Description

Technical Field

[0001] This application relates to the field of large equipment installation technology, specifically to a method for positioning large equipment within a confined space and multi-layered frame. Background Technology

[0002] In multi-story frame factory buildings and other similar settings, the installation of large equipment often faces space constraints. Due to the large size and weight of the equipment, and the dense distribution of beams and columns within the multi-story frame, the hoisting and transportation of the equipment is easily restricted by space obstructions, making it difficult to accurately reach the preset placement point. Furthermore, traditional installation methods lack transfer and sliding mechanisms adapted to narrow spaces, resulting in low efficiency in positioning multiple pieces of equipment in an orderly manner along the axis, which cannot meet the needs of rapid and accurate installation of large equipment. Summary of the Invention

[0003] To solve, or at least partially solve, the above-mentioned technical problems, this application provides a method for positioning large equipment within a confined space and multi-layered frame.

[0004] This application provides a method for positioning large equipment within a confined space and multi-layered frame, including:

[0005] S1. Modularly disassemble large equipment into multiple equipment modules according to the structural characteristics of the large equipment, so that the equipment modules can adapt to the needs of transportation and hoisting in narrow spaces.

[0006] S2. Construct a high-altitude steel structure receiving platform at a predetermined elevation position of the multi-layer frame, and lay tracks and configure sliding trolleys on the high-altitude steel structure receiving platform.

[0007] S3. In a preset order, each of the equipment modules is hoisted one by one into the sliding trolley of the high-altitude steel structure receiving platform by hoisting equipment to complete the high-altitude transfer.

[0008] S4. Slide the sliding trolley carrying the equipment module along the track to directly below the hoist assembly of the single beam crane of the frame, and simultaneously pull the equipment module through the hoist assembly to move it to the preset placement point;

[0009] S5. Assemble and weld the equipment module at the preset placement point to complete the installation of a single device.

[0010] S6. Proceed in segments along the axis of the multi-layer frame, repeating S3 to S5 until all large equipment is slid into place.

[0011] Alternatively, modular splitting can be performed in the following manner:

[0012] Based on the beam and column distribution of the multi-layer frame and the sliding path of the high-altitude steel structure receiving platform, the large equipment is divided into multiple equipment modules. The center of gravity of each equipment module corresponds to the bearing center of the sliding trolley. The external dimensions of the equipment modules can avoid the obstruction of the beams and columns of the multi-layer frame, and the assembly and mating positions of the equipment modules avoid the support structure of the high-altitude steel structure receiving platform.

[0013] Optionally, the track is provided with positioning components corresponding one-to-one with each of the preset positioning points, the bottom of the sliding trolley is provided with positioning mating components adapted to the positioning components, and the sides of the sliding trolley are provided with guide structures extending along the track; the sliding positioning of the sliding trolley in S4 includes the following steps:

[0014] When the sliding trolley carrying the equipment module slides along the track, the guide structure restricts the offset direction of the sliding trolley. When the sliding trolley slides to a preset position, the positioning mating part is aligned with the corresponding positioning part for calibration, thereby aligning the equipment module with the traction point of the hoist assembly.

[0015] Optionally, the positioning component has a tapered guide opening along the track extension direction, the positioning mating component has a tapered guide head adapted to the tapered guide opening, and the positioning component has an elastic positioning pin that can extend and retract along the vertical direction of the track. The positioning mating component has a positioning hole at a corresponding position. The sliding positioning of the sliding trolley in step S4 further includes the following steps:

[0016] When the conical guide head enters the conical guide opening, the sliding trolley is initially positioned by the cooperation between the conical guide opening and the conical guide head. The sliding trolley is then pushed until the elastic positioning pin is elastically engaged in the positioning hole, thus completing the alignment of the equipment module with the hoist assembly traction point.

[0017] Optionally, the hoist assembly includes two opposing traction hoists, and the equipment module is equipped with a level detection element; the step in S4 of synchronously tractioning the equipment module through the hoist assembly includes:

[0018] When the two traction hoists are pulling, the horizontal status information of the equipment module is obtained in real time through the horizontal detection device;

[0019] Adjust the traction speed of the corresponding traction hoist according to the horizontal state information, so that the equipment module is kept horizontal and moved to the preset position.

[0020] Optionally, the device module is further provided with a lateral positioning detection component, and a lateral reference mark adapted to the lateral positioning detection component is provided next to the track; the step of synchronously pulling the device module through the hoist assembly in S4 further includes:

[0021] Before traction, the initial horizontal state of the equipment module is calibrated by the horizontal detection component, and the initial lateral position of the equipment module relative to the track is calibrated by the lateral positioning detection component.

[0022] During the traction process, the lateral offset information of the equipment module relative to the lateral reference mark is obtained in real time through the lateral positioning detection component; combined with the horizontal state information and the lateral offset information, the traction speed and traction stroke of the two traction hoists are adjusted to maintain the horizontal state of the equipment module and correct the lateral offset of the equipment module, so that the equipment module is translated along the preset path to the preset placement point.

[0023] Optionally, the bottom of the high-altitude steel structure receiving platform is provided with a translation guide that can extend laterally along the multi-layer frame. The multi-layer frame is provided with tooling positioning references that correspond one-to-one with each axis. The high-altitude steel structure receiving platform is also provided with a quick-locking component adapted to the tooling positioning references. The tooling reuse step in S6, which proceeds in segments according to the axis, includes:

[0024] After the installation of all the equipment modules on the current axis is completed, the quick-locking parts are unlocked to allow the high-altitude steel structure receiving platform to be released from the positioning constraints of the current axis.

[0025] The high-altitude steel structure receiving platform, the track, and the sliding trolley are moved as a whole to the position corresponding to the next axis along the translation guide.

[0026] The position of the high-altitude steel structure receiving platform is calibrated by the tooling positioning reference, so that the track is aligned with the preset placement point of the next axis, and then the high-altitude steel structure receiving platform is fixed by the quick locking component.

