The live-working insulating hook ladder door-sealing hook comprises an insulating hook ladder (2), an insulating hook ladder hook (2-1), insulating plates (7) and a rope hanging wheel (5). A semi-round groove (7-1) matched with an aluminum wire (1) is arranged above the two symmetric insulating plates (7), the left side of the middle portion of each insulating plate (7) is provided with an insulating plate sliding rail (8), the two insulating plates (7) are arranged on two sides on the upper portion of the insulating hook ladder (2) respectively through a bolt shaft (3) and fixing nuts (9), the bolt shaft (3) and the fixing nuts (9) are arranged in the insulating plate sliding rail (8), the lower portions of the insulating plates (7) are strengthened through a fixing shaft (6) and fixing bolts (9), two ends of the bolt shaft (3) are connected with tension springs (10), the left side of each insulating plate (7) is connected with an insulating rope (4), the other end of each tension spring (10) is connected with a rope hanging wheel (5), and the insulating ropes (4) wind around the rope hanging wheel (5) to pull the insulating plates (7) to slide left and right. The live-working insulating hook ladder door-sealing hook guarantees safe work of operators, is convenient to use, and improves work efficiency.

Description

The live line working insulated hook ladder drag hook of sealing up a door
Technical field
The utility model belongs to power industry power transmission and transformation maintenance apparatus, particularly a kind of live line working insulated hook ladder drag hook of sealing up a door.
Background technology
Move in the professional transformer station hotline maintenance process in the electric power system power transmission and transformation, need specific purpose tool to carry out charged installing/dismounting bus drainage thread, and the insulated hook ladder that these instruments are insulating material to be made, and insulated hook ladder does not have folding to seal up a door after hanging on the bus, thereby insulated hook ladder landing from the bus is got off, so that the operating personnel aloft feels is dangerous, the operating personnel worries the ladder landing, has certain risk.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, and live line working insulated hook ladder a kind of simple in structure, safe and reliable, the easy to use drag hook of sealing up a door is provided.
The technical scheme that the utility model technical solution problem adopts is: the live line working insulated hook ladder drag hook of sealing up a door comprises insulated hook ladder, the insulated hook ladder hook, insulation board, the rope change gear, be characterized in above the insulation board of two symmetries, being provided with the semi-circular groove that cooperates with aluminum conductor, the left side, place is provided with the insulation board slideway in the middle of insulation board, two both sides, top that insulation board is contained in insulated hook ladder with the bolt shaft in the insulation board slideway and hold-down nut, below insulation board, reinforce with fixed axis and set bolt, two ends in bolt shaft connect extension spring, connect insulation ropes at the insulation board upper left side, on the extension spring other end connecting rope change gear, insulation ropes is walked around rope change gear pulling insulation board and is horizontally slipped.
The beneficial effects of the utility model are: the live line working insulated hook ladder drag hook of sealing up a door can erect insulating ladder and aims at lead and hang, automatically envelope position lead can not eject in lead enters drag hook, after the operation personnel end of job, arrive ground down, pull the envelope hook by insulation ropes, opening, the Ground Operation personnel can mention hanging ladder to next setting, make operator safety work by insulation board slideway rotation drag hook nature, easy to use, increase work efficiency.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is the live line working insulated hook ladder drag hook structure chart of sealing up a door.
Among the figure, the 1-lead; The 2-insulated hook ladder; 2-1-insulated hook ladder hook; The 3-bolt shaft; The 4-insulation ropes; The 5-change gear that insulate; The 6-fixed axis; The 7-insulation board; 8-insulation board slideway; The 9-hold-down nut; The 10-extension spring.
Embodiment
Embodiment, with reference to accompanying drawing 1, the live line working insulated hook ladder drag hook of sealing up a door adopts two insulation boards 7 with shape, and a side is provided with semi-circular groove 7-1 above insulation board 7.Left side, middle part at insulation board 7 is provided with the insulation board 7 usefulness bolt shaft 3 of 8, two symmetries of rectangular insulation board slideway and the both sides that hold-down nut 9 is fixed on insulation board 7 by the insulation board slideway insulated hook ladder 2.Bolt shaft 3 can horizontally slip in insulation board slideway 8, and insulation board 7 belows are fixing with insulated hook ladder 2 with fixed axis 6 and hold-down nut 9.Connect an end of extension spring 10 in the two ends of bolt shaft 3, the left end middle part of insulation board 7 connects an end of insulation ropes 4, extension spring 10 other end connecting rope change gears 5, and the other end of insulation ropes 4 is walked around rope change gear 5 with operating personnel.When insulated hook ladder hook 2-1 hangs on the aluminum conductor 1, semi-circular groove 7-1 on the insulation board just in time coincide with lead 1, drag hook can seal lead 1 automatically, it is following to ground after the operation personnel finish, pull the envelope hook by insulation ropes 4, by insulation board slideway 8, drag hook is opened naturally, namely can mention insulated hook ladder 2.
