Description

Technical Field

[0001] This invention belongs to the field of bridge construction technology, and more specifically, relates to a device and method for processing the plane of a large cross-section segment end plate. Background Technology

[0002] The connection between the steel shell tower and the crossbeam is the core of the load-bearing system of the main tower structure of a bridge. Its design must comprehensively consider the requirements of stress stability, construction feasibility, and long-term durability. In traditional technical solutions, this connection often adopts a beam joint welding connection mode. Although it can achieve basic load-bearing function, it has limitations such as stress concentration due to welding residual stress, high requirements for on-site welding conditions, and difficulty in later maintenance. With the increasing demand for the construction of ultra-long span bridges, through structural innovation and process optimization, the industry has developed a new connection scheme of "pressure plate + prestressed steel strands", which breaks through the technical bottleneck of traditional welding anchoring. This new scheme sets an annular pressure plate on the outer wall of the steel shell tower column, so that the end of the crossbeam forms a rigid contact surface with the pressure plate. Then, the prestressed steel strands penetrating the tower column apply pre-tension, realizing the direct transfer of load through the contact surface. This not only simplifies the internal stress structure of the tower column, but also ensures the safe and efficient construction of the main tower system of ultra-long span bridges. However, this pressure-bearing force transmission mode places stringent requirements on the precision of the connection interface. The beam end plate must meet a flatness tolerance standard of 1mm / whole plane (flatness refers to the deviation of the macroscopic unevenness of the substrate relative to the ideal plane; the tolerance zone consists of two parallel planes, and the controlled element must be located between them). However, after processes such as raw material cutting, segment assembly, welding, and straightening, the actual flatness deviation of the end plate is usually around 4mm, which is far from meeting the installation requirements and must be corrected through precision machining.

[0003] Currently, due to limitations imposed by previous engineering design concepts and construction needs, the industry has not yet developed a demand for machining large cross-sections of such components. Traditional connection methods have lower precision requirements and do not require complex machining, resulting in a long-standing lack of large-section machining technologies and specialized methods suitable for steel shell tower beam end plates. While the construction industry has a demand for machining large planes such as the connection ends of large steel columns and beams (some single planes can reach tens of square meters), existing machining relies on large fixed boring and milling machines and gantry milling machines. These machines are bulky, difficult to transport and install, have poor adaptability to workpiece size and shape, and are strictly limited by processing sites, leading to high processing costs. Although the machinery industry possesses mature processes for machining large planes of regular parts such as large machine tool beds and press worktables, the objects being machined are mostly regularly shaped components with stable processing environments. Their fixed machining equipment is ill-suited for irregular large workpieces like steel shell tower beam end plates, and cannot meet the dynamic machining needs of construction sites. Summary of the Invention

[0015] According to a second aspect of the present invention, a method for machining the plane of a large-section segment end plate is provided, which is implemented using the aforementioned large-section segment end plate plane machining apparatus, and includes the following steps: S100: The steel shell tower crossbeam segment is turned into a vertical state by using lifting equipment. Platform connection components are pre-welded to the side wall of the steel shell tower crossbeam segment. The side platform is fixedly installed on the side wall of the steel shell tower crossbeam segment through the platform connection components. The corner platform is welded between the two side platforms to form a ring-shaped outer construction channel. Inclined ladders are erected on the opposite side walls of the steel shell tower crossbeam segment to lift the platform inside the warehouse into the box chamber of the steel shell tower crossbeam segment and fix it to the bottom of the box chamber. S200: Using the construction channel, the support leveling components, lateral movement components, longitudinal movement components, vertical movement components, and processing components are sequentially installed on the steel shell tower beam segment; S300: The reference return line method is used to measure the inclination angle of the end plate of the steel shell tower crossbeam segment. A high-precision three-dimensional laser scanner is used to scan the plane of the end plate of the steel shell tower crossbeam segment to obtain the three-dimensional point cloud data of the end plate, which is used to detect the overall flatness of the end plate and then determine the milling angle and milling amount of the end plate. S400: Based on the measurement results of the flatness and tilt angle of the end plate, adjust the horizontal height of the first slide rail by supporting the leveling component so that the plane of the first slide rail is parallel to the plane of the end plate according to the design standard; S500: By controlling the first drive motor, the second drive motor and the third drive motor, the position of the processing components in the horizontal, vertical and longitudinal directions is adjusted to perform precise milling operations on the end plates of the steel shell tower crossbeam segments. S600: After the milling of the steel shell tower crossbeam segment is completed, the inclination angle and overall flatness of the end plate are checked using the reference return line method and a high-precision 3D laser scanner as described in step S300. If the requirements are not met, the end plate of the steel shell tower crossbeam segment needs to be milled again using the machining components until the inclination angle and overall flatness of the end plate meet the design standard requirements. S700: Once the tilt angle and overall flatness of the end plate meet the design standard requirements, the processing mechanism, inclined ladder, indoor platform, corner platform and side platform are removed in sequence. Then, the steel shell tower crossbeam segment is smoothly reversed to the normal installation posture using lifting equipment to complete the entire processing process.

