[0027] The beneficial effects of this utility model are as follows: This utility model embodiment provides an intelligent pressure sealing machine for headrest-type life-saving parachutes. Designed with the concepts of "intelligentization, automation, and universality," the power source can provide pressure covering the pressurization range of existing headrest-type life-saving parachute boxes. It is equipped with a headrest-type parachute box protective plate and pressure plate assembly compatible with existing ones, achieving automatic pressurization of headrest-type life-saving parachutes in all states. Using power system 2 as the power source, a pulse-plus-direction control method can provide stable, precise, and controllable pressure to the packaging machine. Furthermore, by analyzing the technical parameters affecting the pressurization effect of the parachute, the control system collects and records pressure and displacement parameter signals. Human-machine interaction is achieved using control panel 3-2 and PLC controller 3-1-1. The operator inputs parameters and maintenance information through control panel 3-2, and control system 3 drives power system 2 to complete automatic operation. Simultaneously, a manual operation control mode is retained to allow for feedback correction of control parameters based on packaging effect. The intelligent pressure sealing machine provided by this utility model embodiment has the following beneficial effects:

[0028] First, through the cooperative structure of the crossbeam 1-4, pressure plate assembly 1-6, and operating handle 1-5 in the main mechanical structure 1, the relative position of the pressure plate assembly 1-6 and the crossbeam 1-4 can be adjusted by the operating handle 1-5. This allows for the placement of the parachute box and canopy of the headrest-type life-saving parachute by changing the relative position of the pressure plate assembly 1-6 and the crossbeam 1-4, or the initial pressing of the canopy by the pressure plate assembly 1-6. Furthermore, the packaging protective plate and pressure plate assembly can be replaced according to different models of headrest parachute boxes, realizing an intelligent pressure sealing machine that integrates universality, automation, and digital intelligence.

[0029] Secondly, the servo-driven electric cylinders 2-2, symmetrically arranged on both sides of the power system, drive the crossbeam 1-4 and the pressure plate assembly 1-6 to synchronously perform up-and-down reciprocating motion, so that the pressure plate assembly 1-6 can pressurize and seal the headrest-type life-saving parachute placed in the parachute box 1-7. In addition, the servo motor 2-1 in the power system can provide a wider pressure range and facilitate the association with the control system. Furthermore, by adopting a pulse transmission frequency determined by the set upward and downward pressure speed, the entire control pulse speed is output according to a trapezoidal structure model, making the control process smooth, reliable, and accurate.

[0030] Third, through the configuration of the control system, on the one hand, technical parameters and maintenance information during the pressurization process can be set and recorded, and displayed on the screen or exported through the output interface, providing data support for the optimal pressurization scheme of various types of umbrellas; on the other hand, the current sealing pressure, screw displacement, and pressure holding time can be monitored in real time. When the system malfunctions, or the pressure or displacement exceeds the set standard value, the system alarm function will be triggered to ensure safety and reliability during use; furthermore, human-machine interaction can be achieved through the PLC controller and control panel to realize the standardization and automation control of the pressurization process; in addition, a dual mode of automatic operation and manual operation can be adopted. The parameter settings of automatic operation can be adjusted by judging the pressurization effect through manual operation, and the two-way feedback correction can obtain the optimal pressurization scheme for various types of umbrellas.

It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0048] As explained in the background section, the current headrest-type life-saving parachute sealing method suffers from inconsistent quality standards due to the reliance on manual visual inspection during pressurization, resulting in inconsistent sealing states.

[0049] In addition, for headrest-type life-saving parachutes that require secondary pressurization, the pressure must be released to complete the parachute line threading before secondary pressurization can be performed to complete the sealing work. There are no reference objects or relevant indicator requirements for the two pressurization processes, and the operation is completed entirely by experience and manual visual inspection, resulting in inconsistent quality standards.

[0053] like Figure 1 As shown, this utility model embodiment provides an intelligent pressure sealing machine for headrest-type life-saving parachutes. The intelligent pressure sealing machine includes: a main mechanical structure 1, a power system 2, and a control system 3. This utility model embodiment achieves intelligent pressure sealing of the headrest-type life-saving parachute through the coordinated operation of the main mechanical structure 1 and the power system 2, and the working control mode of the control system 3.

The top of the pressure plate assembly 1-6 passes through the assembly hole opened in the middle of the crossbeam 1-4 from the bottom of the crossbeam 1-4, and the operating handle 1-5 is installed through the top of the crossbeam 1-4. The operating handle 1-5 is used to adjust the relative position of the pressure plate assembly 1-6 and the crossbeam 1-4.

