Description

Technical Field

[0001] This invention relates to the field of spray painting and renovation equipment technology, and in particular to an automated spray painting and renovation device for the exterior of a gas station. Background Technology

[0002] After long-term use, the paint on the exterior of a gas station will show signs of weathering and peeling, requiring repainting and renovation. Due to the height of the roof, mechanical equipment is usually needed for the painting process.

[0003] Chinese patent document CN116174194A discloses an automated spraying and renovation device for the exterior of a gas station. This device is equipped with an anti-displacement mechanism, which prevents the spray nozzle from being affected when the base shifts during movement. The spray nozzle is always parallel to the exterior of the gas station, resulting in more uniform and comprehensive spraying and improving the spraying effect. However, in actual use, the device is not equipped with a cleaning device for the exterior of the gas station, which may affect the spraying of the gas station exterior and lead to poor spraying effect. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this invention, by setting a limiting device, before spraying and renovating the exterior of the gas station, the limiting rod in the limiting device needs to drive the roller to contact the upper and lower surfaces of the gas station exterior, so that the upper and lower rollers clamp the gas station exterior, avoiding poor painting effect due to the shaking caused by the movement of the moving base during the painting process, thus improving the stability of the device.

[0017] 2. In this invention, by providing a driven device, during the movement of the movable base according to the set route, the driven device uses the power generated when the two rollers located at the top come into contact with the exterior of the gas station to drive the slide rail to reciprocate, thereby causing the slide rail to drive the cleaning mechanism to move, avoiding the need to set up a corresponding power source and reducing the manufacturing cost of the device.

[0018] 3. In this invention, a cleaning mechanism is provided. Driven by the driven device, the bucket in the cleaning mechanism will remove the impurities adhering to the exterior of the gas station. At the same time, the nylon brush will clean the dust on the exterior of the gas station to avoid affecting the spraying effect of the painting device on the exterior of the gas station.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1

[0033] like Figure 1 As shown, this embodiment discloses an automated spraying and renovation device for the exterior of a gas station, including a movable base 1. A lifting rod 2 is provided at the upper middle part of the movable base 1. Support plate 3 and support plate 4 are respectively provided on the upper two sides of the outer surface of the lifting rod 2. Limiting devices 5 are provided on both sides of the outer surface of support plate 4. A painting device 8 is provided on one side of the outer surface of support plate 3. A storage box 9 for storing dye is provided on one side of the upper end of the movable base 1.

[0034] Specifically, the mobile base 1 can operate automatically according to the set route, and the lifting rod 2 can be raised and lowered according to the height of the gas station facade, thereby pushing the corresponding spraying and renovation equipment to the required working height. The mobile base 1 and the lifting rod 2 are existing technologies, and will not be described in detail in this manual.

[0035] Before repainting the exterior of the gas station, the painting equipment needs to be restricted to avoid poor painting results due to shaking caused by the moving base 1 during the painting process. Figure 2 and Figure 3 As shown, the limiting device 5 includes two limiting frames 51, which are fixedly installed on both sides of the outer surface of the support plate 2 4. Limiting rods 52 are provided on the upper and lower sides of the two limiting frames 51. The outer surfaces of the four limiting rods 52 are slidably installed in the inner cavities of the two limiting frames 51 on the side closest to the support plate 2 4. Rollers 53 are provided on the outer surfaces of the four limiting rods 52 away from the support plate 2 4, and the rollers 53 on the upper and lower sides are arranged opposite each other. A driven mechanism 54 is provided at the upper end of the two upper limiting rods 52. A braking mechanism 55 is provided on the side of the outer surfaces of the two limiting frames 51 that are close to each other.

