しかしながら、回転ロックのために必要な力から計算される油圧シリンダーの内径より、油圧シリンダーが収められる中空部の径が大きくなるから、コンパクト化に限界があるという問題がある。 However, since the diameter of the hollow portion in which the hydraulic cylinder is accommodated is larger than the inner diameter of the hydraulic cylinder calculated from the force required for rotation lock, there is a problem that there is a limit to downsizing.

本発明は以上の従来技術における問題に鑑みてなされたものであって、杭圧入機の回転ロック装置のコンパクト化を図ることを課題とする。   This invention is made | formed in view of the problem in the above prior art, Comprising: It aims at achieving compactization of the rotation lock apparatus of a pile press-fit machine.

以上の課題を解決するための請求項１記載の発明は、杭圧入機の回転するマスト又は杭チャック装置である回転部の当該回転をロックする回転ロック装置であって、
前記回転部及び当該回転部を回転支持する支持部の一方に固定され前記回転の軸に同軸に配置されたフランジ状のプレートと、
前記回転部及び当該回転部を回転支持する支持部の他方に固定された筐体及び油圧により前記プレートを押圧するピストンを持ち、前記プレートを把持する把持装置と、を備え、
前記筐体には、前記プレートを受け入れる前記回転の径方向に抉り込まれた溝部と、前記溝部の側面に開口し前記ピストンが当該開口から突出して前記回転の軸に平行な方向に進退可能に挿入される円柱状中空部とが形成され、
前記把持装置は、前記円柱状中空部に内接する前記ピストンに前記円柱状中空部の断面積分の油圧を負荷可能に構成されたことを特徴とする杭圧入機の回転ロック装置である。 Invention of Claim 1 for solving the above subject is a rotation lock device which locks the rotation of the rotation part which is a mast or a pile chuck device which a pile press-in machine rotates,
A flange-like plate that is fixed to one of the rotating part and a support part that rotatably supports the rotating part and is arranged coaxially with the axis of rotation;
A housing fixed to the other of the rotating part and the support part that rotatably supports the rotating part, a piston that presses the plate by hydraulic pressure, and a gripping device that grips the plate,
The casing receives the plate and has a groove that is swung in in the radial direction of rotation, and opens on a side surface of the groove, so that the piston protrudes from the opening and can advance and retreat in a direction parallel to the axis of rotation. A cylindrical hollow portion to be inserted is formed,
The gripping device is a rotation locking device of a pile press-fit machine, wherein the piston inscribed in the cylindrical hollow portion is configured to be able to apply a hydraulic pressure of a cross-sectional integral of the cylindrical hollow portion.

本発明によれば、回転部の回転のロックのために把持されるプレートを受け入れる溝部と、ピストンを収める円柱状中空部とが一つの筐体に形成され、この筐体にピストンを組み込めば油圧シリンダーを構成することができるとともに、ピストンには円柱状中空部の断面積分の油圧を負荷可能であるので、回転ロックのために必要な力から計算される油圧シリンダーの内径は、円柱状中空部の内径と等しくなり、杭圧入機の回転ロック装置のコンパクト化を図ることができる。   According to the present invention, the groove portion that receives the plate to be gripped for locking the rotation of the rotating portion and the cylindrical hollow portion that accommodates the piston are formed in one housing, and if the piston is incorporated in this housing, the hydraulic pressure is increased. Since the cylinder can be configured and the piston can be loaded with the hydraulic pressure of the cross-sectional integral of the cylindrical hollow part, the inner diameter of the hydraulic cylinder calculated from the force required for rotation lock is the cylindrical hollow part Therefore, it is possible to make the rotary lock device of the pile press-fitting machine compact.

以下に本発明の一実施形態につき図面を参照して説明する。以下は本発明の一実施形態であって本発明を限定するものではない。   An embodiment of the present invention will be described below with reference to the drawings. The following is one embodiment of the present invention and does not limit the present invention.

