Description

Technical Field

[0001] This invention belongs to the field of lifting equipment technology, and particularly relates to a beam-type lifting mechanism. Background Technology

[0002] In the final assembly process of aerospace products, hoisting operations are an indispensable key process for realizing the transfer, attitude adjustment, and assembly docking of components. Current hoisting operations generally adopt the operation mode of using an overhead crane with a lifting device: first, the overhead crane hook is connected to the main body of the lifting device, and then the lifting points on the lifting device are connected to the object being hoisted through slings, thereby completing operations such as lifting, transfer, and alignment.

[0003] In aerospace assembly scenarios, the objects being lifted encompass various specifications and different center-of-gravity distributions of components and complete machines. When lifting different objects, the lifting points of the lifting equipment need to be frequently changed or adjusted according to the product size, center of gravity position, and lifting posture requirements. However, existing conventional lifting equipment mostly has fixed lifting points or only supports manually adjustable movable lifting points. Each time the lifting points are adjusted, the overhead crane must lower the entire lifting equipment to a low height where personnel can operate safely. The operator then manually performs operations such as lifting point relocation, sling replacement, and tightening. After the lifting points are adjusted, the overhead crane is controlled to raise the lifting equipment back to the working height before the lifting process can continue. However, existing solutions have drawbacks such as low work efficiency, high labor intensity, and poor ease of operation. For example, the lifting point adjustment process must be accompanied by the full lifting and lowering of the lifting equipment. The crane has a long lifting stroke, auxiliary operations are time-consuming, and the lifting and adjustment process must be repeated every time the object being lifted is changed, which seriously slows down the final assembly lifting pace and is difficult to adapt to the needs of multi-variety, small-batch aerospace final assembly operations. The lifting point replacement relies entirely on manual operation, and the final assembly position itself is a physically demanding job. Frequent low-position replacement, bolt tightening, and alignment operations further increase the workload of operators. Long-term operation can easily lead to fatigue, and the operation process is cumbersome and the lifting equipment is not easy to use. Therefore, it is necessary to design a beam-type hoisting mechanism to reduce manual operation and shorten the auxiliary time for hoisting point adjustment. This is of great practical significance for improving the hoisting efficiency of aerospace assembly and reducing operational intensity. Summary of the Invention

[0004] To address the technical issues mentioned in the background art regarding the need to reduce manual operation steps and shorten the auxiliary time for adjusting lifting points, a beam-type lifting mechanism is provided.

[0005] To achieve the above objectives, the specific technical solution of the beam-type hoisting mechanism of the present invention is as follows: A beam-type hoisting mechanism, comprising: The main beam is equipped with a sliding groove that extends along the length of the main beam. Two lifting components, both of which are slidably installed within the sliding groove; Two drive components are respectively set at both ends along the length of the main beam. The two drive components are set one-to-one with the two hoisting components. The output end of each drive component is connected to the corresponding hoisting component. Along the extension direction of the slide, any drive component can drive the hoisting component connected to it to move closer to or away from the other hoisting component.

[0006] Furthermore, the main beam includes: The main beam body has a sliding groove installed on it. The lifting ring module consists of multiple modules, which are spaced apart on the main beam body.

[0007] Furthermore, the main beam also includes a leg module, which includes multiple support legs connected to the main beam body for supporting the main beam body. The leg module and the lifting ring module are located on opposite sides of the main beam body along its length.

[0008] Furthermore, the chute is configured as a through groove, and the hoisting assembly includes a lifting lug body and a transmission unit. The lifting lug body includes a mounting plate and lifting lug components. The mounting plate is configured as a U-shape, and the lifting lug components are located at the bottom of the mounting plate. The vertical line of the center of gravity of the lifting lug intersects with the central axis of the main beam body. The transmission unit passes through the mounting plate, and the middle position of the transmission unit is connected to the chute for transmission. Both ends of the transmission unit are connected to the drive assembly.

[0009] Furthermore, the transmission unit includes a transmission shaft and a transmission component. The transmission shaft passes through the mounting plate, and the transmission component is installed at the middle position of the transmission shaft and is connected to the slide groove for transmission. Both ends of the transmission shaft extend out of the mounting plate, and the extended parts of the transmission shaft are connected to the drive assembly.

[0010] Furthermore, the transmission unit also includes stop members disposed at both ends of the transmission shaft, which are used to prevent the output end of the drive assembly from disengaging from the transmission shaft.

