Abstract
The invention discloses a front clamp of a decomposition type ground potential replacement clamp. The front clamp is a wing type clamp, wherein square opening grooves are formed at two ends of two wings of the wing type clamp; positioning through holes, which are communicated with each other, are formed in upper and lower groove edges of the opening grooves of the two wings of the wing type clamp; a locking pin is arranged on the wing type clamp; the locking pin is connected to the positioning through holes in the two wings of the wing type clamp in a movable manner; the locking pin is positioned at the groove edges of the opening grooves of the two wings by using a positioning piece; a through hole into which the locking pin can be inserted is formed in an insulating pulling plate; and when the insulating pulling plate is inserted into the opening grooves of the two wings of the front clamp, the positioning piece is pulled out, the locking pin freely falls down under the action of self gravity, the locking motion of the locking pin is finished by adjusting the position of the insulating pulling plate, and the insulating pulling plate and the front clamp are locked. The front clamp has the advantages that: by using a decomposition installation method, the clamp is detachable; the front clamp can flexibly pass through a double-split conductor, and has a reliable function of a locking device; and the weight of the clamp during installation is reduced.
Description
Technical field
The present invention relates to the front card of a kind of discrete-type earth potential replacement fixture, particularly discrete-type earth potential replacement fixture.
Background technology
Existing earth potential replacement fixture, because the physical property of fixture structure has determined that jig can only adopt integral installation, after namely in advance the whole series card peace being assembled, by a plurality of electricians, together jig is lifted on insulator string and is installed again, this mounting means, because a whole set of jig overall weight is large, also need that jig is lifted to higher position installs simultaneously, therefore installation difficulty is large, operating personnel's labour intensity is large, the danger of operation is high, inefficiency, and cannot complete the charged installation of wiring on the same tower circuit.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and provide a kind of, overcome jig a difficult problem is installed, reduce the front card of the discrete-type earth potential replacement fixture of labour intensity.
A kind of front card of discrete-type earth potential replacement fixture, described front card is wing card, its structural feature is: the both ends of wing card two flanks are square open slot, the opening direction of described open slot parallels with the plane extension direction of wing card two flanks, on two trough rims up and down of wing card two flank open slots, offer the positioning through hole of mutual perforation, on wing card, be also provided with a lockweight, this lockweight is movably connected on the positioning through hole place on wing card two flanks, before insulation pulling plate snaps in these front card two flank open slots, described lockweight utilizes keeper to be located trough rim place on two flank open slots, on insulation pulling plate, be provided with the through hole that can insert lockweight, while blocking two flank open slots before insulation pulling plate inserts, pull out keeper, lockweight freely falls under the effect of deadweight, by adjusting the position of insulation board, lockweight is completed latch action, pin insulation pulling plate and front card.
The front card of this structure, in use, due to self-locking gear, therefore can realize with the decomposition of rear card, insulation pulling plate and installing, when mounted, front card can independently be arranged on assigned address or pass through be arranged on by insulating bar, operate after lower Square wire before the lockweight of card front card is stuck in to wire regulates on winning in succession and complete locking.Its concrete operations are for to be entered insulation pulling plate by action bars by an electrician along the open slot on front card two flanks, operation insulation pulling plate is adjusted to the length needing, No. two electrician utilizes insulating bar lockweight freely to be fallen the keeper on front card two flanks, adjusts insulation pulling plate to lockweight and completes locking.With the method, complete the installation of left and right insulation pulling plate.Card after then installing again.Therefore adopt front card of the present invention to overcome the various shortcomings that need to adopt integral installation to bring, greatly reduce operating personnel's labour intensity.
The mode that lockweight is movably connected on wing card two flanks is: along lockweight axially offer the logical heart slotted hole of a section, in logical heart slotted hole, be provided with and lockweight can be stuck in to the latch on wing card.
During use, utilize latch to pass passing through on lockweight, then lockweight is filled in the through hole of trough rim on wing card two flanks, and utilized latch to be stuck on wing card.
Described flexible connection can also be that the flexible things such as direct sharp rope hang on lockweight on wing card two flanks.
Described keeper is movably connected on front card.
The flexible connection of described keeper or for hanging on front card, or for being articulated with on front card.
Described keeper or be spring leaf, or be common blocks etc.
In sum, the present invention's following advantage compared to existing technology:
The front card of discrete-type earth potential replacement fixture of the present invention has cracked the difficult problem that this type of jig integral installation greatly cannot earth potential live be installed because of weight.Adopt and decompose the method for installing, jig is detachable, front card can pass through flexibly double bundle conductor, have the function of reliable locking device, reduced weight when jig is installed, this method both can be simplified operation procedure, alleviated operating personnel's labour intensity, reduced the danger of live line working, increase work efficiency, greatly improved again power supply reliability and maintenance benefit.And provide a kind of, can under charged condition, kit all parts be arranged on live wire branch's decomposition, and then each parts are assembled to this jig