[0027] After fixing, repeat steps S3 to S5 to position the next large piece of equipment on the axis.

[0028] Optionally, an inherent reference mark is provided next to the preset placement point of the multi-layer frame, and the device module is provided with an alignment detection structure adapted to the inherent reference mark; the step S5, before assembling the device module, further includes the following steps:

[0029] After placing the upper and lower sections of the device module at the preset docking positions, the positional deviation of the device module relative to the inherent reference mark is read through the alignment detection structure.

[0030] The height and horizontal position of the lower section of the equipment module are finely adjusted according to the positional deviation, so that the assembly joints of the upper and lower sections of the equipment module are aligned along the preset docking trajectory, and then welded and fixed.

[0031] Optionally, the inherent beam and column surfaces of the multi-layer frame are provided with a hoisting attitude calibration reference; the step of hoisting the equipment module to the sliding trolley in S3 includes:

[0032] When the equipment module is lifted by hoisting equipment and moved above the high-altitude steel structure receiving platform, the force distribution of the lifting points of the equipment module is adjusted with reference to the hoisting posture calibration benchmark, and the horizontal posture and placement angle of the equipment module are calibrated.

[0033] After the device module's orientation is adapted to the bearing surface of the sliding trolley, the device module is placed inside the sliding trolley so that the device module and the bearing surface of the sliding trolley are fully in contact.

[0034] Optionally, before the sliding trolley slides along the track in step S4, the following steps are also included:

[0035] Using the inherent beams and columns of the multi-layer frame as a reference, mark the safe sliding path of the sliding trolley and determine the minimum safe distance between the equipment module and each beam and column;

[0036] During the sliding process, the relative position of the equipment module and the inherent beam and column is obtained, and the sliding direction of the sliding trolley is adjusted in combination with the marking of the safe sliding path and the minimum safe distance.

[0037] The method provided in this application has the following beneficial effects:

[0038] The method provided in this application addresses the challenge of positioning large equipment within confined spaces and multi-story frames. By modularizing the large equipment, it breaks it down into modules adapted to the needs of transfer and hoisting in confined spaces, effectively solving the problem of large equipment being unable to enter confined spaces as a whole and making hoisting difficult. A high-altitude steel structure receiving platform is constructed at a predetermined elevation within the multi-story frame, equipped with tracks and sliding trolleys. This provides a stable high-altitude transfer hub and horizontal transfer path for the equipment modules, replacing the traditional method of direct operation using crane booms and avoiding blind spots created by the beams and columns of the multi-story frame.

[0039] The equipment modules are hoisted into a sliding trolley using a lifting device in a preset sequence for high-altitude transfer. They then slide along a track directly beneath the hoist assembly of a single-beam crane, where the hoist assembly simultaneously pulls them to their preset placement points. The cooperation between the track and the hoist assembly allows the equipment modules to move accurately within the confined space at high altitudes, avoiding collisions with the frame structure. The equipment modules at their preset placement points are then assembled, welded, and secured, ensuring stable installation of a single unit. Subsequent installations can be completed by repeating the core steps, progressing segment by segment along the multi-layered frame axis, to place multiple units of equipment.

[0040] This operating method eliminates the need to repeatedly set up core tooling for each piece of equipment. It ensures the installation stability of a single piece of equipment through modular disassembly and accurate transportation, while improving the efficiency of batch placement of multiple pieces of equipment through progressive operation. It is effectively adapted to special operating environments with narrow spaces and multi-layered frames. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0046] See Figures 1 to 2 This application provides a method for positioning large equipment within a confined space and multi-layered frame, including:

[0047] S1. Modularize large equipment by dividing it into multiple equipment modules according to its structural characteristics, so that the equipment modules can adapt to the needs of transportation and hoisting in narrow spaces.

[0048] S2. Construct a high-altitude steel structure receiving platform at the preset elevation position of the multi-layer frame, lay tracks on the high-altitude steel structure receiving platform and configure sliding trolleys.

[0049] S3. In the preset order, each equipment module is hoisted one by one into the sliding trolley of the high-altitude steel structure receiving platform by hoisting equipment to complete the high-altitude transfer;

[0050] S4. Slide the trolley carrying the equipment module along the track to the hoist assembly of the single beam crane of the frame, and use the hoist assembly to synchronously pull the equipment module to move it to the preset position.

[0051] S5. Assemble and weld the equipment modules at the preset placement points to complete the installation of a single device.

[0052] S6. Proceed in segments along the axis of the multi-layer frame, repeating S3 to S5 until all large equipment is slid into place.

[0053] Figure 2 This is a schematic diagram illustrating a scenario where a large piece of equipment is positioned within a confined space and a multi-layered frame, as provided in an embodiment of this application. Figure 2 The diagram simply illustrates equipment module 11, the high-altitude steel structure receiving platform 12, the sliding trolley 13, and the hoist assembly 14 to help understand the application scenario. A multi-layered frame in a confined space typically refers to a multi-layered steel or concrete frame composed of beams and columns within an industrial plant. These frames are often surrounded by existing equipment, pipelines, or walls, significantly limiting the operational space for equipment entry, exit, and installation. Large equipment refers to industrial equipment that is large in size and weight, making it impossible to directly access or hoist it to a designated location within a multi-layered frame, such as heavy-duty reactors and large heat exchangers. Equipment modules are independent components formed by disassembling large equipment according to certain rules; their size and weight are adapted for subsequent transfer and hoisting operations.

[0054] In such scenarios, the overall placement of large equipment often faces numerous difficulties. Either it cannot pass through narrow gaps between frames, or the boom of the hoisting equipment struggles to operate accurately in multi-layered structures. Therefore, modular disassembly of the large equipment is the first step. This disassembly must consider the equipment's structural characteristics, such as the distribution of welds, load-bearing components, and ease of subsequent assembly. The goal is to ensure that the disassembled modules do not compromise the original structural stability of the equipment, can accommodate passage through confined spaces, and simultaneously meet the load-bearing capacity of the hoisting equipment.

