Description

Technical Field

[0001] This utility model relates to the field of energy storage battery packaging and maintenance technology, and more specifically, to a slide rail pallet fixture for transferring battery packs into cabinets. Background Technology

[0002] In large-scale energy storage projects (such as energy storage containers and 1000V / 1500V energy storage cabinets) and industrial and commercial energy storage projects, battery packs cannot be directly assembled into the cabinet manually due to their enormous weight (usually exceeding 350kg) and the height of the cabinet. Currently, there are two main assembly methods: one is to use a gantry crane to lift the battery pack and place it on the forklift's picks, then push the battery pack into the load-bearing guide rails inside the cabinet by lifting and moving the forklift; the other is to install two rows of rollers at the bottom of the battery pack, converting sliding friction into rolling friction to save effort.

[0003] However, these existing technologies have many defects and shortcomings: Structural damage risk: During the forklift insertion process, the forklift teeth will rub against the insulation cotton at the bottom of the battery pack, causing the insulation cotton to break and damaging the original structure of the battery pack.

[0004] High safety risks: The battery pack lacks effective restraint when placed on the forklift teeth, posing a risk of falling during transport and lifting.

[0005] Assembly efficiency is low: The forklift position needs to be adjusted repeatedly to precisely align the battery pack with the narrow guide rail slots in the cabinet, which is cumbersome and inefficient.

[0006] Maintenance and disassembly are inconvenient: Removing the battery pack from the cabinet for maintenance is laborious and extremely inconvenient.

[0007] Cost and space issues: Adding wheels to the bottom of the battery pack will increase additional material costs and also increase the overall height of the battery pack, affecting its stacking layout in the cabinet, which in turn increases the overall height and manufacturing cost of the battery cabinet.

[0008] Therefore, there is an urgent need in this field for a new type of tooling that can solve the above problems in order to achieve safe, efficient, low-cost assembly and maintenance operations without damaging the battery pack. Summary of the Invention

[0009] In view of this, and addressing the aforementioned technical pain points, this application proposes a sliding rail pallet fixture for battery pack transfer into a cabinet, comprising: a base structure, a limiting structure, a sliding structure, a positioning structure, and a fixing structure. During operation, the sliding rail pallet fixture is fixed to the forklift teeth via the fixing structure; the battery pack is lifted onto the fixture by a gantry crane, and the positioning structure achieves limiting in the front-back, left-right, and right directions; by aligning the positioning structure on the sliding rail pallet fixture with the positioning holes on the cabinet, precise positioning is achieved. Operators can easily push the battery pack along the sliding structure into the load-bearing guide rail of the cabinet or pull it out for maintenance. This application effectively solves the problems of easily scratched bottom insulation cotton of battery packs, risk of falling during transfer, low assembly efficiency, inconvenient maintenance, and high cost in the prior art, and has the beneficial effects of high safety, high efficiency, equipment protection, and cost reduction.

[0010] A slide rail pallet fixture for transferring battery packs into a cabinet includes: Base structure; Multiple limiting structures are installed on the base structure to limit the battery pack in the front, back, left and right directions. A sliding structure is used to support the battery pack and facilitate its insertion or removal; A fixed structure used to secure the tooling to the forklift gear; The positioning structure is used to cooperate with the positioning holes on the rack to achieve precise positioning.

[0011] In this technical solution, the base structure provides basic support for the entire fixture, bearing the weight of the battery pack and other structures. Multiple limiting structures on the base structure constrain the battery pack placed on the fixture from the front, back, left, and right directions, preventing it from shifting in those directions. The sliding structure bears the weight of the battery pack and, through its own structural characteristics (such as rolling friction design), reduces the resistance when pushing or pulling the battery pack, facilitating the operator to push or pull the battery pack into or out of the cabinet. The fixing structure uses mechanical fastening to stably connect the fixture to the forklift teeth, preventing the fixture from sliding or falling off during transport. The positioning structure precisely matches the pre-set positioning holes on the cabinet to determine the relative position of the fixture and the cabinet, ensuring the battery pack is accurately aligned with the load-bearing guide rails inside the cabinet. All these structures work together to complete the entire process of the battery pack's transport, cabinet placement, or maintenance.

[0012] In some embodiments, the sliding structure includes at least one set of rollers or guide rails disposed on both sides of the slide rail tray fixture to convert sliding friction into rolling friction.

