This old cable withdrawer is that harness consolidation, it is easy to tie up, is precisely weighed automatically, automatic material casting, and simple to operate by can Weighing type swing arm winding structure realize automatically bundled to be wound around waste and old cable.

The pivoted housing being arranged on body frame and the central shaft being inserted in pivoted housing can mainly be included by Weighing type swing arm winding structure, wherein pivoted housing bottom is uniformly equipped with multiple swing arms, so just constitutes a swing arm ring being surrounded by each swing arm in pivoted housing bottom.Swing arm upper end is hinged on below pivoted housing by horizontal hinge shaft, and such swing arm just can swing back and forth around hinge.In this patent, the axial line of horizontal hinge shaft and the tangent cooperation in horizontal hinge shaft place pivoted housing periphery, the swinging track place plane of therefore each swing arm is exactly the place plane of the corresponding pivoted housing warp of swing arm, namely swing arm swinging track place plane is in that explosion like is distributed centered on pivoted housing axial line.Describe for convenience, pivoted housing lateral direction is referred to as outer, pivoted housing axial line unwrapping wire is referred to as interior.In this patent, swing arm is in that middle part is protruded to pivoted housing direction of axis line on the whole, and swing arm two ends are to the shape gradually extending away from direction of axis line, namely swing arm curves inwardly in middle part the v shape of the outside rounding off in two ends.So, it is formed for a v shape cavity outside v shape swing arm, for convenience of narration, referred to as v shape groove.Because pivoted housing is to arrange according to axis vertical to install, therefore in naturalness, the swing arm in left side is in ">" shape, the swing arm on right side is in that "<" shape, the left and right sides cooperates, and just presents "> < " shape.Now just substantially form the toroidal cavity that a cross section is v shape outside swing arm ring, for convenience of narration, referred to as v shape ring chamber or v shape ring groove, and this v shape ring groove is just wound around, keeps in the position of cable.

Slide in pivoted housing and be fitted with central shaft, central shaft can only slide axially along pivoted housing inner chamber and can not pivoted housing relatively circumferentially rotate.Central shaft lower end is installed with conical blocks, and conical blocks pointed end is arranged.Conical blocks have two faces, and a face is the plane at top, and in-plane is affixed with central shaft lower end.Another face is the taper seat of bottom, and taper seat is evenly equipped with the one-to-one track with swing arm, and track is extended along taper seat straight up from conical blocks tip direction.Middle part of swing arm is installed with the extension block being extended towards track, and extension block end is provided with the counterpart with track cooperation, and counterpart can only slide up and down along track, and such central shaft and swing arm just constitute transmission matching relationship by extension block and track.When central shaft slides down to minimum point namely down stroke point relative to pivoted housing, along slide to track topmost, now, extension block is also up to the standard state counterpart.Because the outward-dipping lower end in track upper end slopes inwardly, so counterpart reaches outer stroke point or the up stroke point of its stroke, now swing arm is pushed outwardly to maximum rating, namely swing arm swing out to greatest extent or outer stroke point.Now swing arm ring top and bottom are correspondingly arranged up and down, and the opening direction of v shape ring groove horizontally outward, assumes "><" shape, for convenience of describing, this state are referred to as winding state or working condition.When central shaft moves up along pivoted housing from down stroke point, counterpart also drives extension block from track peak slide downward.Because the outward-dipping lower end in track upper end slopes inwardly, so counterpart can drive extension block to move inward, namely swing arm is driven inwardly to swing, now the opening direction of v shape ring groove also swings gradually downward with the swing of swing arm.When central shaft is moved upwards up to peak namely up stroke point along pivoted housing inwall, counterpart is along slide to track bottom.Because the outward-dipping lower end in track upper end slopes inwardly, so counterpart drives extension block to slide into inner terminal in inward-outward direction, namely the interior travel point of its stroke or down stroke point.Under extension block and counterpart pull, swing arm by conical blocks or track be drawn to inside swing to greatest extent namely interior travel point.Now, v shape groove cell wall lower half reaches vertical state, and v shape ring groove is in " ┐ ┌ " shape, for convenience of describing, this state is referred to as material casting state or idle state.

In this patent, body frame is fixedly mounted on the weighting platform of weighing apparatus, therefore can all items on symmetry bench be weighed in real time.Before non-wound wire, the weight of all items on weighting platform is almost invariable, namely on body frame and body frame, the weight of the structure member such as the pivoted housing of installation, central shaft, swing arm is all constant.Therefore, calculate the weight for convenience, all devices not being wound around on weighting platform and weighting platform before cable are referred to as total weighting platform, weight on weighing apparatus for total weighting platform is calculated as the zero point of range of weighing.So, after swing arm ring is wound around cable, the weight that weighing apparatus detects is the weight of the cable being wound around on swing arm ring, therefore, can know the weight of be wound around cable during being wound around cable simultaneously.When be wound around cable weight reaches predetermined weight, shut down at once, not only weigh conveniently, accurately, and simple to operate, and a people just can operate, and substantially increases organic efficiency.

