Description

Technical Field

[0001] This invention belongs to the field of power equipment installation technology, specifically relating to an auxiliary device and method for installing a steel structure of a power distribution cabinet. Background Technology

[0002] As a critical piece of equipment in power transmission and distribution systems, the installation quality of the steel structure of power distribution cabinets in substations, data centers, and other locations directly affects the safe and stable operation of the entire power system. Traditional installation methods mainly rely on large machinery such as cranes and hydraulic forklifts combined with manual labor for positioning and leveling. This process not only requires multiple people to work together, posing high safety risks, but also makes precision control difficult. Especially in scenarios with limited installation space or requiring the precise assembly of multiple cabinets, it is difficult to guarantee the accurate elevation and level of the cabinets in three-dimensional space, creating potential hazards for subsequent busbar connections and equipment commissioning.

[0003] While existing technologies offer some lifting or adjustment devices for equipment installation, such as simple screw jacks or support frames with basic lifting functions, they generally have low levels of automation and heavily rely on operator experience. During adjustment, operators must repeatedly measure and manually correct using tools like spirit levels and measuring tapes, resulting in low efficiency and difficulty in achieving precise dynamic control. Furthermore, these devices are functionally limited, lacking real-time monitoring and intelligent feedback capabilities. They cannot detect the actual load and posture changes of the cabinet during lifting, nor can they achieve coordinated installation and data linkage between multiple distribution cabinets. Consequently, they fail to meet the high-efficiency, high-precision, and digital requirements of modern smart grid construction for power distribution equipment installation.

[0004] Therefore, the present invention proposes an installation auxiliary device and installation method for the steel structure of power distribution cabinet to at least partially solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, this invention provides an auxiliary device and method for installing steel structures of power distribution cabinets, which solves the problems of difficulty in precision control, low degree of automation, and difficulty in achieving collaborative operation of multiple cabinets caused by the reliance on manual experience and simple tools in the traditional installation of power distribution cabinets.

[0006] The objective of this invention can be achieved through the following technical solution: an installation auxiliary device for a steel structure of a power distribution cabinet, comprising a power distribution cabinet body and a support and guide assembly. The power distribution cabinet body is provided with a connection structure for connecting to an intelligent lifting mechanism. The support and guide assembly includes an outer sleeve fixed to the installation foundation, and the outer sleeve is provided with a guide rail that matches the connection structure. The intelligent lifting mechanism includes a mechanical drive unit, a status sensing unit, and a central control module electrically connected to the mechanical drive unit and the status sensing unit respectively. The mechanical drive unit includes a servo motor and a transmission mechanism driven by the servo motor, and the transmission mechanism is in transmission cooperation with the connection structure of the power distribution cabinet body. The status sensing unit includes a height sensor disposed on the power distribution cabinet body for measuring lifting displacement, and a multi-axis horizontal tilt sensor disposed on the power distribution cabinet body for measuring levelness. The central control module is configured to execute an adaptive control algorithm, and dynamically control the servo motor based on the deviation between the real-time feedback data of the height sensor and the horizontal tilt sensor and the preset target data, so as to drive the power distribution cabinet body to automatically adjust its lifting and horizontal posture along the guide rail.

[0007] As a preferred embodiment of the present invention, the adaptive control algorithm is a PID control algorithm or a fuzzy PID control algorithm.

[0008] As a preferred embodiment of the present invention, the central control module also integrates a wireless communication unit for data interaction with at least one other installation system of the same structure.

[0009] As a preferred embodiment of the present invention, the system receives instructions from a central control terminal via a wireless communication unit; the central control terminal is used to uniformly manage multiple installation systems and, based on the overall installation digital model of the power distribution cabinet, issues independent or coordinated lifting target data to the central control module of each system.

[0010] As a preferred embodiment of the present invention, the state sensing unit further includes a pressure sensor disposed at the bottom of the support guide assembly. The pressure sensor is connected to the central control module and is used to monitor the load of the power distribution cabinet body in real time.

