Description

A kind of pantograph pressure experimental device
Technical field
Pressure experimental device is the utility model is related to, more particularly to a kind of pantograph pressure experimental device.
Background technology
Rail vehicle electric locomotive is to obtain electric energy from contact net to drive traction electric machine to run by pantograph, because This, the performance quality of pantograph directly affects the reliability of operation power.During train high-speed cruising, pantograph and contact line it Between to maintain suitable contact.When contact is too small, easily causes offline and produce arcing, when contact is excessive When, contact line Uplifting amount is excessive, makes contact line local buckling and causes fatigue damage, while also causes between contact line and slide plate Abrasion are increased, and accident between pantograph can be also caused when serious, influences the safe operation of electric locomotive.
Existing contact typically measures the contact of pantograph using spring scale.Contact is surveyed using spring scale When, it is necessary to pulling at the uniform velocity, can be influenceed during this by many human factors (power, the speed that such as pull), therefore measure Parameter unavoidable have certain error.The existing technical scheme that current collecting bow lifting pull weight is measured using motor, its Cost is larger, and measurement process is complex, is unfavorable for the reduction of enterprise's manufacturing cost.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of pantograph pressure experimental device.The utility model Device using linkage levelling screw to horizontal stand carry out leveling, it is ensured that reference plane is consistent residing for pantograph in test process, improve The accuracy of pressure test structure, dress of the present utility model are easy to adjust the excellent of pantograph pan and pressure sensor contacts points Point, have the characteristics that simple installation, cost are cheap.
The technical solution of the utility model is:A kind of pantograph pressure experimental device, including pressure sensor, mounting rod, Horizontal stand, workbench, fixing bolt, adjustment hole, adjusting rod, pantograph place block, linkage levelling screw, fix on horizontal stand four by Pantograph places block, and adjusting rod is fixedly mounted in horizontal stand side, it is characterised in that:Described horizontal stand is fixed on by linkage levelling screw On workbench, multiple adjustment holes are set, " L " shape is integrally presented in described mounting rod, and mounting rod passes through solid on described adjusting rod Surely it is bolted on adjusting rod, Gu installation pressure sensor on the downside of mounting rod cross bar;Described pantograph, which places block, includes cone Shape fixed station, boss, fixed block, fixed block are arranged on the both sides of boss, and the top of boss sets taper fixed station.
According to pantograph pressure experimental device as described above, it is characterised in that:Also include tester, described pressure passes Connected between sensor and tester with wire.
According to pantograph pressure experimental device as described above, it is characterised in that:Described adjustment hole is four.
According to pantograph pressure experimental device as described above, it is characterised in that:Described taper fixed station be from it is upper it Under the pyramidal structure that becomes larger.
According to pantograph pressure experimental device as described above, it is characterised in that:Described taper fixed station uses rubber Material.
The beneficial effects of the utility model are:First, the levelness of test platform is high, make test value more accurate;Second, just In regulation, can be finely adjusted with butt contact position;Third, tested pantograph can be protected, its paint is set not to be scratched; Fourth, simple in construction, manufacturing cost, use cost are all very cheap.
Brief description of the drawings

Fig. 2 is the structural representation that pantograph places block;
Description of reference numerals:Pressure sensor 1, mounting rod 2, horizontal stand 3, workbench 4, fixing bolt 5, adjustment hole 6, tune Pole 7, tester 8, pantograph place block 9, taper fixed station 91, boss 92, fixed block 93, linkage levelling screw 10.
Embodiment
The technical solution of the utility model is described further below in conjunction with accompanying drawing.
As shown in figure 1, pantograph pressure experimental device of the present utility model includes pressure sensor 1, mounting rod 2, level Platform 3, workbench 4, fixing bolt 5, adjustment hole 6, adjusting rod 7, tester 8, pantograph place block 9, linkage levelling screw 10.Horizontal stand 3 are fixed on workbench 4 by linkage levelling screw 10.During due to device experiment of the present utility model, therefore, to assure that the water of horizontal stand 3 Flat precision, within preferably up to 0.1 °, when so may insure experiment, shape when pantograph pan contacts with pressure sensor 1 State, make test value more accurate.And before the present apparatus can work, place the water of horizon sensor measuring table in horizontal stand 3 Pingdu, and by finely tuning linkage levelling screw 10, make the levelness of horizontal stand 3 within 0.1 °.4 structure phases are fixed on horizontal stand 3 Same pantograph places block 9, and pantograph places block 9 and tests pantograph used for placing.The also fixed peace in the side of horizontal stand 3 Adjustment pole 7, multiple adjustment holes 6 are set on adjusting rod 7.Mounting rod 2 is overall to be presented " L " shape, and mounting rod 2 passes through fixing bolt 5 It is connected on adjusting rod 7, and installation pressure sensor 1 on the downside of the cross bar of mounting rod 2, with leading between pressure sensor 1 and tester 8 Line connects.Because adjusting rod 7 of the present utility model is provided with multiple adjustment holes 6, make the utility model mounting rod 2 and adjusting rod 7 Overall height can carry out the regulation of height, adjustment hole of the present utility model by the way that mounting rod 2 is fixed in different adjustment holes 6 6 can be four.Mounting rod 2 of the present utility model can also be in the internal rotation of adjusting rod 7, so as to be tested according to pantograph simultaneously It is required that difference, select the difference of pantograph pan to be contacted with pressure sensor 1.
As shown in Fig. 2 the utility model pantograph, which places block 9, includes taper fixed station 91, boss 92, fixed block 93, Gu Determine block 93 to be used to pantograph placement block 9 being integrally attached to horizontal stand 3, fixed block 93 is arranged on the both sides of boss 92, boss 92 top sets taper fixed station 91.Boss 92 of the present utility model is set, and is made between the pantograph after placement and horizontal stand 3 With enough spaces, the power supply of connection pantograph during can conveniently testing.As shown in Fig. 2 taper fixed station 91 be from The pyramidal structure become larger under upper, when being so easy to pantograph test, pantograph is placed on four pantographs and places block 9, need not be fixed during experiment, you can start to test, also can be very easily from testing stand by pantograph after experiment Take out.Because the effect of taper fixed station 91 of the present utility model is position-limiting action, it need not be fixed, therefore taper fixed station 91 Material is preferably elastomeric material, can so protect tested pantograph, its paint is not scratched.
The course of work of the present utility model is:Horizontal stand 3 is adjusted to by horizontality by linkage levelling screw 10 first, then will Pantograph be placed on pantograph place block 9 it is fast on, pantograph rises, and pantograph pan is contacted with pressure sensor 1, passes through survey Try instrument 8 and show contact, and then judge whether contact meets the requirements.During experiment, fixing bolt can be passed through 5th, adjustment hole 6 finely tunes height and the position of pressure sensor 1, it is met the test of different type pantograph.
