Description

Technical Field

[0001] This invention relates to the technical field of apron painting equipment, and more specifically, to apron pipeline well marker painting equipment. Background Technology

[0002] Airport pipeline wells include refueling hydrant wells, valve wells, and leak detection wells. Different wells require different paints. Manual painting is time-consuming, inefficient, and costly. Furthermore, manual painting makes it difficult to effectively observe the apron environment and carries the risk of injury from collisions with apron vehicles. Bending over to paint can easily damage personnel's backs and may result in the inhalation of large amounts of toxic fumes, leading to poisoning. After painting, personnel may leave tools on the apron, creating FOD (Foreign Object Debris). Additionally, different wells have different identification zones, which are typically painted with different patterns using different colors of paint.

[0003] Existing technology discloses a ground marking device for an aluminum electrolysis workshop, including a vehicle body and a spray gun. The spray gun is mounted on the vehicle body at a position where it can be aimed at the ground. A paint pump is installed on the vehicle body, and the paint pump is connected to a paint storage mechanism. The spray gun is connected to the paint pump. A linkage mechanism is installed on the vehicle body, with one end of the linkage mechanism connected to the trigger of the spray gun and the other end connected to a handle. Pulling the linkage mechanism via the handle forms a control structure for the trigger. In this solution, the paint pump draws paint from a paint bucket and automatically sprays the paint onto the ground through the spray gun. This solution relies on manual pushing and walking to create the marking pattern along the walking path, but it cannot be applied to painting different colored icons for apron pipeline wells. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technology in that it cannot be used for painting different colored icons on apron pipeline wells, and to provide an apron pipeline well icon painting device that can spray different colored paints on the marked areas of apron pipeline wells to form icon markings.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A spray painting device for apron pipeline well icons is provided, including a frame and a first spray painting module, a moving module, and a template module mounted on the frame. The first spray painting module has at least two sets. Each set of the first spray painting module includes a first paint bucket, a first paint inlet pipe, a first sprayer, a first paint outlet pipe, and a first spray gun. The first paint bucket and the first sprayer are mounted on the frame. The first paint bucket is connected to one end of the first sprayer through the first paint inlet pipe, and the other end of the first sprayer is connected to the first spray gun. The output end of the moving module is connected to the first spray gun. The moving module drives the first spray gun to move in a horizontal plane. The template module includes a first template, a second template, and at least two lifting rods. The first template has a first icon opening, and the second template has a second icon opening. One end of each lifting rod is connected to the frame, and the other end is connected to the first template. The second template is detachably installed on top of the first template, and the first spray gun is located above the second template.

[0006] The apron pipeline well icon painting equipment of the present invention, in use, involves filling the first paint buckets of two sets of first painting modules with paint of different colors. The frame is placed at a specific location on the pipeline well, with the template module facing the marking area of ​​the well. The second template is removed, leaving the bottom of the first template in contact with the ground. Paint of the first color is sprayed through the first spray gun of one set of first painting modules. A moving module moves the first spray gun, forming a first icon of the first color through the first icon opening. Then, a second module is installed on top of the first modules, and paint of the second color is sprayed through the first spray gun of the other set of first painting modules. A moving module moves the first spray gun, forming a second icon of the second color on the first icon through the second icon opening, thus completing the icon painting of the apron pipeline well and marking the well with icons. It should be noted that in this invention, the second template can be replaced to allow for painting different icons on different pipeline wells.

[0007] Furthermore, the moving module is a linear translation module, and also includes a mounting platform. The output end of the linear translation module is fixedly connected to the mounting platform, and the first spray gun is mounted on the mounting platform.

[0008] Furthermore, a rubber pad is provided at the bottom of the first template.

[0011] Furthermore, it also includes a second painting module, a second lifting frame, a hollow rotating platform, and a support frame. The second painting module includes a second paint bucket, a second paint inlet pipe, a second sprayer, a second paint outlet pipe, and a second spray gun. The second paint bucket and the second sprayer are mounted on the frame. The second paint bucket is connected to one end of the second sprayer through the second paint inlet pipe, and the other end of the second sprayer is connected to the second spray gun. The second spray gun is mounted on the support frame. The second lifting frame is mounted on the frame. The hollow rotating platform is mounted on the second lifting frame. The second paint outlet pipe passes through the hollow rotating platform. The output end of the hollow rotating platform is connected to the support frame. The hollow rotating platform drives the support frame to rotate in a horizontal plane.

