Anti-swing electric single-beam crane adapted to hoist energy storage container

Abstract

The application discloses an anti-swing electric single-beam crane suitable for hoisting energy storage containers, and belongs to the technical field of hoisting energy storage containers. The anti-swing electric single-beam crane comprises an I-beam main beam, a running trolley sliding along the length direction of the I-beam main beam, and an electric hoist hoisted at the bottom of the running trolley. The steel wire rope cooperates with the chain belt of the electric hoist and the suspension hook at the bottom of the electric hoist to form a complete closed loop constraint. The vertical limiting action of the first fixed pulley ensures that the steel wire rope and the suspension hook are on the same vertical line. The winding mechanism maintains the steel wire rope in a tensioned state throughout the process. In this way, the top suspension and the bottom vertical tension of the hoisted battery module are bidirectionally constrained. In combination with the adaptive guidance of the guide mechanism, the installation plate can be synchronously followed during the movement of the hoisted object, so that the device can reduce the swing amplitude during the load transfer process, significantly improve the stability of hoisting and transferring, and improve the overall assembly efficiency of the energy storage container.

Description

Technical Field

[0001] This invention relates to an electric single-girder crane, and more particularly to an anti-sway electric single-girder crane adapted for lifting energy storage containers, belonging to the field of energy storage container lifting technology. Background Technology

[0002] During the assembly process inside energy storage containers, due to the generally large weight of the battery modules and the limited working space inside the containers, electric single-girder cranes are commonly used in the industry for lifting and transferring the battery modules. This type of equipment is flexible and suitable for the limited space inside the container, and has become the mainstream lifting equipment for energy storage container assembly.

[0003] However, during the actual hoisting process, the battery module is always suspended. It is easily subjected to large-scale swaying due to the impact of the crane's lifting, traveling, starting and stopping, and the load inertia. Even with the use of a multi-chain belt hoisting mechanism, the swaying amplitude can only be reduced slightly. The effect of suppressing swaying in the suspended state is not ideal. The shaking of the battery pack not only affects the assembly accuracy but also reduces the overall assembly efficiency of the energy storage container.

[0004] To address this issue, an anti-sway electric single-girder crane adapted for lifting energy storage containers was designed. Summary of the Invention

[0005] The main objective of this invention is to provide an anti-sway electric single-girder crane adapted for lifting energy storage containers. It achieves a complete closed-loop constraint through a steel wire rope, electric hoist chain, and suspension hook at the bottom of the electric hoist. The vertical limiting effect of the first fixed pulley ensures that the steel wire rope and suspension hook are on the same vertical line. A winding mechanism maintains the steel wire rope under tension throughout the process, thus achieving bidirectional constraint of top suspension and bottom vertical tension for the lifted battery module. Simultaneously, with the matching guidance mechanism, the mounting plate moves synchronously during the movement of the lifted object, reducing the sway amplitude during load transfer and significantly improving lifting performance. The system improves the stability of transport and enhances the overall assembly efficiency of the energy storage container. By setting up a telescopic mechanism composed of components such as chutes, sliding plates, second fixed pulleys, adjusting screws, threaded holes, and adjusting blocks, the fitting range of the closed loop formed by the wire rope and chain can be flexibly adjusted according to the external dimensions of the battery module to be lifted. This avoids the squeezing interference of the wire rope and chain on the side of the battery module, and always maintains the vertical limit state of the wire rope at the first fixed pulley. This ensures that the anti-sway effect of bidirectional tension is not affected by changes in load size, making the equipment compatible with the lifting operations of different models and specifications of energy storage battery modules, greatly improving the versatility and practical value of the equipment.

The pawl and the ratchet engage in a one-way meshing cooperation to achieve one-way self-locking and limiting of the drum.

[0009] Preferably, the telescopic mechanism includes a slide groove, a slide plate, a second fixed pulley, and an adjusting screw. The slide groove is opened horizontally on the end face of the mounting plate. The slide plate is slidably assembled inside the slide groove.

[0010] Preferably, the end of the slide plate near the adjusting screw has a threaded hole that matches the adjusting screw, and the threaded hole is located at the center of the end of the slide plate.

