Figure a is a cross-sectional view of the mounting plate, figure b is a top view of the mounting plate, and figures c to e are schematic diagrams of quick-change supports of different structural specifications. In this embodiment, the mounting plate is fixedly connected to the roller mounting plate 10, and the mounting plate has multiple sets of insertion holes for installing quick-change supports. After the quick-change supports are installed through these holes, the corresponding helicopter external loadout equipment to be transported and installed is placed on the quick-change supports. It should be noted that the above-mentioned... Figures 1 to 3 The auxiliary transport and installation equipment for the helicopter external loadout shown is equipped with... Figure 6 The quick-change support shown in Figure d.

[0058] This invention provides an auxiliary transport and installation device for helicopter external equipment. Using this device, large products can be transported, lifted, moved, adjusted, and installed. Electric-assisted transport and lifting operations are convenient, replacing manual handling. It is equipped with quick-change supports with various structural designs, allowing for the installation of products with different structures, enabling diverse product applications and reducing the cost of one-to-one equipment. The lifting platform 1 can be remotely controlled, allowing the operator to observe the surrounding environment at any time. Safety edges enhance operational safety. Upon approaching the installation height, the roller mounting plate can move and rotate the product fixed on the support assembly horizontally, assisting the operator in making fine adjustments according to the actual situation, greatly improving the operability of the installation operation.

[0059] In one implementation of this invention, such as Figure 5 As shown, the lifting platform 1 is a steel welded assembly, including: a frame formed by welding square tubes, a thin steel plate wrapped around the frame, an upper flat plate on the upper end of the frame, and a circular thick steel plate welded below the frame. Specifically, mounting holes can be opened on the circular thick steel plate for fixed installation with the rising end of the electric cylinder 15 and the flange block 4.

[0060] In one implementation of an embodiment of the present invention, referring to... Figures 1 to 3 As shown, the auxiliary transportation and installation equipment provided in this embodiment of the invention may further include: mounting plate 5, washer 6, linear bearing fixing seat assembly 13, and guide shaft 14.

[0061] In this implementation, mounting plates 5 are installed on the inner sides of the support columns at the four corners of the housing 2, such as... Figure 9 As shown, Figure 1The illustrated embodiment provides a schematic diagram of the mounting plate in the auxiliary transport and installation equipment for helicopter external loads, where Figure a is a cross-sectional view and Figure b is a plan view of the mounting plate. Linear bearing mounting bracket assemblies 13 are vertically mounted via the mounting plate 5, and each linear bearing mounting bracket assembly 13 is equipped with a guide shaft 14, allowing the guide shaft 14 to move linearly in the vertical direction.

[0062] Reference Figures 1 to 3 As shown, in this implementation, based on the assembly requirements of the guide shaft 14, the housing 2 and the lifting platform 1 have through holes at the same positions at the four corners, and the upper plate of the lifting platform 1 has mounting holes at the same positions at the four corners. After the upper end face of the guide shaft 14 passes through the through holes at the corresponding positions of the housing 2 and the lifting platform 1, the washer 6 installed on the upper end face of the guide shaft 14 is fastened to the mounting hole of the upper plate with screws. That is, the upper end face of the guide shaft 14 is fixedly connected to the four corners of the lifting platform 1, which is used to maintain the stability of the movement of the lifting platform 1 during the process of the lifting platform 1 rising or falling.

[0063] In one implementation of an embodiment of the present invention, referring to... Figures 1 to 3 As shown, the auxiliary transportation and installation equipment provided in this embodiment of the invention may further include: a proximity switch mounting plate 8 and a switch rod 9. Figure 10 for Figure 1 The schematic diagram of the proximity switch mounting plate in the auxiliary transport installation equipment for helicopter external equipment provided in the embodiment shown is shown in Figure a, which is a front view, Figure b is a side view, and Figure c is a top view. Figure 11 for Figure 1 The schematic diagram shows the structure of the switch rod in the auxiliary transport and installation equipment for helicopter external equipment provided in the embodiment shown.

[0064] In this implementation, the electric cylinder 15 is electrically connected to a proximity switch mounting plate 8, which is vertically fixed inside the housing 2 and located inside the partition of the housing 2. The proximity switch mounting plate 8 is vertically equipped with a minimum proximity switch and a maximum proximity switch. In addition, a through hole is provided near the central through hole of the housing 2, and a switch rod mounting hole is provided at the corresponding position of the lifting platform 1. The switch rod 9 is fixed through the switch rod mounting hole, and the switch rod 9 passes through the through hole on the housing 2 and is located around the proximity switch mounting plate 8. During the process of the electric cylinder 15 driving the lifting platform 1 to rise or fall, the switch rod 9 triggers the minimum or maximum proximity switch on the proximity switch mounting plate 8, thereby stopping the electric cylinder 15 from lifting or lowering.

