[0017] 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.

[0018] Please see Figure 4 An electric tracked stair-climbing fire-fighting equipment trailer includes a frame 1. A drive mechanism is installed at the bottom of the frame 1. The drive mechanism includes a battery 10, a motor 11, rubber tracks and a chassis 12, and a stabilizer 13. The upper surface of the battery 10 is fixedly installed to the bottom of the frame 1. The upper surface of the motor 11 is fixedly installed to the bottom of the frame 1, and the motor 11 is electrically connected to the battery 10. The internal drive components of the rubber tracks and chassis 12 are fixedly installed to the outer surface of the output shaft of the motor 11. The stabilizer 13 is fixedly installed at the bottom of the frame 1, and the outer surface of the stabilizer 13 shaft is rotatably mounted to the inside of the rubber tracks and chassis 12.

[0019] Specifically, the battery 10 provides power to the motor 11, enabling the trailer to have electric drive capability without the need for an external power source, making operation more convenient and flexible. The motor 11 is electrically connected to the battery 10, and drives the rubber tracks and the drive components inside the chassis 12 through the motor 11 to realize the automatic movement of the trailer. This reduces the physical burden on firefighters in carrying fire-fighting equipment and improves rescue efficiency. During the movement of the trailer, the stabilizer 13 can effectively distribute the pressure on the tracks, reduce track wear and deformation, extend the service life of the trailer, and at the same time ensure the stability of the trailer when climbing stairs, reducing the risk of fire-fighting equipment falling due to shaking.

[0020] Please see Figure 3 A baffle 2 is fixedly installed on the left side of the frame 1, and multiple sets of movable wheels 3 are provided on the left side of the baffle 2.

[0021] Specifically, the multiple sets of movable wheels 3 set on the left side of the baffle 2 play an important role when the trailer moves on flat ground. The multiple sets of movable wheels 3 can distribute the pressure of the trailer on the ground, making the trailer move more easily and smoothly on flat ground, reducing the resistance when dragging, and reducing the physical exertion of the operator.

[0022] Please see Figure 1 and Figure 2 The right side of the frame 1 is equipped with a control panel 6 for driving the overall driving operation. A support block 4 is fixedly installed in the center of the right side of the frame 1. Two sets of elastic straps 5 are provided on the upper surface of the support block 4, and the left side of the elastic straps 5 is engaged with the upper surface of the baffle 2. A hose fixing bracket 7 is fixedly installed on the upper surface of the frame 1 for placing fire hoses. Pulling brackets 8 are fixedly installed on both sides of the right end of the frame 1. Handrail brackets 9 are fixedly installed on both sides of the lower surface of the right end of the frame 1.

[0023] Specifically, the pull frame 8 fixedly installed on both sides of the right end of the frame 1 and the handrail frame 9 fixedly installed on both sides of the lower right surface provide multiple assistance methods for the movement of the trailer in different scenarios. When the trailer needs to move a long distance on flat ground or encounters narrow spaces requiring manual assistance, the operator can apply pulling force through the pull frame 8 to easily drag the trailer forward. In scenarios requiring precise control of the trailer's position or additional support and force, such as climbing stairs, the handrail frame 9 can provide a stable support point for the operator, making it easier for the operator to push or adjust the trailer's posture, thus enhancing the trailer's operability and flexibility. The vehicle frame 1 is equipped with a hose fixing bracket 7, which is specifically designed to hold stacked fire hoses. The hose fixing bracket 7 can neatly store and fix the fire hoses, preventing them from getting tangled or knotted during transportation. This not only saves time in organizing the hoses but also ensures that they can be quickly and smoothly deployed when laid, improving the efficiency of fire fighting and rescue. The control panel 6 allows for easy control of the trailer's overall driving direction, speed, and other parameters, greatly improving the convenience and efficiency of operation. This enables the trailer to respond quickly to operating commands and reach the fire scene or designated location in a timely manner. The vehicle frame 1 also features a receiving block 4 fixedly installed in the center of the right side and two sets of elastic straps 5 on its upper surface. The left side of the elastic straps 5 is engaged with the upper surface of the baffle 2. This effectively prevents fire equipment from falling or shifting due to shaking when climbing stairs or passing through bumpy roads, ensuring that the fire equipment is always in a safe and stable state and can be quickly retrieved when needed, thus improving the reliability of rescue operations.

[0024] Working principle: During use, firefighters place the rolled-up fire hose on the hose fixing frame 7 and properly place other fire-fighting and rescue equipment, such as demolition tools and spare gas cylinders, on the bearing surface of the frame 1. Then, they use elastic straps 5 to securely bind and fix these items, with one end of the elastic straps 5 being attached to the baffle 2. After arriving at the work site, the firefighter operates the switch on the control panel 6 to activate the system. The battery 10 begins to supply power to the motor 11. The firefighter controls the direction and speed of the motor 11 through the control panel 6. The power generated by the motor 11 drives the rubber tracks and chassis 12 to move, thereby enabling the trailer to move forward, backward, and turn. During this process, the stabilizing frame 13 plays a key role, ensuring a stable connection between the rubber tracks and chassis 12 and the frame 1, keeping the trailer balanced during movement. When encountering stairs or rugged terrain, firefighters can use the handrail 9 and the pulling frame 8 to assist in controlling the direction and applying traction. Under the powerful driving force of the motor 11, the rubber tracks and chassis 12 can continuously contact the edges of the steps, generating sufficient traction to overcome gravity and achieve a smooth stair climbing action, automatically transporting equipment to the upper floor. During the ascent, the fire hose placed on the hose fixing frame 7 will automatically unfold and lay out under the traction of the trailer and its own weight, and the firefighters only need to guide it from behind.
