Abstract
The utility model belongs to the technology of load loading and transmitting, and relates to a bi-direction transmitted load loading device of an arc-shaped structure. The bi-direction transmitted load loading device of the arc-shaped structure comprises a woven belt, a wood block, a clamp and an aluminum pipe. The woven belt is filled with the wood block, the clamp is fixed to the upper surface of the wood block, the clamp is provided with a clamp loading hole and a clamp preformed hole, and the aluminum pipe is embedded into the clamp loading hole. The bi-direction transmitted load loading device can be attached to the surface of the arc-shaped structure, the requirement for multiple loading nodes can be met, the loading response is fast, the loading space and the number of loading devices needed in an arc-shaped structure test are reduced, the test preparing period is shortened, and the bi-direction transmitted load loading device can be applied to transmitting load of an undercarriage cabin door, the front edges of wings, air inlet channels, back strips of a machine body and other arc-shaped structure portions.
Description
Technical field
The utility model belongs to load and loads Transfer Technology, relates to a kind of arcuate structure bi-directional load charger.
Background technology
In aircaft configuration static(al), fatigue test, at arc parts such as undercarriage doors, be subject to the impact of the reasons such as space, time, need to use a set of loading system to apply tension compression bidirectional load.Yet in aircaft configuration strength test in the past, particularity because of these portion structures, conventional bi-directional load charger all cannot meet the demands, can only use the device of unidirectional delivery load, need larger loading space and more loading facilities, and press to transmitted load force-input device less loading node can only be set, cause body structure surface load applying concentrations, load simulated distortion, when these equipment are installed, also extend the preparatory period of test, promoted experimentation cost.
In order to reduce arcuate structure, test required loading space and loading facilities, shorten the test preparatory period, need a kind of device that can transmit bidirectional load on arcuate structure.
Summary of the invention
The purpose of this utility model: a kind of arcuate structure bi-directional load charger is provided, has solved the problem of aircraft arcuate structure biaxial loadings.
The technical solution of the utility model: a kind of arcuate structure bi-directional load charger, it comprises canvas belt, wooden unit, fixture and aluminum pipe, wherein, wooden unit is filled in canvas belt, described fixture is fixed on wooden unit upper surface, on fixture, be provided with fixture and load hole and fixture preformed hole, aluminum pipe is embedded in fixture and loads in hole.
Described wooden unit lower surface adopt that numerical control machining becomes that single curved surface, double curved surface, cylindrical etc. and arcuate structure surface match shape.
Canvas belt loading end is set on described canvas belt.
It is a pair of that described fixture loads hole, and fixture preformed hole is arranged on two fixtures and loads between hole.
Beneficial effect of the present invention: the invention solves and do not have force-input device can transmit on arcuate structure surface the problem of bidirectional load in the past, after its good effect is that a set of loading facilities is attached thereto, by being arranged on the joint on described fixture preformed hole (7), special lever system can will be distributed in arcuate structure surface, the loading node that this device is installed connects into a concentrated loading point, thereby can be in arcuate structure surface bi-directional load, use amount and the amount of changing the outfit of loading facilities have been reduced, shortened the test preparatory period, and can be widely used.

The specific embodiment
Below by the specific embodiment, the present invention is described in further detail:
Please refer to Fig. 1-Fig. 6, the utility model globoidal structure bi-directional load charger comprises canvas belt 1, wooden unit 2, fixture 3 and aluminum pipe 4.Wherein, wooden unit 2 is filled in 1 li of canvas belt, and described fixture 3 is placed on wooden unit 2 upper surfaces, is provided with fixture and loads hole 6 and fixture preformed hole 7 on fixture 3, and aluminum pipe 4 is embedded in fixture and loads in hole 6 and canvas belt loading end 5, and whole device is connected as a single entity.
In present embodiment, adopt wooden unit as packing material, be used for transmitting ballast, its low price, surface can adopt that numerical control machining one-tenth and single curved surface, double curved surface, cylindrical etc. and arcuate structure surface match shape, and there is good rigidity, can not produce crush injury to body structure surface.If adopt rubber-like or polyurethane material, although be better than wooden unit aspect elasticity, these materials cannot carry out numerical control machining, can not meet the requirement of transmitting ballast timer and the laminating of globoidal structure surface.Because canvas belt 1, wooden unit 2, fixture 3 are not one, if packing material distortion is excessive during ballast, canvas belt 1 excessively loosens, pressure-La switching process the time longer, reduced loading efficiency, wooden unit can not produce this problem.
Fixture 3 can load the position in hole 6 by adjustment, make canvas belt loading end 5 in tight state, draws while carrying and can respond rapidly, and guarantee load direction of transfer in transmission.
Fixture 3 can be adjusted profile according to arcuate structure shape, avoids interference structure distortion, reduces clamp structure weight.
Preformed hole on fixture 3 is installed special joint, by loading facilities, can connect a plurality of distributed load nodes, load being uniformly distributed at whole globoidal structure while guaranteeing to load.
Core content of the present utility model is by adopting rational structure design, formed a kind of suitable apparatus structure form, can be according to the size of loading demand and arcuate structure, adjust the size of canvas belt 1, wooden unit 2, fixture 3, aluminum pipe 4, meet the arcuate structure surface of different size, different loads size, the demand that different loads distributes.In theory, this device can transmit undercarriage door, the leading edge of a wing, the load at the arcuate structure positions such as inlet channel.
