Description

【０００１】
【発明の属する技術分野】
本発明は、コンベアベルトやシュート等の機能表面の摩耗を防止するための耐摩耗片に関する。
【０００２】
【従来の技術】
従来、鉱石等を搬送するコンベアベルト等の表面のように、摩耗を受けやすい部分には多数の耐摩耗片を貼設或いは埋設して、同耐摩耗片によりコンベアベルト等の表面の摩耗を防止するようにしている。
【０００３】
ここで、耐摩耗片は、セラミック等の超硬質耐摩耗性素材により方形板状に形成している。
【０００４】
【発明が解決しようとする課題】
ところが、上記耐摩耗片では、方形板状に形成しているために、例えば、コンベアベルトのライニング材との連結が強固になされず、鉱石等の搬送時に耐摩耗片が鉱石等の衝撃力を直接受けて、容易に剥離してしまうという不具合があった。
【０００５】
そこで、方形板状に形成した方形板状部と、同方形板状部の下面に筒状に形成した筒状部の周面を連設して一体成形し、同筒状部中にライニング材の一部を充填して、筒状部が方形板状部のアンカー機能を果たすようにした耐摩耗片が開発されたが、筒状部の孔が小さいことから、同筒状部中へのライニング材の充填が充分になされず、方形板状部が摩耗すると、筒状部も剥離することがあるという不具合がある。
【０００６】
このように、従来の耐摩耗片では、耐摩耗機能を長期間にわたって保持させることが困難となっていた。
【０００７】
【課題を解決するための手段】
そこで、本発明では、板状に形成した上下一対の上・下板部と、両上・下板部との間に介設した左右一対の脚部とを耐摩耗性素材により一体成形すると共に、上下一対の上・下板部と左右一対の脚部との間に摩耗保護する基材の一部を充填するための基材充填空間を形成すると共に、前記下板部は、前記上板部より縮小形状となすことにより、前記上板部の平面視での投影面積よりも小さく形成したことを特徴とする耐摩耗片を提供するものである。
【０００８】
また、本発明は、上板部は、平面視にて正六角形に形成したことにも特徴を有する。
【０００９】
【発明の実施の形態】
以下に、本発明の実施の形態について説明する。
【００１０】
すなわち、本発明に係る耐摩耗片は、板状に形成した上下一対の上・下板部と、両上・下板部との間に介設した左右一対の脚部とを耐摩耗性素材により一体成形すると共に、上下一対の上・下板部と左右一対の脚部との間に摩耗保護する基材の一部を充填するための基材充填空間を形成すると共に、前記下板部は、前記上板部より縮小形状となすことにより、前記上板部の平面視での投影面積よりも小さく形成している。
【００１１】
しかも、上板部は、平面視にて正六角形に形成している。
【００１２】
【実施例】
以下に、本発明の実施例を、図面を参照しながら説明する。
【００１３】
図1〜図４に示すＡは、本発明に係る耐摩耗片であり、同耐摩耗片Ａは、板状に形成した上下一対の上・下板部1,2と、両上・下板部1,2との間に介設した左右一対の脚部3,3とを超硬質耐摩耗性素材であるセラミック素材により一体成形すると共に、上下一対の上・下板部1,2と左右一対の脚部3,3との間に摩耗保護する基材４の一部を充填するための基材充填空間５を形成している。
【００１４】
上板部１は、平面視にて正六角形に形成する一方、下板部２も、上板部１と相似形、すなわち、平面視にて正六角形に形成し、かつ、同下板部２は上板部１より縮小形状となしている。
【００１５】
このようにして、基材４中に下板部２を埋設した際に、隣接する下板部2,2間を通して基材４が基材充填空間５内に流入しやすくしている。
【００１６】
左右一対の脚部3,3は、四角形柱状に形成して、可及的に断面積を大きく形成すると共に、相互に一定の間隔を開けて配置して、両脚部3,3と上・下板部1,2とにより形成される基材充填空間５を可及的に大きく形成している。
【００１７】
このようにして、上板部１が摩耗して脚部3,3が露出した際に、可及的に断面積を大きく形成した脚部3,3により基材４の摩耗保護が図れるようにすると共に、可及的に大きく形成した基材充填空間５により下板部２が強固に基材４中に保持されて、同下板部２によるアンカー機能を良好に確保することができるようにしている。
【００１８】
従って、耐摩耗片Ａの基材４からの脱落（剥離）を確実に防止することができる。
【００１９】
次に、図５を参照しながら、本実施例にかかる耐摩耗片Ａの経時的摩耗（摩滅）の進行状態を説明する。
【００２０】
▲１▼図５(a)に示すように、摩耗保護すべき基材４に耐摩耗片Ａの上板部１の表面だけを露出させた状態にて埋設すると共に、図１にも示すように、多数のかかる耐摩耗片Ａを整然と配列している。６は目地部である。
【００２１】