[0055] After disassembly, a high-altitude steel structure receiving platform needs to be erected at a predetermined elevation on the multi-layered frame. This platform is typically constructed from welded steel sections and fixed to the beams and columns of the frame via connectors to ensure sufficient load-bearing strength and stability. Its erection height must match the installation height of the equipment modules, providing a stable high-altitude receiving and transfer carrier. On the top surface of the high-altitude steel structure receiving platform, tracks are laid along the predetermined transfer direction of the equipment modules. The track's length covers the operating range from that of the hoisting equipment to that of a single-beam crane. Sliding trolleys are mounted on the tracks, allowing for horizontal transfer of the equipment modules at high altitudes.

[0056] Next, following a pre-set sequence, each equipment module is hoisted one by one into the sliding trolley of the high-altitude steel structure receiving platform using hoisting equipment, completing the high-altitude transfer. Hoisting equipment can be either a truck crane or a tower crane. The pre-set sequence is usually determined by the installation order of the equipment modules; generally, the modules corresponding to the lower-level equipment are hoisted first, followed by the upper-level modules, to avoid interference with the already positioned modules during subsequent hoisting operations. During the hoisting process, the attitude of the hoisting equipment needs to be adjusted to ensure the equipment modules are smoothly moved above the high-altitude steel structure receiving platform and slowly lowered into the sliding trolley, ensuring the equipment modules are placed stably.

[0057] The sliding trolley carrying the equipment module is then moved along the track to directly beneath the hoist assembly of the single-girder crane on the frame. The single-girder crane is a lifting device installed on the top surface or floor beams of a multi-story frame. Its hoist assembly consists of a hook, wire rope, and traction device, enabling vertical lifting and horizontal traction of the equipment module. Once the sliding trolley reaches the designated position, the hook of the hoist assembly is securely connected to the lifting point on the equipment module. The hoist assembly then synchronously pulls the equipment module, moving it horizontally to the preset installation point. This preset installation point is a pre-marked installation reference position on the multi-story frame, which must correspond to the designed installation position of the equipment.

[0058] At the pre-set installation points, the equipment modules are assembled, joined, and welded together to complete the installation of a single unit. During assembly, the positions of the equipment modules need to be adjusted to align the connection points of each module and meet the structural requirements of the equipment. After that, they are welded together to connect all the equipment modules into a whole, restoring the original structural performance of the equipment.

[0059] Finally, following the axis of the multi-layered frame, the process is repeated segment by segment, involving hoisting the equipment modules onto the sliding trolley, sliding them, pulling them to their designated positions, and assembling and welding them, until all large pieces of equipment are slid into place. The axis is the basic layout reference for the multi-layered frame. Segmenting by axis means that each frame area corresponding to an axis is considered a work unit. After completing the installation of equipment in one unit, work is then carried out on adjacent units. This method ensures that the entire installation process proceeds in an orderly manner and avoids interference between work in different areas.

[0060] This method of positioning large equipment effectively solves the problem of installing large equipment in confined spaces and multi-layered frames. Modular disassembly allows the equipment to adapt to limited operating spaces. The combination of a high-altitude steel structure receiving platform and a sliding trolley provides a stable high-altitude transport path for the equipment modules, avoiding the problem of obstructed operation of hoisting equipment in multi-layered structures. The axially progressive operation method improves the overall efficiency of installing multiple pieces of equipment, fully adapting to the special operating environment of confined spaces and multi-layered frames.

[0061] The construction of high-altitude steel structure material receiving platforms can adopt a modular splicing approach, reducing on-site welding work and adapting to operations in confined spaces. The main body of the platform is composed of prefabricated steel frame units, which are connected by bolts, eliminating the need for large-scale on-site welding. During construction, pre-embedded connectors are first fixed to the frame beams and columns, and then the prefabricated units are hoisted and connected one by one. The position of the units is finely adjusted by adjusting the elongated holes on the connectors to ensure the flatness of the top surface of the high-altitude steel structure material receiving platform. To address the height differences of the multi-layered frame, the platform support legs adopt a telescopic structure, and the length is adjusted by screws to ensure that the top surface of the platform accurately reaches the preset elevation. This construction method does not require large welding equipment that occupies space, has a fast splicing speed, can quickly form a stable receiving carrier, and is easy to disassemble and reuse later.

[0062] In some implementations, modular decomposition is performed in the following manner:

[0063] Based on the beam and column distribution of the multi-layer frame and the sliding path of the high-altitude steel structure receiving platform, the large equipment is divided into multiple equipment modules. The center of gravity of each equipment module corresponds to the load-bearing center of the sliding trolley. The external dimensions of the equipment modules can avoid the obstruction of the beams and columns of the multi-layer frame, and the assembly and mating positions of the equipment modules avoid the support structure of the high-altitude steel structure receiving platform.

[0064] When positioning large equipment within a confined, multi-layered frame, the rationality of modular disassembly affects the efficiency of subsequent transportation, hoisting, and assembly. Therefore, disassembly must be based on the structural characteristics of the large equipment itself, and further considered in relation to the actual layout of the multi-layered frame and the high-altitude steel structure receiving platform. The distribution of beams and columns in the multi-layered frame is the primary external constraint to consider during disassembly. As the core supporting structure of the frame, the beams and columns are fixed in position and protrude from the internal space of the frame. Before disassembly, the arrangement position, cross-sectional shape, and extension direction of each beam and column can be clearly defined, so that the dimensions of the disassembled equipment modules can avoid obstruction by the beams and columns during transportation, preventing collisions or jamming between modules and beams and columns.

