Each of these methods is a blasting method using gunpowder, a vibration-free crushing method using hydraulic equipment, and a crushing method using breakers. Is being used. Among the above crushing methods, the blasting method is currently applied most widely in civil engineering and construction sites, but various civil complaints are caused by ground vibration and noise generated during blasting work. Therefore, underground space utilization in urban areas is being implemented by moving to the outskirts of the city where the rock blasting method is applicable or the ground where the blasting method can be applied, due to various restrictions and complaints. However, this also causes a lot of complaints due to unreasonable blasting work, causing a variety of problems, such as air delays and increased costs.

On the other hand, rock crushing by the breaker (Power Breaker) crushing method has been used for the second subdivision of hair crushed by the blasting work or other rock crushing method, rather than single construction by the breaker, but in recent years caused various complaints Therefore, it is applied to rock fracture. Rock breakage by these breakers is also generated by the continuous mechanical impact sound, which causes the civil complaints.

According to the above complaints, the technology of rock crushing method is being developed, and vibration and scattering are accompanied by damages to surrounding security items and residents, and vibration free vibration is used for the purpose of rock crushing in civil complaint areas. A method has been proposed.

Non-vibration-free fracturing method using hydraulic pressure controls pollution such as vibration, noise, and stone monuments, protects security objects adjacent to the site, prevents civil complaints without being restricted by weather conditions, and improves the efficiency of construction. It is widely used in rock tunnel tunnel excavation, drainage pipelines, cutting and crushing of reinforced concrete structures. In order to perform the vibration-free crushing method, it is required to drill the rock using a rock drilling machine and to crush the rock by inserting a rock drill into the drilled hole.

In this case, the perforated hole formed in the rock may not be formed at right angles to the rock wall, the longitudinal direction may not be constant, and the inner circumferential surface may not be smooth, and irregularities may be formed. Therefore, when inserting the haul rod into the drilling hole, the insertion direction of the haul rod should be changed appropriately in the up and down or left and right directions according to the longitudinal direction and the inner circumferential shape of the drilling hole. Conventionally, the haul rod is fixedly coupled to the excavator. There is a problem that the insertion direction of the haulbong is very difficult to change.

The rock crusher mounting unit according to the present invention includes a rock crusher 30 having a rock crusher 30 for forming a crack in a drilled hole 22 formed in the rock 20, and the boom 12 of the excavator 10. As a product for mounting on, the rock crusher 30 is not fixedly coupled to the boom 12, but the rock crusher 30 is fluidly boomed so that the rock crusher 30 can be rotated vertically and horizontally within a predetermined range. It is characterized in that it is composed of a structure bonded to (12). The rock crusher mounting unit according to the present invention for performing the above function, the first plate 100 is connected to the boom 12 of the excavator 10, the rock crusher 30 is coupled to the first plate It includes a second plate 200 coupled to the structure capable of rotating in the vertical and horizontal directions to the 100, and the rotation angle limiting part 300 for defining the vertical and horizontal rotation angle of the second plate 200 It is configured by.

Rotating coupling of the first plate 100 and the second plate 200 may use a rotating body capable of rotating up and down and left and right like the spherical bearing 130, the spherical bearing 130 is shown in FIG. As described above, the inner ring includes an outer ring 132 having a concave shape, and an inner ring 134 inserted into the outer ring 132 by having an outer surface formed on the inner circumferential surface of the outer ring 132. Is configured, the inner ring 134 is characterized in that it has a rotatable structure to freely change the direction of the central axis in the state coupled to the outer ring (132). The spherical bearing 130 is a connection medium for fluidly connecting two components such that the coupling angles of the spherical members can be freely changed. Any spherical bearing 130 can be applied to the present invention as long as it provides the same effect. In addition, as mentioned above, the second plate 200 coupled to the first plate 100 by a single rotating shaft to which the spherical bearing 130 is applied is maintained while being coupled to the first plate 100. It can be freely rotated up, down, left, and right directions around the bearing 130, the rotation of the second plate 200 will be described in detail with reference to the separate drawings below.

As such, when the second plate 200 is freely rotated in the vertical and horizontal directions, the rock crusher 30 coupled to the second plate 200 is also freely rotated in the vertical, horizontal directions. Lowered. Therefore, when inserting the haulbong 32 into the drill hole 22 formed in the rock as shown in Figure 1, the drill hole 22 formed in the rock is not formed at right angles to the rock wall or the drill hole Even if the longitudinal direction of the 22 is not constant or a stone or other metal having high strength protrudes from the inner circumferential surface of the drilling hole 22, the haul rod 32 has a longitudinal direction so as to avoid the stone or the metal. Since it can be changed automatically, there is an advantage that the operator does not need to change the insertion direction of the haul bar 32 one by one. That is, when the rock crusher mounting unit according to the present invention is used, even if the boring holes 22 formed in the rock are not formed at right angles to the rock wall or the longitudinal direction of the boring holes 22 is not constant, the rock rods The direction 32 is adjusted along the longitudinal direction of the drilling hole 22 can be inserted into the drilling hole 22, the stone rod 32 inserted into the drilling hole 22 is a stone or metal of high strength When in contact with the insertion direction is automatically changed so as to deflect the stone or metal bar, there is an advantage that the insertion of the haul bar 32 is very easy.