[0013] In this technical solution, the sliding structure adopts at least one set of rollers or guide rails and is installed on both sides of the slide rail tray fixture. When the battery pack needs to be pushed into or pulled out of the cabinet, the battery pack contacts the sliding structure. Under the rolling action of the rollers or the guiding action of the guide rails, the sliding friction between the battery pack and the fixture is converted into rolling friction. According to the physical principle, the rolling friction force is much smaller than the sliding friction force, thereby greatly reducing the resistance when the battery pack moves.

[0014] In some embodiments, the limiting structure includes a front baffle, a left baffle, and a right baffle for limiting the battery pack in three directions.

[0015] In this technical solution, the limiting structure consists of a front baffle, a left baffle, and a right baffle. The front baffle is vertically installed at the front end of the base structure to block the battery pack from moving in the front-back direction and prevent the battery pack from sliding forward or shifting backward. The left baffle and the right baffle are vertically installed on the left and right sides of the base structure, respectively, to block the battery pack from the left and right directions and limit the battery pack from swaying or shifting in the left and right directions. The three baffles work together to form a stable constraint on the battery pack in the front-back, left-right, and right directions.

[0016] In some embodiments, a quick-release latch structure is also included for quickly locking or releasing the battery pack.

[0017] Furthermore, the quick-release latch structure can limit the fixing wedges on the battery pack in at least two directions.

[0018] In this technical solution, the quick-release locking structure is installed on the base structure and corresponds to specific parts of the battery pack, such as fixing wedges. After the battery pack is hoisted onto the fixture and initially positioned by the front, left, and right baffles, the quick-release locking structure is operated to quickly engage with the corresponding part of the battery pack, thus locking the battery pack. When it is necessary to release the battery pack, such as for cabinet installation or maintenance, the quick-release locking structure can be opened with simple operation, without complicated tools, to release the constraint on the battery pack.

[0019] The quick-release locking structure is designed for the fixing wedge on the battery pack. When locked, different parts of the locking structure contact the fixing wedge from at least two directions (such as the vertical direction and the front-back direction) and apply constraint force. For example, one part of the locking presses against the fixing wedge from above to restrict its vertical movement, while another part abuts against the fixing wedge from behind to restrict its front-back movement. Through multi-directional constraint, the fixing wedge is stably locked, thereby securing the battery pack.

[0020] In some embodiments, the fixing structure includes at least one manual knob bolt for fastening the slide rail pallet fixture to the forklift teeth.

[0021] In this technical solution, the fixing structure includes at least one manually operated knob bolt, which is installed at a corresponding position on the base structure, and its screw portion can be aligned with the side or a specific hole of the forklift tooth. When the forklift tooth is inserted into the hole of the base structure, the operator manually rotates the knob portion of the knob bolt, gradually tightening the screw and pressing it against the forklift tooth. The pressure between the screw and the forklift tooth generates friction, tightly fixing the base structure and the forklift tooth together and preventing relative sliding.

[0022] In some embodiments, the positioning structure includes at least one positioning pin for insertion into a positioning hole on the cabinet to align the tooling with the cabinet.

[0023] In this technical solution, the positioning structure includes at least one positioning pin, which is installed vertically or at a specific angle on the front end of the fixture or on one side of the corresponding cabinet. When the forklift moves the fixture next to the cabinet, the operator adjusts the forklift position so that the positioning pin is aligned with the positioning hole on the cabinet, and then slowly moves the forklift to insert the positioning pin into the positioning hole. At this time, the relative position of the fixture and the cabinet is precisely fixed, ensuring that the battery pack on the fixture is completely aligned with the load-bearing guide rail inside the cabinet.

[0024] In some embodiments, the base structure is a channel steel structure with holes for forklift tooth insertion.

[0025] In this technical solution, the base structure adopts a channel steel structure. Channel steel has the characteristics of high strength and high rigidity, which can withstand the weight of the battery pack (usually exceeding 350kg) and the impact force during transportation, providing a stable support foundation for the entire tooling. Holes for forklift tooth insertion are opened at specific positions in the channel steel structure. The size of the holes matches the cross-sectional size of the forklift tooth, ensuring that the forklift tooth can be smoothly inserted and fits tightly with the base structure after insertion, avoiding shaking.

