[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention is used, for example, in various tunnel constructions for subways, telephone lines, power lines, water and sewerage, etc. The present invention relates to a segment transfer device in a tunnel suitable for safe transfer.

[0002]

[Prior art]

 Conventionally, in various tunnel constructions, while excavating the ground with an excavator, concrete segments such as short cylinders divided appropriately along the circumferential direction are sequentially connected along the inner wall surface of the excavation hole. , So that we can build a tunnel that can withstand considerable pressure.

When transporting the segment to the excavated portion at the tip of the tunnel, a traveling body is movably mounted on a traveling rail arranged in the tunnel, a chain block is mounted on the traveling body, and further, a drum block is installed. The wire that is unwound and unwound by rotation is wrapped around the running body, and by unwinding and rewinding this wire, the running body is moved along the running rail, and the segment hung on the chain block of the running body is removed. I try to move it.

[0004]

[Problems to be solved by the device]

 However, in the conventional segment transportation means, the traveling rail installed inside the tunnel must be slightly inclined so that the tip of the tunnel faces downwards. was there. Moreover, in a relatively narrow tunnel, when the wire is unwound from the drum for a long time, the wire itself tends to be a hindrance to the work. In addition, when excavation of the tunnel progresses to some extent, the tip of the tunnel has to be moved to the crucible at the position where the drum is attached, which is a problem in terms of workability and work efficiency. In particular, since there is an excavator at the tip of the tunnel and the work space is quite small, a relatively compact transfer device is desired.

[0016]

[Effect of device]

 Therefore, the segment transfer device S according to claim 1 is a transfer device for transferring the segment 30 which is a tunnel constituent member to a tunnel tip portion in the tunnel construction, and the segment transfer device is arranged above the tunnel. A rail 1, a self-propelled body 5 mounted on the traveling rail 1 and movable along the traveling rail 1, and a chain block mounted on the traveling rail 1 and movable along the traveling rail 1. And a roller chain 3 is provided on the lower surface of the traveling rail 1 and a sprocket 11 that meshes with the roller chain 3 is provided on the self-propelled body 5 to drive and rotate the sprocket 11. Then, the self-propelled body 5 is configured to move along the traveling rail 1, and the chain block traveling body 20 is a chain blower capable of suspending the segment 30. Since the chain block traveling body 20, which is attached to the self-propelled body 5 and has the segment 30 suspended therein, is configured to move along the traveling rail 1 together with the self-propelled body 5, for example, In the construction of various tunnels for subways, telephone lines, power lines, water and sewerage, etc., it becomes possible to reliably and safely transport the concrete segments 30 and the like, which are quite heavy, to the excavated portion at the tip of the tunnel. Further, since the vehicle is moved by the self-propelled body 5, the traveling rail 1 can be securely moved along the traveling rail 1 without having to slightly incline the traveling rail 1 so that the tunnel tip faces downward like the conventional segment transfer device S. You will be able to move to. Further, since the segment transfer device S itself can be configured compactly, the work space in the tunnel is not narrowed, and the segment transfer device S does not interfere in a relatively narrow tunnel. Therefore, the tunnel can be used effectively. In particular, although the excavator is arranged at the center of the tip of the tunnel, the segment 30 can be transported without disturbing the excavation work by the excavator. Moreover, the structure of the segment transfer device S is relatively simple, easy to handle, has excellent strength and durability, is hard to break down, is suitable for mass production, can be provided at a relatively low cost, and is highly economical.

Further, the roller chain 3 is arranged on the lower surface of the traveling rail 1, and the sprocket 11 that meshes with the roller chain 3 is provided on the self-propelled body 5 so that the sprocket 11 can be driven and rotated. Since the body 5 is configured to move along the traveling rail 1, for example, when the excavation work progresses and the excavation position and the transportation position of the segment 30 advance to some extent, the extension of the traveling rail 1 and the traveling rail 1 The extension of the roller chain 3 fixed to the above allows the self-propelled body 5 and the chain block traveling body 20 to move to the end of the tunnel, so that the segment 30 can be easily transported further forward. At the same time, the workability and work efficiency of the transfer work will be greatly improved.

In addition, the chain block traveling body 20 is mounted with the chain block 25 capable of suspending the segment 30 and is connected to the self-propelled body 5 to suspend the segment 30. Since the body 20 is configured to move along the traveling rail 1 together with the self-propelled body 5, it becomes possible for the chain block traveling body 20 alone to receive the suspension load of the segment 30, which is a considerable weight. The load on the self-propelled body 5 is reduced, and the self-propelled body 5 is less likely to be damaged, resulting in excellent durability.

Further, the segment transfer device S according to claim 2 is a transfer device for transferring the segment 30 which is a tunnel constituent member to a tunnel tip part in tunnel construction, and is arranged above the tunnel. A pair of parallel traveling rails 1 and a pair of self-propelled bodies 5 mounted on the traveling rails 1 and movable along the traveling rails 1 and mounted on the traveling rails 1 respectively. , A pair of chain block traveling bodies 20 movable along the traveling rails 1, the roller chains 3 are respectively disposed on the lower surfaces of the traveling rails 1, and the sprockets 11 meshing with the roller chains 3 are provided. Each self-propelled body 5 is provided, and the sprocket 11 is driven and rotated so that the self-propelled body 5 moves along the traveling rail 1. A chain block 25 capable of suspending the segment 30 via a segment suspension jig 31 is mounted on the traveling body 20, and the traveling body 20 is connected to the self-propelled body 5 for suspending the segment 30. Since the traveling body 20 is configured to move along with the traveling rail 1 together with the self-propelled body 5, the suspension load of the segment 30 having a considerable weight is applied to the pair of chain block traveling bodies 20 and the pair of traveling rails 1. As a result, the heavier segment 30 can be transported, and at the same time, the segment transport device S can be expected to be more reliable, more stable, and safer. In particular, the suspension balance of the segment 30 during transportation is improved, and extremely safe transportation work becomes possible.
