Description
Technical field
The utility model relates to a kind of distribution line and lays aid, specifically refers to a kind of wiring pruner for tree.
Background technology
From step-down substation, electric power is delivered to distribution transformer or the electric power of distribution transformer is delivered to the circuit of electric unit and called distribution line.Distribution circuit electric voltage is 3.6kV ~ 40.5kV, claims high-tension distributing line; Distribution voltage is no more than that 1kV, frequency are no more than 1000Hz, direct current is no more than 1500V, claims low-voltage distributing line.The construction requirements of distribution line is safe and reliable, keeps power supply continuity, reduces line loss, improves power transmission efficiency, guarantees that the quality of power supply is good.At present, distribution line goes through streets and alleys becomes common phenomenon, but the tree line contradiction existing between distribution line and the trees for urban beautification is day by day deepened, the trees of distribution line downside particularly, therefore, the tree trimming of distribution line downside becomes the key of city line safety work, its free growth if leave, self growing of trees probably touches circuit, cause the stressed breakage of circuit or directly cause phase fault, not only can cause that the most power supply in city ends, also can fire hazard when serious; In addition, on tree body with high-tension electricity fail to be convened for lack of a quorum and injure passing pedestrian, and cause huge threat for the staff's of maintenance circuit personal safety, so the trees of distribution line downside must reasonably be pruned.Traditional processing mode is before laying-out, manually uses the apparatuses such as cutter to prune the branch on distribution line or trees, but this class methods operational hazards, staff's personal safety can not be guaranteed; Another kind of is to modify by high-altitude operation vehicle, and this kind of mode is simple to operate, and safety coefficient is high, but the use cost of high-altitude operation vehicle is high, and suitable environment limitation is high.
Utility model content
The purpose of this utility model is to provide a kind of wiring pruner for tree, and fast and easy is pruned the tree crown under the construction of line, reduces when pruning cost, can guarantee that the branch of manually treating on the ground pruning carries out safety operation.
The purpose of this utility model is achieved through the following technical solutions:
A kind of wiring pruner for tree, comprise support bar and base, the top of described support bar is provided with cutter, a side at base is hingedly connected with hanged hook, described hanged hook middle part offers a gap, and described cutter is over against this gap location, in base, have the rectangular opening that runs through upper and lower two ends, on the both sides inwall of rectangular opening, have a plurality of grooves, in groove, be installed with sleeve pipe, in sleeve pipe, slide and be provided with turning rolls, between sleeve pipe and turning rolls, spring is installed, roller and runner are installed on turning rolls, and a plurality of described roller in the vertical directions are symmetrically distributed in the both sides of runner, described runner contacts with the outer wall of support bar, roller and support bar interval arrange.During the utility model work, manually support bar is lifted, when cutter arrives branch to be cut, hanged hook blocks the trunk of branch, according to the size of branch diameter to be cut, can directly hanged hook be close to the corner dimension that branch regulates hanged hook and vertical direction, after trunk has been cut, the a part of trunk being cut off can fall, the middle part of hanged hook offers a gap, the swing cutting of cutter to trunk, during cutting, base is fixed on branch by hanged hook, support bar moves up and down in rectangular opening, the runner contacting with support bar is free to slide on support bar outer wall, to realize the cutting of cutter to branch, when cutter is during by the certain degree of depth of branch cutter, can there is certain inclination in cutter itself, now support bar presses down the runner on rectangular opening one side inwall, runner is moved to the direction of blind hole bottom, and runner on the inwall of rectangular opening both sides keeps the rolling clamping to support bar always, reduced to a great extent staff's labour intensity, after cutting, the utility model can not fall with the trunk cutting down, avoid the utility model unexpected impaired, improve the safety reliability in operating process, when branch soon cuts when complete, support bar respectively with the roller of a side runner top, the roller contact of opposite side runner below, to realize the cutter conversion of angle on a large scale, in whole process, by hanged hook, whole device is got up in trunk upper support, artificial only need up and down or inclination movable support bar, can realize effective cutting of cutter to branch, the runner arranging in rectangular opening and roller can guarantee in comparatively complicated tree body environment, make cutter to all kinds of difform branches or trunk carries out fly-cutting, reduce the consumption of artificial muscle power, guarantee the safety under cutting environment simultaneously.
Described support bar comprises upper boom and lower beam, described upper boom is connected with cutter through rectangular opening, in lower beam, be provided with rectangular recess, the rectangle of the cross section of upper boom for matching with described rectangular recess, the lower end of upper boom is arranged in rectangular recess, on lower beam, have a plurality of through holes, be provided with the connecting hole corresponding with through hole on upper boom, connecting hole is connected with through hole by bolt.Upper lower beam is flexibly connected, and can make the utility model installing/dismounting fast, also installing a support bar compared with rise additional during from the cutting of branch, has greatly improved practicality of the present utility model.
Described cutter comprises vane body, on described vane body top, is equipped with and the orthogonal side blade of vane body.Vane body is serrated edge, and the side blade of installing at the two ends of vane body can directly cut the branch of small diameter, and for cutting large diameter trunk cleaning space, strong raising pruned efficiency.
Also comprise the spacing collar that is arranged on upper boom top.When manually moving up and down lower beam, upper boom slides up and down between two runners, and the top of upper boom and the junction of vane body are easy to bump with base, make vane body be subject to larger damage, at the spacing collar at upper boom top, can avoid vane body to contact with base, prevention causes the impaired of vane body after manually excessively pullling lower beam.
The utility model compared with prior art, has following advantage and beneficial effect:
1, a kind of wiring pruner for tree of the utility model, in whole process, by hanged hook, whole device is got up in trunk upper support, artificial only need up and down or inclination movable support bar, can realize effective cutting of cutter to branch, the runner arranging in rectangular opening and roller can guarantee in the tree body environment of complexity comparatively, makes cutter to all kinds of difform branches or trunk carries out fly-cutting, reduce the consumption of artificial muscle power, guarantee the safety under cutting environment simultaneously;
2, a kind of wiring pruner for tree of the utility model, vane body is serrated edge, and the side blade of installing at the two ends of vane body can directly cut the branch of small diameter, and for cutting large diameter trunk cleaning space, strong raising pruned efficiency;
3, a kind of wiring pruner for tree of the utility model, upper boom slides up and down between two runners, and the top of upper boom and the junction of vane body are easy to bump with base, make vane body be subject to larger damage, at the spacing collar at upper boom top, can avoid vane body to contact with base, prevention causes the impaired of vane body after manually excessively pullling lower beam.
