Abstract
The utility model discloses an airplane service ground-well take-up pulley driving device, which comprises a driving motor, a driving gear that is connected with the driving motor and a friction pulley that is driven by the driving gear to be matched with the take-up pulley. When paying off, the take-up pulley is free from producing the inertia rotation, so that the cable is free from loosening on the take-up pulley; when taking up the cable, the cable is free from knotting; and moreover, when the take-up pulley is suddenly blocked to stop the rotation, the motor is free from being damaged.
Description
Technical field
The utility model relates to a kind of aircraft duties ground well that is used for airport hardstand, comprehensive maintenance hangar, relates in particular to a kind of aircraft duties ground well take-up pulley actuating device.
Background technology
Existing aircraft duties ground well generally is divided into manual ground well, S. A. ground well and full automaticity ground well.In the existing aircraft duties ground well, directly drive take-up pulley by drive motor in the take-up mechanism, during take-up, by the driven by motor take-up pulley, power lead directly is wound on the take-up pulley, unwrapping wire directly adopts manpower to pull out from take-up pulley power lead when using.Adopt this kind take-up mechanism mainly to have following problem: when one, unwrapping wire used, when the manpower backguy, take-up pulley inertia can occur and rotate, and made the cable on the take-up pulley loosening.Two, during take-up, electrical motor directly drives take-up pulley and reels, directly with cable winding on take-up pulley, cable tangled phenomenon on take-up pulley appears easily, cause and can not normally use.Three, when take-up pulley suddenly during stuck stopping operating, damage motor easily.
The utility model content
The purpose of this utility model is to overcome the problems referred to above that existing aircraft duties ground well exists when the take-up unwrapping wire, a kind of aircraft duties ground well take-up pulley actuating device is provided, the utility model is when unwrapping wire, making take-up pulley can not produce inertia rotates, cable can not become flexible on take-up pulley, during take-up, tangled phenomenon can not appear, and when the unexpected stuck Shi Buhui damage motor that stops operating of take-up pulley.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of aircraft duties ground well take-up pulley actuating device comprises drive motor, it is characterized in that: also comprise driving the friction wheel cooperate with take-up pulley with drive motor bonded assembly driven wheel with by driven wheel.
The utility model also comprises the friction force control apparatus, and described friction force control apparatus is a regulating spring, and regulating spring one end is connected with friction wheel, and the other end is connected with take-up pulley.
In the described driven wheel is the click structure.
Advantage of the present utility model is:
One, the utility model comprises drive motor, drive the friction wheel that cooperates with take-up pulley with drive motor bonded assembly driven wheel with by driven wheel, in the driven wheel is the click structure, during take-up, drive motor just changes, drive the take-up pulley take-up, during unwrapping wire, the take-up pulley counter-rotating drives friction wheel and driven wheel rotation under the manpower backguy effect, because the drive motor rotating speed is certain, if speed is greater than the situation of drive motor rotating speed, because the click effect in the driven wheel, gear does not rotate, can not produce inertia and rotate, cable can not become flexible on take-up pulley.
Two, in the utility model, during take-up, cable tension makes take-up pulley different with the friction force between the friction wheel not simultaneously, and the take-up pulley rotating speed is changed, and tangled phenomenon can not occur.
Three, drive take-up pulley by friction wheel friction in the utility model and rotate, during take-up, with take-up pulley is stuck when stopping operating, take-up pulley and friction wheel skid, and have avoided the damage drive motor when suddenly.
Four, the utility model also comprises the friction force control apparatus, the friction force control apparatus is a regulating spring, and regulating spring one end is connected with friction wheel, and the other end is connected with take-up pulley, friction force size between scalable take-up pulley and the friction wheel, thereby control take-up pulley rotating speed.
Description of drawings
Fig. 1 is the main TV structure scheme drawing that the utility model cooperates with take-up pulley
Fig. 2 is Fig. 1 left side TV structure scheme drawing
Be labeled as among the figure: 1, take-up pulley, 2, drive motor, 3, driven wheel, 4, friction wheel, 5, the take-up groove, 6, regulating spring.
The specific embodiment
A kind of aircraft duties ground well take-up pulley actuating device comprises drive motor 2, also comprises with drive motor 2 bonded assembly driven wheels 3 with by driven wheel 3 driving the friction wheel 4 that cooperates with take-up pulley 1.
The utility model also comprises the friction force control apparatus, and described friction force control apparatus is a regulating spring 6, and regulating spring 6 one ends are connected with friction wheel 4, and the other end is connected with take-up pulley 1.
Be provided with the take-up groove 5 that cooperates with cable on take-up pulley 1, take-up groove 5 is shape distribution in the shape of a spiral on take-up pulley 1, is provided with the carbon brush slip-ring with cable connection in the take-up pulley 1.Be positioned at take-up groove 5 outsides on the take-up pulley 1 and be provided with a bumping post, the bumping post two ends are connected with take-up pulley 1 two ends respectively.In the driven wheel 3 is the click structure.
The utility model comprises drive motor 2, drive the friction wheel 4 that cooperates with take-up pulley 1 with drive motor 2 bonded assembly driven wheels 3 with by driven wheel 3, in the driven wheel 3 is the click structure, during take-up, drive motor 2 is just changeing, drive take-up pulley 1 take-up, during unwrapping wire, take-up pulley 1 counter-rotating drives friction wheel 4 and driven wheel 3 rotations under the manpower backguy effect, because drive motor 2 rotating speeds are certain, if speed is greater than the situation of drive motor 2 rotating speeds, because the click effect in the driven wheel 3, driven wheel 3 does not rotate, can not produce inertia and rotate, cable can not become flexible on take-up pulley 1.During take-up, cable tension makes take-up pulley 1 different with the friction force between the friction wheel 4 not simultaneously, and take-up pulley 1 rotating speed is changed, and tangled phenomenon can not occur.Drive take-up pulley 1 by friction wheel 4 frictions and rotate, during take-up, when suddenly with take-up pulley 1 stuck stopping operating, take-up pulley 1 skids with friction wheel 4, has avoided damage drive motor 2.The friction force control apparatus is a regulating spring 6, and regulating spring 6 one ends are connected with friction wheel 4, and the other end is connected with take-up pulley 1, the friction force size between scalable take-up pulley 1 and the friction wheel 4, thereby control take-up pulley 1 rotating speed.
Obviously; those of ordinary skill in the art is according to technological know-how of being grasped and customary means; according to above said content, can also make the various ways that does not break away from the utility model basic fundamental thought, these pro forma conversion are all within protection domain of the present utility model.
