Description

【0001】
【発明の属する技術分野】
本発明は車台にバッテリを有するバッテリ駆動の自走式高所作業車に関する。
【0002】
【従来の技術】
従来、建物の内装工事や配電線工事等には、垂直昇降タイプの自走式高所作業車が用いられることがある。この高所作業車はその車台に装備されたバッテリから供給される電力により走行自在な車台の前部に垂直方向に伸縮自在な伸縮マストが取付けられている。この伸縮マストには作業者の搭乗する作業台がその床面が地面に対して水平に取付けられていて、伸縮マストに内蔵された昇降機構がバッテリから供給される電力によって作動することで伸縮マストの伸縮に伴って作業台が昇降する。
【0003】
上記の自走式高所作業車のバッテリはその長手方向を車台の前後方向に向け、車台の左右両側部に複数のバッテリを別々に独立して収納し、車台の上面に設けられたバッテリ収納蓋を開閉することで、バッテリ液の補充、もしくはバッテリの交換といったメンテナンスを行うようになっている。
【0004】
【発明が解決しようとする課題】
しかしながら、このバッテリ収納蓋は車台上に取り付けられた伸縮マストが全縮状態にあって作業台の床面が車台の直上の位置に位置するときは、作業台の床面と車台の上面との間隔が狭いために、車台の上面の収納蓋を開けただけでは容易にメンテナンスを行うことができない。このため、バッテリのメンテナンスを行うためにはバッテリ収納蓋を開けて作業台を上昇させる必要があった。
【0005】
また、上記のような自走式高所作業車はその車台の左右両側部にそれぞれの左右のバッテリを別々に独立して配置してあるため、バッテリをバッテリ収納部から取り出してそれぞれのバッテリのメンテナンスを行うためには作業者が自走式高所作業車の左右の側にその都度移動しなければならなかった。
【0006】
本発明はこのような問題に鑑みてなされたものであり、作業台が車台の直上の位置に位置していても、バッテリのメンテナンスを簡単に行うことができるような自走式高所作業車を提供することを目的としている。
【0007】
【課題を解決するための手段】
上記問題を解決するため、本発明に係る自走式高所作業車は、走行装置(例えば、実施形態における車輪2f,2r)を有して自走可能な車台と、車台上に設けられた昇降手段(例えば、実施形態における伸縮マスト3)と、昇降手段に取り付けられて昇降自在な作業台と、車台に載置され、走行装置及び昇降手段を駆動するための電力を供給するバッテリとを備えて構成される。その上で、車台の幅方向両側面に前記車台を貫通するように開口する収納空間(例えば、実施形態におけるバッテリ収納部25)を有し、収納空間内に車台幅方向に延びてバッテリを収納するように構成され、車台の両側面のいずれの側からもバッテリを挿入及び引出できることを特徴とする。
【0008】
上記のような構成の自走式高所作業車によれば、車台内部のバッテリ収納部から車幅方向両側面の開口を通して車台幅方向外側にバッテリを引き出すことができるため、伸縮マストが全縮状態にある場合で作業台の床面が車台の直上にあるときであっても、車台の上面に設けられたバッテリ収納蓋を開けるために作業台を上昇させることなくバッテリのメンテナンスを行うことができる。
【0009】
また、複数のバッテリをそれらの長手方向を車台の幅方向に向け、車台の前後方向に並んだ状態に配置することで、自走式高所作業車の左右いずれの側からも複数のバッテリを一度に取り出すことができるので、作業者は車台の左右両側に移動することなく複数のバッテリのメンテナンスを行うことができる。そして、自走式高所作業車を作業現場にある壁の壁際に停止させた場合にも、作業者は高所作業車に対してその壁と反対の側の車台の側面から複数のバッテリを一度に取り出すことができる。
【0010】
【発明の実施の形態】
以下、本発明の好ましい実施の形態を図1から図3に基いて説明する。図1に本発明に係る自走式高所作業車(以下、「高所作業車」という。)の一例を示す。この高所作業車1は図1に示すように、自走可能な車台2と、前輪2f及び後輪2rからなる走行装置と、伸縮マスト3と、作業台4と、昇降機構5とから構成される。
【0011】
車台2は直方体の箱形形状をなし前後左右に車輪2f,2rを備え、前輪2fは各々車台2に内蔵された図示しない駆動モータの駆動により走行する。これらの駆動モータは車台2内に内蔵されたバッテリ21から供給される電力によって駆動を行う。また後輪2rは従動輪で、車台2の操舵を行うときは後輪2rの向きを変え前輪2fに回転差を生じさせることで車台2の向きを変える。
【0012】
伸縮マスト3は、車台2上に配設された第1マスト部材3a、第2マスト部材3b、第3マスト部材3cおよび作業台取り付けマスト部材3dの各マスト部材とが入れ子式に構成されている。また作業台取り付けマスト部材3dには作業台取り付けマスト部材3dの伸縮とともに昇降自在な作業台4がその床面が地面に水平に配設され、作業台取り付けマスト部材3dおよび作業台4の床面に手摺6が作業台4に搭乗した作業者を囲むように平面視でほぼU字形の形状をなして取付けられている。
【0013】
