Description

Elevator box for tunnel construction {ELEVATING BOX FOR EXCAVATING TUNNEL}

An embodiment of the present invention relates to an elevator for tunnel construction.

In general, a charging car is used for tunnel excavation during tunnel construction. Tunnel excavation work is being performed by approaching the target of the tunnel work with a drilling device or an explosive device for tunnel excavation in the charging car. In addition, Haambong has been used to carry out breaking, and has not been used during tunnel excavation. However, due to various advantages, a construction method has been developed to be used in excavation for constructing a tunnel of Halambong. However, in order for Halambong to be used for tunnel construction, the worker who works through Halambong must approach the excavation surface of the tunnel and the worker must be very close to the excavation work space. Therefore, the worker is exposed to the risk of rockfall occurring during the excavation process, and thus a solution is needed. In addition, since the scale of tunnel excavation is considerable, it is necessary to work at a high place, but there is also a need for a plan to reach a high place at the time of haambong work.

To this end, work may be performed through an elevated ladder or a vehicle equipped with an elevated rail. However, when a worker boards the workbench of such a vehicle, the problem of still being exposed to the danger that occurs during the excavation process is not solved. In addition, in order to work on Halambong, it is necessary to keep Halambong close to the tunnel excavation surface, but a considerable amount of physical energy is required for the worker to do this.

In addition, terms to be described later are terms defined in consideration of functions in the present invention and may vary according to the intention or custom of users or operators. Therefore, the definition should be made based on the contents throughout the present specification.

The technical idea of the present invention is determined by the claims, and the following embodiments are only one means for efficiently describing the technical idea of the present invention to those of ordinary skill in the art.

1 is a perspective view showing a tunnel construction elevator 10 according to an embodiment of the present invention.

Referring to Figure 1, the tunnel construction elevator 10 is a floor plate 11 for providing a working space to the operator, a frame 12, a frame that forms the outer frame of the tunnel construction elevator 10 It may include a top plate 13 covering the upper side of the bottom plate, a protective railing 14 formed on the top of the bottom plate along the circumference of the bottom plate to protect the worker inside. The elevator box 10 for tunnel construction is made of a metal material, especially a steel material, so that workers can be sufficiently protected from safety accidents that may occur during work.

The elevator box 10 for tunnel construction may be particularly used in the operation of enabling tunnel excavation by utilizing the halambong 100 during tunnel construction. When excavating a tunnel, in order to enable excavation to the upper part of the tunnel, it is necessary to enable the operation at a sufficiently high place. To this end, a vehicle equipped with an elevated ladder or an elevated rail may be used, and the elevator box 10 for tunnel construction according to an embodiment of the present invention can be attached to and detached from the worktable of such an elevated ladder or an elevated rail. . In this way, a state in which the elevator box 10 for tunnel construction is installed on the work table of the vehicle 20 equipped with an expensive rail is shown in FIG. 4. Referring to FIG. 4, the elevator box 10 for tunnel construction is installed on an elevated ladder mounted on the vehicle 20 or on a working table of an elevated rail, so that tunnel excavation work can be performed even on a high part of the tunnel. In addition, a generator 50 or the like may be connected to the Halambong for the operation of the Halambong. The tunnel construction method using Halambong will be described in more detail with reference to FIGS. 6 and 7.

In addition, since it is difficult to manufacture a separate work vehicle for the construction method using a halam rod for tunnel construction, the elevator box 10 for tunnel construction according to an embodiment of the present invention is a commonly used expensive ladder or expensive It is desirable to facilitate attachment and detachment so that it can be applied to a vehicle equipped with a rail.

Again, referring to FIG. 1, a coupling part 16 may be formed in order to allow the elevator box 10 for tunnel construction to be installed on an elevated ladder or a workbench of an elevated rail. The coupling portion 16 is, for example, a clamp (clamp) structure can be easily attached and detached from the work table.

As described above, the elevator box 10 for tunnel construction may provide a work space in which the halambong 100 is inserted into a surface for excavating the tunnel so that the tunnel can be excavated through a halam operation. Accordingly, an opening 17 may be formed on one side of the elevator box 10 for tunnel construction so that the halam rod 100 can perform halam operation. The halambong 100 is exposed through the opening 17 and the exposed halambong 100 enters the tunnel excavation surface, and the tunnel construction on the tunnel excavation surface may be performed by the halam operation.

FIG. 2 is a front view of the elevator box 10 for tunnel construction according to FIG. 1.

Referring to FIG. 2, on the bottom surface 11 of the elevator box 10 for tunnel construction, a halam rod holder 150 capable of mounting a halam rod 100 used for tunnel construction may be formed. In Fig. 2, the number of Halambong 100 and Halambong cradle 150 is shown in a group of 6, and accordingly, 6 Halambong cradle 150 is installed, but the number of Halambong 100 and Halambong cradle 150 is limited to this. It doesn't work. However, in order to facilitate the halam operation, it is preferable that a plurality of halam rods 100 are used, and thus a plurality of halam rod holders 150 may also be formed.

3 is a side view of the elevator box 10 for tunnel construction according to FIG. 1.

