Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to a fire truck rear axle tilting pedal device and a fire truck. Background Technology

[0002] Currently, fire trucks typically have one or two equipment compartments located above the rear axle tires, often divided into upper and lower levels. While personnel can usually access equipment on the first level from the ground, the equipment on the second level is positioned higher, making it inconvenient for standing personnel to access. To address this, previous designs generally lowered the height of the second level, resulting in a correspondingly lower storage height for the equipment on the first level, thus limiting access. To address this, existing technology has designed a flip-up platform device mounted on the upper part of the tire. When in use, it flips over, allowing personnel to stand on the platform to retrieve equipment from the second level. While this greatly facilitates equipment access, the platform is prone to deformation and downward tilting under pressure, affecting its stability and impacting the user experience. Furthermore, there is a risk of personnel slipping and falling from the platform, posing a safety hazard. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figures 1-6 This invention describes a fire truck rear axle tilting pedal device and a fire truck according to an embodiment of the present invention.

[0020] like Figure 1-4 As shown, this utility model embodiment provides a fire truck rear axle tilting pedal device, including: a mounting base 1, a frame 3, a limiting part 4, and a plate 5; the mounting base 1 is a structural component disposed on the fire truck 2; the frame 3 forms an accommodating space, and one end of the frame 3 is hinged to the mounting base 1; the limiting part 4 is disposed on the mounting base 1 for cooperating with the frame 3; the plate 5 is hinged to the end of the frame 3 away from the mounting base 1; wherein, the frame 3 includes a first position and a second position; in the first position, the frame 3 is perpendicular to the ground, and the plate 5 is perpendicular to the frame 3 and extends toward one side of the fire truck 2; in the second position, the frame 3 cooperates with the limiting part 4, and at least a portion of the plate 5 is embedded into the accommodating space of the frame 3.

[0021] Specifically, in this embodiment, a limiting part 4 is provided on the mounting base 1. The cooperation between the limiting part 4 and the frame 3 can keep the frame 3 stably in the second position and avoid the problem of the frame 3 tilting too downward. In the second position, the plate 5 can be embedded into the receiving space of the frame 3 and integrated with the structure of the frame 3 into a whole, making the overall integrity of the device stronger. Compared with the method of stacking the pedal and the frame 3, the embedding method can distribute the force of the pedal more evenly to the frame 3, which can improve stability and reduce the deformation of the plate 5 and the frame 3.

[0022] In some possible implementations, the mounting base 1 is a rectangular plate with at least two sets of mounting holes, each set of mounting holes including at least two vertically arranged mounting holes. Bolts pass through the mounting holes to fix the mounting base 1 to the structural components of the fire truck 2. It should be understood that the structural components of the fire truck 2 here can be the fenders on the front and rear sides of the tire. The plate body 5 includes a carbon steel frame and an aluminum plate bonded to the surface of the carbon steel frame. The carbon steel frame serves as the main frame, and the aluminum plate serves as the footrest bearing surface.

[0023] It should be understood that in the first position, the frame 3 is perpendicular to the ground and its outer side is basically flush with the side of the fire truck 2. The plate 5 is perpendicular to the frame 3 and extends into the space above the tires of the fire truck 2, that is, the whole device is in the storage state. During the switching from the first position to the second position, the frame 3 is rotated outward to abut against the limiting part 4. At this time, the frame 3 is basically parallel to the ground. The plate 5 is rotated towards the fire truck 2 side until it is at least partially embedded in the receiving space of the frame 3, completing the unfolding of the device. At this time, the whole device is in the working state.

[0024] like Figure 2 As shown, a fire truck rear axle tilting pedal device provided according to an embodiment of the present utility model includes a frame 3 comprising a support frame 31 and a connecting arm 32; one end of the support frame 31 is hinged to the plate 5, and the other end of the support frame 31 extends toward the mounting base 1; one end of the connecting arm 32 is connected to the end of the support frame 31 extending toward the mounting base 1, and the other end of the connecting arm 32 is hinged to the mounting base 1.

[0025] In some possible implementations, the support frame 31 is made of carbon steel skeleton welded together, including U-shaped steel frame, diagonal connecting rods connecting the side rods and bottom rods of U-shaped steel frame, and reinforcing rods connecting the diagonal connecting rods on both sides, forming a stable frame structure. Since the U-shaped steel frame has a certain thickness, the inner side of the U-shaped steel frame has a certain accommodating space when the frame structure is laid flat, which can accommodate the plate 5; the two sides of the plate 5 are provided with notches, which can cooperate with the diagonal connecting rods to avoid positional conflicts.

[0026] In some possible implementations, a buffer is also provided on the diagonal connecting rod. The buffer can be supported by a soft material such as rubber. The buffer is used to provide a cushioning effect when the plate 5 rotates into the receiving space, so as to prevent the plate 5 from being damaged by direct contact with the rigid diagonal connecting rod.

[0027] In some possible implementations, the connecting arm 32 is mounted on the side bar of the U-shaped steel frame and is in the shape of a ring trapezoid, which ensures connection stability while reducing weight and saving materials.

