Description

Removable rock crusher {ROCK CRUSHING DEVICE THAT CAN REPLACE DRILLING DEVICE AND CRUSHER}

The present invention relates to an apparatus for crushing rock that appears during the process of excavating the ground to construct an underground structure such as a tunnel, and more specifically, by using a physical pressurization method, vibration and dust are not generated and the generation of noise is minimized It relates to a rock crushing device that enables efficient excavation and removal of rock with little force.

During the underground excavation process for an underground tunnel, the operation of excavating or removing the rock may be accompanied. A representative method of excavating such rock is the drill & blast method (Drill & Blast Method). However, this blasting method not only causes many civil complaints due to noise and vibration, but also causes environmental damage and safety accidents.

Therefore, in order to solve this problem, a perforation hole is formed in the bedrock with a perforation facility, and a rock crushing device such as a halam is inserted into the perforation hole to expand the perforation hole, thereby forming a crack in the bedrock and allowing it to be crushed, thereby making noise or vibration. The use of methods to minimize the occurrence is increasing.

However, these drilling operations and rock crushing operations are carried out using separately manufactured equipment. For example, after forming a drilling hole in the rock using a rock drill such as a jumbo drill, the jumbo drill is withdrawn, the female crusher 30 is installed in equipment such as backhoe, and the female crusher 30 is inserted into the drilling hole. The crushing operation is carried out by expanding the perforation hole. Therefore, many heavy equipment such as jumbo drills and backhoes have to be used alternately, which not only increases the construction cost but also increases the construction period.

In order to solve this problem, a dark crushing device equipped with a drilling device and a dark crushing device has been proposed as a 'multi-splitter' through Korean Patent Publication No. 10-1666994.

As shown in FIG. 1, the multi-splitter of the registration number 10-1666994 includes an arm fastening part 100 fastened to the arm end of an excavator or hydraulic drill, and hinged from the front side of the arm fastening part 100, and the arm fastening part ( A rotating plate 200 rotating in the left and right transverse directions around 100), a support shaft 300 fastened to the lower portion of the rotating plate 200 to support and support the rock, and a rotating plate from the front of the rotating plate 200 ( 200) and a slider (S) hinged to rotate clockwise or counterclockwise around the rotating plate 200, and first and second guide frames constructed on one side and the other side of the slider (S), respectively ( 400 and 550) and the first and second guide frames 400 and 550, respectively, and the rock drilling machine 510 and the rock drilling machine 610 are included.

However, the multi-splitter of registration No. 10-1666994 described above is nothing more than a parallel arrangement of a pressure-wearing device 510 and an arm-spinning device 610 that are each independently configured and operated, and the overall equipment size is inevitably large and heavy. There is a problem in that operation equipment is required, operation and management thereof are complicated, and manufacturing cost is increased.

That is, by installing an external gear on the drive shaft of the second rotation motor 141 and installing an internal gear at the end of the vertical rotation part 130 , the bent end 133 of the vertical rotation part 130 as a central axis is a horizontal rotation part. (140) together with the guide carrier 16 can be rotated left and right. At this time, the bent end 133 of the vertical rotation portion 130 serving as the central axis should have a shape perpendicular to the portion connected to the fixing table 11 .

By further providing the inclination adjustment jack 150 between the horizontal rotation unit 140 and the support unit 120, the direction of drilling and crushing for the free surface of the bedrock can be set more freely.

FIG. 5( c ) is a diagram illustrating the adjustment of the inclination angle of the guide moving table 16 by the inclination adjusting jack 150 . As shown in this figure, in a state in which the horizontal rotation part 140 and the support part 120 are combined in a hinge structure, the inclination adjustment jack 150 is stretched and contracted by the perforator 20 or the shredder 30 is installed on the guide carrier ( 16) can be adjusted in the required inclination direction.

The guide carrier 16 is provided with a contact body 161 at the tip, and is coupled with the support 120 so as to be able to slide forward and backward on the upper surface of the support 120 as shown in FIG. 6 .

