Description

Technical Field

[0001] This invention relates to the field of battery hoisting technology, specifically to a battery swapping hoisting device for electric ships. Background Technology

[0002] With the rapid development of the new energy ship industry, electric ships, with their advantages of zero emissions and low noise, are gradually becoming an important development direction for water transportation. As the core power source of electric ships, the battery's replacement efficiency and the safety during the replacement process directly affect the ship's operating efficiency and operating costs. Currently, battery replacement for electric ships mostly relies on hoisting equipment.

[0003] Battery swapping for electric vessels is mostly carried out in open ports. During the hoisting process, the steel cable is easily affected by external factors such as wind force, battery lifting inertia, and slight swaying of the ship, resulting in irregular swaying. Existing hoisting devices often use a single damping structure for adaptive anti-swaying mechanisms, such as fixed friction plates or ordinary springs for vibration reduction. This can only attenuate swaying of a specific amplitude. Under small swaying conditions, the swaying kinetic energy of the steel cable is weak, and the fixed damping is prone to over-damping. Excessive damping force and high-frequency small swaying will resonate, leading to a decrease in the positioning accuracy of the clamping parts and prolonging the battery swapping preparation time. Under large swaying conditions, the kinetic energy of the steel cable is large, and the fixed damping force may not be able to meet the requirements at all. The undissipated kinetic energy forms a reciprocating swing, which greatly increases the risk of the battery colliding with the dock or ship. At the same time, the instantaneous impact load is directly transmitted to core components such as the gantry and transmission rod, which can easily cause structural damage such as weld cracks and rod bending. Summary of the Invention

A contact head is slidably connected inside the buffer. An inner spring is fixedly connected to the tail of the contact head, and the other end of the inner spring is connected to the inside of the buffer.

[0007] Preferably, the pressure plate has through holes on both sides, and an outward pusher corresponding to the through hole is fixedly connected inside the sleeve. The outward pusher has a first plane and a second plane. A pressing spring is provided inside the sleeve, and the pressing spring contacts the outer wall of the pressure plate. Friction strips are fixedly connected to both sides of the sleeve.

[0008] Preferably, the winding lubrication mechanism includes a transmission rod rotatably connected inside the receiving cavity, a winding roller fixedly connected to the transmission rod, a drive motor provided at the end of the transmission rod, three winding rollers arranged in parallel, two of which are wound with steel cables, and the other winding roller is wound with an auxiliary steel cable. The steel cable and the auxiliary steel cable pass through corresponding amplitude control rings respectively. A cam is rotatably sleeved on the outer wall of the transmission rod, and multiple baffles are rotatably connected to the cam. A pressure spring is fixedly connected to the outer wall of each of the multiple baffles, and the other end of the pressure spring is connected to the inner wall of the cam. A gear plate is fixedly connected to the outer wall of the transmission rod, and the baffles contact the outer wall of the gear plate.

[0009] Preferably, a liquid storage tank is fixedly connected to both sides of the receiving cavity, a spray nozzle is fixedly connected to the outer wall of the liquid storage tank, a suction pipe is provided between the spray nozzle and the liquid storage tank, a push rod is slidably connected inside the spray nozzle, a return spring is sleeved on the outer wall of the push rod, a pressure plate is fixedly connected to the end of the push rod, a rigid pipe is connected to the end of the spray nozzle away from the push rod, a flexible tube is connected to the end of the rigid pipe, a collar is connected to the end of the flexible tube, the collar is fixedly connected to the amplitude control ring, the collar is hollow inside, multiple spray holes are opened on the collar, and a scraper is fixedly connected to the outer wall of the collar.

[0010] Preferably, the ends of the two steel cables are fixedly connected to a clamping member, and tension detectors are provided on both sides of the clamping member. A battery is clamped on the clamping member, and a breakage prevention mechanism is provided on the clamping member.

[0011] Preferably, the breakage prevention mechanism includes a slide rail formed on the clamping member, a protrusion slidably connected inside the slide rail, the protrusion being fixedly connected to the end of the auxiliary steel cable, side connectors provided on both sides of the protrusion, and an electric telescopic rod installed on both sides of the protrusion, the end of the electric telescopic rod being inserted into the interior of the side connector.

