Description

Technical Field

[0001] This invention relates to the field of public safety technology, and in particular to a foldable fire truck-specific equipment transport vehicle. Background Technology

[0002] At present, the storage, transportation, on-site operation and transfer system of fire trucks and equipment still follows the traditional operation mode. The supporting auxiliary technologies and standardized tooling facilities are not perfect, which cannot adapt to the needs of rapid response to complex emergency rescue. This results in obvious efficiency shortcomings in the whole process of vehicle disembarkation and standby, equipment transfer and equipment classification.

[0003] Currently, most fire truck equipment compartments are general-purpose enclosed structures, which cannot achieve modular zoning and classified storage. Various protective equipment, demolition tools, and air supply equipment are mixed and stacked together, and there is no visual quick access mechanism. As a result, time is spent searching for matching equipment, which greatly increases the preparation time for equipment retrieval and thus significantly prolongs the preparation time and affects the efficiency of rescue.

[0004] Furthermore, the equipment compartments, disembarkation passages, and work areas of typical fire trucks are concentrated on one side of the vehicle. Multiple firefighters from different shifts are concentrated on one side of the vehicle to carry out unloading and donning operations. The doors, equipment deployment areas, and disembarkation passages overlap, and some people are getting equipment, some are putting on protective clothing, and some are carrying large equipment, which blocks each other's way and creates traffic congestion. This means that when multiple processes such as equipment unloading, donning protective clothing, and moving equipment are carried out simultaneously, the traffic flow is intersecting and personnel are congested. As a result, the team cannot form a parallel and collaborative work system, and the team's work efficiency is difficult to improve, which affects the rescue efficiency.

[0005] Furthermore, in terms of equipment transportation, fire trucks generally lack lightweight auxiliary transportation facilities such as vehicle-mounted rails, roller brackets, and portable assistive devices. Heavy rescue equipment lacks mechanized transportation technology support. Loading fire equipment onto fire trucks and transporting it to the fire scene relies entirely on manual handling, resulting in high manpower consumption, low transportation speed, and severely impacting the initial emergency response rhythm. In particular, there are shortcomings in the technology adapted to some complex rescue scenarios. Faced with narrow alleys, road congestion, and on-site obstacles, fire trucks cannot reach the core rescue operation area, creating a long distance between the fire truck and the accident scene. Due to the lack of small-scale transportation equipment, fire equipment must be manually transported back and forth over long distances. This not only consumes a significant amount of time, squeezing out the golden window of opportunity for rescue and delaying the operation, but also requires manual return trips to the fire truck for replacement if fire equipment malfunctions, further delaying the rescue due to the extended travel time. Summary of the Invention

[0006] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a foldable fire truck-specific equipment transport vehicle. This vehicle uses multiple partitions connected to the top of the base plate to form multiple separated storage areas in different directions, thereby achieving not only the purpose of classified storage but also facilitating the formation of a parallel collaborative work system within the team. Front and rear wheels are respectively installed at the front and rear of the base plate, with wheels connected to the underside of the front and rear outriggers. This allows the transport vehicle to be directly pushed to the core rescue location via the wheels under the outriggers and rear outriggers, resulting in fast transport speed, reduced manpower consumption, and improved rescue efficiency.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A foldable fire truck equipment transfer vehicle includes a floor, front and rear outriggers rotatably connected to the floor, front and rear wheels spaced apart from each other, and multiple partitions connected to the floor. The partitions and the floor together form multiple separated storage areas. The front and rear outriggers are spaced apart, and wheels are connected to the bottom of both the front and rear outriggers.

[0009] Preferably, the multiple partitions include a main compartment transverse partition 51, a main compartment longitudinal partition 52, and multiple partition transverse partitions 53. The main compartment transverse partition 51 extends horizontally and is connected to the rear side above the bottom plate. The main compartment longitudinal partition 52 extends front-back and its rear end abuts against the main compartment transverse partition 51. The partition transverse partitions 53 also extend horizontally and are located at intervals behind the main compartment transverse partition 51. Each partition transverse partition 53 is located either to the left or to the right of the main compartment longitudinal partition 52.

[0010] Preferably, the partition 53 is detachably connected to the base plate.

[0011] Preferably, the rearward side of the main compartment partition 51 is provided with two rows of strap installation joints, and each row is provided with multiple sets of strap installation joints. Each set of strap installation joints includes two strap installation joints spaced apart from each other. Each set of strap installation joints is connected to a strap, and at least one of the strap installation joints in each set is configured to be detachably connected to the corresponding side of the strap.

[0012] Preferably, a first handle is provided at both ends of the main compartment partition 51 and at the end of the partition partition 53 opposite to the main compartment longitudinal partition 52.

