Known pneumatic vibration exciter on author. mon. The USSR №1641735, CL 65 G 27/22, publ. in BI No. 14, 1991, containing the body placed in it a drummer and elastic cuffs, forming with the casing and drummer of the camera backward and forward movement. The back-stroke chamber made in the form of two cavities - the working and exhaust, interconnected by a by-pass channel, and the wall of the exhaust chamber are made with the exhaust channel and is interoperable with cuff camera reverse.

A disadvantage of the known pneumatic vibromassage produces a relatively small energy a single blow relative to the weight of his own drummer.

The closest analogue to the technical essence and the achieved effect is a pneumatic device for driving into the ground of long items such as pipes, RF patent No. 2149956, CL E 02 F 5/18, E 02 D 7/10, publ. in BI No. 15, 2000, containing a shock site, made in the form of a pendulum, impact weight on ball bearing suspension attached to the bracket above the hammering element node hoist drum mass, having a housing with a stepped cavity, the membrane channel for exhaust of compressed air, blocking out lower part of the stepped cavity, the plunger is placed in the stepped cavity of the body node of the lifting drum mass interoperable through the membrane with the impact mass. In the case of node hoist drum weight made the channel for supplying compressed air in the stepped cavity of the body. The rod performed stepwise, while lower his level has a transverse dimension less than the lateral dimension of the lower part of the stepped cavity of the body node of the lifting drum mass, and provided with a spring placed between the flange is wider stem and the body of the host of the rise to shock the masses. Channel for supplying compressed air to speed the body cavity is connected with the outer side surface of the same cavity. The output of the channel for supplying compressed air in a large part of the stepped cavity is made at a distance from the lower part of the stepped cavity, a smaller length greater level of stock.

The disadvantage of this pneumatic device is that the node hoist drum mass has a small stroke effective area of the membrane through which force is transmitted from the pressure of the compressed air to the percussion mass, resulting in a relatively short time of exposure to compressed air drums a lot. This causes accumulation of the impact mass of small kinetic energy and, as a consequence, the message hammered element is relatively small shock pulse, which reduces the efficiency of known pneumatic devices. In addition, the presence of a pair of slide (rod - body cavity of the host hoist drum weight) reduces the reliability of this pneumatic device due to possible jamming and wear of parts.

The technical objective of the proposed solutions is to increase the efficiency of pneumatic impact device by increasing the time of exposure to compressed air drop weight and increase reliability by simplifying controle driving into the ground rod elements, for example, pipes, drums containing mass, the smart host for the movement of the percussion mass, including the suspension of the hinge for movement of the shock mass attached to the bracket hammered over the core element and the node hoist drum mass, having a housing with a cavity which houses the switchgear, and the working chamber for compressed air, formed by the building site hoist drum weight and the membrane having an opening for the exhaust of compressed air. Building site hoist drum mass has a channel for supplying compressed air from the line and the inlet of compressed air into the working chamber of the cavity, which houses the switchgear. Shock weight installed with the opportunity to interact with the membrane and through the said openings to exhaust the compressed air in the membrane and to supply compressed air into the building site hoist drum mass - distributing device. According to the technical solution, the membrane is made in the form of a truncated cone, and a distribution device in the form of a spring-loaded valve cutoff.

In addition, switchgear, made in the form of a spring-loaded valve cutoff, has a pair of slip, which simplifies the design and, consequently, increases the reliability of pneumatic impact device.

In the second embodiment, features pneumatic impact device for driving into the ground rod elements, such as pipes, drums containing mass, the smart host for the movement of the impact mass, the host of the rise to shock the masses, having a housing with a cavity which houses the switchgear, and the working chamber for compressed air, formed by the building site hoist drum weight and the membrane having an opening for the exhaust of compressed air. Building site hoist drum mass has a channel for supplying compressed air from the line and the inlet of compressed air into the working chamber of the cavity, which houses the switchgear. Shock weight installed with the opportunity to interact with the membrane and through the said openings to exhaust the compressed air in the membrane and to supply compressed air into the building site hoist drum mass - distributing device. According to the technical solution of the membrane is performed in alausi site for movement inside the shock mass made in the form prescribed vertical pipe with cover, which is connected to the housing site lifting shock the masses.

Pneumatic impact device for driving into the ground rod elements, such as pipes, according to the second embodiment has all the advantages described above of the device according to the first embodiment in comparison with the prototype. In addition, use a smart host for movement inside the shock weight, made in the form prescribed vertical pipe with a lid, which is connected to the building site hoist drum mass, allows pneumatic impact device for driving into the ground rod elements, such as pipes, to create when working shock impulses vertical steps.

The essence of the technical solution is illustrated by the example of a specific implementation and drawings. In Fig.1 shows a General view of a pneumatic impact device for driving into the ground rod elements, such as pipes, in the first embodiment, and Fig.2. - made longitudinal section coaxially node hoist drum weight at the moment of impact by the mass of hammering the pipe in the first embodiment, and Fig.3 - the same, at the time of separation shock mass on the membrane of Fig.4 shows a General view of the pneumatic shock ustroitsy hammered on the pipe (longitudinal section); in Fig.5 - put a longitudinal section of a pneumatic impact device for driving into the ground rod elements, such as pipes, on the second version at the time of separation shock the masses from the membrane.