[0016] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: 1. The present invention discloses a large-section segment end plate planar processing device, which adopts a modular combination structure of "platform pre-welded parts + side platform + corner platform + warehouse indoor platform". The structure is divided into independent modules of steel shell tower crossbeam segments, platform connecting components, side platforms, corner platforms and warehouse indoor platforms, which improves the versatility and transportation convenience of the construction platform. The platform connecting components installed on the four side walls of the steel shell tower crossbeam segments are bolted to the side platforms, and the corner platforms set at the four corners are fixedly connected to the side platforms to form a surrounding external construction channel. The warehouse indoor platform inside the box provides a working surface for the internal processing of the segment, realizing full coverage of the internal and external construction space of the segment, and providing convenient conditions for the measurement and processing of the end plates of the steel shell tower crossbeam segments.

[0017] 2. The present invention provides a large-section segment end plate planar processing device, which, by controlling the first drive motor, the second drive motor and the third drive motor, adjusts the position of the processing component in the transverse, longitudinal and vertical directions respectively, and can perform precise milling operations on the end plate of the steel shell tower crossbeam segment 1. The independent control and coordinated cooperation of the three drive motors in the three directions establish a complete three-dimensional motion adjustment system. The transverse drive can cover the width range of the end plate, the longitudinal drive can adapt to the length extension of the end plate, and the vertical drive precisely controls the milling depth. The combination of the three enables the processing component to perform targeted milling on any area of ​​the end plate.

[0018] 3. The present invention provides a large-section segment end plate planar processing device, which uses a high-precision three-dimensional laser scanner to comprehensively scan the end plate processing surface. The scanner has a measurement accuracy of 0.075mm and a measurement resolution of 0.025mm, and can quickly and completely acquire the three-dimensional point cloud data of the end plate, thereby accurately reflecting the overall planar condition of the end plate. This avoids the data bias caused by traditional local measurement methods. At the same time, combined with the benchmark return line method, the inspection line is marked in reverse from the vertical baseline of the crossbeam segment ring to the crossbeam end plate. This is used as a reference to strictly verify the inclination angle of the end plate, ensuring that the end plate angle meets the design standards. The processing components process the end plate of the steel shell tower crossbeam segment, and the processing flatness can reach 0.5mm / m, which can meet the stringent requirements of fine processing.

This invention, by adopting a modular combination structure of "platform pre-welded parts + side platforms + corner platforms + indoor platform," divides the structure into independent modules: the steel shell tower beam segment 1, platform connecting components 2, side platforms 3, corner platforms 4, and indoor platform 5, thereby improving the versatility and transportation convenience of the construction platform. Platform connecting components 2 installed on the four side walls of the steel shell tower crossbeam segment 1 are bolted to the side platforms 3. Corner platforms 4 set at the four corners are fixedly connected to the side platforms 3, forming a surrounding external construction channel.

A second kick plate 44 is fixedly installed at the bottom of the second railing 45 and is fixedly connected to the upright of the second railing 45. The corner platform 4 is formed by two parallel second horizontal bars 41 and two diagonal connecting bars 42 to create an isosceles trapezoidal frame, which improves the overall load-bearing capacity and deformation resistance of the corner platform walkway. Both the second horizontal bars 41 and the diagonal connecting bars 42 are made of I-beams, further enhancing the structural strength and durability.

The second railing 45 on the outer side of the corner platform walkway and the second kick plate 44 at the bottom constitute a complete protective system, effectively preventing accidental slippage of personnel and the falling of small items, enhancing the safety performance of the platform during use.

[0030] Furthermore, the two ends of the second transverse bar 41 are respectively fixedly connected to the outermost first transverse bar 31 of the two side platforms 3, so that the corner platform 4 is fixedly installed between the two side platforms 3.

