Technical Field

[0001] The present invention relates to a drilling operation system for drilling an inclined surface such as a mountainous area by operating a drilling device.

Background Art

[0002] Conventionally, a guide post held in an erected state on an inclined surface by a wire, a slide table slidably attached in the longitudinal direction of the guide post, and a drilling machine body detachably attached to the slide table so as to be movable together with the slide table, and a drilling rod extending from the drilling machine body in the longitudinal direction of the guide post.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Incidentally, in the above-described drilling device, the operator a at the foot of the mountain H accurately grasps the installation states of the guide post 3 installed on the inclined surface K and the drilling machine body 2, the progress of the drilling operation, etc., and by operating the lever on the operation panel 50, it is necessary to appropriately supply the compressed air that drives the drilling machine body 2 by operating various switching valves or on-off valves provided in the supply hoses 53 and 54 of the compressed air.

[0006] At this time, if the installation location of the drilling machine body 2 and the standing position of the operator a are far apart, or if the installation location of the drilling machine body 2 is covered by trees or the like, the state of the drilling machine body 2 cannot be accurately visually observed from the foot of the mountain H, and there is a risk that the switching valve or the like cannot be operated at an appropriate timing. For this reason, in addition to the operator a who operates the lever of the operation panel 50 at the foot of the mountain H and the handyman b who performs the installation work of the drilling machine body 2 on the inclined surface K, a monitoring worker c who monitors the progress of the drilling operation and the like is arranged at the drilling work position. Then, the monitoring worker c and the operator a at the foot of the mountain H communicate with each other using a transceiver or a loudspeaker, etc., and while confirming the progress and safety of the drilling operation, the drilling device has to be operated, which requires a large number of workers and has the problem that accurate and rapid drilling work is difficult.

[0007] An object of the present invention is to provide a drilling operation system for an inclined surface that can accurately and quickly perform drilling work by a small number of workers on an inclined surface composed of a mountain slope or the like.

[0008] The present invention includes the following inventions.

The compressed air supply source has a compressed air control unit for controlling the supply of the compressed air according to the operation signal.

[0010] (2) The operation means consists of a wireless communication device that transmits a wireless signal as the operation signal, and the compressed air supply source has a receiver for receiving the wireless signal. The hole-drilling operation system for an inclined surface according to (1).

[0011] (3) It includes a wire for holding the guide post in a state of being erected on the inclined surface, and a wire driving unit for winding and unwinding the wire. The operation means is provided with a compressed air operation unit for instructing the output of the operation signal to the compressed air control unit, and a wire operation unit for instructing the output of the operation signal to the wire driving unit. The hole-drilling operation system for an inclined surface according to (1) or (2).

Advantages of the Invention

[0012] According to the hole-drilling operation system for an inclined surface described in (1), while the operator at the hole-drilling work position on the inclined surface checks the installation state and operating state of the hole-drilling device, by operating the operation means to output an operation signal to the compressed air control unit of the compressed air supply source at the foot of the mountain, the supply of compressed air can be controlled to operate the drilling machine body. Therefore, it is not necessary to arrange an operator who operates the operation panel of the compressed air supply source at the foot of the mountain as in the prior art, and it is possible to quickly and accurately perform the hole-drilling work on the inclined surface with a small number of workers.

[0013] According to the hole-drilling operation system for an inclined surface described in (2), the hole-drilling work can be carried out by operating the compressed air control unit of the compressed air supply source without installing a communication cable or the like for transmitting an operation signal from the operation means to the compressed air supply source on the inclined surface such as in mountainous areas.

[0014] According to the hole drilling operation system for the inclined surface described in (3), an operating worker at the hole drilling operation position on the inclined surface can execute both the control for appropriately supplying compressed air using one operating means and the control for winding and feeding out a wire. Therefore, when the standing angle of the guide post becomes unnatural during the hole drilling operation by the hole drilling device, etc., the operating worker at the hole drilling operation position can appropriately operate the wire driving unit to easily and quickly adjust the standing angle of the guide post.

Embodiments for Carrying Out the Invention

[0016] Hereinafter, embodiments according to the present invention will be described with reference to the drawings. In each figure, components denoted by the same reference numerals are the same components, and their descriptions will be omitted.

[0017] As shown in FIG. 1, a hole drilling operation system 1 for an inclined surface K according to an embodiment of the present invention includes a hole drilling machine body 2 having a hole drilling rod 21, a guide post 3 erected at the hole drilling position of the inclined surface K and slidably supporting the hole drilling machine body 2, a holding mechanism 4 for holding the guide post 3 in an erected state, a compressed air supply source 5 for supplying compressed air for driving the hole drilling machine body 2, and a generator 7 for supplying power to the holding mechanism 4 and the compressed air supply source 5. The hole drilling device further includes an operating means 6 for outputting an operation signal to the hole drilling device.

