[ EXAMPLES one ]
As shown in fig. 1 to 5, an embodiment of the present invention provides a dual rear axle independent dual-layer turnover pedal, which is installed on a fire truck skeleton 3 on both sides of a dual rear axle 17 of a fire truck, the dual rear axle independent dual-layer turnover pedal includes a first-level pedal skeleton assembly 1 and a second-level pedal skeleton assembly 2, the fire truck skeleton 3 is fixedly connected with a pedal mounting plate 4, the pedal mounting plate 4 is provided with a first rotating shaft assembly 5, the first rotating shaft assembly 5 is connected with a cantilever plate 6, and the cantilever plate 6 is fixedly connected with the first-level pedal skeleton assembly 1; fixedly connected with footboard mount pad 7 on the fire engine skeleton 3, be equipped with second pivot assembly 8 on the footboard mount pad 7, second pivot assembly 8 is connected with cantilever beam 9, cantilever beam 9 and second grade footboard skeleton assembly 2 fixed connection. Wherein, one-level footboard skeleton assembly 1 and second grade footboard skeleton assembly 2 all adopt high strength alloy steel rectangle steel pipe welding to form, and simple structure arranges rationally, effectively improves footboard skeleton's bearing capacity, for example 3 meters long-term biggest bearing of two-stage footboard is 350kg, can satisfy many people and get on the footboard and put the equipment simultaneously. The first-stage pedal framework assembly 1 is welded with the cantilever plate 6, the pedal mounting plate 4 is welded with the fire truck framework 3, and the first-stage pedal framework assembly 1 is connected with the fire truck framework 3 through the first rotating shaft assembly 5; second grade footboard skeleton assembly 2 and cantilever beam 9 welding, footboard mount pad 7 and the welding of fire engine skeleton 3 realize being connected of second grade footboard skeleton assembly 2 and fire engine skeleton 3 through second pivot assembly 8, and firm in connection reliable when using with the second grade footboard can be guaranteed to this structure one-level. The first-stage pedal framework assembly 1 realizes the overturning function through the cantilever plate 6 and the first rotating shaft assembly 5, and the second-stage pedal framework assembly 2 realizes the overturning function through the cantilever beam 9 and the second rotating shaft assembly 8.
The double-rear-axle independent double-layer overturning pedal in the embodiment of the utility model is arranged on the fire truck frameworks 3 at two sides of the double-rear-axle 17 of the fire truck, is suitable for double-rear-axle fire trucks and is divided into a first-level pedal and a second-level pedal, and when taking and placing fire-fighting equipment at a lower position in a fire truck carriage, the requirement can be met only by opening the first-level pedal; when taking and placing the fire-fighting equipment at a higher position in the fire fighting truck carriage, opening the primary pedal and the secondary pedal, and allowing a fire fighter to stand on the secondary pedal through the primary pedal to take and place the fire-fighting equipment; simultaneously, one-level footboard and second grade footboard can be split alone and use, if the fire engine carriage height is not high, when getting of fire-fighting equipment need not the two-stage footboard, optional dress one-level footboard.
The double-rear-axle independent double-layer overturning pedal further comprises a first air spring 10 and a second air spring 11, one end of the first air spring 10 is rotatably connected with the cantilever plate 6, and the other end of the first air spring is rotatably connected with the fire fighting truck framework 3; one end of a second air spring 11 is rotatably connected with the cantilever beam 9, and the other end of the second air spring is rotatably connected with the fire fighting truck framework 3. Through first, second air spring 10, 11 provide the helping hand when closing one-level footboard skeleton assembly 1 and second grade footboard skeleton assembly 2, solve because this novel footboard length is longer, the dead weight of footboard is heavier, the problem that can't rely on the manpower to realize completely closing of footboard realizes also can easily close the footboard alone. In some embodiments, a first gas spring mounting 12 and a second gas spring mounting 13 are fixed to the fire engine frame 3, the first gas spring mounting 10 is mounted on the first gas spring mounting 12, and the second gas spring 11 is mounted on the second gas spring mounting 13. The one-level footboard all has solitary air spring and mount pad with the second grade footboard, installs respectively in the different positions of fire engine skeleton 3, guarantees that two-layer footboard can separate alone the use also can make up the use.
When the first gas spring 10 and the second gas spring 11 are respectively in a contraction state, the first-stage pedal framework assembly 1 and the second-stage pedal framework assembly 2 are respectively in a horizontal state for treading; when the first gas spring 10 and the second gas spring 11 are respectively in the extended state, the first-stage pedal skeleton assembly 1 and the second-stage pedal skeleton assembly 2 are respectively in the vertical state to be retracted.
A limiting pin 14 is arranged on the cantilever plate 6, and a limiting hole matched with the limiting pin 14 is arranged on the fire fighting truck framework 3; when the first-stage pedal framework assembly 1 is in a vertical state, the limiting pin 14 can be inserted into the limiting hole, so that the closed state of the first-stage pedal framework assembly 1 is stable, and the driving safety is ensured; the one-level pedal framework assembly 1 and the second gas spring 11 in the closing state can limit the second-level pedal framework assembly 2 in the closing state, so that the second-level pedal framework assembly 2 cannot be automatically opened in the running process. The cantilever beam 9 is constructed so that the pedal is in a horizontal position when opened.
A limiting block 15 is fixed on the fire fighting truck framework 3, the limiting block 15 is welded on the fire fighting truck framework 3, and the limiting block 15 is used for limiting the level of the first-level pedal framework assembly 1.
The second-level pedal framework assembly 2 comprises a cross beam, an arc-shaped notch 16 is formed in the cross beam, when the second-level pedal framework assembly 2 is in a vertical state, the arc-shaped notch 16 is located above the wheels and corresponds to the wheels, the phenomenon that the wheels and the second-level pedal framework assembly 2 rub when a vehicle runs due to the fact that a bounce clearance of a rear double-axle structure tire relative to a chassis frame is large is avoided, the running safety of the vehicle is guaranteed, the area of a pedal face is increased as much as possible, and the risk that personnel fall off from the pedals is reduced.
