Description

  The present invention relates to a drilling work vehicle such as a crawler drill.

For example, in mining and quarrying workplaces, drilling a blast hole of a predetermined depth in the rock, and then exploding with an explosive in the blast hole, crushing the rock and collecting ore, Blasting work is done to remove unnecessary bedrock. For example, a crawler drill is used as a work vehicle used for the drilling holes at this time.
This type of crawler drill includes a traveling carriage 104 in which a traveling crawler device 2 is provided at a lower portion of a frame 3, as in a crawler drill 100 illustrated in FIG. 6. A cabin 105 which is a cockpit is fixed on the traveling carriage 104. A boom device 6 is provided on the front side of the traveling carriage 104. And the guide shell 8 etc. are supported by the front-end | tip part of this boom apparatus 6 as an operation | work apparatus for performing required drilling work.

  When the blasting operation is performed by the crawler drill 100, the crawler device 2 is self-propelled to a position necessary for the drill hole, and the guide shell 8 is positioned at a predetermined drill hole position of the rock GL. Then, the guide shell 8 on which the predetermined bit 10 is mounted is positioned at a predetermined drilling position of the rock GL, and is positioned in a necessary posture for the drilling hole. Then, hitting, rotating and feeding are applied to the bit 10 at the tip of the rod 9 to drill a blast hole in the rock. When the drilling operation is completed, an explosive is inserted into the blasting hole, which is then exploded to crush the bedrock. Here, the operation for drilling is performed from the cabin 105 on the traveling carriage 104 by the operator.

  However, in such a conventional crawler drill, since the cockpit (cabin) is fixed on the traveling carriage, the position of the guide shell positioned at a position corresponding to a predetermined drill hole position is separated. Therefore, it may be difficult for an operator in the cockpit to visually recognize a part necessary for performing a confirmation work necessary for the drilling hole, such as a screw joining / cutting work. Therefore, conventionally, in such a case, there has been a problem that the operator has moved away from the cockpit to a position where it can be easily seen, and the confirmation work has been performed, and the work efficiency has been poor.

Therefore, for example, in the technique described in Patent Document 1, a slide movement mechanism that slides the cockpit along the front and rear directions of the traveling carriage is provided, and thereby a guide shell that is positioned at a position corresponding to a predetermined drill hole position is provided. On the other hand, the visibility of the operator is improved, the necessary confirmation work is facilitated, and the work efficiency can be improved.
Japanese Utility Model Publication No. 56-175220

However, in the technique described in Patent Document 1, since the cockpit is merely slid along the traveling carriage longitudinal direction, the height of the entire cockpit remains the same as the initial height on the traveling carriage. is there. Therefore, as a necessary work for drilling holes, for example, it is suitable for securing the field of view at the time of screw splicing / cutting, but for example, in the work of checking the bit position when drilling, a bit is located below the cockpit. Since it is located, the visibility is not good. The field of view at the time of drilling is maintained by attaching an inclined guide mounting or a guide rotary, but it is insufficient for improving the visibility. Further, since the height of the entire cockpit remains the same as the height on the traveling carriage, when the operator gets into the cockpit, as shown in FIG. 6, a ladder 107 attached to the cockpit, etc. There is still a problem to be solved in this respect.
Therefore, the present invention has been made paying attention to such problems, and improves all of the visibility of the screw splicing / cutting operation, the visibility of the bit position, and the ease of entering the cockpit. An object of the present invention is to provide a drilling work vehicle and a drilling method using the drilling work vehicle.

  In order to solve the above-described problems, the present invention provides a traveling carriage, a working device that is mounted on the traveling carriage and performs a necessary work in a drill hole, a cockpit attached to the traveling carriage and having a cockpit, A drilling hole working vehicle including a cockpit moving mechanism for positioning the cockpit in a traveling position and a work position for performing work necessary for the drilling hole, wherein the cockpit moving mechanism includes the traveling carriage. A slide movement mechanism provided on the slide for moving the cockpit in the longitudinal direction of the vehicle body, and a rotational movement connected to the slide movement mechanism on the front side of the traveling carriage to raise and lower the cockpit with respect to the carriage A first position in which the cockpit is slid toward the traveling carriage, and the cockpit is separated from the traveling carriage and slid forward in the traveling carriage. And the rotational movement mechanism is configured to position the cockpit to be moved up and down at a second work position that is lower than the first work position. It is a feature.

