Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is used by being attached to the tread side of an endless crawler track that is hooked around a large number of wheels of a tracked vehicle such as a bulldozer. Regarding the ground contact zone, the purpose is to reduce vibration and noise when tracked vehicles run on flat land, and to protect the road surface and tracks.

(Prior Art) The tracks of tracked vehicles usually have a steel structure in which a large number of links and tracks are endlessly connected to each other through bushes and pins. When driving on flat ground, it generates significant vibration and noise.
In addition, there is a risk of damaging the road surface and causing the protruding lugs of the tracks to wear out or break. The vehicle is now being run by changing to crawler tracks.

(Problem to be solved by the invention) However, elastic tracks are also expensive, and changing them requires a lot of effort and time, making them less versatile. It is also being considered to run the vehicle by fixing the plates with screws or by fitting protrusions into the mud removal holes.

However, it is not easy to screw one elastic board to a large number of shoes one by one, and moreover, the attachment and removal work is very difficult because sludge adheres to the shoes as they run.

In addition, even when elastic plates are fitted and held in the mud removal holes of the track shoes, they tend to come off relatively easily due to external forces applied during running, and conversely, if the elastic plates are designed to be difficult to come off, it becomes even more difficult to attach and detach them. Not practical.

(Means for Solving the Problems) The present invention solves the problems of the prior art described above, and eliminates the need to change to elastic tracks each time when running on a flat surface (it can be easily attached to the tread side of the track), Vibration of time
It is designed to reduce noise and protect the road surface and the tracks. Specifically, it has grooves that correspond to the protruding lugs of the tracks that are attached to the track shaft in an endless manner. a large number of ground plates, connecting plates extending from both lengthwise ends of the ground plates at a substantially right angle to the concave groove forming surface side, and a connection such as a rope that sequentially connects the extending ends of each connecting plate. This invention relates to a grounding zone for a track belt consisting of a material.

Furthermore, the invention of the present application includes a plurality of ground plates having concave grooves corresponding to the protruding tread lugs of the track shoes that are attached to the track shaft in a bandless manner, and concave grooves from both longitudinal ends of the ground plates. It consists of a connecting plate extending approximately perpendicularly to the groove forming surface and a connecting member such as a rope that sequentially connects the extended ends of each connecting plate, and each connecting plate is movable in the length direction of the connecting member. The present invention also relates to a grounding zone for a track belt, characterized in that the grounding zone is connected.

(Function) The concave groove-formed surface of each ground plate, which is sequentially connected by a connecting member such as a rope, is connected to the tread surface of each shoe shoe with a protruding lug, and the concave groove and the protruding lug of the shoe shoe are mutually connected. The connecting member, such as the rope, is then attached to the connecting member in sequence, and finally both ends of the connecting member, such as the rope, are connected and used.

If the spacing between the connecting plates does not match the spacing between the shoes to be installed, the adjacent connecting plates are sequentially moved and adjusted along the length of the connecting material and temporarily installed one after another.

(Embodiment) The specific content of the present invention will be explained below based on the embodiment shown in the drawings. 1 is a ground plate constituting the ground zone of the present invention;
Reference numeral 5 indicates a connecting member that sequentially connects the ground plates. The ground plate 1 is formed of urethane resin, rubber, other elastic materials, metal materials, etc., and is designed to overlap the tread surface of a track board 9 that is endlessly attached to a track shaft that constitutes a track belt of a bulldozer or the like. The ground plate 1 has a concave groove 2 continuous in the length direction of the ground plate having a corresponding shape to fit into at least one of the protruding lugs 10 protruding from the tread surface.
Connecting plates 3.3 extending substantially perpendicularly to the groove forming surface are provided at both lengthwise ends of the connecting plate 3.3.
A connecting hole 4 through which a connecting member 5 is inserted is provided at the extending end of the connecting hole 4.
is drilled.

Regarding the extension length of the connecting plate 3 described above, when the connecting hole 4 at the tip is aligned with the link center of the endless track belt (a position that coincides with the axis of the link) when attached to the endless track belt,
This is more preferable because the sliding between the connecting member 5 and the ground plate 1 is reduced.

The connecting member 5 is a rope such as a nylon rope or a wire rope, or a metal chain, and is inserted into the connecting hole 4 of the connecting plate 3.3, and the ground plate 1 moves in the length direction of the connecting member 5. They are freely connected in sequence.

Furthermore, a hook 6 with a retaining device is attached to one end of the connecting member 5, and a stopper 7 is attached to the other end.
A ring part 8 is formed by fixing the ring part 8 to the ring part 8 in a length-adjustable manner.

In the embodiment described above, the ground plate 1 has one concave groove 2, but it is not necessarily limited to this. In some cases, the number of grooves 2 in the ground plate 1 may be increased accordingly.

(Function) When the above-mentioned grounding zone is installed on a tracked vehicle, each grounding plate 1 is moved along the connecting member 5 to adjust the distance between them, and then the grounding plate 1 is attached to the tread surface of the track plate 9. , the concave groove 2 is fitted into one of the lugs 1o and polymerized one after another, and finally the hook 6 on one side of the connecting member is engaged with the ring portion 8 on the other side to attach it endlessly.

In this case, when adjusting the overall length of the connecting member 5, the protruding length of the ring portion 8 is set by loosening the stopper 7.

(Effects of the Invention) As described above, the present invention provides a large number of ground plates having concave grooves corresponding to the protruding lugs of the treads of the track shoes that are endlessly attached to a tracked vehicle, and a long length of the ground plates. Since it consists of connecting plates extending approximately perpendicularly to the concave groove forming surface from both ends in the horizontal direction, and connecting members such as ropes that sequentially connect the extending tips of each connecting plate, it is difficult to connect the track belt. It is extremely easy to install,
Compared to replacing with conventional urethane rollers, it is easier to work with, significantly reduces costs, reduces vibration and noise when driving on flat surfaces, and protects the road surface and track discs. .
