Description

Technical Field

[0001] The invention relates to the technical field of elbow anti-corrosion, and in particular to a static multifunctional elbow anti-corrosion device. Background Art

[0002] Steel pipe anti-corrosion is the process of anti-corrosion treatment on the surface of steel pipe, including sandblasting, epoxy powder coating, medium frequency heating and 3PE winding, and the working principles of the above anti-corrosion methods are similar: an anti-corrosion machine head is set (the machine head can be a sandblasting, powder coating, heating, winding machine, etc.), the middle part of the anti-corrosion machine head can be used for the steel pipe to pass through, and then conveying rollers are set on both sides of the machine head. The conveying rollers convey the steel pipe through the anti-corrosion machine head, and the corresponding anti-corrosion operation can be performed on the steel pipe. For the anti-corrosion operation of the bent pipe, the conveying rollers on both sides of the head need to be arranged according to the curvature of the bent pipe. The conveying rollers convey the bent pipe along its own arc. When the bent pipe passes through the head, corresponding sandblasting, powder coating, heating, 3PE winding and other operations are performed. The applicant has previously applied for a patent for an automatic winding device for cold wrapping of bent pipes (publication number CN213112069U). The bent pipe can be conveyed to the winding head by the conveying rollers. The winding mechanism at the winding head wraps the bent pipe with 3PE, which can be wound evenly and stably and improve the winding efficiency. However, the conveying rollers on both sides of the winding head need to meet the support of the entire bent pipe to meet the support of the bent pipe before and after winding. That is, the total arc length of the conveying rollers on both sides of the winding head needs to be no less than twice the arc length of the bent pipe. Due to the large radius and length of the bent pipe, the arrangement of the conveying rollers takes up a lot of space, and when performing anti-corrosion wrapping operations on bent pipes with different curvatures and diameters, it is also necessary to adjust the position and placement angle of each conveying roller, which brings a lot of trouble and there is room for improvement.

The middle support portion 22 includes three middle support plates 221 arranged in parallel;

[0026] The working process of this embodiment is as follows: after the machine head corresponding to the anti-corrosion operation is installed on the machine head mounting seat 3, the fifth driving device 43 cooperates with the sixth driving device 45 to move the machine head mounting seat 3 along the arc of the bend from left to right, and the anti-corrosion machine head 31 first passes through the left support portion 21. At this time, there is a certain angle between the anti-corrosion machine head 31 and the three left support plates 211 (the bending angle of the bend generally does not exceed 90°, so the angle between the anti-corrosion machine head 31 and the three left support plates 211 is generally not greater than 45°). The two left support plates 211 on the left fall down in turn when the anti-corrosion machine head 31 passes by. When the anti-corrosion machine head 31 is about to move to the third left support plate 2113, since the anti-corrosion machine head 31 has a certain angle with the left support plate 211 at this time, the anti-corrosion machine head 31 The rear side of the machine head 31 is now located on the rear side of the first left support plate 2111, and the front side of the anti-corrosion machine head 31 is now located on the front side of the third left support plate 2113. The first left support plate 2111 and the third left support plate 2113 are smaller in size and do not interfere with the anti-corrosion machine head 31. At this time, the first left support plate 2111 pushes up to drag the steel pipe, and then the third left support plate 2113 falls, and the anti-corrosion machine head 31 leaves the left support portion 21. At this time, the second left support plate 2112 and the third left support plate 2113 are lifted up to support the steel pipe; then when the anti-corrosion machine head 31 passes through the three middle support plates 221, the angles between the anti-corrosion machine head 31 and the three middle support plates 221 are smaller. When the anti-corrosion machine head 31 passes through the three middle support plates 221 from left to right, the two middle support plates on the left The support plates 221 fall down in sequence when the anti-corrosion machine head 31 passes by. When the anti-corrosion machine head 31 is about to move to the third middle support plate 221, the anti-corrosion machine head 31 will leave the top of the first middle support plate 221, and the anti-corrosion machine head 31 will not interfere with the first middle support plate 221. At this time, the first middle support plate 221 pushes up to drag the steel pipe, and then the third middle support plate 221 falls down, and the anti-corrosion machine head 31 leaves the three middle support plates 221. At this time, the second and third middle support plates 221 are both lifted up to support the steel pipe; then the anti-corrosion machine head 31 passes by the right support part 23. At this time, there is a certain angle between the anti-corrosion machine head 31 and the three right support plates 231. The two right support plates 231 on the left fall down in sequence when the anti-corrosion machine head 31 passes by. When the anti-corrosion machine head 31 is about to move to the third right support plate 2313, since there is a certain angle between the anti-corrosion machine head 31 and the right support plate 231 at this time, the front side of the anti-corrosion machine head 31 is now located in front of the first right support plate 2311, and the rear side of the anti-corrosion machine head 31 is now located behind the third right support plate 2313. The first right support plate 2311 and the third right support plate 2313 are smaller in size and do not interfere with the anti-corrosion machine head 31. At this time, the first right support plate 2311 pushes up to drag the steel pipe, and then the third right support plate 2313 falls, and the anti-corrosion machine head 31 leaves the right support part 23. At this time, the second right support plate 2312 and the third right support plate 2313 are lifted up to support the steel pipe, and the anti-corrosion machine head 31 completes the corresponding anti-corrosion operation on the entire steel pipe.

[0027] like Figure 5 As shown, in another embodiment, a left turntable 216 and a ninth drive device 217 for driving the left turntable 216 to rotate are provided at the bottom of the first drive device 212 on the frame 1, and a right turntable 236 and a tenth drive device 237 for driving the right turntable 236 to rotate are provided at the bottom of the third drive device 232 on the frame 1. The ninth drive device 217 and the tenth drive device 237 can be motors, and gears are provided at the output ends of the motors. The left turntable 216 and the right turntable 236 are respectively engaged with the gears for transmission.

[0028] When the anti-corrosion machine head 31 moves to the middle support part 22, the left support plate 211 is lifted and the left support plate 211 is lifted. The middle support plates 221 fall down one by one from left to right following the movement of the anti-corrosion machine head 31, and before the anti-corrosion machine head 31 moves to the last middle support plate 221, the anti-corrosion machine head 31 needs to leave the top of the leftmost middle support plate 221, and the leftmost middle support plate 221 can be lifted up to drag the steel pipe, so that the anti-corrosion machine head 31 leaves the middle support part 22, and then all the middle support plates 221 can be lifted up to drag the steel pipe; when the anti-corrosion machine head 31 moves to the right support part 23, the right support plate 221 is lifted up to drag the steel pipe. The support plates 231 fall one by one from left to right following the movement of the anti-corrosion head 31, and before the anti-corrosion head 31 moves to the last right support plate 231, the anti-corrosion head 31 needs to leave the top of the leftmost right support plate 231, and the leftmost right support plate 231 can push up and drag the steel pipe, so that the anti-corrosion head 31 leaves the right support part 23, and then all the right support plates 231 can push up and drag the steel pipe, and the anti-corrosion head 31 completes the corresponding anti-corrosion operation on the entire steel pipe.