[0013] Preferably, two front support legs are spaced apart on the left and right, and a first front crossbar connects the two front support legs; two rear support legs are also spaced apart on the left and right, and a first rear crossbar connects the two rear support legs; a first locking mechanism is provided between each front support leg, rear support leg and base plate to limit their relative rotation with respect to the base plate; an unlocking mechanism connected to the first locking mechanism and used to unlock the first locking mechanism is also provided on the base plate; after the first locking mechanism is unlocked by the unlocking mechanism, the front support legs and rear support legs can rotate relative to the base plate.

[0014] Preferably, the rear support leg includes an upper support member and a lower support member, the upper side of the upper support member is rotatably connected to the base plate, and the lower side is rotatably connected to the upper side of the lower support member; a second locking mechanism for limiting the relative rotation of the two is provided between the lower side of the upper support member and the upper side of the lower support member, and the unlocking mechanism is further configured to be connected to the second locking mechanism and to unlock the second locking mechanism.

[0015] Preferably, the transfer vehicle further includes a front inclined support leg and a rear inclined support leg. The front inclined support leg includes a first upper support member and a first lower support member. The upper side of the first upper support member is rotatably connected to the base plate, and the lower side is rotatably connected to the upper side of the first lower support member. The lower side of the first lower support member is rotatably connected to the first front crossbar, and the connection position between the upper side of the first upper support member and the base plate is located behind the connection position between the upper side of the front support leg and the base plate. The rear inclined support leg includes a second upper support member and a second lower support member. The upper side of the second upper support member is rotatably connected to the base plate, and the lower side is rotatably connected to the upper side of the second lower support member. The lower side of the second lower support member is rotatably connected to the first rear crossbar, and the connection position between the upper side of the second upper support member and the base plate is located behind the connection position between the upper side of the second support leg and the base plate.

[0016] Preferably, a third locking mechanism for restricting the rotation of the first upper support member and the second upper support member relative to the base plate is provided between the upper side of the first upper support member and the upper side of the first lower support member, and a fourth locking mechanism for restricting the relative rotation of the two members is provided between the lower side of the first upper support member and the upper side of the first lower support member, and a fourth locking mechanism for restricting the relative rotation of the two members is also provided between the lower side of the second upper support member and the upper side of the second lower support member. The unlocking mechanism is further configured to be connected to the third locking mechanism and the fourth locking mechanism and to unlock the third locking mechanism and the fourth locking mechanism.

[0017] Preferably, the locking mechanism is provided with two sets, left and right, one set for unlocking the first, second, third and fourth locking mechanisms on the left, and the other set for unlocking the first, second, third and fourth locking mechanisms on the right.

[0018] Because the present invention adopts the above technical solution, it has the following beneficial effects:

[0019] 1. The transport vehicle of this invention can be switched between an unfolded state and a folded state. In the unfolded state, the front and rear outriggers are vertically supported under the base plate, and the transport vehicle can be moved by the wheels; in the folded state, the front and rear outriggers can rotate relative to the base plate and move closer to the base plate, and the transport vehicle is supported and moved by the front and rear wheels on the base plate. Compared with the unfolded state, the overall height of the folded transport vehicle is greatly reduced, making it convenient to place in the trunk of a fire truck.

[0020] 2. The multiple partitions and the base plate together form multiple separated storage areas in different directions, thereby achieving the purpose of modular partitioning and classified storage. The fire-fighting items in different storage areas are clearly visible, and firefighters only need to take the fire-fighting items they need from the corresponding storage area. In this way, not only is there no need to waste time searching for equipment, but also because multiple storage areas are in different directions, multiple people can take equipment from different directions and move it away after taking it. That is, multiple people and multiple processes can be carried out in an orderly and simultaneous manner, realizing a team parallel collaborative operation system, avoiding the overlap of multiple people's work space, causing personnel movement intersections and personnel congestion, thereby improving team operation efficiency and rescue efficiency.

[0021] 3. Front and rear wheels are installed on the underside of the base plate, so that when pushing the transfer vehicle into the trunk of the fire truck or pulling it out of the trunk of the fire truck, the operation can be made easy and effortless by rotating the front and rear wheels.

[0022] 4. Because wheels are installed under the front and rear outriggers, even if the fire truck cannot reach the core rescue location, the transport vehicle fully loaded with firefighting equipment can be pulled out of the fire truck's trunk and pushed directly to the core rescue location by the wheels under the outriggers. Compared to manually carrying equipment back and forth, this not only allows for faster equipment transport and avoids delays in rescue time, but also avoids the physical exhaustion caused by multiple trips by hand, allowing firefighters to conserve their energy for rescue. Furthermore, even if firefighting equipment malfunctions, it can be replaced directly from the transport vehicle without having to make a second trip to the fire truck, thus avoiding wasted time and improving rescue efficiency.