[0011] An installation method for a steel structure of a power distribution cabinet includes the following steps: Step S1: Import the digital installation model containing the precise three-dimensional coordinates, elevation, and installation tolerances of the power distribution cabinet into the central control terminal through the building information modeling interface. Step S2: Secure the support guide assembly to the mounting base; Step S3: Connect the power distribution cabinet body to the support guide assembly, and start the intelligent lifting mechanism and control assembly; Step S4: The central control terminal sends target instructions to the central control modules of each system according to the digital installation model. The central control module executes an adaptive control algorithm, integrates multi-source data from height sensors, horizontal tilt sensors and pressure sensors, and controls the power distribution cabinet body to automatically rise and fall to the target height and horizontal posture in a closed loop. Step S5: Fix the power distribution cabinet body in its final installation position; Step S6: After the fixation is completed, remove the support guide assembly, intelligent lifting mechanism and control assembly.

[0012] As a preferred technical solution of the present invention, in step S4, the central control module uses the multi-axis horizontal tilt sensor and the pressure sensor to continuously monitor the attitude and force balance of the power distribution cabinet and make real-time fine adjustments.

[0013] As a preferred embodiment of the present invention, during the lifting process in step S4 or the final alignment process in step S5, the central control module performs closed-loop control based on the feedback data from the pressure sensor to ensure balanced force distribution.

[0014] The beneficial effects of this invention are as follows: Precise lifting and lowering are achieved through a mechanical drive unit consisting of a servo motor, transmission mechanism, and guide rail; multi-source data acquisition is performed by a state perception unit composed of height sensors, horizontal tilt sensors, and pressure sensors; and an adaptive control algorithm is executed by a central control module, constructing a fully closed-loop intelligent control system. This enables automatic and precise adjustment of the elevation and horizontal attitude of the power distribution cabinet in three-dimensional space. Simultaneously, through the collaboration of the wireless communication unit and the central control terminal, multi-cabinet collaborative installation based on a BIM digital model is supported. This not only significantly improves installation accuracy and work efficiency, effectively avoiding repeated manual adjustments, but also ensures the safety and reliability of the operation process through real-time monitoring of load and attitude, meeting the high standards of digitalization, automation, and intelligence required for power distribution equipment installation in modern power engineering construction.

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0021] Example 1 This embodiment provides an auxiliary device for installing the steel structure of a power distribution cabinet. Please refer to [link / reference]. Figure 2 The figure is a schematic diagram of an installation auxiliary device for a power distribution cabinet steel structure according to the present invention. This device is mainly used for high-precision automated installation of the power distribution cabinet steel structure in substations, data centers, industrial plants, and other similar locations.

[0022] The device mainly includes a power distribution cabinet body 100, a support and guide assembly, and an intelligent lifting mechanism. The power distribution cabinet body 100 is the target installation object, and its structure and dimensions are determined according to the specific power system design. This invention has wide applicability and can adapt to cabinets of different specifications; that is, the corresponding structure and dimensions can be designed according to the specific specifications of the cabinet. To achieve reliable connection and transmission with the intelligent lifting mechanism of this invention, a connecting structure 200 is specially provided on the side wall or bottom frame of the power distribution cabinet body 100. In a preferred embodiment, the connecting structure 200 is a rack and pinion structure. The rack is arranged vertically along the lifting direction of the cabinet, and its tooth profile, module, and other parameters are precisely matched with the transmission mechanism 500 in the intelligent lifting mechanism to ensure smooth transmission, no slippage, and accurate positioning during lifting. The connecting structure 200 can be integrally formed on the cabinet frame or it can be a separate component firmly fixed to the cabinet by high-strength bolts or other means. Its material is typically high-strength wear-resistant alloy steel to bear the weight of the cabinet and ensure long-term reliability.

[0023] The support and guide assembly serves as the base and guide frame for the entire device, its core function being to provide a stable and precise motion reference for the lifting and lowering of the power distribution cabinet body 100. This assembly includes an outer sleeve 300 fixed to the mounting foundation and a guide rail 400 mounted on the outer sleeve 300. The outer sleeve 300 is typically welded from thick-walled steel pipes or structural steel, possessing sufficient rigidity and strength. Its bottom features a flange structure, allowing it to be securely fixed to a concrete foundation or embedded steel plate using anchor bolts or chemical anchors, ensuring no displacement or overturning occurs when bearing the cabinet load. The guide rail 400 is a key component for achieving precise vertical movement, engaging with corresponding sliders or rollers on the power distribution cabinet body 100. The connection between the guide rail 400 and the outer sleeve 300 requires precise calibration to effectively prevent horizontal swaying, offset, or rotation during lifting and lowering, providing a stable foundation for subsequent attitude adjustments.

