[0036] A fire truck turnover ladder system comprises an upper-mounted compartment base 1, a ladder 2, a fastening assembly 3, and a damping block 4.

[0037] The upper-mounted compartment base 1;

[0038] The ladder 2 comprises a connecting segment and a main body segment connected end to end, and the connecting segment is rotationally connected with the upper-mounted compartment base 1, so that the ladder 2 reciprocally rotates between a storage position and a working position;

[0039] The fastening assembly 3 is fixedly connected with the upper-mounted compartment base 1, and when the ladder 2 is located at the storage position, the connecting segment is embedded in the fastening assembly 3;

[0040] ​A damping block 4 is fixedly connected to one side of the connecting section, and when the ladder 2 is in the working position, the connecting section abuts against the upper loading compartment base 1 through the damping block 4.

[0041] The present application connects the ladder 2 and the upper loading compartment base 1 through rotation, so that the ladder 2 has a storage state and a working state. The ladder 2 in the storage state only needs a small amount of space inside the compartment, does not occupy the width space outside the compartment body, and the ladder 2 in the working state facilitates personnel to enter the compartment to obtain equipment and to maintain and repair the upper loading components. The overall structure is simple, convenient to use, and has high flexibility and practicality.

[0042] In the embodiment, the lower end of the ladder 2 is connected to the rotating fixed seat 5 through a rotating shaft 6, the rotating fixed seat 5 is fixed on the upper loading compartment base 1 of the fire fighting truck through four hexagonal head bolts 8, a pair of fastening assemblies 3 are fixed on the blocking rod 7 and used for locking the arc-shaped ladder 2, and two damping blocks 4 are fixed on the ladder 2 through four internal hexagonal countersunk head screws 9. When in use, the ladder 2 is rotated to support the damping blocks 4 on the upper loading compartment base 1 of the fire fighting truck, the height of the arc-shaped ladder 2 is reduced, and personnel can conveniently enter the compartment to work.

[0043] The upper loading compartment base 1 is closely connected to the structure of the compartment of the fire fighting truck and serves as the installation base of the ladder system.

At this time, the connecting section of the ladder 2 is fixed on the compartment base through the fastening assembly 3, and the fastening assembly 3 ensures that the ladder 2 will not be accidentally unfolded. Since the ladder 2 is designed to be rotatable, only a small amount of space inside the compartment is occupied when in storage, and the overall width of the fire fighting truck is not affected.

[0048] Working state: When the ladder 2 needs to be used, the operator can rotate the ladder 2 from the storage position to the working position. The lower end of the ladder 2 is connected to the rotating fixed seat 5 through the rotating shaft 6, and the rotating fixed seat 5 is fixed by four hexagonal head bolts 8 to ensure the stability of rotation. As the ladder 2 rotates, the shock-absorbing block 4 comes into contact with the carriage base, providing a buffering effect and preventing damage caused by direct hard contact between the ladder 2 and the carriage base.

[0049] In some embodiments of the present application, a rotating fixed seat 5 and a rotating shaft 6 are also included, the rotating fixed seat 5 is fixedly connected to the upper loading carriage base 1, and the rotating shaft 6 passes through the rotating fixed seat 5, and the end of the connecting segment is sleeved on the periphery of the rotating shaft 6.

[0050] In some embodiments of the present application, the rotating fixed seat 5 includes a bolt 8, a bottom plate, and two side plates, the bottom plate has a plurality of through holes, the bolt 8 passes through the through holes and is threadedly connected to the upper loading carriage base 1, the two side plates are vertically connected to the bottom plate and have opposite through holes, and the two ends of the rotating shaft 6 pass through the opposite through holes, respectively.

[0051] The rotating fixed seat 5 is threadedly connected to the upper loading carriage base 1 through the bolt 8, so that the fixed seat can be stably installed on the assembly equipment.

The two side plates are vertically connected to the bottom plate, forming a frame structure for accommodating the rotating shaft 6.

[0052] The rotating shaft 6 passes through the opposite through holes on the side plates of the rotating fixed seat 5, so that the battery tray or other assembly components can rotate around the rotating shaft 6. The end of the connecting segment is sleeved on the periphery of the rotating shaft 6, so that the position and angle of the connecting segment can be adjusted through the rotating shaft 6.

[0053] The design of the rotating fixed seat 5 provides strong support and ensures the stability of the rotating shaft 6 during rotation, reducing the shaking of the ladder 2 during use. Through the threaded connection of the bolt 8 and the bottom plate, the rotating fixed seat 5 can be conveniently installed on the carriage base without a complex installation process. The design of the rotating fixed seat 5 is compact and does not occupy too much interior space of the carriage, improving the space utilization rate.

[0054] In some embodiments of the present application, a stop bar 7 is also included, the stop bar 7 is fixedly connected to the upper loading carriage base 1 and is spaced apart from the rotating fixed seat 5, and the stop bar 7 bears the fastening assembly 3.

[0055] In some embodiments of the present application, the fastening assembly 3 comprises a fixed plate, an elastic pressing plate and a cover plate, the fixed plate is connected with the stop rod 7, the elastic pressing plate is elastically connected with both ends of the fixed plate, and the cover plate is connected with the elastic pressing plate and covers the fixed plate at least partially, the elastic pressing plate drives the cover plate to move in the direction close to or away from the fixed plate.

