Embodiment
Below in conjunction with accompanying drawing 1-4 and specific embodiment, utility model is described in further detail:
A kind of pulley fixed frame as Figure 1-4, it pulley 9 comprising a rectangular hanger fixed head 1, be arranged on the double end hanging structure on described suspension bracket fixed head 1 top and be arranged on described suspension bracket fixed head 1 bottom; Described double end hanging structure is used for device to hang between two insulator strings.
As shown in Figure 2, described suspension bracket fixed head 1 top is provided with pocket for the punch head 1-1, reference column 1-4 is provided with in described pocket for the punch head 1-1, it is the duct formed between the second depressed part 1-7 of circular arc or V-type, described reference column 1-4 and described second depressed part 1-7 for installing double end hanging structure bottom described pocket for the punch head 1-1; Described reference column 1-4 cross section is circular.
As shown in Figure 1, described double end hanging structure comprises two hooks be symmetrical set, two hooks all toward the outer side, described hook comprises the semicircular bend 3 be linked in sequence, roundabout projection 5 protruding laterally and elastic joint part 6, the end of elastic joint parts 6 of two hooks is connected by lower nonrigid connector 7, and described lower nonrigid connector 7 is placed in the duct that formed between described reference column 1-4 and described second depressed part 1-7; Bend 3 is for hanging on the insulator steel cap in insulator string or between two full skirts.Described roundabout projection 5 assists bend 3 to block insulator from downside, the end of described bend 3 is provided with extension 2, for ensureing that bend 3 is not by slippage.The end arranged outside of described extension 2 has the little crotch 10 be bent upwards, in time playing the insulator string of heavier-weight, two little crotches 10 can be connected by iron chains or steel wire rope, iron chains or steel wire rope are passed through by insulator string bottom, this ensure that the stable firmly connection of double end hanging structure on insulator string, can not be out of shape slippage, fail safe is high.Described bend 3 is provided with Anti-slip cover 4, and described Anti-slip cover 4 outer wall is provided with the non-slip process 4-1 pointed to inside bend 3, Anti-slip cover 4 and non-slip process 4-1 are rubber layer, for contacting with insulator, play the effect of increasing friction force.
Elastic joint part 6 makes hook have outside elastic force, is forced to retract during use, reduces the spacing between two hooks, then hangs on the insulator, under the effect of elastic joint part 6 elastic force, make hook and insulator close contact, prevent slippage.
Described suspension bracket fixed head 1 bottom is provided with pulley groove 1-2, described pulley 9 is fixedly installed in described pulley groove 1-2, the fixed rotating shaft 1-3 for fixing described pulley 9 is provided with between described pulley groove 1-2, pulley groove 1-2 top is the first depressed part 1-6, first depressed part 1-6 is circular arc depression, is reserved with the space through hawser between the first described depressed part 1-6 and pulley 9.
Also be provided with the upper nonrigid connector 8 upwards arched upward between two described elastic joint parts 6, described upper nonrigid connector 8 is positioned at above described reference column 1-4.When inwardly pressure puts retraction to two hooks, two elastic joint parts 6 act on, lower nonrigid connector 7 and upper nonrigid connector 8 also act on simultaneously, lower nonrigid connector 7 is bent downwardly, due to the effect of the second depressed part 1-7 of circular arc or V-type, make lower nonrigid connector 7 have the space that deformation occurs, and upper nonrigid connector 8 is bent upwards, it also has larger deformation space.Two described elastic joint parts 6, between lower nonrigid connector 7 and upper nonrigid connector 8, surround a closed loop configuration, described reference column 1-4 is placed in this closed loop configuration, on the one hand for limiting double end hanging structure, on the other hand when lifting by crane insulator by pulley 9, suspension bracket fixed head 1 can be made firmly to be connected with double end hanging structure.
Be provided with joint pin 1-5 between described pocket for the punch head 1-1, the lower surface of described joint pin 1-5 is in the arc surface suitable with described upper nonrigid connector 8.Due to when lifting insulator, the weight of whole insulator is pressed on lower nonrigid connector 7 by reference column 1-4, to the machinery of lower nonrigid connector 7, slightly there is higher requirement, and force two hooks to produce pulling force to the inside after easily making it to produce deformation, occur being connected untight phenomenon with insulator, and the setting of upper nonrigid connector 8, add the elastic force that two hooks are outside to a certain extent, avoid loosening, and when lifting insulator, a weight part for insulator is transferred on lower nonrigid connector 7 by the effect of reference column 1-4, another part is transferred on upper nonrigid connector 8 by the effect of joint pin 1-5, and the lower surface of joint pin 1-5 is in the arc surface suitable with described upper nonrigid connector 8, nonrigid connector 8 can be made to keep shape as far as possible, be unlikely to overbending, maintain the active force of nonrigid connector 8 to a certain extent, maintain the shape of whole double end hanging structure entirety and the stable of structure.
