Abstract
A drilling rod retainer which effects safe handling of a drilling rod substantially independently of any auxilliary power equipment. The rod retainer is designed for placement on a drilling rig and support frame, and has two retaining arcuate arms which are biased, through use of at least one high tension spring connected between each of the arms, to substantially surround the drilling rod, when the retainer is in a normally closed position. The retaining arms have integrally connected flange portions that extend downwardly below the arms in order to provide additional surface area to hold and secure the drill rods as they are being removed from the down hole well.
Description
DRILLING ROD RETAINER
This invention relates generally to a drilling rod retainer and, more particularly, to a drilling rod retainer which effects safe handling of drilling rod sections of a drill string substantially independently of any auxilliary power equipment.
BACKGROUND OF THE INVENTION
Underground drilling, such as gas, oil, or geothermal drilling, generally involves drilling a bore through a formation deep in the earth. Such bores can be formed by connecting a drill bit to long sections of pipe, which can be referred to as a "drill rod sections," so as to form an assembly commonly referred to as a "drill string." The drill string extends from the surface to the bottom of the well bore. These sectioned drill rod sections can be successively added to the drill string during a drilling operation (to increase the length of the drill string), and successively removed in the drill raising operation, normally by means of a drill raising machine.
These drill rod sections, in which it is not uncommon for each of these sections to be, for example, between 5 and 20 feet long, can be very heavy. According to prior art practices, each of these drill rod sections, whether they be added to or removed from the drill string, has to be hoisted into and out of the drill raising machine, and be further positioned by a hoist for threading thereof to the drill string (or unthreaded therefrom, depending upon the operation).
Due to the large size and weight of the drill rod sections, dangers can be presented to workmen around the drilling operation in the form of the drill rod sections accidentally falling into the working environment of the workmen during removal, replacement or insertion of the drill rod sections.
Further dangers to the workmen can present themselves in the form of drill rod sections becoming swung, or otherwise unstable, during harsh environmental conditions, such as high winds.
Thus, there is a need for an improved drilling rod retainer which can provide for safe handling and replacement of drilling rod sections of a drill string. There is a further need for an improved drilling rod retainer which can operate substantially independently of any auxilliary power equipment. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
The object of the present invention is to provide an improved drilling rod retainer which can provide for safe handling and replacement of drilling rod sections of a drill string during drilling operations.
Another object of the present invention is to provide an improved drilling rod retainer which can operate substantially independently of any auxilliary power equipment.
A still further object of the present invention is to provide an improved drilling rod retainer having two retaining arcuate arms which are biased, through use of a high tension spring connected between each of the arms, to substantially surround the drilling rod, when the retainer is in its normally closed position, the retaining arms having integrally connected flange portions that extend downwardly below the arms in order to provide additional surface area to hold and secure the drilling rod sections during removal, replacement or insertion from the down hole well.
According to one aspect of the present invention, there is provided a drilling rod retainer for attachment to a drilling rig support frame and constructed and arranged for securing and retaining a drill rod comprising a base portion constructed and arranged for attachment to the drilling rig support frame; first and second arcuate retaining arms pivotally connected to the base portion and positioned on opposed sides of the base portion so as to spaced apart from one another, the retaining arms defining an opening between them for receiving and allowing the drill rod to pass and extend vertically therethrough, the retaining arms being constructed and arranged to assume both an open position for receiving the drill rod and a normally substantially closed position for substantially surrounding and securing the drill rod therebetween; at least one high tension spring adapted for attachment to each of the first and second arcuate retaining arms, the at least one high tension spring biasing the first and second arcuate retaining arms between the open position for receiving the drill rod and the normally substantially closed position; and a pair of downwardly extending flange portions integrally connected to respective ones of the retaining arms for providing additional surface area to secure and surround the drill rod therebetween.
