Description

Technical Field

[0001] This application belongs to the field of energy supply box hoisting technology, and in particular relates to an energy supply box hoisting structure. Background Technology

[0002] Range-extended energy storage (REES) power supply boxes, as integrated mobile energy storage devices, typically consist of core components such as lithium iron phosphate batteries, a battery management system, an energy storage converter, a fire detection and gas extinguishing system, a temperature-controlled liquid cooling system, a diesel generator set, and a dispatch control system. These devices also have photovoltaic power generation interfaces and charging pile installation space, offering rich adaptability to pre-set scenarios, comprehensive protection functions, and excellent control performance. They can adapt to harsh power grid environments and are widely used in various scenarios such as peak shaving and valley filling, dynamic capacity expansion, and off-grid power supply. After the foundation construction is completed, the assembled power supply box needs to be hoisted onto the pre-set foundation for installation and fixation.

[0003] During the engineering design phase of the energy supply box, R&D personnel typically create a 3D model based on the theoretical layout of the internal components and calculate the theoretical center of gravity of the energy supply box. Based on this, they determine the arrangement of the lifting points on the box. In actual lifting operations, a crane is usually used in conjunction with slings, which are then connected to the pre-set lifting points for hoisting.

[0004] During actual hoisting, factors such as assembly tolerances during on-site assembly of internal components like battery modules, diesel generator sets, and converter cabinets, deviations between actual and theoretical weights of components, and inconsistencies between on-site assembly sequence and design models lead to discrepancies between the actual and designed center of gravity of the power supply box. When lifting according to the preset lifting points, this deviation can cause the box to tilt, resulting in instability and safety hazards. To address this issue, power supply box installation manuals typically require maintaining the box horizontally during hoisting to ensure stability and safety. However, under current operating conditions, operators usually adjust the sling length repeatedly, conducting multiple trial lifts to gradually correct the box's posture until it is level before proceeding with the final hoisting. This method is cumbersome, inefficient, and requires multiple trial lifts, increasing time costs and safety risks. Summary of the Invention

[0005] To address the shortcomings of the prior art, this application provides a power supply box hoisting structure to improve the hoisting efficiency and stability of the power supply box.

[0006] To achieve the above objectives, the present invention employs the following techniques: A power supply box hoisting structure, comprising: The load-bearing beam includes two parallel crossbeams and a longitudinal beam that is perpendicularly connected between the middle of the two crossbeams. The debugging component includes four sliders that slide along the length of the two crossbeams at both ends. The two sliders at the same end of the load-bearing beam are always arranged along the length of the longitudinal beam. The upper end of the slider extends above the load-bearing beam and the two sliders at the same end are positioned opposite each other on one side. The lower end of the slider extends below the load-bearing beam and is connected to a sling, the end of which is connected to a hook. The drive assembly includes two sets of linear mechanisms respectively located on both sides of the longitudinal beam. The two linear mechanisms are used to drive the two sliders at the same end of the load-bearing beam to move synchronously. The first locking assembly includes two mating blocks that slide along the length of the longitudinal beam, with the lower end of each mating block rotatably connected to a connecting rod; a guide rod slides through the middle of the longitudinal beam, and the other ends of the two connecting rods are rotatably connected to the lower end of the guide rod; the two connecting rods and the guide rod form a linkage mechanism to convert the lifting motion of the guide rod into the separating and closing motion of the two mating blocks; a lifting ring is provided at the upper end of the guide rod; a strip plate located above the load-bearing beam and arranged parallel to the crossbeam is connected to the upper end of the mating blocks, and one side of each end of the strip plate is used to abut against one side of two sliders on the adjacent crossbeam as the two mating blocks separate; The second locking assembly is used to fix the two mating blocks when the two sliders on the strip plate and the adjacent crossbeam are spaced at a predetermined distance.

