Description

Technical Field

[0001] The utility model belongs to the field of aviation assembly technology and relates to an antenna hanging device. Background Art

[0002] Final assembly is the process of assembling all aircraft parts and finished products together to form a complete whole. After the aircraft parts enter the final assembly stage and the major parts are connected, the installation of the aircraft subsystems will be carried out.

[0003] Once the major parts of the aircraft are docked, the aircraft is lifted up by a jack. At this time, the aircraft is about 4 to 5 meters from the ground, and the back of the fuselage is 7 to 8 meters from the ground. The assembly of finished parts on the back of the fuselage is a high-altitude operation, and because the shape of the aircraft's longitudinal section is close to a perfect circle, there is a certain risk in completing the assembly of related systems on the back of the fuselage.

[0004] The dimensions of a certain type of antenna are shown in the attached Figure 1 As shown, its weight is close to 50Kg. The antenna is installed at the long stringer 55 of the frame 37-38 on the back of the fuselage. The antenna is unpacked, installed on the machine, and assembled. There are certain risks for the assemblers. Therefore, an auxiliary lifting device needs to be designed to solve the problem of difficult installation of the antenna. Utility Model Content

[0006] The technical solution of this utility model:

[0007] An antenna hanging device includes a device tray and a hanging beam structure, wherein the device tray and the hanging beam structure are connected, the device tray includes a chassis, the chassis is provided with two symmetrical load-bearing plates along the length direction, a pin-pressing plate structure is provided on the load-bearing plate, the bottom plate is provided with an antenna positioning hole along the width direction, a positioning bolt is provided in the antenna positioning hole, and the antenna can be fixed on the chassis by means of the two pin-pressing plate structures and the positioning bolt.

[0008] Furthermore, the pin-pressing plate structure includes a pin arranged on the chassis and a fixed pressing plate arranged on the pin. The height of the fixed pressing plate on the pin can be adjusted according to the thickness of different parts of the antenna.

[0009] Furthermore, the chassis is a structure with a hollow center.

[0011] Furthermore, the hanging beam structure includes a hook, a steel cable, and a cross beam, and the chassis is connected to the lower end of the cross beam through a hanging ring, a hook, and a steel cable.

[0012] Furthermore, the upper end of the beam is connected to the crane through a hanging ring, a steel cable and a hook.

[0023] The present invention will be further described below in conjunction with the accompanying drawings:

[0024] The dimensions of a certain type of antenna are shown in the attached Figure 1As shown, its weight is close to 50Kg. The antenna is installed at the long stringer 55 of the frame 37-38 on the back of the fuselage. The antenna is unpacked, installed on the machine, and assembled. There are certain risks for the assemblers. Therefore, an auxiliary lifting device needs to be designed to solve the problem of difficult installation of the antenna.

[0025] like Figure 1-3 As shown, the utility model proposes an antenna hanging device, including a device tray and a hanging beam structure, the device tray and the hanging beam structure are connected, the device tray includes a chassis 5, the chassis 5 is provided with two symmetrical load-bearing plates 6 along the length direction, the load-bearing plates 6 are provided with a pin-pressing plate structure, the bottom plate is provided with an antenna positioning hole 7 along the width direction, the antenna positioning hole 7 is provided with a positioning bolt, and the antenna can be fixed on the chassis 5 by the two pin-pressing plate structures and the positioning bolt.

[0026] The non-fixed parts of the antenna will rotate about the central axis of the antenna, and there are a large number of components, cables, and traveling wave tubes on the antenna that are exposed, which can easily cause damage to the antenna itself during the hoisting process. In addition, the antenna itself has no hanging points. Therefore, the present invention considers hoisting the antenna in the form of chassis consignment during the design process to avoid damage to the antenna during hoisting.

[0027] Based on the characteristics of the antenna, the hanging shape structure is determined: the weight of this type of antenna is 50kg, but the shape is irregular and the size is large: about 800×600×400. After analyzing the antenna structure through the antenna digital model, the antenna is roughly symmetrical, and its center of gravity position coordinates are approximately (0,0,105). There are 300×140 plane areas on both sides of the bottom that can be used for support. According to the results of the antenna digital model analysis, the bottom of the antenna is a circular plane. By selecting the large plane at the bottom of the antenna as its supporting surface on the support frame, the antenna is stable and has a good stress state. Therefore, the device tray and chassis 5 are designed. After the antenna is placed securely on the chassis 5, it is hoisted together with the chassis 5. The chassis 5 is a hollow structure in the center, which is convenient for weight reduction; the chassis 5 is provided with a storage box 8 for storing the pins 3, the pressure plate 4, and the screws, which is convenient for the storage of the hoisting device.

[0028] Taking into account the problem that the antenna may slip or fall during the hoisting and transportation process, the present invention sets an antenna positioning hole 7 on the chassis 5. The antenna positioning hole 7 corresponds to the position of the structural hole on the antenna. By installing a screw and a nut, the antenna and the chassis 5 are positioned and pressed to ensure that the antenna will not be directly detached from the hoisting device and fall.

[0029] In order to ensure that the antenna does not slide sideways and take into account the ease of connection and disassembly between the antenna and the chassis 5, a pin-pressing plate structure is set on the load-bearing plates 6 on the two outer sides of the chassis of the lifting device. The two fixed pressing plates 4 are manually rotated to assist in pressing the antenna. The pin-pressing plate structure includes a pin 3 set on the chassis and a fixed pressing plate 4 set on the pin. The fixed pressing plate 4 can adjust the height of the fixed pressing plate 4 on the pin 3 according to the thickness of different parts of the antenna.

[0030] When designing the hoisting device, a hanging beam structure is also set up. The hanging beam structure includes a hook 1, a steel cable 2, and a crossbeam 10. The device chassis 5 is connected to the lower end of the crossbeam 10 through a hanging ring 9, a hook 1, and a steel cable 2. The upper end of the crossbeam 10 is connected to the crane through a hanging ring 9, a steel cable 2, and a hook 1. The crossbeam 10 in the hanging beam structure is used to ensure stable transportation of the antenna, and the crossbeam 10 ensures that the steel cable will not be directly overlapped on the surface of the antenna during hoisting to cause damage to the antenna components.
