Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, specifically to an auxiliary device for replacing energy storage batteries. Background Technology

[0002] To facilitate battery system integration and maintenance, energy storage battery systems generally adopt a modular architecture design. For example, energy storage battery clusters are typically mounted on battery racks in a three-dimensional layout.

[0003] Because energy storage batteries are quite heavy, replacing and maintaining damaged batteries is a difficult and time-consuming task, requiring multiple people to work together to erect multi-layered scaffolding and use cranes for battery replacement. However, during the actual lifting process, it was found that the batteries are prone to swaying due to the hoisting ropes, posing a significant safety hazard to workers standing on scaffolding while using cranes to replace batteries. Utility Model Content

[0004] In view of this, the present invention provides an auxiliary device for replacing energy storage batteries to solve the problem of significant safety hazards posed by workers standing on scaffolding to cooperate with cranes in replacing energy storage batteries.

[0005] Specifically, the energy storage battery replacement auxiliary device provided by this utility model includes a load-bearing module and a pick-and-place module. The load-bearing module includes a load-bearing platform and a support rod. The load-bearing platform is installed on the ground surface, one end of the support rod is connected to the load-bearing platform, and the other end of the support rod extends in a direction away from the load-bearing platform.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0034] According to embodiments of the present invention, such as Figure 1 As shown, an auxiliary device for replacing energy storage batteries is provided, including a load-bearing module 1 and a pick-and-place module 2.

[0035] Specifically, such as Figure 1 and Figure 2 As shown, the load-bearing module 1 includes a load-bearing platform 11 and a support rod 12. Both the load-bearing platform 11 and the support rod 12 are installed on the ground surface. One end of the support rod 12 is connected to the load-bearing platform 11, and the other end of the support rod 12 extends in a direction away from the load-bearing platform 11.

[0036] This configuration, by using a load-bearing platform 11 that contacts the ground surface, increases the contact area with the ground and reduces the pressure on a single point, thereby reducing the risk of overturning and helping to improve the stability of the entire device structure.

[0037] The pick-and-place module 2 is mounted on the load-bearing module 1 via a support rod 12. The pick-and-place module 2 includes a main support platform 21 and a limiting side plate group 22. The limiting side plate group 22 is arranged around the outer edge of the main support platform 21 and encloses a receiving chamber with an opening on the battery outlet side near the battery bracket and an opening on the top. The receiving chamber is used to place the energy storage battery.

[0038] Therefore, the limiting side plate group 22 and the main support platform 21 form a receiving chamber with an opening on the battery outlet side near the battery bracket and an opening on the top. After the device is installed on the outlet side near the battery bracket, if the energy storage battery needs to be replaced, the maintenance personnel only need to move the energy storage battery into the receiving chamber at the opening. During the relocation of the energy storage battery, the energy storage battery will be restricted by the limiting side plate group 22 and the main support platform 21, avoiding the phenomenon of the energy storage battery shaking when the maintenance personnel stand on the scaffolding to replace the energy storage battery with the crane.

[0039] It should be noted that, in the above embodiments, the overall shape of the load-bearing module 1 is not specifically limited.

[0040] At this time, the number of support rods 12 can be one, two or more. During installation, the installation method between support rods 12 and between support rods 12 and load-bearing platform 11 depends on the actual needs.

[0041] Preferably, when there are at least two support rods 12, some of the support rods 12 are arranged in parallel and spaced apart; and the support rods 12 can also be connected and fixed to each other so that the two support rods 12 present an L-shaped bending structure.

[0042] In one embodiment, such as Figure 1 and Figure 2 As shown, the pick-up and place module 2 is movably mounted on the support rod 12, and the direction of movement is vertical. The energy storage battery replacement auxiliary device also includes a lifting module 3, which includes a drive component 31. The drive end 311 of the drive component 31 is connected to the pick-up and place module 2, and the drive direction of the drive end 311 of the drive component 31 is vertical, which is used to adjust the height of the pick-up and place module 2.

[0043] With this configuration, by adding a lifting module 3 and making the driving direction of the driving end 311 of the driving component 31 in the lifting module 3 vertical, the height of the pick-up and put-down module 2 can be adjusted in a timely manner according to actual needs, so that the device can meet the needs of different installation height scenarios of energy storage batteries.

[0044] In one embodiment, such as Figure 1 and Figure 2 As shown, the lifting module 3 also includes a lifting platform 32, which is connected to the drive end 311 of the drive component 31, and the pick-up and place module 2 is placed above the lifting platform 32.

