Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and in particular to a vehicle-mounted control cabinet for mining trucks. Background Technology

[0002] A mining truck onboard control cabinet is an electrical control device used to manage and control the operation of mining trucks (i.e., mining trucks). As the "brain" of the mining truck, the onboard control cabinet integrates various control components and circuits, controlling and monitoring multiple key systems of the truck. The main functions of the onboard control cabinet include: power system control, used to adjust parameters such as engine speed and power output; transmission system control, used to achieve gear shifting control and transmission ratio adjustment; braking system control, used to control the truck's service brake and parking brake; and electrical equipment management, responsible for the power supply and control of electrical equipment such as lights, horns, and windshield wipers. The mining truck control cabinet mainly includes: a control unit composed of a microprocessor (MCU) or programmable logic controller (PLC), which has communication capabilities and can communicate with other systems of the mining truck (such as on-board monitoring systems, remote dispatching systems, etc.); a sensor interface for connecting different types of sensors (such as vehicle speed sensors, engine speed sensors, oil temperature sensors, oil pressure sensors, liquid level sensors, etc.), which convert the physical quantities (such as speed, temperature, pressure, etc.) of various systems of the mining truck into electrical signals and transmit them to the control unit through the sensor interface; an actuator interface through which the control unit connects actuators (such as solenoid valves, relays, motors, etc.); and a power module responsible for providing a stable power supply to the various components in the control cabinet, which typically includes circuits such as transformers, rectifiers, and voltage regulators.

[0003] Currently, mining trucks are mainly used in large open-pit mine operations. Mining trucks need to frequently transport ore and waste in complex terrain and harsh environments. The on-board control cabinet, as the control center of the whole vehicle, integrates precision components such as PLC, power modules, and communication equipment. It is subjected to strong vibration and impact, as well as the effects of high dust, large temperature difference, and high humidity for a long time, which can easily cause damage to its internal components and thus affect operations.

[0004] Currently, traditional mining truck control cabinets mostly employ simple passive protection by adding shock-absorbing pads to the bottom of the cabinet, creating ventilation holes, and installing ventilation fans. For example, Chinese utility model patent CN218277455U discloses a similar cabinet. However, these existing solutions have significant drawbacks: First, a single bottom shock absorber cannot effectively isolate all vibrations during the mining truck's operation, easily leading to damage to internal components due to prolonged vibration or loosening of electrical connections. Second, the traditional design of ventilation holes and fans easily becomes a channel for moisture intrusion in rainy or high-humidity environments, causing condensation inside the cabinet and resulting in circuit board corrosion, short circuits, and other malfunctions.

[0005] Therefore, it is necessary to design a mining truck-mounted control cabinet that can comprehensively solve the problems of vibration, heat dissipation and moisture-proof sealing, and has high reliability and active regulation of temperature and humidity inside the cabinet.

[0013] In one embodiment, the moisture-proof and breathable component includes an outer frame and a waterproof and breathable membrane disposed in the middle of the outer frame, wherein the waterproof and breathable membrane is made of expanded polytetrafluoroethylene.

[0014] In one embodiment, the heating frame is a mesh-like hollow structure, and heating resistance wires are threaded through the mesh-like hollow structure.

[0015] In one embodiment, the heating frame is fitted to the moisture-proof and breathable component.

[0016] In one embodiment, the top of the cabinet is further provided with a shock-absorbing connector that connects the cabinet to the top compartment of the mining truck platform, and the shock-absorbing connector is an elastic steel wire rope.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This utility model effectively isolates the vibrations generated during mining operations by setting up a dual shock absorption structure consisting of a bottom shock absorber and an internal shock absorber, preventing damage to internal components or loosening of connections due to long-term vibration. At the same time, the combination of moisture-proof and breathable components, a heating frame, and a temperature and humidity control system ensures effective heat dissipation of the cabinet under high-temperature conditions and can actively heat and introduce air in high-humidity environments to prevent condensation.

[0027] The following will be combined with the appendix Figures 1 to 7 The present invention will be further described below.

