ことを特徴とする反転式挟搬機である。(Means for Solving Problems) The present invention has been made in view of the above-described drawbacks, and can reliably grip even an object to be sandwiched such as a tubular concrete product, and can always be held in a vertical position. An object of the present invention is to provide an inversion type sandwiching machine having a simple structure capable of gripping a sandwiched object and transporting it in a vertical or horizontal position.
The gist of this is that the common rod and the two side rods located on both sides are connected symmetrically and in parallel by the two upper and lower link rods, and the upper or lower link rods are symmetrically upward. To the end of the link rod, connect the hanging rod to the pantograph shape, and connect the hook to the hanging rod,
Furthermore, a gripping member having both sides symmetrically bent in opposite directions is rotatably connected to the lower side of each of the side rods, and a balancer for horizontally orienting each gripping member in a free state is attached. It is a type sandwich machine.

される。A rubber plate is preferably stretched on the opposite surface of the grip member. Further, it is desirable that the shape be bent inwardly into a substantially V shape with an obtuse fan angle, but even if a curved radius is provided to match the curvature of the tubular object to be carried. Good. The V shape here includes not only those having such a radius but also a wing shape. Furthermore,
A balancer for horizontally positioning the gripping member is attached to the gripping member when the gripping member is free, that is, when not in the gripping state.

方に２本のリンク杆が連結している。すなわち、この上
下のリンク杆は、平行となって、側杆と共通杆とを連結
し、共通杆を共通の１辺として２つの平行四辺形が形成
されている。On the other hand, between the central common rod and the side rods on both sides thereof, two link rods are connected above and below. That is, the upper and lower link rods are parallel to each other and connect the side rod and the common rod, and two parallelograms are formed with the common rod as one common side.

る。One of the link rods, preferably the lower link rod, is further extended by intersecting the connection point with the common rod, and the extension rod has a pantograph-shaped hanging rod connected to the extension tip end thereof. , The hanging rod intersects at its upper end and a common hanging hook is provided with or without a joint rod.
側杆、リンク杆、共通杆、吊下げ杆などは一重であるよ
り二重に設けるのが望ましい。It is desirable that the side rod, the link rod, the common rod, the hanging rod, and the like are provided in double rather than in single.
側杆相互の間には、両者の離開が直線的に行なわせるバ
ーガイドを設けるとよい。A bar guide may be provided between the side rods so as to linearly separate the two.
（作用） 本考案は以上のように構成されているので、被挟搬物を
把持部材の間に置き、把持部材を水平に位置させ、フッ
クをクレーンなどで上方に持ち上げる。(Operation) Since the present invention is configured as described above, the object to be pinched is placed between the gripping members, the gripping member is positioned horizontally, and the hook is lifted upward by a crane or the like.

られ、移動されることになる。所定の載置位置に到着し
たならば、被挟搬物を把持部材と共に、９０度回転させ
地上に横向き状態で降ろす。When lifted, the opening angle of the hanging rod becomes smaller, and the opening angle of the link rod connected to it becomes smaller accordingly. However, since the upper and lower link rods, the side rods, and the common rod constitute a parallel crank, only parallel movement occurs, and the side rods reduce their distance in the parallel direction. When the gap is further shortened, the gripping member circumscribes the object to be sandwiched between them, and when the object is further pulled up, a clamping force is generated, and the object to be sandwiched is suspended and moved. When the object reaches the predetermined mounting position, the object to be sandwiched is rotated by 90 degrees together with the gripping member and is laid down on the ground in a sideways state.
把持部材はフリーの状態となると、バランサーにより、
水平位置となり、縦位置にある別の被挟搬物をそのまま
把持出来る状態となる。When the gripping member becomes free, the balancer
The horizontal position is set, and another object to be sandwiched in the vertical position can be held as it is.