[0065] In one implementation of an embodiment of the present invention, referring to... Figures 1 to 3 As shown, the auxiliary transportation and installation equipment provided in this embodiment of the invention may further include: two limiting plates 11. For example... Figure 12 As shown, Figure 1The schematic diagram of the limiting plate in the auxiliary transport and installation equipment for helicopter external equipment provided in the embodiment shown is shown in Figure a, which is a front view, Figure b is a side view, and Figure c is a top view.

[0066] In this implementation, the limiting plate 11 is configured as a bent structure, with the straight side riveted and fixedly installed on both sides of the lifting platform 1, and the curved bent side pressing against the upper end face of the roller mounting plate 10, so that the roller mounting plate 10 can be separated from the lifting platform 1 during the omnidirectional rolling process.

[0067] Based on the installation requirements of the upper surface of the arc-shaped bent edge pressing roller mounting plate 10 of the limiting plate 11 in this embodiment of the invention, such as Figure 6 The bracket assembly 3 shown has a two-layer structure for its mounting plate. The upper mounting plate is a flat plate with the same outer contour as the lifting platform 1. The lower mounting plate is smaller around the perimeter than the upper mounting plate. Its outer contour is flush with the outer contour of the roller mounting plate 10, and it has concave arc-shaped grooves on both sides to avoid the limiting plate 11 on the roller mounting plate 10.

[0069] (1) Fixed handle 18: Two pin holes are provided on the side of the support assembly 3, roller mounting plate 10 and lifting platform 1 near the front of the electric bicycle 12. The fixed handle 18 is inserted through the pin holes to fix the support assembly 3, roller mounting plate 10 and lifting platform 1, so as to limit the omnidirectional rolling of the roller mounting plate 10.

[0070] (2) Fastener 16: Fasteners 16 are installed at the front and rear ends of the lifting platform 1 respectively, and the fasteners 16 are fixedly installed on the bracket assembly 3 from the lifting platform 1 for fixing the product during transportation.

[0071] (3) Installing the edge mat 17: After the auxiliary transport and installation equipment places the product through the quick-change support of the bracket assembly 3, the edge mat 17 is laid at the highest point of the product to ensure that the product will not continue to rise and collide with the aircraft after reaching the installation height. Figure 13 As shown, Figure 1 The illustrated embodiment provides a schematic diagram of the structure for installing the contact mat in the auxiliary transport and installation equipment for helicopter external loads, wherein figure a is a front view and figure b is a top view.

[0072] (4) A door is provided at the end of the box body 2 away from the front of the electric vehicle 12, which is used to store the auxiliary transportation and installation equipment components between the door and the partition, and to isolate the electric cylinder 15 through the partition inside the box body 2.

[0073] The following is an illustrative description of the implementation method of the auxiliary transport and installation equipment for helicopter external equipment provided in the embodiments of the present invention through a specific implementation example.

[0074] Implementation Example

[0075] Reference Figures 1 to 3 As shown, the auxiliary transport and installation equipment for helicopter external loadouts provided in this embodiment includes: a lifting platform 1, a housing 2, a bracket assembly 3, a flange block 4, a mounting plate 5, a gasket 6, a ball bearing roller 7, a proximity switch mounting plate 8, a switch lever 9, a roller mounting plate 10, a limit plate 11, a trolley 12, a linear bearing mounting bracket assembly 13, a guide shaft 14, an electric cylinder 15, a bolt fastener 16, a mounting contact mat 17, and a fixed handle 18.

[0076] like Figure 4 As shown, in this embodiment, the box 2 is made of aluminum alloy components. The interior is a frame structure formed by multiple support columns of aluminum profiles screwed together. The support plate on the outside of the aluminum profile is riveted to the outermost packaging box plate. The bottom of the box 2 is a thick aluminum plate that bears the support force of the entire equipment. Threaded holes are opened on the bottom plate to install and fix the box 2 on the electric bicycle 12. The top of the box 2 is a thin aluminum plate that is riveted to the overlap of the outer packaging box plate.

[0077] In this embodiment, an electric cylinder 15 is fixedly installed in the middle position inside the housing 2, and the electric cylinder 15 is powered by the electric scooter 12. Mounting plates 5 are respectively mounted on the inner sides of the support columns at the inner corners of the housing 2. Linear bearing mounting assemblies 13 are mounted on the mounting plates 5, and guide shafts 14 are mounted vertically through the linear bearing mounting assemblies 13. A proximity switch mounting plate 8 electrically connected to the electric cylinder 15 is also installed inside the housing 2. A switch rod 9, mounted on the lower end face of the lifting platform 1, also extends into the housing 2, close to the proximity switch mounting plate 8, so that the proximity switch mounting plate 8 can be triggered by the switch rod 9.

