Description

Pruning device with worm gear structure
Technical field
The present invention relates to defeated, distribution wire operation maintenance field, specifically a kind of pruning device with worm gear structure.
Background technology
In electric line tour process, usually occur that trees branch and bamboo bar hinder, or even the situation of wound wire, so both affected the safe power supply of electric line, simultaneously also may affect the reliable power supply of power transmission and distribution, or even bringing the major safety risks such as mountain fire or person electric shock, must cut down cleaning this moment to trees branch and bamboo wood.At present, the cleaning of trees branch and bamboo wood is usually adopted felling tree bamboo and is pruned branch and realize, such secateurs one can't be cleared up the trees branch of far-end and eminence, make operation limited, general secateurs shearing is less in addition, can't clear up larger trees branch and bamboo wood, cause cleaning not thorough.
Summary of the invention
The invention provides the pruning device with worm gear structure, the cleaning that has solved trees branch and bamboo wood in the past is easily limited, can't accomplish the problem of thoroughly putting in order.
the present invention is that the technical solution problem is achieved through the following technical solutions: with the pruning device of worm gear structure, comprise cutting out section and running part, the quiet cutter head of described cutting out section and knife section, be provided with the edge of a knife that matches with knife section on quiet cutter head, described running part comprises worm screw, worm gear, the energy storage bar, ratchet, pull bar, described knife section is arranged on worm screw, the worm and wheel engagement, worm gear and the engagement of energy storage bar, energy storage bar and ratchet engagement, be socketed with energy-stored spring on described energy storage bar, and the energy storage bar is provided with lock pin, described ratchet is connected with pull bar.
The edge of a knife on quiet cutter head matches with knife section, forms clip, and this clip opens along with the motion of knife section or be closed; Running part is realized gathering and the release of energy, at first, by swinging pull bar, the motion of pull bar drives ratchet and rotates, and kinetic energy is sent to the energy storage bar, the energy storage bar is setting in motion and compressed energy-storage spring under the effect of ratchet, simultaneously, the energy storage bar drives worm gear and rotates, and worm gear correspondingly drives worm movement, knife section motion on worm screw, open clip; The continuous motion of pull bar, energy-stored spring is constantly compressed, until reach capacity, the engagement of ratchet disengaging at this moment and energy storage bar, this moment, energy storage pull bar and lock pin were in the percussion state, swing again along with pull bar, lock pin is pulled the trigger, energy-stored spring release pressure, energy storage bar under the effect of energy-stored spring, drive the worm gear reverse rotation, the worm gear drives worm screw is cooked axial return movement, closed clip, finally utilize the worm and gear principle to form huge shearing thrust at clip, reaches the purpose of cutting off branch, bamboo pole etc.; When the energy storage bar resetted, ratchet also meshed with the energy storage bar simultaneously again.
Further, the outside of described energy-stored spring is provided with sleeve, and the length of described sleeve is equal to or greater than the length of energy storage bar.Sleeve can be fixed the motion bodily form of energy-stored spring, simultaneously the working environment of energy-stored spring is played a protective role.
Further, described quiet cutter head is provided with cavity, and knife section and worm screw are positioned at this cavity.Knife section and worm screw can move back and forth in this cavity, realize opening and closure of clip, make total more reasonable.
Further, the edge of a knife on described quiet cutter head and the edge of a knife of knife section are all curved, and cave inward.When shearing, the edge of a knife on quiet cutter head and the edge of a knife of knife section are just in time embraced branch or bamboo pole, and shear effect is better like this.
Further, described pull bar is provided with return spring.Return spring has been arranged, while carrying out the eminence operation, pull bar of every swing, spring can reset pull bar, can reduce like this requirement of aid, needn't all by aid, pull bar be resetted at every turn.
Further, on pull bar, the end away from ratchet is provided with draw ring.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) the present invention is by design cutting out section and running part, running part is by the swing of pull bar, energy-stored spring is compressed to the limit then discharges, the energy storage bar under the effect of energy-stored spring, drives the worm gear reverse rotation, the worm gear drives worm screw is cooked axial return movement, closed clip, utilize the worm and gear principle to form huge shearing thrust at clip, and branch, bamboo pole etc. is easily cut off, can shear branch of far-end, eminence etc., thereby accomplish thorough cleaning.
(2) the present invention is easy to operate, is easy to realize, labour intensity and the reduction work that can alleviate staff's operation maintenance are dangerous, simultaneously lightweight, also are easy to carry.
