【発明の属する技術分野】
本発明は消防用ホースカーを装備した消防車にホースカーを積込んだり降ろしたりするためのホースカー荷役装置に関するものである。
【０００２】
【従来の技術】
従来のホースカー荷役装置は、特開平１０−１６５５３６号公報に示す如く、消防車の荷台後部に、ホースカーを積み降ろしする荷受台を地上に接地する最下降位置と、荷台面と略同一高さとなる最上昇位置との間で昇降可能に設けてある。
前記ホースカーは、左右の車輪が荷受台の上面に載置された状態で荷受台に搭載されており、消火作業時には荷受台を最下降位置まで下降させた後、ホースカーを地上へ引き出して所定位置まで移動させる。そしてホースカーに巻回状態で積載される長尺の消火用ホースを繰り出して、その端部を消防車の給水口、消火栓、或いは他のホース等と接続して消火作業を行うようになっている。
【０００３】
【発明が解決しようとする課題】
ところが前記荷役装置にあっては、ホースカーの車輪を荷受台上面に載置してあるため、ホースカーを地上へ降ろす際、荷受台を最下降位置まで下降してからでないとホースカーを降ろすことができず、迅速な消火作業を行うことができないという問題があった。
そこで本発明は、ホースカーの荷降ろし作業を迅速に行うことができるホースカー荷役装置を提供するものである。
【０００４】
【課題を解決するための手段】
本発明の請求項１では、車体側に荷受台を昇降させる荷受台昇降装置を設け、前記荷受台昇降装置にてホースカー本体に左右一対の車輪を軸支してなるホースカーを積み降ろしするようにしたホースカー荷役装置において、前記荷受台の横幅をホースカーの両車輪間の幅より短く形成するとともに荷受台の高さをホースカー本体下面の地上高より短く形成し、前記荷受台上にホースカー本体を載置するようにし、前記荷受台昇降装置は、車体側に設けられ上下方向の凹溝がある左右一対のガイド部材と、これら一対のガイド部材の下端部間に架設された下部補強桁と、前記荷受台を下部に取り付けているとともに前記凹溝内に転動可能に導入された複数のローラを有し前記ガイド部材に沿って昇降する左右一対のスライド部材と、これら一対のスライド部材の上端部間に架設された補強桁と、前記下部補強桁と前記補強桁との間に設けられ伸縮することで前記スライド部材を昇降させる昇降用シリンダとを備え、前記昇降用シリンダの上端部は前記補強桁に軸支され、前記昇降用シリンダの下端部は前記下部補強桁に対して着脱可能とした下部ブラケットに軸支されていることを特徴とするものである。
【０００５】
これにより荷受台下降時に荷受台が接地する前にホースカーの車輪を接地させることができ、ホースカーの荷降ろし作業を迅速に行うことができる。請求項２では、車体側に荷受台を昇降させる荷受台昇降装置を設け、前記荷受台昇降装置にてホースカー本体に左右一対の車輪を軸支してなるホースカーを積み降ろしするようにしたホースカー荷役装置において、前記荷受台の横幅をホースカーの両車輪間の幅より短く形成するとともに荷受台の高さをホースカー本体下面の地上高より短く形成してホースカー本体を荷受台上に載置するようにし、前記荷受台昇降装置は、車体側に設けられ上下方向の凹溝がある左右一対のガイド部材と、これら一対のガイド部材の下端部間に架設された下部補強桁と、前記荷受台を下部に取り付けているとともに前記凹溝内に転動可能に導入された複数のローラを有し前記ガイド部材に沿って昇降する左右一対のスライド部材と、これら一対のスライド部材の上端部間に架設された補強桁と、前記下部補強桁と前記補強桁との間に設けられ伸縮することで前記スライド部材を昇降させる昇降用シリンダとを備え、前記昇降用シリンダの上端部は前記補強桁に軸支され、前記昇降用シリンダの下端部は前記下部補強桁に対して着脱可能とした下部ブラケットに軸支され、前記荷受台には、当該荷受台上に位置する平板状の載置面と、この載置面の先端側の先細形状の傾斜面とを有する補助荷受台を着脱可能に設けたことを特徴とするものである。これにより、ホースカーの積み降ろし時には荷受台を使用してホースカーの荷降ろし作業を迅速に行うことができ、補助荷受台を使用することによりホースカー以外の積載物を積み降ろしすることができる。

【０００８】
前記一対のガイド部材６は、図３に示す如くそれぞれ凹溝１４を有するチャンネル材によって形成されており、前記凹溝１４同士を対向させた状態で車体５後部に固定されている。また前記ガイド部材６は、その上端開口部を閉鎖するように架設された上部補強桁１５と、下端前面に架設された下部補強桁１６とにて補強支持されている。
【０００９】
前記スライド部材７は、横断面ボックス状に形成されており、その上端部間に架設された補強桁１７にて左右のスライド部材７を補強支持するようになっている。前記スライド部材７の左右両側面には、案内板１８を有するローラ１９を回転可能に複数個突設してあり、前記ローラ１９はガイド部材６の凹溝１４内に転動可能に導入されており、前記ローラ１９を介してガイド部材６にスライド部材７が昇降自在に保持されている。
