If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Understandably, referring to Figures 1 to 6The present invention relates to a lifting and folding transport vehicle, comprising two support frames 100, two scissor mechanisms 200, and a first support member 300. The two support frames 100 are arranged at intervals, and each support frame 100 has a telescopic support leg 130 on both sides. The telescopic support leg 130 can extend and retract in the vertical direction, and a support wheel 110 is rotatably connected to the lower end of the telescopic support leg 130. The scissor mechanisms 200 are connected to the two support frames 100, and the two scissor mechanisms 200 are respectively arranged on both sides of the support frame 100. The scissor mechanism 200 includes multiple scissor units 210 connected in sequence. 10 includes a first link 211 and a second link 212. The first link 211 and the second link 212 are hinged together, and the first link 211 of the preceding scissor unit 210 is hinged to the second link 212 of the following scissor unit 210. Multiple scissor units 210 cooperate to adjust the distance between the two support frames 100. One end of the first support member 300 is fixedly connected to one support frame 100, and the other end of the first support member 300 is movably connected to another support frame 100. The first support member 300, the two support frames 100 and the two scissor mechanisms 200 can form a storage space 310.

[0033] The scissor mechanism 200 is connected to two support frames 100 at both ends, and the two scissor mechanisms 200 are respectively arranged on both sides of the support frame 100. The scissor mechanism 200 includes multiple scissor units 210 connected in sequence. The scissor unit 210 includes a first link 211 and a second link 212. By setting the first link 211 and the second link 212 to be hinged, and the first link 211 of the previous scissor unit 210 to be hinged to the second link 212 of the next scissor unit 210, the multiple scissor units 210 can be extended or folded synchronously, thereby adjusting the spacing of the support frames 100. One end of the first support member 300 is fixedly connected to the support frame 100, and the other end of the first support member 300 is movably connected to another support frame 100, so that the two support frames 100 and the two scissor mechanisms 200 form a storage space 310 to facilitate the accommodation of rescue tools.

[0034] Telescopic outriggers 130 on both sides of the support frame 100 drive the scissor mechanism 200 to move up and down, facilitating the transfer of rescue tools stored high up on the fire truck to the first support member 300. This also allows for easy lifting and lowering of rescue tools at the rescue site, improving the flexibility of tool transport and reducing the workload of handling. The lower ends of the telescopic outriggers are rotatably connected to support wheels 110, enabling rapid transport of rescue tools, reducing workload, and improving transport efficiency. Furthermore, the scissor mechanism 200 can be folded and stored conveniently inside the fire truck, further enhancing rescue efficiency.

[0035] It should be noted that the upper end of the scissor mechanism 200 is a fixed end, and the lower end is a movable end. Specifically, the first link 211 and the second link 212 of the scissor unit 210 at the first end are hinged to the support frame 100, with the second link 212 slidingly connected to the support frame 100 in the vertical direction. Similarly, the first link 211 and the second link 212 of the scissor unit 210 at the last end are hinged to the support frame 100, with the first link 211 slidingly connected to the support frame 100 in the vertical direction. When the scissor mechanism 200 unfolds or folds, the first support member 300 can rise or fall synchronously, thereby enabling the rescue tool to be raised and lowered, improving ease of use and reducing the workload of handling.

[0036] One end of the first support member 300 is fixedly connected to a support frame 100, and the other end is movably connected to another support frame 100, so that the length of the first support member 300 can be adapted to the length adjustment of the scissor mechanism 200, thereby facilitating the placement of rescue tools and improving ease of use.

[0037] In addition, the first support member 300 can be made of fabric, steel mesh, etc., and is not limited here.

[0038] Reference Figure 1 When multiple scissor lift units 210 are folded, the lifting folding transport vehicle is in a folded state, which can shorten the distance between the two support frames 100, allowing the lifting folding transport vehicle to be folded and stored, reducing space occupation and making it easy to store in the fire truck.

[0039] Reference Figure 2 When multiple scissor lift units 210 are deployed, the lifting and folding transport vehicle is in a fenced-off state, which allows the two support frames 100 to be separated from each other, so that the first support member 300, the two support frames 100 and the two scissor lift mechanisms 200 can form a storage space 310, which is convenient for accommodating fire-fighting tools, preventing them from falling during transportation, and improving reliability.

[0040] Reference Figure 3 When multiple scissor units 210 continue to unfold, the lifting and folding transport vehicle is in a flat state, which allows the two scissor mechanisms 200 to be folded into a plate shape, enabling them to support tools with a length greater than the length of the lifting and folding transport vehicle, avoiding the spacing limitations of the two support frames 100, and improving the flexibility of transportation.

[0041] Understandably, referring to Figures 1 to 4The first support member 300 is provided with at least three connecting sleeves 320, two of which are equipped with connecting rods 330. The connecting rods 330 are engaged between the support frame 100 and the scissor mechanism 200. By providing at least three connecting sleeves 320 and installing two connecting rods 330 in each sleeve, and engaging them between the support frame 100 and the scissor mechanism 200, the first support member 300 can be stably positioned between the two support frames 100, reducing the possibility of the first support member 300 loosening and falling, and improving the reliability of transportation.

[0042] It should be noted that a gap is provided between the support frame 100 and the scissor mechanism 200, with the first support member 300 passing through the gap, and the connecting rod 330 being engaged at the ends of the support frame 100 and the scissor mechanism 200. When a rescue tool is placed on the first support member 300, the weight of the rescue tool can deform the first support member 300, allowing the connecting rod 330 to move closer to the support frame 100 and the scissor mechanism 200, thereby ensuring the stability of the connecting rod 330 and improving the reliability of the support.

