Definitions

  • the invention relates to a receiving device for placing a sling on a distribution boom, the sling being designed to lift and transport the distribution boom.
  • the invention also relates to a distribution boom with a receiving device for a sling which is designed to lift and transport the distribution boom.
  • a distribution boom consisting of several mast segments, which can usually be used on construction sites for the spreading of concrete, but also for other applications, for example for the distribution of biomass or liquids in a field, is usually carried by a crane with suitable slinging equipment, For example, two or more steel cables, chains or nylon cables or straps or similar suitable slinging devices are raised and bolted to a partial segment of a mast segment or, if the entire distribution boom is raised with a turntable, mounted on a substructure, for example a support column or a lattice tower.
  • the folded mast package of a distribution boom can also, as for example in the patent application DE 10 2012 224 529 A1 described, can be hung on the turntable of the distribution boom.
  • the placing boom or the folded mast package of the placing boom lifted by a crane by means of two or more slings, which are at the end of the turntable side (foot part) of the first mast segment and the end of the first mast segment (head part) facing away from the turntable provided anchor points.
  • a work platform for assembling the placing boom in order to connect the concrete delivery line, hydraulic lines, if necessary other mast segments of the mast package, etc. for the working operation of the placing boom after the mast package has been assembled.
  • the slinging equipment with which the folded mast package was lifted must be removed for work operations.
  • the problem here is that the sling, which is attached to the outer end of the mast package for transport, is not accessible or is very difficult to reach and therefore cannot be easily unhooked.
  • the slinging device can be easily unhooked and removed in the area of the turntable, where the work platform is located.
  • the sling means that is suspended in the area of the work platform is first removed.
  • the slinging equipment, which is attached to the far end of the mast package, is simply placed on the distribution mast and remains attached to the inaccessible attachment point.
  • it can also be removed in a complex manner, for example using a personnel basket suspended from the crane.
  • the slinging device If the slinging device remains loose on the mast package, it can damage the surfaces of the mast segments, in particular the first mast segment, or one end can fall due to the movements of the placing boom during operation.
  • the loose end of the sling cannot easily be hooked into the area of the turntable or rigidly fastened because the mast segment bends during operation. This means that the slinging gear would have to be hooked or put down loosely so that it can continue to slide back and forth on the mast segments and damage the surfaces there.
  • This task is solved by a receiving device for placing a sling on a distribution boom with the features of claim 1 and a distribution boom with a corresponding device according to claim 8.
  • variable length mount is to be understood as meaning that at least one supporting end of the sling means is placed movably in the longitudinal direction in relation to the mast segment of the distribution boom on which the sling means is placed.
  • the sling with the first supporting end on the distribution boom remains hooked to a stop point after the distribution mast has been transported and the receiving device is designed to accommodate the second supporting end of the sling in a variable-length manner.
  • the sling means is designed as a support rod.
  • a support rod is rigid and can easily be placed on the receiving device with at least one supporting end without the rod sagging significantly and thus touching the surface of the distribution boom during operation and thus causing damage there .
  • the receiving device advantageously has a storage surface which is designed for the length-variable storage of the second end of the sling means.
  • a storage surface on which the second end of the sling is placed the support rod does not rest directly on the distribution boom and can therefore not cause any damage to the distribution boom.
  • the storage area allows the support rod to be placed at a certain distance from the surface of the distribution boom, so that the support rod, even if it sags slightly, cannot touch the surface of the distribution boom and therefore cannot damage it.
  • the receiving device advantageously has lateral guides which are designed to laterally guide the second end of the support rod.
  • the side guides prevent the support rod from slipping laterally from the support surface onto the surface of the distribution boom and thus causing damage there.
  • the receiving device advantageously has means which are designed to secure the second end of the support rod on the receiving device. These securing means prevent the second end of the support rod from detaching from the receiving device, even when the distribution boom moves up and down more quickly or when the distribution boom is moved into a vertical position, for example.
  • the sling means is flexible, for example a support cable or a chain
  • the receiving device is designed as a tensioning device which is designed to accommodate the second end of the sling means in a variable length.
  • the tensioning device ensures length compensation during operation of the distribution boom, so that the slinging device is held with almost constant tension and at a certain distance from the surface of the distribution mast and a deflection of the distribution mast does not lead to overstretching of the slinging device.
  • the invention is further characterized by a distribution boom with a receiving device for storing a sling, the sling being used for Lifting and transporting the distribution boom is designed and has two ends and remains hooked to the distribution boom with a first of the two ends after transport, the receiving device being designed to accommodate the second end of the sling means in a variable-length manner.

  • the turntable 3 is rotatably connected to the support column 4 via a turntable 7.
  • a partial segment 10a of the first mast segment 10 is connected to the turntable 3 via a swivel joint 6.
  • a work platform 5 with a railing is arranged.
  • the second assembly complex of the distribution mast 1 consists of the folded mast package 2.
  • the mast package 2 consists of the first partial mast segment 10b, the second mast segment 11 and the third mast segment 12 and possibly further mast segments, not shown in the figure, each of which has articulated joints 14, 15 are pivotally connected to one another.
  • the first mast segment 10 is pivoted relative to the turntable 3 and the mast segments 10, 11, 12 are pivoted towards each other via joint drives (not shown), for example hydraulic cylinders.
  • the mast package 2 can consist of more or fewer mast segments 10, 11, 12 that are pivotally connected to one another.
  • a delivery line is arranged through or along the support column 4, which leads through or along the turntable 3 to the mast package 2 and there along the mast segments 10, 11, 12 to the top of the mast, there via an end hose, not shown, in working operation with the unfolded mast Apply fresh concrete or other thick materials or liquids.
  • two stop points 23a and 23b for sling means 20 and 21 for lifting and transporting the mast package 2 of the distribution boom 1 are arranged on the top of the first partial mast segment 10 or in another type of folding of the mast package 2 not shown here.
  • the attachment point 23a is located on the head part of the first mast segment 10 relatively far away from the turntable 6 with the work platform 5.
  • the sling 21 is suspended with its first supporting end 21b on the sling point 23a.
  • the sling 21 is suspended with its second supporting end 21a on a crane hook 22.
  • Another sling 20 is suspended with the first supporting end 20b on the second anchor point 23b and with its second supporting end 20a on the crane hook 22.
  • the mast package 2 can be moved to the already assembled turntable 6 using a crane. Then the two partial mast segments 10a and 10b are guided towards each other so that they can be bolted together via the bolt connection 13.
  • the second supporting end 21b of the sling means 21 cannot be reached by a fitter from the work platform 5, which is why this supporting end 21b remains attached to the anchor point 23a after assembly.
  • the Figure 2 shows an assembly variant in which the mast package 2 is lifted together with the turntable 6 and transported onto the support column 4.
  • This variant is preferred, for example, if a crane is available that can lift a larger load. In this way, the bolt connection 13 of the partial mast segments 10a and 10b can be made before lifting on the ground.
  • a third anchor point 23c is used on the partial mast segment 10a or on the turntable for the sling 20, whereby the mast package 2 with the turntable 3 can be better balanced on the crane hook 22 during transport.
  • the length of the sling 20 can be changed, for example, or sling 20 with different lengths are used for the two transport variants. As already in connection with the Figure 1 explained, remains after the assembly of the Distribution boom 1, the sling 21 is suspended with the first supporting end 21b at the stop point 23a.
