The present invention relates to the field of construction equipment and is intended mainly for diving into the ground metal pipes, primarily for the trenchless laying of underground utilities.

Known pulse pneumatic device for plugging pipes.with. The USSR №1036857, IPC E02F 5/18, publ. in BI No. 31 for 1983), which includes a housing with a drummer, the air-distributing mechanism and coupled with the housing head part. Shock pulse transmitted by the drummer of the head part of the device, passing through the housing is transmitted to the pipe and provides high efficiency of the immersion pipe. The disadvantage of this device along.with. No. 1036857 is that part of the pulse while passing through the body consumes its deformation. In addition, the case of the known device is experiencing significant tensile stress, due to the fact that the housing is attached to the tail pipe and the blow on the head part. This greatly reduces the durability of the case.

Closest to the present invention is a device for sinking pipes into the ground (RF patent No. 2135692, IPC E02D 7/02, E02F 5/18, publ. 27.08.1999), including housing, are accommodated in the housing drummer and mating with the housing head part. While pairing the head part with the body made with the possibility of separation at the moment of impact and after the respective connection through a pull-up element.

This embodiment of the device provides for the removal of the impact load from the chassis and the transmission of the shock pulse directly from the head part to the pipe. This increases the efficiency of the immersion pipe and the durability of the case.

The disadvantage of this device by the RF patent №2135692 is the occurrence at the moment of impact of the gap between the casing and the head part. When this occurs, the leakage of compressed air from the chamber idling, which slows down the movement of the striker at idle and, therefore, reduces the efficiency of the device.

The technical problem solved by the invention is the improvement of efficiency of immersion tubes with increasing resource device.

The problem is solved in that the device for immersion in the soil pipe, comprising a body accommodated in the housing drummer, coupled with the housing head part and the means for restricting movement of the head part relative to the housing is further provided with an elastic element installed between the body and the head part, and the pair head part with the body is made with a backlash.

The pairing of the head part of the housing with a gap ensures the removal of the impact load from the housing and mounted between the body and the head part of the elastic element provides an air tight chamber idling is simultaneously dampens shock loads on the body. All of the shock pulse is transmitted from the head part to score the pipe, and the movement of the striker at idle is not slowing down, which leads to increasing the effectiveness of the immersion pipe. At the same time increase the resource of the device due to the fact that the shock pulse is spent only on useful work and no load on the body.

For more reliable sealing of the camera idling and removal of shock loads from the hull of suitable elastic element is installed with advanced preload.

Suitable means limiting the movement of the head part relative to the body to perform in the form of rods, closing connection head part with the body. This will keep the high efficiency of the device with the simple technology of its production, which contributes to the solution of a technical problem.

Suitable means limiting the movement of the head part relative to the body to perform in the form of radial grooves on the outer surface of the shell, the response she radial grooves on the inner surface of the head part and movably installed inside the track grooves of the rolling balls. This embodiment will provide compactness while maintaining the high efficiency of its work, which also contributes to the solution of the set t is nicesly tasks.

The invention is illustrated by drawings, where Fig.1 shows a longitudinal section of the device with means for limiting the movement of the head part relative to the body in the form of rods, closing connection head part with the case of Fig.2 is a longitudinal section of the device with means for limiting the movement of the head part relative to the body in the form of spherical grooves in the body and the head part and movably mounted in the grooves of the ball.

Device for immersion in the soil pipes (Fig.1, figs.2) includes a head part 1, building 2, which is installed inside the drummer 3, striking at the head part 1. The connection head portion 1 body 2 is made with a gap, and moving the head part 1 relative to the housing 2 is limited by the tool 4. Between the head part 1 and the housing 2 has an elastic element 5. Compressed air to the device is supplied via the duct 6. The device head part 1 is rigidly attached to score the pipe 7.

Tool 4 restrict the movement of the head part 1 relative to the housing 2 may be made in the form of rods 8, closing connection head part 1 with the housing 2 (Fig.1).

It is also possible execution means 4 restrict the movement of the head part 1 relative to the housing 2 in the form of radial grooves 9 on the outer surface of the housing 2, the response she radial ditches and 10 on the inner surface of the head part 1 and movably installed inside the grooves of the raceway balls 11 (Fig.2).

The proposed device operates as follows.

Under the action of compressed air supplied through the duct 6, drummer 3 makes reciprocating movement in the housing 2 and strikes the head part 1 of the device, forming in her shock pulse of a certain amplitude and duration. Through the head part 1 shock pulse is transmitted to the butt hammered pipe 7, through the immersion pipe 7 into the ground. As the pair head part 1 and the housing 2 is made with a gap, and between the body 2 and the head part 1 has the elastic element 5, shock pulse is not transmitted to the housing 2, and, passing through the head part 1 is transmitted to score the pipe 7, while retaining its amplitude and duration, which contributes to the effectiveness of the immersion pipe and to increase the service life of the housing 2. Tool 5 restricts the movement of the head 1 relative to the housing 2, preventing the departure of the head part 1 of the housing 2.

In the case of execution means 4 in the form of rods, moving the head part 1 relative to the housing 2 is limited by the length of the rods 8.

In the case of execution means 4 in the form of radial grooves 9 on the outer surface of the housing 2 response she radial grooves 10 on the inner surface of the head part 1 and movably installed inside the grooves of the raceway balls 11, the moving head is Asti 1 relative to the housing 2 is limited by the size of the gap between the walls of the grooves 9 and 10 and the outer surface of the balls 11.

After the strike on the head part 1 drummer 3 starts to move in the opposite direction under the action of pressure in the chamber idling 12. Due to the elastic element 5, the pressure in the chamber idling 12 remains the same as at the time of the attack, and movement of the striker 3 in the reverse direction is not slowing down.

Then the cycle of device operation is repeated until the immersion pipe 7 into the ground by a specified amount.

After immersion pipe 7 into the ground, the device switches to the reverse mode. The drummer begins to strike the rear end of the body 2, making it move in the opposite direction. Due to the rods 8 or balls 11 in the same direction occurs and the movement of the head part 1. When the head part 1 is released from the pipe 7.