[0065] The sliding path of the high-altitude steel structure receiving platform is determined by the direction of the track laying, which limits the horizontal movement trajectory of the equipment modules at high altitudes. During disassembly, this path must be used as a reference to control the length and width of the equipment modules, ensuring they can be stably placed on the sliding trolley and slide smoothly along the track. Simultaneously, the placement direction of the equipment modules must be consistent with the sliding path to avoid safety issues caused by modules protruding from the track. The load-bearing center of the sliding trolley is the key area for stable support of the modules, typically the geometric center of the trolley's load-bearing surface. During disassembly, structural analysis is needed to determine the center of gravity of each equipment module, ensuring it corresponds to the load-bearing center of the sliding trolley. This ensures that the weight of the equipment modules is evenly distributed to the trolley during movement, preventing tilting of the modules or jamming of the trolley due to a shift in the center of gravity.

[0066] The assembly joints of large equipment are the connection points for subsequent modules, typically located on the end faces of the equipment modules or pre-installed flange structures. During disassembly, these joint locations must be staggered from the supporting structure of the aerial steel structure receiving platform. The supporting structure of the aerial steel structure receiving platform includes diagonal braces connecting the frame beams and columns, uprights, and the bottom load-bearing beams. These structures occupy considerable operating space. If the joint locations overlap with the supporting structure, tools and personnel will have difficulty accessing them during subsequent assembly and welding, affecting connection quality and efficiency. Therefore, during disassembly, the layout range of the platform's supporting structure must first be marked, and then the joint locations must be planned based on the structural characteristics of the equipment, ensuring that the joints are located in the gaps between the supporting structures, leaving sufficient space for subsequent operations.

[0067] After being split in this way, the equipment modules can not only adapt to the passage requirements of narrow spaces and the load-bearing requirements of sliding trolleys, but also avoid the obstruction of multi-layer frame beams and columns and platform support structures, so that subsequent hoisting, sliding and assembly operations can be carried out smoothly. This not only ensures the safety of each operation, but also provides a guarantee for the final installation quality of the equipment.

[0068] In some embodiments, the track is provided with positioning components that correspond one-to-one with each preset positioning point, the bottom of the sliding trolley is provided with positioning fitting components that are adapted to the positioning components, and the sides of the sliding trolley are provided with guide structures along the extension direction of the track; the sliding positioning of the sliding trolley in S4 includes the following steps:

[0069] When the sliding trolley carrying the equipment module slides along the track, the guide structure restricts the offset direction of the sliding trolley. When the sliding trolley slides to the preset position, the positioning mating parts are aligned with the corresponding positioning parts for calibration, thereby aligning the equipment module with the traction point of the hoist assembly.

[0070] Within a confined, multi-layered frame, after the equipment module slides along the track via a trolley, it must align with the traction point of the hoist assembly of the single-beam crane. Otherwise, the hoist assembly hook may fail to connect smoothly, or the equipment module may shift and collide with the frame structure during traction. Therefore, it is necessary to consider setting appropriate positioning structures on the track and trolley, along with guiding devices to ensure sliding stability.

[0071] The positioning components on the track correspond one-to-one with each preset positioning point. Before installation, the fixed positions of the positioning components are marked on the track according to the preset positioning points. The positioning components can be welded from steel plates, and the bottom is fastened to the track with bolts to ensure that they do not shift under load. Their structure must form a stable connection with the positioning mating components at the bottom of the sliding trolley. The positioning mating components at the bottom of the sliding trolley are designed according to the shape of the positioning components. If the positioning component is a raised positioning block, the positioning mating component is a matching positioning groove; if the positioning component is a positioning pin, the positioning mating component is a positioning hole, ensuring that the two can form a positioning constraint after contact.

[0072] The guide structures on both sides of the sliding trolley are used to prevent slippage and deviation, and are usually in the form of guide wheels or guide plates. The guide wheels are fixed to both sides of the trolley by brackets, and the wheel surface fits tightly against the side of the track, which can reduce the friction when the trolley slips and limit the trolley from deviating to the sides. If guide plates are used, they are directly welded to the side of the trolley, forming a fit with the side of the track with minimal gap, which can also play a stabilizing guiding role, so that the trolley always slides along the extension direction of the track.

[0073] During the sliding positioning process of S4, when the sliding trolley carrying the equipment module is pushed along the track, the guide structures on both sides first come into play. Through the rolling cooperation between the guide wheels and the side of the track, or the limiting effect of the guide plate and the side of the track, the trolley is prevented from lateral swaying due to slight shifts in the center of gravity of the equipment module, ensuring stable sliding direction. As the sliding trolley gradually approaches the preset position, the operator can make a judgment through visual observation or with the aid of a simple ruler. After the sliding trolley has slid to the preset position range, the trolley is continued to be pushed slowly, so that the positioning mating parts at the bottom gradually align with the corresponding positioning parts on the track. As the two are fully engaged, the positioning mating parts and the positioning parts form a mechanical constraint, restricting further movement of the trolley, thereby aligning the lifting point of the equipment module with the traction point of the hoist assembly. This provides a benchmark for the subsequent hook connection and traction operation of the hoist assembly, avoiding repeated adjustments that waste time and reducing the risk of operation in confined spaces.

[0074] In some embodiments, the positioning member has a tapered guide opening along the track extension direction, the positioning mating member has a tapered guide head adapted to the tapered guide opening, and the positioning member has an elastic positioning pin that can extend and retract along the vertical direction of the track. The positioning mating member has a positioning hole at the corresponding position; the sliding positioning of the sliding trolley in S4 also includes the following steps:

[0075] Once the conical guide head enters the conical guide opening, the sliding trolley is initially positioned by the cooperation between the conical guide opening and the conical guide head. The sliding trolley is then pushed until the elastic positioning pin is elastically engaged in the positioning hole, thus completing the alignment of the equipment module and the hoist assembly traction point.