[0045] With this configuration, by adding a lifting platform 32 to the lifting module 3, a stable lifting foundation can be provided for the pick-up and drop-off module 2 and the energy storage battery to be processed.

[0046] In one embodiment, such as Figure 1 , Figure 2 , Figures 4 to 6 as well as Figure 8 As shown, the lifting module 3 also includes a guide rail 33 and a first pulley group.

[0047] Specifically, the guide rail 33 is elongated and has two grooves 331 extending along its length, with the openings of the two grooves 331 facing each other and away from each other; the first pulley group includes at least one pair of first pulleys 34, with each pair of first pulleys 34 rotatably mounted in the two grooves 331 respectively.

[0048] At this time, the lifting platform 32 is provided with a receiving groove 321 and a fixed shaft 322. The receiving groove 321 is used to receive the guide rail 33 and the first pulley group. One pair of opposite inner sidewalls of the receiving groove 321 are respectively installed at the openings of two grooves 331. The fixed shafts 322 are arranged in pairs and are respectively installed in two grooves 331. The central axis of any fixed shaft 322 is perpendicular to the inner bottom wall of the groove 331. The first pulley 34 is rotatably mounted on the fixed shaft 322.

[0049] With this configuration, the guide rail 33 is made into a long strip shape and has a groove 331 extending along the length direction. The openings of the two grooves 331 on the guide rail 33 are arranged opposite to each other, so that the two first pulleys 34 placed in the two grooves 331 can form a bidirectional limiting function.

[0050] That is, any pulley cannot move from its groove 331 to another groove 331 or cannot leave its groove 331, effectively offsetting the offset force generated during lifting and lowering, ensuring that the first pulley 34 placed inside can move linearly along a fixed path, and avoiding the phenomenon of pulley derailment due to excessive force on one side.

[0051] Preferably, the guide rail 33 has an H-shaped structure.

[0052] In one embodiment, it is still as follows Figure 1 , Figure 2 , Figures 4 to 6 as well as Figure 8 As shown, the lifting module 3 also includes a second pulley group and a limiting member 36.

[0053] Specifically, the second pulley assembly includes at least one second pulley 35, which is rotatably mounted on one of the outer wall surfaces opposite to the inner wall of any groove 331; the limiting member 36 is mounted on the other outer wall surface opposite to the inner wall of any groove 331.

[0054] The second pulley block and the limiting member 36 are used to restrict the first pulley block from moving horizontally within the groove 331. The horizontal direction is... Figure 5 Horizontal direction.

[0055] This configuration, by adding a second pulley group and rotatably mounting the second pulley 35 on one of the outer wall surfaces opposite to the inner sidewall of any groove 331, and mounting the limiting member 36 on the other outer wall surface opposite to the inner sidewall of any groove 331, allows the second pulley 35 to work in conjunction with the first pulley 34. This not only provides additional guidance but also further ensures that the first pulley 34 can move smoothly along a predetermined path. Furthermore, the limiting member 36 can work together with the second pulley 35 to form an effective constraint on the first pulley 34, significantly improving the stability of the entire lifting module 3 during operation.

[0056] In one embodiment, such as Figure 1 and Figure 2 As shown, the drive unit 31 is also provided with a fixed body 312. During installation, the fixed body 312 can be fixedly installed, and reinforcement measures are used to prevent the fixed body 312 from overturning during the movement of the drive end 311.

[0057] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, the fixed body 312 is installed above the load-bearing platform 11 and extends vertically; the lifting module 3 also includes a clamp 37, which has a clamp body 371 and two free ends 372 disposed at both ends of the clamp body 371. The inner circumferential contour of the clamp body 371 is at least partially adapted to the outer partial circumferential contour of the fixed body 312. Both free ends 372 are used to pass through the limiting member 36 and are connected to the locking member.

[0058] With this configuration, by adding a clamp 37 and adapting the inner axial contour of the clamp body 371 of the clamp 37 to the outer axial contour of the fixed body 312 of the drive member 31, during installation, it is only necessary to install the clamp body 371 of the clamp 37 to the outside of the fixed body 312 and gradually lock the clamp 37 after the free end 372 of the clamp 37 passes through the limiting member 36, thus locking the fixed body 312 and ensuring that the fixed body 312 cannot swing, thereby ensuring that the drive end 311 of the drive member 31 smoothly performs the lifting or lowering action.

[0059] Preferably, such as Figure 2 and Figure 7 As shown, clamp 37 has a U-shaped structure.

[0060] It should be noted that the number of guide rails 33 is not specifically limited in this application. There can be one, two or more.

