Description

Technical Field

[0001] This utility model relates to the technical field of ship rust removal equipment, and in particular to a charging device for a dock rust removal vehicle. Background Technology

[0002] Rust removal in the dry dock is a crucial step in ship repair. During this process, rust removal trucks using ultra-high pressure water are a common method for solving rust removal problems. The application of these rust removal trucks not only significantly improves the efficiency of dry dock rust removal operations and effectively reduces the labor intensity and safety risks for operators, but also enables the comprehensive recycling and closed-loop treatment of highly polluting rust-containing wastewater generated during the rust removal process.

[0003] Currently, the power sources for dockside rust removal vehicles are mainly fuel or electricity, with the latter being more in line with the concept of green and environmentally friendly construction and having higher application prospects. However, since the working area of ​​the dockside rust removal vehicle is the dock bottom, it is impossible to install charging power supply devices there. That is, the charging device can only be set up outside the dock bottom, and the rust removal vehicle can only travel back and forth between the charging device and the working area to ensure its range, which affects the overall work efficiency.

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0032] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0033] The charging device for the dock bottom rust removal vehicle provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0034] This application provides a charging device for a dockside rust removal vehicle, such as... Figures 1 to 3 As shown, it includes a mounting frame, a take-up reel 300 rotatably mounted on the mounting frame, an electric wire 220 wound on the take-up reel 300, and a guide assembly.

[0035] One end of the wire 220 is connected to the electrical box 210, and the other end is wound out of the take-up reel 300 and fixedly connected to the plug 230. The guide assembly is used to guide the wire 220 that has wound out of the take-up reel 300.

[0036] Understandably, the mounting frame is fixedly set on the outside of the dock bottom. By rotating the take-up reel 300, one end of the wire 220 of the connector 230 can be taken in and out, thereby adjusting the length of the wire 220 so that the connector 230 can be electrically connected to the rust removal vehicle at the dock bottom, realizing long-distance power supply to the rust removal vehicle at the dock bottom.

[0037] In this embodiment, the charging device of the dock bottom rust removal vehicle described above is used. The winding and unwinding of the wire 220 is achieved by rotating the winding wheel 300. At the same time, the wire 220 is guided by the guiding component, thereby adjusting the positional relationship between the plug 230 and the dock bottom rust removal vehicle. This enables long-distance power supply to the dock bottom rust removal vehicle, allowing it to perform long-term operations at the dock bottom. This avoids the reduction in rust removal efficiency caused by repeated charging, greatly improving the practicality of the dock bottom rust removal vehicle.

[0038] In a preferred embodiment, the guide assembly includes a longitudinal guide rod (not shown in the figure) rotatably mounted on the mounting frame with its axis of rotation extending longitudinally.

[0039] Understandably, the wire 220 wound from the take-up reel 300 can further bypass the longitudinal guide rod, thereby limiting and guiding the wire 220.

[0040] In a preferred embodiment, two parallel longitudinal guide rods are arranged at intervals on the mounting frame.

[0041] The wire 220, which is wound from the take-up reel 300, passes between the two longitudinal guide rods.

[0042] Understandably, the two longitudinal guide rods can limit the movement of the wire 220, thereby preventing the wire 220 from wobbling relative to the mounting frame due to excessive extension.

[0043] In a preferred embodiment, the guide assembly further includes a transverse guide rod (not shown in the figure) rotatably mounted on the mounting frame with its axis of rotation extending laterally.

[0044] Understandably, the wire 220 wound from the take-up reel 300 can further bypass the cross guide rod, thereby limiting and guiding the wire 220.

[0045] In a preferred embodiment, two parallel crossbars are arranged at intervals on the mounting frame.

[0046] The wire 220, which is wound from the take-up reel 300, passes between the two horizontal guide rods.

[0047] Understandably, by using two longitudinal guide rods and two transverse guide rods, the wire 220 that has come off the take-up reel 300 can be confined within a closed rectangular space, that is, the displacement of the wire 220 in the non-extending direction is restricted, further reducing the swaying of the wire 220 relative to the mounting frame after it is released.

[0048] In a preferred embodiment, such as Figures 1 to 3 As shown, a telescopic device is also provided on the mounting frame. The fixed end of the telescopic device is fixedly set on the mounting frame, and the telescopic end extends away from the take-up reel 300.

[0049] The guide assembly also includes a connector 710 disposed on the telescopic end of the telescopic device, and a pulley 720 rotatably disposed on the connector 710.

[0050] Among them, the wire 220 wound from the take-up reel 300 can be further bypassed by the top of the pulley 720, thereby guiding the wire 220.

[0051] Understandably, the distance between the pulley 720 and the take-up reel 300 can be adjusted by the telescopic device, that is, the distance between the wire 220 after passing around the pulley 720 and the take-up reel 300 can be adjusted.

[0052] It should be noted that when the charging device is installed outside the dock bottom, the wire 220 that goes around the pulley 720 will hang down to the dock bottom. The distance between the hanging wire 220 and the hull or dock wall can be adjusted by the telescopic device, thereby preventing the wire 220 from interfering with the position when hanging down and affecting the power supply to the dock bottom rust removal vehicle.

