Description
本発明は、ケーシング回転圧入装置、杭振動圧入装置等の各種部材を地中に圧入する装置において、重量物の部材圧入作業機構を支持する枠形ベースフレームに関する。 The present invention relates to a frame-type base frame that supports a heavy member press-fitting work mechanism in a device that press-fits various members such as a casing rotary press-fitting device and a pile vibration press-fitting device into the ground.
例えば、縦材と横材を連結してなる矩形枠形の通常のベースフレーム上に、ケーシングを回転させる機構及びケーシングをチャックして間欠的に圧入する機構を搭載してなるケーシング回転圧入装置をトレーラーにのせて輸送する場合上記ベースフレームの左右幅が輸送トレーラーの荷台幅（輸送規定寸法）を超えているため、装置を分解せずにそのままの状態でトレーラーにのせることはできない。 For example, a casing rotary press-fitting device in which a mechanism for rotating a casing and a mechanism for intermittently press-fitting the casing by chucking the casing are mounted on a rectangular base frame formed by connecting vertical and cross members. When transporting on a trailer, the left and right widths of the base frame exceed the loading platform width (transportation stipulated dimensions) of the transport trailer, and therefore cannot be mounted on the trailer without disassembling the device.
そこで、従来、縦材と横材からなる矩形枠形であって、図４（イ）に示すように、縦材（ａ）、（ａ）の両端部側面を横材（ｂ）、（ｂ）の端面に向けた状態で、該縦材（ａ）、（ａ）の側面に突設されたスライドアーム（ｃ）、（ｃ）を横材（ｂ）、（ｂ）内に進退自在に挿入して支持させ、上記縦材（ａ）、（ａ）の両端部にアウトリガー（ｄ）、（ｄ）をそれぞれ取りつけた構造のベースフレームが提案され、これをケーシング回転圧入装置に使用した場合、輸送時には、上記縦材（ａ）、（ａ）を内方へ後退させてベースフレームの横幅を輸送規定寸法以下に縮幅してトレーラー荷台上にのせ、ケーシング圧入施工時には、上記縦材（ａ）、（ａ）を外方へ進出させてベースフレームの横幅を所要の安定幅に拡幅するのである。 Therefore, conventionally, it is a rectangular frame shape composed of a vertical member and a horizontal member, and as shown in FIG. 4 (a), both side surfaces of the vertical members (a) and (a) are connected to the horizontal members (b) and (b ) The slide arms (c) and (c) projecting from the side surfaces of the longitudinal members (a) and (a) can be advanced and retracted into the transverse members (b) and (b) in a state facing the end surface of When a base frame having a structure in which outriggers (d) and (d) are respectively attached to both ends of the longitudinal members (a) and (a) is proposed and used in a casing rotary press-fitting device. During transportation, the vertical members (a) and (a) are retracted inward to reduce the width of the base frame to the transport regulation dimension or less and place it on the trailer bed. a) and (a) are advanced outward to widen the lateral width of the base frame to a required stable width.
しかし、上記のような従来ベースフレームの縦、横材枠組み構造では、ベースフレームの横幅を輸送規定寸法以下に縮小するためには、縦材自体の幅を縮小したり、縮幅縦材の側面に補強材を着脱自在にボルト止めし、輸送時に補強材を分離し、施工時にボルト止めする方法が行われたが、前者は、ベースフレームとしての必要強度を害う難点があり、後者は、補強材の取りつけ、分離に煩わしい作業を要する欠点があった。 However, with the vertical and horizontal frame structure of the conventional base frame as described above, in order to reduce the horizontal width of the base frame to the transport regulation size or less, the width of the vertical member itself or the side surface of the reduced vertical member The method of bolting the reinforcing material in a removable manner, separating the reinforcing material at the time of transportation, and bolting at the time of construction was performed, but the former has a difficulty that impairs the required strength as a base frame, the latter, There was a drawback that a troublesome work was required for attaching and separating the reinforcing material.
本発明は、ベースフレームとしての必要強度を十分に備えると共に、輸送時及び施工時に、従来のような煩わしい作業なしに対応することのできるベースフレームを提供することを課題とする。 An object of the present invention is to provide a base frame that has sufficient strength as a base frame and can cope with the troublesome work of the related art during transportation and construction.
そこで、本発明は、

上記縦材の前後両端に該縦材長手方向と直角にそれぞれ固定された溝付スライド板（１０）、（１０ａ）に、上記横材（９）、（９ａ）の各側面に該横材の長手方向と平行に固定されたスライド案内板（１１）、（１１ａ）を摺動自在に係合すると共に、上記各溝付スライド板（１０）、（１０ａ）に油圧シリンダ（１３）、（１３ａ）の一端を連結し、他端を上記各横材（９）、（９ａ）に連結し、
上記縦材（８）、（８ａ）に、走行板（１７）、（１７ａ）を、該縦材に設けられた縦材長手方向に沿う長孔（１８）、（１８ａ）にそれぞれ貫通されたピン（１９）、（１９ａ）により、該縦材より下に張り出した状態で長孔（１８）、（１８ａ）の長さ範囲で摺動自在に支持すると共に、上記縦材（８）、（８ａ）に油圧シリンダ（２０）、（２０ａ）の一端を連結し、他端を上記走行板（１７）、（１７ａ）にそれぞれ連結し、
上記横材（９）、（９ａ）の各左右両端部に、上記走行板（１７）、（１７ａ）よりも下方へ接地可能のアウトリガーをそれぞれ固定した、
部材圧入作業装置におけるベースフレームを提案する。