[0057] In this embodiment of the present invention, the drive component in the control system 3 is electrically connected to the servo driver 2-3 of the power system 2, and is used to control the servo driver 2-3 of the power system 2 through the control system 3, so as to control the servo electric cylinders 2-2 on both sides to perform up-and-down reciprocating motion synchronously, and drive the crossbeam 1-4 and the pressure plate assembly 1-6 to perform up-and-down reciprocating motion synchronously, thereby using the pressure plate assembly 1-6 to perform pressure sealing on the headrest-type life-saving parachute placed in the parachute box in the protective box 1-7.

[0058] In one implementation of this utility model embodiment, such as Figures 2 to 9 As shown, the specific structural forms of each component in the main mechanical structure 1 are provided.

[0059] In this implementation, the chassis 1-1 is a box structure with an open top. Caster seats are symmetrically arranged on both sides of the box structure, and casters are installed at the bottom of the caster seats. The chassis 1-1 as a whole forms an I-beam structure. In one specific implementation, the chassis dimensions are: 986mm (length) × 788mm (width) × 190mm (height) (without casters). The chassis 1-1 can be composed of front and rear support plates, a base plate, casters, and left and right covers. The box structure of the chassis 1-1 is machined and welded from hot-rolled channel steel, and the base plate is made of 20mm thick 20# steel plate. Four 40mm diameter casters are installed at the bottom for easy movement.

[0060] The column platform 1-2 in this implementation includes: an installation platform and four columns fixedly connected to the bottom of the installation platform; the four columns are screwed to the bottom plate of the chassis 1-1 by their bottom screw sections, and the four columns are screwed to the installation platform by their top screw sections; a protective box 1-7 is installed on the top of the installation platform for placing and fixing the umbrella box of the headrest-type life-saving parachute through the protective box 1-7; four pressure sensors 3-1-3 are respectively installed on the top of the four columns for collecting the sealing pressure.

[0061] In one specific implementation, the installation platform is, for example, machined from Q235 carbon structural steel with a thickness of 20mm; the four columns are made of high-quality seamless carbon steel pipes, with a specification of φ40×690mm, and are fixed to the bottom plate of the chassis 1-1 by screws at their bottom; the bottom of the installation platform is screwed to the top plate of each pressure sensor 3-1-3 and the control cabinet 3-1 respectively, and the top of the installation platform is screwed to the protective bucket box 1-7 to support the protective bucket box 1-7.

[0062] In this implementation, there are two crossbeam seats 1-3: a first crossbeam seat and a second crossbeam seat. The two crossbeam seats are installed on the piston tops of the two servo electric cylinders 2-2 respectively. The two ends of the crossbeam 1-4 are respectively provided with mounting ends for connecting with the first crossbeam seat and the second crossbeam seat. A screw assembly hole is opened in the middle of the crossbeam 1-4.

[0063] In one specific implementation, the crossbeams 1-4 are integrally CNC machined from 30CrMnSiA steel and subjected to quenching and tempering heat treatment to further improve their tensile strength and fatigue strength.

[0064] The pressure plate assembly 1-6 in this implementation includes: a screw, a screw connector, and a pressure plate; the bottom end of the screw is screwed and fixed to the pressure plate through the screw connector; the screw of the pressure plate assembly 1-6 passes through the screw mounting hole in the middle of the crossbeam 1-4 from the bottom, and the screw is fitted with an operating handle 1-5 through the through hole at its top end, which is used to rotate the screw to move the pressure plate assembly 1-6 up and down relative to the crossbeam 1-4, so as to cooperate in placing the parachute box and canopy of the headrest-type life-saving parachute by changing the relative position of the pressure plate assembly 1-6 and the crossbeam 1-4, or to press the parachute canopy into place by the pressure plate assembly 1-6. In a specific implementation, the pressure plate assembly 1-6 is controlled as a whole by turning the operating handle 1-5, that is, the length of the pressure plate assembly 1-6 below the crossbeam 1-4 is adjusted by rotating the operating handle 1-5.

[0065] Furthermore, in a preferred embodiment of this utility model, such as Figure 5 As shown, in the above implementation, the first crossbeam seat is configured as a detachable structure, with an inner slip ring of sleeve structure, an upper slip ring and a lower slip ring of annular structure, and a fastener located at the top of the upper slip ring; in addition, the second crossbeam seat includes a central column forming an integral structure, and an upper plate and a lower plate located at the upper and lower ends of the central column, with a threaded hole opened on the outer periphery of the upper plate.

