For achieving the above object, the technical scheme that the utility model adopts is:
A kind of electric power safety helmet proving installation, the utility model is characterised in that: comprise pole, be welded on the round stake of pole top sidewall, electromagnet and base, pole bottom welding is on base, and four rolling is equipped with in the bottom surface of base; Described electromagnet is fixed on direction in round stake and, adsorbs auxiliary weight during for being energized down; Described base is equipped with sensor, and be fixed for the head mould placing safety helmet to be measured above sensor, described head mould is positioned at immediately below electromagnet.
Pole described in the utility model is rolled into divergent-cone wall by the iron plate of 1.5mm ~ 3mm, and basal diameter is 400mm ~ 500mm, and top diameter is 250mm ~ 300mm, is highly 1450mm ~ 1550mm.
The auxiliary weight that electromagnet described in the utility model adsorbs is iron hammer for testing or steel pricker.
Dog screw is all equipped with in four angles of the utility model below described base, can regulate four screw dog screws that device can be placed stably, be convenient to test on irregular ground.
Principle of work of the present utility model is: utilize safety helmet test macro to carry out impulse test and the puncture test of safety helmet respectively.The steel hammer of 5kg is adopted during impulse test, steel hammer material is 45# steel, steel hammer is placed in the height on distance 1 meter, safety helmet top, allows steel hammer do the movement of falling object, if steel hammer drops on impulsive force suffered on safety helmet be less than 4900N and well-tended appearance, then safety helmet is qualified, so we utilize the height of pole 1500 about mm, pole is installed a circle stake, and electromagnet is installed in circle stake, and install head mould immediately below electromagnet, head mould is arranged on 20KN sensor, for makeing the device of safety helmet test, when the solenoid is energized, above steel hammer is adsorbed on, safety helmet is buckled on head mould simultaneously, now safety helmet is 1 meter to the distance of steel hammer end, the circuit of tripping magnet again, weight is doing freely falling body from the position of safety helmet 1 meter, weight pounds the center at safety helmet, now can according to sensor record maximum impact force now, the impulsive force measured is done inside with 4900N and is compared by system, if the impulsive force of testing is greater than 4900N, then test is for defective, if the impulsive force of testing is less than 4900N, crack etc. whether is had to determine that whether this safety helmet is qualified according to safety helmet outward appearance.Adopt the steel pricker of 3KG during puncture test, test method is steel pricker is placed in the height of 1 meter, and allow steel pricker do the movement of falling object, if steel pricker head pierces through safety helmet and touches on head mould, then safety helmet is defective, if do not puncture, is then qualified.
Compared with prior art, the utility model has the following advantages: simple and compact for structure, production cost is low, test process is quite convenient, the wheel of high strength being housed below the base plate of proving installation, can being easy to when usually needing to move position mobile, at four angles of base, screw locating device is installed simultaneously, can regulate four positioning screws that device can be placed stably in the irregular situation in present ground, be convenient to test.
