Description
Technical field
The present invention relates to metro shield equipment equipment technical field.
Background technology
The earth that shield machine spiral is discharged takes on the slag car of rear supporting marshaling by band conveyor.Band conveyor is arranged in the afterbody of equipment bridge to No. 5 trailers, and the tightening device of belt feeder and actuating device are arranged on No. 5 trailers.
Being attached to the friction force that can reduce belt and roller after on belt due to earth thus slipping of the belt phenomenon can be produced, being attached on belt to reduce dregs, Belt Conveying owner drive part be provided with 3 road cleaning shoes with together with belt flushometer.Nowadays, in subway shield tunnel construction, more and more tunnel quality is focused on, and the civilized construction in work progress.But existing belt is scraped mud flushing system and completely belt can not be adhered to earth clean out in clay geology, especially when delivery speed is very fast, often occurs that belt seriously falls mud phenomenon, thus have a strong impact on the clean and tidy and construction in tunnel.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of belt dynamic gas pressure system, the residue clay be bonded on Suporting structure belt of belt conveyor can be cleaned out, and reduces shield machine belt slag-off phenomenon, ensures the clean and tidy and normal construction in tunnel.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of metro shield equipment belt conveyor automatic inflatable system, comprise chassis compressed air reservoir, pneumatic ball valve, pressure-modulation valve, compression indicator and pressure inflator, described inflator is mounted on belt bottom, described inflator is made up of connection pipe and gas filled head, one end of described connection pipe is connected with described chassis compressed air reservoir, the other end is connected with described gas filled head, and described pneumatic ball valve, pressure-modulation valve and compression indicator are separately positioned on described connection pipe.
Further, also comprise PLC control module, described PLC control module is by the break-make of pneumatic ball valve described in the velocity response module controls that is arranged on belt slave wheel.
Further, described gas filled head is arranged on 15cm position, belt bottom, and described gas filled head is provided with the vertical qi of chong channel ascending adversely mouth of 4 axis, and inside, qi of chong channel ascending adversely mouth upper end is provided with the air extractor duct of three different angles.
Further, described pressure inflator intake pressure is 2 to 3bar.
Further, described qi of chong channel ascending adversely mouth is equipped with noise silencer, and described noise silencer adopts Ya De visitor type PSU2 to divide plastics silencer.
The beneficial effect adopting technique scheme to produce is: the present invention is by installing pressure inflator additional in 15cm position, belt bottom, and residue dregs rinses by actv..The noise emission of qi of chong channel ascending adversely system can be effectively reduced by the noise silencer installed additional at gas filled head.Achieved the automatic control of qi of chong channel ascending adversely system by PLC control module, the present invention is enough in cleaning out being bonded at the residue clay on shield machine belt, reduces shield machine belt slag-off phenomenon, ensures that tunnel is clean and tidy.Through overtesting on shield machine (No. 137), the contrast effect before and after application obviously improves; Relative to cleaning shoe compared with flushing system, qi of chong channel ascending adversely system overcomes the wearing and tearing of cleaning shoe Long-Time Service, and to cause scraping mud unclean, avoiding washes by water when special formation normally tunnels as flushing system too much can cause a large amount of muddy water to overflow slag bucket, increases the phenomenons such as secondary construction workload.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, the present invention is a kind of metro shield equipment belt conveyor automatic inflatable system, comprise chassis compressed air reservoir 1, pneumatic ball valve 2, pressure-modulation valve 3, compression indicator 4 and pressure inflator, described inflator is mounted on belt bottom, described inflator is made up of connection pipe 5 and gas filled head 6, one end of described connection pipe 5 is connected with described chassis compressed air reservoir 1, the other end is connected with described gas filled head 6, and described pneumatic ball valve 2, pressure-modulation valve 3 and compression indicator 4 are separately positioned on described connection pipe 5; Described gas filled head 6 is arranged on 15cm position, belt bottom, described gas filled head 6 is provided with the vertical qi of chong channel ascending adversely mouth 7 of 4 axis, and inside, qi of chong channel ascending adversely mouth 7 upper end is provided with the air extractor duct of three different angles, air extractor duct in the middle of it is parallel with qi of chong channel ascending adversely mouth, two other air extractor duct is 25 degree with middle air extractor duct, thus add the qi of chong channel ascending adversely area of qi of chong channel ascending adversely system, the contact time of belt conveyor and qi of chong channel ascending adversely system is increased, improves and blow down earth effect; Described pressure inflator intake pressure is 2 to 3bar; Described qi of chong channel ascending adversely mouth 7 is equipped with noise silencer, and described noise silencer adopts Ya De visitor type PSU2 to divide plastics silencer, and it act as the Aerodynamic Noise of A reducing pneumatic element or device exhaust, can be directly installed on the exhausr port of element or device.
As shown in Figures 2 and 3, the present invention also comprises PLC control module, and described PLC control module is by the break-make of pneumatic ball valve 2 described in the velocity response module controls that is arranged on belt slave wheel.The present invention arranges a velocity response module at belt slave wheel place, feed back to PLC control module, set a velocity amplitude in advance PLC control module, after PLC control module detects that actual speed is greater than setting value, output digit signals gives outside intermediate relay 1k2, controls the break-make of pneumatic ball valve kqv 01 with 1k2.The object automatically controlling belt and rinse is reached with this.
Embodiment:
The present invention is arranged on belt puncher water system near 80cm place, driving wheel direction, qi of chong channel ascending adversely mouth distance belt bottom 15cm.After tested, belt can be remained dregs and rinses by most actv. by design attitude herein.Design specification, this qi of chong channel ascending adversely system main qi of chong channel ascending adversely pipeline be 1 cun high pressure resistant, corrosion prevention, explosion-proof steel pipe used, maximum withstand voltage 16bar, connection pipe is the high pressure resistant flexible pipe of 1.5 meters, maximum withstand voltage 16bar.Control system adopts belt speed detector, when detecting that belt runs, automatically carries out qi of chong channel ascending adversely operation.For reducing the noise emission of this qi of chong channel ascending adversely system additional, noise silencer is installed to each air nozzle.Final combination test, pressure-modulation valve is set in about 2.5bar, belt can be remained dregs and rinses well and be reduced to by noise minimum.
This belt system is by after field measurement, and belt attachment earth has significant change.Particularly in clay stratum, belt, after qi of chong channel ascending adversely, adds flushing system than original cleaning shoe, and successful improves.This system greatly reduces shield machine belt slag-off phenomenon, reduces the work capacity of tunnel civilized construction.
