Description

Technical Field

[0001] This utility model relates to the field of ship exterior spraying technology, and in particular to a multi-layer layout structure of equipment room for ship exterior spraying device. Background Technology

[0002] Both shipbuilding and repair operations involve exterior painting, which forms a paint film on the ship's surface to provide protection against corrosion and dirt, enhance aesthetics, and serve as a marking tool. There are two main methods for exterior painting: manual painting and automated painting.

[0003] Manual spraying refers to the painting operation performed by workers holding spray guns and working on aerial work platforms. Manual spraying has drawbacks such as low spraying efficiency, high risk of working at height, and uneven paint film thickness.

[0004] Automated spraying refers to the use of a ship exterior spraying device to automatically perform painting operations. This device mainly includes a mobile chassis, a tower fixed to the chassis, a telescopic boom mounted on the tower and capable of being raised and lowered, and spraying equipment installed at the front end of the telescopic boom. For example, Chinese invention patent application number 202110573747.6 discloses an automated operation platform for ship painting. However, this automated operation platform has an equipment room and an operator's room mounted on top of the vehicle body. These are located on the same floor, meaning the equipment room on top of the vehicle body is a single-story structure. This layout is not compact, causing the vehicle body to occupy a large amount of space, which is detrimental to the movement of the ship exterior spraying device within the dock. While a multi-story structure would make the layout more compact, the higher levels of the equipment room, beyond the first floor, present a high risk factor for maintenance and repair of the internal equipment.

[0014] Furthermore, a preferred embodiment of the multi-layer layout structure between equipment rooms is as follows: the main body of both the fixed maintenance platform and the retractable maintenance platform includes a platform grid and a platform connecting frame fixed to the periphery of the platform grid. The platform connecting frame of the fixed maintenance platform is fixed to the supporting base frame, and the platform connecting frame of the retractable maintenance platform is hinged to the supporting base frame.

[0015] Furthermore, a preferred embodiment of the multi-layer layout structure of the equipment room is as follows: in two adjacent equipment rooms, the supporting base of the upper equipment room is fixed to the main body of the lower equipment room by several bolts, the supporting base of the upper equipment room is provided with several positioning holes, and the top of the main body of the lower equipment room is fixed with several positioning columns, which are inserted into the positioning holes one by one.

[0073] This utility model provides a multi-layer layout structure for equipment rooms in a ship exterior painting device, used for the layout of multiple equipment rooms 10 in the ship exterior painting device. The ship exterior painting device is used to automatically paint the ship's exterior. During the painting process, the ship exterior painting device moves along a path parallel to the curve of the ship's exterior. For ease of description, in the following embodiments, the direction of movement of the ship exterior painting device is defined as the left-right direction, and the horizontal direction perpendicular to the direction of movement of the ship exterior painting device is defined as the front-back direction. Therefore, the front-back direction is also the parallel direction between the ship exterior painting device and the ship's exterior.

[0074] like Figure 1 As shown, the ship exterior painting device includes a traveling chassis 61, a tower 62, a lifting drive source 63 (preferably a winch), a lifting transmission mechanism 64 (preferably a wire rope pulley mechanism), a tower 65, a telescopic boom 66, and painting equipment 67. Among them, as... Figure 2 and Figure 3 As shown, a drive wheel 68 is installed on the front and rear sides of the chassis 61. Each drive wheel 68 includes a wheel-side reducer 681 mounted on the chassis 61 and a rotatable drive wheel body 682. The wheel-side reducer 681 and the drive wheel body 682 are coaxially arranged, and the output end of the wheel-side reducer 681 is fixedly connected to the drive wheel body 682 by several bolts. The wheel-side reducers 681 of the two drive wheels 68 are independent of each other, thus independently controlling the rotation of each drive wheel 68. This drives the chassis 61 to move along a path parallel to the curve of the ship's exterior, which in turn drives the entire ship exterior painting device to move along a path parallel to the curve of the ship's exterior. Therefore, the movement path of the chassis 61 is also the movement path of the entire ship exterior painting device. The tower 62 is a multi-section structure assembled vertically, and the bottom of the tower 62 is fixed to the top surface of the chassis 61. A lifting drive source 63 is fixed to the top surface of the traveling chassis 61. A tower 65 is jacked up and lowered on a tower 62. The lifting drive source 63 is connected to the tower 65 via a lifting transmission mechanism 64, driving the tower 65 to rise and fall. A telescopic boom 66 can extend and retract horizontally in the forward and backward direction. The rear end of the telescopic boom 66 is fixedly connected to the tower 65, and the painting equipment 67 is installed at the front end of the telescopic boom 66. During the ship's exterior painting operation, the lifting drive source 63 drives the tower 65 and the telescopic boom 66 to rise and fall together via the lifting transmission mechanism 64. The telescopic boom 66 extends forward, allowing the painting equipment 67 to move to the target area. Combined with the movement and travel of the traveling chassis 61, automatic painting of the ship's exterior can be performed.

