Description
Technical field
The present invention relates to bridge field, specifically a kind of sling of suspension bridge Suo Li intelligent controlling device.
Background technique
In recent years, the Bridge Design in China and building technology have horizontally entered into advanced ranks in the world.But also occur some
Problem, sling of suspension bridge structure durability and security facing deficiency are exactly one of them.Many suspension bridges are several after completion
Year or more than ten years will change hoist cable, this, which is not only directly consumed, largely changes rope expense and it is necessary to which Yao Shihang traffic control is reduced
The volume of traffic even close traffic, this seriously affects its service level for the large bridge in operation, will cause very big warp
Ji loss, it is serious to generate baneful influence to society.So sling of suspension bridge durability and safety deficiency problem must draw
Play enough attention.
Hanging cable force extremely is to cause hoist cable damage down to one of an important factor for replacement.Theoretically, in design process
In the stress distribution of each hoist cable be reasonable, but every hoist cable is caused due to construction, material, temperature etc. in practice
The Suo Li of carrying can not be identical with theoretical value.It often will appear stress concentration, a certain or a few hoist cables carryings
The king-sized situation of Suo Li.And then the hoist cable fatigue fracture for causing stress to be concentrated, and hoist cable is in case of fracture, and it is remaining
Stress redistribution phenomenon will occur for hoist cable, this will lead to or accelerate the destruction of remaining hoist cable.
Summary of the invention
In order to maintain each hoist cable carrying Suo Li of suspension bridge in the reasonable scope, prevent from hanging caused by concentrating due to stress
Rope damage, the present invention provide a kind of sling of suspension bridge Suo Li intelligent controlling device, can automatically judge hoist cable stress condition, intelligence
Cable force is respectively hung in ground adjustment, the service life for significantly improving hoist cable stress in use, improving hoist cable, simultaneously
It operates very easy, reliable.Concrete scheme of the invention is as follows to achieve the above object.
A kind of sling of suspension bridge Suo Li intelligent controlling device, comprising: electric drive hydraulic thruster, pressure sensor, computer；Institute
Computer is stated to be connected between the electric drive hydraulic thruster and the pressure sensor by conducting wire.
It is characterized by: electric drive hydraulic thruster is connect with a pedestal on bridge floor, multiple pressure sensors are fixed on by nut
On electric drive hydraulic thruster, the push rod of hoist cable and electric drive hydraulic thruster is connected.
Pressure sensor is by the Suo Li of conducting wire Real-time Feedback hoist cable to computer.
When pressure sensor feedback is when hanging cable force less than specified Suo Li range, it is electronic to pass through polygon control survey by computer
The push rod of hydraulic push rod retracts, and makes to hang within the scope of cable force to specified Suo Li.When the cable force that hangs of pressure sensor feedback is greater than
When specified Suo Li range, is released by computer by the push rod of polygon control survey electric drive hydraulic thruster, make to hang cable force to specified rope
Within the scope of power.
Bridge floor is equipped with multiple sling of suspension bridge Suo Li intelligent controlling devices, and entire bridge sling Suo Li is made to be constantly in volume
Determine in range.
Beneficial effects of the present invention are as follows.
One, all movements of the present invention, which are executed, realizes automatic control by computer program, completes people by mechanical device
The impossible work of power, alleviates the labor intensity of people.
Two, the present invention can in real time, comprehensively control and hang cable force, to ensure that its rope force value is in safe rated range
It is interior, improve the safety of suspension bridge.
Three, application of the invention can be such that bridge sling service life effectively extends, and reduce maintenance, replacement hoist cable number, mention
The economic benefit of high suspension bridge.
