Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in further detail.
As Figure 1-3, formula automatic sand dolly is driven at the disclosed station of this utility model, including electronic flat truck for carrying 11,
It is installed on the automatic sand system on this electronic flat truck for carrying 11,
This automatic sand system includes oil-free scroll air compressor machine 1, efficient filter cartridge dust remover 8, sand tank 3, upper sand rifle 6, inhales sand
Rifle 7, control unit 12 etc., the sand export bottom sand tank 3 is connected with the upper sand mouth of upper sand rifle 6 by pipeline, the valve 4 that shakes out, sand
Sand inlet bottom tank 3 is connected with the suction sand mouth inhaling sand rifle 7 by pipeline, suction sand valve 5, and the air inlet on sand tank 3 top passes through
Pipeline, the first three-way valve 2, oil-free scroll air compressor machine 1 are connected with the gas outlet of efficient filter cartridge dust remover 8, the row on sand tank 3 top
QI KOU is connected with the air inlet of efficient filter cartridge dust remover 8 by pipeline, the second three-way valve 9；3rd end of the second three-way valve 9
The mouth that gathers dust mouthful with the negative pressure of upper sand rifle 6 is connected；Efficiently the outlet port of filter cartridge dust remover 8 connects by the road relief valve 10.
Sand tank 3 is used for laying in locomotive sand, and during upper sand, locomotive sand loads locomotive sand box from sand tank 3 through upper sand rifle 6, inhales sand
Time, the locomotive sand inhaling sand rifle 7 suction entirely falls in sand tank 3.As it can be seen, sand tank 3 is hydrostatic column, it is provided with material
Position meter LS01 and pressure vacuum gauge 13, be respectively used to the sand amount in instruction sand tank 3 and force value；Air inlet pipeline, gas exhaust piping are even
It is connected to sand tank 3 top, the pipeline that shakes out, enters sandpipe road and be connected to bottom sand tank 3 so that the pipeline of whole automatic sand dolly is arranged
The most reasonable, succinct, compact, can avoid arranging due to pipeline and cause personnel and the damage of equipment during use, sand tank 3 in a jumble
Sand export be the tapering type horizontal discharging opening of large radius.
Oil-free scroll air compressor machine 1 is that the air conveying energy of automatic sand dolly provides equipment, the gas of whole upper sand dolly
Movable valve power source and automatic sand/suction sand power are all realized by oil-free scroll air compressor machine；This oil-free scroll pneumatics
Machine pressure at expulsion is only 0.8 bar (bar), respective line and sand tank all can not use pressure vessel so that carry safer, ring
Protect.
Efficiently filter cartridge dust remover 8 is the import filter plant of oil-free scroll air compressor machine 1, is used for avoiding dust etc. to enter pneumatics
Machine causes air compressor machine to damage.As it is shown on figure 3, efficiently the bottom of filter cartridge dust remover 8 uses Quick-open connecting structure 81, convenient timing
Clear up its internal dust, have in the middle part of casing and open inspection door 83 soon and be easy to quick-replaceable filter element of duster.
Control unit 12 includes main control chip, two control knobs, alarms etc., the valve 4 that shakes out, suction sand valve the 5, first three-way valve
2, the second three-way valve 9, relief valve 10, oil-free scroll air compressor machine 1 control end and alarm all with the control signal of main control chip
Outfan is connected, and two control knobs are connected with the control signal input of main control chip, (the first control of one of them control knob
Button processed) two gears of startup/stopping are set, another control knob (the second control knob) arranges sand loading/upper sand/three, suction sand shelves
Position.
Electronic flat truck for carrying 11 is carrier and the power resources of automatic sand dolly, and this electronic flat truck for carrying 11 uses
Formula is driven at station, uses 24V (DC) storage battery power supply, and this accumulator is powered for oil-free scroll air compressor machine 1 and control unit 12 simultaneously.
The connection at mouth of gathering dust of the negative pressure of upper sand rifle 6 has negative pressure dust-collecting pipe, and the airborne dust produced during collecting sand is kept away
Exempt to cause environmental pollution.
The operational approach of formula automatic sand dolly is driven at station of the present utility model:
During the operation of upper sand, being adjusted by the second control knob to " upper sand " gear, main control chip controls the second three-way valve 9 action,
The negative pressure making sand rifle 6 mouth that gathers dust connects with the air inlet of efficient filter cartridge dust remover 8, adjusts the first control knob to " startup "
Gear, oil-free scroll air compressor machine 1 starts work, pressurizes to sand tank 3, when in sand tank 3, pressure rises to a setting value, master control core
Sheet controls the valve 4 that shakes out and opens, and now, can carry out upper sand operation by the valve of the upper sand rifle 6 of operation, and produce during upper sand raises
Dirt is formed about negative pressure through the negative pressure dust-collecting pipe of upper sand rifle 6 at upper sand rifle 6 and collects the efficient filter cartridge dust remover 8 of feeding, through efficiently
After filter cartridge dust remover 8 filters, clean air enters oil-free scroll air compressor machine 1.
During upper sand, detecting through level-sensing device, in sand tank 3 during locomotive sand deficiency, alarm (e.g., display lamp) is reported to the police to carry
Workman's sand amount of waking up is not enough, and the first control knob is adjusted to " stopping " gear, adjusted by the second control knob to " sand loading " gear by workman,
Main control chip controls the second three-way valve 9 action so that sand tank 3 connects with the air inlet of efficient filter cartridge dust remover 8, and relief valve 10 is let out
In pressure makes sand tank 3, pressure constantly declines, when pressure vacuum gauge 13 shows no pressure, and sand tank 3 inlet cover of outwarding winding, people's frock
Sand, after sand tank is filled it up with, has tightened sand loading operation by inlet cover.
When inhaling sand operation, the second control knob is adjusted to " suction sand " gear, the first control knob is adjusted to " startup " gear,
Main control chip controls second three-way valve the 9, first three-way valve 2 action so that sand tank 3 connects with the air inlet of efficient filter cartridge dust remover 8
Logical, the first three-way valve 2 is connected with air, and oil-free scroll air compressor machine 1 starts, and in sand tank 3, pressure begins to decline, and sets when dropping to one
During definite value, main control chip controls to inhale sand valve 5 and opens, and now, can carry out inhaling sand by the valve of operation suction sand rifle 7 and operate,
The sand that in utilizing suction sand rifle 7 to inhale locomotive sand box or ground is unrestrained；Meanwhile, the dust laden air in sand tank 3 sucks efficient filter cylinder mistake
Filter 8, the air after filtration enters air through oil-free scroll air compressor machine the 1, first three-way valve 2.
The above is preferred embodiment of the present utility model and the know-why used thereof, for the technology of this area
For personnel, in the case of without departing substantially from spirit and scope of the present utility model, any based on technical solutions of the utility model base
Equivalent transformation on plinth, simple replacement etc. obviously change, within belonging to this utility model protection domain.
