Description
Technical field
The utility model belongs to safety net technical field more particularly to a kind of airport worm and gear activity safety net.
Background technology
For ease of taking off, aloft platform, such as building roofdeck and ship's deck is arranged in many helistops,
To prevent personnel's accidental falling on helistop, the surrounding of helistop is provided with fixed security protection
Device, these safety nets influence to limit to a certain extent the space on aircraft machine level ground, serious to influence taking off and dropping for aircraft
It falls, therefore how to facilitate timely either on or off safety net as the key of problem.
Therefore, a kind of airport worm and gear activity safety net is invented to be very necessary.
Utility model content
In view of the above technical problems, the utility model provides a kind of airport worm and gear activity safety net.
A kind of airport worm and gear activity safety net, which is characterized in that the airport worm and gear activity safety net includes net
Frame, dictyosome, universal wheel, shaft, worm gear, worm screw, motor, installation set, boss and holder；Among rack one is connected in square hole
Dictyosome, the rack lower end are equipped with several universal wheels, and described rack one end is connected with a shaft, the shaft upper and lower ends point
It does not stretch into inside installation set, the expanded bolt of installation set is fixed on wall, and a holder, the holder are equipped on wall
On a worm screw is installed, the worm shaft end connects motor output shaft, the worm screw with outside the worm gear being fixed in the shaft
Engagement, the upper and lower end parts of the shaft have been respectively and fixedly connected with a discoidal boss.
Preferably, the dictyosome is formed by polyvinyl and nylon shuffling.
Preferably, the boss diameter is more than the installation set aperture.
Preferably, the holder is embedded in inside wall.
Preferably, the shaft can rotate 0-180 ° along center axis.
Compared with prior art, the utility model has the advantages that：The utility model is simple in structure, using worm gear
Worm structure drive shaft drives rack to rotate 180 degree, has the characteristics that consolidating for dictyosome is realized in self-locking using worm gear structure
It is fixed, it is needed under the driving of worm screw according to using, dictyosome can be opened freely, be closed, laborsaving convenience.
Description of the drawings
Fig. 1 is the utility model of the whole structure diagram.
In figure：
1- racks, 2- dictyosomes, 3- universal wheels, 4- shafts, 5- worm gears, 6- worm screws, 7- motors, 8- installation sets, 9- boss,
10- holders.
Specific implementation mode
The utility model is described further below in conjunction with attached drawing：
Embodiment：
As shown in Fig. 1, the utility model provides a kind of airport worm and gear activity safety net, which is characterized in that the machine
Worm and gear activity safety net include rack 1, dictyosome 2, universal wheel 3, shaft 4, worm gear 5, worm screw 6, motor 7, installation set 8,
Boss 9 and holder 10；One dictyosome 2 is connected in 1 intermediate square hole of rack, 1 lower end of rack is equipped with several universal wheels 3, rack 1
One end is connected with a shaft 4, and 4 upper and lower ends of shaft are respectively protruding into inside installation set 8, and 8 expanded bolt of installation set is fixed in wall
One holder 10 is installed on body, on wall, a worm screw 6 is installed on holder 10,6 shaft end of worm screw connects 7 output shaft of motor, worm screw
6 have been respectively and fixedly connected with a discoidal boss 9, dictyosome 2 with 5 external toothing of worm gear that is fixed in shaft 4, the upper and lower end parts of shaft 4
It is formed by polyvinyl and nylon shuffling, 9 diameter of boss is more than 8 aperture of installation set, and holder 10 is embedded in inside wall, and shaft 4 can edge
Center axis rotates 0-180 °.
Operation principle
When utility model works, drive worm screw 6 to rotate using the rotation of 7 output shaft of motor, the worm screw 6 on holder 10 with
5 external toothing of worm gear in shaft 4 realizes 0-180 ° of rotation of rack 1, worm gear snail to drive worm gear 5 that shaft 4 is driven to rotate
Rod structure has self-locking function, therefore when promotion rack 1, rack 1 cannot drive shaft 4 to rotate, and 9 diameter of boss is more than installation set
8 apertures, shaft 4 are sleeved on inside 8 hole of installation set, and it is the positioning of shaft 4 and supporting role that boss 9, which has, and the present apparatus is simple in structure,
Reliable operation, unlatching closure is laborsaving, can freely control the closure of safety net as needed.
Using technical solution described in the utility model or those skilled in the art in technical solutions of the utility model
Under inspiration, similar technical solution is designed, and reaches above-mentioned technique effect, is the protection model for falling into the utility model
It encloses.