[0076] To further improve the alignment accuracy of the equipment module and the hoist assembly's traction point and reduce adjustments in confined spaces, guiding and locking structures are added to the positioning component and the positioning mating component. The positioning component has a tapered guide opening along the track's extension direction. The outer diameter of this guide opening is larger than the inner diameter, forming a trumpet-shaped guide channel. The inner diameter matches the shape of the tapered guide head of the positioning mating component. The tapered guide head is a tapered protrusion extending outward from the bottom of the sliding trolley, and its taper matches the tapered guide opening. An installation hole is formed inside the positioning component perpendicular to the track. An elastic positioning pin is fitted into this installation hole. A spring is installed at the bottom of the installation hole, with one end fixed to the bottom of the installation hole and the other end connected to the elastic positioning pin. This allows the elastic positioning pin to partially extend beyond the surface of the positioning component under normal conditions and retract inward along the installation hole when subjected to external pressure. A positioning hole is formed on the positioning mating component corresponding to the position of the elastic positioning pin. The diameter of the positioning hole matches the diameter of the extended end of the elastic positioning pin, ensuring a tight fit between the two.

[0077] During the sliding positioning process of S4, when the sliding trolley approaches the preset position under the action of the guide structure, the conical guide head first enters the outer end of the conical guide opening. Due to the trumpet-shaped structure of the conical guide opening, even if the sliding trolley has a slight lateral deviation, the conical surface of the conical guide head will contact the inner wall of the conical guide opening. Through the guiding action of the inclined surface, the sliding trolley is guided to adjust its sliding direction, gradually correcting the deviation and achieving initial positioning. The sliding trolley continues to be slowly pushed, and the conical guide head continues to penetrate deeper along the inner wall of the conical guide opening until the conical surfaces of the two are completely in contact. At this point, the lateral deviation of the sliding trolley has been corrected, and the lifting point of the equipment module is roughly aligned with the traction point of the hoist assembly. As the sliding trolley moves further, the conical guide head will squeeze the protruding end of the elastic positioning pin, causing the elastic positioning pin to retract inward against the spring force. When the sliding trolley moves to the accurate position, the positioning hole on the positioning mating part is exactly aligned with the protruding end of the elastic positioning pin. After the spring loses pressure, it resets, pushing the elastic positioning pin to elastically engage in the positioning hole, forming a rigid locking constraint and restricting the movement of the sliding trolley. This process eliminates the need for additional calibration, enabling alignment between the equipment module and the hoist assembly traction point. This simplifies the workflow in confined spaces, avoids safety hazards caused by repeated adjustments, and improves the efficiency and accuracy of positioning operations.

[0078] In some embodiments, the hoist assembly includes two opposing traction hoists, and the equipment module is equipped with a level detection element; the step S4 of synchronously tractioning the equipment module through the hoist assembly includes:

[0079] When two traction hoists are pulling, the horizontal status information of the equipment module is obtained in real time through the horizontal detection device;

[0080] Adjust the traction speed of the corresponding traction hoist according to the horizontal status information, so that the equipment module can be moved horizontally to the preset position.

[0081] Within a confined, multi-layered frame, relying solely on a single traction structure when pulling equipment modules using a hoist assembly can easily lead to module tilting. This not only affects positioning accuracy but may also cause collisions with the frame structure. Therefore, a hoist assembly consisting of two opposing traction hoists is used to improve traction stability. Electric hoists are selected for their adjustable traction speed and stable traction force. The two traction hoists are fixed to the crossbeam of the single-beam crane via brackets and are symmetrically distributed on both sides of the equipment module.

[0082] The level detection device installed on the equipment module is used to monitor the module's attitude in real time. Considering the working environment and ease of operation, a bubble level or a small electronic level sensor can be selected.

[0083] During the synchronous traction of the equipment module via the hoist assembly in S4, before starting the two traction hoists, the installation status of the level detection device is checked to ensure it is in normal working condition. Simultaneously, it is confirmed that the hooks of both hoists are securely connected to the lifting points of the equipment module to prevent disengagement during traction. After traction is started, the two traction hoists initially pull at the same speed, causing the equipment module to move initially along the preset direction. During this process, the level detection device acquires the horizontal status information of the equipment module in real time.

[0084] Based on the acquired horizontal status information, the traction speed of the corresponding traction hoist is adjusted. For example, if the horizontal detection device shows that the left side of the equipment module is higher, it means that the traction speed of the left traction hoist is faster than that of the right side. In this case, the speed of the left traction hoist is slowed down, or the speed of the right traction hoist is appropriately increased, so that the equipment module gradually returns to horizontal. If the right side is higher, the opposite operation is performed. Through continuous status monitoring and speed adjustment, the equipment module remains horizontal throughout the entire traction process, smoothly moving to the preset positioning point. This effectively avoids structural collisions or positioning deviations caused by module tilting, improving the safety and accuracy of traction operations in confined spaces.

[0085] The reinforcement and adaptation of a single-girder crane requires structural optimization based on the weight of the equipment modules. If the original single-girder crane's load-bearing capacity is insufficient, a reinforcement beam can be added below its crossbeam. This reinforcement beam, made of I-beams, is fixed to the crane body at both ends with clamps, forming a combined load-bearing structure with the crossbeam to improve overall load-bearing strength. The hoist assembly is replaced with a large-tonnage hook and high-strength steel wire rope to ensure stable connection with the lifting points of the equipment modules. Furthermore, limit blocks can be added to both ends of the single-girder crane's track to prevent the hoist assembly from exceeding its travel range during traction. The reinforced single-girder crane can adapt to the weight requirements of the equipment modules, while the limit structure improves operational safety, preventing accidents caused by equipment loss of control in confined spaces.

[0086] In some embodiments, the equipment module is further provided with a lateral positioning detection component, and a lateral reference mark adapted to the lateral positioning detection component is provided next to the track; the step of synchronously pulling the equipment module by the hoist assembly in S4 also includes:

[0087] Before traction, the initial horizontal state of the equipment module is calibrated by the horizontal detection component, and the initial lateral position of the equipment module and the track is calibrated by the lateral positioning detection component.