Referring to FIG. 3, the upper plate 13 formed on the upper side of the frame 12 that forms the outer frame of the tunnel construction lift box 10 may be for the safety of the worker boarding the tunnel construction lift box 10. have. For the safety of the operator, a safety net 15 may be additionally formed on the lower side of the upper plate 13. The safety net 15 may be formed in the form of a net capable of blocking large-sized rocks in order to protect workers from accidents such as falling rocks that may occur during tunnel construction.

5 is a view showing a haambong 100 used in the elevator for tunnel construction (10).

Referring to FIG. 5, the halam rod 100 may include a cylinder 120 and a piston 110. The cylinder 120 may be formed to be inserted through a hole formed in the rock mass. For example, it may be provided as an outer circumferential surface corresponding to the inner circumferential surface of the perforation. Here, "correspondence" means that the inner circumferential surface and the outer circumferential surface coincide, and the diameter of the cylinder 120 is formed smaller than the diameter of the perforation and can be inserted. The cylinder 120 may be provided with hydraulic pressure. A hydraulic line through which hydraulic pressure can be applied or discharged may be provided at one end of the cylinder 120. In the example shown in FIG. 1, the hydraulic line is divided into a hydraulic inlet line 121 in which hydraulic pressure is provided to the cylinder 120 and a hydraulic outlet line 122 in which hydraulic pressure is discharged from the cylinder 120. That is, whether the hydraulic lines are divided is not limited thereto, and any structure in which hydraulic pressure can be provided and discharged is satisfied.

In addition, a plurality of pistons 110 may be disposed at predetermined intervals in a longitudinal direction that is a direction inserted into the perforation. The piston 110 may protrude from the cylinder 120 by providing hydraulic pressure to the cylinder 120. It is possible to form a crack in the rock 1 by pressing the rock 1 in the protruding direction. As in this example, generally one by one at predetermined distance intervals along the extending direction of the cylinder 120, but is not limited thereto, and is the same? A plurality of pistons 110 may protrude from the outer edge of the cylinder 120 on the top.

6(a) is a view showing the piston 110 included in the halam rod 100 of FIG. 5, and FIG. 6(b) is a view showing an initial state in which the piston 110 presses the rock 1.

Referring to FIG. 6A, the piston 110 may protrude from the cylinder 120 to press the rock 1. The piston 110 may divide a portion that presses the rock 1 into each crack inducing portion. The crack induction part is divided into a first crack induction part 111 and a second crack induction part 112. The first crack induction part 111 is a part in which a crack is formed in the rock 1 by first contacting the rock 1 in order to form a crack surface C in the rock 1. In addition, the secondary crack induction part 112 may form an additional crack part 2 ′ in the rock where cracks are formed by the first crack induction part 111.

Here, the first crack induction part 111 is a structure that first comes into contact with the rock 1 by the protruding piston 110, and the piston 110 is at the foremost of the pressing direction P for pressing the rock 1 The first crack induction part may be located, and the second crack induction part 112 may be located behind the first crack induction part 111. As a preferred example, referring to FIG. 2(a), the first crack induction part 111 is formed in the foremost front of the pressing direction P of the piston 110 and may be located in the middle of the piston 110.

Although the above conditions are satisfied, the case of a cone shape may be excluded from the embodiment of the present invention. In the case of the cone shape, cracks may be caused in the rock mass 1 by a configuration corresponding to the first crack inducing part 111 located at the foremost, but the contact between the first crack inducing part 111 and the rock mass 1 is a point contact ( Since the shape is extremely close to point contact compared to line contact or surface contact), the growth direction of the crack 2 formed in the rock 1 is difficult to predict and the crack surface C cannot be formed.

Therefore, in order to control the formation direction of the crack surface (C) (to form it in a predictable direction), as in the embodiment of the present invention, the primary crack induction part 111 has a line contact (compared to a point contact or a surface contact). It can cause cracks by contacting the rock (1) through the form extremely close to the line contact). That is, the crack surface (C) can be formed within a predictable range through the crack caused by line contact. The predictable range refers to a direction in which the crack surface (C) faces and a location at which the crack surface is formed. Therefore, the crack portion 2 can be grown in a plane shape rather than in a linear shape as the pressing force increases.

On the other hand, the secondary crack induction part 112 may be formed with respective inclined surfaces extending to both sides around the first crack induction part 111. The inclined surface can be a flat or curved surface. Since the secondary crack induction part 112 is formed in an inclined surface, it gradually protrudes in the pressing direction P to induce the formation of the additional crack 2 ′ in the process of pressing the rock 1. The pressing area may vary depending on the degree of protrusion, which may vary depending on the angle of the inclined surface of the secondary crack induction part 112. The inclination angle (A) of the secondary crack inducing part, which is an angle formed between the secondary cracking parts, may be 130 degrees to 160 degrees.

Accordingly, the additional crack portion 2 ′ formed by the secondary crack inducing portion 112 may be formed at the periphery of the crack portion 2 generated by the first crack inducing portion 111. The affected part (3 in FIG. 6(b)) of the crack generated by the pressure of the piston 110 may be formed over a region including the crack part 2 and the additional crack part 2 ′.

