[0031] Please refer to Figure 1 The ship body sand blasting device 10 provided by the embodiment of the present application is used to spray sand on the outer surface of the ship body 1 without the need for the operator to hold the sand blasting gun 600, thereby saving time and effort and improving work efficiency.

[0032] Please refer to Figure 1 And Figure 2 In the embodiment of the present application, the ship body sand blasting device 10 comprises a sliding rail assembly 100, a pulley assembly 200, a fixing assembly 300, an adjusting assembly 400, a mounting assembly 500 and a sand blasting gun 600. The sliding rail assembly 100 is used to be detachably connected with the outer surface of the ship body 1, the sliding rail assembly 100 is arranged along the length direction of the ship body 1, and the pulley assembly 200 is in sliding fit with the sliding rail assembly 100. The fixing assembly 300 is connected with the pulley assembly 200, the adjusting assembly 400 is mounted on the fixing assembly 300 and can move along the height direction of the ship body 1 relative to the fixing assembly 300. The mounting assembly 500 is connected with the adjusting assembly 400, the sand blasting gun 600 is mounted on the mounting assembly 500, and the sand blasting gun 600 is used to spray sand on the outer surface of the ship body 1.

[0033] Since the sand blasting gun 600 is installed on the mounting assembly 500, it is not necessary for the operator to shoulder and hold it manually. Since the slide rail assembly 100 is used to detachably connect with the outer surface of the ship body 1, when the outer surface of the ship body 1 needs to be sand blasted, the slide rail assembly 100 is first connected with the outer surface of the ship body 1. Since the slide rail assembly 100 is arranged along the length direction of the ship body 1, the pulley assembly 200 is in sliding fit with the slide rail assembly 100, so that the pulley assembly 200 is slid relative to the slide rail assembly 100 to drive the sand blasting gun 600 to move along the length direction of the ship body 1. Since the adjusting assembly 400 can move relative to the fixing assembly 300 along the height direction of the ship body 1, the adjusting assembly 400 can drive the sand blasting gun 600 to move along the height direction of the ship body 1.

[0034] Next, the method for sand blasting the ship body 1 by the ship body sand blasting device 10 provided by the embodiment of the present application is described:

[0035] 1) The slide rail assembly 100 is connected with the outer surface of the ship body 1, and the sand blasting gun 600 is installed on the mounting assembly 500, so that the nozzle of the sand blasting gun 600 is aligned with the outer surface of the ship body 1;

[0036] 2) The pulley assembly 200 is moved in the slide rail assembly 100 to drive the sand blasting gun 600 to move along the length direction of the ship body 1, so that the sand blasting gun 600 performs sand blasting within a certain length of the ship body 1 to form a first sand blasted layer;

[0037] 3) The adjusting assembly 400 is moved in the fixing assembly 300 to drive the sand blasting gun 600 to move along the height direction of the ship body 1 to above or below the first sand blasted layer, and then the pulley assembly 200 is moved in the slide rail assembly 100 again, so that the sand blasting gun 600 forms a second sand blasted layer on the outer surface of the ship body 1;

[0038] 4) Step 3) is repeated until the height of the adjusting assembly 400 cannot be adjusted any more, then the slide rail assembly 100 is detached from the outer surface of the ship body 1 and connected to the next area that needs to be sand blasted, until the sand blasting is completed.

[0039] As can be seen from the above, during the entire sand blasting process, the operator only needs to move the pulley assembly 200 and the adjusting assembly 400, and periodically move the position of the sand blasting device, so as to complete the sand blasting of the outer surface of the ship body 1, without the operator manually holding the sand blasting gun 600 to sand blast on the outer surface of the ship body 1 in a large range. That is, the operator does not need to shoulder and hold the sand blasting gun 600 during the entire sand blasting process, so as to save time and effort and improve work efficiency.

[0040] It should be noted that the above steps are to sand blast row by row along the height direction of the ship body 1, of course, it can also be to sand blast column by column along the length direction of the ship body 1, which is not limited.

[0041] See also Figures 2-5 In some embodiments, the fixing assembly 300 includes a fixing sleeve 310, a fixing member 320 and a driving member 330. The fixing sleeve 310 is connected to the pulley assembly 200. The fixing member 320 is movably arranged in the fixing sleeve 310. The driving member 330 is transmission-connected to the fixing member 320. The fixing member 320 has a first fixing hole 321, and the fixing sleeve 310 has a second fixing hole 311. The adjustment assembly 400 is movably passed through the first fixing hole 321 and the second fixing hole 311; wherein the driving member 330 can drive the fixing member 320 to move relative to the fixing sleeve 310 so that the adjustment assembly 400 is fixed in the fixing sleeve 310.