[0012] Preferably, tension springs are fixedly connected to the outer walls of the side connectors on both sides, and the end of the tension spring away from the side connector is connected to the inner wall of the slide rail.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up an adaptive anti-sway mechanism, efficient attenuation of swings of different amplitudes is achieved. When the steel cable and auxiliary steel cable generate small-amplitude high-frequency swaying, the amplitude control ring will drive the tie rod to move slightly, so that the abrasive contact head and the friction strip are in contact, forming basic friction. With the elastic potential energy conversion of the pressing spring, the kinetic energy generated by high-frequency micro-swaying can be quickly attenuated to stabilize the battery and ensure hoisting stability. When the steel cable and auxiliary steel cable swing significantly, the contact end of the buffer and the contact head will be in contact with the friction strip together, increasing the friction. This gradually increasing resistance design can continuously consume the swing kinetic energy, avoid the reciprocating swing caused by energy accumulation, and make the large-amplitude swing tend to be stable, fundamentally eliminating the risk of battery collision. At the same time, by installing GPS positioning modules and wireless signal transmission modules on the track, moving parts and clamping parts, and connecting to the port crane remote control system, the initial positioning of the clamping parts and the battery to be replaced in the battery swapping compartment can be completed quickly and accurately, improving hoisting efficiency.

[0014] 2. Through the structural cooperation of the toothed disc and the cam, lubricating oil can be supplied during the winding of the steel cable and auxiliary steel cable, and the lubricating oil supply can be stopped during the lowering of the steel cable and auxiliary steel cable. This avoids the ineffective consumption of lubricating oil during the lowering process. Compared with the traditional continuous lubrication method, it greatly saves the amount of lubricating oil used. At the same time, after the lubricating oil is evenly applied through the spray holes, the scraper can scrape and level the lubricating oil on the surface of the steel cable and auxiliary steel cable, forming a continuous oil film with uniform thickness and strong adhesion. This effectively isolates the surface of the steel cable and auxiliary steel cable from moisture, seawater salt spray and other acidic corrosive substances in the dock environment, thus extending the service life of the steel cable and auxiliary steel cable.

[0015] 3. When any steel cable breaks or the tension drops suddenly, the electric telescopic rod on the opposite side of the fault will quickly retract and release the limit. Through the instantaneous release of the tension spring preload, the cam is pulled to slide along the slide rail to the limit position, so that the auxiliary steel cable is quickly tensioned and instantly takes over the entire load of the steel cable on the fault side. Through this emergency mechanism, it can be ensured that the clamping parts are always horizontally balanced, effectively preventing the battery from tilting or falling due to the lack of force on one side, and improving the safety of hoisting.

A suction pipe is provided between the spray nozzle 12 and the liquid storage tank 11. A push rod 18 is slidably connected inside the spray nozzle 12.

[0024] The ends of the two steel cables 5 are fixedly connected to a clamping member 6. Tension detectors are provided on both sides of the clamping member 6. A battery 7 is clamped on the clamping member 6. A breakage prevention mechanism is provided on the clamping member 6.

[0025] In this embodiment, the entire lifting device uses the gantry frame 1 as the core load-bearing foundation. The boom 2 is connected to the gantry frame 1 through a sliding structure, and its position can be flexibly adjusted along the height direction of the gantry frame 1 to adapt to the battery swapping needs of different models of electric ships. The track 3 on the boom 2 provides a horizontal movement path for the moving part 4. The track 3, the moving part 4, and the clamping part 6 are all equipped with GPS positioning modules and wireless signal transmission modules. The positioning accuracy is ≤5cm, and the signal protocol is compatible with the port crane remote control system. The remote control system presets the three-dimensional coordinate parameters of the electric ship's battery swapping compartment. The operator sends movement commands through the touch interface to control the moving part 4 to slide precisely along the track 3. The clamping component 6 is initially positioned with the battery 7 to be replaced in the battery swapping compartment (this is existing technology and will not be elaborated further). After the initial positioning is completed, the drive motor will drive the transmission rod 15 to rotate. When the transmission rod 15 rotates, the three parallel winding rollers 48 fixed on the transmission rod 15 rotate synchronously. The winding rollers 48 on both sides are responsible for winding the steel cable 5, and the winding roller 48 in the middle winds the auxiliary steel cable 8. When the winding roller 48 rotates counterclockwise to release the steel cable 5 and the auxiliary steel cable 8, the steel cable 5 and the auxiliary steel cable 8 together drive the clamping component 6 below to descend. After the clamping component 6 accurately clamps the battery 7, the winding roller 48 retracts the steel cable 5 and the auxiliary steel cable 8 clockwise, realizing the smooth lifting of the battery 7.

