Abstract
The utility model relates to a trail locomotive sanding control system, in particular to a locomotive sanding device for safe operation of a locomotive, which comprises a sand box, wherein a sand box outlet is arranged at the bottom of the sand box. The locomotive sanding device is characterized by further comprising a sensor and a sanding controller arranged on the lower side of the sand box and used for controlling sanding amount. A sand inlet at the top end of the sanding controller is connected with the sand box outlet. The sanding controller comprises a logic control unit and a gear arranged below the sand inlet and controlled by a motor. The logic control unit comprises a speed signal processing module and a central processing module, the sensor is communicated with the speed signal processing module, the rotating speed of the motor is controlled by the central processing module, and a sand outlet is arranged on the lower side of the gear in the sanding controller. The sanding amount is controlled by controlling the rotating speed of the gear and the rotating speed of the motor in the sanding controller. Therefore, the locomotive sanding device is safe, reliable, ingenious in structure, good in anti-slipping effect and capable of reducing braking distance and abrasion of wheels by utilizing rail surface adhesion to the largest extend.
Description
Technical field
The utility model relates to rail locomotive stucco control system, refers to a kind of sanding device that is used for locomotive safety running especially.
Background technology
Sliding of rail locomotive wheel is inevitably, can bring very big harm and slide to rail locomotive, and the lighter understands flat wheel tread and rail, and weight person can increase the stopping distance of locomotive, causes serious accident.
There are two kinds of modes in the stucco system that uses on the locomotive at present: a kind of is initiatively to apply stucco through the operator, mainly is through pushing stucco button or foot-operated stucco pedal, thus control stucco electropneumatic valve dead electricity realizes whether stucco of locomotive; The speed of the logic control element of another kind of locomotive through locomotive and the emergency state control the stucco electropneumatic valve the whether stucco of dead electricity realization locomotive; And mostly sanding device is gravity type boat davit and differential at present.In the middle of practical application, not enough below current sanding device exists: 1. as under the service braking state, can't to carry out stucco according to the sliding state of speed and wheel; 2. when locomotive is implemented automatic stucco, only can control sanding device and carry out the discountinuity stucco, and can not be according to the size of actual conditions automatic guidance stucco amount; 3. present sanding device is owing to the main self gravitation of sand grains that leans on forms the stucco effect, and therefore the setting height(from bottom) to sandbox has specific requirement, is unfavorable for the entire arrangement of equipment.
Summary of the invention
The utility model technical matters to be solved is: the deficiency to above-mentioned prior art, a kind of locomotive sanding device is provided, and this device can require to regulate the size of stucco amount according to control, does not receive the influence of sandbox installation site.
The technical scheme of the utility model is: a kind of locomotive sanding device; Comprise sandbox, the sandbox bottom is provided with the sandbox outlet, it is characterized in that; Also comprise sensor and the stucco controller that is located at the control stucco amount of sandbox downside; The sand inlet on stucco controller top links to each other with the sandbox outlet, and said stucco controller comprises logic control element and be located at the gear of sand inlet below by electric machine control that said stucco logic control element comprises speed signal processing module and central processing module; Said sensor is communicated with the speed signal processing module and by central processing module control rotating speed of motor, stucco controller inner gear downside is provided with sand export.
Stucco controller one side is provided with admission port, is provided with shrinkage cavity between this admission port and the stucco controller sand export.
Stucco controller sand export bottom is connected with the stucco pipeline.
Logic control element control motor rotates, the motor driven gear rotation, and the rotation of gear can drive the inside of sand grains to the stucco controller in sandbox exit; Stucco controller sand export link to each other with the stucco pipeline and the rail level through stucco pipeline to appointment on.
The utility model has the advantages that: this device is controlled the size of stucco amount through the rotating speed of motor and gear in the control stucco controller; Safe and reliable, structure is ingenious, good antiskid effect; Can utilize the rail level adhesion to greatest extent, reduce stopping distance, reduce the wearing and tearing of wheel.
Description of drawings
Fig. 1 is the constructional drawing of the said sanding device of the utility model.
The specific embodiment
As shown in Figure 1; A kind of locomotive sanding device comprises sandbox 1, and sandbox 1 bottom is provided with sandbox outlet 2; Also comprise sensor and the stucco controller that is located at the control stucco amount of sandbox 1 downside; The sand inlet 4 on stucco controller top links to each other with sandbox outlet 2, and the stucco controller comprises logic control element 3 and be located at the gear 9 of sand inlet 4 belows by electric machine control that stucco logic control element 3 comprises speed signal processing module and central processing module; Said sensor is communicated with the speed signal processing module and by central processing module control rotating speed of motor, stucco controller inner gear 9 downsides are provided with sand export 7.
Stucco controller one side is provided with admission port 6, is provided with shrinkage cavity 5 between this admission port 6 and the stucco controller sand export 7.
Stucco controller sand export 7 bottoms are connected with stucco pipeline 8.
