Description
The invention provides a kind of draw off gear that is used for the supply cable of mobile in the venue all kinds of machineries, belong to the B65H75/00 technical field in the International Patent Classification (IPC).
Current, at widely used transfer crane, loader-unloader on the bucket-wheel stacker reclaimer, all needs to be equipped with the supply cable wind2.By this device folding and unfolding cable, when walking in the venue to adapt to this class machinery to the change in location requirement of power supply.Though complete machine is because of purposes and exert oneself variedly, the basic comprising of cable reel installation all is three parts, i.e. reel, engine installation, transmission device.Because cable successively takes in or emits, that is to say that twining radius changes on reel.This changes the applied moment of reel with regard to causing cable.Again since complete machine be average rate walking and the velocity of rotation of reel is constantly to change, therefore need to solve the moment between engine installation and the reel and the coordination problem of revolution.
In prior art, for adapting to the variation of suffered cable applied moment of reel and revolution, two kinds of reel drive forms are arranged: a kind of moment and revolution that is engine installation itself is exported is transformable.The moment and the revolution that make output torque and revolution and cable impose on reel change synchronously.Realize engine installation even, stable and driving with this to reel.That adopts this form has torque motor (as No. 91208597.5 Chinese patent), a HM Hydraulic Motor (as the 4th, 114, No. 827 US Patent).Another kind of mode is that revolution, the output torque of engine installation fixed, and only realizes differential (the autodyne damping type cable reel installation that provides for No. 91222785.3 as Chinese patent) between reel and engine installation by transmission device.
But above-mentioned several structures all exist tangible limitation separately in the prior art.Though as adopt HM Hydraulic Motor directly bending moment, speed governing, complex structure, measure of precision require high, manufacturing cost and use cost is much bigger.Though the revolution and the moment that adopt torque motor also can obtain changing, the torque motor stall time be shorter, and (generally being no more than 5 minutes) current does not still have desirable time-delay way.The travel distance that this has just limited complete machine makes the work protection face very little, can not satisfy the need of work in big place.Adopt the aforementioned autodyne damping type cable reel installation that provides, only have differential function, but moment is unmodified in the course of the work, thereby cable is stressed remains uneven, all very unfavorable to cable self and coiling work.
At the above-mentioned problem that needs solution in the prior art, the invention provides a kind of driving device.Its objective is the fixedly revolution of common motor output and torque after this device is handled, export bending moment, the differential power that can corresponding reel be subjected to the variation of cable tension Changing Pattern from this device again.
Design philosophy of the present invention is: still adopt in the prior art mode of friction transferring power so that the moment of utilizing differential effect that the slip of friction member realizes and the pressure that changes friction lining just can directly change to be transmitted make things convenient for condition.On this basis, with a cover underaction mechanism, according to the Changing Pattern of the suffered cable tension of reel, the compression of coordination and loosen to make and produce pressure and pressure spring between friction lining is formed with the tor-con of bending moment function.Its concrete structure is: with the garden dish friction lining that a cover is coaxially set, transmitting torque.With dynamical axis directly link to each other for rotating plate, by the rotating plate friction-driven is driven disc.What master and slave friction lining was alternate establishes some.Simultaneously rotating plate group or driven disc group are designed to the form that can move axially, establish pressure spring thereafter.Behind spring, establish an axially displaceable gear.The move forward and backward axis hole and the gear wheel shaft that can adopt gear of gear have the screw thread that matches, and when gear rotates, promote gear.Because this gear is used for compressing or loosening pressure spring, be that pressure is adjusted gear so name.The rotation that pressure is adjusted gear is easy to realize, only need establish a helper motor (claiming the tor-con work drive motor herein).Just passable through one group of reducing gear.What need in addition to mention is exactly: move because pressure is adjusted gear, so the drive wheel of this gear of direct drive need be made long garden cylindricality.In addition, the revolution of pressure adjustment gear will be according to diameter that gives selected earlier cable specification and reel and footpath, the end, reel is provided with numerical value and the rate of change of the determined cables of parameter such as height to reel institute application of force square, again through the ratio of revolution of reductor, the parameters of driving machine revolution friction lining, spring is converted into rise, the begin position and the moving velocity of gear compression spring, and the axis hole spiral shell square with pressure adjustment gear resolves into revolution at last.There has been pressure to adjust the revolution of gear revolution and the tor-con work drive motor of selecting, just can have designed the reduction ratio and the corresponding number of gears of tor-con train of reduction gears.
For the ease of making, install and transferring power reposefully, friction lining, spring, the pressure that will constitute tor-con are adjusted gear, and reducing gear installs with a housings close.In housing, friction lining, spring, pressure are adjusted gear and is coaxially set.It is a sleeve-like that pressure is adjusted gear wheel shaft.It is outer and be fixed on the housing to be enclosed within Power Available Shaft.The tor-con work drive motor is installed, reducing gear in the drive shell on housing.Simultaneously whole tor-con and reel drive motor, drg, reductor coaxial line are installed.Just finished the mechanics of whole cable reel installations to this.After having finished mechanics, the bidirectional switch of tor-con work drive motor is installed again, commutation limiting device and control complete machine movable motor, the reel drive motor, the switch of tor-con work drive motor switching simultaneously, more than promptly finish whole technology of the present invention and constitute.Working process of the present invention is: when whole machinery by place one end when walk in the centre, need the reel take-up, the moment that this moment, cable imposed on reel increases gradually.The reel drive motor is in running state.Drg is decontroled.Power is through friction lining, reductor, and chain, driving reel rotate take-up.Simultaneously, the tor-con work drive motor rotates to the direction of compression spring, and pressure is adjusted gear and moved to the friction lining direction in rotation process, compressed pressure spring, the moment simultaneous growth that makes friction moment between friction lining and cable impose on reel.When complete machine operation beginning to leave place is middle, becomes and make payout process.This moment, limit switch made cutting out of reel drive motor, drg braking, active friction plate stall.Cable pulling reel overcomes the friction lining resistance and rotates, and emits cable.The tor-con work drive motor rotates through change-over swith commutation, and pressure spring is loosened gradually, and the friction moment between friction lining reduces gradually, and appropriate cable is drawn close and the applied moment that diminishes to the reel axle center.
Use good effect of the present invention to be: not only realized the differential effect of friction lining type of belt drive, and when driving reel take-up and reel and overcome the resistance cable laying, required and moment that overcome all to be the moment that imposes on reel with cable, changes synchronously.The stabilized uniform that has guaranteed cable is stressed, is unlikely to cause to skid or pull cable.This has just obtained with the simplest mechanical system, has solved for a long time unsolved thorny problem of folding and unfolding cable installation.
