Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to an auxiliary stair-climbing vehicle for fire protection. Background Technology

[0002] A fire-fighting auxiliary stair-climbing vehicle is a vehicle specifically designed to help firefighters climb stairs or perform high-altitude operations in emergency situations. It plays an important role in high-altitude operations, hence the use of an auxiliary stair-climbing vehicle for firefighting.

[0003] To this end, patent CN211215106U discloses a fire truck ladder reinforcement device, including a fire truck, a truck body, and a ladder. The ladder is located at the top of the truck body, and several reinforcement devices are fixedly installed between the truck body and the bottom of the ladder. The reinforcement device consists of a base box and a fixed box. The base box is equipped with a lifting mechanism. This utility model has a simple structure. The fire truck ladder reinforcement device achieves the lifting and reinforcement of the ladder through the coordinated use of the lifting mechanism, motor, drive gear, driven gear, screw, lifting plate, and telescopic column. The motor drives the drive gear to rotate, and the driven gear meshing with the drive gear rotates accordingly, thereby driving the screw to rotate. The lifting plate, which is threaded to the screw, moves up and down on the outer surface of the screw, causing the telescopic column to extend and retract inside the fixed box, thus achieving the purpose of supporting and reinforcing the ladder. At the same time, two screws are provided to effectively distribute the pressure of the ladder on the fixed box, making the fixed box more stable.

[0004] Although the fire truck ladder reinforcement device mentioned above achieves the purpose of supporting and reinforcing the ladder, its inconvenience in adjusting the angle and the angle of the working platform makes it difficult to ensure the stability and safety of the working platform during operation, resulting in poor stability during use. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary stair-climbing vehicle for fire fighting, in order to solve the problem that existing auxiliary stair-climbing vehicles for fire fighting are inconvenient to adjust in angle.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an auxiliary stair-climbing vehicle for fire fighting, comprising a vehicle head and a vehicle body;

[0007] The vehicle body is fixed to one side of the front of the vehicle, and support structures are provided on both sides of the bottom of the vehicle body. A fixed seat is fixed to one side of the top of the vehicle body, and a rotating structure is provided inside the fixed seat. A turntable is provided on one side of the top of the fixed seat.

[0008] A support base is fixed on one side of the top of the turntable, and a second hydraulic telescopic rod is hinged to the other side of the top of the turntable. A support frame is hinged to the top of the support base, and a lifting structure is provided inside the support frame.

[0009] A rubber pad is fixed to the top of the vehicle head, and an adjustment structure is provided at the top of the rubber pad. The adjustment structure includes a working platform, a hinge seat, and a second electric push rod. The working platform is located at the top of the rubber pad, and a hinge seat is fixed to one side of the bottom of the working platform. The second electric push rod is hinged to both ends of one side of the working platform.

[0010] When using this device, the adjustable structure allows for easy angle adjustment, thereby improving the stability of the auxiliary stair-climbing vehicle for firefighting during use; the support structure facilitates support, thus improving safety; the lifting structure facilitates raising and lowering, enhancing convenience; and the rotating structure facilitates rotation, improving applicability.

[0011] Preferably, the support structure includes a fixed frame, threaded rods, movable seats, a first electric push rod, a support plate, a connecting plate, and a first servo motor. The fixed frame is fixed to both sides of the bottom of the vehicle body. A threaded rod is provided inside the fixed frame, and movable seats are threadedly connected to the outer walls of both ends of the threaded rod. A first servo motor is installed on the outer wall of the fixed frame at one end of the threaded rod. The bottom ends of the movable seats extend to the outside of the fixed frame. A connecting plate is fixed to one side of the bottom of each movable seat, and a first electric push rod passes through one side of the inside of each connecting plate. A support plate is fixed to the bottom end of each first electric push rod. When the first servo motor is started, it drives the threaded rod to rotate inside the fixed frame. Because the threads at both ends of the threaded rod are in opposite directions, the threaded rod drives the movable seats at both ends to move in opposite directions. The movable seats and the fixed frame form a sliding structure, enhancing the stability of the movable seats during movement.

[0012] Preferably, one end of the threaded rod extends to the outside of the fixed frame and is fixedly connected to the output end of the first servo motor. The threads at both ends of the threaded rod are in opposite directions, and the movable seat and the fixed frame form a sliding structure. The movable seat drives the connecting plate to move, activating the first electric push rod. The first electric push rod drives the support plate to contact the ground. Under the support of the support plate, it is ensured that the vehicle body will not overturn during operation.

