Description

[Detailed explanation of the idea] The present invention relates to a pipe installation and transportation device.

Conventionally, when installing a steel pipe in a tunnel, for example, the steel pipe is placed on a trolley and transported to a predetermined position, and then the trolley is removed from the steel pipe before burying the steel pipe. However, it takes time and effort to attach the trolley to the steel pipe before transportation, and when the steel pipe is transported to a narrow place such as a tunnel, it is very time-consuming to remove the trolley from the steel pipe due to the lack of space. There was a problem that it took a while.

The purpose of this invention is to solve these problems, and the upper end of the tube is rotatably and removably attached via a pin to the upper part of the inner peripheral surface of the tube end, and is configured to be expandable and retractable toward the outside of the tube. a telescopic stay with a wheel attached to its lower end, one end of which is rotatably and removably attached via a pin to the lower part of the inner peripheral surface of the tube end, and the other end is pivotally attached to the side surface of the telescopic stay. This object is achieved by providing a pipe installation and transportation device configured with a pair of links that fix the telescopic stay in a position facing diagonally downward outside the pipe, and thereby, It can be easily attached to a pipe and can also be easily removed and removed even when the pipe is transported to a narrow place such as a tunnel.

The configuration of the present invention will be explained in detail below based on the drawings showing one embodiment thereof. In FIGS. 1 to 3, 1 is a tunnel, 2 is a rail laid on the underside of the tunnel 1, and 3 is an existing pipe already installed in the tunnel 1. Reference numeral 4 denotes a steel pipe that will be connected to the existing pipe 3, and a pipe installation and transportation device 5 according to the present invention is attached to one end of the steel pipe 4. This pipe installation and transportation device 5 includes a telescoping stay 6 having an inverted V shape when viewed from the front, and a pair of links 7.
The upper end is rotatably and removably attached to the upper part via a pin 9, and the turnbuckle 10 interposed in the middle allows it to extend and contract toward the outside of the pipe, and the lower end has wheels 11 attached to it. ing. One end of the pair of links 7 is rotatably and removably attached to the lower part of the inner peripheral surface 8 of one end of the steel pipe 4 via a pin 12, and the other end is pivotally attached to the side surface of the telescopic stay 6. It has the function of fixing the telescopic stay 6 in a position facing diagonally downward outside the tube. Reference numeral 13 denotes a truck attached to the other end of the steel pipe 4, and the truck 13 includes a support body 14 that supports the other end of the steel tube 4, and a support body 14 that supports the other end of the steel pipe 4.
4, and a steel pipe attachment wire 16 that is stretched around the outer periphery of the other end of the steel pipe 4 and locks the steel pipe 4 and the support body 14.

The operation of this configuration will be explained next. First, the first
The steel pipe 4 is transported to a predetermined position within the tunnel 1 in the state shown in the figure. Next, as shown in Fig. 4, the steel pipe 4
In order to remove the pipe installation and transportation device 5 attached to one end of the steel pipe 4, a board 17 is placed under the one end side of the steel pipe 4 to temporarily hold it. Next, a person enters the steel pipe 4, rotates the turnbuckle 10 of the pipe installation and transportation device 5, and retracts the telescopic stay 6. Then, as is clear from FIGS. 4 and 5, the upper end of the stay 6 expands outward along the pin 9, and the pipe installation and transportation device 5
is large enough to fit inside the steel pipe 4, so the pins 9,
12 is removed and removed from inside the steel pipe 4 in a folded state. Next, as shown by the dotted line in the figure, a wire rope 18 is attached to one end of the existing pipe 3 and one end of the steel pipe 4.
The steel pipe 4 is then brought closer to the existing pipe 3 using a suitable wire tightening tool. Next, the construction is completed by aligning the existing pipe 3 and the steel pipe 4, welding, and burying the steel pipe. The above operations may be repeated for subsequent operations. Note that when burying the steel pipe 4, it is economical to insert a block under the other end of the steel pipe 4, remove the cart 13, and reuse it.

In the above embodiment, an example was shown in which the turnbuckle 10 was used as the telescoping stay 6 of the pipe installation and transportation device 5, but the mechanism for extending and retracting the telescoping stay 6 is not limited to this. In addition, the pipe installation and transportation device 5
If the pair of links 7 are also configured to be extendable and retractable using turnbuckles or the like, it will be more convenient to remove the pipe installation and transportation device 5.

As described above, according to the present invention, the pipe can not only be guided along the rail, but also easily attached to the pipe, and even when the pipe is transported to a narrow place such as a tunnel, it can be easily removed and removed. I can do it,
Furthermore, it can be reused.