[0026] Working principle: Fixture and forklift fixing: First, insert the forklift teeth into the preset holes on the base structure. After adjusting to the appropriate position, tighten the fixture by rotating the manual knob bolts in the fixing structure to firmly connect the fixture and the forklift teeth, preventing the fixture from sliding or falling off during transportation and providing a stable foundation for subsequent operations.

[0027] Battery pack hoisting and positioning: Using a gantry crane, the battery pack is hooked and hoisted onto the sliding structure of the tooling. At this point, the positioning structures on the base structure (front baffle, left baffle, right baffle) first provide initial positioning for the battery pack in three directions: front-back and left-right. Then, the quick-release locking structure applies positioning in at least two directions (up and back) to the fixing wedges on the battery pack, ultimately achieving reliable fixing of the battery pack in six directions: front-back, left-right, and up-down, preventing the battery pack from slipping during transport.

[0028] Tooling and rack positioning: Move the forklift to the rack and insert the positioning pins in the positioning structure of the tooling into the positioning holes of the rack. This quickly achieves precise alignment between the tooling and the rack, avoiding repeated adjustments to the forklift position and ensuring that the battery pack matches the position of the load-bearing guide rails inside the rack.

[0029] Battery pack installation and maintenance: After positioning, the operator can easily push the battery pack along the sliding structure (rollers or guide rails, which convert sliding friction into rolling friction) into the load-bearing guide rail of the cabinet to complete the assembly; if the battery pack needs maintenance, the reverse operation is performed to pull it out of the cabinet onto the tooling, and then it can be transported to the maintenance area by forklift.

[0030] The beneficial effects of this utility model are: The battery pack transfer slide rail tray fixture provided in this application has the following significant advantages: Effective protection of the battery pack structure: Since the battery pack is placed on the tooling rails or rollers, its bottom does not rub against any parts, completely avoiding the problem of the battery pack bottom insulation cotton being scratched by the forklift teeth during assembly, protecting the integrity of the equipment and improving the product yield.

[0031] Significantly improved safety: By setting up a front baffle, left and right baffles, and a quick-release locking structure, reliable limiting of the battery pack in six directions (front, back, left, right, up, and down) is achieved, which greatly reduces the risk of the battery pack falling off the forklift during transportation and lifting, and ensures the safety of personnel and equipment.

[0032] Assembly efficiency is greatly improved: By setting positioning pins on this tooling and cooperating with the positioning holes on the cabinet, the tooling and the cabinet can be aligned quickly and accurately without the need for tedious up, down, left and right fine adjustments by forklifts, simplifying the operation process and significantly improving production assembly efficiency.

[0033] Maintenance and disassembly are labor-saving and convenient: By using the rollers or guide rails on the fixture, sliding friction is converted into rolling friction. Operators can pull the battery pack out of the cabinet onto the fixture or push the battery pack into the cabinet with very little effort, making maintenance and disassembly operations easy and convenient.

[0034] Reduced costs and space requirements: This application eliminates the need to install individual casters at the bottom of each battery pack, saving material costs and installation time. It also avoids the increased battery pack height caused by adding casters, which facilitates compact stacking of battery packs within the cabinet and reduces the overall height and manufacturing cost of the battery cabinet.

[0040] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0041] Example: A slide rail pallet fixture for transferring battery packs into a cabinet includes: The base structure 101 serves as the base for the entire slide rail tray fixture 1, providing support for the remaining structures. Multiple limiting structures are provided on the base structure 101 to limit the battery pack 3 in the front, back, left and right directions. The sliding structure 105 is used to support the battery pack 3 and facilitate its pushing in or pulling out. A fixing structure is used to fix the tooling onto the forklift tooth 2; The positioning structure is used to cooperate with the positioning hole 402 on the cabinet 4 to achieve precise positioning.

