Description

Technical Field

[0001] This utility model relates to a multi-functional power distribution cabinet installation vehicle, belonging to the field of electromechanical installation technology. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] Typically, a crane lifts the distribution cabinet to the material platform, then a hydraulic forklift is used to move the equipment to the cabinet's channel steel base, and finally, pry bars are used to move the equipment into place. Furthermore, with current tight project deadlines, electromechanical installation is usually carried out before the civil engineering work is completed, resulting in poor working conditions. During the transfer of the distribution cabinet equipment, bumps and knocks frequently occur, sometimes damaging the cabinet body, handles, displays, switches, indicator lights, and other components. Subsequent disassembly and modification will affect the project schedule, and the installation quality is not as stable or reliable as original factory assembly. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a multi-functional power distribution cabinet installation vehicle, which can realize the transportation of power distribution cabinets on complex installation work surfaces, achieve non-destructive transportation, accurate positioning, reduce vibration and micro-adjustment, speed up the installation and ensure the installation quality.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] In a first aspect, this utility model provides a multi-functional distribution cabinet installation vehicle, including a vehicle body. The chassis of the vehicle body is provided with movable reinforcing crossbars and a traveling mechanism. The vehicle body is provided with upper and lower sets of body reinforcing crossbars. A lifting system and a fastening system are respectively installed at the upper and lower sets of body reinforcing crossbars.

The set of fastening guide rail one is slidably assembled between the two fastening guide rail two, and each fastening guide rail is provided with a sliding fastening buckle with a locking device.

[0007] Furthermore, the walking mechanism includes a triangular wheel, and the triangular wheel is isolated from the vehicle body by a shock-absorbing rubber pad.

[0008] Furthermore, the vehicle body is constructed using high-strength square steel tubing welded together, and has an overall cage-like structure.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0020] The following detailed description is exemplary and intended to provide further detailed explanation of the present invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this invention.

[0021] Example:

[0022] A multi-functional distribution cabinet installation vehicle includes a vehicle body 1, a walking mechanism, and a shock absorption system. The vehicle body 1 is constructed from high-strength square steel tubing, forming a cage-like structure to enclose the distribution cabinet and prevent damage from impacts. Each of the four uprights of the vehicle body 1 has a push handle 2. The chassis of the vehicle body 1 is equipped with movable reinforcing crossbars 4. Two sets of upper and lower reinforcing crossbars 3 are located in the middle of the vehicle body 1. A lifting system is installed at the higher reinforcing crossbar 3, while a fastening system is installed at the lower reinforcing crossbar 3. The lifting system, fastening system, and walking mechanism all have rubber vibration damping pads to reduce vibration to the equipment when traveling on uneven ground, thus protecting the electronic components inside the distribution cabinet.

[0023] In this embodiment, the lifting system includes a motor 9, a geared rail 8, a reducer, limiters 7, slide rails, and four lifting guide rails 14. The four lifting guide rails 14 form a square frame and are installed above the vehicle body reinforcement cross brace 3 at a high position. The square frame is adapted to the four columns of the vehicle body 1 and can slide up and down along the column direction. The geared rail 8 is installed at the upper column of the vehicle body 1, and limiters 7 are provided at both the upper and lower ends of the geared rail 8. The motor 9 with a reducer is installed at the lifting guide rail 14, and the output end of the motor 9 meshes with the geared rail 8. When the output end of the motor 9 rotates, the lifting guide rail 14 moves longitudinally under the action of the meshing force between the geared rail 8 and the motor 9. Two parallel lifting sliding crossbars 5 are installed at the lifting guide rail 14. The lifting sliding crossbars 5 are I-beams and have anti-detachment devices. Two slide rails are installed at the lifting sliding crossbars 5, and two displacement hooks 6 with safety locks are installed on each slide rail. The lifting system can move vertically up and down to lift the power distribution cabinet.

[0024] The fastening system includes a set of fastening guide rail 11 and a set of fastening guide rail 2 12. The set of fastening guide rail 2 12 is symmetrically installed at the four pillars of the vehicle body 1. The set of fastening guide rail 11 is slidably fitted between the two fastening guide rails 2 12. Each fastening guide rail 11 has two sliding fastening buckles 10. Each sliding fastening buckle 10 and the inner side of the fastening guide rail 1 (11) are provided with shock-absorbing rubber pads and locking devices. The fastening system can fix the position of the distribution cabinet, reduce shaking, and prevent the distribution cabinet from being damaged by bumps. The walking mechanism is a triangular wheel 13, which can cross obstacles such as channel steel base, threshold, and uneven ground.