[0088] During the traction process, the lateral offset information of the equipment module relative to the lateral reference mark is obtained in real time through the lateral positioning detection component; combined with the horizontal status information and the lateral offset information, the traction speed and traction stroke of the two traction hoists are adjusted to maintain the horizontal status of the equipment module and correct the lateral offset of the equipment module, so that the equipment module is moved along the preset path to the preset placement point.

[0089] To further improve the accuracy of traction of equipment modules in confined spaces and avoid the combined problems of lateral offset and horizontal tilt during traction, lateral positioning detection devices can be added to the equipment modules, with corresponding lateral reference marks placed next to the track. The lateral positioning detection devices can be laser positioning sensors or infrared rangefinders, fixed to the side of the equipment module by brackets. Their detection direction is perpendicular to the track extension direction, enabling them to identify the position of the lateral reference marks. The lateral reference marks, using reflective strips or scale plates, are fixed to multi-layered frame beams or supporting structures next to the track, continuously arranged along the track extension direction, ensuring that the lateral positioning detection devices can always capture the mark signals during traction.

[0090] During the synchronous traction of the equipment module via the hoist assembly in S4, a dual initial calibration must be performed before traction. On one hand, the initial level of the equipment module is checked using a leveling detector. If the equipment module is detected to be tilted, the bearing surface of the sliding trolley or the module position can be adjusted to ensure that the leveling detector indicates that the equipment module is level. On the other hand, the lateral positioning detector is aligned with the initial zero point of the lateral reference mark, and the relative lateral position of the equipment module and the track is recorded. If there is an initial offset, the position of the equipment module can be finely adjusted by pushing the sliding trolley to ensure that the initial lateral position of the equipment module is consistent with the preset path.

[0091] After traction is initiated, the two traction hoists pull synchronously at their initial speeds. The lateral positioning detection device captures the signal from the lateral reference mark in real time, continuously acquiring information on the lateral offset of the equipment module relative to the reference mark. If the module shifts to one side of the track, the lateral positioning detection device will report the direction of the shift and the change in relative position. Combining the horizontal status information and lateral offset information from the horizontal detection device, the traction speed and traction stroke of the two traction hoists are adjusted synchronously: for example, if the equipment module is both tilted to the left and shifted laterally to the left, the traction speed of the left traction hoist can be slowed down, while the traction stroke of the right traction hoist can be appropriately increased. This corrects the horizontal tilt through the speed difference and offsets the lateral offset through the stroke difference. If the equipment module is horizontal but has a lateral offset, the traction speed of the two hoists is kept consistent, and the traction stroke of one of them is finely adjusted until the offset is eliminated.

[0092] This adjustment method ensures that the equipment module remains horizontal during traction and moves strictly along the preset path, effectively avoiding the risk of the module colliding with the frame structure due to the superposition of lateral offset and tilt in a narrow space. This further improves the accuracy of the equipment module's translation to the preset positioning point and reduces the amount of adjustment work after positioning.

[0093] In some embodiments, the bottom of the high-altitude steel structure receiving platform is provided with a translation guide that can extend laterally along the multi-layer frame. The multi-layer frame is provided with tooling positioning references that correspond one-to-one with each axis. The high-altitude steel structure receiving platform is also provided with quick-locking components adapted to the tooling positioning references. The tooling reuse step in S6, which proceeds in segments according to the axis, includes:

[0094] After completing the installation of all equipment modules on the current axis, unlock the quick-locking parts to free the high-altitude steel structure receiving platform from the positioning constraints of the current axis;

[0095] The high-altitude steel structure receiving platform, track, and sliding trolley are moved as a whole to the corresponding position on the next axis along the translation guide.

[0096] The position of the high-altitude steel structure receiving platform is calibrated by the tooling positioning reference, so that the track corresponds and aligns with the preset placement point of the next axis, and then the high-altitude steel structure receiving platform is fixed by the quick locking device.

[0097] After fixing, repeat steps S3 to S5 to position the next large piece of equipment on the axis.

[0098] The core of the reusable tooling design for high-altitude steel structure material receiving platforms is to reduce the amount of repetitive erection work through a movable structure, which is especially suitable for the needs of multi-story frames operating in sections along axes. The movable guide components are typically made of heavy-duty channel steel or I-beams, fixed to the crossbeams or load-bearing structure of the multi-story frame along its lateral extension, covering the entire range of the axes to be worked on. The bottom of the high-altitude steel structure material receiving platform is welded with sliders or rollers adapted to the movable guide components. The sliders are embedded in the grooves of the guide components, ensuring that the platform can only move smoothly along the direction of the guide components, without lateral deviation.

[0099] The tooling positioning reference on the multi-layer frame needs to correspond one-to-one with each axis. This is typically achieved using positioning pins or graduated positioning plates. Positioning pins are fixed to the beam-column joints of the frame with bolts, with a set for each axis, their spacing and height matching the positioning holes on the bottom of the receiving platform. If positioning plates are used, the reference lines for each axis can be marked. Quick-locking components enable rapid fixing and unlocking of the receiving platform. These can be manual bolt locking mechanisms or snap-locking devices, installed on the bottom or side of the receiving platform, forming a stable connection constraint with the tooling positioning reference.

[0100] In the S6 segmented, progressive operation along the axis, after completing the installation of all equipment modules on the current axis, the quick-locking mechanism is first used to unlock it. If it's a bolt-type structure, the locking bolts are loosened to release the receiving platform from the locating pins; if it's a snap-lock structure, the unlocking handle is pulled to release the snap, freeing the aerial steel structure receiving platform from the current axis's positioning reference. Then, the aerial steel structure receiving platform, track, and sliding trolley are moved along the translation guide to the corresponding position on the next axis. During the translation, the guide's constraint ensures the entire tooling system does not deviate from the preset direction, preventing collisions with the frame beams and columns.