A lower rail groove 164 is provided in the guide carrier 16 to enable the sliding operation of the guide carrier 16 , and the support unit 120 coupled thereto has a sliding key to be inserted into the lower rail groove 164 . A guide block 121 provided with 122 is installed. In addition, a hydraulic jack 123 is installed on the support 120 as a driving means for moving the guide holder 16 . The rod end of the moving table hydraulic jack 123 is hinged to the guide moving unit 16 .

Therefore, when the mobile platform hydraulic jack 123 is extended, the guide carrier 16 moves forward while riding on the guide block 121 of the support unit 120 to bring the contact body 161 provided at the tip into close contact with the free surface of the bedrock. to allow the perforator 20 or the crusher 30 to stably perforate or crush crushing pressure.

As shown in Fig. 7, the moving bogie 17 is installed in the guide moving table 16 to be able to slide forward and backward, and the perforator 20 or the crusher 30 is detachable from the moving bogie 17. installed to enable In addition, an operation motor 173 for rotating the perforator 20 and the crusher 30 is installed in the moving cart 17 .

Therefore, the moving bogie 17 moves the drilling machine 20 and the crusher 30 forward and backward and rotates them so that the drilling operation and the crushing operation can be performed efficiently.

In order to enable the sliding operation of the moving bogie 17, the guide moving table 16 is provided with an upper rail groove 163, and the moving bogie 17 coupled thereto is inserted into the upper rail groove 163. A guide block 171 provided with a sliding key 172 is installed. In addition, a driving means is installed between the moving bogie 17 and the guide moving stand 16 to move the moving bogie 17 such as a hydraulic bogie hydraulic jack 162 or a chain forward and backward.

On the other hand, the above-described perforator 20 is made of a long perforating rod 21 and a bit 22 attached to the tip of the perforating rod 21, and the crusher 30 is also a long crushing rod ( 31) and the protrusion pieces 32 or wedges protruding from the outer surface of the crushing rod 31. The protrusion piece 32 to the wedge are operated by hydraulic pressure, and a hydraulic hose (not shown) for this is connected to the crushing rod 31 .

The punching rod 21 and the crushing rod 31 are drilled or crushed while moving forward and backward in a state in which the rear end is mounted only on the drive shaft 174 of the operation motor 173 .

A mounting piece 165 for guiding the correct forward and backward movement of the drilling rod 21 and the crushing rod 31 while preventing the sagging of the perforating rod 21 and the crushing rod 31 may be further installed on the guide moving table 16 . FIG. 8 shows an embodiment of the mounting piece 165 .

The mounting piece 165 is provided with a seating hole or seating groove 167 for seating the punching rod 21 or the crushing rod 31 . However, the detachable arm shredding device of the present invention is to alternately attach and detach the perforator 20 and the shredder 30 so that the arm shredding operation can proceed. It is preferable to provide the mounting piece 165 with a seating groove 167 having an open top so that the rod 21 and the crushing rod 31 are easily drawn in. When the mounting groove 167 with an open upper portion is provided in the mounting piece 165, a cover piece 168 capable of closing the upper portion may be further provided, and in this case, the cover piece 168 is the mounting piece ( 165), such as to have a structure hinged to the opening and closing of the seating groove 167 should be selectively possible.

9 to 13 respectively show embodiments relating to the attachment and detachment of the perforator 20 and the crusher 30 and deceleration of the rotational speed, FIG. 9 is a moving bogie 17, more specifically, on the moving bogie 17 With respect to an embodiment of attaching and detaching the perforator 20 or the crusher 30 to the drive shaft 174 of the installed operating motor 173, FIGS. 10 to 13 are embodiments in which the deceleration means of the crusher 30 is further added Each is shown with respect to an example.

The mounting of the perforator 20 and the crusher 30 to the drive shaft 174 of the actuating motor 173 may be by a direct connection method, or may be through the coupler 40 . In addition, their connection may be made by the insertion structure method of the multi-section, or it may be made by the screw fastening method. In the case of the screw fastening method as in the latter, it is preferable to fasten the fixing bolts 50 therebetween so that the connection is not loosened during reverse rotation, as shown in FIG. 9(b).