[0042] In this technical solution, the base structure 101 provides basic support for the entire fixture, bearing the weight of the battery pack 3 and other structures. Multiple limiting structures on the base structure 101 constrain the battery pack 3 placed on the fixture from the front, back, left, and right directions, preventing it from shifting in those directions. The sliding structure 105 bears the weight of the battery pack 3 and, through its own structural characteristics (such as rolling friction design), reduces the resistance when pushing or pulling the battery pack 3, facilitating the operator to push or pull the battery pack 3 into or out of the cabinet 4. The fixing structure uses mechanical fastening to stably connect the fixture to the forklift teeth 2, preventing the fixture from sliding or falling off relative to the forklift teeth 2 during transport. The positioning structure precisely matches the pre-set positioning holes 402 on the cabinet 4 to determine the relative position of the fixture and the cabinet 4, ensuring that the battery pack 3 is accurately aligned with the load-bearing guide rail 401 inside the cabinet 4. All these structures work together to complete the entire process of the battery pack 3 from transport to cabinet entry or maintenance.

[0043] This enables integrated operation of battery pack 3 transfer, positioning, cabinet placement, and maintenance. Each structure has a clear division of labor and works together to ensure the stability and continuity of the entire operation process. It provides a basic framework for the subsequent optimization design of each dependent claim, and can further improve the performance of the tooling (such as adding quick-release latches, optimizing the sliding structure, etc.). The overall structural design is simple and comprehensive, and it is suitable for the transfer needs of battery pack 3 of different specifications in large-scale energy storage projects and industrial and commercial energy storage projects.

[0044] This invention solves the problem of the lack of unified and stable tooling support for the transfer and cabinet placement of battery pack 3 in existing technologies. In existing technologies, battery pack 3 is either placed directly on the forklift tooth 2 (without a dedicated limiting and positioning structure) or rollers are added to the bottom of battery pack 3 (increasing cost and height). The tooling proposed in this technical solution integrates support, limiting, sliding, fixing and positioning functions, providing a systematic solution for the transfer and cabinet placement of battery pack 3, avoiding the defects of scattered functions and cumbersome operation in existing technologies.

[0045] In some embodiments, the sliding structure 105 includes at least one set of rollers or guide rails, which are disposed on both sides of the slide rail tray fixture 1 to convert sliding friction into rolling friction. The battery pack 3 is placed on the sliding structure 105 to facilitate the pushing and pushing of the battery pack 3. When the sliding structure 105 uses rollers, the rollers 105 and bearings 109 are used in conjunction.

[0046] In this technical solution, the sliding structure 105 adopts at least one set of rollers or guide rails and is installed on both sides of the slide rail tray fixture 1. When the battery pack 3 needs to be pushed into or pulled out of the cabinet 4, the battery pack 3 contacts the sliding structure 105. Under the rolling action of the rollers or the guiding action of the guide rails, the sliding friction between the battery pack 3 and the fixture is converted into rolling friction. According to the physical principle, the rolling friction force is much smaller than the sliding friction force, thereby greatly reducing the resistance when the battery pack 3 moves.

[0047] Specifically, the battery pack 3 is placed on the sliding structure 105 throughout the entire process, and its bottom does not directly contact the forklift tooth 2 or other components. This completely avoids the problem of the forklift tooth scratching the insulation cotton at the bottom of the battery pack in the existing technology, ensuring the integrity of the original structure of the battery pack and improving the product yield.

[0048] The sliding structure 105 converts the sliding friction during the pushing and pulling of the battery pack into rolling friction. Operators can easily put the battery pack into the cabinet or pull it out manually without the need for additional equipment, which solves the problem of laborious disassembly in traditional maintenance and reduces the intensity of maintenance operations.

[0049] There is no need to install casters at the bottom of each battery pack, which directly saves on the material cost and installation time of the casters; at the same time, it avoids the increase in battery pack height caused by the addition of casters, does not affect the stacking layout of the battery packs in the cabinet, indirectly reduces the overall height of the battery cabinet and manufacturing cost, and reduces space occupation.

[0050] In some embodiments, the limiting structure includes a front baffle 102, a left baffle 103, and a right baffle 108, which are used to limit the battery pack 3 in three directions. Specifically, the front baffle 102 limits the battery pack 3 in the forward direction, while the left baffle 103 and right baffle 108 limit the battery pack 3 in the left and right directions and also serve as support bases for the roller 105 and bearing 109.

