Definitions

  • the invention relates to an extendable weight compensation device according to the preamble of claim 1.
  • Such a pull-out weight compensation device is known from DE-C-728 400.
  • it is possible to absorb reaction torques at a specific position of the tool axis of rotation, but a constant height adjustment cannot be achieved during operation of the tool, since the parts of the suspension remain telescopically displaceable relative to one another even during tool operation.
  • the object of the invention is to improve the known weight compensation device with regard to its height adjustment during operation in such a way that the tool can be locked at an arbitrarily selectable height.
  • the configuration of claim 4 gives a piston-cylinder arrangement in which the piston rod can be replaced.
  • piston rods with different diameters can be used in constant piston-cylinder arrangements.
  • the ratio of the inner cylinder diameter to the piston diameter and thus the load-bearing capacity of the weight balancer can be adjusted with simple means. This also ensures easy maintenance.
  • From US-PS 33 26 546 a similar hydropneumatic piston cylinder arrangement with inner cylinder and outer cylinder is known, but in the known arrangement the interchangeability of the piston rod and thus the possibility of adjusting the load capacity of the weight balancer is not available.
  • the setting option is supported by the configurations of subclaims 5 to 7.
  • the configuration of claim 9 provides a compact arrangement of the individual components of the weight balancer.
  • the configuration of claim 21 results in control of the commissioning of the tool in such a way that the tool itself is only put into operation when all the operating conditions necessary to absorb the forces exerted by the tool have been created.
  • the weight balancer according to the invention can be used practically wherever hand-operated tools are used.
  • the invention largely avoids physical exertion which must be expended by the operating personnel in conventional devices.
  • Fig. 1 shows an embodiment of the invention, in which a tension tube 1 with a circular cross section ver as rigid support is used, which can be positively connected with the help of a collet 3 with an outer cylinder 4 of a piston-cylinder arrangement.

  • the tool 9 Via a fastening rod 8, the tool 9 is rigidly fastened to the outer cylinder 4 of the piston-cylinder arrangement with the aid of a fixed connection 10.
  • the outer cylinder 4 of the piston-cylinder arrangement arranged in the clamping tube 1 is pulled downwards or raised upwards.
  • the effective load capacities or spring forces remain essentially constant over the entire extension length or lifting height.
  • the collet 3 is tightened by corresponding actuation of a valve 11, which is connected to a pressure source via a port P, so that the clamping tube 1 is rigid with the outer cylinder 4 is connected.
  • the height setting of the tool 9 is thus fixed.
  • the pressure medium is introduced through the valve 11, which also has the pressure medium outlet A, into the collet via a pressure line 12.
  • Pressure medium is also conveyed through the pressure line 12 to the pneumatically actuated locking device 6 of the trolley 5, so that the clamping jaws are placed on the rail 7 and the trolley 5 is blocked.
  • the tool 9 is then put into operation by further actuation of the valve 11 in the same direction.
  • a hand lever 13 is used, through which a valve piston 14, which will be explained in more detail in connection with FIGS. 6 and 7, is inserted into the valve for actuating the collet 3 and the clamping device 6 and the tool 9.
  • the devices mentioned are then operated in the order described above.
  • FIG. 2 An exemplary embodiment is described in FIG. 2, in which the weight compensation device is arranged on a carriage 30 which can be moved on the floor. This is mounted over the tensioning tube 1 "in such a way that it can be pivoted through 360 °.
  • a lockable cylinder arrangement 22 serves as storage, by means of which the weight balancer can be pivoted together with the tool into the corresponding operating position.
