Description

  The present invention relates to a pipe introducing device and a pipe introducing method for introducing a pipe material to an excavation site in the construction work of pipe materials such as a water pipe and a gas pipe.

The pipes such as gas pipes and water pipes are laid in the ground by first excavating the ground, laying pipes at the excavation site, and refilling the soil by burying them in the direction of pipe laying. By doing.
As a method of laying pipe materials, there is a method in which a pipe material loaded on a transport vehicle is lifted by a heavy machine and conveyed to the upper part of an excavation site, and then gradually lowered and laid (Patent Documents 1 and 2).
As another laying method, suspension tools having different heights are arranged around the excavation site, and the pipe material lifted by the heavy machinery is obliquely inserted into the excavation site while being suspended by the suspension device. There are a method (Patent Document 3) and a method (Patent Document 4) for transporting the pipe material by providing a second transport vehicle.

<8> Usage Method Next, a pipe introduction method when the above-described pipe introduction apparatus A is used will be described.

(1) Stop [Figure 2A]
The vehicle body 1 on which the pipe introducing device A is mounted is stopped in front of the excavation point X.
At this time, the pipe material 7 is still loaded in a state in which the pipe material 7 is still loaded on the input carriage 6 on the lifting rail 5 of the pipe introduction device A.
Further, at the excavation point X, one or more portal frames 8 are appropriately arranged.

(2) Movement of tilt table and lifting device [Fig. 2B]
(2-1) Movement of tilting table First, the tilting table 2 is tilted and fed backward.
At this time, by placing the tilting table 2 on the table 9 installed between the vehicle body 1 and the excavation point X, the tilted table 2 is stabilized and the tilt angle of the tilting table 2 is adjusted. Can do.
In order to stabilize the tilt table 2 and adjust the tilt angle, the tilt table 2 itself is provided with a spacer (not shown) whose height can be adjusted, and the spacer is grounded. The tilt table 2 may be supported by being grounded.
The slide rail 4 and the elevating rail 5 constituting the pipe introducing device A are similarly inclined and moved in conjunction with the operation of the inclined table 2.

(2-2) Movement of Lifting Device Next, the wire of the winch 21 is connected to the lifting device 3.
And the pin which has fixed the raising / lowering device 3 and the tilting base 2 is removed, and the raising / lowering device 3 is lowered | hung back, unwinding the winch 21 gradually.
At least at this point, the front side end of the pipe member 7 is detached from above the operating unit 11.

(3) Slide rail movement [Fig. 2C]
Next, the wire of the winch 21 is replaced with the slide rail 4.
And the pin which has fixed the raising / lowering apparatus 3 and the slide rail 4 is removed, the slide rail 4 is lowered | hung back, unwinding the winch 21 gradually.
Then, the auxiliary rail 42 is developed together with the lowering of the slide rail 4. The tip of the slide rail 4 or the auxiliary rail 42 is suspended and supported by the portal frame 8.
After the movement of the slide rail 4, a portion corresponding to the initial position of the slide rail 4 becomes a surplus space 41 where no rail exists, and serves as a storage portion for the elevating rail 5.

(4) Movement of lifting rail [Fig. 2D]
Next, the wire of the winch 21 is replaced with the lifting rail 5.
And the pin which has fixed the raising / lowering apparatus 3 and the raising / lowering rail 5 is removed, the winch 21 is wound down gradually, and the raising / lowering rail 5 is lowered | hung downward.
At this time, the elevating rail 5 is accommodated in a surplus space 41 generated by the movement of the slide rail 4.
In this way, the introduction path C1 is formed in which the elevating rail 5 and the slide rail 4 are integrated and extended in the front-rear direction.
At this time, as the elevating rail 5 is lowered, the charging carriage 6 and the pipe material 7 are also lowered, but the pipe material 7 is moved backward by the tilting table 2 and the elevating device 3 itself. There is no interference with the front wall of the tilt table 2.

(5) Introduction of pipe material [Fig. 2E]
Next, the wire of the winch 21 is replaced with the loading cart 6.
And the pin which has fixed the input trolley | bogie 6 and the raising / lowering rail 5 is removed, the winch 21 is gradually unwound, and the input trolley | bogie 6 with which the pipe material 7 was loaded is introduced into the excavation location X via the introduction path C1. I will do it.
When the input cart 6 is introduced to a predetermined position, the pipe material 7 is completely lifted by the portal frame 8 and the loading of the input cart 6 and the pipe material 7 is released.

(6) Laying pipe materials [Fig. 2F]
The procedure reverse to the introduction operation ((2) to (4)) is performed to return the slide rail 4 and the lifting rail 5 to the initial positions.
Then, the pipe material 7 supported by the portal frame 8 is suspended, and the pipe material is laid on the excavation site X.

According to the pipe introduction method according to the present invention, the pipe material introduction work (steps (2) to (6)) can be completed within the construction lane, and there is no need to restrict traffic in the adjacent lane.
In addition, pipes can be transported and introduced with a single device, and heavy machinery is not required.
In addition, since the introduction path is configured by the slide rail and the lifting rail that can be integrated from the divided state, the introduction gradient of the pipe material can be set lower, which is safe.

[Relationship between the vehicle body and the ramp]
The tilting table 2 according to the present invention can be realized by combining the device that the vehicle main body 1 originally has.
For example, when the vehicle body 1 is a vehicle (for example, a safety loader) having a loading platform tilting mechanism and a moving mechanism as in the first embodiment, the tilting platform 2 according to the present invention can also be used as this loading platform. Therefore, it is not necessary to provide the tilt table 2 separately.
Moreover, when the vehicle main body 1 is a vehicle provided with a fixed bed, an inclined table 2 provided with an inclination mechanism and a moving mechanism may be provided on the fixed bed.
Further, when the vehicle body 1 is a vehicle provided with a loading platform having only a tilting mechanism, the tilting table 2 according to the present invention may be a device having only a moving mechanism, and the tilting table 2 is omitted. The moving mechanism may be borne by the lifting device 3.

[Omitted tilt table and moving mechanism of lifting device]
The tilting table 2 and the lifting device 3 according to the present invention can omit a moving mechanism in the front-rear direction.
These moving mechanisms are such that the further extension of the introduction path C1 and the pipe material 7 loaded on the lifting rail 5 via the loading cart 6 do not interfere with the driver's seat 11 of the vehicle body 1 when the lifting rail 5 is lowered. It is provided for the purpose.
Therefore, if the length of the introduction path C1 and the pipe material 7 can be set to such an extent that these problems do not occur, the moving mechanism of the tilting table 2 and the lifting device 3 may be omitted.
