Description

【0001】
【発明が属する技術分野】
本発明は、ダンプトラック荷台の耐摩耗素材の取付方法に関するものである。
【0002】
【従来の技術】
ダンプトラックの荷台は、土砂等の積載物を重力で容易に滑り降ろす構造をしているため、その積載物により摩耗が促進されるので、特に、荷台床鉄板には、抗張力鋼などの耐摩耗性に富む部材が使用されてはいるものの、最大積載量の関係から、それ程厚みのある鉄板を使用する事ができず、積載物との摩擦によりすり減って4〜5年のサイクルで鉄板の溶断切替及び新品鉄板の溶接張り替え等を繰り返す必要性があった。
【0003】
また、普通形状のトラックでは、荷台の床にゴムシートを置くことで、荷台の床部材の耐摩耗性の向上を図っているが、これと同様にダンプの荷台にもゴムシートを張り付けている例が見受けられるが、荷台の昇降という性質から、ゴムシートを接着剤等で張り付ける必要性があり、ダンプの荷台の補修、特に、荷台床鉄板の補修が生じた場合、ゴムシートを剥がす必要性が生じており、耐摩耗性の向上とは引き替えに、補修等の整備作業性の低下及び労力の負担の増大という欠点があった。
【0004】
【発明が解決しようとする課題】
解決しようとする問題点は、ダンプ荷台の上昇に伴う砕石等の積載物の降下とともにゴムシート等の耐摩耗部材が一緒に降下せずに、かつ、ゴムシート等の着脱が可能な取付方法を確立する点である。
【0005】
【課題を解決するための手段】
本発明は、床鉄板と側あおり鉄板との隅に帯鉄をボルト固定することにより、帯鉄の角がゴムシートを均等に押さえ、ゴムシート等の耐摩耗素材の接着張り付け箇所を最小にし、ゴムシート等の耐摩耗素材の着脱を可能にしたことを最も主要な特徴とする。
【0006】
【発明の実施の形態】
一方開き荷台を持つダンプ荷台の特徴である床鉄板の床受け材と側あおり枠材との位置が同じなので、この位置でゴムシート押さえ用の帯鉄をボルト止めするためのナットを溶接すれば、側あおりの鉄板及び床鉄板の塗装を傷める事が無く、また、ゴムシート押さえ帯び鉄を取り付ける為に等ピッチで数カ所の雌ねじ加工を施した鉄角材とこの鉄角材を溶接するための台形鉄板を使えば、荷台製造メーカー及び荷台仕様による床受け材と側あおり枠の間隔が異なっていても、台形鉄板をこの枠材位置に合わせたのち、この鉄角材とともに溶接すれば、ナット一個一個を溶接する場合と比べて、ゴムシート押さえ帯び鉄のボルト取付方向が均一になり、さらに、この鉄角材の雌ねじ位置を、側あおり枠位置に関係なく加工する事ができるようになった。
【0007】
【実施例】
図1は、一方開き荷台を示した斜視図であり、本発明の実施例の一つとして、荷台の床鉄板と前立板及び側あおり鉄板にそれぞれの寸法に合うゴムシートを帯鉄でボルト固定した場合の様子を示している。
【0008】
図2から図5は、等間隔で雌ねじ加工を施した鉄角材1を使用して、ゴムシート押さえ用帯鉄5をボルト固定した様子を示した部分拡大断面図であり、図2と図3は、鉄角材1を床鉄板と側あおり鉄板に、それぞれ床受け材位置、側あおり枠材位置で直に溶接固定し、図4と図5は、この鉄角材1を角鋼角度決め台形鉄板9を使って溶接固定する場合の様子を示している。
【0009】
また、図2及び図4と図5は、側あおり上枠にゴムシート3を固定する際に、帯鉄6でボルト固定する場合の様子を示しており、側あおり上枠には、帯鉄6をボルト固定するための雌ねじ加工を施す必要があり、コボレーンシート等が備えられたダンプ荷台の場合は、このコボレーンシートを固定するためのボルト位置を利用して固定する。
【0010】
図3は、側あおり上枠にゴムシート3を固定する際に、ゴムシートが側あおり上枠の角に密着するように等辺山形鋼8を使って、ボルト固定する際の様子を示してあるが、側あおり鉄板側の辺の長さを短くした不等辺山形鋼で固定する事もできる。
【0011】
図5の様に、鉄角材の雌ねじの位置間隔は、一定になっているので、六角穴付ボルト4のボルト頭の摩耗を防ぐ目的で、この雌ねじの位置間隔と等間隔のザグリ穴を持つゴムシート10を接着張りつけした帯鉄5でゴムシート2と3を固定する事もできる。
【0012】
図6は、側あおり鉄板の下部を折り曲げ加工をした形状の荷台である舟形のダンプ荷台の場合では、ダンプ床鉄板と側あおり鉄板の隅に予め傾斜がつけられているので、この傾斜を利用して、側あおり枠位置に、ナット溶接ワッシャ11あるいはつば付ナットを埋め込む事のできるザグリ穴を施して、このワッシャ11あるいはつばの部分を溶接して、帯鉄5をボルト4で固定する方法を示してあり、この場合、ゴムシート2と3は、帯鉄5の面で固定する事になるので、帯鉄5の当たり面には、ローレーット加工などを施して、ボルト固定の際にゴムシートが食い込む形状が望ましい。
【0013】
また、図6の帯鉄の固定には、極低頭六角穴付ボルト4を使用した様子を示してあり、このボルト固定位置には、ザグリ穴を施して、ボルトの頭が、帯鉄5の中に埋もれる形にする事で、ボルトの摩耗を防いでいる。
【0014】
図7は、角鉄材を使わずに、等間隔で空けた複数個の貫通穴にそれぞれナット13を溶接固定した帯鉄14を、床鉄板と側あおり鉄板に、それぞれ床受け材位置と側あおり枠位置で溶接固定し、ゴムシート2と3を帯鉄5と帯鉄14で挟み込む形になるように、ボルト4で固定する場合の様子を示した部分断面拡大図であり、この帯鉄14は、ナット溶接をせずに等間隔に雌ねじ加工を施したものを利用する事もできる。
【0015】
