Description

Technical Field

[0001] The invention relates to a device and method for measuring the vertical line of the geometric shape of a ship lock miter gate, and belongs to the field of vertical line data measurement of the geometric shape of a large ship lock miter gate. Background Art

[0002] Miter gates are crucial operating equipment for ship locks. When closed, they block upstream water and withstand the hydraulic pressure created by the water level difference between upstream and downstream. When open, ships can enter and exit the lock.

[0003] The vertical lines of a miter door's geometry reflect its posture. These values ​​must be adjusted to a reasonable range during installation and after the top door is lowered after maintenance. Existing methods for measuring these values ​​involve welding two φ16×200mm round steel bars to the front and side of the top of the miter post. Based on the technical requirements for measuring these values, technicians use a hammer to tap the welded round steel bars to adjust them to the appropriate angle. Then, using a steel ruler, measurements are taken from the top of the miter post to the bottom every 3 meters, in both the fully closed and fully open positions. This method requires multiple personnel to install and remove the welded round steel bars, which requires high-altitude edge detection, bottom inspection, and installation and removal. This results in lengthy installation and adjustment times, high investment in manpower and equipment resources, and low efficiency, posing a significant safety risk. Summary of the Invention