【００１０】
２０はスライド部材７を最上昇位置にて固縛するための固縛装置で、該固縛装置２０は、図１２及び図１３に示す如くガイド部材６の外側面に突設されたボス部材２１と、前記ボス部材２１内に挿入されてガイド部材６側へ水平方向に突出・退避しうる固縛部材２２とからなり、前記固縛部材２２の外端部に固定された操作レバー２３を内側へ移動させることにより、固縛部材２２の内端部が突出してスライド部材７に穿設された係合孔２４に係合するようになっている。２５はロックピンで、ボス部材２１に穿設された孔２６及び固縛部材２２に穿設された孔２７にロックピン２５を挿入することにより固縛部材２２を突出位置（図１２）又は退避位置（図１３）にてロックするようになっている。２８は鍔部材で、固縛部材２２を突出位置へ移動させた際に前記鍔部材２８がボス部材２１の外側面に当接することにより固縛部材２２が突出位置より内側へ移動するのを規制するようになっている。
【００１１】
これにより車両走行時に昇降用シリンダ８からの油漏れ等によりスライド部材７が下降する危険を確実に防止できるようになっている。
前記昇降用シリンダ８は、図３及び図７に示す如く左右一対のガイド部材６間の中間部に配設されており、昇降用シリンダ８のロッド２９先端部は前記スライド部材７の補強桁１７下面に突設された上部ブラケット３０に軸支されるとともに、昇降用シリンダ８の基部は前記ガイド部材６の下部補強桁１６後面に固定された取付部材である下部ブラケット３１に軸支されており、前記昇降用シリンダ８のロッド２９を伸縮作動することにより、スライド部材７を昇降させるようになっている。
【００１２】
前記下部ブラケット３１は、図７に示す如く平板状に形成された基板３２に、昇降用シリンダ８の基部を軸支する軸支部３３を固定してなり、前記基板３２の裏面を下部補強桁１６の後面に当接させた状態でボルト３４とナット３５にて下部補強桁１６に着脱可能に固定されている。３６は前記基板３２の裏面に突設された当板で、下部ブラケット３１の取付時に、前記当板３６の下面を下部補強桁１６の上面に当てることにより、下部ブラケット３１の上下方向の位置調整を容易に行えるようになっている。
【００１３】
これにてメンテナンス作業時にスライド部材７をガイド部材６の下方から引き出す際に、昇降用シリンダ８及び下部ブラケット３１を図１４に示す如くガイド部材６から取り外すことにより、スライド部材７の補強桁１７が下部ブラケット３１と干渉するのを回避でき、スライド部材７の着脱作業を簡単容易に行うことができる。
【００１４】
前記荷受台９は、図４に示す如く左右一対の縦フレーム３７と、前記縦フレーム３７間に固定された前後一対の横フレーム３８とを格子状に形成してなり、前記縦フレーム３７の基端部をスライド部材７下端に略水平に固定し、スライド部材７とともに荷受台９が昇降するようになっている。
また前記縦フレーム３７及び横フレーム３８の高さＨ１は図１１に示す如くホースカー本体１１の下面の地上高Ｈ２より短く形成されるとともに、左右の縦フレーム３７間の幅Ｗ１をホースカー１０の両車輪１２間の幅Ｗ２より短くなるように形成してあり、前記縦フレーム３７及び横フレーム３８の上面にホースカー本体１１を載置してホースカー１０を積み降ろしできるようになっている。これにてホースカー１０を地上へ降ろす際に、荷受台９が接地する前にホースカー１０の車輪１２が接地するため、ホースカー１０の荷降ろし作業を迅速に行うことができる。また荷受台９を格子状に形成するようにしたので、荷受台昇降装置３全体の軽量化を図ることができる。
【００１５】
３９は補助荷受台であって、該補助荷受台３９は図１５乃至図１７に示す如く荷受台９より幅広に形成された平板状の載置面４０を有し、前記載置面４０の基部下面には矩形状の窪み部４１を形成してある。これにて前記窪み部４１を荷受台９に填め込み、荷受台９の縦フレーム３７内面に固定された取付ブラケット４２と、補助荷受台３９の窪み部４１に固定された取付ブラケット４３とをボルト４４とナット４５により連結固定することにより、荷受台９に補助荷受台３９を固定できるようになっている。
【００１６】
前記補助荷受台３９の先端部には先細形状の傾斜面４６を形成してあり、図１８に示す如く補助荷受台３９を接地させることにより、ホースカー１０以外の積載物、特に下面までの地上高が荷受台９の高さＨ１より低いカート４７の積み降ろし作業を行えるようになっている。また補助荷受台の横幅を荷受台より幅広に形成してあるため、幅広の積載物であっても積み降ろし作業を行うことができる。
尚、本実施の形態では荷受台を格子状に形成してあるが、平板状に形成しても同様の作用効果を有するものである。
【００１７】
