Abstract
An improved mechanism for grinding surfaces flat is presented, involving a precision grinder with grinding heads that are adjustable in a vertical dimension controlled by a support structure on wheels. The support structure has an adjustable wheelbase that allows sinusoidal flaws in a surface to be ground down in a controllable way. The device can be used in coordination with floor flatness measurement devices to grind concrete floors, and other horizontal surfaces.
Description
- This application claims the benefit of Provisional Application 61/032,411, filed Feb. 28, 2008, entitled “Truss Grinder System”.
- The present invention relates to the field of floor levelness and floor flatness ensurance. More particularly, the invention relates to surface grinding and planing devices to increase surface flatness.
- The present invention provides a distinct advance in the state of the art by grinding a concrete floor, rail, plinth, sleeper, and the like to exact tolerances as described by the data output of profiling devices that may or may not be with the prior art.
- This invention employs a wheeled truss and this truss is used not only as the main guide which the invention uses to stabilize its precision grinding heads, but also to house the components that control the unit. These components consist of a variety of electric, hydraulic, manual, electromechanical, hydro, and internal combustion devices all of which can be configured together to unite a self-sustained unit for the purpose of correcting elevation tolerances on specific concrete surfaces.
- In an alternate embodiment, the present invention can also be fitted with accelerometers and inclinometers to produce surface profiles of what the device ‘sees’ as it travels down a path and it can produce a profile indicative of the finished ground surface.
- The present invention solves the prior art problems discussed above and provides a distinct advance in the state of the art. This device can rest upon a concrete rail or surface and grind the high crests down thereby shallowing the troughs of the surfaces sinusoidal chords as represented by
-
y(t)=A·sin(w t+q) - which describes a wavelike function of time (t) with:
- 1) peak deviation from center=A (amplitude),
- 2) angular frequency w,
- 3) phase q.
- This wave pattern occurs often in nature, including ocean waves, sound waves, light waves and wet concrete when in the liquid stage before hardening. Concrete finishing devices cause a rhythmic patter and unwanted waves are the result. Also, a rough sinusoidal pattern can be seen when emulating the path of a vehicle such as a car, bus, or truck, and other vehicles. When these wave patterns occur in concrete, they must often be repaired and that is the job of this invention.

FIG. 1 is a side view of the truss planer -
FIG. 2 is a top view of the truss planer -
FIG. 3 is a rear view of the truss planer - A preferred embodiment of the surface truss planer apparatus of the present invention, referred to as a truss planer, is displayed in
FIG. 1 through 3 . The truss planer is comprised of articulatingwheels 101 supporting atruss frame 103 on which rests aplenum plate 104. Thecutting motor 109 is suspended from thetruss frame 103 and the shaft of the drive motor is connected to thecutting heads 102. The shaft of thecutting motor 109 passes through theplenum plate 104, which possesses bearings for thecutting motor 109 shaft. Theplenum plate 104 also provides up and down positioning of thecutting heads 102 using thecontrol arms 105. - The
adjustment wheel 106 is mounted on a fixed bearing that when turned, adjusts a precision-threaded shaft that pushes or pulls thecontrol arms 105, raising or lowering theplenum plate 104. Thecontrol unit 107 is where the components that run the truss planer's systems reside. It specifically controls the process of rotating the cutting discs and using the drive train. Thedrive train 108 is connected to one of the articulating wheels and propels the truss planer under the control of thecontrol unit 107. There is awater tank 110 on board the truss planer to cool the cutting blades - The articulating
wheels 101 at the four corners of thetruss frame 103 act as an averaging filter of the bumps on the surface on which they ride; the surface can be any surface including rails. If rails or similar reference form are used, the articulatingwheels 101 can be adjusted a pre-determined amount to affect the reshaping of the surface being planed. - The
cutting heads 102 can be adjusted and positioned anywhere from left to right, or fore and aft by means of thecontrol arms 105 and theadjustment wheel 106. With thetruss frame 103, the distance between front and rear axles can be varied by changing the truss length by means of theadjustment wheel 106 operating on the attached precision-threaded shaft to plane a surface, referencing the contour waves of the surface to change the surface profile. Thecutting head 102 can be positioned anywhere to create a change in the resulting surface profile. - Although the invention has been described and a preferred embodiment has been provided, equivalent features may be employed and substitutions made within this specification without departing from the scope of the invention as recited in the claims.
