Description

[Detailed explanation of the idea] Industrial applications The present invention relates to a tube conveyor.

BACKGROUND TECHNOLOGY When a sewage pipe or the like is to be laid in a passage for installing an existing pipe or shield, the pipe must be transported to a predetermined installation position. For this reason, it has conventionally been common practice to install a pipe transport rail in the installation path, and to slide the pipe on this pipe transport rail to transport the pipe to a predetermined installation position.

Problems that the invention aims to solve However, with this conventional method, the problem is that it takes time and effort to install the pipe transport rail, and the pipe receives sliding resistance from the pipe transport rail, requiring a large amount of transport power. There is.

SUMMARY OF THE INVENTION An object of the present invention is to solve these problems and provide a pipe conveying tool that is easy to carry and does not require large conveying power.

Means for Solving the Problems In order to solve the above problems, the present invention provides a truck having a frame that is inserted into a horizontal pipe, and frame parts corresponding to the front and rear parts of the truck. a pair of jacks provided; a beam placed between the elevating members of both jacks and inserted into the tube to support the upper inner surface of the tube; A front wheel of the truck configured to be able to rise and fall; a rear wheel of the truck provided at the rear of the frame; and a front end of the frame further forward than the front wheel; A guide ring that can run on the bottom of the inner surface of another pipe that has already been installed in the horizontal direction when inserted into the inside of this pipe.

Operation In such a configuration, when transporting a pipe, the frame of the truck is passed horizontally into the pipe together with the beam, and both jacks raise the beam to support the upper inner surface of the pipe. Since the pipe is thereby lifted, the pipe can be transported to a predetermined installation position by driving the truck using the front wheels and rear wheels. In the predetermined laying position, insert the front end of the frame into another horizontal pipe that has already been laid,
A guide wheel is run within this pipe. Then, the load on the front part of the truck can be received by this guide wheel, and by raising the front wheel toward the frame, the leading end can be lifted off the conveyance path. Therefore, it is possible to connect this pipe to another existing pipe while the pipe remains supported on the cart without the front wheel getting in the way.

Embodiment In FIGS. 1 to 3, reference numeral 1 indicates a laying passage, and a new pipe 2 is laid within this passage 1. tube 2
is made of FRP material or the like, and has a socket 3 at one end and a socket 4 at the other end. 5 is another pipe, which has already been laid in the passage 1.

6 is a conveyor based on the present invention. here 7
1 is a truck, which includes a frame 8 that is inserted into a horizontal pipe 2 and whose front and rear ends protrude from the pipe 2, and a front wheel 9 provided at the front of the frame 8.
and a rear wheel 10 provided at the rear end of the frame 8. The front wheel 9 has a caster structure, and only one wheel is provided at the center of the frame 8.
A pair of rear wheels 10 are provided on both sides of the frame 8. A guide wheel 11 having the same configuration as the front wheel 9 is provided at the front end of the frame 8 further forward than the front wheel 9 . These front wheels 9 and guide wheels 11 have a male-threaded support shaft 12 screwed into a receiving portion 13 of the frame 8, and can be moved up and down relative to the frame 8 by rotating this support shaft 12. It's like that.

A pair of jacks 14, 14 are provided on the frame 8 at positions corresponding to the front and rear parts of the truck 7, respectively. 15 is its operating handle, and 16 is its elevating member. both jacks 1
A horizontal beam 17 is passed between the elevating members 16, 16 of 4 and 14, and this beam 17 is also inserted into the inside of the tube 2 like the frame 8. By raising the jacks 14, 14, the beam 17 can come into contact with the upper inner surface of the tube 2 and lift the tube 2, thereby supporting the tube 2. Steady prevention plates 18 whose edges are in contact with the inner circumference of the tube 2 at appropriate intervals are installed at appropriate intervals in the length direction of the beam 17 to prevent the tube 2 from swinging around the beam 17. It is prevented. Also,
A handle 19 is provided at the rear end of the frame 8 to allow the trolley 7 to travel in response to an input.

In such a configuration, when transporting the pipe 2 toward a predetermined installation position in the installation passage 1,
First, the truck 7 is passed through the interior of the tube 2 placed in the horizontal direction, and its front wheels 9 and rear wheels 10 are made to protrude from the openings at both ends of the tube 2. Next, operate the jacks 14, 14 to raise the beam 17, and move this beam 17 to the tube 2.
Lift this tube 2 by placing it on the upper inner surface of the tube. Thereby, the tube 2 is supported by the truck 7 via the beam 17. Note that the tube 2 is supported with the insertion port 4 on the front side of the truck 7 and the socket 3 on the rear side.

Next, the handle 19 is pushed to move the trolley 7 toward a predetermined laying position within the laying passage 1. At the predetermined installation position, first, the tip of the frame 8 is inserted into the socket 3 of the existing pipe 5. Then the guide wheel 11
The guide wheel 11 runs along the bottom of the inner surface of the tube 5, and the load of the front part of the truck 7 can be received by the guide wheel 11. Note that the height position of the guide ring 11 is set in advance to the position of the inner bottom of the tube 2.

Next, by rotating the support shaft 12 of the front wheel 9, the front wheel 9 is raised and brought closer to the frame 8. As a result, the socket 3 of the pipe 5 and the front wheel 9 do not come into contact with each other even when the trolley 7 is running, so the socket 4 of the pipe 2 is inserted into the socket 3 of the pipe 5, and both pipes 2, 5 are joined together. Incidentally, by hooking the hook 20 onto the socket 3 of the tube 2 and pulling it toward the tube 5, the socket 4 can be easily inserted into the socket 3. Further, the jacks 14, 14 are operated in advance so that the center height position of the tube 2 matches that of the tube 5.

When the joining of the tubes 2 and 5 is completed, the jacks 14 and 14 are operated, the beam 17 is lowered and separated from the inner surface of the tube 2, and the carriage 7 is pulled and taken out from the tube 2.

Effects of the invention As mentioned above, according to the invention, there is no need to install conventional conveyor rails on the laying path.
The pipe can be easily transported by simply running the trolley without requiring large transport power.Moreover, by running the guide wheels inside the existing pipe and lifting the front wheel from the installation path, the pipe can be easily transported without requiring large transport power. This pipe can be joined to the existing pipe while it is supported on the trolley.
