Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and in particular to a battery pack transport device and battery pack transport equipment. Background Art

[0002] The energy storage container includes multiple battery packs. The energy storage container requires after-sales maintenance. During the after-sales maintenance process, the battery packs in the energy storage container often need to be replaced. In addition, the energy storage container is usually designed with only a single door, and the operating space for after-sales maintenance is very narrow.

[0003] Energy storage containers are often installed in remote areas, and the ground for installing the energy storage containers is usually uneven. In related technologies, forklifts are often used to transport battery packs. The forklifts have a lifting function, so that the forklifts can be lifted to a fixed height of the energy storage container for installing the battery packs. However, when the ground is uneven, an inclination angle will be formed between the installation surface of the energy storage container for installing the battery packs and the supporting surface of the forklift, which will cause the supporting surface of the forklift and the installation surface of the energy storage container for installing the battery packs to be unable to align, which will cause the forklift to be unable to directly deliver the battery pack to the installation surface of the battery pack of the energy storage container. The weight of the battery pack in the energy storage container can reach 780kgf, and the installation position of the battery pack cannot be directly adjusted by manpower, which makes the after-sales maintenance of the energy storage container very difficult.

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model. In the utility model, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0041] The energy storage container includes multiple battery packs. The energy storage container requires after-sales maintenance. During the after-sales maintenance process, the battery packs in the energy storage container often need to be replaced. In addition, the energy storage container is usually designed with only a single door, and the operating space for after-sales maintenance is very narrow.

[0042] Furthermore, energy storage containers are often installed in remote areas, and the ground for installing the energy storage containers is usually uneven. In the related art, a forklift 200 is often used to transfer battery packs. The forklift 200 has a lifting function, so that the forklift 200 can be lifted to a fixed height of the energy storage container for installing the battery pack. However, when the ground is uneven, an inclination angle is formed between the installation surface of the energy storage container for installing the battery pack and the supporting surface where the forklift 200 is located, which makes it impossible to align the transfer platform where the forklift 200 is located with the installation surface of the energy storage container for installing the battery pack, and thus makes it impossible for the forklift 200 to directly deliver the battery pack to the installation surface of the battery pack of the energy storage container. The weight of the battery pack in the energy storage container can reach 780kgf, and the installation position of the battery pack cannot be directly adjusted by manpower, which makes the after-sales maintenance of the energy storage container very difficult.

[0043] In one embodiment of the utility model, a battery pack transfer device 100 is provided, which can realize portable transportation of battery packs, take out battery packs from an energy storage container, and easily place replaced battery packs into a fixed position in the energy storage container, and can reduce the difficulty of manual operation.

[0044] refer to Figures 1 to 6 As shown, the battery pack transport device 100 includes:

[0045] A support platform 10 is used to place the battery pack of the energy storage container, and a universal disk 12 is provided at the bottom of the support platform 10;

[0046] The adjusting device 20 is connected to the supporting platform 10 and is used to drive the universal disk 12 to rotate so as to adjust the angle between the supporting platform 10 and the installation plane of the battery pack of the energy storage container.

[0047] By connecting an adjusting device 20 to the support platform 10, the adjusting device 20 is used to drive the universal disk 12 to rotate and thereby adjust the angle between the support platform 10 and the installation plane of the battery pack of the energy storage container. When the installation plane of the energy storage container is uneven, the universal disk 12 at the bottom of the support platform 10 connected to the adjusting device 20 is driven to rotate by the adjusting device 20, so that the support platform 10 can be rotated to a suitable angle, so that the plane where the support platform 10 is located is kept flush with the installation plane of the battery rack where the battery pack to be installed in the energy storage container is located, thereby facilitating the installation of the battery pack into the container-type energy storage container, and effectively improving the problem of difficult transportation of the battery pack in the energy storage container.

[0048] In some embodiments provided by the present invention, the adjusting device 20 includes a first adjusting device 21 and a second adjusting device 22 spaced apart from the first adjusting device 21 , and the second adjusting device 22 and the first adjusting device 21 are configured to drive the universal wheel 12 to rotate by adjusting the relative height of the first adjusting device 21 and the second adjusting device 22 .

