Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

Embodiment one：Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of elevator governor cable Clamping device, including sensor 1；With the driver plate 7 that sensor 1 can be made to be fixed on the end of expansion link 2；Sensor 1, expansion link 2, Wiring group 8 and driver plate 7 are all symmetrical with the transverse horizontal center line of the fixed plate 19, wherein the symmetrical portion of the driver plate 7 Dividing only has the larger planar ends of face one in top, removes the redundance of driver plate 7, only retains relatively necessary structural region, i.e., The total tune of total work limitation rate is ensure that, in turn ensure that not having unnecessary structure occupies limited work sky Between；

In one embodiment：Wiring group 8 is distributed with horizontal circle last week of expansion link 2；One side end face of driver plate 7 is downward It is shank of the key 17 that side, which extends vertically position, and the afterbody of shank of the key 17 triggers to form locking hook 16 naturally；Locking hook 16 and locking button 18 are reached The space of the irregular figure with arc buffering side is formed during locking states with shank of the key 17, cable can be in the sky of irregular figure Passed through in gap, or the endless rope cable clip for encompassing two or more is held and is locked in the space, provided for cable The space placed and fixed, it can quickly shorten the reaction time when carrying out necessary work to cable, and locking hook 16 exists with pin joint 18 mutual locking of locking button on the inner face of shank of the key 17；

In one embodiment：The fixed plate 19 of driver plate 7 and lower section, which is fixed, is welded into rigid entirety, and is opened in fixed plate 19 Tying up hole 3 provided with rectangle；With the rotating shaft 11 that the lower section upper surface of fixed plate 19 is fixed on by spacing connecting rod 12；Spacing connecting rod 12 It is fixedly mounted on the axis of rotation point of rotating shaft 11 inside rotating shaft 11, and fixation is screwed with fixed plate 19 through rotating shaft 11, simultaneously There is gap between spacing connecting rod 12 and fixed plate 19, can quickly shorten the reaction time when carrying out necessary work to cable, Because providing independent rotation space when the connecting rod 12 of friction belt turn axle 11 or spacing rotates during cable folding and unfolding, work will not be caused to hinder Gear；

In one embodiment：Wherein, it is fixedly mounted, and protrudes from solid at fixed plate 19 of the stop wheel 10 above rotating shaft 11 One end of fixed board 19；Stop wheel 10 and rotating shaft 11 all protrude from the end of fixed plate 19, and its rotating shaft 11 protrudes from both ends, and stop Wheel 10 protrudes from one end, according to both build relative sets, on the premise of work is not influenceed, can most reach effective work On the basis of the work structuring of efficiency, integrally-built working strength can be increased, ensure the steadiness of cable clamping；

In one embodiment：There is relative brake axle 9 parallel with itself in the left side of stop wheel 10；With for increasing stop wheel 10 and the frictional force of brake axle 9 resistance set 4；Resistance set 4 is connected with rotating handle 5；And the both ends of the rotating handle 5 be all embedded with it is anti- Skidding film 6；And the driver plate 7 that rotating handle 5 is fixed with bottom is connected；

In one embodiment：The back side of fixed plate 19 is installed with the anti-abrasion pad for reducing the wear intensity of compression spring 14 Piece 13；With the compression plate 15 with being arranged on the wear-resistant gasket 13 at both ends, compression spring 14 is connected.

Operation principle：Firstly, it is necessary to rotated by grasping rotating handle 5, when rotating handle 5 is rotated into opposite direction, with opening The damping capacity of the bigger slipmat film 6 of close angle degree is stronger, after the completion of work, after being applied to the power disappearance on rotating handle 5, prevents Skidding film 6 can force and drive rotating handle 5 to return to original position, and rapidly that cable is locked in brake axle 9 and rotating shaft Between 11；After rotating handle 5 is opened, coupled resistance set 4 is synchronously brought away from, and is dropped expansion link 2, is rotated wiring group 8 Maximal clearance is expanded to, cable carries over to the end that wiring group 8 is wound in the expansion gap of wiring group 8, then reflexed is from rotating shaft Along rotating shaft 11 progressively up, then S-type covered from resistance in 4 penetrates, after penetrating action, resistance set 4 resets rapidly, hinders for 11 bottom Gap between set 4 and brake axle 9 is filled up by cable simultaneously, then reversely S-type is worn from the gap of brake axle 9 and stop wheel 10 Extended up after entering above stop wheel 10, can penetrate in tying up hole 3 and reversely penetrate again in the wiring group 8 of top, also can be direct Penetrated from the direction of wiring group 8, subsequent cable connects up other work structuring of elevator naturally, in the detection of sensor 1 Under cable in two-part wiring group 8 running situation, and monitoring both ends cable upper and lower ends force direction whether one Cause, if elevator breaks down, the unbalance top cable of active force of both ends cable is still in rising, and lower pulling force occurs in lower section, The sensor 1 at both ends can force safety tongs or associated safety knot by the security system for inputing to limiter of speed of electronic signal Structure carries out mechanical braking to elevator.

Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art Say, it can still be modified to the technical scheme described in foregoing embodiments, or which part technical characteristic is entered Row equivalent substitution, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc., all should Within the scope of protection of the utility model.
