Wire and cable dispensing container and systems

A container for the dispensing of wire or cable has an external carton which receives a reel of cable as supported by two caddies. Each caddy has an inwardly extending substantially cylindrical bushing which is received in a central hole of a respective cable reel flange. The cylindrical bushings are disposed on an axis which is a first distance from the upper surface of the bottom panel of the carton. The largest radius of each reel flange is preselected to be smaller than this such that the reel may freely rotate inside of the carton on the bushings. Cable is pulled through a slot in the carton's front panel. Preferably, left and right panels of the carton each have an arbor hole formed therein which receives an axial rod, the rod also extending through the reel and caddies. The axial rod may be used to join two or more containers together and may further serve as a support for attachment of a wheel truck on one end of the joined-together containers and a handle at its other end. An alternative, four-wheeled cart has multiple axial rods. An alternative hand truck likewise receives multiple axial rods through respective container passageways. In one embodiment, cable may be pulled through one or more pass-through slots formed in the tops and bottoms of stacked containers, such that cable from multiple containers is drawn through one slot on the top of the stack.

Rotating ejection device for small and medium unmanned aerial vehicle

The invention relates to a rotating ejection device for small and medium unmanned aerial vehicles, which is characterized in that two motors are fixedly arranged on a stand column of an ejection frame; gears of the two motors are respectively installed on output shafts of the two motors; a gear disc is sheathed on the gears of the two motors, and the inner teeth of the gear disc are engaged with the gears of the two motors; a counterweight bar and a linkage crossbar are arranged above the gear disc, are symmetrically clamped and sheathed on a supporting bar and are tightly fixed through two fastening pieces; a counterweight is installed on the counterweight bar and can slide along the counterweight bar; one end of a movable swing arm is hinged with the end of the linkage crossbar through a connecting piece; and the other end of the movable swing arm is hinged with an unmanned aerial vehicle gripping and releasing mortise lock. By controlling the rotating speed of the motors of the rotating ejection device to control the ejection speed of the small and medium unmanned aerial vehicles to be within 0 to 50m/s, the overload of the small and medium unmanned aerial vehicles during takeoff can be effectively reduced, and the service lives of the unmanned aerial vehicles can be prolonged. The rotating ejection device for the small and medium unmanned aerial vehicles has the characteristics that the production cost and the using cost are low, the occupied area is small, the device is convenient to operate and can be mounted on vehicles and ships for use.

Hoisting system of large-sized extensible antenna

InactiveCN102050409ANot limited by test spaceConvenient multi-point uninstallationLifting devicesEngineeringZero gravity
The invention discloses a hoisting system for a large-sized extensible antenna, and in particular relates to a ground testing system for the extensible antenna. The hoisting system provided by the invention mainly solves the problem that the existing testing system can not simulate the space zero gravity extension for the extensible antenna in the ground stimulation. The system provided by the invention comprises a lifting rod (1), a positioning cable (2), a supporting cable (3), a hoisting ring (4), a pulling cable (5) and a counter weight (6), wherein the supporting cable (3) is an equilateral polygon parallel to the opening surface of the extensible antenna (7); the hoisting ring (4) is arranged in each cross position of the radially arranged positioning cable (2) and supporting cable (3); the pulling cable (5) passes through the hoisting ring (4) and is respectively connected with the counter weight (6) and the extensible antenna (7); and one end of the positioning cable (2) is connected with the upper end of the lifting rod (1), and the other end of the positioning cable and the other end of the lifting rod are fixed with the ground so as to form a circular conical surface extensible supporting structure with the lifting rod (1) as the center. The hoisting system provided by the invention is convenient in gravity unloading, is not limited by the testing space and can be used for the ground extension test of the extensible antenna.
