Description

Technical Field

[0001] This invention belongs to the field of parachute stacking technology, specifically relating to a parachute shaping fixture, parachute shaping method and system. Background Technology

[0002] Currently, during flights equipped with parachutes, the parachute must be loaded into a fixed position with a specific volume before flight. During flight, the parachute canopy and lines must be kept neatly shaped and free from knots, crosses, or disordered layering. When the parachute needs to be deployed, the folded and shaped canopy and lines can be opened sequentially and inflated layer by layer, ensuring a uniform impact load and preventing damage to the parachute. Furthermore, when not in use, the parachute must be folded and shaped for storage to prevent rebound and loosening, achieving long-term storage.

[0003] However, current parachute shaping mainly relies on manual operation, lacks standardized tools, and is difficult to maintain. After the parachute is stacked, the parachute pack is easily deformed due to vibration and compression during transportation or storage, requiring repeated adjustments and increasing maintenance costs. Summary of the Invention

[0004] The main objective of this invention is to provide a parachute shaping fixture, which aims to solve the problems of existing parachute shaping mainly relying on manual operation, lacking standardized tools, making it difficult to maintain the shape, and causing the parachute pack to deform due to vibration and compression during transportation or storage after being stacked, requiring repeated adjustments and increasing maintenance costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides a parachute shaping fixture, comprising: Pressure plates are used to compress parachutes into a fixed volume under external force. The fixing plate is used to fix the entrance of the rigid fixture after the parachute has been shaped; A transparent cylinder for holding the parachute; Connector for connecting the transparent cylinder and the rigid fixture; The rigid fixture is used to load the shaped parachute; The transparent cylinder and the rigid fixture are connected by the connector, and the parachute volume is compressed by the pressure plate and compressed into the rigid fixture. The entrance of the rigid fixture is fixed by the fixing plate.

[0006] Furthermore, the rigid fixture is hollow and includes a first flange, a second flange, and a rigid fixture body; The first flange and the second flange are respectively placed at both ends of the rigid fixture body and are stabilized by triangular reinforcing ribs.

[0007] Furthermore, the connector is hollow and has a predetermined number of threaded holes at its lower end; The upper end of the connector is sleeved with the transparent cylinder, and the lower end is connected to the second flange of the rigid fixture by screws.

[0008] Furthermore, the transparent cylinder is made of a transparent material.

[0009] Furthermore, the pressure plate is provided with threaded holes for external equipment to apply pressure to shape the parachute, and the fixing plate is provided with threaded holes corresponding to the second flange for fixing the rigid fixture inlet after the parachute is shaped.

[0010] Furthermore, to achieve the above objectives, the present invention also provides a parachute shaping method based on a parachute shaping fixture, wherein the parachute shaping method specifically includes: The parachute shaping fixture is pre-assembled in a first manner. When the target parachute is loaded into the transparent cylinder, the pressure plate is controlled by an external device to apply pressure to the target parachute. When the target parachute is pressed into the rigid fixture, the connector and the rigid fixture are separated, and the fixing plate is fixed to the rigid fixture through the second flange.

[0011] Furthermore, the pre-assembly of the parachute shaping fixture in a first manner specifically includes: The transparent cylinder and the rigid fixture are pre-connected via the connector to obtain a parachute shaping fixture assembled in a first manner.

[0012] Furthermore, to achieve the above objectives, the present invention also provides a parachute shaping system, the parachute shaping system comprising: A shaping module is used to pre-assemble the parachute shaping fixture in a first manner. When the target parachute is loaded into the transparent cylinder, the pressure plate is controlled by an external device to apply pressure to the target parachute. A fixing module is used to separate the connector and the rigid fixture when the target parachute is pressed into the rigid fixture, and to fix the fixing plate onto the rigid fixture via the second flange.

[0013] This invention relates to a parachute shaping fixture, comprising a pressure plate for compressing a parachute into a fixed volume under external force; a fixing plate for fixing the entrance of a rigid fixture after the parachute has been shaped; a transparent cylinder for holding the parachute; and a connector for connecting the transparent cylinder and the rigid fixture. The rigid fixture is used to load the shaped parachute. The transparent cylinder and the rigid fixture are connected by the connector, and the parachute is compressed into the rigid fixture by the pressure plate. The entrance of the rigid fixture is then fixed by the fixing plate. Compared with existing technologies, this invention allows for external pressure applied to the parachute during shaping using a parachute shaping fixture, and the fixing plate secures the shaped parachute after shaping. This process replaces manual operation with the parachute shaping fixture, resulting in a more stable shaped parachute. The shaped parachute is stored in the rigid fixture by the fixing plate, ensuring it does not deform during transportation and storage, thus reducing maintenance costs. Attached Figure Description

[0024] Currently, during parachute flights, the parachute needs to be loaded into a fixed position with a specific volume before flight. During flight, the parachute canopy and lines must be kept neatly shaped and free from knots, crosses, or disordered layering. When deployment is needed, the folded and shaped canopy and lines can be opened sequentially and inflated layer by layer, ensuring a uniform impact load and preventing damage. Furthermore, when not in use, the parachute needs to be folded and shaped for storage to prevent rebound and loosening, allowing for long-term storage. However, current parachute shaping relies primarily on manual operation, lacking standardized tools, making shape maintenance difficult. The folded parachute pack is prone to deformation during transportation or storage due to vibration and compression, requiring repeated adjustments and increasing maintenance costs.

