[0017] Reference Figures 1 to 4 As shown, this utility model provides an integrated equipment for multi-station tower surface pretreatment and spraying, including: a fixed frame 2, with main hydraulic cylinders 1 symmetrically connected to the upper surface of the fixed frame 2, the telescopic rods of the main hydraulic cylinders 1 being fixedly connected to a lifting plate 3, and the lower end of the lifting plate 3 being movably connected to a main screw 4 via a bearing, one end of the main screw 4 being connected to a main motor 17 via a coupling, and main moving plates 5 being symmetrically screwed to both ends of the main screw 4, the lower end of the main moving plate 5 being fixedly connected to a base plate 7 via a reinforcing plate 6, and an auxiliary hydraulic cylinder 9 being fixedly connected to the surface of the base plate 7, the telescopic rods at both ends of the auxiliary hydraulic cylinder 9 being symmetrically connected to clamping plates 8, and the bottom of the inner cavity of the fixed frame 2 being fixed. A connecting guide plate 11 is connected to a secondary lead screw 10 via a bearing on its upper surface. The secondary lead screw 10 is connected to a secondary motor 16 via a coupling. A secondary moving plate 13 is slidably connected to the upper surface of the guide plate 11. A main slider 12 is fixedly connected to the upper surface of the secondary moving plate 13. The main slider 12 is screwed to the secondary lead screw 10. An adjusting lead screw 14 is movably connected to the inner cavity of the secondary moving plate 13 via a bearing. The adjusting lead screw 14 is connected to a mounting plate 20 via a screwed secondary slider 15. The adjusting lead screw 14 is connected to an adjusting motor 21 via a coupling. A spraying assembly 18 is fixedly connected to the upper surface of the mounting plate 20. An air pump 19 is fixedly connected to the side of the mounting plate 20.

[0018] In this embodiment, the tower is moved into the inner cavity of the fixed frame 2 by a mobile device. When the main hydraulic cylinder 1 is activated, its extension rod pushes the main moving plate 5 and the base plate 7 downwards synchronously, so that the clamping plate 8 on the surface of the base plate 7 is aligned with the inner cavity of the tower. When the main motor 17 is activated, it drives the main lead screw 4 via a coupling. The main lead screw 4, through the screwed main moving plate 5, drives the reinforcing plate 6, the base plate 7, the auxiliary hydraulic cylinder 9, and the clamping plate 8 to move synchronously, allowing the clamping plate 8 to embed into the tower. The positioning block on the surface of the clamping plate 8 smoothly abuts against the end face of the tower. The auxiliary hydraulic cylinder is then activated. Switching cylinder 9 activates the two sets of lifting rods at both ends of the auxiliary hydraulic cylinder 9, which simultaneously push the two sets of clamping plates 8 to move in opposite directions. This allows the clamping plates 8 to smoothly clamp and fix the inner side of the tower. Activating the reset switch of the main hydraulic cylinder 1 allows it to drive the main moving plate 5 and the base plate 7 to reset, suspending the tower below the fixing frame 2. Then, activating the switch of the adjusting motor 21 causes it to drive the adjusting screw 14 to rotate via a coupling. The adjusting screw 14, through the screwed auxiliary slider 15, drives the corresponding mounting plate 20 and the spraying assembly 18 to move synchronously, allowing the two sets of spraying assemblies 18 to abut against each other. The structure is circular, with the tower positioned between two sets of spraying components 18. First, the air pump 19 is switched on, injecting airflow into the distributor plate 22 of the spraying component 18 via the air supply pipe. This allows the airflow to pass through the inner cavity of the distributor plate 22 and exit through the jet nozzles, impacting the surface of the tower. Then, the valve of the injection pipe is opened, allowing paint to be injected into the partition plate 23 of the spraying component 18. The paint in the partition plate 23 is then sprayed onto the surface of the tower through the nozzle. Next, the auxiliary motor 16 is switched on, driving the auxiliary lead screw 10 to rotate at low speed via a coupling. The auxiliary lead screw 10 is connected to the main slider 12 via a screw. The auxiliary moving plate 13, mounting plate 20, air pump 19, and spraying assembly 18 move synchronously, enabling the spraying assembly 18 to perform uniform spraying on the tower surface. The air jets on the side of the diverter plate 22 in the forward direction can pre-treat the tower surface, reducing the chance of residual dust or debris and improving the spraying effect on the tower surface. The air jets on the other side of the diverter plate 22 can air-dry the paint sprayed on the tower surface, improving the efficiency of the tower spraying and thus effectively improving the processing efficiency of the tower and reducing the labor intensity of workers.

[0019] In a preferred embodiment, the end face of the fixed frame 2 is U-shaped, and three sets of main hydraulic cylinders 1 are fixedly connected at equal intervals on the upper surface of the fixed frame 2. The lifting plate 3, which is fixedly connected to the main hydraulic cylinders 1, is U-shaped, and the end face of the lifting plate 3 is fixedly connected to the main motor 17. At the same time, two sets of guide rods fixedly connected to the lower surface of the lifting plate 3 are located on both sides of the main lead screw 4.

[0020] In this embodiment, as Figure 1 and Figure 2, The setting of the guide rod can assist in enhancing the stability of the connection between the lifting plate 3 and the main moving plate 5, thereby reducing the probability of accidental bending deformation of the main screw rod 4, and ensuring that the substrate 7 and the clamping plate 8 can smoothly suspend the tower barrel stably.

