This application hereby claims the benefit of German Application No. DE 10 2018 125 163.7, filed Oct. 11, 2018, which is herein incorporated by reference in its entirety.
The invention relates to a mobile thick matters pump for conveying thick matters, with a chassis, a pump unit arranged on the chassis, a charging hopper, open at the top, for charging thick matters which are to be conveyed, a pivotable cover, wherein the cover in a closure pivoted position closes the upper filling opening of the charging hopper and in an opening pivoted position uncovers the filling opening of the charging hopper, and with a rear light assembly.
Thick matters pumps known from the prior art have rear light assemblies coupled rigidly to the chassis, which comprise for example a rear light oriented permanently in a particular position in relation to the chassis. What is problematic about the rigid rear-light holders known from the prior art is that they mostly project out from the contour of the chassis. In construction-site operation, such holders are susceptible to damage due to collisions.
Pivotable, hinged or adjustable devices are also known from the prior art for protecting the rear light assemblies better from collisions in construction-site operation, while the rear light assemblies in road operation are positioned as wide or as far to the outside as possible. Such a device is known for example from DE 20 2016 007 988 U1. What is disadvantageous about the solution described here is that the rear light assembly in construction-site operation is arranged beneath the charging hopper and hence in a region which readily becomes soiled when charging thick matters which are to be conveyed. Furthermore, the rear light assembly in construction-site operation continues to be located in a region in which damage can easily be caused when backing truck mixers up to the charging hopper. Thus the rear light assembly when charging thick matters which are to be conveyed, in particular concrete, is easily damaged or fouled, and further is in the way, which may furthermore lead to collisions.
The object of the invention is therefore to devise an improved thick matters pump which makes a simple and safe arrangement of the rear light assembly possible in construction-site operation. In particular, damage to and fouling of the rear light assembly when charging thick matters which are to be conveyed into the charging hopper by way of the upper filling opening thereof is to be avoided.
This object is achieved by a thick matters pump having the features of the claims.
Due to the fact that the rear light assembly is arranged on the pivotable cover and is designed to be pivotable together with the cover, a safe arrangement of the rear light assembly when charging into the charging hopper thick matters which are to be conveyed can be made possible in a simple manner. To this end, the rear light assembly on the pivotable cover is pivoted together therewith. Thus the rear light assembly on the construction site during pumping operation of the thick matters pump is not in the way during the charging into the charging hopper of thick matters which are to be conveyed. In the opening pivoted position of the cover, the rear light assembly is pivoted along with it, so that it is not soiled by thick matters when charging into the charging hopper. By way of the pivoting of the rear light assembly together with the pivotable cover, a safe position for the rear light assembly can be set particularly simply.
The rear light assembly is preferably formed by two red reflectors. Furthermore, the rear light assembly preferably comprises two direction indicators, which further are preferably designed as yellow flashing signal lights. In addition, the rear light assembly may comprise two red tail lights which indicate the end of the vehicle. Moreover, the rear light assembly may have two brake lights which indicate braking of the vehicle. Moreover, the rear light assembly may comprise reversing lights, rear fog lamps and a number-plate light.
Advantageous configurations and developments of the invention will become apparent from the dependent claims. It should be pointed out that the features listed individually in the claims may also be combined with one another in any technologically sensible manner whatsoever and thus reveal further configurations of the invention.
According to one advantageous configuration of the invention, provision is made for the rear light assembly in the closure pivoted position of the cover to be oriented counter to the direction of travel of the chassis. With the orientation of the rear light assembly in the closure pivoted position counter to the direction of travel of the chassis, the end of the chassis can be perceived safely by road users following behind even at dusk, during the hours of darkness or in poor weather conditions. The orientation of the rear light assembly is set by the main direction of beam of the lights forming the rear light assembly, which lights in the closure pivoted position of the cover shine mainly counter to the direction of travel of the chassis.
Particularly preferred is an embodiment which provides for the cover to be pivotably articulated in the region of its edge which is on the direction-of-travel side, so that it is pivoted upwards in the direction of travel out of the closure pivoted position, in which the cover is oriented substantially horizontally, into the opening pivoted position, in which the cover is oriented substantially vertically. With the opening of the pivotable cover, the rear light assembly can be brought simply into a position to the front above the charging hopper, where the rear light assembly is safe from soiling and damage during the charging into the charging hopper of thick matters which are to be conveyed.
One particularly advantageous embodiment of the invention relates to the rear light assembly being fastened to the cover by way of a subframe. With the fastening of the rear light assembly by way of the subframe, the arrangement of the rear light assembly can take place independently of the shape of the cover. Thus legal stipulations for the arrangement of the rear light assembly can be met simply and independently of the configuration of the cover and the charging hopper.
One particularly advantageous embodiment of the invention provides for the subframe to project beyond the width of the cover transversely to the direction of travel of the chassis, and for the rear light assembly to be arranged, offset at least partially in the direction of travel of the chassis, on the subframe laterally next to the cover. In the case of particularly wide vehicles, such as truck-mounted concrete pumps, it may be necessary to arrange the rear light assembly, partially in the direction of travel of the chassis, on the frame laterally next to the cover in order to comply with the legal maximum distance of for example the flashing signal light and tail light from the outside of the vehicle. In this manner, parts of the rear light assembly can be arranged very simply independently of the shape of the cover and of the charging hopper in the direction of travel laterally next to the latter.
One advantageous embodiment of the invention provides for a working light to be arranged on the cover, which light in the opening pivoted position of the cover illuminates the charging hopper from above. With such a working light, in the opening pivoted position of the cover the charging hopper, the upper filling opening thereof and the region around the charging hopper can be illuminated sufficiently so that it is possible to work safely even at dusk or in darkness.
