Description

Technical Field

[0001] This invention relates to the field of mining electric dump truck technology, and in particular to a battery anti-collision and shock absorption installation structure for mining electric dump trucks. Background Technology

[0002] Mining electric dump trucks are mainly used in harsh working conditions such as open-pit mines, tunnel excavation, and large-scale water conservancy projects. The vehicles need to frequently travel on rugged and uneven slopes and bear the huge load brought by heavy transportation. As the core power source of electric dump trucks, the battery is large and heavy, and is usually installed at the front or bottom of the frame. When the vehicle is traveling at high speed or encounters road bumps, the vehicle body will experience severe bumps and twists. At the same time, the mining working environment is complex, and the vehicle is very prone to collision accidents.

[0003] Existing battery mounting structures typically use rigid connections or simple rubber shock-absorbing pads for fixation. Rigid connections cannot effectively attenuate the impact energy transmitted from the road surface, causing the battery casing to bear stress directly, which can easily lead to breakage of the internal cell tabs or damage to the separator. Although simple rubber shock-absorbing pads can filter some high-frequency micro-vibrations, their buffering stroke is limited when facing severe bumps or lateral impacts with a large stroke, and they cannot limit the excessive displacement of the battery pack.

The surface of the adjusting worm gear 12 is rotatably connected to the inner wall of the dustproof box 10. The surface of the dustproof box 10 is fixedly connected to the lower end of the bearing plate 303. Driven worm gear 11 is disposed on the inner wall of dustproof box 10, and the tooth surface of adjusting worm 12 is meshed with the tooth surface of driven worm gear 11. The inner wall of driven worm gear 11 is fixedly connected to the lower end of driving screw 9. Specifically, the protective box 301 is equipped with guide rails 404 at both ends, and guide seats 406 are slidably connected to the surface of the guide rails 404. The inner wall of the guide seat 406 slides on the surface of the guide rod 401 through the stroke sleeve 408. Springs 402 are sleeved on both ends of the guide rod 401, and bearing seats 407 are fixed to the inner wall of the guide seat 406. The same mechanical structure is also arranged between the mounting box 305 and the bearing plate 303. These two parts are connected by a connecting rod 405. When the protective box 301 is vibrated, the protective box 301 will shift to both ends, and the displacement of the protective box 301 will indirectly compress the connection. The guide seat 406 at the lower end of the rod 405 slides on the surfaces of the guide rod 401 and the guide rail 404. This sliding process can disperse the energy generated by vibration. When the guide seat 406 slides on the surface of the guide rod 401, the spring 402 generates an elastic force. The elastic force of the spring 402 causes the guide seat 406 to automatically reset. The reset action of the spring 402 and the buffering action of the hydraulic rod 304 work together to achieve the vibration reduction purpose of the system. The entire system provides comprehensive protection for the battery of the mining electric dump truck through multi-layer protection, hydraulic buffering, spring 402 reset and heat dissipation management. In specific application scenarios, the problem of battery susceptibility to impact and vibration damage under harsh working conditions is solved. A multi-layered nested structure absorbs external impact energy. The hydraulic rod 304 provides flexible support inside the mounting box 305, allowing the support plate 303 to displace the battery when shaken. This displacement effectively mitigates damage to the battery body from hard impacts. The shock-absorbing pads 302 on both sides of the protective box 301 further absorb high-frequency vibrations. The guide seat 406, together with the guide rod 401 and spring 402, forms a reset and shock-absorbing unit. Vibration energy is transmitted to the guide seat 406 through the connecting rod 405. The guide seat 406 slides on the surface of the guide rail 404 and compresses the spring 402. The elastic force generated by the spring 402 causes the mechanism to automatically reset. The radiator 30... 6. The temperature of the battery's working environment is kept stable. The servo motor 7 drives the limit block 5 to lock the protective box 301. This locking method ensures that the battery is fixed in position during transportation. Compared with the existing technology, it adopts a design that combines multi-level linkage shock absorption and active locking. The existing technology usually only relies on a single rubber pad or a simple spring 402 for buffering. This device achieves multi-dimensional vibration filtering through the cooperation of hydraulic rod 304, shock absorption pad 302 and spring 402 guide mechanism. The cooperation of worm gear and servo motor 7 realizes the automated installation and locking of the battery, improving installation efficiency and connection reliability. The multi-layer protective box 301 body structure improves the impact resistance of the battery pack, effectively extends the battery's service life and ensures the safe operation of the mine car 1.