[0018] The hole drilling machine body 2 includes a drilling rod 21 provided with a drill bit at its tip, a rod drive unit 22 that applies a rotational force and an impact force to the drilling rod 21, and a slide support base 23 that slidably supports the rod drive unit 22. A supply hose 53 for compressed air is connected to the rod drive unit 22, and by supplying compressed air for rotational drive to the rod drive unit 22 via the supply hose 53, the drilling rod 21 is rotationally driven in the forward or reverse direction. Further, by supplying compressed air for impact to the rod drive unit 22 from the compressed air supply source 5 via the supply hose 53, the drilling rod 21 performs a piston motion back and forth to drill the inclined surface K.

[0019] The guide post 3 includes a guide bar 31 that slidably supports the slide support base 23 of the hole drilling machine body 2, and a forward and backward drive unit 32 including a rack and pinion mechanism or the like that slidably displaces the slide support base 23 along the guide bar 31. A supply hose 54 for compressed air is connected to the forward and backward drive unit 32, and by supplying compressed air for forward movement to the forward and backward drive unit 32 via the supply hose 54, the slide support base 23 is driven to gradually move forward along the guide bar 31. Also, when the hole drilling operation by the hole drilling device is completed, by supplying compressed air for backward movement to the forward and backward drive unit 32 from the compressed air supply source 5 via the supply hose 54, the forward and backward drive unit 32 is driven to move backward to the initial position along the guide bar 31.

[0020] The holding mechanism 4 that holds the guide post 3 includes an electric hoist 41 installed at a location above the inclined surface K or the like, an upper wire 42 that is held by the electric hoist 41 so as to be wound up and paid out, a fixing member 43 fixed at a location above the hole drilling operation position, and a lower wire 44 stretched between the fixing member 43 and the lower part of the guide post 3. Then, the upper part of the guide post 3 erected at the hole drilling operation position of the inclined surface K is supported by the upper wire 42, and the lower part of the guide post 3 is supported by the lower wire 44, so that the guide post 3 is held in an erected state.

[0021] The electric hoist 41 is a wire driving unit that winds and pays out the upper wire 42 by rotating the winding drum around which the upper wire 42 is wound in both forward and reverse directions. For example, when the winding drum of the electric hoist 41 rotates forward in response to the power supplied from the generator 7, the upper wire 42 is wound around the winding drum, and the upper end of the guide post 3 is displaced upward. Further, when the winding drum of the electric hoist 41 rotates in reverse, the upper wire 42 is paid out from the winding drum, and the upper end of the guide post 3 is displaced downward.

[0022] The compressed air supply source 5 includes an air tank 51 that stores the air compressed by an air compressor (not shown), and a control panel 52 that controls the compressed air derived from the air tank 51 to be supplied to the rod driving unit 22 of the drilling machine body 2 and the forward and backward driving unit 32 of the guide post 3, respectively. As shown in FIG. 2, the control panel 52 is provided with a compressed air control unit including a first control unit 57 that controls the electromagnetic valve 55 for drilling provided in the supply hose 53, and a second control unit 58 that controls the electromagnetic valve 56 for forward and backward movement provided in the supply hose 54, and a receiver 59 that receives the wireless signal transmitted from the operation means 6.

[0023] The operation means 6 is a wireless communication device including a compressed air operation unit 61 that instructs to output an operation signal to the control panel 52 of the compressed air supply source 5, a wire operation unit 62 that instructs to output an operation signal to the electric hoist 41 of the holding mechanism 4, and a transmitter 63 that transmits a wireless signal to the control panel 52 of the compressed air supply source 5 and the electric hoist 41 of the holding mechanism 4. The compressed air operation unit 61 is provided with a rotation switch 64 that instructs to rotate the drilling rod 21 in the forward or reverse direction, a striking switch 65 that instructs to move the drilling rod 21 in the piston motion forward and backward, and a forward and backward switch 66 that instructs to slide and displace the drilling machine body 2 along the guide bar 31. Further, the wire operation unit 62 is provided with a winding switch 67 that instructs to wind the upper wire 42 of the holding mechanism 4, and an operation switch 68 that instructs to pay out the upper wire 42.

[0024] When performing a drilling operation using the drilling operation system 1 for the inclined surface K according to the present invention, first, as shown in FIG. 3, an air compressor 5 is installed at the foot H of the inclined surface K, and an electric hoist 41 and a generator 7 are installed above the inclined surface K or the like. Next, the operator A and the hand operator B cooperate to set up the drilling machine body 2 and the guide post 3 at the drilling operation position on the inclined surface K. Further, the tip of the upper wire 42 drawn out from the electric hoist 41 is locked to the upper end of the guide post 3, and a lower wire 44 is stretched between the fixing member 43 and the lower part of the guide post 3, so that the drilling machine body 2 and the guide post 3 are held in a state of being erected at a predetermined angle. Furthermore, as shown in FIG. 1, the supply hose 53 of the air compressor 5 is connected to the rod drive unit 22 of the drilling machine body 2, the supply hose 54 of the air compressor 5 is connected to the forward and backward drive unit 32 of the guide post 3, and the conductive wires of the generator 7 are respectively connected to the electric hoist 41 of the holding mechanism 4 and the control panel 52 of the air compressor 5 or the like.

