Specific embodiment
The present invention as shown in figs 1-9, including cabinet 1, main shaft 2, wirerope 3, reset assembly and brake assemblies, the cabinet
1 in rope hole is offered on hollow shape and one side surface, the main shaft 2 wears the cabinet 1 and, institute hinged with cabinet 1
It states one end of wirerope 3 and main shaft 2 is fixedly linked and is arranged with several circles outside main shaft 2, the other end of the wirerope 3 is stretched
Out to outside cabinet 1；
The reset assembly 4 is connected between main shaft 2 and cabinet 1 and for so that main shaft 2 keeps the movement to original state to become
Gesture；
The brake assemblies 5 include fixing seat 51, flywheel 52, several interior ratchets 53, at least one fly pawl 54 and at least tension spring 55,
The fixing seat 51 is fixedly connected in cabinet 1 and the socket main shaft 2, and the fixing seat 51 is towards on the end face in cabinet 1
Offer circular groove, the circular groove and main shaft 2 is concentric and empty set described in main shaft 2, several interior ratchets 53 are uniformly distributed
It is fixedly linked on the side wall of circular groove and with fixing seat 51；It is interior and same with main shaft 2 that the flywheel 52 is set to circular groove
Step rotates, and offers loose slot 521 on the side wall of the flywheel 52, the root of the winged pawl 54 is articulated in loose slot 521, institute
The both ends for stating tension spring 55 are respectively fixedly connected with middle part and the flywheel 52 of winged pawl 54, so that flying pawl 54 retains towards the rotation of 52 center of flywheel
The movement tendency turned；
The equipment fixed with ground such as the cabinet 1 and electric pole 33(or steel tower) it is connected, the wirerope 3 extend out to cabinet 1
Outer one end and cable 31 or pendant, which stick together, 32 to be connected.
The present invention in actual use, can as shown in figure 9, can first complete the connection that sticks together with cable of pendant (can be between
Pulley blocks are set)；Cabinet is connected on electric pole again (can choose one-to-one with the two according to the quantity that cable, pendant stick together
The safety of quantity)；Finally, pull out wirerope from outside rope hole phase, and complete wirerope and all pendants stick together, all cables
It is fixedly connected.So that this case when installing safety without holding cable simultaneously, hanging pendant and stick together, extremely convenient and labour
Intensity is low, security risk is small, has good delicate structure, stability on the whole, good braking effect, installs extremely convenient and nothing
The advantages that false triggering problem.
From the principle, when cable, pendant stick together when not disconnecting, as shown in figure 3, flywheel can be rotated freely, from
And safety is easily installed, simultaneously because the pulling force of tension spring exists, but also the problem of this case errorless triggering；
Once and cable, pendant stick together between connection disconnect, then main shaft and flywheel will be opened under the influence of cable or pendant stick together
Beginning high speed rotation is directed away from flywheel center so that all winged pawls be made to overcome the active force of tension spring under the influence of centrifugal force
Direction whipping, and be finally caught in the gap of adjacent interior ratchet, as shown in figure 5, carrying out effective rotation stop to main shaft.In this way,
On the one hand, that is, avoid that cable occurs by free-falling the problem of breaking, play the effective protection to cable；Separately
On the one hand, it also can effectively hold pendant to stick together, avoid pendant and stick together the problem of smashing itself and underlying device because of free-falling；It plays
The bidirectional protective to stick together to cable and pendant.
The reset assembly 4 includes reset seat 41 and plane scroll spring 42, and the reset seat 41 is fixedly connected on cabinet 1
The interior and socket main shaft 2 is also provided with the accommodation groove for accommodating plane scroll spring 42 in the reset seat 41, described
Plane scroll spring 42 is set in accommodation groove and is arranged the main shaft 2, and one end of the plane scroll spring 42 and main shaft 2 are solid
It connects calmly and the other end is fixedly connected on the inner wall of accommodation groove.In this way, when there is external force that wirerope is pulled to make main axis
It afterwards, will be so that there is flexible deformation in plane scroll spring, so that main shaft keeps the movement tendency to original state；Once and external force
It unclamps, then main shaft will rotate backward under the influence of the restoring force of plane scroll spring, withdraw wirerope.In this way, may make peace
Full device arrangement, installation time-varying it is extremely convenient, and safety after the installation is completed so that wirerope keeps tensioning state, with
Guarantee the practical effect of Subsequent secure device.
It is socketed on the main shaft 2 and is secured to connected rope-winding wheel 21, opened up in the middle part of the side wall of the rope-winding wheel 21
Have an annular groove for accommodating wirerope 3, one end of the wirerope 3 be fixedly connected on the slot bottom of annular groove 21 and
Several circles are arranged in annular groove 21.So that the movement of wirerope is more stable.
The side at the loose slot 521 towards 52 center of flywheel is also provided with deep trouth 522, and the tension spring 55 is placed in deep trouth
In 522, one end of the tension spring 55 is fixedly connected on the slot bottom of deep trouth 522 and the other end is fixedly connected on the middle part of winged pawl 54.
Spindle hole is offered on the flywheel, and spline is offered on the inner wall of the spindle hole, is fixed on the main shaft
It is connected with the spline being adapted to spline, the spline is placed in the spline.To realize that flywheel is synchronous with main shaft
Rotation.