▲２▼図５(b)に示すように、上板部１が摩耗される。
【００２２】
▲３▼図５(c)に示すように、上板部１が全て摩耗されて脚部3,3が露出する。
【００２３】
▲４▼図５(d)に示すように、脚部3,3が全て摩耗されて下板部２が露出する。
【００２４】
▲５▼図５(d)に示すように、下板部２が全て摩耗されるまで、基材４を摩耗保護することができる。
【００２５】
このように、本実施例では、上板部１が摩耗すると脚部3,3が露出し、同脚部3,3が摩耗すると下板部２が露出して、最終的に、下板部２が摩耗するまで基材４の摩耗を保護することができて、基材４の寿命を大幅に延長することができる。
【００２６】
この際、上下一対の上・下板部1,2と左右一対の脚部3,3との間に摩耗保護する基材４の一部を充填するための基材充填空間５を形成しているため、同基材充填空間５内に基材を確実に充填することができて、下板部２による上板部１と脚部3,3のアンカー機能を十分に確保することができる。その結果、上板部１や脚部3,3が基材４から剥離するという不具合の発生を確実に防止することができる。
【００２７】
しかも、上板部１は、平面視にて正六角形に形成しているため、基材４の表面に多数の耐摩耗片Ａを上板部１の表面が露出するようにして埋設する際に、同耐摩耗片Ａを容易に整然と配列することができる。
【００２８】
特に、耐摩耗片Ａを円弧状の曲線に沿わせて配列する作業が容易となり、基材４の形状等に適応させた配列が確実に行える。
【００２９】
その結果、基材４の耐摩耗性を良好に確保することができて、同基材４の寿命を大幅に延長することができる。
【００３０】
ここで、基材４は、摩耗を保護すべきゴム素材である場合が多く、例えば、コンベアベルトの場合にはライニング材に相当するものである。
【００３１】
なお、本実施例では下板部２を平面視正六角形に形成しているが、同下板部２の形状はこれに限られるものではなく、上板部１の平面視での投影面積よりも小さければ、どの様な形状でもよい。
【００３２】
【発明の効果】
本発明によれば、次のような効果が得られる。
【００３３】
（１）請求項１記載の本発明では、板状に形成した上下一対の上・下板部と、両上・下板部との間に介設した左右一対の脚部とを耐摩耗性素材により一体成形すると共に、上下一対の上・下板部と左右一対の脚部との間に摩耗保護する基材の一部を充填するための基材充填空間を形成すると共に、前記下板部は、前記上板部より縮小形状となすことにより、前記上板部の平面視での投影面積よりも小さく形成している。
【００３４】
このようにして、摩耗保護すべき基材に上記した耐摩耗片を上板部の表面が露出するようにして埋設しておくことにより、上板部が摩耗すると脚部が露出し、同脚部が摩耗すると下板部が露出するようにすることができ、最終的に、下板部が摩耗するまで基材の摩耗を保護することができて、基材の寿命を大幅に延長することができる。
【００３５】
この際、上下一対の上・下板部と左右一対の脚部との間に摩耗保護する基材の一部を充填するための基材充填空間を形成しているため、同基材充填空間内に基材を確実に充填することができて、下板部による上板部と脚部のアンカー機能を十分に確保することができる。その結果、上板部や脚部が基材から剥離するという不具合の発生を確実に防止することができ、しかも、前記下板部は、前記上板部の平面視での投影面積よりも小さく形成しているため、基材中に下板部を埋設した際に、隣接する下板部間を通して基材が基材充填空間内に流入しやすくなる。
【００３６】
（２）請求項２記載の本発明では、上板部は、平面視にて正六角形に形成している。

BACKGROUND OF THE INVENTION
The present invention relates to a wear-resistant piece for preventing wear on functional surfaces such as conveyor belts and chutes.
[0002]
[Prior art]
Conventionally, a number of wear-resistant pieces have been affixed or embedded in parts that are susceptible to wear, such as the surface of conveyor belts that carry ore etc., and the wear-resistant pieces prevent wear on the surface of conveyor belts and the like. Like to do.
