[0002] In the process of oil tank renovation, spraying is a crucial step, effectively preventing corrosion and extending the service life of the tank. Traditional oil tank spraying methods mostly rely on manual operation, which has many drawbacks.

[0040] A BIM-based spraying operation mechanism for oil tank renovation includes:

[0041] Support base 1, with support shaft 2 rotatably connected inside the support base 1. There are two support shafts 2. The inner end of the two support shafts 2 is fixedly connected to support base 3. The two support shafts 2 are symmetrically arranged on both sides of support base 3.

[0042] The second support base 3 includes a base plate 301 and an F-shaped plate 302. A rotating seat 5 is rotatably mounted inside the F-shaped plate 302.

[0043] One end of the support shaft 2 9 is fixedly connected to an electric telescopic rod 10, and the other end is fixedly connected to a driven gear 2 19. The telescopic end of the electric telescopic rod 10 is fixedly connected to a fixing plate 11, and a spray gun mechanism is fixedly installed inside the fixing plate 11. In this embodiment, there are two electric telescopic rods 10, and the telescopic directions of the two electric telescopic rods 10 are opposite and they are staggered to the left and right. By adjusting the angle of one electric telescopic rod 10 to be the same as the angle of the other electric telescopic rod 10, the two sets of spray gun mechanisms are aligned, allowing simultaneous spraying and improving spraying efficiency.

[0044] The spray gun mechanism includes a gun body 12 and a nozzle 13. The nozzle 13 is movably mounted on the output end of the gun body 12 and is detachably connected to the gun body 12. The nozzle 13 can be flexibly replaced so that different models of nozzle 13 can be used according to the spraying material and process requirements.

[0045] To achieve automated drive of the above structure, a drive mechanism one is fixedly installed inside the support base 1, a drive mechanism two is fixedly installed inside the support base 3, and a drive mechanism three is fixedly installed inside the fixed base 8.

The support base 1 can be fixedly installed through the mounting holes, and can be fixed to the movable track device to further improve the degree of freedom.

[0050] This invention also provides a BIM-based oil tank modification spraying control method, applied to the spraying operation mechanism described above, comprising the following steps:

[0051] S1: Create a 3D model of the oil tank in BIM software (such as Revit software), plan the spraying path according to the 3D model, and set the spraying parameters, such as spraying angle, spraying distance and paint usage.

[0052] S2: Convert the spraying path and spraying parameters into control commands and transmit them to the control module of the spraying operation mechanism;

[0053] S3: The control module, according to the control command, controls the actions of drive mechanism one, drive mechanism two, and drive mechanism three respectively, adjusting the pitch angle of support base two 3, the circumferential angle of support plate 7, and the pitch angle of electric telescopic rod 10, so that the nozzle 13 is aligned with the target spraying position. The control module dynamically adjusts the operating state of each drive mechanism based on the oil tank surface parameters in the three-dimensional model, including radius, curvature, and weld position data, to maintain the optimal spraying posture of the spray gun mechanism.

[0054] S4: The control module controls the extension and retraction of the electric telescopic rod 10 according to the spraying distance in the spraying parameters, and adjusts the distance between the nozzle 13 and the oil tank wall. The distance between the nozzle 13 and the oil tank wall is set to 30-50cm.

[0055] S5: Start the pump 16 to transport the paint in the material box 15 to the gun body 12 through the extraction pipe 17 and the guide pipe 18, and spray the oil tank wall with the nozzle 13. At the same time, the flow meter 25 monitors the paint flow rate in real time.

[0056] S6: According to the spraying path, the control module synchronously controls the coordinated movement of each drive mechanism and the electric telescopic rod 10, so that the nozzle 13 moves at a constant speed along the surface of the oil tank until the spraying operation is completed. The control module uses a PID algorithm to adjust the rotational speed of each drive mechanism and the extension / retraction amount of the electric telescopic rod 10 in real time to compensate for trajectory deviations during the spraying process.

[0057] All electrical equipment in this device is powered by an external power source and is controlled to operate and shut down via a matching control switch.

[0058] The working principle of this invention is as follows:

[0059] Preliminary preparation: Before construction, by creating or calling an existing precise model of the oil tank in BIM software, the optimal spraying path, spraying angle, spraying distance, and paint usage can be planned. These data are converted into control commands, which are directly issued to the three drive mechanisms and electric telescopic rod 10 of this device through the control module. By receiving the commands from the BIM system, the device executes precise movements in three-dimensional space, so that the spray gun always sprays the tank wall with the planned posture and distance.

[0060] Equipment fixing: The mechanism is fixed to the mobile construction platform or designated working position through the installation structure at the bottom of the support base 1 to ensure stable support.

[0061] Position adjustment: The control module starts drive mechanism one, the servo motor 20 drives the drive gear 22 to rotate through the reducer 21, and drives the support shaft 2 to rotate through the meshing with the driven gear 4, thereby adjusting the vertical angle of the support seat 3; drive mechanism two starts, the drive gear 22 meshes with the convex tooth 6 to drive the rotating seat 5 to rotate, thereby adjusting the circumferential direction of the support plate 7 and the spray gun mechanism; drive mechanism three starts, the drive gear 22 meshes with the driven gear 19 to drive the support shaft 9 to rotate, thereby adjusting the pitch angle of the electric telescopic rod 10 and the spray gun mechanism, so that the nozzle 13 is aligned with the initial spraying position.

[0062] Distance adaptation: The control module controls the extension and retraction of two electric telescopic rods 10 according to the oil tank size data in the BIM model, adjusting the distance between the spray nozzle and the oil tank wall (usually 30-50cm) to ensure the spraying effect.

[0063] Paint delivery and spraying: The pump 16 of the material extraction mechanism is started. The pump 16 extracts paint from the material tank 15 through the material extraction pipe 17 and delivers it to the gun body 12 through the guide pipe 18. The paint is sprayed out from the nozzle 13. The flow meter 25 monitors the paint flow rate. The control module controls each drive mechanism and moving platform synchronously according to the planned path to realize the automatic uniform spraying of the nozzle 13 along the surface of the oil tank. The remaining amount of paint in the material tank 15 can be observed through the level gauge 24.

[0064] Nozzle replacement: If it is necessary to adjust the coating thickness or spraying range, after turning off the pump 16, unscrew the current nozzle 13, replace it with a nozzle 13 with the appropriate orifice diameter, and restart the equipment to continue operation.

[0065] Work completed: After the spraying operation is finished, turn off all drive mechanisms and pump 16, open the cover of material tank 15 to replenish paint or clean material tank 15, and clean the spray nozzle 13 to prevent paint from solidifying and clogging.

[0066] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
