Embodiment 1

[0036] see Figure 1-6 , the present invention provides a technical solution: a protection device for a plastic-coated steel pipe with a flange, including a mounting plate 1, a stud 3, an inner support frame 5 and an outer buckle frame 7, and the center of the mounting plate 1 is fixedly connected with a screw Set 2, the inner side of the screw sleeve 2 is screwed and connected with a stud 3, the left end of the stud 3 is fixedly connected with a hoisting ring 301, the right end of the stud 3 is rotatably connected with a turntable 4, and the inside of the mounting plate 1 is located outside the screw sleeve 2 Four groups of inner brackets 5 distributed in a circular array are connected by rotation, and the inside of the four groups of inner brackets 5 is provided with a chute 501. The outer circumference is rotatably connected with four sets of outer buckle frames 7 distributed in a circular array, the outside of the stud 3 is located on the right side of the hoisting ring 30...

Embodiment 2

[0038] Specifically, such as figure 1 , figure 2 and Figure 4As shown, the right end surface of the mounting plate 1 is fixedly connected with multiple sets of positioning columns 101 distributed in a circular array, and the outside of the four sets of outer buckle frames 7 are all provided with inclined blocks 8, and the outside of the four sets of outer buckle frames 7 are located on the outside of the outer buckle A squeeze spring 9 is sleeved between the right end of the frame 7 and the right end face of the inclined block 8, and the right ends of the four sets of inner brackets 5 are fixedly connected with an arc bar 6, and the outer end face of the arc bar 6 is embedded with a rubber gasket 601 , and the outside of the rubber gasket 601 is equidistantly fixedly connected with multiple groups of convex balls 602, and the setting of the positioning column 101 facilitates the butt joint processing between the mounting plate 1 and the flange plate, and reduces the gap bet...

Embodiment 3

[0040] Specifically, such as figure 1 , image 3 , Figure 5 and Figure 6 As shown, two groups of assembly blocks 102 are symmetrically fixedly connected to the outer periphery of the installation disk 1, and two groups of assembly grooves 103 are symmetrically opened on the outer periphery of the installation disk 1 between the two groups of assembly blocks 102, and the left end surface of the installation disk 1 is close to the two groups of assembly blocks. One side of the groove 103 is slidably embedded with a sliding column 12 that runs through the assembly groove 103, and the outside of the sliding column 12 is sleeved with a tension spring 13, and the two ends of the tension spring 13 are connected to the left end of the sliding column 12 and the mounting plate 1 respectively. The left end face of the two sets of assembly blocks 102 are provided with sliding holes 1021 on the side close to the sliding column 12, and the sliding holes 1021 and the sliding column 12 ar...

Abstract

The invention discloses a protective device with a flange plastic-coated steel tube and a protective packaging method thereof. The protective device comprises mounting discs, a stud, an inner supporting frame and an outer locking frame, wherein the circle centers of the mounting discs are fixedly connected to screw sleeves; the inner sides of the screw sleeves are rotatably connected to the stud;the left end of the stud is fixedly connected to a hoisting ring; and the right end of the stud is rotatably connected to a rotary disc. According to the protective device with the flange plastic-coated steel tube disclosed by the invention, a bracket type transportation structure is adopted, and a plastic-coated steel tube bracket can be mounted between two groups of mounting discs, so that innersurface wall contact wear phenomena of the plastic-coated steel tube during the plastic-coated steel tube hoisting and transporting are reduced, and therefore, protective performance during plastic-coated steel tube transportation is improved; and a stacking splicing structure is arranged inside the plastic-coated steel tube, so that the plastic-coated steel tube is in non-contact type stacking and transporting, and outer surface wall collision and scratch phenomena of the plastic-coated steel tube during plastic-coated steel tube stacking and transporting are reduced, and therefore, protective performance for plastic-coated steel tube transportation is further improved, and the service life of the plastic-coated steel tube is prolonged.

Description

technical field [0001] The invention relates to the technical field of plastic-coated steel pipe transportation protection components, in particular to a protective device for a plastic-coated steel pipe with a flange and a protective packaging method thereof. Background technique [0002] Plastic-coated steel pipes, also known as plastic-coated pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, use steel pipes as the substrate, and weld a layer of plastic anti-corrosion layer or Steel-plastic composite steel pipe with plastic anti-corrosion layer welded on the inner and outer surfaces. Plastic-coated steel pipe has excellent corrosion resistance and relatively small frictional resistance. The plastic-coated steel pipe with flange is based on the original plastic-coated steel pipe, and flanges are fixed at both ends of the plastic-coated steel pipe, so as to facilitate the butt joint and installation of the plastic-coated steel pipe. [0003] N...
