This multifunction power distribution line stringing assistor mainly includes the base, support cylinder and upper bracket set gradually from bottom to top, its support tin and base are to be hinged matching relationship, matching relationship is namely swung, upper bracket and support cylinder are also to be hinged matching relationship, namely swing matching relationship.Specifically, base top is installed with support, and support is by support shaft together with support cylinder lower hinge.In this patent, because support shaft is horizontally disposed, therefore support cylinder can swing back and forth around support shaft in corresponding vertical plane.For convenience of describing, cylinder will be supportted and be referred to as hinged end or lower end with one end that support is hinged, the support cylinder other end is referred to as swinging end or upper end.In this patent, support cylinder is a hollow rectangle pipe, therefore not only quality is slim and graceful, easy to carry, and with stronger structural strength, it is ensured that the reliability in use.A lower gear is installed with a side wall for supportting cylinder, lower gear is coaxially disposed with support shaft, the lower gear also synchronous hunting so when supportting cylinder and being swung around support shaft, conversely, support cylinder is also just fixed when lower gear is positioned motionless.Support is provided with lower positioner corresponding with lower gear, can make the tooth clamp location fit of lower positioner and lower gear by the lower positioner of operation, such lower gear is just positioned by lower positioner.For convenience of describing, lower gear is referred to as lower positioning states by the state that lower positioner is positioned.In lower positioning states, lower gear is that fixing card load connects matching relationship with support, now, and lower gear is unable to opposite brackets swing, namely support cylinder and integrative-structure of the base for locking.Because lower positioner is the tooth clamp location fit with lower gear, thus instantly positioner different from lower gear tooth clamp location fit when, lower gear is at different swing angles.That is, in hunting range, support cylinder swings to unspecified angle, and lower positioner can lock lower gear, support cylinder is set to be fixed on base.Obviously, when support cylinder be in vertical state when, support cylinder swinging end respect thereto apart from highest, and when support cylinder swing to close to horizontality when, support cylinder swinging end respect thereto distance it is minimum.Because base is installed in pole arm by lower locking device, and support cylinder swinging end is the support zone of unwrapping wire cable 00, therefore, supportting the height highest that unwrapping wire cable is propped up when cylinder vertical state is locked, the height that unwrapping wire cable is propped up when supportting cylinder horizontality is minimum, and the height that unwrapping wire cable is propped up when supportting cylinder positioned between vertical state and horizontality is directly proportional to supportting the height of cylinder swinging end.So, in unwrapping wire, only need to be last to pole arm by floor installation, the height that unwrapping wire cable is propped up can be controlled by adjusting the angle of inclination of support cylinder, base fixed position need not be changed, it is not required that greatly apart from lift to move unwrapping wire cable, a people is operable, it is time saving and energy saving, it is favorably improved unwrapping wire efficiency.
Support cylinder upper end is installed with two main supporting plates upwardly extended and sub-strut plate, and main supporting plate and sub-strut plate are located on two opposite faces of support cylinder and concordant with supportting the respective side wall of cylinder set respectively.Main supporting plate and sub-strut plate be arranged in parallel, form a cavity between the two, the cavity is the passage that unwrapping wire cable passes through.A main axle is vertically installed between main supporting plate and sub-strut plate, main axle be arranged in parallel with support shaft.Main wheel is set with main axle, main wheel can freely be rotated around the axial line of main axle.When carrying out unwrapping wire, unwrapping wire cable realizes axial movement under the rolling support of main wheel.Therefore, in actual payoff operation, it is necessary to adjust support cylinder inclined degree when, the foundation of reference be exactly on the main wheel wheel hub for make support unwrapping wire cable the height of avris it is consistent with the insulator top line groove height of unwrapping wire cable to be placed.Because main wheel can be rotated freely, therefore unwrapping wire cable can be very smooth when being pulled and moving axially, not only rapid operation, and protect unwrapping wire cable.In this patent, the hub periphery face for the main wheel being in contact with unwrapping wire cable be set to middle part to main axle is close and edge is gradually distance from the cambered surface of main axle, namely main wheel is that mid diameter is most thin, more toward the thicker structure of two ends main wheel diameter, the hub periphery part of such main wheel and unwrapping wire conductive cable contacts is exactly the groove structure of a rounding off.The purpose so set is radially spacing to unwrapping wire cable on the move progress, unwrapping wire cable is set to be constantly under gravity near the bottom land of above-mentioned groove structure, it so can not only avoid unwrapping wire cable on the move from running off groove structure and come off, it also avoid scratching unwrapping wire cable sheath because the main supporting plate and sub-strut plate of both sides is touched.
