Description

Technical Field

[0001] The utility model relates to a paint spraying process, in particular to a pipeline paint spraying line structure. Background Art

[0002] The PT-1 internal bore sprayer is suitable for coating the interior of small and medium-sized pipes. It utilizes high-pressure paint delivered by an airless sprayer. This atomized paint is then sprayed evenly onto the pipe's inner surface through a specially designed nozzle, creating a hollow, diffused pattern. External pipe coating is typically done manually, with limited use of automated equipment. For medium- and large-sized pipes, the market is relatively small, resulting in limited economic benefits. Automated spraying equipment also carries heavy loads, making it prone to localized structural deformation and misaligned spraying. Furthermore, its adaptability to pipes of varying sizes varies, limiting its application range. Utility Model Content

[0013] like Figure 1-Figure 3 As shown, a pipeline painting line structure includes a base frame 1 extending in a linear direction. The base frame 1 serves as the bottom support for the entire process production line and is usually assembled and connected by several frame-type structures. It can be assembled according to the needs of use, and it is also convenient to adjust the spacing between modules. The base frame 1 is provided with rolling frames 2 arranged at even intervals. The base frame 1 is further provided with support frames 3 between the rolling frames 2 to assist in lifting the pipeline. The rolling frames 2 directly contact the pipeline and play a role in lifting or transferring. Therefore, their special shape is designed to facilitate smooth transfer. Since the spacing between the rolling frames 2 is still relatively large, in order to better share the pressure load, a support frame 3 is provided to improve the support effect.

[0014] The base frame 1 also features a linkage frame 4 on its side, which interlocks the rolling frames 2. It also includes electrically connected photoelectric switches, relays, and a spray gun mechanism. A photoelectric switch, short for photoelectric proximity switch, detects the presence of an object by activating a synchronous circuit when the object blocks or reflects a light beam. This detection is not limited to metal; any object that reflects (or blocks) light can be detected. The photoelectric switch converts input current into a light signal at its transmitter, which is then emitted. The receiver then detects the target object based on the intensity or presence of the received light. A relay is an electrical control device that, when the input quantity (stimulus quantity) changes to a specified level, causes a predetermined step change in the controlled quantity in the electrical output circuit. It interacts between a control system (also known as the input circuit) and a controlled system (also known as the output circuit). Commonly used in automated control circuits, it is essentially an "automatic switch" that uses a small current to control a large current. Therefore, it performs functions such as automatic regulation, safety protection, and circuit switching within the circuit. The photoelectric switch and relay control trigger the spray gun mechanism action, which is a relatively mature technical means and will not be elaborated on or limited in detail here. The design of the linkage frame 4 is to enhance synchronization, and the driving source can be a single rolling frame 2 or multiple rolling frames 2, depending on actual use needs.

[0015] The rolling frame 2 includes at least a bearing seat 5 and a rolling element 6. The bearing seat 5 is provided with a movable bearing 7 for the shaft connection of the rolling element 6. The diameter of the rolling element 6 gradually increases from the center to the two ends, and the rolling element 6 forms a truncated cone-shaped abutment portion 8 on both sides of the center. The abutment portion 8 has an abutment curved surface 9 inclined toward the center. The abutment curved surface 9 has an abutment contact point with the pipe at the top, and the rolling element 6 is coated with an anti-skid pad 10 on at least the abutment curved surface 9. The rolling element 6 has a special style that transfers the load force of the pipe to both sides. The two ends of the rolling element 6 bear more pressure to ensure structural stability. Since under ideal conditions, the abutment contact points in this embodiment are point contact, the friction resistance is increased by the anti-skid pad 10, and the pipe is smoothly transported or transferred. The use of the bearing seat 5 is convenient for disassembly and assembly, which is also conducive to the smooth use of the rolling element 6.

[0016] The support frame 3 includes a support base 11 arranged along the width of the base frame 1. The support base 11 is provided with a fixing portion 12 on both sides thereof, which is connected to the base frame 1. The top of the support base 11 is provided with an angled slope corresponding to the abutting curved surface 9. The support base 11 is provided with a short pad 13 and a long pad 14 on the angled slope, respectively. The short pad 13 and the long pad 14 are provided with fixing holes 15 for connecting to the support base 11. The support base 11 provides support and compensation, and also serves as an auxiliary support for the pipeline. It should be noted that the fixing portion 12 is similar to a reinforcing rib that can compensate for the tightness of the connection, while the difference between the short pad 13 and the long pad 14 lies in the limiting distance. That is, the long pad 14 can limit the position at a greater distance, effectively preventing the pipeline from deviating from the long pad 14 and protecting personnel safety. At the same time, in this embodiment, a linkage frame 4 is provided at one end of the short pad 13, which itself serves as a limiter for that side of the pipeline. The design of the fixing hole 15 is different from its load-bearing or vibration direction, and does not affect installation and use.

[0017] The linkage frame 4 includes an upper baffle 16, a vertical rod 17, a sprocket 18, a motor 19, and a chain 20. The upper baffle 16 is suspended above the sprocket 18 via the vertical rod 17. The rolling elements 6 are driven to rotate via the sprocket 18 and the chain 20. The output end of the motor 19 is linked to the rolling elements 6. The chain drive enhances transmission efficiency and provides greater torque. The upper baffle 16 also provides a certain degree of protection for this area.

[0018] The spray gun mechanism includes an adjustment frame 21, a spray head, and an adjustment seat 22. The adjustment frame 21 is provided with an arcuate slot 23, the spray head is fixed to the adjustment seat 22, and the adjustment seat 22 is provided with a locking member 24 fixed to the adjustment frame 21. The locking member 24 passes through the slot 23 and moves along the arcuate path of the slot 23. The locking member 24 includes a butterfly nut and a bolt. This allows the spray head to be adjusted according to usage needs, providing flexible operation and a stable structure. The spray gun mechanism also includes a positioning assembly that telescopically moves the adjustment seat 22. The positioning assembly can be an air cylinder, an oil cylinder, or other telescopic structure. This is a relatively mature technology and will not be elaborated on or limited in detail here.