[0075] Furthermore, such as Figure 1 As shown, several equipment rooms 10 of the ship's exterior painting system are mounted on top of the traveling chassis 61. Figure 2 and Figure 3 ,as well as Figure 5 and Figure 6As shown, in the multi-layer layout structure of the equipment rooms involved in this application, multiple equipment rooms 10 are arranged in a multi-layer manner from top to bottom, with at least one equipment room per layer; when one equipment room 10 is configured on each layer, the multiple equipment rooms 10 are arranged in a single-row multi-layer manner; when several equipment rooms 10 are configured on each layer, the multiple equipment rooms 10 are arranged in a multi-row multi-layer manner, and the several equipment rooms 10 on each layer are arranged side by side on the left and right sides in the traveling direction of the traveling chassis 61. Each equipment room 10 includes a support frame 11, a room body 12 fixed on the support frame 11, and a ladder 13 installed on the outer surface of the room body 12. The support frame 11 is provided with fixed maintenance platforms 14 distributed around the periphery of the room body 12. Multiple equipment rooms 10 include a bottom-level equipment room 20 distributed at the lowest level, and upper-level equipment rooms 30 excluding the bottom-level equipment room 20. The support frame 11 of the bottom-level equipment room 20 is fixed on the traveling chassis 61 of the ship's exterior painting device, thereby fixing the bottom-level equipment room 20 as a whole to the top of the traveling chassis 61. The fixed maintenance platform 14 of the upper-level equipment room 30 is provided with a maintenance passage 31 that runs vertically through the room. In two adjacent equipment rooms 10, the support frame 11 of the upper equipment room 10 is fixed on the top of the main room 12 of the lower equipment room 10, thereby fixing the upper equipment room 10 as a whole to the top of the lower equipment room 10. The upper end of the ladder 13 of the lower equipment room 10 is set close to the maintenance passage 31 of the upper equipment room 10.

[0076] In the multi-layer layout structure of the equipment room involved in this application, the multiple equipment rooms 10 of the ship exterior painting device are arranged in a multi-layer structure in the vertical direction, making the layout of the multiple equipment rooms 10 more compact and reducing the space occupied; when the multiple equipment rooms 10 are arranged in multiple rows, they are set in multiple rows in the walking direction of the ship exterior painting device, reducing the space occupied in the front and rear directions, and facilitating the painting operation of the ship exterior painting device in the dock. Meanwhile, when maintenance and repair are required for each equipment room 10, maintenance personnel can directly climb onto the fixed maintenance platform 14 of the bottom equipment room 20 to facilitate maintenance and repair work on the bottom equipment room 20. In particular, each equipment room 10 has a ladder 13 on the outer surface of the main body 12, and the fixed maintenance platform 14 of the upper equipment room 30 has a maintenance passage 31 adjacent to the ladder 13 of the lower equipment room 10. Maintenance personnel standing on the fixed maintenance platform 14 of the lower equipment room 10 can enter the maintenance passage 31 of the upper equipment room 10 through the ladder 13 of the equipment room 10, and then enter the fixed maintenance platform 14 of the upper equipment room 10, which facilitates maintenance personnel to carry out maintenance and repair work on the upper equipment rooms 30 that are not on the bottom floor. Therefore, this application provides a fixed maintenance platform 14 for maintenance personnel to stand on in each equipment room 10, and facilitates access to the fixed maintenance platforms 14 in each upper-level equipment room 30 via ladders 13 and maintenance access channels 31, thereby significantly improving operational safety. Preferably, each upper-level equipment room 30 has an openable and closable flap in its maintenance access channel 31; after maintenance personnel climb onto the fixed maintenance platform 14 of that level, they can close the flap to shut off the maintenance access channel 31, preventing falls and further enhancing safety.

