Description

この発明は、付着性の強いアスファルト混合物、例えば、砕石マスチックアスファルトを転圧するタイヤローラのタイヤを加熱するタイヤ加熱装置に関するものである。   The present invention relates to a tire heating apparatus for heating a tire of a tire roller for rolling a highly adherent asphalt mixture, for example, crushed stone mastic asphalt.

アスファルト舗装する場合、プラントで、アスファルトと骨材とを所定の割合で混合して所定の温度に温めたアスファルト混合物、例えば、付着性の強い砕石マスチックアスファルトを、プラントから舗装現場へダンプカーで運搬し、ダンプカーから敷き均し機へ積み替えて所定の厚さに敷き均した後、締め固め機、例えば、タイヤローラで転圧し(締め固め)、自然冷却または水を散布して強制冷却させて硬化させることにより、アスファルト舗装を行っている。   In the case of asphalt paving, the asphalt mixture in which asphalt and aggregate are mixed at a predetermined ratio and heated to a predetermined temperature in the plant, for example, crushed mastic asphalt with strong adhesion, is transported from the plant to the pavement site by a dump truck. After the dump truck is transferred to a spreader and spread to a predetermined thickness, it is rolled with a compacting machine, for example, a tire roller (consolidation), and naturally cooled or sprayed with water and forcedly cooled to cure. Asphalt pavement.

上記したように、敷き均した砕石マスチックアスファルトをタイヤローラで転圧するとき、タイヤローラのタイヤ表面が冷えていると、敷き均した砕石マスチックアスファルトが冷えたタイヤ表面に付着することにより、敷き均した砕石マスチックアスファルトが路盤から剥がれる。
そこで、敷き均した砕石マスチックアスファルトがタイヤ表面に付着して路盤から剥がれないようにするため、タイヤ表面を加熱して所定温度に昇温させ、タイヤ表面に砕石マスチックアスファルトを付着しにくくする方法が採られている。
As described above, when rolling the flattened crushed mastic asphalt with a tire roller, if the tire roller surface is cold, the flattened crushed mastic asphalt adheres to the cold tire surface and leveled. Crushed mastic asphalt peels off the roadbed.
Therefore, in order to prevent the crushed and crushed mastic asphalt from adhering to the tire surface and peeling off from the roadbed, there is a method of heating the tire surface to raise the temperature to a predetermined temperature and making the crushed stone mastic asphalt difficult to adhere to the tire surface It is taken.

上記したタイヤ表面を加熱して所定温度に昇温させる一例として、LPG(液化石油ガス)を燃焼させた熱量でタイヤ表面を加熱するLPG赤外線輻射式ヒータを、使用している。
『舗装』 株式会社建設図書発行、2004年4月号、p3(39−3)−p4(39−4)
As an example of heating the tire surface and raising the temperature to a predetermined temperature, an LPG infrared radiation heater that heats the tire surface with the amount of heat generated by burning LPG (liquefied petroleum gas) is used.
"Pavement" Construction book publication, April 2004 issue, p3 (39-3) -p4 (39-4)

上記したLPG赤外線輻射式ヒータを使用してタイヤ表面を加熱する場合、タイヤ表面を加熱する熱量の制御が困難で、熱密度が高いので、タイヤ表面が過熱されて発煙したり、タイヤのゴムが酸化することにより、タイヤの寿命が短くなったり、悪臭が発生するという問題があった。   When the tire surface is heated using the above-described LPG infrared radiation heater, it is difficult to control the amount of heat for heating the tire surface, and the heat density is high, so the tire surface is overheated and smoke is generated. Oxidation has a problem that the life of the tire is shortened and a bad odor is generated.

この発明は、上記したような不都合を解消するためになされたもので、タイヤを損傷、劣化させることなく、効率よくタイヤを加熱することのできるタイヤ加熱装置を提供するものである。   The present invention has been made to solve the above-described disadvantages, and provides a tire heating apparatus that can efficiently heat a tire without damaging or degrading the tire.

