Description

Technical Field

[0002] New energy locomotives, with their advantages of low noise, zero emissions, high torque, and low cost, have been widely adopted by enterprises in steel, mining, and other sectors. Conventional technology typically uses centralized charging to replenish the battery power of new energy locomotives when they are low. However, this long waiting time prevents new energy locomotives from quickly returning to production, significantly impacting enterprise productivity. Therefore, battery replacement has become an efficient and convenient method for replenishing locomotive power.

[0038] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0039] According to an embodiment of the present invention, a new energy locomotive rapid battery replacement system is provided. Figures 1 to 15 , including: a carrier 1, a battery cell 2 is arranged on the carrier 1, and a first connecting part 21 and a second connecting part 22 are arranged at intervals on the battery cell 2; a replacing device 3, a transmission component 4 and a moving component 5 are provided on the replacing device 3; the replacing device 3 is movably arranged on the side of the second connecting part 22 away from the first connecting part 21; the replacing device 3 has a first connection state connected to the first connecting part 21 and a second connection state connected to the second connecting part 22; when the replacing device 3 is in the first connection state, the transmission component 4 is driven to be connected to the first connecting part 21, so as to drive the first connecting part 21 to approach or move away from the replacing device 3 through the transmission component 4; when the replacing device 3 is in the second connection state, the moving component 5 is connected to the second connecting part 22, so as to drive the battery cell 2 to move through the moving component 5. Through the above-mentioned arrangement, the replacement device 3 is movably arranged, so that it is convenient to approach the carrier 1 that is inconvenient to move. In the first connection state, the transmission component 4 is first driven to connect with the first connecting part 21. When the replacement component 4 does not need to go deep into the interior of the carrier 1, the battery unit 2 is first moved on the carrier 1. Then, in the second connection state, the moving component 5 is connected with the second connecting part 22, and the battery unit 2 is driven to move to the replacement device 3 by the moving component 5. The battery unit 2 is provided with a first connecting part 21 and a second connecting part 22 spaced apart from each other. By driving the battery unit 2 to move, the new energy locomotive rapid battery replacement system can switch between different connection states to switch between different movement strokes, thereby reducing the travel requirements of the battery replacement equipment and correspondingly reducing the cost requirements of the battery replacement equipment. It solves the technical problems in the related technology that the centralized battery replacement of locomotives is inconvenient to move, the locomotive body is too deep, and the battery is bulky.

[0040] Specifically, the replacement device 3 can use a transport trolley, which can be flexibly moved and is convenient for approaching the carrier 1.

[0041] In the new energy locomotive rapid battery replacement system of this embodiment, see Figure 2 、 Figure 3The carrier 1 includes a sliding assembly 6, which includes: a screw rod 61, which is detachably connected to the first connecting component 21, and the sliding assembly 6 is detachably connected to the transmission assembly 4; a first movable seat 62, which is threadedly connected to the screw rod 61 and detachably connected to the first connecting component 21. When the screw rod 61 is connected to the transmission assembly 4 and the first movable seat 62 is connected to the first connecting component 21, the transmission assembly 4 drives the screw rod 61 to rotate, and the first movable seat 62 drives the battery unit 2 to move along the extension direction of the screw rod 61. In this way, the transmission assembly 4 on the replacement device 3 can drive the screw rod 61, and the first movable seat 62 is connected to the first connecting component 21 on the battery unit 2. The rotation of the screw rod 61 drives the battery unit 2 to move, and the battery unit 2 is removed from the body of the carrier 1 without requiring the replacement assembly 4 to penetrate into the interior of the carrier 1.

