Rapid turnover device for end socket

Abstract

The invention discloses a rapid end socket turnover device, and belongs to the technical field of pressure vessel production tools. The sealing head overturning device comprises a base and a sealing head overturning frame, the end socket overturning frame is rotationally mounted on the base, a plurality of clamping mechanisms for clamping and fixing the end socket are mounted on the end socket overturning frame in the circumferential direction of the end socket, and a transmission mechanism for overturning the end socket is mounted between the end socket overturning frame and the base; the clamping mechanism comprises a mounting seat mounted on the seal head roll-over stand, an upper locking arm and a lower locking arm which can clamp the seal head are mounted on the mounting seat, and the upper locking arm is downwards provided with a limiting clamping groove matched with the end of the seal head and an upper locking supporting arm matched with the inner side wall of the seal head. And the lower locking arm is upwards provided with a lower locking support arm matched with the outer side wall of the sealing head. The sealing head clamping device has the beneficial effects that a sealing head clamping and grabbing mode is adopted, welding of lifting lugs and the like is not needed, indentation cannot be caused to the sealing head, the periphery of the whole sealing head is evenly stressed, and the deformation amount of the sealing head is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of production tooling for pressure vessels, in particular to a quick-turning device for a head. Background technique [0002] In the production process of pressure vessel products, the combination of head and cylinder is very important for assembly. The traditional head assembly needs to use the crane to hoist the head, and the head needs to be welded with the lifting lugs in advance. The head is the main pressure component, and the welding lugs are cut again, which increases the risk of welding defects in the head. At the same time, the welding heat input will also cause deformation of the head. The inside and outside of the head need to be backed up, However, due to the limitation of the shape of the head, it is very inconvenient to turn the head over, and the hoisting jig can easily cause crush damage to the head in the traditional production process. SUMMARY OF THE INVENTION [0003] The technical pr...

The head is the main pressure component, and the welding lugs are then cut, which increases the risk of welding defects of the head. At the same time, the welding heat input will also cause deformation of the head. The inside and outside of the head need to be correspondingly backed, Welding of the rib plate, but due to the limitation of the shape of the head, it is inconvenient to turn the head over, and the lifting fixture in the traditional production process is easy to cause crush damage to the head
