Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a vertical hole drilling device, which is used for excavating vertical holes such as foundation work of high-rise structures such as steel towers and tunnel entrances, especially in mountainous areas where work location conditions are poor. It relates to a hole drilling device.

Conventionally, methods for excavating vertical holes include so-called manual excavation and mechanical excavation.

In the above-mentioned manual digging, generally, as shown in Fig. 1, an earth retention support segment a is provided on the side wall surface of the excavated vertical hole, and a bucket rail b is laid on one side of the earth retention support segment a in the direction of the vertical hole. A bucket c is engaged with the rail b, and the scraps that have been crushed and excavated using an air breaker or the like (not shown) are manually loaded onto the bucket c, and the bucket c is raised to discharge the scraps to the outside. However, since this manual digging method has a bucket c placed on one side of the earth retention support segment a, the position of the bucket c at the bottom of the excavation of the vertical hole is fixed, and therefore the worker must move the bucket The disadvantage is that the work efficiency is low because the shear must be carried and loaded one by one.

On the other hand, mechanical excavators include devices illustrated in FIGS. 2 to 4.

That is, the excavation equipment shown in Fig. 2 is a hydraulic excavator main body d with a telescopic rod e and a hydraulic clam cell f (which can be replaced with a breaker), and excavates the ground with the hydraulic clam cell f. At the same time, the excavated shear is discharged to the outside. However, since this drilling equipment uses a telescopic rod e, there is a limit to the depth of vertical hole excavation, and the hydraulic clam cell f and telescopic rod e cannot be operated from the hydraulic excavator body on the ground. Because of this, there are restrictions in terms of visibility. Furthermore, since the excavation reaction force is received by the hydraulic excavator body, there is a risk that the ground around the vertical hole in which the hydraulic excavator body is located may collapse. In particular, the larger the hydraulic excavator body is made to increase the excavation reaction force, the greater the risk of the ground collapsing.

In addition, the excavation equipment shown in Fig. 3 has a bucket rail h and a hydraulic shovel rail i installed in the earth retaining support segment g in the vertical hole direction, and a bucket truck j and a hydraulic shovel main body k are installed on the rails h and i. When engaged with each other, a hydraulic excavator excavates the ground, loads the shear into a bucket j, and raises the bucket j to discharge the shear to the outside.
In the figure, l is a rope for suspending the hydraulic excavator main body k, and m is a cab tire cable for electric power. However, this drilling rig has earth retention support segment g.
Hydraulic excavator body k is attached to rail i laid on one side.
, the excavation reaction force of the hydraulic excavator is applied to one side of the earth retention support segment g via the rail i. Therefore, since a biased load is applied to the earth retention support segment g, there is a risk that the earth retention support segment g, which is strong against uniform earth pressure but weak against localized force, may become loose, deformed, or be damaged. be.

Further, the excavation equipment shown in Fig. 4 consists of an excavation machine o equipped with an excavation part n at the tip, and a dust collector p connected to the excavation machine o, and the excavation machine o and the dust collector p are suspended. The device is suspended by a rope q, and a dust discharge pipe r is connected to a dust collector p. It is discharged to the outside through r. However, this excavation equipment needs to be equipped with an excavator o suitable for the hardest ground, so the excavator o becomes larger and more expensive, and it is difficult to transport the large excavator o in mountainous areas. There is also a problem.

The present invention aims to provide a vertical hole drilling device that improves the above-mentioned drawbacks.

In the present invention, a supporting part is installed around a vertical hole, a cylindrical body is suspended from the supporting part into the vertical hole, and a bucket is inserted into the cylindrical body so as to be movable up and down, and the lower end of the cylinder is vertically attached.

The vertical hole drilling device of the present invention in this embodiment is as follows:
It has the above configuration, and its working process will be explained below.

First, a supporting wall 12 is placed around the location where the vertical hole is to be excavated.
is assembled, pre-excavation is performed within the support wall 12 to such an extent that the support leg 4 does not touch the beam 13, and the earth retaining support segment 18 is assembled to the side wall surface where the pre-excavation has been performed. This earth retaining support segment 18 is an annular segment divided into two or three parts, and is assembled into an annular shape on the side wall surface of the vertical hole.

