Description

Technical Field

[0001] The present invention relates to the technical field of new energy mining vehicles, and in particular to a battery replacement system for new energy mining vehicles. Background Art

[0002] Mining vehicles have good adaptability to mine roads, high vehicle weight utilization coefficient and light body weight. With the promotion and application of new energy mining vehicles in the mining field, they use advanced battery technology and drive systems to significantly reduce energy consumption and emissions, and improve the operating efficiency of mining areas. Compared with traditional fuel mining vehicles, new energy mining vehicles have obvious advantages in emission reduction, which helps mining areas to achieve green production.

[0003] Traditional battery swap stations need to be established at fixed locations with high one-time investment costs. General charging stations need to meet the battery swap and charging requirements of nearly 50 new energy mining trucks. They generally include a battery storage system, a battery swap robot system, a battery swap platform system, a charging control system, and a mobile power delivery mode to ensure that the batteries of new energy mining vehicles can be replaced efficiently and safely to meet the efficient operation requirements of mining operations.

[0004] However, in actual applications, in the process of open-pit mining, the route setting of mining vehicles often changes the operating route closely following the progress of mining, resulting in frequent changes in the operating route of mining vehicles. Therefore, the location of fixed large-scale battery swap stations has become the main problem restricting the operation of battery swap vehicles, but the relocation cost and difficulty of the already built battery swap stations are too high, resulting in the need for mining vehicles to leave the operating route and charge at fixed battery swap stations before running out of power during transportation on the operating route, thus failing to meet the existing mining progress and construction period requirements. Summary of the invention

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0071] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0072] This embodiment relates to a new energy mining vehicle battery replacement system. As a whole, Figures 1 to 3 As shown, the new energy mining battery exchange system includes a travel unit 1, a lifting unit 2 moving along the width direction of the travel unit 1, and a unit exchange unit 3 connected to the power output end of the lifting unit 2. The battery exchange unit includes a base frame 301, a positioning assembly 302 arranged on the side of the base frame 301 facing the battery box 6, and a locking assembly 5 arranged on the base frame 301.

[0073] Among them, an elastic sling 303 is also provided between the locking assembly 5 and the lifting unit 2, and the locking assembly 5 includes a trigger 304 connected to the elastic sling 303, and a slide groove 3051 is provided on the trigger 304. A guide assembly 4 is provided between the base frame 301 and the lifting unit 2. When the base frame 301 descends to a preset position, the positioning assembly 302 abuts against the length direction and the width direction of the battery box 6 for positioning, and the elastic sling 303 is in a free state and slides along the slide groove 3051; when the base frame 301 rises again, the elastic sling 303 elastically stretches to drive the trigger 304 to rotate, and the locking assembly 5 locks the battery box 6 on the base frame 301.

[0074] According to the above configuration, the new energy mining battery exchange system of this embodiment is provided with a travel unit 1, a lifting unit 2 and a battery exchange unit. When the vehicle is parked at a fixed position, the relative position of the lifting unit 2 and the battery box 6 on the vehicle is adjusted by the travel unit 1, and the lifting unit 2 is started, so that the battery exchange unit descends and gradually approaches the battery box 6. The positioning assembly 302 is abutted against the battery box 6 to position the base frame 301 and the frame position of the battery box 6 gradually correspond, until the base frame 301 completely corresponds to the top of the battery pack. The elastic sling 303 is in a free state due to the lack of gravity, and slides to a lower position along the slide groove 3051. When the lifting unit 2 is lifted upward, the elastic sling 303 is stretched by force to drive the trigger 304 to rotate, and the locking assembly 5 locks the frame of the base frame 301 and the battery box 6, thereby lifting the battery box 6 of the vehicle.

[0075] In addition, the new energy mining battery exchange system of this embodiment has a simple structure, and the battery box 6 can be replaced quickly and safely without the need for close manual operation, thereby ensuring personal safety. Moreover, due to the provision of a walking unit 1 and a lifting unit 2, it can adapt to the battery exchange adjustment of trams on different routes, and there is no need to build battery exchange stations. This improves the convenience of battery exchange for mining vehicles, adapts to the high efficiency requirements of mining vehicles, and reduces enterprise costs.

