Description

Technical Field

[0001] The utility model relates to the technical field of round pipe spraying, and particularly relates to an automatic spraying device for a round pipe with an opening and closing function. Background Technique

[0002] To prevent the round pipe from rusting and corroding, it is necessary to spray the outer surface of the metal round pipe exposed to the air. Spraying can form a protective film on the outer surface of the round pipe, effectively isolating the round pipe from the external corrosive environment, thus significantly extending the service life of the round pipe and reducing the maintenance and replacement costs caused by corrosion. Especially in harsh environments such as humidity and salt spray, the sprayed round pipe can better resist corrosion and maintain the integrity of its structure and function. At the same time, it can also provide a variety of color and texture options for the round pipe, making the appearance of the round pipe more vivid and uniform, meeting different design requirements, enhancing the overall visual effect of the round pipe, and increasing the aesthetic degree.

[0003] For example, the Chinese utility model patent with the patent number 202322122713.2 provides a spraying ring for the outer wall of a pipeline, which facilitates the spraying body to rotate cyclically when spraying the outer wall of the pipeline by the spraying ring main body, greatly improving the uniformity of spraying on the outer wall of the pipeline. This method is simple to operate and does not require the rotating motor to flip back and forth for work.

[0004] However, most of the existing round pipe spraying devices can only spray the uninstalled round pipes, and it is not convenient to spray the installed round pipes, resulting in a reduction in their applicable range. Therefore, in view of this, an automatic spraying device for a round pipe with an opening and closing function is proposed to solve the above technical problems. Content of the Utility Model

[0038] The present utility model will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present utility model and cannot be construed as limiting the protection scope of the present utility model. Those skilled in the art can make some non-essential improvements and adjustments to the present utility model based on the above application content.

[0039] Embodiment:

[0040] As Figure 1 、 2 shown, the present utility model provides an automatic spraying device for a round tube with an opening and closing function, including a mounting frame 301. Two sets of spray shells 101 arranged oppositely are hinged on the mounting frame 301. The two sets of spray shells 101 are connected to an external feeding device through a feeding pipe 102, and multiple sets of nozzles 105 are arranged on the spray shells 101.

[0041] During use, after the two sets of spray shells 101 in the open state are sleeved on the round tube to be sprayed, the two sets of spray shells 101 are controlled to close, and the whole spraying device is moved along the round tube. The coating is input into the spray shells 101 through an external feeding device and sprayed out through the nozzles 105 to fully spray the outer surface of the round tube.

[0042] As Figures 1 to 4 shown, in this embodiment, multiple sets of mounting rods 401 are slidably arranged on the spray shell 101 along its diameter line. A traveling component is arranged at the end of the mounting rod 401. An opening and closing mechanism connected to the two sets of spray shells 101 is arranged on the mounting frame 301. The two sets of spray shells 101 are driven to rotate along their hinge points with the mounting frame 301 through the opening and closing mechanism, and multiple sets of nozzles 105 are driven to slide simultaneously after the two sets of spray shells 101 are closed.

[0043] The opening and closing mechanism includes two sets of sector rings 201. The two sets of sector rings 201 are respectively rotatably arranged in the two sets of spray shells 101. An inclined groove 202 is opened on the sector ring 201. An elastic propulsion component connected to the spray shell 101 is arranged on the sector ring 201. When the sector ring 201 opens and closes, the spray shell 101 is pushed to open and close through the elastic propulsion component. The elastic propulsion component includes a cover body 103 arranged on the spray shell 101. A first baffle 104 is arranged on the cover body 103. A second baffle 203 is arranged on the sector ring 201. A first elastic member 204 is arranged between the second baffle 203 and the first baffle 104.

[0044] The mounting bracket 301 is also provided with a control component connected to the two sets of sector rings 201. The control component drives the two sets of sector rings 201 to open and close, and drives the two sets of sector rings 201 to rotate after the spraying shell 101 is closed. A driving column 402 is arranged on the mounting rod 401, and the driving column 402 is slidably clamped in the inclined groove 202. The control component includes a threaded rod 302 screwed on the mounting bracket 301. A connecting seat 303 is rotatably connected to the end of the threaded rod 302. The control component also includes two connecting rods 304. One end of each connecting rod 304 is hinged to the connecting seat 303, and the other end is hinged to the sector ring 201.

[0045] In the initial state, the two spraying shells 101 are in an open state. By rotating the threaded rod 302, it can slide on the mounting bracket 301 to drive the connecting seat 303 to move towards the inside of the mounting bracket 301. When the spraying shell 101 is opened, under the action of the first elastic member 204, the sector ring 201 can push the spraying shell 101 to move synchronously during the movement. The sector ring 201 and the spraying shell 101 are in an integrated state. Then, under the movement of the connecting seat 303, the two spraying shells 101 are driven to rotate and close through the connecting rods 304.

[0046] After the spraying of the two spraying shells 101 is completed, continue to rotate the threaded rod 302 to drive the connecting seat 303 to continue moving. At this time, the spraying shell 101 cannot move. During the movement of the connecting seat 303, the two ends of the two sets of sector rings 201 can be pulled together through the connecting rods 304, so that the two sets of sector rings 201 rotate on the two sets of spraying shells 101 respectively. During the rotation of the sector ring 201, the multi-group mounting rods 401 can be driven to slide along their axes through the cooperation of the inclined groove 202 and the driving column 402, so that the multi-group traveling components move simultaneously until the traveling components contact the outer wall of the circular tube.

[0047] As Figure 4 shown, in this embodiment, the traveling component includes a telescopic rod 403 slidably penetrating through the mounting rod 401. An installation seat 405 is arranged at the end of the telescopic rod 403. A second elastic member 404 is arranged between the installation seat 405 and the mounting rod 401. A traveling wheel 406 is rotatably arranged on the installation seat 405. A driving motor 407 for driving the traveling wheel 406 to rotate is arranged on the installation seat 405.

[0048] When the traveling wheel 406 in the traveling component contacts the circular tube, the driving motor 407 can be used to drive the traveling wheel 406 to rotate, so as to control the entire spraying device to move along the axis of the circular tube, and then realize the automatic spraying of the circular tube. Through the arrangement of the second elastic member 404, the friction between the traveling wheel 406 and the circular tube can be increased, so that the device can walk stably along the circular tube.

[0049] The specific usage method and beneficial effects of the present utility model:

[0050] When the device is in use, two sets of spraying shells 101 in the open state can be sleeved on the pipeline to be sprayed. Then, the opening and closing mechanism is used to control the two sets of spraying shells 101 to close. After the two sets of spraying shells 101 are closed, a plurality of mounting rods 401 can be driven to close along their axes at the same time, so that a plurality of walking components are in contact with the pipeline to be sprayed. Then, the whole spraying device can be driven to move along the pipeline by the walking components, driving a plurality of nozzles 105 to move along the pipeline. The spraying shell 101 is fed by an external feeding device, and the coating is sprayed through the nozzles 105 to spray the outer surface of the circular pipe. With this spraying device, the pipeline that has not been installed can be automatically sprayed, and the installed pipeline can also be sprayed, effectively improving the applicable range of the spraying device.

[0051] The foregoing has shown and described the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments. Based on the present invention, 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 invention all fall within the scope of protection required by the present invention.
