Machine, belongs to two-wheel flute milling machine technical field.
Background technology
Continuous wall trench underground construction two-wheel flute milling machine is that by transmission case, power of getting on the bus is transferred to milling wheel, makes milling wheel
Rotation, reaches the purpose of milling broken formation.Two-wheel flute milling machine adapts to stratum extensively, especially constructs in ground consisting of hard rock, more can highlight
Its efficiency of construction and economy.In the course of work, transmission case is in mud all the time, and mud pressure is transferred deeply with transmission case
Degree increases and increases.On the one hand, transmission case need to provide fixing support to each driving parts, on the other hand need to export rotation again, drive
, therefore, between the fixing support function of transmission case and output spinfunction, there is rotatory sealing technical problem in dynamic milling wheel work.This rotation
Turning sealing not only needs to prevent the oil leakage of transmission case body internal gear, and bigger difficult point is to be constantly in pressure full of rock
In the mud of bits, there is the ability preventing slurry compounding transmission case.Once it is unreliable or because abrasion leads to sealing property
Sealing property lost efficacy, after mud enters whole transmission case, it will destroy bearing in transmission case, the part such as gear, user must not
It is changed without a whole set of transmission case, cause huge economic losses.
At present, on domestic market existing continuous wall trench underground construction two-wheel flute milling machine with the precious high Double-wheel milling of import Germany
Based on scouring machine, user's repacking simple type two-wheel flute milling machine of minority.The transmission case of these two-wheel flute milling machines exports milling wheel with both sides
It is and communicate structure.If internal gear oil leakage or slurry compounding problem occur, it will related impact at any one side milling wheel
The parts such as the bearing in transmission case and opposite side milling wheel, gear, maintenance cost is high.
Content of the invention
The problem existing for above-mentioned prior art, the present invention provides a kind of isolated two-wheel flute milling machine transmission case, passes through
Transmission case and both sides milling wheel are designed to isolated space, and carry out independent sealed.If occurring internal at any one side milling wheel
Gear oil leakage or slurry compounding problem, do not interfere with the parts such as bearing in transmission case and opposite side milling wheel, gear, significantly drop
Low maintenance cost, cost performance is high and easy to maintenance, and suit large area to popularize application.
To achieve these goals, the present invention adopt a kind of isolated two-wheel flute milling machine transmission case, including transmission case body,
Actuating unit, drive sprocket, driven sprocket, support base, milling wheel reductor, milling wheel, bearing block, bearing and rotary, be resistant to
The sealing of pressure and seal receptacle, actuating unit is fastened in transmission case body；Drive sprocket is arranged on the output end of actuating unit,
And rotated by chain drive driven sprocket, driven sprocket drives the rotation of milling wheel reductor, and milling wheel reductor output torque is passed through
Shock ring drives milling wheel rotary work；Described driven sprocket is fixedly mounted under transmission case body by the bearing of both sides, bearing block
On the support base of side, it is separately installed with seal receptacle and sealing outside bearing block, sealing is joined with driven sprocket output shaft periphery
Close and realize sealing, thus transmission case body inner space is isolated with both sides milling wheel reductor inner space, formed isolated
Independent sealed space.
Preferably, the fixing end of described milling wheel reductor is mounted on support base, installs end face and is designed with static seal；
Milling wheel output end of reducer is rotated against with milling wheel reductor fixing end, is designed with sealing between the two, can be by milling wheel reductor
Inner space keeps apart in extraneous mud, is effectively sealed.
Preferably, described actuating unit includes motor and reductor, and reductor is arranged on the output end of motor, reductor
Output end is connected with drive sprocket.
Compared with prior art, the present invention passes through to design rotary, can be pressure sealing and seals holder structure by transmission case
Keep apart with both sides milling wheel so that each milling wheel space is independent, and be not communicated with transmission case inner space.If wherein one
Oil leak occurs at individual milling wheel or enters mud problems, will not affect that the parts such as bearing in transmission case and opposite side milling wheel, gear,
Greatly reduce maintenance cost.Meanwhile, in milling wheel reductor fixing end and support base, end can be installed and be designed with static seal,
It is designed with sealing, by milling wheel reductor inner space and extraneous mud between milling wheel output end of reducer and milling wheel reductor fixing end
Slurry is effectively kept apart, and effectively prevents extraneous mud to enter in milling wheel reductor, and prevents the tooth in milling wheel reductor
Leakage in wheel oil.
