[0060] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0061] like Figures 1 to 7 As shown, the first embodiment of the present invention provides a transport trolley, which includes a first mounting plate 1, a second mounting plate 2 and a sliding structure 3. The first mounting plate 1 and the second mounting plate 2 are both used to mount electrical components; the first mounting plate 1 is located above the second mounting plate 2, and the first mounting plate 1 and the second mounting plate 2 can be synchronously and movably arranged to move to an unfolded position where the first mounting plate 1 and the second mounting plate 2 are mutually displaced or to a folded position where the first mounting plate 1 and the second mounting plate 2 are relative to each other. The sliding structure 3 is arranged on one side of the first mounting plate 1; the sliding structure 3 includes a sliding member 31 and a main body 32, both of which are extended along the extension direction of the first mounting plate 1, and the main body 32 and the sliding member 31 are respectively provided with a first wire groove and a second wire groove for accommodating the power cord, and the sliding member 31 is provided with a fixing portion for fixing the power cord; the sliding member 31 is movably arranged on the main body 32 along the extension direction of the main body 32, so as to move to an open position in which at least a part of the sliding member 31 extends out of one side of the main body 32 or a folded position in which at least a part of the sliding member 31 is opposite to the main body 32. Among them, one of the first mounting plate 1 and the second mounting plate 2 is connected to the sliding member 31, so that the sliding member 31 is in an open position when one of the first mounting plate 1 and the second mounting plate 2 moves to an extended position, and the sliding member 31 is in a folded position when one of the first mounting plate 1 and the second mounting plate 2 moves to a folded position.

[0062] The transport trolley provided by the first embodiment of the present invention firstly improves the installation and maintenance efficiency of electrical components. Through the synchronous activity design of the first mounting plate 1 and the second mounting plate 2, the electrical components can be quickly deployed or folded, thereby realizing the rapid installation and maintenance of the electrical components without disassembling the housing of the transport trolley, greatly saving time and labor costs, and improving the maintenance efficiency and availability of the equipment. Secondly, the management and protection of the power cord are optimized. The sliding structure 3 is designed with a sliding member 31 and a main member 32, both of which are provided with a wire groove inside, which can effectively manage and protect the power cord. During the process of the installation plate being deployed or folded, the sliding member 31 can move in coordination to drive the extension or retraction of the power cord in the wire groove, thereby avoiding the power cord from being stretched, squeezed or worn during the process of the installation plate being deployed or folded, and ensuring the stability and safety of the electrical connection. In addition, through the deployment or folding of the first mounting plate 1 and the second mounting plate 2, the installation positions of the electrical components can be increased on the basis of reducing the space occupied by the transport trolley, thereby facilitating the layout of the electrical components and improving the space utilization efficiency of the transport trolley. Therefore, the transport trolley provided in this embodiment can solve the technical problem of low inspection and maintenance efficiency of AGV trolleys in the prior art.

[0063] Specifically, the transport trolley is an AGV trolley. The power cord is used to connect to a power source.

[0064] Specifically, when the sliding member 31 is in the folded position, at least a portion of the sliding member 31 is embedded in the first wire groove. The first wire groove and the second wire groove are interconnected. This design ensures that when in the folded position, the power cord can be safely and orderly stored in the first wire groove and the second wire groove, avoiding the disorder of the cables and the potential risk of electrical short circuit. At the same time, through the connection between the first wire groove and the second wire groove, it is ensured that the power cord can be smoothly unfolded during the movement of the sliding member 31 from the folded position to the open position, avoiding the twisting and damage of the cable during the movement, and improving the service life of the power cord and the reliability of the electrical system.

[0065] Specifically, along the direction from the first mounting plate 1 to the second mounting plate 2, the spacing between the first mounting plate 1 and the second mounting plate 2 is greater than the maximum height of the electrical component. This design ensures that during the installation or maintenance of the electrical component, the movement of the mounting plate will not be disturbed by the internal structure of the electrical component or the transport vehicle, and provides sufficient operating space. At the same time, since there is enough clearance between the first mounting plate 1 and the second mounting plate 2, it is beneficial to the heat dissipation of the electrical component, reducing the risk of damage to the electrical component due to overheating, thereby improving the stability of the electrical system and extending the service life of the electrical component.