[0021] As a preferred embodiment, the main moving plate 5 has a rectangular structure. Guide holes are correspondingly opened at both ends of the main moving plate 5 at positions relative to the guide rod. The reinforcing plate 6 fixedly connected to the lower end of the main moving plate 5 has an isosceles trapezoidal structure, and the substrate 7 fixedly connected to the reinforcing plate 6 has a rectangular structure.

[0022] In this embodiment, as shown in Figure 1 and Figure 2 , the structural setting of the reinforcing plate 6 can effectively enhance the firmness of the connection between the main moving plate 5 and the substrate 7, reduce the probability of accidental fracture between the main moving plate 5 and the substrate 7, and ensure the safety of the suspended tower barrel.

[0023] As a preferred embodiment, two groups of through grooves are symmetrically opened on the surface of the substrate 7. Both groups of through grooves have a rectangular structure. The clamping plate 8 slidably connected in the through groove has a cross-shaped structure. A positioning block is fixedly connected to the side of the clamping plate 8 away from the auxiliary hydraulic cylinder 9. At the same time, one end of the clamping plate 8 close to the positioning block has an arc-shaped structure.

[0024] In this embodiment, as shown in Figure 1 and Figure 2 , the sizes of the through grooves and the clamping plate 8 are adapted to each other, which can assist in enhancing the structural strength of the connection between the substrate 7 and the clamping plate 8. The double telescopic rod structure of the auxiliary hydraulic cylinder 9 can ensure that the two clamping plates 8 can move relatively or away from each other synchronously, thereby assisting in improving the stability of the clamping and fixing of the tower barrel by the clamping plate 8. And the setting of the positioning block can also assist in reducing the probability of accidental deviation of the tower barrel.

[0025] As a preferred embodiment, the guide plate 11 has an overall I-shaped structure. A sub-motor 16 is fixedly connected to one end of the upper surface of the guide plate 11. The cross-section of the guiding part in the middle of the guide plate 11 has a swan-neck shape structure. Guide grooves are correspondingly opened on the lower surface of the sub-moving plate 13 at positions relative to the guide plate 11. The sizes of the guide grooves and the guiding part of the guide plate 11 are adapted to each other.

[0026] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the sizes of the guide plate 11 and the guide grooves are adapted to each other, and then it can assist in enhancing the stability of the sub-moving plate 13 when moving on the surface of the guide plate 11, avoiding the problem of accidental tipping during the movement of the sub-moving plate 13, the mounting plate 20 and the spraying component 18, and ensuring the spraying effect of the spraying component 18 on the tower barrel.

[0027] In a preferred embodiment, the auxiliary moving plate 13 has an overall U-shaped structure, and the adjustment motor 21 is fixedly connected to the outer side of the auxiliary moving plate 13. The auxiliary slider 15, which is slidably connected inside the auxiliary moving plate 13, has a rectangular structure. The mounting plate 20, which is fixedly connected to the upper surface of the auxiliary slider 15, has a right-angled trapezoidal structure, and the inclined surface of the mounting plate 20 has an arc-shaped structure.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The dimensions of the inner cavity of the auxiliary moving plate 13 and the auxiliary slider 15 are matched, which can help enhance the stability of the mounting plate 20 and the spraying assembly 18 when they move. The width of the mounting plate 20 is equal to the width of the auxiliary moving plate 13, which can further enhance the stability of the mounting plate 20 and the spraying assembly 18 when they move. The arc structure of the mounting plate 20 can help enhance the fixing effect of the spraying assembly 18.

[0029] In a preferred embodiment, the spraying assembly 18 consists of a flow divider 22 and a partition plate 23. Both the flow divider 22 and the partition plate 23 have a semi-circular structure. The cross-section of the flow divider 22 is U-shaped, and the cross-section of the partition plate 23 is U-shaped. The injection pipe is connected to the inner cavity of the partition plate 23, and the air supply pipe of the air pump 19 is connected to the inner cavity of the flow divider 22. At the same time, multiple sets of nozzles are fixedly connected at equal intervals around the inner side of the flow divider 22. The nozzles are connected to the inner cavity of the partition plate 23. Multiple sets of air jet holes are opened at equal intervals on both sides of the inner arc surface of the partition plate 23. The air jet holes are connected to the inner cavity of the flow divider 22.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The combination of the flow divider 22 and the partition plate 23 allows gas to flow inside the flow divider 22 and paint to flow inside the partition plate 23. This enables the spraying assembly 18 to spray airflow and paint onto the tower surface respectively. As the spraying assembly 18 moves, it can sequentially perform three processing steps on the tower surface: pretreatment cleaning, paint spraying, and paint drying, thereby improving the processing efficiency of the equipment on the tower.

[0031] This utility model's multi-station tower surface pretreatment and spraying integrated equipment, through the cooperation of lifting plate 3, guide plate 11, base plate 7, clamping plate 8, auxiliary moving plate 13 and spraying component 18, enables the equipment to perform corresponding pretreatment and spraying treatment on the tower surface, thereby improving the spraying quality and efficiency of the tower surface, increasing the equipment's processing efficiency for the tower, and reducing the labor intensity of workers.
