[0040] See also Figure 1 、 Figure 2 and Figure 3 The embodiment of the present invention is a gantry type marine automatic painting machine, comprising a mobile chassis 100, a gantry assembly 200, a telescopic arm 300, a painting assembly 400 and a driving mechanism 500. The mobile chassis 100 is used to drive the automatic painting machine to move. The gantry assembly 200 is vertically arranged on the mobile chassis 100. Figure 4 and Figure 5 The gantry assembly 200 includes a first gantry 210, a second gantry 220 and a third gantry 230. The first gantry 210 is mounted on the mobile chassis 100, the second gantry 220 is slidably connected to the first gantry 210, and the third gantry 230 is slidably connected to the second gantry 220. The telescopic boom 300 is slidably connected to the third gantry 230. The painting assembly 400 is used to paint the hull. The painting assembly 400 is mounted on the telescopic boom 300. The telescopic boom 300 is used to drive the painting assembly 400 to extend and retract horizontally. The telescopic boom 300 includes a telescopic drive component, which can be a telescopic cylinder or a motor screw module. The driving mechanism 500 is mounted on the mobile chassis 100. The driving mechanism 500 connects the gantry assembly 200 and the telescopic boom 300. The driving mechanism 500 is used to drive the second gantry 220, the third gantry 230 and the telescopic boom 300 to rise and fall.

[0041] The mobile chassis 100 enables flexible movement of the paint sprayer. The drive mechanism 500 drives the second and third gantry 220, 230, and telescopic boom to rise and fall. The first, second, and third gantry 210, 220, and 230 are slidably connected to each other. When the gantry assembly 200 is retracted, its overall height is low, its center of gravity is low, and its movement is smooth. When the gantry assembly 200 is extended, its overall height is high to accommodate the height of the ship to be painted. The telescopic boom 300 drives the paint sprayer assembly 400 to extend and retract horizontally. The paint sprayer assembly 400 can paint the ship's hull, effectively solving the problem of automated hull painting. It can be remotely controlled and operated automatically, improving operational efficiency and optimizing the working environment.

[0042] In some embodiments, see Figure 2 、 Figure 4 and Figure 5The drive mechanism 500 includes a drive assembly 510, a first transmission assembly 520, and a second transmission assembly 530. The drive assembly 510 is installed on the mobile chassis 100. The output end of the drive assembly 510 is connected to the second gantry 220. The drive assembly 510 is used to drive the second gantry 220 to rise and fall. The drive assembly 510 can be a hydraulic cylinder or a motor screw module. The first transmission assembly 520 connects the first gantry 210, the second gantry 220, and the third gantry 230. The first transmission assembly 520 is used to drive the third gantry 230 to rise and fall when the second gantry 220 is raised and lowered. The second transmission assembly 530 connects the telescopic boom 300, the second gantry 220, and the third gantry 230. The second transmission assembly 530 is used to drive the telescopic boom 300 to rise and fall when the third gantry 230 is raised and lowered.

[0043] The driving assembly 510 drives the second gantry 220 to rise and fall, drives the third gantry 230 to rise and fall through the first transmission assembly 520, and drives the telescopic arm 300 to rise and fall through the second transmission assembly 530, so that the overall length of the driving assembly 510 does not need to be too long to raise the overall height of the gantry assembly 200.

[0044] In some embodiments, see Figure 2 、 Figure 4 and Figure 5 The first transmission assembly 520 includes a first sprocket 521 and a first chain. The first sprocket 521 is rotatably connected to the top of the second door frame 220. One end of the first chain is connected to the bottom end of the third door frame 230. The middle part of the first chain is engaged with the first sprocket 521. The other end of the first chain is connected to the first door frame 210.

[0045] The driving assembly 510 drives the second gantry 220 to rise, and then drives the first sprocket 521 to rise. The first gantry 210 is fixed on the mobile chassis 100, so that the position of the other end of the first chain remains unchanged. The first sprocket 521 pulls the other end of the first chain to rise, and then drives the third gantry 230 to rise (during the rising process of the second gantry 220, the bottom end of the third gantry 230 gradually approaches the top of the second gantry 220).

[0046] The first transmission assembly 520 may further include a pulley and a steel wire rope. The pulley is rotatably connected to the top of the second gantry 220 . One end of the steel wire rope is connected to the first gantry 210 , and the other end passes around the pulley and is connected to the bottom of the third gantry 230 .