[0012] Furthermore, it also includes a universal rotary joint and a diverter pipe, the second paint outlet pipe being connected to the second spray gun through the universal rotary joint and the diverter pipe, and the universal rotary joint being connected between the second paint outlet pipe and the diverter pipe.

[0013] Furthermore, the second spray gun is provided with paint blocking components on both sides. The paint blocking components include a baffle, a guide rod and a spring. The baffle has a guide groove. The top of the guide rod is fixedly connected to the support frame, and the bottom of the guide rod is slidably connected to the guide groove.

[0026] Example 1

[0027] This embodiment is the first embodiment of the apron pipeline well icon spraying equipment, such as... Figures 1 to 3 As shown, the system includes a frame 1 and a first painting module 2, a moving module 3, and a template module 4 mounted on the frame 1. The first painting module 2 has at least two sets. Each set of the first painting module 2 includes a first paint bucket 201, a first paint inlet pipe 202, a first sprayer 203, a first paint outlet pipe 204, and a first spray gun 205. The first paint bucket 201 and the first sprayer 203 are mounted on the frame 1. The first paint bucket 201 is connected to one end of the first sprayer 203 via the first paint inlet pipe 202, and the other end of the first sprayer 203 is connected to the first spray gun 205. The moving module 3... The output end is connected to the first spray gun 205. The moving module 3 drives the first spray gun 205 to move in the horizontal plane. The template module 4 includes a first template 401, a second template 402 and at least two hanging rods 403. The first template 401 is provided with a first icon opening 4011, and the second template 402 is provided with a second icon opening 4021. One end of the hanging rod 403 is connected to the frame 1, and the other end of the hanging rod 403 is connected to the first template 401. The second template 402 is detachably installed on the top of the first template 401, and the first spray gun 205 is located above the second template 402.

[0028] The aforementioned apron pipeline well icon painting equipment, in use, fills the first paint buckets 201 of the two sets of first painting modules 2 with paint of different colors. The frame 1 is placed at a specific position on the pipeline well, with the template module 4 facing the marking area of ​​the pipeline well. The second template 402 is removed, and the bottom of the first template 401 contacts the ground. Paint of the first color is sprayed out by the first spray gun 205 of the first painting module 2. The moving module 3 moves the first spray gun 205, forming a first icon of the first color through the first icon opening 4011. Then, a second module is installed on top of the first module, and paint of the second color is sprayed out by the first spray gun 205 of the other set of first painting modules 2. The moving module 3 moves the first spray gun 205, forming a second icon of the second color on the first icon through the second icon opening 4021, thus completing the icon painting of the apron pipeline well and marking the apron pipeline well with icons. It should be noted that in this embodiment, the second template 402 can be replaced to be used for different icons to be sprayed on different pipeline wells.

[0029] The moving module 3 is a linear translation module, and also includes a mounting platform 301. The output end of the linear translation module is fixedly connected to the mounting platform 301. The first spray gun 205 is mounted on the mounting platform 301. Figure 1 , Figure 2 As shown. In implementation, the linear translation module drives the mounting platform 301 and the first spray gun 205 on it to move linearly. Since the first painting module 2 is provided with at least two sets, the linear translation module drives all the first spray guns 205 on the mounting platform 301 to move synchronously, preventing pipeline entanglement from occurring during the movement of the first spray guns 205 of different first painting modules 2.

[0030] The bottom of the first template 401 is equipped with a rubber pad. The rubber pad is a soft rubber pad, which is in contact with the ground. This ensures that the soft rubber pad will deform under gravity and adhere to the ground even if the ground is uneven, so that the sprayed edges are neat and beautiful.

[0031] like Figure 1 As shown, the bottom of the frame 1 is equipped with casters 13. The casters 13 allow the equipment to be easily pushed to the designated position for spraying operations.

