Description
Technical field
The utility model belongs to coal mine machinery equipment field, is related specifically to a kind of high inclination-angle gob side entry retaining holder connection dress
It sets.
Background technology
Gob side entry retaining is one of the principal mode of no coal pillar mining technology, is tieed up along mined out area edge after coal working face
The former stope drift active workings of shield, using certain technological means make the crossheading of a upper section again supporting pour one of diaphragm wall leave for it is next
A section is used as return aircourse.Its advantage mainly improves coal recovery rate, reduces tunnel amount, reduces cost of ton coal, prolongs
Long mine service-life alleviate the contradiction of excavation replacement anxiety.Be conducive to mine safety production and improve mine technology economy effect
Benefit, in the research application of decades, the success in the field with unsuccessfully and deposit, be applied to some condition of coal seam occurrence substantially
Mine good, working face inclination angle is small.Gob side entry retaining holder is divided into side arm and after-frame, side arm type with force piece effect,
Play supporting and passage scrapper conveyor, after-frame then mainly provides reliable safety operation space to make diaphragm wall, plays branch
Shield and gear cash effect, and realization walking is mutually pushed and pulled with side arm.In large inclination working surface, since the component that equipment glides increases,
Especially after-frame usually causes side arm to wag the tail, causes entire working face branch during drop frame is tried to stop people from fighting each other since downslide component is larger
Frame, which generates, squeezes frame, and side arm can also pushed away in pushing and sliding by scrapper conveyor and tiltedly scraper conveyor middle groove is caused to damage.Therefore original side arm
The exploitation that large inclination working surface is not suitable for after-frame connection type uses.
Invention content
The purpose of this utility model is：Overcome the shortcomings of the prior art, a kind of high inclination-angle gob side entry retaining is provided
Holder coupling arrangement, meeting the forward and backward frame of gob side entry retaining holder can be coupled to each other in large inclination working surface, and solve side arm holder
The problem of wagging the tail.
What the technical solution of the utility model was realized in：A kind of high inclination-angle gob side entry retaining holder coupling arrangement, mainly
Including side arm set cap, side arm top beam connection otic placode, horizontal connection ear, vertically couple ear, after-frame top beam connection otic placode, holder
After-frame top beam, perpendicular pin, key seat, U-shaped card, lateral pin, backing pin cylinder, backing pin plate, middle muscle, side muscle, reinforcing rib, it is characterised in that side arm top
Beam connection otic placode is horizontally disposed and increases vertical hinge hole, is welded on side arm set cap, after-frame top beam connection otic placode is vertical
Horizontally hinged hole is arranged and increased, is welded on holder after-frame top beam, vertical hinge hole is disposed on level connection ear, and by pin
Seat welds therewith, and the vertical ear that couples is disposed with horizontally hinged hole, and backing pin cylinder is welded therewith, and level connection ear couples with vertical
Ear is welded as a whole, and side arm top beam connection otic placode is coupled ear with level using perpendicular pin couples, and is fixed perpendicular pin with U-shaped card, profit
After-frame top beam connection otic placode is coupled into ear connection with vertical with lateral pin, is fixed lateral pin with backing pin plate.
A kind of high inclination-angle gob side entry retaining holder coupling arrangement provided by the utility model is used in big angle coal face
When, after-frame top beam otic placode is hinged by lateral pin and gob side entry retaining holder coupling arrangement, and side arm top beam otic placode is by perpendicular pin and along sky
It stays lane holder coupling arrangement hinged, can realize left-right rotation and realize and rotate upwardly and downwardly, the free shape of hinged realization with side arm
State does not interfere with side arm completely during after-frame drop frame is tried to stop people from fighting each other, and after the adjustment rack-like state when, will not because with it is preceding
Frame does not have larger degree of freedom and can not adjust.
The utility model has the beneficial effects that：Original gob side entry retaining holder is solved in large inclination working surface because that can not adjust
After-frame and influence side arm, so that the downslide component of after-frame is all acted on side arm tail portion makes side arm wag the tail, and causes to squeeze frame and damage and scrape
The technical barrier of trigger intermediate channel, the utility model is simple in structure, using reliable, overcomes the deficiency of original structure.
