Description
Technical field
The utility model relates to a kind of stucco system, for guideway vehicle.Belong to railcar technical field.
Background technology
Stucco system is vital parts on rail vehicle braking system, the various vehicles that guideway vehicle refers generally to travel in dedicated track, need under various harsies environment, move, particularly severe cold areas, wheel track easily freezes or skids, when locomotive is in emergency braking, when climbing, easily there is idle running or derailment occurring in vehicle, exists serious potential safety hazard.Therefore, the locomotive travelling in orbit is mostly equipped with stucco system, and domestic stucco system adopts gas circuit control more at present, that is, utilize aerodynamic force to produce negative-pressure siphon principle and realize stucco function.Although this system can realize stucco object, in its working process, exist some defects, as: higher to the parameter request such as compressed air pressure, flow, source of the gas degree of utilization is low, and stucco is inhomogeneous; Sandbox and blast nozzle all without heating arrangement or, while causing the operation of vehicle severe cold areas, lose stucco function because sand in stucco system freezes to stop up; In addition, existing stucco system is without sand level display apparatus, and operation bench can not be understood sandbox sand position in time, easily causes system non-productive work, affects locomotive operation safety.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of stucco system used for rail vehicle is provided, and this system can having air source, and accurate, the lower sand of stucco amount control is evenly unimpeded; System in sandbox inside and the design and installation of nozzle place have heating arrangement, make the system can weather-proof reliable operation; System has increased sand level display apparatus, sends and adds sand information in time to operation bench, guarantees locomotive reliability service.
The purpose of this utility model is achieved in that
A kind of stucco system used for rail vehicle, be characterized in: described system comprises sandbox, temperature booster and nozzle assembly, sandbox top is provided with Air compressor, bottom is provided with air sand blower, the ventilation inlet of Air compressor access air sand blower, the sand export access nozzle assembly of air sand blower, temperature booster is the bending of W shape and is arranged in sandbox, and is positioned at the top of air sand blower.
A kind of stucco system used for rail vehicle of the utility model, the upper portion side wall of its sandbox is provided with the first sand position instrument, and lower sides is provided with the second sand position instrument.
A kind of stucco system used for rail vehicle of the utility model, its nozzle assembly comprises nozzle and is arranged on the nozzle heater on nozzle.
Compared with prior art, the beneficial effects of the utility model are:
1, this system is installed on the temperature booster of the W shape of the top of air sand blower in sandbox, and more existing straight rod type temperature booster has increased the inner heating surface area of sandbox, effectively prevents sand in case to freeze; Increase the temperature booster of design and installation at nozzle place, can effectively prevent that nozzle oral area from freezing, thereby guarantee that the stucco of stucco system is smooth and easy, reliable operation.
2, a kind of stucco system used for rail vehicle of the utility model, its sand level display apparatus is made up of with the second sand position instrument that is installed on sandbox lower sidewall the first sand position instrument that is installed on respectively sandbox side wall upper part.When sand position is during lower than the first sand position instrument, operation bench sand position read-out is yellow warning, represents that in sandbox, sand amount is 1/3 of roughing sand amount, and prompt system adds sand; When sand position is during lower than the second sand position instrument, the warning that takes on a red color of operation bench sand position read-out, represents that in sandbox, sand is used up.By the setting of this sand position device, can avoid system non-productive work, guarantee the safety of locomotive running.
3, a kind of stucco system used for rail vehicle of the utility model, its air sand blower structure design uniqueness, adopts direct blast mode, makes evenly reliable, saving source of the gas of system stucco.Eliminated existing " negative-pressure siphon " stucco system higher to the parameter request such as compressed air pressure, flow, source of the gas degree of utilization is low, and the inhomogeneous defect of stucco.
