Abstract

The utility model relates to an auxiliary tool for crimping a lead wire, in particular to anti-looseness clamp for crimping a lead wire of a power transmission line. The anti-looseness clamp comprises a semicircular left clamping shell and a semicircular right clamping shell, wherein one side of the left clamping shell is movably connected with one side of the right clamping shell through a shaft pin; the edge of the other side of the left clamping shell is provided with a plurality of fastening bolts with fastening nuts through a shaft pin; the edge of the other side of the right clamping shell is provided with a plurality of clamping slots which correspond to the plurality of fastening bolts on the left clamping shell and are matched with the fastening bolts; and an inner clamping tube is fixedly connected to the inner side of each of the left clamping shell and the right clamping shell. The anti-looseness clamp has a simple structure, is convenient to carry and use, and has the advantages of saving time and labor, solving the quality problem of looseness or digging of the lead wire, increasing the success rate of lead wire connection, avoiding repeated reworking and improving the work efficiency of crimping the lead wire.

Description

A kind of power transmission sequence crimping lead is prevented release clamp
Technical field:
The utility model relates to a kind of conductor compression jointing and uses aid, and especially a kind of power transmission sequence crimping lead is prevented release clamp.
Background technology:
Lead hydraulic pressure continues and constructs is an important hidden operation in the construction of transmission line stringing.It is the important assurance of transmission line safe operation that the holding of splicing sleeve and strain clamp and lead puted forth effort.Along with improving constantly with transmission line capability of transmission line electric pressure in recent years is increasing, conductor cross-section also strengthens thereupon, and is also higher to the compression joint technique quality requirement.Under the traditional work pattern, the construction that continues of spreading conducting wire is carried out at tension field usually, and mostly construction environment is finite regions such as mountain area, mire, the woods; Operating personnel adopt press-connection machine that splicing sleeve and lead are carried out crimping, the phenomenon of lead pine thigh or plane thigh usually can occur, can only lead be cut-off at present for this phenomenon and carry out the crimping construction again; Both wasted time and energy like this; Increased material consumption again, the lead jointing-success-rate is low, inefficiency.
The utility model content:
The utility model provides a kind of power transmission sequence crimping lead to prevent release clamp, and it is simple in structure, portably uses conveniently; Time saving and energy saving; The quality problems that solved lead pine thigh or dug thigh have improved the success rate that lead continues, and have avoided repeating to do over again; Improve the operating efficiency of conductor compression jointing, solved the problem that exists in the prior art.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises semicircular left side folder shell and right folder shell; One side of left side folder shell and right folder shell flexibly connects through a pivot pin; The opposite side edge of folder shell evenly is provided with the fastening bolt that several are with clamp nuts through a pivot pin on a left side, and several fastening bolts on the folder shell of the corresponding left side, opposite side edge of right side folder shell are provided with the draw-in groove that several cooperate with fastening bolt; The folder shell is fixed with clamp in respectively with the inboard of right folder shell on a left side.
The utility model is simple in structure, portably uses conveniently, and is time saving and energy saving, and the quality problems that solved lead pine thigh or dug thigh have improved the success rate that lead continues, and have avoided repeating to do over again, and have improved the operating efficiency of conductor compression jointing.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left view of Fig. 1.
Among the figure, 1, left side folder shell; 2, right folder shell; 3, clamp nut; 4, fastening bolt; 5, draw-in groove; 6, interior clamp.
Embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, the utility model is discussed in more detail in conjunction with its accompanying drawing below by the specific embodiment.
Shown in Fig. 1~2; The utility model comprises semicircular left side folder shell 1 and right folder shell 2; One side of left side folder shell 1 and right folder shell 2 flexibly connects through a pivot pin; The opposite side edge of folder shell 1 evenly is provided with the fastening bolt 4 that several are with clamp nuts 3 through a pivot pin on a left side, and several fastening bolts 4 on the folder shell 1 of the corresponding left side, opposite side edge of right side folder shell 2 are provided with the draw-in groove 5 that several cooperate with fastening bolt 4; Folder shell 1 is fixed with clamp 6 in respectively with the inboard of right folder shell 2 on a left side.The thickness of interior clamp 6 is according to treating that the diameter variation of crimping lead changes.Said left side folder shell 1, right folder shell 2 and interior clamp 6 are aluminum.
During use, unscrew clamp nut 3, fastening bolt 4 is deviate from from draw-in groove 5; Open left side folder shell 1 and right folder shell 2; A left side is pressed from both sides shell 1 be installed in apart from splicing sleeve one end 10cm place, support with the extension that prevents aluminum pipe in the crimping process and bump anti-release clamp, and then fastening bolt 4 is snapped in the draw-in groove 5 with right folder shell 2; The clamp nut 3 of screwing presss from both sides shell 1 with a left side and fixes with right folder shell 2.When carrying out 300~720mm 2When lead adopts positive platen press crimping, the anti-release clamp of a utility model is installed respectively in the both sides of splicing sleeve; When carrying out 800~1000mm 2When lead adopts along the platen press crimping,, only the anti-release clamp of a utility model is installed and is got final product at the distolateral tail end 10cm place of end at the initial distolateral anti-release clamp of the utility model of need not installing of crimping.
The anti-release clamp of employing the utility model, simple to operation, time saving and energy saving, the quality problems that solved lead pine thigh or dug thigh have improved the success rate that lead continues, and have avoided repeating to do over again, and have improved the operating efficiency of conductor compression jointing.
The utility model does not detail part, is those skilled in the art of the present technique's known technology.
