Description

Technical Field

[0001] This utility model relates to the field of main control cabinets, and more specifically, it relates to a main control cabinet for a quick-installation unmanned tower crane. Background Technology

[0002] With the deep integration of industrialization and intelligence in construction, unmanned tower cranes are increasingly widely used in large-scale engineering construction due to their advantages of high efficiency, safety and precision. The main control cabinet, as the "nerve center" of the unmanned tower crane, needs to integrate three core functional modules: data acquisition, model calculation and collaborative control. Its assembly efficiency and operational stability directly determine the tower crane's response speed and operational accuracy.

[0003] Currently, the various functional cabinets of the existing main control cabinet (i.e., the data acquisition cabinet, the model calculation cabinet, and the collaborative control cabinet) are complicated in terms of positioning during the assembly process with the frame due to the lack of a positioning structure. This results in long installation times and makes it difficult to meet the needs of rapid deployment on construction sites. At the same time, the wiring between the cabinets is mostly laid out externally, which not only makes the wiring messy and susceptible to interference from the external environment, affecting the stability of signal transmission, but also increases the difficulty of later inspection and maintenance.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a main control cabinet for a quick-installation unmanned tower crane. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a main control cabinet for a quick-installation unmanned tower crane.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation unmanned tower crane main control cabinet, comprising three cabinets—a data acquisition cabinet, a model calculation cabinet, and a collaborative control cabinet—for collaboratively ensuring the operation of the unmanned tower crane, and a frame for assembling the three. Through slots are provided between the cabinets for connecting the wiring between them. A power module is installed at the bottom of the frame, and multiple positioning rods extending from the bottom of the frame into the frame are installed above the power module. Each of the three cabinets has a positioning slot that matches the positioning rod. The three cabinets are positioned by aligning their positioning slots with the positioning rods and inserting them one by one. The positioning rods are hollow inside to accommodate the power supply lines of the power module, which supply power to the components inside the three cabinets. A locking assembly is installed at the head of the positioning rod. After the three cabinets are positioned, the locking assembly fixes them relative to the frame, completing the installation of the unmanned tower crane main control cabinet.

[0007] Preferably, the positioning rod has a recess on the opposite part of the three cabinets, and the power supply interface of the power supply line is installed in the recess.

[0008] Preferably, the locking assembly includes a screw fixed to the positioning rod, and a nut is threaded onto the outer side wall of the screw.

[0009] Preferably, a cast iron counterweight base is fixedly connected to the bottom of the power module.

[0010] Preferably, one side of the frame has three sets of ventilation slots A arranged in a vertical array, and after the three cabinets are assembled, ventilation slots B are provided on the parts that are aligned with the ventilation slots A on the frame.

[0011] Preferably, three sets of fans arranged vertically are embedded and fixed on the other side of the frame, and circular through slots are opened on the three cabinets at the points where they are aligned with the fans on the frame after assembly.

[0012] Preferably, the cast iron counterweight base is equipped with casters with locking function on all four sides of its bottom end.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model uses the positioning slots on the cabinet to align with the positioning rods inside the frame and insert them one by one. The precise cooperation between the positioning rods and the positioning slots achieves rapid positioning, forming a quick-assembly structure. After positioning, the three cabinets are firmly fixed to the frame by the locking components at the heads of the positioning rods, ensuring the structural stability after assembly. The power supply lines of the power module are run through the hollow positioning rods, orderly supplying power to the internal components of the three cabinets, avoiding the situation of exposed and messy lines, and solving the problems in the background technology.

[0015] 2. The cast iron counterweight base in this utility model utilizes the high density and sufficient weight of cast iron to effectively lower the overall center of gravity of the main control cabinet, enhance the cabinet's resistance to tipping under vibration, minor collisions, or uneven ground conditions that it may face on the construction site, and ensure the stable operation of internal precision components; while the cast iron counterweight base is equipped with universal wheels with locking function around its bottom, which facilitates flexible movement of the cabinet during installation, deployment, position adjustment, or maintenance.

[0016] 3. This utility model can quickly expel the hot air inside the cabinet through a fan, creating a negative pressure environment inside the cabinet. Driven by the negative pressure, the cold air from the outside will naturally and smoothly enter the cabinet through the aligned ventilation slots A and B, forming a highly efficient convection circulation of "exhausting heat first and then introducing cold air". The above heat dissipation method based on negative pressure can avoid airflow obstruction, allowing cold air to flow more fully through the heat-generating components inside the cabinet, significantly improving heat dissipation efficiency, effectively preventing the impact of excessive internal temperature on the operational stability of components such as data acquisition and model calculation, extending the service life of the equipment, and better adapting to the needs of long-term continuous operation of the unmanned tower crane main control cabinet.

[0024] like Figure 1-5 As shown, this utility model provides a quick-installation unmanned tower crane main control cabinet, including three cabinets 2: a data acquisition cabinet, a model calculation cabinet, and a collaborative control cabinet, which coordinate to ensure the operation of the unmanned tower crane, and a frame 1 for assembling the three. Through slots 203 are provided between the cabinets 2 for connecting the wiring between the three. A power module 3 is installed at the bottom of the frame 1, and multiple positioning rods 4 extending from the bottom of the frame 1 into the frame 1 are installed above the power module 3. Each of the three cabinets 2 has a positioning slot 5 that matches the positioning rod 4. The three cabinets 2 are positioned by aligning their positioning slots 5 with the positioning rods 4 and inserting them one by one. The positioning rod 4 is hollow inside to accommodate the power supply lines of the power module 3, which supply power to the components inside the three cabinets 2. A locking component 6 is installed at the head of the positioning rod 4. After the three cabinets 2 are positioned, the locking component 6 fixes them relative to the frame 1, completing the installation of the unmanned tower crane main control cabinet.