[0061] In one embodiment, a guide rail 33 is provided. A first pulley assembly is installed in the groove 331 of the guide rail 33, and a second pulley assembly and a limiting member 36 are respectively provided on a pair of oppositely arranged outer sidewalls outside the groove 331.

[0062] In another implementation, to prevent the limiting member 36 from rotating around the fixed point, at least two guide rails 33 are provided, with a first pulley group and a second pulley group at at least one guide rail 33. The fixing body 312 is located between the guide rail 33 accommodating the first pulley group and the second pulley group and the adjacent guide rail 33; the two laterally extending ends of the limiting member 36 abut against the guide rail 33 accommodating the first pulley group and the second pulley group and the adjacent guide rail 33, respectively.

[0063] With this configuration, by using the limiting member 36 and having the two ends of the limiting member 36 extending laterally abut against the guide rail 33 and the adjacent guide rail 33 for accommodating the first pulley group and the second pulley group respectively, the limiting member 36 has multiple fixed points, avoiding the phenomenon of the limiting member 36 rotating around a fixed point, making the process of the drive member 31 raising or lowering the lifting platform 32 more reliable.

[0064] Preferably, such as Figure 2 As shown, two guide rails 33 are provided, and a first pulley group and a second pulley group are provided in the grooves 331 of both guide rails 33. The two ends of the limiting member 36 extending laterally abut against the two guide rails 33 used to accommodate the first pulley group and the second pulley group, respectively.

[0065] Similarly, as Figure 1 As shown, there can also be three guide rails 33, in which case the three guide rails 33 will form a stable support structure. For example, they can be arranged in a triangular pattern.

[0066] At this time, two of the guide rails 33 are used to install the first pulley group, the second pulley group and the limiting member 36, and the empty guide rails 33 are only used for support. For example, the two adjacent guide rails 33 are reinforced by using crossbeams, diagonal beams and other reinforcing members 39.

[0067] It can be noted that the surface of the load-bearing platform 11 is provided with several mounting holes, which correspond to the installation of the guide rail 33 and the fixed body 312 respectively.

[0068] During installation, the guide rail 33 is installed on the load-bearing platform 11 by fasteners such as bolts. The bottom of the fixing body 312 can be inserted into the corresponding mounting hole and locked with a clamp 37 at a certain distance above it.

[0069] In one embodiment, such as Figure 1 and Figure 2As shown, the lifting module 3 also includes a traction member 38, which forms a double-sided traction section around the drive end 311 of the drive member 31, and the double-sided traction section is used to pull the lifting platform 32 and the limiting member 36 respectively.

[0070] With this configuration, by setting up the traction member 38 and having the traction member 38 form a double-sided traction section around the drive end 311 of the drive member 31 to respectively traction the lifting platform 32 and the limiting member 36, the lifting platform 32 and the limiting member 36 can be raised and lowered synchronously. With the use of the first pulley 34 and the second pulley 35, the lifting platform 32 can maintain good straightness during the rising or falling process.

[0071] It should be noted that there is no specific limit to the number of traction components 38. There can be one or more.

[0072] Preferably, such as Figure 2 As shown, there are two traction components 38. At this time, there are two wheels at the drive end 311. Each wheel has a mounting groove to accommodate the traction component 38.

[0073] Preferably, the traction component 38 is a chain component, such as a chain, with adjacent chain links hooked together and having several insertion holes. At this time, the wheel mounting groove is provided with several meshing parts, such as toothed protrusions, and at least one toothed protrusion is used to insert into the insertion hole.

[0074] In one embodiment, such as Figure 1 and Figure 3 As shown, the pick-and-place module 2 also includes a secondary support platform 23, which is arranged between the lifting platform 32 and the main support platform 21 along the height direction.

[0075] With this configuration, by adding a secondary support platform 23 and installing the secondary support platform 23 between the lifting platform 32 and the main support platform 21 along the height direction, the secondary support platform 23 can provide a certain amount of additional height to the main support platform 21, which helps to reduce the amount of movement of the drive end 311 when replacing energy storage batteries with higher heights.

[0076] For example, the original lifting platform 32 is designed to be raised to a maximum height of 2m, and the secondary support platform 23 is 1m high. Therefore, with the use of the secondary support platform 23, the main support platform 21 located above the lifting platform 32 and the secondary support platform 23 can be raised to 3m.

[0077] It can be noted that the structure of the secondary support platform 23 is not specifically limited, as long as it has the ability to support and lift the main support platform 21.

[0078] Preferably, such as Figure 3 As shown, the secondary support platform 23 is equipped with four support legs.

