This electric stringing cross-line device is can quickly to be assembled or frame by adjustable clamp compact form rolling supporting structure to realize It is easy to operate, without ascending a height if cross-line, take-up, lead function can be completed on ground, it is safe.
Adjustable clamp compact form rolling supporting structure includes mainly the pedestal supported by insulating bar and is hinged on upper on pedestal Lid, upper cover can be rotated around hinged shaft to realize the function of being fastened on pedestal or raised from pedestal.Pedestal is equipped with bottom tub, Bottom tub horizontal extension simultaneously penetrates through pedestal both ends, bottom tub be mainly across cable offer pass through space.For convenience of narration, In horizontal plane, before and after the direction of both ends that bottom tub is penetrated through is referred to as, connection direction is known as longitudinal, bottom tub both sides Direction be referred to as left and right, the direction of connection is known as laterally, and the direction of vertical level is known as vertical or Vertical Square To.Return pulley is installed, the axial line of return pulley shaft is laterally arranged in bottom tub.Idler wheel will play the passed through cable of rolling support Effect, reduces the integrality that cable skin is improved across smoothness and ensure that across frictional force.Also is provided on upper lid with The corresponding upper cover slot of bottom tub, upper cover slot also penetrate through the setting of upper cover both ends.When upper cover fastens on pedestal, upper cover slot and pedestal Slot will be vertically connected with integrally.Upper cover slot and bottom tub are vertically connected with integral cavity for convenience of narration or through slot is known as " conveying trough " or " full slot ", is known as buckling state or closed state by the state that upper cover and pedestal snap together, by upper cover from The state raised on pedestal is known as the state of raising or open state.Auxiliary wheel is provided in upper cover slot, auxiliary wheel is filled by adjusting It sets and is installed on the upper cover.The rotating shaft core line of auxiliary wheel is also that left and right is extended or is laterally arranged, in this way, in buckling state When, auxiliary wheel shaft and return pulley shaft are arranged in parallel.Because return pulley and auxiliary wheel periphery are equipped with the annular groove coordinated with cable, institute With, as soon as similar circular gap or a cavity, the gap or cavity will be formed between auxiliary wheel and return pulley in buckling state When being transmission cable cable by cavity.For convenience of narration, which is known as " transmission cavity " or " cable chamber ".Regulating device Main function, be that the depth position to auxiliary wheel in upper cover slot is adjusted, when exactly adjusting buckling state auxiliary wheel and The spacing of return pulley, that is, adjust the size or thickness of transmission cavity.When transmission cavity is thicker than upper cross-line cable, cable and return pulley, The rolling cooperation of auxiliary wheel makes cable smooth transmission in transmission cavity.For convenience of narration, by this cooperation of auxiliary wheel and return pulley State is known as " transmission state " or " smooth state ".
In this electric stringing cross-line device, supporting rod is fixedly provided on pedestal, supporting rod connects between upper cover and pedestal Connect the lower section of hinged shaft.Supporting rod end is hinged with a drive link, and drive link upper end is hinged with upper connecting rod, upper connecting rod upper end and hinge Upper boom part above axis corresponds to hinged.Because hingedly coordinating each hinged shaft generally all in upper connecting rod and drive link institute It is that hinged shaft between upper cover and pedestal is disposed in parallel, rather than vertically disposed, therefore when swinging up and down drive link lower end When, drive link upper end also can drive upper connecting rod lower end to swing up and down, and because supporting rod and hinged shaft be relatively fixed it is motionless, because Swinging up and down for this upper connecting rod lower end can only drive upper cover to swing around hinged shaft by upper connecting rod upper end, also be achieved that in this way It drives the fastening of upper cover or opens wide.Sliding sleeve is equipped with upper sliding sleeve on drive link hypomere, and vertical downwards extend is hinged on upper sliding sleeve Insulating bar, the middle sliding sleeve of sliding suit insulating bar is installed on insulating bar, in this way in sliding sleeve just by the action of insulating bar restriction For that can only slide up and down.Insulating bar lower end is provided with operating parts, can easily be driven on insulating bar by moving operation part Lower movement, at this time the upper sliding sleeve of insulating bar upper end the power of insulating bar slided up and down can be divided into driving drive link hypomere on move down Dynamic power and make the power that upper sliding sleeve is slided up and down along drive link, can thus be driven by the transmission of drive link and upper connecting rod Lid is completed to fasten or open wide action.Specifically, when driving insulating bar to move up by operating parts on the ground, on insulating bar Driving drive link lower end is moved up and drive link upper end is made to move down by end, at this time drive link upper end will by upper connecting rod by upper cover the bottom of from Pull-up on seat, also just complete on the ground control insulating bar above upper cover open wide or action of uncapping.Conversely, when passing through operation When part driving insulating bar moves down, supporting rod will drive upper cover to fasten on pedestal by upper connecting rod, also just complete on the ground Control the upper cover fastening above insulating bar or buckle closure action.For convenience of narration, the upper cover above insulating bar will be controlled on the ground It is uncapped or all transmission mechanisms of buckle closure action is known as Yuan Kong mechanisms.
