Description
Technical field
The invention belongs to power network line power tool technical field, and in particular to a kind of backman for transmission line of electricity stringing
Tool.
Background technology
At present, in electric transmission line erection construction, particularly transmission line high-altitude wire stringing operation often will be sliding using iron wire or steel wire
Wheel is fixed on shaft tower and drawn, and to carry out stringing and hanging wire to circuit, but this operating type has many drawbacks：It is first
First, because iron wire is easily deformed in stress and makes lack of standardization, needing to be closely wound in fastening prevents from loosening, during dismounting
It is inconvenient, governs operating efficiency；Secondly, iron wire stress tenesmus, causes hanging wire point substantially to make difficulty of construction high compared with low head,
The degree of accuracy is hammered into shape after reducing, it is necessary to which forward lean test is lifted into operation, and security is poor；3rd, iron wire or fixation with steel wire traction
The mode of wheel, height fall large traction is big in distraction procedure, easily causes the phenomenon that iron wire or steel wire disconnect, easily breaks absolutely
Edge；4th, the mode insulator easy to wear that iron wire is fastened.
Accordingly, it would be desirable to which a kind of new tool changes the deficiency of current technology.
The content of the invention
Present invention aim to address prior art exist inefficiency, error are big and security is low technical problem there is provided
A kind of transmission line of electricity stringing aid, to overcome the deficiencies in the prior art.
A kind of transmission line of electricity stringing aid of the present invention, it includes c-type deck；The openend difference of the c-type deck
Provided with mutual corresponding silk hole, and silk is mutually fastened by screw mandrel between silk hole connect；Side at the top of the c-type deck is provided with branch
Pushing out ring；The support ring is provided with the support shaft for mutually rotating and being connected with it, and support shaft is mutually limited by nut I with support ring
Position clamping.
In order to improve support strength and be easy to grasp, the c-type deck is provided with reinforcement.
The present invention another inventive point be：
In view of c-type deck is main member, the clamping that directly can be fitted with the component of steel tower will not be rotated；Insulator relatively sinks, and
And height is high, it is necessary to the weight born is larger, this requires the tensile strength and bending strength of c-type deck all than larger, and
Possesses preferable frictional force；Based on above-mentioned technical problem,
Present invention also offers a kind of c-type deck, it is prepared by the raw material of following parts by weight：Cobalt 5.1%, chromium 3.2%, copper
2.9%, nickel 1.7%, vanadium 0.5%, graphite 0.1%, cerium 0.01%, samarium 0.01%, remaining is iron.
The preparation method of above-mentioned c-type deck comprises the following steps：
Each raw material is weighed according to parts by weight, iron is divided into two equal portions first, first toward the iron of input half quality in ball mill, then
Cobalt, chromium, copper, nickel, vanadium, graphite, cerium and samarium are put into successively, are well mixed, the mass ratio 3 of ball material:1, abrasive media is ethanol,
The ratio of ethanol and compound is lL：1Kg, Ball-milling Time is 10h, then adds the iron of second half quality, continues ball milling 10h,
Obtained powder passes through spray-drying process, and compressing, is put into 8MPa low-pressure sintering furnace in 1400 DEG C of insulations
30min, then 5-10 DEG C/min speed are cooled to 400 DEG C, under nitrogen protection, sensing heating 20 seconds, then control blank
Temperature, which is moved under conditions of 700 DEG C -750 DEG C, quickly to be forged in finish forge mould, is stripped and produces.
The beneficial effect that the present invention is obtained mainly includes but is not limited to the following aspects：
1st, hammer the degree of accuracy after improving into shape, shaft tower pulley can be improved to mounting point parallel position, it is to avoid personnel are by viewing angle
It is in larger distance causing with actual hanging wire range deviation with drop, improve hammer observation accuracy after wire.
2nd, operational security is improved, the overall structure of triangle ensures to be brought into close contact admittedly with the angle iron component on shaft tower
Fixed, the mechanical strength of pulling force and tension force has all reached the job requirements of shaft tower stringing hanging wire, it is ensured that the security of operation.
3rd, effectively prevented traction, snatch block and shaft tower hanging point parallel position can be lifted, and insulator is hung with shaft tower
It is sufficiently close between point, mounting operation is can easily achieve in shorter adjustable range, is drawn without crossing.
4th, simple to operate, durability is strong, and front hanging method can be used to carry out wire stringing operation, the distance between hanging point is shortened,
One people can complete stringing hanging wire operation on shaft tower, and without operation of leaning forward of stretching forward, the iron wire of insulator is wrapped up without dismounting,
Outlet operation is less used, operating efficiency is improved, the construction operation time is reduced.
5th, the present invention uses high temperature sintering, then fast cooling, then is incubated, so that more cobalts of solid solution in Binder Phase,
Chromium, copper and nickel, improve dislocation energy, add the hardness, intensity and frictional force of material；The present invention is by adding trace rare-earth member
Element so that the uniformity in length and breadth of interiors of products institutional framework, alloy powder is uniformly dispersed, and improves decay resistance and wear-resisting
Property；The present invention selects various metals and nonmetallic raw material, reasonable mixture ratio, mechanical performance in every respect by multiple orthogonal test
Show preferable performance, it is adaptable to make the metalwork of high request；Preparation technology simple possible of the present invention, can be extensive
Industrialized production, possesses preferable market application foreground.