[0035] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0036] like Figures 1 to 6 As shown, the present invention discloses a foldable fire truck special equipment transfer vehicle 100, which includes a base plate 1, front outriggers 2 and rear outriggers 3 rotatably connected to the lower part of the base plate 1, front wheels 101 and rear wheels 102 connected to the lower part of the base plate 1 at intervals, and multiple partitions 5 connected to the upper part of the base plate 1. The multiple partitions and the base plate 1 together form multiple separated storage areas. The front outriggers 2 and rear outriggers 3 are arranged at intervals, and wheels 20 are connected to the bottom of the front outriggers 2 and rear outriggers 3.

[0037] The transport vehicle 100 of the present invention adopts the above-described configuration, thereby enabling it to switch between an unfolded state and a folded state. In the unfolded state, the front support leg 2 and the rear support leg 3 are vertically supported below the base plate 1, and the transport vehicle can be moved by the wheels 20. When folded, the front support leg 2 and the rear support leg 3 can rotate relative to the base plate 1 and move closer to the base plate 1. The transport vehicle is supported and moved by the front wheel 101 and the rear wheel 102 on the base plate 1. Compared with the unfolded state, the overall height of the folded transport vehicle is greatly reduced, making it convenient to place in the trunk of a fire truck.

[0038] In this embodiment, two front support legs 2 are spaced apart on the left and right, and a first front crossbar 21 connects the two front support legs 2; two rear support legs 3 are also spaced apart on the left and right, and a first rear crossbar 31 connects the two rear support legs 3. With this arrangement, the two front support legs 2 and the two rear support legs 3 can stably support the transport vehicle of the present invention in the unfolded state; moreover, when folded, the two front support legs 2 can rotate synchronously relative to the base plate 1, and the two rear support legs 3 can also rotate synchronously relative to the base plate 1.

[0039] The wheels 20 at the bottom of the front outrigger 2 and the rear outrigger 3 are both configured as omnidirectional wheels, which facilitates movement within the transport vehicle of this invention. The front wheel 101 and the rear wheel 102 can be configured as directional wheels, i.e., directional wheels that can only rotate forward and backward, or as omnidirectional wheels. The tires of the wheels 20, the front wheel 101, and the rear wheel 102 can be anti-skid tires, thereby better adapting to more road conditions. In this embodiment, the front wheel 101 is located on the front side of the front outrigger 2, and the rear wheel 102 is located on the rear side of the rear outrigger 3.

[0040] Preferably, each of the wheels 20, front wheel 101, and rear wheel 102 is equipped with a foot-operated braking mechanism. When the transport vehicle does not need to be moved, the foot-operated braking mechanism can be depressed. The use of foot-operated braking mechanisms on the wheels is conventional technology, and the braking and releasing operations are also conventional, so they will not be described in detail here.

[0041] In this embodiment, the multiple partitions include a main compartment horizontal partition 51, a main compartment longitudinal partition 52, and multiple partition horizontal partitions 53. The main compartment horizontal partition 51 extends horizontally and is connected to the rear side above the bottom plate 1. The main compartment longitudinal partition 52 extends front-back and its rear end abuts against the main compartment horizontal partition 51. The partition horizontal partitions 53 also extend horizontally and are located at intervals behind the main compartment horizontal partition 51. Each partition horizontal partition 53 is located either to the left or to the right of the main compartment longitudinal partition 52. With this configuration, the portion of the base plate 1 located behind the main compartment partition 51 forms a storage area together with the main compartment partition 51. The main compartment partition 51, adjacent section partitions 53, main compartment longitudinal partition 52, and corresponding portions of the base plate 1 form another storage area. Any two section partitions 53 located on the same side of the main compartment longitudinal partition 52, along with corresponding portions of the main compartment longitudinal partition 52 and the base plate 1, form another storage area. The last section partition 53, along with corresponding portions of the main compartment longitudinal partition 52 and the base plate 1, forms another storage area. In this way, the partitions divide the space above the base plate 1 into multiple storage areas. Each storage area can hold the same fire-fighting equipment or the same type of fire-fighting equipment, i.e., zoned planning and placement of fire-fighting equipment.

[0042] Preferably, the partition partitions 53 are detachably connected to the base plate 1. This allows for the installation of different numbers of partition partitions 53 on the left and right sides of the main compartment partition 52, and adjustment of the distance between adjacent partition partitions 53, according to actual needs. For example, on one side of the main compartment partition 52, no partition partition 53 may be installed, while one or more partition partitions 53 may be installed on the other side; alternatively, one or more partition partitions 53 may be installed on both sides of the main compartment partition 52, and the number of partitions and the spacing between adjacent partitions can be increased or decreased according to actual needs. This arrangement allows the invention to adjust the size of the storage area according to the size of different equipment, making it more suitable for the partitioned placement of fire-fighting equipment of different sizes.

