Description

Technical Field

[0001] This utility model relates to the technical field of power control equipment for mining vehicles, specifically a power switching controller for mining vehicles that is easy to maintain. Background Technology

[0002] In the mining operation environment, mining vehicles need to frequently switch between different power modes, such as starting power, working power, and emergency power, to ensure that the vehicles can operate normally under various working conditions. As one of the core components of the electrical system of mining vehicles, the power switching controller is responsible for realizing automatic power switching and stable control.

[0003] However, existing power switching controllers for mining vehicles still have certain problems in use: Existing power switching controllers are mostly installed using fixed bolt connections, which are cumbersome to install and disassemble. When the controller malfunctions or requires regular maintenance, it consumes a lot of time and manpower, affecting the efficiency of mining operations. At the same time, their heat dissipation and dust protection designs are often difficult to balance. Poor heat dissipation can easily lead to damage to internal components due to high temperatures, while insufficient dust protection can allow dust to enter and cause short circuits and other malfunctions, shortening the lifespan of the controller and increasing the cost of use. Therefore, we propose a power switching controller for mining vehicles that is easy to maintain, in order to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a power switching controller for mining vehicles that is easy to maintain, in order to solve the problems mentioned in the background art. The power switching controllers are mostly installed by fixed bolt connections, which are cumbersome to install and disassemble. When the controller malfunctions or requires regular maintenance, a lot of time and manpower are consumed, affecting the efficiency of mining operations. At the same time, it is often difficult to balance heat dissipation and dust prevention. Poor heat dissipation can easily lead to damage to internal components due to high temperature, and insufficient dust prevention can cause dust to enter and cause short circuits and other faults, shortening the service life of the controller and increasing the cost of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power switching controller for mining vehicles that is easy to maintain, comprising a housing and a maintenance door. The maintenance door is rotatably connected to the outer side of the housing via a hinge. A mounting block is fixed to the rear end face of the housing. The mounting block has symmetrical slots on both sides. A mounting seat is provided at the rear of the housing. The mounting seat has mounting holes at its four corners. The outer surface of the mounting seat has mounting grooves that fit the mounting block. The interior of the mounting seat has symmetrical sliding grooves. Adjusting screws are threadedly connected to both sides of the mounting seat. The end of the adjusting screw is bearing-connected to a locking block that fits the slot, and the locking block and the sliding groove are in a close sliding connection. A fastening nut is threadedly connected to the outer surface of the adjusting screw and located on the outer side of the mounting seat.

[0006] By adopting the above technical solution, the mounting block at the rear end of the housing is embedded into the mounting groove of the mounting base, the adjusting screw is rotated to move the locking block along the slide and into the locking groove, and the adjusting screw is then fixed with a fastening nut, so as to achieve a stable installation of the housing of the power switching controller for mining vehicles and the mounting base, and facilitate disassembly and maintenance.

[0007] Preferably, a plurality of heat dissipation holes are symmetrically provided on both sides of the outer shell, and an installation frame is bolted to the inner side of the outer shell at the corresponding heat dissipation holes, and a dustproof mesh is embedded in the middle of the installation frame.

[0008] The above technical solution involves opening heat dissipation holes on both sides of the outer casing to facilitate the dissipation of internal heat. Dustproof mesh is inlaid in the corresponding heat dissipation holes on the inner side through the mounting frame. While ensuring effective heat dissipation of the controller, the dustproof mesh prevents dust from entering the inner casing and protects the internal components.

[0009] Preferably, the heat dissipation holes are rectangular in design, and several heat dissipation holes are arranged longitudinally along the side of the outer casing.

[0010] Using the above technical solution, the rectangular heat dissipation holes are easy to process and form, and the longitudinal arrangement can increase the number and coverage of heat dissipation holes, increase the contact area between the outer shell and the outside air, improve air circulation efficiency, and thus more effectively dissipate the heat inside the controller.

[0011] Preferably, the outer shell has an inner shell inside, and springs are bolted to the four corners of the inner shell. The other end of the spring is fixedly connected to the inner wall of the outer shell by bolts, and a damper is installed in the middle of the spring.

[0012] By adopting the above technical solution, the elastic deformation characteristics of the spring are utilized, and the damper is used to consume the vibration energy of the spring. When the outer shell is vibrated, the spring buffers part of the impact force, and the damper suppresses the continuous vibration of the spring. This effectively reduces the impact of external vibration on the electronic components in the inner shell, reduces the risk of component damage caused by vibration, and improves the stability and reliability of the power switching controller for mining vehicles.

