Description

  The present invention relates to a tail piece carriage on which a tail piece portion of a continuous belt conveyor capable of extending a belt is placed, a moving method thereof, and a method of extending a continuous belt conveyor.

  2. Description of the Related Art Conventionally, a continuous belt conveyor has been used as one of discharge facilities for discharging gaps generated by excavation of natural ground in tunnel construction sites. This continuous belt conveyor is installed near the face in the tunnel, and is composed of a tail piece section for folding the belt and a cassette section for storing the belt by folding it back and forth, according to the tunnel excavation progress. While moving the tail piece part in the advancing direction, the belt is extended from the cassette part by extending the belt.

  As a general method for moving the tail piece portion in the traveling direction, there is a method in which a rail is laid in a tunnel and a tail piece carriage on which the tail piece portion is placed travels on the rail.

  Further, for example, Patent Document 1 discloses a tailpiece truck equipped with an endless track car, and by moving the tailpiece truck in the traveling direction by driving the endless truck according to the excavation progress of the tunnel. The tail piece is moved.

However, the above-described method for moving the tailpiece carriage has the following problems.
(1) When the tailpiece carriage is moved in the traveling direction, it is moved with a force larger than the tension acting on the belt of the continuous belt conveyor. The capital investment cost becomes high.
(2) To avoid an increase in the size of the traveling device, release the belt tension before moving the tailpiece carriage, and after moving the tailpiece carriage, introduce the tension to the belt and perform the running-in operation. There must be. However, since this work takes about half a day, it is difficult to frequently move the tailpiece carriage.
(3) Since tension release / introduction and break-in operation takes time and labor, it cannot be performed in parallel with other work incidental to tunnel excavation. Therefore, when moving the tailpiece carriage, all other work in the tunnel must be stopped.

  Accordingly, the present invention has been made in view of the above problems, and provides a tail piece cart that can be efficiently moved by a small number of people, a moving method thereof, and a method of extending a continuous belt conveyor. With the goal.

In order to achieve the above object, the present invention is a tail piece carriage on which a tail piece portion of a continuous belt conveyor is placed,
A stand for mounting the tailpiece part;
A first telescopic means connected to the gantry and capable of raising and lowering the gantry;
A support base for supporting the frame so as to be relatively movable in a direction in which the continuous belt conveyor is extended;

  According to the present invention, the gantry can be supported by extending the first expansion / contraction means and grounding its lower end to the ground. Further, by extending the second expansion / contraction means and grounding the lower end thereof to the ground, the support base can be supported together with the endless track vehicle.

Then, the first expansion / contraction means is contracted until its lower end is separated from the ground, and the second expansion / contraction means is expanded until its lower end is in contact with the ground. When the drive device is driven in a state where it is supported, the gantry can be moved in the extending direction of the continuous belt conveyor with respect to the support table. Thereby, the tail piece carriage can be moved in the extending direction of the continuous belt conveyor. At that time, by driving the driving device with a force larger than the tension acting on the belt of the continuous belt conveyor, the tail piece portion can be moved while the tension is applied to the belt, and the belt can be extended. . At this time, the second telescopic means is grounded to the ground together with the endless track vehicle to support the support base, so that the tail piece portion can be moved against the belt tension. Further, the height of the tail piece after the belt extension work is made the same as that before the extension work by adjusting the height of the tail piece part by expanding and contracting the first extension means and the second extension means. Can be maintained. That is, the extension work can be performed in a state close to an operating state in which a tension is applied to the belt.
Accordingly, it is not necessary to release and introduce the belt tension that has been conventionally performed before and after the extension of the continuous belt conveyor, and the running-in time can be shortened.

  Further, the second expansion / contraction means is contracted until its lower end is separated from the ground, and the first expansion / contraction means is extended until the lower end is in contact with the ground, and the gantry is supported only by the first expansion / contraction means. Thus, by driving the driving device, the support base and the endless track vehicle can be moved in the extending direction of the continuous belt conveyor with respect to the gantry. Thereby, the tail piece carriage can be moved in the extending direction of the continuous belt conveyor.

  Then, by using the first expansion / contraction means, the second expansion / contraction means, the drive device, and the endless track vehicle, it is possible to efficiently perform the extension operation of the continuous belt conveyor and the movement operation of the tailpiece carriage with a small number of people. Thereby, since another worker can perform another work, the construction period can be shortened.

