Based on the embodiments in the embodiments, it is intended to explain the utility model, and cannot be understood as the limitation of the utility model.

[0032] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0033] See appendix Figure 1 One embodiment of this utility model discloses an operation and maintenance device, including a movable first vehicle body 10. The operation and maintenance device further includes a lifting device 20 and an auxiliary trolley assembly 30 disposed on the first vehicle body 10. The lifting device 20 includes a boom assembly 22 and a rotating unit 21. The first end of the boom assembly 22 is used to connect to the object to be transferred. The second end of the boom assembly 22 is rotatably disposed on the first vehicle body 10 through the rotating unit 21. The rotating unit 21 can drive the boom assembly 22 to rotate and rotate the first end of the boom assembly 22 to any position around the first vehicle body 10. The first vehicle body 10 is provided with a trolley storage part for storing the auxiliary trolley assembly 30. The auxiliary trolley assembly 30 is detachably disposed on the trolley storage part. The auxiliary trolley assembly 30 can move independently of the first vehicle body 10 when detached from the first vehicle body 10.

[0034] In this embodiment, when the maintenance equipment is in use, the first vehicle body 10 can be moved to the work area as needed, such as near the liquid-cooled cabinet that needs maintenance. The server can be placed into or taken out of the liquid-cooled cabinet by the boom assembly 22 in the lifting device 20. The maintenance equipment in this embodiment is equipped with a rotating unit 21. When working, the rotating unit 21 can drive the boom assembly 22 to rotate in the circumferential direction, thereby changing the position of the component lifted by the boom assembly 22 in the circumferential direction.

[0035] In addition, in this embodiment, a trolley storage section is provided on the first vehicle body 10. When in use, the trolley storage section can store the auxiliary trolley component 30. The trolley storage section and the auxiliary trolley component 30 are detachably connected, which facilitates the insertion and removal of the auxiliary trolley component 30 into and from the trolley storage section, making assembly and disassembly convenient.

[0036] In this embodiment, the location of the trolley storage part on the first vehicle body 10 is not specifically limited. In actual design, the trolley storage part can be located on the top, side or bottom of the first vehicle body 10.

[0037] In this embodiment, the auxiliary trolley assembly 30 can be detached from the first vehicle body 10 and can move independently. During operation, when the first vehicle body 10 cannot move autonomously, the auxiliary trolley assembly 30 can move in place of the first vehicle body 10 to realize flexible transportation and transfer of server or liquid cooling system components. For example, during the lifting process of the first vehicle body 10 by the lifting device 20, the auxiliary trolley assembly 30 can be removed and used as a transport component. Items taken out of the liquid cooling cabinet by the lifting device 20 can be directly placed on the auxiliary trolley assembly 30.

[0038] As one embodiment of this utility model, see the appendix. Figure 1 , 3 The first vehicle body 10 has a trolley storage section on its bottom side. The trolley storage section includes two storage brackets 11 arranged opposite to each other. Each storage bracket 11 includes a fixing part 111 and a supporting part 113. The fixing part 111 is fixedly connected to the bottom wall of the first vehicle body 10. The supporting part 113 is opposite to and spaced apart from the bottom wall of the first vehicle body 10. The two supporting parts 113 are spaced apart and form a storage space between them and the bottom wall of the first vehicle body 10 to accommodate the auxiliary trolley assembly 30.

[0039] In this embodiment, the trolley storage unit is located on the bottom side of the first vehicle body 10. As shown in the attached figure, the first vehicle body 10 includes a vehicle body and a drive wheel. There is a large gap between the bottom surface of the drive wheel and the bottom surface of the vehicle body. The trolley storage unit is located in the gap between the bottom surface of the drive wheel and the bottom surface of the vehicle body. The auxiliary trolley assembly 30 is placed in the storage space at the bottom of the first vehicle body 10 in a flat position. The way the first vehicle body 10 and the trolley storage unit (auxiliary trolley assembly 30) are distributed vertically in this embodiment can reduce the length and width of the maintenance equipment.

[0040] In this embodiment, there is no specific limitation on the storage method between the trolley storage section and the auxiliary trolley assembly 30. During the design, the auxiliary trolley assembly 30 can be stored in the storage space by snap-fit ​​or plug-in method.

