The stabilization of cleaning vehicle is kept to drive into and be driven out to.
As shown in figure 4, further, the spray water pipe device 6 includes spray piping 22, outlet conduit 23, water outlet
24；The spray piping 22 is L-shaped；The water outlet 24 is arranged on the outlet conduit 23；The water outlet 24 is described
It is arranged in array on outlet conduit 23.It by the way that multiple water outlets 24 are arranged, can be discharged simultaneously, and greater angle cover
Lid guarantees the stability of ash disposal dedusting.
Further, the water outlet 24 is on the outlet conduit 23 in the arrangement that curves inwardly；On the water outlet 24
Equipped with nozzle 28；The nozzle 28 is in infundibulate.Funneling is set by nozzle 28, guarantees to be sprayed onto during water spray
In corresponding range, guarantee the impact force of water spray.
Further, the water tank 4 is equipped with relief valve 25 and one-way cock 26.Relief valve 25 may insure oversize vehicle
By when, the safety of water tank 4 and pipeline.One-way cock 26 may insure to flow back after the water of water tank 4 can be precipitated and carry out
It recycles.
In actual operation, one-way cock 26 is set at the top of water tank 4, when trestle 1 is promoted, the water of 4 surrounding of water tank reflux
Enter from 26 hole of one-way cock.When trestle 1 declines, one-way cock 26 is in close state, and guarantees the water of 4 the inside of water tank from out
The mouth of a river 24 sprays.Pressure valve, which is arranged, in water tank 4 prevents the excessively high destruction equipment of hydraulic pressure when there is oversize vehicle to pass through.When pressure is greater than
When 10MPa, relief valve 25 automatically opens pressure release, and when pressure is lower than 10MPa inside water tank, relief valve 25 is automatically closed.
As shown in figure 5, further, the water tank 4 is equipped with support column 27；24 upper end of support column and the trestle
1 connection.By supporting 27 effect come the case where applying certain pressure to water tank 4, trestle 1 is avoided to rotate down suddenly,
Play the role of a buffering.
In actual operation, when not having vehicle pass-through, clump weight 12 passes through pulley blocks 11 using the gravity of itself
Adjustment effect by 1 pull-up of type trestle, switch railing 3 and be in downward closed state under the effect of gravity.When there is vehicle driving to arrive
When 1 one end of trestle, under the action of vehicle weight, the weight of clump weight 12 is not enough to balance trestle 1 at this time, 1 middle part of trestle
It will move downward.Since the middle part of 1 lower end of trestle is equipped with support column 27, support column 27, can be with by the effect of supporting point
To the buffer function of following water tank 4, will be unlikely to trestle 1 occur to rotate down phenomenon suddenly.By supporting point to water tank 4
The water of compressing, 4 the inside of water tank will be by spray water pipe device 6 to 1 intermediate injection water flow of trestle, to reach the live dust of reduction
And rinse the purpose of vehicle.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest scope of cause.
