Definitions
- the invention relates to a crane with a telescopic boom according to the preamble of claim 1.
- the driver device consists of a hydraulic block with each other opposite cylinders for the one and formed by their pistons extendable bolt locking the respective shot and one perpendicular to it arranged hydraulic piston-cylinder unit for actuating the respective Locking bolt.
- the hydraulic elements of the driver device are in place so in operative connection that the radial piston-cylinder unit for retracting the respective locking bolt can only be operated if the Driver device with the out or bag-telescopic shot over the locking bolt is coupled.
- a comparable telescopic system is known from EP 0 754 646 A1. It consists of a basic shot and at least two against the basic shot telescopic shots. The shots are in their respective positions to each other releasable socket bolts penetrating through the walls of adjacent shots (Locking bolt) fixed.
- the telescopic system also has one of the Shots limited, preferably single-stage with pressure medium on both sides loadable lifting cylinder. This lifting cylinder is provided with drivers, which can be brought into active engagement with the shot to be relocated in each case.
- the piston rod is the Piston cylinder unit hinged to the inner end of the outer shot.
- DE 31 25 603 A1 discloses a telescopic boom with a basic boom and three telescopic shots, which are directly or indirectly via chain drives by means of a single-stage piston-cylinder unit are retractable and extendable.
- the cylinder housing of the Piston cylinder unit is at its rear end at the inner end of the Articulated boom.
- the piston rod is at the front end via a bolt connected to a cylinder case that includes the extended piston rod, the near its inner end with a bolt to the side walls of the first telescopic shot is connected.
- the disadvantage of this construction is that all three telescopic shots can only be retracted and extended together and one targeted retraction and extension of only one telescopic shot is not possible.
- the object of the invention is to provide a crane with a telescopic boom, the while maintaining the principle of individual telescoping of the shots by means of a piston-cylinder unit is inexpensive to manufacture and compared to known prior art enables a higher telescopic speed and whose usable load is higher.
- each a fuse and Locking unit attached with recesses of the telescopic Shots can be detached.
- the displaceable element of the piston-cylinder unit can optionally be the cylinder housing, in this case the piston rod with your articulated rear end to the inner end of the basic boom - or the Piston rod - in this case the cylinder housing is at its rear end articulated inner end of the basic boom. In both cases it is advantageous that by the arrangement of two securing and locking units the length of the Piston cylinder unit is only about 50% of the length of the main boom.
- a shorter piston-cylinder unit means a shorter kink length, so that the Piston-cylinder unit designed dimensionally cheaper with the same lifting force can be. This in turn has a direct impact on the weight, which despite the Additional weight through the arrangement of the second safety and Locking unit is lower compared to a 100% length.
- the arrangement with an am is preferred Basic boom hinged cylinder housing selected, in which the piston rod with a guiding and pulling device parallel to the piston-cylinder unit is connected, at the inner and outer ends of the two safety and Locking units are attached.
- the guiding and pulling device consists of a cross member attached to the front end of the piston rod, and two each guide elements lying on the right and left of the cylinder housing.
- the front one The end of the guide elements is with the cross bar on the one hand and the front one End area of the guide elements with the second securing and Locking unit on the other hand and the rear ends with the first securing and Locking unit connected.
- the cross member preferably has a Web plate stiffened flat profile and the guide elements consist of Box profiles with internal sheet metal stiffeners.
- the securing and locking unit arranged at the inner end has one on the cylinder housing of the piston-cylinder unit sliding bushing with is connected to the two guide elements.
- This socket is slidable Sliding piece arranged mechanically via guide grooves and guide rings is in operative connection with the two safety bolts and the gripper.
- the Arrangement of guide grooves and guide rings is chosen so that a Pulling the respective locking bolt is only possible if the two Safety bolts in the respective lateral recesses of the telescopic sections are retracted and vice versa the two safety bolts are pulled out the respective recesses is only possible if the respective locking bolt is set.
- the actuating element for the sliding piece is preferably one with the piston-cylinder unit connected to the guide elements.
- This Piston-cylinder unit is parallel to the cylinder housing of the shots moving piston-cylinder unit arranged.
- locking and locking unit can be arranged on the arrangement Socket be dispensed with.
- the other elements are congruent.
- To put the locking bolt have the shots except those on the inside and outside Recesses provided at the end also in the central area. These additional recesses are preferably approximately 50% of the length of the Shots arranged one above the other. This means that for an input or Slide out about 50% of the length of the latch over the one at the inner end arranged locking and locking unit and for further engagement or Slide out between 50-100% the latch over at the outer end arranged locking and locking unit takes place.
- a known piston-cylinder unit has the advantage that it is inexpensive is producible and good guidance in terms of security and Has locking unit.
- the oil supply to the Piston cylinder unit facilitated by the fact that the bottom oil supply directly on End of the basic boom can be realized with the cylinder housing.
- the amount of oil in the cylinder housing with hydraulic connections the have a large nominal diameter, without turbulence, in the shortest possible way into the Hydraulic tank are returned, which increases the speed at Telescopic operation is beneficial.
- the center of gravity of the extended The main boom moves due to the weight of the hydraulic oil Cylinder after the main boom base, which is a reduction in Main boom head weight and thus an increase in payload.
- Advantageous is also the mechanical interlock that is unaffected by electrical or hydraulic disturbances.
- FIGS. 1a, b and 2a, b are in one with an oval cross section equipped basic boom 1 several telescopic sections 2 - 5 inserted into each other axially displaceable.
- a unit is a telescopic boom for stationary or mobile cranes can be used.
- telescopic shots 2 - 5 are carried out by means of a device known single-stage piston-cylinder unit.
- the piston rod 16 (FIG. 2b) is not the embodiment, but the cylinder housing 6 on the extension arm 18 that closes the basic boom 1 by means of a bearing 7 articulated.
- Telescopic shot 2-5 has a recess 2B, 2B '- 5B, 5B' on each side. In this recess is by means of the safety and Locking unit 8.1, a securing bolt 13, 13 'can be inserted.
- a guide element 9, 9 ' is arranged, which on the front End are connected via a cross member 11 stiffened with a web plate 30. to A support roller 12 is attached in the area of the cross member 11.
- Figure 3 shows a perspective view of the details of the interior End arranged locking and locking unit 8.1. It consists of one slidably arranged on the cylinder housing 6 of the piston-cylinder unit Bushing 28, which is connected to the end regions of the guide elements 9, 9 '. The Connection is via bolts 26.1, 26.2 - 26.1 ", 26.2" ( Figure 2a, b).
- a sliding piece 21 is slidably arranged on the jack 28, a sliding piece 21 is slidably arranged. The shift takes place via a piston-cylinder unit 14 lying parallel to the cylinder housing 6, which in turn is firmly connected to the socket 28.
- the sliding piece 21 is on the right and left a web plate 29, 29 'lying in the horizontal plane is arranged, which with a Guide groove 27, 27 'is provided.
- This guide groove 27, 27 ' cooperates with a guide ring 22, 22 'connected to the respective securing bolt 13, 13' ( Figure 4, 5).
- the two opposing securing bolts 13, 13 ' are retractable and extendable into the respective lateral recesses 2B, 2B '- 5B, 5B' ( Figure 4, 5).
