Description

[Detailed Description of the Invention] The present invention includes a vehicle body and a working arm provided on the vehicle body so as to be freely rotatable around a vertical axis and swingable up and down around a horizontal axis. Regarding a work vehicle in which a plurality of hoses are installed with a flexure that allows the arms to swing and swing, it is possible to clamp the hoses without causing them to become loose from each other, and to allow the arms to swing and swing. To avoid damaging the hose by applying excessive force between the clamping member and the hose due to the above-mentioned problems.

Next, embodiments of the present invention will be described in detail based on the drawings.

A swivel base 2 is provided on a traveling vehicle body equipped with a crawler traveling device 1 so as to be able to freely rotate around a vertical axis P.
A control section 3 is provided on the vehicle body, and an excavation device 5 is provided on the front portion of the vehicle so as to be able to freely rotate around the vertical axis Q via a swing bracket 4. On the other hand, an earth removal device 6 is provided on the traveling vehicle body, making it possible to dig side ditches. The work vehicle is configured so that it can perform ground excavation work and also perform soil removal work while traveling.

The excavation device 5 includes the swing bracket 4,
A working arm 9 is pivotably connected to a boom 7 and an arm 8 so as to be swingable up and down around the horizontal axis R, and a bucket 10 is swingably connected to the tip of the working arm 9. The swing bracket 4 and the boom 7, the boom 7 and the arm 8, and
Hydraulic cylinder 1 is installed between arm 8 and bucket 10 respectively.
1... is installed, and the cylinder 11 is inserted from the swivel base 2 side.
A hydraulic hose 12 is constructed over...

Each of the hoses 12 is connected as a whole to a manifold 13 installed on the swivel base 2 and a holding part 14 on the back of the boom 7, and is connected to a working arm between the manifold 13 and the holding part 14. It is provided with a flexure to allow rotation and rocking of the holder 9, and is clamped at a midway point by a clamp 15 to prevent variations.

The clamp 15 includes clamping members 17 that clamp the hoses 12 as a set from above and below, and also clamp the hoses 12 in a distributed manner on both sides of the threaded pin 16.
It is rotatably attached to a connecting member 18 which is elastically deformable.

That is, as shown in FIG. 4, when the working arm 9 is rotated around the vertical axis Q, even if the relative postures of the hoses 12 and the connecting members 18 change, the clamping members 17 do not rotate. Hose 12... and clamping member 1
7...Hose 12 by suppressing the relative posture fluctuation with each other.
It is constructed so that it can be held without bending it.

Incidentally, an elastic body such as rubber may be interposed at the contact surface between the hoses 12 and the clamping member 17.

In summary, the present invention provides the above-mentioned working vehicle with a clamp 1 that clamps the intermediate portions of the plurality of hoses.
5, and the clamp 15 is connected to one connecting member 18 which is elastically deformable.
Then, the hose 12...
It is characterized by being composed of a plurality of hose holding members 17 arranged in parallel and rotatably attached.

In other words, the middle part of multiple hoses 12...
The hoses 12 are held together by the clamping members 17 attached to one connecting member 18.
It has become possible to avoid the dispersion between the hoses 12 and suppress the visibility from being obstructed by the hoses 12. Moreover, the connecting member 18 is configured to be elastically deformable, and the clamping member 1 is connected to the connecting member 18.
7... each is rotatably attached, so even if the posture of the hose 12 changes due to the rotation and swinging of the working arm 9, the clamping member 17
This makes it possible to prevent the hoses 12 from being damaged due to excessive force being applied between the clamping member 17 and the hose 12.