[0076] Based on the above overall introduction, an exemplary structure of the new energy mining power exchange system of this embodiment is as follows: Figures 1 to 3 As shown, the battery swap system can be set up on the route where the vehicle passes according to the adjustment of different routes, and can adapt to the needs of route adjustment. Since the battery swap system has a simple structure and is easy to install, the various components can be transported to the location by transport vehicles.

[0077] As an exemplary structure, Figures 1 to 3As shown, the walking unit 1 of this embodiment includes a track 101 arranged on the ground, a gantry 102 slidably connected to the track 101, and a first driving part 103 driving the gantry 102 to move along the front and rear direction of the vehicle, and the lifting unit 2 is arranged on the upper part of the gantry 102. The arrangement of the gantry 102 is the same as that of the prior art, and will not be repeated here. The first driving part 103 of this embodiment is a driving motor, a traveling wheel, a driving chain, etc., which is also the same as that of the prior art.

[0078] Further, as Figures 1 to 3 As shown, the lifting unit 2 includes a traveling mechanism 201 and a lifting mechanism 202 disposed on the traveling mechanism 201. The traveling mechanism 201 moves along the width direction of the gantry 102, and the lifting mechanism 202 includes a plurality of slings 203 connected to a base frame 301, and a mounting seat 204 corresponding to the slings 203 is disposed on the base frame 301. The traveling mechanism 201 of this embodiment is a traveling trolley that drives the lifting mechanism 202, and the lifting mechanism 202 is a crane used in the prior art.

[0079] As a preferred implementation mode, Figures 3 to 6 As shown, the guide assembly 4 includes a guide pin 401 connected to the base frame 301, and a guide tube 402 corresponding to the guide pin 401 is provided on the walking mechanism 201. When the base frame 301 is driven to move up and down, the guide pin 401 moves along the guide tube 402. This embodiment uses a four-rope lifting method for balanced lifting, and the base frame 301 is driven by the connection between the sling 203 and the mounting seat 204.

[0080] As mentioned above, Figures 3 to 7 As shown, four guide pins 401 are provided above the base frame 301 . The guide pins 401 are provided with a gradually decreasing conical sharp angle toward the guide tubes 402 . The four guide tubes 402 are provided in a one-to-one correspondence with the four guide pins 401 .

[0081] Preferably, if Figure 7 As shown, the guide tube 402 of this embodiment includes a connecting plate 4021, a vertical conduit 4022, and a tapered conduit 4023, and the taper of the tapered conduit 4023 is gradually increased from the vertical conduit 4022 to the direction of the guide pin 401. The connecting plate 4021 is used to set bolts to fix the guide tube 402 to the bottom of the traveling trolley. The inner hole of the vertical conduit 4022 is adapted to the outer diameter of the guide pin 401. Such a setting can not only reduce the movement error of the base frame 301 when the traveling trolley is driven, but also because the guide tube 402 is set on the inner side of the four slings 203, the base frame 301 is prevented from rotating and dislocating when descending, and the problem of the base frame 301 being difficult to position with the battery box 6 frame is avoided.

[0082] In addition, it should be pointed out that during the lifting process after the battery box 6 and the base frame 301 are locked, the guide pin 401 cooperates with the guide tube 402 to ensure that the walking trolley and the battery box 6 have a hard connection when moving along the width direction of the gantry 102, thereby avoiding the problem of heavy objects swinging, which not only protects the battery box 6 from damage and bumps, but also improves environmental safety.

[0083] As a preferred implementation mode, Figure 8 As shown, the positioning assembly 302 includes a connecting seat 3021, a plurality of adjusting plates 3022 arranged on the connecting seat 3021, and a positioning plate 3023 connected to the adjusting plate 3022. The connecting seat 3021 includes a flat plate 30211 and an inclined plate 30212 arranged at an angle, and two side plates 30213 connected to both sides of the flat plate 30211 and the inclined plate 30212, a buffer cavity 30214 is formed on the back of the inclined plate 30212, the adjusting plates 3022 and the positioning plates 3023 are both connected to the inclined plate 30212, and the positioning plates 3023 are arranged at a preset angle with the base frame 301.

[0084] In this embodiment, by providing the connection seat 3021, the adjustment plate 3022 and the positioning plate 3023, the overall thickness of the positioning assembly 302 can be adaptively adjusted according to the number of the adjustment plates 3022, thereby improving the positioning accuracy. In addition, since a buffer cavity 30214 is provided on the back of the inclined plate 30212, when the base frame 301 abuts against the battery box 6, vibration damage to the battery box 6 caused by hard contact is avoided, and the impact force is reduced by the buffer cavity 30214.

