[0002] Since the pipelines used in ships often come into contact with water, in order to ensure good cleanliness and roughness of the inner and outer walls of the pipelines and the steel structures, it is necessary to perform pre-treatment such as rust removal on the surfaces of the inner and outer walls of the pipeline steel structures. In the existing rust removal work for the inner walls of ship pipelines, it is necessary to grind the rust on the inner walls of the pipelines before applying anti-rust paint and the like.

[0003] However, since the diameter of the pipelines used in ships is small, it is not easy for workers to enter the pipelines to grind and remove rust on the inner walls of the pipelines. Moreover, due to the long length of the pipelines, it is also impossible to use an extended support rod to connect the grinding device and extend it into the pipelines to grind the inner walls of the pipelines, and it is not easy to grind the iron filings in the pipelines easily and efficiently. In view of this, a pipeline rust removal device for shipbuilding is proposed to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1-2 and Figure 4 , a pipe rust removal device for shipbuilding in this embodiment includes a pipe body 1, a positioning mechanism 2 is arranged inside the pipe body 1, an adjusting mechanism 3 is arranged on the positioning mechanism 2, and a grinding assembly 4 is arranged on the adjusting mechanism 3.

[0023] The adjusting mechanism 3 includes an air storage tank 306, a protection box 314 and an air pump 301. An air storage tank 306 is arranged inside the pipe body 1. A piston cylinder 313 is communicated with the air storage tank 306. A piston plate 307 is slidably and tightly fitted inside the piston cylinder 313. One end of the piston plate 307 is fixed with a piston rod 308.

[0024] A protection box 314 is arranged on the positioning mechanism 2. A rotatable rotating shaft 304 is horizontally arranged inside the protection box 314. One end of the rotating shaft 304 is fixed to the air storage tank 306. The rotating shaft 304 is hollow. A rotary joint 312 is rotatably installed at one end of the rotating shaft 304. A gas transmission pipe 302 is communicated with one side of the rotary joint 312. One end of the gas transmission pipe 302 is communicated with an air pump 301. One side of the air pump 301 is fixed to a fixed box 201.

[0025] The grinding assembly 4 includes a second support 403. One side of the piston rod 308 close to the inner peripheral wall of the pipe body 1 is fixed with a second support 403. A grinding roller 402 for grinding the inner peripheral wall of the pipe body 1 is rotatably installed inside the second support 403. A third motor 401 for driving the grinding roller 402 to rotate is fixed on the second support 403.

[0026] By starting the air pump 301, the air pump 301 conveys gas into the gas transmission pipe 302. Subsequently, the gas is conveyed into the rotary joint 312 and the rotating shaft 304 until it flows into the air storage tank 306 and then is conveyed into the piston cylinder 313. At this time, the gas pushes the piston rod 308 on the piston plate 307 to move, so that the grinding roller 402 on the second support 403 contacts the inner peripheral wall of the pipe body 1, thus facilitating subsequent grinding.

[0027] Among them, there are four groups of piston cylinders 313, which are equidistantly arranged on the air storage tank 306. The grinding rollers 402 on the multiple groups of piston cylinders 313 are convenient for quickly grinding the inside of the pipe body 1.

[0028] Meanwhile, a pressure sensor 305 for monitoring the air pressure of the air storage tank 306 is provided on the air storage tank 306. One side of the air delivery pipe 302 is communicated with an air discharge pipe 303. Solenoid valves are fixed on both the air discharge pipe 303 and the air delivery pipe 302 to control the outflow of gas, facilitating the monitoring of the air pressure in the air storage tank 306, so that the gas in the air storage tank 306 can ensure that the grinding roller 402 always fits the inner peripheral wall of the pipe body 1.

[0029] In addition, a driven bevel gear 311 is fixed on the rotating shaft 304. A second motor 309 is provided on the positioning mechanism 2. The output end of the second motor 309 is fixed with a driving bevel gear 310 meshing with the driven bevel gear 311. The driven bevel gear 311, the rotary joint 312, the second motor 309 and the driving bevel gear 310 are all located in the protection box 314. The second motor 309 is fixedly installed in the protection box 314. By starting the second motor 309, the second motor 309 drives the driving bevel gear 310 to rotate, and then the driving bevel gear 310 meshes with the driven bevel gear 311, so that the rotating shaft 304 can rotate, and then drives the air storage tank 306 to rotate, enabling the grinding roller 402 on its upper part to evenly grind the inner peripheral wall of the pipe body 1.

[0030] Please refer to Figure 1-3 , the positioning mechanism 2 in this embodiment includes a fixed box 201. The fixed box 201 is arranged inside the pipe body 1. A plurality of cylinders 202 distributed at equal intervals are fixed inside the fixed box 201. The output end of the cylinder 202 is fixed with a first bracket 203. A wheel 205 is rotatably installed inside the first bracket 203. One side of the wheel 205 is in sliding contact with the inner wall of the pipe body 1. A first motor 204 for driving the wheel 205 to rotate is fixed on the first bracket 203. One side of the fixed box 201 is fixed to the protection box.

[0031] By starting the cylinder 202, the cylinder 202 drives the first bracket 203 to move, so that the wheel 205 on the first bracket 203 abuts against the inner peripheral wall of the pipe body 1. Then, by starting the first motor 204 to drive the wheel 205 to rotate, the fixed box 201 can be driven to move.

[0032] It should be noted that on multiple groups of brackets, usually only one group of brackets is provided with the first motor 204. By starting the first motor 204 to drive the wheel 205 to rotate, the fixed box 201 can be driven to move freely, while the other wheels 205 play a supporting role for the fixed box 201.

[0033] The working principle of the above embodiment is as follows:

[0034] First, place the fixed box 201 inside the pipe body 1. Then, start the cylinder 202 to drive the first bracket 203 to move, so that the wheels 205 on the first bracket 203 abut against the inner peripheral wall of the pipe body 1. Next, start the first motor 204 to drive the wheels 205 to rotate, thereby driving the fixed box 201 to move inside the pipe body 1.

[0035] At this time, start the air pump 301. The air pump 301 transports the gas into the air delivery pipe 302. Subsequently, the gas is transported into the rotary joint 312 and the rotating shaft 304 until it flows into the air storage box 306, and then is transported into the piston cylinder 313. At this time, the gas pushes the piston rod 308 on the piston plate 307 to move, so that the grinding roller 402 on the second bracket 403 contacts the inner peripheral wall of the pipe body 1. At this time, the air pressure sensor 305 can be used to monitor the air pressure in the air storage box 306, so that the gas in the air storage box 306 can ensure that the grinding roller 402 can always fit against the inner peripheral wall of the pipe body 1.

[0036] Then, start the third motor 401 and the second motor 309. The third motor 401 drives the grinding roller 402 to rotate. Start the second motor 309. The second motor 309 drives the driving bevel gear 310 to rotate. Then, the driving bevel gear 310 meshes with the driven bevel gear 311, so that the rotating shaft 304 can rotate. Subsequently, the air storage box 306 is driven to rotate, so that the grinding roller 402 on its upper part can evenly grind the inner peripheral wall of the pipe body 1.
