P 23 54-574.6 and P 24-19 797-5 of the applicant. These Patent applications describe the use of an automatic tightening device in conjunction with an elongated guide which is rigidly attached to a mold for concrete slabs or the like. here enables that which can be achieved with the fixed clamping device rapid release of the vibrator rapid displacement of the same along the guide without the vibrator needs to be dismantled for this purpose.

The devices and methods described in the cited patent applications are extremely advantageous and economical and have already found practical use. Nevertheless, there is always the possibility of further modifications and improvements, such as, for example, the present invention creates. These relate to a novel arrangement for attaching the vibrator as well as a different version of pressure fluid operated clamping devices. In this context, it can be assumed that that in the area of application of vibrators mostly with flowable, granular and abrasive material is being worked on. Together with the very large forces and pressures that occur, it causes or promotes it such material has an excessive wear and tear and thus requires a light and economical Interchangeability of individual parts, especially parts made of elastic materials in the clamping devices. In the examples given, this relates to the elastic hollow bodies, which are used in Wear or damage must be completely replaced.

According to the invention, a holder of the type mentioned is characterized by a rigid support part with a first surface facing the wearer and a second surface facing away from the wearer through on the second surface arranged formations for the rigid

Attachment of a force-exerting device by at least a clamping device rigidly connected to the supporting part with a cylinder having a substantially closed end on the first surface and a has an open end facing the wearer, and an im Cylinder arranged piston, which one at the open End of the cylinder facing the carrier and one opposite, with the closed end of the Cylinder has an end face delimiting a chamber that can be charged with a pressure medium and can be relieved of pressure, and by means for supplying and releasing a pressure medium into and from the chamber, the piston being essentially made of an elastic, flexible one Material and in the case of pressure supply and pressure relief of the Chamber in the axial direction towards the guide or from it is deformable away and its end face facing the carrier is a along the circumference with this one-piece edge part and a central part protruding in the axial direction towards the carrier above it, which comes on earlier when the chamber is pressurized the carrier comes into contact as the edge part.

The hollow bodies mentioned in the cited patent applications are therefore replaced by a piston-cylinder arrangement according to the invention. The cylinder is a simple, annular part which is welded or otherwise rigidly attached to the supporting part, and contains a simple piston made of elastically deformable material. In the event of wear or damage of the piston only needs this and not the whole Arrangement to be replaced. The leadership or the The side of the piston facing the device to be vibrated is convex towards the guide, so that the middle part is at Pressure feed of the cylinder first comes into contact with the guide and only afterwards the other parts of the relevant end face of the piston. Thanks to this training and its flexibility, the piston returns

Depressurization of the cylinder to its original. Shape back.

In an advantageous embodiment of the invention, FIG the center of the surface of the piston facing the guide a piece of material used, which has a greater hardness has as the main part of the piston, thus extending the service life of the piston. That in question The piece of material is preferably one that is embedded in the center of the piston and protrudes slightly towards the guide Steel ball. This also reduces the friction between the piston and the guide, so that the support slide with the vibrator effortlessly along the guide can be moved »from the convex design of the piston surface and that of a web or rim surrounded, cup-shaped configuration of the On the inside of the piston, there is an increased contact pressure and thus an improved seal between -.:. : u see the piston rim and the cylinder wall. the axial outward movement of the piston is not limited by the cylinder, allowing inadvertent pressurization of the cylinder does not cause excessive expansion after the support carriage has been removed from the guide or deformation of the piston, but only causes the piston to fall out.

Another important feature of the invention is that the vibrator or some other working device though rigid, but detachable on: mounting slide can be attached is, so that if the support carriage or the fixed clamping devices are damaged, the vibrator will not or the working device to be replaced needs. In an advantageous embodiment of the invention, the support slide has several cylinder-piston arrangements with a common pressure connection for simultaneous actuation. To produce the: common Pressure connection is the part that carries the vibrator as

one with all cylinders flow-connected and Devices for supplying and discharging one Pressure means exhibiting BpticSikaiaier formed. That The part in question is preferably made of steel sheets welded to one another in a pressure-tight manner and has with it a solid and at the same time economical layout.

The following are exemplary embodiments of the invention Describe on the basis of the drawing. Barin show:

In the drawing, maxi recognizes a Fakroag 10 "whose purpose is anfeaiid waaifebeispielen · vorsteüend"^; was explained. In the presented! Aiasflihnsaig is

the guide is a C-profile with a web 12 and each other opposing, inwardly angled belts 14. As stated at the beginning, the guide.-10 can pretty much be long, so that simple and fast-acting clamping devices are required to a Eüttler to be able to move quickly into numerous different positions.

The support carriage 16 is described below, with the inwardly angled belts 14 of the guide cooperating parts held on this and carries a rigid, but removable Eüttler attached to it 18. This can be of any type, for example of the type mentioned in detail in the introduction Patent applications described. It is therefore, for example, one supplied by a source 20 Compressed air operated Eüttler (Fig. 6, 7).

