End post structure assembling tool and rigid water stop miter gate manufacturing method

Abstract

The invention discloses an end post structure assembling tool and a rigid water stop miter gate manufacturing method. By the adoption of a method of joint assembling of two adjacent single-section gate leaves, assembling of single-section gate leaf structures is performed, so that deviations such as slab staggering, dislocation and the like at the section positions of the gate leaves are avoided; by the adoption of the suspended overturning technology, a workpiece is overturned in the air after being hoisted away from the ground, structural deformation and potential safety hazards caused by hoisting impact are eliminated, the optimal flat welding position is provided for welding, vertical position welding and overhead position welding are changed into flat welding, and the welding quality and the welding efficiency are improved; a space coordinate system is established on a single gate leaf structure, the dimensional precision of each part is accurately controlled through coordinate values, and particularly, the coaxiality of the centers of a top pivot and a bottom pivot and the assembly precision of supporting and pillow cushion blocks are controlled, so that the measurement control becomes more accurate, simpler and more convenient; and a centering and positioning device is arranged at the segmented position of the gate leaf structure, so that construction site installation and in-place are more accurate and rapid.

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...
