Abstract
There is the rub strain clamp of the equal pressure pad of cream of increasing to disclose a kind of filling of twisted wire stock gap and increase the strain clamp that rub cream, one group of U bolt share equal pressure pad.By wire clamp 1, U bolt 2, increases rub cream 3, equal pressure pad 4 and form.Filling increases the cream 3 that rubs in stock gap in the twisted wire section that wire clamp 1 clamps.There is shared equal pressure pad 4 to contact under the clamp of one group of U bolt 2 for being fixedly mounted with twisted wire with twisted wire.When stringing, the cream 3 that rubs will be increased and be coated in the twisted wire section outer surface contacted with wire clamp 1, then normotopia is put in wire clamp 1.One group of U bolt 2 mounts a beginning from wire clamp 1, is successively mounted in the fixed bit of wire clamp 1, and equal pressure pad 4 is made to install U bolt 2 against twisted wire, finally uniformly tightens the nut of one group of U bolt 2.Increase the compression filling twisted wire stock gap of cream 3 of rubbing, the reality for increasing wire clamp 1 and twisted wire has contact surface, and frictional resistance increases；Equal pressure pad 4 extends the sphere of action of U bolt 2；Enhance the chucking power of 1 twisted pair wire of wire clamp.For high voltage power transmission.
Description
Technical field
There is the rub strain clamp of the equal pressure pad of cream of increasing to be related to power transmission and distribution project technology, and in particular to a kind of twisted wire stock gap filling increases
Rub cream, one group of U bolt shares the strain clamp of equal pressure pad.
Background technique
For steel-cored aluminium strand to be fixed on strain insulator, the strain clamp on corner pole insulator chain, there are two types of: one is
Screw bolt-type；One is crimp types.The advantages of bolt-type strain clamp is easy for installation, as long as being not necessarily to crimping apparatus one spanner,
It is widely applied；The disadvantage is that wire clamp clamping face cannot be bonded closely with twisted wire outer surface because twisted wire surface is there are stock gap；Add
One of group U bolt clamp it is respectively independent, the chucking power of twisted pair wire is formed under bolt and is sent by tight, bolt, fails balanced pressure.
" cannot be bonded closely ", " failing balanced pressure " influence the chucking power of wire clamp.In addition, the presence of stock gap, it can be because of the wind of twisted wire
Pendulum causes hard defects to wear, is extended from wire clamp mouth into wire clamp, slides and hides some dangers in wire clamp for twisted wire, practical just to have strand
Line slides in wire clamp, causes the accident of wire jumper touching cross-arm ground connection.
Summary of the invention
The rub strain clamp technical problems to be solved of the equal pressure pad of cream of increasing are: eliminating the stock in wire clamp and twisted wire contact-segment
Gap, the reality for increasing wire clamp and twisted wire has contact surface, to enhance the chucking power of wire clamp.
The technical solution adopted is that: the filling of twisted wire stock gap increases the cream that rubs, and one group of U bolt, which adds, shares equal pressure pad.
There is increasing to rub the strain clamp (attached drawing) of the equal pressure pad of cream, by wire clamp 1, U bolt 2, increases rub cream 3, equal pressure pad 4 and form.
Filling increases the cream 3 that rubs in stock gap in the twisted wire section that wire clamp 1 clamps.Have under the clamp of one group of U bolt 2 for being fixedly mounted with twisted wire shared equal
Pressure pad 4 is contacted with twisted wire.
When stringing, the cream 3 that rubs will be increased and be coated in the twisted wire section outer surface contacted with wire clamp 1, then normotopia is put in wire clamp 1.
One group of U bolt 2 mounts a beginning from wire clamp 1, is successively mounted in the fixed bit of wire clamp 1, and equal pressure pad 4 is made to install U against twisted wire
Shape bolt 2 finally uniformly tightens the nut of one group of U bolt 2.
The rub beneficial effect of strain clamp of the equal pressure pad of cream of increasing is: the increasing filling that is pressurized of cream 3 that rubs for being applied to twisted wire surface twists
In the stock gap of line, the reality for increasing wire clamp 1 and twisted wire has contact surface, and frictional resistance increases；Equal pressure pad 4 makes every U bolt 2 just
Pressure influence range extends between two U bolts 2；It works along both lines, enhances the chucking power of 1 twisted pair wire of wire clamp.
Detailed description of the invention
Attached drawing is that have increasing to rub the strain clamp structural schematic diagram of the equal pressure pad of cream.
In figure: 1-one wire clamp；2 --- U bolt；3 --- increase the cream that rubs；4 --- equal pressure pad.
Specific embodiment
Increase rub cream 3 be normal temperature cure waterproof glue and aluminium powder and at without self drainage filling paste.
Equal pressure pad 4 is hot galvanizing quadrangular A3 steelwork.The cancave cambered surface diameter contacted with twisted wire is the same as twisted wire diameter；Its excess-three
Face is plane, and wherein there is the arc-shaped shallow slot coincideing with U bolt bottom in top surface；Two sides interplanar distance is slightly less than twisted wire diameter.Equal pressure pad 4
Length is the same as 1 solidus segment length of wire clamp.Cross section concave arc midpoint thickness 10mm.
