Sheet-metal molded part made from rubber or rubber substitutes for pipes on machines and devices, especially concrete pump

VEHICLE II *

The invention relates to a molded bearing part made of rubber or rubber substitutes for Storage of pipes on machines and devices, in particular concrete pump vehicles.

There are different types of pipe supports known which vibrations elastically absorb and destroy.

For machines and devices, especially concrete pump vehicles are provided for draining off in particular the concrete mass pipes, both during transport as well During the passage of concrete mixes at the work site are subject to strong vibrations, which result in mechanical oscillations and also in annoying noises impact i

The * 2 purpose "of the invention lies therein * at äölchett MaschineHj connected to the tube are a storage the RöhFe or the lines z "U create * with the not Hearing the yellow through the work movements of the machine generated vibrations * but also those during transport Mechanical vibrations occurring in such machines, on a motor vehicle! effectively prevented or at least can be steamed to the point of harmlessness, * and also while such a machine is working a workplace when passing liquid or pasty masses through the tube provide effective damping or * Destruction of the occurring mechanical vibrations and the sound vibrations is realized *

Accordingly, the invention is based on an elastically acting molded bearing part on bearings for pipes, in particular on concrete pump vehicles, and according to the invention, the bearing consists of an outer bearing ring to be held by a clamp and a radial flange with an opening for receiving a bearing ring arranged on the inner wall of the bearing ring on such concrete pump vehicles or similar machines to be fastened pipe. The design is preferably such that the molded bearing part is cut through radially at one point ₃ so that it can be easily placed around a pipe and then firmly but detachably connected to the actual bearing *

In a preferred embodiment of the invention, the ring flange extending radially from the bearing ring is provided with a widening or a _;

Support provided whose inner surface Hui ¹ immediate! Mounting a Röhreä ADRs * serves * ßäbei the execution is' getröffen FIOE that ööWöhl * bearing ring of Ringfiähsch and the inner bearing to the Ringfiänsch ice fiinstück rubber consist of as "äUöh barren a Kautschukersatzstöff * This design has the advantage that the entire molded bearing part can be manufactured as a cast or injection-molded part in a simple and inexpensive manner.

If required, it can be placed in the bearing ring an elastic metal stiffener in the form of a Wire or ribbon of existing stiffening insert be embedded, soft on the outer periphery of the bearing ring or something embedded in the bearing ring can be arranged.

There is still the possibility of an elastic stiffening insert in the ring flange and also in. to embed the inner support for the pipe.

Such a design has the advantage that in addition to the sound and vibration damping effect of the Rubber existing molded storage part, the suppression or destruction of vibrations is further promoted.

According to a further embodiment of the invention Depending on the type and frequency of the vibrations occurring, the molded bearing part can be made up of two Fabrics with different modulus of elasticity can be built up. This depends on whether the vibrations to be damped emanate more from the outside or from the pipe itself.

The execution can preferably be made in this way be that the annular flange and the support for the pipe are made of the same material and the annular flange into a circumferential inner groove of the bearing ring is embedded.

In the outer bearing ring 5 is a 9 Designated stiffener embedded or attached, which consists of a steel flat strip or of one or more Layers of steel wire can be made. Between the annular lugs 6 on the outer bearing ring 5 can with 10 and designated quick parts are inserted, so that the bearing molded part 4 with the aid of these clamp parts 10 and 11 can be attached at a desired location.

The molded bearing part is used to hold pipes or lines of different diameters are suitable, for example between 10 and about 150 mm.