When Yuan Kong mechanisms and regulating device coordinate, three kinds of functions can be realized:Fixed clamp lives in cross-line end The lower cross-line cable other side is crossed from lower cross-line cable side(Cross-line or more line), fixed clamp live in cross-line end and to Preceding guiding pulls cross-line cable(Lead), upper cross-line cable chosen it is high to above lower cross-line and keeping suitable with upper cross-line cable That freely, stablizes lifts relationship(Take-up).
By operating regulating device, the thickness of transmission cavity can be controlled.When transmission cavity is thicker than upper cross-line cable, cable with The rolling cooperation of return pulley, auxiliary wheel makes cable smooth transmission in transmission cavity.Specifically, when needing cable suitable in transmission cavity When smooth transmission, upper cover and pedestal are switched to buckling state, are adjusted up auxiliary wheel by regulating device, that is, to upper cover Slot slot bottom direction is adjusted, and transmission cavity cross section becomes larger at this time, thicker than institute transmission cable.When cable is when cable intracavitary transmits, By cable gravity, generally only return pulley can carry out rolling support and limit by its annular groove to cable lower part and lower part both sides Position, only when cable shakes and is detached from return pulley upwards, auxiliary wheel just can by its annular groove to cable top and top both sides into Row rolling support and limit, therefore cable surrounding can relatively be had rolling support and the rolling of " elasticity " by auxiliary wheel and return pulley Position-limiting action, scope of activities of the cable in transmission cavity is bigger, such cable can the smooth movement in transmission cavity, may be used also With by pedestal and upper cover freely raise or reduce transmission cavity inner cable and do not interfere with cable transmission speed and epidermis it is complete Property.Transmission state is suitble to the rolling support when upper cross-line cable has been inserted across lower cross-line and upper cross-line in transmission cavity Cable quickly transmits use.For convenience of narration, this mated condition of auxiliary wheel and return pulley is known as " transmission state " or " smooth State ".
When transmission cavity is thinner than upper cross-line cable, under the driving of Yuan Kong mechanisms, upper cover is pressed on pedestal, auxiliary wheel and Return pulley handles upper cross-line cable clip, and upper cross-line cable is relatively fixed in transmission cavity at this time.Specifically, regulating device is operated Auxiliary wheel under buckling state is moved down, that is, auxiliary wheel is lifted from upper cover slot slot bottom, at this time auxiliary wheel and return pulley Spacing reduces, and transmission cavity becomes thinner than wanting transmission cable namely to go up cross-line cable.In this way, under buckling state, auxiliary wheel With return pulley " chucking power " up and down will be generated to upper cross-line cable and by upper cross-line cable clamping transmission cavity, upper cross-line cable and bottom Seat, upper boom be relatively fixed together, at this time can by insulating bar by the upper cross-line end clamped by lower cross-line side across More arrive the other side.For convenience of narration, this mated condition of this auxiliary wheel and return pulley is known as " clamp position " or " clamps shape State ".
When stringing needs cross-line, two sets of this electric stringing cross-line device cooperatings are generally required.The first step covers two sets Electric stringing cross-line device is all adjusted to clamped condition, then operate first set electric stringing cross-line device Yuan Kong mechanisms make its clamp on Cross-line cable front, it is then upper to lift insulating bar by upper cross-line cable front by lower cross-line cable side(Rear)Cross lower cross-line The cable other side(Front), thereby realize cross-line or more line.Second step operates the remote control of second set of electric stringing cross-line device Mechanism clamps the upper cross-line cable front crossed in front of lower cross-line cable(It is equivalent to and completes lead function).Third step will First set electric stringing cross-line device is removed from upper cross-line cable and operating regulating device makes it be switched to transmission state, finally will Lid and bottom cover for seat is attached on cross-line cable thereon, and this completes the smooth take-ups to upper cross-line cable.In first set electricity The take-up of power stringing cross-line device is lifted under effect, can be by upper cross-line when lifting second set of electric stringing cross-line device forward movement Cable is from lower cross-line side(Rear)Much constantly to the other side(Front)Cross-line or more line.
As a kind of realization method, the regulating device includes frame, and frame includes two vertical poles disposed in parallel and sets The Inter cross bar in vertical pole corresponding end is set, cross bar both ends are linked together by horizontal axis and vertical pole, and cross bar is rotated around horizontal axis, auxiliary Wheel is corresponding to be mounted between two vertical poles, further includes the screw hole penetrated through inside and outside upper cover and the screw rod coordinated with screw hole, screw rod upper surface It is equipped with driver slot, screw rod lower end is coaxially installed with extension rod, and extension rod lower end is coaxially installed with the diameter circle bigger than extension rod Disk, cross bar middle part are equipped with the horizontal chamber coordinated with extension rod, disk rotational.
