Abstract
The utility model relates to a special crawling ladder for installation and replacement of a high-tension overhead line composite insulator, comprising insulation stair rods and pedals, the upper end of the insulation stair rod is provided with a hook hole for hooking a lifting hook of a pulley block, and the lower end of the insulation stair rod is provided with a connecting piece for articulating a sing-wire and double-wire lifter, the pedals are distributed at two sides of the e insulation stair rod in a staggering way and are fixedly connected with the insulation stair rods or articulated with the insulation stair rods, or articulated with hoops fixed on the insulation stair rods. The special crawling ladder is suitable for single-wire or double-wire operation and has the characteristics of light weight, artistic appearance, simple structure, convenient operation, being beneficial to aloft work, low field application cost, economic usage, stable performance, no need of special maintaining and no limit of natural environments, construction sites and personnel cooperation, wherein the whole weight is only 2kg; the special crawling ladder is an optical combination of various operation tools and solves the operation of the composite insulator indeed.
Description
Technical field
The utility model relates to a kind of cat ladder, especially relates to a kind of high-tension overhead line composite insulator the replacing special ladder is installed.
Background technology
Along with the innovation of science and technology, the continuous development of power grid construction, composite insulator replaces old-fashioned porcelain insulator just gradually, and composite insulator has non-maintaining and characteristics such as life cycle is long.At present, the popularity rate of the synthetic insulator of transmission line has reached 92%.And newly install every year and the composite insulator of replacing increases gradually, need be along operation about the insulator in insulator installation and replacing process.Regulation according to " nominal is higher than 1000V interchange overhead transmission line and uses guide rule with composite insulator " and relevant criterion:, forbid trampling the insulator umbrella cover along in the insulator operation process.In view of afore mentioned rules, installing and change composite insulator uses rope ladder or hard ladder to realize compound inslation subjob up and down at present usually, but in use there are the following problems: when using rope ladder to install to change the compound inslation subjob: rope ladder is transmitting, in the suspension process easily and assembly pulley twine mutually, influence operating efficiency.When using hard ladder that replacing compound inslation subjob is installed: promote in the lead process at assembly pulley, lead touches the pedal of ladder easily, and when range of lift was big, lead can push away ladder, causes the ladder high-altitude to come off, serious threat operating personnel's safety.Work tools such as existing in addition composite insulator special-purpose ladder and assembly pulley rope all are suspended on the cross-arm head, and working range is limited on the cross-arm, and the Work tool that uses is more, and the construction technology complexity is subjected to the restriction of conditions such as meteorological condition, construction environment; Construction technology is more loaded down with trivial details.
The utility model content
The purpose of this utility model is to provide a kind of high-tension overhead line composite insulator to install and changes special ladder, can realize cat ladder and assembly pulley etc. Work tool is organic cooperating, be convenient to that lead promotes and the workmen about operation, effectively avoid in the work progress Work tool to workmen's influence.
For achieving the above object, the utility model is by the following technical solutions:
A kind of high-tension overhead line composite insulator of the present utility model is installed and is changed special ladder, comprise insulating ladder bar, pedal, the upper end of described insulating ladder bar is provided with the hook hole that is used for hook assembly pulley suspension hook, and the lower end of described insulating ladder bar is provided with the connector that is used for hinged single line or two-wire line lifter; Described pedal is interspersed in the both sides of insulating ladder bar.
Above-mentioned high-tension overhead line composite insulator is installed and is changed special ladder, and described pedal and insulating ladder bar are hinged or hinged with the clip that is fixed on the insulating ladder bar.
The beneficial effects of the utility model are: the utility model adopts the upper end of insulating ladder bar to be provided with the hook hole that is used for hook assembly pulley suspension hook, and the lower end of insulating ladder bar is provided with the connector that is used for hinged single, double line line lifter.With assembly pulley, single conductor or the supporting use of two-conductor line line lifter, both can promote lead, can realize the smooth cross-arm up and down of operating personnel again, reduce and change insulator power tool use amount, increase work efficiency.
Adopt that pedal and insulating ladder bar are hinged can be folded to the body of rod with pedal in time spent not, be easy to carry, the clip that adopts and be fixed on the insulating ladder bar is hinged, the spacing between can the free adjustment pedal.
The utility model goes for single conductor or two-conductor line operation. and have in light weight: integral body has only 2kg, and good looking appearance, simple in structure is easy to operate, is beneficial to work high above the ground; The field is with low cost, uses economy, stable performance; Maintaining that need not be special; The characteristics such as restriction that not cooperated by natural environment, construction site, personnel. realize the optimum organization of several work instrument, really solved composite insulator shop problem up and down.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following specification, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Embodiment
As shown in Figure 1 and Figure 2, a kind of high-tension overhead line composite insulator of the present utility model is installed and is changed special ladder, comprises insulating ladder bar 2, pedal 4.The upper end of described insulating ladder bar 2 is provided with the hook hole 1 that is used for hook assembly pulley suspension hook, and the lower end of described insulating ladder bar 2 is provided with the connector 5 that is used for hinged single line or two-wire line lifter.Pedal is interspersed in the both sides of insulating ladder bar.
Pedal can be fixedlyed connected with the insulating ladder bar.Also can be hinged with the insulating ladder bar; Perhaps hinged with the clip 3 that is fixed on the insulating ladder bar.Purpose be easy to carry and the free adjustment pedal between spacing.
When composite insulator 8 is installed, earlier assembly pulley 7 is hung on cross-arm 6, hook hole 1 with insulating ladder bar 2 upper ends hangs on the assembly pulley suspension hook again, again that the connector 5 of insulating ladder bar 2 lower ends is hinged with single conductor or two-conductor line line lifter, lead 9 is placed on the line lifter operation assembly pulley, promote lead, to suitable position, the backguy of locking assembly pulley, the staff can along pedal about in the of 4 cross-arm carry out the composite insulator installation exercise.
When changing composite insulator 8, earlier assembly pulley 7 is hung on cross-arm 6, hook hole 1 with insulating ladder bar 2 upper ends hangs on the assembly pulley suspension hook again, insulating ladder bar 2 lower ends and connector 5 hinged line lifters are hung over lead 9 to be placed on the line lifter, the operation assembly pulley, tension is the backguy of locking assembly pulley also, the staff can along pedal 4 about cross-arm carry out composite insulator replacing operation.