[0066] The crossbeam 1-4, which mates with the two crossbeam seats mentioned above, has a mounting through hole at one end and a semi-circular hook-shaped structure at the other end. This structure is fitted onto the outside of the inner sliding ring of the first crossbeam seat through the mounting through hole, located above the upper sliding ring, and secured by the upper sliding ring and fasteners. This allows the crossbeam 1-4 to rotate around the inner sliding ring, ensuring smooth rotation. The semi-circular hook-shaped structure at the other end engages with and fits onto the second crossbeam seat. The semi-circular hook-shaped structure of the crossbeam 1-4 has a threaded hole for engaging with a threaded hole on the second crossbeam seat to install a locking pin to prevent rotation of the crossbeam 1-4. In a specific implementation, the threaded hole on the outer periphery of the upper plate of the second crossbeam seat is located directly above the threaded hole on the semi-circular hook-shaped structure of the crossbeam 1-4, with the two threaded holes overlapping. A locking pin passes through the threaded hole in the upper plate of the second crossbeam seat and connects to the threaded hole in the crossbeam 1-4. Preferably, the locking pin has knurled tips for easy hand-tightening installation.

[0067] In one implementation of this utility model embodiment, such as Figure 9As shown, the protective box 1-7 is a box structure with an open top, containing three movable protective panels and a wooden base. The bottom of the protective box 1-7 is fitted with a wooden base, and the side panel of the wooden base fits against one side of the box. The other three sides of the box are respectively opened and connected to the movable protective panels inside the protective box 1-7 by locking screws, so that the protective panels can be firmly fixed to the umbrella box by rotating the locking screws. In addition, iron handles are installed on both sides of the protective box 1-7 to facilitate the overall movement of the sealing machine.

[0068] In one implementation of this utility model embodiment, such as Figure 9 As shown, the main mechanical structure 1 may also include: guide cylinders 1-8.

[0069] In this implementation, the guide tube 1-8 is placed inside the protective box 1-7 and located in the umbrella box. The excess parachute canopy of the life-saving parachute in the umbrella box passes through the bottom of the guide tube 1-8 through the guide tube 1-8, and is then pressed onto the parachute canopy inside the guide tube 1-8 by the pressure plate of the pressure plate assembly 1-6.

[0070] In one implementation of this utility model embodiment, such as Figure 10 As shown, one structural form of the power system 2 is provided. The power system 2 in this implementation includes: servo motor 2-1, servo electric cylinder 2-2, and servo driver 2-3.

[0071] In this implementation, the power system 2 is electrically driven. The servo driver 2-3 is electrically connected to the servo motor 2-1 and the control system 3 respectively. The servo motor 2-1 is equipped with two symmetrically arranged output shafts, which are connected to the servo electric cylinders 2-2 on both sides. The servo driver 2-3 converts the electrical signal of the control system 3 into the working signal of the servo motor 2-1. The servo motor 2-1 mechanically drives the servo electric cylinders 2-2 on both sides to perform up-and-down reciprocating motion synchronously. This drives the crossbeam 1-4 and the pressure plate assembly 1-6 to perform up-and-down reciprocating motion synchronously, so as to perform pressure sealing on the headrest-type life-saving parachute placed in the parachute box in the protective box 1-7 through the pressure plate assembly 1-6.

[0072] In one specific embodiment, the pressure sealing machine is externally powered by AC380V / 50Hz, with a power not exceeding 8kW. The two servo electric cylinders 2-2 are non-standard custom parts, with a total rated thrust of 5.8t (58KN), meeting the pressure range requirement of 0~50000N. Their stroke is greater than 600mm, meeting the technical requirement of a pressurization stroke of 0~500mm. The servo electric cylinder 2-2 has a rated speed of 40mm / s and moves very smoothly.

[0073] In one implementation of this utility model embodiment, reference is made to... Figures 11 to 13As shown, a structural form and control form of the control system are provided. The control system 3 in this implementation includes: a control cabinet 3-1, a PLC controller 3-1-1, an embedded driver 3-1-2, a pressure sensor 3-1-3 built into the control cabinet 3-1, and a control panel 3-2 set outside the control cabinet 3-1.

[0074] In this implementation, the control panel 3-2 is electrically connected to the PLC controller 3-1-1 in the control cabinet 3-1 via a cable. The PLC controller 3-1-1 in the control cabinet 3-1 is electrically connected to the embedded driver 3-1-2 via solder. Each pressure sensor 3-1-3 is connected to the embedded driver 3-1-2 via a terminal block. The embedded driver 3-1-2 is connected to the servo driver 2-3 in the power system 2 via a terminal block.

