Abstract
Provided is a low-speed wind tunnel expansion section tensioning mechanism which comprises a pull hook, a movable section, a movable section support, an expansion section fixation section, a fixation section support, a shaft head, a friction disc coupler, a lifter and a motor. The movable section is fixedly connected to the lower end of the movable section support; the expansion section fixation section is fixedly connected to the lower end of the fixation section support; the pull hook is connected with the lifter through the shaft head; and the lifer is connected with the motor through the friction disc coupler. When the tensioning mechanism is used, after the movable section of an expansion section is moved in place, the motor is started, and the motor drives the lifter to be in telescoping movement through the friction disc coupler; the lifter drives the pull hook to move horizontally through the shaft head; and the pull hook, under the effect of gravity thereof, rotates around a pin shaft until contacting the movable section support, and finally, butt joint and tensioning of the movable section and the expansion section fixation section are realized. The low-speed wind tunnel expansion section tensioning mechanism can well realize butt joint and tensioning of the movable section and the expansion section fixation section; movement of the movable section can be realized through an air-floating transport system during opening; and wind tunnel test efficiency is improved.
Description
Technical field
The present invention relates to low-speed wind tunnel field, be specifically related to a kind of low-speed wind tunnel diffuser tensioning mechanism.
Background technology
Along with the development of science and technology, cradle---the wind-tunnel that aerospace flight vehicle is born, has had application space more and more widely.Not only aircraft will " be dried ", nowadays automobile, building, bridge, and even sportsman also will test in wind-tunnel, and wind-tunnel technique is extended to all trades and professions from aerospace field.
For adapting to development and the development of aerospace flight vehicle, countries in the world have built the wind-tunnel of many various sizes and type in succession.Construction of wind tunnel is designed to cases of otherwise standard design, and different wind-tunnel has different structural shapes.Along with the development of computer technology and software engineering, modern structure designing technique continues to bring out, and construction of wind tunnel design must introduce a new concept, new thought, makes its structural design more reasonable.
Summary of the invention
The object of the present invention is to provide a kind of low-speed wind tunnel diffuser tensioning mechanism, for docking tension movable part section and fixed part section.
The technology used in the present invention is as follows:
A kind of low-speed wind tunnel diffuser tensioning mechanism, comprises drag hook, movable sections, movable sections bearing, diffuser canned paragraph, canned paragraph bearing, spindle nose, Friction disc coupling, lifter and motor; Movable sections is fixedly connected on movable sections bearing lower end, and diffuser canned paragraph is fixedly connected on canned paragraph bearing lower end, and drag hook is connected with lifter by spindle nose, and lifter is connected with motor by Friction disc coupling; During use, after the movable sections of diffuser moves into place, starter motor, motor drives lifter to do stretching motion by Friction disc coupling, lifter drives drag hook to move horizontally by spindle nose, drag hook rotates until contact with movable sections bearing around bearing pin under gravity, finally realizes movable sections and strains with docking of diffuser canned paragraph.
The features and advantages of the invention:
The invention provides a kind of low-speed wind tunnel diffuser tensioning mechanism, can open fast or closed drag hook, movable part section can be realized during closedown well strain with docking between canned paragraph, realize the movement of movable part section by air supporting transportation system when opening, use convenient and simple for operation, there is the advantage improving wind tunnel test efficiency, economize energy consumption.
Accompanying drawing explanation
Fig. 1 is front view under tensioning mechanism open mode.
Fig. 2 is vertical view under tensioning mechanism closure state.
Embodiment
Further illustrate according to Figure of description citing below:
As shown in accompanying drawing 1-Fig. 2, a kind of low-speed wind tunnel diffuser tensioning mechanism, comprises drag hook 1, movable sections 2, movable sections bearing 3, diffuser canned paragraph 4, canned paragraph bearing 5, spindle nose 6, Friction disc coupling 7, lifter 8 and motor 9; Movable sections 2 is fixedly connected on movable sections bearing 3 lower end, and diffuser canned paragraph 4 is fixedly connected on canned paragraph bearing 5 lower end, and drag hook 1 is connected with lifter 8 by spindle nose 6, and lifter 8 is connected with motor 9 by Friction disc coupling 7; During use, after the movable sections 2 of diffuser moves into place, starter motor 9, motor 9 drives lifter 8 to do stretching motion by Friction disc coupling 7, lifter 8 drives drag hook 1 to move horizontally by spindle nose 6, drag hook 1 rotates until contact with movable sections bearing 3 around bearing pin under gravity, finally realizes movable sections 2 and strains with docking of diffuser canned paragraph 4.