[0013] Preferably, the lifting structure includes a first hydraulic telescopic rod, a ladder, and a sliding plate. The first hydraulic telescopic rod is fixed to one side inside the support frame, with the ladder fixed to one end and the sliding plate fixed to the bottom end of the ladder. Activating the second hydraulic telescopic rod causes the support frame to rotate, resulting in a change in the angle of the support frame at the top of the support base. Activating the first hydraulic telescopic rod then moves the ladder, which in turn moves the sliding plate within the slide groove.

[0014] Preferably, the bottom support frame of the sliding plate has an internal groove, and the sliding plate and the support frame form a sliding structure through the groove. The sliding plate enhances the stability of the ladder during movement, and the ladder moves the work platform via the hinged seat, thereby changing the height of the work platform.

[0015] Preferably, the end of the hinged seat away from the working platform is hinged to one end of the ladder, and the end of the second electric push rod away from the working platform is hinged to the top of the ladder. Activating the second electric push rod causes the working platform to rotate, which in turn causes the hinged seat to rotate within the support frame, thus changing the angle of the working platform and ensuring it remains in a balanced state, guaranteeing the stability and safety of the working platform during operation.

[0016] Preferably, the rotating structure includes a movable slot, a driven gear, a first rotating shaft, a second servo motor, and a driving gear. The movable slot is disposed inside the fixed base. A second rotating shaft is disposed on one side of the movable slot. A driving gear is fixed on the outer wall of the second rotating shaft. A driven gear is meshed with one side of the driving gear. The first rotating shaft passes through the interior of the driven gear. A second servo motor is installed on the top of the fixed base above the second rotating shaft.

[0017] Preferably, the top end of the first rotating shaft extends to the outside of the fixed base and is fixedly connected to the bottom end of the turntable, and the bottom end of the first rotating shaft extends to the inside of the fixed base and forms a rotating structure with the fixed base. The second servo motor is started, driving the second rotating shaft to rotate inside the movable slot. The second rotating shaft drives the drive gear to rotate, and the drive gear drives the first rotating shaft to rotate through the driven gear. The first rotating shaft then drives the turntable to rotate.

[0018] Preferably, the top end of the second rotating shaft passes through the fixed base and is fixedly connected to the output end of the second servo motor, the bottom end of the second rotating shaft extends into the interior of the fixed base and forms a rotating structure with the fixed base, and the end of the second hydraulic telescopic rod away from the turntable is hinged to the bottom end of the support frame. The turntable drives the support frame to rotate through the support base, which can adapt to different rescue scenarios and improve work efficiency.

[0019] The present invention provides an auxiliary stair-climbing vehicle for firefighting, the advantages of which are:

[0020] By setting an adjustment structure, the second electric push rod is activated, which drives the working platform to rotate. The working platform drives the hinge seat to rotate inside the support frame, thereby changing the angle of the working platform and keeping it in a balanced state. This ensures the stability and safety of the working platform during operation and realizes the function of easy angle adjustment, thus improving the stability of the auxiliary stair climbing vehicle used for fire fighting during use.

[0021] By setting up a support structure, the first servo motor is started, which drives the threaded rod to rotate inside the fixed frame. Since the threads at both ends of the threaded rod are in opposite directions, the threaded rod drives the moving seats at both ends to move in opposite directions. The moving seats and the fixed frame form a sliding structure, which enhances the stability of the moving seats during movement. The moving seats drive the connecting plate to move, which starts the first electric push rod. The first electric push rod drives the support plate to contact the ground. Under the support of the support plate, it is ensured that the vehicle body will not overturn during operation, realizing the function of easy support of the device, thereby improving the safety of the auxiliary stair climbing vehicle used for fire fighting during use.

[0022] By incorporating a lifting structure, activating the second hydraulic telescopic rod causes the support frame to rotate, resulting in a change in the angle of the support frame at the top of the support base. This activates the first hydraulic telescopic rod, which moves the ladder. The ladder then moves the sliding plate within the chute, enhancing the stability of the ladder during movement. The ladder, through the hinged seat, moves the working platform, changing its height. This design facilitates lifting and lowering, thus improving the ease of use of this auxiliary stair-climbing vehicle for firefighting.

[0023] By incorporating a rotating structure, the second servo motor is activated, driving the second rotating shaft to rotate within the movable slot. The second rotating shaft then drives the drive gear to rotate, which in turn drives the first rotating shaft to rotate via the driven gear. The first rotating shaft then drives the turntable to rotate, which in turn drives the support frame to rotate via the support base. This design allows the device to adapt to different rescue scenarios, improving work efficiency and enabling easy rotation. Consequently, it enhances the applicability of this auxiliary stair-climbing vehicle used for firefighting. Attached Figure Description
