Description
Technical Field
[0001] This utility model relates to the field of search and rescue device technology, and in particular to an intelligent search and rescue device for harsh environments based on radio frequency technology. Background Technology
[0002] In disaster area search and rescue operations, radio frequency (RF) technology is used to transmit RF signals in the disaster environment, and the feedback signals are used for location positioning to determine the location of those being searched for and to carry out rescue operations. Using intelligent search and rescue equipment with RF technology can greatly improve search and rescue efficiency. Traditional search and rescue devices use a single mode of transportation, such as tracked vehicles or ordinary multi-wheeled vehicles. These types of vehicles can generally only adapt to one type of geographical environment. For example, vehicles with tires can only operate normally in dry environments. If they encounter rainy weather or muddy roads, the vehicles are prone to slipping and cannot operate normally. Tracked vehicles, on the other hand, can operate in more complex environments, such as dry ground and muddy roads, but their speed is slow, and they may miss the best opportunity for search and rescue.
[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0026] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example
[0027] A radio frequency technology-based intelligent search and rescue device for harsh environments includes a device body 1. End blocks 2 are integrally formed at both ends of the device body 1. Output shafts 9 are provided on both sides inside the device body 1, with both ends of the output shafts 9 penetrating to the outer sides of the corresponding end blocks 2. Movable grooves 3 are formed on the surface of the end blocks 2. Two vertically distributed locking arms 4 are movably installed in the inner cavity of the movable grooves 3. Supports 5 are provided on both sides of the device body 1. Drive shafts 6 are penetrated on both sides of the top of one side of each support 5. End caps 7, adapted to the output shafts 9, are rotatably mounted on the surface of the drive shafts 6. Pins 8, adapted to the locking arms 4, are fixedly connected to the top and bottom of one side of the end caps 7. One end of the pin 8 penetrates into the interior of the movable groove 3. A fastening bolt 13 is provided through the top of the upper locking arm 4, with the bottom end of the fastening bolt 13 penetrating into the interior of the pin 8.
[0028] The specific usage process is as follows: Select the appropriate driving mode according to the actual working environment. In muddy and potholed search and rescue environments, the user switches the search and rescue device to tracked mode. The specific switching process is as follows: First, loosen and remove all the fastening bolts 13 from the vehicle. Then, flip the two locking arms 4 on the end block 2 upwards and downwards from the movable groove 3 to open them. At the same time, the pin 8 will also be moved out of the groove 11. After that, the bracket 5 can be lifted and all components indirectly or directly mounted on the bracket 5 can be moved outwards and removed. It should be noted that the components indirectly or directly mounted on the bracket 5 and the bracket 5 together form the "tire module", making the search and rescue divided into two parts: the "tire module" and the "main module". Then, the pin 8 will be pulled out of the socket 12, the output shaft 9 will be moved out of the end cover 7, and the drive shaft 6 will be moved out of the slot 10. Finally, the disassembly of the "tire module" is completed. Then, flip the vehicle's "tire module" so that the tracks are facing down. At this time, the tires will be turned upwards. Then, align the "tire module" with the "main module" so that the drive shaft 6 is aligned with the output shaft. Insert the slot 10 on the output shaft 9 into the end block 2. At the same time, the end cover 7 will be tightly pressed against the end block 2, and the output shaft 9 will be inserted into the end cover 7. Simultaneously, the pin 8 will be inserted into the corresponding socket 12 and the movable slot 3. Then, lower the retaining arm 4. As the retaining arm 4 is lowered, the pin 8 will be engaged in the groove 11. Then, insert all the fastening bolts 13 into the bolt holes 14 on the retaining arm 4, and then through the bolt holes 14 until the fastening bolts 13 are inserted into the bolt holes 19 on the pin 8. Finally, tighten them. By fixing bolt 13, pin 8 can be fixed to end block 2, and end cover 7 can also be fixed to end block 2. Finally, the installation of "tire module" is completed. When pin 8 is inserted into the insertion hole 12, the insertion hole 12 can limit pin 8 and prevent end cover 7 from rotating. This improves the stability of the "tire module" after installation. In this way, the track mode of the search and rescue device is switched, enabling the search and rescue device to carry out search and rescue work normally in complex environments with mud and potholes, providing convenience for users.
