A fixing nut member formed with a locked portion, a substantially disc-shaped locking member, and a joint opening into which the locking member is inserted and locked to the locked portion. And a fixing member having a stop portion, and a large-diameter inner screw portion of the fixing nut member is screwed and fixed to an outer screw portion of the shaft rod, and the locking member is first fixed to a shaft end portion of the shaft rod. The fixing member is formed on the fixture while the locking portion of the fixture is locked to the locked portion of the fixing nut member while the locking member is fixed to the locking opening of the fixing nut member. The mounting hole is aligned with a small-diameter inner screw portion formed in the fixed nut member so as to be fixed by a second fixing tool, The locking member and the fixture are aligned, and in this state, the locking member and the mounting tool are detached from the outer casing body, and the locking member and the mounting tool are fixed by welding, The above-described problem has been solved by adopting a method for assembling the shaft rod locking device in which the fixture is fixed to the fixing nut member with a second fixing tool.

請求項1の発明では、軸杆の緩み止を極めて簡単な構成で且つコンパクトにまとめることができ、しかも緩みを確実にすることができる。また、軸杆緩み止装置の塗装仕上げを極めて良好にすることができる。上記効果を詳述すると、軸杆は、その軸端部に外螺子部が形成されており、該外螺子部に固定ナット部材の大径内螺子部が螺合され、外螺子部と固定ナット部材との螺合によって、軸杆が外筺本体にまず固定される。軸杆の軸方向において、前記外螺子部が形成されている側とは、反対側にフランジ状に形成された軸終端部が形成されているので、軸杆の軸方向一方側にのみ固定ナット部材を螺合することによって、締め付けることができる。   According to the first aspect of the present invention, the locking of the shaft rod can be made compact with a very simple structure, and the loosening can be ensured. In addition, the paint finish of the shaft rod locking device can be made extremely good. The above-mentioned effect will be described in detail. The shaft rod has an outer screw portion formed at the shaft end portion, and the outer screw portion and the fixing nut are screwed into the large-diameter inner screw portion of the fixing nut member. The shaft rod is first fixed to the outer casing main body by screwing with the member. In the axial direction of the shaft rod, since the shaft terminal portion formed in a flange shape is formed on the opposite side to the side on which the external screw portion is formed, a fixing nut is provided only on one axial side of the shaft rod. It can be tightened by screwing the members together.

上記の状態で、前記緩み止部材を前記軸杆の軸端面にボルト等の第1固着具により固着し、軸杆と緩み止部材とを一体化させ、該緩み止部材を取付具の接合用開口部に収納すると共に、前記取付具の係止部を前記固定ナット部材の被係止部に係止する。さらに、前記取付具の取付孔を前記固定ナット部材の小径内螺子部の位置に一致させ、溶接して一体化すると共に、第2固着具を前記取付孔に通して、前記小径内螺子部に螺合締付し、前記取付具を前記固定ナット部材に固着することによって、取付具と緩み止部材とを一体化させ、軸杆に対して最適な緩み止装置とすることができる。このように、適正に一体化された取付具と緩み止部材によって、優れた防御及び防塵の役目をなすカバー材としての役目をなすものである。さらに、一旦、適正な状態で一体化された取付具と緩み止部材は、カバー材として、前記軸杆から外しても、再度軸杆の緩み止めとして装着するときには、常に適正な位置にて装着することができ、分解作業等の保守管理を容易に行うことができる。   In the above state, the locking member is fixed to the shaft end surface of the shaft rod by a first fixing tool such as a bolt, and the shaft rod and the locking member are integrated, and the locking member is used for joining the fixture. While being accommodated in the opening, the locking portion of the fixture is locked to the locked portion of the fixing nut member. Further, the mounting hole of the mounting tool is made to coincide with the position of the small-diameter inner screw portion of the fixing nut member and integrated by welding, and the second fixing tool is passed through the mounting hole to the small-diameter inner screw portion. By fastening by screwing and fixing the fixture to the fixing nut member, the fixture and the locking member can be integrated to provide an optimal locking device for the shaft rod. In this manner, the properly integrated fixture and the locking member serve as a cover material that provides excellent defense and dust protection. Furthermore, once the fitting and the locking member that are integrated in a proper state are removed from the shaft as a cover material, they are always mounted in the correct position when they are mounted again as a locking stop. Therefore, maintenance management such as disassembly work can be easily performed.

また、前記取付具と緩み止部材とを溶接固着して一体化させた後に塗装を行うことにより良好な塗装済表面とすることができる。さらに取付具と緩み止部材のみを溶接することによって、溶接する範囲が小さくなり、溶接作業の高熱等にて侵されることを回避しつつ組付効率を良好にすることができる。   Moreover, it can be set as the favorable painted surface by coating after the said fixture and a locking member are integrated by welding fixation. Further, by welding only the fixture and the locking member, the welding range is reduced, and the assembly efficiency can be improved while avoiding being attacked by high heat or the like of the welding operation.