  According to the drilling work vehicle according to the present invention, the cockpit moving mechanism is provided. The cockpit moving mechanism has a slide moving mechanism, and the slide moving mechanism slides the cockpit closer to the traveling carriage. Since it is designed to be located at the travel position moved and the first work position where the cockpit is slid away from the travel cart and moved forward in the travel cart, As in the prior art, the operator can travel from the cockpit on the traveling carriage to the position required for the drill hole. If the cockpit is set as the first work position, the cockpit is slid forward from the traveling carriage away from the traveling carriage, so that, for example, a field of view at the time of screw joining / cutting work can be secured.

  Further, the cockpit moving mechanism has a turning movement mechanism, and the turning movement mechanism has a second height that is lower than the first working position with respect to the cockpit that is moved up and down. Therefore, even when the bit is positioned below, the field of view at the time of checking the bit position can be secured. Since the second work position is lower than the first work position, it is possible to directly enter the cockpit without adding a ladder or the like to the cockpit, for example. That is, the boarding ability to the cockpit is also improved. Therefore, according to the drilling work vehicle according to the first aspect of the present invention, it is possible to improve all of the visibility of the screw splicing / cutting operation, the visibility of the bit position, and the ease of getting into the cockpit.

  Here, in the drilling work vehicle according to the present invention, the cockpit moving mechanism includes a balance weight that slides along the front-rear direction of the traveling carriage at the rear of the traveling carriage. In conjunction with the slide moving mechanism, when the slide moving mechanism slides the cockpit forward to the traveling carriage, the slide movement mechanism slides backward to the traveling carriage, and the slide moving mechanism slides the cockpit backward to the traveling carriage. When it is made to move, it is preferable that it is made to slide to the front of the traveling carriage.

  Such a configuration is suitable for stabilizing the posture of the drilling work vehicle because it can prevent or suppress a change in the center of gravity when the cockpit moving mechanism is operated. In other words, when the cockpit is slid in the longitudinal direction of the traveling carriage with the slide movement mechanism, the center of gravity of the entire drilling work vehicle also moves in the longitudinal direction of the traveling carriage as the slide moves, but this balance weight is applied to the sliding movement mechanism. Since it moves in the direction opposite to the longitudinal direction of the traveling carriage, the posture of the drilling work vehicle can be stabilized.

  Further, in the drilling work vehicle according to the present invention, the traveling carriage is provided with a hydraulic pump and an engine behind the cockpit, and the cockpit moving mechanism moves the cockpit to the first work. It is preferable that a utility space capable of maintaining the hydraulic pump and the engine appears when the position or the second working position is set. With such a configuration, if the cockpit is set to the first work position or the second work position, a utility space capable of maintaining the hydraulic pump and the engine will appear, so that the maintainability can be further improved. Can do.

  As described above, according to the present invention, it is possible to provide a drilling work vehicle that can improve the visibility of screw splicing / cutting work, the visibility of the bit position, and the ease of getting into the cockpit. it can.

Hereinafter, an embodiment of a drilling work vehicle according to the present invention will be described with reference to the drawings as appropriate. FIG. 1 is a view for explaining a crawler drill which is an embodiment of a drilling work vehicle according to the present invention. FIG. 1 (a) is a plan view, FIG. 1 (b) is a side view, and FIG. FIG. In addition, about the structure similar to the said conventional crawler drill, the same code | symbol is attached | subjected and demonstrated.
As shown in FIG. 1, the crawler drill 1 includes a traveling carriage 4 in which a traveling crawler device 2 is provided at a lower portion of a frame 3. The traveling carriage 4 is provided with a cabin 5, which is a cockpit having a cockpit, and a boom device 6 on the front side of the traveling carriage 4. A guide shell 8 on which a drifter 7 is mounted is supported at the tip of the boom device 6 as a working device for performing necessary drilling work. Note that a hydraulic pump and an engine are arranged on the traveling carriage 4 immediately behind the cabin 5 (see FIG. 5 described later).

The boom device 6 has driving means for positioning the guide shell 8 in a posture necessary for drilling, and a bit 10 is attached to the tip of the drifter 7 mounted on the guide shell 8. A rod 9 is attached. Thereby, this crawler drill 1 can be drilled at a desired position in the rock by giving impact, rotation and feed to the bit 10 at the tip of the rod 9.
Here, the crawler drill 1 further includes a cabin moving mechanism (cockpit moving mechanism) 20 that positions the cabin 5 at each of the travel positions and work positions for performing work necessary for the drill holes. The cabin movement mechanism 20 includes a slide movement mechanism 22 and a rotation movement mechanism 24.

  Specifically, as shown in FIG. 2, the slide moving mechanism 22 includes a slide guide rail 22 a and a hydraulic cylinder 22 b disposed along the front-rear direction of the traveling carriage 4. The slide guide rail 22a includes a base portion fixed to the frame 3, and a movable portion that slides and moves to the front side in the front-rear direction of the traveling carriage 4 with respect to the base portion. The hydraulic cylinder 22b has two rods, a first rod 22c facing forward in the front-rear direction of the traveling carriage 4 and a second rod 22d facing backward.