According to another aspect of the present invention, there is provided a drilling rod retainer for use with and attachment to a drilling rig support frame and constructed and arranged for securing and retaining a drill rod comprising a base portion constructed and arranged for attachment to the drilling rig support frame; first and second arcuate retaining arms pivotally connected to the base portion and positioned on opposed sides of the base portion so as to spaced apart from one another, the retaining arms defining an opening between them for receiving and allowing the drill rod to pass and extend vertically therethrough, the retaining arms being constructed and arranged to assume both an open position for receiving the drill rod and a normally substantially closed position for substantially surrounding and securing the drill rod therebetween, and wherein the retaining arms flare outwardly, from substantially a mid-point of each of the arms to end portions thereof, lip portions integrally connected to to respective ones of the retaining arms, which extend upwardly from an upper surface of the arms at approximately a mid-point of each arm and extending along the arms to a position substantially near an outermost end of the arms; a high tension spring adapted for attachment to each of the first and second arcuate retaining arms, the at least one high tension spring biasing the first and second arcuate retaining arms between the open position for receiving the drill rod and the normally substantially closed position; and a pair of downwardly extending flange portions integrally connected to respective ones of the retaining arms for providing additional surface area to secure and surround the drill rod therebetween, wherein the when the drill rod is to be positioned between the retaining arms, the drill rod is aligned to sliding contact the lip portions of the retaining arms, and, as the drill rod is pushed between the retaining arms, the drill rod slides along the lip portions and the retaining arms resiliently spread apart to the open position to receive the drill rod, whereby, when the drill rod is secured therebetween, the at least one high tension spring biases the retaining arms to the normally substantially closed position.
As previously discussed, the advantage of the present invention is that it provides an improved drilling rod retainer which can provide for safe handling and replacement of drilling rod sections of a drill string during drilling operations.
A further advantage of the present invention is that it provides an improved drilling rod retainer which can operate substantially independently of any auxilliary power equipment.
A still further advantage of the present invention is that it provides an improved drilling rod retainer having two retaining arcuate arms which are biased, through use of a high tension spring connected between each of the arms, to substantially surround the drilling rod, when the retainer is in its normally closed position, the retaining arms having integrally connected flange portions that extend downwardly below the arms in order to provide additional surface area for stabilizing and securing the drilling rod sections during removal, replacement or insertion thereof from the down hole well.
These and other objects and embodiments of the inventive disclosures made herein will become readily apparent upon further review of the following specification and associated drawings.

BRIEF DESCRIPTION OF THE DRAWINGS
A preferred embodiment of the present invention is described below with reference to the accompanying drawings, in which:
FIGURE 1 is a side perspective view of one embodiment of the drilling rod retainer of the present invention;
FIGURE 2 is a top view of the embodiment of the drilling rod retainer shown in Figure 1;
FIGURE 3 is a bottom perspective view of the embodiment of the drilling rod retainer shown in Figure 1, shown in operation on a drilling rig support frame; and FIGURE 4 is a bottom perspective view of the embodiment of the drilling rod retainer shown in Figure 1, shown in operation on a drilling rig support frame.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Figures 1 to 4 depict an embodiment of the drilling rod retainer of the present invention.
With reference to Figures 1 and 2, the drilling rod retainer 1 of the present invention, which is preferably made of metal, is designed for placement and mounting on a drilling rig support frame, and includes a base plate or portion 13 having a first arcuate arm 3 and a second arcuate arm 5 attached thereto. Preferably, these arms 3,5 are secured to a top portion of the base plate 13 by means of bolts (not shown) or the like. As can also be seen in Figure 1, a bottom portion of the base plate 13 extends generally at a right angle from the top portion of the base plate, whereby the bottom portion of the base plate 13 is in a generally vertical orientation. In this manner, the top portion of the base plate 13 is in substantially perpendicular relationship to the bottom portion. As will hereinafter be described, it is the base plate 13 of the drilling rod retainer of the present invention that is secured, by means of mounting holes 14 (shown in Figure 2), to the drilling rig support frame 27 shown in Figure 3.