上述したように、前記取付具は、前記緩み止部材を接合用開口部に収容して、位置合わせを行った後、緩み止部材と取付具とを溶接にて固着するものであり、取付具が外筺本体に固着される構造としたものではない。そのために取付具は、比較的小型で、具体的には直径を極めて小さくすることができる環状円板であり、軸杆の緩み止装置全体を極めてコンパクトな構成にすることができる。また、製造時における組付で取付具と緩み止部材とを溶接にて固着すれば、その後は単に、ボルト等の第1及び第2固着具を着脱するのみの極めて簡単な作業で、軸杆の緩み止構成の分解ができるという優れた利点もある。   As described above, the fixture is configured to fix the looseness prevention member and the fixture by welding after accommodating the looseness prevention member in the joint opening and performing alignment. Is not a structure that is fixed to the outer casing body. Therefore, the fixture is an annular disk that is relatively small in size and specifically capable of having an extremely small diameter, and the entire locking device for the shaft rod can be made extremely compact. Further, if the fixture and the locking member are fixed by welding in the assembly at the time of manufacture, the shaft rod can be easily operated by simply attaching and detaching the first and second fixing tools such as bolts thereafter. There is also an excellent advantage that the loosening prevention structure can be disassembled.

請求項2の発明では、前記外筺本体の前記軸杆支持箇所で且つ前記外螺子部箇所の周囲には、前記取付具が収納される凹部が形成されることにより、取付具が外筺本体の側板から突出することなく、破砕工事等の建設作業において邪魔になるものがなく、良好な作業ができる。請求項3の発明では、前記係止部は突起部として形成され、前記被係止部は前記固定ナット部材の外周に形成された切欠状部として形成された構成によって、固定ナット部材と取付具との係止構造を最も簡単にすることができ、且つ係止を行い易くすることができる。   According to a second aspect of the present invention, a concave portion for accommodating the fitting is formed at the shaft rod supporting portion of the outer rod main body and around the outer screw portion portion, so that the fitting is made of the outer rod main body. Without projecting from the side plate, there is no obstacle in construction work such as crushing work, and a good work can be performed. According to a third aspect of the present invention, the locking portion is formed as a protruding portion, and the locked portion is formed as a notch-shaped portion formed on the outer periphery of the fixing nut member. And the locking structure can be simplified most easily.

次に、請求項4においては、前記軸杆の外螺子部に前記固定ナット部材の内螺子部を螺合固着し、前記緩み止部材を前記軸杆の軸端部にボルト等の第1固着具により固着し、前記緩み止部材を前記接合用開口部に挿入させつつ、前記取付具に形成した取付孔を、前記固定ナット部材に形成した小径内螺子部に位置を合わせて第2固着具により固着し、次いで前記緩み止部材と取付具とを溶接固着する組付方法である。   According to a fourth aspect of the present invention, the inner screw portion of the fixing nut member is screwed and fixed to the outer screw portion of the shaft rod, and the locking member is fixed to the shaft end portion of the shaft rod by a first fixing such as a bolt. The second fixing tool is fixed by a tool, and the mounting hole formed in the mounting tool is aligned with the small-diameter inner screw part formed in the fixing nut member while the locking member is inserted into the joining opening. It is an assembly method in which the loosening prevention member and the fixture are fixed by welding.

この方法によって、固定ナット部材によって軸杆を外筺本体に固定し緩み止部材を軸杆の軸端面にボルト等の第1固着具にて固着し、取付具の係止部を前記固定ナット部材の被係止部に係止することによって、軸杆を最も良好な状態で締め付けた固定ナット部材に対して取付具の取付孔と固定ナット部材の螺子孔との位置合わせを行うことができ、さらに緩み止部材と取付具とを溶接にて固着することで、最も効率的に軸杆の緩み止装置の組付を行うことができる。しかも、その緩み止装置の各部材による締め付けを最良の状態にし、溶着箇所を塗装することにより、良質仕上げができ、ひいては枢支部分の仕上がりを優れたものにできる。   By this method, the shaft rod is fixed to the outer rod main body by the fixing nut member, the locking member is fixed to the shaft end surface of the shaft rod by the first fixing tool such as a bolt, and the locking portion of the fixture is fixed to the fixing nut member. By locking to the locked portion, the mounting hole of the fixture and the screw hole of the fixing nut member can be aligned with respect to the fixing nut member that has tightened the shaft rod in the best condition. Further, by fixing the locking member and the fixture by welding, the shaft rod locking device can be most efficiently assembled. In addition, by tightening with the respective members of the locking device in the best condition and painting the welded portion, a good quality finish can be achieved, and the finish of the pivotal support portion can be made excellent.

請求項5の発明では、緩み止部材と取付具とを、位置合わせしてから、一旦、外筺本体から外して、外筺本体とは異なる場所で緩み止部材と取付具とを溶接するので、溶接による高熱が外筺本体には全く伝わることがなく、外筺本体,軸杆及び固定ナット部材等に熱歪が生じないものにでき、緩み止装置を良好な仕上がりにすることができる。   In the invention of claim 5, since the locking member and the fixture are aligned, then once removed from the outer casing main body, the locking member and the mounting tool are welded at a place different from the outer casing main body. High heat due to welding is not transmitted to the outer casing main body at all, and thermal distortion is not generated in the outer casing main body, the shaft cage, the fixing nut member, etc., and the anti-loosening device can be finished well.
