Description
Technical field
The utility model relates to electromagnet technical field, in particular, relates to a kind of continuous duty locomotive gate electromagnet.
Background technology
Along with the development of track traffic, traffic safety also more and more comes into one's own.Particularly the security requirement of locomotive door Ore-controlling Role is more and more higher.In order to meet the needs of fail safe, the electromagnet structure in locomotive door Ore-controlling Role requires to turn to continuous duty by discontinuous operation system.In order to meet the requirement of continuous duty, electromagnet structure becomes twin coil work from unicoil.During general twin coil work, coil switches employing and first disconnects the working method connected afterwards, when coil switches, electromagnet there will be moment dead electricity, misoperation or output error signal can be there is in electromagnet when dead electricity, whole system is run and causes interference, even make system occur reporting to the police, influential system normally runs.Meanwhile, owing to needing larger power stage during in order to ensure electromagnet initial adhesive, the power of electromagnet is high, and energy consumption is high.In addition, running part (mandrel) in electromagnet is partly expose mode, conventional oil lubricating system, will inevitably cause that lubricating oil evaporates totally, lubricating oil sticks dust impurity after Long-Time Service, thus certain influence is caused to the suction-combining force of electromagnet, also increase working service cost.
Utility model content
The purpose of this utility model is the technological deficiency for existing in prior art, and provides a kind of energy consumption low, safe and reliable continuous duty locomotive gate electromagnet.
The technical scheme adopted for realizing the purpose of this utility model is:
A kind of energy-saving continuous duty locomotive gate electromagnet, comprise shell, high-power pull-in winding, maintain ancillary coil, mandrel, plectrum and sensitive switch, described high-power coil and the series connection of maintenance ancillary coil are placed in described shell, and be connected with both ends of power, described mandrel is placed in the described high-power coil that is connected in series and maintains in ancillary coil, described mandrel is partly expose, one end that described mandrel exposes is installed with described plectrum, with on the shell of described plectrum opposite position, described sensitive switch is installed, the common port pin of described sensitive switch is connected to described high-power coil and maintains ancillary coil joint, the normal-closed end pin of described sensitive switch is connected with described power supply one end with after the parallel connection of described maintenance ancillary coil, the open end pin of described sensitive switch is empty.
In described mandrel axle sleeve, polymer film is installed.
Described plectrum is J shape.
Compared with prior art, the beneficial effects of the utility model are:
1, electromagnet of the present utility model has energy-conservation feature: electromagnet of the present utility model adopts high-power pull-in winding to be connected in series mode with maintenance ancillary coil, and by with the coordinating of sensitive switch, high-power pull-in winding be high-power output for the initial adhesive of electromagnet, two coils connected in series are that small-power exports for maintaining after electromagnetic actuation.The electromagnetic actuation time is generally about 0.2S, is maximumly generally no more than 0.5S, because this type work of electromagnet is made as continuous duty, so adhesive power can be ignored when rated output, generally press operating power calculating.As can be seen here, this product is than similar-type products at least energy-conservation more than 50%.
2, electromagnet of the present utility model has automated power translation function: electromagnet of the present utility model adopts twin coil tap mode, coordinate sensitive switch, rely on electromagnet self the suction-combining force to touch sensitive switch, to reach the object of coil conversion, achieve automated power conversion, reliability is high.
3, electromagnet of the present utility model not dead electricity in power conversion process: electromagnet of the present utility model adopts twin coil tap mode, maintain ancillary coil during high-power adhesive and be in the state be shorted, be coils connected in series mode during small-power work, thus avoid the instantaneous dead electricity phenomenon of electromagnet, improve reliability and the fail safe of product.
4, electromagnet of the present utility model is oil-free lubrication: electromagnet of the present utility model increases polymer film in mandrel axle sleeve, polymer film acid and alkali-resistance, high temperature resistant, weather, coefficient of friction are extremely low, thus solve the lubrication problem of product, improve the reliability of use.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The schematic diagram of the utility model energy-saving continuous duty locomotive gate electromagnet as Figure 1-Figure 4, comprise shell 1, high-power pull-in winding L1, maintain ancillary coil L2, mandrel 2, plectrum 3 and sensitive switch K, described high-power coil L1 and maintenance ancillary coil L2 series connection are placed in described shell 1, and be connected with both ends of power, described mandrel 2 is placed in the described high-power coil L1 that is connected in series and maintains in ancillary coil L2, described mandrel 2 is partly expose, one end that described mandrel 2 exposes is installed with described plectrum 3, with on the shell 1 of described plectrum 3 opposite position, described sensitive switch K is installed, common port (COM) pin of described sensitive switch K is connected to described high-power coil L1 and maintains ancillary coil L2 joint, normal-closed end (NC) pin of described sensitive switch K is connected with described power supply one end with after described maintenance ancillary coil L2 parallel connection, open end (NO) pin of described sensitive switch K is empty.
In order to realize oil-free lubrication, in described mandrel 2 axle sleeve, polymer film 4 is installed.
For the ease of work, described plectrum 3 is J shape.
Under non-"on" position, maintain ancillary coil L2 be in the state be shorted.When energized, be in owing to maintaining ancillary coil L2 the state be shorted, only have high-power pull-in winding L1 in running order, now, electromagnet is in the high-power adhesive stage.Mandrel 2 drives plectrum 3 setting in motion.When mandrel 2 moves to close to complete attracted position, mandrel 2 drives switch plectrum 3 to touch sensitive switch K, and the normal-closed end of sensitive switch is opened, and maintains ancillary coil L2 short-circuit condition and is destroyed, maintain ancillary coil L2 and high-power pull-in winding L1 tandem working, electromagnet completes power transfer.Now, electromagnet by high-power adhesive phase transition to the small-power maintenance stage.Mandrel 2 continues to move to complete attracted position.
Electromagnet of the present utility model passes through the reasonable combination of two coils and sensitive switch, reaches energy-conservation object, meanwhile, improves the reliability of product, ensured the operation that locomotive door Ore-controlling Role is safe and reliable.Meanwhile, oil-free lubrication is achieved.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
