Abstract
The invention relates to the tool field, particularly a pliers-type hot-line work chucking appliance for replacement of a composite insulator in a transmission line, and a use method thereof. The chucking appliance is composed of a chucking appliance body installed with a U-shaped groove and a screw rod hole, a screw rod with a locating block and a screw rod spanner, and characterized in that a fastening groove is formed on the chucking appliance, a fastening bolt is arranged inside the fastening groove and a fastening hook is arranged on the fastening bolt. The chucking appliance solves the problem that the prior straight-line chucking appliance has single function, thereby suiting all types of tangent towers. Fastening elements prevent the chucking appliance from loosening and inclining and prevent the two sides of a cross arm angle iron from deforming, and the chucking appliance has the advantages of flexible operation, good practicability, high work efficiency, and high safety.
Description
Technical field:
The present invention relates to field of tool, specifically a kind of clamp type hot-line work fastener and using method of changing synthetic insulator in the transmission line.
Background technology:
As everyone knows, insulator is the consumable accessory in the transmission line, the general suspension string holder that uses when changing insulator, suspension string holder is by the fixture body that is provided with U type groove and lead screw hole, the leading screw and the leading screw spanner of band locating piece are formed, draw-in groove one side is provided with the holding screw handle on the fixture body, lead screw hole can be provided with the screw thread that is meshed with leading screw, be meshed with leading screw draw-in groove and guide pillar also can be set on fixture body, this jig can only be applicable to straight line cement pole and single time tangent tower, jig is installed on the angle bar of insulator hanging point top when being applied to cement pole, because the length of the cross arm insulator hanging point place angle bar of iron tower is than the weak point about 1/3 of cement pole, so the suspension string holder that uses on the iron tower can only be installed on the angle bar on cross-arm both sides and use, because angle bar length and specification there are differences, the load coefficient of cross-arm both sides angle bar obviously reduces, so, jig can not be at double, press down than special tangent towers such as Da Ta and big crossing span towers and use, in addition, this jig is stuck in that use can make the vertical direction of jig and lead have certain included angle on the angle bar on cross-arm both sides, the opening direction of jig U type groove is identical with lead just, make the leading screw of jig not swing along the lead vertical direction, limited the operability of leading screw and jig, owing to only have the 1-2mm gap between U type groove and leading screw, according to present all types tangent suspension tower cross-arm structure situation, when jig leading screw inclination angle during greater than 5 °, leading screw and jig can exist the dead angle stuck phenomenon to occur, leading screw is monolateral stressed excessive, operate very difficultly, and have very unsafe factor.
Summary of the invention:
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of flexible operation, practical, clamp type hot-line work fastener and using method that fail safe is good are provided.
The present invention can reach by following measure:
A kind of clamp type hot-line work fastener is made up of the leading screw and the leading screw spanner of the fixture body that is provided with U type groove and lead screw hole, band locating piece, it is characterized in that fixture body is provided with binding groove, is provided with fastening bolt in the binding groove, and fastening bolt is provided with fastening hook.
The present invention can be provided with T type pad in binding groove, fastening bolt is connected with binding groove through T type pad, to increase handling and useful life of the present invention.
Can be provided with the nut of screw thread and band swing handle among the present invention on the fastening hook, fastening hook is connected with fastening bolt through the through hole that fastening bolt is provided with, to enlarge range of application of the present invention.
Using method of the present invention is:
1, the U type groove with clamp type hot-line work fastener connects on the angle bar that is stuck in the insulator top,
2, adjust the relative position of fastening hook and fastening bolt, with the angle bar chucking,
3, with the leading screw of leading screw spanner accommodation zone locating piece, open and hang cable.
The present invention has changed the function singleness of former suspension string holder, can be applicable to present all types tangent tower, reason owing to securing member, there is not the phenomenon of loosening inclination in jig, and phenomenons such as all stressed difficult generation distortion in cross-arm angle bar two sides have advantages such as flexible operation, practical, high efficiency, fail safe height.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment:
Below in conjunction with accompanying drawing the present invention is further described:
As shown in drawings, a kind of clamp type hot-line work fastener, by the fixture body 1 that is provided with U type groove and lead screw hole, the leading screw 2 of band locating piece and leading screw spanner 3 are formed, above-mentioned same as the prior art, this does not give unnecessary details, feature of the present invention is that fixture body 1 is provided with binding groove, be provided with fastening bolt 4 in the binding groove, fastening bolt 4 is provided with fastening hook 5, the present invention can be provided with T type pad 6 in binding groove, fastening bolt 4 is connected with binding groove through T type pad 6, to increase handling and useful life of the present invention, can be provided with the nut 7 of screw thread and band swing handle among the present invention on the fastening hook 5, fastening hook 5 is connected with fastening bolt 4 through the through hole that fastening bolt 4 is provided with, to enlarge range of application of the present invention, using method of the present invention is: the U type groove with clamp type hot-line work fastener connects on the angle bar that is stuck in the insulator top earlier; Adjust the relative position of fastening hook and fastening bolt again, tighten with angle bar; Use the leading screw of leading screw spanner accommodation zone locating piece at last, open and hang cable.
