The specific embodiment
Embodiment
Fig. 1 is the structural representation of the simple and easy swan neck system embodiment of large diameter steel pipe of the present invention, as shown in Figure 1, comprise: be used for draw-gear 2, the swan neck system main body 3 of bending force being provided and being used to connect the holding clamp 4 of steel pipe 1 to be curved and draw-gear 2 to steel pipe 1 to be curved, one end of holding clamp 4 is the taper round steel, in the bend pipe process, it inserts steel pipe to be curved 1 inside, be fixedly connected with steel pipe 1 to be curved, Fig. 4 is the structural representation of holding clamp 4 among the simple and easy swan neck system embodiment of large diameter steel pipe of the present invention, and the angle of taper round steel is between 30 degree are spent to 50.The other end of holding clamp 4 is connected with draw-gear 2 by pull rope 5.Fig. 2 is the plan structure schematic diagram of the simple and easy swan neck system embodiment of large diameter steel pipe of the present invention, Fig. 3 is the side-looking structural representation of the simple and easy swan neck system embodiment of large diameter steel pipe of the present invention, as shown in Figures 2 and 3, swan neck system main body 3 comprises the side supports plate 31 that is fixedly connected with by bearing connecting rod 39, two fixedly running roller 32 and adjustable rollings 33, fixedly running roller 32 is connected with adjustable rolling and is connected with support plate 31 by turning cylinder 34, fixedly running roller 32 is connected with adjustable rolling and is connected by bearing with turning cylinder 34, like this so that fixedly running roller 32 and adjustable rolling 33 moving axis that under the effect of pull rope 5, rotates along with moving of steel pipe 1 to be curved rotate.Swan neck system main body 3 is provided with sliding rail 35, and adjustable rolling 33 is fixed on the sliding rail 35 by adjusting screw 36 and feed screw nut 37, can adjust adjustable rollings 33 and the fixing centre-to-centre spacing of running roller 32 by leading screw 36.In the bend pipe process, regulate adjustable rolling 33 and two fixing relative positions of running roller by adjusting adjusting screw 36 and feed screw nut 37, thereby formation is to the pressure of steel pipe 1 to be curved.Fixedly running roller 32 and adjustable rolling 33 are provided with groove 38, and groove 38 is the arc-shaped groove that adapts with steel pipe to be curved, so that the outer surface of steel pipe to be curved 1 is fitted with groove 38 in moving process all the time.Like this because in the moving process of steel pipe 1 to be curved, exist all the time the fixedly pressure of running roller 32 and 33 pairs of steel pipes 1 to be curved of adjustable rolling, thereby so that steel pipe to be curved 1 certain radian of formation after the bend pipe process finishes, satisfy the needs of site operation.And, because steel pipe 1 to be curved is in moving process, fixedly therefore running roller 32 and adjustable rolling 33 have been avoided forming cut in steel tube surface to be curved all the time along with steel pipe 1 to be curved rotates together, improve the aesthetics of tube bending to be curved rear surface, and avoided the appearance of dog leg phenomenon.
The core wheel of adjustable rolling 33 is positioned at two fixedly on the perpendicular bisector of running roller core wheel line in the present embodiment, adjustable rolling and fixedly the diameter of running roller select same case, two fixedly the core wheel spacing of running roller be not less than 2 times of stationary roll wheel diameter, above-mentioned measure, through experimental results show that, Effective Raise the operating efficiency of bend pipe operation, most of steel pipes can reach construction requirement through one to twice bend pipe operation.
In the present embodiment, pull rope 5 is selected steel wire rope, and draw-gear is selected hoist engine.
Therefore, the present invention adopts the simple and easy swan neck system of the large diameter steel pipe of said structure, has reached large diameter steel pipe is carried out crooked purpose, low price, easy construction can be satisfied fully large diameter steel pipe is carried out crooked needs, reduce construction cost, made things convenient for workman's construction.
It should be noted that at last: above embodiment is only in order to technical scheme of the present invention to be described but not limit it, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment or be equal to replacement technical scheme of the present invention, and these modifications or be equal to replacement and also can not make amended technical scheme break away from the spirit and scope of technical solution of the present invention.
