Description

Technical Field

[0001] This invention relates to an integrated loading and unloading device for rail-mounted battery packs, which is applied to the process of loading and unloading battery packs into and out of watertight compartments of underwater vehicles, enabling rapid and stable loading and unloading of battery packs. Background Technology

[0002] The battery pack is the energy source for electrically powered underwater vehicles. As vehicles are increasingly designed for longer endurance and higher speeds, the size and weight of battery packs are becoming increasingly large due to limitations in battery technology. In most vehicles, the battery pack ranks among the heaviest and largest components, making its installation and removal from the bay particularly difficult. For ease of installation and removal, battery packs are currently mostly fixed inside the bay using guide rails. The weight of the battery pack and the impact during movement are primarily borne by the guide rails, leaving other structures unable to support the load. If the battery is subjected to internal compression or impact, it could potentially cause a battery safety accident. Therefore, specialized equipment is required for installing and removing batteries from the bay. Currently, due to the high precision of the guide rails, the docking of the battery pack with the housing is troublesome when installing the housing device. It requires repeated adjustments to the coaxiality of the housing and the battery pack, which is time-consuming. When installing the housing, the operator must hold the housing in place to prevent displacement. Moreover, the main structure is mostly made of steel and fixed with aluminum profile corner brackets. It is heavy and easily deformed after being fixed with aluminum profile corner brackets due to load-bearing capacity and natural aging. It is not easy to adjust and often has to be cut and then re-fixed with aluminum profile corner brackets. Summary of the Invention

[0003] To save time in aligning the loading and unloading compartments of rail-mounted battery packs, reduce manpower requirements, lower the weight of the loading device, and facilitate size adjustments, an integrated loading and unloading device suitable for rail-mounted battery packs is needed. This device features an integrated adjustable alignment structure, uses lightweight profiles and screw connections, is adjustable, allows for fast alignment, is lightweight, and is not easily deformed.

[0004] This invention discloses an integrated loading and unloading device for a rail-mounted battery pack, comprising: a battery rack and a housing frame. The battery rack includes: adjustable feet, support beams, battery rack crossbeams, battery rack longitudinal beams, and uprights. Two parallel battery rack longitudinal beams are fixed to two parallel battery rack crossbeams via aluminum profile corner brackets. The two battery rack longitudinal beams and two battery rack crossbeams form a rectangular battery frame. An upright is fixed to each of the four corners of the battery frame via aluminum profile corner brackets. Two battery rack longitudinal beams are fixed to the other end of each upright via aluminum profile corner brackets. Support beams perpendicular to the two battery rack crossbeams are installed at both ends of each support beam. An adjustable foot is installed at the bottom end of each support beam. The housing frame includes: housing frame longitudinal beams, adjustable feet, support beams, and housing frame crossbeams. Two parallel housing frame longitudinal beams are fixed to two parallel housing frame crossbeams via aluminum profile corner brackets, forming a rectangular housing frame. The frame consists of two battery frame crossbeams, each with a support beam perpendicular to it. Adjustable feet are mounted at the bottom of each support beam. The rectangular battery frame and the rectangular battery frame are fixed together by inter-frame connecting plates. Several guide rail adjustment slots are formed on the two battery frame longitudinal beams on the uprights. A transverse waist groove is formed on the adjustable guide rail, aligning with the guide rail adjustment slots. The adjustable guide rail is fixed to the guide rail adjustment slots with bolts. A battery stop bar perpendicular to the two battery frame longitudinal beams is fixed between them at one end of the battery frame. A stop frame is fixed at the end of the rectangular battery frame. Two symmetrical transverse adjustment slots are formed on each of the two battery frame longitudinal beams. Two inclined frame bases are fixed to the transverse adjustment slots with bolts. Four symmetrical inclined frame adjustment slots are formed on the inclined frame bases. Two inclined frames are fixed to the inclined frame adjustment slots with bolts.

[0005] The present invention provides an integrated loading and unloading device for applicable rail-mounted battery packs, wherein: it further includes: a rail test frame, which is a rectangular frame used to detect whether the rails of the compartment are on the same straight line as the adjustable rails.

[0006] The present invention provides an integrated loading and unloading device for applicable rail-mounted battery packs, wherein: a rail constraint bar is fixed on the adjustable rail.

[0007] The present invention provides an integrated loading and unloading device for applicable rail-mounted battery packs, wherein wool felt is fixed on both the stop frame and the inclined frame.