[0011] Furthermore, the drive assembly includes two drive members spaced apart along the width of the main beam body. The two drive members are respectively connected to both ends of the drive shaft, and are used to simultaneously drive the hoisting assembly connected to them to move closer to or away from the other hoisting assembly.

[0012] Furthermore, the drive assembly also includes a mounting base, which includes a first mounting plate connected to the main beam body, a second mounting plate connected to the drive component, and connecting plates connected to the first and second mounting plates respectively. The mounting base also includes a support plate connected to the second mounting plate. The support plate and the second mounting plate are arranged perpendicular to each other and the support plate is located at the bottom of the drive component. The support plate is used to support the drive component.

[0013] Furthermore, the mounting base also includes a positioning piece, which is connected to the first mounting piece. The positioning piece and the first mounting piece are set perpendicular to each other. When the first mounting piece is connected to the main beam body, the positioning piece overlaps the upper side of the main beam body.

[0014] Furthermore, the chute is configured as a blind chute, and the hoisting assembly includes a transmission unit, a mounting plate, and lifting lugs. The lifting lugs are located at the bottom of the mounting plate, the transmission unit passes through the mounting plate and can slide within the chute, and the vertical line of the center of gravity of the lifting lugs intersects with the central axis of the main beam body. The output end of the drive assembly passes through the main beam body and extends into the chute, and the output end of the drive assembly is connected to the transmission unit located within the chute.

[0015] The beam-type hoisting mechanism of the present invention has the following advantages: By setting a sliding groove extending along the length of the main beam, the hoisting components are slidably positioned within the groove. The groove provides full-length linear guidance and limiting constraint for the hoisting components. During the sliding process, the hoisting points do not shift or laterally sway. When hoisting thin-walled aerospace modules or complete units, the product will not experience localized collisions or stress deformation due to the swinging of the hoisting points, significantly improving the protection capability of the hoisted finished product. Furthermore, drive components are correspondingly set at both ends of the main beam, independently driving two sets of hoisting components on each side. This allows for the separate control of the two sets of hoisting points to move closer or further apart, enabling infinitely precise adjustment of the hoisting point spacing according to the actual length and center of gravity distribution of the hoisted product. It is suitable for hoisting aerospace modules of various specifications and with multiple centers of gravity, significantly improving the versatility of the tooling. It is adaptable to hoisting aerospace modules and complete units of different lengths and center of gravity shifts, demonstrating strong versatility. Attached Figure Description

[0026] The following is a reference to the appendix. Figure 1 To be continued Figure 5 This invention describes a beam-type hoisting mechanism.

[0027] This embodiment provides a beam-type hoisting mechanism, such as Figure 1 and Figure 2As shown, the beam-type hoisting mechanism includes a main beam 1, two hoisting components 2, and two drive components 3. The main beam 1 is provided with a sliding groove 11. Both hoisting components 2 are slidably installed in the sliding groove 11, which extends along the length of the main beam. The two drive components 3 are respectively located at both ends along the length of the main beam 1. The two drive components 3 are arranged one-to-one with the two hoisting components 2. The output ends of the two drive components 3 are connected to the corresponding hoisting components 2. Along the extension direction of the sliding groove 11, any drive component 3 can drive the hoisting component 2 connected to it to move closer to or away from the other hoisting component 2.

[0028] Understandably, this beam-type hoisting mechanism uses a sliding groove 11 extending along the length of the main beam 1. The hoisting component 2 slides within the sliding groove 11, which provides full-length linear guidance and limiting constraint for the hoisting component 2. During the sliding process, the hoisting points do not shift or lateral sway. When hoisting thin-walled aerospace modules or complete machines, the product will not be subject to localized collisions or stress deformation due to the swinging of the hoisting points, significantly improving the protection capability of the hoisted finished product. In addition, drive components 3 are set at both ends of the main beam 1, independently driving two sets of hoisting components 2 on both sides. The two sets of hoisting points can be controlled to move closer or further apart, and the spacing between the hoisting points can be infinitely and precisely adjusted according to the actual length and center of gravity distribution of the hoisted product. It is suitable for hoisting aerospace modules of various specifications and with multiple centers of gravity, significantly improving the versatility of the tooling. It is suitable for hoisting aerospace modules and complete machines of different lengths and with different center of gravity shifts, demonstrating strong versatility.