  The first rod 22c of the hydraulic cylinder 22b is connected to the movable part of the slide guide rail 22a via a support shaft. Thereby, the movable part of the slide guide rail 22a is slid in accordance with the expansion and contraction of the first rod 22c of the hydraulic cylinder 22b. When the first rod 22c is shortened the most, the cabin 5 is positioned at the traveling position (position shown in FIG. 1) slid toward the traveling carriage 4, and when the first rod 22c is extended the most, the cabin 5 is positioned at a first work position (position shown in FIG. 4 later) which is slid away from the traveling carriage 4 and moved forward.

  Further, the cabin moving mechanism 20 includes a balance weight 26 that slides along the front-rear direction of the traveling carriage 4 behind the traveling carriage 4. As shown in FIG. 2, the balance weight 26 is placed on a guide device 27 provided on the frame 3, and is supported by the guide device 27 so as to be slidable along the front-rear direction of the traveling carriage 4. ing. Further, the balance weight 26 is connected to the tip of the rearward second rod 22d of the hydraulic cylinder 22b via a support shaft.

  Here, the second rod 22d of the hydraulic cylinder 22b expands and contracts in conjunction with the expansion and contraction of the first rod 22c opposite to the hydraulic cylinder 22b, whereby the balance weight 26 is moved to the slide moving mechanism 22. In conjunction with this, when the slide moving mechanism 22 slides the cabin 5 to the front of the traveling carriage 4, the sliding movement mechanism 22 slides to the rear of the traveling carriage 4, and the slide moving mechanism 22 slides the cabin 5 to the rear of the traveling carriage 4. Sometimes, it is slid to the front of the traveling carriage 4.

  On the other hand, the rotational movement mechanism 24 is connected to the slide movement mechanism 22 on the front side of the cabin 5 so as to raise and lower the cabin 5 with respect to the traveling carriage 4, thereby moving the cabin 5 raised and lowered from the first working position. It is positioned at the second work position (position shown in FIG. 2), which is the lowered height. Specifically, the rotational movement mechanism 24 has a base end portion 24a rotatably connected to a distal end of the movable portion of the slide guide rail 22a, and a distal end portion 24b of the cabin 5 on the traveling carriage 4 side. Is pivotably connected to the lower part of the surface facing. Here, a pair of rotation mechanisms having a servo motor and a speed reduction mechanism (not shown) are built in the proximal end portion 24a and the distal end portion 24b of the rotation moving mechanism 24. The entire cabin 5 can be moved up and down while maintaining the horizontal posture of the cabin 5 by a pair of rotation mechanisms in the distal end portion 24b.

Next, the action and effect of the crawler drill 1 and the blasting operation (drilling operation) using the crawler drill 1 will be described.
When performing the blasting operation with the crawler drill 1, first, as shown in FIG. 1, the cabin 5 is positioned at the traveling position R, and the crawler device 2 self-travels to a position necessary for the drilling hole. Here, the crawler drill 1 includes a cabin moving mechanism 20, and the cabin moving mechanism 20 includes a slide moving mechanism 22. The slide movement mechanism 22 is positioned at a travel position where the cabin 5 is slid toward the traveling carriage 4 and a first work position where the cabin 5 is moved away from the traveling carriage 4 and slid forward. As shown in FIG. 1, the cabin 5 is set to the traveling position R, and the operator S can self-travel from the cabin 5 on the traveling carriage 4 to a position required for the hole as shown in FIG. it can.

  Next, as shown in FIG. 3, the guide shell 8 on which the predetermined bit 10 is mounted is positioned at a predetermined drilling position of the rock GL, and is positioned in a posture required for the drilling hole. Then, hitting, rotating and feeding are applied to the bit 10 at the tip of the rod 9 to drill a blast hole in the rock. When the drilling operation is completed, an explosive is inserted into the blasting hole, which is then exploded to crush the bedrock.

  Here, for the drilling operation, the operator S rotates the chair 90 degrees in the cabin 5 on the traveling carriage 4, and performs an operation laterally with respect to the traveling direction of the traveling carriage 4. Then, when performing the screw joining / cutting operation, as shown in FIG. 4, the cabin 5 is slid and moved forward from the traveling carriage 4 by the slide moving mechanism 22 to move the cabin 5 to the first operation. Position at position H. As described above, when the cabin 5 is set to the first work position H, for example, it is possible to ensure a good field of view at the time of screw joining / cutting work.