[0042] The fixing assembly 300 can be arranged along the length direction of the hull 1, and the adjusting assembly 400 can be arranged along the height direction of the hull 1, so as to facilitate the adjustment assembly 400 to be installed on the fixing assembly 300 and move relative to the fixing assembly 300 along the height direction of the hull 1.

[0043] Because the adjustment assembly 400 is movably inserted through the first fixing hole 321 and the second fixing hole 311, the adjustment assembly 400 can move up and down in the first fixing hole 321 and the second fixing hole 311 to achieve movement along the height direction of the hull 1 relative to the fixing assembly 300. After the height of the adjustment assembly 400 is adjusted, the driving member 330 drives the fixing member 320 to move relative to the fixing sleeve 310, so that the adjustment assembly 400 is fixed within the fixing sleeve 310. Because the adjustment assembly 400 is inserted through both the first fixing hole 321 and the second fixing hole 311, when the driving member 330 drives the fixing member 320 to move relative to the fixing sleeve 310, the fixing sleeve 310 exerts a force in the opposite direction on the adjustment assembly 400, thereby keeping the adjustment assembly 400 stationary.

[0044] by Figure 2 Taking the orientation in as an example, when the driving member 330 drives the fixing member 320 to move to the left relative to the fixing sleeve 310, the adjustment component 400 will tend to move to the left, and the hole wall on the left side of the second fixing hole 311 will apply rightward pressure to the adjustment component 400. The greater the pressure, the greater the friction between the adjustment component 400 and the hole wall on the left side of the second fixing hole 311, so that the adjustment component 400 is fixed to the fixing component 300 under the action of friction.

[0045] Specifically, the fixing member 320 may be a fixed screw, and the driving member 330 may be a fixed nut. One end of the fixing member 320 extends out of the fixing sleeve 310, and the driving member 330 is screwed to the end of the fixing member 320 that extends out of the fixing sleeve 310. In this way, when the driving member 330 is turned, the fixing member 320 will move relative to the fixing sleeve 310 under the action of the thread transmission.

[0046] See also Figure 2 and Figure 3 In some embodiments, the adjustment assembly 400 includes an adjustment rod 410, a mounting member 420 and a rotating member 430. The adjustment rod 410 is movably inserted into the first fixing hole 321 and the second fixing hole 311. The mounting member 420 is connected to the adjustment rod 410. The rotating member 430 is rotatably set in the mounting member 420. The installation assembly 500 is connected to the rotating member 430.

[0047] Specifically, when the adjustment rod 410 moves along the height of the hull 1 within the fixed assembly 300, it sequentially drives the sandblasting gun 600 up and down through the mounting member 420, the rotating member 430, and the mounting assembly 500. Because the rotating member 430 is rotatably mounted within the mounting member 420 and the mounting assembly 500 is connected to the rotating member 430, the rotating member 430 can rotate relative to the mounting member 420, thereby driving the sandblasting gun 600 through a certain angle via the mounting assembly 500. This means that the sandblasting gun 600 can not only move along the length and height of the hull 1 to cover a certain range, but also adjust its angle to enhance sandblasting accuracy.

[0048] It should be noted that, in order to prevent the mounting assembly 500 and the sandblasting gun 600 from interfering with the slide rail assembly 100, the mounting member 420 is disposed on the side of the adjustment rod 410 away from the slide rail assembly 100, thereby allowing both the mounting assembly 500 and the sandblasting gun 600 to be disposed away from the slide rail assembly 100. Specifically, the slide rail assembly 100 is located above the adjustment assembly 400, and the mounting member 420 is disposed below the adjustment rod 410.

[0049] See also Figure 2 and Figure 3 In some embodiments, the rotating member 430 includes a spherical portion 431 and a connecting portion 432 . The spherical portion 431 is movably mounted in the mounting member 420 , and the connecting portion 432 is connected to the mounting assembly 500 .

[0050] The spherical portion 431 is spherical and is movably installed in the mounting member 420, that is, the spherical portion 431 can rotate 360° in all directions, thereby driving the sandblasting gun 600 to rotate in a large range through the connecting portion 432, so that the sandblasting gun 600 can be rotated at any angle as needed, further improving the convenience of sandblasting.

[0051] See also Figure 2 and Figure 3 In some embodiments, the mounting member 420 includes a mounting plate 421 and a mounting portion 422. The mounting plate 421 is connected to the adjustment rod 410, and the mounting plate 421 is arranged at an angle to the adjustment rod 410. The mounting portion 422 is arranged on a side of the mounting plate 421 away from the adjustment rod 410, and the rotating member 430 is rotatably arranged in the mounting portion 422.