[0031] Furthermore, the indoor platform 5 includes multiple support frame components, longitudinal connecting rods 56, second diagonal braces 57, and patterned steel plates 58. Multiple longitudinal connecting rods 56 are fixedly installed between the tops of every two support frame components, and cross-shaped second diagonal braces 57 are fixedly installed between their two sides. Patterned steel plates 58 are provided on the tops of the multiple support frame components and the multiple longitudinal connecting rods 56. The support frame components are connected as a whole by the longitudinal connecting rods 56. The cross-shaped second diagonal braces 57 utilize the principle of triangular stability to enhance the platform's anti-tilting ability and evenly distribute the construction load inside the container. The indoor platform 5 expands the working space inside the container, solving the problems of no operating platform inside the beam container, preventing personnel from entering to inspect processing quality, posing a risk of falls from height, and creating blind spots in processing. The number and layout of the support frame components can be flexibly adjusted according to the container size to adapt to different container structures. In addition, each component can be prefabricated in the factory and quickly assembled on site, reducing the amount of work inside the box. The detachable design facilitates the reuse of the platform, and standardized parts reduce maintenance costs, providing a stable, efficient and safe working platform for the processing of steel shell tower crossbeam segments inside the box.

[0032] Furthermore, the support frame assembly includes vertical support rods 51, horizontal connecting rods 52, bottom connecting rods 53, first diagonal braces 54, and cantilevered diagonal braces 55; wherein, the horizontal connecting rods 52 are cantilevered and fixed to the top of the two vertical support rods 51, the bottom connecting rods 53 are fixedly installed between the bottoms of the two vertical support rods 51, and two first diagonal braces 54 are also provided between the two vertical support rods 51. One end of the two first diagonal braces 54 is fixedly connected to the lower end of the two vertical support rods 51, and the other end is fixedly connected to the upper end of the two vertical support rods 51. The cantilevered end of the horizontal connecting rods 52 is fixedly installed with the vertical support rods 51 with the cantilevered diagonal braces 55. The basic frame is formed by vertical support rods 51 and horizontal connecting rods 52. Bottom connecting rods 53 enhance bottom stability. The first diagonal brace 54, arranged in a cross pattern, uses the principle of triangular rigidity to resist horizontal loads and prevent frame twisting. The cantilevered diagonal brace 55 transfers the load from the cantilevered end of the horizontal connecting rod 52 to the vertical support rod 51, increasing the stability of the cantilevered end of the horizontal connecting rod 52. The cantilever structure of the support frame assembly can adjust the cantilever length according to the size of the enclosure. This can be modified by adjusting the width of the subsequent steel shell tower crossbeam segment 1, reducing the amount of tooling modification required to adapt to enclosures of different sizes. Each component can be prefabricated in the factory and quickly assembled on-site, reducing the amount of high-altitude work inside the enclosure and facilitating transportation and storage.

[0033] Furthermore, the transverse connecting rod 52 is made of I-beams, and the vertical support rod 51, the bottom connecting rod 53, the first diagonal brace 54 and the cantilever diagonal brace 55, the longitudinal connecting rod 56 and the second diagonal brace 57 are all made of angle steel.

[0034] Furthermore, the patterned steel plate 58 is fixedly installed on the top of the transverse connecting rod 52 and the longitudinal connecting rod 56. One end of the cross-shaped second diagonal brace 57 is fixedly connected to the lower end of the vertical support rod 51 in two adjacent support frame assemblies, and the other end is fixedly connected to the upper end of the vertical support rod 51 in two adjacent support frame assemblies. The patterned steel plate 58 forms a continuous rigid working surface, while the cross-shaped second diagonal brace 57 connects adjacent support frame assemblies into a whole. The axial force transmission characteristics of the diagonal brace enhance the platform's resistance to horizontal loads, improving its overall deformation resistance and overturning resistance. The anti-slip texture on the surface of the patterned steel plate 58 reduces the risk of personnel slipping.

[0035] Furthermore, inclined ladders 6 are respectively installed on the two opposite side walls of the steel shell tower beam segment 1. The bottom of the inclined ladder 6 is fixed to the first grid plate 34 on the top of the side platform 3, and its top extends to the top working surface of the steel shell tower beam segment 1, forming a vertically connected personnel passage. This not only provides a convenient passage for construction personnel to go up and down, avoiding the safety hazards of traditional climbing methods, but also ensures the stability of the inclined ladder during use through rigid connection with the side platform 3. It is suitable for high-altitude operation scenarios of the steel shell tower beam segment 1, effectively improving the passage efficiency and operation safety of construction personnel.

