(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 connecting pipe 3 suspended from the lower end of a rope 2 whose upper end is connected to a gravity balancer (not shown). 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 rotatably attached 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 the swing shaft 1 of the trunnion 10 holding the cylinder cover 9 is attached to the tips of the brackets 8, 8.
1 and 11 are pivotally mounted to be able to swing freely, a hydraulic cylinder 12 is screwed into the cylinder cover 9, and a hydraulic hose 13,
13 is connected, and the hydraulic hoses 13, 13 pass through the connecting pipe 3 from the lower opening 14 of the connecting pipe 3, and are connected to the hydraulic pump (not shown) from the upper opening (not shown). Yes, 3rd
As shown in the figure, a piston 15 and a rod 16 are installed inside the hydraulic cylinder 12 facing toward the operating lever 7, and the rod 16
An actuating tool 17 is screwed to the tip of the actuating lever 7, and the actuating tool 17 is slidably connected to an actuating pin 18 attached to the inside of the actuating lever 7. As shown in FIGS. 1 and 2, the fixed lever 5
and pressure contact portions 19 on both rear surfaces of the tip of the operating lever 7,
19 is formed with concave and convex portions 20, 20, and when both levers 5, 7 are expanded and press-welded to the casting, the press-contact portions 19, 19
This makes it less slippery. 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 provided so as to be inclined upward from the suspension point 23 of the rope 2, and an operating section 2 is provided at the upper part of the connecting pipe 3.
A handle post 25 of No. 4 is attached to be movable in the vertical direction, and left and right handles 26, 26 are fixed to both sides of the handle post 25, and left and right grip portions 27, 28 are attached to the handles 26, 26.
are attached to each, and the left hand grip part 2
A switch 29 for a hydraulic pump (not shown) is attached to 7, and while the switch 29 is pressed, the hydraulic pump operates, and when the worker leaves his/her post, etc., the switch 29 is turned on. When released, the hydraulic pump will stop 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, hydraulic oil is filled into the hydraulic cylinder 12. The actuating lever 7 is expanded as shown by the dashed line in FIG. be moved. When the switch 30 is released, the operating lever 7 is closed as shown by the solid line, and the projection 21 of the operating lever 7 comes into contact with the limit switch 22, and as a result, hydraulic oil is discharged from the hydraulic pump. The circuit has been changed to one that returns the oil directly to the hydraulic oil pump, in order to avoid 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 goes without saying that the pressure contact portions 19, 19 may be removed, and in that case, the pressure contact portions 19, 19 will be formed on the opposing inner surfaces of the fixed lever 5 and the operating lever 7.