Next, the support legs 4, rotating part 5, hopper 7, and conveyance part 8 are assembled in the preliminary excavation, and supported by the support legs 4 on the excavation bottom of the preliminary excavation. On the other hand, supporting wall 1
A beam 13 is assembled on the beam 13, and the earth removal section 2 and the lifting/lowering swing section 3 are assembled on the beam 13, and the upper end of the main cylinder 11, whose lower end is integrally attached to the support leg 4, is attached to the beam 13 in a non-rotatable and axial manner. The bucket belt 10 is engaged to be movable in the direction, and the bucket belt 10 is linked to the lifting/lowering swinging unit 3.

Then, do the main digging. That is, in the case of relatively soft ground, excavation is performed manually, and in the case of relatively hard ground, excavation is performed using an air breaker.
In this case, as the legs 46 of the support legs 4 go downward, their cross sections become thinner and follow the side wall surface of the vertical hole, so the working space can be widened, and the loading section 81 of the conveying section 8 can be Since the rotating part 5 rotates along the circular side wall surface of the vertical hole, the distance for the worker to carry the shear to the loading part 81 is shorter compared to the conventional manual digging. Work efficiency can be improved. Further, the reaction force and torsion generated during rotation of the rotating section 5, hopper 7, and conveying section 8 are received by the beam 13 via the support leg 4 and the main cylinder 11, respectively. Therefore, unlike conventional mechanical excavation (as shown in FIGS. 2 and 3), there is no risk of a reaction force building up in a portion of the vertical hole and causing the ground or earth retention support segment to collapse. Note that the legs 44 of the above-mentioned support legs 4
The thin cross-sectional shape of the main cylinder 11 has sufficient strength to withstand reaction force, and the wall thickness of the main cylinder 11 is such that it can sufficiently withstand twisting.

Then, the excavated waste is discharged to the outside via the conveyance section 8, hopper 7, bucket 10, and earth removal section 3. In this case, since the bucket 10 that transports the shear from the lower excavation section to the upper earth removal section is guided by the main cylinder 11, the bucket 10
It is possible to prevent shear from scattering during hoisting.

Then, as the excavation progresses, the support legs 4 are lowered, and the main cylinder 11 is lowered accordingly.
In addition, it is necessary to add a new short pipe, and it is also necessary to add a new earth retaining support segment 18.
That is, the bucket 10 is temporarily placed on the chute 21, a short tube is suspended from the wire rope 34, and the short tube is fixed to the upper end of the main cylinder with a bolt. next,
The chute 21 is reversed, the opening/closing lid 16 is opened, and the earth retaining support segment 18 is suspended from the wire rope 34 and sent into the work space. Note that the earth retaining support segment 18 may be placed on the support leg 4 in advance. The earth retaining support segment 18 is assembled to the side wall surface of the vertical hole. The above operations are repeated to excavate the vertical hole to a predetermined depth.

Once the vertical hole has been excavated to the required depth, the earth removal section 3
is disassembled, and the main cylinder 11 is successively lifted out from above and disassembled. Next, the legs 44, the hopper 7, and the conveyance part 8 are removed from the support leg 4, and the support leg 4 and the rotating part 5 are lifted up and temporarily secured to the lower surface of the beam 13 with bolts, etc., and the legs 6, hopper 7, and The conveying section 8 is lifted up and removed. Then beam 1
3. Disassemble the supporting wall 12, supporting legs 4, and rotating part 5 using another derrick or the like. Note that this device may be sequentially disassembled and removed from the top using another derrick or the like.

In this way, since excavation is carried out within the working space, there is no need to worry about restrictions in terms of visibility as in conventional mechanical excavation (as shown in FIG. 2). Also,
Since excavation is carried out using manual labor or an air breaker, depending on the hardness or softness of the ground, the entire equipment is larger and more expensive than conventional mechanical excavation (as shown in Figure 4), and there are problems with transportation. There is no doubt that there is a problem.

