Description

Technical Field

[0001] This invention belongs to the field of medical pendant technology, specifically relating to a construction method for an ICU pendant. Background Technology

[0002] Medical pendant systems are essential gas supply equipment in modern hospital operating rooms, primarily used for the terminal transfer of medical gases such as oxygen, suction, compressed air, and nitrogen. They feature motor-controlled platform lifting, ensuring safety and reliability; a balanced design guarantees platform level and equipment safety; motor drive ensures fast and efficient operation; and robust design and manufacturing, along with composite material surfaces that can be cleaned with standard disinfectants, completely eliminate the risk of contamination. Pendant systems are typically fixed to the roof using supports located between the roof and ceiling. When a pendant requires two supports for fixation, the installation and positioning of these supports on the roof becomes inconvenient, affecting construction progress and quality. Furthermore, current technology often uses direct welding to fix the supports to the roof. While welding ensures structural strength, it hinders the installation and disassembly of the supports. Summary of the Invention

[0003] The purpose of this invention is to provide a technical solution for the construction of an ICU pendant tower, addressing the shortcomings of existing technologies. The structure is ingeniously and rationally designed, mapping the positioning points on the roof to auxiliary points on the ground. Combined with the design of auxiliary supports, the base's positioning is directly adjusted based on these ground-based auxiliary points and the support structure. This positioning and adjustment process is performed directly below ground, eliminating the need for high-altitude positioning and adjustment work, making the overall construction more convenient and simple. It also ensures precise positioning between the adjusted base and the positioning points, thereby guaranteeing the actual construction quality. Furthermore, the base is fixed to the roof's fixed structural layer using expansion bolts, ensuring both installation stability and ease of installation and disassembly. The installation positions of the expansion bolts on the roof's fixed structural layer are precisely assisted by pre-set mounting holes on the base, improving positional accuracy and making the base installation more secure and reliable.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An ICU pendant construction method includes the following steps:

[0006] 1. Measurement and positioning:

[0007] (1) Draw construction drawings based on the actual site survey and the dimensions of the tower, determine the installation positions of the two bases on the fixed structure layer of the roof, and mark the positioning points;

[0008] (2) Use a vertical measuring rod to determine the positions of two auxiliary points on the ground corresponding to the two positioning points, and draw an auxiliary straight line between the two auxiliary points, with the two ends of the auxiliary line connecting the two auxiliary points.

[0009] The construction process is ingenious. The positioning points of the two bases on the fixed structural layer of the roof are mapped to the ground to form two auxiliary points. The line connecting the two auxiliary points is drawn as an auxiliary straight line. The auxiliary points and auxiliary straight line facilitate the subsequent positioning and adjustment of the auxiliary support, thereby ensuring the accurate positioning between the base and the positioning point. The entire positioning and adjustment is carried out below the ground, which is more convenient for actual construction work and more conducive to controlling the construction accuracy and quality.

[0010] 2. Positioning of the auxiliary support:

[0011] (1) The auxiliary support includes a positioning base, a lifting assembly, and an adjusting support. The positioning base is selected according to the base size, and then installed between the positioning base and the lifting assembly. The lifting assembly includes a fixed base plate, a lifting column, and a lifting support platform. The lifting column is fixed to the fixed base plate, and its top end is connected to the lifting support platform. The positioning base and the lifting support platform are then installed and fixed together, forming a combined frame. The positioning base and the lifting assembly are detachable, allowing for the selection of a corresponding positioning base based on different base sizes. This enables positioning and lifting operations on different bases. The design is ingenious and reasonable, and the positioning base is replaceable. To expand the applicability of the auxiliary support, it can be used for the installation of tower cranes of different sizes. The lifting column can realize the automatic lifting operation of the lifting support platform, thereby automatically adjusting the height of the base, so that the base can be moved to the fixed structure layer of the roof for actual installation. It is practical and reasonable, and the lifting operation is automated, making construction more convenient. Multiple lifting columns can be set up and evenly distributed on the fixed base plate and the lifting support platform. Through the joint lifting and support of multiple lifting columns, the overall load-bearing capacity of the lifting support platform is better, the structure is more stable and reliable, and it is more conducive to the stable support of the auxiliary support for the base, thus improving safety.

[0012] (2) The combined frame is installed onto the adjusting support base. The adjusting support base includes a sliding support plate and a movable support base. The sliding support plate is slidably snapped onto the movable support base. In the initial state, the sliding support plate is fixed against one end of the movable support base. The combined frame is installed onto the sliding support plate. The fixed base plate is embedded into the locating groove in the center of the sliding support plate. The fixed base plate and the sliding support plate are fixed together with screws to form an auxiliary support. The design is ingenious. In the initial state, the sliding support plate is directly limited and fixed at one end of the movable support base, which facilitates the subsequent movement and adjustment of the sliding support plate according to the positioning point of the next base. When the combined frame composed of the positioning base and the lifting component is installed with the adjusting support base, the initial snapping and positioning are achieved through the locating groove. The fixed base plate is matched and embedded into the locating groove. The fixed base plate and the adjusting support base are further fixed together with screws to effectively ensure the assembly is firm and reliable.

[0013] (3) The bottom of the movable support base is equipped with casters with brakes. A handrail is also provided on the movable support base. The handrail is ergonomically designed, facilitating the movement of the auxiliary support. By pushing the handrail, the casters allow the auxiliary support to move as a whole, moving it along the auxiliary straight line until the side of the movable support base with the scale markings aligns vertically with the auxiliary straight line. The position of the auxiliary support is then adjusted along the auxiliary straight line until the endpoint of the measuring rod on the corresponding side of the sliding support plate aligns vertically with one of the auxiliary points. The other auxiliary point is hidden below the side of the movable support base. The clever design of the casters at the bottom of the movable support base facilitates its movement on the ground, enabling the overall movement of the auxiliary support. Moving the auxiliary support allows the sliding support plate to... Precise positioning is achieved between corresponding positioning points. The movable support, lifting components, and positioning base are assembled and set coaxially. The base, which is finally installed on the positioning base, is also set coaxially with the positioning base. The positioning point is the installation center point of the base on the fixed structure layer of the roof. The positioning point corresponds to the auxiliary point on the ground. The position between the sliding support plate and the auxiliary point is adjusted by moving the auxiliary bracket, so as to achieve indirect positioning adjustment between the base and the positioning point. In actual adjustment, the side where the scale is located is first aligned with the auxiliary straight line vertically. The scale direction is the movement direction of the sliding support plate on the movable support. The measuring end point of the measuring rod is located at the scale and is exactly flush with the side of the corresponding scale. This makes it easy to control the initial positioning between the sliding support plate and the auxiliary point through the measuring end point of the measuring rod.