[0079] Specifically, the tops of the four support legs are connected sequentially, and their top surfaces are at the same height. The bottoms of the four support legs can be spaced out or connected in pairs.

[0080] Similarly, as Figure 1 , Figure 2 and Figure 8 As shown, at this time, one of the outer edges of the lifting platform 32 extends upward so that the lifting platform 32 presents an L-shaped structure, forming a support chamber, and the auxiliary support platform 23 is installed in the support chamber.

[0081] It can be noted that, in order to further reduce the risk of safety accidents in mobile energy storage batteries, a slider (not shown) is provided at the bottom of the main support platform 21 and a slide rail (not shown) is provided at the top of the secondary support platform 23, so that the main support platform 21 can slide relative to the secondary support platform 23 under the action of external force, and the sliding direction is towards or away from the battery outlet side, so as to realize the action of pulling out and retracting.

[0082] It can be noted that the aforementioned secondary support platform 23 is installed above the lifting platform 32 using fasteners such as bolts.

[0083] In one embodiment, the pick-and-place module 2 further includes a flexible limiting member 24, and multiple flexible limiting members 24 are provided. The multiple flexible limiting members 24 are installed in at least one of the main support platform 21 and the limiting side plate group 22.

[0084] With this configuration, by providing a flexible limiting member 24 in at least one of the main support platform 21 and the limiting side plate group 22, the flexible limiting member 24 can fit tightly with the energy storage battery during the process of the energy storage battery entering and leaving the receiving chamber, reducing gaps and helping to buffer the energy storage battery during the process of taking the energy storage battery out of and out of the receiving chamber, reducing the damage caused by collisions or vibrations to the energy storage battery.

[0085] Preferably, such as Figure 1 and Figure 3 As shown, both the main support platform 21 and the limiting side plate assembly 22 are equipped with flexible limiting components 24.

[0086] It can be noted that the load-bearing platform 11, support rod 12, main support platform 21, limiting side plate assembly 22, auxiliary support platform 23, and lifting platform 32 used in the above embodiments are made of hot-dip galvanized steel, which gives them the advantages of being sturdy, durable, and resistant to corrosion and deformation.

[0087] It should be noted that when disassembling and replacing the energy storage battery, the auxiliary device for replacing the energy storage battery provided in the above embodiments needs to complete the assembly of the auxiliary device, which includes the assembly of the load-bearing module 1, the assembly of the lifting module 3, the assembly of the pick-and-place module 2, and the assembly between the modules.

[0088] Specifically, a load-bearing platform 11 and a support rod 12 are spliced ​​above the ground on the battery outlet side of the battery bracket; a guide rail 33 is installed in the mounting holes of the load-bearing platform 11 using fasteners such as bolts; the fixed body 312 of the drive unit 31 is installed in the mounting holes of the load-bearing platform 11 using fasteners such as bolts; the fixed body 312 is locked using a clamp 37 and a limiting member 36; a first pulley 34 and a second pulley 35 are installed in the groove 331 of the guide rail 33; a traction member 38 is used to connect the lifting platform 32 and the limiting member 36; and a secondary support platform 23 and a main support platform 21 are installed sequentially above the lifting platform 32.

[0089] In use, the drive end 311 of the drive unit 31 drives the main support platform 21 to rise until it moves to the battery outlet side. If the energy storage battery to be replaced is at a high height, a corresponding scaffold is erected at the auxiliary device. After the maintenance personnel move to the required height, the main support platform 21 is pulled out and connected to the battery bracket. Then, external force is applied to the energy storage battery to move it into the receiving chamber. The main support platform 21 is then restored to its initial position. The maintenance personnel then leave the scaffold and control the drive end 311 to lower the main support platform 21 until the lifting platform 32 is in place. The energy storage battery is then taken out from the receiving chamber and replaced. The main support platform 21 is then raised to the required height. The maintenance personnel then return to the scaffold and move to the target position. The main support platform 21 is pulled out and connected to the battery bracket. Then, external force is applied to the energy storage battery to move it from the receiving chamber into the battery bracket and fix it in place.

[0090] After use, the maintenance personnel retrieved the main support platform 21, then removed and dismantled the scaffolding, lowered the lifting platform 32, removed the main support platform 21, the auxiliary support platform 23, and the traction component 38, and took out the lifting platform 32, the limiting component 36, the first pulley 34, and the second pulley 35. Then, they removed the guide rail 33 and the drive component 31, and finally removed the load-bearing module 1, and took out the load-bearing platform 11 and the support rod 12.

[0091] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
