Description
Technical field
The invention belongs to coal mine roadway driving support technology field, more particularly to for digging anchoring integral fully-mechanized digging machine and Lian Cai
The machine of machine jumbolter independent rack.
Background technology
In the prior art, the support work after roadway driving, is an arduous complicated and extremely inefficient work
Make, main cause is that development machine causes substantial amounts of time waste with the split type work of roof-bolter, and effective time ratio is very
It is small；Not only labour intensity is big manually to beat anchor pole, and the personnel amount for needing is also a lot, thus efficiency is very low, so, need very much
Wanting a kind of machine-mounted roof-bolter can quickly carry out suspension roof support work immediately in development machine driving or after driving, improve driving
The operating efficiency of machine, reduces the labour intensity of operator, improves coal mine production safety.
Independent four arms pick drill carriage, eight arms pick drill carriage, but generally existing complex structure and body are there is also currently on the market
It is larger, limited by span length and ceiling height, multi-frame arrangement is relatively difficult, and in the movement of coal mine down-hole tunnel and logical
The all very poor problem of the property crossed, independent pick drill carriage is wanted to be transplanted on fully-mechanized digging machine front portion relatively difficult, it is also desirable to waste many times
And energy, although some Anchor Care operating efficiencies are improve, a part of labour intensity is reduced, but general effect is not good.
To solve the above problems, the utility model of Application No. CN200620094123.7 discloses a kind of pick anchoring integral
Anchor driving machine, the anchor driving machine is development machine and the mounting structure of roof-bolter one, and roof-bolter is installed on cutting part of heading machine both sides, is utilized
Cutting part of heading machine side is supported and location and installation, institute as roof-bolter mounting platform with cutting part of heading machine side bearing pin
It is slidably matched by being installed on the track of cutting units side between the roof-bolter and development machine stated, roof-bolter is existed by attachment rail
Cutting units sidepiece slide anteroposterior, realizes roof-bolter and cutting part of heading machine integral structure, while using the lifting of cutting units, pendulum
Dynamic and roof-bolter itself function, completes the anchor dress work of roadway bolt.Described roof-bolter has contraction fold mechanism, shrinks folding
Folded mechanism is provided with telescopic oil cylinder and Vertical Cylinders, and telescopic oil cylinder one end is hinged with the bearing pin being installed on track, and the other end passes through
Moving sleeve is hinged with roof-bolter；Vertical Cylinders one end is hinged with roof-bolter, the moving sleeve that the other end drives with telescopic oil cylinder
It is hinged, when development machine works, roof-bolter shrinks and folds, and farthest reduces the bulk of roof-bolter.But, due to this
Utility model is that roof-bolter is installed on into cutting part of heading machine sidepiece, realizes roof-bolter and cutting part of heading machine integral structure
, this structure brings following some problems：One is that the sidepiece that roof-bolter is installed on cutting part of heading machine is influenceed into development machine
The working range of cutting units, also influences sight line of the operator when cut works；Two be cutting units when the work of cut is entered, punching
Hit vibration strongly, the safe operating life of roof-bolter can be had a strong impact on；Three be cutting units when the work of cut is entered, have
Heap is pressed in cutting units when substantial amounts of mineral fragments and dust or roof fall, can cause the damage of roof-bolter；Four is because the practicality is new
Type when needing roof-bolter to work, roof-bolter need by means of cutting units lifting, swing and roof-bolter itself function, complete lane
The anchor dress work of road anchor pole, and a series of operation standard of specifications has been formulated in many collieries in order to keep the safety in production, and carries out Anchor Care work
When making, it is desirable to by development machine all shut down, this do not allow for carry out Anchor Care work when using cutting part of heading machine lifting or
Rotate to coordinate Anchor Care to work, so, the structure of the utility model cannot be operated.
A kind of brill used for coal mine down-hole tunnel Anchor Care of the disclosure of the invention of Application No. CN200610012912.6
Machine.The invention includes hydraulic motor, oil cylinder, holder fixing mechanism, supporting mechanism, feed mechanism and borehole drill construction, and fore-stock is inserted
Enter in the chute of after-poppet, the support guide pillar on fore-stock penetrates the pilot hole on after-poppet；Connect with feed cylinder
The guide plate being integrated, is sleeved in the feeding guide stanchion on fore-stock；Pilot hole on hydraulic motor bearing be sleeved on into
To in guide stanchion.Therefore, all extensible members oil cylinder effect under, along guide stanchion and runner movement.But, the invention
All extensible members are required for setting corresponding guiding parts, oil cylinder only plays dynamic action wherein, and the invention rig is consolidated
The adjustment structure of fixed or operating angle is more complicated, and by screwing or loosening pressed handle, reaches fixed rig or rig work
Make the purpose of angle, operating efficiency is very low, in terms of comprehensive, the inventive structure is complicated, causes structure relatively too fat to move huge, is unfavorable for
Arranged on coal-cutting machinery and narrow space is arranged and used in tunnel.
The content of the invention
