Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a group hoisting installation system and hoisting method suitable for simultaneous hoisting of multiple components in an array. Background Technology

[0002] The assembly and maintenance of precision equipment often involves the installation and disassembly of a large number of columnar components arranged in an equidistant array. These components typically have the following characteristics: large number, regular distribution, need for precise positioning, and need to be disassembled and reassembled periodically according to usage requirements.

[0003] Traditional component installation methods involve hoisting each component individually. The process is as follows: First, the component is lifted out of its packaging box. Then, it is flipped from a horizontal position to a vertical position for hoisting. Finally, an overhead crane slowly lifts the individual component into the designated position in the array, where it is slowly positioned with manual assistance. This traditional method has the following significant drawbacks:

[0004] 1. Low work efficiency: It takes about 30 minutes to lift a single component out of the packaging box and into place in the equipment. For equipment containing dozens of components, it takes nearly a week to install all the components and also nearly a week to remove the components.

[0005] 2. Long equipment downtime: Due to the long installation and dismantling period, the effective operating time of the equipment is greatly reduced, which affects production efficiency and economic benefits.

[0006] 3. Frequent repetitive operations: Each component requires independent flipping, lifting, alignment, and placement operations, resulting in high workload and a high risk of operational errors.

[0007] 4. Difficulty in precision control: When hoisting a single piece, it is difficult to guarantee the relative positional accuracy between multiple components, which may require repeated adjustments.

[0008] 5. Waste of human resources: Long-duration hoisting operations require specialized operators and support staff, resulting in high labor costs.

[0009] Therefore, there is an urgent need for a new hoisting technology that can simultaneously hoist multiple components, significantly shorten the installation / dismantling period, and improve work efficiency and positioning accuracy. Utility Model Content

[0010] The purpose of this utility model is to provide an array group hoisting installation system to solve the technical problems of low efficiency, long construction period and difficulty in precision control of single-part hoisting in the prior art, so as to realize the synchronous hoisting of multiple parts, significantly improve assembly efficiency and ensure installation accuracy.

[0011] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0012] An array-based hoisting system includes hoisting tools and component storage racks.

[0013] The group lifting tool includes a main structure, a lifting plate, wire ropes, a hook connecting block, a hook, a pull rope, and a limit plate.

[0014] The main structure is a frame structure, with a level instrument on its upper surface for horizontal adjustment. The main structure serves as the load-bearing skeleton of the entire hoisting system, supporting the total weight of multiple components and ensuring horizontal alignment during the hoisting process through the level instrument.

[0015] The lifting platform is installed around the main structure and is fixedly connected to it. The platform has upper and lower lifting holes. The upper lifting hole is used to connect the lifting equipment, and the lower lifting hole is used to connect the pull rope to achieve force transmission.

[0016] One end of the wire rope is connected to the upper lifting hole of the lifting platform, and the other end is used to connect to the lifting equipment. As the main load-bearing component, the wire rope transmits the lifting force of the lifting equipment to the entire lifting assembly.

[0017] The hook connecting blocks are fixedly connected to the main structure, and the center positions and spacing of the multiple hook connecting blocks match the array spacing of the components to be lifted. This design ensures that the components maintain the correct relative positional relationship during lifting.

[0018] The hook is connected to the main structure via a hook connecting block. The hook can rotate within a certain angle around the connecting shaft, and the hook is equipped with an anti-detachment buckle. The rotatable design of the hook allows it to adapt to changes in the angle of the component's lifting lugs, while the anti-detachment buckle ensures safety during the lifting process.

[0019] The upper end of the pull rope is connected to the lower lifting hole of the lifting plate, and the lower end is connected to the limiting plate. The pull rope is made of flexible material, which can adapt to the position adjustment of the limiting plate during the lifting process.

[0020] The limiting plate is located at the lower end of the lifting tool. Multiple positioning holes are provided in the center of the limiting plate. The size and spacing of the positioning holes match the external dimensions and array spacing of the components to be lifted, thus limiting the relative positions of the multiple components during the lifting process. The limiting plate is a key component for achieving precise positioning of multiple components, guiding and limiting the components through the positioning holes.

[0021] The component storage rack includes an upper positioning plate, a lower positioning plate, a base plate, and a column.

[0022] The upper positioning plate is set on the top of the component temporary storage rack, and the upper positioning plate is provided with a first positioning hole group that matches the upper shape of the component to be hoisted.