[0042] In the new energy locomotive rapid battery replacement system of this embodiment, see Figure 4 The moving assembly 5 includes: a first moving part 51, which is retractably arranged; a fixed part 52, which is fixedly arranged on the first moving part 51 and detachably connected to the second connecting part 22; an end of the fixed part 52 away from the first moving part 51 is used to connect to the second connecting part 22; and a first driving assembly 54, wherein the first moving part 51 is drivingly connected to the first driving assembly 54, and the first driving assembly 54 drives the first moving part 51 to extend or retract, thereby connecting or disconnecting the first moving part 51 from the second connecting part 22. In this way, when the battery unit 2 moves to the outside of the vehicle body 1, the fixed part 52 is connected to the second connecting part 22, and the moving assembly 5 moves the battery unit 2 to the replacement device 3, reducing the travel requirement of the first moving part 51 and simplifying the structure of the first moving part 51 and the replacement device 3.

[0043] In the new energy locomotive rapid battery replacement system of this embodiment, see Figure 4 The moving assembly 5 includes a guide shaft 53, a fixed component 52 sleeved on the guide shaft 53, and the fixed component 52 is movably arranged along the extension direction of the guide shaft 53. The transmission assembly 4 includes a rotating shaft 41, which is used to connect with the screw rod 61 to drive the screw rod 61 to rotate. The replacement device 3 includes a mounting plate 31, one side of which is connected to the guide shaft 53, and the other side of the mounting plate 31 is connected to the transmission assembly 4. The extension direction of the guide shaft 53 is arranged parallel to the rotation axis of the transmission assembly 4. This facilitates the docking of the battery unit 2 with the moving assembly 5 after it moves on the carrier 1.

[0044] Specifically, see Figure 5In the new energy locomotive rapid battery replacement system of this embodiment, the first drive assembly 54 includes a second movable part 541 and a second movable seat 542. The second movable seat 542 is movably arranged on the second movable part 541. The first movable part 51 is connected to the second movable seat 542. When the second movable part 541 rotates, the second movable seat 542 moves on the second movable part 541, causing the first movable part 51 to extend or retract.

[0045] Specifically, in the new energy locomotive rapid battery replacement system of this embodiment, the screw rod 61 is provided with a spline, and the rotating shaft 41 is provided with a spline guide sleeve. When the screw rod 61 is connected to the rotating shaft 41, the rotating shaft 41 can stably drive the screw rod 61 to rotate.

[0046] Specifically, the rotating shaft 41 provides driving force to the screw rod 61 by being connected to the output shaft of the motor.

[0047] In the new energy locomotive rapid battery replacement system of this embodiment, see Figure 4 The replacement device 3 also includes a passing component 7, which includes: a first extending arm 71, which is detachably connected to the carrier 1. When the first extending arm 71 is connected to the carrier 1, the moving component 5 drives the battery unit 2 to move to the replacement device 3 through the first extending arm 71; a support frame 72, and a roller is provided on the support frame 72. When the first extending arm 71 moves, the first extending arm 71 rolls on the support frame 72. Through the above arrangement, the passing component 7 builds a "bridge" between the carrier 1 and the replacement device 3, and the battery unit 2 moves to the replacement device 3 through the first extending arm 71. When the first extending arm 71 is extended to the carrier 1, the provision of the roller can make the first extending arm 71 extend more smoothly, thereby reducing the friction resistance of the first extending arm 71.

[0048] In the new energy locomotive rapid battery replacement system of this embodiment, see Figure 2 The carrier 1 includes a side plate 11 disposed opposite the replacement device 3, and a connection hole 111 is provided on the side plate 11. When connected to the carrier 1 through the component 7, the first extension arm 71 is inserted into the connection hole 111. The battery cell 2 is provided with a plurality of movable rollers 23, which are rotatably arranged. When the first extension arm 71 is connected to the carrier 1 and the movable component 5 drives the battery cell 2 to move to the replacement device 3, the movable rollers 23 roll on the first extension arm 71. In this way, the connection hole 111 can support the first extension arm 71 and can also limit the position of the first extension arm 71, ensuring smooth docking with the carrier 1 through the component 7. The provision of the movable rollers 23 makes the movement of the battery cell 2 smoother and reduces the frictional resistance of the battery cell 2.