[0075] In one specific embodiment, the control panel 3-2 is equipped with a touch screen and operation buttons. The control panel 3-2 can control the power supply to or from the operating power source of the system; the operation buttons control the raising and lowering of the lifting mechanism screw; the touch screen displays the system's operating status and allows for touch screen operation to control the raising and lowering of the lifting mechanism screw. When a system malfunctions, pressing an operation button will cut off the power to the system and stop its operation. Furthermore, the dimensions of the control panel 3-2 are: length 380mm, width 350mm, and height 860mm; the bottom of the control panel 3-2 is equipped with a detachable fixing base, which can be screwed onto the side wall of the control cabinet 3-1, with its center approximately 1300mm above the ground (including the base height).

[0076] In this implementation method, the control operation of control system 3 is as follows:

[0077] The PLC controller 3-1-1 receives the working instructions from the control panel 3-2. According to the preset program logic, it transmits the working instructions to the embedded driver 3-1-2. The embedded driver 3-1-2 sends electrical signals to the servo driver 2-3. The servo driver 2-3 controls the servo motor 2-1 to execute the working instructions. The servo motor 2-1 mechanically drives the servo electric cylinders 2-2 on both sides to perform synchronous up-and-down reciprocating motion. The servo electric cylinders 2-2 on both sides drive the crossbeam 1-4 and the pressure plate assembly 1-6 to perform synchronous up-and-down reciprocating motion. The pressure signal generated after pressurizing the umbrella canopy is transmitted to each pressure sensor 3-1-3. Each pressure sensor 3-1-3 collects data and feeds it back to the embedded driver 3-1-2. The PLC controller 3-1-1 processes the data and sends it to the control panel 3-2. It compares the data with preset parameters to realize the display and monitoring of information such as pressure and displacement.

[0078] The intelligent pressure sealing machine for headrest-type life-saving parachutes provided in this embodiment of the invention is designed with the concepts of "intelligentization, automation, and universality." The power source can provide pressure covering the existing pressurization range of headrest-type life-saving parachute boxes. It is equipped with a headrest-type parachute box protective plate and pressure plate assembly compatible with existing ones, achieving automatic pressurization of headrest-type life-saving parachutes in all states. Using power system 2 as the power source, it can provide stable, precise, and controllable pressure to the packaging machine through pulse-based directional control. Furthermore, by analyzing the technical parameters affecting the pressurization effect of the parachute, the control system collects and records pressure and displacement parameter signals. Human-machine interaction is achieved through control panel 3-2 and PLC controller 3-1-1. The operator inputs parameters and maintenance information through control panel 3-2, and control system 3 drives power system 2 to complete automatic operation. Simultaneously, a manual operation control mode is retained to allow for feedback and correction of control parameters based on packaging results. The intelligent pressure sealing machine provided in this embodiment of the invention has the following beneficial effects:

[0079] First, through the cooperative structure of the crossbeam 1-4, pressure plate assembly 1-6, and operating handle 1-5 in the main mechanical structure 1, the relative position of the pressure plate assembly 1-6 and the crossbeam 1-4 can be adjusted by the operating handle 1-5. This allows for the placement of the parachute box and canopy of the headrest-type life-saving parachute by changing the relative position of the pressure plate assembly 1-6 and the crossbeam 1-4, or the initial pressing of the canopy by the pressure plate assembly 1-6. Furthermore, the packaging protective plate and pressure plate assembly can be replaced according to different models of headrest parachute boxes, realizing an intelligent pressure sealing machine that integrates universality, automation, and digital intelligence.

[0080] Secondly, the servo-driven electric cylinders 2-2, symmetrically arranged on both sides of the power system, drive the crossbeam 1-4 and the pressure plate assembly 1-6 to synchronously perform up-and-down reciprocating motion, so that the pressure plate assembly 1-6 can pressurize and seal the headrest-type life-saving parachute placed in the parachute box 1-7. In addition, the servo motor 2-1 in the power system can provide a wider pressure range and facilitate the association with the control system. Furthermore, by adopting a pulse transmission frequency determined by the set upward and downward pressure speed, the entire control pulse speed is output according to a trapezoidal structure model, making the control process smooth, reliable, and accurate.

