In this case, oblique sliding protrusions are formed on outer surfaces of both sides of the sliding bit of the second inner hammer, and oblique guide grooves are formed on both inner surfaces of the rotating body corresponding thereto.

In addition, a bearing is installed between the outer surface of the rotating body and the inner surface of the outer case to achieve a smooth rotation with each other.

In addition, the driving means is a hydraulic motor to obtain a rotational power by the hydraulic pressure, a reducer connected to the rotating shaft of the hydraulic motor, and a shoe bell for operating the piston by supplying air to the first and second inner hammer inside the rotor when driving It is made, including.

Hereinafter, a preferred embodiment of the present invention looks at in more detail based on the accompanying drawings.

1 is a side cross-sectional view showing a horizontal hammer propulsion combination hammer to which the present invention is applied, Figure 2 is a flat sectional view showing a horizontal hammer propulsion combination hammer to which the present invention is applied, Figure 3 is a horizontal pipe propulsion applied to the present invention 4 is a side cross-sectional view showing a state in which the combination hammer for horizontal pipe propulsion to which the present invention is applied is separated.

The combination hammer for horizontal tube propulsion of the present invention has a large diameter outer case, a rotating body rotated inside the outer case, first and second inner hammers coupled to the rotating body, as shown in FIGS. It consists of a driving means for rotating the rotating body and a pump for discharging the ground discharged through the rotating body to the outside.

Thus, the outer case 100 is formed to have the same size as the diameter of the horizontal pipe to be constructed is itself fixed without being rotated.

The rotor 200 is rotated in close contact with the inner surface of the outer case 100, and the bearing 220 is installed between the outer case 100 and the rotor 200 for smooth rotation thereof. Preferably, the bearing 220 is formed to be separated together when the rotating body 200 is separated.

Meanwhile, the first and second inner hammers 300 and 400 are coupled to the front surface of the rotating body 200, and discharge grooves 240 are formed on the outer surface of the rotating body 200 at equal intervals. The ground excavated by the 1, 2 inner hammer is formed to be smoothly discharged through it.

The first inner hammer 300 is installed at a position eccentrically to the one side from the center of the rotor 200, in this case within the head rotation radius of the bit 360 coupled to the front end of the first inner hammer 300 Is formed so as not to depart from the radius of rotation of the rotating body (200). That is, when the rotating body 200 is separated, the bit 360 of the first inner hammer 300 is formed so as not to be caught by the outer case 100.

On the other hand, the first inner hammer 300 coupled to the rotating body 200 is a bit 360 to the bit fixing ring 340 in a state in which the bit fixing ring 340 is coupled to the front end of the inner case 320 usually ) Is coupled to the inner case 320, the piston 380 is installed to hit the bit 360 by the air flowing through the shovel 560 to be described later. Therefore, the bit 360 is coupled to allow a predetermined interval flow in the front and rear direction by hitting the piston 380 when combined with the bit fixing ring 340, as well as the ground in front of the head of the bit 360 A plurality of buttons 360 ′ are formed to protrude from the rock while scraping them.

The second inner hammer 400 is installed eccentrically to the other side of the first inner hammer 300 of the rotating body 200, in which the front end of the second inner hammer 400 is oblique when contacted with the ground by excavation Sliding bit 460 is formed so that the outer case 100 is wider than the rotation radius while reversing in the direction.

That is, the sliding bit 460 is wider than the outer diameter of the outer case 100 when the ground is excavated to enable smooth advancement of the outer case 100 and the horizontal tube, while the rotating body from the outer case 100 is rotated. When the 200 is removed, since the sliding bit 460 is received in the rotational radius of the rotating body 200 while moving in an oblique direction, the separation of the rotating body 200 is smooth without being caught by the outer case 100. It becomes possible.

Thus, as a configuration for the sliding bit 460 of the second inner hammer 400 is moved forward and backward in an oblique direction, the sliding protrusion 462 in the diagonal direction is formed on both outer surfaces of the sliding bit 460 and corresponding thereto Diagonal guide grooves 260 are recessed on both inner surfaces of the rotor 200.

On the other hand, the second inner hammer 400 is coupled to the rotating body 200 is a sliding bit (b) to the bit fixing ring 440 in a state where the bit fixing ring 440 is normally coupled to the front end of the inner case 420. 460 is coupled and the piston 480 is installed inside the inner case 420 to strike the sliding bit 460 by the air flowing through the shovel 560 to be described later. Thus, the sliding bit 460 is coupled to the bit fixing ring 440 to allow a certain interval flow in the front and rear direction by hitting the piston 480, as well as in front of the head of the sliding bit 460 A plurality of buttons 460 ′ are formed to protrude the rock while scraping the ground.

The driving means 500 is formed to rotate the rotor 200 in a state fixed to the rear of the outer case 100. That is, the drive means 500 is a reduction gear 540 is connected to the rotary shaft of the hydraulic motor 520 to obtain the rotational power by the hydraulic pressure to increase the rotational force of the hydraulic motor 520 to the rotating body 200 The piston 380 of the first and second inner hammers 300 and 400 by supplying air into the rotating body 200 which is rotated by the power of the hydraulic motor 520 and the reduction gear 540 while being configured to transmit. 440 is configured to operate the 480.

In this case, the driving means 500 is fixed to the rear of the outer case 100 while the excavation work is performed, while the driving means 500 is separated from the outer case 100 when the rotating body 200 is separated. It works smoothly in a detached state.

The pump 600 is configured to suck the ground discharged through the discharge groove 240 of the rotating body 200 to discharge to the outside.

Excavation work is performed by the bit 360 and the sliding bit 460 of the first and second inner hammers 300 and 400.

At this time, the first and second inner hammers 300 and 400 are supplied with air through the shovel 560, so that the respective pistons 380 and 480 act to hit the bit 360 and the sliding bit 460, respectively. While excavating the ground or rock more efficiently, and the sand or gravel generated in the excavation is discharged to the rear through the discharge groove 240 of the rotating body 200, the ground discharged to the rear as described above It is discharged to the outside through the pump 600.

On the other hand, in the state in which the bit 360 or the sliding bit 460 is damaged by such an operation, the worker enters into the horizontal tube to remove the flange and the pump 600 supporting the driving means 500. The rotary body 200 is separated from the outer case 100 at this time, wherein the sliding projection 462 of the sliding bit 460 is advanced along the guide groove 260 of the rotating body 200, the sliding bit As the 460 is accommodated inside the outer case 100, the separation is possible.

Therefore, according to the configuration of the present invention as described above when the horizontal excavation of the ground does not use the propulsion screw (1) having a relatively low lateral force is possible long-distance excavation, while the ground crushed during the excavation is outcase (100) Discharged to the outside through the pump 600 installed inside).

As described above, the present invention has been described with reference to the embodiments illustrated in the drawings, but this is merely exemplary and will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. will be. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
