Description
Technical field
The utility model belongs to train accessory equipment, especially train braking apparatus, specifically train braking auxiliary device.
Background technology
Train is the class vehicle that people extremely commonly use, and China because of population more, large small city is also more, and distance between each city is all shorter, and some small towns of a lot of train process also can be stayed to some extent, therefore in road, train acceleration-deceleration is more frequent, the brake gear of current train belongs to Pneumatic brake Guan Weizhu, and for the more train of docking station, its position of stopping all is difficult to realize accurately, due to the restriction of brake system and antilock reason of waiting indefinitely thereof, two cannot accelerate excessive between nearer website, to prevent station inside brake difficulty, and braking procedure is unstable, manual braking once, train is not only easily made to produce concussion, and easily because of the difference of the acceleration/accel that brakes, to cause occupant to fall injured.
Summary of the invention
For solving the problem, the utility model proposes and a kind ofly improve stop position accuracy, promote the speed of a motor vehicle between close website and improve the train braking auxiliary device of braking procedure stability, its concrete technical scheme is as follows:
Train braking auxiliary device, comprise two stabilizing brackets be fixed on bottom train railway carriage, the position of described two stabilizing brackets is relative with two rails respectively, electromagnet is fixed with in stabilizing bracket, the power input of electromagnet is connected with headstock power supply, is connected with manual start and stop valve between electromagnet and power supply.
Described stabilizing bracket adopts stainless steel material to make.
Regulating current device is connected with between described electromagnet and power supply, described regulating current device comprises voltage transformer that input end is connected with power supply and the current relay that input end is connected with voltage transformer, the mouth of current relay is connected with motor switch, and the mouth of motor switch is connected with manual start and stop valve.
The control input end of described voltage transformer, current relay and motor switch is connected with the control output end of controller respectively, and the control input end of controller is connected with adjustment operation plate.
The beneficial effects of the utility model: in brake process, after electromagnet energising and rail produce magnetic force and react, and then the pulling force produced between train and rail, and then when strengthening brake, friction force between train and rail, because this power is magnetic force effect, and there is the effect of train and rail being strained, therefore this process stability is high, not easily rock, stabilizing bracket is steel, therefore the effect of electromagnet absorption rail can not be affected, adjustment operation plate is utilized to regulate voltage transformer by controller, the start and stop of current relay and motor switch, thus determine whether open magnetic force reaction, and the size of regulation output electric current, thus control the magnetic force size of electromagnet, and then the friction force between adjustment train and rail, due to the friction force strengthened between how many trains and rail can be regulated, therefore make stop position accuracy higher, and facilitate the dynamics of brake, and then virtually can improve the speed of a motor vehicle between close website and braking procedure good stability, operation and easy to use and practical.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is train railway carriage bottom construction schematic diagram;
Fig. 3 is the utility model circuit catenation principle figure.
In figure: 1-train railway carriage, 2-stabilizing bracket, 3-rail, 4-electromagnet.
Detailed description of the invention
For the ease of understanding, be further illustrated below in conjunction with Fig. 1-3 pairs of the utility model:
Embodiment 1: train braking auxiliary device, comprise two stabilizing brackets 2 be fixed on bottom train railway carriage 1, stabilizing bracket 2 is for firm electromagnet 4; The position of described two stabilizing brackets 2 is relative with two rails 3 respectively, so that electromagnet 4 better produces magnetic attraction to rail; Be fixed with electromagnet 4 in stabilizing bracket 2, the power input of electromagnet 4 is connected with the power supply in headstock, for providing electric power for electromagnet 4; Manual start and stop valve is connected with, so that hand off power supply where necessary between electromagnet 4 and power supply.
Embodiment 2: described stabilizing bracket 2 adopts stainless steel material to make, has an impact to prevent the magnetic force of stabilizing bracket 2 pairs of electromagnet 4.
Embodiment 3: be connected with regulating current device between described electromagnet 4 and power supply, for regulating the size of electric current; Described regulating current device comprises voltage transformer that input end is connected with power supply and the current relay that input end is connected with voltage transformer, so that regulating voltage and adjustment electric current; The mouth of current relay is connected with motor switch, and motor switch is used for, start and stop disconnected by connecing of electric wire remote-control apparatus; The mouth of motor switch is connected with manual start and stop valve, affecting in the iron core of electromagnet, the number of turn and size of current factor, there is the size of no current and electric current most important, therefore, magnetic force is regulated by regulating the size of electric current, can better reach the effect that equipment is effectively controlled, strengthen the stability of car body in control process.
Embodiment 4: further, the control input end of described voltage transformer, current relay and motor switch is connected with the control output end of controller respectively, the control input end of controller is connected with adjustment operation plate, namely by integrated circuit and the electric power circuit of controller inside, better reach the effect of remote adjustment and each equipment of control, with user-friendly.
Beneficial effect: stop position accuracy is higher, and facilitate the dynamics of brake, and then virtually can improve the speed of a motor vehicle between close website and braking procedure good stability, operation and easy to use and practical.
