Description

Technical Field

[0001] This utility model belongs to the field of aviation technology and relates to a device for fixing heavy random rods on an aircraft panel. Background Technology

[0002] A certain type of aircraft has an antenna radome on the lower part of its nose. To avoid interference between the airport's standard straight tow bar and the radome, a specially designed three-bar tow bar is used. Both ends are straight, while the middle bar is curved. Therefore, during aircraft transfers, this specially designed tow bar needs to be disassembled into three sections and carried along. The tow bar is ground equipment with smooth surfaces, and even after being disassembled into three sections, it remains long and heavy. Using parallel brackets to install it on the cabin floor significantly occupies the limited space available for equipment placement. Using a double-layer stacking method reduces the lateral space occupied by the tow bar, but increases the center of gravity height, requiring reinforcement at the connection between the brackets and the floor frame. The tow bar mounting bracket uses a combination of upper and lower brackets, increasing its own weight. Furthermore, a protective cover is needed to ensure the safety of onboard personnel and prevent accidental damage to the tow bar. Installing the tow bar on the cabin floor occupies limited usable space, severely hindering onboard personnel movement and equipment installation, increasing the weight of the fuselage structure and manufacturing costs. Therefore, reducing installation and disassembly time and improving work efficiency are crucial. Utility Model Content

[0003] Purpose of the utility model: This utility model overcomes the shortcomings of the prior art and provides a reasonable, reliable, efficient, lightweight, low-center-of-gravity, and low-cost rod installation bracket, which solves problems such as restricted movement of onboard personnel and effective utilization of the work cabin.

[0004] Technical solution: A device for fixing heavy, irregularly shaped rods on an aircraft wall panel, mainly including brackets 1, struts 2, columns 3, and tethering rings 5. The brackets 1 are installed in groups on the fuselage wall panel frame to provide support for the rods. The struts 2 are used to connect the brackets to the stringers or skin in front of or behind the brackets 1 to provide longitudinal support for the brackets 1. Each bracket web is designed with a mounting hole for installing the tethering ring. The web of the bracket is connected to the frame to provide support for the rods and their overload.

[0005] Furthermore, all brackets 1 are integrally machined parts. The arc-shaped stiffening plate on the upper part of the bracket 1 along the rod axis and the stiffening plates on both sides form a closed box-shaped part. A vertical stiffening rib is added in the middle of the stiffening plates on both sides. The direction of the vertical stiffening rib is the same as that of the stiffening plates on both sides. This is used to increase the rigidity of the box-shaped part and the connection of the support rod 2. The curved stiffening plate on the upper part of the bracket 1 along the rod axis is designed with a flange perpendicular to the rod axis. This is used to limit the binding rope of the traction rod in the lateral direction.

[0006] Furthermore, the bracket 1 is divided into bracket I1a, bracket II1b, bracket III1c, bracket IV1d, bracket VI1e, bracket VII1f, bracket VIII1g, and bracket IX1h. Bracket I1a and bracket II1b form a group of brackets for installing and fixing short straight rods; bracket III1c, bracket IV1d, and bracket VI1e form a group of brackets for installing and fixing long straight rods; and bracket VII1f, bracket VIII1g, and bracket IX1h form a group of brackets for installing and fixing curved rods.

[0007] Furthermore, each of the brackets I1a, II1b, III1c, VI1e, VII1f, and IX1h has a mounting hole for a tethering ring 5 on its web surface, and the web surface of each bracket is connected to the frame to provide support for the rod and its overload.

[0008] Furthermore, the support rod 2 is divided into support rod I 2a and support rod II 2b. Support rod I 2a is an L-shaped profile used to connect the middle vertical rib of the support 1 to the long stringer. Support rod II 2b is a trapezoidal sheet metal bending piece used to connect the column 3 and the fuselage skin.

[0009] Furthermore, the column 3 is used to connect the bracket 1, the frame and the strut Ⅱ2b, providing longitudinal support for the bracket 1.

[0010] Furthermore, it also includes an anti-wear pad, which is attached to the upper surface of the upper curved vertical rib of the bracket 1 to prevent the rod and the bracket 1 from rubbing against each other and to increase the coefficient of friction between the rod and the bracket 1.

[0011] Furthermore, the tethering ring 5 is used to secure the longitudinal binding rope.