In this case, when the haul rod 32 is rotated at an excessive angle, the haul rod 32 may be broken or a case in which normal insertion may not be possible. Thus, the rock crusher mounting unit according to the present invention has a Rotating angle limiting unit 300 for limiting the rotation angle within a predetermined range is provided. As shown in FIG. 4, the rotation angle limiting part 300 includes a first stopper 310 protruding from the first plate 100 toward the second plate 200 (downwardly in this embodiment), And a second stopper 320 protruding from the second plate 200 toward the first plate 100 (upwardly in this embodiment) and positioned to the side of the first stopper 310.
As such, the first stopper and the second stopper are configured to engage with each other up and down to limit the first plate and the second plate not to exceed the maximum rotatable point.

In this case, an end of the first stopper 310 is spaced apart from an upper surface of the second plate 200, and an end of the second stopper 320 is formed to be spaced apart from a bottom of the first plate 100. The plate 200 and the rock crusher 30 coupled thereto have an end of the first stopper 310 contacting an upper surface of the second plate 200 or an end of the second stopper 320 of the first plate 100. Up and down rotation is possible only within the range in contact with the bottom. In addition, the second stopper 320 located on the side of the first stopper 310 is set to be spaced apart from the first stopper 310 by a predetermined distance, and the second plate 200 and the rock crusher coupled thereto ( 30 may rotate left and right only within a range where the second stopper 320 interferes with the first stopper 310. That is, as shown in the present embodiment, when the first stopper 310 and the second stopper 320 are provided, the second plate 200 and the rock crusher 30 coupled to the first stopper 310 are coupled to the first stopper ( Since the rotation angle is limited by the 310 and the second stopper 320, the excessive rocking rod 32 may be prevented from being excessively rotated.
As described above, the first stopper 310 and the second stopper 320 freely move in accordance with the bending of the drill hole and serve to prevent excessive rotation in the process of seating the drill hole. The technical idea is to restrict the rotation economically and effectively through the interfering and interlocking structure between the protrusions without any special mechanism. The rotation range can be adjusted by adjusting the installation position, size and angle.

On the other hand, the first plate 100 and the second plate 200 while maintaining the state spaced apart from each other so that the spherical bearing 130 can be coupled to the connecting medium, the second plate 200 from the first plate 100 A first hinge block 110 extending toward the first and second pairs of the second hinge block 110 extending from the second plate 200 toward the first plate 100 and positioned on the left and right sides of the first hinge block 110.

Therefore, the longitudinal direction of the fastening shaft 140 can be freely changed in the vertical direction and the left and right directions around the spherical bearing 130, a pair of second ends of the fastening shaft 140 are coupled in a fitting manner Hinge block 210 is also rotated along the fastening shaft 140. That is, the second plate 200 and the rock crusher 30 coupled thereto may not only be rotated about the longitudinal center of the fastening shaft 140 with the rotation axis, but may also be horizontally and diagonally around the spherical bearing 130. Since the direction can be changed, the rock rod 32 provided in the rock crusher 30 can be changed in any direction.

On the other hand, the rock crusher mounting unit according to the present invention, even if the drilling hole 22 formed in the rock is not formed at right angles with respect to the rock wall or the longitudinal direction of the drilling hole 22 is not a constant rock rod 32 ), The first plate 100 can be freely rotated within a certain range so that the insertion direction can be automatically adjusted and the haul rod 32 can be inserted while deflecting stone or metal. However, in some cases, a situation may arise in which the direction of the first plate 100 and the rock crusher 30 coupled thereto is fixed. Therefore, the rock crusher mounting unit according to the present invention pulls up the first hinge block 110 upwards so that the first plate 100 can be fixed without being shaken, and the first stopper 310 has the second plate ( The momentary fixed cylinder 150 may be further provided to be in close contact with the 200 or the second stopper 320 is in close contact with the first plate 100.