[0029] It should be noted that the use of the slide 11 as the lifting component 2 provides linear guidance and limit, the lifting point will not shift or shake during the sliding process, the position of the lifting point is stable during the lifting process, and avoids uneven force on the product and damage from collisions caused by alignment deviations due to manual adjustment of the lifting point.

[0030] Furthermore, such as Figure 2 As shown, the main beam 1 includes a main beam body 12, a lifting ring module 13, and a support leg module 14. The sliding groove 11 is provided on the main beam body 12. Multiple lifting ring modules 13 are provided, and the multiple lifting ring modules 13 are spaced apart on the main beam body 12.

[0031] Understandably, the multiple sets of spaced lifting ring modules 13 can be matched with crane hooks of different tonnages and different lifting connection points in the workshop. A single main beam 1 can be adapted to a variety of lifting tools without replacing the entire set of crossbeams, thus reducing the cost of purchasing and storing lifting equipment. The support leg module 14 and the lifting ring are placed on both sides of the main beam 1. When not in use, the support leg 141 rests on the ground to bear the weight of the main beam 1, avoiding direct crushing and wear of the main beam 1 on the ground, thus extending the service life of the lifting equipment.

[0032] Furthermore, the outrigger module 14 includes multiple support legs 141 connected to the main beam body 12 for supporting the main beam body 12. The outrigger module 14 and the lifting ring module 13 are located on opposite sides of the main beam body 12 along its length. Due to the setting of the support legs 141, no additional storage brackets are required when storing the lifting equipment, saving workshop tooling storage space; the support legs 141 provide multi-point support for the main beam 1, making it less prone to bending deformation during transportation and storage, ensuring the straightness of the slide 11, and preventing deformation of the slide 11 from causing the lifting components 2 to jam or slide. The lifting rings and outriggers are arranged in layers and on both sides, so the lifting force area and the ground support area do not interfere with each other. During lifting, the support legs 141 will not interfere with the overhead crane or the product being lifted, resulting in better compatibility of the lifting operation space.

[0033] Furthermore, such as Figure 1 and Figure 2 As shown, the lifting ring module 13 includes a lifting ring body 131 and a lifting ring mounting plate 132. The lifting ring mounting plate 132 is disposed on the main beam body 11, and the lifting ring body 131 is mounted on the main beam body 11 through the lifting ring mounting plate 132.

[0034] Understandably, the use of a split lifting ring structure allows for individual disassembly and replacement of the lifting ring body 131 when it suffers wear, deformation, or other malfunctions, without the need for overall cutting and replacement of the main beam body 11. This approach offers advantages such as convenient maintenance and low maintenance costs.

[0035] In addition, by using the lifting ring mounting plate 132 to increase the contact area between the lifting ring body 131 and the main beam body 12, the concentrated lifting load is distributed, stress concentration and cracking at the lifting point of the main beam body 11 are avoided, and the structural safety of the hoisting of large-tonnage aerospace products is improved. The standardized mounting plate can be uniformly processed, and the same mounting plate can be used for different specifications of lifting ring bodies 131. The parts have strong interchangeability, which is convenient for mass production and spare parts storage.

[0036] In terms of connection, the lifting ring mounting plate 132 can be connected by welding or bolts, which can be adapted to different main beam body 11 materials. During disassembly and maintenance, there is no need to damage the main structure of the main beam body 11.

[0037] Furthermore, such as Figure 2 and Figure 3 As shown, the chute 11 is configured as a through groove, and the hoisting assembly 2 includes a lifting lug body 21 and a transmission unit 22. The lifting lug body 21 includes a mounting plate 211 and a lifting lug 212. The mounting plate 211 is U-shaped, and the lifting lug 212 is located at the bottom of the mounting plate 211. The vertical line of the center of gravity of the lifting lug 212 intersects with the central axis of the main beam body 12. The transmission unit 22 passes through the mounting plate 211, and the middle position of the transmission unit 22 is connected to the chute 11 for transmission. The two ends of the transmission unit 22 are connected to the drive assembly 3.

[0038] It is understandable that by passing the transmission unit 22 through the lifting lug body 21, the drive end synchronously drives the entire lifting lug to move along the slide 11. The transmission force is uniform, and there is no unilateral force tilting during the movement of the lifting lug, ensuring that the lifting lug is always horizontal and the lifted product is subjected to balanced force, preventing local pressure deformation of the thin-walled section of the aerospace. The middle part of the transmission unit 22 is connected to the slide 11, so that the slide 11 forms a radial limit on the transmission unit 22. During the movement, the lifting lug will not derail or deviate, and the sliding stability under high load lifting is greatly improved.

