Description
Technical field
A kind of Maintenance of Electric Transmission Line technical field of tools of the present invention, and in particular to great tonnage hydraulic cord holder.
Background technology
China electrical distribution is uneven, it is necessary to long distance powedr transmission, in order to reduce loss and improve power transmission efficiency, more and more
Using extra-high voltage and super UHV transmission, correspondingly the diameter of power transmission line and ground wire is also increasing, its weight is also very big, in band
During monolithic insulator in charged renewal edge substring, in order to ensure live line work safe distance, it is necessary to by power transmission line lifted one end away from
From, it is laborious time-consuming due to unsuitable hoisting tool, it is necessary to which maintenance personal pulls or jacks, and there are security risk.
Therefore during single insulator string in six strain insulator edge substring of charged for replacement, hydraulic wire grip as tightening, replace
Composite insulator use.In extra-high voltage alternating current-direct current transmission line of electricity, the division layout division arrangement of generally use six of conducting wire, with
Conventional supertension line is compared, and conducting wire vertical load is significantly increased.At present, UHVDC Transmission Lines power tool and utensil be very
It is few.Because the pulling force that extra high voltage direct current transmission line tangent tower insulator chain is born is far longer than supertension line, choosing
Select intensity height, light weight, safe and reliable Work tool material and be to ensure that scene can be with the key of practical operation.But mesh
Before, cord holder is made of Steel material, and in order to meet intensity requirement, most heavier mass, worker bears very in working at height
Greatly, the efficiency that risk factor and influence when adding construction are constructed.
The utility model of Publication No. 203553743U discloses a kind of great tonnage hydraulic cord holder, it contains hydraulic pump
Body and operation handle, are provided with hydraulic oil and piston rod in the pump housing, the outer end of the pump housing and piston rod sets one respectively
A connector, a U-type groove is set on the connector, the U-type groove is provided with bolt.Pulling force biography is provided with the connector
Sensor, the pulling force sensor are connected by controller with alarm.The nominal operating duty of the piston rod is 150kN, work
It is 600mm to make adjustments stroke.For the hydraulic wire grip in order to meet the requirement of live load, weight is larger, when replacing insulator
The muscle power of worker wastes very serious.
The content of the invention
In view of this, the present invention provides a kind of great tonnage hydraulic cord holder, is made, had of titanium alloy that specially developing
The characteristics of intensity is high, light weight, can be adapted for replacing insulator in extra-high voltage alternating current-direct current transmission line of electricity, and cause hydraulic line tightening
For device compared with traditional cord holder, weight reduces nearly half, significantly reduces the burden of staff when replacing insulator, adds
The fast efficiency of work.
In order to solve the above technical problems, the present invention provides a kind of great tonnage hydraulic cord holder, the pump of the hydraulic wire grip
Body and piston rod use titanium alloy product, the titanium alloy by weight percentage by：Fe：2~4%, Sn：1.6~2.4%, Mo：

Compare, difference is little, but the density ratio steelwork of titanium alloy is much lower, therefore hydraulic wire grip made of titanium alloy is reaching
During identical tensile strength, its own weight smaller, easy to carry, operation, for the burden smaller of staff.
And titanium alloy corrosion resistance is fine, and oxidation resistance is strong, and preserve for a long time to get rusty when not in use,
And service life more more convenient than traditional hydraulic wire grip is longer in storage, a little very more.
The titanium alloy of the present invention is even more for its Functional Design for realizing of needs, to reach lighter weight and higher
Tensile strength.Er is rare earth element, when rare earth element is added in titanium alloy, between rare earth element is captured in titanium alloy substrate
Gap oxygen element, improves the toughness of alloy.In addition rare earth element can form second-phase dispersion particle, can crystal grain thinning, increase position
Dislocation density, is conducive to improve the tensile strength and creep resistance of alloy.The zirconium and molybdenum of addition, can dramatically increase tensile strength,
A small amount of titanium and zr element dissolve in Mo substrate, increase structural stability, recrystallization temperature are improved, by the displaced type in Mo substrate
Element (titanium, zirconium) reacts to each other with interstitial element (carbon), and to form disperse caused by the precipitation of spherical composite carbide particle strong
Change, improve the elevated temperature strength and creep-resistant property of molybdenum.
The great tonnage hydraulic cord holder of the present invention is made of titanium alloy that specially developing, high, light weight with intensity
Feature, can be adapted for replacing insulator in extra-high voltage alternating current-direct current transmission line of electricity, and cause hydraulic wire grip and traditional stringing
Device is compared, and weight reduces nearly half, significantly reduces the burden of staff when replacing insulator, accelerates the effect of work
Rate.
