APPARATUS FOR PUTTING STEEL PIPE INTO GOOD CONDITION AND APPARATUS AND METHOD FOR DETERMINING TYPE OF STEEL PIPE CLAMP

摘要

SUMMARY OF THE INVENTION An object of the present invention is to provide a maintenance apparatus that can efficiently and efficiently perform screw maintenance of a steel pipe clamp bolt.;Another object of the present invention is to make it possible to discriminate the types of orthogonal clamps and free clamps during maintenance of the steel pipe clamps, thereby enabling automatic classification after maintenance, and to distinguish between orthogonal clamps and free clamps. It is an object of the present invention to provide a type discriminating device for steel pipe clamps, which makes it unnecessary to perform separate work.;For this purpose, the conveying mechanism 11 for conveying the steel pipe clamp 3 supplied to the receiving side to the take-out side and making the posture of the steel pipe clamp 3 constant at the take-out side and the steel pipe clamp 3 with a metal core To supply the metal core of the maintenance mechanism 12 with the maintenance mechanism 12 for straightening the bolts, correcting the two parts of the bolt and applying oil to the bolts, and the steel pipe clamp 3 on the transfer mechanism 11. It consists of the mechanism 13, and automatically performs oil refining of the bolt of the steel pipe clamp 3, straightening of a bifurcation part, and a bolt.;For this and other purposes, the steel pipe clamp 201 moves freely to the chuck mechanism 225 that lifts the steel pipe clamp 201 by holding one clamp unit 202, and moves up to the chuck mechanism 225. The steel pipe clamp 201 determines whether the steel pipe clamp 201 is an orthogonal clamp or a free clamp, depending on whether or not the bolt 208 of the other clamp unit 203 is moved upward. The discriminating apparatus 236 which detects is provided, and it becomes possible to perform classification after maintenance of the steel pipe clamp 201 automatically.