[0029] When increased speed is required, simply switch the vehicle from track mode to tire mode. Following the disassembly and assembly process described above, remove the fastening bolt 13, then flip and unfold the locking arm 4. Next, remove the bracket 5 along with the drive shaft 6 from the output shaft 9, and simultaneously remove the end cover 7 from the end block 2. Finally, remove the entire "tire module," then flip it 180 degrees so that the tire 17 faces down and the track 16 faces up, lifting it off the ground. Then, following the installation process described above, align the drive shaft 6 with the output shaft 9 and insert it into the slot 10, ensuring the pin 8 passes through the insertion hole 12 and is inserted into the movable slot 3. Afterward, lower the locking arm 4 and insert the fastening bolt 13 back into bolt holes 14 and 19. Finally, tighten the fastening bolt 13 to secure it. After completing the installation of the "tire module," the tire mode switch is complete, enabling the search and rescue device to travel quickly on flat, dry roads, shortening rescue time, improving rescue efficiency, and providing convenience for users. For specific installation details, users can refer to the actual tire changing process on a vehicle; for example, first lift one side of the vehicle to change the tire, then lower it. It should be noted that search and rescue devices vary in size; therefore, the "tire modules" in this solution also vary in size to meet compatibility requirements. Larger "tire modules" match larger equipment, and smaller "tire modules" match smaller equipment. Where the device can be lifted manually, the "tire modules" can also be changed manually to meet actual work needs. However, during operation, starting the main body 1 of the device will cause the output shaft 9 to rotate, which in turn will drive the transmission shaft 6 to rotate. Since the end cover 7 is fixed to the end block 2, the transmission shaft 6 rotates on the end cover 7. Finally, the transmission shaft 6 drives the track wheel 15 or the tire 17 to rotate, allowing the search and rescue device to move normally. The tire 17 is mounted on the transmission shaft 6 and is also driven by the transmission shaft 6, which in turn is driven by the output shaft 9. Therefore, the connection between the transmission shaft 6 and the output shaft 9 is achieved by inserting the end of the transmission shaft 6 into the slot 10. Furthermore, the end of the transmission shaft 6 inserted into the slot 10 has a protrusion, and the shape of the inner cavity of the slot 10 is adapted to this protrusion, thus ensuring... To ensure the smoothness and stability of the machine's power transmission and guarantee the normal operation of the search and rescue device, providing convenience for users, the groove 11 is designed to ensure that the locking arm 4 can match the pin 8. This allows the locking arm 4 and pin 8 to overlap, enabling the fastening bolt 13 to fix the pin 8 and locking arm 4 together. It also ensures that the locking arm 4 can be fully engaged in the movable groove 3, providing convenience for users. The insertion hole 12 is used to insert the pin 8. During installation, the pin 8 is simply inserted into the insertion hole 12. With the cooperation of the insertion hole 12 and the pin 8, the end cover 7 and the entire tire and track installation are positioned, improving the stability of the tire and track installation and providing convenience for users.Bolt hole 14 and bolt hole 19 are both used to install fastening bolt 13. When installing fastening bolt 13, it can be simultaneously inserted into both bolt hole 14 and bolt hole 19, thus fixing the locking arm 4 and the pin 8 together. This ensures the stability of the tire and track installation and provides convenience for the user. The track wheel 15 is driven by the drive shaft 6, which in turn is driven by the output shaft 9. Therefore, when the equipment starts and drives the output shaft 9 to rotate, the output shaft 9 will drive the drive shaft 6 to rotate, which in turn will drive the track wheel. When track wheel 15 rotates, it drives track 16 to rotate. Simultaneously, auxiliary wheels 18 are also driven to rotate by track 16. This allows the entire track to operate normally, providing convenience for the user. Multiple auxiliary wheels 18 are adapted to multiple track wheels 15. The auxiliary wheels 18 and track wheels 15 work together to support track 16, while track 16 also drives the auxiliary wheels 18 and track wheels 15 to rotate simultaneously. This ensures the normal operation of the search and rescue device, improves its stability, and provides convenience for the user.
