Sweeping device for working on a track system
View Patent ↗A sweeping device works on a track formed of rails and sleepers. The sweeping device has a brush shaft formed from a plurality of shaft portions configured as hollow shafts, and resilient sweeping elements protruding radially from the brush shaft. The sweeping device can be attached via at least one adjustable vertical drive to a vehicle that can travel on rails. It is provided that at least one axis of rotation of a shaft portion is adjustable via a control shaft with control elements acting externally on the shaft portion.
1. A sweeping device for working on a track formed of rails and sleepers, the sweeping device comprising:
a brush shaft having a plurality of shaft portions each configured as a hollow shaft;
resilient sweeping elements protruding radially from said brush shaft;
at least one adjustable vertical drive for attaching the sweeping device to a vehicle that can travel on the rails;
a frame supporting said brush shaft, said at least one adjustable vertical drive is connected to said frame;
a control shaft having control elements, at least one shaft portion of said shaft portions being adjustable about one axis of rotation via said control shaft by said control elements acting externally on said shaft portion.
2. The sweeping device according to claim 1 , wherein said control elements are joined to said control shaft being a rotatably mounted control shaft and are configured in a sword-shape.
3. The sweeping device according to claim 1 , further comprising:
a mechanical linkage; and
at least one gear, said control shaft is rotated via said mechanical linkage and said at least one gear.
4. The sweeping device according to claim 3 , wherein said at least one gear is a worm gear.
5. The sweeping device according to claim 1 , further comprising cardan joints, individual ones of said shaft portions of said brush shaft are movably connected via said cardan joints.
6. The sweeping device according to claim 1 , further comprising at least one laterally disposed chain drive, said brush shaft is driven by means of said at least one laterally disposed chain drive.
7. The sweeping device according to claim 1 , wherein said brush shaft has five said shaft portions.
8. The sweeping device according to claim 1 , wherein two of said control elements act on a central part of said shaft portions, with one of said control elements each acting on a bearing point on a left and a right of the central part.
9. The sweeping device according to claim 1 , further comprising a common brush box, said brush shaft and said control shaft with their associated drive and bearing components are disposed in said common brush box.
10. The sweeping device according to claim 1 , wherein said resilient sweeping elements, which are resilient and radially disposed on said brush shaft, are made of solid material or internally hollow, tubular products.
