Description
Technical field
The utility model is related to a kind of stressed member of applied to high-speed railway touching net, more particularly to it is a kind of be used for contact line and
The anchoring wire clamp that carrier cable is connected with compensation device.
Background technology
Terminal anchoring clamp is stress part very crucial on contact net, in use with it by contact line and carrier cable with
Compensation device concatenation is integral, and the falling mound weight transfer of compensation device is made into contact line, carrier cable to contact line and carrier cable
The tension force for tense, stretching and obtain regulation, steadily takes stream and provides passage for electric locomotive or EMUs.High speed contact line level
Power is generally 25～30kN, and load rope tensility is 15～20kN, belongs to hightension supply line, and terminal anchoring clamp is because being serially connected in
In loop, also acted on by mentioned strain, this is the static(al) of terminal anchoring clamp.The contact net high vibration when locomotive passes through,
In addition nature is scraped the additional forces such as wind-induced swing and is acted also on terminal anchoring clamp, so terminal anchoring clamp is received for a long time
To the dynamic force that power is hightension.Part about more than 300 is planted on contact net, and crucial stress part has more than 40 to plant, and dead end anchor
Wire fixing clamp is the key in crucial stress part, is known as the king of part.Why thus, to be because that it is acted on particularly significant, it is
Guarantee traffic safety, it is high to the reliability requirement of terminal anchoring clamp on contact net.If there are quality problems, contact can be caused
Line or carrier cable come off, and contact net balance is destroyed, can cause contact net extensive damage, and this is the most serious in contact net
Accident, recovers general slow, easily causes big or great driving accident, normal railway transportation production and safety are constituted compared with
It is big to affect.
In external electrification developed country, the production technology of terminal anchoring clamp is：
A. Japan employs a pure copper tube for being about 300mm and a rod iron with monaural, then by means of mould liquid
Pressure equipment, when installing at the scene, first by rod iron insertion copper pipe one end, copper pipe other end insertion contact line or carrier cable, then will
Copper pipe continuously crimps into 5 sections with the rod iron and contact line or carrier cable of insertion, every section of pressure.Use rod iron one after having crimped again
The monaural at end is connected compositing terminal anchoring wire clamp with insulator.This terminal anchoring clamp complex structure, crimping is difficult to grasp.
B. the terminal anchoring clamp that moral, method, Spain, Italy produce is basically identical, and body is made up of two parts, upper half
Part is connection ears, and the latter half is the cylinder with endoporus, and two parts are using threaded connection.Body adopts casting.
Because casting technique is usually present casting flaw, such as pore, loose, slag inclusion, in order to avoid producing big casting flaw, especially
It is high to reliability requirement part as terminal anchoring clamp, it is high except requiring casting technique, reduce as far as possible
Outside casting flaw, finished product must adopt the piece inspection of nondestructive inspection, and such process yield is not high, can increase production
Cost, reduces production efficiency.Therefore, high to the reliability requirement optimal technique of terminal anchoring clamp is die forging.
Moral, method, west, the terminal anchoring clamp field installation process of Yi Deng states are：
A. contact wire's terminal anchor anchorage wire clamp：To load one in cylindrical hole in the cylinder body of the latter half of cable clamp structure
Individual small cylinder, is processed into taper hole in small cylinder, copper alloy chock is reinstalled in taper hole, and during installation, contact line is from body one
The entrance hole at end is entered, and through small cylinder, is then passed through chock endoporus, and locking device, wire clamp are constituted between chock and small cylinder
There is the gap of about 0.5mm between the endoporus and small cylinder of body one end.After stress, wire clip body is only subject to small cylinder downward
Pressure, built-in small cylinder is constantly shunk after contact line is penetrated by chock, and small cylinder is circumferentially gradually increased
Lateral pressure.Because of small cylinder wall thickness less, the reason for and because of gap, it is impossible to by pressure transmission to body wall.This knot
The contact wire's terminal anchor anchorage wire clamp tension force of structure can not be too big, and otherwise small cylinder can be cracked easily.
