RU52443U1 - CUMULATORY PUNCH ORIENTATION DEVICE - Google Patents

Abstract

The invention relates to a device for orienting a cumulative rock drill. The technical result is expressed in increasing the accuracy of the orientation of the charges of the cumulative punch.

The claimed device contains a sleeve for the frame of a cumulative punch and differs in that at the end end of the sleeve of the frame of a cumulative punch in the diametrical plane parallel to the axis of the sleeve there are two blind cylindrical holes, in one of which there is a spring-loaded pin partially extended from the hole in its original position.

Description

The invention relates to a device for orienting a cumulative rock drill.

The closest analogue is the Orientation device of a firing punch (see, for example, the description of the invention to patent RU 2241823 7 E 21 V 43/119, E 21 V 43/117, E 21 V 47/00, E 21 V 47/02, published 2004.12. 10), including the device for turning the firing hammer after lowering into the well.

The disadvantage of the closest analogue is the inability to adjust the orientation of the charges of the firing punch due to the presence of the operation of its rotation under the influence of gravity due to the displacement of the center of mass of the firing punch.

The technical result is expressed in increasing the accuracy of the orientation of the charges of the cumulative punch.

The claimed device for providing orientation of a cumulative perforator is characterized in that the section housing contains a frame equipped with lower and upper bushings, at the end end of each of which two blind cylindrical holes are made in the diametrical plane parallel to the axis of the bush, one of which contains a spring-loaded pin, partially extended from the hole in its original position to provide adhesion to the sleeve of another section.

The essence of the claimed device is illustrated by drawings, where

figure 1 shows in section a connection of perforators;

figure 2 shows in section a connection of the rotary device to the hammer;

figure 3 shows a perspective view of a rotary device.

The device for orienting the cumulative perforator in the section housing comprises a frame 2 equipped with lower and upper bushings 1, respectively, in the lower or upper parts of the frame 2 (Fig. 1). At the end end of each sleeve 1 in the diametrical plane parallel to the axis of the sleeve 1 there are two blind cylindrical holes 4, one of which houses a spring 6 pin 6, partially extended from the hole 4 in its original position to provide adhesion to the sleeve of another section (Fig. 1 , 2).

The operation of the device is as follows. Assemble the first section of the punch, installing the frame 2 equipped with charges, detonating cord, boosters, lower and upper bushings 1, attaching an adapter 7 and a tip. The assembled first section is delivered to the well, lowered into it and fixed at the wellhead. The second section of the perforator is similarly assembled, the curb frame 2 and adapter 7 are installed in the housing 3. The second section is screwed at the wellhead with the first section. The assembly is freed from fixation, lowered into the well to the level of the wellhead and then fixed. From above, a rotary device 8 is installed on the assembly (Fig. 3). The rotary device 8 comprises, in its part, pressed against the end surface of the upper sleeve 1 of the section, two blind cylindrical holes 4, one of which houses a spring 6 spring 6, partially extended from the hole 4 in the initial position. The rotary device 8 may be provided with two handles for its rotation around the axis of the punch. The location of the holes 4 in the rotary device exactly matches the location of the holes 4 in the upper sleeve 1 of the second section. The specified arrangement of holes 4 in all bushings 1 is the same. By rotating the rotary device 8 until it clicks into the holes 4 of the spring-loaded pins 6, it engages with the upper sleeve 1 in the frame 2 of the second section of the punch. The rotation of the rotary device 8, coupled with the upper sleeve 1 in the frame 2 of the second section of the punch, rotate the lower sleeve 1 together with the frame 2 of the second section of the punch until the pins 6 fix the lower sleeve 1 in the frame 2 of the second section of the punch and the upper sleeve 1 in the frame 2 the first section of the punch. In this case, coaxiality of the charges of the first and second sections of the punch is achieved. The remaining sections of the punch are connected in series in the same way. Thus, the claimed device provides a strictly defined, predetermined coaxial arrangement of the charges of the sections of the drill. After installing and fixing the last section of the puncher according to the mark on the rotary device 8, make a mark on the housing 3 of the last section of the puncher, indicating the direction of the cumulative charge stream of the entire assembly of the punch.
