When supporting maintenance, the first screw rod 16 is rotated first, since the first screw rod 16 is to be threadedly coupled with the top of clamp arm 15, first
Bar 16 drives the second cushion 17 to move upwards, so that oxygen analyser 13 is separated with the second cushion 17, then rotates second
The other end of screw rod 24, followed by the second screw rod 24 one end limiting slot 23 internal rotating, due to the second screw rod 24 with hold
Weight plate 12 is threaded connection, therefore the second screw rod 24 pulls second sleeve 21 to move to the right in the inside of sliding slot 22, thus the
Two sleeves 21 pull clamp arm 15 to move to the right by loop bar 18, so that the distance between clamp arm 15 increases, thus can be by oxygen
Gas analyzer 13 is removed between clamp arm 15, then can carry out maintenance to oxygen analyser 13.
According to Fig. 1 and Fig. 3-4, when adhering to more coal dust on filter screen 11, needed at this time by the coal on filter screen 11
Powder is got rid of, to can guarantee that air can enter the inside of oxygen analyser 13 by pipeline 10, can be turned at this time
Turn axis 3, then shaft 3 drives convex block 4 to be rotated, and the part that then convex block 4 protrudes is in contact with the first transverse slat 5, thus
Convex block 4 pushes internal motion of first transverse slat 5 to the second transverse slat 7, while the first elastic element 8 is compressed, and the first transverse slat 5
Hairbrush 6 thereon is driven to move to the right, hairbrush 6 can brush off the coal dust on filter screen 11 at this time, so as to avoid filtering
Mesh on net 11 is plugged, and then unclamps shaft 3, and the elastic force that the first elastic element 8 generates at this time pushes the first transverse slat 5 to the left
Side movement, so that the first transverse slat 5 is restored to original state, consequently facilitating the use of next time.
It is any to be familiar with although the present invention is disclosed as above with embodiment, its protection scope being not intended to limit the invention
The technical staff of this technology changes and retouches made without departing from the spirit and scope of the invention, should belong to this hair
Bright protection scope.

7. a kind of export O for explosion-proof coal pulverizer as of any of claims 1-62The use of on-Line Monitor Device
Method, it is characterised in that: the application method is as follows:
Coal pulverizer ontology (1) shakes when crushing to coal cinder, and oxygen analyser (13) is driven to shake together, at this time
First cushion (14), the second cushion (17) and first sleeve (20) carry out damping, buffering to oxygen analyser (13), from
And avoid the damage of oxygen analyser (13) inner body；When oxygen analyser (13) carry out maintenance, rotation the first
One screw rod (16), since the first screw rod (16) and the top of clamp arm (15) are is threadedly coupled, the first screw rod (16) drive the
Two cushions (17) move upwards, so that oxygen analyser (13) be made to separate with the second cushion (17)；Then second is rotated
The other end of bar (24), then one end of the second screw rod (24) limiting slot (23) internal rotating, due to the second screw rod (24) with
Bearing plate (12) is to be threadedly coupled, therefore the second screw rod (24) pulls second sleeve (21) in the inside of sliding slot (22) direction second
The direction of screw rod (24) is mobile, so that second sleeve (21) be made to pull clamp arm (15) far from oxygen analyser by loop bar (18)
(13), so that the distance between clamp arm (15) and oxygen analyser (13) increase, thus by oxygen analyser (13) from clamp arm
(15) it is removed on the inside of, maintenance then is carried out to oxygen analyser (13)；
When the coal dust adhered on filter screen (11) is more, need to get rid of the coal dust on filter screen (11), to guarantee air
The inside of oxygen analyser (13) is entered by pipeline (10)；Rotating shaft (3) at this time, shaft (3) then drive convex block (4) into
The part of row rotation, convex block (4) protrusion is in contact with the first transverse slat (5), so that convex block (4) be made to push the first transverse slat (5) to the
The internal motion of two transverse slats (7), the first elastic element (8) are then compressed, while the first transverse slat (5) drives the hairbrush at the top of it
(6) it is moved to the direction of filter screen (11), hairbrush (6) then brushes off the coal dust on filter screen (11), to avoid filter screen
(11) mesh on is plugged；Shaft (3) are unclamped later, the elastic force that the first elastic element (8) generates at this time pushes the first transverse slat
(5) it back moves, so that the first transverse slat (5) returns to original state, convenient for the use of next time.
