The working end of the intermittent closing mechanism 100 is connected to the arc guide rod 9 to facilitate the simultaneous adjustment of the positions of the arc guide rods 9 on both sides on the arc sleeve 8, so that the arc sleeve 8 and the arc guide rod 9 are used to spray the surface of the handrail 2 when they move along the steps. The stepless adjustment mechanism 200 is arranged on the longitudinal positioning rod 4 and the fixed cross bar 5. The working end of the stepless adjustment mechanism 200 abuts against the intermittent closing mechanism 100, so that the intermittent closing mechanism 100 maintains stable movement when the spacing between the arc sleeves 8 on both sides changes. The spraying system 300 is provided with multiple groups, one end of the spraying system 300 is connected to the arc guide rod 9, and is used to spray the surface of the inclined ladder frame 1 and the handrail 2. The other end of the spraying system 300 is also arranged on the side of the traveling equipment 3, and is used to spray the surface of the inclined ladder steps.

[0043] The present application provides an anti-corrosion spraying device for a marine inclined ladder, which has the characteristics of a high degree of automation, does not require manual spraying, can greatly improve the efficiency of spraying, can spray the handrail 2 and the step surface at the same time, and while passing the inclined ladder frame 1 one by one, utilizes the intermittent closing mechanism 100 and the spraying system 300 to continuously spray the side of the inclined ladder frame 1, and the spraying distance can be controlled during the spraying process, so that the inclined ladder frame 1, the handrail 2 and the step surface can be sprayed more evenly, thereby ensuring the quality of the coating.

[0044] In one example of the present invention, guide rods 6 are slidably installed at both ends of the fixed cross bar 5, and the ends of the guide rods 6 are fixedly connected to the arc sleeve 8. The fixed cross bar 5 and the guide rod 6 are provided with limit holes with the same aperture, and the positions of the guide rod 6 and the arc sleeve 8 are fixed when the insertion rod 7 is inserted; in addition, when the fixed cross bar 5 and the guide rod 6 are replaced by components similar to cylinders, the cylinders are connected to the control equipment to realize the adjustment of adjacent arc sleeves 8, and the handrails 2 with changed spacing can be continuously sprayed in combination with the stepless adjustment mechanism 200; at the same time, the traveling equipment 3 uses the existing step climbing device, and it only needs to ensure that the spacing between the arc sleeve 8 and the handrail 2 is constant during the traveling process.

[0045] like Figure 1 , Figure 3 and Figure 4 As shown, as a preferred embodiment of the present invention, the intermittent closing mechanism 100 includes a transmission shaft 10, a driving gear 11, a mounting seat 12, a transmission shaft 2 13, a driven gear 14, a pulley 15 and a synchronous belt 16;

[0046] The transmission shafts 10 are rotatably mounted in pairs on the fixed crossbar 5, and mutually meshing driving gears 11 are mounted on the transmission shafts 10 on both sides;

[0047] The mounting seat 12 is symmetrically mounted on the opposite side of the arc sleeve 8, and a transmission shaft 2 13 is rotatably mounted on the mounting seat 12. A pulley 15 is mounted on the transmission shaft 2 13 and the transmission shaft 1 10 in the same plane, and the pulleys 15 on the transmission shaft 1 10 and the transmission shaft 2 13 are connected by a synchronous belt 16.

[0048] A driven gear 14 is also installed at the end of the transmission shaft 13, and the driven gear 14 is meshed with a partial outer gear ring arranged outside the arc-shaped guide rod 9, and is used to push the arc-shaped guide rod 9 to slide along the arc-shaped sleeve 8 when the driven gear 14 rotates.

[0049] In one example of the present invention, the transmission shaft 10 is driven by an external micro motor, which is also connected to a remote control device and drives the transmission shaft 10 on one side to rotate along the fixed cross bar 5 when the micro motor is working. Since the driving gears 11 on both sides are engaged, the transmission shafts 10 on both sides can rotate in opposite directions. The transmission shaft 10 also drives the transmission shaft 2 13 to rotate along the mounting seat 12 through the synchronous belt 16. The driven gear 14 pushes the arc guide rod 9 to slide along the arc sleeve 8 during the movement with the transmission shaft 2 13, so as to smoothly cross the inclined ladder frame 1.

