The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of sanding device for guideway vehicle, comprise two sandboxes 1, two stucco unit and stucco control modules 2, stucco unit comprises sander 3 and blast tube 4, sander 3 is installed on the bottom of sandbox 1, and be communicated with sandbox 1, between sander 3 and blast tube 4, be connected with stucco heating cabinet 5; Stucco control module 2 comprises gas path plate 20, stucco electromagnetic valve 21, dry electromagnetic valve 22 and reducing valve 23 are installed on gas path plate 20, wherein, stucco electromagnetic valve 21 is connected with the stucco ventilation inlet S being arranged on sander 3 by gas circuit pipe, for controlling the air-flow break-make of stucco air feed, dry electromagnetic valve 22 is connected with the dry ventilation inlet D being arranged on sander 3 by gas circuit pipe, for controlling the air-flow break-make of dry air feed, reducing valve 23 is connected with air-supply pipeline, for regulating the wind pressure that supplies that inputs to stucco unit.
Live contact cock 24 and test splice 25 are also installed on gas path plate 20, and wherein, live contact cock 24 is excised stucco when cutting off the air feed of whole sanding device and maintenance and fault, can, in isolation stucco, provide isolated condition signal; Test splice 25 detects the delivery pressure of stucco control module during for manual testing's reducing valve delivery pressure and maintenance and debugging.
Stucco heating cabinet 5 is arranged on the car body fixed mount of guideway vehicle, and stucco heating cabinet 5 is connected with the sand export R of sander 3 by sand pipe 6, and the sand export R of stucco heating cabinet 5 is connected with blast tube 4.
Stucco heating cabinet 5 inside are provided with heating rod, and when low temperature, heating rod starts, and heating sand pipe 6, to avoid sand pipe to freeze, guarantees the normal operation of sanding device, while having avoided low temperature because of the sand pipe obstruction causing of freezing, cannot stucco; In heating rod, be provided with temperature control apparatus, change power according to temperature traverse, make quantity of heat given up and dissipated heat balance, the temperature that guarantees stucco heating cabinet 5 can not exceed limit value, has so not only guaranteed that sand pipe 6 can not stop up but also prevent other parts on stucco heating cabinet 5 excess Temperature harm cars because of ice and snow.
The factors such as the vibratory impulse during due to vehicle operating, sand pipe 6 builds friction with the bogie truck of guideway vehicle, causes sand pipe 6 to wear and tear, and when serious, can cause sand pipe 6 to break, and stucco was lost efficacy.For this reason, the sand pipe 6 that connects stucco heating cabinet 5 and sander 3 sand export R adopts the rubber tube of metal sheath protection, can effectively reduce wearing and tearing, prevents that in vehicle operating process, sand pipe 6 breaks with car body friction.
As shown in Figure 5, above-mentioned sander 3 is provided with two gas circuit pipes that height is different, and two gas circuit pipes stretch in sandbox 1, and wherein, low gas circuit pipe 31 is sand pipe, and high gas circuit pipe 32 is freeing pipe.Under sandbox 1 internal pressure air effect, sand reserves sander by sand pipe, and unnecessary air is discharged sandbox 1 by freeing pipe.
The inside of sander 3 is provided with stucco quantity regulating device and dry heat rod, described stucco quantity regulating device comprise be arranged on stucco ventilation inlet S place choker dS, be arranged on the choker dD at dry ventilation inlet D place and be arranged on the choker dB at freeing pipe outlet air end place.By regulating the ratio of intake and air output, can among a small circle, regulate stucco amount, and can the pressure air of inflow be heated by dry heat rod, thereby to the sand heating in sandbox 1, the air-flow simultaneously flowing into is by loose the sand in sandbox 1, can prevent that the sand in sandbox 1 from hardening because of moist, affects stucco effect.
The top of sandbox 1 is provided with sand box cover composition 7, and sand box cover forms 7 and comprises sand box cover base 71 and be placed on the sand box cover 72 on sand box cover base 71, and sand box cover base 71 is arranged on sandbox 1; Between sand box cover 72 and sand box cover base 71, be connected by chain-falling 73, operating personal, in the time opening sand box cover 72, is vacated a hand without operating personal and is held sand box cover 72, can hold sand box cover 72 by chain-falling 73, convenient operation personnel work.
Come off when preventing that sand box cover 72 from vibrating, on above-mentioned sand box cover 72, be provided with draw ring stop pin 74, on sand box cover base 71, be provided with the knock hole matching with draw ring stop pin 74, while opening sand box cover 72, need first draw ring stop pin 74 to be pulled out, 90 ° of conter clockwise or clickwises, then rotate sand box cover 72 to opening position; While closing sand box cover 72, sand box cover 72 is rotated to close stance, by draw ring stop pin 74 repositions, draw ring stop pin 74 falls into the knock hole of sand box cover base 71 automatically, plays position-limiting action.
For prevent sander stop up time, the too high safety misadventure that causes of sandbox internal pressure, on above-mentioned sand box cover 72, be also provided with safety valve 75, in the time that sandbox 1 internal pressure reaches setting high pressure limit value, safety valve 75 on sand box cover 72 is opened, unnecessary pressure is discharged to sandbox 1, prevented the safety misadventure that hypertonia causes.
In order to produce better stucco effect, the end that shakes out of above-mentioned blast tube 4 is set to divided edge structure, when installation, adjusts this groove and can improve stucco effect towards rail level.
Principle of work:
Stucco air feed is entered by stucco ventilation inlet S, after the choker ds at stucco ventilation inlet S place regulates, enters sandbox by sintered plate from bottom.In sandbox, the pressurized air of supply is divided into two strands: the air-flow A of metering and the air-flow B of discharge.The air-flow A of metering flows in sandbox and sand is kicked up from sintered plate, and the sand of kicking up enters stucco cap, under the obstruction of stucco crown wall, enters and spreads sand pipe, then enters and removes sand outlet R.The sand that the air-flow B discharging flows through in sandbox makes them loose, finally discharges by freeing pipe.
Dry air feed enters by being dried ventilation inlet D mouth, and the choker dD at drying ventilation inlet D place enters the cavity of sintered plate bottom after regulating, and the heating rod H heating that is dried, and then enters in sandbox by sintered plate.Dry air feed is after choker dD regulates, and air quantity, much smaller than stucco wind supply quantity, can not transmit sand.Dry gas stream, for the sand of loose and dry sandbox, is finally discharged from the sand export R of sander by freeing pipe.
The transmission of sand is determined by the ratio of air-flow A and air-flow B; This is by the choker ds at stucco ventilation inlet S place and the internal diameter control of freeing pipe or can select to supplement at freeing pipe outlet air end place a choker dB in the time using the sand of decentralized.After converging, two strands of air-flows flow to stucco outlet R.