[0014] (4) Insert the telescopic guide rod into the auxiliary hole in the center of the positioning base, extend the telescopic guide rod so that the positioning head at the top of the telescopic guide rod touches the fixed structure layer of the roof, move the adjustment support along the vertical direction of the auxiliary line so that the auxiliary point gradually moves to the bottom of the auxiliary bracket until the positioning head at the top of the telescopic guide rod moves to the positioning point of one of the bases, lock the universal wheel brake and fix it, and use the positioning holes at both ends of the moving support to further fix the entire auxiliary bracket to the ground, and then remove the telescopic guide rod; after the sliding support plate is initially positioned with the auxiliary point, insert the telescopic guide rod to assist in the subsequent position adjustment, and move the sliding support plate to the level of the auxiliary line. In the case of a straight line, the auxiliary support bracket is moved and adjusted vertically along the auxiliary line so that the positioning head of the telescopic guide rod moves exactly to the corresponding positioning point. The auxiliary point and the positioning point cooperate with each other to achieve one-time adjustment and positioning of the auxiliary support bracket. During the successive installation of the two bases, there is no need to adjust the auxiliary support bracket. When the positioning head of the telescopic guide rod moves exactly to the corresponding positioning point, the auxiliary support bracket moves into place. The brakes on the casters limit and fix the entire auxiliary support bracket. Furthermore, the positioning holes can be used to further fix the adjustment support base to the ground, effectively ensuring the stability and reliability of the auxiliary support bracket after it has moved into place, and preventing the auxiliary support bracket from shifting during the subsequent installation and adjustment of the bases.

[0015] 3. Installation of the base:

[0016] (1) The base includes a main frame and supporting diagonal braces. Four supporting diagonal braces are evenly distributed on the four sides of the main frame. Reinforcing diagonal braces are provided on all four sides of the main frame. The main frame includes a bottom frame, side ribs, and a top frame. The corresponding corners of the bottom frame and the top frame are fixedly connected by side ribs. The two ends of the reinforcing diagonal braces are fixed to the corresponding side ribs. The bottom end of the supporting diagonal braces is fixed to the bottom frame. The mounting plate with positioning screws is slid into the slot at the top of the top frame, ensuring that the positioning screws face downwards. The mounting plate is then temporarily fixed in the middle of the base by binding ropes. The base structure is designed to be sturdy and reliable. The side ribs are welded to the bottom frame and the top frame to form a whole, and then reinforcing diagonal braces are welded to the four sides of the main frame. The reinforced diagonal braces further enhance the overall structural strength and stability of the base. Supporting diagonal braces are also installed on the four sides of the main frame. The top of the main frame and the top of the supporting diagonal braces are both firmly attached to the roof's fixed structural layer, ensuring sufficient contact area between the base and the mounting surface. Furthermore, the base is fixed to the mounting surface from multiple installation points, effectively ensuring the base's stability on the roof's fixed structural layer. This results in better overall load-bearing capacity and a safer, more reliable structure. Before placing the base on the positioning base, the mounting plate is slid in from the top of the top frame, and the positioning screws and side ribs are initially secured with binding ropes. This initial fixation of the positioning plate within the main frame ensures that the mounting plate and positioning screws do not obstruct subsequent processes.

[0017] (2) The base that slides into the mounting plate is limited and installed on the positioning base. Since the sliding support plate is precisely positioned with one of the positioning points after adjustment, the precise positioning of the base and the positioning point is achieved by placing the base on the positioning base.

[0018] (3) When the lifting column is started, the lifting column pushes the lifting support platform to move up, and the lifting support platform drives the positioning base to move up synchronously, thereby driving the base installed on the positioning base to move up synchronously until the top surface of the base touches the roof fixed structure layer; the lifting operation is automated, the lifting column lifts to realize the adjustment of the base height, so that the base, which is precisely positioned with the positioning point, moves to the roof fixed structure layer, realizing the precise positioning of the base on the roof fixed structure layer.

[0019] (4) The top surface of the top frame is provided with an expansion panel, and the top of the supporting diagonal rod is provided with an extension plate. The top surface of the extension plate is flush with the top surface of the expansion panel. Mounting holes are pre-set on both the expansion panel and the extension plate. Mark the drilling positions on the roof fixed structure layer from the corresponding mounting holes. Start the lifting column, and the lifting column will drive the base to descend a certain height, leaving space for drilling operations above. Then, drill holes at the drilling positions according to the size of the expansion bolts, install the embedded parts into the holes, and then start the lifting column to drive the base to move up until the top surface of the base touches the roof fixed structure layer. Screw in the expansion bolts to fix the base to the roof fixed structure layer. When the base is installed and positioned on the roof fixed structure layer, the expansion panel and the extension plate are attached to the roof fixed structure layer. Attached to the roof fixed structure layer, the expansion panel and extension plate are pre-set with mounting holes. The mounting holes are used to fix the base to the roof fixed structure layer. The mounting holes on the base are used to locate the drilling position, which effectively ensures the drilling accuracy and makes it easier to install and fix the base to the roof fixed structure layer. After the drilling position is determined, the base is lowered to a certain height to leave space for drilling operation above. After drilling is completed, the base is moved up and fixed to the roof fixed structure layer with the expansion bolts. The design is ingenious and reasonable, and the construction is convenient and reasonable. The drilling position is determined by the pre-set mounting holes on the workpiece, which improves the drilling accuracy and makes the actual installation operation easier.

[0020] (5) After the installation and fixing of a base is completed, the base is loosened from the positioning base, and then the lifting column is started. The lifting column descends and drives the positioning base to move down synchronously through the lifting support platform until the lifting column descends to the limit position, so that the positioning base and the base are completely separated. After the base and the positioning base are loosened, the lifting column drives the positioning base to completely separate from the base, thus completing the installation of a base. The design is reasonable and the construction is convenient and simple.

[0021] (6) Adjust the sliding support plate according to the design spacing between the two positioning points, move the sliding support plate along the moving support seat, and accurately control the moving distance of the sliding support plate with the measuring rod on the side of the sliding support plate and the scale on the moving support seat so that the distance between the measuring rod in the initial state and the measuring rod after the movement is equal to the design spacing between the two positioning points. Then lock the sliding support plate and repeat the process of step (1) to step (5) of step 3 to complete the installation and fixing of the next base. After a base is completed, there is no need to move and adjust the auxiliary support. Just adjust the position of the sliding support plate along the moving support seat so that the sliding support plate moves to the other positioning point for precise positioning. The positioning standard is controlled according to the moving distance of the measuring rod to ensure that the length distance between the scale before the measuring rod moves and the scale after the movement is equal to the distance between the two positioning points. This ensures that the sliding support plate moves to the position. Then lock the sliding support plate to ensure that the sliding support plate cannot move after it moves to the position. Repeat the installation process of the first base. The positioning adjustment is convenient and simple, which is more conducive to actual construction operations.

