Description

Technical Field

[0001] This utility model belongs to the field of marine battery swapping trolley technology, and more specifically, relates to a chain-type marine battery swapping trolley system. Background Technology

[0002] On electric ships, traditional battery swapping trolleys typically employ a rack and pinion drive mechanism, coupled with servo motor control, to achieve relatively precise movement. However, racks are difficult and expensive to manufacture, and the long rack lengths further increase the overall cost of the battery swapping trolley. Using other drive methods, such as roller-based systems, makes it difficult to guarantee operational accuracy. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a chain-type marine battery swapping trolley system. This system solves the problems of high cost associated with the gear and rack drive mechanism used in existing marine battery swapping trolleys, and the difficulty in ensuring operational accuracy with other battery swapping trolley driving methods.

[0004] To achieve the above objectives, this utility model provides a chain-type marine battery swapping trolley system, comprising:

[0005] The track, one end of which is fixed inside the battery compartment, and the other end of which can extend outside the battery compartment to form an extension section;

[0006] The battery swapping trolley includes a frame and a chain-driven mechanism. The frame includes four legs, and the lower end of each leg is provided with a moving part that cooperates with the track. The frame is used to house a lifting and lowering mechanism for lifting and lowering the battery hoist. The chain-driven mechanism includes a ring chain and a chain drive assembly. The frame is connected to the ring chain through a connecting part.

[0007] The positioning mechanism includes a through-beam sensor, a telescopic component, and a first micro switch. The through-beam sensor is connected to the telescopic component, and the first micro switch is connected to the chain drive assembly. The through-beam sensor and the telescopic component are spaced apart on the inner wall of the battery compartment. The first micro switch is located on the side of the telescopic end of the telescopic component and is used to cooperate with the support leg.

[0008] Optionally, the positioning mechanism further includes a stop cylinder and a fixed guide sleeve, wherein the stop cylinder and the fixed guide sleeve are respectively disposed at both ends of the frame and on both sides of the inner wall of the battery compartment, and the telescopic end of the stop cylinder is inserted into the fixed guide sleeve.

[0009] Optionally, multiple fixed guide sleeves are provided, and the multiple fixed guide sleeves are respectively disposed above multiple battery mounting seats in the battery compartment.

[0010] Optionally, each of the battery mounting brackets is provided with a through-beam sensor and a telescopic component above it, with each telescopic component spaced apart on the side of the through-beam sensor near the extension section.

[0011] Optionally, the chain drive assembly includes:

[0012] The drive motor and reducer are disposed between the two tracks and fixed inside the battery compartment;

[0013] Two universal couplings, one end of each universal coupling is connected to both ends of the output shaft of the reducer, and the other end of each universal coupling is provided with a drive sprocket;

[0014] Two passive sprockets are respectively rotatably mounted on one side of two tracks that are close to each other;

[0015] Each of the ring chains is coupled to one of the driving sprockets and one of the driven sprockets.

[0016] Optionally, the connecting component includes a connecting bracket and an inverted U-shaped connecting plate disposed below the connecting bracket. The connecting bracket is connected to the inner side of the lower end of the frame, and part of the annular chain is embedded in the opening of the connecting plate and fixedly connected to the connecting plate.

[0017] Optionally, the moving component is a traveling wheel, and the traveling wheel is provided with radially outward protruding limiting discs on both sides, the limiting discs being located on both sides of the track.

[0018] Optionally, a second micro switch is provided at the outer end of the extension section. The second micro switch is connected to the extension section via a mounting bracket, and is connected to the chain drive assembly and cooperates with the moving part.

[0019] This utility model provides a chain-type marine battery swapping trolley system, the advantages of which are as follows: This chain-type marine battery swapping trolley system has a track and a positioning mechanism. The battery swapping trolley moves relative to the track through the moving parts at the lower end of the frame's support legs. The trolley is driven by a chain-type drive mechanism. The frame is connected to a ring chain through connecting parts. The movement of the ring chain drives the battery swapping trolley to travel along the track. To ensure the positioning accuracy of the trolley when it reaches the battery swapping position, a positioning mechanism is used. The positioning mechanism emits a laser through the emitting end of a through-beam sensor, which is received by its receiving end. During the frame's movement, when the two ends of the frame move away from the extension section... When the first foot cuts off the optical path of the through-beam sensor, the through-beam sensor acts as a switch to activate the corresponding telescopic component. The telescopic end of the telescopic component drives the first micro switch to extend. As the frame continues to move, the two second feet of the frame near the extension section trigger the trigger end of the first micro switch. The first micro switch acts as a switch to close the chain drive assembly, causing the battery swapping trolley to stop moving. At this time, the battery swapping trolley can stop more accurately at its battery swapping position, that is, directly above a battery mounting seat. Through the setting of such a positioning mechanism, the accuracy of the chain-driven battery swapping trolley operation is improved, and it replaces the gear and rack drive mechanism, which can effectively save the overall cost of the battery swapping trolley.

