Description

Technical Field

[0001] This application relates to the technical field of helicopter take-off and landing, and more particularly to a vehicle-mounted folding deck system. Background Technology

[0002] When natural disasters and engineering accidents occur, helicopter airlift has significant advantages in emergency rescue and material transfer. However, disaster sites or areas with complex terrain such as mountainous regions often fail to meet the site requirements for helicopter take-off and landing. Therefore, there is an urgent need for a mobile temporary take-off and landing platform. Vehicle-mounted mobile decks can provide safe and reliable take-off and landing sites for helicopters in complex and harsh environments.

[0003] Existing related technologies disclose a vehicle-mounted foldable helicopter pad, including a truck, hydraulic rods, a deck, a chute, steel wheels, and marking paint. The hydraulic rods are fixedly connected to the truck, the chute is fixedly embedded in the deck, the steel wheels are fixedly connected under the deck, the chute and the steel wheel are nested together, and the size of the steel wheel corresponds to the chute. Marking paint is painted on the deck, and the deck is neatly stacked on the truck.

[0004] Regarding the aforementioned technologies, when using a foldable helicopter pad, operators need to manually unfold each deck before hydraulic rods can be used to hydraulically lift it, providing a stable take-off and landing surface for the helicopter. However, manually unfolding each deck requires a significant amount of manpower. Summary of the Invention

[0005] This application addresses the shortcomings of existing technologies by providing a vehicle-mounted folding deck system that reduces the manpower required for deck deployment and further improves deck deployment efficiency.

[0006] The technical solution to the above-mentioned technical problems in this application is as follows:

[0007] A vehicle-mounted folding deck system includes a support deck, an extension deck movably connected to the support deck, and hoisting mechanisms for moving the extension deck at both ends of the support deck; slide rail assemblies are provided at both ends of the support deck, and the hoisting mechanisms are placed on the slide rail assemblies and slidably connected to the slide rail assemblies.

[0008] By adopting the above technical solution, when a landing surface is needed for a helicopter, the hoisting mechanism lifts the extension deck located above the support deck. Then, the hoisting mechanism slides along the length of the slide rail assembly and connects with the slide rail assembly. During this process, the hoisting mechanism drives the extension deck to gradually move to both sides of the support deck, thereby realizing the automatic deployment process of the extension deck, reducing the manpower required for the deployment of the extension deck, and further improving the deployment efficiency of the extension deck.

[0009] Furthermore, the hoisting mechanism includes a sliding trolley, a pile, a crossbeam, and a hoisting pulley. The sliding trolley is slidably placed on the slide rail assembly. The bottom end of the pile is connected to the upper end face of the sliding trolley, and the top end of the pile is connected to the crossbeam. The hoisting pulley is disposed on the crossbeam, and the lower end of the hoisting pulley is provided with a hoisting hook for hoisting the extended deck.

[0010] Furthermore, the sliding trolley is equipped with a self-locking component, which is used to lock the relative position of the sliding trolley and the slide rail assembly.

[0011] Furthermore, the upright pile is rotatably connected to the sliding trolley via a folding hinge, and the rotation axis of the upright pile is parallel to the length direction of the support deck.

[0012] Furthermore, both ends of the extended deck are provided with supporting beams and lifting components mounted on the supporting beams. The lifting components are used to cooperate with the lifting mechanism. The lifting components include deck lifting points and slings fixedly connected to the deck lifting points. The slings are used to connect with the lifting hook.

[0013] Furthermore, each of the supporting beams has a folding support hinged to its lower end face. When the extension deck is unfolded, the folding support is used to support the supporting beams and the extension deck.

[0014] Furthermore, the slide rail assembly includes a fixed slide rail and a folding slide rail. The fixed slide rail is fixedly connected to the support deck, and the folding slide rail is rotatably connected to both ends of the fixed slide rail. The rotation axis of the folding slide rail is set in the vertical direction.

[0015] Furthermore, each of the lower end faces of the folding slide rail is hinged with a folding support leg, which is used to support the folding slide rail when it is unfolded.

[0016] Furthermore, both sides of the support deck are rotatably connected to lateral columns, and the rotation axis of the lateral columns is set in the horizontal direction.

[0017] Furthermore, both sides of the support deck are provided with tenon-type connectors, and one side of the extension deck is provided with a mortise-type connector that mates with the tenon-type connectors.

