[specific embodiment]
Consult Fig. 1, vertically stepping chain 1 is formed a whole by 5 independent chain delivery machanisms, considers that mainly overall distance is oversize, and the middle material toggling mechanism 2 that hydraulic pressure will be installed, and therefore is divided into 5 parts.The material toggling mechanism 2 of hydraulic pressure has three, can be fit to from the steel pipe of 6.5m-13.5m specification.Heating circulation system 3 is parts of baking oven 4.Laterally stepping chain 5 is installed in the baking oven and extends to baking oven 4 outsides, is used for conveying steel pipe, and 4 altogether, the 6th, the drive part of horizontal stepping chain, power is exported by reductor, drives horizontal stepping chain 5 by the axle that links together and advances.
Consult Fig. 2,3,4, vertically the main effect of stepping chain is static relatively being fed forward of steel pipe that will be coated with oil, and reduces and the contacting of steel pipe as far as possible, with the destruction of minimizing to the steel tube surface oil film.Chain 13 is installed on drive sprocket 9 and by on the movable sprocket 15, drive sprocket 9 and be fixed on drive end base 7, preceding end support 10 and the back end support 14 by front end bearing block 8 and rear end bearing seat 16 respectively by movable sprocket 15, chain track 19 is fixed on the support 12, be the intermediate supports of chain 13, can guarantee moving forward of chain 13 high-speed smooth; At interval vee-block is installed on the chain 13, can holds the steel pipe reach and can effectively reduce contacting of steel pipe and supporter, as Fig. 5,6,7; Chain 13 can be lax gradually in the long-term operation process, so regulate leading screw 17 in the driven end setting by tensioning; Vertically the power of stepping chain is provided by drive motors and reductor 20, and can realize frequency control, has reached the purpose that is complementary with other rollgang speed of front and back.Drive static relatively the moving forward of steel pipe when vertically the stepping chain is worked, after steel pipe is run into limit switch, halt, begin to continue to drive next root steel pipe after material toggling mechanism 2 delivers to steel pipe on the horizontal stepping chain 5 and advance.
Consult Fig. 8, the material toggling mechanism 2 of hydraulic pressure has three, is installed on the centre of vertical stepping chain 1 at interval, be used for the oiling steel pipe is transported to horizontal stepping chain 5, and then laterally the drive of stepping chain 5 is dried through baking oven 4 down.The dolly 24 of material toggling mechanism is equipped with four wheels 28 below by axletree 31, and wheel is equipped with guide rail 32 28 times, can make things convenient for dolly to move forward and backward; Moving of dolly 24 provided by horizontal oil cylinder 21, and laterally oil cylinder 21 is pendulum model oil cylinders, and middle hold-down support is 22, and horizontal oil cylinder 21 is fixed on the ground, and front end links to each other with dolly 24 by ear seat 23; Dolly 24 is provided with V-arrangement bearing 25, be used to hold up steel pipe, it can lifting, V-arrangement bearing 25 is driven to rise by vertical oil cylinder 29 and holds steel pipe when steel pipe advances to baking oven 4 fronts, be raised to laterally oil cylinder 21 withdrawals of high some back, fall after drive dolly 24 and steel pipe move on the horizontal stepping chain, laterally oil cylinder 21 stretches out dolly 24 is pushed back to the arrival that next steel pipe is waited in the home position; Steady in order to guarantee 25 liftings of V-arrangement bearing, the spy is provided with guide pillar 26 and guide column sleeve 27.The dolly of material toggling mechanism has four stations in two positions, horizontal oil cylinder 21 stretches out under the duty, dolly 24 is parked in the middle of vertical stepping chain, V-arrangement bearing 25 is in low level, the wait steel pipe passes through, vertical stepping chain quits work when steel pipe knocks the limit switch of vertical stepping chain 1 back down, the dolly 24 of material toggling mechanism 2 rises, steel pipe integral is held up, laterally oil cylinder 21 withdrawal drive dollies 24 and steel pipe move on the V-arrangement bearing of horizontal stepping chain 5, fall then, with steel pipe be placed on the horizontal stepping chain back laterally oil cylinder 21 stretch out the arrival that dolly 24 is pushed into the next steel pipe of wait vertical stepping chain under.
Consult Fig. 9,10, be the heating circulation system of baking oven 4, form by blower fan 33, damper 34, joint 35, connecting hose 36, first ajutage 38, second ajutage 41, first backwind tube 37, second backwind tube 39, the 3rd backwind tube 42, some electric heaters 40 etc.Five electric heaters 40 distribute and are installed in a side of baking oven 4, after blower fan 33 starts with wind to five electric heaters 40, the heat that electric heater 40 is produced circulates in baking oven 4, and with the heating impelling of the steel pipe after the oiling quick surface drying of antirust oil, ventilation volume is by damper 34 controls.
Consult Figure 11, the structural representation of baking oven 4, the crossbeam 45 of arch is disposed across on the column 43 of side, the equal covering and heat insulating plate in the side of the top and column 43 of crossbeam 45, to prevent that heat scatters and disappears, the gateway of the turnover steel pipe of baking oven 4 respectively has one to block door curtain, falls on the steel pipe 46 always, prevents that hot blast from dispelling the loss of heat amount outward; Top at baking oven is provided with temperature sensor, remain under the temperature constant state with the temperature in the control baking oven, but blower fan is to be in the unlatching ventilation state always, by drying by the fire the mobile antirust oil drying that can quicken steel tube surface of air in 4.
Consult Figure 12, laterally stepping chain 5 and the vertically structural similarity of stepping chain 1, by horizontal drive sprocket 47, horizontal driven sprocket 56, lateral tension governor motion 49, horizontal front-end bearing pedestal 48, horizontal rear bearing block 55, horizontal support 54, horizontal chain 50, horizontal level gauge 52, two side shields, 53 compositions such as grade, different is the pattern difference of horizontal chain 50, its transverse width is less than vertical stepping chain chain 13, swash plate between two pitches lumps together and just forms the V-arrangement bearing, can the supporting steel pipe translation, there is the side locating wheel both sides of chain, the chain straight line is transmitted, do not make its sideslip.But the laterally action continuous motion of stepping chain 5, but also intermittent movement, each is the chain station that advances intermittently, is intermittent movement under the normal operating conditions; During work after receiving a steel pipe on the horizontal stepping chain its station that advances, stop then and wait for the arrival of next steel pipe, steel pipe can be sent in the baking oven 4 and so forth and be sent.
The course of work: vertically stepping chain 1, material toggling mechanism 3 and horizontal stepping chain 5 open to automatic mode; Open hot air circulating system 3, make the temperature in the baking oven 4 reach setting value; The oiler of opening the right side carries out pipe coating, opening vertical stepping chain 1 drive steel pipe advances, after arriving the 3rd material toggling mechanism, steel pipe runs into limit switch, vertically stepping chain 1 halts, three material toggling mechanisms 2 begin action simultaneously, are retracted into initial position after delivering to steel pipe on the horizontal stepping chain 5 to wait for next steel pipe; Laterally stepping chain 5 is received and is moved forward a station behind the steel pipe and stop to wait for next steel pipe; So circulation, send the horizontal chain 50 of a steel pipe transverse stepping chain 5 station that advances, the quick surface drying of antirust oil when transporting steel pipe continuously and can make steel pipe pass through baking oven is when the oiling end-of-job can move through baking oven with steel pipe continuously with 5 dozens on horizontal stepping chain to normally open.Vertically stepping chain 1 and laterally stepping chain 5 linkages, crawl separately, can continuous motion also can intermittent movement, and speed variable ratio frequency changer speed governing is with suitable different speed of production.
The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
