The utility model provides a kind of technical solution referring to FIG. 1-2,：A kind of cast tube sprays zinc device, including left and right automatically
The symmetrically arranged driving track in two sides, pipe carrying truck 4 before being provided on front side of the driving track in left side, the driving track in left side
Right end be connected with separation device 1, the right end of separation device 1 is connected with centralising device 2, and the top of centralising device 2 is equipped with instrument
Table detection device 8, the right end of centralising device 2 are equipped with weighing device 3, are provided with rear pipe carrying truck on front side of the driving track on right side
6, middle part is provided with support roller pipe carrying truck 5 between the driving track of two sides, and the middle and upper part between two groups of driving tracks is equipped with spray gun
Device 7, spray gun device 7 are located at the surface of support roller pipe carrying truck 5.
Wherein, weighing device 3 is detected using reflective photoelectric switch, and spray gun device 7 includes hoist engine and five groups of spray heads, volume
It raises machine to connect simultaneously by lifting rope with five groups of spray heads, 8 test object of instrument detection device includes the switch of Position of Hydraulic Cylinder detection
Measure signal, the code device signal of small truck position and Burners Positions, cast detection laser range sensor 4-20mA signal and
The 4-20mA signal of weighing instrument, the detection mode of instrument detection device 8 are laser range finder detection.
Working principle：Before cast tube is through driving track to be rolled to separation device 1, cast tube is dialed to centralising device 2 by separation device 1
Go up and carry out centering operation, by instrument detection device 8 detect cast, and be allocated to weighing device 3 weighing, acquire data after automatically by
Preceding pipe carrying truck 4 is sent to support roller pipe carrying truck 5, is sprayed through spray gun adjustment device 7 according to the cast adjust automatically that instrument detection device 8 detects
Rifle position is set, and spray zinc process is completed, and cast tube is transported to spray zinc rear-guard dynamic rail road by support roller pipe carrying truck 5 by rear pipe carrying truck 6, spray zinc is thick
Degree calculates automatically according to target call and controls spray gun wire feed rate, can be achieved after the completion of above procedure debugging unattended.
The regulation of this programme needs that intelligent control PLC system is combined to work, and PLC system is by having pipe to separation device 1
Detection signal, centering caliber identification signal, weighing position have pipe detection signal to be analyzed and determined, such as：If centering position is divided without pipe
Pipe device 1 is from 2 inlet pipe of trend centralising device, if weighing device 3, without pipe, centralising device 2 has pipe, then centralising device 2 by cast tube with
Bellmouth side is aligned and acquires from 3 inlet pipe of trend weighing device after tube type data, when cast tube is surveyed by centering, cast confirmation, weighing
It is transported on support roller pipe carrying truck 5 after amount by preceding pipe carrying truck 4, spray gun lifting elevator motor is sensed according to laser ranging at centralising device 2
Device acquisition distance signal judge the cast of the pipe and automatically control dropping distance, while according to the cast tube model distribute it is corresponding
The wire feed rate of support roller pipe carrying truck 5 forward speed and support roller rotation speed and spray gun completes the spray zinc process of cast tube, works as support roller
In vehicle fallback procedures, spray gun elevating mechanism rises to standby position, and rear pipe carrying truck 6, which advances, to be taken over, and preceding pipe carrying truck 4 is according to rear pipe carrying truck
6 complete 5 upper tube of support roller pipe carrying truck with 5 advanced in unison of support roller pipe carrying truck, shorten the fortune pipe time, due to using the segmentation spray of more spray guns
Zinc, reduces 5 forward stroke of support roller pipe carrying truck, in actual use, support roller pipe carrying truck 5 need to advance 1.6 meters or so it is just achievable
The spray zinc operation of whole cast tube.
The principle of cast detection is that laser range sensor is mounted on above centralising device fixation at 2.8 meters away from ground, choosing
With the laser range sensor of 0-10m range, exports 4-20mA and correspond to 0-3000mm, postpone 2 after cast tube is with the centering of bellmouth side
Second carries out cast confirmation, and cast tube remains static at this time, and actually detected 1mm or so error is fully met to cast tube cast
Judgement needs.
The control of preceding pipe carrying truck 4, rear pipe carrying truck 6 is PLC according to its drawstring encoder position signal to control pipe carrying truck
The speed of frequency converter in different location areas, for example, before pipe carrying truck 4 advance to from weighing device 3 to pipe position, velocity variations from
0HZ (before starting) -40HZ (after starting) -10HZ (distance is to pipe position 200mm) -0HZ (to pipe position), preceding pipe carrying truck 4 is from support roller
Pipe carrying truck 5 is retreated to weighing device 3, and velocity variations are from 0HZ (before starting) -40HZ (after starting) -5HZ (apart from weighing position
300) -0HZ (to weighing position).
The principle of zinc coating thickness control is derived by the conservation of mass：
K π D2V2=7.14 π (D1/2)2V1*2*0.3
It is reduced to kD2V2=4.28 (D1/2)2V1
Wherein K is spray zinc target set point (example：200g/m2)
D2 is cast tube outer diameter, and D1 is zinc silk diameter, and V2 is support roller vehicle speed, and V1 is spray zinc wire feed rate.The above variable K,
D1, D2 are known quantity, and V2 is set according to technique rhythm of production.To show that V1 sets spray gun as initial value.
Actual effect is determined using rice membrane weighting manner after spray gun sprays zinc according to setting value, is inserted in touch screen, is swashed
Work is calculated, and PLC is modified wire feed rate according to following equation with actual value relationship according to target value, to meet zinc layers mesh
Mark requires.
V1 '=0.3*V1 (1-e(K1/K2-1))+V1
The zinc silk wheel diameter taken in the utility model experiment is 40mm, wire feeding motor reduction ratio 7.8, zinc silk 4mm, spray zinc
Target is 200g/m2Technique rhythm was calculated according to 1 minute 1 root canal, and support roller vehicle speed of service at 50HZ is 0.24m/s, was removed
Fixed time-consuming (spray gun adjustment mechanism, fortune pipe process etc.) about 10 seconds, support roller pipe carrying truck 5 returns initial bit 5 seconds, practical support roller pipe carrying truck
5 forward speeds are about that 1.6m/45s ≈ 0.036m/s, V2 ≈ 7.4HZ. with DN500 cast tube carries out spray zinc, initial wire feed rate V1
=0.22m/s, frequency conversion set about 820 revs/min automatically.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
