Fig. 1 is the structural representation of the Bird's Nest cleanout tool of the utility model first embodiment;

Fig. 2 shows Bird's Nest cleanout tool shown in Figure 1, and wherein, first jig arm and second jig arm of clamp are in clamped condition; And

Fig. 3 shows the structural representation according to the Bird's Nest cleanout tool of the utility model second embodiment.

Embodiment

With each embodiment the utility model is described below with reference to the accompanying drawings.

The utility model Bird's Nest cleanout tool comprises insulating bar and is supported in the clamp on insulating bar top that in the following embodiments, opening and clamping by drag-line of clamp controlled, to remove the Bird's Nest on the charged facility.

Fig. 1 is the structural representation of the Bird's Nest cleanout tool of the utility model first embodiment, and Fig. 2 shows Bird's Nest cleanout tool shown in Figure 1, and wherein, clamp shown in Figure 1 is in open configuration, and clamp shown in Figure 2 is in clamped condition.In conjunction with seeing figures.1.and.2, Bird's Nest cleanout tool 10 comprises: the drag-line 140 of insulating bar 120, the clamp 110 that is installed on insulating bar 120 tops and control clamp.Below each parts is described and discusses.

Clamp 110 has first jig arm 111 and second jig arm 113 of pivot joint.Effective clamping length L of first jig arm and second jig arm is set in about 400mm, so that this Bird's Nest cleanout tool is suitable for the Bird's Nest of most of type, has versatility.Certainly, if when only needing to remove the Bird's Nest of certain or certain several size, effectively clamping length can be revised, for example between 200～410mm.

First jig arm 111 is for being fixedly connected on the fixing clamp arm of insulating bar 120.This is fixedly connected can be dismountable connection, also can be non-removable connection.In addition, can form anti-slop serrations 111A on this first jig arm, so that the Bird's Nest on switch and the house dog is operated on the coupled columns.

Be connected with drag-line 140 on second jig arm, this second jig arm 113 is opened with respect to first jig arm 111 under the effect of cable pull power and/or spring tightening force or is clamped, and promptly this second jig arm is the activity jig arm.In the present embodiment, when drag-line did not apply tightening force, first jig arm and second jig arm were in open state under the effect of spring tension.At this, the clamp in the present embodiment is called " often driving clamp ".

This first jig arm 111 can be formed by drift bolt or rivet connection by two sheet materials of space, and the material of this sheet material can be an epoxy glass laminate, so that electric insulation and structural strength to be provided.

Drag-line 140 must be a for example nylon rope of insulation ropes, also can be the rope of certain mechanical strength of having of other and dielectric strength.This drag-line 140 enters insulating bar 120 inside, and is connected to the afterburning support 130 of insulating bar lower end.Drag-line 140 is arranged to enter insulating bar benefits, drag-line can not be subjected to external interference or disturb extraneous member like this, with handled easily.

Afterburning support 130 comprises cantilever 131 that is fixed on the insulating bar and the afterburning handle 133 that is articulated in cantilever 131, this reinforcing handle 133 runs through insulating bar 120, the drag-line that is arranged in insulating bar like this can be fixed on the afterburning handle 133, comes afterburning by afterburning handle.This reinforcing support 130 can be made by aluminum alloy materials, to utilize the characteristic of its light-high-strength.Can certainly not establish afterburning support 130, and directly use hand control drag-line 140.

Have roller bearing 121 in insulating bar inside, this roller bearing provides break-in for drag-line 130, and reduces the friction between drag-line and the insulating bar, increases the useful life of drag-line 130.This roller bearing can have a plurality of, and so that repeatedly break-in to be provided, like this, drag-line can transmit pulling force and have less frictional resistance in the insulating bar of bending.And crooked insulating bar is helpful for the Bird's Nest that removes the position complexity.In addition,, has protective sleeve 125, to prevent insulating bar 120 tops cracking on the top of insulating bar 120.In the bottom of insulating bar 120, have rubber sleeve 123, non-slip for the operator grips.

Fig. 3 shows the structural representation according to the Bird's Nest cleanout tool of the utility model second embodiment.The Bird's Nest cleanout tool 20 of present embodiment comprises insulating bar 220, is installed in the clamp 210 of insulating bar 220 ends and the drag-line 240 of operation clamp 210.When entering insulating bar 220, passes through this drag-line 240 roller bearing 221 break-ins.The present embodiment and the first embodiment difference are: in the present embodiment, second jig arm 213 is fixedly connected on insulating bar 220 by connecting portion, is fixing clamp arm, and first jig arm then is the activity jig arm.First jig arm 211 and second jig arm 213 are articulated across, like this, and under the tightening force effect of back-moving spring 215, clamp usually remains in clamped condition, open under the tension of drag-line 240, therefore, the clamp in the present embodiment is called " normally closed clamp " again.

By above description as can be seen, when the Bird's Nest cleanout tool that utilizes first embodiment was removed Bird's Nest, Bird's Nest was between first jig arm and second jig arm, and Bird's Nest is clamped and remove, and this instrument is applicable to the Bird's Nest that branch is built.When the Bird's Nest cleanout tool that utilizes second embodiment is removed Bird's Nest, first jig arm and second jig arm are disclosed in the Bird's Nest, first jig arm and second jig arm are opened afterwards, and Bird's Nest is blocked and removes by the outward flange of first jig arm and second jig arm, and this instrument is applicable to the Bird's Nest that the grass wadding waits material to build.

Can expect that some features among the above-mentioned embodiment can be used for another embodiment, as long as these features are not conflicting.

The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
