4 Claims.
This invention relates to drilling machines, and particularly to what is commonly known as a churn drilling device, an object being to provide a strong and simple construction wherein the weight of the walking beam structure acts to produce a smooth running action of the machine.
Another object of the invention is to provide a simplified arrangement wherein the spudding sheave is moved up and down with the walking beam through the action of a pitman and crank members coacting therewith.
An additional object is to provide a drill structure wherein the weight of the walking beams, spudding sheave and associated parts act to counterbalance the drilling tubes.
In the accompanying drawings:
Fig. 1 is a side view of a drilling machine disclosing an embodiment of the invention;
Fig. 2 is a transverse sectional view through Fig. 1 approximately on the line 22;
Fig. 3 is a sectional view through Fig. 1 approximately on the line 33, the same being on an enlarged scale.
Referring to the accompanying drawings by numerals, I indicates a pair of skids or runners on which a frame 2 is mounted. A sub-frame 3 is mounted on frame 2 at the rear part as shown particularly in Fig. 1. These frames may be braced, if desired, by suitable braces, and to frame 2 is connected the tower 4 having tower bracing beams 5. This tower structure forms what is commonly known as a derrick and has a crown sheave 6 at the upper end so as to accommodate the drill rope I. The drill rope or cable I is adapted to have any desired kind of drilling tools connected at the lower end outside of the frame 2 while the opposite part passes over the spudding sheave 8 and thence to the drum 9. .By rotating the drum 9 in one direction the cable I may be taken in when it is desired to raise the drilling tools. When itis desired to lower the drilling tools the drum 9 is released and the weight of the tools will allow the cable to pay out.
In order that the drill or drilling tools may be raised and lowered in the usual manner of a churn drill, the spudding sheave 8 is freely rotatable on the spudding shaft II] which is journalled in suitable bearings H- and I2 on the walking beams I 3 and 54. These beams are pivotally mounted at the rear end on. the intermediate shaft I5 which is journaled in suitable journal members 16 and i1 mounted on the subframe 3. The spudding shaft l extends through bearings H and I2 and has the respective cranks lS-and l9 keyed or otherwise rigidly secured thereto, said cranks being parallel and in alignment with each other. Pitmans 20 and 2! have their upper ends connected to the respective cranks and their lower ends pivotally connected at 22 and 23 respectively to the respective brackets 24 and 25 rigidly secured to frame 2. By this construction it will be readily seen that whenever shaft l0 rotates the'cranks and pit mans will function and cause the walking beams l 3 and It to swing upwardly and downwardlyand cause the spudding sheave 8 to swingupwardly and downwardly.
A comparatively large sprocket wheel 26 is rigidly secured to the shaft i ii and accommodates a chain 2'! which passes over a small sprocket wheel 28 rigidly secured to shaft 15. Whenever shaft I is rotated power will be transmitted through the chain 21 tosprocket wheel 28 and to shaft ID for causing the walking beams and associated parts to function. In order. that the shaft may rotate when desired the' same is connected through a clutch 29 to a comparatively large pulley wheel 36 actuated by the belt 3! passing over the small pulley wheel 32 rigidly secured to the shaft 33 that is driven by the motor 34. If the motor 34 is a gasoline engine or Diesel engine the shaft 23 might be an extension from the crank shaft of the engine. However, as far as the present invention is concerned the engine or motor 34 continually rotates shaft 33 while it is functioning. Also the motor or engine 34 continually rotates the shaft 35 while functioning.
When it is desired to wind cable I, brake band 42 is loosened and clutch 36 is caused to function, whereupon power will be transmitted to the drum 6 while rotating the same in such a direction as to wind the cable. When it is desired to feed out this cable, brake band 42 is loosened more or less so as to allow the Weight of the drills and other parts to cause the drum 9 to unwind the cable. After a sufficient amount has been payed out the brake band 42 is tightened and the catch 59 caused to engage in the proper notch in rack 46 to lock the parts against further movement. Clutch 29 is moved to a closed or open position by the control rod 53. It will be noted that all of the pull rods extend to-the forward end of the machine so that they may be operated by anyone who is standing at the front of the machine. When the control rod 53 is rocked in one direction clutch 29 is functioning to cause the shaft 15 to rotate, and when moved in the opposite direction power is disconnected from shaft l5 even though pulley 3H and associated parts are still functioning.
During the ordinary drilling operation shaft 4! is stationary while shaft ['5 is rotating whereby the drills are moved upwardly and downwardly. Ihe distance of movement of the drills is regulated by the length of the cranks i8 and I9. It will also be noted that the drills are moved upwardly and downwardly positively by reason of the cranks just mentioned, and in addition the downward movement is augmented by the weight of the walking beams, spudding sheave and associated parts whereby a smooth uniform action is secured without the addition of any further weight,
It will be understood that any kind of an engine or motor may be used as motor 34, and when the motor is functioning shafts 33 and 35 will be continually rotating. From these two shafts power is taken off to operate the respective parts either simultaneously or at different times. The shaft I5 usually is functioning most of the time while shaft 4| is usually stationary most of the time and is only moved from time to time to change the position of the drilling tools.