[0024] The intelligent lifting mechanism is one of the core components of this invention, endowing the device with automated and intelligent functions. This mechanism consists of three main parts: a mechanical drive unit, a status sensing unit, and a central control module. These three parts are electrically connected to form a complete closed-loop control system. Please refer to the relevant documentation. Figure 3 The figure is a schematic diagram of the intelligent control process of an installation auxiliary device for a power distribution cabinet steel structure according to the present invention.

[0025] The mechanical drive unit provides the power for the lifting motion. It includes a servo motor and a matching transmission mechanism 500. In this embodiment, an AC servo motor is preferred due to its advantages such as fast response speed, high control precision, strong overload capacity, and the ability to achieve precise position, speed, and torque control. The servo motor has a built-in high-resolution encoder, which can provide real-time feedback of the precise position and speed of the motor rotor to the central control module. The transmission mechanism 500 converts the rotational motion of the servo motor into the linear vertical motion of the power distribution cabinet body 100. In this embodiment, the transmission mechanism 500 specifically consists of a reducer and an output gear coaxially connected to the servo motor. This gear meshes with the aforementioned connection structure 200 mounted on the cabinet, forming a high-precision rack and pinion transmission system. By precisely controlling the rotation angle and number of turns of the gear through the servo motor, micron-level precise control of the cabinet's lifting displacement can be achieved.

[0026] In a rack and pinion transmission system, unavoidable meshing backlash may exist between the gear and the rack. During the natural descent of the power distribution cabinet body 100, the rack drives the gear to rotate. At this time, the upper side of the gear teeth contacts the rack, while a gap exists on the lower side. When one side of the cabinet descends too quickly, the central control module adjusts the gear rotation by driving a servo motor to balance the descent speed. For example, when the right side of the cabinet descends too quickly, the drive gear rotates clockwise to slow down the right-side descent; when the left side of the cabinet descends too quickly, the drive gear rotates counterclockwise to accelerate the right-side descent. Because of the gap on the lower side of the teeth, a compensation amount needs to be added to the gear drive to eliminate the effect of the gap. This compensation amount can be calibrated by testing the gap between the gear and the rack beforehand to ensure control accuracy. This gap compensation mechanism enables the rack and pinion transmission to achieve fine-tuning of the horizontal attitude through the coordinated action of multiple devices, based on two-dimensional vertical motion.

[0027] The status sensing unit is responsible for real-time monitoring of various key status parameters of the power distribution cabinet body 100. It includes at least a height sensor and a multi-axis tilt sensor mounted on the power distribution cabinet body 100. The height sensor is used to accurately measure the current absolute or relative vertical displacement of the cabinet. Optional sensor types include, but are not limited to, laser displacement sensors, wire-type displacement sensors, or displacement values ​​calculated by reading servo motor encoder data and combining it with the transmission ratio. The multi-axis tilt sensor, typically a digital sensor based on MEMS technology, is mounted on the top or bottom frame of the cabinet. It can simultaneously measure the tilt angle of the cabinet relative to the absolute horizontal plane in both the X and Y axes in real time, with an accuracy of 0.01 degrees or even higher, providing core data for the automatic leveling of the cabinet. In a preferred embodiment, the status sensing unit also includes a pressure sensor located at the bottom of the support guide assembly. This pressure sensor, such as a high-precision weighing module, is used to monitor the total load of the entire device in real time, thereby indirectly reflecting the weight distribution of the power distribution cabinet body 100. When multiple devices of this invention are used to install a large cabinet, by comparing the data from the pressure sensors at each support point, it can be determined whether the cabinet is under balanced stress, thus preventing structural deformation or excessive installation stress caused by uneven stress.

[0028] Attitude fine-tuning is achieved by configuring at least two independent installation aids for each power distribution cabinet. These aids are evenly distributed along the bottom of the cabinet, and the guide rails of each aid are precisely calibrated to ensure vertical movement. Multi-axis tilt sensors monitor the cabinet's levelness in real time, and the central control module calculates the height deviation of each support point based on the sensor feedback data and sends differentiated lifting commands to the servo motors of each aid. For example, when the left end of the cabinet is too low, the left-end aid is raised by a tiny distance (e.g., 0.3 mm). Through micron-level precise control of the gear and rack transmission of each aid, the cabinet's horizontal attitude is automatically adjusted.