[0025] The frame 1 of this utility model serves as the assembly base, with the power module 3 at the bottom providing power to the entire cabinet. When assembling the three cabinets 2 (it should be noted that, to fully demonstrate the improved structure, the components inside each cabinet 2 are not shown), the positioning slots 5 on the cabinets 2 are aligned with the positioning rods 4 inside the frame 1 and inserted one by one. The precise cooperation between the positioning rods 4 and the positioning slots 5 achieves rapid positioning, solving the problems of complex positioning and time-consuming installation caused by the lack of a positioning structure in existing technologies, thus forming a quick-assembly structure. After positioning, the locking components 6 at the heads of the positioning rods 4 firmly fix the three cabinets 2 to the frame 1, ensuring the structural stability after assembly. The power supply lines of the power module 3 pass through the hollow positioning rods 4, orderly supplying power to the internal components of the three cabinets 2, avoiding exposed and messy wiring. Simultaneously, the cabinets 2 are connected by interconnected through slots 203, ensuring the smooth operation of the data acquisition cabinet and model calculation. The components within the data acquisition cabinet, collaborative control cabinet, and other three components work together. During operation, the data acquisition cabinet continuously collects various operational data from the unmanned tower crane in real time, including tower posture, lifting parameters, wind speed and direction, motor operating status, and images of the working environment, and transmits the data to the model calculation cabinet in real time. After receiving the data, the model calculation cabinet uses its built-in algorithm model for rapid analysis and processing, such as calculating real-time load safety thresholds based on the tower's mechanical model, predicting operational risks based on environmental data, and optimizing control parameters based on historical operational data, generating precise control commands. The collaborative control cabinet receives the control commands output by the model calculation cabinet, and coordinates the lifting, luffing, and slewing mechanisms of the tower crane in accordance with preset operating procedures and safety regulations. At the same time, it feeds back the execution status to the data acquisition cabinet and the model calculation cabinet, forming a closed-loop collaborative mechanism of "acquisition-analysis-control-feedback" to ensure that the unmanned tower crane can operate autonomously, safely, and efficiently under complex working conditions.

[0026] The locking assembly 6 includes a screw 601 fixed on the positioning rod 4, and a nut 602 is threaded onto the outer wall of the screw 601. When all three cabinets 2 are inserted into the positioning rod 4 for positioning, the screw 601 passes through the positioning groove 5 on the uppermost cabinet 2. At this time, the top of the cabinet 2 is flush with or slightly lower than the top of the positioning rod 4. Then, the nut 602 is rotated clockwise to install the nut 602 on the screw 601. The nut 602 moves downward along the screw 601 and slowly abuts against the top of the uppermost cabinet 2, thus fixing the three cabinets 2 to the frame 1.

[0027] Furthermore, the positioning rod 4 and the three cabinets 2 are all provided with recesses 401. The power supply interface 10 of the power supply line is installed in the recess 401 (the connector inside the cabinet 2 is inserted into the power supply interface 10 to supply power to the components inside the cabinet 2). The recess 401 structure can provide physical protection for the power supply interface 10, preventing damage to the interface due to collision or friction during the installation or use of the cabinet 2. In addition, the bottom end of the power module 3 is fixedly connected to a cast iron counterweight base 7, and the bottom end of the cast iron counterweight base 7 is equipped with universal wheels 8 with locking function. The cast iron counterweight base 7 utilizes the characteristics of high density and sufficient weight of cast iron to effectively lower the overall center of gravity of the main control cabinet, enhance the cabinet's anti-tipping ability in the environment of vibration, slight collision or uneven ground that the construction site may face, and ensure the stable operation of the internal precision components. The universal wheels 8 with locking function installed around the bottom end of the cast iron counterweight base 7 facilitate flexible movement of the cabinet during installation, deployment, position adjustment or maintenance.

[0028] Finally, this utility model provides three sets of ventilation slots A101 arranged in a vertical array on one side of the frame 1. After assembly, each of the three cabinets 2 has a ventilation slot B201 at the point where it aligns with the ventilation slots A101 on the frame 1. Three sets of fans 9 are embedded and fixed in a vertical array on the other side of the frame 1. Each of the three cabinets 2 has a circular through-slot 202 at the point where it aligns with the fans 9 on the frame 1. When the main control cabinet is assembled, the ventilation slots A101 on the frame 1 and B201 on the cabinets 2 are aligned, forming a channel for outside air to enter the cabinets 2. Simultaneously, the fans 9 on the frame 1 are also aligned with the circular through-slots 202 on the cabinets 2, allowing the fans 9 to directly pass through the circular through-slots 202. The through-slot 202 acts inside the cabinet 2, allowing the fan 9 to quickly expel the hot air inside the cabinet 2, creating a negative pressure environment inside the cabinet 2. Driven by the negative pressure, the outside cold air will naturally and smoothly enter the cabinet 2 through the aligned ventilation slots A101 and B201, forming a highly efficient convection circulation of "exhausting heat first and then introducing cold air". This heat dissipation method based on negative pressure can avoid airflow obstruction, allowing cold air to flow more fully through the heat-generating components inside the cabinet 2, significantly improving heat dissipation efficiency, effectively preventing the impact of excessive internal temperature on the operational stability of components such as data acquisition and model calculation, extending the service life of the equipment, and better adapting to the needs of long-term continuous operation of the unmanned tower crane main control cabinet.
