Specific embodiment
Below in conjunction with the accompanying drawings 1-3 and specific embodiment are described in further detail to invention：
A kind of replacing strain insulator parsing davit as Figure 1-3, it includes a rectangular hanger fixed plate 1, arranges
In the hitch gear and the pulley 9 for being arranged on the bottom of suspension bracket fixed plate 1 on the top of suspension bracket fixed plate 1；The hook machine
Structure is used to device is hung between two insulator chains.
The described top of suspension bracket fixed plate 1 is provided with pocket for the punch head 1-1, and in the pocket for the punch head 1-1 locating dowel 1-4 is provided with,
The pocket for the punch head 1-1 bottoms are the second depressed part 1-7 of circular arc or V-type, locating dowel 1-4 and the second depressed part 1-
Formed between 7 for the duct of mounting hook mechanism；The locating dowel 1-4 section is circle.
Described hitch gear includes two hooks being symmetrical set, and two are linked up with towards outside, the hook
Roundabout projection 5 and elastic joint part 6 including the semicircular bend 3 being linked in sequence, raised laterally, two hooks
The end of elastic joint part 6 is connected by lower nonrigid connector 7, and described lower nonrigid connector 7 is placed in described locating dowel 1-4
In the duct formed and the second depressed part 1-7 between；On the insulator steel cap that bend 3 is used to hanging in insulator chain or
Between two full skirts of person.Described roundabout projection 5 assists bend 3 to block insulator from downside, and the end of the bend 3 sets
Extension 2 is equipped with, for ensureing that bend 3 is not slipped.Elastic joint part 6 makes hook have outside elastic force, when using
It is forced to retract, the spacing reduced between two hooks is then hung up on insulator, in the presence of the elastic force of elastic joint part 6,
Hook is in close contact with insulator, prevent from slipping.
The described bottom of suspension bracket fixed plate 1 is provided with pulley groove 1-2, and the pulley 9 is fixedly installed on the pulley groove 1-2
In, the fixed rotating shaft 1-3 for fixing the pulley 9 is provided between the pulley groove 1-2, pulley groove 1-2 tops are first
Depressed part 1-6, the first depressed part 1-6 are circular arc depression, be reserved between described the first depressed part 1-6 and pulley 9 through
The space of hawser.
The upper nonrigid connector 8 for arching upward upwards, the upper elastic connection are additionally provided between two described elastic joint parts 6
Body 8 is located at locating dowel 1-4 top.When two are linked up with puts retraction to internal pressure, two elastic joint parts 6 are acted on, lower elasticity
Connector 7 and upper nonrigid connector 8 are also acted on simultaneously, and lower nonrigid connector 7 is bent downwardly, due to the second of circular arc or V-type
The effect of depressed part 1-7 so that lower nonrigid connector 7 has the space for deforming upon, and upper nonrigid connector 8 is bent upwards,
It also has larger deformation space.Described two elastic joint parts 6, between lower nonrigid connector 7 and upper nonrigid connector 8
The loop configuration of a closure is surrounded, described locating dowel 1-4 is placed in the loop configuration of the closure, on the one hand for limiting extension
Hook mechanism, on the other hand when insulator is played by pulley 9, can be such that suspension bracket fixed plate 1 firmly connects with hitch gear
Connect.
Connecting pole 1-5 is provided with described pocket for the punch head 1-1, the lower surface of the connecting pole 1-5 is in and the upper elasticity
The arc surface that connector 8 is adapted.Because when insulator is lifted by crane, the weight of whole insulator is pressed by locating dowel 1-4
On lower nonrigid connector 7, slightly there is higher requirement to the machinery of lower nonrigid connector 7, and be easily allowed to produce shape
Force two to link up with to inner side after change and produce pulling force, occur being connected untight phenomenon with insulator, and upper nonrigid connector 8
Arrange, two are increased to a certain extent and links up with outside elastic force, it is to avoid loosened, and when insulator is lifted by crane,
A weight part for insulator is transferred on lower nonrigid connector 7 by the effect of locating dowel 1-4, and another part is by connecting pole 1-5
Effect be transferred on nonrigid connector 8, and the lower surface of connecting pole 1-5 with the upper nonrigid connector 8 in being adapted
Arc surface, nonrigid connector 8 can be made to keep shape as far as possible, be unlikely to overbending, maintain to a certain extent
The active force of upper nonrigid connector 8, maintains the shape of whole hitch gear entirety and stablizing for structure.
Anti-slip cover 4 is provided with described bend 3, described Anti-slip cover 4 is rubber layer, for contacting with insulator,
Play a part of increasing friction force.
Finally it should be noted that：Above example only to illustrate technical scheme, rather than a limitation；Although
The present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It still may be used
To modify to the technical scheme described in previous embodiment, or equivalent is carried out to which part technical characteristic；And
These modifications are replaced, and do not make the spirit and model of the essence disengaging embodiment of the present invention technical scheme of appropriate technical solution
Enclose.