[0023] The lower positioning plate is located in the lower part of the component temporary storage rack, and the lower positioning plate is provided with a second positioning hole group that matches the lower shape of the component to be hoisted.

[0024] The spacing between the first and second positioning hole groups matches the array spacing of the components to be hoisted. The function of the component storage rack is to prepare a set of components in advance before the hoisting operation, keeping them in a vertical position and with the required spacing, thereby achieving continuous and efficient hoisting operations.

[0025] Furthermore, the main structure is formed by welding square tubes and angle steel, and the upper and lower surfaces are precision machined. The level is a bubble level, set in two mutually perpendicular directions on the upper surface of the main structure. This design ensures the high strength and high precision of the main structure, and the bidirectional level can comprehensively monitor the horizontal status of the instrument.

[0026] Furthermore, there are four hanging platforms, each positioned around the perimeter of the main structure; the four pull ropes are made of flexible material and are of uniform length to ensure the limiting plates are level. This four-point suspension design ensures even load distribution and structural stability.

[0027] Furthermore, the number of hook connecting blocks is four, corresponding to four components to be lifted; the opening directions of adjacent hooks are arranged opposite each other in pairs. The opposite arrangement of the hook opening directions facilitates the loading and unloading of components and improves operational convenience.

[0028] Furthermore, the positioning holes of the limiting plate are square holes, and the limiting plate is provided with lifting lugs around its perimeter, which are connected to the pull rope; the number of positioning holes is four. The square hole design can effectively limit the position of rectangular or square cross-section components, preventing the components from rotating during hoisting.

[0029] Furthermore, the first positioning hole of the upper positioning plate is a square hole, and the second positioning hole of the lower positioning plate is a round hole; the number of columns is four, which are respectively set on the outer perimeter of the base plate. The design of using square holes at the top and round holes at the bottom ensures the stability of the component's posture and facilitates the installation and removal of the component.

[0030] This utility model also provides a hoisting method using the above-mentioned array group hoisting system, including the following steps:

[0031] Step 1: After installing the lifting lugs on the components to be hoisted, use an auxiliary crane to flip the components from a horizontal state to a vertical state, and hoist them into the component storage rack in sequence. The upper and lower positioning plates are used to keep multiple components in a vertical position and ensure that the spacing meets the array arrangement requirements.

[0032] Step 2: Connect the lifting equipment hook to the group lifting tool via a wire rope, and move the lifting equipment so that the group lifting tool is directly above the component storage rack.

[0033] Step 3: Lower the lifting tool, install the limit plate into the upper section of the component, and connect the hook to the lifting lug of the component.

[0034] Step 4: Lift the hoisting equipment to lift multiple components from the component storage rack at the same time, and move the hoisting equipment to move the components above the array installation position of the equipment.

[0035] Step 5: Lower the hoisting tool, guide multiple components with the limit plate to align them with the mounting holes simultaneously, and lower the components into place.

[0036] Step 6: Disconnect the hook from the component lifting lug, lift the group lifting tool, and complete the synchronous installation of multiple components.

[0037] Furthermore, in step 5, the limiting plate is manually controlled to slowly guide the chamfered lower part of the component into the mounting hole, while the limiting plate is manually lifted until the component is in place. This manual assistance allows for fine-tuning of the component's entry angle and speed, preventing collision damage.

[0038] Furthermore, during the hoisting process in steps 4 to 6, the next group of components to be hoisted is simultaneously placed into the component storage rack in numerical order in the preparation area, achieving continuous hoisting operations. This assembly line operation method maximizes the use of time and further improves overall efficiency.

[0039] Furthermore, the method is also applicable to the disassembly of components. The disassembly process is the reverse of the installation process, in which multiple components are simultaneously lifted out of the equipment and stored in a component storage rack using a multi-lifting tool.

[0040] The beneficial effects of this utility model are:

[0041] 1. Significantly improves work efficiency: Through simultaneous hoisting of multiple components, the installation of 4 or more components can be completed in a single operation. Compared with the traditional single-component hoisting method, it can save more than 60% of the installation / dismantling time, shortening the original construction period of nearly a week to 2-3 days.

[0042] 2. Ensure precise installation accuracy: The positioning holes of the limit plate and the positioning plate of the component storage rack mechanically ensure the relative positional accuracy between multiple components, avoiding the cumulative errors that may occur from manual positioning one by one.

