Description
Technical field
The present invention relates to the star-wheel that one of tunnelling machine technical field is used for tunnelling machine shipment activity drives
Device.
Background technology
At present, tunnelling machine to can cut the unidirectional comprcssive strength of coal petrography requirement increasing, running into hardness relatively
During high coal petrography, through the method frequently with big gun pick, big gun pick is not only dangerous high, and do mechanization operation stops, when wasting a large amount of
Between, affect work efficiency；And some operating modes does not allow big gun to dig, if selecting to bypass this coal petrography region, which adds work
Measure and decrease the exploitation of Ore；Can be with the heavy tunnelling machine of cut hard rock although its cutting capacity if selected
By force, but its weight and overall dimensions are larger, the tunnel scope that such tunnelling machine adapts to is less.Therefore research and develop a kind of using
Star-wheel-drive device in tunnelling machine shipment activity is always new problem anxious to be resolved.
Content of the invention
It is an object of the invention to provide a kind of star-wheel-drive device for tunnelling machine shipment activity, lane can be made
Road development machine has lower fuselage height, and not only security and stability during increase tunnelling machine cut hard rock is it is also possible to allow
Tunnelling machine adapts to more operating modes；The thinner shovel board portion of thickness can be laid out, make tunnelling machine more thorough
Clear the clout on base plate, and then reduce the resistance that base plate material produces when whole machine advances.
The object of the present invention is achieved like this：A kind of star-wheel-drive device for tunnelling machine shipment activity, bag
Include by star-wheel, the first bolt, the first packing ring, floating bearing, steel plate, the second bolt, second packing ring, sealing ring, motor base, hydraulic pressure
Motor, the 3rd bolt, the 3rd packing ring, sealing strip, rotating disk, the 4th bolt, the 4th packing ring, the 5th bolt, in the shovel of development machine
Two identical star-wheel-drive devices are symmetrically installed on plate portion, outside the straight mouth of motor, have sealing ring, hydraulic motor passes through the 3rd
Bolt and the 3rd packing ring and couple with motor base, inside the groove that shovel board portion is formed, the outer ring of floating bearing passes through the 4th to motor
Bolt, the 4th packing ring is linked up with motor base, and star-wheel passes through the first bolt, the first packing ring is coupled with rotating disk, and rotating disk is led to
The inner ring crossing the 5th bolt, the 4th packing ring and floating bearing passes through bolt-connection, and steel plate is passed through the second bolt, and second packing ring joins
It is connected in rotating disk, equipped with sealing ring between rotating disk and motor base.
The structure being characterized by it of the present utility model.Its operation principle is to substitute original double circle using floating bearing
Cone roller bearing adds support and the positioning of floating seal and locking nut, and floating bearing to carry sealing easy to maintenance and more may be used
Lean on.
A kind of star-wheel-drive device for tunnelling machine shipment activity compared with prior art, has drive mechanism letter
Single reliable, sealing is safer, trouble point is few, the maintenance time of reduction workman, the advantages of more thoroughly clear bed material, will widely
It is applied in tunnelling machine technical field.
Brief description
Below in conjunction with the accompanying drawings and embodiment is described in detail to this utility model.
Fig. 1 is top view of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Specific embodiment
Referring to the drawings, a kind of star-wheel-drive device for tunnelling machine shipment activity, including by star-wheel 1, the first spiral shell

3rd bolt 11, the 3rd packing ring 12, sealing strip 13, rotating disk 14, the 4th bolt 15, the 4th packing ring 16, the 5th bolt 17, in pick
Enter to be symmetrically installed two identical star-wheel-drive devices in the shovel board portion of machine, outside the straight mouth of hydraulic motor 10, have sealing ring 13,
Motor 10 is passed through the 3rd bolt 11 and the 3rd packing ring 12 and is coupled with motor base 9, and motor 10, inside the groove that shovel board portion is formed, returns
The 4th bolt 15 is passed through in the outer ring that rotating shaft holds 4, and the 4th packing ring 16 and motor base 9 link up, star-wheel 1 by the first bolt 2, the
One packing ring 3 is coupled with rotating disk 14, and rotating disk 14 is passed through by the 5th bolt 17, the 4th packing ring 16 and the inner ring of floating bearing 4
Bolt-connection, steel plate 5 is passed through the second bolt 6, second packing ring 7 is connected in rotating disk 14, between rotating disk 14 and motor base 9
Equipped with sealing ring 8.
