Abstract

The invention relates to the field of power line repair and in particular relates to an insulating long reach chain saw. The insulating long reach chain saw comprises a long shank and a short shank, wherein the long shank is fixed on an insulating rod; the front end of the long shank is pivoted to the short shank; a movable pulley is arranged on the tail end of the long shank; a spring is further arranged between the long shank and the short shank; a fixed pulley is arranged on the insulating rod; the fixed pulley is in linkage connection with the movable pulley by use of an insulating rope.

Description

A kind of insulating pruning shears
 
Technical field
 
The present invention relates to electric power first-aid field, refer in particular to a kind of insulating pruning shears.
 
Background technology
Along with city is constantly expanded and the improving constantly of people's living standard; 10kV, 0.4kV distribution line structure becomes increasingly complex; different from transmission line; the height of distribution line is general all at below 13m; and much concentrate on the denser population districts such as rural area, cities and towns, also often have the greenbelts such as trees below circuit.Along with the continuous growth of the plants such as trees, often outlet can set the defect such as short, tree threading, phase fault time serious, can be caused to cause the accident such as line tripping or neighbouring casualties.Except the vegetation such as trees have very large threat to distribution line, the various house refuses of modern city also can the generation of on the contrary electric power accident, as metallic film, metal iron wire, kite etc., under the elemental effects such as strong wind, easily with hang or be wrapped in above alive circuit, become accident potential.
Timely, safe pruning is carried out to the branch near controller switching equipment, circuit and becomes the effective ways solving greenbelt and reliable power supply contradiction.At present, existing beta pruning instrument all needs under circuit power-off condition, just can carry out operation, have a significant impact power supply reliability; Live line working generally adopts overhead vehicle mode to carry out, and has certain requirement to operational environment.
Generally we need in power failure and after carrying out safety measure, could start to remove the trees near circuit and foreign material.So not only need labor intensive, material resources, key also needs to carry out power failure operation, causes very large economic loss.The present inventor makes further research this, develops a kind of insulating pruning shears, when not having a power failure, can remove branch, foreign material etc., thus improves the cost of line upkeep and operation.
 
Summary of the invention
To achieve these goals, technical scheme of the present invention is as follows:
A kind of insulating pruning shears, comprise link rod, scissors, described scissors is arranged on the end of link rod.
Further, described scissors manually cuts, comprise long-cutter holder, short sword handle, described short sword handle is fixed on link rod, and the front end of described long-cutter holder is articulated on short sword handle, the end of long-cutter holder is provided with movable pulley, and be also provided with spring between long-cutter holder and short sword handle, described link rod is provided with fixed pulley, is connected by insulating cord between described fixed pulley and movable pulley.
Further, one end of described insulating cord is fixed on fixed pulley, and the other end be arranged in parallel through fixed pulley and link rod again through after movable pulley.
Further, described scissors is driven shearing, and described driven shearing is controlled by infrared remote-control emitter.
Further, described link rod is telescopic.
After adopting such scheme, the present invention compared with prior art, has the following advantages:
When circuit does not have a power failure, pollard can be carried out and removes the work such as foreign material.By selecting link rod and insulating cord length flexibly, the safe distance between operating personnel and charging equipment can be regulated.
 
Accompanying drawing explanation
Fig. 1 is the schematic diagram that the present invention manually cuts;
Label declaration
Link rod 1, long-cutter holder 2, short sword handle 3, movable pulley 4, fixed pulley 5,
Spring 6, insulating cord 7.
 
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
As shown in Figure 1, the one insulation branches of tall trees that the present invention discloses manually are cut, comprise long-cutter holder 2, short sword handle 3, insulating cord 7, described short sword handle 3 is fixed on link rod 1, and the front end of described long-cutter holder 2 is articulated on short sword handle 3, and long-cutter holder 2 and short sword handle 3 coordinate blade can form the structure of a scissors.
The end of long-cutter holder 2 is provided with movable pulley 4, and be also provided with spring 6 between long-cutter holder 2 and short sword handle 3, described link rod 1 is provided with fixed pulley 5, and one end of insulating cord 7 is fixed on fixed pulley 5, and the other end be arranged in parallel through fixed pulley 5 and link rod 1 again through after movable pulley 4.
Pull insulating cord 7, scissors mouth rapid closing, unclamps insulating cord 7, and under the effect of spring 6 pulling force, scissors recovers nature.By extending link rod 1 and insulating cord 7 length, operating radius can be expanded.
If adopt driven shearing (can adopt on market common), then primarily of three part compositions: driven shearing, link rod 1, operating grip, driven shearing is primarily of formations such as blade, change-speed gearing, brushless motor, receiver of remote-control sytem, lithium batteries, driven shearing is connected by link rod 1 with operating grip, operating grip is arranged on link rod 1 lower end, installation infrared remote control transmitter, realizes controlled in wireless to scissors.
Above are only specific embodiments of the invention, but design concept of the present invention is not limited thereto, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should belong to the behavior of invading scope.