[0013] Preferably, the upper and lower ends of the outer shell are symmetrically provided with first screw holes, the upper and lower ends of the inspection door are symmetrically welded with mounting plates, the outer surface of the mounting plate is provided with second screw holes that are adapted to the first screw holes, and fastening bolts are threadedly connected to the middle of the first screw holes and the second screw holes.

[0014] By adopting the above technical solution, a first screw hole is provided on the outer shell, and a mounting plate with a second screw hole is welded on the inspection door. The connection between the outer shell and the inspection door is achieved by using the threaded engagement of the fastening bolts with the first and second screw holes. This allows the inspection door to be securely installed on the outer shell, while also making it easy to open the inspection door by removing the fastening bolts, facilitating maintenance and repair of the controller's internal components.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The mounting holes at the four corners of the mounting base facilitate secure installation on mining vehicles; the rear mounting block of the outer shell fits into the mounting groove of the mounting base for quick positioning, and the adjusting screw drives the locking block to move along the slide groove and engage with the mounting block's locking groove. The tightening nut prevents loosening, achieving a secure and convenient connection between the outer shell and the mounting base, and facilitating subsequent disassembly; the inspection door is connected to the outer shell via a hinge for easy opening and closing, facilitating maintenance and repair of the controller's internal components, improving the ease of installation and maintenance efficiency, and enhancing its applicability in complex mining environments; 2. Several rectangular, longitudinally arranged heat dissipation holes are symmetrically opened on both sides of the outer casing. The rectangular design facilitates processing and forming, while the longitudinal arrangement increases the heat dissipation area and airflow range, effectively promoting heat exchange between the inside of the casing and the outside air. This quickly dissipates the heat generated by the internal electronic components, preventing excessive temperature from affecting component performance and lifespan. At the same time, the dustproof mesh embedded in the mounting frame connected by bolts to the corresponding heat dissipation holes on the inside effectively prevents external dust from entering the casing through the heat dissipation holes, preventing dust accumulation on the component surface and causing short circuits and other malfunctions. While ensuring good heat dissipation, it also plays a good role in dust protection, improving the stability and reliability of the controller in the dusty environment of the mine.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1-6 This utility model provides a technical solution: a power switching controller for mining vehicles that is easy to maintain, including a housing 1 and an inspection door 2. The inspection door 2 is rotatably connected to the outer side of the housing 1 via a hinge. A mounting block 3 is fixed to the rear end face of the housing 1. The mounting block 3 has symmetrical slots 4 on both sides. A mounting seat 5 is provided at the rear of the housing 1. The mounting seat 5 has mounting holes 6 at its four corners. The outer surface of the mounting seat 5 has mounting grooves 7 that are adapted to the mounting block 3. The interior of the mounting seat 5 has symmetrical sliding grooves 8. Adjusting screws 9 are threaded through and connected to both sides of the mounting seat 5. The end of the adjusting screw 9 is connected to a bearing with a locking block 10 that is adapted to the slot 4. The locking block 10 and the sliding groove 8 are in close sliding connection. A fastening nut 11 is threadedly connected to the outer surface of the adjusting screw 9 and located on the outer side of the mounting seat 5.

[0020] The mounting block 3 fixed at the rear end of the outer shell 1 is used to connect with the mounting base 5. The mounting groove 7 on the mounting base 5 is adapted to the mounting block 3, which can initially position the outer shell 1. The adjusting screw 9 is threaded through both sides of the mounting base 5. When the adjusting screw 9 is rotated, the end bearing is connected to the locking block 10, which slides in contact with the slide groove 8 and is adapted to the locking groove 4. The locking block 10 will move along the slide groove 8 and lock into the locking groove 4, realizing a stable connection between the outer shell 1 and the mounting base 5. After that, tightening the fastening nut 11 on the outside of the adjusting screw 9 can prevent the adjusting screw 9 from loosening. The mounting holes 6 at the four corners of the mounting base 5 make it easy to fix it on the mining vehicle, which not only facilitates the installation of the controller on the vehicle, but also facilitates the subsequent disassembly of the outer shell 1 for maintenance and repair, thus improving convenience.

[0021] Several heat dissipation holes 12 are symmetrically provided on both sides of the outer casing 1. A mounting frame 13 is bolted to the inner side of the outer casing 1 at the corresponding heat dissipation holes 12. A dustproof mesh 14 is embedded in the middle of the mounting frame 13. The heat dissipation holes 12 are rectangular in design, and several heat dissipation holes 12 are arranged longitudinally along the side of the outer casing 1.