In addition, the rock crusher mounting unit according to the present invention, the bracket 14 is mounted on the boom 12 of the excavator 10, so that the upper plate can also be rotated, one side (in this embodiment, the upper side) is the bracket 14 Connection ring plate 400 is fixedly coupled to the inner ring gear 410 is coupled to the inner circumferential surface of the connection ring plate 400, the drive ring is coupled to the gear formed on the inner peripheral surface of the inner ring gear 410 Gear 420 and a swing motor 430 for rotating the drive gear 420 to rotate the drive gear 420 is further provided, the first plate 100 is the inner ring gear 410 and It can be configured to be integrally coupled. When the bracket 14 and the first plate 100 are coupled to the connection ring plate 400 and the inner ring gear 410 as a connecting medium, the swing motor 430 is driven to rotate the drive gear 420. The connection ring plate 400 integrally coupled to the bracket 14 maintains a fixed state, and the inner ring gear 410 and the first plate 100 coupled thereto are centered on the rotation axis of the inner ring gear 410. As it is rotated to, the user can rotate the first plate 100 and the rock crusher 30 coupled thereto by controlling the operation of the swing motor 430 as a whole in the left and right directions. In this case, when the swing motor 430 protrudes outward, the swing motor 430 may collide with debris or other objects generated in the process of crushing the rock, which may damage and break the swing motor 430. It is preferable to be mounted on the bottom surface, that is, mounted between the connection ring plate 400 and the first plate 100 so as not to protrude to the outside.

In addition, the user can rotate the first plate 100 and the rock crusher 30 coupled thereto as a whole in the vertical direction, so as to be connected to the inner ring gear 410 to form a horizontal axis of rotation in the first plate 100. Fixed hinge block 440 is coupled to the center rotatable structure, and the lifting hinge block 450 and the first both sides of the longitudinal hinge connected to the inner ring gear 410 for adjusting the rotation angle of the fixed hinge block 440 An angle adjustment cylinder 460 hinged to the plate 100 may be further provided. One side of the inner ring gear 410 (rear side in this embodiment) is coupled to the first plate 100 in a rotatable structure, and the other side of the inner ring gear 410 (front side in this embodiment). When connected to the first plate 100 by the separate angle adjustment cylinder 460, the user expands or compresses the angle adjustment cylinder 460 of the first plate 100 and the rock crusher 30 coupled thereto The vertical angle can be adjusted freely. At this time, when the first plate 100 is rotated up and down by expansion or compression of the angle adjustment cylinder 460, the angle adjustment cylinder 460 so that the first plate 100 does not tilt to the left or right. As shown in this embodiment is preferably provided with one on both sides in the width direction of the first plate (100).

As mentioned above, when the first plate 100 is rotatable in the horizontal and vertical directions based on the bracket 14, the user does not adjust the overall position or the overall function and direction of the excavator 10. Even if only the overall direction and position of the boom 12, the swing motor 430 and the angle cylinder are controlled, the longitudinal direction of the arm rod 32 can be adjusted to the depth direction of the drilling hole 22. In addition, when the excavator 10 operates the position or the overall function to adjust the longitudinal direction of the arm rod 32, the swing motor 430 and the angle cylinder to adjust the longitudinal direction of the arm arm 32 Since the angle of the haul rod 32 can be finely adjusted, the workability is remarkably improved.

Meanwhile, in the present exemplary embodiment, only the case where the rock crusher 30 having the rock rod 32 is mounted on the first plate 100 is illustrated, but the device mounted on the first plate 100 is a rock rod ( In addition to the rock crusher 30 having a 32) it can be replaced by a variety of devices. That is, the rock crusher 30 is not only a rock crusher that generates a crack in the drill hole 32 using a plurality of hydraulic cylinders as shown in the present embodiment, but also a drill hole 32 using the wedge principle. It can be replaced by a rock crusher having various structures such as a rock crusher that generates a crack.

6 to 8 are side views of an operation example in which the rock crusher rotates up and down, FIG. 9 is a side view showing an operation example in which the rock crusher is fixed, and FIGS. 10 to 12 are cut along the line AA shown in FIG. 6. As a flat sectional drawing, the shape by which a rock crusher rotates left and right is shown.

6 and 10 illustrate embodiments of the first and second stoppers, in which the first stopper 310 is spaced apart from the second plate 200, and the first stopper 310 and the second stopper are separated from each other. As the state 320 is spaced apart from each other, the second plate 200 and the rock crusher coupled thereto is an initial state that can be freely rotated vertically and horizontally.

In the state shown in FIG. 6, when the haul rod 32 is lifted up at an angle, as shown in FIG. 7, the end of the front first stopper 312 is in contact with the upper surface of the second plate 200. The haulbong 32 is no longer lifted up. On the contrary, when the haul rod 32 is lowered by a certain angle in the state shown in FIG. 6, the end of the rear first stopper 314 is in contact with the upper surface of the second plate 200 as shown in FIG. 8. , The haulbong 32 is no longer down. That is, when the rock crusher 30 is mounted on the excavator 10 using the rock crusher mounting unit according to the present invention, the upper surface of the second plate 200 is in contact with the end of the front first stopper 312 or rearward. Since the rock crusher 30 can be rotated up and down only until it is in contact with the end of the side first stopper 314, it is possible to prevent excessive vertical rotation of the rock crusher 30.