[0101] Upon reaching the next axis position, calibration is performed using the tooling positioning benchmark as a reference: if it is a positioning pin structure, adjust the position of the receiving platform so that the bottom positioning hole aligns with the positioning pin; if it is a positioning plate, fine-tune the position by observing the alignment of the platform edge with the positioning plate benchmark line until the track direction corresponds to the preset placement point of the next axis, ensuring the accurate transfer path of subsequent equipment modules. After calibration, use the quick-locking components to fix the receiving platform. For bolt-type structures, tighten the locking bolts; for snap-on structures, fasten the snaps, forming a firm connection between the receiving platform and the frame to bear the weight of subsequent equipment modules. After fixing, repeat the steps of hoisting the equipment module to the sliding trolley, sliding, pulling to the placement point, and assembling and welding to complete the placement of the large equipment on the next axis. The entire process does not require rebuilding the track and platform, significantly saving operation time in confined spaces.

[0102] In some implementations, a built-in reference mark is provided next to the preset placement point of the multi-layer frame, and the device module is provided with an alignment detection structure adapted to the built-in reference mark; S5 also includes the following steps before assembling and mating the device module:

[0103] After placing the upper and lower equipment modules at the preset docking positions, the positional deviation of the equipment modules relative to the inherent reference mark is read through the alignment detection structure.

[0104] Adjust the height and horizontal position of the lower equipment module according to the positional deviation, so that the assembly joints of the upper and lower equipment modules are aligned along the preset docking trajectory, and then welded and fixed.

[0105] When assembling and mating equipment modules within a confined, multi-layered frame, even minute positional deviations can lead to misalignment, increasing welding difficulty and even affecting equipment performance. Therefore, precise calibration can be achieved using fixed benchmarks and testing structures. The inherent benchmark markings next to the pre-set positioning points are fixed references set based on the inherent structure of the multi-layered frame. These are typically machined directly onto the surface of beams and columns surrounding the pre-set positioning points during the early stages of frame construction or equipment installation. For example, they may be made by stamping cross lines with steel or welding small, flat steel marker blocks. These markings are firmly integrated with the frame structure and will not shift due to operational vibrations, and their positions match the designed docking dimensions of the equipment modules.

[0106] The alignment detection structure on the equipment module is a simple measuring component adapted to the inherent reference mark. It can be selected according to the module size and operation requirements. For example, a right-angle ruler can be installed on the edge of the mating end face of the module; or a small laser pointer can be fixed on the top surface of the module. The thin laser beam emitted by the pointer can be directly pointed to the inherent reference mark to achieve rapid alignment detection.

[0107] Before assembling the equipment modules in S5, the upper and lower sections of the equipment module are placed in their preset docking positions. The upper section is typically temporarily suspended and fixed using a hoist assembly of a single-beam crane, while the lower section is placed on a pre-erected temporary support. The height of the temporary support must be close to the designed docking height to allow for subsequent fine-tuning. At this point, the joints of the two equipment modules are not yet fully aligned, and the positional deviation needs to be read using an alignment detection structure.

[0108] Operators can obtain deviation information by observing the correspondence between the alignment detection structure and the inherent reference mark: if a right-angle ruler is used, one right-angled edge of the ruler is pressed against the mating end face of the equipment module, and the other right-angled edge is aligned with the crosshair of the inherent reference mark. The horizontal or vertical offset is judged by the gap between the edge of the ruler and the crosshair; if a laser pointer is used, the deviation between the point where the laser beam lands on the inherent reference mark and the center of the mark is observed to determine whether the height or horizontal position of the module is accurate.

[0109] Based on the positional deviation read, the lower equipment module is fine-tuned. Height deviations can be corrected by adjusting temporary supports, such as by placing thin steel plates under the supports to increase height, or by using jacks to lift the equipment module and then removing some support material to lower its height. Horizontal deviations are corrected by inserting a pry bar into the gap between the bottom of the equipment module and the support, slowly adjusting the module's position. During fine-tuning, the alignment detection structure is continuously used for comparison until the edge of the ruler is completely aligned with the benchmark marking line, or the laser beam falls on the center of the marking. At this point, the assembly joints of the upper and lower equipment modules are aligned along the preset docking trajectory, with uniform and tight joint gaps. Welding then ensures welding quality and avoids welding defects caused by misalignment. This calibration method, utilizing a fixed benchmark and detection structure, achieves accurate alignment in environments with limited operating space without the need for large measuring equipment, simplifying the assembly process and improving the reliability of equipment module connections.

[0110] The assembly and mating of equipment modules can be made more efficient with the help of simple auxiliary tools. Positioning pin holes are pre-set on the mating edges of the upper and lower equipment modules. During assembly, the tapered positioning pin is first inserted into the pin hole of the lower module, and the corresponding pin hole of the upper module is aligned with the positioning pin before being slowly lowered, achieving initial positioning. Simultaneously, adjusting bolts are installed on the side of the modules. One end of the bolt is tightened against the frame beam, and the other end is connected to the equipment module. The position of the equipment module is finely adjusted by rotating the bolts to ensure a uniform gap at the joint. For large modules, temporary support jacks can be installed on both sides of the joint. The height of the equipment module can be adjusted by raising and lowering the jacks to assist in accurate alignment. These auxiliary structures require no complex operation, are easy to install and disassemble in confined spaces, and effectively reduce the difficulty of aligning the joints.

[0111] In some implementations, the inherent beam and column surfaces of the multi-layer frame are provided with hoisting attitude calibration references; the step of hoisting the equipment module to the sliding trolley in S3 includes:

[0112] When the equipment module is lifted by hoisting equipment and moved above the high-altitude steel structure receiving platform, the force distribution of the lifting points of the equipment module is adjusted with reference to the hoisting posture calibration benchmark, and the horizontal posture and placement angle of the equipment module are calibrated.

[0113] After the device module's orientation is adapted to the bearing surface of the sliding trolley, the device module is placed inside the sliding trolley, ensuring that the device module and the bearing surface of the sliding trolley are fully in contact.