[0007] The beneficial effects of this invention are as follows: 1. The hoisting structure drives the slider to slide along the crossbeam through the drive component, realizing stepless adjustment of the hoisting point position in the horizontal direction. The operator can remotely adjust the position of the two sliders at the same end according to the actual tilt direction of the power supply box during low-altitude trial hoisting. The attitude correction can be completed in a single trial hoisting process. Unlike the existing technology, there is no need for repeated trial hoisting and multiple adjustments of the sling length, which significantly improves hoisting efficiency and reduces the difficulty of operation and hoisting risk. 2. This technical solution integrates the main lifting point and the locking mechanism of the slider into one unit. During the actual lifting, the tension of the main hook on the guide rod is naturally converted into the separation driving force of the mating block, so that the strip plate and the slider automatically form a tight lock during the lifting process without additional operation. The lifting load is directly transmitted to the slider through the strip plate. The linear mechanism is not subjected to force during the lifting process, avoiding the problem of overload of the linear mechanism or displacement of the slider due to the lifting load, thus improving the safety and stability of the lifting.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0019] Example 1 This application provides an embodiment of a power supply box hoisting structure for use in... Figure 7 The power supply box 6 shown is hoisted. On both sides of the power supply box 6, a hoisting column 61 is vertically installed at each end near the bottom edge. The two hoisting columns 61 at the same end of the power supply box 6 are coaxially arranged. The specific position of the hoisting column 61 is determined according to the theoretical center of gravity of the power supply box 6.

[0020] like Figures 1-6 As shown, the hoisting structure includes: a load-bearing beam 1, a debugging component 2, a driving component 3, a first locking component 4, a second locking component 5, etc.

[0021] Among them, such as Figure 1 As shown, the load-bearing beam 1 serves as the supporting skeleton of the overall structure, including two parallel horizontal beams 11 and a vertical longitudinal beam 12 connected between the middle of the two horizontal beams 11. The two horizontal beams 11 and the longitudinal beam 12 together form an I-shaped frame structure, providing the installation foundation and load-bearing support for each component.

[0022] like Figure 1 and Figure 3 As shown, the debugging component 2 is used to connect the power supply box 6 and adjust the position of the suspension point. It includes four sliders 21, which slide along the length direction and are engaged at both ends of the two crossbeams 11. Specifically, each end of each crossbeam 11 is provided with a slider 21, and the two sliders 21 at the same end of the supporting beam 1 are always arranged along the length direction of the longitudinal beam 12, that is, the distance between the two sliders 21 at the same end of the supporting beam 1 and the longitudinal beam 12 is always equal and they move synchronously; the upper end of the slider 21 extends above the supporting beam 1, and the two sliders 21 at the same end are arranged opposite each other on one side; the lower end of the slider 21 extends below the supporting beam 1 and is connected in sequence with a sling 22 and a hook 23, and the four hooks 23 are used to directly hook the lifting column 61 of the power supply box 6; furthermore, strip holes can be opened through both ends of the crossbeam 11 along its thickness direction, and the strip holes are arranged along the length direction of the crossbeam 11. At the same time, the two ends of a pair of sliding rods are respectively connected to the two end walls of the strip holes, and the sliding rods are arranged along the length direction of the crossbeam 11; each slider 21 slides through the corresponding sliding rod.

[0023] like Figure 1 As shown, the drive assembly 3 is used to drive the slider 21 to slide along the crossbeam 11. It includes two sets of linear mechanisms 31 respectively set on both sides of the longitudinal beam 12 and two connecting rods 32. The connecting rods 32 are parallel to the longitudinal beam 12 and their two ends are respectively connected to the two sliders 21 at the same end of the bearing beam 1. Mounting plates 33 are fixedly provided on both sides of the longitudinal beam 12. The two linear mechanisms 31 are respectively fixed on the two mounting plates 33, and their movable ends face each other along the length of the crossbeam 11 and are connected to the corresponding connecting rods 32. Specifically, due to the requirement of the lifting structure for the flexibility of the drive mechanism, the linear mechanism 31 preferably adopts the form of a linear electric cylinder combined with a lithium battery pack. During operation, the two linear mechanisms 31 respectively drive the two sliders 21 at the same end of the bearing beam 1 to move synchronously, thereby changing the position of the sling 22 and the hook 23 in the horizontal direction.

