[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0034] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0035] Ships are exposed to seawater corrosion during operation, making their hulls prone to rust. Therefore, regular maintenance is necessary. Rust removal is a crucial step in this process. During rust removal, a cleaning tray is installed on an aerial work platform. The operator constantly monitors the distance between the cleaning tray and the ship's surface, adjusting the platform's position in real time to maintain the appropriate distance.

[0036] In related technologies, the cleaning disc is installed on an aerial work platform via a connecting device, but the connecting device cannot be adapted to various sizes of aerial work platforms.

[0037] In view of the above problems, this application provides a connecting device and a cleaning device to solve the technical problem that the connecting device cannot adapt to a variety of different specifications of aerial work platforms.

[0038] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0039] Please refer to Figure 1 , Figure 2 and Figure 3 This application provides a connection device, including a mounting base 1, a connection component, and a first locking component 3.

[0040] Mounting base 1 is used to connect with the cleaning component, and mounting base 1 is provided with a fixing groove; the connecting component is located at the opening of the fixing groove, and the connecting component is used to connect the aerial work platform; the first locking component 3 includes a first slider 31 and a first locking member 32. The first slider 31 is slidably disposed in the fixing groove, and the first locking member 32 passes through the connecting component and is detachably connected to the first slider 31 to fix the position of the first slider 31 and connect the connecting component to the mounting base 1.

[0041] It should be noted that an aerial work platform includes a platform surface and a fence. The fence is fixed to the platform surface end to end, and the fence encloses the work area for the operators. Connecting components to the aerial work platform refer to the connection of the connecting components to the fence using connecting structures such as U-bolts and steel wires, allowing the connecting device to be mounted on the fence. For example, U-bolts are arranged around the perimeter of the crossbars on the fence, and both ends of the U-bolts are threaded with nuts, thus fixing the connecting component and the crossbars on the fence between the U-bolts and nuts, allowing the connecting component to be connected to the aerial work platform.

[0042] In the connecting device provided in this application embodiment, the first slider 31 is slidably disposed in the fixed groove, so that the relative position of the first slider 31 and the mounting base 1 can be changed, thereby changing the position of the connecting component connected to the mounting base 1 through the first locking fastener 32 and the first slider 31. The position of the connecting component can be adjusted according to the position of the connecting structure (the crossbar on the fence) on the aerial work platform, so that the connecting component can be connected to aerial work platforms of different specifications, thereby making the connecting device of this application embodiment adaptable to a variety of aerial work platforms of different specifications.

[0043] Please refer to Figure 1 In some embodiments, the mounting base 1 includes a telescopic assembly 12 and an extension rod 11, the telescopic assembly 12 and the extension rod 11 are connected, the fixing groove includes a first fixing groove 111 formed on the extension rod 11 and a second fixing groove 121 formed on the telescopic assembly 12, the connecting assembly includes a first connector 21 provided at the opening of the first fixing groove 111 and a second connector 22 provided at the opening of the second fixing groove 121, and the first locking assembly 3 is provided in at least two sets, one set of the first locking assembly 3 fixing the first connector 21 to the extension rod 11, and the other set of the first locking assembly 3 fixing the second connector 22 to the telescopic assembly 12.

[0044] With the above configuration, the telescopic component 12 is connected to one of the crossbars of the aerial work platform via a set of locking components and the first connecting member 21, and the extension rod 11 is connected to the other crossbar of the aerial work platform via a set of locking components and the second connecting member 22. This allows the connecting device to connect to two spaced-apart crossbars on the aerial work platform, ensuring a relatively stable connection between the connecting device and the aerial work platform. Furthermore, the distance between the first connecting member 21 and the second connecting member 22 can be flexibly adjusted, allowing the connecting device to adapt to various sizes of aerial work platforms.

[0045] Furthermore, in the above embodiments, the mounting base 1 is disassembled into a telescopic component 12 and an extension rod 11. This allows for the separate fabrication of the telescopic component 12 and the extension rod 11 before their assembly, or for the mounting base 1 to be disassembled into the telescopic component 12 and the extension rod 11 before maintenance, repair, and transportation, thus facilitating the production, maintenance, and transportation of the mounting base 1.

[0046] In some embodiments, the fixing groove has two oppositely arranged side walls, at least one side wall is provided with a stop portion 112, the stop portion 112 is located at the opening of the fixing groove, the first slider 31 is disposed on one side of the stop portion 112, the first locking fastener 32 is detachably connected to the first slider 31, and the stop portion 112 is clamped between the first locking fastener 32 and the first slider 31 to fix the position of the first slider 31 and fix the connecting assembly on the mounting base 1.