[0051] In this technical solution, the limiting structure consists of a front baffle 102, a left baffle 103, and a right baffle 108. The front baffle 102 is vertically disposed at the front end of the base structure 101 to block the movement of the battery pack 3 in the front-back direction and prevent the battery pack 3 from sliding forward or shifting backward. The left baffle 103 and the right baffle 108 are respectively vertically disposed on the left and right sides of the base structure 101 to block the battery pack 3 from the left and right directions, limiting the swaying or shifting of the battery pack 3 in the left and right directions. The three together form a stable constraint on the battery pack 3 in the front-back, left-back, and right directions.

[0052] This technical solution effectively limits the displacement of the battery pack 3 during the tooling transfer process by forming multi-directional physical protection, reducing the risk of collision or fall caused by shaking or displacement of the battery pack 3; it clearly defines the placement position of the battery pack 3 on the tooling, eliminating the need to repeatedly adjust the placement posture of the battery pack 3 and improving the efficiency of lifting and placing the battery pack 3; the baffle structure is simple and strong, and can withstand the inertial impact force of the battery pack 3 during the transfer process, ensuring the reliability of the overall tooling structure.

[0053] This invention addresses the problem in existing technologies where the battery pack 3, when placed on the forklift tooth 2, lacks effective restraint, posing a risk of falling. In existing technologies, the battery pack 3 is placed directly on the forklift tooth 2 without dedicated restraint, making it prone to displacement or even falling during transport or lifting due to bumps, turns, or other factors. This application utilizes a three-directional restraint design to provide stable restraint protection for the battery pack 3, significantly improving safety during transport.

[0054] In some embodiments, a quick-release locking structure 107 is also included for quickly locking or releasing the battery pack 3 to improve production efficiency. The quick-release locking structure 107 can limit the fixing wedge 301 on the battery pack 3 in at least two directions.

[0055] In this technical solution, the quick-release locking structure 107 is installed on the base structure 101 and corresponds to a specific part on the battery pack 3, such as the fixing wedge 301. After the battery pack 3 is hoisted onto the fixture and initially limited by the front, left, and right baffles, the quick-release locking structure 107 is operated to quickly engage with the corresponding part of the battery pack 3, thereby locking the battery pack 3. When it is necessary to release the battery pack 3, such as for cabinet installation or maintenance, the quick-release locking structure 107 can be opened with simple operation without complicated tools to release the constraint on the battery pack 3.

[0056] In this technical solution, the combined limiting design of "front baffle 102, left baffle 103, right baffle 108 and quick-release locking structure 107" achieves all-round fixation of the battery pack in six directions, which greatly reduces the risk of the battery pack falling during transportation and lifting, and avoids personal injury or equipment damage caused by the battery pack falling off, thus ensuring operational safety.

[0057] The system enables rapid locking and unlocking of battery pack 3 without the need for additional tools, simplifying the operation process and significantly reducing the time required to fix and disassemble battery pack 3, thereby improving assembly and maintenance efficiency. In the locked state, it further enhances the stability of battery pack 3, and together with the baffle limiter, it forms a more comprehensive fixing effect, reducing the risk of battery pack 3 falling off under extreme working conditions (such as forklift sudden stop or turning). The compact structural design does not occupy too much tooling space, and the operation is convenient, reducing the workload of operators.

[0058] This invention solves the problems of cumbersome and inefficient battery pack 3 fixing operations in existing technologies. In existing technologies, if reinforcement of the battery pack 3 is required, traditional connectors such as bolts are often used, requiring tools for installation and disassembly, which is time-consuming and labor-intensive; without reinforcement, safety is insufficient. The quick-release locking structure of this application balances fixing reliability and operational convenience, filling the functional gap of "efficient fixing and rapid release" in existing technologies.

[0059] like Figure 2 As shown in the enlarged diagram, the quick-release locking structure 107 can limit the fixing wedge 301 on the battery pack 3 in two directions (indicated by the arrows, the upward and backward directions). The quick-release locking structure 107 is designed for the fixing wedge 301 on the battery pack 3. When locked, different parts of the locking structure contact the fixing wedge 301 from at least two directions (such as the vertical direction and the front-back direction) and apply constraint force. For example, one part of the locking presses the fixing wedge 301 from above to restrict its vertical movement, and another part abuts the fixing wedge 301 from the rear to restrict its front-back movement. Through multi-directional constraints, the fixing wedge 301 is stably locked, thereby achieving the fixation of the battery pack 3.

