The utility model content
The technical problem that the utility model solves just provides a kind of special-purpose coaster of automatic suspension of the safe ready of seting out.
For solving the problems of the technologies described above, the technical scheme that the utility model hangs special-purpose coaster employing automatically is: comprise insulated hook, blocking mechanism and the insulating block that is positioned at the insulated hook below, described insulated hook is two that fix and be oppositely arranged by first bearing pin, described blocking mechanism comprises tail end and two fixing poles of inboard second bearing pin of described insulated hook, the free end of described two poles is connected by the 3rd bearing pin with the two ends of connecting rod respectively, described connecting rod is provided with through hole, in described through hole, be installed with the first insulation rope, this first insulation rope upper end is connected by hook with described insulated hook, is wound with the second insulation rope in described insulating block.
Its additional technical feature is:
Described through hole is two, and the line of these two through holes is vertical with the plane at two insulated hook places, and the described first insulation rope upper end is two, penetrates respectively in the different through holes.
The special-purpose coaster of automatic suspension provided by the utility model compared with prior art has the following advantages:
One, owing to comprise insulated hook, blocking mechanism and the insulating block that is positioned at the insulated hook below, described insulated hook is two that fix and be oppositely arranged by first bearing pin, described blocking mechanism comprises tail end and two fixing poles of inboard second bearing pin of described insulated hook, the free end of described two poles is connected by the 3rd bearing pin with the two ends of connecting rod respectively, described connecting rod is provided with through hole, in described through hole, be installed with the first insulation rope, this first insulation rope upper end is connected by hook with described insulated hook, in described insulating block, be wound with the second insulation rope, during use, at first insulated flexible ladder ladder head is fixed on the second insulation rope, the free end of the second insulation rope is walked around insulating block, hook is hung on the insulated hook, connecting rod moves up, at this moment, the insulated hook upper end is in opening, throw the free end edge of the first insulation rope over lead perpendicular to the aerial condutor direction, the ground personnel pulling downwards first insulation rope, lead enters between two insulated hooks through the insulated hook openend, pulling along with the first insulation rope, lead is with connecting rod top side below the inside of insulated hook, connecting rod drives pole, pole drives insulated hook and turns to the inside, the upper end of two insulated hooks is stuck in the lead top, spur the free end of the second insulation rope then, insulated flexible ladder is suspended on the lead, the staff climbs to insulated flexible ladder ladder head and goes up work, after finishing dealing with, the staff will link up with from insulated hook and remove and get off along insulated flexible ladder, take automatic special-purpose coaster, upwards spur the free end of the first insulation rope at last, move on the hook drivening rod, move thereby drive on the pole, the rotating shaft of insulated hook upper end edge is rotated and is opened, should hang special-purpose coaster automatically takes off, it is convenient to set out, safety, the suspension rope ladder when this hangs special-purpose coaster automatically and can not only be used for live line working, tool for transmitting material in the time of can also being used on the lead operation; They are two years old, because described through hole is two, the line of these two through holes is vertical with the plane at two insulated hook places, and the described first insulation rope upper end is two, penetrate respectively in the different through holes, like this, move past on insulated hook in the journey, the plane at two insulated hook places is vertical with the lead direction all the time, it is convenient to set out, and the first insulation rope is not easy to be insulated hook and is pressed on the lead, has prevented to restrict and cause the generation of coaster case accident because of rubbing first insulation.
Description of drawings
Fig. 1 hangs the structural representation of special-purpose coaster open state automatically for the utility model;
Fig. 2 hangs the structural representation of special-purpose coaster locking states automatically for the utility model.
Embodiment
Below in conjunction with accompanying drawing structure and the use principle that the utility model hangs special-purpose coaster automatically is described in further details.
As depicted in figs. 1 and 2, the utility model hangs the structural representation of special-purpose coaster automatically, comprise two insulated hooks 2 fixing and be oppositely arranged by first bearing pin 21, between two insulated hooks 2, be provided with blocking mechanism 3, be positioned at insulated hook 2 belows and be provided with insulating block 4.Blocking mechanism 3 comprises two poles 32,33 that the inboard of tail end and insulated hook 2 is fixed by second bearing pin 31, the free end of pole 32,33 is connected by the 3rd bearing pin 35,36 with the two ends of connecting rod 5 respectively, connecting rod 5 is provided with through hole 51, be installed with the first insulation rope 6 in through hole 51, the upper end of this first insulation rope 6 is connected by hook 61 with insulated hook 2.In insulating block 4, be installed with the second insulation rope 7.During use, at first terraced 8 of insulated flexible ladder is fixed on the second insulation rope 7, the free end of the second insulation rope 7 is walked around insulating block 4, to link up with 61 hangs on the insulated hook 2, connecting rod 5 moves up, at this moment, insulated hook 2 upper ends are in opening, lead 9 is walked around perpendicular to lead 9 directions in the free end edge of the first insulation rope 6, the ground personnel pulling downwards first insulation rope 6, lead 9 enters between two insulated hooks 2 through insulated hook 2 openends, pulling along with the first insulation rope 6, lead 9 is with connecting rod 5 tops side below the inside of insulated hook 2, connecting rod 5 drives pole 32,33, pole 32,33 drive insulated hook 2 turns to the inside, the upper end of two insulated hooks 2 is stuck in lead 9 tops, spur the free end of the second insulation rope 7 then, terraced 8 of insulated flexible ladder is suspended on the lead, the staff climbs on the insulated flexible ladder ladder 8 and works, after finishing dealing with, the staff will link up with 61 and remove and get off along insulated flexible ladder from insulated hook 2, take terraced 8 of insulated flexible ladder, spur the free end of the first insulation rope at last, link up with on 61 drivening rods and move, thereby drive pole 32, move on 33, insulated hook 2 upper end edges first bearing pin 21 rotates and opens, should hang special-purpose coaster automatically and take off, it is convenient to set out, safety.
