Description
Technical field
The utility model relates to detection technique field, particularly a kind of cable power supply plug pick-up unit.
Background technology
World is more and more paid attention to environmental protection, vigorously supports thus various new energy technologies.As a main source of atmospheric pollution, motor vehicle exhaust emission is subject to more and more stricter restriction, begun one's study new-energy automobile obtained the achievement attracting people's attention of Ge great automobile factory commercial city.Electric automobile, as the one of new-energy automobile, has really realized tail gas 0 and discharged, but electric automobile faces more potential safety hazard than orthodox car, must carry out stricter safety monitoring standard.
Charging cable connector is as the requisite parts of electric automobile, belongs to one of essential items for inspection of the electric automobile conduction chargeable connection device that UL2954 specifies, and its security performance is very important.The detection method of charging cable connector is by confession plug and the vehicle plug of the cable of recommending with manufacturer, extracts 3 test specimens, is optionally placed on respectively on concrete floor.Pressure with the orthodox car tire of P225/75R15 or equivalent loads with (5000 ± 250) N, pressed for plug or vehicle plug (inflation pressure of tire (220 ± 10) kPa) with the speed of (8 ± 2) km/h.Before wheel was pressed from test specimen, each test specimen all should be optionally on the ground with normal mode; Test specimen in detection should be without obvious unusual fluctuation; The test specimen that is applied in pressure should not be placed on protrusion.This detection is mainly to simulate domestic consumer when to charging electric vehicle, and random will be placed on floor for plug, and then situation about being rolled by the wheel of vehicle.What this detection was investigated is whether can bear the unconscious of vehicle for the structural strength of plug to roll, and after this detects, its inner dangerous live part and back panel wiring can not be touched by user, can not cause fire and electric shock accidents.Judge the standard whether passed through of detecting, the one, whether inner conductive body is connected with internal wire and exposes also and can touch, and the 2nd, whether likely cause on fire or Danger Electric shock risk.
Since long duration, in made in China and export to the electrical automobile charging plug of the U.S., considered the condition such as authority of detection, safety detection is all that sample is directly delivered to U.S.'s inspection, cause testing cost high, and sense cycle is long, and business burden is larger.And there is following shortcoming in above-mentioned testing process: the one, and inspection is repeatable poor, can not ensure that wheel can be pressed on test specimen at every turn accurately, and uncontrollable wheel rolls the structure weakest part of test specimen accurately; The 2nd, test degree of accuracy is poor, and the speed of car only depends on onboard instruments to show, error ratio is larger; The 3rd, efficiency is lower, at least needs 2 people's operations, thereby and cannot automatically detect the requirement that meets fast detecting; The 4th, occupied ground area is large.
Utility model content
The shortcoming detecting in order to solve above-mentioned electrical automobile charging plug, the utility model proposes a kind of electrical automobile charging plug pick-up unit, and the utility model adopts following technical scheme to solve above-mentioned technical matters:
A kind of electrical automobile charging plug pick-up unit, comprises roll extrusion platform, automotive wheel, slide rail, fixed support, pressure-bearing platform, ac adjustable speed motor and heavy iron, driving mechanism and control box; Described slide rail is fixed on roll extrusion platform both sides, described fixed support is installed on slide rail, described automotive wheel is flexibly connected and is arranged at roll extrusion platform top with fixed support, described ac adjustable speed motor connects driving mechanism, described driving mechanism is connected with fixed support, described control box is electrically connected with ac adjustable speed motor, and described pressure-bearing platform is lifted on roll extrusion platform below and is connected with described fixed support, and described heavy iron is positioned on pressure-bearing platform.
Preferably, in above-mentioned a kind of electrical automobile charging plug pick-up unit, described automotive wheel is flexibly connected with fixed support by bearing.
Preferably, in above-mentioned a kind of electrical automobile charging plug pick-up unit, described driving mechanism is ball screw.
Compared with prior art, the utlity model has following technique effect:
Adopt design of the present utility model, use fixing test unit to replace traditional on-the-ground test, singlely can be high efficiency complete detection operation, and result is accurate, error is less, and sense cycle is short, enterprise is detected without sample is delivered to foreign country, greatly reduces the cost that enterprise is detected; This structure of the detecting device is simple simultaneously, easy to operate, can be suitable for most countries examination criteria by change relevant device parameter, with low cost, takes up room little, is convenient to practicality.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but the utility model is not only confined to following examples.
A kind of electrical automobile charging plug pick-up unit, comprises roll extrusion platform 1, automotive wheel 2, slide rail 3, fixed support 4, pressure-bearing platform 5, ac adjustable speed motor 6, ball screw 7, control box 8, heavy iron 9; Described slide rail 3 is fixed on roll extrusion platform 1 both sides, described fixed support 4 is installed on slide rail 3, described automotive wheel 2 is flexibly connected and is arranged at roll extrusion platform top by bearing with fixed support 4, described ac adjustable speed motor 6 connects ball screw 7, described ball screw 7 is connected with fixed support 4, described control box 8 is electrically connected with ac adjustable speed motor 6, and described pressure-bearing platform 5 is lifted on roll extrusion platform 1 below and is connected with described fixed support 4, real-time being shown on control box 8 panels of rotating speed of motor.
This experimental provision can be by adjusting the requirement of device parameter with coupling various countries' standard testing, the present embodiment is taking the U.S. as example, the specification that the electric automobile conduction chargeable connection device test stone specifying according to UL2954 is set automotive wheel 2 is P225/75R15, tire pressure is 220kpa, loading on by adjustment the pressure that the heavy iron 9 on pressure-bearing platform 5 puts on roll extrusion platform 1 automotive wheel 2 is 5000N, regulate the rotating speed of ac adjustable speed motor 6 by control box 8, the circular-rotation of motor is converted into rectilinear motion by ball screw 7, power is passed to fixed support 4 by ball screw 7, thereby the automotive wheel 2 that promotes to be fixed on fixed support 4 rolled with the speed of 8km/h the test sample being positioned on roll extrusion platform 1 on slide rail 3, then also can touch and whether likely cause on fire or Danger Electric shock risk to determine that whether sample is qualified by checking that test sample inner conductive body is connected with internal wire whether to expose.
Adopt design of the present utility model, use fixing test unit to replace traditional on-the-ground test, singlely can be high efficiency complete detection operation, and result is accurate, error is less, and sense cycle is short, enterprise is detected without sample is delivered to foreign country, greatly reduces the cost that enterprise is detected; This structure of the detecting device is simple simultaneously, easy to operate, can be suitable for most countries examination criteria by change relevant device parameter, with low cost, takes up room little, is convenient to practicality.
