Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and in particular to a high-pressure spraying device for ship processing. Background Technology

[0002] Inside a ship, pipes that come into direct contact with seawater are critical components ensuring the normal operation of core systems such as power, ballast, and cooling. Typical applications include seawater cooling system pipes (providing cooling medium for engines, generators, and other equipment) and ballast water system pipes (regulating the ship's draft and stability). These pipes are constantly immersed in seawater, and before being installed inside the ship, they require internal coating to prevent seawater corrosion.

[0003] However, when spraying the inner wall of such pipes, from an operational perspective, the pipe inner diameter is different, and personnel cannot directly enter, making the operation inconvenient and inefficient. When using tools, uneven feeding speed can easily lead to coating ripple defects, affecting the anti-corrosion performance of the pipe. Utility Model Content

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a high-pressure spraying device for ship processing, including a bottom crossbeam 1 and an electric cylinder 5. A moving mechanism 3 is fixedly connected to the upper side of the bottom crossbeam 1, and a rotating mechanism 2 is arranged above the moving mechanism 3. The electric cylinder 5 is vertically fixedly installed in the middle of the upper side of the rotating mechanism 2. A spraying mechanism 4 is fixedly connected to the upper side of the movable rod of the electric cylinder 5. The spraying mechanism 4 includes a pump body 41, a telescopic pipe 42, a metal branch pipe 43, a vertical frame 44, and a nozzle 45. The vertical frame 44 is fixedly connected to the movable rod of the electric cylinder 5. The nozzle 45 is fixedly connected to the groove in the middle of the vertical frame 44 by a nut. Multiple sets of nozzles 45 are fixedly connected to the metal branch pipe 43. The telescopic pipe 42 is fixedly connected to the lower end of the metal branch pipe 43. The telescopic pipe 42 is movably connected to the output end of the pump body 41. The pump body 41 is externally connected to a paint source.

[0019] The specific setup and function of this embodiment are described below: The vertical frame 44 is vertically fixed to the top of the movable rod of the electric cylinder 5. A mounting groove adapted to the nozzle 45 is opened in the middle of the vertical frame 44. Multiple sets of nozzles 45 are detachably fixed in the groove by nuts, and all nozzles 45 are arranged in a parallel configuration. This setup ensures that the nozzles 45 are in a fixed position, preventing displacement during spraying, and also facilitates adjustment of the number or spacing of nozzles 45 according to the inner diameter of the pipe. The metal branch pipe 43 has a multi-channel structure, with one end paired with each set of nozzles 45. The other end of the nozzle 45 is fixedly connected to the telescopic pipe 42, and its function is to evenly distribute the paint to each group of nozzles 45, ensuring that the paint output of multiple nozzles 45 is consistent. The telescopic pipe 42 is made of flexible and pressure-resistant material. In addition to fixing and connecting the metal branch pipe 43 to the output end of the pump body 41, it also needs to be reserved with sufficient length and wrapped around the outside of the electric cylinder 5. This setting can adapt to the telescopic movement of the electric cylinder 5 and the rotation movement driven by the rotating mechanism 2, and avoid the telescopic pipe 42 being pulled and broken during pipeline spraying. The pump body 41 needs to have high pressure delivery capacity and be able to... A large-capacity paint source is connected to the pipeline. Its function is to extract external paint and pressurize it to provide the paint pressure required for high-pressure spraying of the nozzle 45. The electric cylinder 5 is vertically fixed to the middle of the upper side of the rotating mechanism 2. The extension and retraction stroke of its movable rod needs to be adapted to the length of common vertical pipes. Its function is to drive the spraying mechanism 4 to move up and down as a whole. It can both cooperate with the gantry crane to adjust the initial position of the nozzle 45 so that the lower nozzle 45 is flush with the highest point of the inner wall of the pipe, and slowly retract during the spraying process to form a spiral spraying trajectory in coordination with the action of the gantry crane lifting the pipe. The rotating mechanism 2 is set above the moving mechanism 3. Its load-bearing structure needs to meet the weight support requirements of the electric cylinder 5 and the spraying mechanism 4. Its function is to provide rotational power for the electric cylinder 5 to drive the spraying mechanism 4 to perform circular motion. The moving mechanism 3 is fixed to the upper side of the bottom crossbar 1. Its moving direction needs to be perpendicular to the pipe axis. Its function is to drive the rotating mechanism 2, the electric cylinder 5 and the spraying mechanism 4 to move in a straight line. With the fine adjustment of the gantry crane, the electric cylinder 5 is precisely positioned in the center area of ​​the pipe, ensuring that the nozzle 45 is located at the center of the pipe.

