〔発明の利用分野〕
本発明は荷役機器に係り、特に高放射線下の機
器の倒状および起立を遠隔操作で行な得るに好適
な梃子式起立スタンドに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to cargo handling equipment, and particularly to a lever-type standing stand suitable for remotely controlling equipment under high radiation conditions.

As described in Japanese Patent Laid-Open No. 55-2134, the conventional device does not have a lifting point for the crane hook, but is attached to the device itself, and it is estimated that there is only one lifting point. Since this point is on the center of gravity of the equipment, the support point of the crane to be erected as is and the center of gravity of the stand are aligned on a vertical line in the upright state. Therefore, the crane is free on a plane perpendicular to the vertical line, and the stand is erected. This inertial force, which cannot be stopped immediately before, causes a large impact on the stand and equipment, leading to damage.

起立スタンドを提供するにある。[Object of the Invention] The object of the present invention is to constantly apply downward force to the crane hook from the start of the stand to the end of the stand (standing upright) by changing the lifting position of the crane in a lever-type standing stand. There is a stand provided.

The present invention places the equipment on a lever-type standing stand,
It has been confirmed through experiments that when the stand is raised by operating the crane, the stand shakes significantly just before it stands upright, causing a shock to the equipment. In order to solve this problem, the lifting work is not done in one go, but the lifting position is changed twice to avoid being under the straight line between the two points mentioned above.
以下、本発明の一実施例を第１図により説明す
る。
An embodiment of the present invention will be described below with reference to FIG.
本発明の構成は第１図に示す通り、箱形をした
主スタンド１に補助スタンド５が両側から挾むよ
うに置かれ、支点となる主軸２を通しブラケツト
１０と共に、定盤４に組立てられている。 As shown in FIG. 1, the structure of the present invention is that a box-shaped main stand 1 is placed with auxiliary stands 5 sandwiching it from both sides, and is assembled on a surface plate 4 together with a bracket 10 through a main shaft 2 serving as a fulcrum. .
吊具３と吊具８はロツクピン７，１１によつて
主スタンドおよび補助スタンドに取付られてい
る。 The hanger 3 and the hanger 8 are attached to the main stand and the auxiliary stand by lock pins 7,11.
ロツクピン６は主スタンドと補助スタンドが所
定の角度でお互いに保持できるように固定するも
のである。 The lock pin 6 is used to fix the main stand and the auxiliary stand so that they can be held together at a predetermined angle.

衝撃的に定盤４に倒れる、このため起立スタンド
は勿論機器にも致命的な損傷を与える。 The operation of the present invention is as shown in FIG.
Attach the assembly crane hook with the lock pin 11. Next, raise the stand as shown in Figure 3 and gradually raise the stand. If you continue to raise the crane to Figure 4, the combined center of gravity of the main stand and the equipment will be W 1 . , as shown in the figure, is located to the left of the vertical line of the main shaft 2, which is the fulcrum of the main stand. This is a state in which the main stand can fall down naturally, so the movement of the crane just before this causes inertia and the main stand is subject to impact. This causes fatal damage to not only the stand but also the equipment.
これを防ぐため、第３図の支点および重心位置

補助スタンドにバランスウエイト１３を設ける構
造とする。 To prevent this, when the fulcrum and center of gravity are in the relationship shown in FIG. 3, the crane operation is temporarily stopped and the main stand is fixed to the auxiliary stand 5 with the lock pin 6. Next, remove the crane hook from the hoist 3 and replace it with the hoist 8 on the auxiliary stand. At this point, the crane is gradually raised, but as shown in Figure 5, the combined center of gravity of the main stand and the equipment is to the left of the fulcrum main axis 2. The structure is such that a balance weight 13 is provided on the auxiliary stand so that the moment can overcome this even if the stand is positioned.

According to this embodiment, the moment to the right of the vertical line of the fulcrum main shaft 2 shown in FIG. This has the effect of making it possible to work on a standing stand.
尚、スタンドの起立における一連の作業である
クレーンフツク、ロツクピンおよび吊具の取付
け、取外しはすべてマニピユレーターで行な得れ
る構造となつている。 The structure is such that a manipulator can be used to perform all of the installation and removal of crane hooks, lock pins, and hangers, which is a series of operations for raising the stand.
