Specific embodiment
As shown in figs 1-9, including cabinet 1, main shaft 2, wirerope 3, reset assembly and brake assemblies are described for the utility model
Cabinet 1 wears the cabinet 1 and cuts with scissors with cabinet 1 in rope hole, the main shaft 2 is offered on hollow shape and one side surface
Connect, one end of the wirerope 3 and main shaft 2 are fixedly linked and are arranged with several circles outside main shaft 2, the wirerope 3 it is another
End is extend 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 fortune to original state
Dynamic trend；
The brake assemblies 5 include fixing seat 51, flywheel 52, several interior ratchets 53, at least one winged pawl 54 and at least draw
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 in cabinet 1
Offer circular groove on end face, the circular groove and main shaft 2 is concentric and empty set described in main shaft 2, several interior ratchets
53 are evenly arranged on the side wall of circular groove and are fixedly linked with fixing seat 51；The flywheel 52 be set to circular groove in and with master
2 synchronous rotary of axis offers loose slot 521 on the side wall of the flywheel 52, and the root of the winged pawl 54 is articulated with loose slot 521
In, the both ends of the 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 flywheel 52
The movement tendency of center rotation；
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 case
One end outside body 1 and cable 31 or pendant, which stick together, 32 to be connected.
The utility model in actual use, can as shown in figure 9, can first complete the connection that sticks together with cable of pendant (can be in the two
Between pulley blocks are set)；Cabinet is connected on electric pole again (can choose a pair of with the two one according to the quantity that cable, pendant stick together
The safety for the quantity answered)；Finally, pull out wirerope from outside rope hole phase, and complete wirerope and all pendants stick together, all cables
Line is fixedly connected.So that this case is not necessarily to when installing safety while holding cable, hangs pendant and stick together, it is extremely convenient and
Labor intensity is low, security risk is small, have on the whole good delicate structure, stability, good braking effect, installation it is extremely convenient with
And the advantages that errorless Trigger Problems.
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 the influence that main shaft and flywheel will stick together in cable or pendant
Lower beginning high speed rotation is directed away from flywheel so that all winged pawls be made to overcome the active force of tension spring under the influence of centrifugal force
The direction whipping at center, and be finally caught in the gap of adjacent interior ratchet, as shown in figure 5, carrying out effective rotation stop to main shaft.This
Sample, on the one hand, avoid that cable occurs by free-falling the problem of breaking, play effective guarantor to cable
Shield；On the other hand, it also can effectively hold pendant to stick together, avoid pendant and stick together and smash asking for itself and underlying device because of free-falling
Topic；Play the bidirectional protective to stick together to cable and pendant.