[0066] Specifically, the transport trolley also includes a drive assembly 4, which includes a first drive member 41 and a second drive member 42 that are mutually driven and connected, and the second drive member 42 has a first drive end 421 and a second drive end 422, and the first drive end 421 and the second drive end 422 are synchronously arranged in opposite directions; the first drive end 421 is driven and connected to the first mounting plate 1, and the second drive end 422 is driven and connected to the second mounting plate 2. With such a structural setting, through the setting of the drive assembly 4, the movement of the first mounting plate 1 and the second mounting plate 2 can be accurately and synchronously controlled, and the rapid expansion and folding of the mounting plates can be achieved, which provides efficient support for the installation and maintenance of electrical components. At the same time, the mutual driving design of the first drive member 41 and the second drive member 42 ensures the stability and synchronization of the first mounting plate 1 and the second mounting plate 2 during the movement process, avoids the jamming or damage of the mounting plates caused by uneven driving, and improves the stability and durability of the system. In addition, this drive design also simplifies the control logic of the transport trolley, makes the overall operation more convenient, and improves the degree of automation and the intelligence level of the system.

[0067] Specifically, the first driving member 41 is a driving roller, and the second driving member 42 is a driving chain, and the driving chain is wound around at least a portion of the driving roller. With such a structural arrangement, a combination of a driving roller and a driving chain can achieve accurate and stable power transmission, ensuring the precise synchronous movement of the first mounting plate 1 and the second mounting plate 2. The rotation of the roller drives the chain, and the linear movement of the chain is converted into the translation of the mounting plate. This transmission method is highly flexible, simple to maintain, and can withstand a large load, thereby improving the reliability and efficiency of the electrical component installation mechanism. At the same time, at least a portion of the driving roller is wound around by the driving chain, ensuring close contact between the chain and the roller, reducing energy loss during power transmission, and improving the efficiency of power transmission. Specifically, a gear is provided on the driving roller, and the gear is rotatably arranged to drive the driving chain to rotate.

[0068] Specifically, the first drive end 421 is located above the second drive end 422, and the vertical spacing between the first drive end 421 and the second drive end 422 is adjustable. With such a structural setting, by adjusting the vertical spacing between the first drive end 421 and the second drive end 422, electrical components of different heights can be accommodated, ensuring the stability and safety of the electrical components during installation or maintenance. This adjustable design improves the adaptability and flexibility of the system, allowing the same electrical component installation mechanism to meet the installation requirements of electrical components of different sizes, reducing changes to the internal structure of the transport trolley and reducing customization costs.

[0069] Specifically, there are at least two first driving members 41, and at least two first driving members 41 are arranged at intervals along the extension direction of the first mounting plate 1, and the distance between one of the at least two first driving members 41 and the other in the extension direction of the first mounting plate 1 can be adjusted. With such a structural arrangement, the use of at least two first driving members 41 can not only disperse the load, reduce the wear of a single first driving member 41, and extend the service life of the first driving member 41 and the second driving member 42, but also improve the smoothness and synchronization of the movement of the first mounting plate 1 and the second mounting plate 2, and ensure the safety of the electrical components during the movement. In addition, by arranging the first driving members 41 with adjustable spacing in the extension direction of the first mounting plate 1, the position of the first driving member 41 can be adjusted according to the layout of the electrical components on the mounting plate to meet the installation requirements of different electrical components, thereby improving the flexibility and efficiency of the installation of electrical components of the transport trolley.

[0070] In this embodiment, the transport trolley further comprises a mounting structure 5, which is arranged on one side of the first mounting plate 1. The mounting structure 5 comprises a first side plate 51 and a second side plate 52 which are connected to each other and arranged perpendicularly to each other. The first side plate 51 is arranged parallel to the first mounting plate 1, and the sliding structure 3 is arranged on the first side plate 51; the second driving member 42 is arranged opposite to the second side plate 52, and the first driving member 41 is connected to the second side plate 52. With such a structural arrangement, the design of the mounting structure 5 not only provides a stable mounting platform for the sliding structure 3, but also enhances the structural stability and rigidity of the overall mechanism through the vertical connection between the first side plate 51 and the second side plate 52, thereby avoiding the influence of vibration on the electrical components during transportation. At the same time, the first driving member 41 is connected to the second side plate 52, thereby enhancing the stability of the structure, making the unfolding and folding process of the first mounting plate 1 and the second mounting plate 2 smoother, reducing the potential damage to the electrical components, and ensuring the stability and safety of the transport trolley in various working environments.