図１に示す杭圧入引抜機１００に、本実施形態の回転ロック装置１０７が搭載されている。杭圧入引抜機１００は、作業を行うためにスライドベース１０１に対しマスト１０２が回転動作でき、マスト１０２に支持された昇降部１０３に対し杭チャック装置１０４が回転動作できる。杭チャック装置１０４は、圧入する杭を掴むためのものである。マスト１０２の回転軸１０５及び杭チャック装置１０４の回転軸１０６は垂直方向であり、それぞれ水平回転する。
マスト１０２は回転部に相当し、スライドベース１０１は当該回転部を回転支持する支持部に相当する。杭チャック装置１０４は回転部に相当し、昇降部１０３は当該回転部を回転支持する支持部に相当する。
このマスト１０２や杭チャック装置１０４の回転をロックするために回転ロック装置が適用される。その構造は同様であるため、杭チャック装置１０４の回転をロックする回転ロック装置１０７を例に説明する。 A rotation locking device 107 according to this embodiment is mounted on the pile press-fitting and drawing machine 100 shown in FIG. In the pile press-fitting and extracting machine 100, the mast 102 can rotate with respect to the slide base 101 in order to perform the work, and the pile chuck device 104 can rotate with respect to the elevating part 103 supported by the mast 102. The pile chuck device 104 is for grasping a pile to be press-fitted. The rotating shaft 105 of the mast 102 and the rotating shaft 106 of the pile chuck device 104 are in the vertical direction and rotate horizontally.
The mast 102 corresponds to a rotating portion, and the slide base 101 corresponds to a support portion that supports the rotating portion in rotation. The pile chuck device 104 corresponds to a rotating unit, and the elevating unit 103 corresponds to a support unit that rotatably supports the rotating unit.
A rotation lock device is applied to lock the rotation of the mast 102 and the pile chuck device 104. Since the structure is the same, the rotation lock device 107 that locks the rotation of the pile chuck device 104 will be described as an example.

図２に示すように回転ロック装置１０７は、把持装置１と、ロックプレート２とを備える。
ロックプレート２は、回転部である杭チャック装置１０４に固定され、回転軸１０６と同軸に配置されたフランジ状の部材である。すなわち、杭チャック装置１０４の回転とともにロックプレート２が回転軸１０６回りに一体回転する。
把持装置１は、支持部である昇降部１０３に固定されている。図２に示すように把持装置１には回転軸１０６の径方向に抉り込まれた溝部１１が形成されており、溝部１１にロックプレート２を受け入れる。 As shown in FIG. 2, the rotation lock device 107 includes a gripping device 1 and a lock plate 2.
The lock plate 2 is a flange-shaped member that is fixed to the pile chuck device 104 that is a rotating portion and is arranged coaxially with the rotating shaft 106. That is, the lock plate 2 rotates integrally around the rotation shaft 106 with the rotation of the pile chuck device 104.
The gripping device 1 is fixed to an elevating unit 103 that is a support unit. As shown in FIG. 2, the gripping device 1 is formed with a groove 11 that is sunk in the radial direction of the rotary shaft 106, and receives the lock plate 2 in the groove 11.

図３に示すように把持装置１は、筐体１０と、ピストン２０と、ヘッドブロック３０とを有する。
筐体１０に、上述した溝部１１が形成されており、さらに円柱状中空部１２，１２が形成されている。また、把持装置１は、筐体１０に形成された固定フランジ部１３，１３で締結されて昇降部１０３に固定される。
溝部１１の上方の円柱状中空部１２は、溝部１１の上側の側面１１ａに開口して形成されている。溝部１１の下方の円柱状中空部１２は、溝部１１の下側の側面１１ｂに開口して形成されている。この開口を内側開口と呼ぶ。 As shown in FIG. 3, the gripping device 1 includes a housing 10, a piston 20, and a head block 30.
The groove portion 11 described above is formed in the housing 10, and the cylindrical hollow portions 12 and 12 are further formed. The gripping device 1 is fastened by fixing flange portions 13 and 13 formed in the housing 10 and fixed to the lifting / lowering portion 103.
The cylindrical hollow portion 12 above the groove portion 11 is formed so as to open to the upper side surface 11 a of the groove portion 11. The cylindrical hollow portion 12 below the groove portion 11 is formed to open to the lower side surface 11b of the groove portion 11. This opening is called an inner opening.

円柱状中空部１２に挿入されたピストン２０が内側開口から溝部１１内に突出して回転軸１０６に平行な方向に進退可能にされる。したがって、円柱状中空部１２、１２の軸は回転軸１０６に平行である。円柱状中空部１２、１２は側面１１ａ，１１ｂの反対側にも開口している。この開口を外側開口と呼ぶ。この外側開口からピストン２０は円柱状中空部１２に挿入される。ピストン２０の溝部１１内に突出する量が所定量で規制されるように、円柱状中空部１２及びピストン２０は突出側で小径の段付きで構成されている。組立時にはピストン２０が円柱状中空部１２挿入された後、外側開口にヘッドブロック３０が嵌合固定される。   The piston 20 inserted into the cylindrical hollow portion 12 protrudes into the groove portion 11 from the inner opening, and can advance and retreat in a direction parallel to the rotation shaft 106. Accordingly, the axes of the cylindrical hollow portions 12 and 12 are parallel to the rotation axis 106. The cylindrical hollow portions 12 and 12 are also opened on the opposite sides of the side surfaces 11a and 11b. This opening is called an outer opening. The piston 20 is inserted into the cylindrical hollow portion 12 from this outer opening. The cylindrical hollow portion 12 and the piston 20 are configured with a small-diameter step on the protruding side so that the amount protruding into the groove portion 11 of the piston 20 is regulated by a predetermined amount. At the time of assembly, after the piston 20 is inserted into the cylindrical hollow portion 12, the head block 30 is fitted and fixed to the outer opening.

