Description

Procedure to handle and load Simultaneously drill rods and casing tubes by two independent rotating parts.

The present invention relates to a procedure to simultaneously manipulate and load rods drilling and casing tubes by two rotating parts independent.

The team is based on the possibility, due to the ability to slide along the entire length of the mast of the two upper and lower rotating end pieces of perform the charging maneuver of a piercing battery composed of drill rods and casing tubes, for drill a hole in the ground, and its subsequent recovery to lead the battery back to a state of rest in the automatic loader

To handle the rods and rods / tubes of coating on drilling machines, it is mainly used the following equipment: loaders, articulated cranes, mixed systems of cranes plus grip accessories or winch end pieces, see for example patent DE 29706264.

The equipment composed of loaders can be of the following types:

to.

frame loaders, with possibilities of stacking rods or rods and tubes lining on the mast and with a hydraulic grip of handling that removes the rod from the battery, takes it out of the frame and places it in the center of the pile;

b.

rotating loaders, with possibility of stacking the rods or rods and casing tubes over the mast and with a system for the hydraulic rotation of the arm of support or davit of the loader that grabs the rod of the frame and place it in the center of a stack;

C.

Simplified frame loaders: in some well drilling machines the frame is fixed to the mast, and the rotating part, provided with a displacement lateral, moves to pick up the rod; the advantage lies in the fact that the manipulator is not necessary, and the limitation is represented by the fact that the rods can only be ones few, two or three at most;

d.

well loaders: in well drilling machines, the frame is located in the basic machine and an arm picks up the rod and aligns it (how much The greater the number of rods, the more complex the system).

When compared to the use of double loaders or individual loaders for rods and individual loaders for pipes or both types of loaders of the rotating type, noticeable reductions in terms of weight and volumes, as well as greater simplicity of maneuver.

For the objectives indicated above, and other objectives that will be more clearly revealed to Next, the invention proposes a method for handling and simultaneously load rods and casing tubes of two independent rotating parts according to claim one.

Next, the procedure will be described. according to the invention referring to the attached drawings, in which:

- Figure 1 illustrates a drilling machine with the team that implements the procedure according to the present invention;

- Figures 2 to 5 are representations schematics of the machine of figure 1, illustrating the sequence  drilling, with simultaneous loading of rods and tubes coating;

- Figures 6 to 9 show, again schematically, the extraction sequence of only the rods; Y

- Figures 10 to 13 show again schematically, the extraction sequence of only the tubes of coating.

In figure 1, the machine according to the invention. It has essentially two rotating parts 1 and 2 slidably mounted, independent of each other, on a mast 9.

Next to the mast 9 is a loader 3 for rods 7 and casing tubes 8. How can you Observe, the loader 3 is located under the rotating parts 1 and 2 when they are at the upper end of the course.

At the bottom, fixed on the mast 9, there are three jaws 4, 5 and 6, which are necessary, as will be seen, to unscrew the rods 7 and the casing tubes 8.

First, the stage of load the coating rods / tubes in order to carry out the drilling in the ground at the necessary depth. For this first stage reference will be made to figures 2 to 5. First place, in figure 2 it can be seen that the rotating part upper 1 and lower rotating part 2 are in position upper of the mast 9, and the loader 3 is carried on the axis of rod drilling 8.

In figure 3, the two are lowered rotating parts 1 and 2 on the loader 3 and are made to rotate to in order to screw a rod to the upper rotating part 1 and the casing tube to the lower rotating part 2, being ready the rod and the casing tube in the loader 3.

In figure 4, the loader 3 is removed, leaving the rod 7 and the lining tube 8 on the shaft of drilling, suspended rotating parts corresponding.

In figure 5, rotating parts 1 and 2 they rotate the battery consisting of rod 7 and the tube of corresponding coating 8, screwed onto the rod underlying 7 'and the corresponding lining tube 8', causing it to advance, thereby drilling the earth.

As the battery dips into the ground, it is necessary to add another rod 7 with the tube corresponding coating 8 so that, with the help of jaws 4 and 5 unscrew the rotating parts 1 and 2 of the rod and casing tube protruding from the ground, being able to climb, while jaw 6 retains the tube of lining 8. The cycle starts again from the stage illustrated in figure 2 and repeated until the drilling.

Once the drilling is completed, it is necessary remove the battery of rods, including the initial rod provided of the drilling device, and the lining tubes that they contain, leaving them resting on the loader. This operation is performs in two successive stages: a first stage of extraction of the rods 7 and their placement in the loader and a second stage of extraction of the lining tubes 8 and their placement ordered in the loader.

In figures 6 to 9, the first is represented of the two stages. In Figure 6, you can first observe that the rotating part 1 has risen together with the rotating part 2, removing a first rod 7 from the casing tube 8 and, with the help of jaws 4, 5 and 6, you have disconnected it from the underlying rods. Loader 3 returns to stand alone on the drill shaft to receive the rod 7.

In figure 7, the rotating part 1 has been disconnected from the rod, and the loader 3, which has received it, He takes her to the resting position.

In figure 8, the rotating part 1 is lowered together with the rotating part 2 and, by rotating, screw on the next rod 7, which is held fixed by the gag 5.

The rotating part 1 can now rise together with the rotating part 2 while the unscrewing jaw 4 loosen the next joint, and the sequence returns to the stage represented in figure 6, from which the cycle is repeated just described until all the rods, including the device of drilling, have been completely removed.

In Figure 9, the lining tube 8 is filled with a reinforcement 10 and a cement grout or any another element that is contemplated in the project. The rotating part 1 remains high so that access to the hole is not hindered Perforated.

The rotating part 2 is maintained preferably at the top to reduce the obstacle in the work area, facilitate the unscrewing operation, and Protect it from any accidental damage.

The sequence of operation described in the Figures 6 to 9 can, however, also be done with the part swivel 2 permanently held in the lower position. In In this case, the sleeve for connecting the rotating part 2 to the casing tube must be kept out of jaws 4 and 5.

Figures 10 to 13 show again schematically the second phase of the extraction operation of the respective rods and casing tubes, that is, the extraction phase of only the lining tubes 8.

In figure 10, the rotating part 1 is up and the rotating part 2 is down, connected to the first tube of coating 8. The rods 7 are all in the loader 3.

In figure 11, the loader 3 has been carried facing up aligned with the drill rod, and the piece swivel 1 has picked up a rod 7 so that the loader 3 I can return to the state of rest.

In figure 12, the rotating part 2 has been moved up, thus covering the rod 7 with a tube of liner 8 that is disconnected from the liner tube posterior 8 ', which is retained by jaw 6.

In figure 13, loader 3 receives the rod 7 and the casing tube 8 in a coaxial position so of placing them in a state of rest.

The sequence returns to the stage illustrated in the figure 10, and the cycle is repeated until all the rods 7 are in loader 3, lined with casing tubes 8 corresponding.