図8は、コの字形軽量形鋼12をナット溶接してボルト4が取り付けられるように加工して、側あおり枠位置と床受け材位置に合うように、側あおり鉄板と床鉄板に溶接し、帯鉄5でゴムシート2と3を押さえ込む様にした取付方法を示しており、側あおり枠と側あおり枠の間では、ボルト固定しないようにして、できるだけ取付部材の軽量化を図ったものである。
【0016】
図9と図10は、等間隔で雌ねじ加工した鉄角材を角度が一定になるように溶接固定するための部材を示した斜視図であり、図9は、コの字形軽量形鋼を加工したものを側あおり鉄板と床鉄板にそれぞれ溶接固定した様子を示してあり、図10は、鉄板を折り曲げ加工して、側あおり鉄板と床鉄板にそれぞれタッピングネジで固定した様子を示してあり、どちらも、側あおり枠位置と床受け材位置の中間に固定する事で、側あおり鉄板及び床鉄板の外側の塗装を傷める事が無いように施工してある。
【0017】
図11及び図12は、図7で示した鉄角材を使用せずに、帯鉄を取り付ける為のコの字形軽量形鋼の形状を示した斜視図であり、どちらも中間位置に雌ねじ加工を施すかあるいは、裏側にナットを溶接固定していて、図11は、一枚の帯鉄を使って、ゴムシートを押さえ込む場合に使用し、図12は、図13で示すように複数枚の帯鉄でゴムシートを押さえる場合に用いるコの字形軽量形鋼の形状を示してあり、床用ゴムシートも複数枚のものを使用することで、床鉄板の補修が必要な時には、その補修箇所のゴムシートのみを外す事が可能である。
【0018】
図13は、複数枚の床用ゴムシートを使う場合を示した部分拡大断面図であり、ゴムシートを斜めにカットして重ね合わせることで、積載物を滑り降ろす時に、ゴムシートが捲れる事を防いでいる。
【0019】
【発明の効果】
以上説明したように本発明は、ダンプ荷台の床及び側あおりにゴムシートで覆っているので、積載物を降ろす時に生じる摩擦による床鉄板並びに側あおり鉄板の摩耗を防止する事ができ、また、ゴムシートの端部のみを帯鉄を使ってボルト止めを行っているので、ゴムシートの摩耗や破損あるいは、床鉄板の補修が生じた時も、ボルトを外す事で、容易にゴムシートの着脱が行える様になった。
また、ゴムの比重を約1.26kg/cm3、鉄の比重を7.85kg/cm3とした場合、幅210cm、長さ550cmの荷台床の鉄板の厚みを4.5mmの抗張力鋼から3.6mmの厚みに替えた場合、床鉄板の重量は、約81.6kgの軽量化になり、厚さ3mmの床用ゴムシートの重量は約43.7kgになり、幅70cm×長さ550cm×厚さ3mmの側あおり用ゴムシートの重量は、2枚で約29.1kgとなり、厚さ4.5mm×幅32mm×長さ550cmの帯鉄を6枚使用した場合の重量は約37.3kgであり、ゴムシート取付の為の重量増加分は、ボルト及びナットまでを含めても約130kg程度の増加に押さえる事ができるので、新車の荷台製造段階から、ゴムシートで保護するようにすれば、薄い床鉄板と側あおり鉄板を使用することね可能となり、厚めのゴムシートを取り付けたとしても、最大積載量を確保できることとなる、すなわち、ゴムの比重は鉄に比べて小さく、約6分の1程度なので、今まで厚さ4.5mmの床鉄板を張っていたものを3.6mm程度に替える事により、厚さ3mmのゴムシートを取り付けた場合でも、車両の総重量としては変わらないことになる。
さらに、ダンプ床鉄板と側あおり鉄板にゴムシートを取り付ける前に、溶接した角鋼等をともに、錆止め塗装を施すことで、床鉄板と側あおり鉄板の張り替え寿命を延ばすことができ、1年から2年といった定期的に、帯鉄やボルトの交換及び床鉄板と側あおり鉄板の錆止め補修をする事により、床鉄板や側あおり鉄板の張り替え寿命をさら事がに延ばす事が可能となった。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for attaching a wear-resistant material to a dump truck carrier.
[0002]
[Prior art]
The loading platform of the dump truck has a structure that allows the load such as earth and sand to easily slide down by gravity, so that the load promotes abrasion. Despite the use of highly flexible materials, it is not possible to use a thick iron plate due to the maximum loading capacity, and it wears out due to friction with the load and fusing of the iron plate in a cycle of 4 to 5 years There was a need to repeat switching and re-welding of a new iron plate.
[0003]
