- the present invention relates to a turning device for turning profile beams, especially for mounting on an excavator or the like.
- the present invention seeks to remedy this. It is based on the task to create a turning device for turning profile beams, the one quick, safe and damage-free handling of the profile beams when turning allowed.
- the turning device for turning profile beams therefore has a base frame, a profile rack, which is about an approximately horizontal pivot axis is pivotally mounted on the base frame, and a pivoting device for swiveling the profile support shelf.
- the profile beam is first brought the profile rack into its initial position, so that one Excavator or the like gripped profile carrier with its flat side or a corresponding pre-stacked beam bundles are placed on the beam rack can.
- the profile support tray is preferred about its horizontal pivot axis pivoted about 90 ° so that the profile beams are turned.
- the profile supports can or the profile beam bundle raised again by the excavator or the like become.
- the swivel device works gravity operated, i.e. the profile rack is determined by the weight of the Profile beams placed thereon from their raised starting position into the lowered position and appropriately turned position.
- the swivel device only needs lifting equipment to lift the profile rack into the raised position Starting position.
- the lowering of the profile support tray back into the The turning position is then rotated by about 90 ° by the weight of the profile beams gravity-operated.
- the lifting means can basically be designed differently.
- a spring or other biasing device can be used to Bring profile support shelf to its raised starting position.
- the lifting devices work hydraulically.

- blocking means for blocking the pivotability of the profile support shelf.
- the blocking agents can be mechanical be trained.
- the blocking means are preferably hydraulic shut-off means preferably in the form of an electrically controllable switching valve for Shut off the hydraulic circuit, which is the hydraulic lifting device of the profile rack storage fed.
- the swivel device is free of energy from Excavator, crane or the like trained forth. It forms a self-sufficient system, with which can be raised and lowered the profile rack. hereby the turning device can also be operated independently of the excavator become. Only control connections have to be provided in order to ensure appropriate operation from the associated excavator. There are however, no hydraulic connections and no hydraulic supply from the excavator. The latter is also possible in principle.
- the self-sufficient described the design of the swivel device allows a larger area of application the turning device.
- the profile support shelf is expediently open on two sides, preferably approximately L-shaped. This is the top of the one placed on it Profile carrier or the profile carrier bundle in both positions of the profile carrier storage accessible so that the profile beams or the profile beam bundle from above, for example can be gripped with a magnetic gripper.
- the turning device is designed as a mobile carriage.
- the base frame can have a chassis, which is preferably a Movement in any direction allowed.
- the chassis can do this on all sides have rotatable wheels so that the turning device in any direction can be moved and positioned exactly in the desired position.
- On the base frame can be an attachment for attaching to an excavator, crane or the like be provided.
- the attachment device preferably comprises a um a horizontal axis rocker arm that can be used with the excavator or the like is boltable, so that the swing arm on opposite the excavator or the like can rock around a horizontal axis.
- the swing arm allows level differences balance in the floor area.
- the attachment is preferred formed such that the turning device is always in a predetermined position is held relative to the excavator, crane or the like. Even if the excavator moves, the turning device is moved accordingly. This is it advantageous if the chassis described above has wheels that can be rotated on all sides, that follow every movement of the excavator.
- the turning device 1 comprises one of several Steel profile girders, base frame 2 welded together like a truss several riot points on the ground.
- the base frame 2 a chassis 3, which comprises several freely rotatable wheels 4, so that the Base frame 2 is movable on the floor.
- An essentially L-shaped profile carrier shelf 5 is articulated on the base frame 2, namely, pivotable about a horizontal pivot axis 6.
- the profile support shelf 5 comprises two storage legs, which are arranged approximately at right angles to one another are. As can be seen in FIG. 3, they can be constructed from steel profile beams.
- the profile carrier shelf 5 is preferably in the area of one of its two shelf legs to the freely projecting end of the base frame 2 articulated as shown in Figures 1 and 2.
- a swivel device 7 are two hydraulic cylinders for the support 5 provided that pivotable on the one hand on the base frame 2 and on the other pivotably spaced from the swivel axis 6 on the profile support tray 5 are articulated.
- the pivoting device 7 can by the pivoting device 7 the profiled rack 5 between a raised starting position, the Figure 1 shows, and a lowered turning position, which Figure 2 shows, by about 90 ° be pivoted.
- In one position is the one leg of the profile rack 5 aligned approximately horizontally, while in the other position the other Leg of the profile support tray 5 comes to lie approximately horizontally.
- the profile support tray 5 is arranged and pivotable in such a way that they are in all swivel positions with their focus or with the focus the profile beams placed on it within the contact points of the base frame 2 lies.
- a hydraulic circuit 9 which at least one, in the embodiment shown comprises two pressure accumulators 10 which are connected to the hydraulic cylinders 8 via connecting lines.
- FIG 4 shows the pressure accumulators 10 on the one hand via a first line 11 to the Rod sides of the hydraulic cylinder 8 connected.
- the line 11 is throttle-free trained and only serves the feedback of stored on the rod side Hydraulic fluid.
- the pressure accumulators 10 have one second line 13 connected to the bottom sides of the hydraulic cylinders 8. In these second lines 13 are, on the one hand, electrically controllable switching valves 14 provided, by means of which the return line 13 can be blocked.
- FIG. 4 shows, there are 9 at the important nodes of the hydraulic circuit Pressure gauge 17 provided.
- a mounting device 18 is also fastened to the base frame 2 with the help which the base frame 2 are connected to the undercarriage 19 of the excavator can.
- the attachment device 18 comprises two in the embodiment shown Swing 20, which can be rocked about a common horizontal pivot axis the base frame 2 are articulated. With her facing away from the base frame 2 The wings 20 can also end about a common horizontal axis be pivoted to the undercarriage 19.
- the turning device works as follows:
- the profile rack 5 is by the swivel device 7 pressed into its upper starting position, in which the pivotally articulated Leg of the profile support tray 5 is aligned approximately horizontally.
- the hydraulic cylinders 8 are acted upon accordingly by the pressure accumulator 10, so that the profile rack 5 is pushed up.
- the profile beam bundle 21 to be turned is then placed on the profile beam tray 5 stored.
- the shut-off valves 14 are in their shut-off position, so that the profile support tray 5 is held securely in the starting position.
- the lifting grippers can then be released from the profile carrier.
- the switching valves 14 are opened, see above that the pressure fluid from the hydraulic cylinders flow back into the pressure accumulator can.
- the profile support tray 5 is therefore under the weight of the profile support bundle gravity-operated pivoted down to its turning position.
- the speed is controlled via the throttle 15.