[0036] Specifically, before the gas station facade is painted and renovated, the lifting rod 2 will push the relevant equipment to the corresponding height through the support plate 1 3 and support plate 2 4. During this process, the braking mechanism 55 will drive the four limit rods 52 on the upper and lower sides to move away from the limit frame 51. Then, the moving base 1 will drive the entire device to move closer to the gas station facade, so that the rollers 53 on the surface of the limit rods 52 on the upper and lower sides are aligned with the upper and lower surfaces of the gas station facade. After that, the braking mechanism 55 will drive the limit rods 52 on the upper and lower sides to move closer to the limit frame 51 in the opposite direction, so that the rollers 53 on the surface of the four limit rods 52 contact the upper and lower surfaces of the gas station facade respectively. When the moving base 1 moves according to the set route, the four rollers 53 will move on the surface of the gas station facade. In this way, the problem of poor painting effect caused by the shaking of the moving base 1 during the painting process can be avoided.

[0037] The braking mechanism 55 drives the limiting rods 52 on both sides to move, causing the limiting rods 52 on the upper and lower sides to drive the four rollers 53 to contact the upper and lower ends of the gas station's exterior facade, thereby restricting the spray painting and renovation device. Figure 3 As shown, the braking mechanism 55 includes a support housing 551, which is fixedly installed on the outer surface of the second support plate 4 away from the first support plate 3. A motor 552 is installed in the middle of the inner cavity of the support housing 551. A transmission rod 553 is installed on both sides of the inner cavity of the support housing 551. The two transmission rods 553 are connected to the motor 552 through a bevel gear set. The ends of the two transmission rods 553 that are far apart from each other extend into the inner cavity of the limiting frame 51. A screw 554 is installed on the side of the two transmission rods 553 that are far apart from each other. The two screws 554 are rotatably installed in the inner cavities of the two limiting frames 51 respectively. The two screws 554 are connected to the two transmission rods 553 respectively through two worm gear mechanisms. The two outer surfaces of the two screws 554 are threaded to the inner walls of the four limiting rods 52 respectively. The threads on the two outer surfaces of the two screws 554 are opposite.

[0038] Specifically, when the upper and lower limit rods 52 need to move away from the limit frame 51, the motor 552 drives the screws 554 on both sides to rotate simultaneously through the transmission rod 553. Since the screws 554 have threads in opposite directions on their surfaces, when the screws 554 on both sides rotate, they will simultaneously drive the upper and lower limit rods 52 to move away from the limit frame 51.

[0039] Furthermore, when it is necessary for the upper and lower limit rods 52 to move towards the side closer to the limit frame 51 so that the roller 53 contacts the surface of the gas station facade, the motor 552 drives the screws 554 on both sides to rotate in the opposite direction, thereby causing the upper and lower limit rods 52 to move towards the side closer to the limit frame 51.

[0040] After the spray painting and renovation equipment is fully secured, the exterior of the gas station can be painted using the spray painting device 8, such as... Figure 4 As shown, the painting device 8 includes a positioning shell 81, which is fixedly installed on one side of the outer surface of the support plate 3. A painting mechanism 82 is provided in the middle of the inner cavity of the positioning shell 81. Multiple nozzles 83 are provided on the outer surface of the painting mechanism 82 away from the support plate 4. A collection funnel 84 is provided at the lower end of the positioning shell 81. A collection box 85 is provided at the lower end of the collection funnel 84. The inner cavity of the collection funnel 84 communicates with the inner cavity of the collection box 85. A conveying pipe 86 is fixedly installed at the lower end of the painting mechanism 82. The lower end of the conveying pipe 86 is connected to the output pipe of the storage box 9. The upper part of the outer surface of the conveying pipe 86 is fixedly connected to the inner wall of the collection funnel 84.

[0041] Specifically, when the limit rods 52 on both sides drive the four rollers 53 to contact the surface of the gas station facade, the painting mechanism 82 will introduce the paint dye in the storage box 9 into multiple nozzles 83 through the delivery pipe 86, so that the multiple nozzles 83 can spray the dye onto the surface of the gas station facade.