[0071] Specifically, the mounting structure 5 includes a mounting member 53, and there are at least two mounting members 53, one of the at least two mounting members 53 is arranged on one side of the first mounting plate 1, and the other is arranged on the other side of the first mounting plate 1. The mounting member 53 is extended along the extension direction of the first mounting plate 1. The first driving member 41 is connected to the mounting member 53, and the mounting member 53 is arranged on the second side plate 52. The design of at least two mounting members 53 can distribute the load more evenly and improve the load-bearing capacity and stability of the entire structure. The mounting member 53 extends along the extension direction of the first mounting plate 1, ensuring stability and reliability during the driving process. At the same time, this design makes the driving of the first mounting plate 1 more uniform, avoids deformation of the plate or damage to the driving member due to local uneven force, and extends the service life of the electrical component mounting mechanism.

[0072] Specifically, the mounting member 53 is an aluminum profile. Thus, the aluminum profile used as the mounting member 53 not only has good strength and rigidity, and can withstand various forces during the operation and maintenance of the transport trolley, but also the lightweight characteristics of the aluminum profile help to reduce the overall weight of the transport trolley and improve its operating efficiency and flexibility.

[0073] Specifically, the first mounting plate 1 includes a first main plate member 11 and a first connecting plate member 12 that are connected to each other. The first connecting plate member 12 is located on one side of the first main plate member 11. The first connecting plate member 12 is provided with a first connecting portion 121 for fixedly connecting to the first driving end 421; wherein, there are at least two first connecting plate members 12, and at least two first connecting plate members 12 are arranged at intervals along the extension direction of the first mounting plate 1. With such a structural arrangement, the connection strength and structural stability of the first mounting plate 1 are increased. In particular, by arranging a plurality of first connecting plate members 12, the force of connecting to the first driving end 421 can be more evenly distributed, thereby avoiding deformation or damage caused by excessive local force. At the same time, the first connecting plate members 12 arranged at intervals provide a more flexible connection method with the driving assembly 4, which is convenient for adjustment according to actual needs, thereby improving the adaptability and maintainability of the mounting plate.

[0074] Specifically, the second mounting plate 2 includes a second main plate member and a second connecting plate member that are connected to each other. The second connecting plate member is located on one side of the second main plate member. The second connecting plate member is provided with a second connecting portion for fixedly connecting with the second driving end 422. There are at least two second connecting plates, and at least two second connecting plates are arranged at intervals along the extension direction of the second mounting plate 2. Such a structural arrangement improves the stability and strength of the connection. The interval arrangement of the second connecting plates also ensures the uniform distribution of force, avoids structural problems caused by local force, and enhances the adaptability and adjustability of the second mounting plate 2, facilitates the connection with the second driving end 422, and ensures the smoothness and reliability during the driving process.

[0075] Specifically, the second driving member 42 is provided with a third connecting portion 401, the third connecting portion 401 is located on the side of the second driving member 42 close to the first mounting plate 1, and the third connecting portion 401 includes at least two third connecting plates, and the at least two third connecting plates are arranged at intervals along the extension direction of the first mounting plate 1. The first connecting plate 12 is used to be connected with the third connecting plate by bolts. The second connecting plate is used to be connected with the third connecting plate by bolts. In this way, by arranging the third connecting portion 401 on the second driving member 42, including at least two third connecting plates arranged at intervals along the extension direction of the first mounting plate 1, this design ensures the stability and uniformity of the connection with the first connecting plate 12 and the second connecting plate. The bolt connection method makes the entire connection structure both stable and easy to disassemble and maintain, thereby improving the maintainability and flexibility of the system. At the same time, this connection method can adapt to electrical components of different sizes, so that when the electrical components are installed and repaired, the first mounting plate 1 and the second mounting plate 2 can be more flexibly unfolded and retracted, thereby ensuring the efficiency and safety of the electrical components during installation.

