Description

Excavation apparatus using a vibrating rotating body {Rock excavation apparatus using vibrating rotating body}

The present invention relates to an excavation apparatus, and more particularly, to an excavation apparatus using a vibrating rotor capable of crushing an excavation or arm by vibrating a vibrating rotor for excavation in a rotational direction.

In general, in the construction industry, the ground is excavated for the purposes of construction of foundations, drilling, tunneling, underground structure construction, earth wall construction, etc., and most of the excavation is required for rocky ground. In addition, as urban infrastructure, the open-cut method has been implemented when various pipelines are reclaimed and underground tunnels are constructed.

An auger device and a drilling machine for excavation are used for excavation of the ground, and there are mud hammers, rotary pipe excavators, self-propelled excavators, etc.

Korean Patent Registration No. 10-1587276 discloses a large-diameter drilling device and a tunnel excavation method using the same, and Korean Patent Publication No. 2014-0081448 discloses a rock excavator, and Korean Patent Publication No. 2011-007347 The arc has a rig posted.

The posted excavation apparatus includes a hammer installed movably inside the casing to provide rotational force and striking force, and a hammer installed at the lower end of the hammer to receive rotational force and striking force from the hammer to strike the ground, and high-pressure air inside It includes a bit through which the suction passage is formed.

Such an excavation device has a problem in that it cannot provide a continuous striking force to the excavation site because the bit of the hammer is crushed and excavated by hitting the excavation site while ascending and descending in the vertical direction. The striking force acting in the vertical direction crushes the arm of the excavation part, but in this process, the reaction force acts and it cannot give the striking force in the rotational direction. This has a problem of relatively lowering the crushing force in the rotational direction.

And in the case of an auger device among excavation equipment, excavation is made while the screw pile rotates. This makes it difficult to crush the arm on the transport trajectory of the drilling hole because it cannot apply an impact force to the screw pile in the rotational direction.

The operation of the excavation apparatus using the vibrating rotating body according to the present invention configured as described above will be described as follows.

In order to crush the excavation or arm using the excavation device 10 using the vibrating rotating body according to the present invention, the coupling bracket 11 is coupled to the boom of the construction machine using a separate coupler. A tool for drilling or crushing the arm is selected and mounted in the excavation apparatus 10 using the vibrating rotating body. And the excavation apparatus 10 using the vibrating rotating body is adjusted to a position for excavation or crushing.

During this process, the first driving motor 75 of the rotational driving unit 70 of the vibrating rotating body 20 is driven to rotate the vibrating rotating body 40, and the second driving of the vibrating rotating unit 50 is By driving the motor 51, the vibrating rotating body 40 vibrates in the rotational direction and the reverse direction thereof.

The rotation of the vibrating rotating body 40 is made by the rotation driving unit 70, which drives the first driving motor 75 of the rotation driving unit 70 to rotate the pinion gear 76 connected thereto. As the meshed ring gear 72 rotates, the vibrating rotating body 30 rotates with respect to the support frame 20 .

And the generation of vibration by the vibration generating unit 50 is by driving the second driving motor 51 of the vibration generating unit 50 by driving the driving shaft 52 connected to the motor shaft of the second driving motor 51 Accordingly, driven gears 63 and 64 radially arranged by the driving gear 53 rotate.

In this way, the eccentric weights 65 installed on the first and second driven gears 63 and 64 or the first and second driven shafts 61 and 62 are rotated to generate vibration.

Since the vibration generated in this way rotates in a state in which the eccentric portions 65a of the eccentric weights 65 are aligned to face the rotational direction, the vibration is strongly made in the direction opposite to the rotational direction.

To explain this in more detail, the eccentric weight ( 65) is located on the corresponding side, so the vibration energy is canceled out in the radial direction.

And when the eccentric part of the eccentric weight 65 is positioned in the rotational direction as the driving shaft 52 and the driving gear 53 installed thereon rotate by the second driving motor 51, kinetic energy according to the rotation of the eccentric weight That is, the vibration energy acts in the rotational direction of the vibrating rotating body 40 . Therefore, the excitation force according to the vibration acts on the tool 200 installed on the rotating vibrating body 40, thereby increasing the crushing force or excavation force of the arm. In this process, the elastic member of the elastic support part 80 is expanded and contracted in the rotational direction and the reverse rotational direction to increase the excavation and crushing force.

Accordingly, during excavation and crushing of the arm by the excavation device 10 using the vibrating rotating body according to the present invention, the excitation force generated from the vibration generating unit acts in the rotating direction of the vibrating rotating body 40, and the vibration In the reverse rotation direction of the rotating body, the excitation force is applied by the reaction force of the elastic support member, so that the excavating force, that is, the tool mounted on the tool mounting part 41 of the vibrating rotating body 40 formed on the outer peripheral surface of the vibrating rotating body, is applied. The part to be excavated by the can act as a striking force to be struck, thereby increasing the excavation or crushing force.

With this action, the rotary ripper can maximize the work efficiency of tunnel excavation, arm crushing, and face cutting.

On the other hand, in order to crush the tunnel drilling or arm in the horizontal direction using the excavator 10 using the vibrating rotating body, the rotation installed in the heavy equipment while maintaining the connecting rod 100 in a horizontal state as shown in FIG. The connecting rod 100 is rotated using the unit and at the same time, high-pressure air is supplied through the hollow part of the connecting rod 100 and moved forward.

In this way, the arm is crushed or excavated in the horizontal direction by the tool 200 installed in the tool mounting portion of the vibrating rotating body. In this way, in the process of crushing and excavating the arm, the vibration generating unit 50 vibrates the vibration rotating body 40 in the direction opposite to the rotation direction and the rotation direction as described above, and at this time, the vibration regulating unit ( 80), the elastic support member 83 excites the tool in the direction of rotation and the opposite direction while expanding and contracting, so that the crushing force and digging force of the arm can be increased as described above.

In the process of excavation or crushing, the excavated material generated by the tool is discharged by the excavation discharging unit 110 . That is, the high-pressure air supplied through the hollow part of the connecting rod 100 is supplied to the excavation part of the tool through the pneumatic injection nozzle parts 111 installed in the vibrating rotating body 40, and is crushed by the tool. And the excavated excavated excavated riding on the high-pressure air supplied through the pneumatic injection nozzle unit 111 is discharged to the screw blade 101 formed on the outer circumferential surface of the connecting rod 100 through the excavation discharge unit 112, As the connecting rod 100 rotates, it is discharged to the outside by the screw blade 101 .

As shown in FIG. 8 , when the tilting unit is installed on the outer casing and the support frame, the direction can be adjusted in the process of drilling.

As described above, the excavation apparatus using the vibrating rotating body according to the present invention can increase the excavation and crushing force by providing the vibrating rotating body with the vibrating force by the vibration generating unit in the rotational direction and the reverse rotating direction, and tunnel or drilling work In the process of performing the excavation, the excavated material generated during excavation can be discharged to the outside, so that the drilling efficiency can be increased.

Although the present invention has been described with reference to the embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible therefrom.
