Description

本考案は高所での重量物の架設や着脱等の荷役作業をする為の高所作業車に関する  The present invention relates to an aerial work vehicle for loading and unloading heavy objects at high places.

従来、高所で足場を組まずに短期間で重量物の設置や撤去等の作業を行う場合は、重量物の規模による専用のクレーン車と高所作業車の二台の連携作業を行う状況があり効率的では無かった。  Conventionally, when work such as installation or removal of heavy objects is performed in a short period of time without assembling a scaffold at a high place, a situation where two dedicated crane vehicles and an aerial work vehicle are coordinated depending on the scale of the heavy object It was not efficient.

上記の状況を改善する目的で、下記に示す先行技術等が認知されている。
文献1の高所作業車の吊り上げ装置は、ブーム先端の作業台に小規模なウインチの吊り上げ装置を架設して荷物の吊り上げを行う目的であるが、吊り上げ能力が小規模なことと、ブームに吊り上げ荷重が相乗りすることでブームの各移動中の安定性に問題が有る。
文献2の高所作業車兼用クレーン車を高所荷役作業に使用する場合、クレーンの吊り上げ能力は一定の規模があるが、吊り上げた荷物が常に乗用作業台の下に位置するので作業台上の作業員が荷役に係れない問題が有る。
文献3はアウトリガー4基を備えた一台の車両に、2基の荷役作業ユニットが有る例として説明する、その内の1基はブーム型で他基はシザースリンク型の組み合わせであるが共に高所作業ユニットである為クレーンの荷役作業は出来ない。
For the purpose of improving the above situation, the following prior arts are recognized.
The lifting device for an aerial work vehicle in Document 1 is intended to lift a load by installing a small winch lifting device on a workbench at the end of the boom. There is a problem in stability during each movement of the boom because of the lifting load.
When the crane for both high-altitude work vehicles in Document 2 is used for high-altitude cargo handling work, the lifting capacity of the crane has a certain scale, but the lifted luggage is always located under the riding platform, so There is a problem that workers are not involved in cargo handling.
Reference 3 describes an example in which one vehicle with four outriggers has two cargo handling units, one of which is a boom-type combination and the other is a scissor-link type combination. Because it is an office work unit, crane handling work cannot be performed.

従来の高所作業は作業台座や足場を組んだ上で重量物の荷役作業等を行っていたが、工事期間の短縮を計る上から、作業員が搭乗する乗用作業台を設けた高所作業車の導入が進み現在では短期間の工事では目覚しく普及している、しかし狭い工事現場や狭隘な道路上では重量物を扱うに必要なクレーン車と高所作業車の二台を設置させることが難しく、必要のない大型クレーン車を長いリーチを利用して離れた場所に設置するなどの不都合が有った、又高所作業車の中には規模の小さな吊り上げ装置を乗用作業台に架設した機種も見られるが、吊り上げ能力が小規模なことと、作業車ブームに吊り上げ荷重が相乗りすることで作業台が移動中に不安定になる問題が有った。  In conventional high-altitude work, work loading and unloading work was carried out on a work platform and scaffolding. However, in order to shorten the construction period, high-altitude work with a passenger work platform on which workers can board is provided. The introduction of cars is progressing, and it is currently popular for short-term construction, but on narrow construction sites and narrow roads, it is possible to install two crane cars and aerial work vehicles necessary to handle heavy objects There were inconveniences such as difficult and unnecessary installation of a large crane vehicle at a remote location using a long reach, and a small lifting device was installed on a riding platform in an aerial work vehicle Although there are models, there are problems that the lifting capacity is small and that the work platform becomes unstable while moving due to the lifting load on the work vehicle boom.

課題を解決するために、車両の車体フレーム上の一端に搭載したクレーンユニットと、他端に搭載した乗用作業台を有する高所作業ユニットと、二つのユニットが共通で使用する油圧駆動源とアウトリガー装置、更に其々のユニットを独自操作する操縦手段、等を一台車両上に構成したクレーン付き高所作業車を目指す。  In order to solve the problem, a crane unit mounted at one end on the vehicle body frame of the vehicle, an aerial work unit having a riding work table mounted at the other end, a hydraulic drive source and an outrigger used in common by the two units Aiming for an aerial work vehicle with a crane, which is composed of a single unit on the vehicle, as well as a control means for operating each unit independently.

本考案を実施した場合、アウトリガー装置が共有の一台の車両に、定格荷重が保障されたクレーンユニットと高所作業ユニットを搭載すれば、定格荷重内の重量物を高所に設置及び撤去をする等の荷役作業が一台で可能となる、この効果は本考案の課題でも有った狭いスペースでの重量物を扱う高所作業が或る程度可能となる。  When the present invention is implemented, if a crane unit and an aerial work unit with a guaranteed load rating are mounted on a single vehicle shared by the outrigger device, heavy objects within the rated load can be installed and removed at a high location. Carrying work such as carrying out is possible with one unit, and this effect makes it possible to work to a certain extent at a high place handling heavy objects in a narrow space, which was also a problem of the present invention.