[0026] When the transmission rod 15 rotates counterclockwise, it drives the parallel winding rollers 48 to rotate in the opposite direction, and the steel cable 5 and the auxiliary steel cable 8 are released synchronously. When the transmission rod 15 rotates counterclockwise, it drives the toothed disc 45 to rotate synchronously. At this time, the inclined part of the toothed disc 45 will continuously contact the baffle 47 connected to the cam 16. At this time, the baffle 47 only swings slightly and cannot drive the cam 16 to rotate. Therefore, the winding lubrication mechanism remains in standby state to avoid ineffective consumption of lubricating oil during the lowering process.

[0027] When the transmission rod 15 rotates clockwise, the winding roller 48 rotates synchronously, starting to wind up the steel cable 5 and the auxiliary steel cable 8, thereby lifting the battery 7. At this time, the right-angled edge of the gear disc 45 forms a rigid contact with the baffle 47. The axial thrust generated by the right-angled edge will drive the cam 16 to rotate synchronously with the transmission rod 15. During the rotation of the cam 16, the protruding structure on its edge will intermittently contact the pressure plate 19. Under the combined action of the protruding pressure and the elastic restoring force of the return spring 17, the push rod 18 inside the spray nozzle 12 will reciprocate intermittently within the spray nozzle 12. At this time, the lubricating oil inside the storage tank 11 will be drawn into the spray nozzle 1 through the suction pipe. 2. Inside, the lubricant is sprayed into the collar 14 through the hard pipe 9 and the soft pipe 13. Finally, it is applied to the surface of the steel cable 5 and the auxiliary steel cable 8 through multiple spray holes 40 on the collar 14, so as to achieve lubrication when the steel cable 5 and the auxiliary steel cable 8 are wound up. During the winding and movement of the steel cable 5 and the auxiliary steel cable 8, the scraper 39 scrapes and smooths the lubricant on the surface of the steel cable 5 and the auxiliary steel cable 8, forming a continuous oil film with uniform thickness and strong adhesion. By applying lubricant, the corrosive media such as moisture and seawater salt spray in the dock environment can be isolated, avoiding the corrosion of the steel cable 5 and the auxiliary steel cable 8 used by the water for a long time, and extending the service life of the steel cable 5 and the auxiliary steel cable 8.

[0028] During the lifting and transfer of battery 7 driven by steel cable 5 and auxiliary steel cable 8, irregular swaying is easily generated by external factors such as wind force and inertia. Since steel cable 5 and auxiliary steel cable 8 pass through the corresponding amplitude control ring 24, the swaying of steel cable 5 and auxiliary steel cable 8 will directly drive the amplitude control ring 24 to shift synchronously. When the amplitude control ring 24 shifts, the pull rod 22 will slide along the axis of sleeve 23. At the same time, the first universal ball head 21 and the second universal ball head 25 will rotate adaptively. When the pull rod 22 slides along the axis of sleeve 23, the pressure plate 30 fixedly connected to the end of the pull rod 22 will move synchronously with the pull rod 22, thereby squeezing the pressing spring 29 in sleeve 23. In this process, the pressing spring 29 converts the kinetic energy generated by the swaying of steel cable 5 and auxiliary steel cable 8 into elastic potential energy, realizing preliminary vibration reduction. Based on the difference in swaying amplitude, the adaptive anti-sway mechanism will start different stabilization modes.

[0029] When the steel cable 5 and the auxiliary steel cable 8 drive the amplitude control ring 24 to produce a small swing amplitude, the swaying kinetic energy is relatively weak, and the movement amplitude of the pull rod 22 in the sleeve 23 also decreases accordingly, only causing the pressure plate 30 to produce a small displacement. At this time, the outward pusher 28 fixed inside the sleeve 23 will pass through the through hole 32, allowing the first plane 27 to contact the roller 36. Under the lifting action of the first plane 27, the roller 36 pushes the buffer 34 to move towards the friction strip 31 on the side wall of the sleeve 23 until the contact head 37 inside the buffer 34 is in contact with the friction strip 31. Since the contact surfaces of the contact head 37 and the friction strip 31 are both made of frosted material, a stable friction force will be generated after the two are in contact. This friction force and the elastic potential energy released by the pressing spring 29 form a synergistic effect, which can quickly attenuate the high-frequency micro-sway of the steel cable 5 and the auxiliary steel cable 8, avoid the battery 7 from producing a small sway, and ensure the hoisting positioning accuracy.