[0029] The central control module is connected via cables to the servo driver of the mechanical drive unit and various sensors of the state sensing unit. The core function of the central control module is to execute a preset adaptive control algorithm. It receives real-time feedback data streams from the state sensing units (height sensor, tilt sensor, pressure sensor) and compares them in real-time with preset target data (target height, target horizontal attitude) from the central control terminal, calculating the deviation value. Then, based on this deviation value, it dynamically generates control commands by executing an adaptive control algorithm and sends them to the servo motor driver. The servo driver precisely controls the speed, direction, and rotation angle of the servo motor according to these commands, thereby driving the transmission mechanism 500 to move the power distribution cabinet body 100 for lifting, lowering, and fine-tuning of its attitude, until the deviation between the feedback data from all sensors and the target data is reduced to within a preset tolerance range, for example, a height error of less than ±0.5mm and a tilt error of less than ±0.02°, forming a complete, efficient, and precise closed-loop control circuit.

[0030] As a preferred embodiment of the present invention, the adaptive control algorithm can be a classic PID (proportional-integral-derivative) control algorithm or a more advanced fuzzy PID control algorithm. The PID control algorithm generates the control quantity by performing proportional, integral, and derivative operations on the deviation, and has the advantages of simple algorithm, good robustness, and high reliability, making it suitable for linear or near-linear control objects. The fuzzy PID control algorithm, on the other hand, combines fuzzy logic and PID control, and can simulate human experience and reasoning. It has better adaptive capability and control performance for complex systems with strong nonlinearity and time-varying characteristics, such as changes in friction and center of gravity shifts that may occur during the lifting and lowering of the cabinet, enabling a faster and smoother adjustment process and effectively avoiding overshoot and oscillation.

[0031] To enable collaborative installation of multiple cabinets side-by-side, the central control module of this invention preferably integrates a wireless communication unit, such as a Wi-Fi or 5G communication module. Through this wireless communication unit, the central control module of a single installation device can interact with at least one other installation system of the same structure in real time, sharing status information such as height, tilt angle, and load, thus achieving distributed collaborative control. Furthermore, all installation systems receive commands from a central control terminal via the wireless communication unit. This central control terminal can be a portable industrial tablet or a host computer deployed in the control room. It possesses a powerful human-machine interface and data processing capabilities for unified management of all installation systems on-site. Operators can import the overall installation digital model of the power distribution cabinet through this terminal. The model includes the precise coordinates, elevation, and installation tolerances of each cabinet in three-dimensional space. The central control terminal analyzes the model and sends independent or collaborative lifting target data to the central control module of each installation system; for example, cabinet A is raised to height H1, cabinet B is raised to height H2, while keeping their tops level. This centralized management and decentralized control architecture greatly simplifies installation and deployment in complex scenarios, enabling precise mapping from digital models to physical entities.

[0032] Example 2 This embodiment provides an installation method for the steel structure of a power distribution cabinet using the aforementioned installation auxiliary device. This method deeply integrates digital design with automated construction, achieving intelligent, high-precision, and high-efficiency installation. Please refer to... Figure 1 The figure is a schematic flowchart illustrating the steps of an installation method for a steel structure of a power distribution cabinet according to the present invention. The installation method specifically includes the following steps: Step S1: Import the digital installation model. Before the installation work begins, the digital installation model file, containing the precise three-dimensional coordinates, elevation, installation sequence, and installation tolerance requirements of the power distribution cabinets, is first imported into the central control terminal via the Building Information Modeling (BIM) interface. The software system of the central control terminal parses the model, extracts the unique identifier, target spatial location (X, Y, Z coordinates), and posture requirements (levelness) of each cabinet to be installed, and generates the corresponding installation task sequence and target dataset. This step achieves lossless transfer of design data, ensuring the accuracy benchmark of the installation from the source, replacing the traditional method of relying on paper drawings and manual on-site marking and positioning.

[0033] Step S2: Secure the support and guide components. Based on the precise positions displayed on the central control terminal or calibrated on-site using surveying equipment such as a total station, firmly fix the bases of one or more support and guide components to the installation foundation. The fixing work must ensure that the components are accurately positioned and securely installed, providing a stable guarantee for subsequent load-bearing and guidance.

[0034] Step S3: Connect the cabinet and components, and start the system. Using auxiliary equipment such as cranes and forklifts, initially hoist the power distribution cabinet body 100 into position, aligning it with the support guide assembly. Engage and connect the connecting structure 200 on the cabinet with the guide rail 400 and transmission mechanism 500 on the support guide assembly. After connection, turn on the power to all intelligent lifting mechanisms, start each central control module and sensor, and the system enters standby mode. At this time, the interface of the central control terminal will display the online status and initial readings of all connected devices.

