Abstract
The utility model discloses a limiting belt mechanism for the 360-degree rotation of a forest fire prevention table. The limiting belt mechanism consists of a limiting rod and a limiting pull belt, wherein the limiting rod is connected to a rotatable azimuth axis through a bolt, the lower end of the limiting pull belt is wound on the bolt, the upper end of the limiting pull belt is compressed on a base of the azimuth axis through a limiting pressing plate, the other end of the limiting pull belt is compressed, and the limiting turn angle of the limiting pull belt is 360-400 degrees. The limiting belt mechanism can be used for well solving the problem that a certain slewing mechanism requires the limiting with the turn angle of 360-400 degrees, and as the limiting pull belt has certain elasticity, powerful hard impact caused by sudden stopping of a fast turning part can be better prevented so as to avoid the damage to an optical sensor or an electrical component caused by strong impact.
Description
Technical field
The utility model relates to the spacing and minimizing knocking gear of a kind of rotational angle, 360 ° of rotary stopper bands of particularly a kind of forest fire protection billiard table mechanism.The utility model can make the forest fire protection billiard table in 360 ° of scopes to corner spacing with alleviate bump.
Background technology
The azimuth axis system of forest fire protection billiard table is driven by the high power DC torque motor; Have a plurality of photoelectric sensors in the inside of its billiard table; Need tens of cables to pass the azimuth axis system; In order to prevent that cable from twining or twisting off, and satisfy the anglec of rotation simultaneously, need carry out spacing the rotational angle of orientation axle system greater than 360 °.Higher angular velocity of rotation and angular acceleration are arranged when billiard table rotates in addition, and optics or electric component for fear of strong bump damage transducer need the brake apparatus that a cover alleviates bump, and it is stopped the rotation rapidly.
Summary of the invention
The purpose of the utility model provides 360 ° of rotary stopper bands of a kind of forest fire protection billiard table mechanism, with the optics or the electric component of transducer in the azimuth axis system that avoids strong bump damage forest fire protection billiard table.
The utility model is made up of gag lever post and spacing drawstring; Wherein gag lever post is connected on the rotary azimuth axis with bolt; The lower end of spacing drawstring is on bolt, and the upper end of spacing drawstring is pressed on the azimuth axis base with spacing pressing plate and the other end of spacing drawstring is compressed.
The spacing angle of the utility model corner depends on the elasticity after spacing drawstring two ends are fixed, and spacing corner can be regulated between 360 °～400 °.
The course of work of the utility model is following:
Azimuth axis drives gag lever post and can in 360 ° scope, rotate freely, and moves in a circle around the azimuth axis axle center with azimuth axis, and spacing drawstring then is in stationary state.
If when azimuth axis drives gag lever post along clockwise direction continuously near spacing drawstring, the gag lever post cantilever will contact with spacing drawstring, and under the reaction force acts that spacing drawstring is given, finally stop operating fully.Can play effect spacing and the minimizing bump during the inhour motion equally.
The beneficial effect of the utility model:
The utility model can solve 360 °～400 ° spacing problems of some slew gear requirement corner well, and because spacing drawstring has certain elasticity, can prevent better that the powerful hard hit that fast rotation parts all standing brings from hitting; Avoided that strong bump damages optical pickocff or electric component.

Embodiment
See also illustrated in figures 1 and 2; The utility model is made up of gag lever post 1 and spacing drawstring 3; Wherein gag lever post 1 is connected on the rotary azimuth axis 6 with bolt; The lower end of spacing drawstring 3 is on bolt 2, and the upper end of spacing drawstring 3 is pressed on the azimuth axis base 5 with spacing pressing plate 4 and the other end of spacing drawstring 3 is compressed.
The spacing angle of the utility model corner depends on the elasticity after spacing drawstring 3 two ends are fixed, and spacing corner can be regulated between 360 °～400 °.
The shape of gag lever post 1 is as shown in Figure 3.
The shape of spacing drawstring 3 is as shown in Figure 4.
The shape of spacing pressing plate 4 is as shown in Figure 5.
The course of work of the utility model is following:
If when azimuth axis 6 drives gag lever posts 1 along clockwise direction continuously near spacing drawstring 3, gag lever post 1 cantilever will contact with spacing drawstring 3, and under the reaction force acts that spacing drawstring 3 is given, finally stop operating fully.Can play effect spacing and the minimizing bump during the inhour motion equally.
