller in the shaft head
  • the deflection roller on the counterweight is arranged inclined to the deflection roller on the counterweight, in such a way that the cable sections between the fixed upper cable receptacle and the deflection roller on the counterweight, between this and the Deflection roller on the shaft head and finally run vertically between this deflection roller on the shaft head and the car.
  • the lifting and lowering of the elevator does not result in any changed lever conditions due to a more or less inclined or vertical positioning of the cable pulls, as is the case with a number of traction piston hydraulics previously proposed, but all of them with central suspension and guidance of the elevator car work so that at least two, often also three shaft walls are blocked and in principle a maximum of two walls is available as an access option.
  • the inclination of the upper deflection roller has the additional advantage that the rope suspension can be moved into the current center of gravity of the car by rotating the roller around the common rope run-up or rope run-off point, which is particularly the case with so-called "one-piston side systems", systems with a cylinder to the side of the door is important.
  • the construction according to the invention allows a very compact design, since the pull cylinder, the counterweight, the deflection plate on the counterweight, the guides for the counterweight, the cable guide and the deflection roller unit including the roller block in the shaft head between the guide rails and are not arranged above the car, as was the case with the previous train cylinder hydraulics.
  • the drive-over heights specified in the relevant regulations (TRA, EN 81) and thus the minimum headroom dimensions are very small.
  • the deflection pulley unit in the shaft head and the mounting bracket for the pull cylinder can be attached directly to the structure or the rail using standard fastening elements (dowels, screws, Halfeniron etc.), no additional structural preparations such as cutouts in the shaft head or in the pit or that are required
  • the introduction of cross members is required, which makes this system ideal for retrofitting existing systems.
  • All main components of the drive device in particular the deflection roller unit in the shaft head, the support for the pull cylinder, the counterweight with rope pulley and guides as well as the brackets for the main and counterweight guide can be completely prefabricated and assembled, which significantly reduces the assembly time of the elevator.
  • the pulleys are designed with regard to their number of grooves in such a way that they can accommodate the additional safety ropes required by the applicable regulations.
  • FIG. 1 shows the elevator shaft 1 which is surrounded by the side walls 2 and the rear wall 2a.
  • a frame-shaped scaffold 3 which is formed from two car guide rails 4, upper and lower cross members 5 and 6 and further interposed cross members 7.
  • the car ropes 10 and the counterweight ropes 11 run vertically from the cable holder 15 on the upper cross member 5 via the rope pulley 12 on the counter weight 19 to the upper fixed deflection pulley 13 on the upper cross member 5 and from there to the rope suspension on the frame 14 can be seen in particular from FIG.
  • the frame-shaped frame 3 including the guide rails 4 and the counterweight guide rails 16 and including the cable pulley 12 is arranged laterally outside the path of movement of the car 17; it is therefore a backpack-guided car.
  • the axes of the two rope pulleys 12 and 13 run obliquely to one another, as a result of which the rope suspension on the frame 14 can take place outside the range of movement of the counterweight. Due to this arrangement, even with minimal space, i.e. in principle, contact between the car 17, the counterweight 19, the support cables 10 and the counterweight cables 11 is excluded with the smallest pitch dimension and the smallest distance to the wall. Another advantage of this arrangement is that by rotating the roller 13 around the common cable run-up or cable run-off point, the cable suspension 14 can be moved into the current center of gravity of the car.
