Description
Technical field
The utility model relates at the uniform velocity control technology of a kind of large-scale steel pipe automatic application product line, particularly relates to a kind of constant speed control device of automatic adjusting steel pipe gait of march.
Background technology
Large-scale steel pipe corrosion-inhibiting coating automatic application product line comprises ball blast mechanism, steel pipe conveying mechanism and steel pipe to be sprayed paint carried out pre-warmed preheating drying room, paint spray booth, solidifies room and cooling room.In the production process, steel pipe is successively by each system of above-mentioned production line.
The connecting gear of steel pipe is made up of a plurality of turning rolls groups, each roller set is equipped with one or two variable-frequency motors, the rotating speed speed of variable-frequency motor is controlled by the output frequency size of frequency converter, the rotation of variable-frequency motor drives the roller rotation on the turning rolls group, the rotation of roller drives the rotation of steel pipe, because roller has certain angle, so when steel pipe rotates on roller, the frictional force that has direct of travel promotes it and travels forward, thereby the level of realization steel pipe on connecting gear advanced.Since the diameter of large-scale steel pipe usually at 0.5～2.4 meter, length at 12～90 meters, when its connecting gear at production line (turning rolls group) is gone up motion, inevitably have eccentric motion, when doing eccentric motion, can cause by steel pipe the load of motor inhomogeneous, the time and when becoming big and diminish, cause the gait of march of steel pipe sometimes fast and sometimes slow.Secondly, the preheating drying room of the automatic application product line that we are present is 9～14 meters, solidifying drying room is 10～13 meters, paint spray booth and cooling room are generally 1.5～2.5 meters, consider device security and coating quality problem, generally in the preheating room, solidify the room, in paint spray booth and the cooling room steel pipe conveying mechanism (turning rolls) can be set, when steel pipe advances to the preheating room, solidify the room, in the time of in the middle of paint spray booth and the cooling room, because driving the turning rolls group of steel pipe reduces, causing the load of the variable-frequency motor on the turning rolls group to add conference causes the rotating speed of steel pipe slack-off, and then cause the gait of march of steel pipe slack-off, on the contrary, when the turning rolls group that drives steel pipe increases, can cause the gait of march of steel pipe to accelerate.
In sum because the gait of march of steel pipe is inhomogeneous, when steel pipe when spraying, can cause the film thickness that is sprayed on steel tube surface inhomogeneous (the steel pipe gait of march is accelerated, the film thickness attenuation, the steel pipe gait of march slows down, the film thickness thickening), influence the quality of coating; From paint loss aspect, can cause the waste of resource, calculate by velocity variations 20%, the loss factor of paint can increase by 40%～50%, has increased construction cost.Be head it off, need develop a cover and regulate the constant speed control device of steel pipe gait of march automatically, this device can be regulated the gait of march of steel pipe automatically according to the situation of advancing in real time of steel pipe, guarantee that steel pipe can at the uniform velocity advance on the connecting gear (turning rolls group) of production line, guarantee the uniformity of the thickness of paint film, and energy savings.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of at above-mentioned prior art can effectively solve because the variation of the turning rolls group quantity that the eccentric motion of steel pipe and drive steel pipe are advanced, cause the steel pipe gait of march inhomogeneous, and then cause that coating thickness is inhomogeneous, the constant speed control device of the automatic adjusting steel pipe gait of march of the defective of energy waste.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this regulates the constant speed control device of steel pipe gait of march automatically, it is characterized in that: comprise

Comparator, the output of described velocity measuring device and described memory module all links to each other with comparator, and the steel pipe gait of march setting value of preserving in real-time gait of march value of steel pipe that described comparator measures described velocity measuring device and the memory module compares;
Controller, the output of described comparator links to each other with the input of this controller, the output of described controller be used to drive the Power Drive Unit that steel pipe advances and link to each other, described controller is controlled the size of described Power Drive Unit power output according to the output result of described comparator, thereby the gait of march of steel pipe is regulated.
Concrete, when the real-time gait of march value of measuring of steel pipe was lower than steel pipe gait of march setting value, the power output of controlling Power Drive Unit by controller strengthened, thereby the gait of march of steel pipe is accelerated, and reached the purpose that steel pipe is at the uniform velocity advanced; In like manner, when the real-time gait of march value of measuring of steel pipe is higher than steel pipe gait of march setting value, controls the Power Drive Unit output frequency by controller and reduce, thereby the gait of march of steel pipe is slowed down, reach the purpose that steel pipe is at the uniform velocity advanced.
As improvement, the constant speed control device of the automatic adjusting steel pipe gait of march that the utility model provides also comprises an input unit, and this input unit links to each other with described memory module, is used to import steel pipe gait of march setting value.
Preferably, described input unit is a touch display screen.
Described velocity measuring device can be taken turns for a rice of being close to steel pipe, also can take turns for the mensuration that speed measuring coder is housed.
Described controller is a PLC control module, and described Power Drive Unit is a variable-frequency motor, and this variable-frequency motor is connected with steel pipe by steel pipe conveying mechanism.
For the constant speed control device volume that makes the automatic adjusting steel pipe gait of march that the utility model provides is lighter, control conveniently, described memory module, described comparator and described controller three adopt same microprocessor with computing function to realize.
Compared with prior art, advantage of the present utility model is: can effectively solve because steel pipe causes the problem that film thickness is inhomogeneous, loss is excessive in that traveling process speed is inhomogeneous, can save resource greatly, reduce cost, raise labour efficiency.