[0077] Furthermore, in this application, such as Figure 2 and Figure 3As shown, there are four equipment rooms 10, arranged in two rows on the left and right sides in the direction of travel of the chassis 61. Specifically, the four equipment rooms 10 of the ship exterior painting device are a hydraulic room 71, a power room 72, an operation room 73, and a paint room 74. Among them, the hydraulic room 71 is equipped with a hydraulic station and an air compressor, and is located on the second floor of the right row; the power room 72 is equipped with a diesel generator set, and is located on the second floor of the left row; the operation room 73 is equipped with an operation platform, a control console, etc., and is located on the bottom floor of the left row; the paint room 74 is equipped with an air tank, a paint delivery pump, etc., and is located on the bottom floor of the right row. Therefore, the left-hand equipment room 10 on the traveling chassis 61 is the ground floor operator room 73 and the second-floor power room 72, and the right-hand equipment room 10 on the traveling chassis 61 is the ground floor paint room 74 and the second-floor liquid air room 71. The operator room 73 and the paint room 74 are both fixed to the top of the traveling chassis 61, the power room 72 is fixed to the top of the operator room 73, and the liquid air room 71 is fixed to the top of the paint room 74. The operator room 73 and the paint room 74 are both ground floor equipment rooms 20, and the power room 72 and the liquid air room 71 are both upper floor equipment rooms 30.

[0078] Furthermore, each equipment room 10 (i.e., the liquid air room 71, the power room 72, the operation room 73, and the paint room 74) has integrated connectors 80 on its outer surface. Each equipment room 10's connectors 80 are electrically connected to its internal equipment, connected via hydraulic lines, and connected via air pipes. This allows each equipment room 10 to be hoisted individually, facilitating its transfer. Inside the dock, each equipment room 10 is hoisted onto the traveling chassis 61 for assembly. After assembly, the connectors 80 enable various connections between the equipment rooms 10, facilitating both the transfer of each equipment room 10 and the on-site connection of multiple equipment rooms 10 via external wiring, making operation convenient.

[0079] Furthermore, such as Figure 2 and Figure 3 As shown, the fixed maintenance platform 14 is located on the left or right side of the main body 12 of the ship's exterior, along the traveling direction of the chassis 61. Preferably, the fixed maintenance platforms 14 of the liquid air room 71 and the paint room 74 are both located on the right side of their respective main bodies 12, while the fixed maintenance platforms 14 of the power room 72 and the operation room 73 are both located on the left side of their respective main bodies 12. This avoids excessive width in the forward and backward directions, thereby preventing collisions with other equipment in the dock and facilitating the movement of the entire ship exterior painting equipment within the dock.

[0080] Furthermore, such as Figure 2 and Figure 3As shown, along the direction perpendicular to the traveling direction of the chassis 61, the high-rise equipment room 30 is equipped with retractable maintenance platforms 40 on both the front and rear sides of its main room 12. Similarly, the front and rear sides of the liquid air room 71, and the front and rear sides of the power room 72 are also equipped with retractable maintenance platforms 40. Figures 5 to 7 As shown, the retractable maintenance platform 40 includes a retractable drive mechanism 41 mounted on the support base 11, a maintenance platform body 42 hinged to the outer side of the support base 11, a first handrail 43 hinged to the outer side of the maintenance platform body 42, and a linkage mechanism 44. The retractable drive mechanism 41 is connected to the maintenance platform body 42, driving the maintenance platform body 42 to retract or unfold. One end of the maintenance platform body 42 extends to the fixed maintenance platform 14. The linkage mechanism 44 is connected to the maintenance platform body 42, the first handrail 43, and the room body 12. When not performing maintenance, the retractable drive mechanism 41 drives the maintenance platform body 42 to retract. At this time, as... Figure 7 As shown, the main body 42 of the maintenance platform fits against the front and rear sides of the main body 12 of the room, without occupying extra space. When maintenance is required, the retraction drive mechanism 41 drives the main body 42 of the maintenance platform to unfold. At this time, as shown... Figure 8 As shown, maintenance personnel can walk from the fixed maintenance platform 14 to the main body 42 of the retractable maintenance platform 40, which facilitates maintenance on both the front and back sides of the main body 12 of the room and improves operational safety.

