DE8008474U1 - DEVICE FOR AVOIDING SPLASHES IN EMPTY PUMPS OF A CONCRETE PUMP - Google Patents

Description

2 0 4 4 2 Description

The present innovation relates to a device to avoid splashes when pumping out the intake or Dispensing container of a concrete pump.

This innovation is the preferred area of application for the so-called truck-mounted concrete pumps.

It can be assumed that the concrete pumps after the actual Must be emptied and cleaned in the concreting process. The first step in this regard usually involves emptying the reception or Dispensing container, which takes place in that the container contents are pressed into the conveying line. Because the action of the pump itself then stops when the container is empty, so when nothing can be pushed into the conveying line, generally falls in the Remaining concrete as a so-called residual amount of concrete. This is now pumped back into the container through a suction stroke.

There is a risk that concrete will splash over the edge of the container as a result of the compressed air

which ultimately leads to contamination of the pump environment and the concrete pump itself.

The task on which the present innovation is based is to Indicate means by which such contamination is to be avoided.

This object is achieved in that the recording or. Dispensing container a cover made of elastic material is provided.

The cover is advantageously on an upper edge of the

Recording or. Dispensing container screwed on. The innovation

is explained in more detail below with reference to the drawing. These

shows a complete truck-mounted concrete pump including the renovation;

adequate coverage. [

In the figure, a truck-mounted concrete pump is shown, the essential I

borrowed structural features a power car 1 with a body and §

Mounting frame 2 for building a pump and concrete f

ψ. divider unit are. The pump unit is designed as a piston pump

forms and schematically by a piston cylinder 3 and a |

Control unit 4 shown. This piston pump works according to the j _;

Principle of a tandem pump and presses each in a suction stroke f

Concrete column sucked out of a receiving or dispensing container 5 in a subsequent pressure stroke into a substantially
a V-shaped manifold (Y-pipe) 6 and a plurality
of conveyor pipes 7 existing concrete delivery line. About this <

Concrete delivery line, which is driven by a rotatable tower structure 8 "{

leads is and over height-adjustable arms 9 of a placing boom
is supported, the concrete is pumped to the desired location.
As a result of the tandem pump concept, one after the other
one or the other cylinder expressed a concrete column.

The innovation is that with the recording or. Submission |

container 5 is connected to a flat elastic cover 10,

in particular is screwed, the dimensions of which are chosen so X

that when cleaning the concrete pump, here the truck-mounted concrete pump,?

can be placed on the upper edge of the container 5. In order to
the container 5 is closed and the area around the concrete pump
as well as these themselves protected from concrete splashes.

With regard to the preferred field of application of the innovation according to the invention Cover, namely with truck-mounted concrete pumps, this cover then takes on an additional function when the truck-mounted concrete pump drives from one construction site to another with the container full. In these cases the cover prevents spilling over the contents of the container, for example when cornering.

In addition, it should be noted that the inventive,.

Cover is folded up during the actual pumping operation, whereby the concrete pump also during the filling process of the Receiving or dispensing container is protected from concrete splashes.
