Description

Titanic PRD drilling apparatus and method for performing drilling using the same

The present invention relates to a Titanic PRD drilling apparatus and a method for performing drilling using the same, and more particularly, to a Titanic PRD drilling apparatus capable of performing a drilling operation with low noise and high efficiency while preventing damage to a striking member, and a drilling method using the same .

The drilling operation is an operation that must be preceded in order to construct a structure such as a building. In addition, in order to bury roads, power lines, etc. underground as part of urban planning, drilling work must be preceded to secure a space underground.

Usually, the drilling operation is performed in a vertical direction from the ground surface toward the basement. When the drilling operation is performed to the planned depth, it is common to insert a structure or the like into the drilling to complete the intended operation.

One of the methods for drilling the ground is the PRD method. The PRD method is a buried pile method, and is mainly used when there is a layer of gravel in the ground. Specifically, by rotating a drill bit provided on the lower side, and the like, drilling is performed by the pressing force and the rotational force of the drill bit in the direction from the upper side to the lower side.

When the drilling operation is performed from the ground to the underground, in the initial process, since the drilling operation is performed to a shallow depth underground, a major problem does not occur.

However, as the drilling operation proceeds, when the depth of the point to be additionally drilled increases, excessive equipment and power for driving the same are required in order to continue the drilling operation from the ground surface.

Therefore, in order to effectively perform the drilling operation, it is preferable that the drilling operation is performed underground after the drilling operation is performed by a predetermined depth from the ground surface.

However, when the work is performed underground, the space is generally narrow compared to the case where the work is performed on the ground surface. Therefore, it is difficult to accommodate the existing excavator or excavator having a large volume in the underground space.

Korean Patent Document No. 10-1195476 discloses a rock drill device for a tilting and rotatable excavator. Specifically, the present invention discloses a rock drill device for an excavator having a structure capable of securing a wide working radius and changing a posture by improving a mounting structure of a swing device for rotation of a rock drill body.

However, this type of rock drilling device for an excavator is premised on being used by being added-on to an excavator having a specific structure. That is, when the existing excavator has a structure in which the corresponding rock drill device is difficult to be attached, it is difficult to attach the rock drill device for an excavator according to the prior document.

In addition, in order to operate the rock drill device for an excavator disclosed in the prior document, a separate power must be supplied. Accordingly, there is a limitation in that the overall structure and wiring structure of the excavator are complicated, and it is difficult to reduce the size of the excavator.

Korean Patent Document No. 10-1630089 discloses a percussion drill device using an excavator. Specifically, it discloses a percussion drill device comprising a percussion driving unit for providing a striking force to the plurality of drill bits by hitting one side of the rotary drill part having a plurality of drill bits in the crushing operation.

By the way, it is premised that this type of percussion drill apparatus is also used as an add-on to an excavator having a specific structure. Therefore, there is a limit in that it is difficult to apply depending on the structure of the excavator.

In addition, the percussion drill apparatus disclosed in the prior document is configured to provide a percussion force directly to a plurality of drill bits. Accordingly, it is difficult to exclude not only a separate power source for forming the striking force is required, but also the possibility that a plurality of drill bits may be damaged by the applied striking force.

Furthermore, it is premised that the devices disclosed in the prior documents are provided for an excavator of a size that is difficult to be driven in a small space. Therefore, when the excavation work is to be carried out in a space such as underground rather than on the ground surface, it is difficult to apply the devices disclosed in the prior documents.

According to an embodiment of the present invention, the following effects can be achieved.

First, the Titanic PRD perforation device includes a movable cart portion and a perforation portion removably coupled through the cart portion. The cart unit is manufactured in a small size and can be moved while being accommodated in a narrow underground space.

The Titanic PRD drilling device for substantially performing the drilling operation is lowered from the ground surface and coupled to the cart portion through a passage communicating the ground with the space in which the cart portion is accommodated. That is, since only the cart part of the Titanic PRD drilling apparatus is accommodated in the underground space, the underground space occupied by the Titanic PRD drilling apparatus can be minimized.

Therefore, even in a narrow space, the Titanic PRD drilling apparatus can perform the drilling operation on the target point. Accordingly, the efficiency of the drilling operation may be improved, and the degree of freedom in performing the operation may be improved.

