Description

【考案の詳細な説明】[Detailed description of the device]
【0001】[0001]
【産業上の利用分野】[Industrial applications]
この考案は、例えば建築現場における天井施工、配線、配管あるいは塗装等の 高所作業に用いられる自走式高所作業車の吊り装置に関する。 The present invention relates to a suspension device for a self-propelled aerial work vehicle used for aerial work such as ceiling construction, wiring, piping or painting at a construction site.
【0002】[0002]
【従来の技術】[Prior art]
従来、建築現場における天井施工、配線、配管工事、照明取付工事あるいは塗 装工事等のような高所作業では、ローリングタワーや足場を組立てて行っていた が、最近では作業の省力化と安全性の向上を図るために、走行装置を有する車台 上に昇降可能な作業台を設けてなる自走式高所作業車が多用されている。 Conventionally, rolling towers and scaffolds have been assembled for high-place work such as ceiling construction, wiring, piping work, lighting installation work, and painting work at construction sites, but recently labor saving and safety has been done. In order to improve the vehicle, a self-propelled aerial work vehicle is often used in which a work platform that can move up and down is provided on a chassis having a traveling device.
【0003】 ところで、このような自走式高所作業車を建築現場へ搬入、搬出する際には、 一般にトラックに積込んで運搬している。そして、トラックへの積込み、積降し は、歩み板を用いて自走で行うこともできるが、通常はクレーン等で吊り上げて 行っている。By the way, when such a self-propelled aerial work vehicle is carried in and out of a construction site, it is generally loaded on a truck and carried. The loading and unloading of the truck can be done by self-propelled using a step board, but usually it is done by lifting with a crane or the like.
【0004】 このため、従来よりこの種の高所作業車には、例えば図9及び図10に示すよ うに、吊り装置としての吊り金具103を車台102の四角部に設け、機体10 1を吊り上げるときには、前記吊り金具103にワイヤーロープ104を図9及 び図10に示すように掛け渡しその中央部をクレーン等のフック105に引掛け て吊り上げている。For this reason, conventionally, in this type of aerial work vehicle, for example, as shown in FIGS. 9 and 10, a suspension metal fitting 103 as a suspension device is provided in the square portion of the chassis 102 to suspend the machine body 101. At this time, the wire rope 104 is hung on the hanging metal fitting 103 as shown in FIGS. 9 and 10, and the central portion thereof is hooked on a hook 105 of a crane or the like to be lifted.
【0005】[0005]
【考案が解決しようとする課題】[Problems to be solved by the device]
しかしながら、上記のような従来の吊り装置にあっては、吊り上げ作業の際に ワイヤーロープ104等を必要とし、これを4ヶ所の吊り金具103に掛け渡し てその略中央部をクレーン等のフック105に引掛け、機体101が略水平状態 になるように吊り上げなければならないため、作業が煩雑で手間がかかると共に 、一人の操作では困難であった。 However, in the conventional lifting device as described above, the wire rope 104 or the like is required during the lifting work, and the wire rope 104 or the like is hung on the four hanging fittings 103, and the substantially central portion thereof is hooked by a hook 105 such as a crane. Since the machine body 101 has to be hung on the ground and hoisted so that the machine body 101 is in a substantially horizontal state, the work is complicated and troublesome, and it is difficult for one person to operate.
【0006】 また、ワイヤーロープ104を掛け渡すときに、機体101の塗装等の損傷を 防止するために前記ワイヤーロープ104が機体101に当る個所(例えば図9 における作業台106と手摺部107の部分、図10における作業台106部分 等)にダンボールやウエス等を挟み込まなければならないため、より一層作業が 煩雑になっていた。Further, when the wire rope 104 is hung, the portion where the wire rope 104 hits the body 101 in order to prevent damage such as painting of the body 101 (for example, the workbench 106 and the handrail portion 107 in FIG. 9). The corrugated cardboard, waste cloth, etc. must be sandwiched between the worktable 106 (in FIG. 10, etc.), and the work becomes even more complicated.
【0007】 さらに、吊り上げたときに、ワイヤーロープ104のフック105に対する引 掛け部位がずれて機体101が傾く場合があり、この場合には機体101が不安 定になり危険である。Further, when the wire rope 104 is lifted, the hooked portion of the wire rope 104 with respect to the hook 105 may shift and the machine body 101 may tilt. In this case, the machine body 101 becomes unstable and dangerous.
【0008】 そこでこの考案は、ワイヤーロープ等を別に必要とせず、しかも簡単かつ容易 に機体を略水平状態で吊り上げることができる自走式高所作業車の吊り装置を提 供することを目的とする。[0008] Therefore, an object of the present invention is to provide a hoisting device for a self-propelled aerial work vehicle that does not require a wire rope or the like and can easily and easily hoist the machine body in a substantially horizontal state. .
【0009】[0009]
