Technical Field

[0001] This utility model relates to the field of battery replacement technology for mining locomotives, and in particular to a fast battery swapping device for mining locomotives. Background Technology

[0002] Mining locomotives are core equipment for underground and surface auxiliary transportation in mines. They are mainly used to transport coal, ore, equipment materials, and personnel. With their stable power and adaptability to complex mining environments, they have become a key link in the mine production and logistics chain.

[0003] Among them, the battery-powered locomotive has an onboard rechargeable battery, eliminating the need for overhead wires. It is highly flexible and can run directly on tracks laid inside the mine. However, its range depends on the battery, requiring charging or battery replacement to keep the locomotive running continuously.

[0004] In traditional operations, charging the electric locomotive battery takes more than 8 hours. The electric locomotive battery is large in size, and the battery replacement process relies on manual operation, which is not only time-consuming and labor-intensive, but also prone to causing personal injury and equipment damage. Therefore, there is an urgent need for a fast battery replacement device for mining electric locomotives. Utility Model Content

[0007] Through the above technical solution, four rotating wheels are installed inside the two tracks, and multiple transverse reinforcing rods are fixedly welded inside the transfer frame to reinforce the transfer frame. The transfer frame is manufactured according to the size of the locomotive battery, and then four limiting frames are fixedly installed at the top four corners of the transfer frame to lock and limit the locomotive battery placed on the top of the transfer frame, preventing the battery from shifting or falling off the top of the transfer frame.

[0008] Preferably, four rollers are provided, arranged in a rectangular array at the bottom of the transfer frame. A slot is formed on the inner wall of the limiting frame, and the abutment is disposed inside the slot. Four limiting frames and four adjusting rods are provided, arranged in a rectangular array at the top four corners of the transfer frame.

[0009] Preferably, the lifting assembly includes a crossbeam frame, inside which a roller is rotatably mounted. A rotating tooth is fixedly mounted on the side of the roller away from the crossbeam frame. A fixed plate is provided on the side of the rotating tooth away from the roller. A rotating shaft is installed inside the roller. One end of the rotating shaft passes through the rotating tooth and extends into the interior of the fixed plate. A connecting shaft is rotatably mounted inside the fixed plate. One end of the connecting shaft passes through the fixed plate and is fitted with a rotating tooth. The other end of the connecting shaft passes through the fixed plate and is fitted with a drive motor.

[0010] Preferably, a connecting plate is fixedly installed at the bottom of the fixed plate, and an electric hoist is fixedly installed at the bottom of the connecting plate.

[0015] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Reference Figure 1-6 This utility model provides an embodiment of a fast battery swapping device for mining locomotives, comprising a track 1, a transfer frame 2 at the top of the track 1, a connecting frame 21 fixedly installed at the bottom of the transfer frame 2, a rotating wheel 22 rotatably installed inside the connecting frame 21, the rotating wheel 22 being disposed inside the track 1, a plurality of transverse reinforcing rods 201 fixedly installed inside the transfer frame 2, a limiting frame 202 fixedly installed at the top of the transfer frame 2, an adjusting rod 203 threadedly connected inside the limiting frame 202, a rotating block 204 fixedly installed at one end of the adjusting rod 203, a stop plate 205 rotatably installed at the other end of the adjusting rod 203, and a lifting assembly at the top of the transfer frame 2.

[0017] Four rotating wheels 22 are provided, arranged in a rectangular array at the bottom of the transfer frame 2. A slot 3 is provided on the inner wall of the limiting frame 202, and a stop plate 205 is disposed inside the slot 3. Four limiting frames 202 and four adjusting rods 203 are provided, arranged in a rectangular array at the top four corners of the transfer frame 2.

[0018] Two symmetrically distributed tracks 1 are laid inside the mine tunnel. Wheels 22 are fixedly installed at the bottom of a transfer frame 2 using a connecting frame 21. Four wheels 22 are rotatably installed inside the two tracks 1. Multiple transverse reinforcing rods 201 are fixedly welded inside the transfer frame 2 to reinforce it. The transfer frame 2 is manufactured according to the size of the locomotive battery. Four limiting frames 202 are fixedly installed at the top four corners of the transfer frame 2 to lock and limit the locomotive battery placed on top of the transfer frame 2, preventing the battery from shifting or falling off. An adjusting rod 203 is threaded into the limiting frame 202, allowing the adjusting rod 203 to rotate and move the abutment plate 205. After the battery is placed on top of the transfer frame 2, rotating the rotating block 204 drives the adjusting rod 203 to rotate, clamping the abutment plate 205 inside the slot 3 against the outer surface of the battery, further strengthening the limiting and fixing effect, thus achieving the effect of transferring and replacing the battery placed on top of the transfer frame 2.

[0019] It should be noted that the transfer frame 2 is connected to a traction device. When the traction device is activated, it can pull the transfer frame 2 to move inside the track 1 to transfer the battery.