[0041] The fixing part 111 of this utility model is connected to the bottom wall of the first vehicle body 10 by screws. The storage bracket 11 also includes a connecting part 112 connecting the fixing part 111 and the supporting part 113. The fixing part 111 and the supporting part 113 are arranged on opposite sides of the connecting part 112, as shown in the attached figure. Figure 3 , 4As shown, the cross-section of the storage bracket 11 in this embodiment is "Z" shaped. When the storage bracket 11 is connected to the bottom wall of the first vehicle body 10 through the fixing part 111, the fixing part 111 and the first vehicle body 10 form a surface contact, which can increase the bonding area and thus improve the stability of the storage bracket 11. In addition, the support part 113 can also increase the support area of ​​the auxiliary trolley assembly 30, improve the stability of the auxiliary trolley assembly 30 in storage, and also improve the structural strength of the storage bracket 11 itself. In actual installation, the storage bracket 11 can be set as a sheet metal part.

[0042] In this embodiment, the fixing part 111 is connected to the first vehicle body 10 by screws, which makes installation more convenient. Of course, it can also be connected to the first vehicle body 10 by plugging, snapping, welding or other methods.

[0043] In one embodiment of this utility model, the auxiliary trolley assembly 30 includes a second vehicle body 31 and an operating bracket 32. The first end of the operating bracket 32 ​​is rotatably disposed on the second vehicle body 31. The auxiliary trolley assembly 30 includes an unfolded state and a folded state. In the unfolded state, the second end of the operating bracket 32 ​​rotates away from the second vehicle body 31. In the folded state, the second end of the operating bracket 32 ​​rotates to fit against the bearing surface of the second vehicle body 31. In the folded state, the auxiliary trolley assembly 30 is stored in the storage space.

[0044] As attached Figures 5-7 As shown, the auxiliary trolley assembly 30 in this embodiment includes a second vehicle body 31 and an operating bracket 32. Wheels are provided at the bottom of the second vehicle body 31, allowing the auxiliary trolley assembly 30 to be moved manually. In this embodiment, the operating bracket 32 ​​is rotatably connected to the second vehicle body 31. When the auxiliary trolley assembly 30 needs to be moved independently, the operating bracket 32 ​​can be rotated relative to the second vehicle body 31 to the specified position. Figure 6 , 7 As shown in the unfolded state, the second vehicle body 31 can be easily moved by operating the support 32. When the work is completed and the auxiliary trolley assembly 30 needs to be stored, the support 32 can be rotated relative to the second vehicle body 31 to the position shown in the attached diagram. Figure 5 In the folded state shown, the auxiliary trolley assembly 30 is smaller in size, making it easier to store in the trolley storage compartment and reducing the space occupied on the first vehicle body 10.

[0045] It is easy to imagine that, in order to make the auxiliary trolley assembly 30 work better in the unfolded state, a positioning component for positioning the position of the operating support 32 can be set on the operating support 32 or the second vehicle body 31. When the auxiliary trolley assembly 30 is in the unfolded state, the unfolded position of the operating support 32 can be fixed, so that the operating support 32 is more stable when it is pushed by the user.

[0046] In one embodiment of the present invention, a receiving cavity is formed on the first vehicle body 10, the second ends of the rotating unit 21 and the boom assembly 22 are disposed in the receiving cavity, and the first end of the boom assembly 22 extends out of the top of the first vehicle body 10.

[0047] See appendix Figure 1 , 2 3. A portion of the lifting device 20 is housed within a cavity inside the first vehicle body 10. This allows some components of the lifting device 20 to be concealed, reducing user anxiety during use and improving the stability of the lifting device 20 during installation.

[0048] As one embodiment of this utility model, the maintenance equipment further includes a control component disposed on the first vehicle body 10. The control component includes an electronic control module and a mechanical handle 15. The accommodating cavity is divided into a first cavity and a second cavity distributed front and rear. The second ends of the rotating unit 21 and the boom assembly 22 are disposed in the first cavity. The electronic control module is disposed in the second cavity and electrically connected to the drive wheel of the first vehicle body 10. One end of the mechanical handle 15 is disposed in the first cavity, and the other end of the mechanical handle 15 extends out of the top of the first vehicle body 10 for operation by the operator.