[0028] like Figures 1 to 7 As shown, this utility model provides a mining truck on-board control cabinet, including a cabinet body 1, a bottom shock absorber 2 located at the bottom of the cabinet body 1, and a mounting back plate 3 located inside the cabinet body 1. The mounting back plate 3 is connected to the cabinet body 1 through several internal shock absorbers 4, and components 5 are mounted on the mounting back plate 3. The cabinet body 1 is provided with an air inlet 6 and an air outlet 7. Both the air inlet 6 and the air outlet 7 are provided with detachable moisture-proof and breathable components 8. The air inlet 6 is also provided with a heating frame 9 for heating the incoming air. A fan 10 is provided at the air inlet 6 and / or the air outlet 7. Figure 2As shown, in this embodiment, the fan 10 is located at the air outlet 7. The cabinet 1 is equipped with a temperature and humidity control system, which includes a temperature sensor 11, a humidity sensor 12, and a control switch 13. The control switch 13 is electrically connected to the temperature sensor 11, humidity sensor 12, heating frame 9, and fan 10. The control switch 13 has preset temperature and humidity thresholds, used to control the start and stop of the fan 10 based on the comparison between the output signal of the temperature sensor 11 and the temperature threshold, and to control the start and stop of the heating frame 9 and fan 10 based on the comparison between the output signal of the humidity sensor 12 and the humidity threshold. When the temperature sensor 11 detects that the temperature inside the cabinet is higher than the preset temperature threshold, the control switch 13 immediately starts the fan 10 for forced ventilation and heat dissipation; when the humidity sensor 12 detects that the humidity inside the cabinet is higher than the preset humidity threshold, the control switch 13 simultaneously starts the fan 10 and heating frame 9, reducing the relative humidity of the incoming air by heating it, thereby effectively preventing condensation inside the cabinet and achieving active moisture control of the cabinet environment.

[0029] The mining truck-mounted control cabinet provided in this embodiment of the application forms a double shock absorption structure by setting a bottom shock absorber 2 at the bottom of the cabinet body 1 and an internal shock absorber 4 between the mounting back plate 3 and the cabinet body 1. This effectively isolates the vibration generated during mining truck operation and prevents the internal components 5 from being damaged or loosened due to long-term vibration. At the same time, by setting an air inlet 6, an air outlet 7, and a fan 10, and setting moisture-proof and breathable components 8 at the air inlet 6 and the air outlet 7, and setting a heating frame 9 at the air inlet 6 and combining it with a temperature and humidity control system, it not only ensures effective heat dissipation of the cabinet body 1 under high temperature conditions, but also actively heats the air intake and prevents condensation in high humidity environments. This realizes automatic heat dissipation and active moisture control of the vehicle-mounted control cabinet, improving the environmental adaptability and operational reliability of the vehicle-mounted control cabinet under harsh working conditions.

[0030] like Figure 1 and Figure 2 As shown, in some embodiments, the cabinet 1 is provided with a first bracket 14 inside, which divides the inside of the cabinet 1 into a first installation area 15 and a second installation area 16. The first bracket 14 is provided with ventilation holes 14-1. The component 5 includes an electrical module and a controller 5-1. The electrical module is electrically connected to the controller 5-1. The first installation area 15 is used to install the electrical module, and the second installation area 16 is used to install the controller 5-1.

[0031] The cabinet 1 is divided into a first installation area 15 and a second installation area 16 by the first bracket 14, and the electrical modules and controller 5-1 are arranged in separate zones. This structural arrangement not only optimizes the internal space layout of the cabinet and improves the convenience of equipment installation and maintenance, but also effectively avoids mutual interference between the power devices in the electrical modules and the controller 5-1, thereby improving the reliability and electromagnetic compatibility of the system. At the same time, the ventilation holes 14-1 provided on the first bracket 14 ensure that air can flow orderly between the two areas, avoid local stagnation of hot air, and enhance the overall heat dissipation efficiency.

[0032] like Figure 2 As shown, in some embodiments, the mounting backplate 3 includes a first mounting plate 3-1 disposed in a first mounting area 15 and a second mounting plate 3-2 disposed in a second mounting area 16; the bottom of the first mounting plate 3-1 is provided with a plurality of internal shock absorbers 4, and a guide rail 3-1-1 is provided on the first mounting plate 3-1, on which an electrical module and a control switch 13 are mounted. The electrical module includes a power distributor 5-2, a filter 5-3, an air switch 5-4, and a control switch 13.

