3 Claims.
This invention relates to the construction of floors of derricks which are used in the rotary method of drilling oil wells and more particularly to a floor construction which is such that the rotary may be adjustably positioned over the mouth of the well ibore.
In the drilling of oil wells by the rotary method, a rotary is supported above the mouth of the well and is utilized to drive the drill string to which a suitable bit is attached at its lower end.
It has been a practice to secure the rotary in position upon the derrick floor so that the axis of the table will be in alinement with the mouth of the well bore.
For most efficient results it is desirable to have the axis of the rotary table coincide with the axis of the bore hole at its mouth. Misalignment may occur due to slight shifting of the rotary. The present invention is designed to overcome this difiiculty and maintain the rotary in desired position relative to the bore hole.
It is a general object of the invention to provide an adjustable rotary support which is so constructed as to facilitate positioning of the rotary over the mouth of the bore hole.
It is also an object to provide a rotary support for conveniently positioning the rotary preliminary to drilling and also for thereafter repositioning the rotary if desired or necessary.
It is a further object to provide a rotary support including support members and retaining side members, the latter of which are provided with means for readily and accurately positioning the rotary upon the support members.
Other and further objects will be apparent from the following description taken in connection with the drawing in which:
Fig. l is a plan view partly in section showing a construction embodying the invention.
Fig. 2 is an elevational view of the construction shown in Fig. 1.
Fig. 3 is a detail showing a modified construction for retaining the cross members in position relative to the side members.
In each of Figs. 1 and 2 there are shown sills l and 2 at the sides of the derrick floor supporting transverse members 3 and 4 in spaced relation on opposite sides of the bore hole. Intermediate the sills and 2 there are spaced support members 1 upon which the platform generally indicated as lll is supported. The rotary (not shown) is secured to this platform with the rotary table overlying the opening in the platform.
It is to be noted that the platform in is posiof the platform Hi.
tioned between the side members 3 and 4 and that the side members are provided with jack screws i2 having end plates l3 which engage the sides of the platform. By means of the jack screws 12 the platform I i! may be accurately and readily positioned transversely of the side members 3 and 4 so that the center or axis of the rotary table indicated as l5 may be made to coincide with a line parallel to the side members.
At each end of the platform ii) the side members 3 and 4 are provided with slots IE to receive tongues ll extending outwardly from the ends of the cross members It and I9. These cross members are adapted to engage the ends Jack screws 2i! are threadably connected to blocks 2| fixed to the side members 3 and 4. By adjustment of these jack screws the platform It and the rotary mounted thereon may be positioned longitudinally of the side members and may also be held securely between the cross members l3 and i9.
An alternative of the tongue and slot construction shown in Figs. 1 and 2 is illustrated in Fig. 3 wherein the cross member I9 is shown as terminating adjacent the side member 3 and is maintained movably relative thereto by means of angle irons 22 and 23 which are secured to the side member 3 as by weld metal 25.. As is apparent this alternative construction avoids the necessity of providing openings in the side members as shown at [6 in Figs. 1 and 2. Likewise it is unnecessary in this modification to provide tongues H on the ends of the cross members I8 and I9. Other than these specific fea tures the construction is the same as shown and construction just described the platform I!) may be positioned accurately either transversely or longitudinally of the side members 3 and 4 so that the axis l5 of the rotary table may be brought to any desired position whereby the principal and secondary objects of the invention are attained.
Broadly the invention comprehend-s a construction whereby the rotary table of a well drilling rig may be readily brought into desired position relative to the bore hole which is drilled thereby.
What is claimed is:
1. A mounting for adjustab-ly positioning a well drilling rotary over the mouth of a well bore comprising two longitudinal side members, spaced cross members between said side members to form therewith a rectangular opening, slots in the side members at the ends of the cross members, tongues on the ends of the cross members projecting into said slots to support and guide the cross members longitudinally of the side members, means for supporting the rotary within said opening, means for adjusting the position of the rotary transversely oi the side members, and means for moving the cross members longitudinally of the side members to adjustably secure the rotary in position with respect to the side members.
2. A mounting for adjustably positioning a well drilling rotary over the mouth of a well bore comprising two longitudinal side members, spaced cross members between said side members to form therewith a rectangular opening to receive a rotary, means on the side members for guiding the cross members longitudinally of the side members, means for supporting a rotarywithin said opening, means attached to the side members for adjustably positioning the cross members longitudinally of the side members, and additional means attached to the side members for adjustably positioning the rotary transversely thereof.
3. A mounting for adjustably positioning a well drilling rotary over the mouth of a well bore comprising two longitudinal side members, spaced cross members between said side members to form therewith a frame having a rectangular opening to receive the well drilling r01- tary cooperating means on the cross members and side members for guiding the cross members longitudinally of the opening, means beneath said frame and extending transversely of the side members for supporting a rotary within the opening in the frame, and means on the side members for adjustably securing the rotary in position upon the support means.
