Definitions

  • the invention relates to a mobile crane with a telescopic boom according to the Preamble of claim 1.
  • DE 39 34 783 A1 discloses a crane which has a jib arm which in turn consists of several articulated sections.
  • the proposed crane is to be used as a multi-purpose crane, but not as a city crane only for lifting objects such as B. of steel beams, but at the same time is used to support the construction work.
  • the main elements of this Cranes are a base frame, a drive part for driving and controlling the crane, which is rotatable on the base frame in a horizontal plane, one on the Drive part attached articulated arm, which is in a vertical plane can be folded up and stretched out, a gripping device for gripping of construction elements, the gripping device being tiltable and removable with the front end of the arm is connected.
  • a generic crane is disclosed in DE 29 50 884 A1.
  • This has one Telescopic boom, which consists of a basic box and several by means of one Telescopic device retractable and extendable telescopic sections.
  • the Telescopic shots can be swiveled in the direction of the boom Basic box connected.
  • the piston-cylinder unit is arranged on the underside of the boom, and in such a way that the cylinder is articulated on the underside of the basic box and the Piston rod is attached to a corner point of the angle insert.
  • the second The corner point of the angle insert is the one after the kink Telescopic shot connected while the hinge of the angle insert on the head of the Basic box is arranged.
  • a disadvantage of this arrangement is that it only has small interfering edge heights can be bridged, as this is essentially due to the length of the basic box is determined.
  • Telescopic boom is a movable in the innermost telescopic section Extension piece arranged around in its fully extended longitudinal position the link from the to the longitudinal direction of the innermost telescopic shot aligned position pivotable and in relation to this in predetermined Swivel positions can be determined by means of a bolt.
  • the bolt forms a stop.
  • the arrangement of the Extension piece is in the head part of the innermost telescopic shot Opening and in the foot part of the extension piece several on one Circular arc provided recesses arranged around the connecting member. In the bolt engages these recesses in the pivoting position of the extension piece on.
  • a disadvantage of this arrangement is the need to break through the head part of the innermost telescopic shot, so that the roller head design and the rope guide is difficult.
  • Another disadvantage is that the longitudinal extension of the Extension piece is limited and the angle only in discrete degrees is possible.
  • the object of the invention is a generic mobile crane with a Specify telescopic boom with which in a simple manner with sufficient Horizontal extent a large interfering edge height can be bridged.
  • the essence of the invention is that at least the innermost telescopic section is pivotable and then at least a non-kinked telescopic shot is connected to the rear and the hinge of the kink on the bottom and the adjustment mechanism are arranged on the top of the boom.
  • the kink is based on the included angle preferably in a range of 90 ° to 180 °.
  • the adjustment mechanism can be of various types, for example one Rope construction, a rack, a spindle, two meshing ones Gears or a piston-cylinder unit. The latter means has proven to be has been found to be advantageous, although it is expensive and has a relatively high weight.
  • the kink is provided in the closed position by means of to secure a bolt attached to a piston-cylinder unit, this crosswise is arranged to the longitudinal axis of the boom.
  • the kink can be placed on different slopes within the boom length be, it has proven to be advantageous if the before the kink the length of the boom is twice as long as that after the kink Boom length.
  • FIG 1 is a longitudinal view of a mobile crane designed according to the invention 1 shown with telescopic boom.
  • the main construction groups are an undercarriage 2 a total of five axles 3 - 7 and an upper carriage 8 rotatably arranged thereon.
  • This main boom 12 consists of a basic box 13 and five telescopic sections 14-18 that can be telescoped therein, of which three 14-16 before a kink 19 and two 17, 18 after the kink 19 are arranged.
  • a Roller head 20 At the front end of the innermost telescopic section 19 is a Roller head 20 arranged.
  • an adapter 21 for Recording of the two inner telescopic sections 17, 18 provided.
  • Figures 2 and 3 show the essential possibilities with the invention trained boom system can be realized.
  • Step shows telescoping of the telescopic section 17 arranged immediately after the kink point 19 telescoped shot 18 and the kinking to accommodate a load 22 to be able to.
  • the step shows that after lifting the boom 13 after the kink 19 arranged telescopic sections 17, 18 continuously, here in the Horizontal can be telescoped.
  • the step shows that the Telescopic sections 14 - 16 can be telescoped continuously in front of the kink 19 can.
  • the angle in the kink 19 can be stepless regardless be adjusted.
  • the last step shows moving the load 22 straight Boom with a secured break point 19.
  • FIGS. 4-8 show the details of the formation of the kink 19 4, the kink 19 in the closed state and FIG. 5 the kink 19 in the open, d. H. shows in the bent state.
  • a joint 26 has the outer end region of the front of the kink 19 lying telescopic section 16 a collar-like frame part 27 and that after Bending point 19 lying adapter piece 21 is also a collar-shaped Frame part 28 on.
  • Piston-cylinder unit 29 and a rope pulley 31 guiding the load rope 30 are attached.
  • Figure 6 shows a plan view of the kink 19 and Figure 7,8 each a section in Figure 6.
  • the frame part 27 Bearing block 34, 34 'is provided, through which a bolt 35 can be inserted. So that Load rope 30 in the closed position ( Figure 4) without interference across the area the piston-cylinder unit 29 can be guided is in the upper end region of the Frame part 28 attached an attachment 36 on which a roller 37 is rotatably arranged is.
  • Piston-cylinder unit 45 is arranged, on which a bolt 48 is fastened (FIG. 8). In the In the open position, the piston together with the pin 48 is moved to the right and up this way the kink 19 is released.
  • section AA In section AA according to FIG. 7 it can be seen that the upper region of the frame part 27 is fastened by means of a weld seam 38 to the telescopic section 16 lying in front of the kink 19.
  • Two blocks 39, 39 ', 40, 40' are arranged in the lower region of the frame part 27 in order to form the joint 26.
  • the bolts 39, 39 ', 40, 40' act together with webs 41, 42 of the frame part 28 and bolts 43, 44 extending through the trestles 39, 39 ', 40, 40' and the webs 41, 42.
