Described inverted triangle plate is L-square, and a right-angle side of described L-square is connected to mainboard bottom, and the hypotenuse of L-square is towards outer lower side.Block board can solve the little problem of area that can be used for supporting on cross-arm with set square.This block board can regulate according to concrete cross arm of tower length, be directly used in frame at cross arm of tower place, improve the height of line lifter, thereby for using elevating screw to reserve enough spaces, applied widely for various shaft towers, the more important thing is, meet live line working requirement, the upkeep operation of can being correlated with in the situation that circuit is charged.
Drive the controlling organization of swivel nut rotation to be provided with to upgrade, neutral gear and under three gears that lower category, can use at work according to specific needs corresponding gear, convenient flexibly.
The length of described mainboard is more than or equal to 1440mm.By the data of searching and field exploring, the length of existing cross arm of tower is the longest is 123cm, and main board length is got and is more than or equal to 1440mm, can reserve sufficient length elevating screw is installed.
Described mainboard adopts aluminum alloy materials to make.Aluminum alloy materials density is low, and quality is light, easy to carry in maintenance repair work, has good corrosion stability, and the recyclable recycling of waste material can energy efficient can prevent again the public hazards that discarded object causes, and meets the requirement of environmental protection.
Beneficial effect of the present invention is:
Ultra-high-tension power transmission line linear pattern steel tower live line working overhead ground wire lifting device of the present invention has reasonable in design, volume is little, the feature such as lightweight, the work that promotes ground wire on shaft tower only needs a people to carry out just can, not only simple and fast safety again, and greatly reduce the operating time of staff on shaft tower, daily this type of need of work is about 120 minutes, now adopt this instrument only to need 20～30 minutes, greatly improve operating efficiency, reduced work risk simultaneously, meet very much the demand of our present stages to man-machine efficacy and daily employee work safety.Reducing under the main trend of interruption duration, live line working is growing on and on simultaneously, and former Method and kit for all cannot meet the requirement of live line working, and this Work tool does not have the rectangular chain metal of similar Lever Blocks, can in the situation that circuit is charged, carry out operation, successful, is worthy to be popularized.
