Description
Technical field
The present invention relates to Rare Metals Materials field, in particular to a kind of system of efficient, soilless sticking high-purity rhenium powder
Preparation Method.
Background technology
Derrick crane（Abbreviation tower crane）It is a kind of lifting equipment of vertical transport, is widely used in skyscraper, water power
It is a kind of special equipment in the engineering constructions such as engineering, harbour, energy construction, security incident is very prominent.Due to tower crane height
Height, coverage is big, and tower crane driver is frequently encountered some vision dead zones in operation.If tower crane is made in these blind areas
Industry, suspension hook hangs building or the other objects in ground by mistake during raising, and tower crane driver can not realize, it is possible to can occur
It is dangerous.It is light then tower crane lifting wire cable rupture, weight is caused to drop, tower crane steel construction is damaged, heavy then tower crane can be caused to topple, go out
Existing casualties major accident.
The present invention relates to a kind of tower crane suspension hooks to hang automatic protective system by mistake, and system is equipped with the dedicated intelligent controller of tower crane
And display screen, joint action table control instruction, position limitation protection signal, the sensor signal of tower crane can be received, and lifting mechanism is carried out
Control.Suspension hook hangs the operating condition of automatic protective system real time monitoring Lift Mechanism in Power Hoist, weight, height, the amplitude of tower crane by mistake
Etc. sensor signals situation of change, when tower crane suspension hook occur by mistake hang when, there is anomalous variation in the signals such as weight, height, and system exists
Raising suspension hook is diagnosed to be in short time, extension by mistake has occurred, take the brake measure that stops in emergency, and be carried out at the same time alarm, remind driver
Suspension hook occurs to hang by mistake, hangs the security incident triggered by mistake so as to avoid suspension hook.
The content of the invention
It is an object of the present invention to provide a kind of raising suspension hooks based on tower crane intelligentized control method to hang guard method, system by mistake
Monitor the signals such as weight, height, amplitude of tower crane work in real time, and combine the logical datas such as input, output of tower crane operation into
Row comprehensive analysis, and intelligence computation is carried out, and then judge whether tower crane occurs the suspension hook abnormal conditions such as extension by mistake.When appearance misses extension etc.
Abnormal conditions automatically cut off Lift Mechanism in Power Hoist power supply, carry out emergency braking, and alarm.
In order to achieve the above object, the technical solution adopted by the present invention is：It is a kind of that hanging is played based on tower crane intelligentized control method
Hook hangs guard method by mistake, hangs protection system by mistake using suspension hook and tower crane weight signal is monitored, by the process of tower crane lifting point
For three phases, starting stage, weight calculation stages and normal operating phase；This three phases utilizes height sensor acquisition
Lifting height data are as partitioning standards；
Weight calculation stages measure weight signal by using weight sensor, calculate the referential weight of weight；
Operation phase hangs basis for estimation by mistake by the use of weight sensor signal intensity as suspension hook.
Further, idiographic flow is that starting stage, tower crane brings into operation, hoisting heavy, during operation is risen, is hung
Hook low grade microinching, suspension hook is hung by mistake when, tower crane provides load lifting limiter, limiter of moment action for oneself, realizes protection；It rises and hangs
After ground reaches certain altitude, after the starting stage, into weight calculation stages, and memory elemental height is set to, at this point, suspension hook
Lifted weight is completely liftoff, at this point, weight weight is stablized, and rises, measures weight weight by weight sensor, completes ginseng
Weight calculating is examined, hangs the foundation judged by mistake as normal operating phase suspension hook；During this period, in the event of hanging by mistake, if more than weight
The limitation of limiter, limiter of moment is measured, stops braking, declines operation, reenters the starting stage；If it is weighed not less than limitation
Object, which rises, to be stopped, then stopping brake；After the completion of referential weight calculates, record height, and into normal operating phase, if during which
Weight increases without abnormal, but more than the limitation of weight limitor, limiter of moment, then stops braking, and declines operation, if normally
Then reenter the starting stage；If weight is without abnormal increase and the weight rising stopping not less than limitation, directly parking system
It is dynamic；If period gravimetric anomaly increases, then direct stopping brake；Decline operation, the starting stage is reentered if normal.
Further, what referential weight calculated concretely comprises the following steps, and weight weight amount 5-10 is measured by weight sensor
Group, and its average is taken to be used as with reference to weight.
Further, measurement interval is 0.1-0.3s between each group numerical value.
Further, the time cycle that referential weight calculates is 1-2s.
Further, gravimetric anomaly increase refers to, in uphill process, the measured value of weight sensor measurement weight is more than
The permission domain of walker of referential weight.
Further, domain of walker is the 10%-30% for the weight for being played weight；It is determined according to the actual weight of weight.
Beneficial effects of the present invention：Traditional tower crane relies solely on the reality of the weight limitor of itself, limiter of moment etc.
Existing overload protection, reaction is slow, and the response time is long, and when being promoted, torque overload is big；And the system real time monitoring tower crane work
The signals such as weight, height, amplitude, and combine the logical datas such as input, the output of tower crane operation and carry out comprehensive analysis, and carry out intelligence
It can calculate, and then judge whether tower crane occurs the suspension hook abnormal conditions such as extension by mistake, reaction is fast, and precision is high, securely and reliably；When missing
The abnormal conditions such as extension automatically cut off Lift Mechanism in Power Hoist power supply, carry out emergency braking, and alarm.