[0043] Specifically, the number of connecting sleeves 320 and connecting rods 330 is set to three. The three connecting sleeves 320 are connected to the first support member 300 in sequence. Two of the connecting sleeves 320 are located at both ends of the first support member 300. The connecting sleeves 320 at both ends are fixedly connected to the connecting rods 330. The connecting sleeve 320 in the middle is detachably connected to the connecting rods 330.

[0044] Reference Figure 2 When the connecting sleeve 320 at the end and the connecting sleeve 320 in the middle are connected to the connecting rod 330, and both connecting rods 330 are engaged between the support frame 100 and the scissor mechanism 200, the lifting and folding transport vehicle can be stabilized in the fence state.

[0045] Reference Figure 3 When the connecting sleeves 320 at both ends are connected to the connecting rods 330, and both connecting rods 330 are engaged between the support frame 100 and the scissor mechanism 200, the lifting and folding transport vehicle can be stabilized in a flatbed state.

[0046] By assembling and disassembling the connecting rod 330 located in the intermediate connecting sleeve 320, the lifting and folding transport vehicle can be easily adjusted between the fenced state and the flatbed state, and the state of the lifting and folding transport vehicle can be stably maintained, thus improving reliability.

[0047] Understandably, referring to Figure 2 and Figure 5Multiple support rods 213 are connected between the two scissor lift mechanisms 200. These support rods 213 are spaced apart, and the first support member 300 is positioned on these support rods 213. By connecting multiple spaced support rods 213 between the two scissor lift mechanisms 200 and positioning the first support member 300 on these support rods 213, the weight of the first support member 300 and the rescue tools it carries can be distributed, preventing structural deformation or damage caused by excessive localized stress. This allows the lifting and folding transport vehicle to better withstand the pressure of heavy objects during transport, ensuring transport safety.

[0048] Understandably, referring to Figure 2 and Figure 6 The support frame 100 is also provided with a second support member 120, and two telescopic outriggers 130 are connected to both ends of the second support member 120. The second support member 120 connects to the two telescopic outriggers 130 so that the first support member 300, the second support member 120 and the two scissor mechanisms 200 can form a storage space 310, which can conveniently accommodate rescue tools, reduce the possibility of falling, and improve the reliability of transportation.

[0049] The second support component 120 can also be made of fabric, steel mesh, etc., which can reduce the overall weight of the lifting and folding transport vehicle, facilitate storage and handling, and improve the convenience of use.

[0050] Specifically, refer to Figure 3 and Figure 7 The telescopic outrigger 130 includes multiple support rods 131, which are sequentially nested together, with adjacent support rods 131 being slidably connected. The telescopic outrigger 130 is configured with multiple sequentially nested support rods 131, and this sliding structure allows for multi-stage telescopic extension and retraction, increasing the range of height adjustment, better adapting to the lifting and transport of rescue tools, and improving its flexibility of use.

[0051] Specifically, refer to Figure 7 The telescopic outrigger 130 is equipped with a quick-connect connector 132, which allows it to connect to the air supply of the fire truck. This quick-connect connector 132 enables rapid connection between the telescopic outrigger 130 and the fire truck's air supply, allowing the outrigger 130 to be quickly adjusted in height using the power provided by the air supply. This, in turn, raises and lowers the first support member 300 and the scissor mechanism 200, quickly positioning the rescue equipment for timely deployment in rescue operations. This not only improves the response speed of rescue operations but also reduces the operational difficulty and labor intensity for firefighters, making rescue operations more efficient.

[0052] It should be noted that, referring to Figure 8Each telescopic outrigger 130 has a throttle valve connected to both its air inlet and outlet. The fire truck's air supply is connected to the telescopic outrigger 130 via a manual three-position four-way valve. With the cooperation of multiple throttle valves, multiple telescopic outriggers 130 can be raised and lowered synchronously, thereby enabling the first support component 300 to be raised and lowered smoothly and improving the stability of transportation.

[0053] Understandably, referring to Figure 7 A steering seat 140 is rotatably connected to the lower end of the support frame 100, and a support wheel 110 is rotatably connected to the steering seat 140. The rotation axis of the steering seat 140 is perpendicular to the rotation axis of the support wheel 110. By providing a rotatably connected steering seat 140 at the lower end of the support frame 100 and rotatably connecting the support wheel 110 to the steering seat 140, with the rotation axis of the steering seat 140 perpendicular to the rotation axis of the support wheel 110, the maneuverability and flexibility of the lifting and folding transport vehicle are improved. This allows the support wheel 110 to achieve flexible steering in all directions, reduces the turning radius of the transport vehicle, and helps to improve transportation efficiency.

[0054] Understandably, referring to Figure 1 The first support component 300 is made of Oxford cloth. By using Oxford cloth for the first support component 300, the structural strength of the first support component 300 can be improved, the possibility of damage can be reduced, the service life of the first support component 300 can be effectively extended, and maintenance costs can be reduced. It not only facilitates the folding and storage of the first support component 300, but also does not excessively increase the overall weight of the transport vehicle, making it easier for firefighters to move and operate the transport vehicle, thus improving the portability and flexibility of the transport vehicle.

[0055] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
