Problems solved by technology
[0003] Hoisting and truck installation are two commonly used assembly methods. The hoisting method has a relatively simple structure, low material cost, and short manufacturing period. The device cannot send the assembled parts under the large-sized parts for attitude adjustment assembly
For example, when assembling the pod pylon under the wing of a certain type of aircraft, due to the cover of the wing, the ordinary hoisting device cannot send the engine pylon to the bottom of the wing for assembly. In addition, because there is a fixed platform under the wing, there are multiple The step difference and the rigidity of the platform are poor, and the installation vehicle cannot be placed or walked on the platform, so the installation vehicle cannot be used for installation, even if there is no fixed platform under the wing, because the lower surface of the wing is far from the ground, such as the lower surface of the wing of a certain type of aircraft If the distance from the ground is greater than 5m, if the installation vehicle is used for installation, the lifting height of the installation vehicle will be high, which will increase the manufacturing cost of the installation vehicle sharply, and due to the high lifting height, the installation vehicle has to increase the chassis to ensure stability. The installation vehicle occupies a large area of the factory building, so the economical efficiency of installation with the installation vehicle is poor

Embodiment Construction
[0021] Referring to the accompanying drawings, the offset type aerial attitude adjustment installation device of the present application, the installation device is as figure 1 As shown, it contains a hanging beam 1, a lifting assembly 2, an attitude adjustment bracket 3 and a counterweight assembly 4. The suspension beam 1 is a rectangular frame, and one end of the rectangular frame is provided with an installation position of the attitude adjustment bracket 3. The frame beam structure is provided with the installation frame beam structure of the breeding assembly at the other end of the rectangular frame, and four attitude-adjusting lifting bolts 6 are distributed in the middle of the rectangular frame. The attitude-adjusting bracket 3 is fixed on one end of the suspension beam 1 through four lifting feet 13, and the counterweight assembly 4 is connected to the other end of the suspension beam 1 through a sliding pair 21. The position of the center of gravity of the counterwe...

The invention relates to an offset type aerial posture adjustment mounting device and a using method. The mounting device comprises a hanging cross beam, a hoisting assembly, a posture adjustment bracket and a counterweight assembly. The hanging cross beam is a rectangular frame, the posture adjustment bracket is located at one end of the hanging cross beam, the counterweight assembly is located at the other end of the hanging cross beam, the gravity center position of the counterweight assembly is adjustable relative to the hanging cross beam, and the hoisting assembly is connected to the upper side of the middle of the hanging cross beam.
Description
technical field [0001] The present application relates to the technical field of aircraft assembly tooling, in particular to an offset aerial attitude adjustment installation device and its usage method. Background technique [0002] In the process of aircraft assembly, component assembly is an indispensable link. When the assembled component is large, a special device is required to transport the assembled component to the assembly position. At the same time, the special device adjusts the attitude of the assembled component in all directions, and finally Docking with another component to complete the assembly. [0003] Hoisting and truck installation are two commonly used assembly methods. The hoisting method has a relatively simple structure, low material cost, and short manufacturing period. The device cannot send the parts to be assembled under the large-size parts for attitude adjustment assembly. For example, when assembling the pod pylon under the wing of a certain...
