It causes huge harm, and visibility is reduced, cause construction personnel unsighted, reduce construction efficiency.It uses at this stage
In the blower of tunnel dedusting, its fan induced draught air duct is unable to telescopic adjustment, and in the case, construction personnel must be by digging machine etc.
Other equipment complete the movement of blower and the adjustment of air inlet, the use of fan bring very big inconvenience.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides a kind of tunnel dust removal machine Telescopic air duct, operators
Member can according to the adjustable air draught air duct length of condition of construction, to guarantee that dust removal machine is dusted operation in place,
Efficiently remove the dust generated in work progress.
To achieve the goals above, the technical solution adopted by the present invention is that: a kind of tunnel dust removal machine Telescopic air duct, including
Air draught air duct and telescopic device；The telescopic device includes multi-stage telescopic arms, and the flexible front end of first segment is equipped with air duct hitch frame,
Air duct hitch frame is connect with air draught air duct end top；Multi-stage telescopic arms are flexible to elongate or shorten air draught air duct.
The present invention is further, and the air draught air duct is bellows.
The present invention is further, and every section telescopic arm of the telescopic device has a connection frame, connection frame and air draught wind
Cylinder connection.
The present invention is further, and the telescopic device further includes pulley and wirerope；Pulley is connected with telescopic arm, wirerope
One end is fixed on air duct hitch frame, and the other end is connected with telescopic arm rear end, centre pass through pulley, air draught air duct telescopic section with
Wirerope is connected.
The present invention is further, and the rear end of the air draught air duct is connected with dedusting fan, the telescopic device bottom installation
On dedusting machine platform.
Tunnel dust removal machine Telescopic air duct air draught air duct of the present invention can be with telescopic adjustment length, in the construction process, when need
When adjusting air duct position, construction personnel can control telescopic device and stretch, and drives the flexible of air draught air duct, is guaranteed with this
Air duct has the length for being suitble to dedusting operation.With this, operator is no longer needing other equipment auxiliary to can be completed to dedusting
The adjusting of the air draught air duct of equipment improves the flexibility of equipment, guarantees efficiency of dust collection, reduces dust concentration, it is ensured that construction effect
Rate.
Detailed description of the invention

Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
As shown in Figure 1, a kind of tunnel dust removal machine Telescopic air duct of the present invention, including air draught air duct 1 and telescopic device 2；Institute
Stating telescopic device 2 includes multi-stage telescopic arms 2-4, and first segment stretches front end equipped with air duct hitch frame 2-1, air duct hitch frame 2-1
It is connect with 1 end top of air draught air duct；Multi-stage telescopic arms 2-4 is flexible to elongate or shorten air draught air duct 1.
On the basis of the said structure, the present invention provides a kind of embodiment of air draught air duct 1, is bellows, also referred to as wave
Line compensator can guarantee effective dilatation, naturally it is also possible to using other suitably flexible form of tubes.
Since air draught air duct 1 is longer, in order to avoid air draught air duct 1 itself drops in elongation, in addition to telescopic device 2 and inhale
1 end of wind air duct is outer by air duct hitch frame 2-1 connection, here the connection at 1 middle part and telescopic device 2 of increase air draught air duct, and one
Kind connection type is to have a connection frame in every section telescopic arm, connection frame is connect with air draught air duct 1.
Another connection type is that pulley 2-2 and wirerope 2-3 is arranged on telescopic device 2；Pulley 2-2 and telescopic arm
The lower part 2-4 is connected, and the one end wirerope 2-3 is fixed on air duct hitch frame 2-1, and the other end is connected with the end telescopic arm 2-4, intermediate
Across pulley 2-2,1 telescopic section of air draught air duct is connected with wirerope 9.
As shown in Fig. 2, the present invention provides a kind of embodiment of integral installation, by the rear end of air draught air duct 1 and dedusting fan 6
It is connected, 2 bottom of telescopic device is mounted on above dedusting machine platform 4.
It is incorporated on telescopic device 2 that pulley 2-2 and wirerope 2-3 is arranged is embodiment, as shown in figures 1 and 3, air draught
The contraction process of air duct are as follows: when telescopic arm 10 extends, drive air duct connection frame 7 and air draught air duct 1 is driven to extend, while steel wire
Rope is 9 locking, and when guaranteeing that telescopic arm 10 extends, wirerope 9 is not damaged, and when air draught air duct 1 is elongated to appropriate length, stops stretching
Contracting arm 10 extends, while tightening wirerope 9, guarantees that air draught air duct 1 will not be sagging；When telescopic arm 10 is shunk, air duct is driven to connect
It connects frame 7 and air draught air duct 1 is driven to shrink, while wirerope 9 is tightened, when air draught air duct 1 is retracted to appropriate length, stopping is flexible
Arm 10 is shunk, while adjusting wirerope 9, guarantees that air draught air duct 1 will not be sagging.
In conclusion dust removal machine workflow in tunnel of the present invention is as follows:
Firstly, starting tunnel dust removal machine dynamical system 3, adjusts telescopic device 2, guarantee that air draught air duct 1 is retracted to most short shape
State, then, control complete machine are walked, and when complete machine is walked to designated position, after being come to a complete stop, adjustment 1 length of air draught air duct is opened
Dynamic dedusting fan 6, dedusting fan 6 can by the air largely containing dust by the front end inspiration of air draught air duct, then again it is internal into
Then row depositing dust, dust removal process clean air are discharged from 6 rear end of dedusting fan.After completing dedusting, air draught air duct is shunk
1, guarantee that entire work progress is unaffected.
Certainly, above-described embodiment is only preferred embodiment of the invention, is specifically not limited thereto, on this basis can basis
Actual needs is made having and targetedly be adjusted, to obtain different embodiments.Since mode in the cards is more, this
In just no longer illustrate one by one.
