Description
Technical field
The invention belongs to Phase of Electric Power Projects field, more particularly to a kind of iron tower of power transmission line group founds safety automatic-alarming system
System and construction method.
Background technology
In the construction of electric power transmission line tower erection, largely using drawstring outside interior suspension and interior bracing wire pole group tower construction
Method, the main Work tool that this method is used includes pole, pole bracing wire, lifting rope（Including lifting tackle pulley, suspension centre rope, lead
Messenger etc.）, bearing rope and tricing line etc..Instrument Force Calculation should be first by the lift heavy of each time of full tower and corresponding pole inclination angle, control
Angle is combined over the ground for rope making and bracing wire, but special circumstances often occurs in work progress, and such as wind-force is excessive, or rises
Hanging part part is overweight etc. on a small quantity, runs into what the general foundation construction experience of such case was handled.
The content of the invention
The technical solution adopted for the present invention to solve the technical problems is to provide a kind of vertical safety of iron tower of power transmission line group certainly
Dynamic warning system and construction method, when occurring value of thrust during tower erection more than normal value, are then made by alarm, stopping
The modes such as industry, improve the security of tower erection, can also be judged by the value of thrust to different parts, be which locally occurs
Problem, in order to be improved to follow-up tower erection, overcomes the generation of dangerous situation.
The technical scheme is that, a kind of iron tower of power transmission line group founds safety automatic-alarming system, tower erection system
Including basis, on the basis of pole bottom is temporarily fixed at by bearing rope, pole top is temporarily fixed at ground by outer drawstring
On, pole be provided with lifting part, hoisting line one end be fixed on sling on thing, the other end passes through the lifting part and machine on pole
Dynamic to be twisted connection, described warning system includes the pulling force sensor being located on rope, and pulling force sensor passes through wireless network and prison
Control device connection；
The supervising device includes controller and the motor-driven grinding mill switch, phonetic alarm, the lamp that are connected respectively with controller
Light crossing-signal.
Further, pulling force sensor includes bracing wire pulling force sensor, bearing rope pulling force sensor, hoisting line pull sensing
Device, bracing wire pulling force sensor is located on outer drawstring, and bearing rope pulling force sensor is located on bearing rope, and hoisting line pulling force sensor is set
On hoisting line.
Further, warning system also includes anemometry device, on the basis of anemometry device is arranged on, and connects with controller
Connect.
A kind of iron tower of power transmission line group, which founds safe construction method, includes the outer drawstring of collection, bearing rope, lifting rope tension in real time
Data, assessment risk, corrective measure；
Described real-time collection outer drawstring, bearing rope, hoisting line pulling force data, divide on outer drawstring, bearing rope, hoisting line
Pulling force sensor is not set, and the data that pulling force sensor is gathered are collected；
The assessment risk, if the pulling force data on outer drawstring, bearing rope, hoisting line exceeds setting value, shows
Lifting part weight is overweight；If the pulling force data of outer drawstring, bearing rope exceeds setting value, show that extraneous interim dynamic load is external
Drawstring, the influence of bearing rope exceed setting limit；If the pulling force data of outer drawstring exceeds setting value, show that pole sets angle
The influence for spending the bigger than normal or extraneous external drawstring of interim dynamic load exceedes setting limit；If the pulling force data of bearing rope is beyond setting
Value, then show that pole sets angle bigger than normal；If the pulling force data on hoisting line exceeds setting value, show lifting part weight
It is overweight；
The corrective measure, if lifting part weight is overweight, carries out decomposing reduction hoisting weight to lifting part；If
It is that extraneous interim dynamic load exceedes setting limit, suspension of works waits extraneous interim dynamic load to disappear or weaken；If pole is set
Angle is bigger than normal, can be by reducing the weight of lifting part or adjusting few pole to set angle.
Further, safe construction method also includes urgent danger prevention, and the urgent danger prevention in the real-time outer drawstring of collection, is held
During support rope, the pulling force data of hoisting line, if a certain item pulling force data increases too fast, send out an emergency signal, will lift by crane
Part is transferred to ground.
Further, outer drawstring, bearing rope, the pulling force data process of hoisting line are gathered in real time, also gather construction area
Wind data, wind data exceedes after setting value, suspension of works.
It is an advantage of the current invention that the real time measure is carried out by the pulling force to the different parts rope during tower erection,
And pulling force data is handled, whether belonged to according to pulling force data in normal range (NR), can be with to instruct the construction of tower erection
The security of construction is increased substantially, the generation of security incident is reduced.
