Assembly tooling of terminal column structure and manufacturing method of rigid water-stop miter gate

Abstract

The invention discloses a method for manufacturing end column structure assembly tooling and a rigid water-stop miter gate. The joint assembly method of two adjacent single-section door leaves is used to assemble the single-section door leaf structure and avoid door leaf division. The position produces deviations such as misalignment and dislocation; the suspension flip technology is used to make the workpiece flip in the air after being lifted off the ground, eliminating structural deformation and safety hazards caused by hoisting impact, and providing the best flat welding position for welding. Vertical welding, Overhead welding is changed to flat welding to improve welding quality and welding efficiency; a spatial coordinate system is established on the single door leaf structure, and the dimensional accuracy of each part is accurately controlled through coordinate values, especially the coaxiality of the top and bottom pivot centers and the support, The assembly accuracy control of the pillow block makes the measurement control more accurate and convenient; the centering positioning device is installed at the segmental position of the door leaf structure to make the installation on the site more accurate and fast.

Description

technical field [0001] The invention relates to the field of manufacturing miter gates of ship lock hinges, and relates to a manufacturing method of end column structure assembly tooling and rigid water-stop miter gates. Background technique [0002] In water transport ship lock hub projects, water miter gates are widely used and are the main metal structural equipment of ship lock hub projects. , The center line of the bottom pivot is the horizontal rotation of the rotation axis to open or close, which meets the intercommunication conditions of upstream and downstream ships. The coaxiality control of the top and bottom pivot centers of the miter gate, and the close contact between the support and the pillow block to realize rigid water-stop are the key points and difficulties in the manufacture of the miter gate. Affected by factors such as the large size and complex structure of the miter gate, the manufacturing process is complicated, the quality control is difficult, an...