[0030] Therefore, the structural design allows for flexible switching of driving modes on the same equipment according to work requirements. On dry and flat roads, it can switch to tire driving mode to increase driving speed and improve search and rescue efficiency. On muddy and potholed roads, it can switch to tracked mode so that the search and rescue vehicle will not slip and can still move forward normally to complete the search and rescue work, thereby improving search and rescue efficiency and providing convenience for users.
[0031] The output shaft 9 has a slot 10 at one end facing the transmission shaft 6 that is adapted to the transmission shaft 6, and a tire 17 mounted on the transmission shaft 6 is provided on the outer side of the bracket 5.
[0032] Specifically, regarding the arrangement of slot 10 and tire 17, tire 17 is mounted on drive shaft 6 and is driven by drive shaft 6. Drive shaft 6 is driven by output shaft 9. Therefore, the connection between drive shaft 6 and output shaft 9 is achieved by inserting the end of drive shaft 6 into slot 10. Furthermore, a protrusion is provided at the end of drive shaft 6 inserted into slot 10, and the shape of the inner cavity of slot 10 is adapted to the protrusion, thereby ensuring the smoothness and stability of machine power transmission, ensuring the normal operation of the search and rescue device, and providing convenience for users' work.
[0033] The inner side of the locking arm 4 is provided with a groove 11, and the pin 8 is inserted into the corresponding groove 11.
[0034] Specifically, the groove 11 is designed to ensure that the locking arm 4 can match the pin 8, so that the locking arm 4 and the pin 8 can overlap, allowing the fastening bolt 13 to fix the pin 8 and the locking arm 4 together. It also ensures that the locking arm 4 can be fully inserted into the movable groove 3, providing convenience for the user's work.
[0035] The top and bottom of one side of the end block 2 are provided with insertion holes 12, and one end of the pin 8 is inserted into the corresponding insertion hole 12.
[0036] Specifically, the socket 12 is used to insert the pin 8. During installation, the pin 8 is simply inserted into the socket 12. With the cooperation of the socket 12 and the pin 8, the end cover 7 and the entire tire and track can be positioned, improving the stability of the tire and track installation and providing convenience for the user's work.
[0037] The outer side of the clamping arm 4 is provided with a bolt hole 14 that is compatible with the fastening bolt 13, and the side of the pin 8 is provided with a bolt hole 19 that is compatible with the fastening bolt 13.
[0038] Specifically, the bolt holes 14 and 19 are designed to install fastening bolts 13. When installing fastening bolts 13, they can be inserted into both bolt holes 14 and 19 simultaneously, thereby fixing the clamping arm 4 and the pin 8 together, ensuring the stability of the tire and track installation, and providing convenience for the user's work.
[0039] The drive shaft 6 has a track wheel 15 fixedly mounted on its surface between the tire 17 and the bracket 5, and the two track wheels 15 are connected by the track 16.
[0040] Specifically, the track wheel 15 is driven by the drive shaft 6, which in turn is driven by the output shaft 9. Therefore, when the equipment starts and drives the output shaft 9 to rotate, the output shaft 9 will drive the drive shaft 6 to rotate, which in turn will drive the track wheel 15 to rotate. Then, the track wheel 15 will drive the track 16 to rotate, and at the same time, the auxiliary wheel 18 will also be driven to rotate by the track 16. In this way, the entire track can work normally and provide convenience for the user's work.
[0041] Multiple auxiliary wheels 18 are rotatably mounted on the bottom of one side of the bracket 5, and all the auxiliary wheels 18 are located below the tire 17.
[0042] Specifically, the auxiliary wheels 18 are configured such that multiple auxiliary wheels 18 are adapted to multiple track wheels 15. The multiple auxiliary wheels 18 and track wheels 15 work together to support the track 16. At the same time, the track 16 can also drive the multiple auxiliary wheels 18 and track wheels 15 to rotate simultaneously, thereby ensuring the normal operation of the search and rescue device, improving the driving stability of the search and rescue device, and providing convenience for users' work.