In addition, by running the endless track vehicle, the tailpiece portion can be moved in the width direction of the tunnel, which is an orthogonal direction orthogonal to the direction in which the continuous belt conveyor is extended. Moreover, the direction of the tailpiece portion can be changed by changing the direction of the endless track vehicle. Therefore, the tailpiece carriage of the present invention can be applied to a tunnel having a curve.
Furthermore, by using the endless track car not only for the movement of the tailpiece carriage in the traveling direction but only for the movement in the width direction or the change of the direction, a small and inexpensive one can be used.

Moreover, in this invention, if the said drive device is provided with the jack which has a pressure gauge, it can extend a continuous belt conveyor by fixed pressure, confirming the magnitude | size of a pressure.
Furthermore, by using a jack, even if there is unevenness on the ground, the belt can be extended in the traveling direction without being affected, and without damaging the belt while tension is applied to the belt. At that time, the gantry and the support base can be accurately moved in a desired direction by a predetermined distance.

  Moreover, in this invention, it is good also as providing the measuring device for measuring the height of the said tailpiece part.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view of a tailpiece cart 1 according to the present embodiment.
As shown in FIG. 1, the tailpiece carriage 1 includes a gantry 4 for placing the tailpiece portion 3 of the continuous belt conveyor 2, a first telescopic means 5 for supporting the gantry 4, and the gantry 4. The pedestal 4 is moved in a direction in which the continuous belt conveyor 2 is extended (hereinafter referred to as a traveling direction), a support base 6 for supporting the support base 6 so as to be relatively movable, a second expansion / contraction means 7 for supporting the support base 6. Drive device 8, a self-propelled endless track vehicle 9 on which the support base 6 is mounted, and a measuring instrument 10 for measuring the height of the tail piece portion 3.

  In addition, although many various facilities are installed around the continuous belt conveyor 2, since it is unnecessary for description of this invention, illustration is abbreviate | omitted.

  The gantry 4 is composed of two steel plates 4b and 4c arranged above and below with a predetermined gap 4a, and the tail piece portion 3 is installed on the upper steel plate 4b. A support base 6 made of a steel plate is provided in the gap 4a so as to be slidable with respect to the steel plates 4b and 4c.

  The first expansion / contraction means 5 is an outrigger that can be expanded and contracted by hydraulic pressure, and a plurality of first expansion / contraction means 5 are attached to the gantry 4. The gantry 4 can be supported by extending the first expansion / contraction means 5 and grounding its lower end to the ground 11.

  Similarly to the first expansion / contraction means 5, the second expansion / contraction means 7 is also an outrigger, and a plurality of second expansion / contraction means 7 are attached to the support base 6. The support base 6 can be supported together with the endless track vehicle 9 by extending the second expansion / contraction means 7 and grounding its lower end to the ground 11.

  Further, each of the first expansion / contraction means 5 and the second expansion / contraction means 7 can be expanded and contracted independently. For this reason, even if there is unevenness on the ground 11, by adjusting the length of each of the first extension means 5 and each of the second extension means 7, the gantry 4 is leveled and the tailpiece portion 3 is placed in advance. It can be accurately installed at a predetermined height determined by design or the like. That is, the height of the continuous belt conveyor 2 can always be kept constant.

  The driving device 8 is disposed in the gap 4 a, and one end thereof is connected to the front end portion in the moving direction of the gantry 4 and the other end is connected to the front end portion in the moving direction of the support base 6. In the present embodiment, for example, a jack provided with a pressure gauge is used as the driving device 8.

  When the tailpiece carriage 1 is moved in the traveling direction, first, the second expansion / contraction means 7 is expanded until the lower end thereof contacts the ground 11 and the first expansion / contraction means 5 is contracted. In the state where 5 is separated from the ground surface 11, the support base 6 is supported by the second telescopic means 7 together with the endless track 9. Then, by extending the driving device 8, the gantry 4 is moved in the traveling direction with respect to the support pedestal 6. Extending the belt by moving the tail piece part 3 with the tension applied to the belt by making the extension force of the driving device 8 larger than the tension acting on the belt of the continuous belt conveyor 2. Can do. At this time, together with the endless track 9, the lower base of the second expansion / contraction means 7 is grounded to the ground 11 to support the support base 6, so that the tail piece portion 3 can be moved against the belt tension. it can.

  Next, the first extension / contraction means 5 is extended until the second extension / contraction means 7 and the endless track 9 are separated from the ground 11, and the gantry 4 is supported only by the first extension / contraction means 5. The support base 6 is moved in the traveling direction with respect to the gantry 4 by contracting.

