Problems solved by technology
[0002] During aircraft assembly or maintenance work, it is necessary to use spreader equipment to lift parts to or from the installation position, but traditional spreader equipment often requires lifting points on the aircraft, which adds an additional burden to the structural design of the aircraft
In addition, due to the structural differences of the external frames, the installation of the hoisting system between the two sides of the outer frame often faces defects such as insufficient structural strength of the hoisting frame, or insufficient mutual fixation between the cross bar of the hoisting frame and the guide rail.

Embodiment Construction
[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples. For the convenience of the discussion, "up", "down", "left", and "right" are used to indicate the directions in each schematic diagram, which is conducive to the development of the discussion.
[0031] combine Figure 1 to Figure 7 , understand the preferred hoisting system for aircraft component assembly of the present invention. Such as figure 1 , 4A , 4B, and 6, the hoisting frame of the present invention includes: the first crossbar 1 of the hoisting frame, the second crossbar 2 of the hoisting frame, and the guide rail 3. Both the first crossbar 1 of the hoisting frame and the second crossbar 2 of the hoisting frame are telescopically adjustable.
[0032] Such as figure 1 and Figure 4A , 4B , 4C, the first crossbar 1 of the suspension frame includes the first section 11 of the first crossbar and the second section 12 of the fi...

The invention provides a lifting frame for assembling of aircraft parts. The lifting frame comprises a first lifting frame cross bar, a second lifting frame cross bar and a guide rail, wherein one end of the guide rail is fixed to the first lifting frame cross bar, and the other end of the guide rail is fixed to the second lifting frame cross bar; an opening of the guide rail is downward; a rolling wheel is arranged in the guide rail; a lifting lug is arranged on the lower portion of the rolling wheel; at least one end of the guide rail is curved; the curved part is tangent to the first lifting frame cross bar and / or the second lifting frame cross bar. The lifting frame has the following characteristics that as the curved end of the guide rail is tangent to the corresponding lifting frame cross bar, this portion of the guide rail and the lifting frame cross bar have the same direction and can be both fixed firmly, and the bearing capacity of the lifting frame is high; the lifting frame can conduct lifting without a lifting point. The invention further provides a lifting system corresponding to the lifting frame.
Description
technical field [0001] The invention relates to a hoisting frame and a hoisting system used for assembling aircraft parts. Background technique [0002] During aircraft assembly or maintenance work, it is necessary to use spreader equipment to lift parts to or from the installation position, but traditional spreader equipment often requires lifting points on the aircraft, which adds an additional burden to the structural design of the aircraft. In addition, due to the structural differences of the external frames, the arrangement of the hoisting system between the two external frames often faces defects such as insufficient structural strength of the hoisting frame, or insufficient mutual fixation between the crossbar of the hoisting frame and the guide rail. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a kind of hanger that is used for the assembly of aircraft parts, comprising: [0004] The f...
