Description

66KV inner wedge type strain fast wire clamp fixture
Technical Field
The utility model belongs to electric power transmission line live working field, the quick fastener fixture of wedge type strain insulator in 66 kilovolts promptly.
Background
In prior art, quick fastener is the novel line gold utensil that newly drops into use in recent years, adopt this equipment line strain clamp drainage wedge fastening mode to connect, do not have special fixture when needing to change 66kV strain insulator's live working with electricity, adopt the wire clamping unit pulley group emergency line to get into electric field wire clamping unit through the jib flat ladder by allelism and change the insulator, the drainage swing is big when having the emergency line, control difficulties, safe distance is little, the work load of equipotential operation personnel is big, the auxiliary staff is many, unfavorable factors such as operating time length.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: the provided 66KV inner wedge type strain insulator quick clamp can be used for replacing a strain insulator string in a live-wire mode on strain insulator single-connection connecting equipment using a quick clamp by adopting a conventional live-wire operation method.
The technical solution of the utility model is that: a66 KV inner wedge type strain fast wire clamp fixture is characterized by comprising a wire clamp conical barrel, wherein a wire can pass through the middle of the wire clamp conical barrel, the rear portion of the wire clamp conical barrel is fixedly sleeved with a ring sleeve, the rear end faces of two ends of the ring sleeve are connected with U-shaped bolts in an inserting and screwing mode, the rear end of each U-shaped bolt is connected with a wire clamp connected with an insulator string, two end heads of each wire clamp are provided with connecting ring holes, and a connecting pin shaft is inserted in each ring. This instrument is connected through insulating arm-tie with original 66kV strain insulator wing section fixture (cross arm end), will hold in the palm the bottle frame again and install on both sides wing section fixture, and original 66kV strain insulator wing section fixture (cross arm end) is installed on cross arm side U-shaped link, and 66kV strain insulator quick clamp fixture is fixed on quick fastener, shifts insulator tension through adjusting the lead screw to the work of changing the insulator with electricity carries out.
The utility model has the advantages that: the insulator string of the 66kV single-connection strain rapid wire clamp can be replaced in an electrified manner; the structure is simple and reasonable, and the use is safe and reliable; the problem that a 66KV strain fast wire clamp does not have a special clamp is solved.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Detailed Description
Referring to fig. 1, the part names are as follows: the cable clamp comprises a cable clamp conical barrel 1, a ring sleeve 2, a U-shaped bolt 3, a cable clamp 4, a ring hole 5, a pin shaft 6 and a lead 7.
Referring to fig. 1, a 66kv internal wedge type strain fast wire clamp fixture is characterized by comprising a wire clamp conical barrel 1, wherein a lead 7 can pass through the middle of the wire clamp conical barrel 1, a ring sleeve 2 is fixedly sleeved on the rear part of the wire clamp conical barrel 1, U-shaped bolts 3 are inserted and screwed on the rear end surfaces of two ends of the ring sleeve 2, the rear ends of the U-shaped bolts 3 are connected with wire clamps 4 connected with an insulator string, two end heads of each wire clamp 4 are provided with connecting ring holes 5, and connecting pin shafts 6 are inserted and connected in the ring holes 5.
Referring to fig. 2-4, the part names are as follows: the lock comprises an arch-shaped groove 8, an oval shallow groove 9, an oval shallow groove 10, a first pin lock 11, a second pin lock 12 and a third pin lock 13.
Referring to fig. 2-4, referring to fig. 2, the fixture is provided with an arch groove 8 in the middle according to the outer diameter of the wire clamp taper barrel 1, so that the fixture can straddle the wire clamp taper barrel 1.
The two sides of the structure of the arched groove 8 are processed with elliptical shallow grooves 9, the size of the elliptical shallow grooves 9 is slightly larger than the diameter of the U-shaped screw of the wire clamp shown in figure 1, the installation and the positioning are convenient, the displacement of the clamp after being stressed in the use process is also prevented, and the two points are also used as stress points of the clamp. The tension transfer device has the advantage that the tension borne by the insulator string can be transferred under the condition that the original stress mode of the quick wire clamp is not changed.
The using method comprises the following steps: referring to fig. 2-4, the device is connected with an original 66kV strain wing-shaped clamp and a screw rod by an insulating pull plate and is fixed by a second pin lock 12 and a third pin lock 13. The clamp is spanned on a wire clamp conical barrel 1 of a quick wire clamp and is fixed through a first pin lock 11, so that the clamp is prevented from falling off after being stressed; the bolts at the two sides of the quick wire clamp are clamped in the oval shallow grooves 10 at the two sides of the arch structure, so that the clamping apparatus is prevented from being displaced after being stressed in the use process. The method comprises the steps of reliably installing an original 66kV strain wing-shaped fixture on the cross arm side of an insulator string according to a conventional method, tightening the distance between the fixture and the original 66kV strain wing-shaped fixture by screwing a lead screw, and transferring the tension of the insulator string to fixtures at two ends, the lead screw and an insulating pull plate, so that the purpose of replacing the insulator string is achieved.
The above description is only exemplary of the present invention, and the various illustrations do not limit the essence of the present invention.