[0043] 3. Increase effective equipment operating time: The significant reduction in installation / disassembly time directly increases the effective operating time of the equipment, thereby improving equipment utilization and production efficiency.

[0044] 4. Reduced labor intensity: Simultaneous hoisting of multiple components reduces the number of repetitive operations, lowers the labor intensity of operators, and reduces the risk of operational errors caused by long-term repetitive work.

[0045] 5. Enable assembly line operation: The component storage rack enables the pre-preparation of the next set of components, allowing hoisting operations to be carried out continuously and further improving overall operation efficiency.

[0046] 6. Simple and reliable structure: The temporary storage rack for hoisting tools and parts has a simple structure, is easy to process and manufacture, has low maintenance costs, and a long service life.

[0047] 7. High safety: The hook is equipped with an anti-detachment buckle, the pull rope is made of flexible material with a cushioning effect, and the limit plate provides guidance to prevent collision. Multiple safety measures ensure the safety of the hoisting process.

[0048] 8. High adaptability: The technical solution of this utility model can be expanded to the synchronous hoisting of 6, 8 or more components according to actual needs, and has good scalability and adaptability. Attached Figure Description

[0054] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0055] Example 1

[0056] As attached Figure 1 and attached Figure 2 As shown, this embodiment provides an array group hoisting installation system, including group hoisting tools and component storage racks.

[0057] Structure of a group lifting tool:

[0058] The main structure 1 is a frame structure, welded from 40mm×40mm square tubing and 50mm×50mm angle steel to form a frame 1200mm long, 1200mm wide, and 200mm high. The upper and lower surfaces of the main structure 1 are precision machined, with surface flatness controlled within 0.5mm. A bubble level is installed on each of the two perpendicular directions on the upper surface of the main structure 1 to monitor the horizontal status of the hoisting equipment in real time.

[0059] There are four hanging plates 2 in total, made of 10mm thick Q235 steel plate, with dimensions of 150mm × 100mm. The four hanging plates 2 are welded and fixed to the center positions of the four sides of the main structure 1. Each hanging plate 2 has an upper hanging hole with a diameter of 30mm and a lower hanging hole with a diameter of 20mm.

[0060] Wire rope 3 is a 6×19 wire rope with a diameter of 16mm and a length of 3000mm. One end of wire rope 3 is connected to the upper lifting hole of the lifting plate 2 through a shackle, and the other end forms a lifting ring for connecting to the crane hook of the factory. The upper ends of the four wire ropes 3 converge at one point and are connected to the crane hook through a main lifting ring.

[0061] There are four hook connecting blocks 4, made of 15mm thick Q235 steel plate, with dimensions of 100mm × 80mm. The four hook connecting blocks 4 are welded to the lower surface of the main structure 1 in a square arrangement, with a center-to-center spacing of 600mm, consistent with the array arrangement spacing of the components 13 to be hoisted. Each hook connecting block 4 has a 20mm diameter connecting hole in its center.

[0062] There are four hooks 5 in total, forged from No. 20 steel, with a rated load of 500 kg. Each hook 5 is connected to a hook connecting block 4 via an 18mm diameter connecting shaft, allowing rotation around the connecting shaft within a ±15° range. Each hook 5 has a spring-loaded anti-disengagement latch at the hook opening to prevent accidental disengagement during lifting. The openings of adjacent hooks 5 are arranged opposite each other, facilitating hooking and unhooking operations from different directions.

[0063] There are four pull ropes 6 in total, made of 12mm diameter nylon rope, with a length of 1500mm. The lengths of the four pull ropes 6 are precisely measured to ensure an error within ±5mm. The upper end of the pull rope 6 is connected to the lower lifting hole of the hanging plate 2 via a rope buckle, and the lower end is connected to the lifting lug of the limiting plate 7 via a rope buckle.

[0064] The limiting plate 7 is made of 8mm thick Q235 steel plate, with dimensions of 1000mm × 1000mm. Four square holes, each 120mm × 120mm in size, are arranged in a square pattern in the center of the limiting plate 7, with a center-to-center spacing of 600mm, matching the external dimensions and array spacing of the component 13 to be hoisted. The four corners of the square holes are rounded with R10 to prevent scratching the component 13. Four lifting lugs are provided around the perimeter of the limiting plate 7. These lugs are made of 16mm diameter round steel bent into rings and welded to the limiting plate 7.

