" 2 Claims. (01. 248-23) This invention relates to portable supports for rotary and working platforms for oil field workover rigs.

An object of the invention is to provide an improved portable support for rotary and working platforms for oil field workover rigs which will afford a means for the easy and expeditious handling of the rotary and for making of adjustments which place the rotary directly over a well through the use of set screws and slots.

Another object of the invention is to provide an improved portable support forv rotary and working platforms for oil field workover rigs for either use with a rotary or when the rotary is not in use. The structure can be used as a platform for other operations, such as removing or putting in a casing or tubing, circulating the well, cementing, surveying or shooting.

A further object of the invention is to provide a steel constructed platform for supporting a workover rig rotary which will be highly eflicient in operation, and relatively inexpensive to manufacture and produce.

Other objects will appear as the description proceeds.

In the accompanying drawings which-form a part of this application,

Figure 2 is a partial sectional view taken on the line 22 of Figure 1;

Figure 3 is a partial sectional view taken on the line 3-3 of Figure 2;

Figure 4 is a perspective view of one end of one of the platform supporting beams with gusset plate attached thereto by welding;

Figure 5 is a perspective view of the angle iron supporting brackets secured to the end beams used for supporting the two beams running through the structure for rotary;

Figure 6 is a detail perspective view of a notched beam for supporting a rotary showing a truss plate or beam secured underneath the same for strengthening purposes;

Figure '7 is a detail perspective view of one of the corner supporting adjustable standards showing the base plate attached thereto; and

Figure 8 is a detail perspective view of one of the rotary supporting beams showing the adjusting beams for moving the rotary forward or backward to position it directly and squarely over the well.

Like characters of reference are used throughout the following specification and the accom- 2 panying drawings to designate corresponding parts.

In carrying out the invention, there is: devised and provided a highly efiicient steel beam portable support for rotary and working platform for oil field workover rigs which is intended to take the place of and do away with the old practice of forming a cribbing with large timbers.

In practice, four angle corner supporting standards are provided with large flat bases or feet 2 secured by welding 3 to their lower ends, and each side of the angle standards is formed with a plurality of adjusting openings arranged in spaced relation from top to bottom. These standards I are of whatever length desired to properly support the frame upon which the, rotary 5 and working platform of timbers (not shown) will be supported.

The supporting frame is formed by two I-beams 6 and I whose flanges are cut out at their opposite ends as at 8 to fit flush against the side flanges 9 of the angle corner supporting standards I, and the ends of the I-beams are provided with a series of openings I0 through which bolts I I will extend to hold the I-beams 6 and I to said corner supporting standards I in the desired adjusted height.

Similarly formed end I-beams I2 and I3 are also notched at their ends through their flanges I4 and are formed with a series of vertically spaced openings I5 for receiving the bolts I6 for securing the I-beams I2 and I3 to the corner supporting standards I.

Pairs of angle iron brackets I6 and I! are bolted in spaced relation to the end I-beams I2 and I3 for receiving the ends of the two rotary supporting I-beams I8 and I9 somewhat below the level of the end I-beams I2 and I3.

Spaced pairs of

angle brackets

20 and 2| are bolted to the central upper edges of the two rotary supporting I-beams I8 and I9 and are provided with adjusting bolts 22 for adjustably supporting the rotary 5 in position directly above the well.

The side I-beam 6 is notched out at 25 approximately centrally of its length to permit the rotary 5 to be supported below the level of the platform (not shown) to permit the frame to take the torque that is occasioned when tubing is placed in the well, and in drilling out cement and other contamination in the well.

Gusset plates 25 will be welded to the lower edges of the side I-beams 6 and I and the end I-beams I2 and I3 and will be provided with vertically spaced openings 26 for receiving bolts 21 for reinforcing and strengthening the frame support.

mantled portable and adjustable support for rotary and working platform for oil field workover rigs has been devised and provided.

While the preferred embodiment of the instant invention has been illustrated and described, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in details of construction may be resorted to without departure from the spirit of the invention.

Having described the claimed as new is:

1. A portable support for rotary and working platform for oil field workover rigs comprising angle corner standards having enlarged supporting bases on their lower ends, horizontally disposed end side and end I-beams having their flanges notched at their opposite ends for engaging the flanges of the standards, means for vertically adjusting said beams, spaced I-beams supported by and below the horizontal plane of said horizontally disposed and side I-beams for supporting a rotary drilling rig, means thereon for adjusting the'same forward or backward to overlie a well, and reinforcing gussets'welded to invention, What is the ends of said side and end I-beams having means for adjustably securing the same to said angle corner standards one of said side I-beams being notched intermediate the ends to provide a recessed seat to support a rotary drilling rig below the level of the platform when placed on said frame support.

2. A portable supporting stand comprising corner standards having enlarged supporting bases on their lower ends, horizontally disposed side and end I-beams having their flanges notched at their respective ends for adjustably engaging the standards, spaced supporting beams supported by and below the horizontal plane of the side and end beams, angle members mounted on said supporting beams for receiving a work piece or element, means adjustably' carried by the angle members for securing the work piece or element thereon and a recess formed in one of said side beams for accommodating one of the extending ends of the work piece or element.