[0053] In a preferred embodiment, such as Figures 1 to 3 As shown, the telescopic device includes a fixed cylinder 610 fixedly mounted on the mounting frame and a telescopic arm 620 slidably connected to the fixed cylinder 610. The connecting piece 710 is connected to the end of the telescopic arm 620 away from the take-up reel 300.

[0054] The fixed cylinder 610 is provided with a first insertion hole, and the telescopic arm 620 is provided with a plurality of second insertion holes arranged along the axial direction. When a limiting pin is inserted into the first insertion hole of the fixed cylinder 610 and the limiting pin is connected to the corresponding second insertion hole on the telescopic arm 620, the relative position between the fixed cylinder 610 and the telescopic arm 620 is restricted.

[0055] It is understandable that the telescopic device is not limited to the above-mentioned form. For example, it can also be set as an electric telescopic rod, a cylinder, a hydraulic cylinder, or other telescopic structures, as long as it can realize the distance adjustment between the pulley 720 and the take-up reel 300. This will not be elaborated here.

[0056] In a preferred embodiment, a sensing component is also included for monitoring the extension and retraction status of the wire 220.

[0057] In a preferred embodiment, such as Figure 2 As shown, the sensing component includes a locking element 810, a collar 820, a traction chain 830, and a tension sensor 840.

[0058] The locking element 810 is detachably and fixedly mounted on the wire 220. The collar 820 is sleeved on the wire 220 and located on the side of the locking element 810 near the take-up reel 300. The tension sensor 840 is fixedly mounted on the telescopic end of the telescopic device. The traction chain 830 is fixedly mounted between the sensing end of the tension sensor 840 and the collar 820.

[0059] Understandably, when the cable 220 is extended and the locking member 810 is located on the side of the collar 820 away from the take-up reel 300 and not in contact with the collar 820, the traction chain 830 naturally hangs down under the gravity of the collar 820, thereby pulling the sensing end of the tension sensor 840. At this time, the sensing component can determine that the cable 220 is in the extended state. When the cable 220 is retracted, the locking member 810 comes into contact with the collar 820 as the cable 220 retracts. The gravity of the collar 820 cancels out the pushing force of the locking member 810. At this time, the gravity on the traction chain 830 decreases, and the sensing end of the tension sensor 840 can obtain the change in the tension of the traction chain 830, thereby determining that the cable 220 is in the retracted state. To prevent the cable 220 from being over-retracted, when the sensing component detects that the cable 220 has reached the retracted position, it can send a locking signal to the staff or control system, thereby stopping the rotation of the take-up reel 300, that is, stopping the continued retraction of the cable 220, and ensuring the safety of the charging device.

[0060] In a preferred embodiment, the sensing component further includes a position sensor mounted on the take-up reel 300, which is used to monitor the take-up and untake-up status of the wire 220 closest to the rotation axis of the take-up reel 300.

[0061] Understandably, when the position sensor detects that the wire 220 closest to the rotation axis of the take-up reel 300 is in the extended state, it can be determined that all the wire 220 on the take-up reel 300 has been extended. At this time, a locking signal needs to be sent to the staff or control system to stop the rotation of the take-up reel 300, that is, to stop the continued extension of the wire 220, thus ensuring the safety of the charging device.

[0062] In a preferred embodiment, such as Figures 1 to 3 As shown, it also includes a power unit 400 for driving the take-up reel 300 to rotate.

[0063] In a preferred embodiment, such as Figures 1 to 3 As shown, the power unit 400 includes a drive motor that is fixedly mounted on the mounting frame and is poweredly connected to the take-up reel 300.

[0064] It is understandable that the rotation drive of the take-up reel 300 is not limited to the one mentioned above. For example, the take-up reel 300 can also be driven by manual means, as long as the wire 220 can be taken in and out. This will not be elaborated here.

[0065] In a preferred embodiment, such as Figures 1 to 3 As shown, the mounting frame includes a mounting frame 110 and a support bracket 120 fixedly mounted on the mounting frame 110.

[0066] The electrical box 210 is fixedly mounted on the mounting frame 110, the power unit 400 is fixedly mounted on the bearing bracket 120, and the take-up reel 300 is rotatably mounted on the bearing bracket 120.

[0067] In a preferred embodiment, such as Figure 3 As shown, a slip ring device 900 is provided between the electrical box 210 and the take-up reel 300, and the end of the wire 220 away from the electrical box 210 is wound around the take-up reel 300 through the slip ring device 900.

[0068] Understandably, the slip ring device 900 ensures that the winding and unwinding of the wire 220 on the take-up reel 300 does not affect the connection between the wire 220 and the electrical box 210, thereby guaranteeing the working stability of the charging device.

[0069] In a preferred embodiment, such as Figure 3 As shown, a positioning socket 240 that can be plugged into the plug 230 is fixed on the protective frame of the slip ring device 900.

[0070] It is understandable that the positioning socket 240 is not limited to the above-mentioned form. For example, it can also be set on the mounting frame, as long as it can achieve the positioning of the plug 230 in the non-working state. This will not be elaborated here.

[0071] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, it should be noted that the scope of the methods and apparatuses in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved.