[0047] In some embodiments, see Figure 2 、 Figure 4 and Figure 5The gantry assembly 200 further includes a fourth gantry 240, which is slidably connected to the third gantry 230. The telescopic boom 300 is slidably connected to the fourth gantry 240. The second transmission assembly 530 includes a second sprocket 531, a third sprocket 532, a second chain, and a third chain. The second sprocket 531 is rotatably connected to the top of the third gantry 230. One end of the second chain is connected to the bottom of the fourth gantry 240. The middle portion of the second chain engages the second sprocket 531. The other end of the second chain is connected to the second gantry 220. The third sprocket 532 is rotatably connected to the top of the fourth gantry 240. One end of the third chain is connected to the telescopic boom 300. The middle portion of the third chain engages the third sprocket 532. The other end of the third chain is connected to the third gantry 230.

[0048] The drive mechanism 500 drives the second gantry 220 upward, and the first transmission assembly 520 drives the third gantry 230 upward relative to the second gantry 220. The second sprocket 531 on the third gantry 230 rises, gradually increasing the distance between the top end of the third gantry 230 and the top end of the second gantry 220. The distance between the second sprocket 531 and the second gantry 220 also gradually increases, causing the length of the second chain between the second sprocket 531 and the second gantry 220 to gradually increase, while the length of the second chain between the second sprocket 531 and the first gantry 210 to gradually decrease. This gradually decreases the distance between the bottom end of the fourth gantry 240 and the top end of the third gantry 230, causing the fourth gantry 240 to rise relative to the third gantry 230.

[0049] The fourth gantry 240 rises relative to the third gantry 230, gradually increasing the distance between the third sprocket 532 and the third gantry 230. This in turn gradually increases the length of the third chain between the third sprocket 532 and the third gantry 230, while correspondingly decreasing the length of the third chain between the third sprocket 532 and the telescopic boom 300. This gradually decreases the distance between the telescopic boom 300 and the top end of the fourth gantry 240, allowing the telescopic boom 300 to rise.

[0050] In some embodiments, see Figure 1 The mobile chassis 100 is also provided with a rangefinder, which is used to measure the distance between the mobile chassis 100 and the hull. The rangefinder can be a laser rangefinder or an ultrasonic rangefinder.

[0051] In some embodiments, participation Figure 1 and 2 The paint spraying assembly 400 includes a mounting rod 410 and multiple spray heads 420. The telescopic arm 300 is connected to the middle portion of the mounting rod 410. The multiple spray heads 420 are mounted on the mounting rod 410 and are used for spraying paint. The multiple spray heads 420 are arranged on the mounting rod 410 so that the multiple spray heads 420 can operate simultaneously, thereby improving the efficiency of spraying paint.

[0052] In some embodiments, see Figure 1 and 2 The telescopic boom 300 is pivotally connected to the middle portion of the mounting rod 410. The paint spray assembly 400 also includes a swing cylinder 430, one end of which is hinged to the telescopic boom 300 and the other end of which is hinged to the mounting rod 410. The swing cylinder 430, which can be a hydraulic cylinder, is used to swing the mounting rod 410. The swing cylinder 430 extends and retracts, swinging the mounting rod 410 so that the spray head 420 on the mounting rod 410 can adapt to the contours of the vessel.

[0053] In some embodiments, see Figure 1 The mobile chassis 100 is a wheeled chassis, and a mobile wheel 110 is provided below the mobile chassis 100. The mobile chassis 100 can also be a crawler chassis.

[0054] In some embodiments, see Figure 1 The gantry-type marine automatic paint spraying machine also includes a protective leg 120 and a leveling telescopic leg 130. One end of the protective leg 120 is hinged to the mobile chassis 100. A telescopic cylinder 121 is hinged to the protective leg 120, and the other end of the telescopic cylinder 121 is hinged to the mobile chassis 100. The telescopic leg 130 is telescopically connected to the mobile chassis 100. The protective leg 120 and the telescopic leg 130 ensure the ground-gripping stability of the mobile chassis 100 and the smooth painting of the paint spraying assembly 400.

[0055] In some embodiments, see Figure 4 The gantry-type marine automatic paint spraying machine also includes a gantry tie rod 600. One end of the gantry tie rod 600 is connected to the mobile chassis 100, and the other end is connected to the end of the first gantry 210 away from the mobile chassis 100. The gantry tie rod 600 is tilted in the vertical direction. The gantry tie rod 600 holds the gantry assembly 200 in place, ensuring that the gantry assembly 200 is vertically mounted on the mobile chassis 100 and providing support stability for the gantry assembly 200.
