There is one group of installation screw.
The advantages of invention：
When the roadway construction of high inclination-angle in mine, the present invention can make full use of negative pressure air duct Gravitative Loads so that
The surplus of air duct can be gathered to one end, install storage metal frame in air duct accumulation section, can prevent air duct from skew back occurs, and can is protected
Sufficient ventilation section is demonstrate,proved, so as to play the continuation ventilating dust-removing effect for ensuring negative pressure air duct.In addition, the present invention also has knot
Structure is simple, easy to use, is easy to be mounted directly on existing equipment, can avoid negative pressure air duct skew back, and incite somebody to action this
After device is installed in place, the height of air duct storage metal frame according to the height of drive, can be arbitrarily adjusted.
Brief description of the drawings：
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the front view of air duct storage metal frame in Fig. 1；
Fig. 3 is working state schematic representation of the present invention；
Fig. 4 is another working state schematic representation of the present invention.
Embodiment：
As shown in figure 1, a kind of stretching recover of negative pressure air duct, it, which is included in mine wall, is hung with steel wire rope 1.If
A negative pressure air duct 2 is put, one group of link 1a with the corresponding matching of steel wire rope 1 is provided with the outer wall of negative pressure air duct 2, to bear
Pressure air duct 2 is suspended on steel wire rope 1, and negative pressure air duct 2 can be made to be moved forward and backward along steel wire rope 1.
A piece vertical montant 6 is set, a cord hole 3a with the corresponding matching of steel wire rope 1 is provided with the top of montant 6,
The bottom of montant 6 is provided with a screw rod 6a being coaxial therewith, then sets a thickening hollow tube 3, is thickening the upper end of hollow tube 3
Provided with gear-box 6b.
Described screw rod 6a lower end is stretched into the tube wall for thickening hollow tube 3 again after passing through gear-box 6b.In described tooth
Lifting rocking bar 6c is additionally provided with roller box 6b, realizes screw rod 6a up and down motion by rotating lifting rocking bar 6c, and then realize perpendicular
The lifting of bar 6, and the axis of described montant 6 is conllinear with the axis for thickening hollow tube 3.
As shown in Figure 1, 2, an air duct formed by bonding jumper braiding is set to store metal frame 4, the storage of described air duct
The diameter of metal frame 4 is less than the diameter of negative pressure air duct 2, and profile is bullet-shaped, and its top arc end is outside, so as to which air duct is stored
Metal frame 4 is inserted in negative pressure air duct 2, and the bottom of described air duct storage metal frame 4 is connected with montant 6, and described air duct is received
Receive axis and the montant 6 of metal frame 4 and the axis perpendicular of thickening hollow tube 3.
The installation screw 3a of one group of genesis analysis is provided with the shaft for thickening the bottom of hollow tube 3, under installation screw 3a
A fixed pulley 3b is additionally provided with the shaft of the thickening hollow tube 3 of side.On the outer wall of the thickening hollow tube 3 of fixed pulley 3b sides
A horizon bar 3d is also associated with, the capstan winch 5 with the corresponding matching of steel wire rope 1 is additionally provided with horizon bar 3d, in described level
Bar 3d is provided with the installation screw 3a of one group of horizontal distribution.Steel wire rope 1 is wound downwards through cord hole 3a after fixed pulley 3b
On capstan winch 5.
One group of through hole is evenly equipped with the air duct wall at the described air draught end of negative pressure air duct 2（Do not regarded in figure）, in each through hole
In be equipped with iron wire, so as to according to need of work by negative pressure air duct 2 be connected to air duct storage the framework of metal frame 4 on suitable position
Put.
The course of work：
As shown in Figure 3,4, according to working condition actual in drive, the installation on hollow tube and horizon bar is thickeied is passed through
Fixing bolt is set in screw, hollow tube will be thickeied and horizon bar is connected in the frame that fully-mechanized digging machine or fully-mechanized digging machine two are transported, then
By the handle on rocking gear case, air duct storage metal frame is adjusted to suitable height.
Air duct on support bar is stored into metal frame and inserts negative pressure air duct from the air draught end of negative pressure air duct, and by positioned at suction
Iron wire on the air duct wall of wind end in through hole, negative pressure air duct is connected in the framework of air duct storage metal frame.And unnecessary negative pressure
Air duct can produce fold and be deposited in the junction of negative pressure air duct and air duct storage metal frame.
With moving forward and backward for fully-mechanized digging machine, negative pressure air duct can be drawn forward to trail and suspend in midair and receive on a steel cord or backward
Return on air duct storage metal frame outer wall, the simultaneously wound steel wire rope on capstan winch can also be released or withdrawn.
When thus can effectively avoid fully-mechanized digging machine retrogressing in the prior art, negative pressure air duct surplus is more can not be effective
Receive, produce air duct bending section, skew back occurs for air duct under suction, causes air duct ventilation section to strongly reduce, suction air volume drop
Low situation occurs.
In addition, according to the actual conditions in drive, it is also an option that negative pressure air duct connection air duct is stored into metal frame framework
Diverse location on.Because when fully-mechanized digging machine route is more straight, negative pressure air duct is just connected to air duct storage gold
Belong to the rear portion of circle body close to the position of support bar, so that the present invention drives negative pressure air duct, tandem that can be smooth moves；
And when fully-mechanized digging machine route compares bending, then negative pressure air duct is connected to the middle front part of air duct storage metal frame framework, with
Just the present invention drives negative pressure air duct while tandem moves negative pressure air duct can be driven to carry out the front and rear of certain angle again
Curvilinear motion.