[0056] The stop rod 7 is fixedly connected with the upper carriage base 1 and is spaced apart from the rotary fixing seat 5, thereby providing a stable support point for the fastening assembly 3. The stop rod 7 bears the fastening assembly 3, thereby ensuring that the fastening assembly 3 maintains correct position and stability during operation.

[0057] The fixed plate is connected with the stop rod 7 and serves as the main part of the fastening assembly 3. The elastic pressing plate is elastically connected with both ends of the fixed plate and can move within a certain range to adapt to the locking and unlocking of the ladder 2. The cover plate is connected with the elastic pressing plate and covers the fixed plate at least partially, and moves with the elastic pressing plate when the elastic pressing plate moves, thereby achieving fastening or releasing of the ladder 2.

[0058] Due to the arc-shaped structure design of the ladder 2, when the ladder 2 is in the storage state, the connecting section of the ladder 2 is inclined to the upper surface of the upper carriage base 1. The connecting section of the ladder 2 is raised by the stop rod 7, and the ladder 2 is limited by the rotary fixing seat 5 at two points. The design of the stop rod 7 increases the stability of the entire ladder system, thereby ensuring that displacement does not occur. The design of the elastic pressing plate and the cover plate of the fastening assembly 3 can ensure that the ladder 2 is firmly fixed when in the storage position, thereby preventing accidental falling. The structural design of the fastening assembly 3 is simple to operate and can achieve fastening and releasing of the ladder 2 by simple actions. The design of the fastening assembly 3 is compact and does not occupy additional space, thereby being suitable for installation in the limited space inside the carriage.

[0059] In some embodiments of the present application, the damping block 4 has an arc-shaped groove on the side surface facing the connecting section, the arc-shaped groove matches the outer surface of the connecting section, and the side surface of the damping block 4 away from the connecting section is flat.

[0060] In some embodiments of the present application, the damping block 4 comprises a countersunk screw 9 and a block, the block has a countersunk hole on the side away from the connecting section, and the countersunk screw 9 connects the block and the connecting section through the countersunk hole.

[0061] The side surface of the damping block 4 facing the connecting section has an arc-shaped groove matching the outer surface of the connecting section, so that the damping block 4 can closely fit on the connecting section.

[0062] The side surface of the damping block 4 away from the connecting section is flat, thereby facilitating contact with the carriage base and serving as a support.

[0063] The shock-absorbing block 4 includes a countersunk screw 9 and a block body, and the block body has a countersunk hole away from one side of the connecting segment. The countersunk screw 9 connects the block body and the connecting segment through the countersunk hole, ensuring that the shock-absorbing block 4 is firmly fixed on the connecting segment.

[0064] The design of the arc-shaped groove can absorb and disperse the impact force generated during the turning and operation of the ladder 2, reducing the damage to the carriage base. The arc-shaped groove of the shock-absorbing block 4 matches the outer surface of the connecting segment, ensuring the close fit of the shock-absorbing block 4 and the connecting segment, improving stability. The fixing method of the countersunk screw 9 simplifies the installation process, facilitating quick installation and disassembly of the shock-absorbing block 4. The presence of the shock-absorbing block 4 reduces the possibility of hard collision of the ladder 2 during turning, improving the safety of the operator. The material and design of the shock-absorbing block 4 enable it to withstand long-term use and external environmental erosion, prolonging the service life of the entire system.

[0065] In some embodiments of the present application, the included angle between the connecting segment and the main body segment is obtuse.

[0066] In some embodiments of the present application, when the ladder 2 is in the storage position, the extension direction of the main body segment is perpendicular to the upper surface of the upper loading carriage base 1.

[0067] In some embodiments of the present application, when the ladder 2 is in the working position, the extension direction of the connecting segment is parallel to the upper surface of the upper loading carriage base 1.

[0068] The included angle between the connecting segment and the main body segment is obtuse, which means that the overall length and width of the ladder 2 are comprehensively considered while ensuring its practicality. This design helps to balance the overall length and width of the ladder 2, making it more compact and convenient to store.

[0069] When the ladder 2 is in the storage position, the extension direction of the main body segment is perpendicular to the upper surface of the upper loading carriage base 1, which means that the main body segment is placed vertically, saving horizontal space. This design ensures that the ladder 2 does not occupy too much space in the vehicle when not in use, improving the accessibility and efficiency of other equipment in the carriage.

[0070] When the ladder 2 is in the working position, the extension direction of the connecting segment is parallel to the upper surface of the upper loading carriage base 1, which means that the connecting segment is placed horizontally, providing a stable step for the user. This design ensures the stability and safety of the ladder 2 during use, facilitating quick and safe climbing for firefighters.

[0071] By vertically placing the body section when in the storage position, the space in the vehicle compartment is saved, so that the vehicle compartment can load more rescue equipment or other materials. The horizontal connecting section of the ladder 2 in the working position provides stable steps, so that the user can easily climb. The structural design of the ladder 2 enables it to quickly switch from the storage position to the working position, improving the efficiency of emergency response.
