Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model is made further elaborate and
Explanation.
Please refer to Fig. 1 to Fig. 3, in an embodiment, a kind of open cylinder is oriented to rack rails 10, including guided way 100, pin row
200, mounting ear 300 and coalcutter guide post 400, the pin row 200 are set to the side of the guided way 100, the installation
Ear 300 is set to the bottom of the guided way 100, and the coalcutter guide post 400 is set to the guided way 100 away from described
The side of pin row 200, the guided way 100 are strip, and the pin row 200 includes several along the 100 length side of guided way
Lower coal space 211 is formed to the pin tooth 210 of word order, between the pin tooth 210 of adjacent two；The pin row 200 with
210 bottom of the pin tooth of 300 relative position of mounting ear is connected as one, and forms coalcutter dashpot 212.Coalcutter exists
During walking on the open cylinder guiding rack rails 10, coalcutter guiding boots are sheathed on the coalcutter guide post 400
On, the traveling wheel of coalcutter is engaged with the pin row 200, and coal breakage is fallen when on open cylinder guiding rack rails 10, coalcutter
200 engagement place of traveling wheel and the pin row the lower coal that is formed between two adjacent pin tooths 210 of cinder
Space 211 is fallen on drag conveyor, and the arragement construction of open pin row is conducive to walking wheel of coal cutter and nibbles with pin row 200
The unobstructed blanking of material for closing between cog, overcomes the rack rails of traditional half-packaging since secondary side plate is arranged, caused by coalcutter row
The problem for walking the material discharge difficulty that wheel engages between cog with drag conveyor pin row is prolonged to advantageously reduce equipment attrition rate
The service life of long equipment.Further, there are biggish torsions between the traveling wheel of coalcutter and the pin row 200 in order to prevent
The pin row 200 is connected as one, described in formation by square in 210 bottom of the pin tooth with 300 relative position of mounting ear
Coalcutter dashpot 212, the traveling wheel of coalcutter obtain a upward support when by the coalcutter dashpot 212
Power offsets part torsion, further reduced equipment loss, but also coalcutter is on the open cylinder guiding rack rails 10
Run more unobstructed, raising coal mining efficiency.
It is oriented to the stability run on rack rails 10 to further increase coalcutter in the open cylinder, one preferably implements
In example, the mounting ear 300 includes main ear 310 and auricular appendage 320, and the main ear 310 is set to the guided way 100 and the coal
The bottom of 400 junction of machine guide way, the auricular appendage 320 are set to 212 bottom of coalcutter dashpot, with the main ear
310 are oppositely arranged, and the main ear 310 runs through with the auricular appendage 320 offers rack rails seat mounting hole 321.By the open circle
Column guiding rack rails 10 is installed on the rack rails seat of tube sheet conveyer crossheading, passes through the rack rails seat mounting hole 321 by pin shaft, right
The open cylinder guiding rack rails 10 is fixed, due in the present solution, the fixed form of ears is used, so mining
When machine passes through, the open cylinder guiding rack rails 10 and rack rails seat two sides uniform force avoid being oriented to due to open cylinder
There are larger torsion between rack rails 10 and rack rails seat, the coalcutter for leading to the damage of pin shaft or the engaging lug 300, while also making
It runs more steady.
Have in a preferred embodiment, the coalcutter guide post 400 be it is cylindric, section be a minor arc, the coal mining
The highest point of machine guide post 400 is higher than the upper surface of the guided way 100, the coalcutter guide post 400 and the guided way
The two sides of 100 junction form symmetrical two guiding boots guiding groove 401 to contract.Coalcutter guiding boots are sheathed on institute
On the outer surface for stating coalcutter guide post 400, and the both sides of coalcutter guiding boots are fallen into the guiding boots guiding groove 401, into
And the sliding for enabling coalcutter guiding boots uniform and stable in the coalcutter guide post 400, avoid leading for traditional square
It is in the coalcutter guiding excessively serious abrasion of boots in corner angle to column, reduces the service life of equipment.Secondly as the coal mining
The presence of machine guide post 400 and two guiding boots guiding grooves 401, there are also the functions of automatic capturing and coalcutter to be oriented to boots
Adaptively the center of circle can be found accurately in the coalcutter guide post 400, to ensure that the even running of coalcutter, further
The torsion reduced between walking wheel of coal cutter and the pin row 200, reduce equipment loss, extend service life of equipment.
In one specific embodiment, the central angle for the minor arc that the section of the coalcutter guide post 400 is formed is 195 °~
270 °, to guarantee that coalcutter guiding boots normally steadily slide.
Further, the central angle of the guiding boots guiding groove 401 is 90 °~150 °, de- to avoid coalcutter guiding boots
Rail.
A kind of mine flight conveyer crossheading, including shovel board ledge, baffle, middle plate, bottom plate and rack rails seat, the shovel
Board slot side is oppositely arranged with the baffle, and the middle plate and the bottom plate are set to the shovel board ledge and the baffle plate groove
Between side, the rack rails seat is fixed on the baffle, further includes open cylinder guiding rack rails 10 as described above, institute
It states open cylinder guiding rack rails 10 to be installed on the rack rails seat, so that coalcutter is on the mine flight conveyer crossheading
The stability that coalcutter is walked on the mine flight conveyer crossheading is effectively guaranteed in stabilized walking, reduces equipment damage
Consumption improves coal mining efficiency.
Above disclosures are merely preferred embodiments of the utility model, the utility model cannot be limited with this certainly
Interest field, those skilled in the art can understand all or part of the processes for realizing the above embodiment, and according to this reality
