Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: it comprises that vertical setting is tabular grapple body 1, the tip edge of grapple body 1 links to each other with the transverse slat 2 that is connected that crosses out, the edge that connects transverse slat 2 connects the upper supporting plate 3 that stretches out downwards, there is the gap in upper supporting plate 3 with grapple body 1, transverse strands between upper supporting plate 3 and the grapple body 1 be provided with insulation on cylinder 4, the stage casing of last cylinder 4 increases gradually to its two ends barrel dliameter, make the barrel stage casing of going up cylinder 4 present circumferential spacing depression 5, the bottom of upper supporting plate 3 is lower than the sidewall of going up cylinder 4, and the hypomere of upper supporting plate 3 is the flange shape that outwards launches gradually, connect on corresponding to the stage casing sidewall of the grapple body 1 of upper supporting plate 3 bottom lower positions and be tilted to the lower carrier plate 6 that stretches out down, there are the gap in the bottom of lower carrier plate 6 and grapple body 1, transverse strands is provided with the bottom roll 7 of insulation between the bottom of lower carrier plate 6 and grapple body 1, the sidewall stage casing of bottom roll 7 offers circumferential limited ring groove 8, the sidewall of the both ends of limited ring groove 8 and bottom roll 7 forms step-like, the part of bottom roll 7 two ends sidewalls leans out downwards from the bottom of lower carrier plate 6, is provided with installing hole 9 in the bottom of grapple body 1.
It is circular-arc that the cross section along last cylinder 4 axis directions of described spacing depression 5 is two sections.Lower carrier plate 6 shape bending in obtuse angle, the lower carrier plate 6 of kink below is set in parallel with grapple body 1.
Between upper supporting plate 3 and lower carrier plate 6, be provided with the guided plate 10 of shape bending in obtuse angle, the inner of described guided plate 10 is connected grapple body 1 sidewall, the outer end of guided plate 10 is connected on the kink of lower carrier plate 6, is the tabular of one at lower carrier plate 6 plate bodys of guided plate 10 plate bodys of kink hypomere and kink hypomere.
During use, earlier in installing hole 9, hang up properly rope ladder head, guided plate 10 is leaned against on one power transmission line, bottom roll 7 is above following one power transmission line, last cylinder 4 is above last one power transmission line, and go up one power transmission line between upper supporting plate 3 and grapple body 1, the utility model slowly slides downwards then, in last one power transmission line slips into the spacing depression 5 of cylinder 4, and one power transmission line snaps in the limited ring groove 8 down, because the both ends of limited ring groove 8 and the sidewall of bottom roll 7 form step-like, the bottom of upper supporting plate 3 is lower than the sidewall of going up cylinder 4, and the hypomere of upper supporting plate 3 is the flange shape that outwards launches gradually, makes that one power transmission line snaps in the limited ring groove 8 down, go up and be difficult for skidding off the fail safe when having increased construction after one power transmission line snaps in spacing depression 5.