[0020] Example 2: Figure 1 - Figure 4As shown, the rotating mechanism 2 includes a support platform 21, a reduction motor 22, a gear ring 23, and a first gear 24. The pump body 41 is fixedly connected to the upper side of the support platform 21. The gear ring 23 is rotatably connected to the central protrusion of the support platform 21 through a bearing. The first gear 24 meshes with the outer side of the gear ring 23. The reduction motor 22 is fixedly installed on the lower side of the support platform 21. The output shaft of the reduction motor 22 passes through the upper side of the support platform 21 and is fixedly connected to the first gear 24. The moving mechanism 3 includes a servo motor 31, a second gear 32, a rack 33, and a guide rail assembly 34. The servo motor 31 is vertically inverted and fixedly installed on one side of the support platform 21. The support platform 21 is slidably connected to the upper side of the bottom crossbeam 1 through the guide rail assembly 34 installed below it. The rack 33 is fixedly connected to the upper side of the bottom crossbeam 1. The rack 33 and the guide rail assembly 34 are parallel to each other. The second gear 32 meshes with one side of the teeth of the rack 33. The second gear 32 is fixedly installed on the output shaft of the servo motor 31.

[0021] The overall effect of this embodiment is that the coordinated operation of the rotating mechanism 2 and the moving mechanism 3 effectively solves the problems of "positioning accuracy" and "motion stability" in the spraying of the inner wall of the vertical pipe. On the one hand, the moving mechanism 3 is vertically inverted and mounted on one side of the support platform 21 by a servo motor 31. Its output shaft drives the second gear 32 to mesh with the rack 33 fixed on the bottom crossbeam 1. At the same time, the guide rail assembly 34 restricts the movement direction of the support platform 21, so that the support platform 21 can move in a uniform linear motion along the bottom crossbeam 1. With the small-distance movement of the gantry crane, the electric cylinder 5 can be quickly adjusted to the center area of ​​the pipe, ensuring that the nozzle 45 is always in the center position of the pipe and avoiding uneven spraying thickness caused by the offset of the nozzle 45. On the other hand, the rotating mechanism 2 drives the first gear 24 to mesh with the gear ring 23 by a reduction motor 22. Under the support of the bearing, the gear ring 23 can drive the electric cylinder 5 to rotate smoothly, thereby making the multiple sets of nozzles 45 on the vertical frame 44 move in a uniform arc, providing a spiral spraying trajectory. Stable rotational power; in addition, the support platform 21 serves as both the mounting base for the rotating mechanism 2 and a fixed support for the pump body 41, realizing the integrated layout of the rotating, moving, and spraying components; overall, the structural configuration of this embodiment enables the device to work with the gantry crane to complete the automated spraying of the inner wall of the vertical pipe. Through the linear positioning of the moving mechanism 3 and the circular motion of the rotating mechanism 2, combined with the lifting and lowering coordination of the electric cylinder 5 and the gantry crane, a continuous spiral spraying trajectory can be formed. At the same time, the winding design of the telescopic tube 42 can adapt to forward and reverse spraying, spraying the first pipe clockwise and the second pipe counterclockwise, avoiding the breakage of the telescopic tube 42, ensuring stable coating delivery, and ultimately achieving uniformity, efficiency, and safety of the inner wall spraying of the pipe, meeting the strict requirements for the quality of inner wall spraying in shipbuilding.

[0022] The device's operation and working principle are as follows: The device is installed in the workshop, below the workshop gantry crane. The gantry crane vertically lifts the pipe, positioning it directly above the spraying mechanism 4. The gantry crane lowers the pipe to the desired height while simultaneously extending the electric cylinder 5. The pipe and spraying mechanism 4 move relative to each other, aligning the lowest nozzle 45 with the highest point of the pipe's inner wall. The electric cylinder 5 is positioned according to the pipe's length. The servo motor 31 is activated, driving the second gear 32 to rotate, while the rack 33 remains fixed. After the second gear 32 meshes with the rack 33, it moves along the length of the rack 33. With the cooperation of the guide rail assembly 34, the support platform 21 moves linearly along the bottom crossbar 1, simultaneously coordinating with the gantry crane's small-distance movements. This positions the electric cylinder 5 in the center of the pipe, ensuring the nozzle 45 is located at the pipe's center. Then... The control motor 22 starts and drives the first gear 24 to rotate. The first gear 24 meshes with the gear ring 23. Under the action of the bearing, the gear ring 23 rotates outside the protrusion of the support platform 21, thereby driving the electric cylinder 5 installed on it to rotate, which in turn drives the vertical frame 44 to rotate, causing multiple sets of nozzles 45 to move in an arc. At this time, the pump body 41 starts, draws in the external paint and pressurizes it. After being transported through the telescopic pipe 42 and the metal branch pipe 43, the paint is sprayed from multiple sets of parallel nozzles 45 onto the inner wall of the pipe. With the slow lifting of the pipe by the gantry crane and the slow retraction of the electric cylinder 5, the inner wall of the vertical pipe is uniformly sprayed in a spiral trajectory. The telescopic pipe 42 is wrapped around the outside of the electric cylinder 5 and is very long. After the first inner wall of the pipe is sprayed clockwise, the second inner wall of the pipe is sprayed counterclockwise, and so on, to avoid the telescopic pipe 42 breaking and to ensure stable delivery of the paint.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