[0039] It should be noted that by connecting the two ends of the transmission unit 22 to the drive components 3 at both ends of the main beam 1 respectively, synchronous driving force on both sides is achieved. Compared with single-sided drive, the lifting lug will not experience single-sided dragging and jamming under the working condition of the long main beam 1, which is suitable for the hoisting of long aerospace complete machines. The lifting lug body 21 independently bears the load of the sling and the workpiece, and the transmission unit 22 is only responsible for displacement drive. The load and drive functions are separated, avoiding the transmission structure from bearing the heavy load and reducing the risk of wear and breakage of the transmission components.

[0040] Furthermore, such as Figure 2 and Figure 3 As shown, the transmission unit 22 includes a transmission shaft 221 and a transmission component 222. The transmission shaft 221 passes through the mounting plate 211, and the transmission component 222 is installed at the middle position of the transmission shaft 221 and is connected to the slide groove 11 for transmission. Both ends of the transmission shaft 221 extend out of the mounting plate 211, and the extended part of the transmission shaft 221 is connected to the drive assembly 3.

[0041] In implementation, the drive shaft 221 serves as a rigid force transmission base, with its extended ends directly connecting to the drive output shaft. This ensures seamless power transmission, rapid response during drive start-up and shutdown, and precise adjustment of the lifting point spacing. It can be precisely adjusted to the lifting point position, meeting the high-precision assembly and alignment requirements of aerospace products. The independent transmission component 222 in the middle meshes with the slide groove 11. The drive shaft 221 only transmits torque and does not directly rub against the slide groove 11. The drive shaft 221 is not prone to wear, and only the low-cost transmission component 222 needs to be replaced periodically, resulting in lower maintenance costs.

[0042] Understandably, the drive shaft 221 runs through the lifting lug body 21 to form an integral rigid structure. The lifting lug will not twist when moving or lifting loads, and the sling attachment point will always remain vertical, preventing the product from tipping over or shifting during hoisting. The drive shaft 221 has a uniform connection structure exposed at both ends, and the left and right drive components 3 are interchangeable. The parts are highly standardized, making assembly and spare parts replacement simpler.

[0043] Furthermore, such as Figure 2 and Figure 3 As shown, the transmission unit 22 also includes stop members 223 disposed at both ends of the transmission shaft 221. The stop members 223 are used to prevent the output end of the drive assembly 3 from disengaging from the transmission shaft 221.

[0044] In practical applications, due to impact loads and rapid start and stop of the lifting point during the lifting process, the stop 223 limits the drive output end, preventing the drive shaft and transmission shaft 221 from disengaging and failing, avoiding loss of power and uncontrolled sliding of the lifting lug, and preventing sudden attitude changes and collisions of the lifted aerospace products with the tooling. When disassembling and repairing the drive assembly 3, the stop 223 can be quickly disassembled without affecting the separation and repair of the drive and transmission shaft 221, taking into account both safety protection and maintenance convenience. Under the high-frequency lifting vibration environment, it prevents axial movement of the drive output end from wearing the mating surface, and extends the service life of the drive and transmission shaft 221 mating components.

[0045] In addition, under long-term reciprocating sliding and vibration conditions, the drive connection gap is prone to expansion. The stop 223 continuously constrains the axial displacement, reduces the probability of the drive connection loosening, reduces the number of equipment downtimes, and ensures continuous operation of the final assembly line.

[0046] Furthermore, such as Figure 1 , Figure 4 and Figure 5 As shown, the drive assembly 3 includes two drive members 31 spaced apart along the width direction of the main beam body 12. The two drive members 31 are respectively connected to both ends of the transmission shaft 221, and are used to simultaneously drive the hoisting assembly 2 connected to it to move closer to or away from the other hoisting assembly 2.

[0047] Understandably, the simultaneous power output from the left and right dual drive components 31 prevents one-sided dragging and jamming of the lifting lugs, making it suitable for hoisting long aerospace vehicles.

[0048] It should be noted that by adopting dual-drive synchronous output torque, the forces on both ends of the transmission shaft 221 are balanced, and there is no torsional stress on one side. The force loss of the transmission shaft 221, slide 11, and transmission component 222 is halved. If one drive component 31 fails, the other can temporarily maintain low-speed fine adjustment, avoiding direct interruption of the hoisting process, improving the fault tolerance of the equipment operation, and further extending the service life of the entire transmission mechanism.