[0008] The present invention provides an integrated loading and unloading device for applicable rail-mounted battery packs, wherein the inclination angle of the inclined frame is 40° to 50°.

[0009] The present invention provides an integrated loading and unloading device for applicable rail-mounted battery packs, wherein: a battery belly beam parallel to the battery crossbeam is also installed between the two uprights.

[0010] The two frames can be aligned and connected with high precision and strength during assembly. The longitudinal beams of the battery rack are equipped with adjustable auxiliary guide rails made of multiple stainless steel plates, dividing the long auxiliary guide rail into shorter sections. This reduces manufacturing difficulty. The stainless steel plates are hard, rust-free, and have a good finish, preventing wear and tear on the auxiliary guide rails when the battery is being moved. Lubrication further reduces friction when the battery is being installed or removed from the compartment. The auxiliary guide rails are equipped with segmented guide rail constraint strips to constrain the lateral (width) movement of the battery. The spacing between the left and right auxiliary guide rails can be finely adjusted through the oblong holes in the auxiliary guide rails, facilitating alignment between the battery rack and the compartment guide slots. The compartment frame consists of four 45° inclined support frames fixed to the base by aluminum profile corner brackets, arranged in groups of two, one at the front and one at the back, collectively supporting the cylindrical compartment. The vertical and horizontal positions of the cylindrical compartment can be finely adjusted through the oblong holes at the bottom of the inclined support frames, facilitating centering and alignment. An L-shaped stop is installed at the end of the hull frame to effectively prevent the hull from moving backward under thrust. Wool felt is pasted on the inclined surface of the ramp support frame and the pressing surface of the stop to protect the hull surface and prevent crushing. The aluminum profile itself has grooves, and the fore-and-aft positions of the stop and ramp support frame can be adjusted according to the hull length. The device is equipped with a guide rail trial assembly frame of the same size as the battery pack guide rail. During use, the hull is first rolled and aligned using the trial assembly frame as a reference. After alignment, the battery pack is then loaded or unloaded from the hull, shortening the hull roll alignment adjustment time.

[0011] The beneficial effects of this patent are:

[0012] To save time on docking and alignment of rail-mounted battery packs and reduce manpower requirements for ease of use, this patent designs an integrated loading and unloading device suitable for rail-mounted battery packs. This patent efficiently utilizes pre-fabricated profiles and features multiple adjustable mechanisms for convenient loading and unloading of rail-mounted battery packs.

[0013] Its advantages include:

[0014] 1. The main frame of the device is constructed from the same type of aluminum profile and is fixed with bolts, eliminating the need for fixing with aluminum profile corner fittings, which improves processing efficiency and avoids deformation caused by fixing with aluminum profile corner fittings. The device itself is lightweight and easy to carry and transport.

[0015] 2. The support beam made of channel steel is equipped with adjustable feet, which makes it easy to adjust the levelness and stability of the device on different support surfaces, so that the battery pack can be installed and removed from the compartment smoothly and safely. The foot nuts are locked with double nuts to prevent loosening, one of which is directly fixed to the support beam through aluminum profile corner fittings, making it easier to adjust the feet.

[0016] 3. The lower longitudinal beams of the cabin frame and the lower longitudinal beams of the battery frame have long mating surfaces, and the two frames are fixed together by connecting plates. Based on the high straightness and flatness of the lower longitudinal beam profile, the alignment of the cabin frame and the battery frame can be guaranteed to be high. After being fixed together, the strength is high and it is not easy to lose alignment due to external forces.

[0017] 4. The four 45° inclined support frames of the cabin frame, which are fixed by aluminum profile corner brackets, are adjustable in position, making it easy to adjust the left-right and up-down position of the cabin. After simple installation, debugging and fixing, the cabin only needs to be placed on the cabin frame to complete the alignment with the battery rack. Then, only the horizontal roll of the cabin needs to be adjusted, which greatly shortens the time for adjustment and alignment.

[0018] 5. The battery rack guide rail has oblong holes, which can adjust the guide rail spacing and better restrain the left and right movement of the battery pack on the rack, which facilitates the quick alignment of the battery pack guide rail with the cabin guide groove during the battery pack loading and unloading process.

