Hereinafter will be described in detail with reference to the accompanying drawings, the most preferred embodiment of the present invention. However, in describing the present invention, when the technical idea of the present invention is obscured or obscured by specifically explaining the known configuration, the description of the above known configuration will be omitted.

Figure 2 is a perspective view showing a rotating rock crushing apparatus 100 according to an embodiment of the present invention, Figure 3 is a cross-sectional view showing a state in which the crushing operation using the rotating rock crushing apparatus 100, 4 is a cross-sectional view showing the rotating rock crushing device 100.

The rotating rock crushing apparatus 100 of the present invention, as shown in Figures 2 and 4, the central body 110 is provided with a central tip 111 at the tip, and the rotating body 120 is installed behind the central body 110 ), A fixed body 130 installed at the rear of the rotating body 120, a supporting body 140 rotating through the rotating body 120, and a perforated portion installed on one side of the supporting body 140 160, and the support 140, the crushing portion 170 is installed on the other side is configured to be included.

The rotating rock crushing apparatus 100 of the present invention configured as described above is installed on heavy equipment such as a backhoe, as referred to in FIG. 3 (in this specification, collectively referred to as 'backhoe'), the central peak of the center body 110 ( 111) is advanced and fixed to the rock surface, and the support 140 is subsequently advanced so that the tip is fixed to the rock surface, and the perforated portion 160 is advanced to form a perforated hole h.

Then, the perforated portion 160 and the support 140 are reversed to return to their original position, and then the rotating body 120 is rotated using the fixing body 130. Then, the crushing part 170 is accurately positioned at the position where the punching part 160 was located, and then the supporter 140 is advanced again and fixed to the rock surface, so that the crushing device 171 is punched hole (h) It is inserted into the crushed rock.

Therefore, the present invention can accurately perform continuous drilling and rock crushing operations with only one device, thereby increasing construction efficiency and significantly reducing construction period.

At this time, the perforated portion 160 and the crushing portion 170 are installed at opposite positions with the same distance based on the central body 110. That is, the perforations 160 and the dark crushing part 170 are each such that the distance between the center of the central peak 111 and the center of the perforation 160 and the center between the central peak 111 and the center of the dark crushing part 170 are the same. By being installed, when the support 140 is rotated 180 ° by the rotating body 120, the positions of the perforations 160 and the crushing parts 170 are accurately changed.

 Therefore, when carrying out the work of crushing the rock, there is no need to replace the equipment to be installed in the backhoe, and the arm crushing unit 170 is accurately located in the center of the drilling hole (h) even if it is not checked visually. Since the traveling direction of the crushing portion 170 exactly matches the direction of the perforation hole h, the efficiency of the work is greatly increased as described above.

Next, each configuration of the rotating rock crushing apparatus 100 of the present invention will be described in detail.

As shown in Figures 2 and 4, the central body 110, which is a part of the rotating rock crushing apparatus, is provided with a central peak 111 at the distal end and is formed in a tubular shape.

The central body 110, as the rotating body 120 as a support means to be fixed to the rock while being the central axis for the rotation of the perforated portion 160 and the crushed portion 170, these perforated portions 160 And the exact location exchange between the crushing part 170.

At this time, the central peak 111 for fixing the center body 110 to the rock may have a fixed structure integrally with the front end of the center body 110 as shown in FIG. 4, as shown in FIG. The peak receiving portion 112 may be provided at the distal end of 110, and a separation structure may be provided in which the central peak 111 is built in the peak receiving portion 112.

In the latter separation structure, when the cross sections of the peak receiving portion 112 and the center peak 111 are formed in a circular shape, only the pivoting rock crushing device 100 is rotated while the center peak 111 is fixed to the rock surface. do. Therefore, when the central body 110 is rotated, there is no room for the central peak 111 to dig into the rock surface, so that the rotating rock crushing device 100 can maintain a more stable position fixing state.

In addition, a shock absorber 113 may be further embedded between the peak receiving portion 112 and the center peak 111. The shock absorber 113 absorbs the shock generated when the central body 110 advances and the central peak 111 is fixed to the rock surface, so as not to force the rotating rock crushing apparatus 100 itself, and perforate it. It absorbs this so that the vibration generated during work does not act on the central peak 111 to prevent the position of the central peak 111 from moving.

The shock absorbing material 113 need only have a sufficient restoring force, and there is no need to specifically limit the material. Most preferably, an elastic material such as a rubber sheet is used.

A rotation bearing 114 may be further provided between the shock absorber 113 and the center peak 111. The pivoting bearing 114 allows smooth rotation of the central body by preventing frictional force between the peak receiving portion 112 and the central peak 111 when the central body 110 rotates.

For easy installation of the rotation bearing 114, a support plate 117 with a bearing groove 117a may be provided at the rear end of the center peak 111 and the front end of the shock absorber 113, respectively.

The rotating body 120 is installed so that a part of the distal end or the tip overlaps the central body at the rear of the central body 110 and has the same tubular shape as the central body 110. The rotating body 120 is rotated by the fixed body 130, while rotating the central body 110 and the support 140, and at the same time, when the central body 110 and the support 140 move forward and backward, these central bodies ( 110) and serves to support the load of the support 140.