[0050] like Figure 1 , Figure 2 and Figure 5 As shown, as another preferred embodiment of the present invention, the stepless adjustment mechanism 200 includes a longitudinal slot 17, a positioning column 18, a diagonal tie rod 19, a positioning column 20, a horizontal slot 21 and an adjustment wheel 22;

[0051] The longitudinal groove 17 is arranged along the height direction of the longitudinal positioning rod 4, a positioning column 18 is slidably installed in the longitudinal groove 17, and two inclined rods 19 are hinged on the positioning column 18;

[0052] A second positioning column 20 is installed at the top of the inclined tie rod 19, and the second positioning column 20 is slidably connected to a horizontal groove 21 provided on the fixed cross bar 5;

[0053] An adjusting wheel 22 is rotatably arranged on the inclined tie rod 19 , and the adjusting wheel 22 abuts against the inner side of the synchronous belt 16 .

[0054] In one example of the present invention, the positioning column 18 is driven by a telescopic member separately arranged in the longitudinal groove 17, and the telescopic member can be selected from linear drive devices such as cylinders, hydraulic cylinders, electric cylinders and electric telescopic rods in actual use. When the spacing between adjacent arc sleeves 8 needs to be adjusted, the telescopic member pulls the positioning column 18 to slide along the longitudinal groove 17, and the positioning column 18 also drives the positioning column 20 to slide along the horizontal groove 21 through the inclined rod 19. The adjusting wheel 22 moves synchronously with the inclined rod 19, and the adjusting wheel 22 rotates during the movement with the synchronous belt 16 to maintain the tightness of the synchronous belt 16.

[0055] like Figure 1 As shown, as another preferred embodiment of the present invention, the spraying system 300 includes a liquid storage tank 23, a liquid delivery pipe 24, a nozzle 1 25 and a nozzle 2 26;

[0056] The liquid storage tank 23 is installed on the top of the fixed cross bar 5, and the two sides of the nozzle 1 25 are connected with the infusion tube 24;

[0057] A plurality of nozzles 1 25 are evenly installed on the inner side of the arc-shaped sleeve 8, and a plurality of nozzles 2 26 are evenly installed on the inner side of the arc-shaped guide rod 9;

[0058] A flow channel 1 is provided inside the arc sleeve 8 , a flow channel 2 is provided inside the arc guide rod 9 , and the flow channel 1 and the flow channel 2 are communicated with each other. The flow channel 1 is communicated with the infusion tube 24 and the nozzle 1 25 , and the flow channel 2 is communicated with the nozzle 2 26 .

[0059] In one example of the present invention, when the arc sleeve 8 and the arc guide rod 9 pass over the inclined ladder frame 1 and move along the handrail 2, the pump body built into the liquid storage tank 23 causes the spray slurry to flow along the infusion tube 24, and the spray slurry moves along the flow channel 1 set in the arc sleeve 8 and is sprayed out from the nozzle 1 25. The spray slurry also enters the flow channel 2 in the arc guide rod 9 along the flow channel 1, and is finally sprayed out from the nozzle 2 26. The nozzle 1 25 cooperates with the guide rod 6 to realize all-round spraying of the surface of the handrail 2.

[0060] like Figure 1 and Figure 6 As shown, as another preferred embodiment of the present invention, the spraying system 300 further includes a longitudinal rod 1 27, a longitudinal rod 28, a spray hole 1 29 and a laser position finder 30;

[0061] The longitudinal rod 1 27 and the longitudinal rod 28 are symmetrically installed on both sides of the arc-shaped guide rod 9 along the height direction;

[0062] A flow channel 3 is provided in the longitudinal rod 1 27 and the longitudinal rod 2 28, a valve body for controlling flow is installed in the flow channel 3, the flow channel 3 is communicated with a spray hole 1 29 provided on the outer sides of the longitudinal rod 1 27 and the longitudinal rod 2 28, and the spray hole 1 29 is arranged obliquely;

[0063] A laser position finder 30 is fixedly installed on the side of the longitudinal rod 27, and the laser position finder 30 is electrically connected to the valve body. The laser position finder 30 dynamically monitors the distance between the longitudinal rod 27 and the inclined ladder frame 1.

[0064] In one example of the present invention, the longitudinal rod 1 27 and the longitudinal rod 28 also move synchronously with the arc guide rod 9, and during the movement, the position between the longitudinal rod 1 27 and the inclined ladder frame 1 is monitored by a laser position finder 30. At the moment when the longitudinal rod 1 27 or the longitudinal rod 28 passes through the inclined ladder frame 1, the valve body receives the signal transmitted by the laser position finder 30 and is in an open state, and the spray slurry is sprayed onto the surface of the inclined ladder frame 1.

