Definitions
- the invention relates to a spreading device as described in the preamble of claim 1.
- Rescue equipment for salvaging, in particular people from vehicles etc., after accidents in which the vehicles, in particular the bodies, have deformations and people are trapped and / or doors for salvage cannot be opened or cannot be opened sufficiently e.g. known by the applicant under the designation SPS 330.
- These rescue devices consist of a unit of a hydraulic drive, a cylinder and valve unit and a pair of swivel arms operated with it, which can be used on the one hand to expand when the swivel arm pair expands and on the other hand as scissors for cutting metal parts when the swivel arm pair closes.
- a disadvantage of a rescue device known from the prior art is the opening width of the arms limited by the Kinematic, which in turn depends on the handling-related restrictions with regard to the dimensions and the total weight of the rescue device.
- the object of the invention is to create a device which, with the usual size and weight of such rescue devices, comprises a spreading area through the opening widths as specified in the regulations for the formation of "man openings", e.g. known from the regulations on pressure vessels, corresponds, is achieved.
- the surprising advantage here is that by arranging a pressure tappet arrangement which can be actuated by the swivel arms, the spreading area of the recovery device is doubled without the use of larger drives and with only an insignificant increase in the weight of the device.
- an embodiment according to claim 2 with the pressure tappets adjustable via a guide arrangement is also advantageous, since an exact alignment of the spreading forces to be applied to the generally irregularly extending edge regions of wall and structural components is achieved and the optimal spreading effect is independent of the force components of the reaction forces that occur comes into effect in the longitudinal central axis predetermined by the longitudinal central axis of the pressure ram arrangement.
- a design as described in claim 3 is also advantageous because high resistance moments of the guide arrangement are thereby achieved which counteract a buckling of the pressure ram arrangement.
- An embodiment as described in claim 6 is also advantageous, according to which an exact movement dependence of the telescopic profile arrangement is achieved.
- Claims 7 and 8 also describe a preferred further development, whereby subsequent and also optional equipping of a standard recovery device with a pressure ram arrangement to enlarge the spreading area is possible.
- a preferred development describes claim 11, whereby torsional forces that may occur, such as can occur when spreading irregularly shaped wall parts, materials, etc., are absorbed.
- Formations according to claims 14 to 16 are also possible, which makes it possible to fix the pressure tappet arrangement in the spreading position after completion of an expansion process and thus to effectively prevent springing back of the spread parts in the non-driven state or when the spreading device is uncoupled.
- a sufficient distance from the areas hindering the rescue of a person is in a the order of magnitude corresponding to the standards or safety requirements.
- an embodiment according to claim 18 is also advantageous because it achieves non-slip support of the expansion device on sheets, plastics, which generally have very smooth surfaces.
- FIG. 1 shows a spreading device according to the invention with a recovery device in view.
- FIG. 2 shows the spreading device in a view offset by 90 ° compared to FIG. 1;
- FIG. 5 shows a further embodiment of the chaff according to the invention? Device in view.

- a control unit 10 for example a button-operated multi-way valve 11, is arranged on the cylinder 5 for alternately acting on a piston 12 of the cylinder 5 or for blocking the supply line 6 and return line 7.
- the cylinder 5 has a housing 15 on a front end region 14 penetrated by a piston rod 13, in which a common bearing arrangement 18 is provided for a pair of pivot arms 16, 17, in which the bearing arrangement is mounted and in a direction perpendicular to a pivot axis 19 of the bearing arrangement 18 extending pivot plane 20 are pivotable in the manner of scissors.
- the drive takes place via the piston rod 13 of the cylinder 5, which is in drive connection with the swivel arms 16, 17 via a lever arrangement 21.
- the finger-like swivel arms 16, 17 are designed, for example, for a cutting process during the closing movement and with claws for a spreading process during the opening movement, a standard having emerged according to which a maximum spreading width 22 is between 300 mm and 350 mm, preferably 330 mm.
- driver elements 25, 26 are arranged on projecting end regions 23, 24.
- the further description regarding the driver elements 25, 26 as well as their design and connection with the swivel arms 16, 17 is subsequently created for the swivel arm 16 with the driver element 25 and applies analogously to the further swivel arm 17 and the driver element 26.
- the driver element 25 comprises the swivel arm 16 in a U-shaped manner, a base web 28 forming a stop 29 abutting against a back surface 30 and legs 31, 32 overlapping regions of the swivel arm 16 on side surfaces 33, 34.
- the legs 31, 32 and the swivel arm 16 are provided with bores 35 which run perpendicular to the side surfaces 33, 34 and which are penetrated by a plug pin 36 for connecting the driver element 25 to the swivel arm 16, whereby a releasable connection is achieved.
- a den A den.
- the pivot arm 16 projecting end portion 37 of the driver element 25 is provided with fork-like actuating claws 38, 39, which have radial bearings 40, which are in particular formed by divided pivot axes 41, which are arranged concentrically to one another in the actuating claws 38, 39 and form a pivot axis 41, which in runs approximately perpendicular to the pivot plane 20.
- the driver 25 is supported further by engaging behind a connecting web 43 of the actuating claws 38, 39 through an end region 23 of the swivel arm 16 designed as an expanding claw 44, via which the spreading forces are transmitted to the driving element 25.
- the connecting web 43 with the actuating claws 38, 39 form a fork head 45, this design being identical to the design on the further swivel arm 17 with the driver element 26.
- Pressure tappets 46, 47 of a pressure tappet arrangement 48 are supported in the radial bearings 40 of the driver elements 25, 26 via bearing pins 49, 50.
- the pressure rams 46, 47 are e.g. formed from pipe sections 51, which are guided concentrically and axially stable with respect to a longitudinal central axis 53 running in the pivot plane 20 via a guide arrangement 52 and are adjustable relative to one another via the pivot arms 16, 17 and their driver elements 25, 26 in the direction of the longitudinal central axis 53 .
- the guide arrangement 52 is designed as a telescopic profile arrangement 54, which is formed from tube sections 55, 56, 57 which can be moved into one another.
- the pressure tappet arrangement 48 consists of the tube sections 51 forming the pressure tappets 46, 47.
- Each of the tube sections 51 has a length 58 running approximately in the direction of the longitudinal central axis 53, which corresponds approximately to half the minimum spreading width 22.
- the pipe sections 51 are provided with end caps 60 closing them, e.g. welded to these, which are provided with approximately pyramid-shaped extensions 61, which project above end faces 62.
- These extensions 61 enable a non-skid approach for wall parts 63 to be spread, e.g. body parts, etc.
- mutually facing end faces 64, 65 of the pipe sections 51 lie on top of one another and also the
- the profile arrangement 54 formed from the pipe sections 55, 56, 57, which forms the guide arrangement 52 for the pressure rams 46, 47.
- the profile arrangement 54 is provided with grooves 67 and pins 68 of a stop arrangement 69 with regard to the displacement path of the individual Pipe sections 51, 55, 56, 57 coupled to one another in order to achieve a coordinated movement of the pipe sections 51, 55, 56, 57 when extending and retracting the pressure ram arrangement 48.
- the driver elements 25, 26 are also moved by the expanding claws 44 or by contact surfaces 73 formed thereon, against which the connecting webs 43 of the fork heads 45 are supported, and thus the pressure tappet arrangement 48 in Direction of the maximum spread 70 moves.