The main power plant driving pivoted housing to rotate is provided with body frame, main power plant is by start stop apparatus control.So, when needing to reclaim waste and old cable, waste and old cable one end is previously wound around on swing arm ring, then manipulation start stop apparatus starts main power plant, main power plant just drives pivoted housing to rotate, now swing arm ring just starts to continue to be wound around cable.When the cable weight of weighing apparatus detection reaches requirement, manipulation start stop apparatus makes main power plant shut down, and operation is very simple.Knife rest corresponding with long cable section of ingoing line end is also equipped with base, knife rest is provided with the cutter sweep that cable is cut.The Main Function of cutter sweep is that cable is cut, that is, by cable cutting.After the cable that swing arm ring is wound around reaches and weighs and require and shut down, staff can manipulate cutter sweep by cable cutting, and the cable that such a bundle meets weight demands is just wound around and finishes.Then weighted cable circumference is tied by staff with auxiliary rope, at random to prevent, and so can be moved easily and deposit.Lowering or hoisting gear is also equipped with body frame, the Main Function of lowering or hoisting gear is to drive central shaft to move up and down.After cable weighs up to standard and cut-off, staff can manipulate lowering or hoisting gear and drive central shaft to rise.When central shaft reach up stroke point when, counterpart reach in travel point, now swing arm ring reach material casting state.After the cable tied loses the clamp position-limiting action of v shape ring groove, automatically drop on weighting platform under gravity, drag away, operation is very simple.So, a bundle meets the cable of the standard of weighing and just puts in order, repeat said process can continue to be wound around, weigh, harness cable, process is similar, is not described further in detail.

The spaced subframe 18 with body frame is also equipped with base，Secondary body frame 25 is installed with subframe，Subframe is provided with slide rail 26，The oriented pair pair that is slidably matched of body frame is installed on slide rail from frame 27，Secondary main shaft 19 is passed through on secondary body frame secondary driving gear 20 is installed，The secondary main half arc ring groove 21 being matched with cable is equipped with secondary driving gear periphery，Also include being arranged on secondary secondary driven gear 23 from frame by pair from axle 22，It is equipped with secondary driven gear periphery and match with cable and with the secondary corresponding pair of half arc ring groove of leading from half arc ring groove 24，Subframe and pair are provided with the auxiliary spring 28 making secondary driven gear mesh together with secondary driving gear elastic compression between frame，Secondary main half arc ring groove and pair are evenly equipped with burr 29 from the cell wall of half arc ring groove，The auxiliary-motor driving secondary driving gear to rotate is provided with secondary body frame，The linear velocity that secondary main half arc ring groove stirs cable is slightly faster than the linear velocity that pivoted housing is wound around cable.

Secondary body frame is fixedly mounted on subframe, and therefore both are the integrative-structure being fixedly connected.And pair is to be arranged on subframe by slide rail from frame, therefore pair can slide on subframe along slide rail from frame, therefore pair from frame and subframe be relative slip cooperating relationship.On subframe, slide rail is directed towards what secondary body frame was extended, and therefore when pair is slided along slide rail from frame, also just the secondary body frame of direction is mobile or deviates from secondary body frame movement from frame for pair.Secondary main shaft is provided with secondary body frame, secondary main shaft is provided with secondary driving gear, therefore secondary driving gear can rotate around its axial line.The auxiliary-motor driving secondary driving gear to rotate is also equipped with secondary body frame, therefore connects auxiliary-motor power supply and secondary driving gear can be driven to rotate.Pair is provided with pair from axle from frame, and pair is provided with secondary driven gear from axle, and secondary driven gear is engaged each other with secondary driving gear, and when so secondary driving gear rotates, secondary driven gear also can synchronous axial system.Subframe and pair are provided with spring between frame, and spring promotes pair to move to secondary body frame direction from frame, even if also secondary driven gear with secondary driving gear elastic compression and meshes together.Secondary main half arc ring groove is equipped with secondary driving gear periphery, the cross section of secondary main half arc ring groove is the semicircle matching with cable periphery.Pair is also equipped with secondary driven gear periphery from half arc ring groove, secondary is also the semicircle matching with cable periphery from the cross section of half arc ring groove, and secondary main half arc ring groove is correspondingly arranged from half arc ring groove with secondary.So, secondary main half arc ring groove and pair have just been buckled into a circular cavity corresponding with cable periphery from the convergence part of half arc ring groove, and this circular cavity is necessary channel before cable is wound around.Secondary main half arc ring groove and pair are evenly equipped with burr from the cell wall of half arc ring groove, the Main Function of burr is to increase secondary main half arc ring groove and pair from half arc ring groove frictional force or the clamping force with cable surface respectively, prevent skidding, the cable of distant place just can be pulled and deliver to body frame from half arc ring groove and enter cut cable by so secondary main half arc ring groove and pair smoothly, in time.In this patent, the linear velocity that secondary main half arc ring groove stirs cable is slightly faster than the linear velocity that pivoted housing is wound around cable, the purpose of so setting is that the pulling force pulling electric wire to be completed by the secondary driving gear on subframe and secondary driven gear completely, so swing arm ring be subject to when being wound around cable cable reversely to pull power just very little, it is negligible, substantially increase the precision that this patent is weighed to cable after being wound around.