[0032] like Figure 1 , Figure 2As shown, the frame 1 is equipped with a first lifting mechanism 5, the output end of which is connected to a first lifting frame 6. The moving module 3 is installed on the first lifting frame 6, and one end of the boom 403 is connected to the first lifting frame 6. During spraying, the bottom of the first template 401 is in contact with the ground. Directly pushing the frame 1 can easily damage the template module 4. Before operation, the first lifting mechanism 5 can be used to drive the first lifting frame 6 and the template module 4 upward, and then the frame 1 can be pushed to the designated position. Then, the first lifting mechanism 5 can be used to drive the first lifting frame 6 and the template module 4 downward, so that the first template 401 contacts the ground for spraying.

[0033] The top of the boom 403 has a protrusion, and the first lifting frame 6 has a sliding sleeve. The top of the boom 403 slides through the sliding sleeve, and the bottom of the protrusion can engage with the top of the sliding sleeve. Figure 2 As shown. During implementation, the template module 4 moves downward under its own action, causing the protrusion to engage with the top of the sliding sleeve. As the first lifting mechanism 5 drives the first lifting frame 6 to move downward, when the first template 401 contacts the ground and the first lifting frame 6 continues to move downward, the hanging rod 403 slides relative to the sliding sleeve. When the ground is uneven, the higher part of the ground supports the first template 401, and the top of the hanging rod 403 at the corresponding position can move upward relative to the sliding sleeve.

[0034] Example 2

[0035] This embodiment is the second embodiment of the apron pipeline well icon spraying equipment. This embodiment is similar to the first embodiment, except that, as Figure 1 , Figure 4As shown, it also includes a second painting module 7, a second lifting frame 11, a hollow rotating platform 8, and a support frame 12. The second painting module 7 includes a second paint bucket 701, a second paint inlet pipe 702, a second sprayer 703, a second paint outlet pipe 704, and a second spray gun 708. The second paint bucket 701 and the second sprayer 703 are mounted on the frame 1. The second paint bucket 701 is connected to one end of the second sprayer 703 through the second paint inlet pipe 702. The other end of the second sprayer 703 is connected to the second spray gun 708. The second spray gun 708 is mounted on the support frame 12. The second lifting frame 11 is mounted on the frame 1. The hollow rotating platform 8 is mounted on the second lifting frame 11. The second paint outlet pipe 704 passes through the hollow rotating platform 8. The output end of the hollow rotating platform 8 is connected to the support frame 12. The hollow rotating platform 8 drives the support frame 12 to rotate in the horizontal plane. During implementation, the frame 1 is placed at a specific location in the pipeline well, and the second spray gun 708 is aimed at the painting position, namely the warning area on the outer periphery of the well cover. The second paint sprayer 703 draws paint from the second paint bucket 701 and supplies paint to the second spray gun 708. The paint is sprayed from the second spray gun 708 to the warning area. At the same time, the hollow rotating platform 8 controls the support frame 12 and the second spray gun 708 on it to rotate in the horizontal plane. The second spray gun 708 rotates and sprays paint to form the warning area, realizing automatic painting of the warning area of ​​the apron pipeline well.

[0036] like Figure 1 , Figure 4 As shown, it also includes a universal rotary joint 705 and a diverter pipe 707. The second paint outlet pipe 704 is connected to the second spray gun 708 through the universal rotary joint 705 and the diverter pipe 707, and the universal rotary joint 705 is connected between the second paint outlet pipe 704 and the diverter pipe 707. When the hollow rotating platform 8 controls the support frame 12 and the second spray gun 708 on it to rotate, the diverter pipe 707 rotates with the second spray gun 708. The universal rotary joint 705 can support the unrestricted rotation of the support frame 12, ensuring that the pipe is not tangled or knotted.

[0037] like Figure 4 As shown, it also includes a three-way connector 706, two diverter pipes 707, and two second spray guns 708. One port of the three-way connector 706 is connected to the second paint outlet pipe 704 via a universal swivel joint 705. The remaining two ports of the three-way connector 706 are connected to the second spray guns 708 via the two diverter pipes 707, respectively. The two second spray guns 708 are symmetrically arranged about the rotation center axis of the hollow rotating platform 8. In implementation, the two second spray guns 708 are respectively installed at both ends of the support frame 12. The two second spray guns 708 are balanced with each other, which can improve the painting efficiency.

