Description
Technical field
The present invention relates to Hydraulic Metal monitoring technical fields, in particular to a kind of Miter Lock Gates door body horizontal position
The method of real-time of jump.
Background technique
Miter Lock Gates are one of the critical facilities of dealing ship upstream and downstream navigation, are undertaken to long-time high load capacity a large amount of logical
Boat task, is opened and closed repeatedly and during charge and discharge water in miter gate, due to by water impact, underwater pressure change and door body metal
The comprehensive function of the factors such as chemical attack, so that irreversible structural damage occurs in miter gate's door body, and then it is hidden to generate safety
Suffer from.Existing detection method is periodically to suspend ship lock, expends a large amount of manpower and material resources and is manually overhauled, this method is not
Normal shipping transport is only influenced, there is also the possibility of missing inspection, it is most important that can not know within prolonged non-turn(a)round
The healthy operating status of current Miter Lock Gates is found the problem early it is therefore necessary to carry out real-time monitoring to miter gate, and and
Shi Jinhang maintenance.
Miter gate causes door body inevitably to be ground due to up to a hundred tons of weight and a large amount of opening and closings repeatedly itself
Damage, and abrasion embodies a concentrated reflection of at the door-hinge mushroom head of miter gate bottom, so the wear condition monitoring to mushroom head becomes people
One of the important topic of word door operation health status monitoring.But mushroom head is in the position of the lower tens meters of depths of miter gate's bottom water
On, contact surface easy to wear is in the state of closure at work, is difficult directly through existing direct surveillance or three-dimensional structure
Measuring technique observes the current degree of wear.But because miter gate's door body can approximation regard a huge rigid body, door-hinge mushroom as
The variation of door body horizontal position, generates during the abrasion of head and the structural damage of door body itself necessarily bring miter gate to be opened and closed
The jump at inclination angle relative to horizontal direction, so the jump of real-time monitoring miter gate's door body horizontal position can be used as a weight
Index is wanted to measure indirectly to miter gate's health status, and traditional method based on vibration calculating position hopping is because of interference
Multipole is easily distorted, and data volume is huge, can not really reflect the transitional states when front door body, is not suitable for miter gate's jump
Monitoring, so the relevant technologies for being badly in need of a kind of maturation carry out real-time measurement for the horizontal jump of miter gate position.
