上を自走移動可能としたクランプ機構に関する。Description: TECHNICAL FIELD The present invention relates to a clamp mechanism for a pile press-in / pull-out machine, a crane device, a bucket, a clam shell, and other work equipment on a pile, and each clamp can be removed from a saddle. Thus, the present invention relates to a clamp mechanism that enables self-propelled movement on an existing pile row without moving the pile work device upward.
（従来の技術） 従来の杭上作業装置のクランプ機構はサドル下端に一体
に構成されていて、作業時に各クランプをサドルより取
外すことはできなかった。(Prior Art) The clamp mechanism of the conventional pile work device is integrally formed at the lower end of the saddle, and each clamp cannot be detached from the saddle at the time of work.

杭の上方に持上げて前方に移動していた。When press-fitting a pile with such a pile work device, for example, a pile press-in / pull-out machine, the existing pile is gripped by the clamp fixed to the saddle to obtain a reaction force, and a new pile is gripped and press-fitted. Go. When the pile press-fitting / extracting machine moves forward, the chuck grips the pile during press-fitting, lifts the clamp together with the saddle above the pile, and moves it forward.

ればならなかった。Further, in the pile press-fitting / pulling machine as described above, when the self-propelled movement was performed on the existing pile row, the attachment had to be attached to the chuck.

ため移動できないという欠点があった。(Problems to be Solved by the Invention) As described above, since the conventional clamp mechanism of the pile-up working apparatus is configured integrally with the main body, the apparatus has to be moved up when moving. However, when the distance between the top of the pile and the lower part of the obstacle is limited, such as when working under the bridge, there is a drawback that the device cannot move because it contacts the obstacle when the device is raised.

して継ぐ等の作業も必要であった。Further, if the entire apparatus is moved upward, the position of the center of gravity becomes high and it becomes unstable, which is dangerous. Furthermore, when gripping a pile in the middle of press fitting with soft ground and applying the full weight of the pile press-fitting / pulling machine to this pile, the support force may be insufficient and the pile may not sink and the body may not lift. Work such as welding and connecting to existing piles was also necessary.

ため作業能率が低下する等の問題も生じていた。Since the clamp and saddle are integrated, a crane or a large transport vehicle capable of hoisting the entire device during transportation and unloading is required, and an attachment must be attached to the chuck when moving on the existing pile row. There was also a problem that the work efficiency decreased because it had to be done.