この発明は、以下のような発明である。
(1)アスファルト混合物を転圧するタイヤローラのタイヤを加熱するタイヤ加熱装置であって、飽和蒸気発生器と蒸気過熱器とを備え過熱飽和蒸気を供給する発電機を駆動源とした蒸気供給機構と、この蒸気供給機構から供給される過熱飽和蒸気を前記タイヤの所定範囲へ吹き付ける蒸気噴射ノズルとを前記タイヤローラに搭載し、過熱飽和蒸気でタイヤを加熱することを特徴とする。
(2)前記タイヤ加熱装置は、タイヤローラを上昇させる油圧ジャッキと上向きに配設された一対のサポートローラを回動可能に支承するサポートベースとを備え、前記サポートローラで支承されたタイヤローラのタイヤを定点で回転させつつ過熱飽和蒸気で加熱する走行ローラ機構を有することを特徴とする。
(3)前記一対のサポートローラは、従動サポートローラと駆動サポートローラとから成り、前記駆動サポートローラを駆動する駆動モータを備えたことを特徴とする。
The present invention is as follows.
(1) A tire heating device for heating a tire of a tire roller for rolling an asphalt mixture, the steam supply mechanism including a saturated steam generator and a steam superheater and using a generator for supplying superheated saturated steam as a drive source; A steam injection nozzle for blowing superheated saturated steam supplied from the steam supply mechanism to a predetermined range of the tire is mounted on the tire roller, and the tire is heated with the superheated saturated steam.
(2) The tire heating device includes a hydraulic jack that raises the tire roller and a support base that rotatably supports a pair of support rollers disposed upward, and the tire roller supported by the support roller It has a running roller mechanism that heats the tire with superheated saturated steam while rotating the tire at a fixed point.

この発明によれば、蒸気を供給する蒸気供給機構と、この蒸気供給機構から供給される蒸気をタイヤの所定範囲へ吹き付ける蒸気噴射ノズルとをタイヤローラに搭載したので、すなわち、蒸気でタイヤを加熱するので、タイヤを損傷、劣化させることなく、タイヤを加熱することができる。
そして、蒸気の、顕熱量に対する潜熱量は、大気圧で5.4倍、大気圧に1kg/cm2を加えた気圧で4.4倍、大気圧に2kg/cm2を加えた気圧で3.9倍であり、蒸気の総熱量を大きくできるので、効率よくタイヤを加熱することができる。
また、蒸気を供給する蒸気供給機構と、この蒸気供給機構から供給される蒸気をタイヤの所定範囲へ吹き付ける蒸気噴射ノズルと、タイヤローラのタイヤを定点で回転させる走行ローラ機構とで構成したので、タイヤローラのタイヤを走行ローラ機構上で回転させながらタイヤを加熱することができる。
したがって、タイヤローラを走行させながらタイヤを加熱するための走行路を確保できない場所でもタイヤローラを使用して舗装することができる。
また、蒸気を供給する蒸気供給機構と、タイヤを覆い、蒸気供給機構から供給される蒸気でタイヤを加熱するタイヤカバーとで構成したので、蒸気の蒸散を抑制し、風などの周囲の影響を遮断して効率よくタイヤを加熱することができ、さらに、タイヤローラのタイヤを回転させなくとも、タイヤを加熱することができる。
According to the present invention, the steam supply mechanism for supplying the steam and the steam injection nozzle for spraying the steam supplied from the steam supply mechanism to a predetermined range of the tire are mounted on the tire roller, that is, the tire is heated with the steam. Therefore, the tire can be heated without damaging or deteriorating the tire.
Then, the steam, latent heat for sensible heat is 5.4 times atmospheric pressure, 4.4 times atmospheric pressure plus 1 kg / cm 2 to atmospheric pressure, 3 pressure plus 2 kg / cm 2 to the atmospheric pressure .9 times and the total heat quantity of the steam can be increased, so that the tire can be efficiently heated.
Since the steam supply mechanism that supplies steam, the steam injection nozzle that blows the steam supplied from the steam supply mechanism to a predetermined range of the tire, and the traveling roller mechanism that rotates the tire of the tire roller at a fixed point, The tire can be heated while rotating the tire of the tire roller on the traveling roller mechanism.
Therefore, the tire roller can be used for paving even in a place where a traveling path for heating the tire can not be secured while the tire roller is traveling.
In addition, because it consists of a steam supply mechanism that supplies steam and a tire cover that covers the tire and heats the tire with the steam supplied from the steam supply mechanism, it suppresses the transpiration of steam and affects the surroundings such as wind. The tire can be shut off and the tire can be heated efficiently, and further, the tire can be heated without rotating the tire of the tire roller.

次に、発電機29を動作させて各部へ電力を供給し、水タンク23の水をポンプ24で前側、後側飽和蒸気発生器25F,25Rへ供給し、前側、後側飽和蒸気発生器25F,25Rに飽和蒸気を発生させる。
そして、例えば、前側、後側第1飽和蒸気開閉バルブ26F,26Rを閉じたままとし、前側、後側第2飽和蒸気開閉バルブ27F,27Rを開けて前側、後側第2飽和蒸気開閉バルブ27F,27Rからの飽和蒸気を350℃位まで昇温できる前側、後側蒸気過熱器28F,28Rへ供給することにより、前側、後側蒸気過熱器28F,28Rに過熱蒸気を発生させ、前側、後側蒸気噴射ノズル31F,31Rを介して前、後タイヤ13F,13Rへ過熱蒸気を吹き付け、前、後タイヤ13F,13Rを加熱する。
