Description
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 affect the safe power supply of electric line, also may affect the reliable power supply of power transmission and distribution simultaneously, or even bring the major safety risks such as mountain fire or person electric shock, now must carry out felling cleaning to trees branch and bamboo wood.At present, the cleaning of trees branch and bamboo wood usually adopts felling tree bamboo and prunes branch and realizes, such secateurs one cannot be cleared up the trees branch of far-end and eminence, make operation limited, secateurs shearing general is in addition less, larger trees branch and bamboo wood cannot be cleared up, cause cleaning not thorough.
Summary of the invention
The invention provides the pruning device with worm gear structure, the cleaning solving trees branch and bamboo wood is in the past easily limited, cannot accomplish the problem thoroughly put in order.
The present invention is that 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, described cutting out section comprises quiet cutter head and cutting blade, quiet cutter head is provided with the edge of a knife matched with cutting blade, described running part comprises worm screw, worm gear, energy storage bar, ratchet, pull bar, described cutting blade is arranged on worm screw, worm and wheel engages, worm gear engages with energy storage bar, energy storage bar engages with ratchet, described energy storage bar is socketed with energy-stored spring, and 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 cutting blade, forms clip, and this clip opens along with the motion of cutting blade or closes; Running part realizes gathering and the release of energy, first, by swinging pull bar, the motion of pull bar drives pawl wheel, and kinetic energy is sent to energy storage bar, energy storage bar setting in motion compressed energy-storage spring under the effect of ratchet, meanwhile, energy storage bar drives worm gear wheel, and worm gear correspondingly drives worm movement, cutting blade motion on worm screw, makes clip open; The continuous motion of pull bar, energy-stored spring is constantly compressed, until reach capacity, now ratchet departs from the engagement with energy storage bar, now energy storage pull bar and lock pin are in cock, along with the swing again of pull bar, lock pin is pulled the trigger, energy-stored spring release pressure, energy storage bar, under the effect of energy-stored spring, drives worm gear to reversely rotate, worm gear drives worm screw to do axial return movement, closed clip, finally utilizes worm and gear principle to form huge shearing thrust at clip, reaches the object of cutting off branch, bamboo pole etc.; When energy storage bar resets, ratchet also engages with 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, plays a protective role to the working environment of energy-stored spring simultaneously.
Further, described quiet cutter head is provided with cavity, and cutting blade and worm screw are positioned at this cavity.Cutting blade and worm screw can move back and forth in this cavity, realize opening with closed of clip, make total more reasonable.
Further, the edge of a knife on described quiet cutter head and the edge of a knife of cutting blade all curved, and to cave inward.When shearing, the edge of a knife on quiet cutter head and the edge of a knife of cutting blade just in time embrace branch or bamboo pole, and such shear effect is better.
Further, described pull bar is provided with return spring.Had return spring, when carrying out eminence operation, often swing a pull bar, pull bar can reset by spring, can reduce the requirement of aid like this, need not all be resetted by pull bar by aid at every turn.
Further, the one end away from ratchet on pull bar 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 discharge, energy storage bar, under the effect of energy-stored spring, drives worm gear to reversely rotate, worm gear drives worm screw to do axial return movement, closed clip, utilizes worm and gear principle to form huge shearing thrust at clip, branch, bamboo pole etc. is easily cut off, can shear the branch etc. of far-end, eminence, thus accomplish thorough cleaning.
(2) the present invention is easy to operate, is easy to realize, and labour intensity and the reduction work that can alleviate staff's operation maintenance are dangerous, simultaneously lightweight, are also easy to carry.