[0018] In summary, compared with the prior art, the beneficial effects of the above technical solution are:

[0019] When a landing surface is needed for a helicopter, the hoisting mechanism lifts the extension deck located above the support deck. Then, the hoisting mechanism slides along the length of the slide rail assembly and connects with the slide rail assembly. During this process, the hoisting mechanism drives the extension deck to gradually move to both sides of the support deck, thereby realizing the automatic deployment of the extension deck, reducing the manpower required for the deployment of the extension deck, and further improving the deployment efficiency of the extension deck.

[0025] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0026] This application discloses a vehicle-mounted folding deck system.

[0027] Reference Figures 1-4 A vehicle-mounted folding deck system includes a transport vehicle 1 and a support deck 2.

[0028] The support deck 2 is arranged horizontally and fixedly connected to the transport vehicle 1. Five extension decks 3 are movably connected to the support deck 2. The number of extension decks 3 can be set according to specific usage requirements. In this embodiment, the number of extension decks 3 is two.

[0029] When the transport vehicle 1 transports the support deck 2 and the extension deck 3, both extension decks 3 are located directly above the support deck 2. Compared to transporting the extension decks 3 by directly unfolding them or by placing them vertically on both sides of the support deck 2, this effectively reduces the vehicle's volume and lateral windward area during transport, thus improving transport efficiency, especially in adverse conditions such as strong winds.

[0030] Reduce transportation safety hazards under natural conditions.

[0031] When a landing surface is needed for helicopters, the extension deck 3 moves to both sides of the supporting deck 2, assembling into a stable plane to facilitate helicopter takeoff and landing.

[0032] The number of decks 3 can meet the helicopter's take-off and landing needs in different situations, thereby improving the flexibility of the vehicle-mounted deck.

[0033] Both ends of the support deck 2 are provided with hoisting mechanisms 4 for moving the extension deck 3. Both ends of the support deck 2 are provided with slide rail assemblies 5. The hoisting mechanism 4 is placed on the slide rail assembly 5 and is slidably connected to the slide rail assembly 5. When the hoisting mechanism 4 drives the extension deck 3 to move, the hoisting mechanism 4 moves along the width direction of the support deck 2.

[0034] When a landing surface is needed for a helicopter, the hoisting mechanism 4 lifts the extension deck 3 located above the support deck 2. Then, the hoisting mechanism 4 slides along the length of the slide rail assembly 5 and connects with the slide rail assembly 5. During this process, the hoisting mechanism 4 drives the extension deck 3 to gradually move to both sides of the support deck 2, thereby realizing the automatic deployment process of the extension deck 3 and reducing the manpower required for the deployment of the extension deck 3.

[0035] 5. In this embodiment, the hoisting mechanism 4 is provided in two sets, and the height of the two sets of hoisting mechanisms 4 corresponds to the height of the two extension decks 3 respectively. When it is necessary to provide a take-off and landing plane for the helicopter, the two sets of hoisting mechanisms 4 respectively lift the two extension decks 3 and deploy the two extension decks 3 at the same time, which can further improve the deployment efficiency of the extension decks 3.

[0036] The hoisting mechanism 4 includes a sliding trolley 41, a pile 42, a crossbeam 43, and a hoisting pulley 44. The sliding trolley 41 is slidably placed on the slide rail assembly 5. The bottom end of the pile 42 is connected to the upper end face of the sliding trolley 41, and the top end of the pile 42 is connected to the crossbeam 43. The hoisting pulley 44 is set on the crossbeam 43, and the lower end of the hoisting pulley 44 is provided with a hoisting hook 45 for hoisting the extension deck 3.

[0037] When the lifting mechanism 4 needs to lift the extension deck 3 located above the support deck 2, the lifting hook 45 lifts the extension deck 3, realizing the connection between the extension deck 3 and the lifting mechanism 4. Then the sliding trolley 41 slides on the slide rail assembly 5. During this process, the pile 42, the crossbeam 43 and the lifting pulley 44 all move synchronously with the sliding trolley 41, thereby driving the extension deck 3 to move and realizing the automatic movement process of the extension deck 3.

