Description

Technical Field

[0001] The present invention relates to the technical field of locomotives, and in particular to an underground new energy and environment-friendly locomotive for mining. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new vehicle power devices), integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include four major types: hybrid electric vehicles (HEV), pure electric vehicles (BEV, including solar vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as supercapacitors, flywheels and other high-efficiency energy storage devices). Unconventional vehicle fuels refer to fuels other than gasoline and diesel. Among them, electric vehicles are mainly powered by electricity. Most vehicles are directly driven by motors. Some vehicles install the motors in the engine compartment, and some directly use wheels as rotors for four motors. The difficulty lies in power storage technology. It does not emit harmful gases that pollute the atmosphere. Even if the power consumption is converted into power plant emissions, except for sulfur and particulate matter, other pollutants are significantly reduced. Since most power plants are built far away from densely populated cities, they are less harmful to humans. Moreover, power plants are fixed and concentrated, so it is easier to remove various harmful emissions, and relevant technologies have been developed. Since electricity can be obtained from a variety of primary energy sources, such as coal, nuclear energy, hydropower, wind power, light, heat, etc., people are no longer worried about the depletion of oil resources. Electric vehicles can also make full use of the surplus electricity during the low electricity consumption in the evening to charge, so that power generation equipment can be fully utilized day and night, greatly improving its economic benefits. Relevant research shows that the same crude oil is refined, sent to power plants to generate electricity, charged into batteries, and then driven by batteries. Its energy utilization efficiency is higher than that of refining crude oil into gasoline and then driven by gasoline engines. Therefore, it is beneficial to save energy and reduce carbon dioxide emissions.

[0003] At the same time, existing technology has used new energy vehicles in mine locomotives to replace the original diesel drive to achieve energy-saving and environmental protection. Mine locomotives refer to electric locomotives used in large factories, mines or mines. Most of them are DC electric locomotives, which transport the mined minerals through locomotives. The mine locomotives are used to pull the mine cars into a train for transportation. The mine locomotive transportation equipment includes locomotives, mine cars and tracks.

The continuous friction is easy to generate sparks, and the sparks are very likely to catch fire and explode when they come into contact with the coal dust in the air, which may cause the mine to collapse and affect the safety of the mine workers. To solve this problem, a new energy and environmentally friendly locomotive for underground mining is first designed. Summary of the invention

The temperature of the water is lowered by liquid nitrogen, and the water is sprayed onto the surface of the driving wheel through the nozzle. The temperature of the driving wheel is lowered by water. The invention can eliminate the hidden danger of sparks generated by the friction between the locomotive and the track during operation, avoid accidents, and use the existing environmental resources to cool it down, avoid using other water sources to cool the drive wheels, increase the use of resources, and the cooling process will not cause harm to the environment.

The existing environmental resources are used to cool it down, avoiding the use of other water sources to cool the driving wheel 4, increasing the use of resources, and the cooling process will not cause harm to the environment. It can also improve the mine environment and process the coal dust floating in the air, thereby achieving the purpose of energy saving and environmental protection, thereby solving the problem that during the existing locomotive contacting the track, the wheels and the track continue to rub, sparks are easily generated as the temperature rises, and the sparks are very likely to explode when they come into contact with the coal dust in the air.

[0051] Working principle:

[0052] The temperature of the surface of the driving wheel 4 during the operation of the driving wheel 4 and the track is detected by the temperature sensor. The temperature sensor is electrically connected to all the live devices. After detecting that the temperature of one row of driving wheels 4 rises beyond the set range, the corresponding first motor 22 is driven to be turned off by the temperature sensor, so that the driving wheel 4 stops rotating. At the same time, the second hydraulic cylinder 25 retracts to drive the two limit rods 26 to move to the two ends of the driving box 5 respectively, and drives the anti-rocking plate 27 to move along the limit groove 18 and both ends of the anti-rocking plate 27 leave the mounting shaft 19. After the mounting shaft 19 loses the squeezing and limiting of the anti-rocking plate 27, the first hydraulic cylinder 14 retracts to drive the driving rod 16 to slide along the groove 15, and drives the driving box 5 and the driving The movable rod 16 moves along the trajectory, driving the anti-rocking plate 27 to move in the moving direction of the driving rod 16, so that one of the anti-rocking plates 27 is located above the mounting shaft 19 again, and one of the mounting shafts 19 is fixed to one end of the fixing frame 3. The driving rod 16 moves toward the other end of the fixing frame 3, and the rack 17 at one end thereof is meshed with the first gear 21 for transmission. The rotation of the first gear 21 drives one of the mounting shafts 19 to rotate, and the other mounting shaft 19 is connected through the connecting shaft 20 and deflected along the central axis of the first gear 21, so that the mounting shaft 19 not supported by the anti-rocking plate 27 is tilted, and the driving wheel 4 is driven to leave the track, so as to prevent the driving wheel 4 with excessive temperature from continuing to run with the track and generating sparks in the grinding groove;

[0053] At the same time, the second motor 34 drives the second gear 33 to rotate, and the second gear 33 and the toothed disc 9 are meshed and transmitted, thereby driving the slider 30 to move along the track of the slide groove 10. During the movement, the first brake column 32 moves along the side track of the second brake column 35, so that the second brake column 35 drives the lifting shaft 37 to move up and down, and drives the lifting shaft 37 to move downward, thereby driving the driving shaft 7 to move downward, so that the supporting wheel 8 contacts the ground, replaces the driving wheel 4 to run, and drives the vehicle body 1 to move and drives the supporting wheel 8 to rotate through the power of the other driving wheels 4.

[0054] At this time, the driving wheel 4 that has been lifted up due to excessive temperature is just located below the nozzle 41. Since the air humidity in the mine is high, moisture in the air is taken through a sponge. After the sponge is saturated, condensed water droplets fall into the storage box 11 through the filter plate 12. The temperature of the water is lowered by liquid nitrogen, and the third motor 42 drives the cover plate 43 to rotate to separate the cover plate 43 from the nozzle 41. Water is sprayed onto the surface of the driving wheel 4 through the nozzle 41, and the temperature of the driving wheel 4 is lowered by the water. After the temperature is lowered, the driving transmission wheel, the cover plate 43, and the supporting wheel 8 are reset after being detected by the temperature sensor, thereby eliminating the hidden danger of sparks generated by the friction between the locomotive and the track during operation and avoiding accidents.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
