For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0036] The following is combined with Figures 1 to 8 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0037] The embodiment of the present application discloses a front protection device and a fire truck having the front protection device, wherein the front protection device comprises a mounting seat 10, a front bumper 20 and a fire monitor 30. The mounting seat 10 is used to be fixed to the lower front part of the fire truck, mainly for supporting. The bottom of the front bumper 20 is rotatably connected to the mounting seat 10 so as to be switchable between an extended position and a retracted position relative to the mounting seat 10; the fire monitor 30 is arranged on the front bumper 20.
[0038] Thus, in this embodiment, the fire monitor 30 is arranged on the front bumper 20, and the bottom of the front bumper is rotatably connected to the mounting seat 10, so that the front bumper 20 can rotate relative to the mounting seat 10 with the fire monitor 30. In this way, under normal circumstances, the front bumper 20 is in the folded position to cushion the frontal impact and improve driving safety; when maintenance is needed, it is only necessary to switch the front bumper 20 to the unfolded position. At this time, the front bumper 20 is tilted forward relative to the mounting seat 10, so that the top of the front bumper 20 and the fire monitor 30 can be away from the engine compartment 50 of the fire truck to leave space, thereby facilitating the flipping of the cab or hood of the fire truck. At the same time, the front bumper 20 supports the fire monitor 30 and can also protect the fire monitor 30 during flipping, ensuring that the fire monitor 30 does not fall to the ground.
[0039] The front bumper 20 specifically includes two connecting columns 21 and a frame structure 22 installed on the connecting columns 21. The two connecting columns 21 are rotatably connected to the two sides of the mounting base 10 respectively, so that the weight of the front bumper 20 can be more evenly loaded on the mounting base 10, ensuring the reliability of the fixation of the front bumper 20 on the mounting base 10.
[0040] The mounting base 10 is provided with a rotatable shaft, and the two ends of the shaft extend from the two sides of the mounting base 10 respectively, and the two ends of the shaft are fixedly connected to the two connecting columns 21 respectively, so that the mounting base 10 and the front bumper 20 can be rotatably connected.
[0041] Among them, a nylon pad 11 is mounted on the rotating shaft between the mounting seat 10 and the connecting column 21. The nylon pad 11 can effectively reduce the impact force between the connecting column 21 and the mounting seat 10, protect the surfaces facing the connecting column 21 and the mounting seat 10 from scratches or wear, and extend the service life.
[0042] In this embodiment, the front protection device also includes a limit seat 41 fixed on the front side of the mounting seat 10. When the front bumper 20 is in the deployed position, under the action of the self-weight of the front bumper 20 and the pulling force of the operator, the frame structure 22 of the front bumper 20 will move in a circular motion around the central axis of the rotating shaft through the connecting column 21 to move away from the engine compartment 50, so that the connecting column 21 can abut against the limit seat 41, and the front bumper 20 and the fire monitor 30 installed on the front bumper 20 can be supported by the limit seat 41.
[0043] Of course, it is understandable that a flexible or elastic buffer pad can be provided on the surface of the limiting seat 41 facing the front bumper 20 , so as to protect the contact portion between the limiting seat 41 and the connecting column 21 .
[0044] Specifically, a winch box assembly 40 is fixed in front of the mounting seat 10, and a limited position seat 41 is set on both sides of the winch box assembly 40. The winch box assembly 40 has strong traction, durability and reliability, can adapt to various harsh environments and emergency situations, and is an indispensable auxiliary tool in firefighting and rescue operations. For example, when performing firefighting and rescue tasks, if the fire truck itself accidentally falls into mud, snow, beach or other complex terrain, the front winch can provide strong traction to help the vehicle get out of trouble. Similarly, it can also be used to rescue other vehicles or heavy equipment in similar predicaments. At the scene of a fire or an accident, the winch can quickly clear roadblocks, such as removing fallen trees, wreckage or obstructing vehicles, to ensure that the rescue channel is unobstructed. When operating on a slope or unstable ground, the winch can be used as a fixed point to stabilize the vehicle or slowly drag heavy objects to increase the safety of the operation. In some cases, the winch can help deploy heavy rescue equipment, such as dragging rescue ladders, bridges or large pumping equipment into place. The winch can also be used to lift or pull heavy objects, such as in complex rescue scenarios, to help lift or pull trapped people, equipment or other heavy objects.
[0045] There are connecting parts 12 extending outward on both sides of the mounting seat 10. When the front bumper 20 is in the folded position, the connecting part 12 can be detachably connected to the connecting column 21, so that under normal circumstances, the front bumper 20 is folded in front of the engine compartment 50 to ensure safety during driving and buffer the energy of frontal collision.
[0046] The connection column 21 and the connection part 12 can be detachably connected by screwing. For example, the connection column 21 of the front bumper 20 is provided with a through countersunk through hole, and the connection part 12 is provided with a threaded hole. The screw passes through the countersunk through hole and is locked into the threaded hole to achieve detachable connection between the connection part 12 and the front bumper 20. A sealing hole plug 23 is installed in the countersunk through hole, so that after the screw connects the connection part 12 and the connection column 21, the countersunk through hole can be sealed by the sealing hole plug 23 to prevent the accumulation of debris.
[0047] A mounting platform 24 is connected to the bottom of the front bumper 20 , specifically, the mounting platform 24 is connected to the connecting column 21 , the fire monitor 30 is mounted on the mounting platform 24 , and the liquid inlet pipe of the fire monitor 30 is passed through the mounting platform 24 so as to be connected to the liquid supply system of the fire truck.
[0048] In summary, the embodiment of the present application discloses a front protection device and a fire truck, in which a fire cannon 30 is arranged on the front bumper 20, and the bottom of the front bumper is rotatably connected to the mounting seat 10. Therefore, the front bumper 20 can rotate relative to the mounting seat 10 with the fire cannon 30. In this way, under normal circumstances, the front bumper 20 is in the folded position to cushion the frontal impact and improve the driving safety. When maintenance is needed, it is only necessary to switch the front bumper 20 to the deployed position. At this time, the front bumper 20 is tilted forward relative to the mounting seat 10, so that the top of the front bumper 20 and the fire cannon 30 can be away from the engine compartment 50 of the fire truck to leave space, thereby facilitating the flipping of the cab or hood of the fire truck. At the same time, the front bumper 20 supports the fire cannon 30 and can also protect the fire cannon 30 during flipping, ensuring that the fire cannon 30 does not fall to the ground.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