[0033] By dividing the mounting backplate 3 into two sections—a first mounting plate 3-1 and a second mounting plate 3-2—and installing them respectively in the first mounting area 15 and the second mounting area 16, a structured and modular layout of different functional units is achieved. The internal shock absorber 4 at the bottom of the first mounting plate 3-1 further enhances the shock absorption capacity of this area, protecting the stable operation of the electrical modules. The guide rail 3-1-1 allows for convenient and neat installation and positioning of modular units such as the power distributor 5-2, filter 5-3, air switch 5-4, and control switch 13, improving the efficiency of cabinet assembly and subsequent maintenance, and also facilitating heat dissipation of components 5 and standardized management of wiring harnesses.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, a second bracket 17 is also provided in the second mounting area 16. The two ends of the second mounting plate 3-2 are respectively connected to the first bracket 14 and the second bracket 17 through a plurality of internal shock absorbers 4. A controller 5-1 is provided on the second mounting plate 3-2, and a shock-absorbing pad 18 is provided between the controller 5-1 and the second mounting plate 3-2. There can be multiple controllers 5-1, and the multiple controllers 5-1 are arranged in layers.

[0035] By setting a second bracket 17 within the second mounting area 16 and flexibly connecting the second mounting plate 3-2 between the first bracket 14 and the second bracket 17 via an internal shock absorber 4, further vibration damping is provided for the controller 5-1, while also facilitating heat dissipation for the controller 5-1. Furthermore, the added shock-absorbing pad 18 between the controller 5-1 and the second mounting plate 3-2 further isolates high-frequency micro-vibrations, forming a multi-stage vibration damping structure of bottom shock absorber 2 (cabinet vibration damping) + internal shock absorber 4 (second mounting plate 3-2 vibration damping) + shock-absorbing pad 18 (controller 5-1 vibration damping), providing a more stable working environment for the controller 5-1. By setting up a layered arrangement of multiple controllers 5-1, the space utilization of the second mounting area 16 is improved, and the wiring is made clear and orderly, while also facilitating independent debugging of different controllers 5-1. Figure 2 and Figure 4 As shown, the controller 5-1 has a power interface on one side and a data interface on the other side.

[0036] like Figure 3 As shown, in some embodiments, a power cord insertion port 19 is provided on the side wall of the cabinet 1 corresponding to the first installation area 15, and a data cable insertion port 20 is provided on the side wall of the cabinet 1 corresponding to the second installation area 16; both the power cord insertion port 19 and the data cable insertion port 20 are waterproof interfaces equipped with sealing rings and locking nuts. The side of the controller 5-1 with the data interface faces the direction of the data cable insertion port 20 for easy connection of the data cable.

[0037] By setting power cable entry ports 19 and data cable entry ports 20 in sections on the side wall of cabinet 1, wiring is convenient. By using waterproof interfaces equipped with sealing rings and locking nuts, it can effectively prevent water vapor, dust and other pollutants from entering the cabinet 1 from the cable entry point, thereby improving the overall protection level of cabinet 1 and making it suitable for the harsh working environment of high humidity and dust in mines.

[0038] like Figure 1 and Figure 3 As shown, in some embodiments, the air inlet 6 and the air outlet 7 are provided with louvers 21 that allow downward ventilation, and the air inlet 6 and the air outlet 7 are provided with a shading edge 22 above them.

[0039] By installing downward-facing louvers 21 on the outside of the air inlet 6 and the air outlet 7 and adding a cover 22 above them, rainwater, dust and large foreign objects can be effectively prevented from falling vertically into the cabinet 1. While ensuring smooth airflow and meeting heat dissipation requirements, the outdoor environmental protection level of the cabinet 1 is improved, making it suitable for the harsh working conditions of rainy and dusty mines.

[0040] like Figure 5As shown, in some embodiments, the moisture-proof and breathable component 8 includes an outer frame 8-1 and a waterproof and breathable membrane 8-2 disposed in the middle of the outer frame 8-1. The outer frame 8-1 is typically made of metal or high-strength plastic and is detachably fixed to the air inlet 6 and air outlet 7 of the cabinet 1 by screws, facilitating daily cleaning or replacement. The waterproof and breathable membrane 8-2 is made of expanded polytetrafluoroethylene (PTFE), which has a microporous structure that allows air molecules to pass through smoothly to achieve gas exchange and pressure balance, while effectively blocking the intrusion of liquid water, water vapor, and dust particles. Figure 6 This is a schematic diagram of the assembly structure of the louvers, moisture-proof and breathable components and heating frame at the air inlet. In this embodiment, the moisture-proof and breathable components 8 are located on the outside of the heating frame 9. In other embodiments, the moisture-proof and breathable components 8 can also be located on the inside of the heating frame 9. With this arrangement, when disassembling and assembling the moisture-proof and breathable components 8, it is not necessary to remove the louvers 21 first, making it more convenient to replace the moisture-proof and breathable components 8. Figure 7 A structural diagram of the louvers and heating frame when the moisture-proof and breathable components are removed.

