Problems solved by technology

[0003] The existing 3PE anti-corrosion production process, such as the Chinese invention patent with application number 201310483454.4, discloses a steel pipe anti-corrosion coating production line and coating process, including a coating transmission line, which is sequentially equipped with steel pipe shot blasting Rust removal device, first intermediate frequency heating device, painting device, second intermediate frequency heating device, epoxy powder coating device, adhesive extruder, polyethylene extruder and water cooling system; applied to the coating on this production line The process mainly includes shot blasting, intermediate frequency heating, spraying, cooling and other steps. During the coating process, the steel pipe has both forward movement and circumferential rotation, and the diameter of the steel pipe is divided into different sizes. The existing coating The transmission line is only suitable for steel pipes of a certain size, not for small diameter steel pipes

Embodiment 1

[0023] Embodiment 1: as figure 1 , figure 2 and image 3 As shown, a small-diameter steel pipe 3PE external anti-corrosion transmission line includes a plurality of transmission components arranged in a straight line. The transmission component includes a base 1 and a pair of transmission wheels arranged on the base 1. The axes are parallel to each other, the rotation axis of the transmission wheel and the conveying direction of the steel pipe form an included angle α, the size of the included angle α is adjusted according to the conveying speed, generally the size of the included angle α is between 10°-25°.

[0024] At least one transmission wheel is movably mounted on the base 1 to adjust the distance between two adjacent transmission wheels. Wherein the driving wheel comprises a driving wheel 4 and a driven wheel 5, the driving wheel 4 and the driven wheel 5 are distributed on the base 1 left and right, the base 1 is provided with a fixed support 2 and a movable support ...

Embodiment 2

[0028] Embodiment 2: as Figure 4As shown, the difference from Embodiment 1 is that a linkage mechanism 9 is provided between the swing frame 6 and the movable bracket 3, and when the movable bracket 3 moves closer to or away from the fixed bracket 2, the swing frame 6 is driven by the linkage mechanism 9. Swing in the opposite direction. That is, when the movable support 3 moves toward the direction close to the fixed support 2 , the swing frame 6 swings toward the direction away from the fixed support 2 . Linkage mechanism 9 comprises worm gear 91, the worm screw 92 that drives worm gear 91 to rotate, the cylindrical gear 93 that drives worm screw 92 to rotate, and described worm gear 91 is arranged on the rotation center of described swing frame 6, and is fixedly connected with described swing frame 6, The worm 92 is rotatably mounted on the movable bracket 3, the rotation axis of the worm 92 points to the moving direction of the movable bracket 3, and the cylindrical gear...

Abstract

The invention relates to a small-aperture steel tube 3PE outer anti-corrosion transmission line. The small-aperture steel tube 3PE outer anti-corrosion transmission line comprises a transmission component, wherein the transmission component comprises a base and transmission wheels, wherein at least one transmission wheel is movably mounted on the base so as to adjust the distance between every twoadjacent transmission wheels; the axis of at least one transmission wheel is provided with a swing frame, the end of the swing frame is provided with an auxiliary wheel, the auxiliary wheel is provided with at least two swing positions, one swing position is positioned at the position close to the other transmission wheel and a small-aperture steel tube supporting structure for supporting small-aperture steel tubes is formed by the transmission wheel, and the other swing position is positioned at the position away from the other transmission wheel and a large-aperture steel tube supporting structure for supporting large-aperture steel tubes is formed by two transmission wheels. The conveying state switching of the large-aperture steel tubes and small-aperture steel tubes can be realized,the switching is simple and convenient, the utilization rate of the transmission line is improved, moreover, the central positions of the steel tubes before and after switching are always positioned in the center of the transmission line, and the workload of adjusting the transmission line is reduced.

Description

technical field [0001] The invention relates to the technical field of steel pipe transmission equipment, in particular to a small-diameter steel pipe 3PE external anti-corrosion transmission line. Background technique [0002] When ordinary steel pipes are used in harsh environments, severe corrosion will occur, which will reduce the service life of the steel pipes. The 3PE anti-corrosion steel pipe has relatively strong waterproof and corrosion resistance, and can be directly buried in the ground or water. It is also simple and fast in construction, and the overall cost is relatively low. It also has good corrosion resistance and impact resistance under low temperature conditions. sex. Therefore, 3PE anti-corrosion steel pipes are widely used, such as coal mine underground water supply and drainage, underground spraying, positive and negative pressure ventilation, gas extraction, fire sprinkler and other pipe networks; thermal power plant process water waste residue, retu...