昇降機構5は以下のような構成となっている。まず第1マスト部材3aの内部には油圧を与えたときにシリンダロッド11aが伸長する油圧シリンダ11が配設され、第1マスト部材3aの天板を貫通したシリンダロッド11aの先端が第2マスト部材3bの天板の内面に固着されている。第3マスト部材3cの内壁には第3マスト部材3cの伸縮作動用の第1チェーン12aの一端が固着されている。第1チェーン12aは第2マスト部材3bの上部に備えられた第1スプロケット13aに掛け回され、第2マスト部材3bの内部を通り第1マスト部材3aの上部に他端が固着されている。また、作業台取り付けマスト部材3dの内壁には作業台取り付けマスト部材3dの伸縮作動用の第2チェーン12bの一端が固着されており、第2チェーン12bが第3マスト部材3cの上部に備えられた第2スプロケット13bに掛け回され、第3マスト部材3cの内部を通り第1スプロケット13aに他端が固着されている。
【0014】
上記のような昇降機構5においては、例えば作業台4の上昇は、バッテリ21から供給される電力により作動する図示しない電動モータが図示しない油圧ポンプを駆動し、当該油圧ポンプから吐出する作動油を油圧シリンダ11に供給してシリンダロッド11aを伸長させることによって行われる。シリンダロッド11aが伸長すると、シリンダロッド11aの先端に固着された第2マスト部材3bが伸長して第1スプロケット13aも第1マスト部材3aに対して上昇する。第1スプロケット13aが上昇すると第1チェーン12aを介して第3マスト部材3cが引き上げられる。また第3マスト部材3cが引き上げられると、第2スプロケット13bも第2マスト部材3bに対して(つまり第1スプロケット13aに対し)上昇する。そして作業台取り付けマスト部材3dが第2チェーン12bを介して上昇するとともに作業台4が上昇する。
【0015】
ここで昇降機構5は必ずしもバッテリ21から供給される電力によって油圧シリンダ11を作動させるものに限定されるものではなく、例えばバッテリ21から供給される電力によって作動するウインチにより伸縮マスト3に取り付けられたワイヤの巻き取り及び繰り出しを行うことで作業台4を昇降させてもよい。
【0016】
作業台4には複数の操作レバー7が配設されており、このうちの走行制御用の操作レバー7を操作することで高所作業車1の前進、後退及び操舵を行い、また昇降制御用の操作レバー7を操作して図示しない油圧ポンプにより作動する油圧シリンダ11の伸縮動を制御することで伸縮マスト3を伸縮させる。
【0017】
図2に示すように車台2の中央部は車台2の幅方向に渡って窪んでいて車台2の側面が開口しており、バッテリ21を水平な状態にして、車台2の窪んだ部分に取り付けられた板状のバッテリ収納棚22上に載置し、バッテリ21を車台2の両側面から出し入れできるようになっている。車台2には載置されたバッテリ21を覆うように車台2の左右の側面カバー23a,23b及び上面カバー24が取り付けられていて、バッテリ収納棚22と側面カバー23a,23b及び上面カバー24とで囲まれた空間(以下、「バッテリ収納部25」という。)にバッテリ21を収納することができる。
【0018】
車台2の左右の側面カバー23a,23bはそれぞれヒンジ26を介して車台2の幅方向に揺動自在に取り付けられており、バッテリ21をバッテリ収納部25から取り出すときは、ヒンジ26を回動中心として側面カバー23a,23bを車台2の幅方向外側にバッテリ21の取り出しを容易にする位置まで展開させる。またバッテリ収納棚22にはバッテリ収納棚22をスライドさせてバッテリ21を取り出すための図示しないスライド機構が設けられ、バッテリ21はこのバッテリ収納棚22ごとスライド機構に支持されながら、バッテリ21のメンテナンスをすることができる位置まで車台2の幅方向外側にスライドする。
【0019】
板状の上面カバー24は、車台2を補強するために車台2の長手方向に取り付けられた2本のフレーム27の間に、ボルト28によって車台2に取り外し自在に締結されており、ボルト28を緩めて上面カバー24を車台2から取り外すことで車台2に対して上方からバッテリ21のメンテナンスを行ってもよい。
【0020】
バッテリ収納部25には2個のバッテリ21a,21bがそれらの長手方向を車台2の幅方向に向け、車台2の前後方向に並んだ状態でバッテリ収納部25から着脱自在に収納されている。そして左右の側面カバー23a,23bを車台2の幅方向外側に展開させ、バッテリ収納棚22に取り付けられたスライド機構を使って高所作業車1の左右いずれの側からも2個のバッテリ21a,21bを一度に取り出すことができる。
【0021】
ここで、上記のような構成の高所作業車1を用いてバッテリ21のメンテナンスを行う場合の一例について説明する。ここで言うバッテリ21のメンテナンスとは、バッテリ21のバッテリ液の補充もしくはバッテリ21の交換等を言う。
【0022】