[0049] By simultaneously arranging the first adjusting device 21 and the second adjusting device 22 on the first side surface 101 of the support platform 10, when the installation plane of the energy storage container is uneven, by driving one of the first adjusting device 21 or the second adjusting device 22 to perform lifting and lowering adjustment, the relative height of the first adjusting device 21 with respect to the second adjusting device 22 is adjusted, thereby driving the bottom universal disk 12 of the support platform 10 connected to the first adjusting device 21 and the second adjusting device 22 to rotate, so that the support platform 10 can be rotated to a suitable angle, so that the plane where the support platform 10 is located is kept flush with the installation plane of the battery pack to be installed in the energy storage container, thereby facilitating the installation of the battery pack into the container-type energy storage container.

[0050] Further references Figure 4 As shown, the battery pack transfer device 100 includes a base 11, and a universal disk 12 is arranged between the support platform 10 and the base 11. The tilt angle X between the support platform 10 and the base 11 can be changed by changing the rotation angle of the universal disk 12.

[0051] In some embodiments, the support platform 10 includes a first end 1011 and a second end 1012 that are arranged opposite to each other; the first adjustment device 21 is fixed near the first end 1011, and the second adjustment device 22 is fixed near the second end 1012. A first connection point is set between the first adjustment device 21 and the first side surface 101 of the support platform 10, and a second connection point is set between the second adjustment device 22 and the first side surface 101 of the support platform 10.

[0052] Taking the example of the first adjusting device 21 being closer to the entrance 41 of the battery pack transfer device 100 than the second adjusting device 22, when the installation plane of the energy storage container is level with the ground where the battery pack transfer device 100 is located, the support platform 10 can be adjusted to extend horizontally, and correspondingly, the first connection point on the first adjusting device 21 and the second connection point on the second adjusting device 22 can be configured to be at the same horizontal height.

[0053] When the installation plane of the energy storage container and the ground where the battery pack transfer device 100 is located are tilted downward, the support platform 10 is adjusted to tilt downward and keep it flush with the installation plane of the battery pack of the energy storage container, and the first connection point on the first adjustment device 21 is correspondingly adjusted to be lower than the second connection point on the second adjustment device 22, and the relative position height between the first connection point on the first adjustment device 21 and the second connection point on the second adjustment device 22 is adjusted so that the plane where the support platform 10 is located is level with the installation plane of the battery pack of the energy storage container.

[0054] When the installation plane of the energy storage container and the ground where the battery pack transfer device 100 is located are tilted upward, the support platform 10 is adjusted to be tilted upward and kept flush with the installation plane of the battery pack of the energy storage container, and the first connection point on the first adjustment device 21 is correspondingly adjusted to be higher than the second connection point on the second adjustment device 22, and the relative position height between the first connection point on the first adjustment device 21 and the second connection point on the second adjustment device 22 is adjusted so that the plane where the support platform 10 is located is level with the installation plane of the battery pack of the energy storage container.

[0055] In some embodiments, the first adjusting device 21 includes a screw adjusting assembly 23, or the second adjusting device 22 includes a screw adjusting assembly 23. The first adjusting device 21 and the second adjusting device 22 are both configured as screw adjusting assemblies 23 for illustration.

[0056] like Figure 4 and Figure 5 As shown, the screw adjustment assembly 23 includes a screw 231 , a nut 232 , a support bearing and a transmission screw coupling 233 .

[0057] The screw 231 is the core structural component of the screw adjustment assembly 23. The screw 231 is provided with a threaded structure. The screw 231 is made of metal or hard plastic to form a long rod-shaped body. In a preferred embodiment, the screw 231 is provided with a trapezoidal thread, and the trapezoidal thread structure is spirally wound on the outer surface of the screw 231 along the length direction of the screw 231.