[0030] If the steel cable 5 and the auxiliary steel cable 8 cause the amplitude control ring 24 to swing significantly, the swaying kinetic energy will increase significantly. The pull rod 22 will cause the pressure plate 30 to move more within the sleeve 23. At this time, the first plane 27 and the second plane 26 on the pusher 28 will contact the roller 36 one after the other. In the initial stage, the first plane 27 pushes the buffer 34 to move, so that the contact head 37 and the friction strip 31 are in contact to generate basic friction force, which, together with the pressing spring 29, buffers the initial impact. As the swing amplitude further increases, the pressure plate 30 continues to move, and the higher roller 36 on the pusher 28... The second plane 26 contacts the roller 36, and the greater lifting force pushes the buffer 34 to further squeeze the friction strip 31, so that the contact end of the buffer 34 and the contact head 37 are in contact with the friction strip 31. The friction is significantly increased compared to before. This gradually increasing resistance design can continuously consume the swinging kinetic energy of the steel cable 5 and the auxiliary steel cable 8 through friction, avoiding the back-and-forth swinging of the steel cable 5 and the auxiliary steel cable 8 due to energy accumulation. Ultimately, it achieves efficient attenuation of large swings and fundamentally eliminates the safety risk of the battery 7 colliding due to the shaking of the steel cable 5 and the auxiliary steel cable 8.

[0031] Example 2: Please refer to Figure 1 - Figure 14 This embodiment further describes Example 1. The breakage prevention mechanism includes a slide rail on the clamping member 6. A protrusion 43 is slidably connected inside the slide rail. The protrusion 43 is fixedly connected to the end of the auxiliary steel cable 8. Side connecting members 44 are provided on both sides of the protrusion 43. Electric telescopic rods 42 are installed on both sides of the protrusion 43. The end of the electric telescopic rod 42 is inserted into the interior of the side connecting member 44.

[0032] A tension spring 41 is fixedly connected to the outer wall of each side connector 44, and the end of the tension spring 41 away from the side connector 44 is connected to the inner wall of the slide rail.

[0033] In this embodiment, the lower end of the auxiliary steel cable 8 is rigidly connected to the protrusion 43. The protrusion 43 is embedded in the slide rail inside the clamping member 6. Under normal conditions, the auxiliary steel cable 8 maintains only a slight tension and does not participate in bearing the weight of the battery 7, avoiding fatigue wear caused by long-term stress and ensuring that it can play its maximum load-bearing capacity in emergencies. When the left steel cable 5 is used for a long time and metal fatigue causes it to break or the tension drops suddenly, the tension detector will feed back the fault signal to the controller within 50ms. The controller will immediately issue an action command. The left electric telescopic rod 42 will remain extended to maintain the positioning reference, while the right electric telescopic rod 42 will quickly retract (this is prior art and will not be elaborated on). Its telescopic end will disengage from the right side connector 44, releasing the right side of the protrusion 43. With the limit constraint, the pre-tension of the left tension spring 41 is released instantly, pulling the protrusion 43 to slide quickly along the slide rail to the left limit position. During this process, the auxiliary steel cable 8 quickly switches from a slightly relaxed state to a tense state, instantly taking over all the load lost by the left steel cable 5, keeping the clamping part 6 in a horizontal and balanced state, effectively preventing the battery 7 from tilting or falling due to the lack of force on one side. If the fault scenario switches to the breakage of the right steel cable 5 or a sudden drop in tension, the breakage prevention mechanism will activate the symmetrical emergency response process. The right electric telescopic rod 42 remains extended and positioned, while the left electric telescopic rod 42 quickly retracts to release the limit. The tension of the right tension spring 41 pulls the protrusion 43 to slide along the slide rail to the right limit position, and the auxiliary steel cable 8 is simultaneously tensioned to take over the load lost on the right side.

[0034] It should be noted that the hose 13 will swing with the amplitude control ring 24. At the same time, both the suction tube and the rigid tube 9 are equipped with one-way valves to ensure that the rigid tube 9 only sprays oil and the suction tube only sucks oil. The moving part 4 is provided with an inspection door. When the lubricating oil in the storage tank 11 is used up, the inspection door can be opened and then added through the addition port opened on it (not shown in the figure).
