Problems solved by technology

[0012] In the state of the art, various devices are known for the controlled mixing of the components into a defined mixture, but no device is known that enables the bonding of ballast beds in one process over hundreds of meters along railway tracks. With this controlled and precise adhesive application, the unit is quick and flexible to use

Embodiment Construction

[0034] figure 1 One application is shown, namely longitudinally cut ballasted tracks just outside rail sections, which were previously bonded by spraying two-component epoxy resin so that they form quasi-monomeric blocks. In this state, the ballasted road can be removed by excavating the shovel, as shown here, but it remains stable so that the vertical walls can be cleared without the ballasted track significantly losing its load-bearing strength and stability. Ballast. Whenever e.g. cables or pipes have to be laid along such a rail section, there are serious problems with maintaining the stability of the rail track if trains run continuously on it (i.e. during installation work on the pipeline or pipe) . Where routine stabilization is not possible, track sections will have to be closed for rail traffic, which will mean severe restrictions and costly downtime for rail operators.

[0035] figure 2 Another ballasted track is shown, which is stabilized by gluing and then cut...

Abstract

The device for discharging multi-component adhesives consisting of at least two fluid components (A, B) onto a granular ballast bed (6) of a railway rail section (4) consists of at least two separatecarriages, preferably three carriages (1, 2, 3). The carriages can be loaded into a vehicle or a trailer (48) by only two people in that the interior of the vehicle or the trailer is equipped with rails (50, 51) on which the carriages (1, 2, 3) can be rolled. Thus, the carriages can be transported on roadways so as to be brought to the location of use quickly and be put into operation, wherein thecarriages are placed on the tracks (4) of the railway from the trailer (48) via retractable rails (51). The device allows adhesives to be applied onto a ballast bed (6) over long distances in a fullyautomated manner such that all specifications are met and the ballast bed is adhered such that normal train traffic can continue. The entire device can be loaded, transported, unloaded on-site, and put into operation by only two people.

Description

technical field [0001] The invention relates to a device for discharging a multi-component adhesive having at least two fluid components onto a mixture of granular bodies, in particular for discharging a multi-component adhesive onto ballast of a railway track superior. In this process, two fluid components are controllably delivered from a storage tank at precisely controllable flow rates using a gear pump through a mixer unit via two separate feed lines, thereby forming a sprayable fluid adhesive mixture. A spray unit with a spray bar (with a plurality of discharge nozzles) is used for the purposeful discharge of the binder mixture onto the ballast bed. In addition, the invention relates to a method of applying this device and its use for the discharge of multi-component adhesives onto ballast of railway track tracks. Background technique [0002] Today, railways are an important part of long-distance and local mass transport infrastructure. Rail superstructures cannot...
