Grinder truck
A grinder truck with a computer controlled profiler in combination with a vehicle automated guidance system for guiding a vehicle and equipment secured to a vehicle for removing of road markings. The computer controlled profiler detects the position of one or more grinding, grooving, rumbling heads in the X, Y and Z position. A controller and one or more actuators are manipulated in response to ground markings visible in a camera field. A remote controller allows an operator to control grinder heads individually, and allows for precise adjustment based upon an operator's visual inspection.
1. A multi-purpose grinder for use with a grinder truck comprising:
a grinder head having a plurality of carbide coated or diamond coated cutting teeth rotatably secured to the grinder truck;
a rotary encoder is attached to a wheel of the grinder truck in an x position to control the x position of said grinder head;
a vertical cylinder unit securing said grinder head to the grinder truck in a y position to control the up/down y position of said grinder head;
a horizontal cylinder unit securing said grinder head to the grinder truck in a z position to control the left/right z position of said grinder head;
a computer controller secured to each said cylinder, said computer controller electrically coupled to a plurality of encoders constructed and arranged to detect the position of said grinder head in the x, y and z position; and
a display screen electrically coupled to said computer controller for displaying and inputting adjustment to each said cylinder, said computer controller programmed with a plurality of pre-set moves, said pre-set moves allow a tap of said display screen to position move said grinder head, said display screen includes a cross-hair alignment screen to allow an operator to position a contrast sensor camera directly over a drip line or an expansion joint.
2. The multi-purpose grinder according to claim 1 wherein said rotary encoder determines said linear x position of the grinder truck by detecting wheel rotation.
3. The multi-purpose grinder according to claim 1 wherein said z position is detected by said contrast sensor camera.
4. The multi-purpose grinder according to claim 1 wherein said tap on said display screen moves said grinder head ⅛″.
5. The multi-purpose grinder according to claim 1 wherein said computer controller instructs said grinder head to move in predetermined patterns or profiles.
6. The multi-purpose grinder according to claim 5 wherein said pattern is further defined as a plunge cut to form a receptacle for a road marker.
7. The multi-purpose grinder according to claim 1 wherein each said cylinder is further defined as a slide cylinder with positional feedback.
8. The multi-purpose grinder according to claim 2 wherein said rotary encoder reassigns said grinder head to a master position.
9. The multi-purpose grinder according to claim 1 wherein said computer controller can incrementally move said grinder in either said x, y, or z position by use of a position input.
10. The multi-purpose grinder according to claim 9 wherein said computer controller detects a zero point, said zero point defined as the position where a cutting tooth touches pavement, said computer controller allowing adjustment of said zero point by position input.
11. The multi-purpose grinder according to claim 1 including a remote controller coupled to said computer controller, said remote controller provides computer controller input from a location separate from computer controller.
12. The multi-purpose grinder according to claim 1 including a screw actuator to provide a precise ending point and by operating said screw actuator at about 48 hertz to determine rotation for continually verifying said ending point.
