DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a track-type working machine in which a protective band is attached to the outer periphery of the track band.

B. Prior art Track-type work machines equipped with endless track belts formed by linking a large number of track shoes with pins, etc. include civil engineering machines such as backhoes and bulldozers;
There are agricultural and transportation machines such as tractors. The above-mentioned track-type work machine is suitable for operating work on flexible ground such as fields and fields, and uneven ground due to the track belt equipped with it. However, since the above-mentioned working machines are large and heavy, and the tracks that make up the track belt are made of metal, they are not suitable for running on smooth roads, and in particular, they are not suitable for running on paved roads. It is prohibited because it damages surfaces. Therefore, when moving a track-type work machine to a work site, the work machine is loaded onto a large wheel-type carrier such as a trailer and transported to the destination location. For this reason, it takes time to load and unload the working machine onto the transport vehicle, and when the working machine is transported over a short distance, there is a drawback that the operating efficiency is poor. Furthermore, if the road leading to the destination was very narrow, there were cases where it was impossible to drive the wheeled transport vehicle to the destination.

For this reason, moving a tracked working machine over a short distance on a paved road, or moving on a narrow paved road where wheeled vehicles cannot enter, has conventionally been carried out as follows.

That is, a predetermined number of old tires are laid on the path of the tracked working machine on a paved road, and the track belt of the tracked working machine runs on the old tires, and the track belt of the tracked working machine runs on the old tires. This prevents damage to the paved road surface. However, in this case, as the track-type work machine moves, the worker must move and install the old tires that were at the back of the work machine one by one to the front of the work machine, and this must be repeated. The disadvantage was that it required several workers. Also,
Another method is to construct a strip-shaped floor plate by chaining together plate-like members made of rubber, plastic, etc., and to lay this plate on the path of the track-type working machine. In this case as well, the floor plate had to be moved along with the movement of the working machine, and moving the floor plate was a heavy labor.

C. Purpose of the Invention There is no need to use old tires or floorboards, there is no need to transport track-type work machines using wheel-type carriers, and track-type work machines can be tracked without damaging the paved surface even on narrow roads where wheel-type carriers cannot enter. To provide a track type working machine in which a protective band is held and attached to the outer periphery of a track band so as not to come off so that the mold working machine itself can be moved.

D. Structure of the Invention A protective band is provided with a protective band that is made up of a large number of rectangular shock absorbing plates made of shock absorbing materials such as rubber, plastic, aluminum, etc., and is chained together by stripes, and is removably attached to the entire circumference of a track belt. The vehicle body frame supports the track of the track belt, and is composed of a plurality of sets of guide rollers installed upright so as to be located on both sides of the track belt. This is a track-type work machine that guides a protective band attached to the entire circumference in a clamp-like manner.

E. Embodiment FIGS. 1 and 2 are drawings showing a protective belt 1 which is a component of the present invention, and the protective belt 1 is made of a shock absorbing plate A made of rubber, plastic, aluminum, etc. as shown in the figure. Configure.

The illustrated shock absorbing plate A includes a main plate 2 having approximately the same length as the width of the track shoes 9' of the working machine, and
The main plate 2 and the spacers 3 are arranged alternately, and are connected by a strip 4 in an endless band shape. In addition, the main plate 2 and spacer 3 are arranged in the direction of the short side thereof.
a through hole 5 through which a strip 4 for chaining is inserted;
5 and 6 are drilled. Moreover, when the main plates 2 and spacers 3 are arranged alternately and chained together by the strips 4, the four corner parts 2a, 2 on the longitudinal side of the main plate 2
Of the corners b, 2c, and 2d, the corner portions 2c and 2d located on the inner circumferential side of the protective band 1 are cut diagonally as shown in FIG. The protective band 1 is designed to be easily bent when formed. Further, the spacer 3 has a block shape smaller than the main plate 2, and has four corner parts 3a, 3b, 3c, and 3d on the longitudinal side.
are cut diagonally to facilitate bending of the protective band 1.

In order to form an endless protective band 1 with the main plate 2 and spacers 3, the main plates 2 and spacers 3 are alternately arranged in parallel, and the strips 4 are inserted into the through holes 5 and 6 provided in the main plate 2 and spacers 3. Insert the main plate 2
and the spacer 3, and when the penetrating ends, the strip 4 is made into an annular shape together with the chained main plate 2 and the spacer 3, and both end surfaces 4a, 4b of the strip 4 are formed with overlapping through holes 7a, 7b as shown in FIG. The strip is inserted into a metallic coupling fitting 8 provided with a strip and polymerized, and the coupling fitting 8 is pressurized to polymerize and fasten both ends of the strip. As a result, the protective belt 1 having an endless shape as shown in FIG. 2 is constructed. Note that the endless protective band 1 is made slightly larger than the outer circumference length of the endless track band 9. Further, this protective band may be formed by chaining together a large number of main plates only.

On the other hand, as shown in FIG. 4 and FIG.
b, 11b are installed facing each other at their respective parts,
A guide roller 1 is attached to each bracket 11a, 11b.
2 is rotatably attached to the outside of both side edges of the upper running surface 9a of the endless track belt 9 so as to protrude from the running surface,
A plurality of pairs of guide rollers 12 are provided.

And the protective belt 1 formed in an endless shape as described above.
is attached to the endless track belt 9 of the endless track type working machine.

To attach this protective belt, if the track-type work machine is a backhoe, etc., use the boom of the backhoe and a shovel located at the tip of the boom to tilt the entire track-type work machine diagonally, and attach it to both sides of the work machine. Of the endless track belts 9, 9 located,
Raise one of the endless track belts 9 slightly from the ground. In this state, the protective belt 1 is attached to the outer periphery of the endless track belt lifted from the ground while being fitted between the guide rollers 12, 12 on both sides.
In this way, the protective belt 1 is also applied to the other track belt.
Attach. The attached protective band 1 is held with both side edges substantially in contact with the guide rollers 12, 12 on both sides.

In a track-type work machine with a protective belt attached to the track, the lower part of the protective belt touches the ground, and the upper part is guided by guide rollers on both sides, preventing it from falling off the track. It rotates with the rotation of the endless track belt and travels easily. Further, the protective belt can be easily removed from the track belt by using the opposite method to that used for attaching the protective belt.

F. Effects of the Invention In the present invention, a protective band consisting of a plurality of impact-absorbing plates made of impact-absorbing material chained together in a strip is fitted onto the outer periphery of a track belt of a track-type working machine. When a track-type work machine is run on a paved road, there is always a protective band between the track and the road surface, which used to be in direct contact with the road surface, so there is no need to worry about damaging the road surface.
The conventional complicated work such as laying old tires or floor plates is omitted, and the work machine can be driven on paved roads by a single driver, resulting in an extremely large reduction in labor. In addition, the protective belt attached to the endless track belt is held and guided by the guide rollers on both sides, so even if the protective belt loosens along with the loosening of the endless track belt during running, the guide rollers may cause it to shift significantly in the lateral direction. The machine always rotates normally together with the endless track without coming off the endless track, allowing the working machine to run smoothly.