[0076] In this embodiment, the sliding member 31 is provided with a guide groove 311 extending along the extension direction of the sliding member 31, and a guide protrusion 321 is provided on one side of the main member 32. The guide protrusion 321 is located in the guide groove 311 and cooperates with the guide groove 311. Such a structural arrangement ensures the stability and guidance of the sliding member 31 during the sliding process, avoids the lateral deviation and shaking of the sliding member 31 during the movement, and improves the stability and reliability of the sliding structure 3. The guiding cooperation between the guide groove 311 and the guide protrusion 321 enables the sliding member 31 to move between the open and folded positions accurately, ensures the smooth unfolding and orderly folding of the power cord when the sliding member 31 moves, avoids damage to the power cord, and prolongs its service life.

[0077] Specifically, the sliding member 31 and the main member 32 are both U-shaped structures. In this way, the depth of the wire groove can be effectively increased, providing a safer accommodation space for the power cord. At the same time, the design of the U-shaped structure increases the contact area between the sliding member 31 and the main member 32, and improves the stability during the sliding process. In addition, the U-shaped structure can provide better rigidity, reduce deformation when bearing load, ensure the structural stability and durability of the sliding member 31 and the main member 32 under long-term use, and is suitable for frequent movement and high-load working environments.

[0078] Specifically, the transport trolley further comprises a support structure, which is arranged on a side of the first mounting plate 1 close to the second mounting plate 2, and the support structure is movably arranged so as to move to a supporting state where the support structure and the first mounting plate 1 are arranged at a preset angle when the first mounting plate 1 is in the unfolded position, or to a retracted state where the support structure and the first mounting plate 1 are attached to each other when the first mounting plate 1 is in the folded position. This movable support structure design can provide additional support for the first mounting plate 1 in the unfolded position, ensuring that the first mounting plate 1 can remain stable when installing or repairing electrical components, avoiding shaking or tilting due to gravity or external forces, and improving the safety and efficiency of the installation and repair of electrical components. When the first mounting plate 1 is in the folded position, the support structure can be automatically retracted and attached to the first mounting plate 1, reducing space occupation, avoiding interference of the support structure with the external environment, and improving the flexibility and adaptability of the transport trolley. In addition, the automatic adjustment mechanism of the support structure simplifies the operation process, improves the degree of automation and user experience.

[0079] Specifically, the fixed part includes a movable part and a limiting part connected to each other, and the movable part can be movably arranged so that when the sliding member 31 moves along the extension direction of the main body 32, at least part of the limiting part can enclose a limiting space adapted to the power cord. With such a structural arrangement, the limiting space of the power cord can be dynamically adjusted according to the movement of the sliding member 31, ensuring that a part of the power cord can be limited in the limiting space during the movement of the sliding member 31, thereby facilitating the unfolding of the power cord that is gathered together in the wire trough during the movement of the sliding member 31.

[0080] It should be noted that “at least part of the limiting member encloses a limiting space adapted to the power cord” means that the inner diameter of the limiting space is consistent with the outer diameter of the power cord.

[0081] In the second embodiment, an adsorption part is provided on the power cord, and the fixed part is an adsorption member, and the adsorption member is used to be adsorbed with the adsorption part, so that when the sliding member 31 moves along the extension direction of the main body 32, the adsorption member and the adsorption part are adsorbed and fixed to each other. In this way, the power cord can be automatically adsorbed and fixed at the set position when the sliding member 31 moves, ensuring that a part of the power cord can be adsorbed in the sliding member 31 during the movement of the sliding member 31, and then facilitating the unfolding of the power cord that is gathered together in the wire trough during the movement of the sliding member 31. At the same time, the adsorption and fixing method of the adsorption member and the adsorption part avoids the damage to the power cord that may be caused to the power cord by traditional fixing methods (such as binding or buckling), ensuring the integrity and stability of the power cord, thereby improving the overall performance and safety of the electrical system.