Also, in the case of trucks of normal shape, the rubber sheet is placed on the floor of the carrier to improve the wear resistance of the floor member of the carrier, but similarly, the rubber sheet is attached to the dump carrier. An example can be seen, but due to the nature of lifting and lowering of the bed, it is necessary to attach a rubber sheet with an adhesive, etc., and when the dump bed is repaired, especially when the bed iron plate is repaired, the rubber sheet needs to be peeled off However, in exchange for the improvement of the wear resistance, there is a disadvantage that the maintenance workability such as repair is reduced and the burden of labor is increased.
[0004]
[Problems to be solved by the invention]
The problem to be solved is that the abrasion-resistant members such as rubber sheets do not drop together with the load such as crushed stones due to the rise of the dump bed, and the mounting method that can attach and detach the rubber sheets etc. It is an established point.
[0005]
[Means for Solving the Problems]
The present invention, by fixing the steel band to the corners of the floor steel plate and the side tilting steel plate with bolts, the corners of the steel band evenly press the rubber sheet, minimizing the adhesion of the wear-resistant material such as the rubber sheet, The most important feature is that a wear-resistant material such as a rubber sheet can be attached and detached.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
On the other hand, the position of the floor support material of the floor iron plate, which is the feature of the dump carrier with an open carrier, is the same as the position of the side tilt frame material, so if this position is welded with a nut for bolting the band for holding the rubber sheet, The iron plate and the trapezoidal plate for welding this iron bar with several female threads at equal pitches to attach the steel sheet holding steel sheet without damaging the painting of the side iron plate and floor iron plate. If the gap between the floor support material and the side frame is different according to the carrier manufacturer and carrier specifications, if the trapezoidal iron plate is adjusted to the position of this frame material and then welded together with this iron square bar, each nut can be used. Compared to welding, the direction of mounting the bolts on the rubber sheet holding iron is uniform, and the female screw position of this iron square bar can be processed regardless of the side tilt frame position. Was Tsu.

