Description
Technical field
The mandatory experiment of metro pantograph type approval test is the utility model is related to, particularly a kind of pantograph lateral stiffness is surveyed
Measure device.
Background technology
《IEC--60494-2--2013 railway applications-vehicle pantograph：Characteristic and experiment -- part 2 -- subway and light
Rail pantograph》Standard is on requiring measurement lateral stiffness value, its measurement request in the mandatory experiment of pantograph type approval test：
When pantograph should rise to highest working depth E, when supporting every side of frame part of bow to apply 300N power in succession, per side
Certain numerical value is not to be exceeded in displacement：That is rising bow height E<2m, the ultimate range of disalignment is 20mm；2m≤E<3m, partially
Ultimate range from center line is 30m；E >=3m, the ultimate range of disalignment is 40mm.
It is connected and measures with bow by rope using man-hour manually hand-held spring tension meter at present, passes through spring tension meter
Apply 300N pulling force to bow and measure the off-center displacement of bow.This mode measurement result precision is low, and artificial behaviour
Work can not ensure that force direction is accurate, and displacement is judged completely by worker's measured value.
Utility model content
The purpose of this utility model is：For above-mentioned problem, there is provided a kind of suitable metro operation vehicle overhauling storehouse
It is interior, portable, facilitate installing/dismounting and the high pantograph lateral stiffness measurement apparatus of measurement accuracy.
To achieve the above object, the utility model provides a kind of metro pantograph lateral stiffness measurement apparatus, and its feature exists
In：Including main body rack, laser displacement sensor, standard test weight, steel cable component, locating wheel；Laser displacement sensor, standard weight
Code is arranged on main body rack, and the laser displacement sensor is used for measuring pantograph collector head shift length；Steel cable component one end
It is fixed in pantograph collector head rotating shaft, the other end hangs nominal counterweight around locating wheel, and pantograph framework and main body rack pass through horizontal stroke
It is fixedly connected to connection component.
Using above-mentioned technical proposal, the beneficial effects of the utility model are：
1st, the utility model can accurately, quickly measure pantograph lateral displacement data, and measurement data is accurately and reliably.
2nd, the utility model convenient and swift can be installed, and it is laterally firm to pantograph to be suitable for runing foundation in vehicle overhauling storehouse
Spend cyclically-varying data sheet, convenient maintenance and maintenance.
Brief description of the drawings
Fig. 1 is the utility model embodiment schematic diagram.
Embodiment
As shown in figure 1, lateral stiffness measurement apparatus of the present utility model is by nominal counterweight 1（300N）, it is steel cable component 2, fixed
Position wheel 3, main body rack 4, transversal connecting assembly 5, laser displacement sensor 6 form.
The main body rack 4 is measurement apparatus main body, above stationary positioned wheel 3 and laser displacement sensor 6；The steel cable
Component 2 is that one end is fixed in pantograph collector head rotating shaft, and the other end hangs nominal counterweight（300N）, it forms one around locating wheel 3
The mechanism of individual measurement lateral pull；Laser displacement sensor 6 is integrally fixed on main body rack 4, it measure pantograph collector head by
During 300N cross forces, bow offset；The transversal connecting assembly 5 connects pantograph framework and main body rack, ensures nominal weight
Code 1（300N）, steel cable component 2, locating wheel 3, main body rack 4, laser displacement sensor 6 form measurement apparatus can be fastened on
On pantograph framework, make measurement data precisely reliable.
