Description
Technical field
The utility model relates to the live line working technical field, relates in particular to an a kind of distant place and enters the special-purpose coaster of equipotential.
Background technology
At present, it is more that various electric pressure live line working enter equipotential method of operation, but operative employee's utensil is less relatively, more tower such as compact tower are particularly arranged, equate to take these methods can't satisfy enough safe distances in cat head tower, the wineglass tower, therefore need enter from " distant place " of distance body of the tower certain distance.So-called " distant place enters " is exactly from climbing to the insulator string side along lead again on the lead and carry out operation with hanging indigo plant (chair lift) or crank arm hard ladder upward behind lead, being sitting in apart from the place beyond the insulator string 1.5m along line direction.For the compact type tower window, when conductor wire end coaster and wire clamp centre distance are 5.5m, take advantage of hanging basket " distant place enters " equipotential can guarantee that operating personnel's minimum combination gap is far longer than 4m, to guarantee the safety of operation.The method can be applicable to phase and the various towers of 220kV circuit in cat head tower, the wineglass tower equally.At present, when ultra-high-tension power transmission line enters equal potential working, all adopt common block mostly, therefore have bigger task difficulty and danger.
Summary of the invention
The purpose of this utility model be to overcome above-mentioned shortcoming and provide a kind of safe, enter equal potential working and be easy to a distant place and enter the special-purpose coaster of equipotential.
A distant place of the present utility model enters the special-purpose coaster of equipotential, comprise insulation board A, insulation board B, insulation board C, aluminium pulley, insulating block and insulation safeguard, wherein: insulation board B is connected with insulation board A by bolt A and bolt B, and bolt A passes the aluminium pulley and is fixed between insulation board B and the insulation board A; Insulation board C is connected with insulation board A by bolt C, bolt D and bolt E, and bolt D passes insulating block and is fixed between insulation board C and the insulation board A; The insulation safeguard is movably connected by bolt F and insulation board B, and its length is greater than the distance between bolt F and the bolt C; Spring one end is fixed on by bolt G that insulation board B goes up, the other end is fixed on the insulation safeguard by bolt H.
An above-mentioned distant place enters the special-purpose coaster of equipotential, and wherein: the insulation safeguard is provided with recess, and C cooperates with bolt.
The utility model is compared with prior art, has the following advantages, as can be known from the above technical solutions, after opening coaster insulation safeguard, the aluminium pulley hangs on the lead, and insulating block is used for placing the lifting rope, implements a distant place on the lead safely and enters the equipotential operation thereby can hang over easily.Under the less situation of tower head size, can directly enter equipotential carry out live line working tower and circuit, " distant place the enters equipotential " mode that makes is further popularized, for the development of hot line maintenance technology provides more supports.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to enter embodiment, structure and the feature of the special-purpose coaster of equipotential according to the distant place that the utility model proposes, describe in detail as after.
Referring to Fig. 1-2, a distant place enters the special-purpose coaster of equipotential, comprise insulation board A1, insulation board B11, insulation board C13, aluminium pulley 7, insulating block 8 and insulation safeguard 9, wherein: insulation board B11 is connected with insulation board A1 by bolt A2 and bolt B 3, and bolt A2 passes aluminium pulley 7 and is fixed between insulation board B11 and the insulation board A1; Insulation board C13 is connected with insulation board A1 by bolt C4, bolt D5 and bolt E6, and bolt D5 passes insulating block 8 and is fixed between insulation board C13 and the insulation board A1; Insulation safeguard 9 is movably connected by bolt F10 and insulation board B11, so that insulation safeguard 9 is that rotate arbitrarily in the axle center with bolt F10, its length is greater than the distance between bolt F10 and the bolt C4, thereby assurance bolt C4 can block insulation safeguard 9 to stop its rotation; Spring 16 provides power for the revolution of insulation safeguard 9, and spring 16 1 ends are fixed on by bolt G14 that insulation board B11 goes up, the other end is fixed on the insulation safeguard 9 by bolt H15.
During use: place on the handle hole 12 with a little rope or action bars, insulation safeguard 9 is rotated around bolt F10, thereby manually push insulation safeguard 9 aside, afterwards lead is put on the aluminium pulley 7 along the breach between insulation board B11, the insulation board C13, whole coaster is hung on the lead.Unclamp insulation safeguard 9, under the effect of spring 16 power, insulation safeguard 9 meeting auto-closings, and be stopped at bolt C4 position, to prevent that in the course of work, lead skids off coaster.Transmit rope and pass,, realize the transmission up and down of article by the rotation of insulating block 8 from insulating block 8 and the space in the middle of the bolt C4.In operating process, can adjust the position of coaster on lead by the rotation of aluminium pulley 7.After operation is intact, the action that need repeat to open, the safeguard 9 that will insulate is opened, and makes coaster break away from lead.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any technical solutions of the utility model content that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