The rotation of the perforator 20 and the crusher 30 is made by the operation motor 173, but their respective rotations have different functions. Whereas the rotation of the perforator 20 is to continuously rotate the bit 22 to form a perforation hole in the rock, the rotation of the crusher 30 is the protrusion 32 or wedge protruding from the crushing rod 31 direction, that is, to set the pressing position of the inner surface of the drilling hole. Therefore, by applying the rotation of the perforator 20 having a high rotation speed to the crusher 30 as it is, the crusher 30 may be rotated so that the protrusion piece 32 or the wedge protrude to the pressing position on the inner surface of the bore hole, but this It requires high skill.

Therefore, in another embodiment of the present invention, by slowing down the fast rotation speed by the drive shaft 174 of the actuating motor 173 so that the rotation of the perforator 20 is made slowly, the exact direction of the protrusion 32 or the wedge is determined. A deceleration means for easy adjustment is further provided.

The reduction means may be a gear means, but it is made of a complex coupling structure of a plurality of large and small gears, and there is a problem in that a large space gearbox is required. Therefore, most preferably, the reduction means may be built in the coupler 40 for connecting the drive shaft 174 and the crusher 30, thereby eliminating the need for a separate gearbox.

One embodiment of the reduction means provided in the coupler 40, as shown in FIGS. 10 to 11 , consists of a support control body 60 , a reduction rotation body 80 , and a drive rotation body 70 . In addition, a spring 90 is installed between the support control body 60 and the deceleration rotation body 80 .

The support control body 60 is installed inside the coupler 40 to support the spring 90 so that the deceleration rotating body 80 can move forward and backward by the elastic force of the spring 90 . However, with respect to the rotating direction, the coupler 40 and the decelerating rotating body 80 must rotate with integrity. Therefore, coupling means (not shown) for allowing the coupler 40 and the decelerating rotating body 80 to mutually slide only in the longitudinal direction, such as a long groove in the longitudinal direction and a protrusion inserted therein, is provided in each of the coupler 40 and the decelerating rotating body 80 in contact with each other. should be

A support step 41 is formed on the inner surface of the coupler 40 so that the support control body 60 is supported and fixed by the coupler 40 .

The driving rotating body 70 is fixed to the driving shaft 174 of the operating motor 173 so that the rotational force of the operating motor 173 is transmitted to the crushing rod 31 through the coupler 40, while the coupler 40 It should be coupled with the coupler 40 so that the rotation speed with the coupler 40 can be changed without being separated from the coupler. As one embodiment for this, as shown in FIGS. 11 (a) and (b), a ring-shaped fixed circumferential groove 72 is provided on the outer circumferential surface of the driving rotor 70, and the tip of the coupler 40 is is provided with a fixing jaw 42 inserted into the fixing circumferential groove 72 .

The decelerating rotating body 80 reduces the rotational speed of the driving rotating body 70 and then transferring it to the coupler 40 , and the spring 90 and the actuating motor 173 having one end fixed to the support adjusting body 60 . ) is located inside the coupler 40 between the driving rotating body 70 having one end fixed to the driving shaft 174 .

In addition, the driving protrusion 71 and the driven protrusion 81 of the wedge cross-section are provided on each of the opposite surfaces of the driving rotor 70 and the decelerating rotation body 80 , respectively, as shown in FIG. 11 ( b ). The number of the driving protrusions 71 and the driven protrusions 81 installed depends on the degree to which the deceleration is desired. The driving protrusion 71 and the driven protrusion 81 are not formed on the respective front surfaces of the driving rotator 70 and the decelerating rotator 80 opposing each other to have flat surfaces 73 and 82 .

These driving protrusions 71 and driven protrusions 81 reduce the rotational speed of the operating motor 173 so that the crushing rod 31 can rotate at a gentle and appropriate speed.

12 is a view showing that the rotational speed of the driving rotator 70 is reduced by the driving protrusion 71 provided on the driving rotator 70 and the driven protrusion 81 provided on the decelerating rotator 80 to reduce the rotational speed of the decelerating rotator 80. The principle of operation of rotating is explained.

Figure 12 (a) shows a state in which the driving motor 173 is not operated and the driving rotating body 70 is stopped. In this state, the deceleration rotating body 80 has a state closest to the driving rotating body 70 by the pressing force of the spring 90 . At this time, the tip of at least one of the leading end of the driving protrusion 71 of the driving rotor 70 and the leading end of the driven projection 81 of the decelerating rotating body 80 is the flat surface 82 of the decelerating rotating body 80 or the driving rotating body ( 70) in a state in contact with the flat surface 72 .

