Description

Technical Field

[0001] The utility model relates to the technical field of simulation training platforms, in particular to a bracket structure of a helicopter take-off and landing training platform. Background Art

[0002] The Helicopter Landing Training Platform is a land-based platform that can simulate the motion of a ship's deck under various sea conditions, providing a dynamic platform for helicopter landing training. It can also serve as a fixed training platform, providing fixed-mode helicopter landing training. Pilots can use the platform to simulate ship motion under various sea conditions for landing training, achieving training objectives, improving training quality, reducing training costs, shortening training cycles, and also enhancing the quality of military training equipment.

[0003] The helicopter landing training platform (abbreviated as the landing platform) is an important component of the helicopter landing training platform and is used for helicopter landing training. The lower part of the landing platform is a swing platform, which is connected to the drive unit and the follower support device, so that the swing platform can drive the movement of the entire landing platform.

[0004] Current landing platform supports primarily consist of several steel decks connected by bolts and welds. The entire landing platform and the swing platform can only be connected via partial welding. This results in a weak connection between the two platforms, and welds can break during the platform's long-term swinging motion. Furthermore, these platforms require large amounts of raw materials, have long production cycles, high production costs, and are difficult to install on-site. Most importantly, the swinging effect provides uneven support for the platform, potentially leading to uneven power output for the drive units and shortening the life of some of the drive units. Utility Model Content

[0005] The utility model mainly solves the technical problems that the connection strength between the current landing platform and the swing platform is weak, and the welds may break during the long-term swinging movement of the landing platform. A bracket structure of the helicopter take-off and landing training platform is proposed to improve the support and load-bearing capacity of the helicopter take-off and landing training platform.

[0006] The utility model provides a support structure for a helicopter take-off and landing training platform, comprising: a central hexagonal beam, a main beam, a take-off and landing area reinforcement beam, a transverse inner contour beam, a longitudinal inner contour beam, an outer contour beam, a transition beam and an edge connection beam;

[0007] The central hexagonal beam is located at the center of the support structure. The central hexagonal beam is in the shape of a regular hexagon, and a central barrel is provided at the center of the central hexagonal beam. The six corners of the central hexagonal beam are respectively connected to the six main beams.

[0008] A plurality of take-off and landing area reinforcement beams are arranged on the outer side of the central hexagonal beam, and a mesh hexagonal structure is formed between the plurality of take-off and landing area reinforcement beams, the six main beams, the transverse inner contour beams and the six sides of the central hexagonal beam;

[0009] The edge connecting beams are arranged at the outermost circle of the support structure, and the edge connecting beams form a rectangular frame;

[0010] The inner circle of the edge connecting beam is provided with an outer contour beam; a plurality of transition beams are connected between the edge connecting beam and the outer contour beam;

[0011] A plurality of transverse inner profile beams and a plurality of longitudinal inner profile beams are distributed between the outer profile beam and the meshed hexagonal structure.

[0012] Preferably, it also includes: three electric cylinder connecting seats;

[0013] The three electric cylinder connection seats are distributed at the bottom of the spaced main beams, and the three electric cylinder connection seats are spaced 120 degrees apart.

[0014] Preferably, it also includes: sixteen follow-up system connection seats;

[0015] Sixteen follower system connecting seats are respectively fixed on the bottom of the transverse inner contour beam and the outer contour beam.

[0016] Preferably, it further comprises: twelve fixed supports;

[0017] The twelve fixed supports are respectively fixed on the horizontal inner profile beam, the longitudinal inner profile beam and the bottom of the main beam.

[0018] Preferably, the main beam is formed by welding steel plates, the cross-section of the main beam is rectangular, and there are reinforcing ribs inside the main beam.

[0019] Preferably, the height of the main beam decreases from the inside to the outside.

[0020] Preferably, the transverse inner profile beam, the longitudinal inner profile beam, and the take-off and landing area reinforcement beam are respectively welded by steel plates;

[0021] The cross-sections of the transverse inner profile beam, longitudinal inner profile beam, and take-off and landing area reinforcement beam are rectangular;

[0022] The transverse inner profile beam, the longitudinal inner profile beam and the take-off and landing area reinforcement beam are internally provided with reinforcing ribs.

[0023] Preferably, the cross-section of the transition beam is in the shape of an I, and the height of the transition beam decreases from the inside to the outside.

[0024] The utility model provides a support structure for a helicopter take-off and landing training platform. Through flexible structural combination, the weight of the entire support is reduced, material consumption is saved, and the difficulty of on-site installation is reduced while ensuring that the overall load-bearing requirements remain unchanged. This support structure is divided into a dynamic load area, a static load area, and a light load area based on the usage characteristics of the helicopter take-off and landing training platform. The center of gravity of the entire support structure is concentrated as much as possible within the range of the power support, so that the overall structure has higher strength and rigidity, improves the support and load-bearing capacity of the helicopter take-off and landing training platform, extends its service life, and increases safety. At the same time, through structural adjustment, the weight distribution in the edge area of ​​the platform is reduced, thereby reducing the inertia of the edge of the platform during movement, making the entire movement process more stable.