[0049] Specifically, a rack is provided on the bottom surface of the first extending arm 71, and a gear set and a motor are provided on the replacement device 3. Through the gear rack transmission, the first extending arm 71 can be extended or retracted along its extension direction.

[0050] Specifically, the rotating shaft 41 is connected to the passing device 7 , and when the first extending arm 71 is extended, the rotating shaft 41 also moves therewith.

[0051] In the new energy locomotive rapid battery replacement system of this embodiment, see Figure 2 The carrier 1 is provided with a moving track 12 corresponding to the connecting hole 111, and the moving roller 23 is rollably arranged on the moving track 12. Specifically, the connecting hole 111 is arranged corresponding to the moving track 12 to ensure that the moving roller 23 moves in a straight line.

[0052] In the new energy locomotive rapid battery replacement system of this embodiment, see Figure 3 The carrier 1 includes a support plate 17, on which a movably mounted fixing post 13 is mounted. A fixing cylinder 24 is mounted on the battery cell 2. When the fixing post 13 extends beyond the support plate 17 and into the fixing cylinder 24, the fixing post 13 connects with the fixing cylinder 24 to restrict the position of the battery cell 2. The fixing post 13 and the fixing cylinder 24 secure and limit the position of the battery cell 2. When the battery cell 2 needs to be moved, the control system of the new energy locomotive controls the fixing post 13 to drop below the support plate 17, releasing the restriction on the battery cell 2.

[0053] In the new energy locomotive rapid battery replacement system of this embodiment, see Figure 6 The battery unit 2 includes a support frame 25, on which is mounted a material rack 26 for loading items to be shipped. The support frame 25 includes a first support rod 251, on which the first connecting member 21 and the second connecting member 22 are mounted; a second support rod 252, which is connected to the first support rod 251; and a fixing cylinder 24 connected to the second support rod 252. The fixing cylinders 24 are disposed on opposite sides of the first support rod 251. With this arrangement, the material rack 26 is used to accommodate batteries, supercapacitors, and the like. The fixing cylinders 24 are disposed on opposite sides of the first support rod 251, ensuring stable positioning of the large-mass battery unit 2.

[0054] Specifically, by setting the first connecting component 21 and the second connecting component 22 on opposite sides of the screw rod 61, the new energy locomotive rapid battery replacement system in this embodiment can switch between different connection states, making the movement and replacement of the battery unit 2 faster and more convenient.

[0055] In the new energy locomotive rapid battery replacement system of this embodiment, see Figure 7The battery cell 2 includes a carrier connection plate 27, which is provided with a guide sleeve 28. The carrier 1 includes a battery cell connection plate 14, which is provided with a guide post 15. When the battery cell 2 is connected to the carrier 1, the guide post 15 is inserted into the guide sleeve 28. The battery cell connection plate 14 is provided with a slider 16, and the carrier 1 is provided with a guide rail 18, to which the slider 16 is movably connected. Specifically, the carrier connection plate 27 and the battery cell connection plate 14 are provided with reserved openings for special quick connectors, which contain wiring harnesses for locomotive power and communications. By providing the slider 16 and guide rail 18, if the battery cell 2 is positioned offset when the battery cell 2 is about to be connected to the carrier 1, the battery cell connection plate 14 can slide on the guide rail 18 accordingly to adjust the position of the battery cell connection plate 14, thereby smoothly connecting the battery cell 2 to the carrier 1.

[0056] In the new energy locomotive rapid battery replacement system of this embodiment, see Figure 8 The first connecting component 21 and the second connecting component 22 are respectively provided with a connecting head 211; the carrier 1 and the moving component 5 are respectively provided with a connecting component 8, and the connecting component 8 includes: a connecting channel 81 for inserting the connecting head 211; a limiting component 82, and the limiting component 82 is movably provided on the side wall of the connecting channel 81; the connecting head 211 located in the connecting channel 81 is inserted through the limiting component 82 to connect the connecting component 8 to the connecting head 211, or the connecting component 8 is separated from the connecting head 211 by the limiting component 82 away from the connecting head 211.

