[0019] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0020] Combined with Figure 1 -Attached Figure 3 , a protection device for unmanned transportation of mining electric locomotives, including a mounting crossbeam 1, energy absorption boxes 2 are provided at both ends of the mounting crossbeam 1, a mounting plate 3 connected to the end plate of the mining electric locomotive is provided at the rear end of the energy absorption box 2, a buffer column 4 capable of moving forward and backward is provided at the front end of the energy absorption box 2, a bow beam 5 is provided at the front end of the buffer column 4, a protective buffer pad 6 is provided at the front end of the bow beam 5, a buffer groove 7 is relatively provided at the front end of the mounting crossbeam 1, a buffer block 8 is provided in the buffer groove 7 for sliding, and a first buffer spring 9 is connected between the buffer block 8 and the inner wall of the buffer groove 7, and adjustment arms 10 are hinged on both sides of the buffer blocks 8, and a mounting block 11 is provided at the rear end of the bow beam 5, and the ends of the adjustment arms 10 on both sides away from the buffer block 8 are respectively hinged to the two sides of the mounting block 11. The core of the protection device lies in its multi-stage buffering and energy absorption mechanism, which is intended to minimize the damage to the mining electric locomotive and its unmanned driving system caused by collision. When the mining electric locomotive encounters an obstacle or collides in the unmanned driving state, it will first touch the protective buffer pad 6 at the front end of the bow beam 5. As the first-level buffer layer, the protective buffer pad 6 uses its high elasticity and wear resistance to quickly absorb and slow down the initial impact force generated by the collision, effectively preventing the direct damage of the rigid collision to the electric locomotive and the surrounding environment. As the collision force is further transmitted, the compression of the protective buffer pad 6 will drive the arched beam 5 to drive the adjustment arm 10 on the rear end mounting block 11, and transmit the impact force to the buffer block 8 in the buffer groove 7 at the front end of the mounting beam 1. The hinged design of the adjustment arm 10 allows it to rotate flexibly when impacted, thereby guiding and dispersing the impact force and ensuring uniform distribution of force. At this time, the buffer block 8 will slide and compress along the trajectory of the buffer groove 7 under the elastic force of the first buffer spring 9. During the compression process of the first buffer spring 9, its elastic potential energy gradually accumulates, thereby further absorbing and dispersing the collision energy. At the same time, the sliding of the buffer block 8 also increases the buffering stroke, prolongs the buffering time, and makes the release of the collision energy more gentle.
[0021] Finally, when the collision force is transmitted to the energy absorbing box 2 at both ends of the mounting crossbeam 1, the special structure inside the energy absorbing box 2 will start to work, and through the plastic deformation of the material or other energy absorption mechanisms, the remaining collision energy will be converted into heat energy or other forms of energy dissipation. In this process, the energy absorbing box 2 not only absorbs the collision energy, but also protects the end plate of the electric locomotive and its internal structure from the direct impact of the impact force.
[0022] In one embodiment, the front end of the energy absorption box 2 is provided with a sliding cavity 12 and a through hole 13 located at the front end of the sliding cavity 12, and the inner end of the buffer column 4 is provided with a buffer plate 14 that slides with the sliding cavity 12, and the buffer plate 14 is connected to the inner end of the sliding cavity 12 with a second buffer spring 15. In this embodiment, the energy absorption box 2 is a key component for energy absorption, and its front end is designed with a sliding cavity 12 and a through hole 13 located at the front end of the sliding cavity. The inner end of the buffer column 4 is provided with a buffer plate 14 that slides closely with the sliding cavity 12. When a collision occurs, the buffer plate 14 slides backward in the sliding cavity 12 and compresses the second buffer spring 15 at the same time, effectively absorbing and dispersing the energy generated by the collision. This multi-stage buffer structure design, that is, the initial buffering of the arched beam 5 and the protective buffer pad 6, and the further buffering of the buffer column 4 and the buffer plate 14 and the second buffer spring 15 in the sliding cavity 12, significantly improves the overall impact resistance of the protective device.