[0114] The inherent beams and columns of a multi-story frame are the load-bearing components that constitute the frame structure. They are typically concrete or steel columns, suitable as reference benchmarks for hoisting operations. The hoisting posture calibration benchmark is a fixed reference mark set based on these inherent beams and columns. This can be achieved by painting conspicuous crosshairs on the beam / column surface or welding small metal reference blocks. The position of the hoisting posture calibration benchmark can be determined by combining the height of the high-altitude steel structure receiving platform and the working angle of the hoisting equipment, allowing operators to observe the relative positional relationship between the benchmark and the equipment module from the ground or platform edge.

[0115] In confined spaces, if the hoisting equipment module is tilted or angularly deviated after being lifted in mid-air, placing it directly onto the sliding trolley may cause the module to slip or fail to make proper contact with the trolley's bearing surface, affecting subsequent sliding stability. Therefore, it is crucial to adjust the equipment module's attitude in real time, using the hoisting attitude calibration benchmark on the existing beams and columns as a reference.

[0116] During the S3 operation of hoisting the equipment module onto the sliding trolley, the hoisting equipment lifts the module using slings and slowly moves it above the high-altitude steel structure receiving platform. At this point, the boom movement is paused, and attitude calibration begins. The operator uses the hoisting attitude calibration benchmark on the beam / column surface as a reference to observe the horizontal attitude and placement angle of the equipment module. If the edge line of the module's top surface is not parallel to the horizontal marking on the benchmark, it indicates that the equipment module is tilted; if the preset marking on the side of the equipment module is misaligned with the vertical marking on the benchmark, it indicates a deviation in the placement angle.

[0117] Upon detecting a posture deviation, calibration is performed by adjusting the force distribution at the lifting points of the equipment module. For example, if one side of the equipment module is too high, the length of the sling on that side is shortened or the contact position of the sling at the lifting point is adjusted to increase the force on that side, gradually restoring the equipment module to a horizontal position. If the placement angle is off, the rotation direction of the boom is finely adjusted using the lifting equipment, while simultaneously adjusting the force balance of the slings on both sides to guide the equipment module to rotate to the correct angle. During the calibration process, the relative position of the equipment module to the lifting posture calibration reference is continuously observed until the posture of the equipment module matches the bearing surface of the sliding trolley—that is, the bottom surface of the equipment module remains horizontal, and the placement direction is consistent with the extension direction of the bearing surface of the sliding trolley.

[0118] After confirming the attitude fit, the hoisting equipment is slowly lowered, gradually bringing the bottom surface of the module close to the bearing surface of the sliding trolley. During lowering, the slings are kept under slight tension to prevent the module from shifting due to gravity impact. Once the module is fully in contact with the trolley's bearing surface, the slings are completely released, completing the high-altitude rotation of the module. This attitude calibration method, based on existing beams and columns, eliminates the need for additional calibration supports, is convenient to operate in confined spaces, effectively ensures the stability of the module, and provides a reliable foundation for subsequent sliding operations.

[0119] In some implementations, the following steps are included before the sliding trolley slides along the track in step S4:

[0120] Using the inherent beams and columns of the multi-layer frame as a reference, mark the safe sliding path of the sliding trolley and determine the minimum safe distance between the equipment module and each beam and column;

[0121] During the sliding process, the relative position of the equipment module and the inherent beams and columns is obtained. Combined with the marking of the safe sliding path and the minimum safe distance, the sliding direction of the sliding trolley is adjusted.

[0122] The inherent beams and columns of the multi-layered frame serve as reliable references for the sliding operation. These beams and columns, typically made of concrete or steel, generally exhibit minimal surface sway, providing a stable benchmark for path marking. The safe sliding path is a pre-defined trajectory for the sliding trolley to move the equipment module. It must avoid protruding parts of the beams and columns and other obstacles within the frame, ensuring that the equipment module maintains a safe distance (minimum safe clearance) from the surrounding structure throughout the movement. The minimum safe clearance is the space that must be maintained between the equipment module and the beams and columns. Its size can be determined based on the shape of the equipment module and the cross-sectional shape of the beams and columns, ensuring that even slight swaying will not result in a collision.

[0123] Before the sliding trolley moves along the track, path marking and spacing determination must be completed. Using existing beams and columns as references, operators visually observe or use a level to draw lines for the safe sliding path on the platform surface or ground beside the track using white lime powder. The lines must be consistent with the track's direction of extension, avoiding beams and columns to form a continuous travel trajectory. Furthermore, by directly comparing the relative dimensions of the equipment module and the beams and columns, the minimum safe distance between them is determined, ensuring sufficient spacing to accommodate possible slight deviations and prevent collisions.

[0124] Once the sliding process begins, operators must continuously monitor the relative position of the equipment module and the existing beams and columns. This can be done visually from the platform edge or by setting temporary markers beside the track. The distance between the marker and the beam / column should be equal to the minimum safe clearance. When the equipment module approaches the marker, an adjustment is required. If the distance between the equipment module and a beam / column is close to the minimum safe clearance, or if it deviates from the preset safe sliding path markings, the direction of the sliding trolley should be slowly adjusted. If the equipment module is biased towards the left beam / column, the right side of the trolley can be gently pushed to shift the module to the right; if it is biased towards the right beam / column, the left side of the trolley should be pushed while maintaining the overall direction of movement of the sliding trolley along the track.

[0125] This method of marking the path first and then adjusting it in real time effectively avoids the risk of collisions between equipment modules and existing beams and columns in confined spaces. The stable reference provided by the existing beams and columns allows for more accurate marking of the safe sliding path, while the pre-determination of the minimum safe distance provides a clear basis for judgment during the sliding operation. Combined with real-time observation and directional adjustments during the sliding process, the movement of the equipment module driven by the sliding trolley is more stable and controllable, creating favorable conditions for the subsequent accurate docking of the equipment module with the hoist assembly.