For this purpose, a rear gear 121 protruding outward is formed at a rear end of the rotating body 120. The external gear 121 is engaged with the driving gear 132a of the rotating motor 132, which will be described later, and rotates the rotating body 120 so that the support 140 and the central body 110 can rotate as described above.

The fixed body 130 is to provide the installation surface of the rotating motor 132 to transmit power to the external gear 121 while receiving the external gear 121, it is installed on the rear of the rotating body 120. Accordingly, a gear receiving portion 131 having a receiving space 131a is formed on the fixing body 130 so that the external gear 121 is inserted, and the outer surface of the gear receiving portion 131 is shown in FIG. 6. Likewise, a rotation motor 132 equipped with a driving gear 132a is installed.

The rotating motor 132 is a power source for rotating the rotating body 120 as described above, and the rotating motor in a state where the external gear 121 and the driving gear 132a in the receiving space 131a are engaged. When the 132 is operated, the external gear 121 is rotated while the driving gear 132a is rotated, and accordingly, the rotating body 120 is rotated.

At this time, by installing the ball bearing 133 between the inner surface of the gear receiving portion 131 and the outer surface of the external gear 121, the load of the fixed body 130 and other components, such as the rotating body 120, the support ( 140), the center body 110, the perforated portion 160, and the shredder 170 prevents the outer gear 121 from being inclined within the receiving space 131a due to the difference in the load acted by the shredding portion 170 It is preferable to allow the 121 to rotate smoothly.

The support 140 is also made of a tubular shape like the central body 110 and the rotating body 120, and is provided with a perforated portion 160 and a crushing portion 170, and rotates through the rotating body 120 as a medium.

The support 140 is to work to form a perforated hole (h) using the perforated portion 160, or to break the rock on the inner surface of the perforated hole (h) using the rock crushing portion 170 When doing so, the rotating rock crushing apparatus 100 of the present invention is advanced forward and fixed to the surface of the rock in order to maintain a stable fixed state.

 The support 140 may be installed on each outer surface of the rotating body 120 and the central body 110, or may be installed between the inner surface of the rotating body 120 and the outer surface of the central body 110. 2 and 4 show the former, and FIG. 12 shows the latter.

The cross section of the central body 110, the rotating body 120, and the support 140 may be formed in an angular shape, or may be formed in a circular cross section.

On the other hand, the support 140 is to be rotated together via the pivoting body 120. When the cross-sections of these are shaped like an electron, the support 140 includes the pivoting body 120 and the central body ( When installed on each outer surface of 110), the support body 140 rotates when the rotating body 120 rotates only by matching the inner end surfaces of the support 140 with the respective outer end surfaces of the rotating body 120 and the central body 110 ) Can also be rotated together.

However, when these cross-sections are configured as circular cross-sections as shown in the latter, as shown in FIG. 7, the inner cross-sections of the support 140 coincide with the respective outer cross-sections of the rotating body 120 and the central body 110. In addition, the locking grooves 145 are formed in the longitudinal direction on the inner end surface of the support 140, and the locking protrusions 115 and 125 are inserted into the locking grooves 145 on the outer surfaces of the rotating body 120 and the central body 110. You can make them rotate together through the method of forming each.

As described above, the support 140 is fixed to the rock surface by advancing before the perforation unit 160 and the rock crushing unit 170 are operated, so that the perforation unit 160 and the rock crushing unit 170 are It has a function of stably supporting the rotating rock crushing apparatus 100 of the present invention so that the action can be efficiently performed, and the support protrusion 141 is further added to the front end of the support 140 so that this function is more efficiently performed. It can be provided.

8 shows each embodiment of the support protrusion 141 described above.

The support protrusion 141 improves the fixing force of the support 140 to the rock surface, thereby preventing the rotation of the rotating rock crushing device 100 and the movement of the center body 110 during drilling, rotation, and rock crushing. As long as the structure is possible, it does not need to be particularly limited. For example, as shown in Fig. 8 (a), it may be formed to protrude in an uneven shape around the front end of the support 140, as shown in Fig. 8 (b), the circumference of the front end of the support 140 It may be formed in a pin shape.

In particular, as shown in (b) of FIG. 8, the support protrusions 141 formed in a pin shape are provided with a plurality of spaced apart from each other at the front end of the support 140, and the protrusion receiving space 142 at the rear end of each support protrusion 141. ), And by providing the elastic body 143 inside the protrusion receiving space 142, it is possible to have a sufficient fixing support against an uneven rock surface. That is, the support protrusion 141 provided with the monolithic body 143 at the rear is pushed backward by the protruding portion of the uneven rock surface, and the support 140 does not tilt or contact by the protruding portion and thus does not function properly. The elastic body 143 is easy to use as long as it is a material having elasticity, but is preferably made of a spring.