[0022] 4. Installation of the crane tower:

[0023] (1) The gantry includes a crossbeam and functional components. The functional components are slidably engaged on the sliding track of the crossbeam. The top of the crossbeam is provided with a connecting plate corresponding to the two bases.

[0024] (2) Loosen the binding rope and move the mounting plate downward until it is in contact with the bottom frame. Weld the mounting plate to the bottom frame and fix it in place. The positioning screw on the mounting plate extends out of the bottom frame. First, screw two clamping nuts into the positioning screw. Adjust the position of the uppermost clamping nut so that it rotates and contacts the bottom surface of the mounting plate. Then weld the clamping nut to the mounting plate. The structure is cleverly designed. If the mounting plate is fixed in the bottom frame first, it will affect the installation positioning between the base and the positioning base. Therefore, the mounting plate is initially fixed to the base by binding rope. After the base is installed, loosen the binding rope and move the mounting plate to the bottom frame. Then weld the mounting plate to the bottom frame to ensure the installation is firm. At the same time, a clamping nut is set at the connection end between the positioning screw and the mounting plate. The clamping nut and the positioning screw are threaded together. The clamping nut and the mounting plate are welded together to improve the structural firmness and structural strength at the connection end between the positioning screw and the mounting plate, so that the overall load-bearing capacity is better.

[0025] (3) Install the crossbeam, align the two connecting plates on the crossbeam with the two bases. The connecting plates are provided with connecting holes. The end of the positioning screw extends through the corresponding connecting hole. Then screw a clamping nut into the positioning screw. Adjust the position of the two lowest clamping nuts on the positioning screw. The two lowest clamping nuts limit and fix the connection plate and the positioning screw, thus realizing the installation and fixation between the crossbeam and the base. When installing the crossbeam and the base, align the connecting plate with the base, insert the positioning screw into the corresponding connecting hole on the connecting plate, and then use the two clamping nuts to limit and fix the connecting plate on the positioning screw, thus realizing the installation and fixation between the crossbeam and the base. The design is reasonable, and the installation and disassembly are convenient and simple, which is convenient for subsequent inspection and maintenance.

[0026] (4) Slide the functional components from both ends of the crossbeam onto the sliding guide rail. The crossbeam has corresponding end caps. When installing the functional components, remove the end caps from the crossbeam, slide the functional components onto the sliding guide rail of the crossbeam, and stop the functional components in a reasonable position. After completing the assembly between the functional components and the crossbeam, install the end caps back onto the crossbeam.

[0027] Furthermore, in step (1) of step 2, the installation steps of the positioning base and the lifting support platform are as follows:

[0028] ① A support column one is set at the center of the top surface of the lifting support platform. A positioning rod is set on the support column one. A support column two is set at the center of the bottom surface of the positioning base. A positioning slot is set on the support column two. The positioning slot matches the positioning rod. Support rods are set at all four corners of the top surface of the lifting support platform. Positioning sleeves are set at all four corners of the bottom surface of the positioning base. The positioning sleeves match the support rods one by one.

[0029] ② Install the positioning base above the lifting support platform so that the positioning rod is inserted into the positioning slot and the positioning sleeve is put on the corresponding support rod. Press down and tap the positioning base, and then use the bolt assembly to fix the positioning sleeve and the support rod in place.

[0030] During installation between the positioning base and the lifting support platform, the positioning slot and positioning rod achieve the center positioning and insertion of the positioning base and the lifting support platform, while the support rod and positioning sleeve achieve the positioning and insertion between the four sides of the positioning base and the lifting support platform. Thus, the positioning rod and positioning slot, and the support rod and positioning sleeve achieve precise installation and positioning of the positioning base and the lifting support platform. The support rod and positioning sleeve are further installed by bolt assembly, effectively ensuring the installation firmness and reliability between the positioning base and the lifting support platform.

[0031] Furthermore, reinforcing ribs are provided between support column one and the lifting support platform, and between support column two and the positioning base. The design of the reinforcing ribs enhances the connection strength between support column one and the lifting support platform, and between support column two and the positioning base, making the structure of the positioning base and the lifting support platform more robust and reliable.

[0032] Furthermore, in step (2) of step 3, the installation steps of the base and the positioning base are as follows:

[0033] ① A positioning protrusion is provided at the center of the positioning base. Four positioning blocks and four support blocks are provided on the positioning base. The four positioning blocks and four support blocks are evenly distributed at intervals.

[0034] ② Place the base onto the positioning base, ensuring that the slots on the bottom surface of the base frame match the positioning protrusions. The positioning protrusions engage with the slots, and the four corners of the bottom of the main frame are precisely locked into the four positioning blocks. Simultaneously, the four support diagonal rods on the base are precisely locked into the slots of the four support blocks. The positioning protrusions engage with the slots on the base frame, achieving locking and limiting between the base and the positioning base. The positioning blocks lock and limit the four corners of the main frame, further improving the stability of the base on the positioning base. At the same time, the support blocks provide auxiliary support for the support diagonal rods, making the base more securely placed on the positioning base, facilitating subsequent lifting and lowering operations, and improving operational safety.

[0035] ③ Two inner limit blocks are diagonally arranged on the positioning protrusion. The positioning protrusion has two movable adjustment grooves. The inner limit blocks slide and limit within their corresponding movable adjustment grooves. Moving the inner limit blocks along the movable adjustment grooves gradually moves them to engage with the corresponding side rib. Then, the inner limit blocks are fixed to the positioning blocks located on the side rib. The positioning blocks have positioning pins, and the inner limit blocks have opening slots. When the inner limit blocks move along the movable adjustment grooves and engage with the side rib, the positioning pins also engage with the opening slots. After the inner limit blocks and side rib are properly engaged, a clamping nut is screwed into the top of the positioning pin and tightened. The two inner limit blocks are symmetrically arranged, ensuring that the final two... The inner limit block can be precisely locked onto the two diagonally positioned side ribs on the main frame, further locking from inside the bottom frame. This installation and fixation of the inner limit block and the corresponding positioning block effectively ensures the stability and reliability of the bottom frame on the positioning base, preventing swaying or tilting during the lifting operation of the lifting column, thus improving operational safety. When installing the inner limit block and the positioning block, as the inner limit block moves and engages with the corresponding side rib, it gradually engages with the positioning post on the corresponding positioning block through the opening slot. The clamping nut then tightens and secures the installation, ensuring a firm connection between the inner limit block and the positioning block. The design is reasonable, and installation and disassembly are convenient and simple.