[0057] Specifically, a connecting component 8 is respectively provided on the first movable seat 62 and the fixed component 52. By providing the connecting head 211 and the connecting component 8, the battery unit 2 can be automatically connected and separated from the carrier 1 and the movable component 5 without manual intervention. The operation is simple and quick, and the battery replacement efficiency of the locomotive is improved.

[0058] In the new energy locomotive rapid battery replacement system of this embodiment, see Figure 8The connector 211 includes a first connector 212 and a second connector 213, which are relatively movably arranged to form a connection slot 214 for inserting the limiting component 82 therebetween. The connector assembly 8 moves along a first preset direction, causing the limiting component 82 to slide into the connection slot 214. After the limiting component 82 slides into the connection slot 214, the connector assembly 8 moves along a second preset direction, thereby driving the limiting component 82 to move along the second preset direction. Specifically, when the limiting component 82 is inserted into the connection slot 214 and abuts against the first connector 212, the connector assembly 8 can pull the connector 211 to move as it moves, thereby pulling the battery cell 2 to move.

[0059] In the new energy locomotive rapid battery replacement system of this embodiment, see Figure 8 The connector 211 includes a connector base 215, which is spaced apart from the first connector 212 and the second connector 213. When the connector assembly 8 moves in the first predetermined direction, the connector assembly 8 abuts against the connector base 215, thereby pushing the connector 211 to move in the first predetermined direction. Thus, when the connector assembly 8 abuts against the connector base 215, the connector assembly 8 can push the connector 211 to move, thereby pushing the battery cell 2 to move.

[0060] In the new energy locomotive rapid battery replacement system of this embodiment, see Figure 8 The connector 211 includes a connecting rod 216, with a first connecting portion 212 and a second connecting portion 213 both disposed on the connecting rod 216. A first elastic member 217 is disposed on the connecting rod 216, with one end of the first elastic member 217 connected to the first connecting portion 212 and the other end connected to the second connecting portion 213. The connecting assembly 8 includes a limiting rod 83, which is inserted into the side wall of the connecting channel 81. A limiting component 82 is connected to the limiting rod 83, and a second elastic member 84 is sleeved on the limiting rod 83. One end of the second elastic member 84 is connected to the limiting component 82, and the other end is connected to the side wall of the connecting channel 81. Thus, by providing the first elastic member 217, a certain gap is always maintained between the first connecting portion 212 and the second connecting portion 213, thereby forming the connecting groove 214. By providing the second elastic member 84, the limiting component 82 can remain in a state where it can rebound into the connecting channel 81.

[0061] Specifically, the maximum outer diameter of the second connecting portion 213 is greater than the maximum outer diameter of the first connecting portion 212. As the connecting assembly 8 moves, when the limiting component 82 passes over the top of the second connecting portion 213, it is higher than the top of the first connecting portion 212. At this moment, due to the abutment of the limiting component 82, the first connecting portion 212 and the second connecting portion 213 remain in contact. Therefore, the limiting component 82 can pass over the top of the first connecting portion 212, thereby allowing the connector 211 to be smoothly detached from the connecting channel 81.

[0062] Specifically, see Figure 8 When the inclined surface of the first connecting portion 212 abuts against the limiting component 82, the limiting component 82 slides into the side wall of the connecting channel 81, the first connecting portion 212 passes over the limiting component 82, and the limiting component 82 slides into the connecting groove 214. Afterwards, the straight surface of the first connecting portion 212 abuts against the limiting component 82. At this time, the connecting component 8 moves in the direction away from the connecting seat 215. The connecting component 8 can pull the connecting head 211 to move, thereby pulling the battery unit 2 to move.

[0063] See also Figure 9 When the connecting component 8 moves toward the connecting seat 215, the inclined surface of the limiting component 82 abuts against the second connecting portion 213, causing the limiting component 82 to slide into the side wall of the connecting channel 81, so that the limiting component 82 passes over the second connecting portion 213 until the connecting component 8 abuts against the connecting seat 215. The connecting component 8 can push the connecting head 211 to move, thereby pushing the battery unit 2 to move.