[0025] In practical use, first push the installation vehicle to the distribution cabinet, open the movable reinforcing crossbar, and move the installation vehicle along the long side of the cabinet to enclose it. Lower and lock the movable reinforcing crossbar. Control the motor output to raise the distribution cabinet to the height of the movable reinforcing crossbar. Push the crossbar of the fastening system to clamp and lock the distribution cabinet. Push the installation vehicle to the cabinet base, align it with the installation position, and press the descent button to lower it into place. Compared to existing technologies, the multi-functional distribution cabinet installation vehicle in this solution can transport distribution cabinets, transport them across stairs, manually adjust the vehicle's position, and electrically hoist them into place. It also has vibration isolation and shock absorption functions. The hook of this installation vehicle can be adjusted to adapt to the transportation and installation of distribution cabinets of different sizes.

[0026] It should be noted that power distribution cabinets commonly suffer from technical deficiencies during transportation, such as incomplete vibration monitoring, static stress analysis, and poor environmental adaptability. Traditional solutions often use a single accelerometer for threshold alarms, failing to consider the coupling relationship between the dynamic characteristics of the transport vehicle and the cabinet's structural response. Existing technologies lack the fusion calculation of multi-physics parameters, making it impossible to accurately assess the fatigue damage risk of the cabinet structure under combined loads. Furthermore, conventional temperature compensation methods do not establish a correlation model with mechanical vibration parameters, resulting in potential misjudgments in the early warning mechanism. This solution further discloses a transportation detection scheme for power distribution cabinets installed in vehicles. This scheme constructs a vehicle-mounted transportation monitoring system based on multi-source information fusion, comprising three core algorithm modules:

[0027] 1. The embedded signal processor calculates the spectral entropy based on the vibration energy spectral entropy evaluation formula. The calculation formula is as follows:

[0028] H_v=-Σ(p_i·log2p_i)

[0029] In the formula: H_v is the vibration energy spectrum entropy, which reflects the complexity of vibration energy distribution and is used to assess the level of random vibration hazard; p_i is the proportion of vibration energy in each frequency band, which is obtained by the time domain signal from the MEMS accelerometers installed at the four corners of the cabinet, and divided into N characteristic frequency bands after FFT transformation.

[0030] II. The stress cloud map is updated in real time by the FPGA parallel computing unit based on the dynamic stress distribution reconstruction formula. The calculation formula is as follows:

[0031] σ_max=E·Σ(ε_j·W_j) / A

[0032] In the formula: σ_max is the maximum stress in the dynamic stress distribution reconstruction module, which characterizes the maximum stress concentration of the structure and guides the optimization of transportation speed; E is the elastic modulus of the cabinet material; ε_j is the measured value of the strain gauge group; W_j is the position weight coefficient; A is the area of ​​the characteristic section.

[0033] III. The edge computing gateway performs adaptive parameter compensation based on the temperature-vibration coupling correction formula. The calculation formula is as follows:

[0034] K_T=1+α·ΔT·(f_0 2 / f 2 )

[0035] In the formula: K_T is the temperature-vibration coupling correction coefficient, which is used to quantify the influence of temperature rise on the dynamic characteristics of the structure and correct the vibration warning threshold; α is the thermal expansion coefficient of the material; ΔT is the temperature rise measured by the temperature sensor; f_0 is the reference resonant frequency; f is the real-time frequency.

[0036] When the distribution cabinet is loaded onto the transport vehicle, the vibration sensor array collects three-dimensional acceleration data with a 50ms sampling period, and the signal processor calculates the current H_v value. When H_v exceeds the dynamic threshold, the transport vehicle's active suspension adjustment command is triggered. A monitoring network of 16 distributed strain gauges updates the stress distribution every 200ms. When σ_max reaches 70% of the material's yield strength, the path planning system automatically selects a low-vibration route. Temperature sensors monitor the temperature difference between the cabinet's surface and interior in real time. When the K_T correction coefficient deviates from the design range by 15%, the environmental control system activates a forced cooling mode.

[0037] This solution overcomes the limitations of traditional single-parameter monitoring, achieving multi-dimensional state perception during transportation. It improves the accuracy of identifying broadband random vibrations through vibration spectrum entropy quantification analysis, addresses the insufficient adaptability of traditional static modeling with dynamic stress reconstruction technology, and eliminates the influence of environmental factors on mechanical parameters through a temperature-coupled correction model. Compared to existing technologies, it offers advantages such as multi-physics collaborative analysis, dynamic optimization of transportation parameters, and advanced warning of structural damage, significantly improving the transportation safety and equipment reliability of precision power distribution cabinets.

Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones.
