Abstract
The invention discloses a fixing device of a rear clamp of a wing-shaped clamp. The fixing device comprises a Y-shaped clamping part and a bridging part, wherein the bridging part comprises two locking plates and two bolts, the two locking plates are oppositely arranged in parallel, and the two bolts cross the two locking plates in parallel and are in locking connection with the two locking plates by matching with nuts; one end of the Y-shaped clamping part is hinged on the bridging part through one of the two bolts, the other end of the Y-shaped clamping part is clamped in a clamping slot of the rear clamp of the wing-shaped clamp, and the other bolt of the bridging part is used for connecting a cross arm side. The fixing device of the rear clamp of the wing-shaped clamp has the advantages that connection between the rear clamp of the wing-shaped clamp and the cross arm side is achieved, the connection is uniform in stress, safe and reliable, and the safety and operation efficiency of hot-line replacement of a single strain insulator string are improved.
Description
Technical field
The present invention relates to clamp fixation device after a kind of wing type clamp apparatus.
Background technology
When 110kV-220kV line live-line work, change shaft tower strain insulator list insulator string and usually adopt wing type clamp apparatus.In concrete practice, current each electric company is when carrying out charged for replacement list string strain insulator string, there is no and adopt special fixing device to be fixed card after wing type clamp apparatus, following two kinds of modes are in most cases adopted to be fixed card after wing type clamp apparatus: to please refer to Fig. 1, a kind of is utilize card draw-in groove 200 after nut 101 clamping on cross-arm on original U-shaped ring 100 bolt, using the nut 101 on bolt as after fasten stress point, this fixed form often can cause nut cannot stick in rear card draw-in groove because bolt is too short, after causing wing type clamp apparatus, card cannot be fixed; Please refer to Fig. 2, another kind wears bolt again on the original U-shaped ring 100 of cross-arm side, be fixed in card draw-in groove 200 after the nut 102 of this bolt is sticked into wing type clamp apparatus, but adopt the bolt strained rear easy appearance of this kind of fixed form to bend even to fracture, there is certain potential safety hazard, and not easily install.As long as the fixing point blocked after wing type clamp apparatus in theory just can ensure that a whole set of wing type clamp apparatus is stressed safe and reliable on the axis of insulator string, therefore original fixing point can be shifted out from the original U-shaped ring of cross-arm side, fasten on the axis of insulator string after ensureing wing type clamp apparatus.
Summary of the invention
The invention provides clamp fixation device after a kind of wing type clamp apparatus, which overcome the deficiencies in the prior art described in background technology.
The technical solution adopted for the present invention to solve the technical problems is:
Clamp fixation device after a kind of wing type clamp apparatus, it comprises Y type card division and bridge part, described bridge part comprises interlocking plate and the two parallel bolts be across between this two interlockings plate of two parallel opposed, this two bolt by with nut screw connection interlocking in two interlocking plates, one bolted splice is passed through in bridge part in one end of described Y type card division, the other end be used for wing type clamp apparatus after the draw-in groove clamping that blocks, another bolt of described bridge part is used for being connected with cross-arm side.
Among one embodiment: described cross-arm side is connected with a U-shaped ring, described bridge part is connected on U-shaped ring by another described bolt lock.
The technical program is compared with background technology, and its tool has the following advantages:
By fastening behind the Y type card division of fixture and wing type clamp apparatus, bridge part and cross-arm side interlocking, achieve the connection of card and cross-arm side after wing type clamp apparatus, it connects uniform force, safe and reliable, improves fail safe and an operating efficiency that band point changes single string strain insulator string simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
A kind of fixed form schematic diagram that Fig. 1 blocks after depicting the existing wing type clamp apparatus described in background technology.
The another kind of fixed form schematic diagram that Fig. 2 blocks after depicting the existing wing type clamp apparatus described in background technology.
Fig. 3 depicts the three-dimensional structure diagram of clamp fixation device after a kind of wing type clamp apparatus of the present invention.
Fig. 4 depicts the connection diagram of clamp fixation device and wing type clamp apparatus after wing type clamp apparatus.
Embodiment
Please refer to Fig. 3, clamp fixation device after a kind of wing type clamp apparatus, it comprises Y type card division 1 and bridge part 2, described bridge part 2 comprises interlocking plate 21 and the two parallel bolts 22 be across between this two interlockings plate 21 of two parallel opposed, this two bolt 22 by with nut screw connection interlocking in two interlocking plates 21, one end of described Y type card division 1 is articulated with bridge part 2 by one bolt 221, the other end be used for wing type clamp apparatus after draw-in groove 200 clamping that blocks, another bolt 222 of described bridge part 2 is for being connected with cross-arm side.
Described cross-arm side is connected with a U-shaped ring 100, and described bridge part 2 passes through another described bolt 222 interlocking on U-shaped ring 100.
When this fixture is installed, in the draw-in groove 200 blocked after one end (sheepshead end) of the Y type card division 1 of fixture is connected in wing type clamp apparatus, another bolt 222 of bridge part 2 is opened, the U-shaped ring 100 of cross-arm side is connected with bridge part 2 snap close by this another bolt 222, since then, wing type clamp apparatus and cross-arm side couple together by fixture.
The above, be only present pre-ferred embodiments, therefore can not limit scope of the invention process according to this, the equivalence change namely done according to the scope of the claims of the present invention and description with modify, all should still belong in scope that the present invention contains.
