Abstract
The utility model relates to an insulated pruning saw comprising a brake pull-rod and a handsaw. The insulated pruning saw is characterized in that a detachable clamping sleeve (2) is installed on a T-shaped head (11) of the brake pull-rod (1), the clamping sleeve (2) comprises a component for clamping the T-shaped head (11) and a device for fixing the handsaw, and the handsaw can be demounted from the clamping sleeve (2). The pruning saw can be used for performing tree pruning and cutting operations under the condition that the circuit is not powered off, so that the circuit power distribution reliability is improved; and a lengthened insulated operating rod is adopted, so that the operation of climbing trees by personnel is reduced and the security of tree pruning operation personnel is improved.
Description
Technical field
The utility model relates to a kind of electrician's instrument, is specifically related to a kind of insulation trim saw, is particularly useful under not power failure of circuit situation, carrying out trees pruning operation.
Background technology
Electric line operates in the field, receives the influence of superelevation trees through regular meeting, and superelevation trees contact wire meeting causes discharge.This discharge meeting damage wires increases electric energy loss, jeopardizes near the personal security that stops the trees, and can cause the electric line tripping operation.To near the pruning of the superelevation trees electric line, be the important process that electric line is safeguarded, also be the necessary means that ensures the electric line safe and stable operation.Now, the instrument that near the pruning of the superelevation trees electric line is used is handsaw, in the time of carrying out superelevation tree trimming operation, is protection operating personnel's safety, mostly is to have a power failure to carry out, and has increased the power off time of electric line, has reduced power supply reliability; Simultaneously must climb the trees operation by manual work, the operating personnel brings potential safety hazard to the trees pruning.
Summary of the invention
Need have a power failure and climb the safety problem that trees bring constantly in order to solve carrying out open-air pruning operation, the utility model provides a kind of and climbs can the prune insulation trim saw of operation of trees in the operation and need not of need not to have a power failure.
A kind of insulation trim saw that the utility model provides; Comprise a brake pull-rod and handsaw; It is characterized in that: a dismountable retaining sleeve is installed on the T-head of brake pull-rod, and described retaining sleeve comprises and has the parts that clamp T-head and the fixing device of handsaw, and handsaw can be pulled down from retaining sleeve.
The parts of above-mentioned clamping T-head can be to extend to take the shape of the letter U from the retaining sleeve body to coat the plate body of T-head, and are with the butterfly screw that the T-head of brake pull-rod is fastening between plate body and the retaining sleeve body.
The mode of said fixing handsaw can be to carry out the handle of retaining sleeve and handsaw fastening through the butterfly screw.
What the utility model insulated part adopted is ripe product---insulating bar, and the insulating bar convenient disassembly is widely used in a plurality of fields of electric line, and its method for using and points for attention are familiar with by operating personnel and are grasped.
Being connected of insulating bar and handsaw adopts butterfly screw and screw rod to realize.Butterfly screw hand is twisted can reach fastening effect, can learn at a glance.Instrument assembling adopts the butterfly screw fastening, and flexible and convenient operation is not destroyed the independent separately operating characteristic of handsaw, insulating bar.
The insulation trim saw can carry out trees pruning felling operation, thereby improve the line powering reliability under not power failure of circuit situation.The lengthening insulating bar that it adopts has reduced the operation that personnel climb trees, has promoted trees pruning operating personnel safety.
