Definitions

  • the invention relates to a single or multi-level lift for vehicles, in particular underfloor lift, wherein the punch has at least one arranged in a vertically extending protective and guide element cylinder / piston unit whose stroke is guided by a stationary sleeve.
  • stamps While in the stamped version of the stamp is located centrally below the vehicle to be lifted, the stamps are positioned on the two longitudinal sides of the vehicle in the multi-punch design, which then depending on the vehicle weight and vehicle length to four- or six-stamp stages can act.
  • a protective element in the form of a surrounding cylinder in particular a Pipe accommodate.
  • this cylinder carries along the lifting movement of the punches and is displaceably guided in a stationary sleeve which is concreted in the workshop floor.
  • the present invention is based on the object, lifting platforms with the features described above more cost-effectively than before, without affecting the precision and stability of the vertical guidance of the cylinder / piston units.
  • the protective and guide element surrounding the cylinder / piston assemblies is no longer designed as a cylinder, but as an I-beam, and that this I-beam laterally so beside the at least one cylinder / piston Aggregate is positioned, that the latter extends at least predominantly in the space between the flanges and the web of the I-beam.
  • This I-beam is at the same bending stiffness as a cylindrical tube much cheaper than the latter produced, since it requires no expensive post-processing.
  • its special positioning relative to the cylinder / piston unit offers the advantage that the latter can be accommodated in a well-protected manner by the web and flange areas of the I-beam.
  • the invention offers the advantage of better accessibility of the cylinder / piston unit, because it is free at the opposite side of the web of the I-beam. As a result, its disassembly is possible without removing the I-beam, whereas in the previously conventional cylindrical protective elements, the protective element first had to be removed in order to advance to the cylinder / piston unit.
  • the I-beam is designed as a wide-flange carrier, optionally with over-wide flanges as cold-rolled I-beam. This increases both the rigidity of the carrier and the wider flanges improve both the precision of the vertical guidance in the cuff and the protection of the cylinder / piston assembly in the space between the flanges.
  • the I-beam described above is a rolled solid part
  • the I-beam may instead be formed as a hollow profile
  • this hollow profile has been produced from longitudinally welded together sheets.
  • the training as a hollow profile has the advantage that more functional parts can be accommodated protected in the interior.
  • a further guide element in particular for a wheeled free lift, in the I-beam designed as a hollow profile.
  • This further guide element can be designed as a solid I-profile, so that it optimally fits into the hollow profile of the I-beam and can be displaceably guided in it via sliders or bearings.
  • the I-beam extends almost over the entire lifting height, that is, almost over the entire cylinder height to the upper end of the piston rod when the piston rod is in its retracted state.
  • the invention offers the possibility to combine the I-beam with another cylinder / piston unit.
  • This further unit could be arranged directly next to the first unit.
  • the additional cylinder / piston unit is not used for the lifting movement of the punch, but for the lifting movement of a Radokhebers.
  • the lifting platform is a multi-stage platform, it is recommended that the I-beam assigned to one side of the vehicle be rigidly connected to the oppositely arranged I-beam for the other side of the vehicle by a solid transverse strut, preferably at the lower end of the I-beam to connect to support the synchronization of both stamps.
  • the casters in the cuff are suitably arranged so that they roll on opposite broad sides of the flanges, and expediently on the flange outside, and that they roll on opposite narrow sides of the flanges.
  • the I-beams are thereby reliably guided in all horizontal directions.
  • two rollers should be arranged vertically spaced one above the other.
  • FIG. 1 recognizes the two juxtaposed stamp 1 and 2 consisting of vertically movable Breitflanschmoin 11 and 21, which preferably consist of precious metal and are guided vertically displaceably in sleeves 12 and 22 respectively.
  • the sleeves 12 and 22 are concreted in the bottom area of the workshop, while the stamp 1 and 2 extend with its lower portion in a corresponding recessed pit inside.
  • the drive of the two I-wide flange 11 and 21 takes place in each case by a cylinder / piston unit, of which only the unit 13 of the left punch 1 can be seen in the drawing.
  • Its cylinder 13a is supported on the foundation of said pit, so remains stationary while its piston rod 13b can be moved upwards.
  • This piston rod is connected to its associated I-beam 11 and forms the drive for its lifting movement.
  • the connection of the piston rod 13b with the associated I-beam 11 via a common head plate 14.
  • On this head plate 14 can support arms, Auffahrschienen or buffers for vehicle reception be mounted, expediently by a screwless, positive connection or the like.