[0082] In the first embodiment, the transport trolley further comprises a first resistance detection member and a controller. The first resistance detection member is arranged on the sliding member 31 and is used to detect the moving resistance of the sliding member 31. The first resistance detection member and one of the first mounting plate 1 and the second mounting plate 2 are connected to the controller. The controller is used to make one of the first mounting plate 1 and the second mounting plate 2 in a stationary state when the first resistance detection member detects that the change rate of the moving resistance of the sliding member 31 is greater than the first preset value. With such a structural setting, the moving resistance of the sliding member 31 can be monitored in real time, and when the resistance increases abnormally, the first mounting plate 1 and the second mounting plate 2 are automatically controlled to stop moving, thereby preventing the sliding member 31 from being damaged due to external resistance or internal failure, avoiding the possibility of the power cord being stuck and torn off, and ensuring the safety of electrical components and the stability of the electrical system. Through automated monitoring and control, the intelligence level of the system is improved, operational errors and maintenance costs are reduced, and the adaptability and safety of the transport trolley in complex environments are enhanced.

[0083] In the first embodiment, the transport trolley further includes a second resistance detection member and a controller. The second resistance detection member is disposed on one of the first drive end 421 and the second drive end 422 and is used to detect the movement resistance of one of the first drive end 421 and the second drive end 422. The second resistance detection member and one of the first drive end 421 and the second drive end 422 are connected to the controller. The controller is used to stop one of the first drive end 421 and the second drive end 422 when the second resistance detection member detects that the change rate of the movement resistance of one of the first drive end 421 and the second drive end 422 is greater than a second preset value. In this way, by introducing the second resistance detection member, the change of resistance encountered by the first drive end 421 or the second drive end 422 when moving can be detected. Once the change rate of resistance exceeds the preset value, the controller will automatically stop the movement of the drive end. This mechanism can prevent the drive end from overloading when encountering obstacles, avoid damage to the drive system and related mechanical components (such as chains, rollers, etc.), improve the reliability and safety of the electrical component installation mechanism, and also reduce the risk of damage to the electrical components caused by overload.

[0084] In the first embodiment, the transport trolley further includes a controller, and the transport trolley further includes a first weight detection member, which is arranged on the first mounting plate 1 and is used to detect the total weight of the first mounting plate 1 and the electrical components arranged on the first mounting plate 1; the first weight detection member and the first driving member 41 are both connected to the controller, and the controller is used to put the first driving member 41 in a resting state when the first weight detection member detects that the total weight of the first mounting plate 1 and the electrical components arranged on the first mounting plate 1 is greater than the preset weight. With such a structural setting, the total weight of the electrical components on the mounting plate can be detected in real time. Once the weight exceeds the preset safety limit, the controller will automatically stop the operation of the first driving member 41, preventing the drive system from malfunctioning and the electrical components from being damaged due to overloading, and ensuring the safe operation of the electrical component installation mechanism and the stability of the electrical system. This combination of weight detection and automatic control improves the intelligence level and safety of the system and reduces maintenance costs.

[0085] Specifically, the transport trolley also includes a second weight detection member, which is arranged on the second mounting plate 2 and is used to detect the total weight of the second mounting plate 2 and the electrical components arranged on the second mounting plate 2; the second weight detection member and the first drive member 41 are both connected to the controller, and the controller is used to put the first drive member 41 into a rest state when the second weight detection member detects that the total weight of the second mounting plate 2 and the electrical components arranged on the second mounting plate 2 is greater than the preset weight. With such a structural setting, the total weight of the electrical components on the mounting plate can be detected in real time. Once the weight exceeds the preset safety limit, the controller will automatically stop the operation of the first drive member 41, preventing the drive system from malfunctioning and damaging the electrical components due to overloading, and ensuring the safe operation of the electrical component installation mechanism and the stability of the electrical system. This combination of weight detection and automatic control improves the intelligence level and safety of the system and reduces maintenance costs.

[0086] It should be noted that “the total weight of the first mounting board 1 and the electrical components arranged on the first mounting board 1” refers to the sum of the weight of the first mounting board 1 and the weight of the electrical components arranged on the first mounting board 1. “The total weight of the second mounting board 2 and the electrical components arranged on the second mounting board 2” refers to the sum of the weight of the second mounting board 2 and the weight of the electrical components arranged on the second mounting board 2.

[0087] It should be noted that when the first driving member 41 is in the rest state, the driving end of the first driving member 41 stops moving.
