Description

Technical Field

[0001] This utility model belongs to the field of fire protection facilities technology, specifically relating to a portable fire-fighting robot quick loading and unloading device for fire trucks. Background Technology

[0002] In firefighting and rescue operations, there may be "last mile" sections of roads that are narrow and have harsh environments, making them inaccessible to fire trucks. In such cases, a firefighting robot is necessary. With technological advancements, firefighting robots have become crucial equipment for handling complex and dangerous fire scenarios. However, these robots require separate transport vehicles to reach the scene, or small portable robots may be placed inside fire trucks. Upon arrival, firefighters must manually lift them off the truck or push them down using simple ramps. This approach has significant drawbacks: first, it requires multiple firefighters to coordinate untying, carrying, and placement operations, relying heavily on manpower and resulting in lengthy deployment times that severely impact the critical window for firefighting and rescue; second, it places a heavy physical burden on firefighters, especially when wearing heavy protective suits. Utility Model Content

[0003] This utility model addresses the technical problem of existing portable fire-fighting robots being difficult to load and unload from fire trucks, which is time-consuming and laborious, by providing a device for quickly loading and unloading portable fire-fighting robots from fire trucks.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A portable fire-fighting robot rapid loading and unloading device for fire trucks includes a fire truck, a parking frame, and an inclined frame; the lower rear of the fire truck has a hollow structure; the parking frame is fixedly installed in the hollow structure, with one end fixedly connected to the fire truck and the other end hinged to the bottom surface of the inclined frame; the tail ends of linear drive rods are hinged to the upper sides of both sides of the parking frame; the power output ends of the linear drive rods are respectively hinged to the guard plates on both sides of the inclined frame.

[0005] Furthermore, magnetic navigation strips are laid and fixed at the bottom of the parking frame and the bottom of the inclined frame along the direction of movement of the portable fire extinguishing robot; a magnetic navigator is fixedly installed at the bottom front of the portable fire extinguishing robot.

[0006] Furthermore, an electromagnet is fixedly installed at the end of the magnetic navigation strip at the bottom of the parking frame.

[0007] Furthermore, the four power wheels of the portable fire extinguishing robot are respectively connected to the power output ends of four swing arm motors through four swing arm rods; the swing arm motors are fixedly installed at the four corners of the chassis of the portable fire extinguishing robot.

[0008] Furthermore, rubber anti-collision strips are fixedly installed on the lower inner sides of the parking frame and the inclined frame.

[0009] Compared to existing technologies, this invention utilizes the cooperation of multiple components to create a ramp suitable for the rapid ascent and descent of portable firefighting robots, significantly improving response speed and enabling rapid deployment of the robots. Furthermore, the integration of magnetic navigation and a swing-arm leveling system enhances the robot's stability on slopes, reducing the risk of tipping over. The combined use of electromagnetic locking and anti-collision strips improves transportation safety and significantly reduces equipment damage rates. Attached Figure Description

Detailed Implementation

[0012] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0014] For examples, see Figure 1-6 , A rapid loading and unloading device for a portable fire-fighting robot on a fire truck includes a fire truck 1, a parking frame 2, and an inclined frame 3. The rear of the fire truck 1 has a hollow structure. The parking frame 2 is fixedly installed in the hollow structure, with one end fixedly connected to the fire truck 1 and the other end open (without a barrier) and hinged to the bottom surface of the inclined frame 3 via a hinge shaft 31. The rear ends of linear drive rods 4 are hinged to the upper sides of both sides of the parking frame 2. The power output ends of the linear drive rods 4 are movably hinged to the guard plates 32 on both sides of the inclined frame 3. Using the inclined frame 3 as a temporary travel support structure, the thrust generated by the synchronous drive of the linear drive rods 4 on both sides drives the inclined frame 3 to open and close around the hinge shaft 31, further forming a ramp suitable for the rapid loading and unloading of the portable fire-fighting robot 5. This greatly improves the response speed and quickly achieves the purpose of rapidly deploying the portable fire-fighting robot 5.

