Definitions

  • the invention relates to a mobile device for reloading a load weighing up to a few dozen tons, such as a steel reel, a cable drum or a molded part, according to the preamble of claim 1.
  • a steel reel or cable drum is essentially cylindrical with a circular cross-section. It encloses an essentially cylindrical cavity with a circular cross section. This cavity traverses the steel reel or cable drum in a horizontal direction from one side to the other of the wound reel or drum.
  • the invention is also applicable to heavy loads with a different shape, for example on molded parts such as pipes and housings made of cement or cast iron, insofar as these loads enclose an essentially cylindrical cavity, the cross section of which can be as long as the surface lines of the load in the horizontal direction in traverse essentially from one side to the other.
  • Reloading devices of the type mentioned at the outset are known, in which the lifting arm is arranged parallel to the longitudinal direction of the chassis and can be moved forward. Appropriate supports are arranged on the front of the chassis and can be retracted and extended or swung in and out.
  • the transfer device can only load and unload the load in its longitudinal direction, for example “at the front”.
  • the chassis when loading and unloading the load, the chassis must be positioned laterally exactly in front of the load in order to avoid dangerous lateral movements of the load and asymmetrical lateral forces on the chassis.
  • This lateral positioning of the undercarriage is time-consuming and also complex in that appropriate positioning means are required for this.
  • the transfer device must either be long enough be to compensate for the tipping moment of the load around the axis of the front wheels, or be wide enough to allow the load to be pulled onto the chassis between the front wheels, or then the lifting arm must be liftable high enough to pull the load onto the Allow chassis over the front wheels. This makes the construction of the transfer device even more complex.
  • the object of the invention is to eliminate the disadvantages mentioned and to propose a reloading device of the type mentioned at the outset, the construction and operation of which are cheaper and simpler than in the known reloading devices.
  • the load is advantageous for the load to be loaded and unloaded from the side, and it can alternatively be carried out on one side or the other of the chassis.
  • the loads can be arranged in a particularly economical manner on both sides of a roadway intended for the transfer device in two rows with cavities oriented transversely to the roadway.
  • the supports can be attached to those places on the chassis where they least weaken the structure of the chassis. If the supports are attached to a sled, they do not affect the structure of the chassis at all.
  • a transfer device according to the invention is shown in a first embodiment.
  • a chassis 1 comprises a support body 2, which is supported via longitudinal members 3 on, for example, four wheels 4.
  • the wheels 4 can be provided with tires, for example, in order to allow the chassis 1 to travel on a level road.
  • the wheels 4 can also be provided with wheel rims, for example, in order to allow the chassis 1 to travel on a track.
  • the wheels 4 can be steered actively or passively and individually or in pairs in a well-known and therefore not shown manner in order to allow the chassis 1 to follow a curve of the roadway or the track.
  • the chassis 1 is essentially movable in its longitudinal direction.
  • a horizontal turntable 5 is supported on the chassis 1 and can be rotated on the chassis 1 about a vertical axis of rotation 6, for example with the aid of drive means, not shown, such as electric or hydraulic motors or hydraulic or pneumatic cylinders.
  • the turntable 5 is shown essentially circular, but it can also have any other shape. With well-known and therefore not shown means such as brake shoes or bolts, the turntable 5 can be secured relative to the chassis 1 against rotation or released for rotation.
  • a main slide 7 is supported, which can be displaced by means of rollers 8 on the turntable 5 diametrically between two end positions in the horizontal direction with the aid of drive means, not shown, such as electric or hydraulic motors or hydraulic or pneumatic cylinders. Therefore, the main carriage 7 can also be displaced in the horizontal direction relative to the chassis 1.
  • drive means not shown, such as electric or hydraulic motors or hydraulic or pneumatic cylinders. Therefore, the main carriage 7 can also be displaced in the horizontal direction relative to the chassis 1.
  • Fig. 1 One of the mentioned end positions of the main slide 7 is shown in Fig. 1, the other in Fig. 2.
  • a well-known and therefore not shown path can be provided on the turntable 5 and formed from profiles or rails.
  • a lifting arm 10 is supported on the main slide 7 via a carrying device 9.
  • the main slide 7, the carrying device 9 and the lifting arm 10 are arranged approximately in a Z-shape with respect to one another, so that the lifting arm 10 protrudes from the main slide 7.
  • the carrying device 9 is provided with a lifting and lowering mechanism which allows the lifting arm 10 to be displaced in the vertical direction relative to the main slide 7 and thus to the chassis 1.
  • a lifting and lowering mechanism is, for example, well known from forklifts and reloading devices for steel reels or cable drums and is therefore not shown.
  • the lifting arm 10 is essentially defined as an elongated body which has a horizontal longitudinal direction and parallel to the direction of displacement of the main slide. From forklift trucks, however, it is also well known to provide two or even more lifting arms on the carrying device 9, which together form a fork supported on the main carriage 7 via the carrying device 9.
  • the lifting arm 10 when a load to be picked up by the lifting arm 10 is adjacent to the transfer device, the lifting arm 10 is displaceable in the vertical direction relative to the load by means of the carrying device 9 in order to allow, as explained below, the lifting arm 10 to be inserted into the cavity of the load and then the Lift the load off the floor with the lifting arm 10.
  • the support device 9 for the lifting arm 10 does not have to be displaceable in the vertical direction, because it is then the load which is relative to the floor in FIG vertical direction, for example, with the aid of drive means, not shown, such as electric or hydraulic motors or hydraulic or pneumatic cylinders, in order to further allow the lifting arm 10 to be inserted into the cavity of the load and then to lift the load off the floor with the lifting arm 10.
  • the lifting and / or lowering of the load with the aid of the lifting arm 10 essentially depends on the lifting arm and the load being displaceable in the vertical direction relative to one another.

  • drive means not shown, such as electric or hydraulic motors or hydraulic or pneumatic cylinders
  • the supports 12 In their retracted or swiveled-in position, the supports 12 are lifted off the floor, thus allowing the chassis to be driven on a roadway. In its extended or pivoted-out position, one end part 13 is one Support 12 supported on the ground to support the chassis 1 laterally on the road. Thus, the tipping moment of the load around the contact point of the wheels 4 with the road on the side in question is compensated for when the load is lifted from the floor with the lifting arm 10 after the lifting arm 10 has been inserted into the cavity of the load.
  • the chassis 1 is first moved towards the load so that a long side of the chassis 1 comes to rest next to the load, the cavity of the load being oriented essentially at right angles to the longitudinal direction of the chassis 1.
