Definitions

  • the invention relates to a lifting device for lifting and transporting loads. It is designed for parts that have a high weight and upwards a flat spatial extent, such as stone slabs, kitchen worktops, glass plates, etc.
  • a lifting device By means of a lifting device, heavy and unwieldy objects can be transported and lifted after transport. Thus, e.g. smaller distances between a transport vehicle and a construction site are overcome.
  • the invention can also be used to locally increase components without manual effort to facilitate installation.
  • the device has two axles to which wheels with air-filled tires (drawing B 7) are attached.
  • the axles are connected by a bridge consisting of a steel, wood or other durable material carrier centered (horizontal).
  • Perpendicular to the bridge (vertical) is a linear axis (drawing B 1) e.g. with a pusher as an integrated spindle drive - (drawing B 2) set up.
  • This axis is preferably located in the center of gravity of the vehicle.
  • Load bearing surfaces are attached around this axis (drawing B 4), which by means of a lifting mechanism, e.g. be raised by means of the ball screw.
  • the lifting mechanism may e.g. by an electric motor (drawing B 5) by means of an intermediate transmission (drawing B 6) driven.
  • the load-bearing surfaces have U-profiles in which the loads to be transported or lifted are stored parallel to the linear axis on the load-bearing surface - ie vertically.
  • This arrangement makes it possible to pick up stone slabs, kitchen worktops and other heavy bulky items with a small height but large lateral dimensions and move them manually by moving this chassis.
  • the air-filled wheels make it possible to overcome unevenness such as sleepers and smaller steps. Arrived at the destination, the transported object can be lifted by the operation of a control bottle described below.
  • the limit switches attached to the device prevent the drive from moving beyond the end position.
  • the chassis is made of steel profiles of quality S235 J2G3. However, from a static-constructive point of view, there are no future objections to a design made of high-strength aluminum AlZn4,5Mgl.
  • the four wheels on the chassis are designed as pneumatic tires, which brings significant advantages especially when transporting over thresholds.
  • the load suspension is made of structural steel of quality S235 J2G3.
  • the load is taken up by a U-profile and can e.g. be transferred to the ball screw nut.
  • the load is taken in the gallows of the chassis whereby the moment load is removed.
  • the vertical load is transmitted to the spindle.
  • the spindle is powered by a 24 V DC electric motor.
  • the engine is followed by a gear ratio of 1:10, which converts the required torque and the required speed.
  • a brake is flanged on the engine which is only opened by pressing the control bottle.
  • the brake prevents a lowering of the transport part in the non-actuated state. There is thus a self-locking.
  • the power transmission takes place via a keyway connection between the hollow shaft of the transmission and the ball screw spindle.
  • the linear drive consists of a ball screw 25 ⁇ 10 with a corresponding ball screw nut.
  • the length of the spindle is 1192mm.
  • the lifting and lowering of the load takes place via a control bottle which is connected to the control via a cable.
  • the device is equipped with inductive limit switches which stop the movement in the end positions. Furthermore, there is an emergency stop button on the control bottle which stops all movements when pressed.
  • the unit is powered by two 12V lead gel batteries connected in series.
  • the object of the invention is a lifting device that ensures the safe transporting and lifting of heavy, unwieldy plates.
  • heavy and unwieldy loads such as e.g. Stone slabs, glass plates and kitchen worktops can be transported and brought to the correct height for installation. For installation then the plate to be installed no longer needs to be raised, but can be moved laterally.
  • a device consisting of two axes of air-filled wheels connected by means of a steel girder (see drawing A) on which, at the center of gravity of the vehicle, a linear axis with integrated spindle gear is mounted, with support devices raised by a lifting mechanism or can be lowered, solved.
  • the device is of simple construction and consists essentially of only two pneumatic-filled tires which are centrally connected by means of a support on which is mounted an axis with an integrated lifting mechanism perpendicular to it, around which a load-bearing means (bottom and top) are arranged , which can be raised or lowered by means of a lifting mechanism (claim 1).
  • a ball screw drive and the load bearing with a thread corresponding to the ball screw nut provided as a lifting mechanism (claim 2).
  • the lifting mechanism may also consist of a spherical shaft which is capable of displacing loads along the axis arranged perpendicularly on the support connecting the two axes, upwards and downwards respectively (claim 3); it may also consist of a hydraulic device (claim 4), a cable pull (claim 5) or a chain (claim 6).
  • the load receptacles are mounted at the bottom and at the top of the axis perpendicular to the carrier connecting the two axes and preferably consist of Steel or other durable material and are provided with one or more U-profiles for receiving the load or loads, thereby the loads can be vertically transported safely and raised (claim 7). At this load bearing a locking possibility is attached, which fixes the parts to be moved, so that a lateral tilting is prevented (claim 8).