[0036] Furthermore, in step (5) of step 3, the loosening steps between the base and the positioning base are as follows: unscrew the clamping nut, and then move the two inner limit blocks towards the center of the positioning protrusion along the moving adjustment groove, so that the inner limit blocks are completely separated from the corresponding side rods, and the inner limit blocks are completely moved above the positioning protrusion. After the base and the roof fixed structure layer are installed, the inner limit blocks need to be separated from the base, and the clamping nut is removed to facilitate the movement adjustment of the inner limit blocks, so that the movement of the inner limit blocks will not affect the lifting operation of the positioning base.

[0037] Furthermore, the movable adjustment groove includes a vertically connected movable groove section one and a movable groove section two. A dovetail slider is provided at the bottom of the inner limiting block. The movable groove section two matches the dovetail slider. When the inner limiting block slides within the movable groove section two, the dovetail slider slides and engages within the movable groove section two. The dovetail slider is provided with a locking groove. A locking protrusion is provided within the movable groove section one, and the locking protrusion matches the locking groove. When the inner limiting block slides within the movable groove section one, the dovetail slider slides and engages within the movable groove section one. Simultaneously, the dovetail slider slides and engages with the locking protrusion via the locking groove. The structural design is ingenious and reasonable. The design of the dovetail slider ensures that the inner limiting block is limited in its sliding within the movable groove section two, preventing the inner limiting block from detaching from the movable groove section two. The ingenious design of the locking protrusion and locking groove ensures that the inner limiting block is always restricted by the locking protrusion when sliding within the movable groove section one, preventing the inner limiting block from detaching from the movable groove section one.

[0038] Furthermore, in step (6) of step 3, the locking step of the sliding support plate includes:

[0039] ① Two adjustment frames are symmetrically arranged on the movable support base. The top surface of the adjustment frames is marked with a scale. An adjustment groove is formed between the two adjustment frames and the movable support base. The sliding support plate is slidably engaged in the adjustment groove. Two measuring rods are symmetrically arranged on the sliding support plate, with each measuring rod corresponding to one of the two adjustment frames. The structure is compact and reasonable. Both adjustment frames are marked with a scale. Combined with the design of the two measuring rods, the scale can be read from both sides, making the actual adjustment operation more convenient. Moreover, the scale readings on both sides can be mutually verified, improving the accuracy of the adjustment operation and avoiding adjustment errors.

[0040] ② A limit rod is provided on the sliding support plate. The limit rod slides and engages within the adjustment frame. A guide rod is also provided at the end of the limit rod, extending outwards from the outside of the adjustment frame. A locking nut is provided at the extended end of the guide rod. When the sliding support plate moves into position along the adjustment groove, the locking nut is tightened to fix the sliding support plate and the movable support seat. The sliding support plate slides within the two adjustment frames via the limit rod, ensuring the horizontality and reliability of the sliding support plate during movement. A guide rod is also provided on the limit rod, extending outwards from the corresponding adjustment frame. The guide rod, in conjunction with the locking nut, fixes the sliding support plate to the movable support seat. When the sliding support plate needs to be moved, the locking nut is loosened; when the sliding support plate moves into position, the locking nut is tightened. The structure is ingeniously designed and easy to use and adjust.

[0041] Furthermore, in step (2) of step 2, after the assembly frame is installed on the adjusting support, the auxiliary guide components are installed:

[0042] ① The auxiliary guide components include guide posts, sliding sleeves, and retaining sleeves. The guide posts are fixedly mounted on the sliding support plate and are symmetrically distributed on both sides of the lifting support platform. Each guide post has a sliding sleeve mounted on it, and a connecting rod is provided on the sliding sleeve. Each sliding sleeve is connected to a retaining sleeve through the connecting rod.

[0043] ② Fit the ferrule onto the corresponding side of the lifting support platform, move the ferrule along the side of the lifting support platform, and adjust the position of the sliding sleeve connected to the ferrule so that the top of the sliding sleeve's connecting rod is in contact with the bottom surface of the ferrule. Then further adjust the position of the ferrule so that the preset holes on the ferrule correspond one-to-one with the preset holes on the connecting rod. Finally, fix the ferrule and the connecting rod together with screws.

[0044] The auxiliary guide can play a guiding and limiting role. During the lifting operation of the lifting column and the lifting support platform, the lifting column drives the sliding sleeve to slide synchronously along the corresponding guide column through the clamp, which effectively ensures the verticality and stability of the lifting operation, making the entire lifting operation safer and more reliable.

[0045] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0046] This invention features a clever and rational structural design. It maps the positioning points on the roof to auxiliary points on the ground, and with the addition of an auxiliary support, the base's positioning is directly adjusted based on these ground-based auxiliary points. This positioning adjustment process is performed directly below ground, eliminating the need for high-altitude positioning and adjustment work, making the overall construction more convenient and simple. It also ensures precise positioning between the adjusted base and the positioning points, guaranteeing the actual construction quality. Furthermore, the base is fixed to the roof's fixed structural layer using expansion bolts, ensuring both installation stability and ease of installation and disassembly. The expansion bolts' positions on the roof's fixed structural layer are precisely assisted by pre-drilled mounting holes on the base, improving positional accuracy and making the base installation more secure and reliable.

Detailed Implementation

[0064] like Figures 1 to 15 As shown, this invention provides a method for constructing an ICU pendant tower, comprising the following steps:

[0065] An ICU pendant construction method includes the following steps:

[0066] 1. Measurement and positioning:

[0067] (1) Based on the actual site survey and combined with the tower dimensions, draw up construction drawings, determine the installation positions of the two bases 70 on the roof fixed structure layer 26, and mark the positioning points;

[0068] (2) Use a vertical measuring rod to determine the positions of two auxiliary points on the ground corresponding to the two positioning points, and draw an auxiliary straight line between the two auxiliary points, with the two ends of the auxiliary line connecting the two auxiliary points.

[0069] The construction process is ingenious. The positioning points of the two bases 70 on the fixed structural layer 26 of the roof are mapped to the ground to form two auxiliary points. The line connecting the two auxiliary points is drawn as an auxiliary straight line. The auxiliary points and auxiliary straight line facilitate the subsequent positioning and adjustment of the auxiliary support 1, thereby ensuring the accurate positioning between the bases 70 and the positioning points. The entire positioning and adjustment is carried out below the ground, which is more convenient for actual construction work and more conducive to controlling the construction accuracy and quality.

