Three gemel points on the moving platform are arranged into an equilateral triangle, and three gemel points on the fixing platform are arranged into an equilateral triangle. The revolute pair is a common revolute pair and a ball assistant, and the hydraulic pressure is a double function cylinder rod fluid cylinder. The moving platform and the fixing platform can be a round, a regular polygon or other shaped geometry shape. The input of the mechanism is the length of the fluid cylinder on the three branches of the shunt-wound platform. The output is different positions fixed on the moving platform gun body end. Therefore, the utility model realizes the blowing position change of the carbon oxygen gun in the electric furnace. The utility model is characterized by a good structure, high real time capability and easy control.
Description
The utility model relates to a kind of mechanism kinematic device of electric furnace arrangement for producing steel water-cooled oxygen carbon spray gun, is particularly useful for the water-cooled oxygen carbon gun system that ultra-high power electric arc furnace disposed in electric furnace-continuous casting type short-flow production line.
At present, in electric-arc furnace steelmaking was produced, particularly the uhp electric arc furnace in the short-flow production line all was furnished with water-cooled oxygen carbon gun system, needed to adjust oxygen rifle position in smelting in good time.Yet the water cooled oxygen lance system that China introduces all adopts tandem mechanism to realize motion control, and power is provided by motor and cylinder, and kinematic behavior is poor.Cause that the rifle body is often blocked by furnace charge in actual smelting operation, can not in time spray gun be adjusted to desired position, motor overload tripping operation, rifle head often occur and phenomenon such as stop up, burn out, influenced the normal running of electric furnace.
In order to overcome the shortcoming that existing water-cooled oxygen carbon gun system kinematic behavior is poor, can not adjust oxygen rifle position in good time, the utility model proposes and adopt 3DOF parallel connection platform mechanism to realize the required motion of water-cooled oxygen carbon gun system, this mechanism's power is provided by hydro-pump, can not only improve the system dynamic characteristic, realize rifle body real-time action, and have that structure rigidity is good, supporting capacity strong, be convenient to advantage such as control.
The technical scheme that the utility model adopted is: system is made up of rifle body, 3-freedom parallel mechanism.Wherein parallel institution has three branches, hydro-cylinder is equipped with in each branch, and cylinder body is connected with fixed platform by revolute pair, and hydraulic stem is connected with moving platform by ball is secondary, three hinge points are arranged to equilateral triangle on the moving platform, and three hinge points are arranged to equilateral triangle on the fixed platform.Described kinematic pair is general type revolute pair, ball pair, and hydro-cylinder is a double-acting piston bar hydro-cylinder.Moving platform and fixed platform can be the geometrical shape of circle, regular polygon or Else Rule.The length of hydraulic stem in three branches that are input as parallel connection platform of this mechanism.Be output as the different positions that is fixed on moving platform upper cutting gun end.The variation of position thereby the realization carbon-oxygen gun is jetted in electric furnace.
The utlity model has following advantage:
1. the utility model utilizes 3-freedom parallel mechanism can realize the pose that carbonyl spray gun is different, has reality
Time property, precision height.
2. the utility model not only can be realized the motion of rifle body, and structure rigidity is good, can optimization system
Kinematic behavior, overcome the shortcoming that rifle body in the existing mechanism is difficult for real time kinematics.
3. the utility model control is simple, only needs the elongation of control hydraulic stem just can realize the motion of rifle body.
4. the utility model is simple in structure, low cost of manufacture.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a schematic diagram of mechanism of the present utility model.
Fig. 2 is a parallel connection platform list branch sketch.
Among the figure: 1. rifle body, 2. moving platform, 3. ball pair, 4. hydro-cylinder, 5. hydraulic stem,
6. revolute pair, 7. fixed platform.
Face is described in further detail the utility model in conjunction with the accompanying drawings.
As shown in Figure 1, utility model comprises: rifle body (1), moving platform (2), ball pair (3), hydro-cylinder (4), hydraulic stem (5), revolute pair (6), fixed platform (7).Wherein ball pair (3) goes up at moving platform (2) and constitutes equilateral triangle, revolute pair (6) goes up at fixed platform (7) and constitutes equilateral triangle, rifle body (1) is fixed on moving platform (2) center, revolute pair (6) one ends link to each other with fixed platform (7), link to each other with hydro-cylinder (4) center of the equilateral triangle that the rotational plane that makes hydro-cylinder (4) constituted by three revolute pairs (6) of the other end.For guaranteeing mechanism's stand under load simplification, preferably get fixed platform (7) perpendicular to horizontal plane, line of two revolute pairs (6) is a sea line on it, another revolute pair (6) is above this sea line.
Be illustrated in figure 2 as parallel connection platform list branch sketch, this branch is made up of ball pair (3), hydro-cylinder (4), hydraulic stem (5), revolute pair (6), revolute pair (6) one ends are fixed on the fixed platform (7), the other end links to each other with hydro-cylinder (4), and hydraulic stem (5) is connected with moving platform (2) by ball pair (3).
The utility model principle of work is:
The elongation of hydraulic stem (5) can be calculated according to hydraulic fluid flow rate in each single branch, and such three ramose length determine, thereby the pose of moving platform (2) determines that it is known that rifle body (1) is fixed on the center and the length of moving platform (2), and then the position of rifle head is determined.When the variable elongation of hydraulic stem (5), just can realize the winding-up change in location of rifle head.
