Abstract
A ridge in a lane of a roadway is ground away by providing a transverse beam carried on the support arms of a transport vehicle across a front of the vehicle, locating the vehicle longitudinally of the lane with the beam extending across the roadway and with the beam located by the vehicle in fixed position parallel to and above the ridge, moving a grinding assembly carried on the beam along the beam for grinding the ridge. The beam carries a gauge for a depth of grinding. The grinding assembly includes a toothed grinder rotatable about an axis transverse to the beam with a width transverse to the beam which is approximately equal to the width of the ridge.
Description
- This application claims the benefit of priority under 35 USC 119(e) of Provisional Application 61/445,368 filed Feb. 22 2011.
- This invention relates to a road grinding machine.
- Many roads particularly in cold environments develop transverse ridges in the asphalt which cross the pavement at spaced positions along the direction of travel. These cause severe undulations of travelling vehicles due to the periodic nature of the ridges and are a considerable source of discomfort for occupants. Up to now there has been no suitable dedicated machine for quickly and easily removing these ridges so that they need to be ground off by conventional machinery grinding the whole pavement or moved back and forth over the pavement.
- It is one object of the invention to provide a suitable dedicated machine for quickly and easily removing these ridges.
- According to one aspect of the invention there is provided an apparatus for grinding a ridge in a lane of a roadway comprising:
- a support assembly for attachment to support arms of a transport vehicle;
- a transverse beam carried on the support arms so that the transverse beam extends across a front of the vehicle whereby, with the vehicle standing longitudinally of the lane, the beam extends across the roadway;
- and a grinding assembly carried on the beam so as to be movable along the beam for grinding the ridge; whereby with the beam located by the vehicle in fixed position parallel to and above the ridge, the grinding assembly moves along the beam to grind the ridge.
- Preferably the beam carries ground engaging elements for locating a height of the beam above the ground whereby the gauge a depth of grinding.
- Preferably the grinding assembly includes a rotary member with an outer surface for engaging the ridge, the rotary member being rotatable about an axis transverse to the beam.
- Preferably the rotary member has a series of grinding teeth.
- Preferably the grinding member has width transverse to the beam which is approximately equal to the width of the ridge.
- One embodiment of the invention will now be described in conjunction with the accompanying drawings in which:
-
FIG. 1 is a schematic top plan view of an apparatus according to the present invention. -
FIG. 2 is a front elevational view of the apparatus ofFIG. 1 . - In the drawings like characters of reference indicate corresponding parts in the different figures.
- The apparatus for grinding a
ridge 16 in alane 18 of aroadway 17 includes asupport assembly 10 designed for attachment to supportarms transport vehicle 14. The vehicle can be of the type such as a skid steer loader or back hoe or other commercial tractor which includes front lift arms which can be operated using tractor controls. Thesupport 10 is designed to allow the apparatus to mount on the arms for movement by the arms, with the design be arranged to match the connections of the arms as is known to a person skilled in the art. Thelane 18 is defined byside lines 18A. - A
transverse beam 11 is carried on the support arms so that the transverse beam extends across a front of the vehicle whereby, with the vehicle standing longitudinally of the lane, the beam extends across the roadway to or slightly beyond theends 18A. - A
grinding assembly 20 is carried on the beam by a guide mounting 21 so as to be movable along thebeam 11 driven by adrive motor 22. Thus themounting 21 can form a sleeve mounted on suitable bearings which allows free movement along the beam between the ends of the beam by-passing thesupport 10. The grinding assembly is arranged for grinding theridge 16 with the beam located by the vehicle in fixed position parallel to and above the ridge. Thus thegrinding assembly 20 moves along the beam to grind the ridge back down to the level of theroadway 17. - The beam carries ground
engaging elements 27 engaging theroadway 17 for locating a height of the beam above the ground so as to gauge a depth of grinding down to theroadway 17 but no deeper. Thus the grinding assembly is at a constant height on the beam as it operates so that the height of the beam above theroadway 17 remains fixed with the vehicle stationary. - The grinding assembly includes a
rotary member 28 with anouter surface 30 of grindingteeth 29 for engaging the ridge, the rotary member being rotatable about an axis transverse to the beam. - The grinding member has a width W transverse to the beam which is approximately equal to the width of the ridge, typically of the order of 12 to 18 inches and much less than the length of the ridge or the width of the lane so as to grind only the ridge as the grinding assembly moves across the beam.