FIG. 3 shows a state in which, when the rubber sheet 3 is fixed to the upper side frame, the bolt is fixed by using an equilateral angle steel 8 so that the rubber sheet is in close contact with the corner of the upper side frame. However, it is also possible to fix with a non-equilateral angle iron with a shorter side of the side tilting iron plate.
[0011]
As shown in FIG. 5, the spacing between the female screws of the iron square bar is constant, and therefore, in order to prevent the abrasion of the bolt head of the hexagon socket head cap screw 4, the female screws have counterbored holes at equal intervals to the spacing between the female screws. The rubber sheets 2 and 3 can also be fixed by the band 5 to which the rubber sheet 10 is adhered.
[0012]
FIG. 6 shows that in the case of a boat-shaped dump bed, which is a cargo bed having a shape obtained by bending the lower part of the side tilting iron plate, the corners of the dump floor iron plate and the side tilting iron plate are inclined in advance. Then, a counterbore hole in which the nut welding washer 11 or the flanged nut can be embedded is formed in the side tilt frame position, and the washer 11 or the brim portion is welded to fix the band iron 5 with the bolt 4. In this case, since the rubber sheets 2 and 3 are fixed on the surface of the band iron 5, the contact surface of the band iron 5 is subjected to a low rate process, etc. A shape that the sheet bites is desirable.
[0013]
In addition, FIG. 6 shows a state in which a bolt 4 with a very low head hexagonal hole is used to fix the strap, and a counterbore is formed in the bolt fixing position so that the bolt head is connected to the strap 5. By buried in the inside, the wear of the bolt is prevented.

[0019]
【The invention's effect】
As described above, since the present invention covers the floor and side tilt of the dump truck with the rubber sheet, it is possible to prevent wear of the floor iron plate and the side tilt iron plate due to friction generated when unloading the load, Since the rubber sheet is bolted only to the end using a steel band, if the rubber sheet is worn or damaged or the floor iron plate is repaired, remove the bolt to easily attach and detach the rubber sheet. Can be done.
When the specific gravity of rubber is about 1.26 kg / cm 3 and the specific gravity of iron is 7.85 kg / cm 3, the thickness of the iron plate of the loading floor 210 cm in width and 550 cm in length is 3.6 mm from 4.5 mm high strength steel. When the thickness is changed to, the weight of the floor iron plate is reduced by about 81.6 kg, the weight of the rubber sheet for the floor of 3 mm is about 43.7 kg, and the width is 70 cm × length 550 cm × thickness. The weight of the 3mm side tilt rubber sheet is about 29.1kg for two sheets, and the weight when using six strips of 4.5mm thick x 32mm wide x 550cm long is about 37.3kg. The weight increase for mounting the rubber sheet can be suppressed to about 130 kg including the bolts and nuts, so if it is protected with a rubber sheet from the stage of manufacturing the bed of a new car, it will be thin. Floor iron plate and side It is possible to use a cage iron plate, and even if a thick rubber sheet is attached, the maximum loading capacity can be secured. That is, the specific gravity of rubber is smaller than iron, about 1/6, so now By changing the steel sheet having a thickness of 4.5 mm to about 3.6 mm, the total weight of the vehicle does not change even when a rubber sheet having a thickness of 3 mm is attached.
Furthermore, before attaching the rubber sheet to the dump floor iron plate and the side railing iron plate, the rust-preventive coating is applied to both the welded square steel and the like, so that the service life of the floor steel plate and the side railing steel plate can be extended, and from one year to two years By replacing steel strips and bolts regularly and repairing the rust of the floor iron and side railing iron plate on a regular basis, it has become possible to further extend the service life of the floor iron plate and side railing steel plate.