ヘッドブロック３０に構成された圧油路を介して把持装置１は杭圧入引抜機１００の油圧制御システムに接続される。円柱状中空部１２とピストン２０とヘッドブロック３０とに囲まれた空間に圧油が送り込まれ、円柱状中空部１２に内接するピストン２０に円柱状中空部１２の断面積分の油圧を負荷可能である。この油圧によりピストン２０は突出動作してロックプレート２を押圧し、上下のピストン２０，２０によりロックプレート２を把持する。   The gripping device 1 is connected to the hydraulic control system of the pile press-fitting / pulling machine 100 through a pressure oil passage formed in the head block 30. Pressure oil is fed into a space surrounded by the cylindrical hollow portion 12, the piston 20, and the head block 30, and the piston 20 inscribed in the cylindrical hollow portion 12 can be loaded with the hydraulic pressure of the cross-sectional integral of the cylindrical hollow portion 12. is there. This hydraulic pressure causes the piston 20 to project and press the lock plate 2, and the upper and lower pistons 20, 20 hold the lock plate 2.

以上の本実施形態の杭圧入機の回転ロック装置によれば、ロックプレート２を受け入れる溝部１１と、ピストン２０を収める円柱状中空部１２とが一つの筐体１０に形成され、この筐体１０にピストン２０を組み込めば油圧シリンダーを構成することができる。ピストン２０には円柱状中空部１２の断面積分の油圧を負荷可能であるので、回転ロックのために必要な力から計算される油圧シリンダーの内径は、円柱状中空部１２の内径と等しくなり、杭圧入引抜機１００の回転ロック装置１０７のコンパクト化を図ることができる。
また、昇降部１０３に締結固定され溝部１１が形成された筐体とは別部品としてのシリンダー部品が不要となり、部品点数減による製造コストの低下を図ることができる。 According to the rotary lock device of the pile press-fitting machine of this embodiment described above, the groove portion 11 that receives the lock plate 2 and the cylindrical hollow portion 12 that houses the piston 20 are formed in one housing 10. If the piston 20 is incorporated into the hydraulic cylinder, a hydraulic cylinder can be configured. Since the piston 20 can be loaded with the hydraulic pressure of the cross-sectional integral of the cylindrical hollow portion 12, the inner diameter of the hydraulic cylinder calculated from the force necessary for the rotation lock becomes equal to the inner diameter of the cylindrical hollow portion 12, The rotation lock device 107 of the pile press-fitting and drawing machine 100 can be made compact.
In addition, a cylinder part as a separate part from the casing that is fastened and fixed to the elevating part 103 and formed with the groove part 11 is not necessary, and the manufacturing cost can be reduced by reducing the number of parts.

なお、以上の実施形態においては、把持装置１を支持部に、ロックプレートを回転部に固定したが、逆に把持装置１を回転部に、ロックプレートを支持部に固定しても実施可能である。
また、以上の実施形態においては、溝部１１の上下の双方に進退動作するピストン２０を配置したが、溝部１１の上方又は下方のみに進退動作するピストン２０を配置しても実施可能である。その場合、例えば、図５に示すように固定プレート１４をピストン１２に対向配置して筐体１０に固定設置した形態を実施することが好ましい。この場合、固定プレート１４を交換可能である。 In the above embodiment, the gripping device 1 is fixed to the support portion and the lock plate is fixed to the rotation portion. However, the gripping device 1 may be fixed to the rotation portion and the lock plate may be fixed to the support portion. is there.
Further, in the above embodiment, the piston 20 that moves forward and backward is arranged on both the upper and lower sides of the groove 11, but the present invention can also be implemented by arranging the piston 20 that moves forward and backward only above or below the groove 11. In that case, for example, as shown in FIG. 5, it is preferable to implement a form in which the fixing plate 14 is disposed opposite to the piston 12 and fixed to the housing 10. In this case, the fixed plate 14 can be replaced.