[0011] Preferably, the end of the adjusting screw away from the slide plate extends to the outside of the mounting plate, and an adjusting block is fixed to the end of the adjusting screw, with anti-slip texture provided on the outer side wall of the adjusting block.

[0012] Preferably, the guiding mechanism includes a rectangular steel pipe, a sealing end plate, a straight guide groove, a disassembly port, a sliding vertical rod, and guide wheels. The rectangular steel pipe is fixed to the inner bottom of the energy storage container, and the rectangular steel pipe is parallel to the length direction of the I-beam main beam. Both ends of the rectangular steel pipe are fixed with sealing end plates. A straight guide groove is opened at the top of the rectangular steel pipe along its length direction.

[0015] Preferably, the inner bottom of the energy storage container is provided with a groove that fits the rectangular steel tube, the rectangular steel tube is located inside the groove, and the depth of the groove is the same as the height of the rectangular steel tube.

[0016] The beneficial effects of this invention are as follows: This invention provides an anti-sway electric single-girder crane adapted for lifting energy storage containers. It forms a complete closed-loop constraint through a steel wire rope, the chain of an electric hoist, and a suspension hook at the bottom of the electric hoist. The vertical limiting effect of a first fixed pulley ensures that the steel wire rope and the suspension hook are on the same vertical line. A winding mechanism maintains the steel wire rope under tension throughout the process, thus achieving bidirectional constraint of top suspension and bottom vertical tension on the battery module. Simultaneously, with the matching guidance mechanism, the mounting plate moves synchronously during the movement of the lifted object. This reduces the sway amplitude during load transfer, significantly improving the stability of lifting and transporting, and enhancing the overall assembly efficiency of the energy storage container. By setting up a telescopic mechanism composed of components such as a slide, slide plate, second fixed pulley, adjusting screw, threaded hole, and adjusting block, the fitting range of the closed loop formed by the wire rope and chain can be flexibly adjusted according to the external dimensions of the battery module to be hoisted. This avoids the wire rope and chain from squeezing and interfering with the sides of the battery module, and can always maintain the vertical limit state of the wire rope at the first fixed pulley. This ensures that the anti-sway effect of bidirectional tension is not affected by changes in load size, making the equipment compatible with hoisting operations of different models and specifications of energy storage battery modules, greatly improving the equipment's versatility and practical value.

[0019] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0020] like Figures 1-9 As shown, this embodiment provides an anti-sway electric single-girder crane adapted for lifting energy storage containers, including an I-beam main beam 1, a traveling trolley 2 that slides along the length of the I-beam main beam 1, and an electric hoist 3 that is installed at the bottom of the traveling trolley 2. The lifting output end of the electric hoist 3 is provided with a chain, and the end of the chain is provided with a suspension hook. An installation plate 7 is located directly below the electric hoist 3. A first fixed pulley 8 is rotatably mounted on the top of the installation plate 7. A steel wire rope 4 is wound in the groove of the first fixed pulley 8. A winding mechanism 5 is installed at one end of the steel wire rope 4. A pull-down hook 6 connected to the bottom of the goods is provided on the winding mechanism 5. The pull-down hook 6 and the suspension hook are symmetrically connected to the bottom and top of the goods. During the hoisting process, the chain belt drives the suspension hook to lift the battery module upward. At the same time, the winding mechanism 5 is operated to tighten the steel wire rope 4, so that the steel wire rope 4 is kept taut throughout the process. With the help of the vertical limiting effect of the first fixed pulley 8 at the center of the top of the installation plate 7, the axis of the steel wire rope 4 and the center of the suspension hook are on the same vertical line, realizing the two-way constraint of the battery module being suspended at the top and vertically tightened at the bottom. A connecting hook 9 is fixed to the end of the wire rope 4 away from the winding mechanism 5. The connecting hook 9 is hung on the chain at the bottom of the electric hoist 3. The wire rope 4 forms a closed loop constraint through the pull-down hook 6, the connecting hook 9, the goods, the chain on the electric hoist 3, and the suspension hook. Before operation, the suspension hook is connected to the top lifting point of the battery module, and the pull-down hook 6 is connected to the corresponding lifting point at the bottom of the battery module, so that the suspension hook and the pull-down hook 6 are connected in a symmetrical state. Then, the connecting hook 9 is engaged and hung on the chain at the bottom of the electric hoist 3. At this time, the wire rope 4, together with the chain and suspension hook of the electric hoist 3, forms a complete closed loop constraint structure with the battery module through the pull-down hook 6, the connecting hook 9, and the wire rope 4. The mounting plate 7 is provided with a telescopic mechanism 10 on its side. The wire rope 4 is wrapped around the telescopic mechanism 10. The telescopic mechanism 10 is used to adjust the fitting size and expand the fitting range of the closed loop formed by the wire rope 4 and the chain belt to adapt to the hoisting requirements of battery modules of different specifications. The bottom of the mounting plate 7 is provided with a guide mechanism 11, which is used to limit the horizontal movement of the mounting plate 7 and guide the mounting plate 7 to move synchronously with the cargo. When the trolley 2 slides along the I-beam main beam 1 and drives the battery module to move horizontally, the guide mechanism 11 can guide the mounting plate 7 to move synchronously with the battery module, so as to avoid the battery module from swaying significantly due to the impact of starting and stopping during lifting and walking and inertia.

