Abstract
The utility model belongs to the technical field of track locomotive energy -saving equipment technique and specifically relates to an arresting gear is retrieved to subway kinetic energy. An arresting gear is retrieved to subway kinetic energy, includes track, train and transmission line, and the bottom and the top of train are connected with track and transmission line respectively, are equipped with dc -to -ac converter, motor, screw and braked wheel on the train, and the motor has two, is connected with screw and braked wheel respectively. During the use, electric energy that train braking produced is direct to be transmitted for two motors through the dc -to -ac converter, and the motor drive screw on upper portion is rotatory, produces prorsad air current, with the opposite direction that traveles of train, forms the resistance braking, and the protection casing on the screw plays the safety protection effect, and the motor drive braked wheel of lower part is rotatory, with the rotatory opposite direction of train wheel, plays auxiliary brake and acts on to it is used that the electric energy that produces train braking directly is this train, has strengthened braking effect.
Description
Technical field
The utility model relates to rail locomotive energy-saving equipment technical field, especially a kind of subway recover kinetic energy brake equipment.
Background technology
Along with city traffic is day by day flourishing, urban rail transit construction develops rapidly, and the traffic such as subway, track becomes the important vehicle in large and medium-sized city.Particularity due to its operation characteristic of city traffic is exactly that running velocity is fast, start, brake frequently, and a large amount of energy can be produced during braking, in order to reclaim this part energy, inversion feedback mode is generally adopted to install an inverter at present between the DC bus and protective cover of traction substation, unnecessary regenerating braking energy inversion is fed back in protective cover, could by other equipment utilizations but a larger circulation is done in this part energy demand, and cannot directly by this locomotive trans-utilization, inefficiency.
Utility model content
Slow in order to overcome the circulation of existing locomotive recover kinetic energy, the deficiency of inefficiency, the utility model provides a kind of subway recover kinetic energy brake equipment.
The utility model solves the technical scheme that its technical matters adopts: a kind of subway recover kinetic energy brake equipment, comprise track, train and transmission line of electricity, the bottom of train is connected with track and transmission line of electricity respectively with top, train is provided with inverter, motor, screw propeller and brake wheel, motor has two, is connected respectively with screw propeller and brake wheel.
According to another embodiment of the present utility model, comprise further, motor is connected with the braking circuit of train by inverter.
According to another embodiment of the present utility model, comprise further, screw propeller and brake wheel are arranged on front end and the bottom of train respectively.
According to another embodiment of the present utility model, comprise further, screw propeller is provided with protective cover.
The beneficial effects of the utility model are, arrange two motors ON TRAINS, and on two motors, connect screw propeller and brake wheel respectively.During use; the electric energy that train braking produces directly is transferred to two motors by inverter, and the motor on top drives screw propeller to rotate, and produces air-flow forward; contrary with the travel direction of train; form friction brakes, the protective cover on screw propeller plays safety guard-safeguard effect, and the motor of bottom drives brake wheel to rotate; contrary with the hand of rotation of train wheel; play brake assisting effect, thus the electric energy produced by train braking is directly that this train is used, enhances braking effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure 1, track, 2, train, 3, transmission line of electricity, 4, inverter, 5, motor, 6, screw propeller, 7, brake wheel, 8, protective cover.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of subway recover kinetic energy brake equipment, comprise track 1, train 2 and transmission line of electricity 3, the bottom of train 2 is connected with track 1 and transmission line of electricity 3 respectively with top, train 2 is provided with inverter 4, motor 5, screw propeller 6 and brake wheel 7, motor 5 has two, is connected respectively with screw propeller 6 and brake wheel 7.Motor 5 is connected with the braking circuit of train 2 by inverter 4.Screw propeller 6 and brake wheel 7 are arranged on front end and the bottom of train 2 respectively.Screw propeller 6 is provided with protective cover 8.
Train 2 arranges two motors 5, and on two motors 5, connects screw propeller 6 and brake wheel 7 respectively.During use; the electric energy that train braking produces directly is transferred to two motors 5 by inverter 4, and the motor 5 on top drives screw propeller 6 to rotate, and produces air-flow forward; contrary with the travel direction of train 2; form friction brakes, the protective cover 8 on screw propeller 6 plays safety guard-safeguard effect, and the motor 5 of bottom drives brake wheel 7 to rotate; contrary with the hand of rotation of train 2 wheel; play brake assisting effect, thus electric energy train 2 being braked generation is directly that this train is used, enhances braking effect.
