Definitions

  • the invention relates to a chassis of a rail-traveling lifting device according to the preamble of claim 1.
  • the ceiling lift is moved along the rail by means of a trolley which has a drive unit and a support unit which are connected to one another by an articulated rod.
  • the drive unit has wheels that can be rolled on the running surfaces of the running rail, which are supported on the rail and are rotatably mounted on a common carrier.
  • a motor is provided as the drive element, the drive forces of which are transmitted to the chassis via a friction wheel abutting a friction surface of the rail.
  • the tread and the friction surface are usually arranged parallel to each other.
  • the support unit also has a running gear with wheels that roll on the running surfaces of the rail like the wheels of the drive unit. They are also pivoted on a common carrier.
  • the carrier is connected to the lifting device below the rail.
  • the friction wheel is pressurized on the Friction surface.
  • the contact pressure is to be chosen so that even at maximum load an drive properties are guaranteed. So the friction wheel can also Do not turn the maximum load.
  • the friction wheel subject to high wear.
  • the elastic friction wheel experiences further through the Force-applied concerns on the friction surface if the Ceiling lift a deformation that initially occurs when the lift is restarted may be associated with an uneven run.
  • the chassis is due to the Spring loading is often difficult to move by hand.
  • DE 26 18 516 C2 is a trolley of a lifting device that can be moved by rail known, which has an impeller, which serves as a supporting and drive wheel.
  • the impeller rolls on a tread extending in the longitudinal direction of a running track, which as The friction surface of the impeller is used.
  • An additional wheel is provided as a further impeller Driving direction seen at a distance from the driven impeller at one end of a lever pivotable lever is rotatably mounted. This additional wheel rolls in the operating state of the Trolley not on the tread of the rail; it is in normal operation a parking position.
  • the jockey wheel is only activated in the event of failure or malfunctions in the drive Actuation of the lever placed on the tread by the free end of the lever as Double lever trained lever is pulled down vertically.
  • a chassis is known from US 1,367,522, which, however, for Drive does not have a friction wheel applied to a running surface of a running rail having.
  • the drive takes place via a gear, which, for example, in a Rack of the rail engages.
  • the drive via interlocking teeth is required no contact pressure, like that for driving the undercarriage on a friction surface adjacent friction wheel is the case.
  • the object of the invention is a chassis in the preamble of claim 1 mentioned type so that the friction wheel is subject to little wear and despite maintenance friendliness even at maximum load a smooth drive guaranteed.
  • the lever is a double-arm lever on which the friction wheel is mounted on one side and from which the lifting device is supported on the other side.
  • Such a chassis ensures that the friction wheel is pressed depending on the load on the friction surface of the rail. In the case of a large load, the friction wheel is thus subjected to a large force; if there is no load, the friction wheel is only loaded by the weight of the lifting device. This is usually low. A deformation of the friction wheel, especially when not used for a long time, is avoided in the chassis according to the invention.
  • a light construction of a ceiling lift is achieved in that the running rail a downwardly open hollow profile-shaped rail with treads arranged inside is.
  • a stable construction of the ceiling lifter results when a T-shaped or double-T rail is used as a rail, on one flange of the tread and Friction surface are formed.
  • the friction wheel and the lifting device on the double lever are expediently flying stored. Due to the good accessibility of the components, this enables simple Repair and easy replacement of worn components.
  • the elongated hole is advantageously convex toward the pivot axis, so that no subsequent, automatic displacement of the lifting device to the other side he follows.
  • the double lever In order to achieve a high degree of flexibility when transporting people, the double lever is in its middle connected to the girder via a gimbal-like joint. This is ensures that when the load swings in the direction of travel the lever arm of the Carrier and thus the relative contact pressure of the friction wheel changes only slightly in addition, a safe, simple lateral pivoting of the lifting device is possible.
  • the lifting device be rotatably supported about a vertical axis is so that the person to be transported is turned into the most favorable position can.
  • the undercarriage 1 shows a trolley 1 of a lifting device 3 which can be moved on a running rail 2.
  • the undercarriage 1 has running wheels lying one behind the other in the longitudinal direction of the rail 4, which are arranged in pairs next to each other.
  • the wheels 4 are one common carrier 5 connected to each other and freely rotatably mounted thereon.
  • the carrier 5 extends between the wheels 4 partially to below the Track 2 and is via a pivotable double lever 7 supported on the carrier 5 connected to a friction wheel 8.
  • the friction wheel 8 is at a free end of the double lever 7 rotatably supported on the fly and driven by a motor 9 (see FIG. 3).
  • the other At the end of the double lever 7, the lifting device 3 is pivotally attached on the fly.
  • the friction wheel 8 Due to the dead weight of the lifting device 3 acting on one end of the double lever 7, the friction wheel 8 is pressed against a friction surface 10 of the travel rail 2 already in the load-free state.
  • the contact force counteracts only the dead weight of the friction wheel 8 and the driving motor 9. It depends on the selected one Lever ratios of the double lever 7 and can be adjusted via the choice of the suspension point so that the friction wheel 8 is in contact with the friction surface 10 under light pressure in each case under no load. In the loaded state, the contact pressure is proportional to the load.
  • a pair of wheels 4 is the friction wheel 8 arranged opposite each other.
  • the running surfaces 6 and the friction surface 10 of the running rail 2 run parallel to one another in the exemplary embodiment.
  • Fig. 2 shows a special embodiment of the double lever 7.
  • Fig. 2 shows that the double lever below the pivot axis 11 is essentially horizontal
  • the slot 12 is convex towards the swivel axis. This allows the lifting device 3 each from one side of the vertical plane (from one side of the fulcrum of the Swivel axis) to the other side.
  • the lifting device 3 and the friction wheel 8 on the same side, the friction wheel 8 is relieved and a particularly light manual displacement of the chassis 1 on the rail 2 is made possible.
  • the double lever 7 can alternatively to the exemplary embodiment also via a joint gimbal type to be connected to the carrier 5.
  • FIG. 3 shows in a first cross section through the friction wheel 8 of a chassis, the special on a downwardly open hollow profile-shaped travel rail 2 arranged inside Treads 6 is movable.
  • FIG. 4 shows a second cross section corresponding to FIG. 3 with cut through the axes of a pair of impellers 4.