In this patent, upper bracket is provided with above support cylinder, is to be provided with upper bracket above main supporting plate and sub-strut plate precisely.For convenience of describing, the structure that main supporting plate and sub-strut plate are constituted is referred to as double plate structure, and upper bracket buckles cover cooperation with double plate structure, and the state that both correspondence button covers coordinate is referred to as into buckling state.In buckling state, upper bracket and double plate structure just define a relatively closed O-shaped structure, the O-shaped structure is exactly the activity space structure of unwrapping wire cable, therefore upper bracket has spacing unwrapping wire cable activity scope, the effect for preventing unwrapping wire cable from being slipped during unwrapping wire.In this patent, double plate structure avris is provided with gear by rotary connecting device, and double plate structure side wall is rotated where gear can be adjacent to by rotary connecting device.Gear top is hinged cooperation by trunnion axis and upper bracket respective side, and trunnion axis is vertically arranged with gear axial line, therefore upper bracket can be swung around trunnion axis with respect to gear.In summary, when gear is swung, upper bracket is also inevitable is swung therewith, and in buckling state, upper bracket can be interlocked from the different parts of double plate structure with different angles.The purpose so set, it is exactly in lower positioning states, upper bracket can be made to be in the surface of main axle all the time, even if also above-mentioned O-shaped structure is in erectility, now above-mentioned O-shaped structure is maximum to effective scope of activities that unwrapping wire cable is provided, both it can guarantee that unwrapping wire cable will not be slipped, and can make unwrapping wire cable is free, smooth in maximum range of activities to slide again, it is ensured that the reliable, smooth of this patent is used.
In this patent, positioner, the tooth clamp location fit that upper positioner can be with gear, so as to play the positioning action to whole gear are installed on support cylinder.For convenience of describing, the state that gear is positioned is called into upper positioning states by upper positioner.In upper positioning states, gear is integrally formed formula fixed structure with double plate structure, and gear is integrally formed formula fixed structure with support cylinder top in other words.Because upper positioner is the tooth clamp location fit with gear, therefore when upper positioner tooth clamp location fit different from gear, gear is just different from the relative position relation of double plate structure or support cylinder, and it is most significantly exactly that the upper bracket being hinged on gear is different from the relative position relation of double plate structure or support cylinder to characterize.That is, pass through the upper positioner of the operation tooth clamp location fit different from gear, the fixed position relative of upper bracket and support cylinder can be adjusted or angle is relatively fixed, so also it can be achieved with lower positioning states, upper bracket can be kept to be in erectility or vertical state, it is more smooth and reliable when making unwrapping wire cable drum so that foregoing O-shaped structure reaches optimum Working.