[0003]
Here, the wear-resistant piece is formed in a square plate shape from an ultra-hard wear-resistant material such as ceramic.
[0004]
[Problems to be solved by the invention]
However, since the wear-resistant piece is formed in a square plate shape, for example, the connection with the lining material of the conveyor belt is not strengthened, and the wear-resistant piece has an impact force such as ore when conveying ore. There was a problem that it was directly received and easily peeled off.
[0005]
Therefore, a rectangular plate-shaped portion formed into a square plate shape and a cylindrical surface formed on the lower surface of the rectangular plate-shaped portion are continuously formed and integrally formed, and a lining material is formed in the cylindrical portion. A wear-resistant piece was developed in which a part of the cylindrical part was filled so that the cylindrical part fulfills the anchor function of a rectangular plate-like part, but since the hole in the cylindrical part is small, When the lining material is not sufficiently filled and the rectangular plate-shaped portion is worn, there is a problem that the tubular portion may be peeled off.
[0006]
Thus, it has been difficult for conventional wear-resistant pieces to maintain the wear-resistant function over a long period of time.
[0007]
[Means for Solving the Problems]
Therefore, in the present invention, a pair of upper and lower upper and lower plate portions formed in a plate shape and a pair of left and right leg portions interposed between the upper and lower plate portions are integrally formed of an abrasion resistant material. And forming a base material filling space for filling a part of the base material for wear protection between the upper and lower pair of upper and lower plate portions and the pair of left and right leg portions, and the lower plate portion includes the upper plate The present invention provides a wear-resistant piece characterized in that it is formed smaller than the projected area in plan view of the upper plate portion by being reduced in shape from the portion.
[0008]
The present invention is also characterized in that the upper plate portion is formed in a regular hexagonal shape in plan view.
[0009]

That is, the wear-resistant piece according to the present invention comprises a pair of upper and lower upper and lower plate portions formed in a plate shape and a pair of left and right leg portions interposed between the upper and lower plate portions. And forming a base material filling space for filling a part of the base material for wear protection between the pair of upper and lower upper and lower plate portions and the pair of left and right leg portions, and the lower plate portion Is smaller than the projected area in plan view of the upper plate portion by being reduced in shape from the upper plate portion .
[0011]
Moreover, the upper plate portion is formed in a regular hexagonal shape in plan view.
[0012]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0013]
A shown in FIGS. 1 to 4 is a wear-resistant piece according to the present invention. The wear-resistant piece A includes a pair of upper and lower plate portions 1 and 2 formed in a plate shape, and both upper and lower plates. A pair of left and right legs 3 and 3 interposed between the parts 1 and 2 are integrally formed of a ceramic material which is a super-hard wear-resistant material, and a pair of upper and lower plate parts 1 and 2 are A base material filling space 5 for filling a part of the base material 4 to protect against wear is formed between the pair of legs 3 and 3.
[0014]
The upper plate portion 1 is formed in a regular hexagonal shape in plan view, while the lower plate portion 2 is also similar to the upper plate portion 1, that is, a regular hexagonal shape in plan view, and the lower plate portion 2 Is smaller than the upper plate portion 1.
[0015]
In this way, when the lower plate portion 2 is embedded in the base material 4, the base material 4 easily flows into the base material filling space 5 between the adjacent lower plate portions 2 and 2.
[0016]
The pair of left and right legs 3, 3 are formed in a quadrangular column shape and have a cross-sectional area that is as large as possible. A base material filling space 5 formed by the plate portions 1 and 2 is formed as large as possible.
[0017]
In this way, when the upper plate portion 1 is worn and the leg portions 3 and 3 are exposed, the base material 4 can be protected against wear by the leg portions 3 and 3 having the largest possible cross-sectional area. In addition, the lower plate portion 2 is firmly held in the base material 4 by the base material filling space 5 formed as large as possible so that the anchor function by the lower plate portion 2 can be secured satisfactorily. ing.
[0018]
Accordingly, it is possible to reliably prevent the wear-resistant piece A from dropping (peeling) from the base material 4.
[0019]
Next, with reference to FIG. 5, the progress of wear (abrasion) with time of the wear-resistant piece A according to the present embodiment will be described.
[0020]
(1) As shown in FIG. 5 (a), the substrate 4 to be protected against wear is embedded with only the surface of the upper plate portion 1 of the wear-resistant piece A exposed, as shown in FIG. In addition, a large number of such wear-resistant pieces A are arranged in an orderly manner. 6 is a joint.
[0021]
(2) As shown in FIG. 5 (b), the upper plate portion 1 is worn.
