Technical field
The present invention relates in electric railway contact net technology, the contact line of more particularly to overhead type contact net is downward
The e measurement technology of pressure.
Background technology
With China's electrification progress faster, the quality of overhead type catenary property directly determines block of bow collector of electric locomotive
Current carrying quality, so as to affect the speed of service and safety of train.At this stage for the elasticity measurement of contact line is substantially in machine
Kinetic measurement above car, static measurement is in research space state, and a test locomotive is up to ten million, while test is dynamic
State pressure and static state are otherwise varied.Electrified cause have developed rapidly in recent years, but basic theory is relatively backward all the time, related
Research it is delayed, design to contact net, construction generate many detrimental effects.The deviation of contact net static parameter, may
Adverse effect can be brought to bow net dynamic property.Therefore a kind of measuring method of measurement contact net static parameter, Jin Erhe are studied
The lifting force of reason design pantograph is to be badly in need of at present solving the problems, such as and studying.
Overhead type contact net is the main frame of electric railway, is a kind of by electric pole support, is set up in driven by power
Above vehicle travels track in midair, when connection is in contact with it to the power transmission line to its special shape directly powered
Road.With China's electrification progress faster, the quality of overhead type catenary property directly determines receiving for block of bow collector of electric locomotive
Current mass, so as to affect the speed of service and safety of train.Wherein, pantograph is that electric tractor obtains electric energy from contact net
Electrical equipment, on locomotive or motor-car roof.
In train travelling process, always wish that pantograph can be remained with contact line and contact.The lift of increase pantograph
Lift and mitigation pantograph quality can also improve current carrying quality.But it is restricted to increasing pantograph lifting force, increase lifting force
Although can allow pantograph preferably with contact linear contact lay, while the abrasion of pantograph pan and contact line can be accelerated, easily
Increase the metal fatigue of contact line, shorten its life-span.Therefore, pantograph lifting force needs to consider, and Rational choice could be obtained
To optimum efficiency.
Contact net static parameter is the basic guarantee of good bow net dynamic property, and bow net dynamic property is again to limit to list fortune
One of principal element of scanning frequency degree.In construction, operation, maintenance process, the possible off-design ginseng of contact net static parameter causes
Contact line nature static changes, or even hard spot occurs, affects bow net dynamic effects bow net dynamic operation performance.

Specific embodiment
As shown in figure 1, the present invention is the contact line downward pressure measurement apparatus of overhead type contact net, by supporting mechanism, rise
Descending mechanism, measuring mechanism composition, supporting mechanism by the support being placed in the scope of operation, rack-mount strut, be arranged on
Platform composition on strut；Elevating mechanism be arranged on supporting mechanism platform on, elevating mechanism by automatic dead-locking function lifting
Machine and spiral shell type screw mandrel are constituted；Measuring mechanism is arranged on the upper end of elevating mechanism, is made up of sensor, wire clamp, digital displaying push-and-pull tensiometer.
As shown in Figure 1, Figure 2, Figure 3 shows, platform 5 is quadrangle platform, and platform 5 is provided with lift 12 and spiral shell type screw mandrel 7, is passed
Sensor 9 is fixed on spiral shell type screw mandrel 7 by the first bolt 8, and wire clamp 11 is provided with thrust pickup 9, and platform 5 is arranged on and props up
The top of first strut 4 of support mechanism.
As Figure 1 and Figure 4, lift 12 is connected by the second bolt 16 with platform 5, and handwheel 6 is fixed on by worm screw 13
The one end of lift 12, spiral shell type screw mandrel 7 is fixed on lift 12 by worm gear 14.
As shown in Figure 1, shown in Figure 5, thrust pickup 9 is fixed below by the first bolt 8 with spiral shell type screw mandrel 7, and top is by the
Three bolts 10 are fixed with wire clamp 11, and digital displaying push-and-pull tensiometer 15 is connected by the 4th bolt 17 with thrust pickup 9.
As shown in Figure 1 and Figure 2, the platform 5 of the upper end of support 1 is provided with four the second bolts for connecting lift 12
16, platform 5 is arranged on the upper end of the first strut 4, and the first strut 4 and the second strut 18 are fixed by the first embolism 2, the second strut
18 and the 3rd strut 19 fixed by the second embolism 3.
As shown in Figure 1 and Figure 2, support 1 is three-legged support.
As shown in Figure 1 and Figure 2, support 1 is located at bottom, and for supporting whole equipment, the support mainly has two functions, uses
In control device and regulation height, the height of support is designed as 700mm, with support while should put down when screw mandrel base is installed
Together, reserving the locus of hand wheel rotating.The top surface area of support 1 is good with base engagement.The supporting leg of support be it is dismountable,
It is easy to mobile, transport and assembles；And support height is adjustable, the equipment easily higher contact line of measurement can be made.
As Figure 1 and Figure 4, lift 12 is located at the top of support 1, with raising, declines function.The lift is main
It is made up of Worm and screw and handwheel.Worm and screw long service life, operation is smooth, prevents rotation, while also having low wear rate
And the linear motion system of the extremely low moment of resistance, the requirement to power is reduced, select worm screw（Worm gear）Screw mandrel is also as it can be with
By providing pole bigger thrust, longer stroke.The upward pressure that the screw lift can provide 500N with highest, and
Maximum pressure value can at any time be changed according to experiment specific requirement.Meanwhile, this device is also equipped with rule for screw lift, can
It is detachable between Worm and screw and handwheel intuitively to read the height of screw mandrel rising and record, increase device availability.
As shown in figure 3, thrust pickup is located at screw lift top, the effect of current pressure values can be read.This dress
Put the sensor for using and there is high-accuracy high-resolution, 0.5 grade of the degree of accuracy, least count reaches 0.001N, has peak value during reading
Function is kept, keeps peak value to show until resetting manually, while have especially big memory storage function, with 888 test value storages,
It is entirely capable of ensureing experiment demand.Test data can be passed through data by S-232C serial ports output functions, supporting synchronizing software of arranging in pairs or groups
Line input computer obtains test curve figure, and can derive and do various detailed analyses.
As shown in Figure 5, Figure 6, wire clamp 11 plays a part of fixed contact line in whole device top.Will in this device
Wire clamp is designed to U-shaped, internal diameter 500mm, the elasticity of the contact line for being easy to measure various width.
The present invention measurement process be：During measurement, thrust meter outer sensor is fixed on into the top of screw lift, is risen
Drop machine is fixed on again on support, and fixed support base, wire is stuck in the middle of U-shaped wire clamp.Operating personnel put contact line to be measured
To on wire clamp 11, the top of thrust pickup 9 is fixed under wire clamp 11 by the 3rd bolt 10, keeps tripod 1 all the time on ground,
Now pressure is zero, and the height for taking screw mandrel 7 is reference zero, and shake screw lift handwheel 6 is slow to rise thrust pickup 9,
So that the thrust of the test of thrust pickup 9 reaches the lifting force needed for test（40N, 70N, 100N, 130N）, then measure now
The rising value of screw mandrel distance reference zero point, and record.
