Appl. No.:

10/102544

Inventors:

Thomas D Hauk - Los Alamitos CA
Raul Hector Perez - Hawthorne CA

Assignee:

Hawk Industries, Inc. - Long Beach CA

International Classification:

B25B 1700

US Classification:

81 5716, 81 5724, 81 5734

Abstract:

A pipe making and breaking apparatus having top, middle and bottom wrenches connected to a frame. A torquing cylinder operatively extends between the middle wrench and the frame and when actuated through one or more torquing cycles causes an upper pipe to make (top and middle wrenches) or break (middle and bottom wrenches) relative to a lower pipe. A grip hold actuator maintains the middle wrench in the gripping position continuously during the making torquing cycles. A continuous chain spinner above the top wrench spins the top pipe to make a position or away from a make position. The spinner can be a stand alone unit or can hang freely in the derrick or can be part of the make/break apparatus. A spinner drive chain motor when pressurized and when an oiler button is actuated causes lubricant to be sprayed out a nozzle on the (moving) chain. Windows (guide gates) and/or guide posts direct the chain so as to not bunch up against the casing sprockets.

US Classification:

74 63, 418 611

Abstract:

A transmission system for transmitting a rotary motion input to a rotary motion output utilizing hypocycloid motion multiplication is disclosed. The system comprises an input mechanism, at least one hydraulic transmission means, an output mechanism and an output bladder linkage. The input mechanism includes a plurality of rollers that each capture at least one arcuate linkage against an inside surface of a cylindrical hub, causing the linkage to rotate as the roller traverses thereacross and compress one of a plurality of input bladders. The compressed input bladders cause an output bladder to expand to drive the output mechanism in reciprocal linear motion, which the output mechanism converts to rotational motion at the rotary motion output. The output mechanism can be located proximate to, or distal from, the input mechanism.

US Classification:

81 5716, 81 5715, 173 1

Abstract:

A self-adjusting spinner is provided that is capable of accommodating various pipe sizes without requiring the need for an operator to climb up the support mechanism and manually change the position of the drive assembly. The self-adjusting spinner includes a case having two pivotally connected members: a stationary case member and a moving case member. Upper and lower plates having gear racks are mounted on the stationary case member for moving a drive assembly horizontally across the case. The drive assembly includes a motor that drives gear sprocket through a drive shaft. The drive sprocket then drives a chain that rotates a drill pipe in an operative position relative to the case. The spinner also includes an adjusting assembly mounted on the case that moves the drive assembly along the gear rack upon the actuation of an adjustment sequence. When the adjustment sequence is initiated, the effective length of the chain is adjusted to accommodate drill pipes of varying diameters.

Abstract:

A method for estimating the size and location of couplings within a waveguide directional coupler is provided. The method is applied to a waveguide directional coupler having a main transmission waveguide connected to an auxiliary transmission waveguide by a plurality of bore hole couplings. The bore hole couplings are in the interior of the waveguide directional coupler and, therefore, are not easily measurable. The invention provides a simple and inexpensive method for measuring the size and location of the couplings without dismantling or destroying the waveguide directional coupler. The method generally includes the steps of applying a two-sided tape to a member, inserting and securing the member within the main transmission waveguide, with the two-sided tape adjacent to the bore hole couplings, pouring a fine particulate substance such as talc into the auxiliary transmission waveguide such that a portion of the talc enters the bore hole couplings and adheres to the two-sided tape, and withdrawing the member such that the size and location of the bore hole couplings can be determined by measuring the size and location of marks on the two-sided tape caused by the fine particular substance adhering to the two-sided tape. In this manner, the dimensions of the bore hole couplings within the waveguide directional coupler are easily determined without the need for dismantling or destroying the waveguide coupler, and without the need for any expensive X-ray techniques.