[0058] The nut 232 is a component that is connected and cooperated with the threaded structure on the screw 231. The nut 232 is made of metal or hard plastic to be a cylinder with a hole structure or a polygonal column with a hole structure. When the screw 231 rotates, the screw 231 further drives the nut 232 to move on the threaded structure of the screw 231, thereby realizing the adjustment of the position of the nut 232.

[0059] The support bearing is used to support the screw rod 231 , thereby reducing the friction and wear of the screw rod 231 , so as to improve the stability and precision of the screw rod adjustment assembly 23 .

[0060] The transmission screw coupling is used to connect the screw 231 and the driving device to transmit the rotational motion.

[0061] In some embodiments provided by the present invention, the screw adjustment assembly 23 includes a plurality of screws 231, and a plurality of through holes are provided on the nut 232, each through hole is used for each screw 231 to pass through. In one example, the screw adjustment assembly 23 includes three screws 231, and three through holes are provided on the nut 232 at intervals.

[0062] Further references Figure 4 and Figure 5 As shown, the nut 232 of the screw adjustment assembly 23 is connected to the first side surface 101 on the support platform 10 through a linkage structure 24. The linkage structure 24 includes a linkage sleeve 241, a first linkage rod 242 and a second linkage rod 243. A first through hole and a second through hole are provided on the linkage sleeve 241. The first linkage rod 242 is roughly T-shaped. The base of the first linkage rod 242 is connected to the nut 232 of the screw adjustment assembly 23, and the rod body of the first linkage rod 242 is arranged through the first through hole. The second linkage rod 243 is roughly T-shaped. The base of the second linkage rod 243 is connected to the nut 232 of the screw adjustment assembly 23, and the rod body of the second linkage rod 243 is arranged through the second through hole.

[0063] Further references Figure 5 As shown, the first adjusting device 21 or the second adjusting device 22 includes a hand wheel 234, and the hand wheel 234 is used to drive the screw adjusting assembly 23 to rotate.

[0064] Furthermore, in other optional examples, an adjusting device 20 is connected to the first end 1011 or the second end 1012 of the support platform 10, and the second end 1012 or the first end 1011 of the support platform 10 is fixed, and the height of the adjusting device 20 is adjusted to drive the universal wheel 12 to rotate.

[0065] In other examples that can be selected, the first adjusting device 21 or the second adjusting device 22 can also be other lifting devices, such as an electric lifting device, a gear lifting device, a cylinder lifting device, etc. Among them, the electric lifting device is a device driven by an electric motor to lift or lower the height of the electric lifting device and thus change the height of the connection point between the electric lifting device and the support platform. The gear lifting device is mainly composed of gears, motors, bearings, etc., and the height of the gear lifting device is lifted or lowered by gear transmission to change the height of the connection point between the support platform and the gear lifting device. The cylinder lifting device is mainly composed of a cylinder, a control valve, and a pressure source. By changing the length of the cylinder, the cylinder lifting device is raised or lowered, thereby changing the height of the connection point between the cylinder lifting device and the support platform.

[0066] The battery pack transfer device 100 also includes at least one operating platform for an operator to stand. The support table 10 includes a first side surface 101 and a second side surface 102 that are arranged opposite to each other. A first adjustment device 21 is arranged at a first end 1011 close to the first side surface 101, and a second adjustment device 22 is arranged at a second end 1012 close to the first side surface 101. A first operating platform 31 and a second operating platform 32 are arranged on the battery pack transfer device 100, wherein the first operating platform 31 is arranged close to the first side surface 101, and the second operating platform 32 is arranged close to the second side surface 102, and the length of the first operating platform 31 extending is substantially the same as the length of the support table 10 extending, and the length of the second operating platform 32 extending is substantially the same as the length of the support table 10 extending, and the first adjustment device 21 is fixed at one end of the first operating platform 31, and the second adjustment device 22 is fixed at the other end of the first operating platform 31.

[0067] When the first adjusting device 21 needs to be adjusted, the operator can stand close to the first adjusting device 21 and drive the handwheel 234 of the first adjusting device 21 to rotate, thereby adjusting the vertical height of the first end 1011 of the support platform 10. When the second adjusting device 22 needs to be adjusted, the operator can stand close to the second adjusting device 22 and drive the handwheel 234 of the second adjusting device 22 to rotate, thereby adjusting the vertical height of the second end 1012 of the support platform 10.

