く迅速に伸縮できる効果がある。 In the figure, reference numeral 6 denotes an auxiliary workbench, which is guided by guiding mechanisms provided on both sides of the workbench 4 and has a structure that allows it to expand and contract left and right. 9 is a telescopic hydraulic cylinder, and its piston rod 10 is connected to a pin 11.
It is pivotally connected to one end of the auxiliary workbench 6 by. 1
Reference numeral 2 denotes a cylinder tube of the telescopic hydraulic cylinder 9. The cylinder tube 12 slides and expands on the support member 13 of the auxiliary workbench 6, and sprocket wheels 14 and 15 are connected to the pin 1 on both sides of the cylinder tube 12, respectively.
6 and 17, it is rotatably connected. The sprocket wheel 14 has one end attached to a pivot point 18 on the auxiliary workbench 6 and the other end attached to a pivot point 19 on the lower part of the workbench 4.
A roller chain 20 is wound around the sprocket wheel 15, and the sprocket wheel 15 has a roller chain 23 connected at one end to a pivot point 21 of the auxiliary workbench 6 and at the other end to a pivot point 22 at the bottom of the workbench. is being wound. The telescopic hydraulic cylinder 9 expands and contracts within the auxiliary workbench, and the telescopic stroke is doubled, so the width of the notch is larger than the width of the workbench, and the gap created is large. This also has the effect of allowing the auxiliary workbench 6 to be moved laterally and laterally with respect to the workbench 4 by a large amount and quickly expanded and contracted.