[0078] Based on the installation and movement requirements of the electric cylinder 15 and the four corner guide shafts 14, a central through hole is opened at the top center of the housing 2 to avoid the lifting and lowering of the electric cylinder 15. Avoidance holes are also opened at the top of the housing 2 corresponding to the positions of the guide shafts 14 and the switch rod 9. The lifting end of the electric cylinder 15 passes through the central through hole at the top of the housing 2. A flange block 4 is installed at the top and connected to the bottom center of the upper lifting platform 1 through the flange block 4, thus enabling the lifting platform 1 to rise and fall under the action of the electric cylinder 15. The guide shaft 14 passes through the corresponding avoidance holes and is fixedly connected to the four corners of the bottom of the lifting platform 1, providing guidance when the lifting platform 1 rises and preventing it from swaying. The end of the housing 2 away from the front of the electric scooter 12 is designed with a door structure for easy storage of accessories. A partition is added inside the housing to isolate the internal electrical components (i.e., the electric cylinder 15).

[0079] like Figure 5As shown, in this embodiment, the lifting platform 1 is a welded steel assembly. The overall rigidity is ensured by a frame welded from square tubes, covered with a thin steel plate. The end face of the frame is entirely covered with an upper plate. A circular thick steel plate is welded below the frame, and mounting holes are provided on the circular thick steel plate for installation with the rising end of the electric cylinder 15 and the flange block 4. Through holes are provided at the four corners of the bottom plate of the lifting platform 1 corresponding to the guide shaft 14, and the guide shaft 14 is installed. Mounting holes are provided on the upper plate of the frame of the lifting platform 1, so that washers 6 are installed on the upper end face of the guide shaft 14 and screwed into the mounting holes of the upper plate to ensure that the guide shaft 14 is fixedly connected to the lifting platform 1. Mounting holes for the switch rod are provided near the circular thick steel plate below the lifting platform 1, and the switch rod 9 is installed below the lifting platform 1. The position of the switch rod 9 is matched with the proximity switch mounting plate 8. When the lifting platform 1 rises or falls, the switch rod 9 moves accordingly. When it reaches the highest or lowest limit height of the electric cylinder 15, the switch rod 9 triggers the proximity switch on the proximity switch mounting plate 8, stopping the lifting action and protecting the motor. In addition, two pin holes are provided on the upper plate of the lifting platform 1 to accommodate the installation of the fixed handle 18.

[0080] In this implementation example, a roller mounting plate 10 is placed on the upper end face of the lifting platform 1. The bottom end face of the roller mounting plate 10 is connected to and mounted with a steel ball roller 7 by screws, so that the roller mounting plate 10 can roll in all directions on the lifting platform 1. The roller mounting plate 10 has two pin holes for mounting and fixing handles 18.

[0081] In this implementation example, limiting plates 11 are riveted and installed on both sides of the lifting platform 1. The limiting plates 11 are bent plates, and the bent edges press on the roller mounting plate 10 to prevent the roller mounting plate 10 from detaching from the lifting platform 1.

[0082] like Figure 6 As shown, in this embodiment, the upper end face of the roller mounting plate 10 is equipped with a bracket assembly 3. The bracket assembly 3 consists of a mounting plate and multiple quick-change supports. The mounting plate has a two-layer structure. The outer contour of the upper mounting plate is the same as that of the lifting platform 1, and the upper mounting plate is rectangular. The upper mounting plate of the bracket assembly 3 has holes for the matching quick-change supports. The lower mounting plate is machined with a groove to avoid the bending plate of the limiting plate 11, and its thickness is greater than that of the limiting plate 11, so as to realize the omnidirectional movement of the bracket assembly 3. The lower mounting plate has holes to avoid the steel ball roller 7. Countersunk holes are opened at the four corners of the mounting plate, which are matched with the corresponding threaded holes at the four corners of the roller mounting plate 10 and fixed with screws. The mounting plate of the bracket assembly 3 also has two pin holes for installing and fixing the handle 18.

[0083] like Figure 7As shown, in this embodiment, the roller mounting plate 10 is a rectangular steel plate with the same outer contour as the lower mounting plate of the bracket assembly 3. The roller mounting plate 10 is installed below the bracket assembly 3, and the four corners are threaded holes and connected and fixed to the mounting plate of the bracket assembly 3 with screws. The roller mounting plate 10 has holes, and the bottom is connected and installed with screws to install steel ball rollers 7, so that the roller mounting plate 10 can roll in all directions on the lifting platform 1.