In this patent, upper locking device is provided between sub-strut plate and upper bracket, the main function of upper locking device is that the corresponding portion correspondence for making upper bracket and sub-strut plate is locked together, so foregoing O-shaped structure just constitutes the O-shaped structure that a structure is fixed, even if unwrapping wire cable is rocked up and down in O-shaped structure internal cause external force, also it will not be slipped out of O-shaped structure, it is ensured that the reliability and smoothness of payoff operation.For convenience of describing, the state of upper bracket locking corresponding with sub-strut plate is referred to as upper locking state.When unwrapping wire cable, axially drawing is rear in place, it is necessary to when unwrapping wire cable is fixed at the top of insulator, need to only unlock upper locking device, you can make upper bracket separation above double plate structure, upper bracket also is put away into double plate structure around trunnion axis.Now, above-mentioned O-shaped structure divide into the U-shaped structure of two separation, easily can take out unwrapping wire cable.Since cylinder upper end is supportted, namely the main wheel in double plate structure has been adjusted to the position contour with insulator wire casing, therefore unwrapping wire cable only need to be substantially translated, it is simple to operate, it is time saving and energy saving.
In this patent, an accessory whorl axle is installed, accessory whorl axle be arranged in parallel with main axle in upper locking state on upper bracket.Accessory whorl is installed, accessory whorl can freely be rotated around the axial line of accessory whorl axle on accessory whorl axle.In this way, can be when unwrapping wire cable is touched accessory whorl by external force, accessory whorl can be rotated with unwrapping wire cable synchronizing, effectively prevent friction.The hub periphery face of accessory whorl be middle part to accessory whorl axle is close and cambered surface of the edge away from accessory whorl axle.In upper locking state, upper bracket and double plate structure constitute O-shaped structure, under the support of O-shaped structure, main wheel and accessory whorl are buckled into the oblong cavity that can freely a rotate structure, and the space that the oblong cavity structure is limited is exactly the actual activity space of unwrapping wire cable.Because the activity space is oval, therefore no matter unwrapping wire cable by how the external force in direction, the contact with oblong cavity structure of unwrapping wire cable is all that rounding off coordinates, and both contacts are synchronization-moving, therefore the frictionally damage that unwrapping wire cable crust during unwrapping wire is subject to has been inherently eliminated it.
In the present embodiment, lower locking device mainly include parallel interval is set up and down upper flat plate with lower flat board, be fixedly connected with the stringer board of upper flat plate and lower flat board, and the bolt being screwed onto on lower flat board.Traditional cross-arm has two vertical fixed platen surfaces, for convenience of describing, horizontally disposed flat board is referred to as into level board, another vertically disposed flat board is referred to as into vertical panel, an avris of level board is corresponding with the upper avris of vertical panel to be fixed together.In this patent, upper flat plate and lower flat board are spaced up and down, therefore form a clip slot or cavity between the two.The width of the clip slot is wider than the level board of cross-arm, in order to which the level board of cross-arm is smoothly inserted into clip slot.For convenience of describing, one end that cross-arm level board is inserted in clip slot is referred to as the inner, and by the other end, namely with vertical panel, affixed one end is referred to as outer end.Lower flat board is provided with screw, and screw is axially vertically disposed, and bolt is bolted with screw.When in cross-arm level board the inner inserting to clip slot, the level board of cross-arm can be fixed to clamp in clip slot by way of the screwed in place bolt into clip slot, so as to realize the fixation of cross-arm level board and upper flat plate and lower flat board, being fixedly connected for card holders and cross-arm is so also achieved that, the fixed installation to pole tag is also achieved that.