Separator tube 30 is also equipped with base, separator tube is in meniscus shaped setting in the axial direction, separator tube is in diametrically the tapered circular tube shaped in the thicker two ends in middle part, buffering tube inlet is correspondingly arranged with subframe, and the outlet of separator tube is correspondingly arranged with the swing arm of body frame.

The Main Function of separator tube has three; one effect is because separator tube both ends open and middle closing; therefore transmission channels can be provided for the cable between body frame and subframe, there is protection cable reliability, the effect of smoothly transmission, the transmission of such cable would not be subject to ectocine.Because the linear velocity that secondary main half arc ring groove stirs cable is faster than the linear velocity that swing arm ring is wound around cable, the more and more excess cable failing to be wound around in time by swing arm ring that can produce therefore between body frame and subframe.Buffer tube design obtain two ends compared with detail between thicker meniscus shaped, its inner space is also that middle part is broad and gradually become narrow toward two ends, such that spatial design can be just that progressively longer excess cable provides abducent space.When just starting to be wound around, the excess cable between body frame and subframe is the shortest, and now honor cable is located at separator tube axial inwall the shortest, namely near at the axial inwall of body frame and subframe.It is being wound around cable mid-term, excess cable gets more and more, excess cable can bend outward expansion under elastic force at itself, namely moves at axial inwall the longest.It is being wound around the cable later stage, excess cable will extend in itself axial elasticity and continue outward expansion under tension force effect, and now excess cable will be adjacent on the longest axial inwall between body frame and subframe, namely on the farthest axial inwall of body frame and subframe.When continuing to be wound around cable, because separator tube is diametrically cylindrical, therefore increasing excess cable can be in buffering tube cavity mid-game circle under the effect of itself axial tensile force, and such separator tube just can be kept in more cables and will not have obvious traction force to swing arm ring.So, second effect of separator tube is to provide parking space for these excess cable.3rd effect of separator tube is to separate cable and people's physics, has fundamentally prevented the accident that cable is wound around human body, and the medicated clothing on the person, hair is involved in the risk of swing arm ring, substantially increases the safety of operator.

convenience of narration, this state is referred to as naturalness or upper state.When needing to cut cable, crane moves down under cutting lowering or hoisting gear drives.Because the height of briquetting is far below the height of cast-cutting saw slice, the cable that therefore briquetting will touch in cable trough prior to cast-cutting saw slice during naturalness.Because cable trough can only accommodate the latter half of cable, cable top half exceeds cable anvil upper surface, and therefore, when crane continues to decline, crane is by by being continued to press down on the cable in cable trough by pressing spring.Now press pressing spring compressive deformation, also increasing to the elastic force of briquetting by pressing spring.After the pressurized increase of cable, meeting gradually radial deformation, and fill up whole cable trough, effect cable being fixed on cable anvil so can be played, for cast-cutting saw slice, smoothly, reliably cutting cable provides guarantee, when fundamentally avoiding saw blade cutting cable, cable rotates the phenomenon rolling about or even rolling out cable trough under cast-cutting saw slice gets rid of dynamic action.After cable is fixed, cutting lowering or hoisting gear may proceed to drive crane to decline, and continues to compress and increase the pressing force to cable by pressing spring, and now cast-cutting saw slice starts to touch cable and start to cut cable.When cutting lowering or hoisting gear driving crane arrival down stroke point, pressing spring-compressed is the shortest, and briquetting reaches maximum to the pressing detent force of cable.For convenience of describing, this state is referred to as cut state or the next state.When the next state reset is to upper state, a cutting process just finishes.It is installed with, in briquetting below pressing slide bar, the pressing locating rod extending downwardly, cable anvil is provided with and presses the pressing location hole of locating rod upper and lower plug-in mounting cooperation.Before briquetting presses voltage cable, pressing locating rod can first insert pressing positioning in the hole, so can provide guide effect for the pressing of briquetting it is ensured that briquetting can vertically push it is ensured that pressing being smoothed out of positioning.Pressing locating rod lower end typically arranges thinner, accordingly even when there is plug-in mounting error, also can guarantee that pressing locating rod smoothly inserts pressing positioning in the hole.