Pneumatic impact device for driving into the ground rod elements, such as pipes, under item 1 of the formula (Fig.1) kinetically attached to the rear end of the tube 1, hammered into the soil 2 in the horizontal direction, and contains drop weight 3 attached in the form of a pendulum using a smart host (POS. not labeled) for driving the percussion mass 3, containing the suspension 4 and the hinge 5, the bracket 6 on hammered into the ground 2 pipe 1 and node 7 lifting impact mass 3. Mount node 7 lifting impact mass 3 to the pipe 1 can be welded, but you can use a different mount. Node 7 lifting impact mass 3 has a housing 8 (Fig.2, 3) with the cover 9, forming a cavity 10, which includes a distribution device (POS. not indicated), and which can be summed channel 11 for supplying compressed air from the line. Switchgear is designed as valve 12 cutoff, provided with a compression spring 13. In the front of the housing 8 on the periphery of the fixed membrane 14 in the form of a truncated cone with a hole which can sense the camera 15. The cutoff valve 12 is installed with the possibility of interaction with the shock of mass 3 through the opening 16 in the housing 8 and the hole (POS. not labeled) to exhaust the compressed air in the membrane 14.

Pneumatic impact device for driving into the ground rod elements, such as pipes, under item 1 of the formula works as follows.

Impact of mass 3 (Fig.2) is in the upright position, the valve 12 cutoff open: to the extreme left his position on the drawing, compressing the spring 13; membrane 14 is bent to the left (in the drawing) position; the impact of mass 3 covers the hole for the exhaust of the compressed air in the membrane 14.

When compressed air on channel 11 into the cavity 10 therein is pressurized, in which the impact mass 3 moves to the right in the drawing and makes the compressed air in the working chamber 15 through the opening 16 in the housing 8. Under the action of compressed air pressure in the working chamber 15, the membrane 14 raises the impact of mass 3, which turns on the suspension 4 around the hinge 5 (Fig.1) of the bracket 6. In this case shock weight 3 accumulates kinetic energy until the full deflection of the membrane 14 to the right in the drawing, in which there is separation of the shock mass 3 (Fig.3). At the moment the hole to exhaust the compressed air in the membrane 14. At the same time under the action of the spring 13, the valve 12 cutoff blocks access of the compressed air from the cavity 10 in the working chamber 15. Next, the impact of mass 3 under the action of inertial forces continues to move up and, flying at a certain height, it returns to its original position and causes the blow hammered into the ground 2 pipe 1 through the housing 8. In this case shock weight 3 in contact with the membrane 14 seals the working chamber 15, blocking the hole for the exhaust of the compressed air in the membrane 14. At the same time the shock mass effect 3 on the valve 12 cutoff, shifting it to the left in the drawing and opening access the compressed air from the cavity 10 in the working chamber 15. Then the cycle repeats. Providing adjustment of the switchgear is carried out by screwing or unscrewing the lid 9 of the housing 8 node hoist drum mass 3.

Pneumatic impact device for driving into the ground rod elements, such as pipes, under item 2 of the formula (Fig.4) kinematically attached to the upper end of the tube 1, hammered into the soil 2 in the vertical direction. And arranged similarly to the device under item 1 of the formula, but it's a smart host for movement inside the shock mass 3 is made in the form prescribed vertical pipe 17 (figarus 8.

The device operates under item 2 is similar to the device under item 1, but providing a shock pulses vertical direction. Impact of mass 3 (Fig.4) is in the lower position, and the cutoff valve 12 is open. Compressed air flows through the channel 11 for supplying compressed air from the main line into the cavity 10, thereby creating the necessary (for lifting drums of mass 3) the pressure in it. From the lower position under the action of compressed air pressure shock weight 3 starts to move up and thereby opens the passage of the compressed air in the working chamber 15 of the cavity 10. Next, the impact of mass 3 continues to move upwards, gaining kinetic energy, up to a point where its separation from the membrane 14 (Fig.5). At the time of separation shock mass 3 from the membrane 14 is the exhaust of compressed air from the working chamber 15 to atmosphere through the hole to exhaust the compressed air in the membrane 14. At the same time under the action of the spring 13, the valve 12 cutoff blocks access of the compressed air from the cavity 10 in the working chamber 15. Impact of mass 3 flies at a certain height and fall produces a strike on hammering the pipe 1 through the housing 8 node hoist drum mass 3 (Fig.5), when it opens through the valve 12 cutoff access the compressed air from palmatogecko impact device for driving into the ground rod elements, for example, pipes, drums containing mass, the smart host for the movement of the percussion mass, including the suspension of the hinge for movement of the shock mass attached to the bracket hammered over the core element and the node hoist drum mass, having a housing with a cavity which houses the switchgear, and the working chamber for compressed air, formed by the building site hoist drum weight and the membrane having an opening for the exhaust of compressed air when the building site hoist drum mass has a channel for supplying compressed air from the line and the inlet of compressed air into the working chamber of the cavity, hosting switchgear, and shock weight installed with the opportunity to interact with the membrane and through the said openings to exhaust the compressed air in the membrane and to supply compressed air into the building site hoist drum mass - distributing device, characterized in that the membrane is made in the form of a truncated cone, and a distribution device in the form of a spring-loaded valve cutoff.