[0025] To address one or more of the above-mentioned problems, the present invention provides a parachute shaping fixture, such as... Figure 1 and Figure 2 As shown, it includes: a pressure plate 1, used to compress the parachute into a fixed volume under external force; a fixing plate 2, used to fix the inlet of the rigid fixture 5 after the parachute has been shaped; a transparent cylinder 3, used to hold the parachute; a connector 4, used to connect the transparent cylinder 3 and the rigid fixture 5; the rigid fixture 5 is used to load the shaped parachute; wherein, the transparent cylinder 3 and the rigid fixture 5 are connected by the connector 4, the volume of the parachute is compressed by the pressure plate 1, the parachute is compressed into the rigid fixture 5, and the inlet of the rigid fixture 5 is fixed by the fixing plate 2.

[0026] In one embodiment of the present invention, the pressure plate 1 is circular and is used to apply pressure to the parachute. In this invention, the pressure plate 1 is provided with corresponding threaded holes for connection to external equipment. This allows the external equipment to apply pressure to the stacked parachute, pressing it into the rigid fixture 5 to complete the shaping process. Preferably, the pressure plate 1 has a centrally located threaded hole, and four identical threaded holes are evenly and symmetrically distributed along the central threaded hole, facilitating the connection between the external equipment and the pressure plate 1 and enabling pressure control. In one embodiment of the present invention, the corresponding external equipment can be a hydraulic or automated pressure device. Further, in this invention, the radius of the pressure plate 1 is set according to the inner diameter of the transparent circular hole, i.e., the radius of the pressure plate 1 is not significantly different from the inner diameter of the transparent circular hole. This ensures that the pressure plate 1 can transitionally fit and press against the transparent cylinder 3 under external pressure. After the pressure plate 1 is pressed in, its outer circumferential surface tightly adheres to the inner wall of the transparent cylinder 3, ensuring that pressure is applied evenly and stably to the parachute, resulting in a more stable shaped parachute.

[0027] Further, in one embodiment of the present invention, the fixing plate 2 is circular, and the fixing plate 2 is provided with threaded holes corresponding to the second flange 51 for fixing the entrance of the rigid fixture 5 after the parachute is shaped. That is, in the present invention, the fixing plate 2 has a central hole and an opening on one side, the opening communicating with the central hole of the fixing plate 2, facilitating the removal of the fixing plate 2. Further, the threaded holes are evenly distributed on the fixing plate 2, and the distribution position of the threaded holes is the same as that of the threaded holes on the second flange 51, so as to ensure that after the parachute is pressed into the rigid fixture 5, the fixing plate 2 can be fixed to the rigid fixture 5 by screws and nuts, thereby allowing the parachute loaded in the rigid fixture 5 to maintain a stable shape and not deform. Further, in the present invention, the threaded holes on the fixing plate 2 are set on the edge of the fixing plate 2, that is, the radius of the fixing plate 2 is the same as the maximum outer radius of the flange of the second flange 51, so that the fixing plate 2 can be stably fixed to the rigid fixture 5.

[0028] In one embodiment of the present invention, the corresponding transparent cylinder 3 is made of a transparent material, and further preferably a high-strength transparent material, including modified acrylic, transparent nylon, etc. The transparent cylinder 3, being made of a transparent material, allows for real-time observation of the parachute's condition during the shaping process, enabling timely adjustments in case of problems, without the need for re-deploying and shaping after complete shaping, thus saving shaping time.

[0029] In one embodiment of the present invention, the connector 4 is hollow and has a predetermined number of threaded holes at its lower end. The upper end of the connector 4 is sleeved with the transparent cylinder 3, and the lower end is connected to the rigid fixture 5 via screws to the second flange 51 of the rigid fixture 5. The connector 4 is a flange with a cylinder at its upper end. The inner diameter of the cylinder at the upper end of the connector 4 is larger than the inner diameter of the flange. Threaded holes are evenly distributed between the outer circle of the cylinder and the flange and the outermost part of the flange according to the first flange 53, so that the connector 4 can be fixedly connected to the rigid fixture 5 by screws and nuts. The upper end of the connector 4 is inserted into the transparent cylinder 3, that is, the inner diameter of the cylinder at the upper end of the connector 4 is close to the outer diameter of the transparent cylinder 3, so that the outer wall of the transparent cylinder 3 and the inner wall of the cylinder at the upper end of the connector 4 can fit tightly. Since the inner diameter of the flange on the connector 4 is smaller than the inner diameter of the cylinder on the connector 4, the transparent cylinder 3 will be placed on the flange of the connector 4.

