【発明の詳細な説明】 （産業上の利用分野） 本発明はゴムクローラの接地側に発生する亀裂の補修の
際に使用する器具に関する。Description: TECHNICAL FIELD The present invention relates to a device used for repairing a crack generated on the ground side of a rubber crawler.

のとなり、このためスチールコード２が腐蝕劣化される
ものとなつてゴムクローラ本体１の耐久性が大いに損わ
れるものとなる。(Prior Art) In recent years, a rubber crawler as shown in FIG. 1 has been used for the underbody of a civil engineering construction machine. However, when a scrap material or an obstacle is stepped on in rough terrain work, etc. 1 may cause a deep crack p on the ground side of the steel cord layer 2 embedded inside the rubber crawler body 1.
If it reaches the maximum value, the water will invade from the road surface, and the steel cord 2 will be corroded and deteriorated, and the durability of the rubber crawler main body 1 will be greatly impaired.
この場合、亀裂ｐは専ら隣り合うラグ3aとラグ3aの間3b

巻回部ｍ、ｍにおいて、引き伸ばされ広げられるのであ

記巻回部に於いて肉厚のラグ3a、3a部分は殆んど伸張し
ないのであり、主として肉薄のラグ間3bが伸張されるも
のとなるため、成長する亀裂はほゞラグ間3bに限られる
のである。なお、図面４は芯金である。In this case, the crack p is exclusively formed between the adjacent lugs 3a and 3b.
As shown in Fig. 2, this occurs in the winding parts m, m of the drive wheel, etc., and it is stretched and spread, and further, crushed stones are caught in the cracks and spread. As a result, the steel cord layer 2 is gradually widened and deepened. However, since the thick lugs 3a, 3a in the winding portion are hardly stretched, and the thin-walled lugs 3b are mainly stretched, the growing cracks are almost the same between the lugs 3b. It is limited to Drawing 4 shows a core metal.
ところで、上記亀裂の補修としは専らコンベヤーベルト

としてはゴムクローラを駆動輪に巻き付け彎曲せしめる
ことにより亀裂内部を拡開して自然加硫ゴムセメントを
充填したのち、所定時間彎曲状態を維持して亀裂を拡開
したまゝ充填した自然加硫ゴムセメントを硬化せしめる
のである。By the way, as the repair of the cracks, a natural vulcanized rubber cement used for filling holes in the conveyor belt is filled and hardened in the cracks.The repair method is to wind the rubber crawler around the drive wheel and bend it. After the expansion, the inside of the crack is expanded and filled with the natural vulcanized rubber cement, and then the filled natural vulcanized rubber cement is cured while the crack is expanded by maintaining the curved state for a predetermined time.
該方法によれば硬化したゴムは補修後において常にクロ

位置せしめることができない場合には、該巻回部分に位
置する亀裂のみを補修したのちゴムクローラを移動して
未補修部分を順次巻回部分に停止せしめて同様の補修を
行わねばならない。According to this method, the cured rubber is always compressed from the front and rear in the circumferential direction of the crawler body after repair, and the tightness is not impaired even at a location where the cured rubber is not sufficiently adhered. Moisture does not penetrate into the steel cord layer, but if there are multiple cracks during the repair and it is not possible to locate all of the cracks at the drive wheel location at the same time, place them at the winding portion. After repairing only the cracks, the rubber crawler must be moved and the unrepaired part must be stopped in sequence to the wound part and the same repair must be performed.
（発明が解決しようとする課題） 上記補修作業で自然加硫ゴムセメントの硬化には長時間
（約15時間〜25時間）を要することから、一本のゴムク
ローラに対して複数箇所の補修を行うことは誠に面倒な
問題となつており、不経済ながら新品と取替えることを
余儀なくされることになる。(Problems to be solved by the invention) Since it takes a long time (about 15 hours to 25 hours) to cure the natural vulcanized rubber cement in the above repair work, it is necessary to repair a plurality of locations on one rubber crawler. This is a very troublesome thing to do, and it is uneconomically forced to replace it with a new one.
本発明は上記補修作業が簡便に行われるようになすもの

構成されたことを特徴とする。(Means for Solving the Problem) A rubber crawler repairing device according to the present invention has a gentle arcuate curve whose upper outer surface of the long side is substantially the same as when the rubber crawler is attached to the winding portion of the traveling drive device. In addition, two or more recessed portions are provided at appropriate intervals on the curved upper surface, and the core plate engaging portion of the rubber crawler is suitably fitted in the recessed portions, and the recess portion of the receiving plate. It is characterized by comprising a stopper plate and a jig for tightening means such as bolts and nuts to fix the core crawler engaging portion of the rubber crawler from above in a fitted state.
本発明の作用は次の実施例の記載から明らかとなる。The operation of the present invention will be apparent from the description of the following examples.

成してある。(Embodiment) FIG. 3 shows a repairing jig used in the present invention, in which the receiving plate 5 is wound around a winding portion m (driving wheel or idler wheel) of the traveling drive device. An iron plate or a rigid plastic plate having a curved thickness of approximately equal to or less than that is used, and a plurality of curved upper side outer surfaces 5a are spaced at appropriate intervals (two in the illustrated example). The recessed portions 6, 6 are formed.

10 and 10 are inserted and fixed to the screw holes 7 and 7. In this embodiment, the vaults 10 and 10 are screwed into the screw holes 7 and fixed to each other. However, the screw holes 7 and 7 are formed so as to penetrate downward and the vaults 10 and 10 are penetrated. Insert the nut 11 from the upper side through the hole,
It may be fixed and fixed at 11. FIG. 4 shows another such example.

First, the receiving plate 5 is formed from the rolling wheel side of the rubber crawler main body 1 and the recessed portions 6 and 6 thereof have core bars. The rubber crawler body 1 is brought into contact with the engaging portion g so as to be fitted thereinto, while the stopper plate 8 is brought into contact with the rubber crawler body 1 from above the ground side, and the vaults 10 and 10 are inserted toward the screw holes 7 and screwed together. It is fixed. This makes it possible to easily fix the crack p in the repaired portion in a desired curved state.

密性を保持する上で著効を奏するものとなる。When repairing the repaired portion, the dirt and dust inside the crack p are removed and cleaned, and the rubber powder generated by buffing the portion to be the adhesive surface is removed. Both corners are cut at a constant inclination angle (approximately 5 ° to 45 °) to form a tapered surface, and the repair rubber is filled.
In this case, the formation of the tapered surface is such that the repair rubber is always compressed from the front and rear in the circumferential direction of the crawler body, which is very effective in maintaining sufficient tightness.
（発明の効果） 本発面によれば、上記の如き治具をゴムクローラの補修
