The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figure 1 and Figure 2 As shown, a cleaning device for aluminum alloy shell production includes a winding device 1, a frame 2, a traveling frame 3, a docking frame 4 and a storage cylinder 5. The frame 2 is tilted and the tilt angle is 2°-5°. The docking frame 4 and the storage cylinder 5 are respectively installed on the front and rear ends of the frame 2. In the initial state, the traveling frame 3 is in the storage cylinder 5.

[0032] A water collecting tank 21 is provided at the rear end of the frame 2, and the storage tube 5 is connected to the water collecting tank 21, so that the water in the storage tube 5 flows into the water collecting tank 21. A plurality of tugboat groups for supporting the shell are installed on the frame 2, and the height of the tugboat groups gradually increases from the back to the front, so that the front end of the shell is higher than the rear end.

[0033] The winding device 1 includes a winding shaft, a belt drive mechanism and an integrated pipeline. The integrated pipeline is wound on the winding shaft. The belt drive mechanism drives the winding shaft to rotate so as to unwind and reel the integrated pipeline. The integrated pipeline is composed of a water pipe and a cable. One end of the water pipe is connected to a water pump. The water inlet end of the water pump is connected to the water collecting tank 21. One end of the cable is conductively connected to the power supply device and the control device, and the other end of the cable and the water pipe is connected to the walking frame 3.

[0034] The storage cylinder 5 includes a fixed cylinder 51, a rotating ring 52 and a gear driving mechanism 53. The fixed cylinder 51 is fixedly installed at the rear end of the frame 2. A water outlet is provided at the bottom of the rear end of the fixed cylinder 51 and a connecting pipe is installed between the water collecting tank 21. The rotating ring 52 is coaxially installed at the front end of the fixed cylinder 51, and the gear driving mechanism 53 is used to drive the rotating ring 52 to rotate.

[0035] like Figure 5 and Figure 6As shown, the traveling frame 3 includes a front axle 31, a rear axle 32, a winding device 33, a wiper assembly 34, a water squeezing assembly 35 and a guide groove 36. The front axle 31 and the rear axle 32 are coaxially connected for rotation. A motor 1 is installed on the rear axle 32. The output end of the motor 1 is fixedly connected to the front axle 31, so as to drive the front axle 31 to rotate relative to the rear axle 32.

[0036] The front axle 31 and the rear axle 32 are respectively mounted with a front supporting wheel group 311 and a rear supporting wheel group 321, wherein the front supporting wheel group 311 and the rear supporting wheel group 321 have at least three supporting wheels, and the supporting wheels are connected to the front axle 31 / rear axle 32 through a mounting rod, and the connection between the mounting rod and the front axle 31 / rear axle 32 is elastically hinged, so that the mounting rod can swing within a small angle (preferably, the mounting rod can swing within a range of 1°-2°), so that the supporting wheels can be pressed against the inner wall of the shell, and the supporting wheels can be supported. The wheels are in contact with the inner wall of the shell, and the three support wheels are arranged in a circular array. The front support wheels in the front support wheel group 311 are tilted, so that the axis of the front support wheels forms an acute angle with the axis of the front axle 31, and the axis of the rear support wheels in the rear support wheel group 321 is perpendicular to the axis of the rear axle 32, so that the front axle 31 rotates relative to the rear axle 32. The clockwise / counterclockwise rotation of the front support wheel group 311 causes the front axle 31 to be subjected to a forward / backward force, so that the front axle 31 and the rear axle 32 move forward / backward;

[0037] A nozzle 312 is installed on the front end side of the front axle 31, and a water pipe is connected to the rear end of the rear axle 32. Channels connected to the nozzle 312 and the water pipe are respectively provided in the front axle 31 and the rear axle 32, and a rotating joint 313 connecting the two channels is installed between the front axle 31 and the rear axle 32, so that cleaning liquid is supplied through the water pipe, and the cleaning liquid is finally sprayed out from the nozzle 312 to clean the inner wall of the shell.

[0038] like Figure 3 and Figure 5 As shown, the winding device 33 includes a winding roller 331, a sponge belt 332 and a second motor 333. The winding roller 331 is rotatably installed below the rear shaft 32, and the two are perpendicular to each other. The second motor 333 is installed on the rear shaft 32. A sprocket chain transmission mechanism is installed between the output end of the second motor 333 and the winding roller 331 to drive the winding roller 331 to rotate. The sponge belt 332 is wound around the winding roller 331. A waterproof layer is provided on the upper surface of the sponge belt 332. The other end of the sponge belt 332 is connected to the rotating ring 52.

