Background technology
At present, diamond-wire saw is mainly used in marble mine exploitation, the shaping of waste material and cuts apart and the processing and other fields of shaped stone material, and these are all process operations on land, thereby its drive unit is also applied to land, at present, be not still applicable to being applied to drive unit under water.But along with the exploitation of Underwater resources, the especially exploitation of offshore oil, at some occasion (as sea-bottom oil-gas pipeline maintenance activity), also needs to use under water diamond-wire saw.
When diamond bead string rope cuts workpiece, must have drive unit that motion and the power of bead string rope are provided, only, under suitable drive unit effect, bead string rope just can complete work piece cut work.The main motion of diamond-wire saw is the shuttling movement of bead string rope.Bead string rope supports formation closed-loop along driving wheel and directive wheel, is driven and is realized shuttling movement by driving wheel.Driving wheel adopts the type of drive of hydraulic pressure, directly drives drive sprocket axle to rotate by hydraulic motor.
Be subject to the restriction of size, shape and the cut material of seabed working environment, cut material, just must there is the bead string rope drive unit being applicable to for this condition of work and requirement, and be all not suitable for being applied under water for the tensioning apparatus of land at present, therefore, need to a kind ofly can be applied under water and meet rope saw and bead string rope be driven to the drive unit requiring.
Summary of the invention
The purpose of this utility model is to provide a kind of drive unit of the saw of restricting, and this apparatus structure is simple, easily operation of installation, reliable, bears sealing load large, can be applied under water and meet rope saw bead string rope is driven to requirement.
For achieving the above object, the utility model takes technical scheme as follows:
The restrict drive unit of saw, is characterized in that: this device comprises: be arranged on bearing block, gear motor, driving wheel and live axle on fixed mount, be provided with bearing in bearing block; One end of live axle and bearing fit are installed, and the other end is connected with driving wheel secure fit with cover baffle plate by driving wheel borehole jack; End face of flange and the bearing block of gear motor are located by connecting, and the axle of gear motor and the stomidium of live axle are connected; Between bearing block one end and hubcap, be provided with the general plug of special Kang Xuanzhuan that plays underwater sealing effect; Between the bearing block other end and the end face of flange of gear motor, be provided with the O shape circle that plays underwater sealing effect.
In the utility model, described gear motor is hydraulic motor, and driving wheel adopts the type of drive of hydraulic pressure.Hydraulic motor is relatively suitable for underwater operation, and not only lightweight and volume is little for it, and underwater sealing and stepless time adjustment are also easy to realize.Described hydraulic motor carries out stepless speed regulation between 500～2500r/min.
The other end of live axle is connected with driving wheel secure fit with cover baffle plate by driving wheel borehole jack, and by hexagon-headed bolt and washer locking, and by the transmission campaign of driving wheel flat key and moment of torsion.
In order to ensure the excellent sealing of rolling bearing pedestal inner chamber, the utility model is provided with potted component in the joint of bearing block and end cap and motor flange, plays underwater sealing effect.
Compared with prior art, the utlity model has following advantage:
1, the utility model in the course of the work hydraulic motor be the critical elements of drive unit, the service behaviour of hydraulic motor is directly connected to operating efficiency and the stability of main motion system and whole rope saw, gear motor not only has the advantages such as operating pressure is high, volumetric efficiency is high, starting torque is little, long service life, but also it is high to have reliability, with advantages such as lightweight and volume under power are little.
2, the utility model adopts the general plug of special Kang Xuanzhuan and O shape circle combination sealing, effectively plays underwater sealing effect.Simple in structure, easily operation of installation, reliable, bear sealing load large.
3, in the utility model, driving wheel adopts the type of drive of hydraulic pressure, directly drives drive sprocket axle to rotate by hydraulic motor.Hydraulic motor is relatively suitable for underwater operation, and not only lightweight and volume is little for it, and underwater sealing and stepless time adjustment are also easy to realize.In hydraulic control system, utilize flow speed control valve can between 500～2500r/min, carry out to hydraulic motor stepless speed regulation.
The utility model can be applied under water and meet rope saw bead string rope is driven to requirement.
