Turning device for prestressed concrete products

The invention relates to a turning device for prestressed concrete products of great length and relates in particular to such a _{device 9} with which T-beams can be brought into the required transport position for removal _{or the like}

Due to the prestressing, prestressed concrete products show a stitch after inspection _p the size of which depends not only on the prestressing but also on the length of the product _o So are relatively long

Prestressed concrete products under strong spans and need to daherj prevent a possible risk of fracture in the bending apex, be turned to production for transportation to 180® ₀ At large, often weighing several tons prestressed concrete products, this is ver with a very considerable expenditure on equipment ~

bunden _e In particular, however, the risk of breaking these _{Spannbetönerseugniese is relatively large 9} because when turning from the tension image of the cantilever arm through the central support of the element in which the single-span panels must be changed ο

The invention is based on the object _g is a turning device for prestressed concrete products to create, for example, U-Trägerp can be rotated without mn by resulting in elements inside voltage alternating break "by 180 ° with the very long prestressed concrete elements _{9 o}

According to the invention, this is in a turning device for prestressed concrete products of great length by at least two opposing, laterally offset, pivotably mounted angular support elements _9, where two of the support side and the other two support elements opposite this form the removal side ^ possible

On the acceptance side are in the area of the ends of the elements at least two angularly designed support elements are provided in order to be able to take over elements of different lengths in their pivot axis relative to one another are movable *

The support elements are expediently designed at right angles and are rotatably mounted in their apex _{or the like}

The invention is based on the drawing in which a guide = example of this is illustrated, illustrated in more detail,

The operation of the device is as follows

Prestressed concrete * = products that have been stacked in the finished position until after production are gripped in the middle by a known crane gripper and Zmr placed on the supporting elements -1 on the support side, largely gentle treatment of the prestressed concrete products placed in each case, the supporting elements with appropriate insulation materials ₉ % _O B _O HoIa or plastic uswo spanned To turn the IT carrier 5 lying on the support side on the cheek, torch the centrally arranged pressure cylinders 9 over the piston rods 11 and the reversing levers 13 _P the two support elements 2 on the removal side each in their vertices 4 in direction of the arrow C as turned 90 ° ₉ so that one of _s in Ausgangelage the supporting element pairs to these against one another turned-open angle parts * now to the other faces, and which is originally directed respectively in Tertikaler bEEN Winkelsohenkel position now horizontally to the receiving side _9! igο 2 " Now pan ^ f The support elements 1 of the support side with the placed IT support are actuated by the lifting cylinders 8 ^ via the piston rods 10 and the pivoting levers 12 at their vertices 3 in the direction of the arrow D by 90 ° around ₉ so that the angled legs of all support elements 1, which are upright in the starting position "2 now horizontally in transfer position III. are ^ where now the Tertikai standing facing the receiving side angle leg of the load-bearing elements 2 on the ends of the ~ to be acquired U carrier press _o In this tJbergabelage are open Winkelteile..zueinander ^ directed so that the.
