Description

Technical Field

[0001] The utility model relates to the technical field of automatic spray marking, in particular to an automatic spray marking device for a small-diameter graduation line. Background Art

[0002] In the processing and manufacturing process of the foundation section of modern wind power equipment, such as towers, monopiles, cages, conductor racks and booster stations, these products have many pipe parts. For large-diameter pipe parts (such as diameter ≥1200mm), they are generally made of steel plates after cutting and then processed by three-roll or four-roll mechanical rolling. For medium-sized pipe diameter steel pipes with a diameter between 610mm and 1200mm, they are generally made of plates after cutting and cold-pressed into straight-seam steel pipes, and then made into various styles of pipe parts. For pipe parts with a diameter less than 610mm, seamless steel pipes are generally purchased directly, and then cut into the required pipe parts using an intersecting line cutting machine. For small and medium-diameter parts, such as straight-seam pipes, seamless steel pipes, and small-diameter taper pipes, there are no four-point positioning lines after the parts are cut, which brings difficulties to the subsequent assembly of pipe parts. It is required that when the pipe parts are assembled into components, each longitudinal seam needs to be assembled to the angle position specified in the design drawings.

[0003] Deficiencies of existing technology:

[0004] At present, small and medium diameter parts, such as straight seam pipes, seamless steel pipes, and small diameter taper pipes, have no four-point positioning lines after cutting. This brings difficulties to the subsequent assembly of pipe parts. It is required that when the pipe parts are assembled into parts, each longitudinal seam needs to be assembled to the angle position specified in the design drawings. This process is performed by on-site workers based on experience, and the longitudinal seam position of each pipe part is roughly calculated for assembly. This is not only labor-intensive and inefficient in pipe part assembly, but also often leads to assembly errors due to miscalculations, which lead to rework. Utility Model Content

[0036] Example

[0037] See also Figure 1-3As shown, the utility model provides a technical solution for an automatic spray marking device for a small-diameter dividing line: comprising a fixed track platform 110, wherein the length direction, width direction and height direction of the fixed track platform 110 are respectively a first direction x, a second direction y and a third direction z, and the first direction x, the second direction y and the third direction z are perpendicular to each other; a fixing assembly, a sliding assembly and a spray marking assembly are arranged on the fixed track platform 110, and the fixing assembly is installed on the fixed track platform 110, and the fixing assembly comprises two first tracks 121 and fixed expansion bolts 122, wherein the two first tracks 121 are arranged in parallel and spaced apart on the fixed track platform 110 in the first direction x, and the fixed expansion bolts 122 are arranged in parallel and spaced apart on the fixed track platform 110 in the first direction x, and the fixed expansion bolts 122 are arranged in parallel and spaced apart on the fixed track platform 110 in the first direction x, and the fixed expansion bolts 122 are arranged in parallel and spaced apart on the fixed track platform 110 in the first direction x, and the fixed expansion bolts 122 are arranged in the second direction y, and the fixed expansion bolts 122 are arranged in the third direction z ... Bolts 122 are installed at the bottom ends of both sides of the fixed track platform 110, and a number of leveling washers 123 and track fixing clamps 124 are arranged at equal intervals on the two first tracks 121. The leveling washers 123 and the track fixing clamps 124 enable the sliding assembly to move smoothly on the two first tracks 121; multiple fixed track platforms 110 are assembled into a pipe marking production line, which consists of three fixed track platforms 110. During this process, a laser theodolite is needed to control the flatness and straightness of both ends of the fixed track platform 110, so that the fixed track platform 110 can meet the design standards, improve efficiency and enable multiple pipe parts to be marked with four-point lines.

[0038] Furthermore, the sliding assembly includes a fixed sliding groove 131, a double-headed screw 132, two sliding blocks 133, an adjusting handle 134 and a supporting structure 135. The fixed sliding groove 131 is connected to the fixed track platform 110 by being provided with a sliding device. The sliding device can be set as a track roller 136. The fixed sliding groove 131 is connected to the track roller 136. The track roller 136 drives the fixed sliding groove 131 to translate in a first direction x on the two first tracks 121. The double-headed screw 132 is installed on the fixed sliding groove 131 in a second direction y. The threads on the double-headed screw 132 face opposite directions. The adjusting handle 134 is set at both ends of the double-headed screw 132. The supporting structure 135 is movably set on the double-headed screw 132 by connecting the two sliding blocks 133. When the adjusting handle 134 is rotated, the supporting structure 135 can move to both sides of the double-headed screw 132 or to the center of the double-headed screw 132 at the same time, thereby achieving the purpose of cooperating and supporting pipe parts with different diameters.