In the present embodiment, the lower positioner includes the glide path 19 being arranged on support, slided in glide path and be fitted with drop shot 20, drop shot includes the lower built-in section 21 being fixed together and lower extension section 22, lower built-in section is resiliently connected together by tension spring 23 and glide path end, the lower corner block 25 that axially inserting coordinates of lower teeth groove 24 with lower gear is installed with lower extension section, glide path is provided with the lower cone groove 0026 being slidably matched with lower corner block, lower corner block is installed with the lower pyrometric cone block 26 of arris and lower corner block rounding off close to one end of lower built-in section, lower extension section and lower corner block end are installed with lower draw ring 27.This lower positioner is positioned by sliding the spacing fit structure of clamp to realize to lower gear.Sliding the spacing fit structure of clamp mainly includes the glide path being arranged on support and the drop shot being inserted into glide path, wherein, glide path extends laterally setting, and drop shot can slide laterally in glide path.In this patent, glide path includes two-part structure, that is, extends laterally the glide path main body and lower cone groove of setting.The quantity of lower cone groove is one, is arranged on glide path one end corresponding with lower gear and is set close to lower gear.Lower cone groove is the translot structure that a vertical cross section extended laterally is triangle, therefore looked up from perpendicular that lower cone groove is exactly the wide pyramidal structure in the sharp lower end in a upper end.The positions and dimensions of lower cone groove can make lower gear namely lower teeth groove laterally perfectly aligned with lower cone groove when turning to lower cone groove correspondence position.Lower cone groove and glide path be above and below matching relationship.Both connections are a larger trough body structure.For convenience of describing, the trough body structure is turned into vat.Corresponding with vat, drop shot also includes two-part structure, i.e., lower built-in section and lower extension, and lower built-in section and lower extension all slide laterally cooperation with glide path.Lower built-in section is arranged far from glide path one end of lower gear, and pass through tension spring and glide path corresponding end elastic connection, so when not acted on by other external force, drop shot can be pulled down spring elasticity and pull to glide path away from lower gear one end, serve the effect of automatic tension drop shot.Lower extension section is correspondingly arranged with lower gear, positioned at lower extension section lower section.A lower pyrometric cone block and a lower corner block are installed with lower extension section, pyrometric cone block and lower corner block are located at lower extension section on the side wall of lower gear.Lower corner block is the prism that the vertical cross-section extended laterally is triangle, lower corner block has two end faces and three sides, one of side is corresponding affixed with lower extension section top surface downwards, and remaining two sides convergence part, which constitutes a straight seamed edge extended laterally and is adjacent to lower cone groove, slides laterally cooperation.In this patent, lower pyrometric cone block is located at lower corner block close to one end of tension spring, and lower pyrometric cone block is that a cross section is subtriangular circular cone.Lower pyrometric cone block has one back to the bottom surface of tip and three sides, bottom surface is corresponding with small corner block affixed, one of side is corresponding affixed with lower extension section top surface downwards, remaining two sides are that, from tip to the cambered surface of bottom surface rounding off, and two cambered surface convergence parts constitute the bended edge from lower extension section top surface to foregoing straight seamed edge rounding off.The main purpose for setting pyrometric cone block is, in order to correct the degree of registration of the lower teeth groove of lower gear and lower cone groove, enable both perfectly aligned, thus to serve the guide effect for making lower corner block accurately slip into lower teeth groove along lower cone groove.In positioning, tension spring can pull lower pyrometric cone block and lower corner block to bore groove and the slip of lower teeth groove downwards by drop shot.Because lower pyrometric cone block have tip, therefore slip into it is much smoother, with guide effect.If the position of lower gear is improper to prevent lower teeth groove and lower cone groove from aliging, the tip of lower pyrometric cone block and bended edge can gradually slip into lower teeth groove, and apply pressure to stir lower gear rotation to lower gear using its side during slipping into, finally make lower teeth groove and lower cone groove perfectly aligned, therefore this patent has the function of automatic aligning, centering.Lower pyrometric cone block can preferentially slip into lower teeth groove after tooth slot position under correction, and corner block is also corresponded to and slipped into lower teeth groove under being pulled under tension spring effect.Because two side walls of lower corner block and two side walls of lower teeth groove are adjacent to and are slidably matched, therefore lower corner block is slipped into after lower teeth groove, and gap is not present between lower teeth groove and lower corner block.For convenience of describing, this state is referred to as lower insert state or lower positioning states.Because lower corner block can only slide axially along lower gear, and lower gear can only be rotated around its axial line, therefore lower gear can not be rotated in lower insert state, namely be positioned.In this patent, lower extension section and lower corner block end are installed with lower draw ring, when needing to release positioning,
