[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] A spraying device for anti-corrosion and heat-insulating pipeline production, comprising an underground electromagnetic slide rail 1, characterized in that: a slider on the underground electromagnetic slide rail 1 is rotatably connected to a base unit 2, spraying arch frames 3 are set up on both sides of the underground electromagnetic slide rail 1, a pipeline inner support structure 4 is provided on the base unit 2, a paint storage barrel 5 is fixedly provided on the top of the spraying arch frame 3, an air pump 6 is fixedly provided on one side of the paint storage barrel 5 and located on the spraying arch frame 3, a spraying structure 7 is provided on the lower surface of the spraying arch frame 3, and a control console 8 is fixedly provided on one side of the spraying arch frame 3;

[0025] Two base units 2 form a group. One group of base units 2 shuttles through the spray arch frame 3 and is docked through a group of base units 2 to form a rotating roller. The insulation pipe is supported by the support structure 4 inside the pipeline and fixed on the rotating roller. Then one group of base units 2 shuttles under the spray arch frame 3, and the spray structure 7 starts to spray the outer surface of the insulation pipe. During the spraying process, the insulation pipe will rotate to make the paint evenly distributed on the outer surface of the insulation pipe.

[0026] The base unit 2 includes a base 21, a first rotating motor is arranged inside the base 21, an output end of the first rotating motor is fixedly connected to a rotating base 22, a hydraulic telescopic cylinder 23 is arranged inside the rotating base 22, an output end of the hydraulic telescopic cylinder 23 is fixedly connected to a docking base 24, a second rotating motor is arranged inside the docking base 24, an output end of the second rotating motor is fixedly connected to a first electric telescopic rod 25, an electromagnet 26 is fixedly arranged at the top of the first electric telescopic rod 25, a support structure 4 in the pipeline is fixedly connected to the middle section of the first electric telescopic rod 25, when installing the insulation pipe, the height of the docking base 24 can be changed by the hydraulic telescopic cylinder 23, without changing the height of the insulation pipe itself, and then the first extending end of the first electric telescopic rod 25 of a group of base units 2 is extended, so that the electromagnet 26 of a group of base units 2 is magnetically adsorbed to achieve fixation, at this time, the insulation pipe is sleeved with the first electric telescopic rod 25, after the support structure 4 in the pipeline completes the fixation of the inner wall of the insulation pipe, with the rotation of the second rotating motor, the first electric telescopic rod 25 is driven to rotate, so that the insulation pipe rotates at a uniform speed for spraying.

[0027] The supporting structure 4 in the pipeline includes a fixing ring 41, which is fixedly connected to the electric telescopic rod 25. The outer side of the fixing ring 41 is fixedly connected to the supporting ring 42 through a bracket. A second electric telescopic rod 43 is provided between the fixing ring 41 and the supporting ring 42. The control end of the second electric telescopic rod 43 is located inside the fixing ring 41. The initial section of the second electric telescopic rod 43 passes through the supporting ring 42. The output end of the second electric telescopic rod 43 is fixedly connected to the supporting block 44. After the first electric telescopic rod 25 is sleeved with the insulation pipe, the second electric telescopic rod 43 drives the supporting block 44 to move synchronously, so that the outer surface of the supporting block 44 contacts the inner wall of the insulation pipe, thereby fixing the inner wall of the insulation pipe, thereby driving the entire insulation pipe to rotate.

[0028] The spraying structure 7 includes a pipeline 71, on which a flow meter 72 is provided. The bottom of the pipeline 71 is threadedly connected to a spray template block 73. The spray template block 73 is fixedly connected to a nozzle 74 by bolts. The pipeline 71 is fixedly connected to a high-definition camera 75 by a bracket. The flow meter 72 can detect the flow rate of the internal paint and control the content of the paint. When spraying the outer surface of the insulation pipe, the high-definition camera 75 is used to collect data to determine the position and distance between the nozzle 74 and the outer surface of the insulation pipe. The thickness of the spray layer can also be observed through the data transmitted by the high-definition camera 75. Since the spray template block 73 is threadedly connected to the pipeline 71, spray template blocks 73 of different diameters can be selected according to the diameter of the insulation pipe to ensure that the spraying direction and distance of the nozzle 74 are always consistent with the outer surface of the insulation pipe, which is conducive to ensuring the consistency of the thickness of the spray layer.

[0029] An observation window is provided on the paint storage barrel 5, and a heating tube is provided inside the paint storage barrel 5. The output end of the paint storage barrel 5 is connected to the pipeline 71 through an electromagnetic valve. The spray template block 73 is a hollow structure. The air pump 6 is connected to one side of the spray template block 73 through a hose. The heating tube is used to insulate the paint inside the paint storage barrel 5 to prevent the paint from solidifying and being unable to flow. After the paint enters the spray template block 73, it is sprayed under the air pressure generated by the air pump 6 to ensure that each nozzle 74 is subjected to the same pressure.

[0030] A positioning sensor is fixedly arranged inside the electromagnet 26 , and the first electric telescopic rod 25 is a multi-stage telescopic rod, so that the supporting structure 4 in the pipeline will not be squeezed, thereby affecting the movement of the supporting structure 4 in the pipeline.

[0031] The buried electromagnetic slide rail 1, the first rotating motor, the hydraulic telescopic cylinder 23, the second rotating motor, the first electric telescopic rod 25, the electromagnet 26, the second electric telescopic rod 43, the nozzle 74 and the high-definition camera 75 are all electrically connected to the console 8. The entire device can be controlled by the console 8 to realize device automation and reduce manpower expenditure.

[0032] Working principle:

[0033] As shown in the figure, when in use, the insulated pipe to be sprayed is transported between a group of base units 2 by using the bracket, and the first electric telescopic rod 25 is controlled to move by the control console 8, so that the insulated pipe is sleeved on the first electric telescopic rod 25. As the first electric telescopic rod 25 contacts, the electromagnet 26 is energized to realize electromagnetic adsorption, and the first electric telescopic rods 25 are fixedly connected. After the connection is completed, the second electric telescopic rod 43 is synchronously moved by the control console 8, so that the support block 44 of the second electric telescopic rod 43 contacts the inner wall of the insulated pipe, and the insulated pipe is fixedly connected. Now fix the insulation pipe. After the fixation is completed, the bracket is withdrawn, and a group of base units 2 are synchronously controlled to move through the control console 8, driving one end of the insulation pipe to move to the bottom of the spray arch frame 3, and data is collected through the high-definition camera 75. The position and distance between the nozzle 74 and the outer surface of the insulation pipe are observed. The height of the nozzle 74 can be adjusted by the hydraulic telescopic cylinder 23, and the position of the nozzle 74 and the outer surface of the insulation pipe can be adjusted by the buried electromagnetic slide rail 1. After the position is completed, the spraying structure 7 is started, and the insulation pipe is sprayed with the nozzle 74.

[0034] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents.