[0025] This utility model meets the requirements of the landing platform's strength and rigidity, achieving uniform weight distribution. A deck can be mounted on the support structure, with the support structure and deck jointly supporting the landing platform, ensuring stable and uniform load bearing. The lower portion of the support structure is connected to a drive device and a follower support device, enabling the entire landing platform to move, providing support for realistically simulating the roll, pitch, heave, and other motions of a ship's deck under various sea conditions.

It should be understood that the specific embodiments described herein are merely intended to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, rather than all of its contents.

[0030] like Figure 1-2As shown, an embodiment of the present invention provides a support structure for a helicopter take-off and landing training platform, comprising: a central hexagonal beam 1, a main beam 2, a take-off and landing area reinforcement beam 3, a transverse inner contour beam 4, a longitudinal inner contour beam 5, an outer contour beam 6, a transition beam 7 and an edge connecting beam 8.

[0031] The central hexagonal beam 1 is located at the center of the support structure. The central hexagonal beam 1 is a regular hexagon, and a central barrel is opened in the center of the central hexagonal beam 1. The central barrel is a reserved installation position for the lowering grid; the six sides of the central hexagonal beam 1 are connected to the central barrel with reinforcing ribs.

[0032] The six corners of the central hexagonal beam 1 are connected to six main beams 2, each of which is fixedly connected to the outer contour beam 6. The main beams 2 are welded from steel plates, have a rectangular cross-section, and are internally reinforced with ribs. The height of the main beams 2 decreases from the inside outward, thereby transferring force toward the center.

[0033] Multiple landing zone reinforcement beams 3 are positioned outside the central hexagonal beam 1. These beams, the six main beams 2, the transverse inner profile beams 4, and the six sides of the central hexagonal beam 1 form a hexagonal mesh structure. The landing zone reinforcement beams 3 are short, inclined beams, totaling 16.

[0034] The edge connecting beams 8 are arranged at the outermost circle of the support structure, and the edge connecting beams 8 form a rectangular frame.

[0035] The inner ring of the edge connecting beams 8 is provided with outer profile beams 6, forming a rectangular frame. The edge connecting beams 8 primarily support the top deck. Multiple transition beams 7 connect between the edge connecting beams 8 and the outer profile beams 6. Each transition beam 7 has an I-shaped cross-section, and its height decreases from the inside outward to transfer forces to the outer profile beams. There are 28 transition beams 7.

[0036] Distributed between the outer profile beam 6 and the hexagonal mesh structure are multiple transverse inner profile beams 4 and multiple longitudinal inner profile beams 5. Specifically, there are six transverse inner profile beams 4: two upper and lower beams located inside the two transverse sides of the outer profile beam 6 (connected between the two longitudinal sides of the outer profile beam 6), and four beams located on the upper and lower sides of the transverse main beam 2 (connected between one longitudinal side of the outer profile beam 6 and the inclined main beam 2). There are four longitudinal inner profile beams 3, all parallel to the longitudinal sides of the outer profile beam 6: two connected between the two transverse sides of the outer profile beam 6, and two connected between one transverse side of the outer profile beam 6 and the hexagonal mesh structure.

[0037] The transverse inner profile beam 4, the longitudinal inner profile beam 5, and the take-off and landing area reinforcement beam 3 are respectively welded from steel plates; the cross-sections of the transverse inner profile beam 4, the longitudinal inner profile beam 5, and the take-off and landing area reinforcement beam 3 are rectangular; the transverse inner profile beam 4, the longitudinal inner profile beam 5, and the take-off and landing area reinforcement beam 3 have reinforcing ribs inside.

[0038] The support structure of the helicopter takeoff and landing training platform of the present invention also includes three electric cylinder connectors 9 , which are distributed at intervals on the bottom of the main beam 2 and spaced 120 degrees apart. The electric cylinder connectors 9 are used to connect to the electric cylinder of the drive device.

[0039] The support structure of the helicopter takeoff and landing training platform of the present invention also includes a plurality of servo system connectors 10, each secured to the bottom of the inner transverse profile beam 4 and the outer transverse profile beam 6. These connectors 10 are used to connect to the servo device. Specifically, there are 16 servo system connectors 10.

[0040] The support structure of the helicopter takeoff and landing training platform of the present invention also includes a plurality of fixed supports 11, each of which is fixed to the bottom of the transverse inner profile beam 4, the longitudinal inner profile beam 5, and the main beam 2. These fixed supports 11 cooperate with the fixed support system, making surface contact with the fixed support system, providing support but not connection. Specifically, there are twelve fixed supports 11: four fixed to the bottom of the transverse inner profile beam 4, four to the bottom of the longitudinal inner profile beam 5, and four to the bottom of the inclined main beam 2.

[0041] The support structure of this helicopter takeoff and landing training platform is divided into a dynamic load zone (the hexagonal mesh structure), a static load zone (the area within the outer contour beam 6), and a light load zone (the area between the outer contour beam 6 and the edge connecting beam 8). The center of gravity of the entire support structure is concentrated as much as possible within the dynamic support range, ensuring high overall strength and rigidity.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications to the technical solutions described in the above embodiments, or equivalent replacement of some or all of the technical features therein, do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