[0060] Multi-directional limiting makes the battery pack 3 more securely fixed, avoiding loosening or displacement that may occur when locking in one direction. Even if the battery pack 3 is subjected to multi-directional external force impact during transportation, it can remain stable. The precise matching of the fixing wedge 301 on the battery pack 3 allows for automatic alignment during locking, reducing operation and adjustment time and improving locking accuracy and efficiency. The uniform distribution of the constraint force on the fixing wedge 301 prevents excessive local force from damaging the fixing wedge 301 or the locking structure, thus extending the service life of the components.

[0061] This invention addresses the problems of limited fixation methods and insufficient reliability in existing battery pack 3 fixing technologies. In existing technologies, some fixing structures can only constrain the battery pack 3 from a single direction, making them prone to failure due to external forces. This application, through a multi-directional locking design, significantly improves the stability and reliability of battery pack 3 fixing, further reducing safety risks during transportation.

[0062] The positioning structure includes at least one positioning pin 110, which is inserted into the positioning hole 402 on the cabinet 4 to achieve alignment between the tooling and the cabinet 4. The positioning pin 110 is inserted into the positioning hole 402 of the cabinet 4 to prevent the pallet from swinging up, down, left, and right.

[0063] In this technical solution, the positioning structure includes at least one positioning pin 110, which is installed vertically or at a specific angle on the front end of the tooling or on one side of the corresponding cabinet 4. When the forklift moves the tooling next to the cabinet 4, the operator adjusts the forklift position so that the positioning pin 110 is aligned with the positioning hole 402 on the cabinet 4, and then slowly moves the forklift to insert the positioning pin 110 into the positioning hole 402. At this time, the relative position of the tooling and the cabinet 4 is precisely fixed, ensuring that the battery pack 3 on the tooling is completely aligned with the load-bearing guide rail 401 inside the cabinet 4.

[0064] This technical solution enables rapid and accurate positioning of the tooling and cabinet 4, eliminating the need for repeated forklift adjustments, significantly reducing positioning time and improving the efficiency of battery 3 insertion into the cabinet. After positioning, there is no relative movement between the tooling and cabinet 4, ensuring that the battery pack 3 can accurately slide into the load-bearing guide rail 401 when pushed into the cabinet 4, avoiding jamming or collision of the battery pack 3 into the cabinet 4 due to positioning deviation, thus improving the safety and success rate of the insertion operation. The small gap between the positioning pin 110 and the positioning hole 402 ensures high positioning accuracy and is compatible with the narrow guide rail slots inside the cabinet 4, meeting the requirements of high-precision assembly.

[0065] This invention solves the problem of low assembly efficiency caused by the need for repeated forklift position adjustments when inserting the battery pack into the cabinet in existing technologies. Existing technologies rely on the forklift operator to manually adjust the forklift position to align with the cabinet guide rails, which is cumbersome and makes it difficult to guarantee positioning accuracy, easily leading to cabinet insertion failure or component collisions. The positioning pin design in this application achieves precise and rapid alignment between the tooling and the cabinet, significantly improving assembly efficiency and accuracy.

[0066] In some embodiments, the base structure 101 is a channel steel structure, and the load-bearing base made of channel steel is stable. It is provided with holes 104 for forklift teeth 2 to be inserted. The fixing structure includes at least one manual knob bolt 106 for fastening the slide rail pallet fixture 1 to the forklift teeth 2. The manual knob bolt 106 can be rotated to firmly fix the base structure 101 of the entire transfer slide rail pallet fixture 1 to the forklift teeth 2.

[0067] In this technical solution, the base structure 101 adopts a channel steel structure. The channel steel has the characteristics of high strength and high rigidity, which can withstand the weight of the battery pack 3 (usually exceeding 350kg) and the impact force during transportation, providing a stable support foundation for the entire tooling. Holes 104 for forklift tooth 2 to be inserted are opened at specific positions on the channel steel structure. The size of the holes matches the cross-sectional size of the forklift tooth 2, ensuring that the forklift tooth 2 can be smoothly inserted and fits tightly with the base structure 101 after insertion, avoiding shaking.

[0068] The channel steel base has high strength and light weight, which reduces the weight of the tooling itself while ensuring load-bearing capacity, thus reducing the load pressure on the forklift. The precise design of the 104 holes allows for quick positioning after the forklift tooth 2 is inserted, reducing the time required for docking and adjusting the tooling with the forklift. The channel steel has strong resistance to deformation, and it can maintain structural stability even after long-term use, avoiding the displacement of other structures of the tooling due to base deformation, and extending the overall service life of the tooling.