[0021] In this embodiment, the winding mechanism 5 includes a winding box 501, a drum 502, a box cover 503, a shaft 504, a hand crank 505, and a locking assembly. The drum 502 is rotatably mounted inside the winding box 501. The winding box 501 serves as the supporting base of the winding mechanism 5, providing installation and protection space for the internal components. The end of the wire rope 4 slides into the inside of the winding box 501 and is fixedly connected to the drum 502. The pull-down hook 6 is fixed to the outer wall of the winding box 501 for connection with the bottom of the battery module. The lifting points are stably connected; the cover 503 is fixed to the end face of the take-up box 501, forming an axial limit on the drum 502 to prevent the drum 502 from coming out of the take-up box 501 during rotation; the shaft 504 is coaxially fixed to one end of the drum 502, the shaft 504 passes through the cover 503 and extends to the outside of the cover 503, the hand crank 505 is fixed to the end of the shaft 504 away from the drum 502, and the locking assembly is located on the outside of the cover 503 for circumferential locking and positioning of the shaft 504.

[0022] During operation, the operator rotates the hand crank 505, which drives the shaft 504 to rotate circumferentially. The shaft 504 simultaneously drives the drum 502 to rotate within the winding box 501, thereby achieving the winding or unwinding of the wire rope 4. This allows for precise adjustment of the tension of the wire rope 4, ensuring that the wire rope 4 remains taut throughout the lifting and transport of the battery module. The locking component located on the outside of the box cover 503 can circumferentially lock and position the shaft 504 after the wire rope 4 is tensioned to the correct position, preventing the drum 502 from rotating uncontrollably in the opposite direction and avoiding the problem of the wire rope 4 becoming loose and unsuccessful, thus ensuring the continuous and stable bidirectional constraint effect.

[0023] In this embodiment, the locking assembly includes a ratchet 506 and a pawl 507. The ratchet 506 is coaxially fixedly mounted on the shaft 504 and rotates synchronously with the shaft 504. The pawl 507 is rotatably mounted on the outer side wall of the cover 503. The pawl 507 and the ratchet 506 engage in a one-way meshing cooperation to achieve a one-way self-locking limit on the drum 502.

[0024] When the operator turns the hand crank 505 to wind the wire rope 4, the shaft 504 drives the ratchet 506 to rotate in the forward direction. The teeth of the ratchet 506 slide over the end of the pawl 507. The pawl 507 does not restrict the forward rotation of the ratchet 506, ensuring that the winding operation of the wire rope 4 is completed smoothly. When the wire rope 4 is wound to the tensioned state, the weight of the battery module will apply a reverse rotational pulling force to the drum 502 through the pull hook 6 and the wire rope 4. At this time, the pawl 507 is engaged in the tooth groove of the ratchet 506, preventing the ratchet 506 from rotating in the reverse direction. This, in turn, forms a one-way self-locking limit on the drum 502 through the shaft 504, preventing the drum 502 from loosening the rope in the reverse direction. The tension of the wire rope 4 is maintained throughout the process, ensuring that the anti-sway effect of the two-way constraint is continuously effective.