[0022] Reference Figure 5 and Figure 7 In a preferred embodiment, the damping mechanism 4 includes: Guide seat 406 is disposed on the surface of guide rail 404. The inner wall of guide seat 406 is slidably connected to the surface of guide rail 404. Multiple guide rails 404 are respectively fixedly connected to the inner wall of bearing plate 303 and placement box 305. The multiple guide rails 404 are arranged in parallel and collinear. The surface of guide seat 406 is slidably connected to the surface of bearing plate 303 and placement box 305. Bearing housing 407 is disposed on the surface of guide seat 406, and the surface of bearing housing 407 is fixedly connected to the surface of guide seat 406; A connecting rod 405 is disposed between the mounting box 305 and the bearing plate 303. The two connecting rods 405 are rotatably connected by a rotating shaft. Both ends of the inner wall of the connecting rod 405 are rotatably connected to the surface of the bearing seat 407. A guide rod 401 is disposed between two guide rails 404, and both ends of the guide rod 401 are fixedly connected to the bearing plate 303 and the inner wall of the mounting box 305, respectively; The travel sleeve 408 is sleeved on both ends of the guide rod 401. The inner wall of the travel sleeve 408 is slidably connected to the surface of the guide rod 401, and the surface of the travel sleeve 408 is fixedly connected to the inner wall of the guide seat 406. Spring 402, two springs 402 are sleeved on both ends of guide rod 401, and both ends of spring 402 are fixedly connected to the surface of guide rod 401 and stroke sleeve 408 respectively; Telescopic sleeve 403 is disposed on the outside of guide rod 401. Both ends of telescopic sleeve 403 are fixedly connected to the surfaces of two guide seats 406, and guide rod 401 and spring 402 are both accommodated inside telescopic sleeve 403. Specifically, the protective box 301 is equipped with guide rails 404 at both ends. Guide seats 406 are slidably connected to the surface of the guide rails 404. The inner wall of the guide seat 406 slides on the surface of the guide rod 401 through the stroke sleeve 408. Springs 402 are sleeved on both ends of the guide rod 401. Bearing seats 407 are fixed to the inner wall of the guide seat 406. The same mechanical structure is also arranged between the mounting box 305 and the bearing plate 303. These two parts are connected by the connecting rod 405. When the protective box 301 is vibrated, the protective box 301 will shift to both ends. The displacement of the protective box 301 will indirectly squeeze... The connecting rod 405 is pressed, and the guide seat 406 at the lower end of the connecting rod 405 slides on the surface of the guide rod 401 and the guide rail 404. This sliding process can disperse the energy generated by vibration. When the guide seat 406 slides on the surface of the guide rod 401, the spring 402 will generate elastic force. The elastic force of the spring 402 will cause the guide seat 406 to automatically reset. The reset action of the spring 402 and the buffering action of the hydraulic rod 304 work together to achieve the purpose of shock absorption. Through multi-layer protection, hydraulic buffering, spring 402 reset and heat dissipation management, comprehensive protection is provided for the battery of the mining electric dump truck. In specific application scenarios, it is mainly used to solve the displacement and vibration problems caused by severe vehicle bumps. When the protective box 301 is vibrated and displaced, the protective box 301 will push the support plate 303 to move. The movement of the support plate 303 will squeeze the connecting rod 405. After the connecting rod 405 is subjected to force, it will drive the guide seat 406 to slide on the guide rail 404 and the guide rod 401. The sliding process of the guide seat 406 consumes the energy generated by the vibration. The spring 402 is compressed or stretched when the guide seat 406 slides. The elastic reaction force generated by the spring 402 causes the guide seat 406 to reset. The reset of the guide seat 406 drives the connecting rod 405 and the support plate 303 back to the initial position. This structure converts vibration energy into mechanical motion and dissipates it. The damping mechanism 4 and the hydraulic The pressure rod 304 works in concert, with the hydraulic rod 304 providing the main buffer stroke and the spring 402 mechanism providing the restoring force and assisting in dispersing high-frequency vibrations. This mechanism effectively prevents the battery pack from undergoing rigid collisions under severe vibrations. Compared to existing technologies, this design uses a combination of connecting rod guidance and spring 402 restoring, whereas existing technologies typically rely solely on a single hydraulic damping or rubber component for buffering. Through the cooperation of the connecting rod 405 and the guide seat 406, the movement trajectory of the battery pack is restricted, preventing disorderly shaking of the battery pack during vibrations. The spring 402, sleeved on the guide rod 401, provides a stable restoring force, and the telescopic sleeve 403 protects the internal components from mine dust contamination. This mechanism, in conjunction with the hydraulic system, achieves more efficient energy dissipation and improves the stability of the battery pack under complex road conditions.