12 (b) to (d) show the driving protrusion 71 of the driving rotating body 70 and the driven protrusion of the decelerating rotating body 80 while the driving rotating body 70 is rotated by operating the operating motor 173 . (81) shows a series of processes in which the relationship between the two is changed.

When the driving rotor 70 is rotated by the operation of the actuating motor 173, the side surfaces of the wedge cross-sections of the driving protrusion 71 and the driven protrusion 81 are gradually brought into contact with each other (Fig. 12 (b)). The driving protrusion 71 pushes the driven protrusion 81 (FIG. 12(c)). Since the rotational force of the driving protrusion 71 is transmitted to the driven protrusion 81 as it is until the driving protrusion 71 pushes the driven protrusion 81, the driven protrusion 81 also rotates with the coupler 40 and connected thereto. The crushing rod 31 is rotated.

However, when the driving protrusion 71 completely pushes the driven protrusion 81 and rides over it, as in the initial state, the tip of the driving protrusion 71 of the driving rotor 70 and the driven protrusion ( 81) At least one tip of the front end is in a state in contact with the flat surface 82 of the decelerating rotation body 80 or the flat surface 72 of the driving rotation body 70. During this predetermined period, the drive rotation body 70 ), the rotational force is not transmitted to the deceleration rotating body 80 (FIG. 12(d)). Therefore, the deceleration rotating body 80 rotates the rotational speed of the driving rotating body 70 in a reduced state by that much while rotating the crushing rod 31 slowly.

Between the coupler 40 and the support adjustment body 60, a means for adjusting the amount of the pressing force of the spring 90 may be further provided.

The time of the process in which the driving protrusion 71 pushes the driven protrusion 81 is determined by the spring 90 installed between the decelerating rotating body 80 and the supporting adjusting body 60 to drive the decelerating rotating body 80 to the driving rotating body 70 . ) depends on the size of the pressing force that pushes it toward the For example, when the pressing force of the spring 90 is increased, the side surfaces of the wedge sections of the driving projection 71 and the driven projection 81 are in contact with each other for a longer time than when the pressing force of the spring 90 is decreased. will keep Therefore, when the pressing force of the spring 90 is increased, the degree of deceleration is reduced, and when the pressing force is weakened, the degree of deceleration is increased.

13 shows an embodiment of the pressing force magnitude adjusting means of the spring 90 described above. According to this, the pressing force size adjusting means is configured to adjust the position of the support adjusting body 60 supporting the spring 90 . To this end, the support control body 60 is provided with a force adjusting bar 61 is installed, and the coupler 40 is provided with a force adjusting slit 43 into which the force adjusting bar 61 is inserted to move forward and backward. The force control slit 43 may further include locking grooves 44 at regular intervals.

According to this configuration, when the force adjusting bar 61 is moved toward the driving rotation body 70 as in FIG. 14 (a), the spring 90 is more compressed, so that when the driving rotation body 70 rotates, it is driven The side surfaces of the wedge cross-sections of the projection 71 and the driven projection 81 maintain a contact state for a long time to increase the rotational speed of the deceleration rotating body 80 .

However, on the contrary, when the force adjusting bar 61 is moved away from the driving rotation body 70, as in FIG. 14(b), the pressing force of the spring 90 is reduced and the driven protrusion 81 is moved to the driving protrusion ( Since it can be easily separated from the 71), the time during which the side surfaces of the wedge cross-sections of the driving protrusion 71 and the driven protrusion 81 are in contact with each other when the driving rotating body 70 rotates is reduced. Accordingly, the rotational speed of the decelerating rotating body 80 is reduced.

In the above, the present invention has been described in detail with reference to specific embodiments, but since the embodiments are merely examples for easy understanding of the present invention, those of ordinary skill in the art should be within the scope of the technical spirit of the present invention. It is obvious that it can be implemented with various modifications within. Accordingly, such modifications will be said to be within the scope of the present invention as described in the claims.