[0038] The lifting pulley 44 is equipped with a lifting mechanism (not shown in the figure) for raising and lowering the lifting hook 45. In this embodiment, the lifting mechanism is specifically a chain hoist structure. After the lifting hook 45 is connected to the extension deck 3, the operator raises the lifting hook 45 through the lifting mechanism, and the lifting hook 45 then lifts the extension deck 3, making it easier for the extension deck 3 to be moved down from above the support deck 2. The lifting mechanism makes the process of raising and lowering the extension deck 3 by the lifting hook 45 much less strenuous, greatly saving manpower.

[0039] The sliding trolley 41 is equipped with a self-locking component, which is used to lock the relative position of the sliding trolley 41 and the slide rail assembly 5. When the sliding trolley 41 moves to the desired position, the self-locking component locks the sliding trolley 41, making the relative positional relationship between the sliding trolley 41 and the slide rail assembly 5 more stable, so that the lifting mechanism 4 can stably place the extension deck 3 in the desired position, thereby making the conveying process of the extension deck 3 by the sliding trolley 41 more stable.

[0040] In this embodiment, the self-locking component includes four self-locking nuts arranged vertically. The self-locking nuts penetrate the upper end face of the sliding trolley 41, and the bottom of the slide rail assembly 5 has multiple screw holes. The self-locking nuts are all threadedly connected to the screw holes. When the trolley reaches the position that needs to be fixed, the operator rotates the self-locking nuts to tighten them into the screw holes, thereby achieving a fixed connection between the sliding trolley 41 and the slide rail assembly 5.

[0041] The upright pile 42 is rotatably connected to the sliding trolley 41 via a folding hinge 46, and the rotation axis of the upright pile 42 is parallel to the length direction of the support deck 2. The folding hinge 46 is installed on the upper end face of the sliding trolley 41 via a mechanical hinge, and the upright pile 42 is fixedly connected to the folding hinge 46. As the mechanical hinge is extended or retracted, the rotation locking function of the folding hinge 46 can be realized.

[0042] After the extension deck 3 is moved and placed on both sides of the support deck 2, the lifting device is in an idle state. At this time, the operator can rotate the upright pile 42 to realize the relative rotation process between the upright pile 42 and the sliding trolley 41, and then lower the upright pile 42 so that the upright pile 42, the crossbeam 43 and the lifting pulley 44 are all placed on the horizontal surface, so that the upright pile 42 will not interfere with the helicopter's take-off and landing process.

[0043] Both ends of the extended deck 3 are provided with supporting beams 6 and lifting components 7 set on the supporting beams 6. The lifting components 7 are used to connect with the lifting mechanism 4. The lifting components 7 include deck lifting points 71 and slings 72. Each end of the extended deck 3 is fixed with two deck lifting points 71. The slings 72 are located between the two deck lifting points 71. The two ends of the slings 72 are fixedly connected to the two deck lifting points 71 respectively. A lifting ring 73 is fixed in the middle of the slings 72. The lifting ring 73 is used to connect with the lifting hook 45.

[0044] When the lifting mechanism 4 needs to lift the extension deck 3 located above the support deck 2, the lifting hook 45 passes through the lifting ring 73 to achieve the connection between the lifting hook 45 and the sling 72. At this time, the lifting mechanism 4 lifts, so that the lifting hook 45 lifts the lifting ring 73, the sling 72 and the deck lifting point 71 in sequence, thereby lifting the extension deck 3. The cooperative connection between the lifting hook 45 and the lifting ring 73 can achieve a stable connection between the extension deck 3 and the lifting mechanism 4.

[0045] The lower end face of the support beam 6 is hinged with a folding column 8. When the extension deck 3 is retracted, the folding column 8 is in the horizontal direction, saving transport space; when the extension deck 3 is unfolded, the folding column 8 is in the vertical direction. At this time, the folding column 8 is used to support the support beam 6 and the extension deck 3.

[0046] When the transport vehicle 1 transports the support deck 2 and the extension deck 3, the operator rotates the folding support column 8 to a horizontal position, so that the folding support column 8 is placed at the lower end of the support beam 6, which saves transport space. When the extension deck 3 is unfolded, the operator rotates the folding support column 8 to a vertical position. At this time, the upper end of the folding support column 8 abuts against the support beam 6, and the lower end of the folding support column 8 abuts against the ground, so that the extension deck 3 can be stably placed in a horizontal position, making the planar structure assembled by the extension deck 3 and the support deck 2 more stable.