With reference to Figures 1-4, it can be seen that each of the arms 3,5 has an arcuate body shape, which flares outwardly from substantially a mid point of the arms 3,5 to end portions thereof (19 and 21 respectively), so as to resemble a "boomerang" type of construction, which is of an importance which will hereinafter be described. The arms 3, 5 are in a normally closed position, and, when in such position, define a hole or bore between them to allow for a drill rod section 25 of a drill string (as seen in Figures 3 and 4) to pass and extend vertically therethrough. It should be noted that the dimensions of the hole or bore are such that standard drill rod sections can slide through the hole between the arms 3,5 , while still providing a surface area to securely retain the drill rod section therebetween, as would be apparent to one skilled in the art. Preferably, the hole or bore defined between the retaining arms is substantially circular in shape.
In a preferred embodiment, the arms 3,5 are biased in the normally closed position through at least one high tension spring 7 which is interconnected between and to mounting brackets 15, 17 which are mounted upon the arms 3,5. In this manner, when the drill rod section 25 is in place between arms 3,5 , the high tension spring 7 biases the arms 3,5 to substantially surround the drill rod section 25, it being understood that the amount of tension which could be utilized to bias the arms 3,5 to substantially surround the drill rod section 25, could be varied, as would be apparent to persons skilled in the art. It will, of course, be understood that more than one high tension spring 7 can be utilized, as would be readily apparent to one skilled in the art.
As can be seen with reference to Figure 3 and 4, the first retaining arm 3 and the second retaining arm 5 have integrally connected flange portions 9, 11 that extend downwardly below the arms, in an outwardly extending orientation. In this manner, flange portions 9, 11 provide additional surface area to hold and secure the drill rod sections 25 during removal, replacement or insertion thereof from the down hole well. As noted previously, flange portions 9, 11 of the arms 3,5 prevent or substantially inhibit a drill rod section 25 from swinging or becoming unstable during removal, replacement or insertion thereof, or during harsh environmental conditions, such as high winds. In a preferred embodiment, these flange portions 9, 11 are integrally connected to the arms 3,5.
With reference to Figures 1 and 2, each of the arms 3, 5 have corresponding integrally connected lip portions 23, 24, respectively, which extend upwardly from an upper surface of the arms, the lip portions 23, 24 being positioned on the arms 3,5 to begin at approximately a mid-point thereof of each arm, and extend along the arms to a position substantially near an end of the outermost end of the arms 3,5. In this manner, the lip portions 23, 24 provide a greater surface area, at an encirclement point 26 in Figure 2 (where the arms 3,5 substantially encircle and surround the drill rod section 25 secured therebetween), for the drill rod retainer of the present invention to safely maintain the drill rod section 25 in place.
In operation In use, the drilling rod retainer of the present invention is secured, by means of mounting holes 14 (shown in Figure 2) to the drilling rig support frame 27 shown in Figure 3, it being understood that other configurations of such attachment are conceivable.
Preferably, once positioned, a lower end of the base plate 13 will assume a substantially parallel orientation with the drilling rig support frame 27.
In positioning the drilling rod retainer to substantially surround and retain the drilling rod section 25 shown in Figures 3 and 4, the drilling rod section 25 can be positioned so as to contact lip sections 23, 24 on the arms 3,5. As noted previously, end portions 19 and 21 of the arms 3,5, respectively, form the arms 3,5 to resemble a "boomerang" type of construction, which construction is of an importance in aligning the drilling rod section 25 into position into the hole or bore defined between the arms 3,5. As the drilling rod section 25, during the insertion thereof, is, pushed towards encirclement point 26 shown in Figure 2, the drilling rod section 25 contacts and engages lip sections 23, 24 along end portions 19 and 21, and, as the drilling rod section 25 continues to be pushed, the shape of end portions 19 and 21 of the arms 3,5, draws the drilling rod section 25 towards the encirclement point 26 shown in Figure 2, at which point the arms 3,5, biasingly open to permit entry of the drill rod section 25 into the hole or bore defined between the arms 3,5. Once the drilling rod section 25 is in place, the arms 3,5, by virtue of their connection to the high tension spring 7, biasingly close, thus retaining the drilling rod section 25 therebetween. In this manner, the drilling rod retainer of the present invention is utilized to hold drill rod sections 25 during removal, replacement or insertion thereof from a down hole well. Alternatively, it would also be conceivable to have a workman, or machinery, biasingly pry the arms 3,5 to an open position to allow for disconnection the drilling rod retainer of the present invention from engagement with the drill rod section 25.