[0024] like Figure 1 , Figure 2 , Figure 4As shown, the first locking assembly 4 is used to lock and fix the slider 21 after the slider 21 is adjusted to the correct position. It includes two mating blocks 41 that slide along the longitudinal beam 12. The two mating blocks 41 can slide towards each other or away from each other along the longitudinal beam 12. Specifically, strip holes can be opened at both ends of the longitudinal beam 12 along its thickness direction and arranged along the longitudinal beam 12. Slide rods are arranged in the strip holes along the longitudinal beam 12. The two mating blocks 41 slide through the corresponding slide rods. The lower end of each mating block 41 is rotatably connected to one end of a connecting rod 42. A guide rod 43 slides through the middle of the longitudinal beam 12. The other ends of the two connecting rods 42 are rotatably connected to the lower end of the guide rod 43. The rotation axes at both ends of the connecting rods 42 are arranged along the length of the crossbeam 11. Thus, the two connecting rods 42 and the guide rod 43 together constitute a linkage mechanism. This linkage mechanism is used to convert the lifting motion of the guide rod 43 into the separation and closing motion of the two mating blocks 41. Specifically, when the guide rod 43 is lifted upward, the lower ends of the two connecting rods 42 move upward accordingly, and their angles change, thereby pushing the two mating blocks 41 to separate from each other along the longitudinal beam 12; when the guide rod 43 is pressed downward, the two connecting rods 42 pull the two mating blocks 41 closer together.

[0025] like Figures 1-5 As shown, the upper end of the guide rod 43 is provided with a lifting ring 49 for connecting external lifting equipment, such as the main hook of a crane; the upper end of each mating block 41 is connected to a strip plate 44, which is located above the bearing beam 1 and arranged parallel to the crossbeam 11. One side of each end of the strip plate 44 faces the two sliders 21 on the adjacent crossbeam 11; when the two mating blocks 41 separate, the strip plate 44 moves with the mating blocks 41, and one side of each end of the strip plate 44 abuts against one side of the two sliders 21 on the adjacent crossbeam 11, thereby locking the two sliders 21 at the same end in the current sliding position; when the two mating blocks 41 come together, the strip plate 44 disengages from the abutment with the sliders 21 and releases the locking state.

[0026] like Figure 4 and Figure 6 As shown, the second locking component 5 is used to fix the two mating blocks 41 when the strip plate 44 and the two sliders 21 on the adjacent crossbeam 11 are spaced at a predetermined distance. That is, when it is not necessary to lock the sliders 21, the mating blocks 41 are locked at a certain position on the longitudinal beam 12 by the second locking component 5, so that the strip plate 44 is kept separated from the sliders 21, which facilitates the free sliding adjustment of the sliders 21.

[0027] The working principle of the hoisting structure will be explained below based on the above structure: Preparation stage: such as Figure 1 , Figure 3 , Figure 4 , Figure 6As shown, before the hoisting operation begins, the hoisting structure is in its initial state. At this time, the strip plate 44 on the two mating blocks 41 is spaced apart from the two sliders 21 on the adjacent crossbeam 11 by a predetermined distance, that is, the strip plate 44 and the slider 21 are kept separated. The second locking assembly 5 fixes the position of the mating block 41. At this time, the linkage mechanism composed of the two connecting rods 42 and the guide rod 43 is locked, and the mating block 41, the guide rod 43 and the connecting rod 42 remain relatively stationary.

[0028] Installation phase: such as Figure 5 and Figure 8 As shown, the operator hooks the main hook of an external lifting device, such as a crane, onto the lifting ring 49 at the upper end of the guide rod 43, lifting the entire load-bearing beam 1 and moving it above the power supply box 6. Since the second locking assembly 5 has locked the linkage mechanism, during the lifting and movement of the load-bearing beam 1, the mating block 41, the guide rod 43, and the connecting rod 42 remain relatively stationary, and the strip plate 44 remains separated from the slider 21, ensuring that the slider 21 can slide freely. Subsequently, the operator hooks each hook 23 in the debugging assembly 2 onto the lifting columns 61 at the bottom of both sides of the power supply box 6.