[0042] Furthermore, during the spraying process of the gas station's exterior facade, some dye will flow down from the surface of the gas station's exterior facade. The flowing dye will enter the inner cavity of the collection funnel 84 and finally flow into the inner cavity of the collection box 85 for collection.

[0043] Furthermore, since the collecting funnel 84 is connected to the lower end of the positioning shell 81, and after the limiting device 5 contacts the exterior of the gas station, the connection points of the two rollers 53 at the lower part with the exterior of the gas station are higher than the upper end of the collecting funnel 84. Therefore, the collecting funnel 84 can extend to the lower part of the exterior of the gas station, which facilitates the collection of the flowing dye.

[0044] Example 2

[0045] This embodiment further improves the driven mechanism 54 in the limiting device 5 based on Embodiment 1, such as... Figure 1 As shown, a driven device 7 is provided on the other side of the outer surface of the support plate 3, and a cleaning mechanism 6 is provided on the side of the outer surface of the driven device 7 away from the support plate 4.

[0046] When the movable base 1 moves, in order to transmit the power generated by the movement of the movable base 1 to the driven device 7, so that the driven device 7 can operate, as follows: Figure 5 and Figure 6 As shown, the driven mechanism 54 includes a driven rod 541, which is rotatably mounted on the upper end of two limit rods 52 located at the top. Both sides of the outer surface of the driven rod 541 are provided with transmission components 542, and the two transmission components 542 are respectively connected to the two rollers 53 located at the top through a belt drive mechanism.

[0047] Specifically, since the limit rod 52 drives the roller 53 to make close contact with the surface of the gas station facade, when the movable base 1 moves along the predetermined route, the roller 53 will rotate under the action of friction between it and the gas station facade, thereby causing the two rollers 53 located at the top to drive the driven rod 541 to rotate through the two transmission components 542 respectively.

[0048] Furthermore, the transmission component 542 consists of a bevel gear set and a transmission rod, which is connected to the central shaft of the roller 53 via a belt drive mechanism.

[0049] Over time, the exterior of a gas station may accumulate impurities and dust, requiring removal and cleaning to ensure a good finish on the paint job. Figure 7 As shown, the driven device 7 includes two slide rails 71, and a driven rod 72 for transmission is provided between the two slide rails 71. The upper end of the driven rod 72 extends to the outside of the upper slide rail 71. A reciprocating mechanism 74 is provided at the upper end of the driven rod 72, and a transmission telescopic rod 73 is provided at the upper end of the reciprocating mechanism 74. The upper end of the transmission telescopic rod 73 is connected to the middle of the outer surface of the driven rod 541 through a bevel gear set.

[0050] Specifically, when the driven rod 541 rotates, the transmission telescopic rod 73 will rotate under the drive of the bevel gear set, which in turn will drive the reciprocating mechanism 74 to rotate, thereby causing the reciprocating mechanism 74 to drive the sliders on the two slide rails 71 to reciprocate through the driven rod 72.

[0051] Furthermore, since the driven rod 541 moves with the two limit rods 52 located at the top, but since an L-shaped connecting plate is provided between the transmission telescopic rod 73 and the driven rod 541, the driven rod 541 will pull the transmission telescopic rod 73 to extend and retract when it moves up and down, without affecting the driven rod 541 driving the transmission telescopic rod 73 to rotate.

[0052] Furthermore, the slide rail 71 is existing technology, which drives the drive shaft on it to rotate, thereby causing the drive shaft to drive the slider on it to move through the belt drive mechanism.