[0038] like Figure 4As shown, the hollow rotating platform 8 includes a base 801, a motor 802, and a hollow turntable 803. The base 801 is fixedly connected to the second lifting frame 11. The motor 802 is mounted on the base 801, and its output end is connected to the hollow turntable 803. The hollow turntable 803 is connected to the support frame 12, and the second paint outlet pipe 704 passes through the hollow turntable 803. In operation, the motor 802 drives the hollow turntable 803 to rotate, which in turn drives the support frame 12 and its second spray gun 708 to rotate and spray paint, thereby achieving automatic painting of the warning area of ​​the pipeline well.

[0039] Example 3

[0040] This embodiment is the third embodiment of the apron pipeline well icon spraying equipment. This embodiment is similar to embodiment two, except that, as shown in the example... Figure 1 , Figure 4 and Figure 5 As shown, the second spray gun 708 is provided with paint blocking components 9 on both sides. The paint blocking components 9 include a baffle 901, a guide rod 902 and a spring 903. The baffle 901 has a guide groove 9011. The top of the guide rod 902 is fixedly connected to the support frame 12, and the bottom of the guide rod 902 is slidably connected to the guide groove 9011. The spring 903 is wound around the guide rod 902, and the two ends of the spring 903 are respectively connected to the support frame 12 and the baffle 901. Specifically, the bottom of the baffle 901 is provided with a guide slope 9012. When the hollow rotating platform 8 drives the support frame 12 and its components to rotate for automatic painting, if the ground is relatively flat, the baffle 901 approaches the ground under its own weight to ensure that the painted edges are neat. If the ground is uneven, at the protrusions, the guide slope 9012 contacts the ground first, and the ground presses against the baffle 901. Under the sliding cooperation of the guide rod 902 and the guide groove 9011, the baffle 901 moves along the guide rod 902 to compress the spring 903. At the depressions, the baffle 901 moves downward under the force of the spring 903. The baffle 901 is always in contact with the ground to ensure that the painted edges are neat.

[0041] like Figure 1 , Figure 4 As shown, it also includes a second lifting mechanism 10, which is mounted on the frame 1. The output end of the second lifting mechanism 10 is connected to the second lifting frame 11. During the painting operation, the hollow rotating platform 8 drives the support frame 12 and the paint blocking component 9 on it to rotate and rub against the ground to ensure a neat sprayed edge. Before the operation, the device needs to be pushed to the working position. During this process, the paint blocking component 9 is easily worn. The second lifting mechanism 10 drives the second lifting frame 11 and its components to move upward, which can prevent damage to the equipment during the pushing process. After the frame 1 is pushed to the working position, the lifting mechanism can drive the second lifting frame 11 and its components to move downward, so that the paint blocking component 9 can function normally and ensure a neat sprayed edge.

[0042] like Figure 1 As shown, the system also includes a control system 14. The first lifting mechanism 5, the moving module 3, the first sprayer 203, the second lifting mechanism 10, the hollow rotating platform 8, and the second sprayer 703 are all communicatively connected to the control system 14. During implementation, the control system 14 can control the first lifting mechanism 5 and the second lifting mechanism 10 to prevent damage to the equipment during the pushing process of the frame 1. The control system 14 can also control the first lifting mechanism 5 and the second lifting mechanism 10 to move in opposite directions to meet the spraying height requirements. The control system 14 can control the first sprayer 203 and the second sprayer 703 to perform painting. The control system 14 can also control the moving module 3 and the hollow rotating platform 8 to automatically adjust the spraying position. It should be noted that the control system 14 includes mechanical buttons and a touch screen, allowing switching between touch control mode and button control mode.

[0043] The first paint outlet pipe 204 is equipped with a first pressure gauge, and the second paint outlet pipe 704 is equipped with a second pressure gauge. The pressure gauges can be used to observe whether the spraying pressure meets the operational requirements, and the pressure can be adjusted to observe whether the required pressure is reached.

[0044] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