[0029] Trial Lifting Phase: After hooking is completed, the trial lifting phase begins. The crane drives the entire load-bearing beam 1 upward. During this period, the second locking assembly 5 will still fix the mating block 41, and the linkage mechanism will remain locked. The energy supply box 6 will be lifted to 10-15 cm off the ground. At this point, due to the deviation between the actual center of gravity and the design center of gravity of the energy supply box 6, the energy supply box 6 will tilt slightly. The operator remotely operates the two sets of linear mechanisms 31 of the drive assembly 3, respectively driving the two sliders 21 at the same end of the load-bearing beam 1 to move synchronously along the crossbeam 11, in order to adjust the relative position of the two hooks 23 at the same end in the length direction of the crossbeam 11. Since the hooks 23 are connected to the sliders 21 through the slings 22, the change in the position of the sliders 21 directly changes the suspension point position of the slings 22. The adjustment principle is as follows: When the power supply box 6 tilts, its tilt direction indicates that the center of gravity is biased to one side. The operator moves the two sliders 21 at the same end in the opposite direction of the tilt through the linear mechanism 31, causing the point of application of the resultant force of the sling 22 on the power supply box 6 to shift, thereby generating a torque opposite to the tilt direction, and gradually correcting the power supply box 6 to a horizontal state. The operator can continuously fine-tune the position of the sliders 21 according to the attitude feedback of the power supply box 6 until the power supply box 6 is restored to a horizontal state. This process does not require repeated trial lifting; only one sliding adjustment in a low-altitude state is needed to complete the attitude correction. After the power supply box 6 is leveled, the crane is used to lower the power supply box 6 to the ground. At this time, the operator releases the second locking component 5 from the locking of the mating block 41, allowing the linkage mechanism to regain its mobility, while keeping each hook 23 in the hooked state.

[0030] Formal hoisting stage: such as Figure 4 , Figure 5 , Figure 7, Figure 9 As shown, the crane's main hook lifts the guide rod 43 upwards relative to the crossbeam 11 and longitudinal beam 12 via the lifting ring 49. As the guide rod 43 rises, the lower ends of the two connecting rods 42 move upwards, pushing the two mating blocks 41 to separate along the longitudinal beam 12. The mating blocks 41 drive the strip plates 44 to move until the strip plates 44 are tightly abutted against one side of the two sliders 21 on the adjacent crossbeam 11. At this time, the linkage mechanism is locked by the first locking assembly 4 itself, meaning that the two mating blocks 41 remain separated while the guide rod 43 is under continuous tension. As the crane continues to lift, the main hook's tension... Force is transmitted to slider 21 through guide rod 43, connecting rod 42, mating block 41, and strip plate 44, and then drives the power supply box 6 to move upward as a whole through sling 22 and hook 23. During this process, the two sliders 21 are tightly pressed against strip plate 44 under the gravity of cross beam 11, longitudinal beam 12 and power supply box 6, thereby locking and fixing slider 21. This design can prevent the linear mechanism 31 from bearing the lifting load when the lifting is under force, and prevent the slider 21 from changing position due to overload of the linear mechanism 31, effectively improving the stability and safety of the lifting process.

[0031] Lifting completion stage: After the power supply box 6 is lifted and placed on the foundation, the operator removes the hook 23 to complete the lifting operation. Then, the operator separates the strip plate 44 and the corresponding slider 21 to a predetermined distance, and uses the second locking component 5 to relock the mating block 41, so that the device returns to its initial state, ready to lift the next power supply box 6.

