The comformability of cable winch is comparatively strong, and the object of the relative movement connected is general without fixing moving track or route (marine locator that such as scientific investigation ship pulls).If it is installed on mobile object, except moving without except fixing moving track or route of mobile object itself, the non-moving object that the cable that its reel is released connects generally also often changes (such as bank electric feed boat-carrying cable winch).For adapting to the working condition without certain tracks, cable winch needs manual intervention to operate.Cable winch requires higher to the guiding of removal cable, and the reel one general configuration strand oscillator of winding removal cable, also configures other guide piecees sometimes.
Background technology
Very large space is had in the reel of cable winch.In order to make facility compact, carbon brush-slip ring group is generally installed in reel.Carbon brush-slip ring group belongs to slip electrical contact on electrically, and carbon brush is easily-consumed products, needs to open reel periodic inspection and safeguards, generally need the end plate of reel side to make detachable end.Reel operationally has rotation, therefore needs to support reel and facilitates it to rotate.The most two ends of current reel all adopt axle head to support, and namely on the center shaft of reel, install bearing, and reel is arranged on base by bearing, and base is by the weight of the bearings reel on drum center axle.Axle head supports the dismounting hampering winding drum end cover, need remove axle head and support the end cap can opening reel.This can cause very large trouble to the Inspection and maintenance of carbon brush-slip ring.
Summary of the invention
In order to solve the Inspection and maintenance problem of carbon brush-slip ring group, reel one end of the present utility model still uses axle head to support, and the other end adopts support roller to support.Use support roller support to hinder and open winding drum end cover, like this, just can keep in repair the device in reel easily.
The main portion that support roller supports is two support rollers and a wheel rim.Support roller is installed in the side-lower at winding drum end cover place, each one of the left and right of spool axis.Near end caps on reel, installing wheel rim.Two support rollers and wheel rim keep good Structure deformation, support the weight of this end of reel.The angle that the center of two support rollers is formed drum center is generally between 45 °-120 °.Unless special requirement, the vertical central plane of two support rollers to reel is generally arranged symmetrically with, and forms stable triangle.
The driving of reel can use conventional axle head to drive.In that driving mode, CD-ROM drive motor drives spool spindle to drive reel by reductor.If now use the reductor of band hollow shaft, one end of drum center axle can be penetrated the hollow shaft of reductor, the bearing using reductor supports to realize axle head.
Also reel can be driven by driving support roller.In that driving mode, support roller and wheel rim process profile of tooth, intermeshes.Motor drives toothed support roller to drive toothed wheel rim to drive reel by reductor.
In order to make removal cable reel neatly on reel, the cable on reel is by strand oscillator folding and unfolding.Strand oscillator is also by the transmission system drives of reel: in spool spindle, install drive sprocket, by chain-driving driven sprocket, drives strand oscillator leading screw to rotate, drives strand oscillator to coordinate the folding and unfolding synchronizing moving of cable on reel.
When removal cable is very long, if to reel one deck as cable drum on reel, then reel volume will be very large, can consider multilayer-wound cable on reel for this reason.When reel last layer cable is after expiring, need cable to be continued be wound on this layer of cable, now reel need continue to rotate by former direction, synchronously driven leading screw also continues to rotate by former direction, but strand oscillator needs oppositely mobile back winding displacement, and general one-way spiral leading screw can not realize these needs.The utility model uses two-way leading screw to drive strand oscillator, can solve commutation problem.
On two-way leading screw, be carved with left-handed and dextrorotation two kinds of screw threads across, except rotation direction, the parameter such as pitch, flute profile of two kinds of screw threads is all identical, in the end of leading screw, has transition screw thread to be connected smoothly with right-hand screw thread by minus thread.Slide block is embedded in the screw thread of certain rotation direction, and slipper push strand oscillator moves.After slide block moves to the end of certain rotation direction screw thread, start to enter transition screw thread, slide block changes direction gradually by the compacting of transition screw thread, when slide block enter derotation to screw thread, namely complete the commutation of strand oscillator.

Detailed description of the invention
As depicted in figs. 1 and 2, axle head is used to support in one end of reel 15.Axle head supports can use independent bearing, bearing seat, also can utilize the bearing of reductor.What Fig. 1 showed is utilize the bearing of reductor 8 to support.The other end of reel uses two support rollers 12 being arranged in reel 15 side-lower to support.Center A, B of two support rollers and drum center O form equicrural triangle.Unless special requirement, the vertical central plane of two support rollers to reel is generally arranged symmetrically with.Wheel rim 2 is arranged on reel 15, and there is good cylindricity on surface, and its line of centers overlaps with spool spindle line of centers.Reel 15 can steadily rotate under the support of axle head-support roller.
At reel built with carbon brush 13, slip ring 14, completes the electrical connection of removal cable and the fixing electrical equipment that reel rotates by carbon brush-slip ring group.In one end that reel support roller supports, there is end cap 1.The obstruction supported owing to not having axle head, can unload bottom end cover 1 easily, carry out Inspection and maintenance to facility in reel.The end plate 6 of the reel other end, can be connected with spool body with bolt, also can electricity consumption is soldered connects.Removal cable 3 is wound on reel outside.
Cable winch shown in Fig. 1 adopts axle head to drive, and CD-ROM drive motor 7 drives spool spindle to drive reel by reductor 8.Reductor 8, except driving reel, also assume responsibility for the task of the axle head support of reel one end.At axle head drive pattern, support roller only bears the support of reel one end, does not bear other work.
Also can drive reel by driving support roller, in that driving mode, support roller 12 and wheel rim 2 process profile of tooth, intermeshes, support roller and wheel rim are actually gear, and CD-ROM drive motor is driven by reductor has tooth support roller to drive bull gear to drive reel.The cable winch structure that the cable winch of this type of drive and axle head drive is more or less the same.Drive the motor of support roller generally still to need to use reductor to slow down, but owing to there being the deceleration effort of tooth support roller and bull gear, reductor can be very little.
Cable winch configuration strand oscillator 4, strand oscillator 4 is also driven by reel driving system.In spool spindle, drive sprocket 9 is housed, and drive driven sprocket 11 to drive two-way leading screw 5 and reel synchronous rotary by chain 10, reel revolves and turns around, leading screw 5 drives strand oscillator 4 to move the distance of a cable size to suitable direction, and removal cable is reeled neatly on reel.
In order to solve the multilaminate coiled of cable winch, need solve the commutation problem of strand oscillator, strand oscillator leading screw adopts two-way leading screw for this reason.
Two-way leading screw as shown in Figure 2.On two-way leading screw, be carved with left-handed and dextrorotation two kinds of screw threads across, except rotation direction, the parameter such as pitch, flute profile of two kinds of screw threads is all identical.Slide block is embedded in the screw thread of certain rotation direction, and the slide block 23 in figure is embedded in minus thread 21, and slide block 23 promotes strand oscillator and moves, and in figure, strand oscillator does not draw.In the end of leading screw, transition screw thread 24 is had to be connected smoothly with right-hand screw thread 22 by minus thread 21.After slide block moves to the end of certain rotation direction screw thread, start to enter transition screw thread 24, slide block changes direction gradually by the compacting of transition screw thread.In figure, slide block 25 represents the position be in the middle of transition screw thread, and slide block is now in the most end of leading screw.When slide block enter derotation to screw thread, namely complete the commutation of strand oscillator.