[0070] 2. Positioning of auxiliary support 1:

[0071] (1) The auxiliary support 1 includes a positioning base 2, a lifting assembly 3, and an adjusting support 4. The positioning base 2 is selected according to the size of the base 70, and installed between the positioning base 2 and the lifting assembly 3. The lifting assembly 3 includes a fixed base plate 5, a lifting column 6, and a lifting support platform 7. The lifting column 6 is fixed on the fixed base plate 5, and its top end is connected to the lifting support platform 7. The positioning base 2 and the lifting support platform 7 are then installed and fixed together, forming a combined frame. The positioning base 2 and the lifting assembly 3 are detachable. The corresponding positioning base 2 can be selected according to different base 70 sizes, thus enabling positioning and lifting operations on different bases 70. The design is ingenious and reasonable, and the positioning base 2 is replaceable. Expanding the applicability of auxiliary support 1 allows it to be used for the installation of tower cranes of different sizes. The lifting column 6 enables the automatic lifting of the lifting support platform 7, thereby automatically adjusting the height of the base 70. This allows the base 70 to be moved to the fixed structural layer 26 on the roof for actual installation. This is practical and reasonable, and the automated lifting operation makes construction more convenient. Multiple lifting columns 6 can be set up and evenly distributed on the fixed base plate 5 and the lifting support platform 7 to ensure structural balance and stability. Furthermore, the joint lifting support of multiple lifting columns 6 improves the overall load-bearing capacity of the lifting support platform 7, making the structure more stable and reliable. This is more conducive to the stable support of the base 70 by the auxiliary support 1, thus improving safety.

[0072] The installation steps for the positioning base 2 and the lifting support platform 7 are as follows:

[0073] ① A support column 37 is provided at the center of the top surface of the lifting support platform 7, and a positioning rod 38 is provided on the support column 37. A support column 39 is provided at the center of the bottom surface of the positioning base 2, and a positioning slot 40 is provided on the support column 39. The positioning slot 40 matches the positioning rod 38. Support rods 41 are provided at all four corners of the top surface of the lifting support platform 7, and positioning sleeves 42 are provided at all four corners of the bottom surface of the positioning base 2. The positioning sleeves 42 correspond to the support rods 41 one by one. Reinforcing ribs 44 are provided between the support column 37 and the lifting support platform 7, and between the support column 39 and the positioning base 2. The design of the reinforcing ribs 44 enhances the connection strength between the support column 37 and the lifting support platform 7, and between the support column 39 and the positioning base 2, making the structure of the positioning base 2 and the lifting support platform 7 more robust and reliable.

[0074] ② Install the positioning base 2 above the lifting support platform 7, so that the positioning rod 38 is inserted into the positioning slot 40, and the positioning sleeve 42 is fitted onto the corresponding support rod 41. Press down and tap the positioning base 2, and then use the bolt assembly 43 to fix the positioning sleeve 42 and the support rod 41 together.

[0075] During installation between the positioning base 2 and the lifting support platform 7, the positioning slot 40 and the positioning rod 38 achieve the center positioning and insertion of the positioning base 2 and the lifting support platform 7, and the support rod 41 and the positioning sleeve 42 achieve the positioning and insertion between the four sides of the positioning base 2 and the lifting support platform 7. Thus, the positioning rod 38 and the positioning slot 40, and the support rod 41 and the positioning sleeve 42 achieve precise installation and positioning of the positioning base 2 and the lifting support platform 7. Then, the support rod 41 and the positioning sleeve 42 are further installed by the bolt assembly 43, which effectively ensures the installation firmness and reliability between the positioning base 2 and the lifting support platform 7.

[0076] (2) The combined frame is installed on the adjusting support base 4. The adjusting support base 4 includes a sliding support plate 8 and a movable support base 9. The sliding support plate 8 is slidably snapped onto the movable support base 9. In the initial state, the sliding support plate 8 is fixed against one end of the movable support base 9. The combined frame is installed on the sliding support plate 8. The fixed base plate 5 is embedded into the center slot 10 of the sliding support plate 8. The fixed base plate 5 and the sliding support plate 8 are fixed together with screws 11 to form an auxiliary bracket 1. The design is ingenious. In the initial state, the sliding support plate 8 is directly limited and fixed at one end of the movable support base 9, which facilitates the subsequent movement and adjustment of the sliding support plate 8 according to the positioning point of the next base 70. When the combined frame composed of the positioning base 2 and the lifting component 3 is installed with the adjusting support base 4, the initial snapping and positioning is achieved through the slot 10. The fixed base plate 5 is matched and embedded into the slot 10. The fixed base plate 5 and the adjusting support base 4 are further fixed together with screws 11 to effectively ensure the assembly is firm and reliable.

[0077] After the assembly frame is installed onto the adjusting support base 4, the auxiliary guide component 71 is installed:

[0078] ① The auxiliary guide component 71 includes a guide post 65, a sliding sleeve 66 and a retaining sleeve 67. The guide post 65 is fixedly mounted on the sliding support plate 8 and is symmetrically distributed on both sides of the lifting support platform 7. Each guide post 65 is slidably fitted with a sliding sleeve 66. A connecting rod 68 is provided on the sliding sleeve 66. Each sliding sleeve 66 is connected to a retaining sleeve 67 through the connecting rod 68.

[0079] ② Fit the sleeve 67 onto the corresponding side of the lifting support platform 7, move the sleeve 67 along the side of the lifting support platform 7, and adjust the position of the sliding sleeve 66 connected to the sleeve 67 so that the top of the connecting rod 68 of the sliding sleeve 66 is in contact with the bottom surface of the sleeve 67. Then further adjust the position of the sleeve 67 so that the preset holes on the sleeve 67 correspond one-to-one with the preset holes on the connecting rod 68. Finally, fix the sleeve 67 and the connecting rod 68 together with the screw 11.

[0080] The auxiliary guide 71 can play a guiding and limiting role. During the lifting operation of the lifting column 6 and the lifting support platform 7, the lifting column 6 drives the sliding sleeve 66 to slide synchronously along the corresponding guide column 65 through the sleeve 67, which effectively ensures the verticality and stability during the lifting operation, making the entire lifting operation safer and more reliable.