[0030] Further, in one embodiment of the present invention, the rigid fixture 5 is hollow and includes a first flange 53, a second flange 51, and a rigid fixture body 52; wherein the first flange 53 and the second flange 51 are respectively placed at both ends of the rigid fixture body 52 and are stabilized by triangular reinforcing ribs. The first flange 53 is located at the bottom of the rigid fixture 5, and the second flange 51 is located at the top of the rigid fixture 5. The bottom of the first flange 53 is not perforated. Both the first flange 53 and the second flange 51 are square chamfered flanges. Two triangular mounting holes are provided in the square portions of both the first flange 53 and the second flange 51. Triangular reinforcing ribs are symmetrically and evenly arranged at the connection points between the first flange 53 and the second flange 51 and the rigid fixture body 52. ​​In one embodiment of the present invention, eight triangular reinforcing ribs are provided on both the first flange 53 and the second flange 51.

[0031] Furthermore, in one embodiment of the present invention, the connector 4 and the second flange 51 are fixedly connected by screws and nuts. When the connector 4 is connected to the first flange 53, the transparent cylinder 3, the connector 4, and the rigid fixture 5 are connected together. The parachute is placed into the transparent cylinder 3, and the parachute is shaped by the pressure plate 1. When the parachute is pressed into the rigid fixture 5, the connector 4 and the transparent cylinder 3 are removed, and the fixing plate 2 and the second flange 51 are fixedly connected by screws and nuts, thus completing the shaping of the parachute.

[0032] The parachute shaping fixture of the present invention includes a pressure plate 1 for compressing the parachute into a fixed volume under external force; a fixing plate 2 for fixing the inlet of a rigid fixture 5 after the parachute has been shaped; a transparent cylinder 3 for holding the parachute; a connector 4 for connecting the transparent cylinder 3 and the rigid fixture 5; and the rigid fixture 5 for loading the shaped parachute. The transparent cylinder 3 and the rigid fixture 5 are connected by the connector 4, the parachute volume is compressed by the pressure plate 1 to compress the parachute into the rigid fixture 5, and the inlet of the rigid fixture 5 is fixed by the fixing plate 2. Compared with the prior art, the present invention uses a parachute shaping fixture to apply pressure to the parachute to be shaped by external equipment and pressure plate 1 during the parachute shaping process, and fixes the shaped parachute by fixing plate 2 after shaping. In this process, the parachute shaping fixture replaces manual operation, thereby making the shaped parachute more stable. The shaped parachute is stored in a rigid fixture 5 by fixing plate 2, which can ensure that it will not be deformed during transportation and storage, and reduce maintenance costs.

[0033] This invention also provides a parachute shaping method based on a parachute shaping fixture. The preferred embodiment of this invention describes a parachute shaping method, such as... Figure 3 As shown, the parachute shaping method includes the following steps: Step S10: The parachute shaping fixture is pre-assembled in a first manner. When the target parachute is loaded into the transparent cylinder 3, the pressure plate 1 is controlled by an external device to apply pressure to the target parachute. Step S20: When the target parachute is pressed into the rigid fixture 5, the connector 4 and the rigid fixture 5 are separated, and the fixing plate 2 is fixed to the rigid fixture 5 through the second flange 51.

[0034] Specifically, in this invention, when the parachute shaping fixture is assembled in the first manner, the shaping process of the target parachute is carried out; when the parachute shaping fixture is assembled in the second manner, the shaping process of the target parachute is completed and the corresponding packaging is performed.

[0035] Furthermore, the pre-assembly of the parachute shaping fixture in a first manner specifically includes: pre-connecting the transparent cylinder and the rigid fixture 5 through the connector 4 to obtain the parachute shaping fixture assembled in the first manner.

[0036] Specifically, in this invention, the first method of assembly involves fixing the transparent cylinder 3, the connector 4, and the rigid fixture 5 in sequence, while the second method of assembly involves fixing the transparent cylinder 3 and the fixing plate 2 together.

[0037] like Figure 4As shown, based on the above-described parachute shaping method, the present invention also provides a parachute shaping system, wherein the parachute shaping system includes: The shaping module 111 is used to pre-assemble the parachute shaping fixture in a first manner. When the target parachute is loaded into the transparent cylinder 3, the pressure plate 1 is controlled by an external device to apply pressure to the target parachute. The fixing module 112 is used to separate the connector 4 and the rigid fixture 5 when the target parachute is pressed into the rigid fixture 5, and to fix the fixing plate 2 onto the rigid fixture 5 through the second flange 51.

[0038] The present invention also provides a computer-readable storage medium, wherein the computer-readable storage medium stores a parachute shaping program, which, when executed by a processor, implements the steps of the parachute shaping method as described above.

[0039] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention should be considered as equivalent substitutions and are included within the protection scope of the present invention.
