This distribution cable retracting device 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, swing arm end is corresponding with central shaft hinged by brace, so just constitutes a swing arm annulus being surrounded by each swing arm and brace 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.For convenience of describing, pivoted housing lateral direction is referred to as outer, namely referred to as outer from central shaft side farther out, pivoted housing direction of axis line is referred to as interior.In this patent, pivoted housing outer wall is in the thick cone in the thin upper end in lower end, and swing arm is hinged on turntable lower end, and therefore, when the swing position of swing arm is different, swing arm is also just different from the circumferential profile of pivoted housing.When swing arm lower end swings out, swing arm lower end is more remote apart from pivoted housing cental axial position than upper end, and now, each swing arm constitutes the v shape groove of a traverse with corresponding pivoted housing outer wall, namely constitutes a v shape cavity.Because pivoted housing is that the therefore v shape cell wall in left side is in ">according to the setting of axis vertical direction " shape, the v shape cell wall on right side is in that "<" shape, the left and right sides cooperates, and just assumes "><" shape.So, the cone shaped outer wall of swing arm annulus periphery and pivoted housing is the formation of the toroidal cavity that a cross section is traverse v shape, for convenience of describing, this toroidal cavity is 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.The swing arm annulus of v shape ring groove and the assembly of pivoted housing outer wall will be supported to be referred to as swing arm ring, pivoted housing outer wall is referred to as the upper wall of swing arm ring, the outer wall of pendulum annulus track is referred to as lower wall.

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 upward sliding has individual extreme position it is simply that up stroke point, slide downward also has individual extreme position it is simply that down stroke point.When central shaft is relative to pivoted housing upward sliding to peak namely up stroke point, brace is up to the standard state, and now central shaft and brace is vertically arranged.Now, swing arm lower end is supportted with a distance from central shaft farthest by brace, and swing arm ring upper wall and lower wall are almost symmetrical arranged, and the opening direction of v shape ring groove horizontally outward, assumes "><" shape, for convenience of describing, this state is referred to as winding state or working condition.When central shaft moves down along pivoted housing from up stroke point, brace drives swing arm lower end to move gradually downward, and now distance center wheelbase in swing arm lower end is close to increasingly.When central shaft is moved down into minimum point namely down stroke point along pivoted housing inwall, brace lower end moves down into lowest part, namely the position near central shaft, and brace upper end also reaches distance center axle proximal most position.Now, swing arm lower end is located at outside swing arm upper end and brace lower end connecting line, the purpose of so setting is when central shaft slides again up, central shaft can easily pass through brace and drive swing arm outwards to prop up, when fundamentally avoiding swing arm lower end and being located at swing arm upper end and brace lower end connecting line or be located inside swing arm upper end and brace lower end connecting line, central shaft is subject to brace and swing arm can not outwards strut bending and cause cannot go up shifting problem.Now, v shape groove cell wall lower half reaches almost 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 reaches up stroke point, swing arm ring reaches 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.

In the present embodiment, described lowering or hoisting gear includes the overcoat 34 being installed on body frame, being fitted with overcoat can only be along the inner sleeve 35 of outer casing inner wall axial sliding fit, inner sleeve inner chamber bottom is assembled with central axle sleeve and is closed and can only be rotatably assorted, inner sleeve upper inside wall is provided with main internal thread segment 36, also include the power transmission shaft 37 being rotatably installed on body frame, power transmission shaft hypomere is the main external thread section 38 with main internal thread segment threaded, travelling gear 39 is provided with power transmission shaft, also include the lifting motor 40 being arranged on body frame, the lifter wheel 41 being engaged with travelling gear is provided with the output shaft of lifting motor.