  Then, the tail piece carriage 1 is moved by repeating the movement of the gantry 4 and the support base 6 alternately in the traveling direction.

  The pressure at which the driving device 8 is extended is determined according to the tension of the belt of the continuous belt conveyor 2, the weight of the gantry 4 and the support pedestal 6, and the like. When the tension of the belt is large and the pressure when the driving device 8 is extended becomes excessive, a plurality of driving devices 8 may be used.

  In the present embodiment, a crawler that can be driven by hydraulic pressure is used as the endless track vehicle 9. By using the endless track 9, the tailpiece carriage 1 can be moved to the tunnel wall side or the direction can be changed when passing through a curved portion of the tunnel, as will be described later.

  The measuring device 10 is provided on the side surface of the tail piece portion 3 and measures the height from a preset reference point.

  The tail piece cart 1 having the above-described configuration supports the gantry 4 and the support base 6 with the first telescopic means and the second telescopic means, respectively, and the continuous belt with the tail piece portion 3 installed at a predetermined height. The conveyor 2 is operated to carry out excavation earth and sand.

  Next, a method for extending the continuous belt conveyor 2 and a method for moving the tailpiece carriage 1 using the tailpiece carriage 1 having the above-described configuration will be described in accordance with work procedures.

  2-7 is a figure which shows the process of moving the tailpiece trolley | bogie 1 to an advancing direction while extending the continuous belt conveyor 2. FIG.

  First, as shown in FIG. 2, the first expansion / contraction means 5 is contracted until the lower end of the first expansion / contraction means 5 is separated from the ground 11, and together with the endless track 9, the second expansion / contraction means 7 supports the support base 6. Is supported (support stage support process).

  Next, as shown in FIG. 3, the driving device 8 is extended with a force larger than the tension acting on the belt of the continuous belt conveyor 2, so that the gantry 4 moves in the direction of travel with respect to the support pedestal 6, and the belt is tensioned. It is moved in the acted state (base feed process). That is, the continuous belt conveyor 2 is extended by advancing the tail piece portion 3 placed on the gantry 4 while the belt is being rotated without loosening the belt tension. At this time, the operation is performed while confirming the pressure of the driving device 8 with a pressure gauge so that the operating pressure of the driving device 8 does not exceed a preset specified value.

  In addition, the belt which extended the continuous belt conveyor 2 is drawn | fed out from the cassette part (not shown) for belt accommodation installed in the wellhead side.

  Next, as shown in FIG. 4, the first telescopic means 5 is extended to support the gantry 4 until the second telescopic means 7 and the endless track 9 are separated from the ground 11 (the gantry supporting step). At this time, the second expansion / contraction means 7 may be contracted.

  Next, as shown in FIG. 5, the drive device 8 is contracted to move the support base 6 and the endless track 9 in the traveling direction with respect to the base 4 (support base feed process). The distance by which the support base 6 is advanced is the same as the distance by which the base 4 is advanced in the above-mentioned base feed process.

  Next, as shown in FIG. 6, the first telescopic means 5 is contracted until the endless track 9 contacts the ground 11, and the gantry 4 is supported by the first telescopic means 5. The expansion / contraction means 7 is extended until the lower end of the expansion / contraction means 7 comes in contact with the ground 11, and the support base 6 is supported by the second expansion / contraction means 7 together with the endless track 9 (cart support process).

  At this time, since there may be irregularities on the ground surface 11 with which the lower end of the second expansion / contraction means 7 comes into contact, the first expansion / contraction means 5 and the second expansion / contraction means 5 and the second expansion / contraction means 5 have a predetermined height. The expansion / contraction amount of the expansion / contraction means 7 is adjusted. Specifically, the height of the tail piece part 3 is measured by the measuring instrument 10 to check whether the tail piece part 3 exists at a predetermined height set in advance. When the height from the reference point to the tail piece part 3 is measured and the tail piece part 3 is higher than a predetermined height, the first extension means 5 or the second extension means 7 is contracted. Then, the height of the tail piece part 3 is adjusted to a predetermined height. On the other hand, when the tail piece part 3 is lower than the predetermined height, the first extension means 5 or the second extension means 7 is extended to adjust the height of the tail piece part 3 to the predetermined height.

  Thereafter, by attaching an extension member to a portion where the belt is extended, the continuous belt conveyor 2 can be operated.