[0084] It should be noted that the two pin holes on the mounting plate of the bracket assembly 3, the two pin holes on the roller mounting plate 10, and the two pin holes on the upper plate of the lifting platform 1 are positioned in a corresponding manner, so that after the fixed handle 18 is installed, it can be inserted into the lifting platform 1 through the roller mounting plate 10 and the bracket assembly 3 to fix the bracket assembly 3 and prevent it from sliding in all directions.

[0085] like Figure 8 As shown, in this embodiment, flange block 4 is a square steel plate with a threaded hole in the center to mate with the end of electric cylinder 15. Flange block 4 has through holes at its four corners to mate with the base plate of lifting platform 1 and is connected by screws to achieve the connection between the rising end of electric cylinder 15 and lifting platform 1.

[0086] like Figure 9 As shown, the mounting plate 5 in this embodiment can be a thick aluminum plate with four countersunk holes symmetrically arranged on the axis for mounting the linear bearing mounting bracket 13, and four through holes for connecting to the inner frame of the housing 2; after installation, the linear bearing mounting bracket 13 and the guide shaft 14 are engaged.

[0087] like Figure 10 As shown, in this embodiment, the proximity switch mounting plate 8 is installed on the inner frame of the housing 2, and its position is matched with the switch rod 9. The proximity switch mounting plate 8 is an aluminum plate bracket structure, on which two proximity switches are installed to limit the highest and lowest positions of the lifting mechanism, respectively.

[0088] like Figure 11 As shown, in this embodiment, the switch rod 9 is installed on the lower end face of the lifting platform 1. It is a cylindrical stepped rod with the top cylinder engaging with the hole below the lifting platform 1. The rod body can contact the proximity switch mounting plate 8 through the housing 2, so as to trigger the proximity switch mounting plate 8 at the highest and lowest positions to shut off the movement of the electric cylinder 15.

[0089] like Figure 12 As shown, the limiting plate 11 in this embodiment is a bent steel plate with a straight edge on one side and rivet holes for riveting and mounting on both sides of the lifting platform 1. The other side has an arc-shaped groove, with the bent edge pressing on the roller mounting plate 10 to prevent the roller mounting plate 10 from detaching from the lifting platform 1. It can be seen that the arc-shaped groove on the side of the limiting plate 11 pressing on the roller mounting plate 10 is similar in shape to the lower mounting plate in the bracket assembly 3.

[0090] like Figure 13 As shown, in this implementation example, the installation contact mat 17 is a rubber plate with evenly distributed and bonded safety contact edges, which is laid out as a whole at the highest point of the product during use.

[0091] The following describes the operation of the auxiliary transport and installation equipment for helicopter external equipment provided in the embodiments of the present invention.

[0092] In a practical application scenario, it is necessary to transport and install helicopter external equipment to the installation location. In this example, the support assembly 3 of the auxiliary transport and installation equipment for the helicopter external equipment cooperates with the product support and is secured with a bolt fastener 16. A fixing handle 18 is inserted into the lifting platform 1 after passing through the mounting plate and roller mounting plate 10 of the support assembly 3, ensuring the support assembly 3 is fixed during transport. After the product is moved to the installation location, the installation contact mat 17 is placed at the highest point. The electric cylinder 15 is operated to raise the lifting platform 1, the upper roller mounting plate 10, the support assembly 3, and the product. Once close to the installation location, the fixing handle 18 is removed, and the roller mounting plate 10, the support assembly 3, and the product are horizontally adjusted to ensure alignment between the installation point and the product. The operator then performs the work. After completion, the bolt fastener 16 is released, and the electric cylinder 15 lowers the lifting platform 1, the upper roller mounting plate 10, and the support assembly 3 back to their initial positions. The fixing handle 18 is then installed, completing all operations.

[0093] The auxiliary transportation and installation equipment for helicopter external equipment provided in this embodiment of the invention effectively replaces the work of multiple people in handling and lifting when transporting and loading products, ensuring a safe and reliable docking and installation position for the products, and fully meeting the on-site assembly requirements.

[0094] Helicopter external loadouts are mostly large and heavy products, and their installation has traditionally relied on multiple operators working together to lift them to the installation position and then lift them for installation. The auxiliary transport and installation equipment for helicopter external loadouts provided in this invention allows a single operator to handle the product. The equipment can be raised and lowered to meet the installation height requirements. At the installation position, the lifting platform can move horizontally and rotate to facilitate on-site installation and adjustments. Furthermore, the overall structure of the auxiliary transport and installation equipment allows for quick-change of product brackets, meeting the requirements for auxiliary installation of external loadouts on armed helicopters such as the SAW type, and has wide applicability.