[0047] Please refer to Figure 3 In the above embodiment, the stop 112 prevents the first slider 31 from disengaging from the first fixing groove 111. When the first locking fastener 32 is connected to the first slider 31, the first locking fastener 32 and the first slider 31 can clamp the first connecting member 21 and the stop 112, so that the first connecting member 21 is connected to the extension rod 11 through the first locking fastener 32 and the first slider 31, and the first slider 31 will no longer slide relative to the first fixing groove 111, thereby fixing the position of the first slider 31 and the first connecting member 21. After the first locking fastener 32 and the first slider 31 are disassembled, the first slider 31 can slide relative to the first fixing groove 111, so that the position of the first slider 31, the first locking fastener 32 and the first connecting member 21 can be adjusted.

[0048] Please refer to Figure 5 In the above embodiment, the stop portion 112 can prevent the first slider 31 from disengaging from the second fixing groove 121. When the first locking member 32 is connected to the first slider 31, the first locking member 32 and the first slider 31 can clamp the second connecting member 22 and the stop portion 112, so that the second connecting member 22 is connected to the telescopic assembly 12 through the first locking member 32 and the first slider 31, and the first slider 31 will no longer slide relative to the second fixing groove 121, thereby fixing the position of the first slider 31 and the second connecting member 22. After the first locking member 32 and the first slider 31 are disassembled, the first slider 31 can slide relative to the second fixing groove 121, so that the position of the first slider 31, the first locking member 32 and the second connecting member 22 can be adjusted.

[0049] It should be noted that the first locking member 32 is a bolt or screw, and the first slider 31 is a nut, with the first locking member 32 and the first slider 31 being threadedly connected. When the first locking member 32 rotates relative to the first slider 31 in a certain direction until the first locking member 32 and the first slider 31 clamp the connecting assembly and the stop part 112, the connecting assembly is connected to the mounting base 1 through the first locking member 32 and the first slider 31, and the first slider 31 will no longer slide relative to the fixing groove, thus fixing the position of the first slider 31 and the connecting assembly. When the first locking member 32 rotates relative to the first slider 31 in the opposite direction until the first locking member 32 and the first slider 31 no longer clamp the connecting assembly and the stop part 112, the first slider 31 can slide relative to the fixing groove, allowing adjustment of the position of the first slider 31, the first locking member 32, and the connecting assembly.

[0050] Please refer to Figure 4 In some embodiments, the extension direction of the first fixing groove 111 and the extension direction of the second fixing groove 121 are parallel to each other, and the extension direction of the first fixing groove 111 is parallel to the distribution direction of the telescopic component 12 and the extension rod 11.

[0051] With the above settings, the furthest position between the first connector 21 and the second connector 22 can be increased, so that the connecting device can adapt to larger aerial work platforms.

[0052] It should be noted that, in this embodiment, the extending direction of the first fixing groove 111 and the extending direction of the second fixing groove 121 are their length directions, and the length direction of the first fixing groove 111 is parallel to the length direction of the second fixing groove 121. Figure 2 In the X direction, the depth direction of the first fixing groove 111 is parallel to the X direction. Figure 2 In the Y direction, the width direction of the first fixing groove 111 is parallel to... Figure 2 The Z-direction in the middle; the length direction of the second fixing groove 121 is parallel to the Z-direction; Figure 2 In the X direction, the depth direction of the second fixing groove 121 is parallel to the X direction. Figure 2 In the Y direction, the width direction of the second fixing groove 121 is parallel to... Figure 2 The Z direction in the equation.

[0053] Please refer to Figure 3 It should be noted that the shapes of the cavities formed by the first fixing groove 111 and the second fixing groove 121 are adapted to the shape of the first slider 31, so as to fix the position of the first slider 31 in the depth direction of the first fixing groove 111 and the second fixing groove 121, and prevent the first slider 31 from sliding in the depth direction of the first fixing groove 111 and the second fixing groove 121. This facilitates the connection between the first locking fastener 32 and the first slider 31, and also facilitates the clamping of the connecting component and the stop part 112 by the first locking fastener 32 and the first slider 31.

[0054] Please refer to Figure 2 In some embodiments, the mounting base 1 further includes a second locking component 13, which includes a second slider 131 and a second locking member 132. The second slider 131 is slidably disposed in the first fixing groove 111, the telescopic component 12 is disposed at the opening of the first fixing groove 111, and the second locking member 132 passes through the telescopic component 12 and is detachably connected to the second slider 131 to connect the telescopic component 12 and the extension rod 11.

[0055] With the above configuration, the second slider 131 slides within the first fixed groove 111, thereby changing the relative position of the second slider 131 and the extension rod 11. This allows the relative position of the telescopic assembly 12 and the extension rod 11 to change, and the sum of the lengths of the telescopic assembly 12 and the extension rod 11 in the X direction to change, thus adapting to different specifications of aerial work platforms. As a result, the connecting device of this application embodiment can adapt to a variety of different specifications of aerial work platforms.