[0065] Structure of the component storage rack:

[0066] like Figure 3 and Figure 4 As shown, the component storage rack includes an upper positioning plate 9, a lower positioning plate 10, a base plate 11, and a column 12.

[0067] The upper positioning plate 9 is made of 10mm thick Q235 steel plate, with dimensions of 800mm × 800mm. Four square holes, each 125mm × 125mm in size, are arranged in a square pattern in the center of the upper positioning plate 9, with a center-to-center spacing of 600mm. This arrangement matches the upper dimensions and array spacing of component 13. The square holes are slightly larger than the upper dimensions of component 13, facilitating insertion and removal of component 13, while ensuring that the dimensional accuracy of the holes prevents excessive wobbling of component 13.

[0068] The lower positioning plate 10 is made of 10mm thick Q235 steel plate, with dimensions of 800mm × 800mm. Four circular holes, each 115mm in diameter and 600mm apart, are arranged in a square pattern in the center of the lower positioning plate 10, matching the dimensions and array spacing of the lower part of component 13. The circular holes are used because the lower part of component 13 has a circular cross-section, and the holes provide better support and positioning.

[0069] The base plate 11 is made of Q235 steel plate with a thickness of 12mm and a size of 1000mm×1000mm, providing sufficient load-bearing area and structural strength.

[0070] There are four uprights 12, made of seamless steel pipe with a diameter of 60mm and a length of 2500mm. The four uprights 12 are welded to the four corners of the base plate 11, located on the outer perimeter of the base plate 11. The upper positioning plate 9 is welded and fixed to the top of the four uprights 12, and the lower positioning plate 10 is welded and fixed at a height of about 500mm from the base plate 11.

[0071] Lifting method:

[0072] In this embodiment, the above-mentioned array group hoisting system is used to hoist the four components 13 simultaneously. The specific steps are as follows:

[0073] Step 1: Place the component storage rack in the installation preparation area, ensuring that the base plate 11 is placed stably. Install the lifting lugs 14 on the component 13 to be hoisted, and fix the lifting lugs 14 in the pre-drilled threaded holes of the component 13 with M16 bolts.

[0074] Step 2: Use a small, movable gantry crane to lift component 13 out of the packaging box. Component 13 is horizontal inside the packaging box; use the gantry crane's rotation function to flip component 13 from a horizontal position to a vertical position.

[0075] Step 3: Using a gantry crane, slowly lift the vertically positioned component 13 and move it above the component storage rack. First, pass the lower part of component 13 through the square hole in the upper positioning plate 9, and continue lowering it until the lower part of component 13 enters the round hole in the lower positioning plate 10. The lower part of component 13 has a chamfer to facilitate insertion into the round hole. Stop lowering when the lower end of component 13 is about 50mm away from the base plate 11, so that component 13 is suspended vertically and stored in the storage rack.

[0076] Step 4: Following the installation sequence number of components 13, place the remaining 3 components 13 in the temporary storage rack in order. Through the positioning action of the upper positioning plate 9 and the lower positioning plate 10, the 4 components 13 maintain a vertical posture, and the center distance between them is precisely maintained at 600mm.

[0077] Step 5: Connect the crane hooks in the factory to the group lifting tools via the main lifting ring and wire rope 3. Operate the crane to move the group lifting tools directly above the component storage rack. By visually observing and fine-tuning the crane position, align the four hooks 5 of the group lifting tools with the lifting lugs 14 of the four components 13 respectively.

[0078] Step 6: Slowly lower the overhead crane hooks, and the group lifting tools will follow. First, lower the limiting plate 7 above the four components 13. Continue lowering until the four square holes of the limiting plate 7 fit onto the upper outer sides of the four components 13. At this point, the limiting plate 7 provides initial restraint for the four components 13. Continue to lower slowly until the four hooks 5 approach the corresponding lifting lugs 14 of the components 13. The operator assists in adjusting the angle of the hooks 5, hooking the hooks 5 into the lifting lugs 14, and confirms that the anti-derailment buckles are engaged. Check whether the connection between the four hooks 5 and the lifting lugs 14 is secure and reliable.