In addition, the cart is rotatably provided, and a rotary table for gripping the perforated pipe is provided. The rotary table is coupled to a lifting member provided in the cart unit, and may be raised and lowered as the lifting member is adjusted. At this time, the perforated pipe gripped by the rotary table may also be raised and lowered together with the rotary table.

The lifting member may be operated according to a control signal input through the control unit. Accordingly, the operator can raise and lower the rotary table and the perforated pipe and perforating member gripped therein by inputting a control signal for a desired height.

Further, in one embodiment, the perforated pipe is provided with a guide projection. The guide protrusion may be maintained in a state of being seated on a seating protrusion formed on the rotary table. Accordingly, the relative distance between the perforated pipe and the ground can be kept constant.

When the rotary table is rotated, the guide protrusion may be lifted apart from the seating protrusion. Accordingly, when a deeper drilling operation is to be performed, the drilling pipe may be moved downward to continue the drilling operation.

The perforation member coupled to the lower side of the perforation pipe is rotated and provided with a striking member for perforating the ground by striking the ground. The striking member may reciprocate in a direction toward the ground and in a direction opposite thereto to perform a drilling operation on the ground.

A plurality of guide protrusions may be provided to be spaced apart from each other. In this case, the distance between the adjacent guide protrusions is formed to be less than the distance at which the striking member reciprocates.

Thus, in this embodiment, the perforated pipe can be lowered by the distance between the guide projections adjacent to each other. Consequently, when the striking member is positioned in a direction opposite to the ground, the striking member is positioned apart from the ground. That is, while the perforated pipe is lowered, the striking member does not contact the ground.

Therefore, in the above embodiment, even if the perforated pipe is raised and lowered, the striking member is not damaged by the ground.

Also, in another embodiment, the perforated pipe may be gripped by a rotary table. When the rotary table is raised by the lifting member, the gripped perforated pipe can also be raised and lowered together. When the rotary table is operated, the gripped perforation pipe is released and lowered so that the striking member can strike and perforate the ground.

Therefore, in the above embodiment, even when the perforated pipe is raised and lowered, a situation in which the striking member is inadvertently in contact with the ground and is damaged can be prevented.

Also, in one embodiment, as the rotary table is rotated, the perforated pipe may be lowered to a desired height. For example, the perforated pipe may be lowered by the distance between the guide projections adjacent to each other. That is, a separate device is not required to precisely control the descending distance of the perforated pipe.

Also, in another embodiment, when the rotary table releases the perforated pipe, the perforated pipe may be lowered by self-weight. That is, a separate power for lowering the perforated pipe is not required.

Accordingly, the power required for the drilling operation to be performed can be minimized. Accordingly, the cost of the operation can be reduced.

In addition, the cart unit is provided with a support member and a moving member. The moving member is configured to be able to move forward, backward, or rotate, so that the cart unit can be precisely moved to a desired point. In one embodiment, the moving member is provided in the form of a caterpillar provided in a caterpillar vehicle, so that it can be stably moved on an uneven surface of the ground.

When the cart portion has reached the desired point, the support member is extended towards the ground. A plurality of support members may be provided, and the cart unit may be supported by the support members at a plurality of points.

Therefore, the Titanic PRD drilling device can be accurately moved to the point where the drilling operation is to be performed, and can be stably fixed at the reached point. Accordingly, the drilling operation can be performed accurately and stably.

Next, the striking ground is depressed and the striking members 540 and 740 moved toward the ground are positioned adjacent to the ground (S420). That is, in this step, the subsidence of the ground proceeds as the drilling operation proceeds, and even if the striking members 540 and 740 are extended to the maximum, an additional blow is not applied to the ground.

When the above step is reached, the drilling operation for the ground cannot proceed at the current height of the drilling part 20 . Accordingly, the perforation 20 should proceed toward the ground (ie, the surface of the recessed ground).

(5) Description of the step (S500) in which the perforation 20 is moved toward the ground

It is a step (S500) in which the perforation 20 is moved toward the surface of the ground to continue the perforation operation. Hereinafter, this step will be described in detail with reference to FIG. 26 .

In this step (S500), a case in which the perforation part 20 according to an embodiment of the present invention is provided and a case in which the perforation part 20 according to another embodiment of the present invention is provided will be described separately.