[0047] The slide rail assembly 5 includes a fixed slide rail 51 and a folding slide rail 52. The fixed slide rail 51 is fixedly connected to the support deck 2, and the folding slide rails 52 are rotatably connected to both ends of the fixed slide rail 51. The rotation axis of the folding slide rails 52 is arranged in the vertical direction. The fixed slide rail 51 includes an inner slide rail 511 and an outer slide rail 512. The lower lifting mechanism 4 is movably connected to the inner slide rail 511, and the higher lifting mechanism 4 is movably connected to the outer slide rail 512. One folding slide rail 52 is rotatably connected to the inner slide rail 511, and the other folding slide rail 52 is rotatably connected to the outer slide rail 512.

[0048] When the transport vehicle 1 transports the support deck 2 and the extension deck 3, the operator rotates the folding slide rail 52 to both sides of the support deck 2 to save transport space; when the extension deck 3 needs to be unfolded, the operator rotates the folding slide rail 52 to the width direction of the support deck 2. At this time, the folding slide rail 52 and the fixed slide rail 51 are on the same straight line, which facilitates the horizontal movement of the hoisting mechanism 4.

[0049] Each folding slide rail 52 has a folding support leg 53 hinged to its lower end. When the folding slide rail 52 is unfolded, the folding support leg 53 supports the folding slide rail 52. When the folding slide rail 52 and the fixed slide rail 51 are on the same straight line, the operator rotates and unfolds the folding support leg 53, so that the folding support leg 53 is in the vertical direction. At this time, the lower end of the folding support leg 53 abuts against the ground, so that the folding slide rail 52 can be stably placed in a horizontal position, thereby making the horizontal track structure formed by the folding slide rail 52 and the fixed slide rail 51 more stable.

[0050] Both sides of the support deck 2 are rotatably connected to lateral columns 9, and the rotation axis of the lateral columns 9 is set in the horizontal direction. When the transport vehicle 1 transports the support deck 2 and the extension deck 3, the operator rotates the lateral columns 9 to the vertical direction, so that the lateral columns 9 are located on both sides of the support deck 2, in order to save transport space, and at the same time limit the support deck 2 and the extension deck 3, so that the support deck 2 and the extension deck 3 are not easy to fall off.

[0051] When the extension deck 3 needs to be deployed, the operator rotates the lateral column 9 to the horizontal direction. At this time, the lateral column 9 is set along the width direction of the support deck 2. The lateral column 9 can support the extension deck 3, so that the extension deck 3 can be placed more stably in the horizontal direction for use.

[0052] In this embodiment, the support deck 2 has tenon-type connectors 10 on both sides, and the extension deck 3 has a mortise-type connector 11 on one side that engages with the tenon-type connectors 10. When multiple sets of extension decks 3 are provided on both sides of the support deck 2, one side of the extension deck 3 has a mortise-type connector 11, and the other side of the extension deck 3 has a tenon-type connector 10. When the extension deck 3 moves to one side of the support deck 2, the mortise-type connector 11 engages with the tenon-type connector 10, making the relative positional relationship between the support deck 2 and the extension deck 3 more stable.

[0053] Both ends of the support deck 2 and the extension deck 3 are provided with pin holes 12 and fixed pins that cooperate with the pin holes 12. When the extension deck 3 moves to one side of the support deck 2, the operator inserts the fixed pins into the two adjacent pin holes 12 to position and splice the decks and ensure the integrity of the decks, thereby improving the stability of the relative positional relationship between the support deck 2 and the extension deck 3.

[0054] The implementation principle of a vehicle-mounted folding deck system according to an embodiment of this application is as follows: When a landing plane is required for a helicopter, the operator rotates the lateral column 9, the folding slide rail 52, and the folding support leg 53 respectively, so that the lateral column 9 and the folding slide rail 52 are both set along the width direction of the support deck 2. The hoisting mechanism 4 lifts the extension deck 3 located above the support deck 2, and then the hoisting mechanism 4 moves along the length direction of the slide rail assembly 5. During this process, the hoisting mechanism 4 drives the extension deck 3 to gradually move to both sides of the support deck 2, thereby realizing the automatic unfolding process of the extension deck 3, reducing the human resources required for the unfolding action of the extension deck 3, and further improving the unfolding efficiency of the extension deck 3.

[0055] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