[0032] The lifting structure drives the slider 21 to slide along the crossbeam 11 via the drive assembly 3, achieving stepless adjustment of the lifting point position in the horizontal direction. Operators can remotely adjust the positions of the two sliders 21 at the same end based on the actual tilt direction of the power supply box during low-altitude trial lifting, completing attitude correction during a single trial lift. This eliminates the need for repeated trial lifts and multiple adjustments of the sling length as required by existing technologies, significantly improving lifting efficiency and reducing operational difficulty and lifting risks. Simultaneously, this technical solution integrates the locking mechanism of the main lifting point and the slider 21 into one unit. During formal lifting, the tension of the main hook on the guide rod 43 naturally transforms into the separation driving force of the mating block 41, causing the strip plate 44 and the slider 21 to automatically form a tight lock during lifting, requiring no additional operation. Furthermore, the lifting load is directly transmitted to the slider 21 through the strip plate 44, and the linear mechanism 31 is not subjected to force during lifting, avoiding overload of the linear mechanism 31 or displacement of the slider 21 due to the lifting load, thus improving the safety and stability of the lifting operation.

[0033] Specifically, such as Figure 3As shown, the strip plate 44 has pressure teeth 45 evenly distributed on both ends facing the slider 21, and the corresponding two sliders 21 have elastic friction layers 46 attached to one side. When the strip plate 44 moves with the mating block 41 and presses the slider 21, the pressure teeth 45 are used to press into the elastic friction layers 46 to fix the slider 21. Preferably, the elastic friction layer 46 can be made of polyurethane, rubber or other materials with good elasticity and wear resistance, and is fixed to the surface of the slider 21 facing the strip plate 44. The pressure teeth 45 are arranged at intervals along the length of the strip plate 44, and their tips are conical or wedge-shaped. When the two mating blocks 41 During separation, the strip plate 44 moves toward the slider 21, and the pressure tooth 45 first contacts the elastic friction layer 46 and gradually presses into its interior. During this process, the elastic friction layer 46 undergoes elastic deformation, wrapping around and tightly adhering to the pressure tooth 45, forming a multi-point interlocking structure. Compared with simple planar contact, this structure has a larger contact area and higher frictional resistance, which can effectively resist the sliding tendency of the slider 21 under the action of hoisting load. At the same time, the elastic restoring force of the elastic friction layer 46 creates a continuous positive pressure between the pressure tooth 45 and the slider 21, further enhancing the stability of the locking.

[0034] Preferred, such as Figure 3 and Figure 5As shown, to further improve the stability and reliability of the slider 21 when locked, an installation groove 24 can be opened on one side of the slider 21 along the length of the longitudinal beam 12. A square hole 25 is opened through the bottom of the installation groove 24. A pressure block 26 is provided in the installation groove 24. One side of the pressure block 26 faces the strip plate 44, and the middle of the other side is provided with a strip block 27 that slides and fits in the square hole 25 along the length of the longitudinal beam 12. An elastic friction layer 46 is provided on the surface of the pressure block 26 facing the strip plate 44. The mounting groove 24 is provided with a pair of first helical springs 28 arranged along the length of the longitudinal beam 12 and located on both sides of the strip block 27. The two ends of the two first helical springs 28 are respectively connected to the bottom of the mounting groove 24 and the other side of the pressure block 26. The top surfaces of both ends of the two crossbeams 11 are vertically provided with strip-shaped pressure plates 18. The pressure plates 18 are arranged along the length of the crossbeams 11, and one side of the pressure plates 18 faces the other side of the corresponding slider 21. The end of the strip block 27 is also provided with an elastic friction layer 46, and the side of the pressure plate 18 facing the slider 21 is also provided with pressure teeth 45. When it is necessary to lock the slider 21, the guide rod 43 rises to drive the two mating blocks 41 to separate, and the strip plate 44 moves towards the slider 21. The pressure teeth 45 on the strip plate 44 first contact the elastic friction layer 46 on the pressure block 26 and gradually press into it. During this process, the strip plate 44 applies a pushing force to the pressure block 26, overcoming the elastic force of the first helical spring 28, and pushes the pressure block 26 into the mounting groove 24. When the pressure block 26 moves, the strip block 27 on its back extends along the square hole 25 to the other side of the slider 21 until the elastic end of the strip block 27 reaches the other side. The friction layer 46 contacts and presses against the pressure teeth 45 on the pressure plate 18. At this time, the slider 21 is subjected to bidirectional clamping: on one side, the strip plate 44 provides locking force through the engagement of the pressure teeth 45 with the elastic friction layer 46, and on the other side, the strip block 27 provides locking force through the engagement of the elastic friction layer 46 with the pressure teeth 45 on the pressure plate 18. At the same time, the two first helical springs 28 are compressed, and their elastic restoring force keeps the pressure block 26 and the strip block 27 tending to be tensioned to both sides, ensuring that the pressure teeth 45 on both sides and the elastic friction layer 46 always maintain a tight engagement. Through the cooperation of the pressure block 26, the first helical springs 28, the strip block 27 and the pressure plate 18, bidirectional clamping and locking of the slider 21 is achieved. Compared with unilateral locking, the bidirectional locking structure can effectively resist the impact and vibration from two opposite directions during hoisting, further improving the positional stability of the slider 21 under hoisting force.