[0068] In some embodiments, the first adjusting device 21 and the second adjusting device 22 can drive the universal disk 12 to rotate at an angle of ±X, where the angle range of X is 1° to 20°. According to the flatness of the bottom surface of the site where the energy storage container is located, the relative height between the first adjusting device 21 and the second adjusting device 22 is adjusted by rotating the hand wheel 234 to adjust the rotation angle of the universal disk 12, so that the support platform 10 of the battery pack transfer device 100 is flush with the installation plane where the battery pack inside the energy storage container is located. For example, by adjusting the relative height between the first adjusting device 21 and the second adjusting device 22, the universal disk 12 can rotate at an angle of ±5°, or by adjusting the relative height between the first adjusting device 21 and the second adjusting device 22, the universal disk 12 can rotate at an angle of ±10°. In other examples, the gimbal 12 may rotate by an angle of ±2, ±3, ±4, ±6, ±7, ±8, ±9, ±11, ±12, ±13, ±14, ±15, ±16, ±17, ±18, or ±19.

[0069] In some embodiments, the battery pack transport device 100 further includes a guardrail 40, which is configured to be detachably connected to the base 11, and the first operating platform 31 and the second operating platform 32 are located inside the guardrail 40. The guardrail 40 can prevent the operator from falling during operation, and the operator can lean on the guardrail 40 to increase safety when performing the battery pack transport operation. The guardrail 40 is configured to be detachable, and the detachable connection between the guardrail 40 and the base 11 can be at least one of a threaded connection, a magnetic connection, and a snap connection.

[0070] During the transportation of the battery pack transport device 100 , the guardrail 40 can be disassembled to reduce the volume of the battery pack transport device 100 for easy transportation. During the transportation of the battery pack by the battery pack transport device 100 , the guardrail 40 is installed on the base 11 .

[0071] In some embodiments, the battery pack transport device 100 further includes a winch mechanism 50 , which is fixed to one end of the support platform 10 , and the winch mechanism 50 is used to move the battery pack inside the energy storage container onto the support platform 10 .

[0072] The support platform 10 also includes a third side 103 and a fourth side 104 that are relatively arranged. The third side 103 is respectively connected to the top of the first side 101 and the second side 102, and the fourth side 104 is respectively connected to the bottom of the first side 101 and the second side 102. The winch mechanism 50 is arranged close to the third side 103, and the guardrail 40 is provided with an entrance 41 for the battery pack near the fourth side 104 of the support platform 10.

[0073] The winch mechanism 50 is a device for lifting or pulling a heavy object. In some embodiments, the winch mechanism 50 includes a drum, a gear, a transmission system and a drive device. By driving the drive device, the transmission system transmits power to the gear, and the gear then transmits power to the drum, thereby rotating it. The drive device can be a handle 51, and the drive device can also be an electric turntable.

[0074] The winch mechanism 50 is connected to the battery pack that needs to be replaced in the energy storage container through a traction device. The traction device can be a device for tightening or loosening ropes, steel cables or chains. When the drum of the winch mechanism 50 rotates, the winch mechanism 50 can tighten the rope, thereby dragging the battery pack that needs to be replaced inside the energy storage container onto the support platform 10. When the battery pack needs to be installed inside the energy storage container, the winch mechanism 50 loosens the rope to move the battery pack to the door of the energy storage container.

[0075] By setting up the winch mechanism 50, the battery pack can be directly pulled out from the battery rack of the energy storage container, reducing the difficulty and fatigue of manual operation. The handle 51 of the winch mechanism 50 is set close to the second operating platform 32, so that the operator can stand on the second operating platform 32 to operate conveniently.