[0025] After installing the drilling device at the work site as described above, the operator A at the drilling operation position on the inclined surface K operates the rotation switch 64 of the operating means 6, and a rotation operation signal for rotating the drilling rod 21 forward or backward is transmitted from the transmitter 63 toward the air compressor 5. Further, when the operator A operates the striking switch 65 of the operating means 6, a striking operation signal for causing the drilling rod 21 to perform a piston motion back and forth is output from the transmitter 63 toward the air compressor 5.

[0026] When the rotation operation signal is received in the control panel 52 of the air compressor 5, the first control unit 57 operates the drilling electromagnetic valve 55, and control for supplying compressed air for rotation operation to the rod drive unit 22 is executed. Also, when the striking operation signal is received in the control panel 52, the first control unit 57 operates the drilling electromagnetic valve 55, and control for supplying compressed air for striking operation to the rod drive unit 22 is executed. As a result, the drilling rod 21 of the drilling machine body 2 rotates forward or backward, and its tip hits the inclined surface K, so that the inclined surface K is drilled.

[0027] Also, as the drilling operation on the inclined surface K progresses, the operator A operates the forward and backward switch 66 of the operating means 6, and transmits a forward operation signal for advancing the slide support base 23 of the drilling machine body 2 from the transmitter 63 toward the compressed air supply source 5. When this forward command signal is received in the control panel 52 of the compressed air supply source 5, the second control unit 58 operates the forward and backward solenoid valve 56, and control is executed to supply compressed air for forward operation to the forward and backward drive unit 32. As a result, the slide support base 23 of the drilling machine body 2 advances along the guide bar 31, and the tip of the drilling rod 21 enters the ground.

[0028] Then, when it is confirmed that the inclined surface K has been drilled to a predetermined depth and the drilling operation has ended, the operator A operates the forward and backward switch 66 of the operating means 6, and transmits a backward operation signal for retracting the slide support base 23 of the drilling machine body 2 from the transmitter 63 toward the compressed air supply source 5. When the backward operation signal is received in the control panel 52 of the compressed air supply source 5, the second control unit 58 operates the forward and backward solenoid valve 56, and control is executed to supply compressed air for backward operation to the forward and backward drive unit 32. As a result, the slide support base 23 of the drilling machine body 2 retracts to the initial position along the guide bar 31, and the drilling machine body 2 and the guide post 3 are in a state where they can be moved to a new drilling operation position.

[0029] As described above, the drilling operation system 1 for the inclined surface K according to the present invention is provided with a compressed air control unit including a first control unit 57 and a second control unit 58 in the compressed air supply source 5 of the drilling device, and is configured to supply compressed air to the drive unit of the drilling machine body 2 by operating it according to the operation signal output from the operating means 6. Therefore, it has a unique effect that the drilling device can be appropriately operated by a small number of workers to properly execute the drilling operation on the inclined surface K.

[0030] That is, while the operator A at the drilling operation position checks the progress of the drilling operation and the like, the operator operates the operating means 6 to output an operation signal to the control panel 52 of the compressed air supply source 5, and appropriately operates the compressed air control unit composed of the drilling electromagnetic valve 55 and the forward and backward electromagnetic valve 56 provided in the supply hoses 53 and 54 of the compressed air, whereby the drilling machine main body 2 of the drilling device can be properly driven to drill the inclined surface K. Therefore, unlike the conventional example shown in FIG. 4, it is not necessary to arrange the operator a at the foot of the mountain H, which has the advantages of reducing the number of workers and enabling the drilling operation of the inclined surface K to be executed quickly and accurately.

[0031] In addition, instead of the operating means 6 composed of a wireless communication device that transmits a wireless signal to the compressed air supply source 5, it is also possible to use a remote control type operating means that transmits a wired signal to the compressed air supply source 5. In this case, however, it is necessary to install a communication cable for signal transmission on the inclined surface K such as a mountainous area. On the other hand, when a wireless signal is transmitted by the operating means 6 composed of a wireless transmitter as shown in the above-described embodiment and a receiver 59 that receives the wireless signal is provided in the compressed air supply source 5, there is an advantage that the supply control of the compressed air can be executed without installing a communication cable for signal transmission.

[0032] Also, when configured such that the wire operation unit 62 that outputs an operation command signal to the electric hoist 41 that winds and unwinds the upper wire 42 that holds the guide post 3 is provided in the operating means 6 as shown in the above-described embodiment, the operator A at the drilling operation position on the inclined surface K can use one operating means 6 to execute both the supply control of the compressed air as described above and the angle adjustment control of the guide post 3 as described below.

[0033] For example, when the standing angle of the guide post 3 becomes unnatural during the hole drilling operation by the hole drilling device or the like, in order to adjust this to an appropriate angle, the operator A at the hole drilling operation position can use the operating means 6 to operate the electric hoist 41 without moving to the installation part of the electric hoist 41, and by winding in or paying out the upper wire 42, the standing angle of the guide post 3 can be adjusted easily and quickly.