As noted previously, the first retaining arm 3 and the second retaining arm 5 have integrally connected flange portions 9, 11 that extend downwardly below the arms, in an outwardly extending orientation, so as to provide additional surface area for the drilling rod retainer of the present invention to hold and secure the drill rod sections 25 in place.
The present invention has been described herein with regard to preferred embodiments.
However, it will be obvious to persons skilled in the art that a number of variations and modifications can be made without departing from the scope of the invention as described herein.
There are numerous variations and modifications thereof that will also remain readily apparent to others skilled in the art, now that the general principles of the present invention have been disclosed.
FIGURE 2 is a top view of the embodiment of the drilling rod retainer shown in Figure 1;
FIGURE 3 is a bottom perspective view of the embodiment of the drilling rod retainer shown in Figure 1, shown in operation on a drilling rig support frame; and FIGURE 4 is a bottom perspective view of the embodiment of the drilling rod retainer shown in Figure 1, shown in operation on a drilling rig support frame.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Figures 1 to 4 depict an embodiment of the drilling rod retainer of the present invention.
With reference to Figures 1 and 2, the drilling rod retainer 1 of the present invention, which is preferably made of metal, is designed for placement and mounting on a drilling rig support frame, and includes a base plate or portion 13 having a first arcuate arm 3 and a second arcuate arm 5 attached thereto. Preferably, these arms 3,5 are secured to a top portion of the base plate 13 by means of bolts (not shown) or the like. As can also be seen in Figure 1, a bottom portion of the base plate 13 extends generally at a right angle from the top portion of the base plate, whereby the bottom portion of the base plate 13 is in a generally vertical orientation. In this manner, the top portion of the base plate 13 is in substantially perpendicular relationship to the bottom portion. As will hereinafter be described, it is the base plate 13 of the drilling rod retainer of the present invention that is secured, by means of mounting holes 14 (shown in Figure 2), to the drilling rig support frame 27 shown in Figure 3.
With reference to Figures 1-4, it can be seen that each of the arms 3,5 has an arcuate body shape, which flares outwardly from substantially a mid point of the arms 3,5 to end portions thereof (19 and 21 respectively), so as to resemble a "boomerang" type of construction, which is of an importance which will hereinafter be described. The arms 3, 5 are in a normally closed position, and, when in such position, define a hole or bore between them to allow for a drill rod section 25 of a drill string (as seen in Figures 3 and 4) to pass and extend vertically therethrough. It should be noted that the dimensions of the hole or bore are such that standard drill rod sections can slide through the hole between the arms 3,5 , while still providing a surface area to securely retain the drill rod section therebetween, as would be apparent to one skilled in the art. Preferably, the hole or bore defined between the retaining arms is substantially circular in shape.
In a preferred embodiment, the arms 3,5 are biased in the normally closed position through at least one high tension spring 7 which is interconnected between and to mounting brackets 15, 17 which are mounted upon the arms 3,5. In this manner, when the drill rod section 25 is in place between arms 3,5 , the high tension spring 7 biases the arms 3,5 to substantially surround the drill rod section 25, it being understood that the amount of tension which could be utilized to bias the arms 3,5 to substantially surround the drill rod section 25, could be varied, as would be apparent to persons skilled in the art. It will, of course, be understood that more than one high tension spring 7 can be utilized, as would be readily apparent to one skilled in the art.