[0081] (3) The bottom of the movable support base 9 is equipped with universal wheels 12 with brakes, and a handrail 13 is provided on the movable support base 9. The handrail 13 is designed in a user-friendly way to facilitate the movement of the auxiliary support 1. By pushing the handrail 13, the auxiliary support 1 can be moved as a whole through the universal wheels 12, moving the auxiliary support 1 in the direction of the auxiliary straight line until the side of the movable support base 9 with the scale 32 is vertically parallel and coincident with the auxiliary straight line. The position of the auxiliary support 1 is then adjusted along the direction of the auxiliary straight line until the endpoint of the measuring rod 31 on the corresponding side of the sliding support plate 8 is vertically aligned with the position of one of the auxiliary points, while the other auxiliary point is hidden below the side of the movable support base 9. The design is ingenious. The design of the universal wheels 12 under the movable support base 9 facilitates the movement of the movable support base 9 on the ground, realizing the overall movement of the auxiliary support 1. By moving the auxiliary support 1, the sliding support plate 8 can be aligned with the auxiliary support 1. Precise positioning is achieved between corresponding positioning points. The movable support base 9, lifting component 3, and positioning base 2 are assembled and set coaxially. The base 70, which is finally installed on the positioning base 2, is also set coaxially with the positioning base 2. The positioning point is the installation center point of the base 70 on the roof fixed structure layer 26. The positioning point corresponds to the auxiliary point on the ground. The position between the sliding support plate 8 and the auxiliary point is adjusted by moving the auxiliary bracket 1, so as to achieve the indirect positioning adjustment between the base 70 and the positioning point. In actual adjustment, the side where the scale 32 is located is first aligned with the auxiliary straight line vertically. The direction of the scale 32 is the direction of movement of the sliding support plate 8 on the movable support base 9. The measuring end point of the measuring rod 31 is located at the scale 32, and the measuring end point is exactly flush with the side of the corresponding scale 32. This makes it easy to control the initial positioning between the sliding support plate 8 and the auxiliary point through the measuring end point of the measuring rod 31.

[0082] (4) Insert the telescopic guide rod 14 into the auxiliary hole 69 at the center of the positioning base 2, extend the telescopic guide rod 14 so that the positioning head 15 at the top of the telescopic guide rod 14 touches the roof fixed structure layer 26, move the adjustment support 4 along the vertical direction of the auxiliary straight line so that the auxiliary point gradually moves to the bottom of the auxiliary bracket 1 until the positioning head 15 at the top of the telescopic guide rod 14 moves to the positioning point of one of the bases 70, brake and lock the caster wheel 12, and further fix the entire auxiliary bracket 1 to the ground by cooperating with the positioning holes 16 at both ends of the moving support 9, and then remove the telescopic guide rod 14; after the sliding support plate 8 is initially positioned with the auxiliary point, the telescopic guide rod 14 is inserted to assist in the subsequent position adjustment, and the sliding support plate 8 moves to the bottom of the auxiliary bracket 16. With the auxiliary line parallel, the movement and adjustment are carried out along the vertical direction of the auxiliary line so that the positioning head 15 of the telescopic guide rod 14 moves exactly to the corresponding positioning point. The auxiliary point and the positioning point cooperate with each other to achieve one-time adjustment and positioning of the auxiliary bracket 1. During the successive installation of the two bases 70, there is no need to adjust the auxiliary bracket 1. When the positioning head 15 of the telescopic guide rod 14 moves exactly to the corresponding positioning point, the auxiliary bracket 1 moves into place. The brake of the universal wheel 12 limits and fixes the entire auxiliary bracket 1. It can also be used with the positioning hole 16 to further fix the adjustment support base 4 to the ground, effectively ensuring the stability and reliability of the auxiliary bracket 1 after it moves into place, and preventing the auxiliary bracket 1 from shifting during the subsequent installation and adjustment of the base 70.

[0083] 3. Installation of base 70:

[0084] (1) The base 70 includes a main frame 17 and four supporting diagonal braces 18. The four supporting diagonal braces 18 are evenly distributed on the four sides of the main frame 17. The four sides of the main frame 17 are provided with reinforcing diagonal braces 19. The main frame 17 includes a bottom frame 20, side ribs 21 and a top frame 22. The corresponding corners of the bottom frame 20 and the top frame 22 are fixedly connected by the side ribs 21. The two ends of the reinforcing diagonal braces 19 are fixed to the corresponding side ribs 21. The bottom end of the supporting diagonal braces 18 is fixed to the bottom frame 20. The mounting plate 24 with the positioning screw 25 is slid into the slot 23 at the top of the top frame 22, and the positioning screw 25 is set downward. The mounting plate 24 is temporarily fixed in the middle position of the base 70 by the binding rope. The base 70 has a solid and reliable structural design. The side ribs 21 are welded to the bottom frame 20 and the top frame 22 to form the main frame 17. The four sides of the main frame 17 are provided with reinforcing diagonal braces 19. Welded reinforcement diagonal braces 19 are used to further improve the overall structural strength and firmness of the base 70. At the same time, support diagonal braces 18 are set on the four sides of the main frame 17. The top of the main frame 17 and the top of the support diagonal braces 18 are attached and fixed to the roof fixed structure layer 26, which ensures the contact area between the base 70 and the mounting surface. The base 70 is installed and fixed to the mounting surface from multiple installation points, which effectively ensures the installation firmness of the base 70 on the roof fixed structure layer 26, making the overall load-bearing capacity of the base 70 better and the structure safer and more reliable. Before the base 70 is placed on the positioning base 2, the mounting plate 24 is slid in from the top of the top frame 22, and the positioning screw 25 and the side rib 21 are initially tied and fixed with binding ropes to achieve the initial fixation of the positioning plate in the main frame 17, so that the mounting plate 24 and the positioning screw 25 will not hinder the subsequent processes.

[0085] (2) The base 70 that slides into the mounting plate 24 is limited and installed on the positioning base 2. Since the sliding support plate 8 after adjustment is accurately positioned with one of the positioning points, the base 70 is placed on the positioning base 2 to achieve accurate positioning between the base 70 and the positioning point.

[0086] The installation steps for the base 70 and the positioning base 2 are as follows:

[0087] ① A positioning protrusion 45 is provided at the center of the positioning base 2. Four positioning blocks 46 and four support blocks 47 are provided on the positioning base 2. The four positioning blocks 46 and four support blocks 47 are evenly distributed at intervals.

[0088] ② Place the base 70 on the positioning base 2, so that the slot 48 on the bottom surface of the bottom frame 20 matches the positioning protrusion 45. The positioning protrusion 45 is inserted into the slot 48. At the same time, the four corners of the bottom of the main frame 17 are precisely locked and engaged at the four positioning blocks 46. Meanwhile, the four support diagonal rods 18 on the base 70 are precisely locked and supported in the slots 49 of the four support blocks 47. The positioning protrusion 45 is inserted into the slot 48 of the bottom frame 20, realizing the locking and limiting of the base 70 and the positioning base 2. The positioning blocks 46 limit and lock the four corners of the main frame 17, further improving the stability of the base 70 on the positioning base 2. At the same time, the support blocks 47 provide auxiliary support for the support diagonal rods 18, making the base 70 more firmly placed on the positioning base 2, making it easier to lift and lower the base 70 later, and improving the safety of operation.