[0049] Furthermore, such as Figure 1 and Figure 5 As shown, the drive assembly 3 also includes a mounting base 32, which includes a first mounting piece 321 connected to the main beam 1 body, a second mounting piece 322 connected to the drive member 31, and a connecting piece 323 connected to the first mounting piece 321 and the second mounting piece 322 respectively.

[0050] Understandably, by using the first mounting plate 321 to fit a large area against the end face of the main beam 1, the vibration of the drive operation is evenly distributed to the entire main beam 1, avoiding local stress concentration and cracking at the end of the main beam 1, and improving the structural strength of the end of the main beam 1. Secondly, the first mounting plate 321, the second mounting plate 322 and the connecting plate 323 form a frame support structure, which improves the rigidity of the mounting base 32 itself. Under long-term vibration, it is not easy to deform or misalign the mounting holes, ensuring that the drive output shaft and the transmission shaft 221 continue to coaxially transmit, with stable transmission efficiency and lower noise.

[0051] Specifically, the mounting base 32 also includes a support plate 324, which is connected to the second mounting plate 322. The support plate 324 and the second mounting plate 322 are arranged perpendicular to each other, and the support plate 324 is located at the bottom of the driving member 31. The support plate 324 is used to support the driving member 31.

[0052] Understandably, the bottom support plate 324 supports the bottom surface of the drive component 31, and fully bears the weight of the drive component 31 and the impact load of operation in the vertical direction, so as to avoid the drive component 31 being suspended by the side bolts alone, and prevent the bolts from fatigued and loosened, and the drive component from falling off.

[0053] Furthermore, the mounting base 32 also includes a positioning piece, which is connected to the first mounting piece 321. The positioning piece and the first mounting piece 321 are arranged perpendicular to each other. When the first mounting piece 321 is connected to the main beam 1 body, the positioning piece overlaps on the upper side of the main beam 1 body.

[0054] Understandably, when assembling the mounting base 32, the positioning piece directly overlaps the upper surface of the main beam 1 to form a quick positioning reference, eliminating the need for repeated manual measurement and calibration of the installation height and level, thus significantly shortening the tooling assembly time. If vibration or other situations occur during hoisting, the positioning piece, due to its contact with the top surface of the main beam 1, forms a bidirectional upper and lower limit, which will restrict the upward warping and displacement of the mounting base 32, thereby further improving the installation firmness of the drive component 31.

[0055] Optionally, since the blind groove structure provides a stronger overall enclosure for the main beam 1 compared to the through groove, dust and metal debris during the hoisting process are less likely to enter the groove, thereby reducing problems such as jamming and wear of the slide 11 and transmission components 222, and thus reducing the frequency of cleaning and maintenance, the slide 11 is set as a blind groove. The hoisting assembly includes a transmission unit, a mounting plate, and lifting lugs. The lifting lugs are located at the bottom of the mounting plate, the transmission unit passes through the mounting plate and can slide in the slide, and the vertical line of the center of gravity of the lifting lugs intersects with the central axis of the main beam body. The output end of the drive assembly passes through the main beam body and extends into the slide, and the output end of the drive assembly is connected to the transmission unit located in the slide.

[0056] Understandably, the blind slot provides lateral protection for the internal transmission unit, preventing pipelines and tooling from rubbing against the drive shaft and transmission components during lifting, thus avoiding damage to the transmission structure. The enclosed main beam structure exhibits superior bending and torsional resistance compared to a through-slot main beam, making it suitable for lifting larger tonnage aerospace products and further expanding the operational range of the beam-type lifting mechanism. Furthermore, by uniformly arranging the drive components on the open end face of the blind slot, with the power output directly connecting to the exposed section of the lifting components, the power transmission path is shorter, transmission losses are lower, and drive response is faster.

[0057] This embodiment also provides a hoisting device, including the above-mentioned beam hoisting mechanism, and further including a pressure sensor and an inclination sensor. The pressure sensor is disposed in the two hoisting components 2 and is used to detect the hoisting weight. The inclination sensor is disposed in the two drive components 3 and is used to detect the inclination of the main beam 1.

