It is using the beneficial effect produced by above-mentioned technical proposal:
Present configuration is simple, easy to carry.This device is hung on insulator chain by two resilient hooks of tool, Easy to operate, pulley is located at the lower section of whole device, and the center of gravity of device has on the lower, in operating process preferable stability, no Need to worry that device is inclined.The hitch gear of elasticity can adapt to the different insulator chain of intermediate gap width, and in elasticity In the presence of, hook can be made against corresponding insulator chain,
Description of the drawings
Fig. 1 is the cross section structure diagram of the present invention.
Fig. 2 is the cross section structure diagram of suspension bracket fixed plate of the present invention.
Fig. 3 is the side structure schematic view of type suspension bracket fixed plate of the present invention.
Wherein:1 suspension bracket fixed plate, 1-1 pocket for the punch heads, 1-2 pulley grooves, 1-3 fixed rotating shafts, 1-4 locating dowels, 1-5 connecting poles, The depressed parts of 1-6 first, the depressed parts of 1-7 second, 2 extensions, 3 bends, 4 Anti-slip covers, 5 roundabout projections, 6 elastic joint parts, under 7 Nonrigid connector, nonrigid connector, 9 pulleys on 8.
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.