[0065] like Figure 1 As shown, as another preferred embodiment of the present invention, the spraying system 300 further includes a connecting pipe 31 and a transverse spray pipe 32;

[0066] The transverse nozzle 32 is fixedly installed on the side of the traveling device 3, and the transverse nozzle 32 is connected to a flow channel 1 provided in the arc sleeve 8 through a connecting pipe 31;

[0067] The bottom end of the transverse nozzle 32 is also evenly arranged with a plurality of spray holes 2 to facilitate spraying of the step surface.

[0068] In one example of the present invention, the spray slurry flowing in the flow channel 1 in the arc sleeve 8 enters the transverse nozzle 32 along the connecting pipe 31, and is finally sprayed out from the spray hole 2 set at the bottom of the transverse nozzle 32. The spray hole 2 is arranged in conjunction with the moving equipment 3, so that the surface of the moving equipment 3 can be sprayed while the moving equipment 3 moves along the steps.

[0069] In summary, when in use, the traveling device 3 is placed on the step, the positions of the arc sleeve 8 and the arc guide rod 9 are adjusted according to the spacing between adjacent handrails 2, and the provided insertion rod 7 is used to complete the fixing work of the fixed cross bar 5 and the insertion rod 7. The telescopic member pulls the positioning column 18 to slide along the longitudinal groove 17, and the positioning column 18 also drives the positioning column 20 to slide along the horizontal groove 21 through the inclined rod 19. The adjusting wheel 22 moves synchronously with the inclined rod 19, and the adjusting wheel 22 rotates during the movement with the synchronous belt 16 to maintain the tightness of the synchronous belt 16. When the arc sleeve 8 and the arc guide rod 9 are between adjacent inclined ladder frames 1, the traveling device 3 drives The whole handrail 2 moves along the step surface, and the pump body built into the liquid storage tank 23 allows the spray slurry to flow along the infusion tube 24. The spray slurry moves along the flow channel 1 set in the arc sleeve 8 and is sprayed from the nozzle 1 25. The spray slurry also enters the flow channel 2 in the arc guide rod 9 along the flow channel 1, and is finally sprayed from the nozzle 26. The nozzle 1 25 cooperates with the guide rod 6 to realize the all-round spraying of the surface of the handrail 2. When the arc sleeve 8 and the arc guide rod 9 pass through the inclined ladder frame 1, the position between the longitudinal rod 1 27 and the inclined ladder frame 1 is monitored by the laser position finder 30. At the moment when the longitudinal rod 1 27 or the longitudinal rod 28 passes through the inclined ladder frame 1, the laser position finder 30 feeds back to the external The micro motor drives the transmission shaft 10 on one side to rotate along the fixed cross bar 5 when the micro motor is working. Due to the meshing of the driving gears 11 on both sides, the transmission shafts 10 on both sides can rotate in opposite directions. The transmission shaft 10 also drives the transmission shaft 2 13 to rotate along the mounting seat 12 through the synchronous belt 16. The driven gear 14 pushes the arc guide rod 9 to slide along the arc sleeve 8 during the movement with the transmission shaft 2 13, so as to smoothly cross the inclined ladder frame 1. At the same time, the valve body receives the signal transmitted by the laser position finder 30 and is in the open state. The spray slurry is sprayed onto the surface of the inclined ladder frame 1. By repeating the above process, the spraying work on the surface of the inclined ladder frame 1 and the handrail 2 can be completed. When the traveling equipment 3 moves along the steps, the spray slurry flowing in the flow channel 1 in the arc sleeve 8 enters the transverse nozzle 32 along the connecting pipe 31, and is finally sprayed onto the surface of the traveling equipment 3 from the spray hole 2 set at the bottom of the transverse nozzle 32; the present device has the characteristics of high degree of automation, no manual spraying is required, and the spraying efficiency can be greatly improved. The handrail 2 and the step surface can be sprayed at the same time, and the side of the inclined ladder frame 1 can be continuously sprayed by using the intermittent closing mechanism 100 and the spraying system 300 when passing through the inclined ladder frame 1 one by one, and the spraying distance can be controlled during the spraying process, so that the inclined ladder frame 1, the handrail 2 and the step surface are sprayed more evenly, thereby ensuring the quality of the coating.