[0025] In this embodiment, the telescopic mechanism 10 includes a slide groove 1001, a slide plate 1002, a second fixed pulley 1003, and an adjusting screw 1004. The slide groove 1001 is opened horizontally on the end face of the mounting plate 7 to provide precise sliding guidance and limiting for the slide plate 1002. The slide plate 1002 is slidably fitted inside the slide groove 1001. The second fixed pulley 1003 is rotatably mounted on the top of the slide plate 1002. The steel wire rope 4 is wound around the wheel groove at the bottom of the second fixed pulley 1003. The adjusting screw 1004 is rotatably mounted on the end of the mounting plate 7 away from the extension direction of the slide plate 1002, and the adjusting screw 1004 is threadedly connected to the slide plate 1002.

[0026] When it is necessary to adjust the adaptation size of the closed-loop constraint, rotate the adjusting screw 1004, and drive the slide plate 1002 to slide horizontally in a straight line along the slide groove 1001 through the threaded transmission. The slide plate 1002 drives the second fixed pulley 1003 to move horizontally in sync, changing the winding path and lateral span of the wire rope 4, thereby adjusting the closed-loop size formed by the wire rope 4 and the chain belt to adapt to battery modules of different widths and shapes, avoiding interference between the wire rope 4 and the side wall of the battery module, while ensuring that the vertical limit state of the wire rope 4 at the first fixed pulley 8 is not affected, ensuring a stable anti-sway effect when hoisting loads of different specifications.

[0027] In this embodiment, the end of the slide plate 1002 near the adjusting screw 1004 is provided with a threaded hole 1005 that is adapted to the adjusting screw 1004. When the adjusting screw 1004 rotates, the external thread of the adjusting screw 1004 and the internal thread of the threaded hole 1005 form a stable threaded transmission pair, which converts the circumferential rotation of the adjusting screw 1004 into the horizontal linear movement of the slide plate 1002. The threaded hole 1005 is located at the center of the end of the slide plate 1002, which can ensure that the slide plate 1002 is subjected to uniform force and avoid the problems of deflection and jamming when the slide plate 1002 slides in the slide groove 1001.

[0028] In this embodiment, the end of the adjusting screw 1004 away from the slide plate 1002 extends to the outside of the mounting plate 7, and the end of the adjusting screw 1004 is fixed with an adjusting block 1006, and the outer side wall of the adjusting block 1006 is provided with anti-slip texture.

[0029] When adjusting the size, the operator can directly hold the adjusting block 1006 and rotate the adjusting screw 1004. The anti-slip texture increases the friction between the hand and the adjusting block 1006, preventing slippage during rotation and making the adjustment operation more effortless and convenient.

[0030] In this embodiment, the guiding mechanism 11 includes a rectangular steel pipe 1101, a sealing end plate 1102, a straight guide groove 1103, a disassembly port 1104, a sliding vertical rod 1105, and a guide wheel 1106. The rectangular steel pipe 1101 is fixed to the inner bottom of the energy storage container, and the rectangular steel pipe 1101 is parallel to the length direction of the I-beam main beam 1, providing a stable straight reference for horizontal guidance. Both ends of the rectangular steel pipe 1101 are fixed with sealing end plates 1102, and the top of the rectangular steel pipe 1101 is along its length direction. A linear guide groove 1103 is provided, and the top two ends of the rectangular steel tube 1101 are provided with disassembly and assembly ports 1104 that communicate with the linear guide groove 1103, so as to facilitate the quick installation and disassembly of the sliding vertical rod 1105. The sliding vertical rod 1105 is slidably set inside the linear guide groove 1103. The top of the sliding vertical rod 1105 is fixedly connected to the bottom of the mounting plate 7. Guide wheels 1106 are rotatably installed on both sides of the bottom of the sliding vertical rod 1105. The guide wheels 1106 roll and fit against the inner top wall of the rectangular steel tube 1101.

