提案されている。2. Description of the Related Art A rubber crawler using a rubber shoe plate for road surface protection and noise prevention is used in various work machines such as carrier dump trucks and carrier tractors. This rubber crawler is suitable for work on snow.
Since the grip force of the lug projectingly provided on the track plate cannot be expected, conventionally, a chain is wound around the track plate to deal with the problem, but this cannot provide a sufficient anti-slip effect. Therefore, as disclosed in Japanese Unexamined Patent Publication No. 10-16836, there is proposed an anti-slip device including a protruding member that bites into the snow and snow surface.

り、履板を傷める不都合が生じる。However, in the above-mentioned conventional anti-slip device, the pair of left and right projecting members are connected via the chain, and both projecting members move independently of each other. Therefore, when a large load is applied to the protrusion member on one side due to the unevenness of the road surface, the load concentrates on a part of the lug into which the protrusion member on one side fits. Further, this may cause a force in the twisting direction of the track plate. Further, since the bases of the pair of hooks provided on one side are rigidly connected to the projecting member, only one of the hooks will function when tilted due to lateral displacement, and the side edge portion of the shoe plate with which the hook engages. The load concentrates on.
Therefore, a large load is partially applied to the rubber material of the shoe plate, which causes a problem of damaging the shoe plate.

It is installed between multiple lugs lined up in the direction of movement of the track.
In the above aspect, the track plate is provided through the flexible fixing member (7).
It was designed to be attached to the. According to this, since the load applied to the protrusion acts on the shoe plate via the base plate, it is possible to disperse the load from the protrusion over a wide range by using a plate material having a required rigidity such as a steel plate for the base plate, As a result, the load stress generated on the track plate can be reduced and damage to the track plate can be avoided. Moreover,
There is a high degree of freedom in designing the shape of the protrusions, and various forms can be selected according to the road surface conditions such as snow quality and freezing conditions and the structure of the work machine to be mounted. Will get better. In addition,
Load from the base plate is distributed over multiple lugs
Also allows some movement of the base plate,
It is possible to avoid applying an excessive load.