[0022]
(3) As shown in FIG. 5 (c), the upper plate portion 1 is entirely worn and the legs 3, 3 are exposed.
[0023]
(4) As shown in FIG. 5 (d), the legs 3, 3 are all worn and the lower plate 2 is exposed.
[0024]
(5) As shown in FIG. 5 (d), the substrate 4 can be protected against wear until the lower plate portion 2 is completely worn.
[0025]
As described above, in this embodiment, when the upper plate portion 1 is worn, the leg portions 3 and 3 are exposed, and when the upper leg portion 3 and 3 is worn, the lower plate portion 2 is exposed, and finally the lower plate portion. The wear of the substrate 4 can be protected until 2 wears, and the life of the substrate 4 can be greatly extended.
[0026]
At this time, a base material filling space 5 for filling a part of the base material 4 for wear protection is formed between the pair of upper and lower upper and lower plate portions 1, 2 and the pair of left and right leg portions 3, 3. Therefore, the base material can be reliably filled into the base material filling space 5, and the anchor function of the upper plate portion 1 and the leg portions 3 and 3 by the lower plate portion 2 can be sufficiently ensured. As a result, it is possible to reliably prevent the occurrence of the problem that the upper plate portion 1 and the leg portions 3 and 3 are peeled off from the base material 4.
[0027]
Moreover, since the upper plate portion 1 is formed in a regular hexagonal shape in plan view, a large number of wear-resistant pieces A are embedded on the surface of the base material 4 so that the surface of the upper plate portion 1 is exposed. The wear-resistant pieces A can be easily and orderly arranged.
[0028]
In particular, the work of arranging the wear-resistant pieces A along an arcuate curve is facilitated, and the arrangement adapted to the shape of the base material 4 can be reliably performed.
[0029]
As a result, the wear resistance of the base material 4 can be ensured satisfactorily, and the life of the base material 4 can be greatly extended.
[0030]
Here, the base material 4 is often a rubber material whose wear should be protected. For example, in the case of a conveyor belt, the base material 4 corresponds to a lining material.
[0031]
In the present embodiment, the lower plate portion 2 is formed in a regular hexagonal shape in plan view, but the shape of the lower plate portion 2 is not limited to this, and is based on the projected area of the upper plate portion 1 in plan view. If it is small, any shape may be sufficient.
[0032]
【The invention's effect】
According to the present invention, the following effects can be obtained.
[0033]
(1) In the first aspect of the present invention, a pair of upper and lower upper and lower plate portions formed in a plate shape and a pair of left and right leg portions interposed between the upper and lower plate portions are wear resistant. A base material filling space is formed between the upper and lower pair of upper and lower plate portions and the pair of left and right leg portions, and a portion of the base material for wear protection is filled between the upper and lower pair of upper and lower plate portions and the lower plate. The portion is formed to be smaller than the projected area in plan view of the upper plate portion by being reduced in shape from the upper plate portion .
[0034]
In this way, the above-mentioned wear-resistant piece is embedded in the base material to be wear-protected so that the surface of the upper plate portion is exposed, so that the leg portion is exposed when the upper plate portion is worn. The lower plate part can be exposed when the part is worn, and finally the wear of the base material can be protected until the lower plate part is worn, greatly extending the life of the base material. Can do.
[0035]
At this time, since the base material filling space for filling a part of the base material for wear protection is formed between the upper and lower pair of upper and lower plate portions and the pair of left and right legs, the base material filling space The base material can be reliably filled in, and the anchor function of the upper plate portion and the leg portion by the lower plate portion can be sufficiently ensured. As a result, it is possible to reliably prevent the occurrence of a problem that the upper plate portion and the leg portion are peeled off from the base material , and the lower plate portion is smaller than the projected area in plan view of the upper plate portion. Since it forms, when a lower board part is embed | buried in a base material, a base material becomes easy to flow in into a base material filling space through between adjacent lower board parts.
[0036]
(2) In this invention of Claim 2, the upper board part is formed in the regular hexagon by planar view.
[0037]
Thus, when a large number of wear-resistant pieces are embedded on the surface of the base material so that the surface of the upper plate portion is exposed, the wear-resistant pieces can be easily and orderly arranged.
[0038]
In particular, the work of arranging the wear-resistant pieces along an arc-like curve becomes easy, and the arrangement adapted to the shape of the base material can be surely performed.
[0039]
As a result, the wear resistance of the substrate can be ensured satisfactorily, and the lifetime of the substrate can be greatly extended.