[0064] See also Figure 10 In the above-mentioned connection state, when the connecting component 8 moves in the direction away from the connecting seat 215, the limiting component 82 abuts against the inclined surface of the second connecting portion 213, causing the limiting component 82 to slide into the side wall of the connecting channel 81. Because the maximum outer diameter of the second connecting portion 213 is greater than the maximum outer diameter of the first connecting portion 212, as the connecting component 8 moves in the direction away from the connecting seat 215, the limiting component 82 can pass over the first connecting portion 212 and the second connecting portion 213, and the connecting component 8 continues to move until the connecting head 211 is separated from the connecting channel 81.

[0065] The working process of the new energy locomotive rapid battery replacement system of this embodiment is as follows:

[0066] 1. See Figure 11 The replacement device 3 moves to the side of the carrier 1 and prepares to perform the battery replacement work. At this time, the connecting head 211 in the first connecting component 21 is connected to the connecting component 8 on the first movable seat 62, and the limiting component 82 is in the connecting groove 214.

[0067] 2. See Figure 12The first extending arm 71 extends out and connects to the connecting hole 111 , and the rotating shaft 41 is connected to the screw rod 61 .

[0068] 3. See Figure 13 The transmission component 4 drives the screw rod 61 to rotate. As the first movable seat 62 moves toward the side of the replacement device 3, the connecting component 8 abuts against the connecting seat 215. The connecting component 8 can push the connecting head 211 to move, thereby pushing the battery unit 2 to move until the battery unit 2 moves out of the vehicle body 1.

[0069] 4. See Figure 14 , the first movable part 51 extends out, the connecting head 211 in the second connecting part 22 is connected to the connecting assembly 8 on the fixed part 52 , and the limiting part 82 is in the connecting groove 214 .

[0070] 5. See Figure 1 The first movable part 51 shrinks in the direction away from the carrier 1. As the first movable part 51 shrinks, the connecting head 211 in the first connecting part 21 disengages from the connecting component 8 on the first movable seat 62, and the connecting component 8 on the fixed part 52 pulls the second connecting part 22 to move, causing the battery unit 2 to gradually move toward the replacement device 3.

[0071] 6. See Figure 15 When the battery unit 2 is completely moved onto the replacement device 3, the rotating shaft 41 is disconnected from the screw rod 61, the first extending arm 71 is retracted to the replacement device 3, and the first movable component 51 first pushes the fixed component 52 to move toward the direction of the carrier 1, and then pulls the fixed component 52 to move away from the carrier 1, so that the connecting head 211 in the second connecting component 22 is disengaged from the connecting component 8 on the fixed component 52.

[0072] 7. The replacement device 3 transports the recovered battery cell 2 to the charging location, transports the updated battery cell 2 back to the carrier 1, and repeats the above actions to install the updated battery cell 2 on the carrier 1, and the battery replacement is completed.

[0073] The new energy locomotive rapid battery replacement system of this embodiment is put into actual operation. By using a movable replacement device 3, it is possible to freely approach a carrier 1 that is difficult to move and transfer locomotive batteries, which solves the problem of inconvenient movement of locomotive centralized battery replacement, so that new energy locomotives do not need to wait for charging, and can be replaced and driven. The battery replacement work can be completed within 5 minutes, which greatly shortens the time. The replacement device 3 is provided with a transmission component 4 and a moving component 5. During the battery replacement process, different movement strokes can be switched by switching different connection states, which reduces the travel requirements of the battery replacement equipment and correspondingly reduces the cost requirements of the battery replacement equipment, solving the technical problems of the locomotive body being too deep and the battery being bulky. By providing a connector 211 and a connection component 8, the battery unit 2 can be automatically connected and separated from the carrier 1 and the moving component 5 without manual intervention. The operation is simple and quick, which improves the battery replacement efficiency of the locomotive.
