[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-4The deck machinery maintenance and rust removal device shown in the figure comprises a sand tank 6 and a sand outlet 3 arranged at the center of the bottom end of the sand tank 6, an air-controlled sand regulating valve 2 is arranged at the bottom end of the sand outlet 3, a sand pipe 12 is connected to the right end of the air-controlled sand regulating valve 2, a spray gun 10 is arranged at the top of the right end of the sand pipe 12, a placement support A1 is arranged at both corners of the bottom right end of the sand tank 6, a placement support B5 is arranged at both corners of the bottom left end of the sand tank 6, and moving wheels 4 are arranged on the outer walls of the two placement supports B5, a moving handle 8 is arranged at the left end of the top of the sand tank 6, an inspection port 7 is arranged at the center of the left end of the sand tank 6, and a sand adding port 9 is arranged at the center of the top of the sand tank 6, and the inspection port 7 and the sand adding port 9 are both fixed with sealed end covers by screws. When the deck machinery maintenance and rust removal device is used to remove rust on the deck by sandblasting, First, the deck machinery maintenance and rust removal device needs to be moved to the deck. When moving, it is necessary to hold the moving handle 8 and tilt the sand tank 6 so that the two placement pillars A1 at the bottom of the right end of the sand tank 6 are separated from the ground, and then the sand tank 6 is moved to the position where it needs to be used through the moving wheels 4 on the two placement pillars B5 at the bottom of the left end of the sand tank 6. Then, the sand tank 6 needs to be placed normally so that the bottom ends of the two placement pillars A1 are placed normally on the deck, so that the sand tank 6 can be placed firmly and stably, and then the deck machinery maintenance and rust removal device needs to be powered on through a long wire, and then the operator needs to hold the spray gun 10 and aim it at the position where rust needs to be removed, and then the deck machinery maintenance and rust removal device can be started normally to remove rust by sandblasting.

[0022] like Figure 1 and Figure 2 As shown, an air pipe is arranged at the front center of the sand tank 6, and a tee 16 is connected to the front end of the air pipe. A pressure gauge 17 is arranged at the top of the tee 16. The pressure gauge 17 can display the air pressure passing through the tee 16 in real time. The left end opening of the tee 16 is connected to a filter 15, and an inlet ball valve 14 is arranged at the left end of the filter 15. The bottom end opening of the tee 16 is connected to a sandblasting ball valve 18 through a pipeline. The bottom end of the sandblasting ball valve 18 is connected to a high-pressure air pipe 13, and the bottom end of the high-pressure air pipe 13 is connected to the air-controlled sand regulating valve 2. When the spray gun 10 is aimed at the position where sandblasting and rust removal are required, the sand tank 6 The internal high-pressure pump starts to work and absorbs external gas through the filter 15 on the three-way 16 and the inlet ball valve 14. After the external gas is filtered by the filter 15, it will be transported to the air-controlled sand regulating valve 2 through the sandblasting ball valve 18 at high pressure. At the same time, the rust-removing sand inside the sand tank 6 will enter the air-controlled sand regulating valve 2 through the sand outlet 3 at the bottom, and the high-pressure gas will drive the rust-removing sand to be transported to the sand pipe 12 at high pressure. Finally, the high-pressure gas will spray the rust-removing sand at the rust-removing location through the spray gun 10 at high pressure, so that the rust on the deck can be quickly removed.

[0023] like Figure 1 , Figure 3 and Figure 4As shown, an auxiliary sandblasting device 11 is arranged outside the center of the spray gun 10, and the auxiliary sandblasting device 11 includes a metal protective plate 19, a metal fixing sleeve 20, a roller 21 and a wheel groove 22. A metal fixing sleeve 20 is fixed at the center of the metal protective plate 19, and the metal fixing sleeve 20 is sleeved and fixed on the outside of the center of the spray gun 10. When the metal protective plate 19 is placed vertically, wheel grooves 22 are arranged on the left and right sides of the center of the bottom end, and rollers 21 are arranged inside the two wheel grooves 22. A wheel axle is arranged at the center of the roller 21, and the roller 21 is fixed in the wheel groove 22 through the wheel axle, and the bottom end and the front and rear ends of the roller 21 are respectively exposed outside the bottom end and the front and rear ends of the metal protective plate 19. The metal protective plate 19 and the metal fixing sleeve 20 are made of aluminum alloy. When the operator holds the spray gun 10 for a long time to remove rust on the deck, it will easily cause soreness and weakness of the arm muscles. Therefore, at this time, the operator can use the auxiliary sandblasting device 11 to operate the spray gun 1 more labor-saving 0 rust removal to relieve the soreness and weakness of the arm muscles. Specifically, it is necessary to align the bottom end of the metal protective plate 19 with the deck, and then place the metal protective plate 19 vertically or obliquely on the deck through the roller 21 inside the wheel groove 22. At this time, the roller 21 is directly placed on the deck, and then it only needs to be moved on the deck through the movement of the roller 21. In this way, the spray gun 10 will be moved synchronously, so that the spray gun 10 can remove rust on the deck through high-pressure sandblasting while moving, so as to achieve the purpose of saving effort. At the same time, when the rust-removing sand hits the deck with high pressure, a part of the rust-removing sand will rebound toward the operator due to the problem of the injection angle. If the high-pressure rebound rust-removing sand directly hits the operator, it will hurt the operator. However, because the metal protective plate 19 is fixed to the outside of the spray gun 10 through a metal fixing head, the high-pressure rebound rust-removing sand will hit the metal protective plate 19, thereby preventing the high-pressure rebound rust-removing sand from hitting the operator.
