Definitions

  • Guide device and safety device for an elevator running on column-like guides which automatically prevent transmission of misalignment of the guide to the car and unintentional engagement of the safety device.
  • Swiss Patent No. 386 651 describes and shows a sliding guide shoe mounted in a spherical cap, which, through this type of mounting, has additional degrees of freedom for adapting movements to a twisted guide.
  • columnar guides have a protruding brake leg, which is a strip of the rotation errors Safety gear and thus an unintentional engagement of the same could result.
  • a protruding brake leg which is a strip of the rotation errors Safety gear and thus an unintentional engagement of the same could result.
  • US Patent No. 5,159,995 describes and shows a wedge catcher with two guide rollers.
  • the two sprung guide rollers are firmly connected to the safety gear and have a limited spring travel, which is smaller than the air gap between the brake wedge and the braking surface.
  • the invention is distinguished, inter alia, by the fact that the guide device is arranged on the horizontal plane so as to be rotatable about a pivot point lying in the guide cross section, and that the guide device is provided as a support for a conventional safety gear.
  • the rotational mobility is made possible by circular arc-shaped slots in a holder and sliding guide pins.
  • the roller guide device is guided and held between parallel track roller bearing segments in order to reduce the friction.
  • the safety gear arranged on the guide device is arranged to be displaceable in the vertical direction, the displacement path of which is limited and damped by a stop with a damper located on the elevator car.
  • FIG. 1 shows an elevator car 1 running on columnar guides 2. Above the elevator car 1, roller guides 3 are shown rudimentarily on both sides on a yoke 4.
  • FIG. 2 shows the details of the guide device in the form of a roller guide 3.
  • a guide roller 11 is mounted on the inside at the outer ends of the two legs, the axes of rotation of which are at an angle of, for example Have 90 ° to each other.
  • a third guide roller 11 is mounted between two short fork legs, the axis of rotation of which runs at right angles to the yoke 4.
  • the roller carrier is guided and held between two guide plates 7, which have a short circular guide slot 13 with the radius of a movement circle 15 with the center 18 lying in the profile cross section.
  • the roller carrier 6 is fastened by means of a guide pin 9 passing through it within the length of the Guide slot 13 guided horizontally movable.
  • the guide plate 7 is fastened to a cantilever 5, which in turn is firmly connected to the yoke 4.
  • the safety device 8 can be displaced somewhat vertically upwards in the holder 14 and the holder 14 is firmly connected to the leg of the roller carrier 6.
  • a stop 12 is firmly connected to the yoke 4 and projects with the left end over the upper end face of the safety device 8.
  • the safety device 8 encompasses a brake leg 10, which is designed as a protruding extension of the guide 2.
  • the two lateral guide rollers 11 each run on two shaped, flat running surfaces 20 of the guide 2.
  • the middle guide roller 11 runs on a flat running surface 21, which is formed on the curve of the guide 2. 16 and 17 indicate possible twist angles of the guide 2.
  • the boom 5 is omitted and a direct view of the Given roller support 6. It can also be seen how the roller carrier 6 is guided and held between the lower and upper guide plate 7, and its continuous guide pin 9, which opens into the lower and upper guide plate 7.
  • a buffer is designated by 19, which transmits the sudden deceleration, which is suddenly triggered, to the elevator car 1 in damped braking.
  • wedge catching devices can still be used in an upwardly expanded speed range.
  • the safety device 8 When the safety device 8 is triggered and becomes effective, no force is exerted on the guide device because the safety device 8 moves upward when it falls into its holder 14 and then transmits the braking force to the yoke 4 to the elevator car 1 via the buffer 19 and stop 12.
  • the extruded profile of the guide 2 can have slight twists over its entire length, which is indicated somewhat exaggeratedly by the two twist angles 16 and 17. Due to the described mounting of the roller carrier 6 with its possible displaceability in a horizontal plane on a movement circle line 15, the roller carrier 6 can follow these rotations without any transfer of these movements to the elevator car 1.
  • the center of the movement circles 15 is also the center 18 of the profile cross section of the guide 2.
  • the track dimension between the guides 2 is set precisely during assembly, so that the guide device only has to absorb the twisting errors and thus the elevator car 1 does not experience any undesired lateral movements.
  • the guide slot 13 is dimensioned such that there is still some reserve path in the event of the greatest twisting error of the guide 2.
  • the solution shown in the drawings is a basic solution.
  • special attention is paid to small friction for the sliding movement at the same time, sufficient stability was ensured.
  • the guide plates 7 can be spaced apart from one another at two locations on a suitably adapted extension arm 5 and thus serve the roller carrier 6 as a stable double guide.
  • bypassing a special lubrication device, blocking or jamming is prevented at the local sliding surfaces by means of appropriate material pairing.
  • the guidance and holding of the roller carrier 6 can be provided for special cases with segments of roller bearings, the grooves of which are designed as circular segments of the movement circle 15.
  • a second variant for a flexible storage and guidance of the roller carrier 6 is shown in Fig. 4 and Fig.5.
  • the roller carrier 6 is held and guided by means of two elastic bearings.
  • a first elastic bearing 23 is arranged on the rear of the roller carrier 6 behind the guide roller 11 and at the same height as its axis.
  • a second elastic bearing 24 is arranged under the right leg of the roller carrier 6 behind the right guide roller 11.
  • the axes of the two elastic bearings 23 and 24 are arranged at an angle of approximately 90 ° to one another.
  • the first elastic bearing 23 is connected to the yoke 4 via a cantilever 22 and the second elastic bearing 24 is also connected to the yoke 4 by means of a bearing holder 30.
  • the two elastic bearings 23 and 24 each consist of two bearing legs 26 located on the roller carrier 6, a bearing pin 25 forming the bearing axis, a tubular, elastic intermediate layer 28 between the bearing pin 25 and a bearing bore 27 and two pressure disks 29 arranged on the end face of the elastic insert 28.
  • the elastic bearings 23 and 24 or their tubular elastic inserts 28 have the special property that their hardness transverse to their axial direction is at least twice as great as their hardness in the axial direction. This has the effect that the roller carrier 6 is in the plane of the movement circle 15 with a small elastic resistance can follow the possible twists of the guide 2 with simultaneous damped, but firmer mounting in the vertical direction.
  • An elastic insert 28 with such properties can consist, for example, of a stack of perforated rubber washers, which have sufficient radial strength and can be deformed axially in the manner of disc springs with less force. It is important here that the thrust washers 29 have a suitable diameter that is smaller than the outside diameter of the rubber washers or possibly have an arching toward the end face of the elastic insert 28.
  • the device according to the invention, or the roller carrier 6, can also be provided with suitable slide guide pieces instead of the guide rollers 11 for low elevator speeds.
