2. Description of the Related Art The endless track used in various construction machines and vehicles such as bulldozers, hydraulic excavators, and rough terrain vehicles has been mainly equipped with steel tracks until now. In order to fulfill the purpose of reducing noise and vibration, which are problems in civil engineering work and snow removal work in the area, and protecting the pavement surface, those equipped with rubber crawler belts are gradually becoming popular.

In the case of this rubber crawler belt, it is possible to stably run with the sand and sand of soft ground or wet ground interlocking between the uneven ridges formed on the tread surface of the outer circumference of the crawler belt, and also when there is snow. Also has the characteristics that it can move freely and safely on the snow when the snow mass is in the mesh state, and also has the characteristic that the paved road surface can be protected and quiet, so various constructions in urban areas where the paved road must be moved It is indispensable for snow removal, snow removal, and transportation work, but when traveling on ice-burning snow or ice such as on a road surface that has become a snowy rut or frozen on the road surface However, there is a drawback that the uneven treads on the outer surface of the crawler track cannot secure a sufficient frictional force with the road surface, which makes it difficult to secure stable maneuverability.

As a technique for solving such a problem and ensuring the frictional force between the crawler belt and the road surface even under pressure snow or ice, for example, JP-A-10-16836 and JP-A-10-297556 are disclosed. Like the anti-skid device for a vehicle crawler disclosed in, for example, by mounting the anti-slip device in a proper place on the crawler belt, the weight of the vehicle body is concentrated on the protruding member provided on the anti-slip device in a mud road or a snowy road. It has also been proposed to prevent slipping during running by cutting into the ground such as a frozen road or the like, but in the case of these conventional non-slip devices, a plurality of mountain-shaped convex Rubber crawler belt has a structure in which a projecting member is mounted and fixed on an arbitrarily selected mountain-shaped ridge portion of a crawler track formed by alternately forming a ridge portion and a valley-shaped concave portion in the moving direction. Noise and vibration, which are the characteristics of To fulfill sufficiently the purposes, such as protection of the road surface had become as causing a disadvantage that can not be.

[0005] As described above, the rubber crawler belt equipped with the conventional anti-skid device concentrates the weight of the vehicle body on the anti-slip device projection member, and exerts an excellent anti-slip effect on pressure snow or ice. However, when driving on a road surface after melting snow or after removing pressure snow or ice, or on a road surface with pressure snow or frozen parts scattered in some places, the protruding member makes strong contact with the exposed road surface and causes noise and vibration. May occur and cause scratches on the pavement road surface.Therefore, when using it, you have to pay close attention to it, such as repeatedly removing and installing it depending on the condition of the road surface. Repetition of desorption work under bad working conditions such as snow not only increases the work load, but also deteriorates the efficiency of snow removal and transportation work itself. Sasageto I had a problem such like that.

Therefore, the present invention can obtain an effective anti-slip effect on pressured snow or ice, and also does not damage the exposed paved road surface, and sufficiently generates noise and vibration. From the judgment that it is possible to obtain anti-slip for endless tracks that can be restrained in
As a result of quick and rapid development and research, and repeated trial and error over a long period of time and numerous trials and experiments, this time, finally, a new structure of anti-slip metal fittings for endless track and new anti-slip for endless track The present invention has succeeded in realizing the fitting method of the metal fittings, and the configuration thereof will be described in detail below along with an embodiment representative of the present invention shown in the drawings.

