Definitions

  • the invention relates to a transport pallet truck for heavy loads, in particular for converter changeable vessels of steel production, with a moving frame that can be rotated relative to a rotating frame when converted into different directions of travel, and with a lifting frame that can be raised and lowered relative to the moving frame by means of a pressure medium cylinder.
  • a transport pallet truck of this type is known from DE-A No. 2725123.
  • the converter change vessel is supported on a lifting frame which is articulated via tension members or pressure medium cylinders to a crosshead which can be raised and lowered relative to the traveling frame, which requires a complex and not very stable construction.
  • the rotating frame is rotatably mounted on the traveling frame independently of the lifting frame and must be supported against the ground by means of its own pressure medium cylinder when the vehicle is moved at a rail crossing.
  • the converter vessel can be supported on the lifting frame itself by means of short-stroke piston-cylinder units, which enable the vessel to be adapted to its holder. However, these piston-cylinder units do not allow the vessel to be raised or lowered.
  • a transport pallet truck is also known from DE-C No. 2407073, in which several concentric rotating frames are provided within the traveling frame, which are supported on the traveling frame in certain angular positions and can pass through the frame in other angular positions. Retractable and retractable lifting elements with a smaller lifting height than the entire lifting path of the load are arranged on the rotating frame.
  • the converter rests on a plate connected to an upper rotating frame; the lifting or lowering takes place in several steps, each with locking means, e.g. hydraulic cylinders are provided to hold the converter between the adjustment steps at a certain height. This requires precise control, which makes the setup complex.
  • the invention aims at avoiding these difficulties and has as its object to provide a robust, structurally simple transport pallet truck in which large lifting heights can be achieved without using telescopic cylinders and without having to carry out the lifting in several steps. Furthermore, it should be possible to move the transport pallet truck at intersections without providing its own pressure medium cylinders.
  • the transport lift truck is particularly stable when the pressure medium cylinder acts upwards or downwards on a one-piece rigid lifting frame.
  • the rotatable mounting of the rotating frame on the lifting frame means that the transport pallet truck can be implemented at a rail crossing by actuating the pressure medium cylinders supporting the lifting frame on the moving frame, as a result of which no separate pressure medium cylinders have to be provided for this purpose.
  • the rotating frame is mounted on the underside of the lifting frame by means of a bearing which absorbs compressive forces and can be supported directly on the floor.
  • FIG. 1 shows a side view in the lowered position of the converter
  • FIG. 2 in the raised position of the converter, partly in section.
  • Fig. 3 shows a floor plan
  • Fig. 4 is a side view in the raised position of the traveling frame with the converter lowered.
  • the pistons 6 and 15 of the hydraulic lifting means which can be pushed out in the opposite direction, achieve a large lifting height in a simple manner without expensive locking and control measures being necessary, and the stability as a result of the mounting of the converter claws on the piston ends, compared with the known devices , is improved, u. This is because the center of gravity of the converter is approximately at the level of the support.