[0035] Preferred, such as Figure 4 and Figure 5As shown, a connecting block 47 is fixedly provided at the lower end of the guide rod 43. One end of each of the two connecting rods 42 is rotatably connected to both sides of the connecting block 47, and the other end of the connecting rod 42 is rotatably connected to the lower end of the corresponding mating block 41. A second helical spring 48 is sleeved on the guide rod 43, and the second helical spring 48 is connected between the connecting block 47 and the bottom of the longitudinal beam 12. When the second helical spring 48 is in its natural state, the strip plate 44 and the two sliders 21 on the adjacent crossbeam 11 are spaced apart by a predetermined distance, that is, the strip plate 44 and the sliders 21 are kept separated. After the hoisting operation is completed and the power supply box 6 is in place, the operator releases the lifting action of the main hook on the guide rod 43. At this time, the second helical spring 48 is released. The elastic potential energy stored in the coil spring 48 is released, and its tension pushes the connecting block 47 downward. The guide rod 43 automatically descends relative to the longitudinal beam 12. The guide rod 43 drives the two connecting rods 42 to move through the connecting block 47, thereby pulling the two mating blocks 41 closer together. The strip plate 44 moves with the mating block 41 and quickly disengages from the slider 21 until it returns to its initial position at a predetermined distance from the slider 21. In this position, the operator does not need to manually adjust the position of the strip plate 44, but can directly operate the second locking component 5 to lock the mating block 41, complete the reset of the device, and put it in standby state, which improves the convenience and efficiency of hoisting operation.

[0036] Specifically, such as Figure 4 and Figure 6 As shown, the second locking assembly 5 includes two sets of portal frames 51 mounted on the top of the longitudinal beam 12 and two locking pins 52. The moving path of the mating block 41 is located inside the portal frames 51. The portal frames 51 span the top of the longitudinal beam 12, and their two side supports are fixed to the longitudinal beam 12, forming a channel for the mating block 41 to pass through. The top of the portal frames 51 has a downward-pointing locking hole 53, and the top of the mating block 41 has a mating hole 54. When the strip plate 44 is spaced a predetermined distance from the two sliders 21 on the adjacent crossbeam 11, the mating hole 54 and the corresponding locking hole 53 are aligned vertically. The locking pins 52 are used to insert into the locking hole 53 and the mating hole 54 to fix the mating block 41. Through the cooperation of the portal frames 51 and the locking pins 52, the mating block 41 is quickly and reliably locked at a predetermined position. The design of the automatic alignment of the locking hole 53 and the mating hole 54 at a predetermined distance allows the device to be locked without additional alignment operations after reset, simplifying the operation process and improving the efficiency of hoisting operations.

[0037] Example 2 As a further implementation of the above embodiment 1, such as Figure 1 , Figure 2 , Figure 4As shown, rotating seats 13 are provided on both sides of the middle part of the load-bearing beam 1. Here, "both sides" refers to the two sides of the two crossbeams 11 facing away from each other. Each rotating seat 13 is rotatably connected to the middle part of a swing rod 14. The rotation axis of the swing rod 14 is set parallel to the crossbeam 11. The upper end of the swing rod 14 is slidably fitted with a movable block 15 along its length direction. The lower end of the swing rod 14 is connected to a limiting rod 16 parallel to the crossbeam 11. The upper ends of the two mating blocks 41 are each connected to a push rod 17 arranged along the length direction of the longitudinal beam 12 and facing the adjacent swing rod 14. The end of the push rod 17 is rotatably connected to the corresponding movable block 15, and its rotation axis is set parallel to the crossbeam 11.