本発明は前記の如き構成で次に作用について説明する。
図１の走行状態から荷受台９に搭載されたホースカー１０を地上に降ろす場合は、まず固縛装置２０によるスライド部材７の固縛を解除する。固縛解除は図１２の固縛状態からロックピン２５をボス部材２１の孔２６から抜き取り、操作レバー２３にて固縛部材２２を退避位置まで移動させて固縛部材２２の内端部とスライド部材７の係合孔２４との係合を解除する。この状態でロックピン２５を再びボス部材２１の孔２６から挿入すると、図１３の如くロックピン２５が固縛部材２２の孔２７を貫通して固縛部材２２は退避位置にてロックされる。これによりスライド部材７は固縛解除されて下降可能な状態となる。
【００１８】
次いで昇降用シリンダ８を収縮作動させると、スライド部材７とともに荷受台９が下降し、荷受台９が接地する直前まで下降すると、図１０の如くホースカー１０の車輪１２が接地する。車輪１２が接地すると昇降用シリンダ８の収縮作動を停止させ、ホースカー１０を荷受台９より引き出して地上に降ろす。
その際、荷受台９が接地する前にホースカー１０を地上に降ろすことができるので、ホースカー１０の荷降ろし作業を迅速に行うことができる。
【００１９】
ホースカー１０を地上から消防車１に積込む場合は、前述と逆の順序で行う。次に補助荷受台３９を使用してカート４７を消防車１に積み込む場合は、まず荷受台９に補助荷受台３９を固定する。補助荷受台３９の固定は、図１５の如く荷受台９の上面に補助荷受台３９をその窪み部４１に荷受台９を填め込むように載置し、荷受台９の取付ブラケット４２に補助荷受台３９の取付ブラケット４３を当接させる。この状態でボルト４４とナット４５にて両取付ブラケット４２、４３を連結固定し、補助荷受台３９を荷受台９に固定する。この状態で補助荷受台３９を最下降させて接地させた後、図１８の如く補助荷受台３９先部の傾斜面４６からカート４７の車輪１２を乗り上げて補助荷受台３９の載置面４０にカート４７を積み込む。
【００２０】
ところで前記荷受台昇降装置３は、定期的にスライド部材７のローラ１９等の部品修理又はその交換作業を行うが、この場合はガイド部材６からスライド部材７を取り外して修理等を行う。
以下、スライド部材７の取り外し作業について説明すると、まず前述の如く固縛装置２０によるスライド部材７の固縛を解除し、昇降用シリンダ８を上部ブラケット３０及び下部ブラケット３１から取り外す。次に、下部ブラケット３１を固定してあるボルト３４とナット３５との螺合を解除し、図１４の如く下部ブラケット３１をガイド部材６の下部補強桁１６から取り外す。この状態でスライド部材７を下方へ移動させると、スライド部材７をガイド部材６の下端から取り外すことができる。
【００２１】
その際、スライド部材７の補強桁１７が、ガイド部材６の下部ブラケット３１と干渉することがないので、スライド部材７を簡単容易に取り外すことができる。
スライド部材７を取り外した後は、ローラ１９等の修理若しくは交換作業を行う。
【００２２】
【発明の効果】
以上の如く本発明の請求項１では、荷受台の横幅をホースカーの左右一対の車輪間の幅より短く形成するとともに、前記荷受台の高さをホースカー本体下面の地上高より短く形成して、ホースカー本体を荷受台に載置するようにしたので、荷受台下降時に荷受台が接地する前にホースカーの車輪を接地させることができ、ホースカーの荷降ろし作業を迅速に行うことができる。
請求項２では、前記荷受台に先細形状の傾斜面を有する補助荷受台を着脱可能に設けるようにしたので、ホースカーの積み降ろし時には荷受台を使用してホースカーの荷降ろし作業を迅速に行うことができるとともに、補助荷受台を使用することによりホースカー以外の積載物を積み降ろしすることができる。

[0016]
A tapered inclined surface 46 is formed at the tip of the auxiliary load receiving table 39. By grounding the auxiliary load receiving table 39 as shown in FIG. However, the cart 47 can be loaded and unloaded, which is lower than the height H1 of the receiving platform 9. In addition, since the lateral width of the auxiliary load receiving base is wider than that of the load receiving base, it is possible to carry out loading and unloading work even for a wide load.
