Description

Technical Field

[0001] The utility model relates to the technical field of energy storage battery pack replacement, in particular to a special machine for replacing energy storage battery packs. Background Art

[0002] In the complex integration process of energy storage systems, if the quality control fails during the manufacturing process, it may lead to faults in the battery packs at the energy storage site. Once a fault occurs, the faulty battery pack needs to be removed from the cabin for disassembly and repair, and then the repaired battery pack is reinstalled into the cabin. Currently, the single weight of common liquid-cooled battery packs is generally above 320 KG, making it difficult to disassemble manually. When the distance between battery cabins in an energy storage power station is large, a conventional forklift equipped with a tooling set matching the battery pack can be used for replacement. However, the overall length of the forklift is relatively long and the turning radius is large. Once the distance between battery cabins is reduced and the turning radius cannot be satisfied, this solution cannot be used.

[0003] With the rapid development of the energy storage industry, in order to achieve a higher energy density in energy storage power stations, the distance between energy storage devices has been gradually reduced, which also makes it difficult for conventional forklifts to pass through the narrow aisles between cabins and unable to meet the turning radius of the forklift, resulting in the inability to replace most battery packs. At present, for the need to replace battery packs in narrow aisles at the energy storage power station site, generally, a scaffolding is manually built and multiple people cooperate to achieve the replacement. This method not only has low efficiency but also has potential safety hazards.

[0004] Therefore, how to provide a special machine for replacing energy storage battery packs with a relatively high degree of automation to avoid the problems of low battery pack replacement efficiency and related safety hazards is a technical problem that needs to be solved by those skilled in the art at present.

[0035] In order to enable those skilled in the art in the technical field to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0036] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top" and "bottom" and the like is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0037] The purpose of the present invention is to provide a special machine for replacing energy storage battery packs, which can avoid the problems of low replacement efficiency of the battery pack 400 and related safety hazards.

[0038] Please refer to Figure 1 and Figure 2 , to achieve the above object, the present invention provides a special machine for replacing energy storage battery packs, including a frame 100 and a suspension platform 300 connected to the frame 100 through a moving mechanism. The suspension platform 300 is provided with a platform board 310 for placing the battery pack 400. One side of the frame 100 is provided with an electric control box 110 connected to the moving mechanism, so that an operating device 120 electrically connected to the electric control box 110 can control the moving mechanism to drive the suspension platform 300 to move to a preset height.

[0039] Wherein, rotatable pulleys 150 and universal wheels 160 with brakes are respectively provided at both ends of the bottom of the frame body 100 to support the frame body 100 and facilitate the movement of the frame body 100. When the special machine for replacing the energy storage battery pack is not needed, the special machine for replacing the energy storage battery pack can be moved to the idle area through the pulleys 150 and the universal wheels 160 without affecting the integration of the battery pack 400. When the special machine for replacing the energy storage battery pack is needed, the special machine for replacing the energy storage battery pack can be moved to the area to be replaced through the pulleys 150 and the universal wheels 160, and then the movement of the frame body 100 after reaching the position is restricted by braking.

[0040] When a battery pack 400 needs to be replaced, the special machine for replacing the energy storage battery pack is moved to the position to be replaced. Then, the operating device 120 is started to make the moving mechanism drive the lifting platform 300 to move to a preset height, and the battery pack 400 (PACK) is moved onto the platform plate 310 with a nearly the same height. Then, by starting the operating device 120 again, the moving mechanism drives the lifting platform 300 equipped with the battery pack 400 to move downward. With such a setting, the lifting platform 300 is connected to the moving mechanism and is constrained to move up and down on the frame body 100, thereby driving the battery pack 400 to rise and fall. The special machine for replacing the energy storage battery pack can be used to replace the battery pack 400 in the energy storage power station. It has a small floor area, is safe and reliable, and has high efficiency, and can avoid the problems of low replacement efficiency of the battery pack 400 and related safety hazards.

[0041] Please refer to Figure 3 , in this embodiment, the lifting platform 300 further includes side plates 320, a retaining bar 330, and a limiting structure. The side plates 320 are vertically arranged on both sides of the platform plate 310, and limiting grooves are formed in the side plates 320. The limiting grooves include a plurality of vertically spaced segments and an inclined segment communicating with all the vertical segments. The inclined segment is for the retaining bar 330 to enter the vertical segment, and the top of the inclined segment is higher than the bottom of the vertical segment to prevent the battery pack 400 located on the platform plate 310 from pushing the retaining bar 330 out of the limiting groove. After the battery pack 400 is transported to the platform plate 310, by detachably arranging the retaining bar 330 in different vertical segments of the limiting groove, the battery pack 400 can be restricted from sliding off one end of the platform plate 310;

[0042] The limiting structure includes a guide groove formed in the middle of the platform plate 310 and extending along its length direction, a rotating member 340 passing through the guide groove and capable of rotating around its own axis, and a blocking block 350 movably sleeved on the rotating member 340 and capable of slidingly cooperating with the guide groove. The blocking block 350 is higher than the platform plate 310 to prevent the battery pack 400 from sliding off the other end of the platform plate 310.