  • the two I-beams 11 and 21 are rigidly connected to each other by a common transverse strut 30; This cross strut thus makes the lifting movement.
  • the position of the cylinder / piston assemblies relative to their associated I-beams is chosen so that the cylinder / piston unit is - preferably completely - in the space between the two flanges of the I-beam, so more or less closely adjacent to the bridge connecting the two flanges, as shown in FIGS FIGS. 2 to 4 becomes clear.
  • I-beam 11 The leadership of the connected to the cylinder / piston unit 13 I-beam 11 is carried by rollers which are rotatably mounted with a horizontal axis in the sleeve 12, namely by rollers 15 a and 15 b, on the broad sides of the flanges 11 a and 1 Unroll on the outside and by 90 degrees offset rollers 16a and 16b, which roll on the narrow sides of the flanges 1 1 a and 1 1 b.
  • the I-beam 11 is thus centered on all four peripheral surfaces by the rollers 15a, 15b, 16a and 16b and slidably guided.
  • FIGS. 3 and 4 show vertical sections in the cuff area. It is clear that the four rollers 15a to 16b are arranged in pairs, namely by parallel up or down offset rollers 15a 'to 16b' are added, which provide the I-beam practically two height-offset guide areas and thus reliably protect against tipping.
  • rollers are rotatably mounted on their terminal projecting axes in their associated sleeve. It is essential that at least some of the rollers, in particular two mutually perpendicular rollers of four circumferentially successive rollers, are adjustable in the radial direction, so that a play-free installation of all rollers can be realized on the I-beam.
  • the tracks along which the I-beams roll on their rollers are expedient no special machining machining more subject. Rather, it is sufficient if the I-beam receive a plastic coating at least in the region of these tracks.
  • FIG. 5 shows a variant in which in each case a second cylinder / piston unit is installed in the remaining space between the I-beam.
  • This cylinder / piston unit is supported with its cylinder on its associated I-profile 11 from; so far it is in FIG. 5 not visible. But it recognizes its associated piston rod 17 and 18, which is independent of the lifting movement of the I-beam 11 and 21 up out mobile to operate in a conventional manner a wheeled lift.
  • this additional cylinder / piston aggregate for the wheel squeegee is arranged on the side of the web 11c of the I-beam opposite the cylinder / piston unit 13 or 23, thus taking advantage of the free space remaining there.
  • the head plates 14 and 24 again intended for receiving support arms, Auffahrschienen or buffers and the like for attack on the vehicle.
  • FIG. 6 shows an alternative design in which the I-beam is not formed as a solid component, but as a hollow profile 31. In principle, it still has an I-shaped cross-section, but resembles an H-profile due to the longer flange areas and the shorter web. It can be made by deformation of a pipe. In general, it is cheaper weld together several sub-profiles with matching bends in the longitudinal direction.
  • the I-beam 31 is guided in the same way as the I-beam 11 in FIG. 2 , Its lifting drive can equally be done by the cylinder / piston unit 13 with cylinder 13 a and piston rod 13 b.
  • a guide member 37 for a Radokheber It is essential that 31 more lifting elements can be accommodated in the interior of the hollow profile, in the embodiment, a guide member 37 for a Radokheber.
  • the guide member 37 thus corresponds in its function to the Radokhebern 17 and 27 in FIG. 5 , only now it is housed in the hollow section 31 encased on all sides.
  • the wheel jack 37 may also have the shape of an I-profile so that it extends into all the cavities of the hollow section 31, without filling them.
  • sliders 38a to 38d For vertical guidance of the wheel-free elevator 37 in the hollow profile 31 are sliders 38a to 38d, which are mounted either on the hollow profile or on the wheel jack and allow a low-friction relative movement of the other component.
  • the sliders 38 are arranged in the flange of the hollow section 31 and U-shaped, such that they have on their flanges of the Radokhebers 37 side facing a guide slot into which the flange of the Radokhebers 37 protrude.
  • the drive of the Radokokbers 37 relative to the hollow profile 31 is analogous to FIG. 5 by a further cylinder / piston unit 33a, 33b, which is arranged on the cylinder / piston unit 13 opposite web side of the hollow profile.
  • Its piston rod 33 b is - expediently near its upper end - connected to the wheel free lift 37 and either performs only an additional stroke to lift at a lifted by means of the hollow sections 31 vehicle wheels or she performs the full stroke, in which Vehicle is driven on the chassis to the desired height, while the rails connected to the hollow section 31 remain down.