Because frame includes two vertical poles being formed by connecting by horizontal axis and two cross bars, and auxiliary wheel be mounted on two vertical poles it Between, so when frame lifts, auxiliary wheel is also inevitable to be lifted therewith.Horizontal chamber is equipped in the middle part of cross bar, horizontal intracavitary is loaded under screw rod The extension rod and disk at end.Because screw rod, extension rod and disk are all coaxial arrangements, and the diameter of disk is more than extension rod Diameter, so screw rod can only be rotated by extension rod and disk opposing rail around screw rod axial line, and cannot be along screw rod axial line It slides up and down.Upper lid is equipped with two screw holes, two screw rods at frame both ends threaded corresponding with two screw holes respectively, institute With when screw rod precession corresponds in screw hole, frame will be lifted on by two screw rods in the upper cover slot of upper cover.Screw rod outer end is equipped with Driver slot, when pushing driver slot to rotate from upper outer side of lid, screw rod will be with respect to screw hole precession or back-out.At this time since frame cannot Rotated together with screw rod, so frame can only axially along a screw move under the drive of disk and extension rod, that is, deeply on Cover slot slot bottom or separate upper cover slot slot bottom, are also achieved that the lifting of auxiliary wheel.Because cross bar is hingedly matched by horizontal axis with the longitudinal axis It closes, therefore in turn screw rod, two screw rods can be asynchronous, i.e. first lifting frame one end lifting frame other end again, avoids Inconvenient property when synchronous turn screw rod.
As an improvement, be installed with sliding block on the outside of vertical pole, the length direction of sliding block and the length direction of vertical pole be vertically arranged and It is arranged in an axially parallel mode with screw rod, upper cover groove groove wall is equipped with the sliding slot being slidably matched corresponding with sliding block.
Sliding block, and the sliding slot that setting is slidably matched with sliding block in upper cover groove sidewall are set on the outside of vertical pole, can be played Front-rear direction relative limit effect is carried out when being lifted to frame, and when frame to be installed in upper cover slot, can also be played Guiding function.Because the length direction of sliding block is arranged in an axially parallel mode with screw rod, therefore sliding block and being slidably matched for sliding slot can protect The driving lower frame demonstrate,proved in screw rod can only do stable elevating movement.
As a further improvement, upper cover outer wall is equipped with the calibration loop of ring screw hole setting, the screw rod outer end of driver slot one end Face is equipped with standard, and calibration loop zero is directed toward in driver slot one end that standard is close when screw rod outer end face is concordant with upper cover outer wall Point.
Screw rod rotates a circle, and screw rod feeds a screw pitch in the axial direction.If screw rod rotation is not whole one week, very Difficult accurate judgement screw rod axial feed is how many.So the calibration loop that ring screw hole is arranged is arranged on upper cover outer wall can play finger The consistency of two screw rod axial feeds has been effectively ensured in the effect for showing axial feeding.The standard of driver slot one end can be with Play the role of identifying initial position and final position, avoids driver slot both ends from causing to obscure, help quickly to judge the amount of feeding. In actual production, standard can be convex block either hole.
As a kind of realization method, the operating parts includes the operating lever being hinged on insulating bar hypomere, operating lever middle part It is hinged with deflecting bar, deflecting bar upper end is hinged by down hinge with insulating bar lower end, under the insulating bar of deflecting bar both sides The sliding rail being slidably matched with down hinge is installed in section, sliding rail length direction is arranged in parallel with insulating bar length direction.
It is hinged with deflecting bar lower end in the middle part of operating lever because operating lever one end is hinged on insulating bar, so when pushing behaviour When making the bar other end, it is equivalent to be moved with lever pushing deflecting bar, it is very laborsaving.When pushing operating lever to lower swing, operation Bar is pulled down insulating bar by deflecting bar, and the upper drive link upper end put will push upper cover to fasten to pedestal by upper connecting rod at this time On.Conversely, push in operating lever when putting, the drive link upper end of the bottom will be pulled open from pedestal upper cover by upper connecting rod, complete It uncaps action, operation is very simple.Deflecting bar upper end is hinged by down hinge and insulating bar lower end, and is set on insulating bar hypomere There is the sliding rail being slidably matched with down hinge both ends, and the extending direction of sliding rail is consistent with insulating bar extending direction, therefore sliding rail can Down hinge is oriented to and is limited to play the role of, that is, deflecting bar upper end is oriented to and is limited, such deflecting bar Can play the role of becomes insulating bar by operating lever oscillatory forces slides up and down power.