[0035] Step S4: Perform automatic alignment and fine-tuning. This is the core intelligent step of the entire installation method. The operator selects the target cabinet and issues an automatic installation command on the central control terminal. Based on the digital installation model analyzed in Step S1, the central control terminal issues precise target height and horizontal attitude commands to the central control modules of one or more installation systems connected to the cabinet. Upon receiving the commands, each central control module immediately starts a closed-loop control program. They execute built-in adaptive control algorithms and begin to integrate multi-source real-time data from their respective state sensing units: height sensors measure the current height, multi-axis horizontal tilt sensors measure the current attitude, and pressure sensors monitor the current load. The central control module compares these real-time feedback data with the received target commands and calculates the height difference and tilt difference. Based on the deviation, the algorithm calculates the optimal control quantity in real time, driving the servo motor to rotate at a precise speed and direction, and through the transmission mechanism 500, automatically raising and lowering the cabinet along the guide rail 400. If a cabinet is supported by multiple devices, the central control modules work collaboratively via wireless communication units. They independently adjust the height of their respective support points to achieve overall cabinet lifting and lowering, and also perform differential adjustments based on feedback from tilt sensors to precisely correct the cabinet's horizontal orientation. Simultaneously, throughout the lifting and leveling process, the central control module continuously monitors the cabinet's posture stability and stress balance using data from multi-axis tilt and pressure sensors, making real-time fine-tuning to ensure a smooth and safe process. This closed-loop control process continues until all sensor feedback values ​​fall within the preset target tolerance range, at which point the system automatically stops moving and locks its position.

[0036] Step S5: Final Fixing. Once the central control terminal displays that the cabinet has reached the predetermined installation position and posture, and its status is stable, the installers can proceed with the final fixing work. This includes welding or bolting the base of the power distribution cabinet to the foundation embedded parts, and completing the parallel connection between cabinets. During the final alignment and tightening process, if a slight change in the cabinet's posture is found due to factors such as tightening force, the operator can manually fine-tune it through the central control terminal, or trigger the automatic alignment program again. During this process, the central control module continuously performs closed-loop control based on feedback data from pressure sensors to ensure that the cabinet remains under balanced stress after tightening, avoiding installation stress.

[0037] Step S6: Remove auxiliary components. After the power distribution cabinet body 100 is completely and securely fixed, and its installation quality is confirmed to meet design requirements through final acceptance, the installation auxiliary device of this invention can be removed. The installer first separates the transmission mechanism 500 from the cabinet connection structure 200, and then sequentially removes and moves the intelligent lifting mechanism, control components, and support guide components. These removed components are all standardized and modular in design, and can be easily transported to the next installation station or the next project site for reuse, demonstrating good economic efficiency.

[0038] In summary, the installation auxiliary device and method for the steel structure of a power distribution cabinet disclosed in this invention have significant beneficial effects. Through a mechanical drive and guiding unit consisting of a servo motor, a high-precision transmission mechanism 500, and a guide rail 400, precise control of the cabinet's lifting and lowering motion is achieved. Combined with a multi-dimensional state perception unit composed of a height sensor, a multi-axis horizontal tilt sensor, and a pressure sensor, comprehensive and real-time quantitative monitoring of the cabinet's spatial position, attitude, and stress state is performed. Furthermore, utilizing a central control module equipped with an adaptive control algorithm, a fully closed-loop intelligent control system is constructed, from command issuance to state perception and action execution. This system enables automated and high-precision adjustment of the power distribution cabinet's elevation and horizontal attitude in three-dimensional space, completely eliminating reliance on operator experience.

[0039] Meanwhile, by introducing a collaborative working mode between the wireless communication unit and the central control terminal, this invention supports the collaborative installation of complex multi-cabinet systems based on digital models such as BIM, achieving seamless integration of design and construction. This not only significantly improves installation accuracy and operational efficiency, effectively avoiding the inefficient work of repeated measurements and adjustments in traditional methods, but also provides early warnings and proactive interventions for dangerous conditions such as overload and tilt by real-time monitoring of load and attitude changes, greatly ensuring the safety and reliability of the operation process. This invention fully meets the stringent standards for digitalization, automation, intelligence, and high safety in the installation of power distribution equipment in high-end engineering fields such as modern smart grid construction and large data centers.