[0031] When the mounting plate 7 moves horizontally with the battery module, the sliding vertical rod 1105 slides synchronously along the linear guide groove 1103. The linear guide groove 1103 forms a horizontal limit on the sliding vertical rod 1105, preventing the mounting plate 7 from shifting laterally or longitudinally, ensuring that the mounting plate 7 moves synchronously with the battery module. At the same time, the guide wheel 1106 rolls on the inner top wall of the rectangular steel tube 1101, converting sliding friction into rolling friction, greatly reducing the moving resistance, making the following of the mounting plate 7 smoother, avoiding the problem of jamming or lag causing the wire rope 4 to fail to maintain tension, and further improving the stability of anti-swaying.

[0032] In this embodiment, the connecting hook 9 and the chain of the electric hoist 3 are detachably snap-fit ​​connected, which can be quickly installed and disassembled according to the needs of hoisting operations, adapting to different hoisting scenarios. The hooking part of the connecting hook 9 is equipped with an anti-detachment buckle to prevent the connecting hook 9 from accidentally detaching from the chain, ensuring the integrity of the closed-loop constraint structure, avoiding the loss of tension constraint of the wire rope 4 due to connection detachment, and eliminating safety hazards in hoisting operations.

[0033] In this embodiment, the first fixed pulley 8 is fixedly installed at the top center of the mounting plate 7. The center of the first fixed pulley 8 and the center of the suspension hook at the end of the electric hoist 3 are on the same vertical line, and the axis of the wire rope 4 passing through the first fixed pulley 8 coincides with the vertical line.

[0034] This ensures that the downward tension force applied by the steel wire rope 4 to the battery module and the upward lifting force applied by the chain belt to the battery module through the suspension hook always act on the same vertical line, forming a coaxial bidirectional tension constraint. This prevents the generation of lateral force due to eccentric tension, fundamentally avoiding the swaying of the battery module due to uneven force, and maximizing the anti-sway effect.

[0035] In this embodiment, the inner bottom of the energy storage container is provided with a groove that is adapted to the rectangular steel pipe 1101. The rectangular steel pipe 1101 is located inside the groove, and the depth of the groove is the same as the height of the rectangular steel pipe 1101.

[0036] The installation method allows the top surface of the rectangular steel tube 1101 to remain flush with the inner bottom surface of the energy storage container, avoiding the rectangular steel tube 1101 from protruding and forming obstacles, and not affecting the installation and transfer of other equipment inside the energy storage container.

[0037] First, the I-beam main beam 1 is fixedly installed at the top preset position inside the energy storage container. The running trolley 2 is then assembled on the I-beam main beam 1, completing the fixed assembly of the electric hoist 3 and the running trolley 2. The operation is then adjusted to ensure that the running trolley 2 can drive the electric hoist 3 to slide smoothly along the length of the I-beam main beam 1. A rectangular steel pipe 1101 is embedded in the preset groove at the bottom inside the energy storage container. The position is corrected so that the rectangular steel pipe 1101 is parallel to the I-beam main beam 1. End plates 1102 are fixed at both ends of the rectangular steel pipe 1101. The sliding vertical rod 1105 is inserted into the linear guide groove 1103 through the disassembly port 1104 at the end of the rectangular steel pipe 1101, so that the guide wheel 1106 is stably attached to the inner top wall of the rectangular steel pipe 1101. Then, the top of the sliding vertical rod 1105 is fixedly connected to the bottom of the mounting plate 7, completing the assembly of the guide mechanism 11 and the mounting plate 7, providing a stable synchronous guide foundation for subsequent hoisting operations.

[0038] Based on the external dimensions of the battery module to be hoisted, the closed-loop constraint dimensions are adjusted to match: the operator holds the adjusting block 1006 and rotates the adjusting screw 1004. Through the threaded transmission between the adjusting screw 1004 and the threaded hole 1005, the sliding plate 1002 is driven to slide horizontally along the slide groove 1001. The horizontal position of the second fixed pulley 1003 is adjusted, and the winding span of the wire rope 4 is changed so that the closed-loop constraint range formed by the wire rope 4 and the chain belt matches the external dimensions of the battery module. This ensures that the wire rope 4 will not squeeze or interfere with the side wall of the battery module, and also ensures that the wire rope 4 winding around the first fixed pulley 8 always remains vertical, preparing for subsequent bidirectional constraint anti-swaying.

