Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fire-fighting equipment, and in particular to an electric transport vehicle for fire-fighting equipment. Background Technology
[0002] In cities, the density of people living in the city is high, especially in some old communities where many buildings are quite old. In the early stages of construction, people did not pay enough attention to the fire protection facilities of the buildings, resulting in many communities having inadequate fire protection facilities, making them prone to fires. After a fire breaks out, due to the dense population, narrow original roads, and many building alleys, it is difficult for fire rescue vehicles to enter. Therefore, firefighters need to lay water hoses manually and draw water from fire hydrants at a distance. However, when laying water hoses manually, one person can only carry a maximum of two rolls of hose, which limits the length that can be laid and is time-consuming and laborious.
[0003] Therefore, the existing Chinese patent CN220360652U discloses a multi-functional remote-controlled fire extinguishing transport vehicle. This design utilizes a remote-controlled trolley to transport firefighting equipment such as electrically controlled mobile water cannons and hoses. It can easily reach fire scenes in narrow alleyways and roads. Furthermore, the included hose-laying component allows hoses to be laid while the trolley is moving, reducing the physical exertion of firefighters and indirectly improving their work efficiency. However, this design can only transport water cannons and hoses at a time; transporting other firefighting equipment requires disassembling the water cannons and storage boxes, resulting in limited transport capacity. Moreover, after the firefighting mission is completed, the hoses need to be manually wound up, which is laborious and requires further improvement. Utility Model Content

Detailed Implementation
[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0031] like Figures 1 to 9 As shown, an electric fire-fighting equipment transport vehicle 10 of this embodiment includes a frame 1, a hose reel device 2, an electric wheel set 3, and a remote controller 4.
[0032] like Figure 1 The frame 1 includes a chassis 11, a frame body 12, and two flip-up covers 13.
[0033] See Figure 2The frame body 12 is located in the center of the top surface of the chassis 11, and the interior of the frame body 12 has a cavity 14 with an open top surface 141. Two flaps 13 are respectively arranged on the left and right sides of the frame body 12, which can be unfolded and folded. The lower side of the flap 13 is hinged to the bottom of the frame body 12, and when unfolded, the flap 13 forms a side groove 15 with the frame body 12. When folded, the flap 13 rests against the frame body 12. The frame 1 of this embodiment has a cavity 14 and two side grooves 15, which has a large capacity and can accommodate multiple rolls of water hoses, fire monitors, gas cylinders and other fire-fighting equipment, and has a strong carrying capacity. At the same time, the flaps 13 can be folded up to reduce the volume of the frame 1.
[0034] See Figure 3 and Figure 4 The top of the frame body 12 is also provided with a winding bracket 16. One end of the winding bracket 16 is hinged to the top side wall of the cavity 14. After the winding bracket 16 is unfolded, it is placed on the front end of the top of the cavity 14 and extends obliquely upward to the front side of the frame body 12. After the winding bracket 16 is folded, it is flush with the top surface of the cavity 14. The hose winding device 2 includes an overlapping bracket 21 and an electric winding device 22. The overlapping bracket 21 is detachably placed on the unfolded winding bracket 16. The electric winding device 22 is fixedly connected to the overlapping bracket 21, and the electric winding device 22 has a hose winding shaft 221 that extends laterally to one side of the winding bracket 16. Thus, when the winding bracket 16 is lifted, the hose winding device 2 can be placed to raise the electric winding device 22, and the hose winding shaft 221 can be used to conveniently and labor-savingly automatically wind up the hose (e.g., Figure 5 The electric rewinder 22 can be based on existing technology.
[0035] The electric wheel set 3 is installed at the bottom of the chassis 11 of the frame 1; the remote controller 4 is used to control the operation of the electric wheel set 3. Both the electric wheel set 3 and the remote controller 4 can adopt existing structures. The electric wheel set 3 can include 4 electric wheels, each of which is installed at one of the four corners of the chassis 11, allowing the transport vehicle 10 to move forward, turn, etc. automatically under the control of the remote controller 4.
[0036] Therefore, the transport vehicle 10 has a cavity 14 and two side compartments 15 after the flap body 13 is unfolded, which can accommodate a large number of fire-fighting equipment. It can also automatically transport fire-fighting equipment in batches through remote control, effectively saving manpower in places where fire trucks cannot enter, and is more efficient than manual handling. In addition, the transport vehicle 10 also has a retractable support 16 that can be unfolded, which can be used with the hose retractor 2 to achieve efficient and automatic hose retracting, making it convenient and labor-saving to store the hose after the fire-fighting mission is over, saving manpower.
[0037] In this embodiment, the main body 12 of the vehicle frame can be a frame structure, but it is not limited to this.
[0038] See Figures 7 to 9 As shown, the top front side of the frame body 12 is used to detachably install the fire monitor 20; the internal cavity 14 of the frame body 12 can store the water hose 30 in an "arch"-shaped winding manner. The water outlet end of the water hose 30 is connected to the fire monitor 20, while the water inlet end of the water hose 30 can be pulled out from the rear side of the opening 141.