[0043] The detachable connection between each partition and the base plate 1 can be achieved by screws that lock the base plate 1 to each partition from the bottom to the top. When it is necessary to remove the partition 53 at a set position, simply unscrew the corresponding screws to remove the corresponding partition 53 from the base plate 1.

[0044] Furthermore, the main compartment transverse partition 51 and main compartment longitudinal partition 52 are also detachably connected to the base plate 1. With this configuration, when not in use, the partitions can be removed from the base plate 1 and stacked on the base plate 1 after the transfer cart is folded, thus making the overall size of the transfer cart smaller and requiring less space.

[0045] Preferably, the upper surface of the base plate 1 is provided with multiple transverse and longitudinal positioning grooves 11, which allow the lower ends of the partitions to be placed within them. Thus, when installing the main compartment transverse partitions 51, the main compartment longitudinal partitions 52, and multiple partition transverse partitions 53, the lower ends of each partition can be placed in the corresponding grooves and then secured with screws. This allows for faster and better installation of the partitions.

[0046] Furthermore, the main compartment longitudinal partition 52 is also interconnected with the tops of the partition transverse partitions 53 and 51. In one embodiment, the tops of the main compartment longitudinal partition 52, partition transverse partitions 53, and 51 are provided with ball-and-socket fastening devices 50. After each partition is screwed to the bottom plate 1, the tops of the main compartment longitudinal partition 52, partition transverse partitions 53, and 51 are connected by these ball-and-socket fastening devices 50. The structure and connection principle of the ball-and-socket fastening device are conventional technologies and are not innovative points of this invention, so they will not be described in detail here. In another embodiment, a fixing plate can be directly installed on the top of the main compartment longitudinal partition 52, the partition transverse partition 53, and the main compartment transverse partition 51. After each partition is locked to the bottom plate 1, the fixing plate at the corresponding position is connected and locked to the partition transverse partition 53, the main compartment longitudinal partition 52, or the main compartment transverse partition 51 and the main compartment longitudinal partition 52 from top to bottom using screws, thereby locking the partition transverse partition 53, the main compartment transverse partition 51, and the corresponding main compartment longitudinal partition 52. As described above, the partitions are more stable after installation.

[0047] Preferably, the rearward side of the main compartment partition 51 is provided with two rows of strap installation connectors 511, and each row is provided with multiple sets of strap installation connectors 511. Each set of strap installation connectors 511 includes two strap installation connectors 511 spaced apart. Each set of strap installation connectors 511 is connected to a strap 512, and at least one of the strap installation connectors 511 in each set is configured to be detachably connected to the corresponding side of the strap 512. The mechanism of the strap 512 and the strap installation connectors 511 and the detachable connection can be any known and feasible mechanism. For example, the set of strap installation connectors 511 can be respectively configured as male and female buckles of a fastener. Correspondingly, the two ends of the strap are respectively connected to female and male buckles. The detachable connection between the strap and the strap installation connectors 511 is achieved through the detachable connection of the male and female buckles (the attached drawings are only simplified and do not affect the understanding of those skilled in the art). Furthermore, after the two ends of the strap 512 are respectively connected to female and male buckles, the length of the strap is adjustable. The connection between the main compartment partition 51 and the male and female buckles can be any known and feasible method, such as using two short webbings to be conventionally connected to the female and male buckles respectively, and then fixing the other end of the webbing to the main compartment partition 51 with screws or other conventional methods. The connection of the two ends of the strap to the male and female buckles and the adjustable length of the strap are conventional techniques, so they will not be described in detail here.

[0048] The main compartment partition 51 is equipped with the aforementioned straps 512 and strap mounting connectors 511, allowing the self-contained breathing apparatus to be vertically placed within the storage area formed by the rear side of the main compartment partition 51 and the main compartment partition 51. Specifically, first, disconnect one end of each of the upper and lower straps from the strap mounting connector 511, then place the self-contained breathing apparatus in the corresponding position, and then connect one end of each strap to the corresponding strap mounting connector 511. In this way, the upper and lower straps secure the self-contained breathing apparatus to the main compartment partition 51. Furthermore, the strap length is adjustable, allowing for a more secure fastening of the self-contained breathing apparatus.

[0049] Preferably, a first handle 54 is provided at both ends of the main compartment partition 51 and at the end of the partition partition 53 opposite to the main compartment longitudinal partition 52. The first handle 54 can be U-shaped. With the first handle 54 provided, after fire-fighting equipment is placed in the storage area between adjacent partitions in the front-to-back direction, both ends of a rope can be tied to the first handle 54 on the adjacent partition, thereby preventing the fire-fighting equipment from falling out of the storage area. Alternatively, one end of the rope can be tied to the first handle 54 on a partition, and the other end can be tied to a hook, which can hook onto the U-shaped first handle 54 of the adjacent partition. Furthermore, the first handle 54 facilitates the installation and removal of the partition by hand.

