Abstract
The utility model discloses a device which can enhance the wheel track adhesive force. The device comprises a valve (12) and an air jetting unit (15). The air jetting unit (15) is equipped with at least an air exhausting hole (16); the valve (12) is respectively connected with a chief air cylinder (11) and the air jetting unit (15). The utility model blows and sweeps a heated high pressure draft to the track surface to ensure the aggregating speed to be reduced, thus the wheel track adhesive force is enhanced, and during the rain and snow weather, the loose running of the locomotive wheel can be prevented effectively.
Description
Technical field
The utility model relates to railway art, especially relates to a kind of device that increases wheel rail adhesion power.
Background technology
Along with the development of railway transportation high-speed overload, require locomotive that enough big tractive force is arranged, to realize that Duola hurries up.And rail and wheel to adhesion strength be limited, in case tractive force surpasses the adhesion strength between wheel track, just will inevitably cause idle running.The generation of idle running sharply descends the tractive force on the driving wheel, simultaneously rail with take turns between owing to violent friction produces serious damage.
At present, adopt the mode of stucco to improve wheel rail adhesion power usually, with the idle running that prevents that locomotive wheel is right.Sand is exactly the sand of river bank, but after will passing through the screening and oven dry of locomotive depot, just loads onto locomotive, and its effect is to improve the adhesion condition, increases the friction factor of rail tread.Generally at the starting train; The heavy haul train climbing; Weather sprinkles; During the situation of a series of easy generations idle running such as train brake hard, all prevent locomotive wheel spin by stucco.Six locomotives generally have eight sandboxes, 0.1 cubic metre of each sandbox volume, and full car is the sand amount about a ton approximately.
But, when sleety weather,, wheel rail adhesion power is reduced because sleet is lubricated, just, can't prevent the idle running that locomotive wheel is right fully by the mode of stucco.
The utility model content
The utility model provides a kind of device that increases wheel rail adhesion power, can overcome the defective that reduces to cause the locomotive wheel pair idling in the prior art at sleety weather owing to wheel rail adhesion power.
For achieving the above object, the utility model provides a kind of device that increases wheel rail adhesion power, comprises valve (12) and air injection unit (15), and described air injection unit (15) has at least one steam vent (16); Described valve (12) is connected with described air injection unit (15) with total reservoir (11) respectively.
According to an aspect of the present utility model, also comprise non retern valve (13) and heating unit (14), the anode of described non retern valve (13) is connected with described valve (12), and the contrary end of described non retern valve (13) is connected with described air injection unit (15).
According to another aspect of the present utility model, described heating unit (14) is an electrothermal tube.
According to another aspect of the present utility model, described air injection unit (16) is fixed on the sandbox inboard, and its steam vent (16) is parallel to rail and is higher than rail level 2-4 centimetre.
According to another aspect of the present utility model, connect by tracheae between the each several part of described device.
The technical solution of the utility model has the following advantages at least:
The utility model will purge to rail level through the high pressure draught of heating, the rainwater of rail level, snow-broth is reduced rapidly, thereby increased wheel rail adhesion power, when sleety weather, also can effectively prevent the idle running that locomotive wheel is right.
Description of drawings
Fig. 1 is a kind of structure chart that increases the device of wheel rail adhesion power of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail:
The utility model embodiment a kind of increase wheel rail adhesion power device structure as shown in Figure 1, comprise total reservoir (11), valve (12), non retern valve (13), heating unit (14) and air injection unit (15), wherein valve (12) is connected with the anode of total reservoir (11) with non retern valve (13) respectively, and heating unit (14) is connected with air injection unit (15) with the contrary end of non retern valve (13) respectively; Air injection unit (15) has a plurality of steam vents (16).
Total reservoir (11) sends to air injection unit (15) with high-pressure blast by valve (12), non retern valve (13) and heating unit (14), the steam vent (16) of this high-pressure blast by air injection unit (15) face toward orbital plane from inside to outside, purging forward.Valve (12) is used to control the conveying of high-pressure blast, and when opening valve (12), high-pressure blast is transported to air injection unit (15) by total reservoir (11), and valve-off (12) then ends the conveying of high-pressure blast.Heating unit (14) increases the purging energy of high-pressure blast by high-pressure blast is heated; In order to prevent heating owing to heating unit (14), the pressure of high-pressure blast is increased, and cause the reverse flow of high-pressure blast, add non retern valve (13) at valve (12) and heating unit (14), stop the reverse flow of high-pressure blast.
In the present embodiment, it is 12 centimetres steel pipe that air injection unit (15) adopts a diameter, and this steel pipe is welded in the sandbox inboard, makes its termination be about 70 centimetres partial parallel in rail and be higher than rail level 2-4 centimetre.Some apertures are evenly beaten as steam vent (16) in termination 70 centimetres of steel pipes, make aperture face toward orbital plane and purge high-pressure blast from inside to outside, forward.The electrothermal tube that 220V, 1000W are housed in the pipe between non retern valve (13) and aperture in order to high-pressure blast is heated, increases the purging energy of high-pressure blast as heating unit (14).High-pressure blast is provided by total reservoir (11), and the power supply of electrothermal tube is provided by locomotive.
The utility model will purge to rail level through the high pressure draught of heating, the rainwater of rail level, snow-broth is reduced rapidly, thereby increased wheel rail adhesion power, when sleety weather, also can effectively prevent the idle running that locomotive wheel is right.
The above only is an embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
