SUMI~fARY OF THE INVENTION
It is the primary object of this invention to provide a machine for continuously collecting and storing detached rail fastening elements with a high storage capacity for the elements so as to avoid frequent and time-consuming manipulation of storage containers.
The above and other objects are accomplished according to the invention with a machine which comprises a machine frame supported on undercarriages for mobility along the track and r e. ~ ~, cr ~
extending longitudinally in 'the direction of the track, a device for continuously collecting the rail fastening elements from the track, the device being vertically adjustably mounted on the machine frame, drive means for vertically adjusting the collecting device, an inclined conveyor arrangement mounted on the machine frame and extending in the direction of the longitudinal extension of the machine frame, the conveyor arrangement having a lower input end adjacent the collecting device and arranged to receive the collected rail. fastening elements therefrom, and a higher discharge end, and a container mounted on the machine frame below the higher discharge end and arranged to receive the discharged rail fastening elements, the container having two side walls extending in the direction of the longitudinal extension of the machine frame and a bottom constituted by a conveyor band extending in the direction of the longitudinal extension of the machine frame and being driven by an adjustable~speed drive.
6~lith such a machine it has become possible for the first time to store the detached rail fastening elements collected during a whole day of operations without any interruption due to the required manipulation of storage containers. It is particularly advantageous that no retrofitting work is needed for conveying the rail fastening elements discharged into the container at one end thereof to the opposite end so that the container may be completely filled. The discharge end of the conveyor arrangement remains stationary at the one container end, which simplifies the structure of the conveyor arrangement. This multiplies the storage capacity of the _3~
'~ ~;,3 machine and does away with the manipulation and transport of the small receptacles used heretofore.
According to a preferred feature of the present invention, the machine further comprises a damping device mounted between the discharge end of the conveyor arrangement and the bottom conveyor band for absorbing the impact of the discharged rail fastening elements on the bottom conveyor band. Such a structurally simple device will protect the bottom conveyor band from the damaging impact of the rail fastening elements while enabling the discharge end of the conveyor arrangement to be arranged higher above 'the bottom conveyor band to enable a higher filling level of the container to be achieved.
The damping device preferably comprises a damping plate connected to the container and having an elastic impact surface, the damping plate having two parts enclosing an angle with each other and extending symmetrically with respect to a vertical plane extending in the direction of the longitudinal extension of the machine frame, or a plurality of damping devices extending parallel to each other. This will provide not only effective damping but will also transversely distribute the discharged rail fastening elements in the container so that it will be filled uniformly across its width. This beneficial effect will be further enhanced with at least two damping devices, the damping devices extending in the direction of the longitudinal extension of the machine frame adjacent each other in a direction transverse to the longitudinal extension, and the adjacent damping devices being so spaced from each other and the container side walls, _4_ ~ i r ~~, n ~'l ;,1 ~ .~ r.~l respectively, as to define openings therebetween to permit free passage of the discharged rail fastenings therethrough.
The storage capacity of the container will be optimally utilized and a constant filling level will be assured if the machine further comprises a substantially vertical leveling element connected to the container adjacent the discharge end of the conveyor arrangement and extending transversely to the longitudinal extension of the machine frame, the leveling element having a lower edge spaced from the bottom conveyor band a distance corresponding to a desired level of the rail fastening elements stored in the container.
The container may be readily and completely emptied and the stored rail fastening elements may be removed to another car, for example, if the machine further comprises another inclined conveyor band mounted on the machine frame, the other inclined conveyor band having a lower input end below an output end of the bottom conveyor band at an end thereof opposite the discharge end of the conveyor arrangement.
A large capacity will be obtained with a machine frame comprised of two parts, the two parts being linked together, one of the machine frame parts supporting the collecting device, the conveyor arrangement and an operator's cab, and the other machine frame part supporting the container. The link between the two machine parts will enable such a long machine to travel in sharp curves. If the one machine frame part has a drive to constitute a self-propelled machine, and the other machine frame part constitutes a box car coupled thereto, the box car may be uncoupled when full and replaced ~., f~'J ~~ .... ;'r r p i_ , i .~.r i,t u.J 5,~ e~ ~t9 tr by an empty box car.
