H. N, HERRICK APPARATUS FOR HANDLING DRILL PIPE DURING ROTARY DRILLING Filed Aug. 15, 1954 Patented July 28, 1 936 UEE STATES APPARATUS FOR HANDLING; DRILL PIPE- DURING ROTARY DRILLING? Henry N. Herrick, Berkeley; Calif., assignor to Standard (Bil Company of Galifornia,
6 Claims;
. This invention relates to an apparatus for handling pipe during rotary drilling and more particularly to an apparatus for automatically moving. drill.- pipe laterally of a derrick when such pipe has been. raised clear of the hole being drilled.
In the drilling of oil wells it has been the general. practice to. withdraw the drill pipe from the hole. the distance of a single stand of the drill pipe to apoint where the lower end of the stand of. drill pipe is clear of the hole being drilled, after: which time the stand of drill pipe withdrawn is disconnected and moved laterally of the derrick by manual labor.. These stands of pipes. are racked within the derrick and to one side thereof. Usually the distance to which the lower end. of the pipe must be moved: manually is about 10. feet. Each of these stands is generally about 85 feet long and weigh about a ton. This handling of the drill pipe is very severe manual labor. The severeness of this labor is most always aggravated by the fact that the floor of the derrick is covered with slippery mud which renders the operation dangerous and has resulted in many injuries and some deaths. Also very few men' have sufficient endurance to rack 6,000 feetof pipe continuously, which causes the operation of witi'idrawing the pipe from the hole. to be. frequently interrupted.
It is one object of this invention to provide a mechanicald'evi'ce for overcoming the above difficulties.
Another objectis to provide a mechanical device that will automatically operate to move a stand of drill pipe laterally of the derrick when the lower end of such pipe has been raised free and clear of the hole being drilled.
Another object is to provide a mechanical device that will operate efficiently to obviate the heavy manual labor during the racking of drill pipe whereby the manual labor required to rack pipe being drawn from a hole is limited to guiding the pipe to the pipe rack.
A further object is to provide a mechanical device having the above characteristics that will be so constructed and positioned as not to interfere with the other operating parts of the derrick.
A still further object is to provide a. device having the above characteristics that shall be simple in structure, durable, positive and efficient in operation and that can be produced at a very small cost.
The accomplishments of the above and other objects of the invention will be apparent to those skilled in the art-whentaken in connection with the accompanying drawing wherein like reference characters refer to like parts. It is to be expressly understood that. the drawing is not a definition of the invention but merely illustrates certain forms by meansof which the invention may be effectuated- In the drawing:
Figure 1. is an elevational view more or less diagrammatic of a derrick illustrating one embodiment of the invention.
Figure 2 is a view similar to Figure 1, showing a drill pipewithdrawn from the hole and the present invention. in readiness to move the pipe laterally of the derrick.
Figure3 isa view similar to Figures 1 and'Z illustrating. theposition. of the pipe after being moved. laterally of. the derrick.
Figure l. is a sectional view taken along the line IV- -IV of- Figure 3.; and
Figure 5 is a view similar to Figure 4., illustrating adifferent. position in which the present invention may be placed. on the derrick.
With reference to'Figures 1 to 4, inclusive, one formof' the invention is disclosed in connection with. a. conventional derrick represented in its entirety by Hi. The derrick comprises the usual foundation H, floor I2. and legs 43, the latter usually being. four in number. .The derrick is providedwith the usual safety platform. M, crows nest i5, crown block l6, traveling. block. H. and drilling, cable l8;
As illustrated in Figures 1 to 4, inclusive, the
drill pipe 1'9" is connected to the traveling block H by means of a swivel 2i and hook 22. The traveling block ill is raised by the drilling cable It, carrying with it the pipe 19 to the position shown by Figure 2, at which time the lower end of the drill pipe is disconnected from the upper end of the cooperating stand of drill pipe. After the cooperating ends of the stand of the drill pipe have been disconnected, the stand l9 withdrawn from the hole is in readiness to be moved to the pipe rack. The pipe rack is positioned to one side of the derrick and the cooperating derrick floor is generally cushioned, as shown at 23, in order to prevent the scarring or impairing of thelower end of the pipe 89, which rests thereon. The derrick is also provided with a horizontal member 24, usually referred to as a finger, positioned intermediate the height of the derrick and adjacent a swinging frame represented in its entirety by 25. The frame 25 is turnably mounted to a horizontal member 26, fixed to the derrick legs at about mid-way the height of the derrick. The frame 25, which may consist of a free end 21 and a pair of legs 28 for connecting the free end 2! with the horizontal member 26, the opposite ends of the legs 28 from the free end 21' being turnably mounted to the horizontal member 26 at 29 by any suitable means.
The swinging frame 25 is operably connected to the traveling block I! by any suitable means such as a chain or flexible cable 3|. Two cables are preferably provided, one for connecting each of the legs 28 to the traveling block I1. The cables 3| preferably connect the legs 28 at a point intermediate their length. These cables are of the proper length to render the swinging frame 25 inoperable until the traveling block reaches the height shown in Figure 2. It can now be understood that upon further upward movement of the traveling block, the cables 3| will turn the frame 25 in a counter-clockwise direction about the horizontal member 26, thereby bringing the free end 21 of the frame 25 into contact with the pipe I9 and at a point intermediate the length of the pipe l9 and urge the pipe laterally of the derrick to the position shown in Figure 3. After the pipe has been positioned behind the finger 24, the crown block is then lowered sufficient to cause the lower end of the pipe l9 to rest on the cushioned portion 23 of the floor 52 of the derrick ID, the pipe l9 having been guided by manual labor to the proper position during this latter operation.
Figure 4 illustrates the position that the'frame 25 may be placed with respect to the derrick when finger 24 is of the movable type, while Figure 5 illustrates the position in which the frame 25 may be placed when the finger 24 is of the stationary type.
The operation of the device is automatic and it can be noted from the drawing that the swinging frame 25 and cables 3| operate in such a manner as to be free and clear the other movable parts of the derrick, also when the traveling block is lowered to be attached to the next stand of drill pipe, the swinging frame and cable gravitationally take their positions as shown in Figure 1 and that the cables 3| are of such length as to bring the swinging frame into operating position with the pipe I9 when the pipe 19 is raised sufiicient to clear its lower end of the hole being drilled.
While there are only certain embodiments of the invention illustrated and described, it will be apparent to those skilled in the art that certain changes, modifications, substitutions, additions and omissions may be made in the device without departing from the spirit and scope of the invention, as defined by the appended claims.
