Description

[Detailed Description of the Invention] This invention relates to a waterway creation device that allows the inner wall of a waterway of any width to be continuously lined.

Generally speaking, a channel construction device is used to continuously line the inner wall of a pre-excavated canal with water-blocking material, but conventional channel construction devices line multiple types of linings with different widths depending on the width of the channel. Because it is necessary to install the equipment, the spacing around the suspension is designed to be the widest possible. For this reason, when transporting the product, it is necessary to transport the product in multiple pieces and then reassemble it at the site, which has the disadvantage of increasing transportation costs.

This invention was made with the aim of eliminating such drawbacks, and the width of the car can be freely adjusted according to the width of the waterway to be lined, and the width of the car can be reduced within a limited range during transportation. The system provides a device that enables stable running during work and reduces transportation costs.

This invention will be described in detail below with reference to an illustrated embodiment. In the figure, reference numeral 1 denotes a vehicle body, which is composed of a long frame-like vehicle frame 2 in the front and rear, and a pair of elevating and lowering mechanisms 3 are provided in the middle of the vehicle body 1 spaced apart in the front and rear.
is provided. Since these lifting mechanisms 3 have the same configuration, one of them, that is, the front lifting mechanism 3
To explain, the elevating mechanism 3 has first links 4 that are vertically spaced apart and parallel to each other on both sides of the vehicle body 1, and the ends of these first links 4 on the vehicle body 1 side are connected to the lower part of the vehicle body frame 2. It is pivotally connected by a pin 6 to a bracket 5 installed at the intermediate portion.
Further, a support member 7 provided in the vertical direction is pivotally connected to the outer end of each first link 4 by a pin 8 to constitute a four-section parallel link mechanism, and a lower part of each support member 7 and the above-mentioned vehicle body frame are configured. Lifting cylinders 11 are installed obliquely between the brackets 10 installed on the upper part of the support member 7, and these lifting cylinders 11 allow the support member 7 to move up and down without changing its angle.

On the other hand, on the outside of each lifting mechanism 3, there is a telescopic mechanism 1.
2 is provided. The telescopic mechanism 12 also has second links 13 that are vertically spaced apart and parallel to each other. The ends of the second links 13 on the vehicle body 1 side are pivotally connected to the upper part of the support member 7 by pins 14, and the outer ends of each second link 13 are fixed to the truck frame 16 constituting the suspension 15. It is pivotally attached to the mounting frame 17 via a pin 18. Telescopic cylinders 19 are installed diagonally between the bracket 18 protruding inside the mounting frame 17 and the support member 7, and the distance between the left and right suspensions 15 can be arbitrarily changed by these telescopic cylinders 19. It's becoming like that. Suspension 1 above
5 has a crawler track 20, for example, and is capable of running independently on the left and right sides using a drive source such as a hydraulic motor (not shown), and the power supply to the drive source is mounted on the rear of the vehicle body 1. This is carried out by the power engine 21. In addition, 22 is a power supply pump, 2
3 is a fuel tank, 24 is a hydraulic oil tank, and 25 is a control room installed at the rear of the vehicle body 1.

On the other hand, support brackets 26 are provided protruding from the front of the mounting frame 17 on the left and right suspensions 15, and a support frame 27 is erected from these support brackets 26. At the top of each support frame is a lift cylinder 28.
The upper end of each lift cylinder 28 is attached, and the lower end of each lift cylinder 28 is attached with the base end of a lining device 29 installed so as to protrude toward the rear of the vehicle body 1 via a connecting pivot 30. 28 allows the lining device 29 to move up and down.

Note that 31 is an outrigger installed on both sides of the vehicle body frame 2 so as to be spaced apart from each other in the front and back, and can support the vehicle body 1.

Since this invention has been described in detail above, when installing the lining device 29 according to the width of the waterway, the outrigger 31 is grounded and the vehicle body 1 and the suspension 15 are lifted, and in this state, the lifting cylinder 11
While moving the support member 7 up and down, the telescopic cylinders 19 can be used to move each suspension 15 in the direction of contact and separation.This makes it possible to obtain an arbitrary vehicle width that matches the lining device 29, creating a stable waterway. In addition to carrying out the lining work, by minimizing each suspension 15 by the same operation as described above, it is possible to easily transport the vehicle on general roads without having to divide it into multiple parts.