[0015] A magnetic navigation strip 6 is laid and fixed at the bottom of the parking frame 2 and the middle part of the bottom of the inclined frame 3 along the direction of movement of the portable fire extinguishing robot 5; a magnetic navigator 51 is fixedly installed at the bottom front of the portable fire extinguishing robot 5. The magnetic navigation strip 6 located at the middle part of the bottom of the parking frame 2 and the bottom of the inclined frame 3 serves as a guiding path and assists in the reference of the travel path. At the hinge point between the inclined frame 3 and the parking frame 2, the magnetic navigation strip 6 is connected by a flexible joint to ensure the continuity of the magnetic field after deployment.

[0016] The portable fire extinguishing robot 5 has four drive wheels 52 connected to the power output ends of four swing arm rods 53 via four swing arm motors 54. The swing arm motors 54 are fixedly mounted at the four corners of the chassis of the portable fire extinguishing robot 5. One end of each swing arm rod 53 is fixedly connected to the power output end of the swing arm motor 54, and the other end is rotatably connected to the axle of the drive wheel 52. Through the combination of the swing arm motors 54, the swing arm rods 53, and the drive wheels 52, the suspension height of the portable fire extinguishing robot 5 can be adjusted, enabling the portable fire extinguishing robot 5 to simultaneously possess stronger terrain adaptability and stability when moving up and down inclined frames 3.

[0017] Furthermore, an electromagnet 7 is fixedly installed at the end of the magnetic navigation strip 6 at the bottom of the parking frame 2. When the portable fire extinguishing robot 5 returns to the parking frame 2 after completing its work, the electromagnet 7 is used to attract and fix the portable fire extinguishing robot 5. Rubber anti-collision strips 8 are fixedly installed on the lower inner sides of both the parking frame 2 and the inclined frame 3 (set at the bottom of the enclosure of the parking frame 2 and the inclined frame 3), which play a role in buffering and shock absorption during transportation.

[0018] During use, in the transportation phase: before the fire truck drives, the portable fire extinguishing robot 5 drives into the parking frame 2 along the magnetic navigation bar 6. After the bottom magnetic navigator 51 detects the signal of the central magnetic navigation bar 6, it automatically corrects its position and drives to the top of the electromagnet 7 inside the parking frame 2. Then the swing arm motor 54 rotates, driving the swing arm rod 53 to rotate at a corresponding angle with a trend of opening outward in parallel and horizontal direction until the chassis of the portable fire extinguishing robot 5 is connected to the electromagnet 7. At this time, the electromagnet 7 is activated to attract and fix the chassis of the portable fire extinguishing robot 5.

[0019] Deployment Phase: After fire truck 1 arrives at the fire scene and comes to a stop, the operator sends a deployment command to the linear drive rods 4. The linear drive rods 4 on both sides extend synchronously, pushing the inclined frame 3 to rotate around the hinge axis to reach the preset angle. Once the linear drive rods 4 are fully extended, the electromagnet 7 cuts off the power, and the magnetic attraction disappears; the swing arm motor 54 rotates, causing the swing arm rod 53 to rotate at a corresponding angle with a tendency to converge inwards from both the vertical and horizontal planes, achieving the optimal stable posture for movement. The portable fire-fighting robot 5 is then ready to depart.

[0020] Disembarking Phase: The portable fire extinguishing robot 5 initiates autonomous driving. The magnetic navigator 51 monitors the magnetic field signal of the magnetic navigation strip 6 in real time. When the signal strength reaches the threshold, it indicates that the portable fire extinguishing robot 5 has aligned with the ramp. The portable fire extinguishing robot 5 moves forward at low speed. After entering the inclined plane 3, the portable fire extinguishing robot 5 detects the change in slope and can also dynamically adjust the swing arm angle through the swing arm motor 54 to ensure that the load such as the water cannon or the adapter component remains horizontal, achieving a smooth transition of the chassis from tilt to near-horizontal.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
