Description

Technical Field

[0001] The utility model belongs to the field of aircraft functional tests and detections, and relates to a fixing device for a frame-type hanger. Background Technique

[0002] The frame-type hanger is a listed product of the aircraft suspension and delivery device, mainly used for hanging, carrying, and delivering suspended objects. Its main function is to lock and release the suspended objects and transmit the current mounting state to the main control system in real time. Since the mechanical cooperation between the frame-type hanger and its matching bomb hook is affected by the later installation quality, the mechanical cooperation between the frame-type hanger and the bomb hook is an important detection item for the frame-type hanger. The bomb hook of the frame-type hanger provides information about the suspended object and suspension during suspension and transportation, and when the computer issues a release command, it releases layer by layer (from bottom to top). After successful release, the bomb hook will naturally droop downward under the influence of gravity. If the bomb hook cannot be naturally retracted or is not fully retracted, it will affect the release of the upper suspended objects and cause some irreversible damage.

[0003] At present, after the frame-type hanger and the bomb hook arrive at the factory, they cannot be assembled and tested in the laboratory, which results in the inability to install and test the mechanical cooperation between the frame-type hanger and the bomb hook in the laboratory. It is extremely inconvenient during the entire production and testing process, resulting in the inability to carry out this work normally. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described below in conjunction with embodiments. The following only describes some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] A frame-type mounting bracket fixing device is provided, including a base and a mounting backboard.

[0021] The base serves as the base support for the entire fixing device, provides an installation support for the installation backplane, and there is a stop block directly in front of the base, which provides protection and installation fixation when installing the frame hanger; there is a level above the base to ensure the level of the base.

[0022] The installation backplane provides an installation position and installation fixation points for fixedly installing the frame hanger. There are 6 installation fixing screws on the installation backplane, and the screws can all be adjusted horizontally, providing a certain range of free installation adjustment when installing the frame hanger; a support rod is provided on the side wall of the backplane, and a plumb bob is connected to the support rod to ensure checking the vertical state between the backplane and the base.

[0023] A detailed description of a frame hanger fixing device of the present utility model is as follows:

[0024] As Figure 2 shown, it is the actual state when the frame hanger loads the suspended object, and it is perpendicular to the horizontal plane and downward.

[0025] As Figure 1 shown, it is a schematic diagram after the frame hanger fixing device is fixedly connected to the frame hanger. In this state, it reaches the vertical horizontal plane downward of the actual state, and the base of the fixing device is supported at four corners. When supporting the weight of the entire fixing device and the frame hanger, it has a certain degree of mobility, and even the weight of the additional suspended object can be fully supported. Its fixing method is to install and fix by corresponding 6 fixing screws (which can be freely adjusted within a certain range horizontally and are convenient for installation) on the backplane of the fixing device with 6 fixing holes on the frame hanger. The installation and disassembly are convenient and simple, and the operability is high.

[0026] During installation, place the frame hanger vertically on the fixing device, keep the back of the frame hanger close to the installation backplane, and make the 6 installation fixing holes correspond one by one. After installation, check whether the lower end face of the frame hanger is close to the base and the base stop block. If adjustment is needed, adjust the 6 installation screws on the backplane to make the frame hanger vertical to the horizontal plane after installation.

[0027] After installation, suspended objects can be loaded on hooks 4, 5, and 6. The electrical interface of the frame hanger is connected to the computer, and the hook state can be displayed on the computer. The test can start with a simulated drop. When the first suspended object is dropped, check whether the bomb hook retracts and does not affect the dropping of the second suspended object. Then the frame hanger can drop the suspended objects in sequence. The dropping order is that hook 6 drops first, followed by hook 5, and finally hook 4.