[0036] Furthermore, the processing mechanism 7 includes a support and leveling component 71, a lateral movement component 72, a longitudinal movement component 73, a vertical movement component 74, and a processing component 75; wherein, the support and leveling component 71 is fixedly mounted on the web of the opposite sidewall of the steel shell tower beam segment 1, the lateral movement component 72 is fixedly mounted on the top of the support and leveling component 71, the longitudinal movement component 73 is slidably mounted on the top of the lateral movement component 72, the vertical movement component 74 is slidably mounted on the side of the longitudinal movement component 73, and the processing component 75 is fixedly mounted on the side of the vertical movement component 74; the support and leveling component 71 can adjust the horizontal height of the processing mechanism 7 to achieve precise positioning and leveling. The horizontal movement component 72, the vertical movement component 73, and the vertical movement component 74 work together to form a high-precision three-dimensional motion system, which enables the processing component 75 to move precisely in multiple dimensions in space. This effectively expands the processing coverage of the processing component 75, allowing it to operate on a wider range of processing objects, enhancing the applicability of the processing mechanism 7, and improving processing efficiency and quality.

[0037] Further, the support leveling assembly 71 includes a support beam 711, first adjusting pads 712, second adjusting pads 713, adjusting bolts 714, and a track beam 715; wherein, the support beam 711 is fixedly mounted on the web of the opposite sidewall of the steel shell tower crossbeam segment 1, and a plurality of first adjusting pads 712 are fixedly mounted on the top of the support beam 711 along its length direction, and each of the plurality of first adjusting pads 712 is provided with a second adjusting pad 713 on its top, and the first adjusting pads 712 and the second adjusting pads 713 are aligned. Threaded holes are provided at corresponding positions, with the threads in the two holes facing opposite directions. The first adjusting shim 712 and the second adjusting shim 713 are fixedly connected by an adjusting bolt 714. The adjusting bolt 714 is divided into two sections along the axial direction, and the external threads of the two sections match the threaded holes of the first adjusting shim 712 and the second adjusting shim 713, respectively. A track beam 715 is fixedly mounted on the top of the second adjusting shim 713. The support beam 711 is made of I-beam steel, and the track beam 715 is made of U-shaped beam. When the adjusting bolt 714 is turned, because the threads of the adjusting bolt 714 and the two shims turn in opposite directions, the first adjusting shim 712 and the second adjusting shim 713 will move relatively closer or relatively farther away along the axial direction of the adjusting bolt, thereby changing the distance between the support beam 711 and the track beam 715, thus ensuring the levelness of the top surface of the track beam to meet the operating requirements of subsequent components.

[0038] Further, the lateral movement assembly 72 includes a first slide rail 721, a first slider 722, a first rack 723, a first U-shaped connecting plate 724, a first drive motor 725, a first gear 726, a connecting beam 727, a first fixing plate 728, and a second fixing plate 729; wherein, the first slide rail 721 is fixedly installed at the top center of the track beam 715, and two first sliders 722 are slidably connected to the top of the first slide rail 721. The first sliders 722 can slide along the length direction of the first slide rail 721. The top of the two first sliders 722 is fixedly installed with a first fixing plate 728, and the top of the first fixing plate 728 is provided with a connecting beam 727, which is made of a U-shaped beam. The connecting beam 727 has a second fixing plate 729 on its top. The first fixing plate 728 and the second fixing plate 729 have threaded holes at corresponding positions. The connecting beam 727 is fixedly installed on the first fixing plate 728 by bolts passing through the threaded holes on the first fixing plate 728 and the second fixing plate 729. The outer walls of both ends of the connecting beam 727 are fixedly fitted with a first U-shaped connecting plate 724. The first drive motor 725 is fixedly installed inside the first U-shaped connecting plate 724 and has a self-locking function. The output shaft of the first drive motor 725 is fixedly installed with a first gear 726. The top of the track beam 715 is fixedly installed with a first rack 723. The first gear 726 meshes with the first rack 723. The sliding guide structure, formed by the first slide rail 721 and two first sliders 722, along with the rigid load-bearing system formed by the connecting beam 727 bolted together with the first fixing plate 728 and the second fixing plate 729, ensures the straightness accuracy of lateral movement, avoids jamming or deviation during movement, and provides a stable motion reference for the operation of subsequent components. On the other hand, the component adopts a gear and rack transmission method, in which drive motors symmetrically arranged at both ends of the connecting beam 727 drive the first gear 726 to mesh with the first rack 723, enabling the connecting beam 727 to move along the length of the first slide rail 721.

