Description
Technical field
The present invention relates to the technical fields of strain clamp, more particularly to a kind of strain clamp structure of power engineering.
Background technique
Strain clamp to bear wire tension, and conducting wire is hung to the gold in strain insulator-string group or shaft tower for fixing conducting wire
Tool, strain clamp are used to for conducting wire or lightning conducter being fixed on non-rectilinear shaft tower strain insulator string, and anchor effect is also used to fix
The bracing wire of bracing wire shaft tower, for corner, connecting and the connection of terminal.Spiral aluminum-clad steel wire has extremely strong strain insulator intensity, no collection
Middle stress plays the role of protection and auxiliary vibration damping to optical cable.
Existing strain clamp skids in wire clamp in use, being not connected firmly and being easy to produce power transmission line, compares different rulers
The position and dynamics difference that very little power transmission line clamps, the position that holds out against for being easy to appear disengaging bolt under external force cause to beat
It is sliding, cause power transmission system to break down.
Summary of the invention
The present invention is provided to the strain clamp structures of power engineering line, and being connected firmly will not make power transmission line in wire clamp
Interior skidding is not in the different situation of clamping force due to size difference in the various sizes of power transmission line of fixation, reduces and beat
Sliding probability works more stable.
The technical solution of the present invention is as follows:
A kind of strain clamp structure of power engineering, including left clamp and right clamping plate, the medial surface of the left clamp are opened
Equipped with wire casing, the two sides of the wire casing are equipped with raised line, and the medial surface of the right clamping plate, which is equipped with, cooperates the wire casing to carry out cable
The clamp block of clamping, the two sides of the clamp block are equipped with the groove being adapted to the raised line, the left clamp and the right clamping plate
It offers several connecting holes, the left clamp and the right clamping plate and is attached using bolt across the connecting hole, institute
It states left clamp and the right clamping plate is equipped with extension board, being run through on the extension board by the connecting hole has fixing bolt, should
Strain clamp structure is fixed on the fixed frame of electric pole by the fixing bolt.
Among two raised lines that power transmission line is placed on the inside of left clamp, power transmission line is then filled in wire casing, then by left clamp
It is fastened with right clamping plate, holds out against clamp block cooperation wire casing to power transmission line, raised line is fitted into groove, then bolt is mounted on two
It the connection hole of clamping plate and tightens, is mounted on the fixed frame of electric pole finally by the fixing bolt on extension board
Complete installation.
Further, the wire casing is V-shaped groove, and the wire casing is consistent with the bending direction of the left clamp.The wire casing of V-arrangement
It is adapted to the installation of various sizes of power transmission line, is clamped power transmission line with clamp block after installation, makes to clamp stronger, is reduced not
With size power transmission line it is fixed after directly it clamped with bolt cause cylindrical power transmission line to be detached from bolt and hold out against to cause to transmit electricity
The probability of the system failure.
Further, the raised line is protruded from by one-pass molding on the medial surface of the left clamp, and the raised line and institute
The bending direction for stating left clamp is consistent.Due to pullling when power transmission line installation, power is excessive to be not easy to that power transmission line is directly mounted on wire casing
It is interior, first power transmission line can be placed among the raised line of two sides, power transmission line is filled in into wire casing again, raised line also plays when in use
The function of the relative position of fixed two panels clamping plate.
Further, the clamp block protrudes from the medial surface of the right clamping plate by one-pass molding, and the clamp block with
The bending direction of the right clamping plate is consistent.
Further, the cross section of the clamp block is square boss, and the position of the position of the clamp block and the wire casing
Set correspondence.Left clamp and right clamping plate close to when, the clamp block of convex holds out against the power transmission line in wire casing, makes power transmission line by three
The clamping force in direction, it is not easy to occur being detached from the case where clamping.
Further, the groove is depressed in the medial surface of the right clamping plate, and the position of the groove by one-pass molding
It is corresponding with the position of the raised line.The effect of groove is cooperation raised line work, avoids the opposite position of the two sides raised line in left clamp
Change is set, the case where power transmission line directly drops in the case where bolt failure is also prevented.
Further, the extension board of the left clamp and the extension board of the right clamping plate are correspondingly arranged, and two extensions
There are cracks between plate.During installation convenient for the strain clamp structure, the fixed frame of electric pole is made to be clipped in the extension board of left clamp
In crack between the extension board of right clamping plate, connecting hole, the electric pole of an extension board are then sequentially passed through with fixing bolt
The installation screw of fixed frame and the connecting hole of another extension board complete installation.
The invention has the benefit that
The present invention has carried out the addition in function on the basis of the existing cable clamp structure for power engineering line, main
It is embodied in: increasing the structure of V-shaped line slot in the left clamp of this structure, conveniently adapt to various sizes of power transmission line, work
When power transmission line held out against in V-shaped line slot by clamp block, keep the fixation of power transmission line more reliable, be less prone to skidding；In this structure
The structure of raised line is increased in left clamp, first during installation, power transmission line is too tight, pulls the excessive inconvenience of power directly by power transmission line
It is mounted in wire casing, power transmission line is positioned in wire casing step by step using raised line, when in use the groove pair of raised line and right clamping plate
Button plays the case where preventing left clamp and right clamping plate from misplacing, also prevents power transmission line in the case where bolt failure direct
The case where tenesmus；In view of the foregoing it is apparent that facilitate installation than existing strain clamp, the cooperation of raised line and groove when use
The relative position that can play the role of further fixing two panels clamping plate also prevents power transmission line in the case where bolt failure direct
The case where tenesmus, while passing through the cooperation of wire casing and clamp block, it is not in because of size in the various sizes of power transmission line of fixation
Different and situation that clamping force is different, reduces the probability of skidding, works more stable.