In the rear of the fixed body 130, while supporting the fixed body 130 so that the rotating rock crushing device 100 can be mounted on a backhoe, drilling and crushing work by the rotating rock crushing device 100 The fixing body 150 may be further installed to adjust the angle of the direction from side to side. The connection between the fixing body 130 and the mounting body 150 for this purpose is made of a pin coupling structure by a fastening bolt 152.

 At this time, as shown in FIG. 9 for adjusting the left and right angles, first side brackets 151 are installed on both sides of the fixing body 150, and second side brackets 134 on both sides of the fixing body 130. This is installed, the first side bracket 151 and the second side bracket 134 are connected by a horizontal correction hydraulic jack 200. Accordingly, when the horizontal correction hydraulic jack 200 on one side of the fixture 150 is increased and the horizontal correction hydraulic jack 200 on the other side of the fixture 150 is reduced, the angle of the fixture 130 relative to the fixture 150 changes and the rock The working direction of the rock crushing device 100 with respect to the surface is adjusted, so that an accurate operation can be achieved.

The perforation 160 is installed on one side of the support 140 and serves to form a perforation hole h on the rock surface. As shown in FIGS. 2 and 4, the perforation unit 160 is provided with a drifter body 161 installed on one side outer surface of the support 140 and a drifter body 161 installed on one surface. It consists of a guide piece 162, a perforated rod 163 protruding from the drifter body 161, and a bit 164 installed at the tip of the perforated rod 163.

In addition, a first rail 147a inserted into the first guide piece 162 is installed in the longitudinal direction of the support 140 on one outer surface of the support 140 for the front and rear movement of the perforation 160. Therefore, as the first guide piece 162 of the drifter body 161 slides along the first rail 147a, the perforated portion 160 is forward or backward along the first rail 147a installed on the support 140. Will move to

 At this time, in addition to guiding the forward and backward movement of the perforated rod 163, the perforated rod 163a at one end of the support 140 is prevented from being shaken during the forming process of the perforated hole h. It is preferable to further include a first guide bracket 148 provided with a guide hole 148a for insertion.

A chain may be used to move the front and rear of the perforation 160, but preferably, by installing a towing hydraulic jack 500 between the drifter body 161 and the first guide bracket 148, the towing hydraulic jack 500 ) To facilitate the maintenance by moving the perforated portion 160 by the expansion and contraction. The traction hydraulic jack 500 fixes the hydraulic rod appearing in the cylinder to the drifter body 161, thereby reducing the length of the traction hydraulic jack 500 so that the perforation 160 can move forward.

The rock crushing part 170 is inserted into the hole puncture hole h to crush the rock, and as shown in FIG. 10, the rock crusher 171 inserted into the hole h and the rock crusher 171 Direction motor 172 to rotate, the second guide piece 173 installed on one surface of the direction motor 172, and the direction motor 172 is installed in front of the crushing to operate the arm crusher 171 It is made of a hydraulic jack (174).

In addition, the second rail 147b is in the longitudinal direction of the support 140 in the opposite position to the other side of the support 140, that is, the perforation 160 in order to accurately move the crushing part 170 forward and backward. Is installed as Therefore, the second guide piece 173 into which the second rail 147b is inserted slides along the second rail 147b to move the arm crushing part 170 forward and backward.

An inner fixing bracket 601 is provided at the rear end of the support 140 on which the second rail 147b is installed in order to facilitate the front and rear movement of the arm crushing unit 170, and the inner fixing bracket 601 and the direction motor ( 172) is installed between the propulsion hydraulic jack 600. The propulsion hydraulic jack 600 expands and contracts the arm shredder 171 to move forward and backward. The propulsion hydraulic jack 600 is fixed to the rear of the hydraulic crusher 171, as opposed to the traction hydraulic jack 500, the hydraulic rod appearing in the cylinder, by extending the length of the propulsion hydraulic jack 600, the female crusher 171 By allowing to advance, it is possible to overcome the difference between the permissible length of the perforated portion 160 that is realistically generated and the insertable length of the arm shredder 171 of the arm breaker 170. However, the separation installation of the traction hydraulic jack 500 and the propulsion hydraulic jack 600 is only in accordance with the manufacture of a device for them or a range of conventional drilling and crushing, so as to show all of the hydraulic jacks 600 as shown in FIG. ), Or vice versa.

The rock crusher 171 expands the inner diameter of the perforation hole h formed by the perforation part 160 to cause cracks in the rock. The crushers 171 may be implemented in various structures as illustrated in FIGS. 11A and 11B.

For example, as shown in (a) of FIG. 11, a plurality of crushing protrusions 171a may be structured to protrude through the through hole 171b of the female crusher 171 by hydraulic pressure, or (b) of FIG. 11. It may be a wedge pressure structure using a wedge 175 and a reverse wedge 176 as shown in. However, since the crushing machine 171 of the above-described structure can crush the rock only to one side, the direction motor 172 can be used to convert the operating direction of the crushing protrusion 171a or the reverse wedge 176 to a required direction. There will be.

On the other hand, as the case of the crusher arm 171 is a wedge pressure structure, when installed to be guided by the guide hole 149a of the second guide bracket 149, the wedge action is limited according to the size of the inner diameter of the guide hole 149a Can be.