[0081] Furthermore, the preferred structure of the retraction drive mechanism 41 is as follows: Figures 5 to 7 As shown, the retraction drive mechanism 41 includes a support column 411 fixed to the support base 11, a drive mounting base 412 fixed to the upper end of the support column 411, a retraction drive source mounted on the drive mounting base 412, a roller 413 rotatably mounted on the drive mounting base 412, and a pull rope 414 wound around the outer circumference of the roller 413. The retraction drive source is connected to the roller 413 and drives the roller 413 to rotate. The outer end of the pull rope 414 is fixedly connected to the outer side of the maintenance platform body 42. The retraction drive source is a reducer, and the output shaft of the reducer is coaxial with and fixed to the roller 413; or, the retraction drive source is a handwheel, and the output shaft of the handwheel is coaxial with and fixed to the roller 413. Thus, in Figure 7 In the retracted state shown, when the retraction drive source drives the roller 413 to rotate to release the pull rope 414, the maintenance platform body 42, under the action of gravity, flips outward and downward relative to the supporting base 11, thereby unfolding the maintenance platform body 42 and causing it to flip to... Figure 8 The flattened state shown. Conversely, in... Figure 8In the flattened state shown, when the retraction drive source drives the roller 413 to rotate and retract the pull rope 414, the pull rope 414 pulls the maintenance platform body 42, causing the maintenance platform body 42 to flip inward and upward relative to the support base 11, thereby retracting the maintenance platform body 42 and causing it to flip to... Figure 7 The collapsed state is shown.

[0082] Furthermore, such as Figures 5 to 7 As shown, in the retractable maintenance platform 40, there are two sets of linkage mechanisms 44, located on the left and right sides of the main body 12 of the room, respectively; of course, another set of linkage mechanisms 44 can also be set in the middle. Each set of linkage mechanisms 44 includes a first link 441 and a second link 442. The first link 441 is fixed to the first handrail 43. The lower and upper ends of the first link 441 are hinged to the main body 42 of the maintenance platform and one end of the second link 442, respectively. The other end of the second link 442 is hinged to the main body 12 of the room. The linkage mechanism 44 moves with the rotation of the main body 42 of the maintenance platform. When the main body 42 of the maintenance platform is unfolded, as... Figure 8 As shown, the linkage mechanism 44 also unfolds, increasing the reliability of supporting the main body 42 of the maintenance platform; when the main body 42 of the maintenance platform is retracted, as... Figure 7 As shown, linkage 44 is also in the retracted state.

[0083] Furthermore, such as Figure 2 and Figure 3 As shown, both the fixed maintenance platform 14 and the retractable maintenance platform 40 include a platform grid 51 and a platform connecting frame 52 fixed to the outer periphery of the platform grid 51. The platform connecting frame 52 of the fixed maintenance platform 14 is fixed to the supporting base frame 11, while the platform connecting frame 52 of the retractable maintenance platform 40 is hinged to the supporting base frame 11. The grid structure enhances the anti-slip, ventilation, and fire resistance properties of both the fixed maintenance platform 14 and the retractable maintenance platform 40.

[0084] Furthermore, in two adjacent equipment rooms 10, the supporting frame 11 of the upper equipment room 10 is fixed to the main body 12 of the lower equipment room 10 by several bolts. Additionally, as... Figure 4 As shown, the support frame 11 of the upper equipment room 10 has several positioning holes 15, and the top of the main body 12 of the lower equipment room 10 has several positioning columns 16. The positioning columns 16 are inserted into the positioning holes 15 one by one, which plays a good positioning role when installing the upper equipment room 10.

[0085] Furthermore, such as Figure 2 and Figure 3As shown, each equipment room 10 is equipped with a second handrail 17 fixed to the supporting frame 11 around the perimeter of the fixed maintenance platform 14. The front side of the bottom equipment room 20 is also equipped with an extending ladder 13, which is fixed to the supporting frame 11 of the bottom equipment room 20 and located at the fixed maintenance platform 14 of the bottom equipment room 20, facilitating maintenance personnel to climb onto the fixed maintenance platform 14 of the bottom equipment room 20. Figure 5 and Figure 6 As shown, the top periphery of the equipment room 10 on the uppermost level is provided with a third handrail 18 fixed to the main body of the room 12. A top inspection port 19 is formed between the two ends of the third handrail 18. The upper end of the ladder 13 on the outer surface of the main body of the room 12 is set close to the top inspection port 19 on the top of the main body of the room 12, so as to facilitate maintenance work on the top of the equipment room 10 on the uppermost level.

[0086] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0087] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