[0056] It should be noted that the second locking member 132 is a bolt or screw, and the second slider 131 is a nut. The second locking member 132 and the second slider 131 are threadedly connected. When the second locking member 132 rotates relative to the second slider 131 in a certain direction until the second locking member 132 and the second slider 131 clamp the telescopic component 12 and the stop 112, the telescopic component 12 is connected to the extension rod 11 through the second locking member 132 and the second slider 131, and the second slider 131 will no longer slide relative to the first fixing groove 111, thereby fixing the relative positions of the second slider 131, the telescopic component 12, and the extension rod 11. When the second locking member 132 rotates relative to the second slider 131 in the opposite direction until the second locking member 132 and the second slider 131 no longer clamp the telescopic component 12 and the stop 112, the second slider 131 can slide relative to the first fixing groove 111, thereby adjusting the relative positions of the second slider 131, the second locking member 132, the telescopic component 12, and the extension rod 11.

[0057] Please refer to Figure 6 It should be noted that the shape of the cavity formed within the first fixing groove 111 is adapted to the shape of the second slider 131 so as to fix the position of the second slider 131 in the depth direction of the first fixing groove 111 and prevent the second slider 131 from sliding in the depth direction of the first fixing groove 111. This facilitates the connection between the second locking fastener 132 and the second slider 131, and also facilitates the clamping of the telescopic component 12 and the stop part 112 by the second locking fastener 132 and the second slider 131.

[0058] Please refer to Figure 4 and Figure 6In some embodiments, the telescopic assembly 12 includes a mounting plate 122 and a support bar 123. An extension rod 11 is disposed on one side of the support bar 123. The mounting plate 122 is connected to the support bar 123, and the mounting plate 122 covers part of the opening of the first fixing groove 111. The second locking fastener 132 passes through the mounting plate 122 and is detachably connected to the second slider 131. The second fixing groove 121 is formed on the support bar 123.

[0059] With the above configuration, the mounting plate 122 and the support bar 123 form a groove, and the extension rod 11 is disposed in the groove. On the one hand, the groove can limit the position of the extension rod 11, so as to determine the relative position of the extension rod 11 and the telescopic assembly 12 when assembling the extension rod 11 and the telescopic assembly 12. On the other hand, it makes the surface of the extension rod 11 facing the Z direction and the surface of the telescopic assembly 12 facing the Z direction flush, so that both the extension rod 11 and the telescopic assembly 12 can fit against the upper surface of the crossbar on the aerial work platform, so that the connection relationship between the connecting device and the aerial work platform in this embodiment is more stable.

[0060] Please refer to Figure 4 In some embodiments, there are two support bars 123, which are arranged on opposite sides of the extension rod 11, and the mounting plate 122 is mounted on the two support bars 123.

[0061] With the above settings, the relative positions of the extension rod 11 and the telescopic assembly 12 can be better determined when assembling them.

[0062] Furthermore, through the above-mentioned arrangement, two second fixing slots 121 are provided on the telescopic component 12, so that the telescopic component 12 can be connected to the aerial work platform by means of two sets of first locking components 3 and two second connecting members 22, so that the connection relationship between the telescopic component 12 and the aerial work platform is more stable, thereby making the connection relationship between the connection device of this application embodiment and the aerial work platform more stable.

[0063] Please refer to Figure 2 and Figure 3 In some embodiments, the first connector 21 includes a first fixing part 211 and two second fixing parts 212. The first fixing part 211 has a receiving groove, and a portion of the extension rod 11 is received in the receiving groove. The first fixing part 211 covers part of the opening of the first fixing groove 111. The first locking assembly 3 is used to fix the first fixing part 211 to the extension rod 11. The two second fixing parts 212 are located on opposite sides of the extension rod 11, and the two second fixing parts 212 are respectively connected to the first fixing part 211. The second fixing parts 212 are used to connect to the aerial work platform.

[0064] In the above embodiments, both second fixing parts 212 can be connected to the aerial work platform through connecting structural components such as U-bolts and steel wires, making the connection relationship between the first connecting part 21 and the aerial work platform more stable, thereby making the connection relationship between the connecting device of this application embodiment and the aerial work platform more stable.

[0065] In some embodiments, the second fixing part 212 is connected to the aerial work platform by: U-bolts are arranged around the periphery of the crossbar on the fence, and both ends of the U-bolts pass through the through holes on the second fixing part 212 and are threadedly connected to the nuts, so that the second fixing part 212 and the crossbar on the fence are fixed between the U-bolts and the nuts, so that the second fixing part 212 can be connected to the aerial work platform.

[0066] Please refer to Figure 4 In some embodiments, the second connector 22 includes a third fixing part 221 and a fourth fixing part 222. The second fixing part 212 covers part of the opening of the second fixing groove 121. The first locking component 3 fixes the third fixing part 221 to the telescopic component 12. The fourth fixing part 222 is used to connect the aerial work platform.

