Specific embodiment
Sprocket wheel protective cover plate 5 and pawl 10 are coupled by pin II 13 known to Fig. 1~2, hydraulic cylinder 7 and gusset piece 14
Coupled by pin I6, hydraulic cylinder 7 and pawl 10 are coupled by pin shaft I11, and sprocket wheel protective cover plate 5 and gusset piece 14 pass through pin
III 16 couples, and such hydraulic cylinder 7, pawl 10, gusset piece 10, sprocket wheel protective cover plate 5 constitute crank and rocker mechanism.Wherein
Sprocket wheel protective cover plate 5 is rack, and 6 cranks of hydraulic cylinder, pawl 9, gusset piece 10 are rocking bar.
Be welded by pawl 10 known to Fig. 3~4 by left claw 101, gusset piece 102, right pawl 103, center away from and chain
It is consistent to take turns chain pitch.Left claw 101,103 upper end of right pawl are half concave arc, arc radius R1 >=scraper plate vertical chain ring exradius ruler
Very little R2；Hydraulic cylinder piston rod is connected by pin shaft I11 and pawl 10, is limited with split pin 16.Divide in left claw 101, right pawl 103
It is not welded with left handle 104II, right handle 105II, facilitates worker operation.
By Fig. 1~6 can, sprocket wheel protective cover plate 5 is welded with pipe 51, plate 52, pedestal 53, gusset piece 54.It is welded on cover plate assembly 9
It is connected to pipe 91, arc block 92, handle 93.Pipe 5 is identical with 91 diameter of pipe, and the circular hole on circular hole and pawl 9 on pedestal 53 is straight
Diameter is identical, in order to wear pin shaft.Arc block 92,10 arc radius R2 of radius R1≤pawl, when the mechanism is in inoperative
Under state, arc block 92 is sticked into the circular arc of the leading portion of pawl 10, is played position-limiting action, that is, is guaranteed the safety of the mechanism.
It is welded with left handle I93, right handle I94 on cover plate assembly 9 simultaneously, facilitates worker operation.
By Fig. 5~6 it is found that pawl 10 is fixed together by the plate 52 on fixed pin 12 and sprocket wheel protective cover plate 5, plate
There is threaded hole on 52, can be fixed by fixed pin 12 and plate 52 with M12 bolt, play second layer protection.
By Fig. 3~7 it is found that there is two groups of slotted holes with left handle I93, the right handle I94 to pawl 10 on cover plate assembly 9
Stay out space.9 left handle I93 of cover plate assembly, right handle I94 spacing are L1,10 left handle II 104 of pawl, right handle II
105 spacing are L2, and L1 < L2, such two groups of handles distinguish the enough spaces of phase mutual, convenient for manual operation.
Fig. 8 is that pin 12 is pulled up when in use in operating position of the invention, and cover plate assembly 9 is inverted, and hydraulic cylinder 7 is withdrawn,
Pawl 10 is fallen into the flat ring of chain 4, blocks vertical ring, effectively prevents the reversion of scraper chain.Awaiting Overhaul finishes, hydraulic cylinder 7
Piston rod stretches out, and puts down cover plate assembly 9, then pawl 10 is fixed on sprocket wheel protective cover plate 5 with fixed pin 12.
It is above schematical rather than form by the detailed description that preferred embodiment carries out technical solution of the present invention
On limitation.Those skilled in the art, can be to documented by embodiment on the basis of reading this practical description of the invention
Technical solution is modified or equivalent replacement of some of the technical features, and these are modified or replaceed, and does not make
The essence of corresponding technical solution is detached from the range of technical solution of the present invention.