[0089] ③ Two inner limit blocks 53 are diagonally arranged on the positioning protrusion 45. Two movable adjustment grooves 54 are provided on the positioning protrusion 45. The inner limit blocks 53 slide and limit within the corresponding movable adjustment grooves 54. The inner limit blocks 53 move along the movable adjustment grooves 54, so that the inner limit blocks 53 gradually move and engage with the corresponding side rib rod 21. Then, the inner limit blocks 53 are fixed with the positioning block 46 provided at the side rib rod 21. The positioning block 46 is provided with a positioning post 50, and the inner limit blocks 53 is provided with an opening groove 51. When the inner limit blocks 53 move along the movable adjustment grooves 54 and engage with the side rib rod 21, the positioning post 50 also engages with the opening groove 51. After the inner limit blocks 53 and the side rib rod 21 are engaged, the clamping nut 52 is screwed into the top of the positioning post 50 and tightened. The two inner limit blocks 53 are arranged symmetrically. This design ensures that the two inner limit blocks 53 can be precisely locked onto the two diagonally positioned side ribs 21 on the main frame 17, further locking and limiting them from inside the bottom frame 20. This also secures the inner limit blocks 53 to the corresponding positioning blocks 46, effectively ensuring the stability and reliability of the bottom frame 20 on the positioning base 2. This prevents the bottom frame 20 from shaking or tilting during the lifting operation of the lifting column 6, improving operational safety. When installing the inner limit blocks 53 and positioning blocks 46, as the inner limit blocks 53 move and lock onto the corresponding side ribs 21, they gradually lock onto the positioning post 50 on the corresponding positioning block 46 through the opening slot 51. Then, the clamping nut 52 is used for tightening and fixing, ensuring the secure installation between the inner limit blocks 53 and positioning blocks 46. The design is reasonable, and installation and disassembly are convenient and simple.

[0090] The movable adjustment groove 54 includes a vertically penetrating movable groove section 1 55 and a movable groove section 2 56. A dovetail slider 57 is provided at the bottom of the inner limiting block 53. The movable groove section 2 56 matches the dovetail slider 57. When the inner limiting block 53 slides within the movable groove section 2 56, the dovetail slider 57 slides and engages with it. A locking groove 59 is provided on the dovetail slider 57. A locking protrusion 58 is provided within the movable groove section 1 55, and the locking protrusion 58 matches the locking groove 59. When the inner limiting block 53 slides within the movable groove section 1 55, the dovetail slider... 57 slides and engages within the first moving groove 55, while the dovetail slider 57 slides and engages with the inserting protrusion 58 via the inserting groove 59; the structure is cleverly and reasonably designed. The design of the dovetail slider 57 can ensure that the inner limiting block 53 slides and is limited within the second moving groove 56, preventing the inner limiting block 53 from disengaging from the second moving groove 56. The clever design of the inserting protrusion 58 and the inserting groove 59 ensures that the inner limiting block 53 is always restricted by the inserting protrusion 58 when sliding within the first moving groove 55, preventing the inner limiting block 53 from disengaging from the first moving groove 55.

[0091] (3) The lifting column 6 is started, and the lifting column 6 pushes the lifting support platform 7 to move upward. The lifting support platform 7 drives the positioning base 2 to move upward synchronously, thereby driving the base 70 installed on the positioning base 2 to move upward synchronously until the top surface of the base 70 touches the roof fixed structure layer 26; the lifting operation is automated. The lifting column 6 lifts to adjust the height of the base 70, so that the base 70, which is precisely positioned with the positioning point, moves to the roof fixed structure layer 26, and achieves precise positioning of the base 70 on the roof fixed structure layer 26;

[0092] (4) The top surface of the top frame 22 is provided with an expanded panel 27, and the top end of the supporting diagonal rod 18 is provided with an extension plate 28. The top surface of the extension plate 28 is flush with the top surface of the expanded panel 27. Both the expanded panel 27 and the extension plate 28 have pre-set mounting holes 29. Mark the drilling positions on the roof fixed structure layer 26 from the corresponding mounting holes 29. Start the lifting column 6. The lifting column 6 drives the base 70 to descend a certain height, leaving space for drilling operations above. Then, drill holes at the drilling positions according to the size of the expansion bolts 30, install the embedded parts into the holes, and then start the lifting column 6 to move the base 70 upward until the top surface of the base 70 touches the roof fixed structure layer 26. Screw in the expansion bolts 30 to fix the base 70 and the roof fixed structure layer 26. When the base 70 is installed and positioned on the roof fixed structure layer 26, the expanded panel 27, The extension plates 28 are all attached to the roof fixed structure layer 26, and the expansion plate 27 and the extension plates 28 are all pre-set with mounting holes 29. The base 70 and the roof fixed structure layer 26 need to be fixed at the mounting holes 29 by expansion bolts 30. The drilling position is located by the mounting holes 29 on the base 70, which effectively ensures the drilling accuracy and makes it easier to install and fix the base 70 and the roof fixed structure layer 26. After the drilling position is determined, the base 70 is lowered to a certain height to leave space for drilling operation above. After drilling is completed, the base 70 is moved up again, and the base 70 is installed and fixed to the roof fixed structure layer 26 with the expansion bolts 30. The design is ingenious and reasonable, and the construction is convenient and reasonable. The drilling position is determined by the pre-set mounting holes 29 on the workpiece, which improves the drilling accuracy and makes the actual installation operation easier.

[0093] (5) After the installation and fixing of a base 70 is completed, the base 70 is loosened from the positioning base 2, and then the lifting column 6 is started. The lifting column 6 descends and drives the positioning base 2 to move down synchronously through the lifting support platform 7 until the lifting column 6 descends to the limit position, so that the positioning base 2 is completely separated from the base 70. After the base 70 is loosened from the positioning base 2, the lifting column 6 drives the positioning base 2 to completely separate from the base 70, thus completing the installation of a base 70. The design is reasonable and the construction is convenient and simple.

[0094] The steps for loosening the base 70 and the positioning base 2 are as follows: unscrew the clamping nut 52, and then move the two inner limit blocks 53 towards the center of the positioning protrusion 45 along the moving adjustment groove 54, so that the inner limit blocks 53 are completely disengaged from the corresponding side rib rod 21, and the inner limit blocks 53 are completely moved above the positioning protrusion 45. After the base 70 and the roof fixed structure layer 26 are installed, the inner limit blocks 53 need to be disengaged from the base 70, and the clamping nut 52 needs to be removed to facilitate the movement adjustment of the inner limit blocks 53, so that the movement of the inner limit blocks 53 will not affect the lifting operation of the positioning base 2.