In the present embodiment, the load receiving platform is formed in a lattice shape, but the same effect can be obtained even if it is formed in a flat plate shape.
[0017]
Next, the operation of the present invention will be described.
When lowering the hose car 10 mounted on the load receiving platform 9 from the traveling state of FIG. 1 to the ground, first, the lashing of the slide member 7 by the lashing device 20 is released. To release the lash, the lock pin 25 is removed from the hole 26 of the boss member 21 from the lashed state of FIG. 12, and the lashing member 22 is moved to the retracted position by the operation lever 23 to slide with the inner end of the lashing member 22. The engagement with the engagement hole 24 of the member 7 is released. When the lock pin 25 is inserted again from the hole 26 of the boss member 21 in this state, the lock pin 25 penetrates the hole 27 of the lashing member 22 as shown in FIG. 13 and the tying member 22 is locked at the retracted position. As a result, the slide member 7 is released from being locked and can be lowered.
[0018]
Next, when the lifting cylinder 8 is contracted, the load receiving platform 9 is lowered together with the slide member 7, and when the load receiving platform 9 is lowered to just before the landing, the wheel 12 of the hose car 10 is grounded as shown in FIG. When the wheel 12 comes in contact with the ground, the retracting operation of the lifting cylinder 8 is stopped, and the hose car 10 is pulled out from the load receiving platform 9 and lowered to the ground.
At that time, since the hose car 10 can be lowered to the ground before the load receiving platform 9 is grounded, the unloading operation of the hose car 10 can be performed quickly.
[0019]
When the hose car 10 is loaded on the fire engine 1 from the ground, the order is reversed. Next, when the cart 47 is loaded into the fire truck 1 using the auxiliary load receiving table 39, the auxiliary load receiving table 39 is first fixed to the load receiving table 9. As shown in FIG. 15, the auxiliary load receiving table 39 is fixed by placing the auxiliary load receiving table 39 on the upper surface of the load receiving table 9 such that the load receiving table 9 is fitted in the recess 41, and the auxiliary load receiving table 39 is attached to the mounting bracket 42 of the load receiving table 9. The mounting bracket 43 of the base 39 is brought into contact. In this state, the mounting brackets 42 and 43 are connected and fixed by the bolt 44 and the nut 45, and the auxiliary load receiving table 39 is fixed to the load receiving table 9. In this state, after the auxiliary load receiving table 39 is lowered to the ground, the wheels 12 of the cart 47 are picked up from the inclined surface 46 at the tip of the auxiliary load receiving table 39 as shown in FIG. The cart 47 is loaded.
[0020]
By the way, the load receiving platform elevating device 3 periodically repairs or replaces the parts such as the roller 19 of the slide member 7. In this case, the slide member 7 is removed from the guide member 6 and repaired.
Hereinafter, the removal operation of the slide member 7 will be described. First, the lashing of the slide member 7 by the lashing device 20 is released as described above, and the lifting cylinder 8 is removed from the upper bracket 30 and the lower bracket 31. Next, screwing of the bolt 34 and the nut 35 to which the lower bracket 31 is fixed is released, and the lower bracket 31 is removed from the lower reinforcing beam 16 of the guide member 6 as shown in FIG. When the slide member 7 is moved downward in this state, the slide member 7 can be removed from the lower end of the guide member 6.
[0021]
At this time, since the reinforcing beam 17 of the slide member 7 does not interfere with the lower bracket 31 of the guide member 6, the slide member 7 can be easily and easily removed.
After removing the slide member 7, the roller 19 or the like is repaired or replaced.
[0022]
【The invention's effect】
As described above, in claim 1 of the present invention, the width of the load receiving table is formed shorter than the width between the pair of left and right wheels of the hose car, and the height of the load receiving table is formed shorter than the ground height of the lower surface of the hose car body. Since the hose car main body is placed on the load receiving table, the wheels of the hose car can be grounded before the load receiving table contacts the ground when the load receiving table is lowered, and the unloading work of the hose car can be performed quickly.
In Claim 2, since the auxiliary load receiving base having a tapered inclined surface is detachably provided on the load receiving base, the unloading operation of the hose car can be performed quickly using the load receiving base when the hose car is loaded and unloaded. In addition, it is possible to load and unload loads other than the hose car by using an auxiliary load receiving platform.