[0069] This invention addresses the problems of insufficient structural strength and poor adaptability of existing tooling bases. In existing technologies, some tooling bases are made of ordinary sheet metal, resulting in low strength and easy deformation; others have poorly designed hole positions, making it difficult or unstable forklift tooth insertion. The channel steel structure base and precise hole design of this application ensure that the base strength meets load-bearing requirements, while improving compatibility and docking stability with forklift teeth, thus guaranteeing the overall performance of the tooling.

[0070] In this technical solution, the fixing structure includes at least one manual knob bolt 106, which is installed at a corresponding position on the base structure 101, and its screw portion can be aligned with the side or a specific hole of the forklift tooth 2. When the forklift tooth 2 is inserted into the hole 104 of the base structure 101, the operator manually rotates the knob portion of the knob bolt 106, causing the screw to gradually tighten and press against the forklift tooth 2. The friction generated by the pressure between the screw and the forklift tooth 2 tightly fixes the base structure 101 and the forklift tooth 2, preventing them from sliding relative to each other.

[0071] This solution allows for tool-free fixing, with operators able to manually rotate the knob, simplifying the connection process between the tooling and the forklift and improving operational efficiency. The tightening of the knob bolts can be flexibly adjusted to accommodate forklift teeth 2 of different thicknesses or specifications, enhancing the tooling's versatility. Once fixed, it offers strong stability, capable of withstanding the shearing and tensile forces from the weight of the tooling and battery pack 3, preventing the tooling from detaching from the forklift teeth 2 during transport and ensuring operational safety.

[0072] This invention solves the problems of inconvenient and unreliable fixing of tooling to forklift gears in existing technologies. In existing technologies, some tooling lacks a dedicated fixing structure to the forklift gear, relying solely on friction for connection, which is prone to slippage; others use complex fixing connectors that require tools, making operation time-consuming and labor-intensive. The manual knob bolt design of this application balances ease of operation and reliable fixing, adapts to different forklift gear specifications, and improves the practicality of the tooling.

[0073] like Figure 1 As shown, first insert the forklift tooth 2 along the hole 104 on the transfer slide rail pallet fixture 1. Once it reaches the appropriate position, fix it to the forklift tooth 2 by manually turning the knob bolt 106 on the transfer slide rail pallet fixture 1 to prevent the transfer slide rail pallet fixture 1 from sliding off or falling off the forklift tooth 2 during the transfer process.

[0074] like Figure 2 The battery pack 3 is hooked onto the hook 302 of the gantry crane and then hoisted onto the transfer slide rail pallet fixture 1. The transfer slide rail pallet fixture 1 uses its front baffle 102, left baffle 103, right baffle 108, and quick-release locking structure 107 to limit the battery pack 3 in six directions (front, back, up, down, left, and right) to prevent it from slipping during transport. The locking structure 107 uses a quick-insert mechanism, meaning the locking mechanism can be quickly inserted and removed without tools, improving production efficiency. Figure 2 As shown in the enlarged diagram, the quick-release locking structure 107 can limit the fixing wedge 301 on the battery pack 3 in two directions (indicated by the arrows, the two directions of up and down).

[0075] like Figure 3 Insert the positioning pin 110 (a cylindrical or conical pin used for precise positioning) on ​​the transfer slide rail pallet tool 1 into the positioning hole 402 in the cabinet 4. At this time, the forklift is stationary, and the battery pack 3 is manually pushed onto the load-bearing guide rail 401 on the cabinet 4 to complete the assembly. See the boxed state. Figure 4 .

[0076] If battery pack 3 requires after-sales repair due to a malfunction, according to... Figure 4 To complete disassembly, simply pull the battery pack 3 onto the transfer slide rail tray fixture 1.

[0077] The design of the positioning pin 110 and the cabinet positioning hole 402 allows for quick and precise alignment of the tooling and the cabinet without the need for repeated fine-tuning of the forklift position. This simplifies the operation process and significantly shortens assembly time and improves production efficiency compared to the traditional method of relying on forklifts for alignment.

[0078] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