[0023] Working Principle: For the anti-collision buffer protection of the battery of the mining electric dump truck, the operator first puts the battery into the protective box 301. Then, the operator rotates the adjusting worm gear 12 on the bearing plates 303 on both sides of the protective box 301. The rotation of the adjusting worm gear 12 will drive the driven worm wheel 11 at the lower end of the driving screw 9 to rotate. The driving screw 9 is connected to the transmission plate 8 through a threaded engagement. When the adjusting worm gear 12 rotates, the transmission plate 8 will move on its surface. The upper end of the transmission plate 8 is connected to the limiting block 5 through the support rod 6. The movement of the transmission plate 8 will drive the limiting block 5 to move to the groove on the surface of the protective box 301. Subsequently, the servo motor 7 drives the limiting block 5 to rotate around the pivot at the upper end of the support rod 6. The limiting block 5 will then insert into the protective box 301. Inside the protective box 301, as the operator continues to rotate the adjusting worm gear 12, the adjusting worm gear 12 will pull the limiting block 5 to move continuously. Limiting blocks 5 are provided at both ends of the protective box 301. The limiting blocks 5 pull the protective box 301 towards both ends, ensuring a stable connection between the protective box 301 and the support plate 303. After completing the above steps, the operator places the protective box 301 in the center of the placement box 305, which is then placed inside the impact box 2. This multi-layered nested structure effectively reduces the damage to the battery caused by impacts. A hydraulic rod 304 connects the protective box 301 and the placement box 305, providing necessary support. When the battery is subjected to external shaking, the hydraulic rod 304 allows the protective box 301 to move the battery within a certain range. Within a certain range, this movement mechanism can mitigate the impact of vibration on the battery. Shock-absorbing pads 302 are also provided on both sides of the protective box 301, further reducing the impact of vibration on internal components. Heat sinks 306 are equipped on both sides of the mounting box 305, responsible for maintaining a stable internal temperature to ensure continuous battery operation. Guide rails 404 are also provided at both ends of the protective box 301, with guide seats 406 slidably connected to their surfaces. The inner wall of the guide seat 406 slides on the surface of the guide rod 401 via a travel sleeve 408. Springs 402 are fitted at both ends of the guide rod 401, and bearing seats 407 are fixed to the inner wall of the guide seat 406. The same mechanical structure is also arranged in the mounting box 305. Between the protective box 301 and the bearing plate 303, these two structural parts are connected by a connecting rod 405. When the protective box 301 is vibrated, it will shift to both ends. The displacement of the protective box 301 will indirectly compress the connecting rod 405. The guide seat 406 at the lower end of the connecting rod 405 will slide on the surface of the guide rod 401 and the guide rail 404. This sliding process can disperse the energy generated by the vibration. When the guide seat 406 slides on the surface of the guide rod 401, the spring 402 will generate an elastic force. The elastic force of the spring 402 will cause the guide seat 406 to automatically reset. The reset action of the spring 402 and the buffering action of the hydraulic rod 304 work together to achieve the purpose of shock absorption. Through multi-layer protection, hydraulic buffering, spring 402 reset, and heat dissipation management,It provides comprehensive protection for the batteries of mining electric dump trucks.