[0058] Understandably, the lifting equipment utilizes the built-in pressure sensors of the dual lifting components 2 to collect the loads of the lifting points on both sides in real time, quickly determine whether the center of gravity of the lifted aerospace product has shifted, and synchronously feed back to the drive components 3 to automatically fine-tune the distance between the lifting points, achieving fully automatic attitude correction without the need for manual visual observation or leveling; the sensor detection, combined with the automatic distance adjustment beam, realizes the integrated fully automatic operation of lifting point adjustment, load monitoring, and attitude correction, without the need for manual assistance in measurement and leveling throughout the process, further improving the automation level and operational efficiency of aerospace assembly lifting.

[0059] To more clearly illustrate the synergistic effect between the aforementioned beam-type hoisting mechanism and the two sensors (pressure sensor and tilt sensor), the following are the operational steps during the slow-speed hoisting process of the overhead crane. During hoisting, both manual and automatic hoisting point adjustment modes can be used. The manual adjustment mode is suitable for non-standard aerospace sections with special shapes and irregular center of gravity distribution. Operators can flexibly control the movement of the hoisting points according to the actual working conditions on site. It can quickly switch to automatic mode in case of abnormal sensor signals or automatic mode failure, providing emergency intervention capabilities and ensuring the continuous operation of the hoisting process. For standardized, mass-produced aerospace module products, the automatic adjustment mode can be used.

[0060] For manual suspension point adjustment mode: First, before the hoisting operation, the tooling and workpiece are attached. The operator switches the remote control to manual adjustment mode, starts the overhead crane to drive the beam hoisting mechanism to rise slowly, and the slings gradually carry the hoisted object and enter the attitude adjustment process. Afterwards, when the workpiece is subjected to force, the tilt sensor built into the drive component 3 continuously collects the tilt data of the main beam 1 and feeds it back to the equipment controller in real time. Afterwards, the controller transmits the tilt angle value and tilt direction to the handheld remote control. The operator can read the tilt status of the main beam 1 intuitively through the screen of the remote control. The operator compares the real-time tilt angle with the allowable range specified by the process. If the tilt value exceeds the threshold, the operator sends a displacement control signal through the remote control. Afterwards, the remote control signal is transmitted back to the controller, and the controller outputs action commands to the corresponding drive components 3 at both ends of the main beam 1. The drive component 31 drives the hoisting component 2 to move along the slide groove 11 of the main beam 1, adjusting the relative distance between the two sets of hoisting points. Finally, during the adjustment process, the tilt sensor continuously transmits angle data back to the controller, and the data is synchronously refreshed to the remote control in real time. The operator continuously fine-tunes the position of the lifting point based on the feedback until the remote control displays that the tilt angle of the main beam 1 has fallen back to the specified safe range. The operator then stops outputting adjustment commands, and the position of the lifting point is fixed.

[0061] It should be noted that during the entire lifting point leveling process, the overhead crane maintains a slow lifting speed, and the lifting point adjustment and workpiece lifting are carried out simultaneously, without the need to lower the entire lifting equipment to a low position; after the tilt angle reaches the standard, the overhead crane continues to lift, completing the complete lifting of the object.

[0062] For automatic suspension point adjustment mode: First, after the hoisting preparation is completed, the operator switches the handheld remote control to automatic adjustment mode, controls the overhead crane to drive the lifting equipment to rise slowly, and the sling gradually carries the workpiece; Subsequently, the tilt sensor collects the tilt angle of the main beam 1 in real time and continuously uploads it to the controller. The controller has a pre-stored tilt angle safety threshold and automatically compares the real-time angle with the standard range. If the tilt angle of the main beam 1 exceeds the specified range, the controller directly sends an action command to the drive components 3 at both ends, driving the hoisting component 2 to automatically move along the slide 11 and change the distance between the two hoisting points to correct the levelness of the main beam 1. When the tilt angle of the main beam 1 is detected to have entered the standard range, the controller automatically stops the drive component 3 and locks the current hoisting point position to prevent sliding and displacement. Subsequently, the entire automatic lifting point correction process is synchronized with the slow lifting of the overhead crane, requiring no manual observation or adjustment. After leveling is completed, the overhead crane continues to lift, achieving complete lifting of the object. At the same time, the automatic adjustment mode links the pressure sensor inside the lifting assembly 2 to synchronously monitor the load on both sides. If the pressure on one side of the lifting point exceeds the standard and leveling cannot be completed for an extended period, the controller will immediately stop the machine and issue an audible and visual alarm to prevent workpiece deformation due to uneven load and damage to the tooling. Finally, all tilt angle, load, and lifting point position data are automatically stored in the controller, which can be connected to the workshop's digital assembly system to achieve traceability of lifting process data.