At this time, in the present embodiment, when the second plate 200 and the rock crusher 30 coupled thereto are rotated in the vertical direction, the first stopper 310 contacts the upper surface of the second plate 200 so that the rock crusher 30 Although only the case of limiting the vertical rotation of the) is shown, the second stopper 320 is formed longer than the first stopper 310 so that the second plate 200 and the rock crusher 30 coupled thereto in the vertical direction When rotated, the second stopper 320 may be in contact with the bottom of the first plate 100 to limit the vertical rotation of the rock crusher 30.

In addition, at least one of the first stopper 310 and the second stopper 320 may have a structure in which the protruding distance is adjustable so that the vertical rotation allowable angle of the rock crusher 30 may be increased or decreased. When the protruding distance of the first stopper 310 or the second stopper 320 is configured to be adjustable as described above, the user increases the protruding distance of the first stopper 310 or the second stopper 320 to increase the rock crusher 30. ) Rotates only a little in the vertical direction, so that the first stopper 310 or the second stopper 320 is in contact with the second plate 200 or the first plate 100, and the first stopper 310 or the second stopper By reducing the protruding distance of the 320, the rock crusher 30 has to be rotated more in the up and down direction so that the first stopper 310 or the second stopper 320 is not attached to the second plate 200 or the first plate 100. By being in contact, there is an advantage that the rock crusher 30 can be easily adjusted the range of the allowable angle to rotate in the vertical direction.

On the other hand, when the haulbong 32 is rotated to the left by a predetermined angle in the state shown in FIG. 10, the front second stopper 322 located on the left side as shown in FIG. 11 is the front first stopper 312. And the rear side second stopper 324 located on the right side interfere with the rear side first stopper 314, so that the haulbong rod 32 is no longer rotated to the left side. On the contrary, when the haul rod 32 is rotated to the right by an angle in the state shown in FIG. 10, the front second stopper 322 positioned on the right side is the front first stopper 312 as shown in FIG. 12. The second side stopper 324 which is located on the left side and interferes with the first side stopper 314 interferes with the arm rod 32 so that it can no longer be rotated to the right side. That is, when the rock crusher 30 is mounted on the excavator 10 by using the rock crusher mounting unit according to the present invention, the rock crusher 30 only until the first stopper 310 and the second stopper 320 are in contact with each other. ) Can be rotated left and right, it is possible to prevent excessive left and right rotation of the rock crusher (30).

At this time, even if only the front first stopper 312 and the front second stopper 322 is provided, it is possible to limit the left and right rotation of the rock crusher 30, in this case, the rotational stress of the rock crusher 30 in the front Since the concentration is concentrated on the side first stopper 312, the front side first stopper 312 may be damaged. Therefore, the first plate 100 is provided with a front side first stopper 312 and a rear side first stopper 314 located in front and rear of the point where the spherical bearing 130 is located, and the second plate ( The pair of front side second stoppers 322 positioned on the left and right sides of the front side first stopper 312 and the pair of rear side second stoppers positioned on the left and right sides of the rear side first stoppers 314 are provided in the 200. Preferably, 324 are provided.

On the other hand, so that the left and right rotation allowable angle of the rock crusher 30 can be increased or decreased, the separation distance between the pair of front second stopper 322 and the pair of rear second stoppers 324 are adjusted to each other. It can be mounted in any possible structure. As such, when the mutual separation distance between the pair of front second stoppers 322 and the mutual separation distance between the pair of rear second stoppers 324 are configured to be adjustable, the user may use the pair of front second stoppers. The mutual separation distance between the 322 and the mutually separated distance between the pair of rear second stoppers 324 may be increased to allow the rock crusher 30 to be more rotatable in the left and right directions, and vice versa. By narrowing the mutual separation distance between the second stoppers 322 and the mutual separation distance between the pair of rear second stoppers 324, the rock crusher 30 may be rotatable only at a smaller angle in the left and right directions.

At this time, as a method of changing the mutual separation distance between the pair of front second stoppers 322 and the mutual separation distance between the pair of rear second stoppers 324, the front second stopper 322 and the rear A method of replacing the side second stopper 324 with parts having different thicknesses may be applied, and a guide rail (not shown) may be installed on the second plate 200 and the front second stopper 322 and the rear second side may be installed. A method of mounting the stopper 324 to the guide rail may be applied. As such, the technical idea of changing the separation distance between two components is widely used in the technical field corresponding to the present invention, and a detailed description thereof will be omitted.