In addition, in the above-mentioned embodiment, the chute 21
Although the chute 21 is of a rotary type and a single winch 35 is used for both hoisting the bucket 10 and carrying in materials, the chute 21 may be of a fixed type. In this case, the swinging distance A of the bucket 10 is made as large as possible, and a winch for carrying in materials is provided separately.

The base end of the arm 62 is attached so as to be rotatable in the vertical direction with a pin 63, and a cutter drum 64 is attached to the tip of the arm 62 at a location _R2 eccentric from the center of rotation of the bracket 61. Said casing 5
A cylinder 65 for horizontal swing is interposed between the arm 61 and the arm 61, and a cylinder 66 for vertical swing is interposed between the bracket 61 and the arm 62, and the cylinder 65 for horizontal swing is operated. By doing so, the cutter drum 64 is moved away from the center of the rotating section 5 via the bracket 61 and the arm 62.
R ₁ Swing horizontally around the swing ring 60 at the eccentric location. On the other hand, by operating the vertical swinging cylinder 66, the cutter drum 64 is swung up and down via the arm 62 around the pin 63 located at a location _R1 eccentric from the center of the rotating section 5. The cutter drum 64 has a main body 640 attached to the arm 62, a drive motor 641 mounted on the main body 640, and a conical disk type drum cutter 6.
42 is rotatably supported diagonally, and its cutter 6
42 and the drive motor 641 are connected to a reducer (not shown).
The above-mentioned power supply cab tire cable 903 on the output side is connected to the drive motor 641. A cover 6 for preventing shearing and scattering is provided on the main body 640.
43 so that one end covers the cutter 642 and the other end is located in the loading section 81 of the conveyance section 8,
Driven sprocket 64 at the other end of the cover 643
A drive sprocket 645 is attached to the cutter 642, and a chain conveyor 646 for shearing is routed between the drive sprocket 645 and the driven sprocket 644 to drive the drive motor 641. According to
The cutter 642 rotates to excavate the ground, and lifts up the excavated waste in the direction of the arrow. Along with the lifting action of the cutter 642, the chain conveyor 646 moves in the direction of the arrow, and the waste is transferred to the loading section 81 of the conveyance section 8. It is configured so that it can be loaded by springing out.

The vertical hole drilling device of the present invention in this embodiment is as follows:
It has the above configuration, and its operation will be explained below.

That is, first, the cutter 642 is positioned on the outer periphery of the excavated bottom of the vertical hole, and the cutter 642 is driven and rotated by the rotating section 5.
After one rotation, raise the cutter 642 and move it inward, then remove the cutter 642.
Lower it and rotate it. Thereafter, the above-mentioned operation is repeated to excavate the entire bottom of the vertical hole. In this case, the ground is excavated by the cutter 642, and the excavated shear is thrown up and automatically loaded into the loading section 81 of the conveying section 8 by the chain conveyor 646, so that the vertical hole excavation according to the above-mentioned first aspect of the present invention is carried out. Work efficiency is better compared to other equipment.

In addition, if the ground is hard, you may use an air breaker together with excavation.

As is clear from the above embodiments, the vertical hole drilling equipment of the present invention is supported by support legs installed at the excavation bottom of the vertical hole and supporting parts installed around the vertical hole through a cylindrical body. Therefore, there is no risk that the area around the vertical hole or the earth retaining support segment will collapse. Furthermore, since the worker works in the space formed by the support legs, there is no restriction in visibility. Furthermore, since the transport section that transports the shear is rotatably attached to the support leg, the transport section rotates at the bottom of the excavation of the vertical hole, and the distance for the worker to transport the shear to the transport section is reduced compared to conventional manual excavation. Since it is extremely small compared to , work efficiency can be improved. In addition, it is possible to use hand digging, air breakers, cutters, etc. depending on the hardness and softness of the ground, so there is no need to make the entire device larger than necessary, the price can be reduced, and the device can be transported. There is no risk of inconvenience when doing so.

Further, in the present invention, by using an excavation section that excavates the ground and picks up the excavated shear, the labor of transporting the shear to the conveyance section can be omitted, and work efficiency can be further improved.
