DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a waste carrying-out system according to the present invention will be described in detail below with reference to the drawings. In the following, when simply referred to as “upstream/downstream”, it means upstream/downstream of the muck transport within the tunnel 51 . FIG. 1 is a cross-sectional view of a tunnel 51 under construction to which the muck carrying-out system 1 of the present embodiment is applied. The waste carry-out system 1 is a system that carries waste S (rocks) generated by blasting of the face 53 of the tunnel 51 to the pit side and carries it out of the tunnel 51 . That is, the upstream side is the face 53 side, and the downstream side is the wellhead side (outside the tunnel 51). As shown in FIG. 1, the waste carrying-out system 1 includes a waste pretreatment unit 3 installed near a face 53 for crushing waste S, and a tunnel 51 connected to the downstream side of the waste pretreatment unit 3 and extending to the vicinity of the pit. a belt conveyor 5 extending therein.

The belt conveyor 5 extends in the longitudinal direction of the tunnel 51 in the vicinity of one inner wall surface of the tunnel 51 along the inner wall surface at a position of about 2 m in height, for example. The upstream end of the belt conveyor 5 is composed of a tailpiece carriage 5a. This type of belt conveyor 5 is generally called a "continuous belt conveyor", and the belt conveyor 5 can be extended sequentially according to the progress of the tunnel construction. That is, the tailpiece carriage 5a at the upstream end of the belt conveyor 5 is movable as the tunnel construction progresses (movement of the face 53). The width of the belt conveyor 5 is, for example, 750 mm, which is suitable for conveying the waste S with a size of about 250 mm. On the other hand, since the waste S generated by the blasting of the face 53 is large, for example, about 700 to 900 mm, it is necessary to crush the waste into a size suitable for transportation on the belt conveyor 5 . Therefore, the waste pretreatment unit 3 crushes the waste S on the upstream side of the belt conveyor 5 . Although the details will be described later, the waste pretreatment unit 3 is composed of two machines arranged in series such as a hopper feeder carriage 7 (mobile receiving and sending machine) and a crusher 9 (mobile crusher). ing.

Further, in the waste carrying-out system 1 , a wheel loader 15 (muck loader) is used in the vicinity of the face 53 in order to take out the waste S generated at the face 53 and load it into the waste pretreatment unit 3 . After the waste S is generated by the blasting of the face 53 , the wheel loader 15 scoops up the waste S from the face 53 with the bucket 15 a and conveys it, and throws the waste S in the bucket 15 a into the waste pretreatment section 3 . The capacity of the bucket 15a is, for example, 3 to 4 m ³ , and the wheel loader 15 reciprocates between the face 53 and the waste pretreatment section 3 about 30 to 100 times in order to transport the waste S generated by one blasting. . Here, a plurality of wheel loaders 15 may be operated together. In the waste pretreatment unit 3, the waste S is fed in the order of the hopper feeder carriage 7 and the crusher 9, and the waste S that has been crushed into a size suitable for transportation by the belt conveyor 5 and finely divided is sent to the tail piece carriage 5a of the belt conveyor 5. Ejected. Then, the waste S is conveyed to the vicinity of the well opening by the conveyor body 5 c of the belt conveyor 5 and carried out of the tunnel 51 .

The shear preprocessing unit 3 will be described with reference to FIGS. 2 and 3. FIG. FIG. 2 is a perspective view of the shear pretreatment section 3, and FIG. As described above, the waste pretreatment unit 3 includes a self-propelled mobile hopper feeder truck 7 and a self-propelled crusher 9 arranged in series on the downstream side of the hopper feeder truck 7. .