[0050] In other embodiments, all partitions are detachably connected to the base plate 1, so that firefighters can select different numbers of partitions to arrange and connect in different directions on the base plate 1 according to actual needs, thereby forming storage areas of different numbers, sizes and positions, which will not be listed here.

[0051] In this embodiment, preferably, second handles 12 are provided on the front and rear sides and / or the left and right sides of the base plate 1. These handles can be U-shaped members protruding outwards from the end faces of the front and rear sides and / or the left and right sides of the base plate 1, forming the second handles 12. The second handles 12 can also have other feasible shapes, as long as they are suitable for gripping. The provision of the second handles 12 facilitates multiple people lifting the transport vehicle 100, enabling multiple people to lift the transport vehicle like a stretcher in complex terrain with obstacles or other locations where movement by the wheels 20 is impossible, and transport it to the rescue location to carry out rescue operations. This diversifies the movement methods of the transport vehicle equipped with this invention and broadens its adaptability.

[0052] Each of the front support leg 2 and rear support leg 3 is provided with a first locking mechanism between itself and the base plate 1 to restrict their relative rotation with respect to the base plate 1. The base plate 1 is also provided with an unlocking mechanism connected to the first locking mechanism and used to unlock it. After the first locking mechanism is unlocked, the front support leg 2 and rear support leg 3 can rotate relative to the base plate 1. The specific mechanisms of the first locking mechanism and the unlocking mechanism can be any known and feasible mechanisms, as long as they can achieve the corresponding functions; they are not the inventive point of this invention.

[0053] Combination Figure 8 , 9 As shown, taking the front outrigger 2 as an example, a first pivot seat 13 protrudes downward from the lower end face of the base plate 1, and a second pivot seat 22 is provided at the upper end of the front outrigger 2. The first pivot seat 13 and the second pivot seat 22 are pivotally connected, thereby achieving the purpose of relatively rotatable connection between the front outrigger 2 and the base plate 1. The first locking mechanism includes a first tooth groove 131 and a second tooth groove 221 respectively disposed on opposite sides of the first pivot seat 13 and the second pivot seat 22, a gear 61 relatively movable in the first tooth groove 131 and the second tooth groove 221, and a compression spring 62 disposed between the gear 61 and the bottom wall of the first tooth groove 131. Under the action of the compression spring 62, the gear 61 moves away from the compression spring 62 and simultaneously meshes with the first tooth groove 131 and the second tooth groove 221, and the first locking mechanism is in a locked state, so that the front outrigger 2 cannot rotate relative to the base plate 1.

[0054] The unlocking mechanism includes an operating component 71 that is movably connected to the base plate 1, a first traction rope (not shown) connected to the operating component at one end, and a driving component 72 connected to the other end of the first traction rope. The driving component 72 is rotatable and movable within the second tooth groove 221, and the driving component 72 and the compression spring 62 are located on two different sides of the gear 61. The side wall of the second tooth groove 221 is provided with a through hole (not shown) for the other end of the first traction rope to extend into. The other end of the first traction rope extends into the second tooth groove 221 through the through hole and connects with the driving component 72. The bottom wall of the second tooth groove 221 and the opposite side of the driving component 72 are respectively provided with a boss 222 and a groove 721. The boss 222 extends into the groove 721, and the end face of the boss 222 and the bottom wall of the groove 721 are respectively provided as a cooperating active inclined surface 223 and a driven inclined surface 722. When the first locking mechanism is to be unlocked, the driving member 72 is driven to move relative to the base plate 1, thereby pulling the first traction cable. The first traction cable pulls the driving member 72 to rotate. With the cooperation of the active inclined plane and the driven inclined plane, the driving member 72 moves towards the gear 61 at the same time, thereby pushing the gear 61 to move towards the first tooth groove 131, until the gear 61 disengages from the second tooth groove 221 and only engages with the first tooth groove 131. The first locking mechanism is unlocked, and the front support leg 2 can rotate relative to the base plate 1.

[0055] In this embodiment, the operating member 71 is movably connected to the rear end face of the base plate 1. In other embodiments, the operating member 71 may also be movably connected to the rear end face of the base plate 1. The operating member 71 may also be movably connected to the rear side of the lower end face of the base plate 1, allowing the first traction rope to be pulled by moving the operating member 71 backward. The operating member 71 may also be rotatably connected to the rear end face of the base plate 1, allowing the first traction rope to be pulled by rotating the operating member 71. The operating member 71 can be movably or rotatably connected to the base plate 1 in any known and feasible manner. Since the specific connection method is not an innovation of this invention, it will not be described in detail here.

