Patent Application
20230160185
The present invention relates generally to heavy construction equipment accessories and methodologies, more specifically but not by way of limitation, an apparatus configured to ensure the GPS location calibration of a construction equipment or a piece thereof is properly identified in order to ensure successful execution of grading or other type of industrial task.
GPS technology has expansive application, from helping farm tractors apply just the right amount of fertilizer to each area of a field, to helping ships and airplanes stay on course. As is known in the art, GPS technology is today also finding its way onto more and more earthmoving sites. In the past excavation sites were initially prepared with a multitude of stakes and lasers. However, the use of GPS on earthmoving sites and equipment has become more popular and the GPS integration onto heavy equipment falls into two categories of machine-control and grade-control. Machine-control systems, as the term implies, are designed to assist such machines as motor graders, dozers, scrapers, compactors and hydraulic excavators more efficiently cut and fill to grade. Efficiency is enhanced, because operators running machines equipped with GPS have essential information of where the machine is located on the site, and the position of its work tool in relation to the final grade.
A primary benefit of GPS machine-control is that earthmoving equipment can move through a site competently without grade stakes. Survey control points are still required but most stakes can be eliminated wherein some ninety percent of the stakes normally required on the same site without GPS are removed. This provides benefits such as lower survey costs especially on deep cuts and fills that would have required staking several times. The operator of a GPS-equipped machine, instead of searching for stakes and guessing about grade, sees a crisp, dean, full-color representation of the jobsite that gives exact grade information, anywhere on site on the controller in the operator's cab of the equipment. The operator can use this information to manually guide the machine to final grade, or, if the machine is equipped with an interface between the control system and the hydraulics, the blade is automatically positioned as the final grade approaches. However, it is important that the blade position is accurate and calibrated to ensure that the blade is in the proper location. While GUS technology is available, there is no apparatus or method to provide routine calibration of the blade of the equipment to ensure it is located in the proper location.
Accordingly, there is a need for an apparatus and method that is employed to provide routine calibration of the GPS location of construction equipment or an operational element thereof to ensure proper execution of the desired task.
It is the object of the present invention to provide an apparatus configured to provide routine location calibration of an element of construction equipment wherein the present invention includes a plate member having an upper surface.
Another object of the present invention is to provide a method and apparatus operable to ensure proper GPS location of construction equipment or an element thereof wherein the upper surface of the plate member includes alignment indicia thereon.
A further object of the present invention is to provide an apparatus configured to provide routine location calibration of an element of construction equipment wherein the plate member has coupled to the lower surface thereof a plurality of anchor members that are configured to penetrate into the ground.
Still another object of the present invention is to provide a method and apparatus operable to ensure proper GPS location of construction equipment or an element thereof wherein the plate member is penetrated into the ground such that plate member is adjacent the ground surface and the upper surface is in a level orientation.
An additional object of the present invention is to provide an apparatus configured to provide routine location calibration of an element of construction equipment wherein the present invention further includes a mounting post member for a GPS receiver.
Yet a further object of the present invention is to provide a method and apparatus operable to ensure proper GPS location of construction equipment or an element thereof wherein a step of the method of the present invention includes superposing an element of construction equipment on the alignment indicia.
Another object of the present invention is to provide an apparatus configured to provide routine location calibration of an element of construction equipment wherein a step of the method of the present invention includes pressing the plate assembly into the ground in a desired location.
Still an additional object of the present invention is to provide a method and apparatus operable to ensure proper GPS location of construction equipment or an element thereof wherein a step of the method of the present invention includes acquiring a GPS coordinate for the center of the plate member.
Yet another object of the present invention is to provide an apparatus configured to provide routine location calibration of an element of construction equipment wherein a step of the method of the present invention includes placing a GPS coordinate display adjacent to the plate assembly.
To the accomplishment of the above and related objects the present invention may be embodied in the form illustrated in the accompanying drawings. Attention is called to the fact that the drawings are illustrative only. Variations are contemplated as being a part of the present invention, limited only by the scope of the claims.
A more complete understanding of the present invention may be had by reference to the following Detailed Description and appended claims when taken in conjunction with the accompanying Drawings wherein:
Referring now to the drawings submitted herewith, wherein various elements depicted therein are not necessarily drawn to scale and wherein through the views and figures like elements are referenced with identical reference numerals, there is illustrated a construction equipment location calibration apparatus 100 constructed according to the principles of the present invention.
An embodiment of the present invention is discussed herein with reference to the figures submitted herewith. Those skilled in the art will understand that the detailed description herein with respect to these figures is for explanatory purposes and that it is contemplated within the scope of the present invention that alternative embodiments are plausible. By way of example but not by way of limitation, those having skill in the art in light of the present teachings of the present invention will recognize a plurality of alternate and suitable approaches dependent upon the needs of the particular application to implement the functionality of any given detail described herein, beyond that of the particular implementation choices in the embodiment described herein. Various modifications and embodiments are within the scope of the present invention.
It is to be further understood that the present invention is not limited to the particular methodology, materials, uses and applications described herein, as these may vary. Furthermore, it is also to be understood that the terminology used herein is used for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention. It must be noted that as used herein and in the claims, the singular forms “a”, “an” and “the” include the plural reference unless the context clearly dictates otherwise. Thus, for example, a reference to “an element” is a reference to one or more elements and includes equivalents thereof known to those skilled in the art. All conjunctions used are to be understood in the most inclusive sense possible. Thus, the word “or” should be understood as having the definition of a logical “or” rather than that of a logical “exclusive or” unless the context clearly necessitates otherwise. Structures described herein are to be understood also to refer to functional equivalents of such structures. Language that may be construed to express approximation should be so understood unless the context clearly dictates otherwise.
References to “one embodiment”, “an embodiment”, “exemplary embodiments”, and the like may indicate that the embodiment(s) of the invention so described may include a particular feature, structure or characteristic, but not every embodiment necessarily includes the particular feature, structure or characteristic.
Referring in particular to the Figures submitted as a part hereof, the construction equipment location calibration apparatus 100 includes a plate assembly 10.
