The first paint bucket 201 and the first sprayer 203 are installed on the frame 1. The first paint bucket 201 is connected to one end of the first sprayer 203 through the first paint inlet pipe 202, and the other end of the first sprayer 203 is connected to the first spray gun 205. The mobile module 3 The output end is connected to the first spray gun 205, the mobile 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 suspension rods 403, the first template 401 is provided with a first icon opening 4011, the second template 402 is provided with a second icon opening 4021, one end of the suspension rod 403 is connected to the frame 1, and the other end of the suspension 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.

[0022] When the above-mentioned apron pipeline well icon painting equipment is used, different colors of paint are respectively contained in the first paint buckets 201 of the two groups of first paint spray modules 2, the frame 1 is placed at a specific position of the pipeline well, the template module 4 is facing the identification area of ​​the pipeline well, the second template 402 is removed, the bottom of the first template 401 contacts the ground, and the first spray gun 205 of a group of first paint spray modules 2 sprays paint with a first color, the mobile module 3 drives the first spray gun 205 to move, and forms a first icon with a first color through the first icon opening 4011, and then the second module is installed on the top of the first module, and the first spray gun 205 of another group of first paint spray modules 2 sprays paint with a second color, the mobile module 3 drives the first spray gun 205 to move, and forms a second icon with a second color on the first icon through the second icon opening 4021, thereby completing the icon painting of the apron pipeline well and marking the apron pipeline well with an icon. It should be noted that, in this embodiment, the second template 402 can be replaced so as to be used for spraying different icons on different pipeline wells.

[0023] 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 installed on the mounting platform 301. Figure 1 , Figure 2During implementation, the linear translation module drives the mounting platform 301 and the first spray guns 205 thereon to move linearly.

During implementation, the frame 1 is placed at a specific position in the pipeline well, and the second spray gun 708 is aimed at the painting position, that is, the warning area around the well cover. The second 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 thereon to rotate in the horizontal plane. The second spray gun 708 rotates to spray paint to form a warning area, thereby realizing automatic painting of the warning area of ​​the apron pipeline well.

[0029] like Figure 1 , Figure 4 As shown, it also includes a universal rotating joint 705 and a shunt pipe 707. The second paint outlet pipe 704 is connected to the second spray gun 708 through the universal rotating joint 705 and the shunt pipe 707, and the universal rotating joint 705 is connected between the second paint outlet pipe 704 and the shunt pipe 707. When the hollow rotating platform 8 controls the support frame 12 and the second spray gun 708 thereon to rotate, the shunt pipe 707 rotates with the second spray gun 708, and the universal rotating joint 705 can support the support frame 12 to rotate without restriction, ensuring that the pipeline is wound and knotted.

[0030] like Figure 4 As shown, it also includes a three-way joint 706, two shunt pipes 707, and two second spray guns 708. One interface of the three-way joint 706 is connected to the second paint outlet pipe 704 through a universal rotating joint 705, and the remaining two interfaces of the three-way joint 706 are respectively connected to the second spray gun 708 through two shunt pipes 707, and the two second spray guns 708 are symmetrically arranged about the rotation center axis of the hollow rotating platform 8. During implementation, the two second spray guns 708 are respectively installed at both ends of the support frame 12, and the two second spray guns 708 are balanced with each other, and the painting efficiency can be improved.

Specifically, a guide slope 9012 is provided at the bottom of the baffle 901. When the hollow rotating platform 8 drives the support frame 12 and the components thereon to rotate for automatic spray painting, if the ground is relatively flat, the baffle 901 approaches the ground under the action of its own gravity to ensure that the spraying edge is neat; if the ground is uneven, at the protrusion, the guide slope 9012 first contacts the ground, and the ground squeezes 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 squeeze the spring 903. At the pit, the baffle 901 moves downward under the action of the spring 903. The baffle 901 is always in contact with the ground to ensure that the spraying edge is neat.

[0033] like Figure 1 , Figure 4 As shown, it also includes a second lifting mechanism 10, which is installed on the frame 1, and the output end of the second lifting mechanism 10 is connected to the second lifting frame 11.
