Description
Technical field
The present invention relates to transmission overhead line field, particularly relate to a kind of clamping device for cutting down, pruning trees in transmission overhead line passage.
Background technology
Transmission line of electricity carries the conveying of user's electric energy, it is the lifeline of electric power enterprise, electric power line pole tower is erected at field usually, and in line channel, the trees of plantation are the maximum potential safety hazards of line security stable operation, and process screen of trees just can guarantee the safe operation of circuit in time.According to " electric power safety working regulation " power line portion pertinent regulations, at present the method for process screen of trees has: one be fall trees, two are pollards.Prior art has usually for the treatment of the instrument of screen of trees: averruncator, Gao Zhiju, chain saw, handsaw and chopper etc.The branch cut off is uncontrollable in drop event, easily causes infringement safe distance to cause the accident, has a strong impact on the safety of transmission line of electricity, or jeopardize below personnel and property safety.
When trees and high-voltage conducting wires distance meet safe distance, when felling or pruning trees, for controlling the toppling direction of trees (branch), current use rope or tree hook are fixed on branch, ground staff pulls rope or tree hook, the object controlling trees (branch) toppling direction to reach, prevent trees touching wire from having an accident.But stationary rope needs staff to climb trees binding, to waste time and energy and potential safety hazard is comparatively large, sometimes cannot bundle because trees are tiny and branch is tender.Time tree is hooked in and controls branch or trunk, because tree hook opening is less, branch is pliable and tough, often there is the danger of breaking off relations, easily cause the out of control security risk of trees.Above instrument, because not controlling the toppling direction of trees quickly and safely, easily causes potential safety hazard, lacks special instrument and increases work efficiency and safety, can not meet need of production.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of clamping device, reduce felling, prune the security risk that critical trees bring, not only guarantee the safety of staff, the safe and stable operation of circuit can also be guaranteed, avoid the generation of the severe accidents such as line tripping.
In order to solve the problems of the technologies described above, the invention provides a kind of clamping device, for clamping, fix and pull held object, comprise the first operation hook and the second operation hook that are hinged, described first operation hook comprises the first coupler body of front end and the first driving rod of rear end, and described second operation hook comprises the second coupler body of front end and the second driving rod of rear end; Described first driving rod is hinged with first connecting rod, and described second driving rod is hinged with second connecting rod; Described first connecting rod and second connecting rod are hinged and make described first driving rod, the second driving rod, first connecting rod and second connecting rod form quadrangle.
As preferably, described first connecting rod is connected with insulated tension pole away from one end of described first driving rod.
As preferably, described first coupler body and the second coupler body have the first relative arc clamping face and the second arc clamping face respectively.
As preferably, described first arc clamping face and the second arc clamping face have sawtooth.
As preferably, described first driving rod offers the first installing hole that at least one and described first connecting rod are hinged; Described second driving rod offers the second installing hole that at least one and described second connecting rod are hinged.
As preferably, described head rod is provided with for auxiliary described gripping apparatus grips, fixing and pull the draw ring of held object.
Compared with prior art, the beneficial effect of clamping device of the present invention is: by being with serrate first operation hook and the second operation hook, and with first connecting rod and second connecting rod articulated structure flexibly, the trees firmly promptly will cut down, pruned, greatly reduce tree hook slippage number of times, realize cutting down fast, pruning critical trees, reduce the security risk of climbing trees personnel.

Embodiment
Be described in further detail below in conjunction with the clamping device of the drawings and specific embodiments to embodiments of the invention, but not as a limitation of the invention.
Fig. 1 is the overall structure schematic diagram of the clamping device of embodiments of the invention; Fig. 2 is the structural representation of the first operation hook of the clamping device of embodiments of the invention; Fig. 3 is the structural representation of the second operation hook of the clamping device of embodiments of the invention; Fig. 4 is the using state structural representation of the clamping device of embodiments of the invention.As shown in the figure, the clamping device of embodiments of the invention, for clamping, fix and pull held object, held object can make trees etc., comprise the first operation hook 1 and the second operation hook 2 be hinged, first driving rod 12, second of the first coupler body 11 and rear end that the first operation hook 1 comprises front end operates hook 2 and comprises the second coupler body 21 of front end and the second driving rod 22 of rear end; First driving rod 12 is hinged with first connecting rod 3, and the second driving rod 22 is hinged with second connecting rod 4; First connecting rod 3 and second connecting rod 4 are hinged and make described first driving rod 11, second driving rod 12, first connecting rod 3 and second connecting rod 4 form quadrangle.During use, by pulling first connecting rod 3, lever principle is utilized to make the first coupler body 11 and the second coupler body 12 lock to clamp the gripped objects such as trees.The clamping device of embodiments of the invention, by the first operation hook 1 and the second operation hook 2, and with first connecting rod 3 and second connecting rod 4 articulated structure flexibly, the trees firmly promptly will cut down, pruned, greatly reduce tree hook slippage number of times, realize cutting down fast, pruning critical trees, reduce the security risk of climbing trees personnel.
Improve as one, the first connecting rod 3 of the clamping device of embodiments of the invention is connected with insulated tension pole 5 away from one end of the first driving rod 12.Practical operation, because transmission overhead line operation belongs to altitude hot-line operation, can operate eminence object by arranging insulated tension pole 5, safe and convenient easily.
As further improvement, the first coupler body 11 and second coupler body 21 of the clamping device of embodiments of the invention have the first relative arc clamping face 110 and the second arc clamping face 210 of arc respectively.As the preferred version of the present embodiment, the first arc clamping face 110 and the second arc clamping face 210 have sawtooth.As shown in Figure 1, the first arc clamping face 110 has the first sawtooth 111, second arc clamping face 210 and has the second sawtooth 211.Such vibrational power flow, make serrate first arc clamping face 110 and the second arc clamping face 210 of the clamping device band of embodiments of the invention, on the one hand with the form fit of trees, greatly increase with the frictional force of trees on the other hand, contribute to firmly firmly grasping trees, further enhance steadiness, save labor simultaneously, be beneficial to operation.