[0056] The first locking mechanism between the rear outrigger 3 and the base plate 1 operates on the same principle as the first locking mechanism between the front outrigger 2 and the base plate 1. The unlocking mechanism is configured to unlock both the first locking mechanism between the front outrigger 2 and the base plate 1 and the first locking mechanism between the rear outrigger 3 and the base plate 1. Specifically, the number of the first traction ropes and driving components 72 is the same as the number of the first locking mechanisms. One end of each first traction rope is connected to the operating component 71, and the other end is connected to the corresponding driving component 72 located within the first locking mechanism. Thus, when the operating component 71 moves relative to the base plate 1, it pulls all the first traction ropes connected to it, thereby pulling the driving component 72 of the corresponding first locking mechanism to rotate and unlock the corresponding first locking mechanism.

[0057] In this embodiment, the rear support leg 3 includes an upper support member 32 and a lower support member 33. The upper side of the upper support member 32 is rotatably connected to the base plate 1, and the lower side is rotatably connected to the upper side of the lower support member 33. That is, a first locking mechanism is provided between the upper side of the upper support member 32 and the base plate 1. Preferably, a second locking mechanism for limiting the relative rotation of the two is provided between the lower side of the upper support member 32 and the upper side of the lower support member 33. The setting principle of the second locking mechanism is the same as that of the first locking mechanism, so it will not be described in detail here. The unlocking mechanism is also configured to be connected to the second locking mechanism and to unlock the second locking mechanism. Specifically, the drive member 72 in the first locking mechanism between the upper support member 32 and the base plate 1 is connected to one end of a second traction rope, and the other end of the second traction rope is connected to the drive member 72 in the second locking mechanism. With this configuration, when the first locking mechanism is unlocked, the drive component 72 within the first locking mechanism between the upper support member 32 and the base plate 1 is pulled and rotated, which in turn pulls the second traction rope, thereby causing the drive component 72 within the second locking mechanism to rotate and move, thus unlocking the second locking mechanism. This achieves the coordinated unlocking of the first and second locking mechanisms on the rear outrigger 3. The unlocking operation is therefore very simple.

[0058] The rear support leg 3 is configured as described above because when folding the transport vehicle of this invention, both the front support leg 2 and the rear support leg 3 rotate upwards and backwards until they are close to the base plate 1 and can no longer rotate. Since the front support leg 2 is positioned relative to the front side of the base plate 1, after folding, the front support leg 2 is located below the base plate 1 and does not protrude beyond the rear side of the base plate 1. However, the rear support leg 3 is connected relative to the rear side of the base plate 1; therefore, after folding, part of the rear support leg 3 will protrude beyond the rear side of the base plate 1, which increases the length of the folded transport vehicle, making it impossible to fit entirely inside the fire truck. The rear support leg 3 of the transport vehicle of this invention adopts the above design, and the specific lengths of the upper support member 32 and the lower support member 33 can be set according to the distance between the upper end of the upper support member 32 and the rear end of the base plate 1, and the height of the partition, so that after folding, the upper side of the lower support member 33 is approximately flush with the rear side of the base plate 1, and then the lower support member 33 can be manually rotated upwards until it can no longer rotate. In this way, the length and height of the transfer vehicle will not be increased, because the partition itself has a certain height, and the lower support 33, which rotates upward, will not be higher than the partition. In the unfolded state, the second locking mechanism is in the locked state, and the upper support 32 and the lower support 33 cannot rotate relative to each other, thus not affecting the stability of the transfer vehicle in the unfolded state.

[0059] In this embodiment, the transfer vehicle further includes a front inclined support leg 8 and a rear inclined support leg 9. The front inclined support leg 8 includes a first upper support member 81 and a first lower support member 82. The upper side of the first upper support member 81 is rotatably connected to the base plate 1, and the lower side is rotatably connected to the upper side of the first lower support member 82. The lower side of the first lower support member 82 is rotatably connected to the first front crossbar 21. The connection position between the upper side of the first upper support member 81 and the base plate 1 is located behind the connection position between the upper side of the front support leg 2 and the base plate 1. The lower side of the first lower support member 82 is rotatably sleeved on the first front crossbar 21, thereby achieving the purpose of relative rotation between the two. Similarly, the rear inclined support leg 9 includes a second upper support member 91 and a second lower support member 92. The upper side of the second upper support member 91 is rotatably connected to the base plate 1, and the lower side is rotatably connected to the upper side of the second lower support member 92. The lower side of the second lower support member 92 is rotatably connected to the first rear crossbar 31. The connection position between the upper side of the second upper support member 91 and the base plate 1 is located behind the connection position between the upper side of the two support legs and the base plate 1.

[0060] Two front inclined support legs 8 are spaced apart on the left and right sides, and a second front crossbar 83 connects the two front inclined support legs 8. The second front crossbar 83 is connected to the first upper support member 81 of the two front inclined support legs 8. The second front crossbar 83 allows the two front inclined support legs 8 to fold and unfold synchronously. Similarly, two rear inclined support legs 9 are spaced apart on the left and right sides, and a second rear crossbar 93 connects the two rear inclined support legs 9. The second rear crossbar is connected to the first upper support member 81 of the two rear inclined support legs 9.

