Problems solved by technology

While this can reliably measure any position of the swivel and thus also provides the system with the required redundancy, it requires high manufacturing complexity
Furthermore, these rotational angle sensors are rather bulky and have a rather high weight, which is disadvantageous for the lightweight construction of the entire machine
So the system is quite expensive overall

Embodiment Construction

[0024] figure 1 A so-called truck-mounted concrete pump is shown, and only those components of the truck-mounted concrete pump that are relevant for understanding the invention are shown. Vehicle-mounted concrete pumps of this type are generally known in the prior art and are characterized in that they are mounted on vehicles.

[0025] In the figures, the vehicle-mounted concrete pump is generally indicated by reference number 1, wherein the concrete pump mounted on the frame of the vehicle is indicated by reference number 2, and includes a steering wheel 3 also arranged on the frame, wherein the steering wheel It can rotate around its central axis 4 in various angular positions, and the vehicle-mounted concrete pump also includes a manipulator 5, which includes a plurality of manipulator arms. The concrete supply pipeline 6 is installed on the manipulator 5 .

[0026] From figure 2 It is obvious that the manipulator 5 is supported on the steering wheel at 6a by means of a...

Abstract

A device for conveying dense substances, in particular concrete, comprising: a pump for dense substances; a supply line leading from the pump; a manipulator receiving the supply line and comprising at least one mechanical arm and arranged on a steering wheel , the steering wheel is preferably provided with a swivel ring, the steering wheel can be rotated by a drive device, especially a hydraulic motor with a transmission mechanism, for the angular orientation of the manipulator, and the steering wheel can preferably be rotated by acting on the steering wheel The transmission gear on the ring rotates; and the measuring device includes a rotation angle sensor for measuring the rotation angle of the steering wheel by directly measuring the driving device or the transmission mechanism arranged between the motor and the steering wheel Rotate the angle to measure.

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 and a method according to the preamble of claim 11 . [0002] The present invention relates to concrete pumps, in particular truck-mounted concrete pumps, but it is not restricted to conveying concrete, but is also applicable in general to any type of dense substance, namely slurry. Background technique [0003] For above-ground building construction as well as for underground building construction, concrete pumps of various types and ratings are used to discharge the concrete, which is delivered on-site by mixing vehicles to form walls, roofs and the like. Thus, stationary concrete pumps as well as mobile concrete pumps, in particular so-called truck-mounted concrete pumps, are currently in use. In the case of truck-mounted concrete pumps, the pump is arranged on the frame or frame of the vehicle and sucks concrete from a filling hopper arranged at the vehicle, wherein the concret...
