Core of the present invention is to provide a kind of anti-slip grounding wire device, and this equipment safety is good, and install convenient.Another core of the present invention is to provide a kind of power equipment comprising above-mentioned anti-slip grounding wire device.
Please refer to Fig. 1 to Fig. 5, Fig. 1 is the axonometric drawing of conductor end chuck in the specific embodiment of grounding wire device provided by the present invention; Fig. 2 is the front view of conductor end chuck in the specific embodiment of grounding wire device provided by the present invention; Fig. 3 is the axonometric drawing of action bars in the specific embodiment of grounding wire device provided by the present invention; Fig. 4 is the top view of action bars in the specific embodiment of grounding wire device provided by the present invention; Fig. 5 is another axonometric drawing of action bars in the specific embodiment of grounding wire device provided by the present invention.
The anti-slip grounding wire device of one provided by the present invention, is mainly used on power equipment, when carrying out the situation such as keeping in repair to power equipment, is connected to ground by a certain circuit of conductor on circuit.Anti-skid grounding wire device mainly comprises conductor end chuck 1, earth terminal connector and action bars on structure composition.Wherein, conductor end chuck 1, for clamping conductor, mainly comprises chuck upper plate 11 and chuck lower plate 12, and chuck upper plate 11 and chuck lower plate 12 are clamped by grip member 13.Certain chuck upper plate 11 and the clamping mode of chuck lower plate 12 are not limited to above-mentionedly asks condition.Several nails 14 are arranged in the longitudinal hole of chuck upper plate 11 with longitudinal movement, and the upper end of nail 14 is provided with the screens portion for preventing nail 14 from coming off; Conductor end chuck 1 is also connected with earth terminal connector.Action bars is for controlling the degree of tightness of conductor end chuck 1, and action bars is connected with conductor end chuck 1.
It should be noted that, above-mentioned longitudinal direction refers to the direction that chuck upper plate 11 clamps mutually with chuck lower plate 12, is the vertical direction in Fig. 2.When chuck upper plate 11 and chuck lower plate 12 clamp, the nail 14 being arranged in longitudinal hole is understood some and is squeezed and vertically moves.
It should be noted that, the mode of above-mentioned conductor end chuck 1 gripping conductor has a variety of, and the present embodiment mainly illustrates the mode that with the addition of nail 14 on chuck upper plate 11.The number of above-mentioned nail 14 is several, comprise one, two, three or more.Main Function due to nail 14 carries out spacing in the horizontal to conductor, so number is more within the specific limits, setting is closeer, more easily makes fixing the stablizing of conductor.
The anti-slip grounding wire mounting that the present embodiment provides is set up the nail 14 being provided with and can vertically moving, and the screens portion of nail 14 makes nail 14 be suspended on chuck upper plate 11, can not skid off from longitudinal hole.In use, the opening degree of chuck upper plate 11 and chuck lower plate 12 is transferred to maximum, nail 14 is suspended in longitudinal hole naturally, by the clamping position alignment conductor of chuck upper plate 11 and chuck lower plate 12 or busbar, and make chuck upper plate 11 and chuck lower plate 12 clamping by action bars, the nail 14 contacted with conductor or busbar retracts to above chuck upper plate 11 due to squeezing action, nature suspension status is still kept owing to not being squeezed in the nail 14 of conductor or bus side, because longitudinal hole limits the transverse shifting of nail 14, so nail 14 also forms the restriction of transverse shifting to conductor and bus, achieve the object preventing chuck and conductor or bus slippage.
In order to make the movement of nail 14 in longitudinal hole smooth and easy and ensure clamping position stability, longitudinal hole can be set to the taper hole with tapering, in one particular embodiment of the present invention, the aperture of the upper end hole of taper hole is greater than the aperture of lower stomidium, nail 14 is for having the nail of tapering, and the large-diameter end of nail 14 is arranged at upper end hole.In the present embodiment, nail 14 has tapering, be then free to mobile in the longitudinal hole equally with tapering, but the tapering of the two ensure that nail 14 can not skid off longitudinal hole.
That mentions in above-described embodiment realizes horizontal location by nail 14 pairs of conductors or busbar, conductor or busbar is completely fixed, although nail 14 is undertaken spacing by longitudinal hole in the horizontal, but does not still position in nail 14 lower end.In one particular embodiment of the present invention, can be fixed nail 14 in the lower end of nail 14.Such as, limited impression can be set in chuck lower plate 12, for when chuck upper plate 11 and chuck lower plate 12 clamp, make the lower end of nail 14 enter above-mentioned limited impression, thus limit moving radially of nail 14, namely transverse shifting.Particularly, limited impression and nail 14 position are corresponding up and down setting.
By arranging the limited impression corresponding with longitudinal hole in chuck lower plate 12, being formed the laterally fixing reinforcing of nail 14, making fixing of conductor or busbar more reliable.
On the basis of any one embodiment above-mentioned, be introduced for the structure of action bars and operation format, action bars mainly comprises swingle and sleeve 2, and swingle is the rod member for being rotated adjustment conductor end chuck 1 clamping degree by self, and swingle is connected with conductor end chuck 1.Sleeve 2 is fixedly connected with swingle.In addition, sleeve 2 is also connected with the revolving part of clockwise and anticlockwise motor 3, exports band moving sleeve 2 and rotates, and then the swingle be connected with sleeve 2 is rotated, reach the object controlling conductor end chuck 1 and clamp and unclamp by the rotation of clockwise and anticlockwise motor 3.In the present embodiment, adopt the motor with rotating, device can be made freely to control conductor end chuck 1 and be connected with the degree of tightness of conductor.
On the basis of above-described embodiment, in order to the operational stability of intensifier, sleeve 2 arranges the handheld tube 22 of empty set, there is no the fixing of circumference between handheld tube 22 with sleeve 2 or be connected, when sleeve 2 circumference is rotated, operating personnel can carry out position by the position adjusting handheld tube 22 to device and move.In addition, in order to ensure safety operation, handheld tube 22 should be set to isolation material handheld tube.
For the mode that action bars in the various embodiments described above is fixedly connected with sleeve 2, in an embodiment provided by the present invention, one end for connecting swingle on sleeve 2 is provided with mounting cylinder 21, the end of mounting cylinder 21 is provided with the axial gap for increasing radial contraction scope, and end is provided with can the cuff 23 of degree of tightness.Need it is to be noted that in the present embodiment, the axial gap of mounting cylinder 21 one end is interpreted as the gap in the axial direction with extension, and this gap might not be parallel to the axis of mounting cylinder 21.
Optionally, cuff 23 is dismountable cuff, cuff 23 is provided with for regulating cuff 23 to open or the handle 24 of banding, handle 24 by the mode of buckle by cuff 23 banding.Optionally, above-mentioned cuff 23 can also to carry out buckle by other structures or mode, anyly can the clip of folding all should belong in the scope that the present invention protects.