B. termination fitting for catenary：It is processed into without small cylinder, endoporus termination fitting for catenary the latter half
Cone.Carrier cable is copper-alloy stranded conductor, is typically formed by 19 strands of monofilament are stranded, and whole twisted wire is divided into three layers, and innermost layer is 1 list
Silk, the second layer is circular and surround by helix centered on internal layer by 7 monofilament, third layer (outermost layer) by 12 monofilament around
It is circular and circular by helix centered on the second layer.Chock is driven between the second layer and third layer during installation, and at this moment the 3rd
12 monofilament of layer require to break one by one it is straight, separate, be equidistantly uniformly distributed in the cylindrical outside of chock, i.e. chock and taper hole it
Between.This installation method is to destroy the outermost integrality of twisted wire first, because twisted wire transmission pulling force is stranded by 19 monofilament
And form a whole, between monofilament, mutually extrude because of close-packed arrays generate frictional force to balance external force between layers
's.But when monofilament separately after mutual extruding force disappear therewith, frictional force when only by compressing between monofilament and taper hole is putting down
Weighing apparatus external force.The ability of so carrier cable opposing external force can decline.In addition, monofilament is that copper alloy wire is very hard, preformed rear generation plasticity
Deformation is difficult to be broken directly with hand, therefore is difficult uniformly to be equally spaced.It is slightly improper, or monofilament can occur unavoidably in drawing process
Micro- slip, it is possible in being embedded into the shrinkage joint of chock, causes chock to shrink, and then can not set up twisted pair wire gradually to increase
Big pressure, such twisted wire is easy to extract out, comes off because of outer tension force, causes accident.
Terminal anchoring clamp is arranged on a thousand li railway line on the contact net of Ullage ground about 6m, and field ring is born for a long time
Border, such as wind, frost, rain, snow, high temperature, severe cold, environmental corrosion effect, mechanical oscillation, wind swing also from locomotive etc.,
Condition of work is very harsh, and to guarantee traffic safety, terminal anchoring clamp must reliably hold line, rope and not release,
Here chock effect is very crucial.High ferro carrier cable tensile strength in more than 480MPa, high ferro contact line 510MPa with
On, the high magnesium carrier cable pull-off forces of CTMH150 are in 82.8kN.Above-mentioned line, rope case hardness are generally individually in Bu Shi 160 or so, chock
Bite line, rope that will be reliably and with long-term not be released, and only its intensity and case hardness should be higher than that line, rope, just can make tooth be embedded into line,
Rope surface, otherwise, chock tooth can deform, rust and sting incessantly line, rope.
It is inadequate, also formal parameter only to meet mechanical property, such as chock length, taper, diameter of bore and tolerance,
Endoporus profile of tooth, the number of teeth, surface roughness, shrinkage joint shape etc. are also all very crucial.Friction between chock endoporus and line, rope surface
The matching relationship between coefficient of friction between coefficient and tapered sleeve and chock outer surface also all affects reliability.Come in terms of material
Say, the cleat material of the terminal anchoring clamp such as moral, method is CuNi2Si, and intensity, hardness and contact line are basically identical, intensity
480MPa, hardness is HB160 or so.Domestic high ferro is 170 or so with high magnesium contact line case hardness, and with CuNi2Si chock is made
Occlusion is unreliable, because under extruding force effect, the easy rust of chock tooth, or even bending, it is susceptible to slip.Therefore, Europe
The used chock in continent is used only once.For in terms of the appearance and size, European chock taper is big, is 1:8, because axial dimension becomes
X, the resistance that moves ahead is big；Length is short, is 47mm, and the number of teeth is few, and each crown upper stress is big, and profile of tooth is easily damaged, and is isosceles triangle
Helical tooth, stress is unreasonable.Because Europe is without high intensity, hightension 150mm2Contact line and carrier cable, contact net tension force is less,
Therefore the tension force of terminal anchoring clamp can meet the use of European contact net.And use the exclusive hightension contact net of China with
And cross-sectional area is 150mm2Contact line or carrier cable on, reliability is poor.