[0043] In some embodiments, the rotating member 340 can adopt a lead screw, and the axial movement of the lead screw installed on the hanging platform 300 is limited by a limit member. A screw hole adapted for the lead screw is provided on the stop block 350. The lead screw rotates around its own axis to drive the stop block 350 to approach and move away from the above-mentioned limit groove along the extension direction of the guide groove. After moving the stop block 350 to the end of the guide groove away from the limit groove, the battery pack 400 to be replaced is loaded into the hanging plate of the hanging platform 300. After installing the above-mentioned gear lever, the stop block 350 is driven to move toward the above-mentioned limit groove by rotating the lead screw until the stop block 350 can abut against the battery pack 400 to prevent the battery pack 400 from detaching from the hanging plate.

[0044] It can be understood that the rotating member 340 includes an extension section 341 extending to the outside of the hanging platform 300, and the end of the extension section 341 facing away from the hanging platform 300 is provided with a joint for connecting the rocker 360, so that the rotation of the rocker 360 can drive the rotating member 340 to rotate around its own axis, so that the stopper 350 can complete the above process. In addition, the outer periphery of the extension section 341 is provided with a connecting part, and the connecting part is connected to a power source that can drive it to rotate through a transmission member. The output end of the power source can drive the transmission member to rotate, and then drive the extension section 341 with the connecting part to rotate, so that the stopper 350 can also complete the above process. It can be selected according to actual conditions as long as it can achieve the above purpose.

[0045] In order to effectively reduce the friction between the battery pack 400 and the table 310, a plurality of positioning grooves are provided on the table 310, and a plurality of balls 370 are provided in the positioning grooves. A boss is provided at one end of the table 310 for the battery pack 400 to enter, and the top of the boss and the ball 370 are arranged at the same height. By arranging the boss and the ball 370 at the same height, the battery pack 400 passing through the boss can slide quickly onto the table 310 under the rolling of the ball 370, thereby reducing the friction between the battery pack 400 and the table 310 and improving the transfer efficiency of the battery pack 400.

[0046] In this embodiment, the side panels 320 are each provided with a vertically extending protrusion, and a slider is provided on the opposite sides of the two protrusions. The frame body 100 includes two vertical frames connected by a cross beam 130, and a vertically extending slide groove is opened on the vertical frame so that the hanging platform 300 driven by the moving mechanism drives the slider to slide along the extension direction of the slide groove.

[0047] It can be understood that a protrusion is provided on the side plate 320, and the guiding effect of the movement of the hanging platform 300 can be achieved through the sliding connection of the vertically extending slide groove and the slider provided on the side opposite to the protrusion. The slider is preferably a square, and linear bearings are preferably provided on both sides of the slider in contact with the slide groove to reduce the wear of the slider during the movement of the slide groove and increase the service life of the slider.

[0048] Among them, the moving mechanism includes a hydraulic component 210, gears and chains. The hydraulic component 210 is arranged on a vertical frame, and the hydraulic component 210 includes a cylinder body and a piston rod that are connected and can be relatively telescopic; when liquid enters the cylinder body, the piston rod is vertically lifted, and when the liquid in the cylinder body is discharged, the piston rod is vertically lowered. The gear is rotatably connected to the end of the piston rod away from the cylinder body, one end of the chain is fixed to the vertical frame, and the other end is fixedly connected to the side plate 320 through a connecting piece after the gear is engaged.

[0049] When liquid is introduced into the cylinder, the piston rod extends upward, driving the gear fitted with the chain part to rotate, so that the chain drives the hanging platform 300 to rise. When the liquid is discharged from the cylinder, the hanging platform 300 drives the chain downward under the action of its own gravity, causing the gear meshing with the chain to rotate in the opposite phase. At the same time, the chain presses down on the piston rod, causing the piston rod to retract downward. The liquid is electrically controlled to enter and exit the cylinder, thereby controlling the lifting and lowering of the hanging platform 300. It has the advantages of large stroke, wide range, and easy operation.

[0050] See also Figure 4 In this embodiment, the operating device 120 is provided with a first start button for controlling the liquid to enter the cylinder body and a second start button for controlling the liquid to be discharged from the cylinder body. There are two operating devices 120 and they are respectively arranged at different heights of two vertical frames. The electric control box 110 is arranged on the same side as the higher operating device 120, and a foldable wall-mounted telescopic ladder 111 is installed on the side wall of the electric control box 110, and a handrail 140 is provided in the middle of the vertical frame.

[0051] It should be noted that by arranging the two operating devices 120 at different heights of the two vertical frames, the operator can operate the hanging platform 300 according to different conditions. For example, when the hanging platform 300 is higher than the operator, the operator standing on the ground cannot determine whether the battery pack 400 is placed stably on the hanging platform 300. By unfolding the folded wall-mounted telescopic ladder 111 to the ground, the operator climbs up along the wall-mounted telescopic ladder 111 to a certain position with the handrail 140, and observes that the battery pack 400 is placed stably. Then, the operator can start the operating device 120 at a higher height and arranged on the same side as the electric control box 110 to complete the lifting and lowering of the hanging platform 300. When the hanging platform 300 is in a lower position, the operator can stand on the ground and control the lower operating device 120 to realize the lifting and lowering of the hanging platform 300, which is convenient for the operator to operate and can also cooperate with the engineer to climb up for maintenance operations.

[0052] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0053] In this specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0054] In this article, specific examples are used to elaborate on the principles and implementation manners of the present utility model. The descriptions of the above embodiments are only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the present utility model.