[0079] Step 7: Slowly raise the overhead crane hook, and the group lifting tools begin to bear force. Through the force transmission path of wire rope 3, lifting plate 2, main structure 1, hook connecting block 4, and hook 5, the lifting force of the overhead crane is transmitted to the four components 13. Simultaneously, the tension rope 6 lifts the limiting plate 7. Continuing to lift, the lower ends of the four components 13 gradually disengage from the round holes of the lower positioning plate 10, and then the upper parts of the four components 13 disengage from the square holes of the upper positioning plate 9. The four components 13 are then completely vertically lifted out of the component storage rack. During the lifting process, observe the level on the main structure 1 and make minor adjustments to the overhead crane position to ensure the group lifting tools remain horizontal.

[0080] Step 8: Operate the overhead crane and slowly move the group lifting tool. The four components 13 maintain their relative positions under the limiting action of the limiting plate 7, moving as a whole with the group lifting tool. Move the four components 13 above the array installation position within the equipment, ensuring their center positions are roughly aligned with the equipment's mounting holes.

[0081] Step 9: After the overhead crane and the hoisting tools have stabilized, observe the level on the main structure 1 to confirm that the hoisting tools are horizontal. Slowly lower the hoisting tools while the operator observes and guides them. When the four components 13 are lowered to approximately 500mm from the equipment mounting holes, visually assess the alignment of components 13 with the mounting holes. Based on the observation, fine-tune the front-back, left-right, and right positions of the overhead crane to ensure that the positions of the four components 13 precisely correspond to the positions of the four mounting holes.

[0082] Step 10: Continue to slowly lower the hoisting tool, maintaining the correct relative position of the four components 13 under the guidance of the four square holes in the limiting plate 7, while descending simultaneously. The size of the square holes in the limiting plate 7 is appropriately matched to the upper outer dimensions of the components 13, which can both restrict the horizontal position of the components 13 and avoid generating excessive frictional resistance. When the lower ends of the four components 13 approach the equipment mounting holes, the operator begins to assist in controlling the limiting plate 7.

[0083] Step 11: The lower part of component 13 has a chamfer. The operator holds the edge of the limiting plate 7 and slightly adjusts its horizontal position and orientation so that the lower chamfers of the four components 13 are aligned with the mounting holes. Continue to lower slowly, as the chamfers at the bottom of component 13 act as guides, leading the lower end of component 13 into the mounting holes. During the descent of component 13, the operator simultaneously and slowly raises the limiting plate 7, allowing it to slide upwards along component 13 to prevent collision between the limiting plate 7 and the upper surface of the equipment.

[0084] Step 12: Continue lowering the hoisting tool, with the four components 13 descending synchronously and gradually entering the mounting holes. The operator continues to raise the limit plate 7. When the limit plate 7 is raised to the point where it is detached from the upper end of the component 13, the four components 13 have descended to a state close to being installed in place. Continue lowering until the positioning steps of the four components 13 contact the positioning surface of the equipment mounting hole. At this point, the four components 13 are fully installed in place.

[0085] Step 13: The operator opens the anti-detachment buckle of hook 5 and detaches hook 5 from the lifting lug 14 of component 13. After all four hooks 5 are detached, the overhead crane hooks are slowly raised, and the lifting tools rise and detach from component 13. The operator then removes the lifting lug 14 from component 13.

[0086] Step 14: Operate the overhead crane to move the group lifting tools back to directly above the component storage rack, preparing for the lifting of the next group of components. During the lifting process from Steps 8 to 13, another group of operators has already placed the next group of 4 components 13 onto the component storage rack in the installation preparation area according to their numbering order, realizing a continuous assembly line operation.

[0087] Step 15: Repeat steps 6 to 14 to complete the hoisting of all component groups in sequence until all components inside the equipment are installed.

[0088] Using the array-group hoisting installation system and method of this embodiment, the time from taking four components out of the temporary storage rack to installing them in place is approximately 25 minutes, which is about 80% more efficient than the traditional single-component hoisting method, which takes 30 minutes per component. For equipment containing 48 components, the traditional method requires about 24 hours of work time, while the method of this invention only requires about 5 hours. Including preparation and conversion time, the total construction period can be shortened from 7 days to less than 2 days, significantly improving work efficiency.