  Further, the cabin moving mechanism 20 has a rotation moving mechanism 24, and the rotation moving mechanism 24 has a height lower than the first working position H of the cabin 5 that is moved up and down by this. Since the bit position confirmation operation is performed at the second work position L, as shown in FIG. 3, the cabin 5 is separated from the traveling carriage 4 by the slide moving mechanism 22, as shown in FIG. 4 It is possible to place the cabin 5 in the second working position L by sliding it forward and lowering it to a lower position by the rotational movement mechanism 24. As a result, a good field of view can be secured even in the bit position confirmation operation. Since the second work position L is lower than the first work position H, the boarding property to the cabin 5 is improved as shown in FIG.

  Further, as shown in FIG. 2, the cabin moving mechanism 20 includes a balance weight 26 that slides along the front-rear direction of the traveling carriage 4 behind the traveling carriage 4. In conjunction with the moving mechanism 22, when the slide moving mechanism 22 slides the cabin 5 forward of the traveling carriage 4, the sliding movement mechanism 22 slides behind the traveling carriage 4, and the slide moving mechanism 22 slides the cabin 5 backwards of the traveling carriage 4. When the vehicle is moved, it is slid in front of the traveling carriage 4, so that it is possible to prevent or suppress a change in the center of gravity when the cabin moving mechanism 20 is operated. Therefore, the posture of the crawler drill 1 can be stabilized.

That is, when the cabin 5 is slid in the longitudinal direction of the traveling carriage 4 by the slide moving mechanism 22, the center of gravity of the entire crawler drill 1 is also moved in the longitudinal direction of the traveling carriage 4 as it slides. This is because the posture of the crawler drill 1 can be stabilized because it moves in the direction opposite to the longitudinal direction of the traveling carriage 4 in conjunction with the mechanism 22.
Furthermore, in the conventional crawler drill illustrated in FIG. 6, when performing maintenance of the engine, the valve, etc., the maintenance is usually performed from a maintenance opening / closing door provided on the traveling carriage 104. In many cases, the maintenance work from the hatch on the side of the carriage as in the prior art is poor in workability.

  On the other hand, in the crawler drill 1, as shown in FIG. 5, a hydraulic pump 31 and an engine 32 are arranged behind the cabin 5, and the cabin moving mechanism 20 moves the cabin 5 to the first working position H or When the second work position L is set (FIG. 5 shows the state of the second work position L), a utility space U in which the hydraulic pump 31 and the engine 32 can be maintained appears. Therefore, if the cabin 5 is set to the first work position H or the second work position L, a utility space U capable of maintenance appears for maintenance equipment such as the hydraulic pump 31 and the engine 32, so that the operator S Maintenance can be performed from this utility space U. Therefore, in this crawler drill 1, approach to the maintenance equipment from the utility space U is easy, and the workability of maintenance is further improved.

As described above, according to the crawler drill 1, it is possible to improve all of the visibility of the screw splicing / cutting operation, the visibility of the bit position, and the ability to enter the cabin 5.
In addition, this crawler drill 1 which concerns on this invention is not limited to the said embodiment, A various deformation | transformation is possible unless it deviates from the meaning of this invention.
For example, in the above-described embodiment, the crawler drill has been described as an example of the drilling work vehicle according to the present invention. However, the crawler drill is not limited thereto. For example, as the drilling work vehicle according to the present invention, It can be applied as long as it has a traveling carriage, a working device that is equipped on the traveling carriage and performs a necessary work in the drill hole, and a cockpit attached to the traveling carriage, for example, a downzer hole drill, The present invention can also be applied to a rotary drill.

  Further, for example, in the above-described embodiment, the cabin moving mechanism 20 has been described as an example including the balance weight 26 that slides along the front-rear direction of the traveling carriage 4 behind the traveling carriage 4, but is not limited thereto. The cockpit moving mechanism of the drilling work vehicle according to the present invention can be configured so as not to have a balance weight if the weight of the traveling carriage is necessary and sufficient to move the center of gravity due to the movement of the cockpit. However, in order to stabilize the posture of the drilling work vehicle more reliably when the cockpit moving mechanism is operated, it is preferable to have a balance weight that is linked to the slide moving mechanism as in the above embodiment.

  Further, for example, in the above-described embodiment, the rotational movement mechanism 24 moves the cabin 5 to the traveling carriage 4 from the first work position to the second work position that is lower than the first work position. However, the present invention is not limited to this, and for example, it may be configured to be capable of rotating upward from the first work position. If the rotational movement mechanism is configured to be able to rotate upward, it can be operated while visually observing the entire area of the guide shell, and it is also preferable for easy maintenance.