[0076] In some embodiments, the support platform 10 includes a rolling mechanism 60, and the rolling mechanism 60 is used for the battery pack to roll. Compared with an ordinary conveyor belt, the rolling mechanism 60 uses rolling friction, while an ordinary conveyor belt uses sliding friction. The friction coefficient of rolling friction is larger than that of sliding friction, thereby facilitating pushing and pulling the battery pack into and out of the battery rack of the energy storage container, reducing the difficulty and fatigue of manual operation.

[0077] In some embodiments, the rolling mechanism 60 includes a plurality of rollers arranged at intervals; each roller is arranged along the width direction of the support platform 10. Alternatively, the rolling mechanism 60 includes a plurality of universal balls; or the rolling mechanism 60 includes a plurality of rolling bearings.

[0078] Further, the rolling mechanism 60 may be a part of the winch mechanism 50 .

[0079] In some embodiments, the battery pack transport device 100 further includes a latch 70, which is fixed to one end of the support platform 10, and is used to prevent the battery pack from being moved out of the support platform 10. The latch 70 is fixed at the entrance 41 at the fourth side surface 104 of the support platform 10, which can prevent the battery pack from falling during transport and installation.

[0080] In some embodiments, the battery pack transport device 100 further includes a forklift compatible seat 80, which is disposed at the bottom of the battery pack transport device 100. Two forklift compatible seats 80 are disposed at the bottom of the base 11 of the battery pack transport device 100, and the two forklift compatible seats 80 are adapted to the two fork legs on the forklift 200, so that the battery pack transport device 100 can be installed on the forklift 200.

[0081] In an embodiment of the present utility model, a method for removing a battery pack from an energy storage container is also provided, comprising:

[0082] Install the battery pack transfer device 100 on a forklift 200;

[0083] Raise the forklift 200 to the height of the battery rack where the battery pack to be replaced is located inside the energy storage container, and adjust the relative height between the first adjustment device 21 and the second adjustment device 22 to rotate the universal disk 12 to a certain angle, so that the plane where the support platform 10 of the battery pack transfer device 100 is located is flush with the plane where the battery rack is located;

[0084] Pull out the latch 70;

[0085] The battery pack on the battery rack is dragged onto the support platform 10 outside the energy storage container by using the winch mechanism 50;

[0086] The battery pack rolls on the rolling mechanism 60 on the support platform 10 to a fixed position;

[0087] Install the latch 70.

[0088] In an embodiment of the present utility model, a method for installing a battery pack inside an energy storage container is also provided, comprising:

[0089] The battery pack to be replaced is hoisted on the support platform 10 of the battery pack transport device 100;

[0090] Raise the forklift 200 to the height of the battery rack where the battery pack to be installed is located inside the energy storage container, and adjust the relative height between the first adjustment device 21 and the second adjustment device 22 to rotate the universal disk 12 to a certain angle, so that the plane where the support platform 10 of the battery pack transfer device 100 is located is flush with the plane where the battery rack is located;

[0091] Pull out the latch 70;

[0092] The winch mechanism 50 is used to move the battery pack on the support platform 10 to the door of the energy storage container.

[0093] In some embodiments of the present invention, the forklift compatible seat 80 on the battery pack transport device 100 can be adapted to the size of the fork legs of a forklift 200 commonly found on the market, and the battery pack transport device 100 can be sold independently.

[0094] In some embodiments of the present invention, a battery pack transport device 300 is also provided. Figure 7 As shown, the battery pack transfer equipment 300 includes a battery pack transfer device 100 and a battery pack transfer device 100 for being compatible with the forklift 200. The battery pack transfer equipment 300 is sold as a set of equipment.

[0095] There are usually multiple energy storage containers in the energy storage plant. In order to facilitate the normal operation and turnover of the battery pack transfer equipment 300, the interval between adjacent energy storage containers is slightly larger than the length of the battery pack transfer equipment 300. In one example, the interval between adjacent energy storage containers is 3.5m, and the length of the battery pack transfer equipment 300 is 2.4m. It is understandable that if the interval between adjacent energy storage containers is much larger than the length of the battery pack transfer equipment 300, it is not conducive to arranging as many energy storage containers as possible in the energy storage plant.

[0096] The above is a detailed introduction to the embodiments of the present invention.