[0089] Component disassembly:

[0090] The array group hoisting system of this utility model is also applicable to the disassembly of component 13. The disassembly process is the reverse of the installation process, as detailed below:

[0091] Install lifting lugs 14 on component 13; operate the overhead crane to lower the lifting tool above component 13; fit the limiting plate 7 onto the upper section of component 13, and connect the hook 5 to the lifting lugs 14; lift the lifting tool, and simultaneously lift all four components 13 out of the equipment mounting holes; move the overhead crane to transfer the four components 13 above the component storage rack; lower the lifting tool and place the four components 13 into the component storage rack; detach the hook 5 and remove the lifting lugs 14.

[0092] Using multi-pronged lifting tools, multiple components can be disassembled simultaneously, which also significantly shortens the disassembly period.

[0093] Example 2

[0094] The difference between this embodiment and Embodiment 1 lies in the dimensions of the group lifting tools and component storage rack, as well as the number of components to be lifted simultaneously.

[0095] This embodiment is designed as a group lifting system for 6 components. The main structure 1 is enlarged to a length of 1500mm and a width of 900mm. There are 6 hook connecting blocks 4, arranged in a 2x3 rectangular array with a row spacing of 600mm and a column spacing of 400mm, consistent with the array arrangement of the components to be lifted. Correspondingly, the limiting plate 7 has 6 positioning holes arranged in a 2x3 pattern. The upper positioning plate 9 and lower positioning plate 10 of the component storage rack also have 6 positioning holes arranged in a 2x3 pattern.

[0096] The 6-component group hoisting system of this embodiment allows for the simultaneous hoisting of 6 components in a single operation, further improving work efficiency. For equipment containing 48 components, only 8 hoisting operations are required to complete the entire installation, further shortening the total construction period.

[0097] Example 3

[0098] The difference between this embodiment and Embodiment 1 lies in the shape design of the positioning hole of the limiting plate.

[0099] In this embodiment, for components with a circular cross-section, the positioning hole of the limiting plate 7 is designed as a circular hole, with a diameter equal to the outer diameter of the component plus a gap of 5-10 mm. The circular hole provides better positioning for the circular cross-section component and facilitates the component's up-and-down sliding within the limiting plate.

[0100] The first positioning hole of the upper positioning plate 9 of the component temporary storage rack is also a round hole design, with the diameter of the round hole slightly larger than the outer diameter of the upper part of the component; the second positioning hole of the lower positioning plate 10 is also a round hole, with the diameter slightly larger than the outer diameter of the lower part of the component.

[0101] This embodiment is applicable to the group hoisting installation of cylindrical components with circular cross-sections, and can also achieve synchronous and precise hoisting of multiple components.

[0102] Example 4

[0103] This embodiment provides an improved design for a group hoisting tool, which adds an automatic leveling function.

[0104] Hydraulic leveling devices are installed at the four corners of the main structure 1. Each hydraulic leveling device includes a hydraulic cylinder and an angle sensor. The angle sensor monitors the tilt angle of the main structure 1 in real time, and the control system drives the hydraulic cylinder to extend and retract, automatically adjusting the posture of the main structure 1 to keep it level.

[0105] This automatic leveling design reduces the need for operators to frequently fine-tune the position of the overhead crane, improving the automation level and efficiency of hoisting operations, and is particularly suitable for group hoisting operations of large, heavy-duty components.

[0106] Example 5

[0107] This embodiment provides a group lifting system for precision components, which adds a buffer and shock absorption device.

[0108] A spring buffer is installed between the hook 5 and the hook connecting block 4. The spring buffer consists of a disc spring assembly and a guide sleeve. When the lifting tool is lifted or lowered, the spring buffer can absorb the impact load, reduce the impact on the components, and protect the precision components from damage.

[0109] A rubber buffer strip is attached to the inner wall of the positioning hole of the limiting plate 7. When the part comes into contact with the positioning hole wall, the rubber buffer strip plays a buffering and protective role, preventing the surface of the part from being scratched.

[0110] This embodiment is particularly suitable for the group hoisting installation of precision components that require high surface quality and are easily damaged.

[0111] Industrial application

[0112] The array group hoisting system and method of this utility model have broad industrial application prospects, and are particularly suitable for the following fields:

[0113] 1. Precision equipment manufacturing: In the assembly process of precision machining equipment, testing equipment, scientific instruments, etc., a large number of precision components are often involved in the array installation. This utility model can significantly improve assembly efficiency and accuracy.

[0114] 2. Nuclear power plant maintenance: The fuel rods, control rods and other components of a nuclear reactor are arranged in an array and need to be replaced periodically.