[0019] 6. The device is equipped with a guide rail test frame. First, use the lightweight guide rail test frame as a reference to adjust the roll of the cabin. After the roll is in place and the guide rail test frame can be smoothly installed out of the cabin, then push the battery pack out of the cabin. This avoids directly pushing the heavier battery pack for roll centering adjustment, which can save time for cabin roll alignment adjustment. Attached Figure Description

Two parallel battery rack longitudinal beams 4 are fixed to two parallel battery rack crossbeams 3 by aluminum profile corner fittings 18. The two battery rack longitudinal beams 4 and the two battery rack crossbeams 3 form a rectangular battery frame. A column 5 is fixed to each of the four corners of the battery frame by aluminum profile corner fittings 18. Two battery rack longitudinal beams 4 are fixed to the other end of the column 5 by aluminum profile corner fittings 18. A battery belly beam 23 parallel to the battery crossbeam 3 is also installed between the two columns 5. Support beams 2 perpendicular to the two battery rack crossbeams 3 are installed at both ends of the two battery rack crossbeams 3. An adjustable foot 1 is installed at the bottom end of each support beam 2. Several guide rail adjustment slots 19 are opened on the two battery rack longitudinal beams 4 on the column 5.

The adjustable guide rail 7 is fixed to the guide rail adjustment slots 19 by bolts. A guide rail constraint strip 8 is fixed on the adjustable guide rail 7. A battery stop strip 6 perpendicular to it is fixed between the two battery rack longitudinal beams 4 at one end of the battery frame.

[0028] The cabin frame 21 includes: cabin frame longitudinal beams 10, adjustable feet 1, support beams 2, and cabin frame crossbeams 14. Two parallel cabin frame longitudinal beams 10 are fixed to two parallel cabin frame crossbeams 14 by aluminum profile corner brackets 18, forming a rectangular cabin frame. Support beams 2 perpendicular to the two cabin frame crossbeams 14 are installed at both ends, and adjustable feet 1 are installed at the bottom end of each support beam 2. The rectangular battery frame and the rectangular cabin frame are fixed together by inter-frame connecting plates 15. The guide rail test assembly frame 9 is a rectangular frame, used to check whether the cabin guide rail is on the same straight line as the adjustable guide rail 7. Stop frames 13 are fixed at the ends of the rectangular cabin frame. Two symmetrical horizontal adjustment slots 16 are opened on the two longitudinal beams 10 of the cabin frame. Two inclined frame bases 11 are fixed to the horizontal adjustment slots 16 by bolts. Four symmetrical inclined frame adjustment slots 17 are opened on the inclined frame bases 11. Two inclined frames 12 are fixed to the inclined frame adjustment slots 17 by bolts. The inclination angle of the inclined frames 12 is 45°. Wool felt 22 is fixed on both the stop frames 13 and the inclined frames 12.

[0029] like Figure 2 As shown, the cabin is first placed on the cabin frame 21 of the device, and then the guide rail test frame 9 is placed as the reference for the cabin roll adjustment. When the cabin guide groove is aligned with the guide rail test frame 9, the battery pack can be manually installed or removed.

[0030] Adjust the spacing of the adjustable guide rails 7 of the battery rack according to the left and right play when the guide rail test frame 9 slides, so that the guide rail constraint strip 8 and the guide rail test frame 9 have a proper fit clearance, and then fix the battery stop strip 6; place the cabin on the cabin frame, adjust the position of the stop frame 13 so that the cabin can be raised and lowered easily and can be held in place by the stop frame 13; adjust the position of the inclined frame 12 on the inclined frame base 11 until the guide rail test frame 9 can slide smoothly into the cabin guide groove, then the installation and debugging of the integrated cabin loading and unloading device is completed.

[0031] When using the device to assemble the battery pack into the cabin, place the battery pack and cabin onto the battery rack 20 and cabin rack 21 of the device respectively. Then, using the guide rail test assembly frame 9 as a reference, adjust the cabin to roll until the guide rail test assembly frame 9 is aligned with the cabin guide groove. Then, remove the guide rail test assembly frame 9. At this time, the battery pack can be manually pushed into the cabin smoothly. The backward friction force on the cabin during installation will be offset by the stop frame 13.

[0032] When using the device to unload the battery pack from the cabin, place the cabin containing the battery pack on the cabin frame 21 of the device, and then adjust the cabin to roll horizontally with the guide rail test frame 9 as a reference until the guide rail test frame 9 is aligned with the cabin guide groove. Then, remove the guide rail test frame 9. At this time, the battery pack can be manually pulled out of the cabin smoothly. When unloading, the forward friction force on the cabin will be offset by the end face of the battery frame longitudinal beam 4 on the battery frame.
