Description

Automatic feeding device for the filling frame by ramming hammers Ballast to be compacted from railway sleeper bearings The invention relates to a Device that has the purpose of the previous manual filling and tamping of the sleeper bearings to replace iron trough sleepers with better and more economical machine work.

So far, there are devices with rammers running on teaching rails for compacting railway sleeper bearings or for producing flat tamped surfaces became known, which, however, lacked the subject matter of the present invention.

In contrast to these known devices, the subject unites present invention, the previously separate operations of filling and tamping by the fact that the rammers provided, firstly, the inlet of the ballast from one Control and regulate ballast containers automatically and, secondly, the same in this way Compress the filling frame that the same progressively, according to the inflow of the Gravel, is tamped or compacted from bottom to top. In this way there is a fundamental difference to compression from bottom to top the previous production. of railway sleeper bearings.

The operation of the device is that a number of up and down moving rammers housed in a mobile machine frame and are evenly distributed over the entire working width. Spread the same the outlet of a container filled with gravel and cause by their up- and downward gear that the inlet of the ballast is automatically controlled, regulated and is compacted in the filling frame and after completion of the sleeper storage the other one Inflow remains complete.

The advantage of the arrangement over the known is that the previously unavoidable manual labor for filling and distributing the ballast in the Filling frames and their compression by hand rammers or machine-operated Replaced tamper by a thoroughly steady and progressive machine work and thus the track position is improved. Furthermore, the device makes essential economic advantages achieved and the construction times required up to now significant shortened. Also the construction and compression of the sleeper warehouse from the bottom down above merely offer a significant advantage over previous compression by pounding the top layer of the camp.

The drawing represents the subject matter of the invention schematically as follows: Fig. i: O_n section over an empty filling frame with lowered Ramming hammers in the initial position of the operation, Fig. 2: Position of the ramming hammers in their final working position, with the ballast container outlet simultaneously blocked by the downward-facing hammer surface, Fig.3: Completely filled and tamped filling frame viewed from the container side, the container and the guiding of the hammers are omitted.

After the usual filling frame b according to the threshold division are suspended on the master rails in a known manner, the mobile device placed on the latter, the ballast container d filled with ballast and the whole device moved over the filling frame b and the rammers g in their Subscript lowered to the bottom of the filler frame b. The rammers g are provided with a receding inclined surface o. As they move up and down the rammers g control and regulate the flow from the ballast container d Ballast automatically in such a way that the outlet st of the ballast container with each companionway d is released and a certain amount of ballast falls onto a guide rail na, with the ramming hammers g the feed into the filling frame up to the next high gear b is prevented by the inclined surface o. As soon as the ramming hammers are up again move upwards, the guide bar m becomes free, and the one on the guide bar The amount of ballast stored flows automatically into the filling frame b, while at the same time the outlet n through the downward directed under the inclined surface o Hammer surface is completed. In the following case of the hammers g, the one before crushed gravel that has run into the filling frame b and at the same time causes that the outlet ya is opened again and a new amount of gravel on the guide rail m falls, where it goes up to the next uphill passage through the receding sloping surface o is withheld. This process is repeated continuously, until the filling frame b is filled and compacted to form a rockfall rib, wherein the rammers g have reached their upper working position and thus automatically complete the run n.