[0067] In some embodiments, the fourth fixing part 222 is connected to the aerial work platform by: U-bolts are arranged around the periphery of the crossbar on the fence, and both ends of the U-bolts pass through the through holes on the fourth fixing part 222 and are threadedly connected to the nuts, so that the fourth fixing part 222 and the crossbar on the fence are fixed between the U-bolts and the nuts, so that the fourth fixing part 222 can be connected to the aerial work platform.

[0068] Please refer to Figure 7 In some embodiments, the telescopic assembly 12 further includes a telescopic rod 124 and a constant force device 125. The first end of the telescopic rod 124 is used to connect with the cleaning component, and the second end of the telescopic rod 124 is slidably connected to the mounting plate 122 via the constant force device 125. When the telescopic rod 124 moves in the direction from the first end to the second end, the constant force device 125 provides resistance to the telescopic rod 124.

[0069] It should be noted that when the cleaning component connected to the telescopic rod 124 comes close to the wall to be cleaned, a large reaction force is generated instantaneously. Through the above-mentioned design, the telescopic rod 124 is slidably connected to the mounting plate 122 via the constant force device 125, allowing the telescopic rod 124 to move from the first end to the second end under the action of the reaction force, thereby absorbing the reaction force and preventing damage to the cleaning component, telescopic rod 124, and other structures. Furthermore, because the constant force device 125 provides resistance to the telescopic rod 124, it can drive the telescopic rod 124 closer to the wall to be cleaned, forming a balanced state so that the cleaning component remains in close contact with the wall to be cleaned during operation or movement.

[0070] It should be noted that the constant force device 125 can be a constant force spring (commonly known as a "gas spring"). The constant force device 125 can also be other components that can make the telescopic rod 124 extend and retract with constant force, such as a hydraulic spring.

[0071] Please refer to Figure 7 In some embodiments, the telescopic assembly 12 further includes a slide rail 126, a guide rail slider 127, a first fixing member 128, and a second fixing member 129. The slide rail 126 is mounted on the mounting plate 122, the guide rail slider 127 is slidably mounted on the slide rail 126, the first fixing member 128 is mounted on the guide rail slider 127, the telescopic rod 124 is connected to the first fixing member 128, one end of the constant force device 125 is connected to the telescopic rod 124, and the other end of the constant force device 125 is connected to the second fixing member 129. The second fixing member 129 is mounted on the mounting plate 122.

[0072] With the above settings, the slide rail 126 and the guide rail slider 127 cooperate to limit the movement direction of the telescopic rod 124, thereby limiting the position of the telescopic rod 124 and making the telescopic rod 124 move more stably.

[0073] Please refer to Figure 7 In some embodiments, the constant force device 125 is rotatably connected to the second fixing member 129, so that the constant force device 125 can adapt to reaction forces in different directions, which can reduce the risk of the constant force device 125 and the telescopic rod 124 being broken.

[0074] Please refer to Figure 7 In some embodiments, the telescopic assembly 12 further includes a support member 1210, through which the telescopic rod 124 slidably extends.

[0075] With the above configuration, the support member 1210 can support the telescopic rod 124. The support member 1210 and the first fixing member 128 cooperate to stabilize the position of the telescopic rod 124, thereby adjusting the center of gravity of the telescopic rod 124 and making the telescopic rod 124 move more stably.

[0076] Please refer to Figure 7 In some embodiments, the mounting base 1 further includes a protective shell 14, which covers the mounting plate 122 and forms a receiving cavity with the mounting plate 122. The slide rail 126, the guide rail slider 127, the first fixing member 128, the second fixing member 129 and the constant force device 125 are all housed in the receiving cavity, and the telescopic rod 124 slidably passes through the protective shell 14.

[0077] With the above settings, water or dust and other impurities generated when cleaning the wall surface are effectively isolated outside the protective shell 14, ensuring the service life of the telescopic component 12 and a good working environment.

[0078] Please refer to Figure 7 In some embodiments, the mounting base 1 further includes a sealing ring 15 and a baffle 16. The sealing ring 15 is sleeved on the telescopic rod 124 and positioned between the baffle 16 and the protective shell 14, serving to seal the accommodating cavity. Furthermore, the sealing ring 15 is confined between the baffle 16 and the protective shell 14, ensuring that it does not move with the telescopic rod 124 as it moves, thus guaranteeing the structural stability of the telescopic assembly 12.

[0079] Please refer to Figure 7 In some embodiments, a quick-connect connector 4 is provided on the first end of the telescopic rod 124, which is used to connect with the cleaning component. This quick-connect method allows for convenient and quick connection with the cleaning component, saving labor and time costs.