[0039] Furthermore, the supporting structure 135 includes two movable frames 1351, a second shaft wheel 1353 and two tube support rollers 1354. The two movable frames 1351 are movably connected to the stud screw 132 by two first shaft wheels 1352. The two movable frames 1351 are connected by the second shaft wheel 1353. The two tube support rollers 1354 are connected to the tops of the two movable frames 1351 by two sets of shafts and sleeves 1355. The two tube support rollers 1354 cooperate with the rotation of the tube parts. By rotating the adjustment handle 134, the two sliding blocks 133 drive the two movable frames 1351 to move toward the two sides or the center of the stud screw 132 at the same time. When the two movable frames 1351 move toward the center of the stud screw 132 at the same time, the tops of the two movable frames 1351 approach each other to cooperate with the tube parts with slightly smaller diameters. When the two movable frames 1351 move to the two sides of the stud screw 132 at the same time, the tops of the two movable frames 1351 move away from each other to cooperate with the tube parts with slightly larger diameters.

[0040] Furthermore, the marking assembly includes a second track 141 and an intelligent longitudinal seam identification and marking system 142. The second track 141 is parallelly arranged in the first direction x in contact with the fixed track platform 110. The intelligent longitudinal seam identification and marking system 142 is slidably arranged on the second track 141, and the intelligent longitudinal seam identification and marking system 142 moves in the first direction x on the second track 141. The pipe parts are hung on the top of the two movable frames 1351. The intelligent longitudinal seam identification and marking system 142 first finds the longitudinal seam position of the pipe parts, rotates the angle α according to the design drawing, and then moves to the 0° line. The nozzle on the intelligent longitudinal seam identification and marking system 142 is started to automatically spray a 300mm long white straight line to mark 0. °, then the nozzle on the intelligent longitudinal seam identification and marking system 142 rotates 90° along the outer diameter of the pipe and sprays out a 90° white straight line to mark 90°, and then marks 180° and 270° in a similar manner. After one end of the pipe part is marked, the intelligent longitudinal seam identification and marking system 142 moves to the other end of the pipe part to spray the same four-point line. The intelligent longitudinal seam identification and marking system 142 does not require manual wire pulling and has low labor intensity. Whether the end of the pipe part is straight or penetrated by each other, it can automatically and efficiently identify and mark the pipe end four-point line, providing a precise assembly basis for subsequent component assembly, and the assembly accuracy of the pipe parts reaches 100%, the efficiency is greatly improved, and good economic benefits can be created.

[0041] The working principle of the utility model is as follows:

[0042] When using the small-diameter graduation line automatic marking device of this embodiment, the pipe parts are hung on the top of the two movable frames 1351, and the intelligent longitudinal seam recognition and marking system 142 first finds the longitudinal seam position of the pipe parts, rotates by an angle α according to the design drawing and moves to the 0° line, and starts the nozzle on the intelligent longitudinal seam recognition and marking system 142 to automatically spray a 300mm long white straight line to mark 0°, and then the nozzle on the intelligent longitudinal seam recognition and marking system 142 rotates 90° along the outer diameter of the pipe and sprays a 90° white straight line to mark 90°. 180° and 270° are marked in a similar manner. After one end of the pipe part is marked, the intelligent longitudinal seam recognition and marking system 142 moves to the other end of the pipe part to mark the same four-point line. The intelligent longitudinal seam recognition and marking system 142 does not require manual wire pulling and has low labor intensity. Whether the ends of the pipe parts are straight or interpenetrating, the four-point lines of the pipe ends can be automatically and efficiently identified, providing a precise assembly basis for subsequent component assembly. In addition, the assembly accuracy of the pipe parts reaches 100%, and the efficiency is greatly improved, which can create good economic benefits.
