Abstract
Provided is a live working insulated cross arm. A hoop is clamped upon an electric pole via a fastening screw. The hoop is evenly provided with three supports in an outward-inclined manner via a support-hoop connecting frame. The upper ends of the supports are provided with support bolt rope heads. A diameter-adjusting hoop, arranged at the upper portion of the hoop, is connected with a central rod at the upper portion of the diameter-adjusting hoop. A support central head is arranged at the upper end of the central rod. A draw cord is connected between the support central head and the support bolt rope heads, with each support bolt rope head being connected with a lifting hook pulley via a rope. The lower portion of the lifting hook pulley is provided with a lifting hook. The live working insulated cross arm allows the live replacement of a lead, is capable of effectively controlling the air gap and safe distance between the lead, cross arm, and other lines set up with the same pole, and features convenient installation, simple operation, and versatility for multi-layer leads, thereby being suitable for live installation of the lead in an electric power transmission device.
Description
Technical field
The utility model provides the power transmission lines fixture of electric field, specifically live line working insulator crossarm.
Background technology
Domestic existing 10kV live line working insulator crossarm can't effectively use at present, exists unsafe drawback, has not only increased operating personnel's hazards but also has not had the requirement that improves power supply reliability again.And need to have a power failure and change insulator crossarm, reduced operating efficiency.
Summary of the invention
In order to overcome the shortcoming of existing insulator crossarm, the utility model provides the live line working insulator crossarm.This cross-arm is through installing leg-of-mutton support on electric pole, installation lifting rope pulley and suspension hook lift lead on each support, solve the technical problem of the charged installation of lead.
The scheme that the utility model technical solution problem is adopted is:
On electric pole, be installed with anchor ear, be separated by 120 ° on the anchor ear, be provided with the stent bolt fag end in the support upper end through support and the outward-dipping support that is equipped with of anchor ear link through jackscrew; Be connected with the diameter adjustment hoop on anchor ear top; Diameter adjustment hoop top is connected with center pole, is provided with the carriage center head in the center pole upper end, is connected with stay cord between carriage center head and the stent bolt fag end; On each stent bolt fag end, be connected with lifting hook pulley through rope, bolt has suspension hook in the bottom of lifting hook pulley.
Good effect, during the utility model charged for replacement lead, the vertical load that original cross-arm is carried lead is transferred on the insulator crossarm, guarantees the lead secure.And utilize up-down on the insulator crossarm device with the height lifting or the reduction in various degree of three-phase conducting wire.The effectively air gap of other circuit of pilot and cross-arm and parallel lines on same tower and safe distance have the advantages that easy for installation, simple to operate, multi-layer conductor leads can both be general.Suiting on power transmission device, to be used for charged installation lead uses.
Description of drawings
Fig. 1 is the utility model insulator crossarm configuration state figure
Among the figure, 0. electric pole, 1. anchor ear, 2. support, 2.1. support and anchor ear link, 2.2. stent bolt fag end, 3. diameter adjustment hoop, 4. carriage center head, 5. stay cord, 6. suspension pulley, 6.1. suspension hook, 7. center pole.
Embodiment
On electric pole, be installed with anchor ear 1 through jackscrew; Be separated by 120 ° on the anchor ear through support and the anchor ear link 2.1 outward-dipping supports 2 that are equipped with; Be provided with stent bolt fag end 2.2 in the support upper end, be connected with diameter adjustment hoop 3 on anchor ear top, diameter adjustment hoop top is connected with center pole 7; Be provided with carriage center 4 in center pole upper end; Be connected with stay cord 5 between carriage center head and the stent bolt fag end, on each stent bolt fag end, be connected with lifting hook pulley 6 through rope, bolt has suspension hook 6.1 in the bottom of lifting hook pulley.
The use of the utility model:
The lead of installing is in advance fastened on suspension hook, and the pulling rope makes the suspension hook setting height of slinging, and carries out charged installation lead.According to the length of cross-arm, through pulling up and the center pole that falls, the angle of support and electric pole is increased or dwindle, thereby change two at a distance of the distance between the support, realize adapting to the requirement of cross-arm length.
Cross-arm is used for the pull-up lead.Length and the rope lengths of regulating pulley top through the degree of tightness stay cord can make unsettled lead reach setting height.
Utilize existing insulator crossarm that it is combined into triangle and sling lead, the characteristic through mechanics is decomposed the vertical load of lead, makes the upper and lower convergent-divergent of lead through stringing again.Can make the vertical range of lead reach suitable operation height.
Be fixed on the fulcrum bottom of discipline lead on the anchor ear of holding electric pole tightly, lock anchor ear, prevent that insulator crossarm from waving with jackscrew.
The characteristics of the utility model:
1, industrial frequency withstand voltage 45KV did not have punch-through in 1 minute.
2, mechanical strength and hot strength reach the specification technique index.
3, insulation property reach the specification technique index.
4, restringing under can electriferous state.
When the utility model can the charged for replacement lead, the vertical load that original cross-arm is carried lead was transferred on the insulator crossarm, assurance lead secure.And the up-down on the insulator crossarm device capable of using is with the height lifting or the reduction in various degree of three-phase conducting wire.The effectively air gap of other circuit of pilot and cross-arm and parallel lines on same tower and safe distance have the advantages that easy for installation, simple to operate, multi-layer conductor leads can both be general.Overcome the difficulty of all straight line poles replacing cross-arms.