[0039] Two guide wheels 322 are installed on the rear axle 32, and the guide wheels 322 abut against the upper surface of the sponge belt 332, so that the middle of the sponge belt 332 is depressed downward to form a water guide groove, and the cleaning liquid is guided from the front end of the sponge belt 332 to the storage tube 5;

[0040] The water squeezing assembly 35 includes a spring telescopic rod 351, a connecting frame 352, two conical pressure rollers 353 and a squeezing roller 354. The front sides of the conical pressure roller 353 and the squeezing roller 354 are flush and against the sponge belt 332. The conical pressure roller 353 and the squeezing roller 354 are rotatably installed on the connecting frame 352 and are located at the same height as the winding roller 331. The spring telescopic rod 351 is installed on the rear axle 32. The telescopic end of the spring telescopic rod 351 is connected to the connecting frame 352. The conical pressure roller 353 and the squeezing roller 354 squeeze the sponge belt 332 to squeeze out the water on the sponge belt 332. Since the ends of the two conical pressure rollers 353 that are away from each other are higher, the water flows along the conical pressure roller 353 toward the squeezing roller 354 and finally flows into the water guide groove.

[0041] like Figure 3 , Figure 5 and Figure 6 As shown, the wiper assembly 34 includes a wiper blade 341 and a connecting rod 342. The two ends of the connecting rod 342 are connected to the wiper blade 341 and the front shaft 31 respectively. The wiper blade 341 is composed of a front section and a rear section. The outer side of the front section is in contact with the inner wall of the shell, and a water retaining edge is provided on the inner side. The rear section is tubular and connected to the front section. When the front shaft 31 rotates, the front section of the wiper blade 341 scrapes the cleaning liquid on the inner wall of the shell into the rear section of the wiper blade 341. When the inner side of the rear section is downward, the cleaning liquid stored in the rear section is poured into the guide groove 36.

[0042] The guide groove 36 is fixedly mounted on the rear axle 32, and the front end of the guide groove 36 extends to the rear end of the wiper blade 341, so as to receive the cleaning fluid flowing out from the rear end of the wiper blade 341. The guide groove 36 is provided with a guide channel inclined rearward and downward, so that the cleaning fluid flows through the guide channel into the water guide groove formed by the sponge belt 332.

[0043] like Figure 4 , Figure 5 and Figure 7 As shown, the docking frame 4 includes a sliding seat 41, a clamping claw 42 and a fork rod 43. The sliding seat 41 is installed on the frame 2 and can move along the front and rear directions of the frame 2. The clamping claw 42 and the fork rod 43 are installed on the top of the sliding seat 41. The front end of the front axle 31 is provided with a matching ring that is compatible with the clamping claw 42. When the walking frame 3 moves to the front end of the shell, the sliding seat 41 approaches the walking frame 3 so that the fork rod 43 is inserted between the front supporting wheel group 311. At the same time, the clamping claw 42 clamps the docking ring, and then the sliding seat 41 moves forward to move the walking frame 3 out of the shell.

[0044] Working principle: the shell is transported to the frame 2 by a hoisting crane, and the front axle 31 rotates when the motor is started, so that the walking frame 3 moves forward into the shell. At the same time, the motor 2 333 rotates to make the winding roller 331 rotate to unwind the sponge belt 332, and the sponge belt 332 passes through the guide wheel 322 to form a water guide groove. At the same time, the nozzle 312 sprays cold water to clean the inner wall for the first time, and the front section of the wiper plate 341 scrapes the cleaning liquid on the inner wall of the shell into the rear section of the wiper plate 341. When the inner side of the rear section is downward, the cleaning liquid accumulated in the rear section is poured into the guide groove 36, so that the cleaning liquid flows through the guide channel to the water guide groove formed by the sponge belt 332, and flows to the rear end of the storage tube 5 through the water guide groove and enters the water collecting tank 21, so as to prevent impurities from flowing down along the inner wall of the shell and gathering at the inner bottom of the shell. When the walking frame 3 moves to the front end of the shell, the nozzle 312 sprays hot water mixed with the cleaning agent. The frame 3 moves to the rear end and reels the sponge belt 332. After the excess hot water flows onto the sponge belt 332, the sponge belt 332 is reeled up and the water squeezing assembly 35 squeezes the sponge so that the water absorbed on the sponge flows to the top surface of the sponge and enters the sump 21. After the walking frame 3 moves to the rear end of the shell, the walking frame 3 moves forward again, and the nozzle 312 sprays cold water to clean the inner wall of the shell. Finally, the walking frame 3 moves to the front end of the shell again, and the sliding seat 41 approaches the walking frame 3 so that the fork rod 43 is inserted between the front supporting wheel group 311, and the clamping claw 42 clamps the docking ring. Then the sliding seat 41 moves forward to move the walking frame 3 out of the shell. When the motor is started, the rear axle 32 rotates, and the rotating ring 52 rotates, so that the sponge belt 332 absorbs water and wipes the inner wall of the shell. Finally, the walking frame 3 is put back into the shell, the walking frame 3 is reset, and the shell cleaning is completed.

[0045] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