As an improvement, the insulating bar includes in Your Majesty's bar being screwed together successively from the top down, several masters Bar lower end is equipped with identical inner bolt hole in bar and a main lower beam, Your Majesty's bar lower end and master, bar upper end and main lower beam upper end in leading Equipped with the external screw section with inner bolt hole threaded, the insulating bar includes in a pair being screwed together successively from the top down The secondary lower beam of bar and one in bar, several pairs, secondary upper boom lower end and it is secondary in bar lower end be equipped with identical secondary inner bolt hole, it is secondary on bar End and secondary lower beam upper end are equipped with the secondary external screw section with secondary inner bolt hole threaded, further include that can bar in pair be mounted on bar in master Above, secondary lower beam is mounted on main lower beam, and can made when external screw section is tightened in inner bolt hole in secondary upper boom, pair under bar and pair The double rod orienting device of bar coaxial arrangement.
Because Your Majesty's bar, it is main in bar lower end be equipped with identical inner bolt hole, it is main in bar and main lower beam upper end is equipped with and inner bolt hole Matched external screw section so whether bar can be screwed to Your Majesty's bar lower end in main lower beam or which root master, and is led down Bar can be spirally connected bar lower end in upper any one master, and bar can be screwed together up and down in arbitrary two or more masters, Therefore bar and main lower beam in Your Majesty's bar of insulating bar, master, can be freely combined, freely assemble according to the actual height of lower cross-line, It is very convenient.Corresponding, bar and secondary lower beam can also be freely combined, freely assemble in secondary upper boom, pair, a combination thereof or group Assembling structure, combination or building block principle are similar, not described in detail herein.
Further include double rod orienting device in this electric power sets up cross-line device, double rod orienting device pacifies bar in pair in structure It is mounted on main lower beam on bar in master, by secondary lower beam.For convenience of narration, the composite structure of Your Majesty's bar and secondary upper boom is known as The composite structure of main lower beam and secondary lower beam is known as lower beam by upper boom, bar during the composite structure of bar in bar in master and pair is known as.It is double Bar orienting device can not only play above-mentioned installation connection function, and also having makes middle bar correspondence be installed on upper boom, middle bar is made to correspond to It is installed in another on bar, and lower beam is made to correspond to the effect being installed on middle bar or upper boom.Specifically, the outer spiral shell of bar in main When section is tightened to completely in Your Majesty's bar inner bolt hole, it can easily make very much bar and secondary upper boom consistency from top to bottom in pair, it thus can be very Bar correspondence in pair is tightened to secondary upper boom lower end easily, plays energy when bar in docking or orienting Your Majesty's bar and master The effect of bar in rapid abutting joint or the secondary upper boom of orientation and pair.Since bar is mounted in master on bar, secondary lower beam is mounted under master in pair On bar, so after above-mentioned docking, insulating bar and insulating bar be mutually clamped or limit, plays the role of interlocking, is avoided from structure When lifting or holding insulating bar, caused because rotation insulating bar is not intended to it is main in bar and Your Majesty's bar the de- phenomenon of reverse rotation, In either main bar with it is main in bar reverse rotation take off phenomenon it is either main in bar and main lower beam the de- phenomenon of reverse rotation or Your Majesty's bar Reverse rotation with main lower beam takes off phenomenon, and it is reliable also to ensure that the insulating bar reliability that is spirally connected of segmentation and insulating bar segmentation are spirally connected Property.
As a kind of realization method, the double rod orienting device include be arranged in master bar upper and lower part and with bar in pair The middle set of cooperation is slided up and down, bar middle part is coaxially installed with middle nut in pair, and main lower beam top is equipped with and is slided up and down with secondary lower beam Cooperation is trapped, and bar upper end and main lower beam upper end are coaxially installed with optical axis section in master, and positioning sliding block is installed on optical axis section outer wall, Inner bolt hole bottom coaxially extends the optical axis chamber for being equipped with and coordinating with optical axis section, and inner bolt hole inner wall is equipped with and slides axially with positioning sliding block The positioning runner of cooperation, optical axis cavity wall are equipped with the locator slide coupled with positioning runner inner end, locator slide and inner bolt hole The setting of screw thread spiral in the same direction and be slidably matched with positioning sliding block spiral, when positioning sliding block turns to locator slide end, in pair Bar outer wall lower end is installed with attribute block corresponding with positioning runner in bar and secondary lower beam coaxial arrangement in bar, pair, Your Majesty's bar and master, Secondary lower beam includes the lower secondary lower beam hinged with deflecting bar and the upper secondary lower beam that is spirally connected with bar in pair, and lower pair lower beam upper end is coaxially affixed There are straight-bar, straight-bar upper end to be coaxially connected with turntable, upper pair lower beam lower part is equipped with turns chamber, upper pair with what straight-bar, turntable were rotatably assorted Lower nut is coaxially installed on lower beam.