As can be seen with reference to Figure 3 and 4, the first retaining arm 3 and the second retaining arm 5 have integrally connected flange portions 9, 11 that extend downwardly below the arms, in an outwardly extending orientation. In this manner, flange portions 9, 11 provide additional surface area to hold and secure the drill rod sections 25 during removal, replacement or insertion thereof from the down hole well. As noted previously, flange portions 9, 11 of the arms 3,5 prevent or substantially inhibit a drill rod section 25 from swinging or becoming unstable during removal, replacement or insertion thereof, or during harsh environmental conditions, such as high winds. In a preferred embodiment, these flange portions 9, 11 are integrally connected to the arms 3,5.
With reference to Figures 1 and 2, each of the arms 3, 5 have corresponding integrally connected lip portions 23, 24, respectively, which extend upwardly from an upper surface of the arms, the lip portions 23, 24 being positioned on the arms 3,5 to begin at approximately a mid-point thereof of each arm, and extend along the arms to a position substantially near an end of the outermost end of the arms 3,5. In this manner, the lip portions 23, 24 provide a greater surface area, at an encirclement point 26 in Figure 2 (where the arms 3,5 substantially encircle and surround the drill rod section 25 secured therebetween), for the drill rod retainer of the present invention to safely maintain the drill rod section 25 in place.
In operation In use, the drilling rod retainer of the present invention is secured, by means of mounting holes 14 (shown in Figure 2) to the drilling rig support frame 27 shown in Figure 3, it being understood that other configurations of such attachment are conceivable.
Preferably, once positioned, a lower end of the base plate 13 will assume a substantially parallel orientation with the drilling rig support frame 27.
In positioning the drilling rod retainer to substantially surround and retain the drilling rod section 25 shown in Figures 3 and 4, the drilling rod section 25 can be positioned so as to contact lip sections 23, 24 on the arms 3,5. As noted previously, end portions 19 and 21 of the arms 3,5, respectively, form the arms 3,5 to resemble a "boomerang" type of construction, which construction is of an importance in aligning the drilling rod section 25 into position into the hole or bore defined between the arms 3,5. As the drilling rod section 25, during the insertion thereof, is, pushed towards encirclement point 26 shown in Figure 2, the drilling rod section 25 contacts and engages lip sections 23, 24 along end portions 19 and 21, and, as the drilling rod section 25 continues to be pushed, the shape of end portions 19 and 21 of the arms 3,5, draws the drilling rod section 25 towards the encirclement point 26 shown in Figure 2, at which point the arms 3,5, biasingly open to permit entry of the drill rod section 25 into the hole or bore defined between the arms 3,5. Once the drilling rod section 25 is in place, the arms 3,5, by virtue of their connection to the high tension spring 7, biasingly close, thus retaining the drilling rod section 25 therebetween. In this manner, the drilling rod retainer of the present invention is utilized to hold drill rod sections 25 during removal, replacement or insertion thereof from a down hole well. Alternatively, it would also be conceivable to have a workman, or machinery, biasingly pry the arms 3,5 to an open position to allow for disconnection the drilling rod retainer of the present invention from engagement with the drill rod section 25.
As noted previously, the first retaining arm 3 and the second retaining arm 5 have integrally connected flange portions 9, 11 that extend downwardly below the arms, in an outwardly extending orientation, so as to provide additional surface area for the drilling rod retainer of the present invention to hold and secure the drill rod sections 25 in place.
The present invention has been described herein with regard to preferred embodiments.
However, it will be obvious to persons skilled in the art that a number of variations and modifications can be made without departing from the scope of the invention as described herein.
There are numerous variations and modifications thereof that will also remain readily apparent to others skilled in the art, now that the general principles of the present invention have been disclosed.