[0029] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0030] like Figure 1 and Figure 2 As shown, this utility model provides a chain-type marine battery swapping trolley system, comprising:

[0031] Track 1, one end of which is fixed inside the battery compartment 2, and the other end of which can extend outside the battery compartment 2 to form an extension section 3;

[0032] The battery swapping trolley includes a frame 4 and a chain drive mechanism. The frame 4 includes four legs, and the lower end of the legs is provided with a moving part 7 that cooperates with the track 1. The frame 4 is used to house a lifting mechanism for lifting and lowering the battery hoist. The chain drive mechanism includes a ring chain 8 and a chain drive assembly. The frame 4 is connected to the ring chain 8 through a connecting part.

[0033] The positioning mechanism includes a through-beam sensor 9, a telescopic component 10, and a first micro switch 11. The through-beam sensor 9 is connected to the telescopic component 10, and the first micro switch is connected to the chain drive assembly. The through-beam sensor 9 and the telescopic component 10 are spaced apart on the inner wall of the battery compartment 2. The first micro switch 11 is located on the side of the telescopic end of the telescopic component 10 and is used to cooperate with the support leg.

[0034] Specifically, to address the issues of high cost associated with existing gear and rack drive mechanisms in marine battery swapping trolleys, and the difficulty in guaranteeing operational accuracy with other drive methods, this invention provides a chain-type marine battery swapping trolley system. This system includes a track 1 and a positioning mechanism. The trolley moves relative to the track 1 via a moving component 7 at the lower end of the support legs of the frame 4. The trolley is driven by a chain drive mechanism. The frame 4 is connected to a ring chain 8 via a connecting component. The ring chain 8 drives the trolley along the track 1. To ensure positioning accuracy when the trolley reaches the swapping position, a positioning mechanism is used. This mechanism emits a laser through the transmitter of a through-beam sensor 9, which is received by its receiver. The frame 4... During the movement, when the two first legs 5 of the frame 4 away from the extension section 3 cut off the optical path of the through-beam sensor 9, the through-beam sensor 9 acts as a switch to activate the corresponding telescopic component 10. The telescopic end of the telescopic component 10 drives the first micro switch 11 to extend. As the frame 4 continues to move, the two second legs 6 of the frame 4 near the extension section 3 trigger the trigger end of the first micro switch 11. The first micro switch 11 acts as a switch to close the chain drive assembly, causing the battery swapping trolley to stop moving. At this time, the battery swapping trolley can stop more accurately at its battery swapping position, that is, directly above a battery mounting seat. Through the setting of such a positioning mechanism, the accuracy of the chain-driven battery swapping trolley operation is improved, and the gear and rack drive mechanism is replaced, which can effectively save the overall cost of the battery swapping trolley.

[0035] Furthermore, when the trigger end of the first micro switch 11 is triggered, the first micro switch 11 can also act as a switch to restart the telescopic component 10, causing the telescopic end of the telescopic component 10 to retract, or a timer switch can be set so that the telescopic component 10 automatically retracts after extending for a set time.

[0036] Optionally, the telescopic component 10 is an electric telescopic rod or a telescopic electromagnet.

[0037] Optionally, the positioning mechanism also includes a stop cylinder 12 and a fixed guide sleeve 13. The stop cylinder 12 and the fixed guide sleeve 13 are respectively disposed at both ends of the frame 4 and on both sides of the inner wall of the battery compartment 2. The telescopic end of the stop cylinder 12 is inserted into the fixed guide sleeve 13.

[0038] Specifically, after the battery swapping trolley stops moving due to the actuation of the first micro switch 11, the positioning mechanism can further achieve battery swapping positioning through the cooperation of the stop cylinder 12 and the fixed guide sleeve 13. The stop cylinder 12 extends and inserts into the fixed guide sleeve 13 to further position the battery swapping trolley, ensuring positioning accuracy during the battery swapping process and improving the accuracy and safety of battery swapping.

[0039] In this embodiment, the telescopic section of the stop cylinder 12 is provided with a stop post, which can be inserted into the fixed guide sleeve 13. The fixed guide sleeve 13 is installed on the inner side of the battery compartment 2 through the mounting seat.