This lowering or hoisting gear is electrically driven (operated) lowering or hoisting gear, provides power by lifting motor.Lifter wheel is provided with the output shaft of lifting motor, lifter wheel is engaged with travelling gear, travelling gear be fixedly mounted on can only axial rotation and on the power transmission shaft that can not move axially, therefore lifting motor will drive power transmission shaft synchronous axial system when rotating.Power transmission shaft bottom is connected with inner sleeve upper transmission, and inner sleeve bottom is connected with central shaft upper transmission.Inner sleeve is the core component of this lowering or hoisting gear, and the rotatory force of power transmission shaft is converted into the lifting force of central shaft by inner sleeve.Inner sleeve is slided and is inserted in overcoat, and overcoat is fixedly mounted on body frame, and therefore inner sleeve can only axially slide up and down relative to overcoat and can not rotate relative to overcoat.Inner sleeve upper inside wall is provided with main internal thread segment, and power transmission shaft bottom is provided with main external thread section, main external thread section and main internal thread segment threaded.Therefore, when the drive axis that can only circumferentially rotate, power transmission shaft will drive the inner sleeve that can only move axially to move up and down.Because inner sleeve inner chamber bottom and central axle sleeve assembling is closed and both can not move to axial, therefore interior be enclosed within power transmission shaft drives when moving up and down, central shaft is also inevitable to be lifted therewith.Therefore, as long as controlling the rotating of lifting motor with regard to the lifting of power transmission shaft and inner sleeve control centre axle can be passed through, very simply.Inner sleeve bottom and central shaft top can only be circumferentially rotated the purpose of cooperation, be to adapt to when being wound around cable central shaft with the needs of swing arm ring synchronous axial system.

Described cutter sweep includes being spaced two cable anvils 50 being installed on knife rest 16，Cable anvil is provided with the cable trough 51 being slidably matched with cable the latter half level，The crane 55 being driven lifting by cutting lowering or hoisting gear 54 is provided with knife rest，Crane bottom is two parallel support arms 56 extending downwardly，The cutting motor 66 that the support arm shaft 57 that support arm lower end passes through to rotate is fixed with cast-cutting saw slice 58 and drives support arm shaft to rotate，The pressing sliding sleeve 67 being vertically arranged is fixedly provided with support arm，Slide in pressing sliding sleeve and be fitted with pressing slide bar 68，Pressing slide bar lower end is installed with cable anvil up and down by the briquetting 69 of press-fit，It is installed with, in briquetting below pressing slide bar, the pressing locating rod 70 extending downwardly，Cable anvil is provided with and presses the pressing location hole 71 of locating rod upper and lower plug-in mounting cooperation，Pressing slide bar upper end is installed with pressing limited block 72，Pressing slide bar between pressing sliding sleeve and briquetting is provided with by pressing spring 73.

In this cutter sweep, cable anvil, crane and cutting lowering or hoisting gear are core textures, and cable anvil and cast-cutting saw slice are the critical pieces completing to cut cable.Cable anvil is fixedly mounted at knife rest bottom, and therefore both are affixed integrative-structures.Cable anvil top is provided with the cable trough being slidably matched with cable, and when swing arm ring is wound to cable, cable first slips over cable trough, is then just wound on swing arm ring.Crane is arranged on the knife rest above cable anvil, and crane completes lifting action by cutting lowering or hoisting gear and drive.Crane bottom is two support arms being correspondingly arranged up and down one by one with two cable anvils, and support arm lower end is provided with cast-cutting saw slice by the support arm shaft rotating, and is provided with the cutting motor driving support arm shaft to rotate outside support arm.So, when cutting motor obtains electric, will pass through support arm shaft and drive cast-cutting saw slice high-speed rotation.When cutting lowering or hoisting gear driving crane decline, just the cable between two cable troughs cuts the cast-cutting saw slice of high-speed rotation, thus completing to cut off the work of cable.It is installed with a pressing sliding sleeve being vertically arranged on rear side of two support arms

upwards from pressing sliding sleeve it is also possible to play.Because briquetting and cable anvil correspond setting up and down, therefore, when crane moves down, briquetting also has the effect of pressing cable trough inner cable.It is set with pressing slide bar between pressing sliding sleeve and briquetting by pressing spring, press spring upper end elastic compression in pressing sliding sleeve lower surface, pressing lower spring end elastic compression is in briquetting upper surface.Therefore under self gravitation and pressing spring force effect, when not being subject to the effect of other external force, pressing slide bar relatively presses sliding sleeve and slides down to maximum position, now pressing limited block and the pressing spacing cooperation in sliding sleeve upper surface.Now, pressing slide bar downwards skid off pressing sliding sleeve length the longest, the distance that briquetting drops to below cast-cutting saw slice is also farthest.For 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.
