Description
Technical field
The present invention relates to the service kit in a kind of power industry, particularly a kind of instrument for dismounting disconnector contact-finger.
Background technology
Disconnecting link generally uses in power industry, the Main Function of disconnecting link is when overhaul of the equipments or change operation power mode, realized disconnection or the connection of bus and secondary device by the folding controlling disconnecting link, when disconnecting link is in open mode, in transmission line, form obvious cut-off point.Fingertip is the important composition parts of disconnecting link, it comprises contact finger piece and spring, every two pieces of contact finger pieces form a pair fingertip, linking springs between two pieces of contact finger pieces in often pair of fingertip, in GW5 disconnector contact-finger, every block contact finger piece is provided with the bar-shaped trough of pendulum spring, the two ends of spring all bend in crotch shape, spring one end mounts by laterally taking the cross bar be placed on bar-shaped trough through after the bar-shaped trough in contact finger piece, and the other end of spring is also articulated on another contact finger piece corresponding with this contact finger piece by identical mode.
Disconnecting link is mainly arranged on outdoor use, and due to the impact by various factorss such as weather, the spring in disconnector contact-finger or contact finger piece often can be damaged because of corrosion, and this just needs often to change disconnector contact-finger parts, to ensure the normal use of disconnecting link.In the process changing disconnector contact-finger parts, because spring tension is comparatively large, operating personnel operates comparatively difficult, even also can come to harm because of undue force.In addition, in GW5 disconnector contact-finger, have multipair contact finger piece, install in fingertip process at new disconnecting link, about fingertip is installed and completely generally needed half an hour, installation effectiveness is low, and staff's working strength is large.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of handling safety, easy accessibility, can the dismantling device of quick-replaceable GW5 disconnector contact-finger sheet.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
The dismantling device of GW5 disconnector contact-finger, comprise and inserting in fingertip bar-shaped trough for provoking the slope expending section of spring between contact finger piece, one end of described slope expending section be provided with deviate from fingertip spring, for mounting the crotch of spring, the other end of slope expending section connects passive supporting section by inverted L shape linkage section, and the outer end arc transition of supporting section is connected with is convenient to hand-held handle; Described slope expending section, inverted L shape linkage section, supporting section and handle are a hard metal bar bending one-shot forming.
Further improvement of the present invention is: described supporting section is U-shaped structure.
Further improvement of the present invention is: be provided with bending angle between described slope expending section and inverted L shape linkage section, and the angle of bending angle is 120 ° ~ 180 °.
Further improvement of the present invention is: the shape of described handle is that class is rectangular-shaped, is provided with stressed angle between the arc transition section of handle and supporting section outer end, and the angle of stressed angle is 120 ° ~ 180 °.
Owing to have employed technique scheme, the technological progress that the present invention obtains is:
The present invention in use, slope expending section with crotch is inserted in the spring of contact finger piece bottom, now the strong point of supporting section is positioned on contact finger piece, pass through lever principle, press down handle gently, spring very strong for active force own between a pair contact finger piece can be pulled open further, the cross bar of linking springs on contact finger piece can be taken out, with the fingertip on disconnecting link for convenience detach, convenient and safe.When installing disconnector contact-finger sheet, with the crotch of slope expending section, spring being provoked, inserting cross bar, rapidly convenient.
The angle of the bending angle that slope expending section of the present invention and inverted L shape linkage section are formed is 120 ° ~ 180 °, and during use, the crotch of slope expending section more easily inserts spring, is provoked.
The stressed angle formed between handle of the present invention and supporting section is 120 ° ~ 180 °, and when using the handle urged forward of likeness in form rectangle, thumb can be stuck between stressed angle, thus more easily makes the crotch of slope expending section be inserted in spring.

Fig. 1 is structural representation of the present invention.
Wherein, 1, slope expending section, 2, bending angle, 3, inverted L shape linkage section, 4, supporting section, 5, stressed angle, 6, handle, 7, crotch.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details:
The dismantling device of GW5 disconnector contact-finger, its structural representation as shown in Figure 1, comprises slope expending section 1, inverted L shape linkage section 3, supporting section 4 and handle 6, and slope expending section 1, inverted L shape linkage section 3, supporting section 4 and handle 6 is a hard metal bar bending one-shot forming.Wherein, slope expending section 1 is for inserting and provoking the spring between contact finger piece, and one end of slope expending section 1 is provided with crotch 7, and crotch 7 deviates from fingertip spring and arranges, and crotch 7 is for mounting spring; The other end of slope expending section 1 connects supporting section 4 by inverted L shape linkage section 3, and the strong point of supporting section 4 is arranged on contact finger piece, and supporting section 4 plays a supportive role, and supporting section 4 is U-shaped structure; The outer end of supporting section 4 connects is convenient to hand-held handle 6, has arc transition section between supporting section 4 and handle 6.
Be provided with bending angle 2 between described slope expending section 1 and inverted L shape linkage section 3, the angle of bending angle 2 is 120 ° ~ 180 °.The angle of bending angle 2 is 175 ° in the present embodiment.
The shape of described handle 6 is that class is rectangular-shaped, is provided with stressed angle angle 5 between the arc transition section of handle 6 and supporting section 4 outer end, and stressed angle 5 angle is 120 ° ~ 180 °.The angle of stressed angle 5 is 165 ° in the present embodiment, when crotch 7 on slope expending section 1 starts the spring acted between contact finger piece, need the horizontal force of an insertion spring, therefore, operating personnel hold with a firm grip handle and thumb acts on stressed angle 5, when laterally promoting, the crotch 7 on slope expending section 1 can be made to be more prone to insert the spring between contact finger piece.
When changing disconnector contact-finger parts, crotch 7 in slope expending section 1 of the present invention is through the bar-shaped trough in the contact finger piece of disconnector contact-finger, enter into the spring between contact finger piece, supporting section 4 take contact finger piece as the strong point, pass through lever principle, light pressure handle 6 downwards, spring is provoked, and spring is not easily landing under the effect of crotch 7; Then take out for support spring and take the cross bar be placed on contact finger piece; Last release lever, falls spring after rise gently, and when spring tension is zero, fingertip of dismantling, changes disconnector contact-finger parts.
When carrying out disconnector contact-finger and installing, slope expending section 1 of the present invention is through the bar-shaped trough in contact finger piece, enter into the spring needing to install, supporting section 4 is the strong point with contact finger piece, by lever principle, and light pressure handle 6 downwards, spring is provoked, make the crotch of spring tip pass bar-shaped trough in contact finger piece, then cross bar is overlapped on contact finger piece through spring, finally take out the present invention.
