The threaded block then moves outward via the connecting rod, extending the lifting mechanism and the moving tracks. Simultaneously, the piston rod of the electric cylinder extends, lifting the mounting base and the robot body upward. This allows the robot to be raised to a sufficient height to overcome various tall obstacles, significantly improving its mobility in complex fire scenes.

Description

Technical Field

[0001] This utility model relates to the field of firefighting robot technology, specifically a firefighting robot that is convenient for overcoming obstacles. Background Technology

[0002] In the field of fire rescue, firefighting robots are playing an increasingly important role. With the acceleration of urbanization, urban environments are becoming increasingly complex, and fire scenes are becoming more diverse, often accompanied by unpredictable obstacles such as collapsed building debris and piled-up clutter. These obstacles not only hinder firefighters from quickly entering the fire scene for rescue and firefighting operations, but may also pose a serious threat to their lives.

[0003] Firefighting equipment faces numerous limitations when dealing with complex obstacles. For example, ordinary fire trucks, due to their large size and lack of agile obstacle-crossing capabilities, struggle to maneuver freely and approach the fire source in narrow and chaotic fire scenes. While some small firefighting robots possess some short-range mobility, most cannot traverse higher obstacles, hindering their ability to effectively reach the core of fires when facing large collapsed structures or debris, thus impacting rescue and firefighting efficiency. Therefore, this paper proposes a firefighting robot with convenient obstacle-crossing capabilities to address these issues. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 This embodiment of a fire-fighting robot that facilitates obstacle crossing includes a mounting base 1 and a robot body 2 fixedly connected to the top of the mounting base 1. The inner side of the mounting base 1 is provided with an extension component for obstacle crossing.

[0022] Please see Figure 1 In this embodiment, the extension assembly includes a dual-axis motor 3 fixedly connected to the inner bottom wall of the mounting base 1. The output shaft of the dual-axis motor 3 is fixedly connected to a threaded rod 4. A threaded block 5 is threadedly connected to the outer side of the threaded rod 4. A connecting rod 6 is fixedly connected to the opposite side of the two threaded blocks 5. A fixing block 7 is fixedly connected to the other end of the connecting rod 6. A lifting component 8 is fixedly connected to the bottom of the fixing block 7. A movable track 9 is fixedly connected to the bottom of the lifting component 8.

[0023] Specifically, robotic arms 201 are fixedly connected to the top left and top right sides of the robot body 2, and a vision sensor 202 is fixedly connected to the front of the robot body 2.

[0024] It should be noted that the vision sensor 202 can collect information about the robot's front and surrounding environment in real time, including the position, shape, and size of obstacles, as well as the distribution of other objects on site, and accurately transmit this information to the robot's control system. The robotic arms 201 on both sides can then perform various operational tasks under the instructions of the control system based on the information provided by the vision sensor 202.

[0025] Specifically, the height and width of the threaded block 5 are equal to the height and width inside the mounting base 1, and the threaded block 5 is slidably connected between the inner top wall and the inner bottom wall of the mounting base 1.

[0026] Specifically, the left end of the left threaded rod 4 is rotatably connected to the inner left side wall of the mounting base 1, and the right end of the right threaded rod 4 is rotatably connected to the inner right side wall of the mounting base 1.

[0027] Specifically, there are four connecting rods 6 on both the left and right sides. The four connecting rods 6 on the left side are arranged at the four corners on the left side of the left threaded block 5, and the four connecting rods 6 on the right side are arranged at the four corners on the right side of the right threaded block 5.

[0028] Specifically, the lifting component 8 includes a housing 801 and an electric cylinder 802 fixedly connected to the bottom wall of the housing 801, and the moving track 9 is fixedly connected to the bottom of the corresponding housing 801, and the fixing block 7 is fixedly connected to one end of the piston rod of the corresponding electric cylinder 802.

[0029] It should be noted that the electric cylinder 802 drives the mounting base 1 to rise and fall through the fixed block 7.

[0030] Specifically, the top of the inner side of the housing 801 is provided with a telescopic port that is adapted to the piston rod of the electric cylinder 802, and the piston rod of the electric cylinder 802 is slidably connected to the inner side of the corresponding telescopic port.

[0031] The working principle of the above embodiments is as follows:

[0032] When the vision sensor 202 detects an obstacle ahead and determines that the robot body 2 cannot pass directly, the control system sends a start signal to the dual-axis motor 3. The dual-axis motor 3 starts working, and its two output shafts drive the left threaded rod 4 and the right threaded rod 4 to rotate synchronously. Under the rotation of the threaded rod 4, the threaded block 5 will move horizontally. As the threaded block 5 moves, the connecting rod 6 will push the fixed block 7 to move outward, thereby causing the lifting component 8 and the moving track 9 to extend, providing space to pass through. At the same time, the control system sends a command to the electric cylinder 802, and the piston rod of the electric cylinder 802 begins to extend, driving the mounting base 1 and the robot body 2 to move upward. When the robot body 2 is raised to a sufficient height to pass through the obstacle ahead, the control system controls the electric cylinder 802 to stop working.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
