Abstract
The utility model discloses a bogie with a sanding device, wherein the device arranged under a structural frame can achieve timely and appropriate sanding, thereby achieving directional sanding in the specific weather and the road condition, so as to improve the adhesion force between a wheel and a rail. The bogie comprises two wheel sets, and the structural frame bears axle box bodies arranged at the two sides of an axle. The sanding device is installed under the structural frame, wherein the sanding device comprises a sand box, a sanding valve, a sanding hosepipe and a sand blasting device which are connected with one another in sequence; and the sand blasting device is lengthways arranged in front of the wheel sets.
Description
Technical field
The utility model relates to a kind of bogie truck that has sanding device that is applied to guideway vehicle, belongs to mechanical manufacturing field.
Background technology
Follow the fast development of domestic city track traffic, the speed per hour of present domestic main line railway has reached more than 380 kilometers, and is therefore more strict for the designing requirement of vehicle safety performance under the high-speed travel state.
The circuit that guideway vehicle travelled is comparatively complicated, as inclement weathers such as air humidity is big, sleet appear, the binding force of wheel surface and track descends, in case when implementing emergency braking, can't realize braking in than short range and directly have influence on the safety of vehicle operating.
Therefore, need take corresponding non-skid safety protection measure for the guideway vehicle of high-speed cruising.
In view of this, the special present patent application that proposes.
The utility model content
The bogie truck that has sanding device described in the utility model, its purpose be to solve problem that above-mentioned prior art exists and be provided with in frame underneath one realize in good time, the device of an amount of stucco, under particular weather and road conditions condition, realize directed stucco, to improve the binding force between the wheel track.
For realizing above-mentioned design goal, the described bogie truck that has sanding device mainly includes:
2 groups of wheels are right, and the framework carrying is installed on the both sides journal box body on the axletree.
The difference with the prior art part is, in frame underneath one sanding device is set,
Sanding device includes bonded assembly sandbox, sanding valve, stucco flexible pipe and sand blower successively, and sand blower is arranged at the right vertical the place ahead of wheel.
As above-mentioned basic scheme, sandbox is used for storing at ordinary times sand grains;
Sanding valve connects vehicle control system by electric pipeline, is selected to open the opportunity and control stucco amount of valve according to road conditions by control system;
The stucco flexible pipe is used for carrying sand grains from sandbox to sand blower;
Sand blower is used for sand grains and sprays to the track of wheel to vertical the place ahead, to increase the binding force of wheel surface and track.
For improve sand grains in sandbox in-to-in flowing power, be implemented in and discharge sand grains in any case fluently, the further innovative approach that can take is that sandbox has vertical downward diminishing funnel-shaped structure.
Convenience for guaranteeing to add sand grains under the prerequisite of not dismantling sandbox, improving operation can be provided with sand inlet at described sandbox top.
As mentioned above, the utility model has the advantage that the bogie truck of sanding device has and is:
1, can realize directed stucco according to particular weather and road conditions condition, under the prerequisite that improves binding force between the wheel track, guarantee the driving safety of high-speed track vehicle.
2, stucco mode is easy, is easy to On line inspection or adds sand grains, and workload is less.
Description of drawings
Now in conjunction with the following drawings the utility model is described further
Fig. 1 is the generalized section of described rail vehicle truck;
As shown in Figure 1, take turns to 1 framework 2, journal box body 3, sandbox 4, sanding valve 5, stucco flexible pipe 6, sand blower 7, sand inlet 8.
The specific embodiment
Embodiment 1, and as shown in Figure 1, the described bogie truck that has sanding device includes 2 groups of wheels to 1, and framework 2 carryings are installed on the both sides journal box body 3 on the axletree.
One sanding device is set below framework 2, and sanding device includes sandbox 4, sanding valve 5, stucco flexible pipe 6, sand blower 7.
Sandbox 4 has whole funnel-shaped structure, is provided with sand inlet 8 at its top.
Sand blower 7 is arranged at wheel to vertical the place ahead of 1.
As above-mentioned basic scheme, sandbox is used for storing at ordinary times sand grains;
Under inclement weather or road conditions condition, wheel descends to the binding force of 1 surface with track.The high-speed track vehicle is implemented glancing impact, vehicle control system sends and instructs to sanding valve 5, the valve of sanding valve 5 is opened, pressurized air is delivered to sand blower 7 with sand grains from sandbox 4, stucco flexible pipe 6, sand blower 7 sprays sand grains to the track of wheel to 1 vertical the place ahead again, helps shortening the car brakeing distance.
