〔産業上の利用分野〕
この考案は、船艙内作業装置の固定装置に関す
る。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a fixing device for a working device in a ship's hold.
出願人は、先に船艙内部の補修、点検等の各種
作業を行う船艙内作業装置を開発し、既に出願し
ている（特願58−90173号参照）。
The applicant has previously developed an in-ship work device for carrying out various operations such as repair and inspection inside a ship's hold, and has already filed an application for this device (see Japanese Patent Application No. 58-90173).
この船艙内作業装置は、船体の上甲板に固定さ
れる固定台と、この固定台に設置され、上甲板の
開口部より船艙内を昇降自在とされるポストと、
このポストより横方向に延在される作業台付き作
業用フレームとからなるものである。 This in-ship hold working device includes a fixed base fixed to the upper deck of the ship, a post installed on the fixed base and capable of being moved up and down inside the hold from an opening in the upper deck.
It consists of a work frame with a workbench extending laterally from the post.
ところで、船の上甲板には約20分の１程度の勾

りするばかりでなく、強風下においては転倒する
心配があつた。そこで、従来船艙内作業装置の設
置に際し、船艙内作業装置の固定台を上甲板に溶
接していた（第５図参照）。 By the way, the upper deck of a ship has a slope of approximately 1/20, so if the work equipment in the hold is simply installed on the upper deck, it will not only shift during work, but also be exposed to strong winds. I was worried about falling down. Therefore, when installing a work device in a ship's hold, the fixing base of the work device in a ship's hold was conventionally welded to the upper deck (see Fig. 5).
しかし、これだと船艙内作業後船艙内作業装置
の撤去に際し、固定台の溶接部をガス切断し研磨

部分を研磨処理して再塗装する必要があり、特に
上甲板裏面は足場がないため、僅かな補修作業で
あつても、多大な手間、工数および費用を必要と
した。 However, with this method, when removing the work equipment inside the ship's hold after work inside the ship's hold, in addition to gas cutting and polishing the welded parts of the fixed base, welding on the upper deck and the burnt part of the paint from the gas cutting process must be polished and repainted. Especially since there was no scaffolding on the back of the upper deck, even minor repair work required a great deal of effort, man-hours, and expense.

Hereinafter, this invention will be explained with reference to an embodiment shown in the drawings.The in-hold working device 1 includes a fixed base 3 fixed on the upper deck 2 of a ship, and a fixed base 3 installed on the fixed base 3. It consists of a post 5 which can be raised and lowered in the hold A through an opening 4, and a work frame 6 with a workbench extending laterally from the lower end of the post 5.
固定台３の下部周縁部には複数個のねじ式若し
くは油圧式のジヤツキ７が取付けられている。 A plurality of screw-type or hydraulic-type jacks 7 are attached to the lower peripheral edge of the fixed base 3.

ツク９が取付けられている。ジヤツキ７のロツド
８とベースブロツク９とは球面軸受け若しくは連
結ピンにより連結されている。 A base block 9 is attached to the lower end of the rod 8 of each jack. The rod 8 of the jack 7 and the base block 9 are connected by a spherical bearing or a connecting pin.
ベースブロツク９は平面上、四角形等の多角形

けられている。 The base block 9 is formed into a polygonal shape such as a rectangle or a circular shape on a plane, and inside the base block 9 are cylindrical permanent magnet steels 10, 10,
Electromagnetic coils 11, 11 are attached to the outside thereof.
電磁コイル１１，１１は例えば第３図に示すよ
うな制御回路（単相半波整流方式）によつて制御
されている。 The electromagnetic coils 11, 11 are controlled by, for example, a control circuit (single-phase half-wave rectification system) as shown in FIG.

吸引力を持続する。 To explain this control circuit, switch 1
2 is connected to terminal 13, the half-wave current flowing from terminal 14 in the AC waveform is connected to rectifier (for suction) 1.
5, the half-wave current flowing from the terminal 16 passes through the electromagnetic coil 11, passes through the rectifier 15, passes through the switch 12, and flows toward the terminal 14, and an attractive force acts on the electromagnetic coil 11. After this, switch 1
Even if the current is cut off by setting 2 to the middle level, the attractive force is maintained due to residual magnetism.

電磁コイル１１の吸引力が消滅する。 On the other hand, when the switch 12 is connected to the terminal 17, the half-wave current flowing from the terminal 16 is connected to the rectifier (for release).
18, the half-wave current flowing from the terminal 14 flows through the terminal 14, the rectifier 18, the reverse excitation series resistor 19, the electromagnetic coil 11, and the terminal 16 in this order.
The attractive force of the electromagnetic coil 11 disappears.
なお、制御回路としてこの種の制御方法の他に
三相全波整流方式がある。 In addition to this type of control method, there is a three-phase full-wave rectification method for the control circuit.

This invention consists of the above-mentioned structure, and since the fixing base of the in-hold work equipment is fixed to the upper deck by means of the electromagnetic coil and the permanent magnet steel of its inner pole, there is no need for any work such as fixing by welding. Therefore, the fixing base can be fixed very easily and reliably.
また、永久磁石鋼を内極部として使用している
ため、停電時にも使用することができる。 Additionally, since permanent magnet steel is used for the inner pole, it can be used even during power outages.
また、上甲板に勾配が付いてもジヤツキによる
レベルの調節がきわめて簡単にできる。 Furthermore, even if the upper deck has a slope, the level can be adjusted extremely easily using the jack.