The hopper feeder carriage 7 has a hopper portion 21 (muck receiving portion) for receiving the waste S fed from the wheel loader 15 . The hopper portion 21 has a container-like shape with a predetermined vertical width, and has a bottom plate 21a forming a rectangle elongated in the upstream and downstream directions, and side wall plates 21b rising upward from the edges of the bottom plate 21a. there is The bottom plate 21a and the side wall plate 21b are made of steel so as to withstand the impact when the muck is thrown in and transported. An opening surrounded by the upper edge of the side wall plate 21b constitutes a waste receiving port 21c, which is an inlet for the waste S, and the waste receiving port 21c has a rectangular shape larger than that of the bottom plate 21a. The bottom plate 21a constitutes a vibrating plate of a vibrating feeder (not shown) built in the hopper feeder truck 7. As shown in FIG. By driving the vibrating feeder, the bottom plate 21a vibrates, and the waste S on the bottom plate 21a is fed downstream.

Further, the hopper feeder carriage 7 has a belt conveyor section 23 (upstream side of the waste conveying section) continuously provided downstream of the hopper section 21 . The belt conveyor section 23 has a conveying belt 23a extending in the upstream and downstream directions, and guide plates 23b that rise obliquely upward on both sides of the conveying belt 23a and guide the conveyance of the waste S. As shown in FIG. The conveying belt 23a and the guide plate 23b are made of steel so as to withstand impacts and the like during conveying of the waste. The conveying belt 23a is inclined so as to become higher from the upstream side toward the downstream side. That is, the conveying path of the waste S on the conveying belt 23a is uphill. An adjusting mechanism (not shown) such as a hydraulic cylinder may be provided to adjust the inclination angle of the conveying belt 23a. The conveyor belt 23a is adjusted, for example, so as to be inclined at about 20° with respect to the horizontal. In addition, the inclination angle of the conveying belt 23a may be set as large as possible within a range in which the waste S can be conveyed. The waste S that has reached the downstream end of the bottom plate 21a of the hopper portion 21 is transported downstream while being raised by the transport belt 23a. After that, the waste S is transferred from the downstream end of the conveyor belt 23a to the crusher 9, which will be described later.

Furthermore, the hopper feeder carriage 7 is provided with crawlers 27 . The crawler 27 is provided at a position below the hopper portion 21 , and functions as a support portion that supports the weight of the hopper feeder carriage 7 while allowing the hopper feeder carriage 7 to move by itself.

The crusher 9 has an input belt conveyor section 31 (on the downstream side of the waste conveying section), a waste crushing section 33 , and a trailing belt conveyor section 35 . The input belt conveyor portion 31 includes a conveyor belt 31a that is inclined at approximately the same angle as the conveyor belt 23a of the hopper feeder carriage 7 and extends in the upstream and downstream directions, and a skew S that rises outward and obliquely upward on both sides of the conveyor belt 31a. and a guide plate 31b for guiding the conveyance of the . The conveying belt 31a and the guide plate 31b are made of steel so as to withstand impacts and the like during conveying of the waste. The upstream end of the conveying belt 31a is arranged so as to overlap the downstream end of the conveying belt 23a and slip under the conveying belt 23a. Also, the upstream end of the guide plate 31b is arranged outside the downstream end of the guide plate 23b. Therefore, the waste S dropped from the downstream end of the conveying belt 23a is continuously placed on the conveying belt 31a and conveyed downstream while ascending. Then, the waste S that has reached the downstream end of the conveying belt 31 a is thrown into the waste crusher 33 . The upstream end portion of the input belt conveyor portion 31 may be detachably fixed to the downstream end portion of the belt conveyor portion 23 by a predetermined fixing means.

The waste crusher 33 crushes the relatively large waste S introduced from the inlet 33 d located at the upper end, and discharges it downward as fine waste S suitable for transportation on the belt conveyor 5 . The waste crusher 33 has a fixed blade 33a and a movable blade 33b facing each other in the horizontal direction, and is a so-called "jaw crusher" type crusher. The gap between the fixed blade 33a and the movable blade 33b is narrowed downward, and this gap is a crushing space 33c into which the waste S is introduced. The waste S from the conveying belt 31a is introduced into the crushing space 33c through an inlet 33d located above the crushing space 33c.

