Definitions

  • the invention relates to a lock for telescopic shots according to the preamble of Claim 1.
  • Telescopic shots from crane booms can be locked when extended, to relieve the telescopic system, among other things. This applies in particular if Driver devices, for example piston / cylinder units for extending the telescopic shots are used, which extend one telescope shot after the other or retract.
  • Driver devices for example piston / cylinder units for extending the telescopic shots are used, which extend one telescope shot after the other or retract.
  • locking bolts are usually used, that from a telescopic shot into a recording of an adjacent telescopic shot intervention.
  • a locking system is known from DE 198 11 813 A1, in which two locking bolts each a locking unit on the inner telescopic section are arranged so that them with two opposing shots in the vertical side bridges of the adjacent outer telescopic section can be brought into engagement.
  • the lock points a hydraulic cylinder which is arranged parallel to the longitudinal axis of the telescopic sections and a lever on the direction of movement of the actuating cylinder in the movement the locking bolt moves. The engaging end of the lever engages when the device controlled by position monitoring is driven to the appropriate place, in the inner grip of the locking cylinder so that by actuating the hydraulic cylinder the locked position can be released.
  • a lock for telescopic shots comprises a linearly displaceable Locking bolt for connecting and detaching an inner telescopic shot and an outer telescopic shot, the locking bolt by means of a rotary actuation is moved from its extended position to its retracted position and is held biased in its extended position.
  • the advantage of the arrangement according to the invention is in particular that it can be used very small overall dimensions. So that the locking system can be essential smaller telescopic sections of crane jibs can be used than before. Either the height and the width of the required installation space are determined by the use one turn operation noticeably reduced.
  • the locking bolt is preferably mounted and protrudes in the inner telescopic section in its extended position into the adjoining outer telescopic section, so that the telescopic sections are not displaced in the axial direction relative to one another can. In its retracted position, the locking bolt is out of engagement with the outer telescopic section, with a displacement of the telescopic sections relative to each other is made possible.
  • It can be a small compared to a hydraulic cylinder
  • Rotary drive can be used. This rotary drive can either be hydraulic or electrical or operated pneumatically. Such a rotary drive takes up less space as a hydraulic cylinder, which is attached to the locking bolt by means of a lever system works.
  • Two locking bolts on the inner telescopic section are particularly preferred arranged in such a way that with two opposing pictures in the vertical side bars of the outer telescopic section can be engaged, namely preferably in the middle of the side bars.
  • the rotary actuation can act directly on the locking bolt.

Particularly preferably, the curve guidance can only be disengaged be brought with the locking bolt when the locking bolt is in its extended position. This increases the operational security of a lock, because the inner telescopic shot is never in a "free" state in which the inner Telescopic shot neither connected to the outer telescopic shot nor to the curve guide is. Preferably, the curve guide can then be locked in with the locking bolt or be disengaged when the locking bolt is in its "safe" extended position.
  • the curve guide can preferably be brought into a passive position in which the Is out of engagement with the locking pin and relative to the locking pin can be moved without engaging with the locking bolt reach.