[0049] In this embodiment, the installation positions of the lifting device 20 and the control components are divided into zones, making the distinction between each component clearer.

[0050] As one embodiment of this utility model, see the appendix. Figure 1 The first vehicle body 10 has a first inspection port communicating with the first cavity and a second inspection port communicating with the second cavity on its side wall. The first vehicle body 10 includes a first inspection door 12 corresponding to the first inspection port and a second inspection door 13 corresponding to the second inspection port. The first inspection door 12 is used to open or close the first inspection port, and the second inspection door 13 is used to open or close the second inspection port.

[0051] In this embodiment, the first cavity and the second cavity are respectively provided with maintenance ports. In this way, when the lifting device 20 and the control component malfunction, the corresponding first maintenance door 12 and second maintenance door 13 can be opened for maintenance, making the maintenance of the equipment more convenient.

[0052] To facilitate the maintenance of the control components, in one embodiment of the present invention, the top of the first vehicle body 10 is provided with a top maintenance port communicating with the second cavity. The first vehicle body 10 includes a top maintenance door 14 corresponding to the top maintenance port, and the top maintenance door 14 is used to open or close the top maintenance port.

[0053] In one embodiment of this utility model, a shelf 16 is provided inside the first cavity. During use, remote controls, chargers, and other components can be placed on the shelf 16 to prevent loss.

[0054] The first inspection door 12, the second inspection door 13, and the top inspection door 14 in this utility model can be configured to slide or rotate, as shown in the attached diagram. Figure 1 , 3 As shown, the inspection door structure in this utility model is configured to open and close by rotation.

[0055] In one embodiment of the present invention, the boom assembly 22 includes a support arm 221, a swing arm 222, and a swing arm 222 drive unit. The first end of the support arm 221 is mounted on the first vehicle body 10 via the rotating unit 21. The second end of the swing arm 222 is used to connect to the object to be transported. The swing arm 222 drive unit can drive the swing arm 222 to rotate around the pivot fixing part 111 of the swing arm 222 and the support arm 221, so that the second end of the swing arm 222 is raised and lowered.

[0056] In this embodiment, the swing arm 222 of the boom assembly 22 can be driven to rotate by the swing arm 222 drive unit, which can drive the second end of the swing arm 222 to rise and fall, thereby adjusting the height of the lifted object and making it convenient to put the object into or take it out of the liquid cooling cabinet.

[0057] In this embodiment, the swing arm 222 drive unit can be an electric actuator or a cylinder, as shown in the attached figure. Figure 1 As shown, one end of the electric actuator or cylinder is fixed to the support arm 221, and one end of the telescopic rod is rotatably connected to the swing arm 222. In this way, when the telescopic rod extends or retracts, it can drive the swing arm 222 to rotate in the vertical plane, thereby changing the height of the second end of the swing arm 222.

[0058] As one embodiment of this utility model, see the appendix. Figure 1The swing arm 222 includes a swing arm 222 body, a sliding table 2222, a winch assembly 2223, and a gripping assembly (not shown in the figure). The sliding table 2222 is slidably disposed on the swing arm 222 body along the length direction of the swing arm 222 body. The sliding table 2222 can be driven by a sliding drive unit 224, which can be an electric actuator or a cylinder, etc. The winch assembly 2223 is fixed on the swing arm 222 body, and the rope in the winch assembly 2223 passes around the free end of the sliding table 2222 and is connected to the gripping assembly.

[0059] In this embodiment, the boom assembly 22 fixes the gripping component to the server to be transported, and then the winch assembly 2223 winds the rope to lift the server. With the structure of the swing arm 222 swinging in the vertical plane, the lifting height of the server can be better controlled. Moreover, the setting of the sliding table 2222 can increase the length of the swing arm 222, which is suitable for lifting servers in different positions in the liquid-cooled cabinet. For example, when lifting a server near the edge of the liquid-cooled cabinet, the length of the swing arm 222 can be reduced, and when lifting a server in the center of the liquid-cooled cabinet, the length of the swing arm 222 can be increased.