Then, when the movable blade 33b is driven by a predetermined driving source (not shown), the waste S is crushed and crushed by the fixed blade 33a and the movable blade 33b, and is moved downward in the crushing space 33c by gravity. being sent. In this manner, the waste S is crushed to a size suitable for transportation on the belt conveyor 5 . The waste S crushed by the waste crushing section 33 is discharged from the lower end of the crushing space 33 c and transferred to the upstream end of the trailing belt conveyor section 35 . A known jaw crusher type crushing unit may be employed as the waste crushing unit 33, so further detailed description will be omitted. In the crushing unit of the jaw crusher type, a predetermined height difference is required between the inlet and the outlet for the waste S.

The post-feeding belt conveyor section 35 extends obliquely from a position below the crushing space 33c so as to become higher toward the downstream side. The downstream end of the post-feeding belt conveyor section 35 is located above the introduction conveyor 5b (FIG. 1) of the tailpiece carriage 5a of the belt conveyor 5. As shown in FIG. The waste S transferred from the waste crushing section 33 to the trailing belt conveyor section 35 is conveyed by the trailing belt conveyor section 35 while ascending above the tailpiece carriage 5a. Then, the waste S falls off from the downstream end of the trailing belt conveyor 35, is transferred to the introduction conveyor 5b of the tailpiece carriage 5a, and is conveyed by the belt conveyor 5 to the vicinity of the pit.

Furthermore, the crusher 9 is equipped with crawlers 37 . The crawler 37 is provided at a position below the muck crushing section 33 and functions as a supporting section for supporting the weight of the crusher 9 as well as making the crusher 9 self-propelled. The hopper feeder carriage 7 and the crusher 9 are independently movable.

Further, the hopper feeder carriage 7 and the crusher 9 in the waste pretreatment section 3 may be arranged so that the waste conveying direction is continuous in a straight line parallel to the longitudinal direction of the tunnel 51 when viewed from above. Alternatively, the hopper feeder carriage 7 and crusher 9 in the shear pretreatment unit 3 may be arranged as shown in the plan view of FIG. 4, for example. The hopper feeder carriage 7 of the shear pretreatment unit 3 in FIG. The hopper portion 21 of the hopper feeder carriage 7 is located closer to the inner side of the tunnel 51 than the downstream end of the belt conveyor portion 23 .

That is, in the arrangement of FIG. 4 , the longitudinal direction of the vehicle of the hopper feeder truck 7 is inclined with respect to the longitudinal direction of the tunnel 51 in plan view, and the conveying direction of the waste S in the hopper feeder truck 7 is the longitudinal direction of the tunnel 51 . It is slanted with respect to the direction. The angle α of this inclination is, for example, about 10°. On the other hand, the conveying direction of the waste S in the crusher 9 is substantially parallel to the longitudinal direction of the tunnel 51 . In this case, the hopper feeder carriage 7 and the crusher 9 are arranged so as to be bent in a doglegged shape when the waste pretreatment unit 3 is viewed from above.

The effects obtained by the arrangement of FIG. 4 are as follows. Here, it is assumed that a front dump type wheel loader is used as the wheel loader 15, and the operation of the wheel loader 15 throwing the waste S into the hopper portion 21 is considered. In this case, as shown in FIG. 4, the wheel loader 15 moves the waste S in the bucket 15a to the hopper portion in front of the vehicle in a state in which the longitudinal direction of the vehicle is perpendicular to the longitudinal direction of the hopper portion 21. 21 is preferred. Therefore, if the longitudinal direction of the hopper feeder carriage 7 is parallel to the longitudinal direction of the tunnel 51 , the wheel loader 15 must face the longitudinal direction of the vehicle in a direction forming 90° with respect to the longitudinal direction of the tunnel 51 .