[Effect] As described above, according to the non-slip metal fittings for the endless track of the present invention, the pair of hook metal fittings are hooked on the left and right edges of the crawler belt of the endless track, and the fixing metal fittings are provided between both hook metal fittings. While changing and adjusting the separation distance and tensioning it, the fixing mechanism of the fixing metal part fixes the separation distance between the hook metal parts, and is integrated with the fixing mechanism on the outer surface of the tread of the endless track crawler track. Since the protrusions built in can be projected, the anti-slip metal fittings for the endless track can be appropriately selected from the mountain-shaped ridges and valley-shaped recesses formed in the endless track crawler track. By installing it at multiple points of the valley-shaped concave streak part, the projecting part becomes protruding from between the mountain-shaped convex streak parts, and good running stability can be obtained on bad roads such as mud roads, pressure snow, and ice. In addition, when traveling on the paved road surface, the protrusions are submerged in the valley-shaped concave stripes or It will be rolled over and hidden between the adjacent mountain-shaped ridges, and the mountain-shaped ridges will receive the weight of the car body, so noise and vibration can be suppressed and damage to the road surface can be prevented. It provides excellent features.

Furthermore, according to the method of mounting the non-slip metal fittings for the endless track of the present invention, an arbitrary number of anti-slip functions can be selected according to the road conditions such as a mud road, snow, and a frozen road. The non-slip metal fittings can be attached to the crawler track at intervals required, and the mounting work is performed by a pair of hook metal fittings on the left and right edges of the arbitrarily selected valley-shaped groove on the outer circumference of the tread of the crawler track. It is possible to attach quickly and easily by hooking the parts and adjusting the fixing metal part in a tension-like manner to fix the fixing mechanism, and also the removal work can be easily and quickly removed. Moreover, even if the projection part integrated into the fixing mechanism is worn or damaged due to repeated use and the function of slip prevention or connection fixing is impaired, only the target part can be easily replaced. Is possible, It is intended to exert Xiu the effect that it is possible to efficiently implement the desorption operation and maintenance work on the end track.

In particular, the anti-skid metal fitting 1 for an endless track described in the embodiment of FIG. 1 has, in addition to the above-mentioned features, a steel rope 31 and a fixing mechanism 4 between a pair of hook metal fittings 2, 2. U-shaped bolt 41, sandwiching plate 42 and fixing nut 4 to be formed
By using the simple structure provided with the fixing metal part 3 composed of 5 and 45, it is possible to reduce the weight and reduce the burden of transportation and detachment work, and also to prevent the steel rope 31 from being worn or damaged.
Since it is only necessary to replace the U-shaped bolt 41 and the fixing nuts 45, 45, simple and economical maintenance management can be performed. Further, substantially the same effect can be obtained also by the anti-skid metal fitting 1 for an endless track shown in FIG.

A non-slip metal fitting 1 for an endless track shown in FIG.
Has a structure in which the belt-type male metal fitting 32 and the belt-type female metal fitting 33 are connected in a state of being overlapped with each other, so that higher durability strength is secured as compared with the case where the cord 31 is used for connection. In addition, the bolts 46, 46, 46 that form the protrusions 5, 5, 5 are formed by strip-shaped male metal fittings 32 and band-shaped female metal fittings 33 formed on the strip-shaped flat plate to form the bottom of the valley-shaped recessed portion 63. Since it is supported so as to be erected relatively strongly on the rail, it is possible to enhance the anti-slip effect as compared with the case where the steel rope 31 is used. In addition, if the plate-shaped protrusion 5 having the tip edge formed in a corrugated claw shape is integrally formed with the belt-type female metal fitting 33, a stronger anti-slip effect can be obtained.

As described above, the non-slip metal fittings for an endless track and the mounting method thereof according to the present invention can achieve the intended purpose in a uniform manner by the novel constitution, and are easy to manufacture, and have been conventionally used. Compared to the non-slip device, it has a simpler structure and can be manufactured at a relatively low cost. In addition to reducing the number of parts, a fixing mechanism that doubles as a projection is assembled and mounted on an endless track. Therefore, parts replacement due to wear or damage can be performed quickly and easily by daily work, so that work efficiency of desorption work and maintenance management can be markedly improved, and cost reduction can be reliably achieved. It is highly evaluated in the construction industry and road management industry that use construction machinery and snow removal vehicles, and it is expected that it will be widely used and spread.
