Description

The utility model relates to the field of devices for the extraction of oil, gas, water, and in particular to the details of a cumulative perforator.

Known holders of a cumulative charge in the frame of a punch, containing a body with a cylindrical and conical parts, with a node for fixing the detonating cord (see, for example, the description of the invention to Eurasian patent 011537, IPC ЕВВ 43/117, publication date 04/28/2009; description of the invention to US patent 7347279 B2, IPC ЕВВ 43/116, publication date March 25, 2008).

The main disadvantage of similar devices is the lack of effectiveness of the fixation of the cumulative charge in the frame of the casing punch.

The closest analogue of the claimed technical solution is the holder of the cumulative charge in the frame of the punch, containing a body with a cylindrical and conical parts, with a node for fixing the detonating cord (see, for example, the description of the utility model for patent RU 102055, IPC ЕВВ 43/117, publication date 02/10/2011).

The disadvantage of the closest analogue is the lack of effectiveness of the fixation of the cumulative charge in the frame of the casing punch.

The technical result is to increase the efficiency of fixation of the cumulative charge in the frame of the casing punch.

The essence of the claimed technical solution is characterized in that it contains a housing with a cylindrical and conical parts, with a node for fixing the detonating cord, and differs from the closest analogue in that diametrically oppositely located cutouts are made in the side walls of the conical part of the body, on the outer side of the upper edge of the cylindrical protrusions are made of the body part, and stops are located under them, at least four slots are made in the upper edge of the cylindrical part of the body, between which L-shaped clamps are connected to the cylindrical part of the housing, the fixing elements of which are directed inside the cylindrical part of the housing.

The essence of the technical solution is illustrated by the drawing.

The holder of the cumulative charge in the frame of the casing punch, contains a casing with a cylindrical part 1 and a conical part 2, with a node 3 for fixing the detonating cord 4. In the side walls of the conical part 2 of the casing there are diametrically opposed cutouts 5 (Fig. 1). On the outer side of the upper edge of the cylindrical part 1 of the casing, protrusions 6 are made, and under them are the stops 7, in the upper edge of the cylindrical part 1 of the casing, at least four slots are made, between which are L-shaped, connected to the cylindrical part 1 of the casing latches 8, the fixing elements of which are directed inside the cylindrical part of the housing (Fig. 1, 2, 3, 4, 5).

The internal dimensions of the cylindrical part 1 of the housing and the conical part 2 of the housing are determined by the external dimensions of the cumulative charge 11 installed in the housing (FIGS. 2, 3, 4, 5).

The internal dimensions of the recess in the node 3 for fixing the detonating cord 4 are determined by the external dimensions of the detonating cord 4 to ensure that it is pressed against the cumulative charge 11 after assembly.

The upper edge of the cylindrical part 1 of the housing is made curved and corresponding in shape to the outer cylindrical surface of the frame 12 of the housing punch.

To ensure the installation of a cumulative charge 11 in the casing of the holder with external dimensions smaller than the internal dimensions of the cylindrical part 1 of the casing and the conical part 2 of the casing, an adapter sleeve 9 can be installed in the cylindrical part 1 of the case, having a protrusion 10 in the upper part directed towards the inside of the adapter sleeve 9 (Figs. 4, 5).

The holder of the cumulative charge 11 in the frame 12 of the casing punch is used as follows.

The holder of the cumulative charge 11 is mounted in the holes of the frame 12 of the case punch with fixing its position in the holes of the frame 12 by means of the protrusions 6 and the stops 7 of the cylindrical part 1 located below them (FIGS. 2, 3). In the recesses of the nodes 3 for fixing the detonating cord 4, the detonating cord 4 is laid, previously pulling it through the cutouts 5 of the conical part 2 of the body. The cumulative charge 11 is installed in the cylindrical part 1 and the conical part 2 with fixation of its position by means of L-shaped clamps 8, which, when the cumulative charge 11 is installed, are elastically bent and then, when the cumulative charge 11 is fully installed, they return to their original position with the edge of the cumulative charge 11. Curb frame 12 with cumulative charges 11 and detonating cord 4 is installed in the housing 13 of the housing punch so that the cumulative charges 11 are located opposite the recesses in the housing e perforator housing 13 (the so-called skellopov).

If it is necessary to install cumulative charges 11 of smaller dimensions in the holder of the case perforator in the frame, they preliminarily put on the adapter sleeve 9 with a protrusion 10 in the upper part, by which the position of the cumulative charge 11 is fixed after installing the adapter sleeve 9 in the cylindrical part 1 of the holder body.

If necessary, the cumulative charge 11 is removed in the reverse order to the above. In this reverse process, the L-shaped latches 8 are squeezed out and the cumulative charge 11 is removed. After removal of the detonating cord 4 by deformation of the upper edges of the cylindrical part 1 of the housing, the protrusions 6 and the stops 7 are disconnected from the frame 12 and the cumulative charge holder can be removed from the frame 12 of the housing punch.