[0040] Optionally, multiple fixed guide sleeves 13 are provided, and the multiple fixed guide sleeves 13 are respectively provided above multiple battery mounting seats in the battery compartment 2.

[0041] Specifically, the fixed guide sleeve 13 is set one-to-one with each battery mounting seat, so that the stop cylinder 12 and the fixed guide sleeve 13 can cooperate in any battery replacement position.

[0042] Optionally, each battery mounting bracket is provided with a through-beam sensor 9 and a telescopic component 10 above it, with each telescopic component 10 spaced apart on the side of the through-beam sensor 9 near the extension section 3.

[0043] Specifically, the through-beam sensor 9 and the telescopic component 10 are also set one-to-one with each battery mounting seat. When swapping the battery on each battery mounting seat, the through-beam sensor 9 and the telescopic component 10 above the corresponding battery mounting seat, as well as the first micro switch 11, position the battery swapping trolley to ensure the accuracy of its stopping position and to ensure that the stop cylinder 12 can drive the stop post to be accurately and smoothly inserted into the corresponding fixed guide sleeve 13.

[0044] Furthermore, when the battery swapping trolley is stably fixed in a battery swapping position through the cooperation of the stop column and the fixed guide sleeve 13, the battery hoist can be lifted and lowered by the lifting mechanism. The lifting mechanism can be set as needed, such as a wire rope winding lifting mechanism, which suspends the battery hoist through the wire rope. Similarly, the battery hoist can also be set with a hoist adapted to the battery model as needed. For example, the hoist has a bearing plate and a clamp set on the lower side of the bearing plate. The clamps are set in pairs. When the clamps are closed, they can be inserted into the battery lifting interface to lift the battery. When the battery is placed on the battery mounting base or the battery buffer base outside the battery compartment 2, the clamps can be opened to detach from the battery. The clamps can be driven by an electric cylinder or a clamp cylinder, etc., which will not be limited or elaborated here.

[0045] Optionally, the chain drive component includes:

[0046] The drive motor and reducer 14 are set between the two tracks 1 and fixed inside the battery compartment 2;

[0047] Two universal couplings 15 are provided, one end of which is connected to both ends of the output shaft of the reducer 14, and the other end of each universal coupling 15 is provided with a drive sprocket 16.

[0048] Two passive sprockets are respectively mounted on one side of two tracks 1 that are close to each other;

[0049] Each ring chain 8 is coupled with a driving sprocket 16 and a driven sprocket.

[0050] Specifically, such as Figure 3 As shown, under the drive of the drive motor, the reducer 14 drives the two universal couplings 15 to rotate, and then drives the two ring chains 8 to run through the drive sprocket 16. Since the frame 4 of the battery swapping trolley is connected to the ring chains 8 through the connecting parts, the battery swapping trolley moves along the track 1 as the ring chains 8 run.

[0051] Optionally, the connecting component includes a connecting bracket 17 and an inverted U-shaped connecting plate 18 disposed below the connecting bracket 17. The connecting bracket 17 is connected to the inner side of the lower end of the frame 4, and a portion of the annular chain 8 is embedded in the opening of the connecting plate 18 and fixedly connected to the connecting plate 18.

[0052] Specifically, such as Figure 4 As shown, the connecting component is connected to the inner side of the frame 4 via the connecting bracket 17. The inverted U-shaped connecting plate 18 accommodates the embedding of a section of the ring chain 8 and can be fixedly connected to the ring chain 8 by welding, riveting, or other methods.

[0053] Optionally, the moving part 7 is a traveling wheel, and the two sides of the traveling wheel are provided with radially outward protruding limiting discs, which are located on both sides of the track 1.

[0054] Specifically, such as Figure 5 As shown, the limiting plates on both sides of the traveling wheel provide guidance for the interaction between the traveling wheel and the track 1, which is beneficial to the stability of the traveling wheel.

[0055] Optionally, a second micro switch 19 is provided at the outer end of the extension section 3. The second micro switch 19 is connected to the extension section 3 via a mounting bracket. The second micro switch 19 is connected to the chain drive assembly and cooperates with the moving part 7.

[0056] Specifically, when the battery swapping trolley moves to the battery swapping position on the extension 3 outside the battery compartment 2, that is, when the battery swapping trolley is directly above the battery buffer base, the second micro switch 19 is triggered by the battery swapping trolley, and the second micro switch 19 acts as a switch to close the chain drive assembly, so that the battery swapping trolley stops moving.

[0057] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