On the other hand, if the angle α is, for example, 10° as shown in FIG. . As a result, the arrangement of FIG. 4 requires less steering of the wheel loader 15 reciprocating between the face 53 and the hopper portion 21 than if the hopper feeder carriage 7 and crusher 9 were arranged in a straight line. Operations can be kept small. If the angle α is too large, the installation space for the hopper feeder carriage 7 becomes large in the width direction of the tunnel 51, which is not preferable. For example, the angle α is preferably 5-15°.

Next, the effects of the waste carrying-out system 1 will be described. As described above, the waste S generated at the face 53 is crushed by the waste crusher 33 of the crusher 9 before being conveyed by the belt conveyor 5 . Since the waste crusher 33 needs to crush the waste S of about 70 to 90 mm as described above, it is inevitably large to some extent. The waste crushing unit 33 is a jaw crusher type crushing unit, in which waste S is introduced from an upper inlet 33d and the crushed waste S is discharged downward. Therefore, the inlet 33d of the waste crusher 33 is located at a relatively high position (for example, about 4 m in height).

In the waste carrying-out system 1, the waste S is conveyed while being lifted from the bottom of the hopper section 21 to the introduction port 33d by the belt conveyor section 23 and the introduction belt conveyor section 31. As shown in FIG. Therefore, regardless of the height of the inlet 33d of the waste crushing section 33, the bottom of the hopper section 21 can be arranged at a relatively low position. The waste receiving port 21c of the hopper portion 21 can be arranged at a position lower than the input port 33d. For example, the inclination angle of the conveying belts 23a and 31a of the belt conveyer section 23 and the belt conveying section 31 is set to 20°, and the waste receiving port 21c can be arranged at a height of about 2 m from the bottom of the tunnel.

A space between the bottom plate 21a at the bottom of the hopper portion 21 and the waste receiving port 21c is a retention portion in which the waste S introduced from the wheel loader 15 is temporarily retained. Therefore, in general, it is preferable to increase the height difference between the waste receiving port 21c and the bottom plate 21a in order to increase the retention amount of the waste S in the hopper portion 21 . However, if the position of the waste receiving port 21c is raised, the space between the waste receiving port 21c and the ceiling of the tunnel 51 becomes narrower. Handling of 15a becomes difficult, and loading becomes difficult.

Here, FIG. 5 is a front view showing a state in which the wheel loader 15 throws the waste S into the hopper portion 21. As shown in FIG. In the waste carrying-out system 1, by arranging the waste receiving port 21c at a relatively low position as described above, the space A between the waste receiving port 21c and the ceiling of the tunnel 51 is widened as shown in FIG. can be secured. Then, when throwing the waste S into the hopper portion 21, the ceiling of the tunnel 51 is unlikely to be an obstacle, and the wheel loader 15 can handle the bucket 15a in the wide space A, so that the bucket 15a has a relatively large capacity. 15a can be used. By increasing the capacity of the bucket 15a, the ability of the wheel loader 15 to convey the waste S is improved, and the ability to carry out the waste S as a whole of the waste carrying-out system 1 is improved.

In this embodiment, a front dump type wheel loader is employed as the wheel loader 15 . Here, as shown in FIG. 6, it is assumed that a side dump type wheel loader 16 is used instead of the front dump type wheel loader 15 . In the side-dump type wheel loader 16, the bucket 16a is routed at a position closer to the center in the width direction of the tunnel 51 when throwing the waste S into the hopper portion 21 compared to the front-dump type. Further, according to the side dump type wheel loader 16, as shown in FIG. 6, the bucket 16a is tilted so as to raise the side near the center of the tunnel 51 in the width direction.

Since the ceiling of the tunnel 51 is higher toward the center in the width direction of the tunnel 51, when the side dump type wheel loader 16 is adopted, the ceiling of the tunnel 51 may originally become an obstacle to handling of the bucket 16a. is low. Therefore, the destination of the waste S (for example, the waste receiving port 21c) by the wheel loader 16 may be located at a relatively high position. However, since the bucket 16a of the side dump type wheel loader 16 generally dumps the contents to the side, it has a structure without side walls, so that the shear S during transportation is dumped on the side of the bucket 16a. There is a drawback that it is easy to fall off.