[0038] During the preparation stage, the two strip plates 44 are spaced at a predetermined distance from the two sliders 21 on the adjacent crossbeam 11, that is, the strip plates 44 and the sliders 21 are kept separated. In this state, the two mating blocks 41 are in a close position, and the push rod 17 is in a close position along with the mating blocks 41. The end of the push rod 17 pulls the upper ends of the two swing rods 14 together through the movable block 15, so that the two swing rods 14 rotate inward around the rotating seat 13, thereby driving the limiting rods 16 at the lower end of the two swing rods 14 to separate from each other. At this time, the distance between the two limiting rods 16 is greater than the width of the power supply box, leaving sufficient operating space for the entry of the power supply box and the hooking of the hook.

[0039] The subsequent trial lifting and leveling stages are consistent with the steps in Example 1. Before the formal lifting, the locking of the second locking component 5 on the mating block 41 is released. Due to the supporting effect of the second helical spring 48, the strip plate 44 remains separated from the slider 21.

[0040] like Figure 8 and Figure 9As shown, after entering the formal hoisting stage, the crane's main hook first pulls the lifting ring 49 at the upper end of the guide rod 43 upward. The guide rod 43 rises relative to the longitudinal beam 12, overcoming the elastic force of the second helical spring 48. The second helical spring 48 is compressed. The rise of the guide rod 43 pushes the two mating blocks 41 to separate from each other along the longitudinal beam 12 through the connecting rod 42. When the mating blocks 41 separate, two linkage effects are produced: First, the mating blocks 41 drive the strip plate 44 to move, and the strip plate 44 presses against one side of the two sliders 21 on the adjacent crossbeam 11, locking the sliders 21 in the leveled position; Second, the mating blocks 41 drive the push rod 17 to move. The push rod 17 moves outward as the mating blocks 41 separate. The end of the push rod 17 opens the upper ends of the two swing rods 14 through the movable block 15, causing the two swing rods 14 to move outward around the rotating seat 13. The lateral rotation causes the limiting rods 16 at the lower ends of the two swing rods 14 to close together. When the guide rod 43 rises to its position and the strip plate 44 is fully pressed against the slider 21, the two limiting rods 16 close simultaneously to abut against the two side walls of the power supply box. At this time, the slider 21 is locked by the strip plate 44, and the two sides of the power supply box are clamped and fixed by the limiting rods 16, forming a double constraint on the power supply box. The crane continues to lift, and the pulling force of the main hook is transmitted to the slider 21 through the guide rod 43, connecting rod 42, mating block 41, and strip plate 44. Then, the power supply box is moved upward as a whole through the sling and hook. During this process, the second helical spring 48 remains compressed, and the limiting rods 16 always abut against the two sides of the power supply box, effectively constraining the lateral swing and rotational freedom of the power supply box during the lifting process, ensuring the stability of the lifting posture.

[0041] The hoisting structure, through a linkage mechanism consisting of push rod 17, movable block 15, swing rod 14, and limiting rod 16, synchronously transforms the separation and approaching motion of mating block 41 into the closing and separation motion of limiting rod 16, realizing the linkage control of lifting point locking and lateral clamping. During the formal hoisting process, the main hook automatically locks the slider 21 and laterally clamps the power supply box while lifting the guide rod 43, requiring no additional operation, simplifying the hoisting process and improving work efficiency. At the same time, during the formal hoisting process, the limiting rod 16 always abuts against both sides of the power supply box, effectively constraining the lateral swing and rotational freedom of the power supply box during the hoisting process, avoiding box swaying caused by wind load, inertial force, or sling swing, and significantly improving the stability and safety of the hoisting process.

[0042] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
