Definitions

  • the present invention relates to a load lifting device according to the preamble of patent claim 1.
  • the transport crossbar is attached to the part to be lifted by means of a screw connection.
  • This type of installation requires three to four men.
  • the thread of the bolts to be screwed in has very often been damaged in such devices.
  • the object of the invention is to provide a load lifting device which ensures simple attachment of the load lifting device to the heavy part to be lifted and a lower risk of damage to the elements of the device.
  • a transport crossbar 1 of the load lifting device is connected directly to a coupling device 2 designed as a quick coupling.
  • the coupling device 2 has a mushroom-shaped holding element 4 which can be attached to a printing unit 3 and an essentially bell-shaped gripping element 5 which is fastened to the transport crossbar 1.
  • the gripping element 5 is designed as a hollow cylinder which is slightly widened at one end and merges into a bolt-shaped, preferably threaded element 16 at its other end, which represents a wall 6 of the bell-shaped gripping element 5.
  • the wall 6 is enclosed by an axially displaceable clamping sleeve 7.
  • holes 8 are made radially in the circumferential direction and are provided for receiving a locking ball 9 in each case.
  • the bores 8 on the inside of the wall 6 are each provided with an edge that slightly reduces the clear width of the bores 8 so that the locking balls 9 cannot fall through the bores 8 into the interior of the bell-shaped gripping element 5.
  • the locking balls 9 are secured by the clamping sleeve 7, which forms a locking device together with the bores 8 and the locking balls 9.
  • spring elements can be inserted into the bores 8, by means of which the balls 9 are pressed into the recess provided in the clamping sleeve 7 when the clamping sleeve 7 is in its upper position.
  • the mushroom-shaped holding elements 4 are designed as screw bolts and have a head part 10, a shaft 11 and a base 12.
  • the head part 10 has a substantially larger diameter than the shaft 11 and is designed on its outside, ie on the surface facing away from the base 12, as a truncated cone with a conical ring surface 13.
  • the side of the head part 10 facing the base 12 is designed as a conical ring surface 14.
  • the base 12 is designed as a hexagon on its circumference and merges into a threaded bolt 15 on the side facing away from the head part 10.
  • the head part 10 can also be cylindrical on its outside if the bores 8 of the gripping elements 5 are provided with spring elements in the manner described above.
  • the wall 6 has on its outer surface a locking channel 18 shown in detail in FIG. 3, which consists of a partial channel 181 running parallel to the axis of rotation of the wall 6, a partial channel 182 running at right angles thereto and a subchannel 183 parallel to the subchannel 181 and directed from the subchannel 182 toward the widened end of the gripping element 5 is formed.
  • the clamping sleeve 7 On its end facing the bolt-shaped element 16, the clamping sleeve 7 has a threaded pin 17 which projects into the interior of the clamping sleeve 7. This grub screw 17 is e.g.
  • the set screw 17 and the locking channel 18 together form a locking device according to the principle of a bayonet lock.
  • the wall 6 has on the cylindrical section of its outer surface a securing groove 21 which is made in the circumferential direction and is made close to the widened end of the wall 6. This is functionally assigned to a securing bore 20 introduced into the clamping sleeve 7.
  • a groove 191 is introduced in the circumferential direction, into which a retaining ring 19 is inserted.
  • the holding elements 4 are screwed into the respective upper surface of the side walls thereof during the assembly of the printing unit and remain there until the printing unit is installed at the operating location.
  • the transport crossbar 1 When attaching and attaching the transport device to a printing unit to be lifted and transported, the transport crossbar 1 is brought into such a position that each of the bell-shaped gripping elements 5 is held by an associated holding element 4.
  • the clamping sleeve 7 of each of the gripping elements 5 is in an upper position, and the locking balls 9 do not protrude into the interior of the gripping elements 5.
  • the gripping elements 5 are slipped onto the holding elements 4 by lowering the transport crossbar 1.
  • the clamping sleeve 7 is pushed down on each coupling device 2, whereby the locking balls 9 are pushed so far into the interior of the gripping elements 5 that the holding elements 4 are fixed inside the gripping elements 5.
  • the clamping sleeve 7 is in its lower position by means of a securing element which is guided through the securing bore 20 and engages in the securing groove 21, e.g. a spring pin, secured against slipping up.
  • the securing element is first removed and then the clamping sleeve 7 is pushed upwards.
  • the gripping element 5 is raised, the conical ring surface 14 of the holding element 4 causes the locking balls 9 to enter the wall 6 to such an extent that the gripping element 5 can be separated from the holding element 4.
  • the number of locking balls 9 arranged in the gripping element 5 is determined by the size of the coupling device 2 and its load-bearing capacity. In the embodiment shown in FIG. 1, eight balls are arranged at the same distance from one another in the wall 6.
  • the load capacity of the coupling device shown is 20,000 kg.
  • FIG. 2 shows the load lifting device according to the invention in the embodiment shown in FIG. 1 with a locked coupling device 2.
  • the geometry of the head part 10 prevents the clamping sleeve 7 from being pushed up under load by the fact that the attached load by means of the conical ring surface 14 is converted into a force introduced obliquely into the balls 9 with respect to the axis of the holding element 4, the radial component of which clamps the clamping sleeve 7.