[0095] (6) Adjust the sliding support plate 8 according to the design spacing between the two positioning points, move the sliding support plate 8 along the movable support seat 9, and precisely control the moving distance of the sliding support plate 8 in conjunction with the measuring rod 31 on the side of the sliding support plate 8 and the scale 32 on the movable support seat 9, so that the distance between the measuring rod 31 in the initial state and the measuring rod 31 after the movement is equal to the design spacing between the two positioning points, then lock the sliding support plate 8, and repeat the process from step (1) to step (5) of step 3 to complete the installation and fixing of the next base 70; when a base 70 is completed, there is no need to move and adjust the auxiliary bracket 1. In this section, you only need to adjust the position of the sliding support plate 8 along the movable support base 9 so that the sliding support plate 8 moves to a precise position with another positioning point. The positioning standard is controlled by the moving distance of the measuring rod 31 to ensure that the length distance between the scale 32 before and after the moving of the measuring rod 31 is equal to the distance between the two positioning points. This ensures that the sliding support plate 8 moves into place. Then, lock the sliding support plate 8 to ensure that the sliding support plate 8 cannot move after it moves into place. Then repeat the installation process of the first base 70. The positioning adjustment is convenient and simple, which is more conducive to actual construction operations.

[0096] The locking steps for the sliding support plate 8 include:

[0097] ① Two adjustment frames 60 are symmetrically arranged on the movable support base 9. The top surface of the adjustment frame 60 is provided with a scale 32. The two adjustment frames 60 and the movable support base 9 form an adjustment groove 61. The sliding support plate 8 is slidably engaged in the adjustment groove 61. Two measuring rods 31 are symmetrically arranged on the sliding support plate 8, and the two measuring rods 31 correspond to the two adjustment frames 60. The structure is compact and reasonable. The scale 32 is provided on both adjustment frames 60. With the design of the two measuring rods 31, the scale 32 can be read from both sides, which is more convenient for actual adjustment operation. Moreover, the readings of the scale 32 on both sides can be mutually verified, which improves the accuracy of adjustment operation and avoids adjustment error.

[0098] ② A limiting rod 62 is provided on the sliding support plate 8. The limiting rod 62 is slidably engaged within the adjusting frame 60. A guide rod 63 is also provided at the end of the limiting rod 62, extending outwards from the outside of the adjusting frame 60. A locking nut 64 is provided at the extended end of the guide rod 63. When the sliding support plate 8 moves into position along the adjusting groove 61, the locking nut 64 is tightened to limit and fix the sliding support plate 8 and the movable support seat 9. The sliding support plate 8 slides between the two sides via the limiting rod 62. Within the adjustment frame 60, the horizontality and reliability of the sliding support plate 8 during movement are ensured. At the same time, a guide rod 63 is set on the limiting rod 62, and the guide rod 63 extends out to the corresponding adjustment frame 60. The sliding support plate 8 is limited and fixed on the movable support seat 9 by the guide rod 63 and the locking nut 64. When it is necessary to move the sliding support plate 8, the locking nut 64 is loosened. When the sliding support plate 8 is moved into place, the locking nut 64 is tightened. The structure is ingenious and reasonable, and is convenient and simple to use and adjust.

[0099] 4. Installation of the crane tower:

[0100] (1) The gantry includes a crossbeam 33 and a functional component 34. The functional component 34 is slidably engaged on the sliding track of the crossbeam 33. The top of the crossbeam 33 is provided with a connecting plate 35 corresponding to the two bases 70. The ceiling 72 is provided with a hole for the connecting plate 35 to pass through, so that the connecting plate 35 is just hidden between the ceiling 72 and the roof structure fixed layer 26.

[0101] (2) Loosen the binding rope and move the mounting plate 24 downwards until it abuts against the limit position inside the bottom frame 20. Weld the mounting plate 24 to the bottom frame 20 and fix it in place. The positioning screw 25 on the mounting plate 24 should extend and protrude from the outside of the bottom frame 20. First, screw two clamping nuts 36 into the positioning screw 25. Adjust the position of the uppermost clamping nut 36 so that it rotates and abuts against the bottom surface of the mounting plate 20. Then weld the clamping nut 36 to the mounting plate 20 and fix it in place. The structure is cleverly designed. If the mounting plate 24 is fixed inside the bottom frame 20 first, it will affect the installation between the base 70 and the positioning base 2. For positioning, the mounting plate 24 is initially fixed to the base 70 by binding ropes. After the base 70 is installed, the binding ropes are loosened, and the mounting plate 24 is pressed and limited within the bottom frame 20. Then, the mounting plate 24 and the bottom frame 20 are welded together to ensure the installation is firm. At the same time, a clamping nut 36 is set at the connection end between the positioning screw 25 and the mounting plate 24. The clamping nut 36 is threaded to the positioning screw 25, and the clamping nut 36 is welded to the mounting plate 24 to improve the structural firmness and strength at the connection end between the positioning screw 25 and the mounting plate 24, resulting in better overall load-bearing capacity.

[0102] (3) Install the crossbeam 33, align the two connecting plates 35 on the crossbeam 33 with the two bases 70. The connecting plates 35 are provided with connecting holes. The end of the positioning screw 25 extends through the corresponding connecting hole. Then screw a clamping nut 36 into the positioning screw 25. Adjust the position of the two lowest clamping nuts 36 on the positioning screw 25. The two lowest clamping nuts 36 limit and fix the connection plate 35 and the positioning screw 25, thereby realizing the installation and fixation between the crossbeam 33 and the base 70. When installing the crossbeam 33 and the base 70, align the connecting plate 35 with the base 70, insert the positioning screw 25 into the corresponding connecting hole on the connecting plate 35, and then use the two clamping nuts 36 to limit and fix the connecting plate 35 on the positioning screw 25, thereby realizing the installation and fixation between the crossbeam 33 and the base 70. The design is reasonable, and the installation and disassembly are convenient and simple, which is convenient for subsequent inspection and maintenance.

[0103] (4) Slide the functional component 34 from both ends of the crossbeam 33 onto the sliding guide rail. The crossbeam 33 has corresponding end caps at both ends. When installing the functional component 34, remove the end caps from the crossbeam 33, slide the functional component 34 onto the sliding guide rail of the crossbeam 33, and stop the functional component 34 in a reasonable position. After completing the assembly between the functional component 34 and the crossbeam 33, install the end caps back onto the crossbeam 33.

[0104] The present invention features a clever and reasonable structural design. It maps the positioning points on the roof to auxiliary points on the ground, and with the design of the auxiliary support 1, the positioning of the base 70 is directly adjusted based on these auxiliary points on the ground. The positioning adjustment process is performed directly below ground, eliminating the need for high-altitude positioning adjustments, making the overall construction more convenient and simple. It also ensures precise positioning between the base 70 and the positioning points after adjustment, thus guaranteeing the actual construction quality. Furthermore, the base 70 is fixed to the roof fixed structure layer 26 using expansion bolts 30, ensuring both the actual installation's firmness and facilitating the installation and disassembly of the base 70. The installation position of the expansion bolts 30 on the roof fixed structure layer 26 is precisely assisted by the pre-set mounting holes 29 on the base 70, thereby improving positional accuracy and making the installation of the base 70 more secure and reliable.