On the other hand, in the waste carrying-out system 1 of the present embodiment, by lowering the waste receiving port 21c and securing a wide space A above the waste receiving port 21c, when the front dump type wheel loader 15 is adopted, Even so, it facilitates handling of the large-capacity bucket 15a. Further, by adopting the front dump type wheel loader 15, it is possible to avoid the problem that the waste S during transportation tends to fall off the bucket 15a. Therefore, by adopting the front dumping method, the amount of the scrap S that can be transported by the wheel loader 15 at one time is increased compared to the side dumping method, and the carrying-out capability of the scrap carrying-out system 1 as a whole is also improved. do.

The waste loader for loading the waste S into the hopper portion 21 is not limited to the wheel loader, and various machines having a bucket for holding the waste S, such as an excavator, can also be employed. can.

The present invention can be embodied in various forms with various modifications and improvements based on the knowledge of those skilled in the art, including the embodiment described above. Moreover, it is also possible to configure the following modifications using the technical matters described in the above-described embodiments. You may use it, combining the structure of each embodiment etc. suitably.

(Modification)
A modification of the shear preprocessing unit 3 will be described. In the waste carrying-out system 1, a waste pre-processing unit 91 shown in FIG. 7A can be used in place of the waste pre-processing unit 3 described above. The shear pretreatment unit 91 includes a hopper feeder truck 7 and a crusher 9 . In the crusher 9 of the waste pretreatment section 91, instead of the upwardly inclined introduction belt conveyor section 31, the introduction belt conveyor section conveys the waste S in a substantially horizontal direction and throws it into the introduction opening 33d of the waste crushing section 33. 32 are provided. The waste S conveyed while ascending by the belt conveyor portion 23 of the hopper feeder carriage 7 is transferred to the belt conveyor portion 32 for input, moves horizontally, and is input to the input port 33d.

In this shear pretreatment section 91, the size of the belt conveyor section 23 that cantilevers from the main body of the hopper feeder truck 7 tends to be longer than that in the shear pretreatment section 3 described above. There is also a tendency for the main body of the camera to become larger. The above-described shear pretreatment section 3 is preferable to the shear pretreatment section 91 of this modified example in that it is possible to avoid such an increase in the size of the main body of the hopper feeder truck 7 . In the shear pre-processing unit 91, the same or equivalent constituent elements as those of the slip pre-processing unit 3 described above are given the same reference numerals, and overlapping descriptions are omitted.

(Other modifications)
Another modification of the shear preprocessing unit 3 will be described. In the waste carrying-out system 1, a compound machine 93 shown in FIG. 7(b) can be used in place of the aforementioned waste pretreatment unit 3. The compound machine 93 integrally includes the functions of the hopper feeder carriage 7 and the crusher 9 in its main body. Specifically, the multi-function machine 93 has a hopper section 21 , a belt conveyor section 23 , a waste crushing section 33 , and a trailing belt conveyor section 35 .

Further, in the multifunction machine 93, the input belt conveyor section 31 and the input belt conveyor section 32 are not provided. The downstream end of the belt conveyor section 23 is integrally connected to the waste crushing section 33, and the waste S that has reached the downstream end of the belt conveyor section 23 is directly thrown into the inlet 33d of the waste crushing section 33. It is designed to be Further, although the crawler 37 is provided below the waste crushing section 33 , a sleigh-like sliding leg section 28 is provided below the hopper section 21 instead of the crawler 27 . The multi-function machine 93 is self-propelled by the drive of the crawler 37, and at this time, following the movement of the crawler 37, the sliding legs 28 slide on the ground. The sliding leg 28 functions as a support that supports part of the weight of the composite machine 93 . In the multi-function machine 93, the same reference numerals are given to the same or equivalent components as those of the shear pretreatment unit 3 described above, and redundant explanations will be omitted.