[0085] More specifically, the numerical range of the preset angle is between 115° and 125°. For example, it can be any value such as 115°, 116°, 117°, 118°, 119°, 120°, 121°, 122°, 123°, 124°, 125°, etc. The numerical range of the preset angle is between 115° and 125°, so that the positioning plate 3023 is gradually inserted into the frame of the battery box 6, and the positioning can be easily achieved due to the tension of the sling at the upper end of the base frame 301, thereby ensuring the positioning effect.

[0086] like Figure 4 and Figure 5 As shown, two positioning components 302 are arranged opposite to each other along the length direction of the base frame 301, and four positioning components 302 are arranged opposite to each other in the width direction of the base frame 301. A positioning frame 602 corresponding to the positioning components 302 is provided above the battery box 6. When the base frame 301 is lowered onto the battery box 6, each positioning component 302 is abutted and connected with the positioning frame 602. By respectively arranging relative positioning components 302 in the length direction and the width direction of the base frame 301, a rectangular conical guide is formed between each positioning plate 3023. This guiding method facilitates smooth positioning and improves positioning speed.

[0087] like Fig. 9 As shown, a positioning frame 602 is provided on the frame at the upper part of the battery box 6, and the positioning frame 602 is composed of two rectangular frames arranged at intervals. The positioning plates 3023 of the two positioning components 302 arranged along the length direction respectively abut against the vertical beams at the edges of the two rectangular frames, and the positioning plates 3023 of the two groups of positioning components 302 arranged along the width direction respectively abut against the horizontal beams at the edges of the two rectangular frames. By adding the positioning frame 602, the direct abutment between the positioning components 302 and the frame of the battery box 6 to cause wear can be avoided.

[0088] In addition, if Figures 11 to 13 As shown, the locking assembly 5 includes a rotating shaft 501 pivotally connected to the base frame 301, rotating arms 502 respectively connected to both sides of the rotating shaft 501, a first adjusting rod 503 and a second adjusting rod 504 respectively hinged on the rotating arms 502, and a locking pin 505 respectively connected to the first adjusting rod 503 and the second adjusting rod 504, the trigger member 304 is connected to the middle of the rotating shaft 501, and the hinges between the first adjusting rod 503 and the second adjusting rod 504 and the rotating arm 502 are eccentrically arranged with respect to the rotating shaft 501.

[0089] like Figures 11 to 13 As shown, the structures of the first adjusting rod 503 and the second adjusting rod 504 are composed of a straight rod and a steering ball head arranged at both ends, and nuts arranged at both ends of the straight rod. With such a configuration, the length of the first adjusting rod 503 and the second adjusting rod 504 can be fine-tuned, and the flexibility of the movement of the first adjusting rod 503 and the second adjusting rod 504 can be increased by setting the steering ball head.

[0090] And, if Figures 10 to 13 As shown, the lock pin 505 includes a rotating plate 5051, a vertical shaft 5052, and a pin body 5053. A locking groove 601 is provided at the corner of the battery box 6, the length of the locking groove 601 is greater than the length of the pin body 5053, and the width of the locking groove 601 is less than the length of the pin body 5053. When in the locked state, the length direction of the pin body 5053 is perpendicular to the length direction of the locking groove 601.

[0091] The new energy mining battery exchange system of this embodiment uses the new energy mining vehicle as the carrier. The new energy battery exchange vehicle drives to the designated location, and the professional personnel moves the special battery exchange crane to the bottom of the power battery pack, and performs the steps of lowering, aligning, locking, and hoisting the battery exchange hoist. After the power battery to be charged is hoisted and disassembled and placed in the storage area, the fully charged power battery pack is hoisted onto the new energy mining vehicle, thereby realizing the battery exchange function.

[0092] The new energy mining battery replacement system of this embodiment has a simple structure, and the battery box 6 can be replaced quickly and safely without the need for close manual operation, thus ensuring personal safety. In addition, due to the provision of a walking unit 1 and a lifting unit 2, it can adapt to the battery replacement adjustment of trams on different routes, without the need to build battery replacement stations, thereby improving the convenience of battery replacement for mining vehicles, adapting to the high efficiency requirements of mining vehicles, and reducing enterprise costs.

[0093] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
