(Example) An example of the weir folding device for casting of this invention will be described based on the drawings. As shown in FIGS. 1 and 2, the casting weir folding device 1 of this embodiment has a connection pipe (the base member of this invention) connected to the lower end of the rope 2 whose upper end is connected to a gravity balancer (not shown). ) 3 is suspended, and one end of a fixed lever 5 of the actuating section 4 is fixed to the lower end of the connecting pipe 3, and an operating lever 7 is fixed to one end of the fixed lever 5 by a pivot 6. Plate-shaped brackets 8, 8 are bolted to both sides of the fixed lever 5, respectively, and a trunnion 10 holding the cylinder cover 9 is attached to the tip of the brackets 8, 8. Swing shafts 11, 11 are pivotably mounted, a hydraulic cylinder 12 is screwed into the cylinder cover 9, and hydraulic hoses 13, 13 are connected to the hydraulic cylinder 12. 13 is connected to a hydraulic pump (not shown) through an upper opening (not shown) through a lower opening 14 of the connecting pipe 3, and as shown in FIG. Inside the hydraulic cylinder 12 is a piston 15.
A rod 16 is installed inside facing the operating lever 7, and an operating tool 17 is screwed to the tip of the rod 16.
8 is rotatably connected. And the first and second
As shown in the figure, uneven parts 20, 20 are formed on the pressure contact parts 19, 19 on both the rear surfaces of the tips of the fixed lever 5 and the operating lever 7, and the uneven parts 20, 20
When the levers 5 and 7 are expanded and pressed against the casting, the pressure contact portions 19 and 19 become difficult to slip. Further, a protrusion 21 is provided at one end of the operating lever 7, and a limit switch 22 is attached to the connecting pipe 3 at a position opposite to the protrusion 21, which operates when the operating lever 7 is closed. It is something that exists. On the other hand, the connecting pipe 3 is inclined upward from the suspension point 23 of the rope 2, and a handle post 25 of the operating section 24 is attached to the upper part of the connecting pipe 3 so as to be movable in the vertical direction. , left and right handles 26, 26 are fixed to both sides of the handle post 25, and the handle 2
Left and right hand grips 27 and 28 are attached to the left hand grips 27 and 26, respectively, and a hydraulic pump (not shown) switch 29 is attached to the left hand grip 27, and while the switch 29 is pressed, the switch 29 is turned on. When the hydraulic pump is in operation and the worker leaves his/her post, when the switch 29 is released, the hydraulic pump is stopped after a certain period of time. A hydraulic oil filling switch 30 for filling hydraulic oil into the hydraulic cylinder 12 is attached to the right-hand grip portion 28, and when the switch 30 is pressed, the operating lever 7 moves to the second position.
When the switch 30 is released, the operating lever 7 is closed as shown by the solid line, and the protrusion 21 of the operating lever 7 comes into contact with the limit switch 22. As a result, the circuit has been changed to one that directly returns the hydraulic oil discharged from the hydraulic pump to the hydraulic oil tank, thereby avoiding wasteful consumption as much as possible. Further, in the above explanation, when the operating lever 7 is expanded, the unnecessary part 60 of the casting is broken and removed, but on the contrary, when the operating lever 7 is closed, the unnecessary part 60 of the casting is broken and removed. It may be removed, in which case the pressure welding part 19,1
It goes without saying that 9 is formed on the opposing inner surfaces of the fixed lever 5 and the operating lever 7.

Note that the hydraulic cylinder 12 and the piston 1
5 and rod 16 constitute the "driving means" of this invention.