[0039] Further, the longitudinal moving component 73 includes a second slide rail 731, a second slider 732, a second rack 733, a second U-shaped connecting plate 734, a second drive motor 735, and a second gear 736; wherein, two parallel second slide rails 731 are fixedly mounted on the inner sidewall of the connecting beam 727, and a second rack 733 is fixedly mounted on its top. Two second sliders 732 are slidably connected on each second slide rail 731. A vertical moving component 74 is fixedly mounted on the sidewall of the second slider 732. A second U-shaped connecting plate 734 is fixedly mounted on the sidewall of the vertical moving component 74. A second drive motor 735 is fixedly mounted inside the second U-shaped connecting plate 734, and the second drive motor 735 has a self-locking function. A second gear 736 is fixedly mounted on the output shaft of the second drive motor 735, and the second gear 736 meshes with the second rack 733. By employing two parallel second slide rails and corresponding sliders to form a double-rail guide structure, the two second sliders on each slide rail provide multi-point support, effectively controlling the straightness deviation of longitudinal movement, avoiding swaying or offset during movement, and providing stable motion guidance for the vertical moving component. On the other hand, the second drive motor drives the second gear and the second rack to mesh and transmit power, enabling the vertical moving component 74 to move along the length of the second slide rail.

[0040] Specifically, when the second drive motor 735 is started, it drives the second gear 736 to rotate synchronously. As the second gear 736 rotates, it maintains a meshing state with the second rack 733 fixed on the top of the connecting beam 727. The meshing force between the gear tooth profile and the rack tooth profile is converted into a driving force along the length of the rack. Under the action of this driving force, the vertical moving component 74, which is connected to the second drive motor 735 through the second U-shaped connecting plate 734, will drive the second slider 732, which is fixed on its side wall, to slide linearly along the second slide rail 731. Since the two second slide rails 731 are parallel to each other and fixed to the inner side wall of the connecting beam 727, the second slider 732 moves stably in the longitudinal direction under the guide constraint of the slide rail, and finally realizes the longitudinal position adjustment of the vertical moving component 74 and the processing component 75 connected to it.

[0041] Further, the vertical moving assembly 74 includes a base plate 741, a fixed beam 742, a third slide rail 743, a third slider 744, a third drive motor 745, a fixed block 746, a screw 747, a moving seat 748, and a connecting plate 749; wherein, the base plate 741 is fixedly mounted on the side wall of the second slider 732, and the second U-shaped connecting plate is fixedly mounted on the side wall of the base plate 741; fixed beams 742 are fixedly mounted on both sides of the other side wall of the base plate 741, and a third slide rail 743 is fixedly mounted on the side wall of each fixed beam 742; the third slide rail 743 slides upwards. The system has two third sliders 744 connected to each other. Connecting plates 749 are fixedly mounted on the sidewalls of the third sliders 744 on both sides. A third drive motor 745 is fixedly mounted in the middle of the sidewall of the base plate 741, and the third drive motor 745 has a self-locking function. A screw 747 is fixedly mounted on the output shaft of the third drive motor 745. A fixing block 746 is threadedly connected to the other end of the screw 747. The fixing block 746 is fixedly mounted on the sidewall of the base plate 741. A movable seat 748 is threadedly connected to the outer side of the screw 747. The sidewall of the movable seat 748 is fixedly connected to the connecting plate 749. By adopting a threaded transmission structure of screw and movable seat, combined with direct drive by the third drive motor, rotational motion can be efficiently converted into vertical linear motion. The high transmission ratio of the threaded transmission enables fine displacement adjustment and has a self-locking function, ensuring that the processing component maintains its position stably after vertical positioning, meeting the locking requirements of high-precision processing. On the other hand, the third slide rails are symmetrically arranged on both sides of the base plate through fixed beams. Each slide rail is paired with two third sliders to form multi-point support. It is then rigidly connected to the moving seat through the connecting plate, which can evenly distribute the load of the processing components, effectively improve the overturning resistance of the overall structure, avoid swaying or deviation caused by uneven force during vertical movement, and ensure the stability of movement.