まず、作業台4に搭乗している作業者は高所作業車1を所望の位置に停止させる。そして操作レバー7を操作して伸縮マスト3を全縮状態に伸縮させ、作業台4から降りる。このとき例えば高所作業車1を進行方向に対して左側にある壁の壁際に停止させた場合には、作業者は高所作業車1の進行方向に対して右側の側面カバー23bに手を掛けて、ヒンジ25を回動中心として側面カバー23bを車台2の幅方向外側(矢印Aの方向)に側面カバー23bの内側(バッテリ収納部25側)の面とバッテリ収納棚22とが同一の面上になるまで下方に展開させる。
【0023】
その後図3に示すように作業者はバッテリ21の取手21cに手を掛けて2個のバッテリ21a,21bをバッテリ収納部25からスライド機構によって支持されたバッテリ収納棚22ごと車台2の側方に引き出す。このときスライド機構によって、バッテリ21のメンテナンスをすることができる位置までバッテリ収納棚22がスライドする。また側面カバー23a,23bが、バッテリ21がバッテリ収納棚22から車外に脱落することを防止するストッパとなる。バッテリ21を車台2の側方に引き出した作業者はバッテリ液の補充もしくはバッテリ21の交換等のメンテナンスを行う。
【0024】
メンテナンスの終了後は、バッテリ収納棚22の上に載っているバッテリ21a,21bをバッテリ収納部25に押し込む。バッテリ21a,21b全体がバッテリ収納部25に収納されたら側面カバー23bに手を掛け、側面カバー23bを車台2の幅方向内側(矢印Aと逆方向)に回動させて閉じる。そして作業者は作業台4に搭乗して高所作業を続行する。
【0025】
また、高所作業車1が隘路にて停車し、車台2の左右いずれの側にもバッテリ21を引き出せる空間がない場合には、作業台4を上昇させボルト28を緩めて上面カバー24を車台2から取り外してバッテリ21を露出させ、バッテリ21の上側からバッテリ21のメンテナンスを行ってもよい。
【0026】
【発明の効果】
以上説明したように、本発明に係る自走式高所作業車においては、バッテリを載置された車台の中から車台幅方向外側に引き出すことができるため、伸縮マストが全縮状態にある場合で作業台の床面が車台の直上にあるときでも、車台に設けられたバッテリ収納蓋を開けるために作業台を上昇させることなくバッテリのメンテナンスを行うことができる。
【0027】
また、複数のバッテリをそれらの長手方向を車台の幅方向に向けて、車台の前後方向に並んだ状態に配置することで、自走式高所作業車の左右いずれの側からも複数のバッテリを一度に取り出すことができるので、作業者は車台の左右両側に移動することなくバッテリのメンテナンスを行うことができる。この場合、高所作業車を壁際に停止させた場合にも、作業者は高所作業車に対して壁と反対の側の車台の側面から複数のバッテリを一度に取り出すことができる。

【The invention's effect】
As described above, in the self-propelled aerial work vehicle according to the present invention, the battery can be pulled out from the chassis on which the battery is placed to the outside in the chassis width direction. Thus, even when the floor surface of the workbench is directly above the chassis, battery maintenance can be performed without raising the worktable to open the battery storage cover provided on the chassis.
[0027]
In addition, by arranging a plurality of batteries in a state in which the longitudinal direction thereof is oriented in the width direction of the chassis and in the front-rear direction of the chassis, the plurality of batteries can be located on either side of the self-propelled aerial work vehicle. Can be taken out at once, so that the operator can perform maintenance on the battery without moving to the left and right sides of the chassis. In this case, even when the aerial work vehicle is stopped near the wall, the operator can take out a plurality of batteries from the aerial work vehicle at a time from the side of the chassis opposite to the wall.