[0039] Therefore, in this embodiment, when there is a lack of fire hydrants near the fire point, water hoses 30 can be laid by the transport vehicle 10 to achieve remote water supply. At the same time, fire monitors 20 can be directly installed on the vehicle frame 12 to achieve remote fire extinguishing.
[0040] Specifically, the fire monitor 20 adopts an existing structure. When in use, it can be tied to the front top of the frame body 12 with wire or the like. Then, the firefighter can connect the water inlet of the hose 30 to the fire hydrant in advance, and then remotely control the transport vehicle 10 to move to the vicinity of the fire point. As the transport vehicle 10 moves forward, the hose 30, which is wound in an "arch" shape, can be continuously pulled out from the rear side of the opening 141, thereby realizing the automatic laying of the hose 30. After reaching the fire point, the fire hydrant is opened to supply water to the hose 30, and the fire monitor 20 can spray water to extinguish the fire. The firefighter can remotely control the transport vehicle 10 to adjust the spray direction of the fire monitor 20, making the firefighting process safer and more reliable.
[0041] In this embodiment, a guide roller 17 may be provided on the rear side of the opening 141 of the frame body 12. The water hose 30 can be conveyed backward via the guide roller 17 so that the water hose 30 will not get stuck when it is pulled out.
[0042] Specifically, such as Figure 2 In this embodiment, the front and rear ends of the left and right bottom sides of the frame body 12 respectively protrude outwards, forming hinge portions 121 located above the chassis 11; the flip cover 13 may be "L" shaped, including a lower frame 131 and a side frame 132 that are perpendicularly connected to each other; the lower side of the lower frame 131 is located between the two hinge portions 121, and the front and rear ends of the lower side of the lower frame 131 are respectively hinged to the two hinge portions 121; when the flip cover 13 is unfolded, the lower frame 131 is placed above the chassis 11, and the side frame 132 is spaced apart from the frame body 12, and the side of the frame body 12, the lower frame 131, and the side frame 132 form the side receiving groove 15; when the flip cover 13 is folded, the lower frame 131 is attached to the side of the frame body 12, and the side frame 132 is attached to the top surface of the frame body 12. The side compartment 15 can be used to place the fire monitor 20 and the rolled-up water hose 30 after the firefighting mission is over, and they are easy to access.
[0043] Furthermore, the upper front and rear ends of the left and right sides of the frame body 12 are respectively connected to the front and rear ends of the side frame 132 on the side away from the lower frame 131 via connecting ropes or chains 18. This allows for the limitation of the side compartment 15 in the front-rear direction, preventing fire-fighting equipment inside the side compartment 15 from falling out. Also, the connecting ropes or chains 18 do not affect the folding of the flap 13.
[0044] In this embodiment, the frame body 12 is a rectangular frame structure, and the top of the frame body 12 has a top frame 122; the winding bracket 16 is a rectangular frame, which forms a winding bracket 16 when unfolded. The winding bracket 16 includes two horizontal bars 161 and two vertical bars 162, which are spaced apart from each other on the left and right sides, and the lower ends of the two vertical bars 162 are respectively hinged to the left and right inner walls of the top frame 122; the two horizontal bars 161 are respectively connected to the two vertical bars at intervals. The upper and lower ends of 162; the overlapping bracket 21 of the hose reel 2 includes an overlapping horizontal bar 211 and an overlapping vertical bar 212. The overlapping vertical bar 212 can be placed on the middle of the two horizontal bars 161 of the unfolded reel bracket 16, and the two ends of the overlapping vertical bar 212 extend toward the reel bracket 16 respectively with a snap-fit part 213. The snap-fit part 213 is used to snap and fasten to the outside of the two horizontal bars 161. Thus, the overlapping bracket 21 can be conveniently and quickly fastened to the reel bracket 16.
[0045] The electric rewinder 22 and the overlapping crossbar 211 are spaced apart and located on the same side of the overlapping longitudinal bar 212. The overlapping crossbar 211 is connected to the lower end of the overlapping longitudinal bar 212, and its other end extends laterally beyond the hose reel 221 of the electric rewinder 22, with its end extending away from the rewinding bracket 16 to form a limiting part 214. By setting the overlapping crossbar 211 and the limiting part 214, a certain limiting and guiding function can be provided when the hose reel 221 rewinds the hose 30. The hose 30 can slide on the upper side of the overlapping crossbar 211 and the inner side of the limiting part 214.
[0046] In this embodiment, see Figure 6 The overlapping longitudinal bar 212 can be detachably fastened to the middle of the two crossbars 161 by means of the snap fastening assembly 5. The snap fastening assembly 5 may include a male snap fastener 51 provided on the crossbar 161 and a female snap fastener 52 provided on the overlapping longitudinal bar 212. The specific structure can refer to the prior art to facilitate the quick and easy cooperation and fixation of the overlapping bracket 21 and the winding bracket 16.
[0047] In this embodiment, the electric rewinder 22 includes a body 222 and a hose rewinding shaft 221 connected to the body 222; one end of the body 222 is connected to the overlapping longitudinal bar 212, and the other end is movably overlapped on one of the crossbars 161 of the rewinding bracket 16. This can improve the stability of the electric rewinder 22 during use and ensure the smooth winding of the hose 30.