[0020] Considering the question of how to move the battery from inside the locomotive and place it on top of the transfer rack 2, refer to Figures 4-6 The lifting assembly includes a crossbeam frame 41, inside which a roller 42 is rotatably mounted. A rotating gear 43 is fixedly mounted on the side of the roller 42 away from the crossbeam frame 41. A fixed plate 44 is provided on the side of the rotating gear 43 away from the roller 42. A rotating shaft 45 is installed inside the roller 42. One end of the rotating shaft 45 passes through the rotating gear 43 and extends into the interior of the fixed plate 44. A connecting shaft 46 is rotatably mounted inside the fixed plate 44. One end of the connecting shaft 46 passes through the fixed plate 44 and is fitted with a rotating gear 47. The other end of the connecting shaft 46 passes through the fixed plate 44 and is fitted with a drive motor 48.

[0021] A connecting plate 5 is fixedly installed on the bottom of the fixed plate 44, and an electric hoist 51 is fixedly installed on the bottom of the connecting plate 5. The tooth tip of the first rotating tooth 43 meshes with the tooth tip of the second rotating tooth 47. Multiple rollers 42 are provided, and the multiple rollers 42 are located inside the crossbeam frame 41 and distributed in a rectangular array.

[0022] The two ends of the crossbeam frame 41 are fixedly installed inside the wall of the mine tunnel, so that the crossbeam frame 41 is installed horizontally inside the mine tunnel. Multiple rollers 42 are rotatably installed inside the crossbeam frame 41, and a set of rollers 42 is provided with a rotating tooth 43 on the side away from the crossbeam frame 41. One end of the rotating shaft 45 passes through the fixing plate 44 and is rotatably inserted into the rotating tooth 43 and the roller 42. A connecting plate 5 is fixedly installed at the bottom of the fixing plate 44, and the bottom of the connecting plate 5 is fixedly installed at the top of the electric hoist 51, so that the electric hoist 51 can be suspended below the crossbeam frame 41 by means of the rollers 42. A rotating tooth 47 is fixedly sleeved on the outer surface of one end of the connecting shaft 46 through the fixing plate 44, so that the rotating tooth 47 can mesh with the rotating tooth 43. The drive motor 48 is connected. The electric starter drives the connecting shaft 46 and the first rotating gear 43 to rotate. The first rotating gear 43 drives the second rotating gear 47 and the roller 42 to rotate. In turn, the roller 42 can drive the electric hoist 51 to move along the crossbeam frame 41. When the electric hoist 51 is powered on, it lowers the steel cable and hook. The battery is hung on the hook of the steel cable by the strap at the top. Then the electric hoist 51 is started to drive the steel cable to wind up, lifting the hook and the battery. At the same time, the drive motor 48 is started to drive the roller 42 to rotate, so that the electric hoist 51 can move the lifted battery to the top of the transfer frame 2. Finally, the electric hoist 51 is started to lower the steel cable, so that the battery can be placed on the top of the transfer frame 2. The battery is transferred through the transfer frame 2, achieving the effect of lifting and quickly replacing the battery.

[0023] It should be noted that both the drive motor 48 and the electric hoist 51 are connected to the controller, which can control the start of the drive motor 48 and the electric hoist 51.

[0024] Working principle: When replacing the battery of the locomotive, the tunnel is equipped with two sets of tracks 1. One set of tracks 1 allows the locomotive to move, while the other set of tracks 1 is higher than the locomotive's track 1 and allows the transfer frame 2 to move. The transfer frame 2's track 1 is higher than the locomotive's track 1, facilitating the transfer of the battery. The operator moves the locomotive with the battery to be replaced under the electric hoist 51, and the transfer frame 2 is also moved under the electric hoist 51 via a traction device. The electric hoist 51 is then powered on, lowering the steel cable and hook. The battery is then hung on the hook of the steel cable via the strap at the top. The electric hoist 51 is then activated again to move the steel cable. The system retracts the hook and lifts the battery. Simultaneously, the drive motor 48 is started, rotating the roller 42 so that the electric hoist 51 can move the lifted battery to the top of the transfer frame 2. Finally, the electric hoist 51 is started to lower the steel cable, allowing the battery to be placed on top of the transfer frame 2. After the locomotive battery is placed on the transfer frame 2, the transfer frame 2 moves away with the battery. Another set of transfer frames 2, carrying a fully charged battery, moves to below the electric hoist 51. The operation is repeated in reverse to lift the fully charged battery from the top of the transfer frame 2 and install it inside the locomotive, achieving the effect of quickly replacing the locomotive battery. The battery replacement time for a single operation is reduced from several hours to about 15 minutes, and the stability of battery replacement is ensured. This not only improves work efficiency but also reduces the intensity of manual operation, providing a standardized solution for rapid energy replenishment in confined underground spaces.

[0025] When the electric hoist 51 places the battery to be charged on the top of the transfer frame 2, the battery is placed inside the four limiting brackets 202, which can lock and limit the four corners of the electric locomotive battery placed on the top of the transfer frame 2, preventing the battery from shifting or falling off the top of the transfer frame 2. By rotating the adjusting rod 203, the abutment 205 inside the slot 3 can be clamped and pressed against the outer surface of the battery, further strengthening the limiting and fixing of the battery to the top of the transfer frame 2, achieving the effect of limiting and fixing the battery placed on the top of the transfer frame 2 for transfer and replacement.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
