Abstract
Disclosed is a sand spreading method of a locomotive sand spreader. The sand spreading method is characterized in that sand is stored in a sand storage tank and flows into a sand blowing cavity through an upper cover of the sand spreader; and a sand blowing nozzle is arranged at the top of the sand blowing cavity, and the sand blowing nozzle ejects compressed air to blow the sand entering the sand blowing cavity and lift the sand along a separation board between the sand blowing cavity and a sand spreading cavity. A sand spreading nozzle is arranged at the top of the sand spreading cavity, and the sand spreading nozzle blows the compressed air to the sand spreading cavity so that on one hand, negative pressure is formed in the sand spreading cavity, and the sand lifted along the separation board between the sand blowing cavity and the sand spreading cavity is absorbed into the sand spreading cavity; and on the other hand, the sand entering the sand spreading cavity is blown into a sand ejecting cavity in a valve body through pressure and then spread out through a sand spreading pipe.
Description
Technical field
The present invention relates to a kind of operational method and parts of locomotive, especially refer to for increasing the adhesion between wheel tread and rail, improve the traction of locomotive and the method that sands and the device of deceleration and stopping performance, international Patent classificating number is B61F05/02, is mainly used in the system that sands of locomotive.
Background technology
Because travelling by steel wheel in the up realization of coming up of rail of guideway vehicle, steel wheel and rail all are very smooth surfaces, think the adhesion that increases between wheel tread and rail, improve traction and the deceleration and stopping performance of locomotive, prevent that running down is slided when drawing hour wheel to idle running and braking, all be provided with sanding device in various internal combustion and the electric locomotive, generally before and after each bogie truck, be provided with sandbox and sander.Locomotive sand spraying device is except the manual control of accepting the driver, also with brake, idling slide protective system (adhesion control system) and disconnected hook protection mating reaction.Automatic block signal is that roller is controlled the short circuit track circuit.When light locomotive running, if carry out emergency braking, sanding device is automatic stucco, the parking hour wheel to and rail between spread the nonconducting sand of one deck, make wheel to can not fine short circuit track circuit, make train signal show mal, easily cause rear-end collision.
The present locomotive emergency braking control setup that sands, mostly adopt the device of automatically control to sand, detect in real time the state of locomotive operation with car, when train because the electric control braking controller is put urgent position, service register sends the emergency braking instruction, draw the train pipe vent valve, when disconnected hook or train pipe fracture or breakage, the robot brain car is in speed normal stucco during greater than 10km/h, forbid stucco during less than 10km/h in speed, the parking hour wheel to and rail between without sand, make wheel to short circuit track circuit well, signal normally shows, thereby guarantee the safe operation of train, prevent the generation of train operation accident.
In the system of sanding, sand and finally by the device control that sands sand is spread out, the structure of present sanding valve mostly as shown in Figure 1, can find out by accompanying drawing, the sand of the existing device that sands is to be contained in the container, utilize blast that sand is sprayed by the mouth that sands, but the outlet of the present device that sands, in order to prevent that sand from flowing out voluntarily, just flow out through a bend, therefore often this structure has greatly affected the mobile fluency of sand drift, situation about stopping up occurs, and necessary this is improved.
Find to have much patents about liquid cooling heat radiator by patent retrieval, wherein related to the present invention mainly contain following:
1, the patent No. is CN200820023587.8, and name is called the Chinese utility model patent of " a kind of sand spraying apparatus ", and this patent discloses a kind of sand spraying apparatus, belongs to the electric locomotive accessory device.Its technical scheme is: it comprises sandbox, and corresponding sand outlet place is provided with screw charging ram in the sandbox, and screw charging ram is connected with sandbox transmission device outward, and transmission device is connected with actuating unit.
2, the patent No. is CN200680005343.0, name is called the Chinese invention patent of " method and system that restriction applies the sand on the rail ", this patent discloses a kind of method that limits the use of railway locomotive Shi Sha system sand, described railway locomotive Shi Sha system with sand applied to the rail with the wheel of strengthening railway locomotive in the binding force that has on the track of a pair of rail, described Shi Sha system comprises a plurality of sand applicators for each rail, be used for to described rail-guided sand drift, and described locomotive has two bogie trucks that the support are housed and promote the wheel of this locomotive along track, described method comprises: automatically control is applied the sand drift of described rail by described locomotive Shi Sha system, so that applying of sand is restricted to such situation: wherein, applying sand will be effectively increase the binding force of at least one wheel on described rail in the described railway locomotive wheel with predetermined recruitment to described rail.
Above-mentioned these patents although all relate to sand spraying apparatus, are not mentioned inner flow passage structure, but by carefully analyzing, can find that its inner structure is still simple flow passage structure, therefore still can not solve the problem that the existing device that sands stops up, need to do to this further improvement.
Summary of the invention
The object of the invention is to for the existing device inner structure that sands too complicatedly, the deficiency stopped up often occurs, proposes a kind of locomotive with optimization inner flow passage structure sand method and the device that sands; Sand method and the device that sands of this kind locomotive can greatly reduce the phenomenon that sand stops up, and can improve the fluency that sands.