The support carriage 16 has a base plate 22 made of steel with a length and width necessary to accommodate a suitable number of clamping devices described in detail below. The base plate ¹ has lateral protruding, with the inwardly angled. Straps 14 of the guide 10 can be brought into engagement with edges 24 and carries a pair of rollers 26 which facilitate the displacement of the support carriage from one position to the other along the guide. Handles 27 attached to opposite ends of the base plate 22 also serve to move the carriage and to lift and carry it. The drawing shows the guide 10 in an upright position, but it can also be arranged differently. The arrangement shown corresponds to the intended use mentioned in the second cited patent application in connection with a casting mold for concrete slabs. The design and operation of the edges 24 of the base plate 22 and the straps

6 0 9 8 3 3/0526

the driving 10 can also be reversed, i.e. the leadership could be a simple I-profile and the edges 24-could be angled inwards towards each other.

On the underside or inside of the base plate 22, i.e. on the side facing the belt 12 of the guide is a number that are equal to one another. Clamping devices 28 arranged. Brackets 26a for the rollers 26 are each provided with a weld 26b between the outer pairs of clamping devices attached, (Fig. 5).

Each clamping device 28 has a cylinder 30 », preferably in the form of a ring or ring web Steel which is welded pressure-tight to the underside of the base plate 22. In the example shown four clamping devices each contain one essentially made of a flexible, elastic material molded piston 32 such as rubber. Has in the relaxed, pressure-relieved state the end face of the piston protruding at the open end of the cylinder in the direction of the guide 10 convex shape, i.e. the middle part protrudes further than the surrounding edge parts.

The central part of the piston has an inwardly protruding thickening 34- into which a hardened Insert part 36 is inserted. This preferably has the shape of a steel ball or is another part made of a material that is harder and more wear-resistant as about rubber and compared to the belt 12 has a lower friction than this. The piston 32 has essentially Cup shape, with a moving in the direction of the closed end of the cylinder 30, so on -the Base plate 22 to be tapered edge web 38. The dem Belt 12 of the guide .10 facing bottom of the piston can extend from the thickened middle part 3 ^ to the edge web

5G9833 / 0S26

also taper towards what its deformability between the two end states shown in Fig. 3 and 4 · relieved.

Thanks to the convex design of the piston head, its middle part carrying the insert or the ball 36 comes first in contact with the guide, whereupon the edge parts surrounding the middle part are placed against them until Finally, the entire piston crown is in contact with the Belt 12 is located (Fig. 4). This deformation of the piston also increases the pressure system of the Ring web 38 on the inner wall of the cylinder 30. The The resulting improved sealing contributes to the avoidance of pressure medium losses and prevents this Penetration of foreign bodies into the clamping device.

Due to the use of several clamping devices 28, the support carriage 16 has on its the the Clamping devices 28 supporting side opposite side a support spar 40, preferably in shape of an overhead U-profile made of steel, which is welded pressure-tight to the base plate 22 and closed at both ends 42 so that it a manifold pressure chamber 44 forms. This is via a corresponding number of passages 46 with the individual fixed clamping devices 28 flow-connected and has an outwardly leading threaded bore 48 for the connection of a pressure line.

The support bar 40 serves not only as a pressure chamber but also for the detachable attachment of the vibrator 18, for example by means of a pivot 50 and a retaining screw 52 or the like .. The type of attachment is only here shown as an example and can also be implemented in other ways. In operation, the vibrator 18 is rigid with connected to the support carriage 16.

509833/0526

In the example shown, compressed air is used as the pressure medium, but a hydraulic fluid or the like can also be used instead. Fig. 6 shows a schematic representation of the pressure medium supply with. the pressure source 20, the pressure chamber 40, the vibrator 18 and a hard-saving device 28 and with two pressure lines .54, 56 i ⁿ each of which a valve 58 and 60 is used. Such an arrangement is used to actuate the clamping devices 28 and the vibrator 18 independently of one another via the two valves 60 and 58, respectively.

In Fig. 7 a pressure medium feed for automatic operation is shown. In this mode of operation the clamping devices 28 become essentially at the same time as the vibrator 18 is started up actuated. One recognizes here a pressure line 62 with a valve 64 inserted therein, which leads to the pressure chamber 40 leads, and a line 66 leading from the pressure chamber 40 to the vibrator 18. When the valve is opened 64 the pressure medium flows through the inlet 48 into the pressure chamber 40, where it is the clamping devices 28 feeds and thus causes it to attract, and from there to the vibrator 18 to set it in motion. On the When the valve 64 closes, both the vibrator 18 and the clamping devices 28 are depressurized. In the two embodiments shown in FIGS. 6 and 7, the pressure feed causes the clamping devices 28 the tightening of the same, whereupon the vibrator in the position thus determined over a required period of time is put into operation. After pressure relief of the clamping devices can move the support slide together with the vibrator into another position without having to do this by the Guide 10 would have to be removed.

509833/0526

When the support slide is moved, it is removed from the inserts or balls located in the middle of the pistons 36 and supported by the rollers 26. In the pressurized state, the individual pistons have a Sufficiently large contact area with the guide 10. In the event of wear, damage or the like replace the pistons individually, effortlessly and economically. In the event of damage, the support carriage 16 can be replaced as a whole without also renewing the vibrator 18. The. Cylinders 30 are economical and can be produced without difficulty from pipe sections, and the overall structure as a welded construction enables significant savings in manufacturing costs.