[0012] Furthermore, the auxiliary binding rope is used to bind the support 1 to the rod in the lateral and longitudinal directions, transferring the vertical and horizontal loads of the rod to the support 1 and preventing the rod from sliding.

[0013] Technical Effects: This utility model provides a device for fixing heavy, random rods on aircraft panels. When a rod needs to be moved, it can be secured to a bracket using both binding ropes and hook-attached ropes, providing a simple and convenient platform for rod installation and removal. This structural improvement essentially does not alter the original panel structure; the rod can be disassembled and installed simply by removing and attaching the binding ropes and hook-attached ropes.

[0024] To more clearly illustrate the technical solutions of the embodiments of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings or specific implementation examples. It should be noted that some (but not all) of the disclosed examples are shown in the drawings. In fact, many different examples can be described, and these examples should not be construed as limited to the examples set forth herein. Rather, these examples are described to better demonstrate the positive effects of this utility model, and all aspects not detailed herein are considered to be well-known or conventional techniques in the art.

[0025] See appendix Figures 1-9 Specifically, a pole installation and fixing device is provided, including eight brackets, eight support poles, two columns, eight anti-wear pads, six tie rings, fourteen binding ropes, and six tie ropes with hooks;

[0026] All brackets 1 are integrally machined parts. The arc-shaped stiffening plate on the top of bracket 1 along the rod axis and the stiffening plates on both sides form a closed box-shaped part. A vertical stiffening rib is added in the middle of the stiffening plates on both sides. The direction of the vertical stiffening rib is the same as that of the stiffening plates on both sides. This is used to increase the rigidity of the box-shaped part and the connection of the support rod 2. The curved stiffening plate on the top of bracket 1 along the rod axis is designed with a flange perpendicular to the rod axis. This is used to limit the binding rope of the traction rod in the lateral direction.

[0027] The bracket 1 is divided into brackets I1a, II1b, III1c, IV1d, VI1e, VII1f, VIII1g, and IX1h. Brackets I1a and II1b form a group for installing and fixing short straight rods; brackets III1c, IV1d, and VI1e form a group for installing and fixing long straight rods; and brackets VII1f, VIII1g, and IX1h form a group for installing and fixing curved rods. Each bracket (I1a, II1b, III1c, VI1e, VII1f, and IX1h) has a mounting hole for a tethering ring 5 on its web surface, and the web surfaces of these brackets are connected to the frame to provide support for the rod and its overload.

[0028] The support rod 2 is divided into support rod I 2a and support rod II 2b. Support rod I 2a is an L-shaped profile used to connect the middle vertical rib of the support 1 to the long stringer. Support rod II 2b is a trapezoidal sheet metal bending piece used to connect the column 3 and the fuselage skin. The column 3 is used to connect the support 1, the frame and support rod II 2b, providing longitudinal support for the support 1. It also includes an anti-wear pad 4, which is pasted onto the upper surface of the curved vertical rib of the support 1 to prevent the rod and the support 1 from rubbing against each other and to increase the coefficient of friction between the rod and the support 1. The tethering ring 5 is used to fix the longitudinal binding rope. The auxiliary binding rope is used for the lateral and longitudinal binding of the support 1 and the rod, transferring the vertical and lateral loads of the rod to the support 1 and preventing the rod from sliding.

[0029] When installing the fixed pole, two people lift pole 4 onto bracket 1 and hold it until the binding is complete. Another person uses a binding rope and a hooked tethering rope to secure the pole and bracket 1 together. One end of the hooked tethering rope is fixed to the tethering ring 5 at both ends of the pole, and the other end is hooked to the pole end. Finally, the hooked tethering rope is secured to the pole with the binding rope. Figure 1 ,like Figure 2 ,like Figure 3 ,like Figure 4 ,like Figure 5 ,like Figure 6 ,like Figure 7 ,like Figure 8 ,like Figure 9 As shown.

[0030] During disassembly, two people should hold both ends of the pole with their hands to prevent the pole from sliding and injuring personnel, the machine structure, or onboard equipment after the binding ropes and hook-attached ropes are loosened. After all binding ropes and hook-attached ropes are removed, the pole should be safely moved outside the machine and all binding ropes and hook-attached ropes should be stored in the corresponding equipment box.
