9 in use, and the main force part of abaculus slot 14 is four stopping tables, when stress, with 8 two sides empennage of second connecting portion
Contact surface cuts product in 7.35cm2More than, the empennage stress sectional area of second connecting portion 8 is 12cm2, stopping table sectional area is
12cm2, link block 2 and the born shearing force of 14 stopping table of abaculus slot are respectively 1320KN, 1800KN, and institute's bearing capacity is greater than hydraulic
Maximum, force when bracket elapses, bearing capacity suffered by weak part is higher than link block 2 at abaculus slot 14, therefore its main force part is non-
Weak part.The empennage of 8 two sides of second connecting portion, chute 9 is closely joined together, therefore second connecting portion 8 is " work " shape
Structure meets the pivot angle demand in use process.
Scheme is advanced optimized, to make link block 2 in underground normal use, link block 2 is using high-intensitive, high-ductility alloy
Material forges, and in 1200MPa or more, 2 horizontal direction of link block is primarily subjected to elapse because hydraulic support works tensile strength
With draw move when bring shearing force, hydraulic support tractional force generally in 633~989KN, move frame Shi Layi power generally 409~
716KN, link block 2-1 horizontal direction most weak part average cross-section 9.486cm2, yield strength 1100MPa can bear to cut
The cm of shear force F=S × σ=9.4862×11000Kg/cm2=104346Kg ≈ 1043KN, institute's bearing capacity are elapsed greater than hydraulic support
When maximum, force, meet underground use.
With reference to Fig. 5-7, the utility model provides a kind of chuting system, including several chutes 9 and several chutes 9 of connection
Chute attachment device, wherein chute 9 includes bottom plate 10, and 10 side of bottom plate is provided with baffle 11, and the other side is provided with shovel
Board slot side 12, the top of bottom plate 10 is arranged in parallel with middle plate 13, and the both ends of baffle 11 and shovel board ledge 12 are symmetrically arranged with
Abaculus slot 14, the abaculus slot 14 of adjacent chute 9 are adapted after docking with link block 2, and middle 13 both ends of plate are equipped with L-shaped groove, make adjacent
The middle Board position adjacent after docking of chute 9 forms the gap being adapted with hyoplastron 1, the insertion for hyoplastron 1.
Scheme is advanced optimized, chute 9 in use, produces between link block 2 and baffle 11 or shovel board ledge 12
Raw friction, when coalcutter is mined, coal cinder in falling on plate 13 while also can generate friction with hyoplastron 1, therefore middle plate 3 is
Rolled plate, while wear-resistant coating is smeared on middle plate 3, link block 2 and hyoplastron 1, the service life of attachment device can be improved.
The utility model is creative independently to separate at the vulnerable position of chute 9 with chute 9, changes from structure original
The type of attachment of chute thoroughly solves male connector breakage problem.After two section chutes 9 are to getting well, hyoplastron 1 is inserted into two section chutes first
At the gap that 9 middle plate 13 connects, secondly link block 2 is put in the abaculus slot of chute two sides, and is assembled with hyoplastron 1, makes to connect
It connects the intermediate connecting hole 4 of block 2 to be aligned with hyoplastron both ends insertion hole 5, finally fix at both ends with positioning pin, then install split pin and prevent
Only positioning pin is scurried out from connecting hole 4.
The utility model is most weak straight down since link block 2 uses high-intensitive, high-ductility alloy material to forge
Position sectional area is equivalent to diameterDumbbell, for tensile strength in 1200MPa or more, ability to bear is complete
On common dumbbell, dumbbell can be substituted completely；2 horizontal direction of link block is primarily subjected to work because of hydraulic support passage and drawing shifting
When bring shearing force, hydraulic support tractional force moves frame Shi Layi power generally in 409~716KN generally in 633~989KN,
2 horizontal direction of link block most weak part average cross-section 9.486cm2, yield strength can bear shearing force F=in 1100MPa
The cm of S × σ=9.4862×11000Kg/cm2=104346Kg ≈ 1043KN, institute's bearing capacity are greater than maximum when hydraulic support elapses
Power meets underground use.
The main force part of the utility model abaculus slot 14 is four stopping tables that abaculus slot 14 and link block 2 connect, only
Product is cut in 7.35cm with the contact surface of 2 two sides empennage of link block when mouth platform stress2More than, 2 empennage stress sectional area of link block is
12cm2, stopping table sectional area is 15cm2, link block 2 and the born shearing force of 14 stopping table of abaculus slot be respectively 1320KN,
1800KN, institute's bearing capacity are greater than maximum, force when hydraulic support elapses, and bearing capacity suffered by weak part is higher than connection at abaculus slot 14
Block 2, therefore its main force part is non-weak part.And two section chutes are closely attached to one by the empennage of 2 two sides of link block
It rises, meets the pivot angle demand in use process, each stress surface of link block 2 has forging and divides film surface, divides film surface to have and changes
The effect of Impact direction, reaction force when it is by coalcutter gravity and coal mining are distributed to each connector, avoid because of part
It is damaged caused by stress is excessive.
For the utility model chute under extreme stress condition, main stress weak part is link block 2,2 cost of link block
Low, replacement is convenient；Hyoplastron 1 can be different with working face height in chute, and automatic adjusting position guarantees smoothed when equipment operation
It crosses, reduces scraper plate running resistance, effectively prevent extreme stress caused by mixing because of scraper plate with scrapper conveyor card, reduce scrapper conveyor
Probability of damage, increase scrapper conveyor service life.