In addition, when it is necessary to change the direction of the tail piece portion 3, for example, when passing through a curved portion of the tunnel, or when adjusting the direction of the continuous belt conveyor 2 even in a linear tunnel, the endless track The vehicle 9 is driven to change its direction (direction correction step).
Further, when the tailpiece carriage 1 passes through the curved portion of the tunnel, the tailpiece carriage 1 is moved along the curve in the width direction of the tunnel, specifically, in the direction approaching the wall or away from the wall. If necessary, as shown by the arrow in FIG. 7, the endless track 9 is moved backward to move to a desired position.

  If the tunnel is straight and there is no need to move the tailpiece portion 3 in the width direction of the tunnel or change the direction, the direction correcting step may be omitted.

  After the tail piece 3 is moved to the wall side or after changing the direction, the first expansion / contraction means 5 and the second expansion / contraction means 7 are extended, and the gantry 4 is supported by the first expansion / contraction means 5. The support belt 6 is supported by the second telescopic means 7 together with the endless track 9 (see FIG. 6), so that the continuous belt conveyor 2 can be operated.

  Through the above steps, the continuous belt conveyor 2 can be extended and the tailpiece carriage 1 can be moved.

  According to the tailpiece carriage 1 in the present embodiment described above, the gantry 4 can be supported by extending the first telescopic means 5 and grounding the lower end thereof to the ground 11. Further, the support base 6 can be supported together with the endless track 9 by extending the second expansion / contraction means 7 and grounding the lower end thereof to the ground 11.

  The tail piece portion 3 can be moved in the traveling direction by extending the driving device 8 in a state where the support base 6 is supported by the second telescopic means 7 together with the endless track 9. Thereby, the tailpiece carriage 1 can be moved in the traveling direction. At that time, by extending the driving device 8 with a force larger than the tension acting on the belt of the continuous belt conveyor 2, the tail piece part 3 is moved while the tension is applied to the belt, thereby extending the belt. can do. At this time, the second telescopic means 7 is grounded to the ground 11 together with the endless track 9, and the support base 6 is supported, so that the tailpiece portion 3 can be moved against the belt tension.

  The first extension / contraction means 5 is extended until the second extension / contraction means 7 and the endless track 9 are separated from the ground 11, and the gantry 4 is supported only by the first extension / contraction means 5. By contracting, the support base 6 and the endless track 9 can be moved in the traveling direction. Thereby, the tailpiece carriage 1 can be moved in the traveling direction.

  In addition, since the continuous belt conveyor 2 is extended not by movement by the endless track 9 but by extension of the driving device 8, even if the ground surface 11 is uneven, it is not affected by this, and tension is applied to the belt. The belt can be extended in the traveling direction without damaging the belt. At that time, the gantry 4 and the support table 6 can be accurately moved by a predetermined distance in a desired direction.

Furthermore, while measuring the height of the tail piece part 3 with the measuring instrument 10, by adjusting the lengths of the first expansion means 5 and the second expansion means 7, the gantry 4 is made horizontal, The tail piece part 3 after extension of the continuous belt conveyor 2 can be made the same height as before extension.
Therefore, there is no need to perform the work of releasing the belt tension before the extension or the work of introducing the belt tension after the extension. Moreover, the running-in time can be shortened.

Moreover, by running the endless track vehicle 9, the tail piece part 3 can be moved in the width direction, or the direction of the tail piece part 3 can be changed. Thereby, the tailpiece carriage 1 of the present invention can be applied to a tunnel having a curve.
The endless track 9 is not used for the movement of the tailpiece carriage 1 in the traveling direction, but only for the movement in the width direction or the change of the direction, so that a small and inexpensive one can be used.

  Further, by using the first expansion / contraction means 5, the second expansion / contraction means 7, the driving device 8, the endless track car 9 and the like, the extension of the continuous belt conveyor 2 and the movement of the tailpiece carriage 1 can be efficiently performed with a small number of people. be able to. Thereby, since another worker can perform another work, the construction period can be shortened.

  Further, since the tailpiece carriage 1 can be efficiently moved by a small number of people, the tailpiece carriage 1 can be moved frequently. As a result, the distance from the face to the tailpiece carriage 1 is shortened, so that the slipping work can be performed efficiently.

  In addition, if it is assumed that at least one of the support base support process, the base feed process, the base support process, the support base feed process, the cart support process, and the direction correction process is performed in parallel with other work incidental to tunnel excavation The process can be greatly shortened.