[0022] Several rectangular heat dissipation holes 12 are symmetrically opened on both sides of the outer casing 1 and are arranged longitudinally along the side ends. The rectangular design facilitates processing and manufacturing, and the longitudinal arrangement increases the number and coverage of the heat dissipation holes 12, which is conducive to heat exchange between the inside of the outer casing 1 and the outside air, so that the internal heat can be quickly dissipated. At the same time, the mounting frame 13 is bolted to the inner side of the outer casing 1 at the corresponding heat dissipation holes 12, and a dustproof net 14 is embedded in the middle of the mounting frame 13. The dustproof net 14 can effectively block the external dust from entering the inside of the outer casing 1 through the heat dissipation holes 12, and prevent dust accumulation from affecting the performance and life of the electronic components inside the controller. Thus, it plays a role in dust protection while ensuring good heat dissipation.

[0023] The outer shell 1 has an inner shell 15 inside, and springs 16 are bolted to the four corners of the inner shell 15. The other end of the springs 16 is fixedly connected to the inner wall of the outer shell 1 by bolts. A damper 17 is installed in the middle of the springs 16.

[0024] An inner shell 15 is installed inside the outer shell 1. Springs 16 are connected to the four corners of the inner shell 15 by bolts. The other end of the springs 16 is also fixed to the inner wall of the outer shell 1 by bolts. A damper 17 is installed in the middle of the springs 16. When the controller is subjected to external vibration, the springs 16 will undergo elastic deformation due to the vibration, using their elasticity to buffer part of the vibration energy and reduce the direct impact of the vibration on the electronic components in the inner shell 15. The damper 17 can consume the energy of the springs 16 during the vibration process, suppress the continuous vibration of the springs 16, and prevent the inner shell 15 from shaking for a long time, thereby effectively protecting the internal electronic components and improving the stability and reliability of the controller in the complex vibration environment of the mine.

[0025] The upper and lower ends of the outer casing 1 are symmetrically provided with first screw holes 18, and the upper and lower ends of the inspection door 2 are symmetrically welded with mounting plates 19. The outer surface of the mounting plate 19 is provided with second screw holes 20 that are compatible with the first screw holes 18. Fastening bolts 21 are threadedly connected to the middle of the first screw holes 18 and the second screw holes 20.

[0026] The outer casing 1 has symmetrical first screw holes 18 at its upper and lower ends. The inspection door 2 has mounting plates 19 with second screw holes 20 that are adapted to the first screw holes 18 welded symmetrically at its upper and lower ends. By simultaneously screwing the fastening bolts 21 into the first screw holes 18 and the second screw holes 20, the inspection door 2 can be firmly fixed to the outer casing 1 using the tightness of the threaded connection, preventing the inspection door 2 from being opened accidentally and protecting the internal components. When maintenance and repair of the controller is required, the inspection door 2 can be easily opened by simply unscrewing the fastening bolts 21. The operation is convenient and quick, greatly improving maintenance efficiency.

[0027] Working principle: For this type of easy-to-maintain power switching controller for mining vehicles, during installation, it is fixed to the mining vehicle through the mounting holes 6 at the four corners of the mounting base 5. The mounting block 3 at the rear end of the outer shell 1 is initially positioned by inserting it into the mounting groove 7 of the mounting base 5. The adjusting screws 9 on both sides of the mounting base 5 are rotated so that the locking block 10 connected to the end bearing moves along the slide groove 8 and locks into the locking grooves 4 on both sides of the mounting block 3. Then, the fastening nut 11 on the outside of the adjusting screw 9 is tightened to prevent loosening. During use, the rectangular heat dissipation holes 12 arranged longitudinally on both sides of the outer shell 1 facilitate heat exchange and heat dissipation between the inside and the outside. The dustproof net 14 on the inner mounting frame 13 prevents dust from entering. When subjected to external vibration, the spring 16 connected between the inner wall of the outer shell 1 and the four corners of the inner shell 15 elastically deforms to buffer the vibration. The damper 17 in the middle of the spring 16 consumes vibration energy and suppresses continuous shaking. During maintenance, the fastening bolt 21 connecting the first screw hole 18 at the upper and lower ends of the outer shell 1 and the second screw hole 20 on the mounting plate 19 of the inspection door 2 can be unscrewed to open the inspection door 2.