[0042] Specifically, the third drive motor 745 is started, and its output shaft drives the screw 747 to rotate synchronously. This drives the movable seat 748, which is threaded to the outside of the screw 747, to move vertically along the axis of the screw 747 under the action of thread engagement. At the same time, the movable seat 748 is fixedly connected to the connecting plate 749 through the side wall, driving the connecting plate 749 to move synchronously. The connecting plate 749 is fixedly connected to the third slider 744 on the third slide rails 743 on both sides. Under the guidance and constraint of the third slide rails 743, the third slider 744 slides vertically along the third slide rails 743, further guiding the movable seat 748 and the connecting plate 749 to maintain a stable vertical trajectory. Through the above transmission, the vertical position of the processing component 75 connected to the connecting plate 749 is precisely adjusted.

[0043] Furthermore, the machining assembly 75 includes a milling motor 751, a gearbox 752, and a milling cutter 753. The output shaft of the milling motor 751 is mounted with the gearbox 752, and the output shaft of the gearbox 752 is mounted with the milling cutter 753. The gearbox 752 is fixedly mounted on the side wall of the connecting plate 749. By driving the gearbox with the milling motor, multiple speed adjustments of the milling cutter can be achieved, which can not only meet the milling requirements of different materials, but also improve cutting efficiency through speed matching, avoiding fluctuations in machining quality caused by a single speed.

[0044] Example 2 Combination Figure 1-12 ,like Figure 13 As shown, this invention provides an installation method for a modular, detachable construction platform for segment processing, implemented using the aforementioned modular, detachable construction platform for segment processing. The specific steps are as follows: S100: The steel shell tower crossbeam segment 1 is turned into a vertical state by using lifting equipment. The platform connecting component 2 is pre-welded to the side wall of the steel shell tower crossbeam segment 1. The side platform 3 is fixedly installed on the side wall of the steel shell tower crossbeam segment 1 through the platform connecting component 2. The corner platform 4 is welded between the two side platforms 3 to form a surrounding external construction channel. The inclined ladder 6 is erected on the opposite side wall of the steel shell tower crossbeam segment 1 to lift the inner platform 5 into the box chamber of the steel shell tower crossbeam segment 1 and fix it to the bottom of the box chamber. S200: Using the construction channel, the support leveling component 71, the lateral movement component 72, the longitudinal movement component 73, the vertical movement component 74, and the processing component 75 are sequentially installed on the steel shell tower crossbeam segment 1; S300: The inclination angle of the end plate of the steel shell tower crossbeam segment 1 is measured by the reference return line method. A high-precision three-dimensional laser scanner is used to scan the plane of the end plate of the steel shell tower crossbeam segment 1 to obtain the three-dimensional point cloud data of the end plate, which is used to detect the overall flatness of the end plate and then determine the milling angle and milling amount of the end plate. S400: Based on the measurement results of the flatness and tilt angle of the end plate, the horizontal height of the first slide rail 721 is adjusted by supporting the leveling component 71 so that the plane of the first slide rail 721 is parallel to the plane of the end plate according to the design standard. S500: By controlling the first drive motor 725, the second drive motor 735 and the third drive motor 745, the position of the processing component 75 in the horizontal, longitudinal and vertical directions is adjusted to perform precise milling operations on the end plate of the steel shell tower crossbeam segment 1. S600: After the milling of the steel shell tower crossbeam segment 1 is completed, the inclination angle and overall flatness of the end plate are checked using the reference return line method and a high-precision three-dimensional laser scanner as described in step S300. If the requirements are not met, the end plate of the steel shell tower crossbeam segment 1 needs to be milled again using the processing component 75 until the inclination angle and overall flatness of the end plate meet the design standard requirements. S700: Once the tilt angle and overall flatness of the end plate meet the design standard requirements, the processing mechanism, inclined ladder 6, indoor platform 5, corner platform 4 and side platform 3 are dismantled in sequence. Then, the steel shell tower crossbeam segment 1 is smoothly reversed to the normal installation posture using lifting equipment to complete the entire processing process.

[0045] Furthermore, the reference line method involves drawing a design reference line on the side of the end plate of the steel shell tower beam segment 1. The reference line should be perpendicular to the vertical direction of the steel shell tower beam segment 1. Then, the distance between the reference line and the top edge of the end plate is measured, and the actual tilt angle of the end plate is calculated through geometric conversion. By comparing the calculated actual tilt angle with the design tilt angle, it can be determined whether the current angle of the end plate meets the construction requirements. The design tilt angle is predetermined according to the project requirements and is used to ensure the structural accuracy and stability of the steel shell tower beam segment 1 after installation.

[0046] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
