Description

Technical Field

[0001] The present application relates to the field of bomb hanging vehicle brackets, and in particular to an adjustable bomb hanging vehicle bracket. Background Art

[0002] The missile carrier bracket is a mechanism for supporting missiles, and its height and operating space are key factors in designing the missile carrier. In the past, the missile carrier bracket was a fixed supporting mechanism, and the height of the traditional missile carrier bracket could not be adjusted. When there was insufficient space under the wing, the missile carrier could not be hung. At this time, if the chassis height of the missile carrier was lowered, major changes would be required, which was time-consuming, labor-intensive, costly, and difficult to modify.

[0003] Chinese patent CN105292490A discloses a height-adjustable bomb-hanging vehicle bracket, which includes a bottom plate, a lining plate, an arc plate and a felt. The middle of the bottom plate is fixed on the bomb-hanging vehicle support seat, and lining plates are installed at the front and rear positions of both ends of the bottom plate. The lining plate and the bottom plate are connected by an axis, and an arc surface is formed on the top of the lining plate. An arc plate is installed on the top of the lining plate, and the surface of the arc plate is provided with felt. The lining plate and the bottom plate are movably connected by an axis, and the modification is simple and the operation is convenient. There is no need to change other structures of the bomb-hanging vehicle. After the bomb is hung, the quick-release stop pins on both sides are pulled out, and the lining plate and the arc plate are laid down together, which reduces the height of the bomb-hanging vehicle bracket and increases the operating space.

[0004] The existing patent can design an adjustable height bomb carriage bracket, which can lower the height of the bomb carriage to adapt to the height of the wing. However, when adjusting the height of the bracket, the position of the shell placed on the bracket is prone to deviation, and the lifting ear on the top of the shell is not easy to connect with the hook on the aircraft. It is necessary to re-take the shell and reload it or the operator needs to adjust it manually, which is time-consuming and laborious, and seriously affects the efficiency of bomb hanging.

The base 1 in the bomb-hanging vehicle bracket 2 is mounted with a bottom plate 11, and the bracket 2 symmetrically mounted on the bottom plate 11 is used to support the shells to be loaded. The bracket 2 uses several groups of support wheels 23 to support the shells, and the bracket 2 uses an integrally formed lining plate 21 and a connecting plate 212 as the main body to install the support wheel 23, which has good strength and support performance. A reduction motor 211 is installed in the lining plate 21, and the gear on the output shaft of the reduction motor 211 drives the gear at the end of the support wheel 23 to rotate, thereby driving the support wheel 23 to rotate.

In addition, the bracket 2 is rotatably installed on the bottom plate 11, and the bottom of the other end of the lining plate 21 on the bracket 2 drives the bracket 2 to rotate on the bottom plate 11 through the first hydraulic lifting mechanism 112, and the outer diameter of the shells placed on the bracket 2 is adjusted, so as to meet the placement requirements of shells with different outer diameters.
