Abstract
The utility model relates to a sand spreader tuyere for a locomotive. The sand spreader tuyere comprises a tuyere body and a tuyere mouth, wherein an air flue is arranged in each of the tuyere body and the center of the tuyere mouth. The sand spreader tuyere is characterized in that the head part of the tuyere mouth is a conical surface, so that the tuyere mouth protrudes outwards to form a mouth; a locking nut is arranged at the back part of the tuyere body and used for fixing the tuyere; the head part of each air flue is provided with a conical reamed hole which is convenient for being connected with the air flues on the sand spreader; and the cone angle of the conical surface of the head part of the tuyere mouth is 120-160 degrees. As the structure of the sand spreader tuyere is changed, the original horn mouth is changed into the conical surface, and the negative pressure effect of the tuyere can be reduced, so that the tuyere is not easily plugged by sand; and in addition, the sand spreader tuyere is simple in structure, good in effect and worthy of being popularized.
Description
Technical field
The utility model relates to a kind of parts of locomotive, especially refers to for increasing the adhesion between wheel tread and rail, improves the traction of locomotive and the device tuyere that sands of deceleration and stopping performance, and international Patent classificating number is B61F05/02, is mainly used in the system that sands of locomotive.
Background technology
Due to travelling by steel wheel in the up realization of coming up of rail of guideway vehicle, steel wheel and rail are all 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 electric locomotive, generally be provided with sandbox and sander before and after each bogie truck.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 controlling 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 finally to control by the device 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 a container, utilize blast that sand is sprayed by the mouth that sands, but the tuyere of the present device that sands is the bell mouth shape that adopts, why like this design be wish wind out more even, find that in actual applications this structure easily causes the obstruction of the grains of sand, make sand be difficult to kick up, therefore the situation of obstruction often appears, necessary this is improved.
Find to have much patents about liquid cooling heat radiator by patent retrieval, wherein relevant to the utility model 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 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 utility model patent of " method and system that restriction applies the sand on 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 the sand drift that is applied described rail by described locomotive Shi Sha system, so that applying of sand is restricted to such situation: wherein, applying sand will be effectively with the binding force of at least one wheel on described rail in the predetermined described railway locomotive wheel of recruitment increase to described rail.
Above-mentioned these patents although all relate to sand spraying apparatus, are not mentioned the deficiency of air nozzle structure, therefore still can not solve the problem that the existing device tuyere that sands stops up, and need to do to this further improvement.
The utility model content
The purpose of this utility model is for the existing device air nozzle structure that sands unreasonable, the deficiency stopped up often occurs, proposes a kind of locomotive of optimizing structure device tuyere that sands that has; This kind locomotive device tuyere that sands can greatly reduce the phenomenon of the tuyere that sand stops up, and improves the effect of kicking up of sand.
The utility model is achieved through the following technical solutions: a kind of locomotive is with the device tuyere that sands, comprise a tuyere body and wind mouth mouth, be provided with the air channel at the center of tuyere body and wind mouth mouth, its characteristics are, the head of wind mouth mouth is conical suface, makes wind mouth mouth for outwards giving prominence to the mouth shape.
Further, be provided with jam nut in the aft section of tuyere body, be used for fixedly tuyere.
Further, described air channel head has conical countersink, is convenient to be connected with air channel on the device that sands.
Further, the cone angle of described wind mouth mouth head conical suface is the 120-160 degree.
The utility model has the advantage of:
The utility model changes original exit skirt into conical suface by the sand structure of device tuyere of change, can reduce the suction function of tuyere, makes salad be not easy to stop up tuyere at the tuyere place, and simple in structure effective, is worthy to be popularized.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
In figure: 1, tuyere body; 2, wind mouth mouth; 3, the head of wind mouth mouth; 4, air channel; 5, jam nut; 6, conical countersink.
The specific embodiment
