Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arch rebar carrier truck for transporting an arch rebar for secondary lining of a shield tunnel to a rebar assembly carriage.

[0002]

2. Description of the Related Art As shown in FIG.
The secondary lining C of the segment ring R is usually reinforced by the arch rebar S near the inner and outer circumferences.

Conventionally, the arch rebar S is transported as follows.

That is, as shown in FIG. 6, the rebar carrier A moving on the rail r is lowered by the chain block b and manually carried to the rebar assembly carrier B on the rail r by human power. Alternatively, as shown in FIG. 7, the reinforcing bar carrier A was directly transferred to the reinforcing bar assembly carrier B using the plain trolley P.

[0005]

In the former case described above,
In the latter case, the reinforcing bar S is caught on the segment ring R when the reinforcing bar S is transported by the plain trolley P in the latter case.

Further, in both cases, since the working height in the tunnel T is low and the hanging allowance is small, there is a problem that the lifting work is dangerous.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an arch reinforcing bar conveying device capable of easily and safely transferring an arch reinforcing bar to a reinforcing bar assembly carriage.

[0008]

According to the present invention, a rebar carrier truck having a lifter with a turntable installed upright on a carriage, and a rebar carrier truck that receives the rebar carrier truck at the rear of the self-propelled carriage and is transferred from the lifter with a turntable. And a small transport trolley provided with a fork-shaped temporary placing portion for temporarily placing the arch reinforcing bar.

[0009]

According to the arch rebar carrier constructed as described above, a predetermined amount of arch rebar is placed on the table of a lift with a revolving table of a rebar carrier to carry it to a predetermined position. Therefore, the table is lifted and turned to a posture in which the arch rebar can straddle the temporary placement portion of the small carrier. Next, the small carrier truck is moved backward to accommodate the reinforcing bar carrier, and then the table is lowered to transfer the arch reinforcing bar to the temporary placing table.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, the arch reinforcing bar carrier of the present invention comprises a reinforcing bar carrier 1 and a small carrier 10, and the arch reinforcing bar S of the arch carrier 1 is connected to the small carrier 1.
It is designed to be transferred to the reinforcing bar assembly carriage 20 via 0.

Referring also to FIGS. 2 and 3, an arch rebar carrier truck 1 is a truck 2 which is moved on a floor F (FIG. 4) by a battery locomotive (not shown), and a turntable which is erected on the truck 2. It is equipped with a lifter 3 attached. The lifter 3
Is composed of a well-known table lifter 4 fixed to the carriage 2 and a revolving table 5 provided on the top of the lifter 4. The width W of the carriage 1 is formed to be 1250 mm, for example. Reference numeral 6 in the figure is a reinforcing bar leg stand.

Referring also to FIG. 4, a small carrier 10 includes a self-propelled car 11 having a U-shape in a plane, which is open at the rear, that is, the reinforcing bar carrier 1 side, and a frame 13 provided upright on the self-propelled car 11. It consists of

The self-propelled carriage 11 is designed to travel on a rail r by a self-propelled motor 14, and the width W1 inside the carriage 11 is wider than the width W of the reinforcing bar carrier 1 ( For example, 1975 mm). A fork-shaped temporary placing portion 13 is formed on the rear portion of the frame body 12.

On the other hand, the reinforcing bar assembly carriage 20 is of a known technique, and has a roller 21 provided at the rear portion thereof, and a winch 22 and an electric chain block 23 provided at the front portion thereof.

Next, the operation will be described.

When carrying the arch rebar S, a predetermined amount (for example, 60 to 80 pieces: about 1.5 tons) of the arch rebar S is placed on the turning table 5 of the rebar carrier truck 1 and the battery relocates inside the tunnel T. Advance to the desired position.

Then, the table lifter 4 lifts the turning table 5 to a predetermined height and turns the turning table 5 by a predetermined angle. At the predetermined height, the arch rebar S reaches a height at which the arch rebar S can straddle the temporary placing portion 13 of the small carrier truck 10.
Is an angle (for example, 60 °) that does not interfere with.

Next, the small carrier truck 10 is moved backward and the truck 1
It stops at a position for receiving the reinforcing bar carrier 1 inside 1, that is, a position where the arch reinforcing bar S is located above the temporary placing section 13. Finally, the table lifter 4 is lowered, and the arch rebar S of the turning table 5 is transferred to the temporary placing section 13. By the same operation, after the arch rebars S of, for example, two of the reinforcing bar transportation vehicles 1 are transferred to the small transportation vehicle 10, the small transportation vehicle 10 is moved forward and connected to the reinforcing bar assembly vehicle 20.

[0020]

Since the present invention is configured as described above, it has the following effects. (1) It is possible to reduce the number of man-hours for carrying arch rebars in small quantities. (2) The rebar can be transferred smoothly and the time can be shortened. (3) It is possible to achieve safety without hanging it as in the conventional case.
