Those skilled in the art can make some non-essential improvements and adjustments to the present invention according to the above application content.

[0033] Embodiment:

[0034] As Figure 1 , 2As shown in the figure, the present utility model provides an automatic spraying device for a circular pipe, which includes a spraying ring 101, with multiple groups of connected nozzles 102 arranged at the bottom. All the multiple groups of nozzles 102 are oriented towards the axis of the spraying ring 101. The spraying ring 101 is externally connected to a feeding device. Multiple groups of first mounting brackets 104 are arranged circumferentially on the spraying ring 101. A support rod 301 is slidably arranged in each of the multiple groups of first mounting brackets 104. A traveling wheel 305 controlled to rotate by a motor is arranged at the end of the support rod 301.

[0035] When the spraying device is in use, the device is sleeved on the circular pipe to be sprayed, and all the multiple groups of traveling wheels 305 are made to abut against the outer wall of the circular pipe. Then, multiple groups of motors are started to control the rotation of the traveling wheels 305. Among them, the motor can also be replaced by an electric motor, which is selected according to the actual size and the weight of the device. The rotation of the traveling wheels 305 can drive the spraying device to travel along the axis of the circular pipe, and the feeding device is used to supply materials to the nozzles 102, and the outer wall of the circular pipe is sprayed through the nozzles 102 to achieve the purpose of automatic spraying, effectively reducing the working intensity.

[0036] As Figure 1 、 2 shown in the figure, in this embodiment, an adjusting component is arranged on the spraying ring 101 and is connected to one of the support rods 301. The support rod 301 is driven to slide through the adjusting component. The adjusting component includes a second mounting bracket 105 arranged on the spraying ring 101. A threaded rod 401 that can rotate along its axis is arranged at the end of one of the support rods 301. The threaded rod 401 is screwed on the second mounting bracket 105, and a knob 402 is arranged at the end of the threaded rod 401.

[0037] Among them, the position of one of the traveling wheels 305 can be adjusted by rotating the knob 402 to drive the threaded rod 401 to slide along its axis on the second mounting bracket 105. And a handle 103 is arranged on the spraying ring 101. The arrangement of the handle 103 facilitates the adjustment and carrying of the device, improving the convenience of using the device.

[0038] As Figure 2 、 3 shown in the figure, in this embodiment, a linkage component is arranged on one of the support rods 301 and is connected to the other groups of support rods 301. The multiple groups of support rods 301 are driven to slide synchronously through the linkage component. The linkage component includes the same number of linkage columns 302 as the support rods 301. The linkage columns 302 are arranged on the support rods 301. A driving disk 201 that can rotate is arranged on the spraying ring 101. Multiple groups of guiding grooves 202 are circumferentially formed on the driving disk 201. The guiding grooves 202 are arranged in a staggered manner with the radial lines of the driving disk 201 and are not perpendicular. The multiple groups of linkage columns 302 are respectively slidably clamped in the multiple groups of guiding grooves 202.

[0039] During the process of driving one set of support rods 301 to slide along their axes by rotating the threaded rod 401, the driving disk 201 is driven to rotate through the cooperation between the linkage columns 302 on this set of support rods 301 and one set of guide grooves 202. During the rotation of the driving disk 201, the remaining sets of support rods 301 can be controlled to slide synchronously through the cooperation between the other sets of guide grooves 202 and the linkage columns 302, so that multiple sets of support rods 301 all slide towards the axis of the spraying ring 101 to adjust the distance between multiple sets of traveling wheels 305, thereby adapting to the spraying of pipes with different diameters, and being able to center the circular pipe so that the circular pipe is always located at the center of the spraying ring 101 to improve the uniformity of spraying.

[0040] As Figure 3 shown, a support frame 304 is provided at the end of the support rod 301, and the traveling wheel 305 is rotatably arranged in the support frame 304 along its axis. A connecting rod 303 is provided on the support frame 304, and the connecting rod 303 slides through the support rod 301 along its axis, and an elastic member 306 is provided between the support frame 304 and the end of the support rod 301.

[0041] When controlling the distance between multiple sets of traveling wheels 305, after the traveling wheels 305 come into contact with the outer wall of the circular pipe to be sprayed, the support rod 301 can be continuously controlled to slide to compress the elastic member 306, so as to apply pressure to the traveling wheels 305 through the elastic member 306, so that multiple sets of traveling wheels 305 can all stably contact the circular pipe, improving the stability of the device when moving along the axis of the circular pipe.

[0042] Specific usage method and beneficial effects of the present utility model:

[0043] When the spraying device is in use, it is sleeved on the circular pipe to be sprayed. One set of support rods 301 can be controlled to slide by rotating the threaded rod 401 to drive one set of traveling wheels 305 to move towards the direction close to the circular pipe. During the sliding process of one set of support rods 301, the driving disk 201 is driven to rotate through the cooperation between the linkage columns 302 and the guide grooves 202. During the rotation of the driving disk 201, the remaining sets of support rods 301 are driven to slide synchronously through the cooperation between the other sets of linkage columns 302 and the guide grooves 202 to quickly adjust the space enclosed by multiple sets of traveling wheels 305, which is convenient for spraying pipes with different diameters, and the adjustment is convenient and fast. During the adjustment process, the sliding distances of multiple sets of support rods 301 are the same, so that the circular pipe is always concentrically arranged with the spraying ring 101, and thus the spraying is more uniform.

[0044] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments. Based on the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