[0041] By employing a moisture-proof and breathable component 8 consisting of an external frame 8-1 and an expanded polytetrafluoroethylene (PTFE) waterproof and breathable membrane 8-2, an efficient airflow channel and a reliable protective barrier are established between the inside and outside of the cabinet 1. This design effectively blocks the intrusion of external liquid water, moisture, and dust particles, preventing short circuits, corrosion, and other malfunctions of the components 5 inside the cabinet 1 caused by condensation or dust accumulation. The waterproof and breathable membrane 8-2 can also be made of other materials with excellent waterproof and breathable properties.

[0042] like Figure 5 As shown, in some embodiments, the heating frame 9 has a mesh-like perforated structure, with heating resistance wires threaded inside. This mesh-like perforated structure is preferably made of a high-temperature resistant and corrosion-resistant metal material (such as stainless steel or aluminum alloy). Its mesh shape not only ensures low ventilation resistance but also provides a uniform installation position for the heating resistance wires, allowing for uniform heating of the air entering the air inlet 6. This facilitates a rapid increase in the temperature of the incoming air, thereby reducing the relative humidity and minimizing condensation inside the cabinet 1.

[0043] like Figure 6 As shown, in some embodiments, the heating frame 9 is fitted to the moisture-proof and breathable component 8. This arrangement allows the heat generated by the heating frame 9 to act directly and efficiently on the moisture-proof and breathable component 8, quickly evaporating and driving away any trace amounts of water vapor or moisture that may condense on its surface. This effectively prevents the moisture-proof and breathable component 8 from losing its breathability due to the intake of a large amount of humid air, and maintains the long-term unobstructed airflow path.

[0044] like Figure 3As shown, in some embodiments, the top of the cabinet 1 is also provided with a shock-absorbing connector 23 that connects the cabinet 1 to the top compartment of the mining truck platform. The shock-absorbing connector 23 is an elastic steel wire rope, and its two ends are reliably connected to the preset connection point on the top of the cabinet 1 and the corresponding anchor point on the top compartment of the mining truck platform through high-strength shackles or universal connectors, respectively, to form a flexible suspension fixation. By adding a shock-absorbing connector 23 to the top of the cabinet 1, the top sway of the cabinet 1 can be suppressed, and together with the bottom shock absorber 2, it forms a multi-point, multi-directional shock absorption and fixation system, which is beneficial to the overall shock absorption of the cabinet 1.

[0045] Specifically, such as Figure 1 and Figure 3 As shown, the cabinet 1 also includes an openable cabinet door 1-1 located at the top of the cabinet 1. The cabinet door 1-1 is equipped with a handle 1-1-1 and a lifting lug 1-1-2. One end of the elastic steel wire rope is connected to the lifting lug 1-1-2, and the other end is connected to the top compartment of the mining truck platform. The cabinet 1 is equipped with a latch 1-2 for locking the cabinet door 1-1 and a power switch 24 for controlling the power supply of the electrical module. The cabinet door 1-1 is equipped with a sealing strip 25, and a sealing protrusion 26 is provided on the cabinet 1 at the position corresponding to the sealing strip 25, so as to facilitate the overall sealing and dust and moisture prevention of the cabinet 1. The bottom of the bottom shock absorber 2 is connected to a connecting plate 27 for fixing and connecting the mining truck platform, which facilitates the fixed installation of the cabinet 1.

[0046] In summary, this utility model effectively isolates the vibrations generated during mining operations by setting up a dual shock absorption structure consisting of a bottom shock absorber 2 and an internal shock absorber 4, preventing damage or loosening of the internal components 5 due to long-term vibration. At the same time, the combination of a moisture-proof and breathable component 8, a heating frame 9, and a temperature and humidity control system ensures effective heat dissipation of the cabinet 1 under high-temperature conditions, and also enables active heating and air intake to prevent condensation in high-humidity environments. This achieves automatic heat dissipation, reduces relative humidity, and seals the vehicle-mounted control cabinet against moisture, improving its environmental adaptability and operational reliability under harsh working conditions.

[0047] Components and principles not described in detail in this utility model can be implemented using various structures and principles known in the prior art.

[0048] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