Referring to Fig. 6(b), it shows that the affected area 3 is formed in the area including the crack 2, and the additional crack 2 is in the area of the affected area 3 excluding the crack 2 ') is formed. Here, the crack part 2 is formed by the first crack inducing part 111 and is formed extending from the point in contact with the first crack inducing part 111 toward the pressing direction. Here, the elongation formation means that the degree of cracking increases as the pressing force increases, and the increasing direction of the crack is formed toward the pressing direction (P). And, due to the increase of the crack portion 2, the area of the affected portion 3 may also be increased. Of course, in the process of increasing the crack portion 2, since the pressing force is continuously increased, the formation and extension of the additional crack portion 2'can be made.

7(a) is a diagram showing a mid-term state in which the piston of FIG. 6 presses the rock 1, and FIG. 7(b) is a diagram illustrating a late state in which the rock 1 is pressed,

Referring to Figure 7 (a), it shows that the additional crack (2') is formed. If the pressing force is applied more than from FIG. 6(b), it may be the state of FIG. 7(a). That is, if the pressing force acts more strongly after the crack portion 2 is formed, the crack portion 2 may grow and the additional crack portion 2'may be formed. Referring to FIG. 7(b), since the pressing force from FIG. 3(a) is further increased, the crack portion 2 may be grown and the additional crack portion 2'may be grown and formed.

Here, the region including the crack portion 2 and the additional crack portion 2'may be the affected portion 3. The influence part 3 may be formed in one direction from the cylinder 120. In addition, in order to perform halam, a plurality of halam rods 100 are inserted into the rock mass 1 so that the rock mass 1 positioned between the halam rods 100 disposed around may be crushed. To this end, the two hamam rods 100 disposed in the periphery may be disposed so that one of them faces each other. Accordingly, the affected part 3 may be overlapped, and the overlapped affected part 3 may be crushed and the crack surface C may be exposed. In other words, the overlapped impact portion 3 may become the crack surface C.

8 is a view showing a tunnel construction elevator 20 according to another embodiment of the present invention. In this embodiment, a description of the configuration common to the previous embodiment will be omitted.

Referring to FIG. 8, the tunnel construction lift box 20 may be located on the side where the haambong cradle 250 is performed on the tunnel of the tunnel construction lift box 20. More specifically, the plurality of halam rod holders 250 may be formed in a shape having an insertion hole through which the halam rod 100 can be inserted in a vertical direction on the side where the tunnel operation is performed. Since the Halambong cradle 250 is located on the side where the tunnel work is performed, the worker can lift the halambong 100 from the halambong cradle 250 and apply it to the work immediately. The pump cradle 25 capable of mounting a pump (not shown) that allows the halam rod 100 to perform the halam operation may be located on the opposite side of the place where the halam rod cradle 250 is located.

A hydraulic inlet line and a hydraulic outlet line (not shown) through which hydraulic pressure supplied from the pump is transmitted may be connected between the pump mounted on the pump holder 25 and the haambong 100. In this embodiment, the pressure transmission line connects the pump and the halam rod 100 along the bottom of the bottom plate 21 of the tunnel construction lift box 20 so that the hydraulic inlet line and the hydraulic outlet line do not interfere with the work. You can do it neatly in terms of aesthetics.

In order to facilitate the removal of the Halambong 100 from the Halambong cradle 250 and then mounting it back to the Halambong cradle 250, in this embodiment, the return means 260 is corresponding to each halambong 100 Can be formed. The return means 260 may be a rotating means winding the line 260a. The return means 260 may be connected to a power means such as a motor. While the user pulls out the halambong 100, the line 260a wound around the return means 260 may be released and come out of the halambong 100. And, when it is necessary to return the halambong 100 again, such as when the work is finished, the return means 260 may be driven so that the return means 260 rewinds the line 260a. Then, while the line 260a is wound, the halam rod 100 may be inserted into the halam rod holder 250 again.

In this embodiment, the shelf 28 is formed so that when the user uses the halam rod 100, the user can work in a state that spans the shelf 28, thereby reducing the user's fatigue.

Here, when the user completes the halam operation for the tunnel, it is as described above that the halambong 100 is again mounted on the halambong cradle 250 through the return means 260.

FIG. 10 is a view for explaining the withdrawal means 29 in the elevator box 20 for tunnel construction of FIG. 8.

Referring to FIG. 10, in this embodiment, a withdrawal means 29 may be formed separately from the return means 260. There may be a case in which the user's halam rod 100 is stuck in the tunnel surface while the user performs halam work using the halam rod 100, so that the halam rod 100 cannot be pulled out by the force of a person. In this case, a safety accident may occur while a person is forcibly trying to pull out the halambong (100). In order to prevent this, the lead line 29a wound around the withdrawal means 29 may be connected to the halambong 100 and the halambong 100 may be taken out from the tunnel surface by driving the withdrawal means 29. To this end, the power driving the withdrawal means 29 may be of high output.