[0061] A third locking mechanism is provided between the upper side of the first upper support member 81 and the upper side of the second upper support member 91 and the base plate 1 to restrict the rotation of the first upper support member 81 and the second upper support member 91 relative to the base plate 1. A fourth locking mechanism is provided between the lower side of the first upper support member 81 and the upper side of the first lower support member 82 to restrict their relative rotation. A fourth locking mechanism is also provided between the lower side of the second upper support member 91 and the upper side of the second lower support member 92 to restrict their relative rotation. Similarly, the unlocking mechanism is also configured to connect with the third and fourth locking mechanisms and to unlock the third and fourth locking mechanisms. Furthermore, the two sets of unlocking mechanisms unlock one side of the third and fourth locking mechanisms respectively. The setting principle and linkage unlocking principle of the third and fourth locking mechanisms are the same as those of the first and second locking mechanisms on the rear support leg 3, and therefore will not be described in detail here.

[0062] In this embodiment, the locking mechanism is provided in two sets, left and right. One set is used to unlock the first, second, third, and fourth locking mechanisms on the left side, and the other set is used to unlock the first, second, third, and fourth locking mechanisms on the right side. Therefore, to fold the transport vehicle of this invention, both sets of unlocking mechanisms' operating components 71 must be driven by hand. This design avoids accidental folding of the transport vehicle due to misoperation, thus preventing losses. In other embodiments, one unlocking mechanism can control the unlocking of all locking mechanisms, i.e., one end of each traction rope is connected to an operating component 71. However, to avoid misoperation, a safety lock device that cooperates with the operating component 71 can be provided. Taking the operating component 71, which is movably connected to the rear end face of the base plate 1, as an example, a blocking component that can move vertically relative to the base plate 1 can be provided on the side where the operating component 71 can be unlocked. When the blocking component blocks one side of the operating component 71, the operating component 71 cannot move to that side, thus preventing the unlocking of the locking mechanism. To unlock the locking mechanism, the blocking component must first be moved upwards or downwards so that it no longer blocks the operating component 71, allowing the operating component 71 to move to that side and unlock the locking mechanism. This also avoids accidental operation.

[0063] In this embodiment, preferably, to facilitate the routing of each traction rope, the lower end of the base plate 1 is connected to two routing tubes 10 on the left and right. The traction rope on the same side passes through the routing tube 10 on the opposite side. Each routing tube is provided with a through hole (not shown) at the corresponding position of the first locking mechanism and the third locking mechanism so that the corresponding traction rope can pass through and enter the corresponding locking mechanism.

[0064] The front inclined support leg 8 and the rear inclined support leg 9 are configured to provide more stable support for the transport vehicle of the present invention when it is unfolded. When folded, as the front support leg 2 rotates and moves backward and upward, the lower side of the first upper support member 81 and the upper side of the first lower support member 82 are rotated and moved upward in conjunction with it. The lower side of the first lower support member 82 is driven to rotate and move backward and upward until the front inclined support leg 8 is folded into a two-fold shape and close to the base plate 1. Similarly, as the rear support leg 3 rotates and moves backward and upward, it can drive the lower side of the second upper support member 91 and the upper side of the second lower support member 92 to rotate and move upward, so that the lower side of the second lower support member 92 rotates and moves backward and upward until the rear inclined support leg 9 is folded into a two-fold shape and close to the base plate 1.

[0065] Because the transfer vehicle of this invention employs the aforementioned mechanism, it can be folded when not in use to reduce storage space occupation, and two or more folded transfer vehicles can be stacked (e.g., Figure 10 (As shown).