[0028] like Figure 1-2 As shown, a fire truck rear axle tilting pedal device provided according to an embodiment of the present utility model has an abutment part 321 at one end of the connecting arm 32 away from the support frame 31, which is used to abut against the limiting part 4 in the second position to fix the position of the frame 3.

[0029] It is understandable that the distance between the abutting part 321 and the hinge point of the connecting arm 32 is equal to the distance between the limiting part 4 and the hinge point of the connecting arm 32. In other words, the abutting part 321 and the limiting part 4 are on the same circle with the hinge point of the connecting arm 32 as the center, so as to ensure that after the frame 3 rotates to a certain angle, the abutting part 321 can just abut against the limiting part 4 to achieve the limiting function.

[0030] like Figure 2 As shown, a fire truck rear axle tilting pedal device provided according to an embodiment of the present utility model has a limiting part 4 that can extend and retract in the vertical direction to adjust the tilt angle of the support frame 31 relative to the ground in the second position.

[0031] In some possible implementations, the limiting part 4 includes a threaded sleeve fixed on the mounting base 1 and a bolt threadedly connected to the threaded sleeve. The bolt can move vertically along the thread. That is, the longer the bolt extends downward, the greater the tilt of the frame 3 after the abutting part 321 abuts against the bolt. In actual use, the bolt is usually adjusted to make the frame 3 tilt slightly upward to balance the deformation caused by the pressure after the user stands on the plate 5, ensuring that the frame 3 is at least parallel to the ground when someone is standing on it, thereby improving structural stability and reducing the risk of people slipping.

[0032] like Figure 2 As shown, a fire truck rear axle tilting pedal device provided according to an embodiment of the present utility model further includes: a first telescopic rod 6, one end of the first telescopic rod 6 is hinged to the connecting arm 32, and the other end of the first telescopic rod 6 is hinged to the end of the mounting base 1 away from the connecting arm 32.

[0033] According to an embodiment of the present invention, a fire truck rear axle tilting pedal device further includes: a second telescopic rod 7, one end of which is hinged to the inner side of one side of the support frame 31, and the other end of which is hinged to the plate 5.

[0034] In some possible implementations, both the first telescopic rod 6 and the second telescopic rod 7 use gas springs as auxiliary power. When the frame 3 tilts down, gravity is used while the gas springs provide cushioning to prevent the frame 3 from tilting down too quickly and causing excessive impact. When the frame 3 tilts up, the gas springs serve as auxiliary power to reduce the difficulty of operation.

[0035] like Figure 2 As shown, a fire truck rear axle tilting pedal device provided according to an embodiment of the present utility model further includes a panel 33 and a locking part 34; the panel 33 is disposed on the side surface of the support frame 31 away from the fire truck 2; the locking part 34 is disposed on the side of the panel 33 away from the connecting arm 32, and is used to lock the position of the frame 3 in the first position.

[0036] In some possible implementations, panel 33 may be a semi-enclosed structure, covering the side surface of the support frame 31 away from the fire truck 2 and the sides, and is fixed by metal adhesive; locking part 34 may be a flat lock, including a lock body and a lock tongue, wherein the lock tongue may be a rotating or telescopic type, and can engage or insert with the structural components of the fire truck 2 by rotating or telescopically engaging the lock tongue, thereby locking the device in the first position or unlocking it from the first position.

[0037] like Figure 1 As shown, a fire truck rear axle tilting pedal device provided according to an embodiment of the present utility model further includes: a reinforcing rib plate 35, which is disposed on the side surface of the panel 33 away from the support frame 31.

[0038] In some possible implementations, the reinforcing ribs 35 are arranged along the inner circumferential side of the panel 33 and can be fixed to the panel 33 by bolts, thereby strengthening the frame 3 and providing anti-collision protection.

[0039] like Figure 1-4 As shown, a fire truck rear axle tilting pedal device provided according to an embodiment of the present utility model further includes: a warning light 8, which is disposed on the side of the support frame 31 to indicate whether the frame 3 is in the first position.

[0040] Understandably, when the frame 3 is flipped from the first position to the second position, the warning light 8 starts flashing and the indicator device is in the unfolded state, at which point the vehicle cannot be started; after the frame 3 is flipped back to the first position to complete the storage, the warning light 8 goes out, the indicator device is in the stored state, and the vehicle can be started.

[0041] like Figure 5-6 As shown, this utility model embodiment also provides a fire truck, including a sensor and the fire truck rear axle tilting pedal device as described above; the sensor is disposed on the structural component of the fire truck 2, used to sense whether the frame 3 is in the first position, and the sensor is connected to the warning light 8.

[0042] In some possible implementations, the sensor may be two opposing sensors, respectively installed on the front and rear fenders of the tire; when the frame 3 is in the first position, the two sensors are blocked and do not send a signal to the warning light 8, and the warning light 8 is in an off state; when the frame 3 is not in the first position, the two sensors are not blocked and send a signal to the warning light 8, and the warning light 8 begins to flash.

[0043] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