[0023] In one embodiment, a connecting plate 16 is provided on the buffer column 4, a first T-shaped mounting column 17 is provided at the rear end of the connecting plate 16, a second T-shaped mounting column 18 corresponding to the position of the first T-shaped mounting column 17 is provided at the front end of the energy absorption box 2, and a third buffer spring 19 is connected between the first T-shaped mounting column 17 and the second T-shaped mounting column 18. In this embodiment, a connecting plate 16 is additionally provided on the buffer column 4, on which the first T-shaped mounting column 17 is provided. Correspondingly, a second T-shaped mounting column 18 precisely corresponding to the position of the first T-shaped mounting column 17 is provided at the front end of the energy absorption box 2. The first T-shaped mounting column 17 and the second T-shaped mounting column 18 are tightly connected by the third buffer spring 19. This design not only enhances the connection stability between the buffer column 4 and the energy absorption box 2, but also provides an additional buffering effect for the entire protective device through the elastic action of the third buffer spring 19, further improving the safety under complex working conditions.
[0024] In one embodiment, the rear end of the mounting block 11 is provided with a third T-shaped mounting column 20, the front end of the mounting cross beam 1 is provided with a fourth T-shaped mounting column 21 corresponding to the position of the third T-shaped mounting column 20, and a fourth buffer spring 22 is connected between the third T-shaped mounting column 20 and the fourth T-shaped mounting column 21. The mounting block 11 is an important connecting component between the arched beam 5 and the mounting cross beam 1, and a third T-shaped mounting column 20 is added to the rear end thereof. The front end of the mounting cross beam 1 is provided with a fourth T-shaped mounting column 21 that precisely corresponds to the third T-shaped mounting column 20, and the two are connected by a fourth buffer spring 22. This design optimizes the dynamic balance performance of the arched beam 5 when it is impacted, and at the same time, the fourth buffer spring 22 provides reliable elastic support for the arched beam, ensuring that the arched beam can maintain a stable posture even in extreme collision conditions, effectively protecting the front end of the electric locomotive from damage.
[0025] In one embodiment, a sliding column 23 is provided in the buffer groove 7, and the buffer block 8 is slidably mounted on the sliding column 23. In order to further improve the sliding stability of the buffer block 8 in the buffer groove 7, the present embodiment adds a sliding column 23 in the buffer groove 7. The buffer block 8 is slidably mounted on the sliding column 23. This design limits the displacement of the buffer block 8 during the sliding process, ensuring that it can slide along a predetermined trajectory when impacted, thereby improving the response speed and stability of the entire protective device.
[0026] In one embodiment, a mounting hole is provided on the mounting plate 3 and a fixing bolt is provided in the mounting hole. In order to further improve the sliding stability of the buffer block 8 in the buffer groove 7, a sliding column 23 is added in the buffer groove 7 in this embodiment. The buffer block 8 is slidably sleeved on the sliding column 23. This design limits the displacement of the buffer block 8 during the sliding process, ensuring that it can slide along a predetermined track when impacted, thereby improving the response speed and stability of the entire protection device.
[0027] Working principle: The protection device for unmanned transportation of mining electric locomotives in this application effectively absorbs collision energy by installing energy absorption boxes and front sliding buffer columns at both ends of the beam. The arched beam at the front end of the buffer column and the protective buffer pad constitute the first buffer layer to reduce direct impact. In the buffer groove at the front end of the mounting beam, the buffer block slides freely under the action of the first buffer spring, and is connected to the mounting block at the rear end of the arched beam through the adjusting arm to form a dynamic balance structure to further disperse the impact force. The buffer plate and the second buffer spring in the sliding cavity, as well as the setting of the connecting plate and the third buffer spring, increase the multi-stage buffering effect. At the same time, the mounting block and the mounting beam are connected by the third T-shaped mounting column, the fourth T-shaped mounting column and the fourth buffer spring to ensure that the structure is stable and has elastic buffering capacity. The cooperation between the sliding column and the buffer block improves the sliding stability, and the fixing bolts on the mounting plate ensure the firm connection between the device and the electric locomotive. The overall design realizes efficient energy absorption and multiple buffering protection.
[0028] The above describes the utility model and its implementation methods, which are not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