[0066] When using the transport vehicle 100 of this invention, firstly, the partitions 53 are added or removed and their spacing adjusted according to the required fire-fighting equipment to set up multiple storage areas. Then, different fire-fighting equipment is placed in the appropriate storage areas, thereby achieving the purpose of modular partitioning and classified storage. Then, when the transport vehicle is in the unfolded state, it is pushed to the rear trunk opening of the fire truck 200, so that the part of the floor plate 1 located in front of the front outrigger 2 enters the trunk, and the front wheels 101 are supported on the trunk chassis. When moving the transport vehicle further into the trunk, the operating component 71 is driven to move relative to the floor plate 1 to unlock all locking mechanisms. Because the operating component 71 is located on the rear end face or the rear side of the lower end face of the floor plate 1, it is located on the opposite rear side of the floor plate 1, so the transport vehicle can be moved while unlocking the locking mechanism, making the operation more convenient. When the transfer vehicle moves to the point where its front outrigger 2 contacts the chassis of the fire truck's rear compartment, the front outrigger 2 will rotate and fold backward and upward due to the contact force, and the first upper support member 81 and the first lower support member 82 of the front inclined outrigger 8 will also fold in conjunction with it; as the transfer vehicle continues to move into the rear compartment, the front outrigger 2, the first upper support member 81 and the first lower support member 82 of the front inclined outrigger 8 will all come close to the base plate 1 (e.g., Figure 11 As shown), and because the front wheel 101 is supported by the trunk chassis, the front wheel 101 assists in the movement of the transfer vehicle, making it easy to move the transfer vehicle forward and into the trunk. When the transfer vehicle continues to move until its rear leg contacts the trunk chassis of the fire truck, the front outrigger 2 will rotate and fold backward and upward due to the contact force, and the second upper support member 91 and the second lower support member 92 of the rear inclined outrigger 9 will also fold, until the transfer vehicle is completely inside the trunk of the fire truck. The second upper support member 91, the second lower support member 92, and the rear outrigger 3 are all close to the base plate 1, and the rear wheel 102 is also supported by the trunk chassis. Then the lower support member 33 of the front outrigger 2 is rotated upward until it can no longer rotate (as shown).Figure 12 As shown), at this time, the drive of the operating component 71 can be released (after the operating component 71 is released, under the action of the compression elasticity, the gear 61 moves towards the direction of the second tooth groove 221 and pushes the driving component 72 to move. Through the mutual cooperation of the active inclined plane and the driven inclined plane, the driving component 72 rotates in the opposite direction, thereby pulling the first traction rope to move in the opposite direction, and then the operating component 71 can be reset, and the gear 61 also meshes with the first tooth groove 131 and the second tooth groove 221 again. Each locking mechanism is also locked again, so that the lower support component 33 will not rotate downward); finally, step on the brakes on the front wheel 101 and the rear wheel 102 so that the folded transfer vehicle cannot be moved freely in the trunk of the fire truck. In this way, the transfer vehicle can be stored in the fire truck.

[0067] Once the fire truck reaches the location requiring rescue, the foot-operated brake mechanism is deactivated to release the brakes on the front wheels 101 and rear wheels 102. With the assistance of the front and rear wheels 101 and 102, the transport vehicle is towed backward to the fire truck's trunk opening. While towing the transport vehicle backward, the operating component 71 is driven again to move relative to the base plate 1, unlocking all locking mechanisms. Under the natural force of gravity, the lower support component 33 of the front outrigger 2 will rotate downward. When the front outrigger 2 detaches from the fire truck's trunk chassis, the front outrigger 2 and the front inclined outrigger 8 will rotate back to their initial state. The transport vehicle continues to move backward until the rear outrigger 3 also detaches from the fire truck's trunk chassis. The rear outrigger 3 and the rear inclined outrigger 9 will rotate back to their initial state. At this point, the drive on the operating component 71 can be released. Under the action of the compression elasticity, all locking mechanisms are locked again, and the front outrigger 2 and rear outrigger 3 are supported on the ground. The transport vehicle continues to move backward until it is completely detached from the fire truck's trunk.

[0068] If the fire truck cannot reach the core rescue location, after the fire truck reaches the nearest accessible location, the transport vehicle loaded with firefighting equipment should be pulled off the fire truck's trunk as described above. The transport vehicle should then be pushed directly to the core rescue location using the wheels 20 under the outriggers and rear outriggers 3. If the vehicle cannot be pushed due to obstacles on the ground or other obstacles preventing movement via the wheels 20, multiple people can lift the transport vehicle using the second handle 12, moving it like a stretcher to the rescue location to begin rescue operations. This method, compared to manual transport trip after trip, not only allows for faster transport of firefighting equipment, avoiding delays in rescue time, but also avoids the physical exhaustion caused by multiple trips by hand, allowing firefighters to conserve their energy for rescue operations. Furthermore, even if firefighting equipment malfunctions, it can be directly replaced from the transport vehicle without needing to return to the fire truck twice, thus avoiding wasted time and improving rescue efficiency.

[0069] Because the fire-fighting supplies in the different storage areas on the floor of the transport vehicle are clearly visible in all directions, firefighters only need to retrieve the required supplies from the corresponding storage area. This not only eliminates the need to waste time searching for equipment, but also allows multiple people to retrieve equipment from different directions and move it away, enabling multiple people and multiple processes to be carried out simultaneously and in an orderly manner. This achieves a team-wide parallel collaborative work system, avoiding overlapping work areas that could lead to intersecting personnel movement and congestion, thereby improving team efficiency and rescue efficiency.

[0070] After the rescue is completed, the fire-fighting equipment is put back into the original storage area and sorted for storage. Then, it is folded and pushed into the trunk of the fire truck in the aforementioned manner to complete the equipment recovery.