First, a case in which the perforation portion 20 (ie, including the perforation pipe 400 and the perforation member 500 ) according to an embodiment of the present invention is provided will first be described.

In this case, the perforated portion 20 is rotated relative to the cart portion 10 and moved toward the ground (S510).

Specifically, the perforated pipe 400 of the perforated portion 20 is rotated relative to the support plate 320 of the cart unit 10, and the state in which the guide beam 450 is seated in the seating protrusion 323 is released. becomes (S511).

In this case, the relative rotation may be achieved by rotating the support plate 320 by the gear member 350 .

Specifically, while the support plate 320 is rotated clockwise based on the embodiment shown in FIG. 9 and the drilling operation is in progress, the guide beam 450 is biased to the left with respect to the center of the through hole 321 . It is accommodated in the elevating groove 322 in a state. Accordingly, the guide protrusion 452 is maintained in a state seated on the seating protrusion 323 , and the perforation portion 20 is not arbitrarily raised and lowered.

When the perforation part 20 is to be lifted, the support plate 320 is rotated counterclockwise by the rotation motor 330 and the gear member 350 . Accordingly, the guide extension portion 451 is located adjacent to the edge surrounding the elevating groove 322 on the right side with respect to the center of the through hole 321 . At the same time, the guide protrusion 452 is moved opposite to the seating protrusion 323 so as not to overlap the seating protrusion 323 in the vertical direction. That is, the guide protrusion 452 is released from the support plate 320 .

Next, the perforation 20 is moved toward the ground (S512). This step (S512) will be described in detail as follows.

As described above, the upper end of the perforation 20 is supported by an external crane or the like. When the external crane is operated, the perforation 20 is lowered toward the ground. Accordingly, the height of the guide protrusion 452 (new guide protrusion 452) positioned above the guide protrusion 452 (the previous guide protrusion 452) that was previously seated on the seating protrusion 323 and the seating protrusion 323 ) can be adjusted.

As another example, the rotary table 300 is moved upward by the elevating member 120, and the guide protrusion 452 (previously guide protrusion 452), which was previously seated on the seating protrusion 323, is positioned above the guide protrusion ( The height of the 452 (new guide protrusion 452) and the height of the seating protrusion 323 may be matched.

Next, the perforated portion 20 is rotated relative to the cart portion 10, so that the guide protrusion 452 of the guide beam 450 is seated on the seating protrusion 323 of the cart portion 10 (S513) . This step (S513) will be described in detail as follows.

The support plate 320 is rotated clockwise by the rotation motor 330 and the gear member 350 , and the seating protrusion 323 is moved to the lower side of the new guide protrusion 452 . Accordingly, the new guide protrusion 452 is seated on the seating protrusion 323 .

At this time, the first length (L1) is formed to be less than the second length (L2), even when the perforation 20 is moved downward, the striking member 540 in an unextended state does not come into contact with the ground.

On the other hand, in the other example described above, when the rotary table 300 is moved downward by the elevating member 120, the striking member 540 is separated by the distance between the previous guide protrusion 452 and the new guide protrusion 452. can be moved downwards.

Thereafter, the step ( S400 ) in which the drilling operation is performed by the drilling part 20 is performed, and the drilling operation may be continued.

Next, a case in which the perforation portion 20 (ie, including the perforation pipe 600 and the perforation member 700 ) according to another embodiment of the present invention is provided will be described.

In this step, the perforation 20 is moved downward toward the ground by its own weight (S520).

First, the rotary table 300 rotatably provided in the perforation portion 20 releases the perforation portion 20 (S521). Since the guide protrusion 452 to be seated on the seating protrusion 323 is not provided in the perforation portion 20 according to the present embodiment, a separate holding member (not shown) provided in the rotary table 300 is provided in the perforation portion 20 . ) will be understood.

Next, the perforation 20 released from the rotary table 300 is lowered by its own weight and moved toward the ground (S522). This process is achieved by the weight of the perforation (20).

Next, to be rotated together with the rotary table 300, the perforation 20 is coupled with the rotary table 300 again (S523). Accordingly. The perforation 20 is rotated together with the support plate 320 and the perforation operation may be continued.