[0081] Third, through the configuration of the control system, on the one hand, technical parameters and maintenance information during the pressurization process can be set and recorded, and displayed on the screen or exported through the output interface, providing data support for the optimal pressurization scheme of various types of umbrellas; on the other hand, the current sealing pressure, screw displacement, and pressure holding time can be monitored in real time. When the system malfunctions, or the pressure or displacement exceeds the set standard value, the system alarm function will be triggered to ensure safety and reliability during use; furthermore, human-machine interaction can be achieved through the PLC controller and control panel to realize the standardization and automation control of the pressurization process; in addition, a dual mode of automatic operation and manual operation can be adopted. The parameter settings of automatic operation can be adjusted by judging the pressurization effect through manual operation, and the two-way feedback correction can obtain the optimal pressurization scheme for various types of umbrellas.

[0082] In summary, the technical solution provided by this utility model transforms the traditional, simple, mechanical, manual lifting and pressurizing process into an electrically automatic, intelligent lifting, pressurizing, and sealing process. It establishes standardized process parameters for the previously unquantifiable pressurizing process and uses a PLC controller to program different sealing stages, achieving automatic depressurization, timed pressure maintenance, and timely pressure release within a specified time. It also accurately records and displays pressure values, displacement values, working time values, and working curves at different times. By upgrading the pressure sealing process of the headrest-type life-saving parachute to a standardized and controllable maintenance process, it achieves precise pressurization, scientific pressure maintenance, and intelligent pressure release, effectively improving the quality and efficiency of pressure sealing and increasing the aircraft's flight cycle and sortie rate.

[0083] Based on the above-mentioned structure and control form of the intelligent pressure sealing machine for headrest-type life-saving umbrella provided by the embodiments of this utility model, in practical applications, when users use the intelligent pressure sealing machine, they should first check whether the accessories of the sealing machine are complete; adjust the locking pins so that the left, right and front guard plates are in the extended state.

[0084] The following describes how to use the intelligent pressure sealing machine for headrest-type life-saving parachutes provided in this embodiment of the invention:

[0085] Step 1: Rotate the crossbeam 1-4 to clear the upper space of the protective box 1-7; unscrew the accessories on the umbrella box, place the umbrella box on the wooden base of the protective box 1-7, and place the left, right and front protective panels on the left, right and front of the umbrella box respectively. Secure the protective panels to the umbrella box by rotating the locking screws; when tightening the left, right and front protective panels, keep the relative position of the center of the umbrella box and the center of the opening box basically consistent to prevent the umbrella box from being squeezed and deformed.

[0086] Step 2: Fold the life-saving parachute evenly in a "Z" shape and fill it into the parachute box. Pass the excess parachute canopy through the bottom of the guide tube 1-8. Rotate the crossbeam 1-4 to the pressurization position and tighten the locking pin to prevent the crossbeam 1-4 from rotating. By rotating the operating handle 1-5, the pressure plate presses on the parachute canopy inside the guide tube 1-8 to achieve initial compression of the parachute canopy.

[0087] Step 3: Click the power switch on control panel 3-2 to power on the intelligent pressure sealing machine. Pressure sealing can be performed in both manual and automatic operation modes, as explained below:

[0088] In manual operation mode, select the parachute model on the touch screen; press and hold the "Press Down" button on the control panel until the pressure plate descends and reaches the parachute sealing state, then release the "Press Down" button and maintain the sealing pressure as needed; after the pressure maintenance is completed, press and hold the "Rise" button until the pressure plate rises to the initial position, then release the "Rise" button to complete the pressure sealing process.

[0089] In automatic operation mode, select the life-saving parachute model on control panel 3-2, enter the optimal pressurization parameters (only when packaging this type of parachute for the first time), operator information, etc., and click the "Press Down" button. The pressure plate will descend and press down; once the life-saving parachute is in the pressure-sealing state, it will automatically enter the pressure-holding state; once the pressure holding ends, the pressure plate will automatically rise to the initial position, completing the pressure sealing process.

[0090] The intelligent pressure sealing machine provided in the above embodiments of this utility model represents a transformation from a previously singular mechanical structure to a digitally intelligent general-purpose equipment. It employs an integrated control system, using a servo driver to convert the control system's electrical signals into working signals for the servo motor. The servo motor mechanically drives the servo electric cylinder to perform reciprocating motion, enabling pressure sealing of various models and headrest-type life-saving umbrellas. The control system can collect parameters such as pressure and displacement, and features one-button start / stop, real-time data transmission, and system alarm recording functions. This provides significant engineering practical value for the development of digitally intelligent and automated general-purpose sealing equipment.

[0091] In summary, the core of this utility model lies in changing the traditional simple mechanical manual lifting and pressurizing process into an electric automatic intelligent lifting, pressurizing and sealing process. It establishes unified standard process parameters for the original unquantifiable pressurizing process and integrates related equipment to realize the digitalization, automation and standardization of the pressure sealing process of the headrest-type life-saving parachute.