[0052] Since the adjusting rod 410 is arranged along the height direction of the ship body 1, the mounting plate 421 can be arranged vertically with the adjusting rod 410, so that the side of the mounting plate 421 away from the adjusting rod 410 has a certain area, which can provide a mounting basis for the mounting portion 422. It can be understood that the spherical portion 431 is movably mounted in the mounting portion 422, so the mounting portion 422 needs to have a certain thickness, which can be a block structure. The mounting portion 422 is provided with a mounting cavity, and the rotating member 430 is mounted in the mounting cavity.

[0053] Of course, since the mounting member 420 needs to bear the weight of the mounting assembly 500, in order to strengthen the connection strength between the mounting member 420 and the adjusting rod 410, the mounting member 420 further includes a reinforcing plate 423, which is arranged between the adjusting rod 410 and the mounting plate 421, so that the mounting plate 421 can be more stable on the adjusting rod 410 and is not easy to fall off.

[0054] Please refer to Figure 2 In some embodiments, the adjusting assembly 400 further includes a first limiting member 424, which is arranged at the end of the adjusting rod 410 away from the mounting member 420.

[0055] Since the adjusting rod 410 is movably arranged in the first fixed hole 321 and the second fixed hole 311, and the mounting member 420 is arranged below the adjusting rod 410, in order to avoid the adjusting rod 410 from sliding out of the first fixed hole 321 and the second fixed hole 311 under the action of its own gravity when adjusting the height of the adjusting rod 410, the first limiting member 424 is arranged at the end of the adjusting rod 410 away from the mounting member 420. The size of the first limiting member 424 is larger than the size of the first fixed hole 321 and the second fixed hole 311, so that under the limiting action of the first limiting member 424, the adjusting rod 410 can be prevented from sliding out of the first fixed hole 321 and the second fixed hole 311.

[0056] Please refer to Figure 2 In some embodiments, the mounting assembly 500 includes a fastener 510 and a mounting ring 520, the mounting ring 520 is connected with the adjusting assembly 400, the sand blasting gun 600 is mounted in the mounting ring 520, and the fastener 510 is arranged on the mounting ring 520 and abuts against the sand blasting gun 600.

[0057] Since the sand blasting gun 600 is installed in the mounting ring 520, the fastener 510 is arranged on the mounting ring 520 and abuts against the sand blasting gun 600, so that the sand blasting gun 600 can be fixed in the mounting ring 520 to avoid the sand blasting gun 600 from falling out of the mounting ring 520 as much as possible. Specifically, the fastener 510 can be a fastening bolt, and a plurality of fasteners 510 can be arranged on the mounting ring 520 at intervals, so that the sand blasting gun 600 can be abutted from multiple directions, thereby further enhancing the fixing effect of the sand blasting gun 600.

[0058] Specifically, the mounting assembly 500 is hinged to the adjusting assembly 400. That is, the mounting assembly 500 and the adjusting assembly 400 are connected by a hinge shaft, and the mounting assembly 500 can rotate around the hinge shaft relative to the adjusting assembly 400, so that the angle of the sand blasting gun 600 can be further adjusted, thereby making the angle adjustment of the sand blasting gun 600 more accurate and the spray angle of the sand blasting gun 600 more accurate.

[0059] Please refer to Figure 2 and Figure 3 In some embodiments, the slide rail assembly 100 includes a slide rail body 110 and two second limiters 120 arranged at two ends of the slide rail body 110, and the pulley assembly 200 is in sliding fit with the slide rail body 110.

[0060] That is, the slide rail body 110 is arranged along the length direction of the ship body 1, the pulley assembly 200 is in sliding fit with the slide rail body 110 and can move along the length direction of the ship body 1. Since the two second limiters 120 are arranged at two ends of the slide rail body 110, the pulley assembly 200 can be prevented from falling off the slide rail body 110 to a certain extent when moving in the slide rail body 110 under the limiting action of the two second limiters 120.

[0061] The pulley assembly 200 can include a pulley body 210 and a connecting rod 220, the pulley body 210 is in sliding fit with the slide rail body 110, and the connecting rod 220 is connected to the fixing assembly 300.

[0062] Specifically, the slide rail assembly 100 further includes a plurality of assembly plates 130, the slide rail body 110 includes a slide rail part 111 and a plurality of welding parts 112, the plurality of welding parts 112 are arranged one by one corresponding to the plurality of assembly plates 130, the plurality of welding parts 112 are arranged at intervals in the slide rail part 111, and the slide rail part 111 is located in the welding part 112, the welding part 112 is welded to the corresponding assembly plate 130, and the assembly plate 130 is detachably connected to the outer surface of the ship body 1 through a connecting piece 131, so as to realize the detachable installation of the slide rail assembly 100 on the outer surface of the ship body 1. The connecting piece 131 can be a connecting bolt.