[0039] First, attach and fix the suspension hook at the end of the chain of the electric hoist 3 to the top suspension point of the battery module. Then, attach and fix the pull-down hook 6 on the winding mechanism 5 to the bottom of the battery module at a position symmetrical to the top suspension point. Next, engage and attach the connecting hook 9 at the end of the wire rope 4 to the chain at the bottom of the electric hoist 3, and fasten the anti-detachment buckle of the connecting hook 9 to complete the connection of the closed-loop constraint structure. At this time, the wire rope 4 passes through the second fixed pulley 1003 and the first fixed pulley 8 in sequence, forming a complete closed-loop circuit through the connecting hook 9, the chain of the electric hoist 3, the suspension hook, the battery module, the pull-down hook 6, and the winding mechanism 5.

[0040] The operator turns the hand crank 505, which drives the drum 502 to rotate and wind up the wire rope 4 through the shaft 504, keeping the wire rope 4 taut throughout the process. Once the tension is in place, the pawl 507 engages with the ratchet 506 in one direction, forming a self-locking limit on the drum 502 to prevent the wire rope 4 from slackening, thus completing all preparations before hoisting.

[0041] Start the electric hoist 3, which drives the chain belt to wind up, lifting the battery module vertically upwards via the suspension hook. During the lifting process, the wire rope 4 within the closed-loop constraint remains taut. The first fixed pulley 8 ensures that the wire rope 4 and the suspension hook are on the same vertical line. The upward pulling force of the chain belt and the downward tension force of the wire rope 4 form a coaxial bidirectional tension constraint, counteracting the vertical shaking and swaying tendency generated during the lifting and stopping of the battery module, allowing the battery module to complete the lifting action smoothly. After lifting to the preset installation height, the electric hoist 3 stops running, maintaining the suspension height of the battery module.

[0042] The drive trolley 2 slides along the length of the I-beam main beam 1, driving the electric hoist 3 and the battery module as a whole to move horizontally towards the installation position. During the horizontal movement, the battery module drives the mounting plate 7 to move synchronously through the tensioned steel wire rope 4. The sliding vertical rod 1105 at the bottom of the mounting plate 7 slides synchronously along the straight guide groove 1103 of the rectangular steel pipe 1101. The guide wheel 1106 rolls in the rectangular steel pipe 1101 to reduce the moving resistance. The straight guide groove 1103 forms a horizontal limit on the sliding vertical rod 1105 to prevent the mounting plate 7 from deviating horizontally. In turn, the tensioned steel wire rope 4 forms a horizontal swing constraint on the battery module, suppressing the large swing caused by the horizontal start-stop impact and load inertia of the battery module, ensuring that the battery module is smoothly and accurately transported to the top of the target installation position.

[0043] After the battery module is transferred to its position, start the electric hoist 3 to release the chain, causing the battery module to fall vertically downwards. During the descent of the battery module, the overall stroke of the closed-loop constraint can be synchronously adapted with the release of the chain, thus ensuring that the wire rope 4 remains taut throughout the descent. After the battery module falls to the designated position, pull the pawl 507 to disengage it from the ratchet 506, turn the hand crank 505 to release the wire rope 4, disconnect the pull-down hook 6 from the bottom of the battery module, then disconnect the suspension hook from the top of the battery module, and finally open the anti-detachment buckle of the connecting hook 9 and remove the connecting hook 9 from the chain of the electric hoist 3, completing the single battery module hoisting operation.

[0044] When it is necessary to hoist battery modules of different models and specifications, there is no need to disassemble the entire machine structure. Simply rotate the adjusting block 1006 again and adjust the position of the sliding plate 1002 and the second fixed pulley 1003 by adjusting the adjusting screw 1004. This allows for quick adjustment of the adaptation range of the closed-loop constraint. Repeat the above hoisting process to complete the hoisting operation of battery modules of different specifications, greatly improving the versatility of the equipment and the overall assembly efficiency of the energy storage container.
