Group 13 is connect after inverter 12 with electrical equipment.
When this mobile tunnel dust-extraction unit, which is in, walks non-dust removal state, the hydraulic branch of front chassis 17 and rear chassis 14
Leg is upper to be received, because front chassis 17 and rear chassis 14 pass through rod head 15 and connect, to realize synchronizing moving and walking.Principal arm 4
It collapses and rotates with the telescopic arm of auxiliary 2, the dust removal port of flexible duct 1 is turned into tailstock direction, to provide for driver
The good visual field.While principal arm 4 and auxiliary 2 collapse, flexible duct 1 under the traction of suspension hook with telescopic arm collapse process into
Row sliding, is collapsed simultaneously.The hydraulic jacking device of 8 lower section of dedusting fog gun collapses, and reduces the height of dedusting fog gun 8, is sprayed
Mouth is in a horizontal state.
As shown in Figure 1, when mobile tunnel dust-extraction unit is in dust removal state, front chassis 17 and rear chassis 14 it is hydraulic
Supporting leg elongation and ground face contact.Under the operation of driver, principal arm 4 is rotated around principal arm revolving platform 5, and is directing forwardly principal arm 4.
Then, one end of flexible duct 1 and air hose steering knuckle 18 are attached with anchor ear, adjustment 1 top suspension hook of flexible duct and
The position of hanging ring.As the stretching of principal arm 4 is unfolded, flexible duct 1 also draws high expansion simultaneously under the drive of suspension hook.Spread length
Distance by this dust-extraction unit apart from working region determines.When the expansion of principal arm 4 still can not arrive at dedusting operating area,
Under driving force effect, auxiliary 2 can be rotated around auxiliary revolving platform 3, and the suspension hook of 1 front end of flexible duct is adjusted to auxiliary 2
On, with the stretching of auxiliary 2, flexible duct 1 is further spread out, arrives at dedusting operating area.
In addition, in order to avoid principal arm 4 and cockpit 6 collide, while reducing flexible duct 1 in operation process and existing
The torsion and deformation generated in steering procedure causes windage to become larger and damages with air hose, steering of the present apparatus to principal arm 4 and auxiliary 2
Angle is limited, and rotational angle is -45 ° ~ 45 ° (extended line is 0 ° of line of demarcation immediately ahead of driving direction).But in auxiliary 2
After expansion, auxiliary 2 also has -45 ~ 45 ° of rotational angle range, therefore the maximum operation region of this dust-extraction unit will cover just
The job space range of -90 ° of front ~ 90 °.
After the adjustment of flexible duct 1, principal arm 4 and auxiliary 2, the work of the hydraulic jacking device thereunder of dedusting fog gun 8
Certain height is given rise to lower, and by flexible and hydraulic motor the drive of hydraulic cylinder, realizes the pitching of dedusting fog gun 8
And rotation.
After the mouth that gathers dust of flexible duct 1 reaches dedusting work surface, firstly, being carried out by dedusting fog gun 8 to operating area
It is spraying, the large dust particle in space is subjected to water mist sedimentation.Then, pneumatic by axis stream dedusting fan 9, in flexible duct 1
Interior formation negative pressure gathers dust flexible duct 1 in the dust sucking air hose of mouth.As shown in figure 3, at a mouthful end of gathering dust for flexible duct 1
Portion is provided with dust-filtering net, is filtered for the first time to dust, it is online that large particle is deposited in dust-filtering.Fine dusts are then led to
Mesh is crossed to enter in flexible duct 1.Then, the air containing dust enters in deduster 7, under the action of negative pressure, dust quilt
Dust filter bag in deduster 7 is adsorbed in surface, and clean gas then passes through the case that filter bag gap enters water storage water-bath integrated box 16
In vivo.The dust being attached on dedusting filtering bag forms rapping on cage skeleton, falls under the action of pulse backblowing compressed gas
It drops down onto and is collected in the hopper of 7 lower section of deduster.
As shown in figure 4, the gas for entering water storage water-bath integrated box 16 is needed in air inlet across spraying nozzle 162
The veil formed of spraying water changes fortune then with certain velocity shock water surface under the comprehensive function of the water surface and diaphragm 163
Dynamic direction, flows out from air outlet.Grit then due to the effect of inertia, rushes at the water surface, adheres to water, achievees the purpose that dedusting.Water
Dissolved with certain density gas purifying agent in water in bath cabinet, while dedusting, the primary evolution of pernicious gas is realized.
The gas come out from water bath enters in the second steel air hose 20 of 9 front end of axis stream dedusting fan, the second steel
Deflector is arranged in 20 interior forward end of air hose, hits deflector containing water flow after water-bath, liquid pearl is attached on deflector, real
Existing gas-water separation.By the micro-porous adsorption device of 20 rear end of the second steel air hose, secondary purifying is carried out to the pernicious gas in gas
Change, is discharged eventually by axis stream dedusting fan 9, dust collecting sleeve 10.
In the present apparatus course of work, all electric energy are provided by the battery group 13 of 14 top of rear chassis, battery
Charge and discharge then have and charge with the charging pile matched.It is converted by 12 pairs of electricity systems of inverter, matches the electricity system of electrical equipment
Demand；Power storage management system 10 can prevent overcharge, overdischarge, realize temperature control and balance, energy resource system information
The functions such as prompt, battery status test and display.