クレーン側を無線コントロール可能な遠隔操縦手段を用いれば、高所作業ユニット側の乗用作業台内の作業員がクレーン側も運転操作可能となり省力効果も大きくなる。  If a remote control means capable of wirelessly controlling the crane side is used, a worker in the riding work table on the high-altitude work unit side can operate the crane side, and the labor saving effect is increased.

本文中のクレーンユニットAとは伸縮ブーム3と符号のない起伏シリンダーと旋回ポストと旋回台フレームと旋回駆動装置とウインチ巻き上げ部とワイヤーとフック5と操作装置を含めた部分を言い、高所作業ユニットBとはブーム型においては、伸縮ブーム4及び先端の乗用作業台6と旋回台部と起伏シリンダーを含めた部分を言う、又シザースリンク型高所作業ユニットCとは手摺付き乗用作業台床8と上下するリンク装置を含めた部分を言う。  The crane unit A in this text refers to the part including the telescopic boom 3, the unlifted cylinder, the swivel post, the swivel frame, the swivel drive, the winch hoisting part, the wire, the hook 5, and the operating device. In the boom type, the unit B refers to a part including the telescopic boom 4, the riding platform 6 at the tip, the swivel platform, and the hoisting cylinder. The scissor link type high altitude working unit C is a riding platform with a handrail. 8 and the part including the link device that moves up and down.

図1はトラック車両の車体フレーム1に、4基のアウトリガー装置2とエンジン駆動力より取り出した油圧駆動源装置を共用として、車体フレーム1の前端に搭載型のクレーンユニットAを配置搭載し、後端にブーム式高所作業ユニットBを配置搭載した形式である、用途により前端に高所作業ユニットBを、後端にクレーンユニットAを配置することも可能である。  FIG. 1 shows that a mounting type crane unit A is arranged and mounted on the front end of a body frame 1 on a body frame 1 of a truck vehicle in common with four outrigger devices 2 and a hydraulic drive source device extracted from the engine driving force. It is also possible to arrange a high-altitude work unit B at the front end and a crane unit A at the rear end, which is a type in which a boom type high-altitude work unit B is arranged and mounted at the end.

図2はトラック車両型の高所作業車は2基のユニットで共同作業が出来る設置ポイントを選び、アウトリガー装置2を設置したあと、クレーンユニットAで重量物を吊り上げ所定の位置までブーム移動した後に高所作業ユニットBの乗用作業台内の作業員により重量物の設置取付け等の作業を施工する。  Figure 2 shows a truck-mounted aerial work platform after selecting an installation point where two units can work together, installing an outrigger device 2, lifting a heavy object with a crane unit A, and moving the boom to a predetermined position. Work such as installation and installation of heavy objects is carried out by workers in the riding platform of the high work unit B.

図3はトラック車両型高所作業車の2基のユニットの作業領域の平面図である、クレーンユニットAのフック5直下の単独作業領域は最大作業半径円a1と最小作業半径円a2で囲まれる輪状の部分であり、又高所作業ユニットBのブーム先端に架設されている乗用作業台6の中心直下の単独作業領域は最大作業半径円b1と最小作業半径円b2で囲まれる輪状の部分である、このことから2基の共同作業位置を、クレーンのフック5と乗用作業台6の中心部が垂直線上に重なる状態と想定すると図の中央部の斜線部分に成る、それ以外は各ユニットの単独作業領域となる。  FIG. 3 is a plan view of the work area of the two units of the truck vehicle type aerial work vehicle. The single work area immediately below the hook 5 of the crane unit A is surrounded by the maximum work radius circle a1 and the minimum work radius circle a2. The single work area directly below the center of the riding work platform 6 that is a ring-shaped part and is erected on the boom tip of the high-altitude work unit B is a ring-shaped part surrounded by the maximum work radius circle b1 and the minimum work radius circle b2. From this, it is assumed that the two joint work positions are in a state where the central part of the crane hook 5 and the riding work table 6 overlap each other on the vertical line. It becomes a single work area.

図4はクローラータイプの走行台車10にクレーンユニットAとシザースリンク型の高所作業ユニットCとの組み合わせを示す、シザースリンク型の高所作業ユニットCは作業半径円の領域を持たず上下方向のみに成るため、重量物を乗用作業台に積載した状態で設置ポイントまで移動すれば作業効率は良くなる。  FIG. 4 shows a combination of a crane unit A and a scissor-link type aerial work unit C on a crawler-type traveling carriage 10, and the scissor-link type aerial work unit C does not have a work radius circle region and is only in the vertical direction. Therefore, if the heavy object is loaded on the riding work table and moved to the installation point, the work efficiency is improved.