[0053] In order to enable the slide rail 71 to drive the cleaning mechanism 6 to reciprocate, and thus enable the cleaning mechanism 6 to more thoroughly clean the impurities and dust on the exterior of the gas station, such as... Figure 8 and Figure 9 As shown, the reciprocating mechanism 74 includes a support plate 741, which is fixedly installed on the upper end of the positioning housing 81. Two gears 742 are provided on the upper end of the support plate 741 and are meshed together. Multiple brake rods 743 are provided on the upper end of each of the two gears 742. A non-circular gear 744 is provided between the gears 742 and is rotatably connected to the upper end of the support plate 741. The non-circular gear 744 is adapted to the multiple brake rods 743 on the two gears 742. The upper end of the gear 742 located away from the slide rail 71 is fixedly connected to the lower end of the transmission telescopic rod 73. A spur gear set 745 is provided on the lower end of the support plate 741. The spur gear set 745 consists of a large spur gear and a small spur gear. The upper middle part of the large spur gear in the spur gear set 745 is fixedly connected to the inner surface of the non-circular gear 744. The lower middle part of the small spur gear in the spur gear set 745 is fixedly connected to the upper end of the driven rod 72.

[0054] Specifically, when the transmission telescopic rod 73 rotates under the drive of the driven rod 541, the transmission telescopic rod 73 first drives the gear 742 located on the side away from the slide rail 71 to rotate. Since the two gears 742 are meshed, they will simultaneously drive the gear 742 on the other side to rotate. When the two gears 742 rotate at the same time, the multiple brake rods 743 on the surface of the two gears 742 will alternately contact the surface of the irregular gear 744.

[0055] Furthermore, since the two gears 742 are meshed and connected, they rotate in opposite directions. When multiple gears 742 on the two gears 742 alternately contact the surface of the shaped gear 744, they will drive the shaped gear 744 to reciprocate. This causes the shaped gear 744 to drive the sliders on the two slide rails 71 to reciprocate through the spur gear set 745 and the driven rod 72.

[0056] In order to remove and clean the impurities and dust on the exterior of the gas station, such as Figure 10 As shown, the cleaning mechanism 6 includes a connecting plate 61, which is fixedly installed on the surface of the slider on the two slide rails 71. A nylon brush 62 is provided on one side of the outer surface of the connecting plate 61, and a bucket 63 is provided on the other side of the outer surface of the connecting plate 61.

[0057] Furthermore, such as Figure 11 As shown, the connection between the connecting plate 61, the nylon brush 62, and the bucket 63 is connected by an elastic telescopic rod.

[0058] Specifically, due to the accumulation of impurities or dust on the surface of gas station facades over long-term use, it is necessary to clean the gas station facades before spraying them.

[0059] Furthermore, as the braking mechanism 55 drives the four limiting rods 52 on the upper and lower sides to move away from the limiting frame 51, the moving base 1 drives the entire device to move closer to the exterior of the gas station. During the process of moving the device to the corresponding position, the surfaces of the nylon brush 62 and the bucket 63 will first contact the exterior of the gas station. Then, as the moving base 1 continues to drive the entire device to move closer to the exterior of the gas station, the nylon brush 62 and the bucket 63 will compress the elastic telescopic rod at the connection point with the connecting plate 61, so that the surfaces of the nylon brush 62 and the bucket 63 are in close contact with the exterior of the gas station.

[0060] Furthermore, after the surfaces of the nylon brush 62 and the bucket 63 come into close contact with the exterior of the gas station, the slider on the slide rail 71 will drive the nylon brush 62 and the bucket 63 to reciprocate through the connecting plate 61, so that the bucket 63 removes the impurities on the exterior of the gas station. After that, the nylon brush 62 cleans the exterior of the gas station. While the cleaning mechanism 6 is cleaning the exterior of the gas station, the painting device 8 can spray paint on the wall surface that has been cleaned by the cleaning mechanism 6.

[0061] Furthermore, when there are many impurities and dust on the surface of the gas station facade, the facade can be cleaned several times by a cleaning machine before the spraying operation is carried out.

[0062] It should be noted that the specific installation method, circuit layout and connection method, and control method of the movable base 1, lifting rod 2, motor 552, painting mechanism 82 and spray head 83 used in the above embodiment are all conventional designs in the prior art, and will not be described in detail in this invention.

[0063] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
