Description

The invention relates to a mountain spruce, in particular, to drilling mechanisms for eliminating sticking of a drilling rig, a projectile using a drive of rotational action, 5

The purpose of the invention is to increase the reliability and efficiency in the operation of the vibrator.

Figure 1 shows a jibrator, a longitudinal section; in Fig.2 a section aa in Fig.1; on fig.Z - section BB in figure 1; figure 4 - section bb In figure 2.

The vibrator comprises a housing 1, anvil 5 of the shaft 2, a lower cover of the adapter 3, a shaft 4, in the upper part of which an adapter 5 is fixed for connection with a shaft-driven drive. Inside the shaft 4, the channel 6 dL of the supply of washing liquid to the stuck one is complete; The gears on the shaft 4 are mounted on a gear coupling half 8, which rests on the thrust bearing 9. The head of the vibrator is made in the form of two rigidly connected rings 10 and II, having the same outer diameter and different internal ones. In ring II, three or more depressions 12 are made under the rollers 13, which are mounted 30 on the axles 14. The pins 15 serve to prevent the axes from moving. The vibrator heads are constantly pressed against the anvil. 2 by springs 16. In cover 3, screws 17 are installed, which, through clamping washer 18, serve to press in springs 16. Anvil 2 and vibrator cap 3 are fastened with three or more bolts 19, which are also guides for movement 40 of the striker. For this purpose, longitudinal holes are made in the striker. Between the rings 10 and 11 of the striker are connected by bolts 20. In the end recesses 21 and 22 of the strikers are the axes 14 of the rollers. 45 The lower part of the shaft 4 is imprinted as

shank 23 with grani mi. In the cover 3 there is a recess 24 for the tails. Aa 23. The sealing element 25 is designed to prevent the leakage of the washing liquid and its penetration into the vibrator. The cavity 26 formed by the rings 10 and 11 and the recesses 12 are filled with grease.

The vibrator works as follows.

The adapter 5 connects the vibrator to the rotational feeder of the drilling machine, and the cover adapter 3 is directly or via a fishing tool with stuck projectiles. For the joint with the stuck projectile, the shaft 4 is lowered to the lower position, while the faces of the shank 23 23 enter into the notches 24 of the lid 3 and rotate it until it is joined to the stitched side. After connecting the vibrator with the stuck snar dom realizatsii-. are the tension of the projectile. In doing so, the shank 23 emerges from the recess 24 and provides the freedom to rotate the shaft. The rotation of the shaft 4 (in the direction of the arrow, H. in FIG. 3) through the splines 7 is transmitted a tooth-like semi-coupling 8, which, interacting with the rollers 13, pushes the vibrator's boom downwards. With further rotation, the rollers 13 slide into the recesses , the teeth and, pressing the springs 16, the striker strikes the anvil 2. Through the bolts 19 or through the body, the blow from the anvil 2 is transferred to the adapter 3 and then to the next gear.

The magnitude of the recess between the teeth of the half coupling and the height of the ring 10 of the striker are chosen in such a way as to exclude the transfer of impact on the rollers 13 and the toothed coupling half.

At the same time, the impact of vibration and axial load ensures the elimination of stuck projectiles and removing it from the well.
