Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
A kind of transmission line protective device described in the utility model comprises the location suspending hammer, disconnector pedestal 2 and steel strand wires clamping plate 1,
Described steel strand wires clamping plate below is fixed with hook;
Described disconnector base bottom has and hangs through hole 9, and the translation occlusion structure that cooperates with steel strand wires clamping plate 1 is arranged at disconnector pedestal 2 tops, and the disconnector pedestal also comprises and is used for the electric pole syndeton that is connected with electric pole;
Described location suspending hammer comprises suspending hammer body and the suspending hammer arm 5 that is connected with the suspending hammer body, and described suspending hammer arm top has the suspended structure that cooperates with described hook.
At normal operating condition, steel strand wires are by the clamping of steel strand wires clamping plate, the steel strand wires clamping plate are placed on above the disconnector pedestal, be interlocked by the translation occlusion structure with the disconnector pedestal, described translation occlusion structure guarantees at steel strand wires clamping plate 1 and disconnector pedestal 2 relative displacement not to take place in the horizontal direction.Optical cable passes between steel strand wires clamping plate and the disconnector pedestal or side side, and the suspending hammer arm of location suspending hammer passes the suspension through hole of disconnector bottom, is suspended on by the suspended structure that is positioned at suspending hammer arm top on the hook of steel strand wires clamping plate below.Steel strand wires clamping plate, disconnector pedestal and location suspending hammer are connected by the way to be done as a wholely, fixedlys connected with electric pole by the electric pole syndeton that is positioned on the disconnector pedestal.The suspending hammer gravitate keeps vertical direction with electric pole automatically.
In when, geologic hazard or other reasons taking place causing electric pole to tilt when, because the suspending hammer activity is suspended on the hook, gravitate, the suspending hammer arm keeps vertical direction.Steel strand wires clamping plate and disconnector pedestal are by the interlock of translation occlusion structure, electric pole drives disconnector pedestal and steel strand wires clamping plate integral inclination, cause the hook position angle under the steel strand wires clamping plate all to change, when the electric pole angle of inclination acquired a certain degree, suspended structure broke away from hook.Be connected with the disconnector pedestal by occlusion structure owing to the steel strand wires clamping plate before, guarantee that the steel strand wires clamping plate can not move downward, and the movement tendency that the steel strand wires clamping plate make progress is subjected to suspending hammer to pull the hook restriction, in case hook breaks away from, the tension of steel strand that the steel strand wires clamping plate are out of shape pulls, at once break away from the disconnector pedestal, thereby steel strand wires are separated with electric pole, avoided steel strand wires to be toppled over electric pole and broken.
It is L shaped that described hook is preferably the right angle.The stressed maintenance of vertical direction was stablized when L shaped hook kept normal condition at electric pole, and suspended structure is easy to break away from from the open end of L shaped hook when electric pole tilts.
Described suspended structure is preferably the clutch shaft bearing roller 11 that is fixed on suspending hammer arm top.Be difficult for corrosion takes place between bearing roller and the hook, and when electric pole tilts, be easy to break away from hook.
For avoiding hook and suspended structure being in for a long time under the field environment because corrosion is difficult to break away from, guarantee the physical strength of hook and suspended structure simultaneously, link up with and suspended structure preferably to adopt stainless steel be manufactured materials.
The steel strand wires clamping plate are used for the clamping steel strand wires, and the utility model provides a kind of embodiment, and the steel strand wires clamping plate comprise clamping plate body and steel strand wires fixed head, and described steel strand wires fixed head 10 is connected with the clamping plate body by bolt.Unclamp bolt during use earlier, steel strand wires are clamped on the clamping plate body with the steel strand wires fixed head, again bolt is tightened.
Fig. 1 to Fig. 2 illustrates a kind of embodiment of the utility model, and described steel strand wires clamping plate and disconnector pedestal are L shaped flap, and there is outwards outstanding biteplate at steel strand wires clamping plate top board edge; Described disconnector pedestal top side wall has the rectangular depression 8 identical with described biteplate width.Disconnector pedestal sidewall middle part is equipped with bolt through hole 4 is installed, and is used for being connected with electric pole, and the steel strand wires clamping plate comprise that clamping plate body and steel strand wires fixed head are used for steel strand wires are gripped.The suspended structure at suspending hammer arm top is the clutch shaft bearing roller, described hook is L shaped, the clutch shaft bearing roller widths equates with it or is approaching, be placed on the L shaped hook during normal the use, when electric pole is toppled over the position that drives disconnector pedestal and hook and angle when being offset to a certain degree, the landing from the L shaped hook of clutch shaft bearing roller, the steel strand wires of distortion pull the steel strand wires clamping plate from the disconnector pedestal, thus the situation of having avoided steel strand wires to be torn.
Preferably, described suspending hammer arm middle part is fixedly connected with second bearing roller 12, the second bearing roller upper surface applying disconnector pedestal, 2 bottoms, can be along disconnector pedestal 2 bottoms slide among a small circle, second bearing roller is fixed the hanging position of suspended structure and hook, has strengthened the location suspending hammer and has hung connection stability with hook; And suspension through hole 9 is blocked in use, avoids open-air toy or insect to enter; Simultaneously when electric pole tilted, second bearing roller 12 played guide effect, made that the steel strand wires clamping plate are easier to break away from from the disconnector pedestal.
Adopt transmission line protective device described in the utility model, change the fixed form of present steel strand wires and electric pole, make it that steel wire, optical cable can break away from it when electric pole is toppled over, do not broken with the protection communications optical cable.Because the utility model deft design, simple in structure, so the device expense is comparatively cheap.In the few situation of increase expense, saved and speedily carried out rescue work and maintenance cost.
Previously described is each preferred embodiment of the present utility model; preferred implementation in each preferred embodiment is if not obviously contradictory or be prerequisite with a certain preferred implementation; each preferred implementation stack combinations is arbitrarily used; concrete parameter among described embodiment and the embodiment only is the utility model proof procedure for clear statement utility model inventor; be not in order to limit scope of patent protection of the present utility model; scope of patent protection of the present utility model still is as the criterion with its claims; the equivalent structure that every utilization instructions of the present utility model and accompanying drawing content are done changes, and in like manner all should be included in the protection domain of the present utility model.
