1 is a front view showing a composite swivel device according to an embodiment of the present invention. According to Figure 1, the connecting portion 12 is installed to couple the rotary shaft to the kelly bar system. An empty space is formed inside the rotating shaft so that air is introduced therein, and the empty space is called an air chamber. Although not shown, a swivel is installed in the lower part of the kelly bar, and the connection part 12 couples the swivel and the rotating shaft.

The rotating shaft is installed inside the case 14. The case 14 prevents the case from being damaged due to the excavation work, and is coupled with the guide 16 so that components other than the rotating shaft do not rotate and remain fixed. Therefore, the air inlet and the discharge passage 28 are maintained at a fixed position without being affected by the rotation of the rotary shaft.

2 is a cross-sectional view showing the configuration of a composite swivel device according to an embodiment of the present invention. According to FIG. 2, a connection part 12 for coupling the swivel device to the lower part of the kelly bar is formed. The connection part 12, the case 14, and the guide 16 remain fixed without being rotated, and are coupled to a rotating shaft 18 formed inside the case 14 and a lower portion of the rotating shaft 18. The working tool 36 is rotated to perform a necessary work including an excavation work, thereby serving as a swivel device.

The air which flows in through the air inlet 22 from the air compressor installed on the ground is supplied to the work tool 36 via the rotating shaft 18. The work tool 36 is coupled to the lower portion of the inlet 30 of the discharge passage 28, and like the swivel device is formed inside the air chamber space, can be used interchangeably according to the work. In addition, the inlet hose 26 is installed to move the air introduced into the air chamber 20 formed in the rotating shaft 18 to the work tool 36. As the inlet hose 26 is connected, the work tool 36 can smoothly supply compressed air even when the work tool 36 descends to the basement while performing an excavation or other work.

Air introduced into the work tool 36 discharges the excavated residue to the outside through the outlet 32 through the inlet 30 of the discharge passage 28. A sealing device 34 is installed outside the rotating shaft 18 so that the residue does not flow into the air chamber 20.

The guide 16 is formed to surround the case 14, and is fixedly coupled to the case 14 and the discharge passage 28 to maintain the fixed position even when the rotation shaft 18 rotates.

Figure 3 is a cross-sectional view showing a cross-section of the discharge passage of the composite swivel device according to an embodiment of the present invention from the top. According to FIG. 3, the rotating shaft 18 rotates with the inlet port 30 and the outlet port 32 maintains a fixed position.

The rotary shaft 18, the upper portion is coupled to the kelly bar 44 by the connecting portion, the lower portion is coupled to the work tool 36. Accordingly, the rotation shaft 18 rotates together with the work tool 36. Inlet 30 also rotates with the rotating shaft to facilitate the discharge of excavation residue.

The air chamber 20, which is a space between the rotating shaft 18 and the inlet 30, remains closed, and one side of the rotating shaft 18 is opened to connect the inlet 30 and the outlet 32. Since the outlet 32 is empty, the connection passage with the inlet 30 is secured even when the rotary shaft 18 rotates, so that the cross-sectional area of the discharge passage of the excavation residue is kept constant.

Figure 4 is a state diagram showing the use of the composite swivel device according to an embodiment of the present invention. According to Figure 4, the composite swivel device of the present invention is installed on the lower part of the kelly bar 44 of the drilling rig is used dry.

The connection part 12 is installed in the lower part of the kelly bar 44, and is coupled to the case 14. The connection part 12 and the case 14 remain fixed without rotation, and the guide 16 moves along the wall of the excavation point and serves to assist the case 14 not to rotate.

The work tool 36 coupled to the rotating shaft and installed under the case 14 may be used by being replaced according to the required work content. When the work tool 36 rotates, the rotating shaft 18 rotates together. Although not shown, an air chamber is formed so that air is also introduced into the work tool 36, and residues generated during excavation are introduced into the air chamber. Then, the air introduced into the air chamber of the work tool 36 from the air compressor 24 installed on the ground, discharges the excavated residue to the outlet 32.
