This electric stringing cross-line device is that realize by adjustable clamp compact form rolling supporting structure can rapid-assembling or set up, and can complete on ground cross-line, take-up, lead-in wire function, simple to operate, without ascending a height, safe.
Adjustable clamp compact form rolling supporting structure mainly comprises the base that supported by insulating bar and is hinged on the upper cover on base, and upper cover can rotate to realize around hinge and be fastened on the function of raising on base or from base.Base is provided with bottom tub, and bottom tub horizontal-extending also connects base two ends, bottom tub be mainly through cable provide and pass through space.For convenience of narration, in horizontal plane, the direction of both ends that bottom tub is connected is called front and rear, its closure is called longitudinally, the direction of bottom tub both sides is called left and right, and the direction of its connection is called laterally, and the direction of vertical level is called to vertical or vertical direction.Return pulley is installed, the axial line horizontally set of return pulley rotating shaft in bottom tub.Roller will play the effect of cable that rolling support passes, and has reduced through frictional force, has improved the integrality of passing smoothness and having ensured cable skin.On cover and be also provided with the upper cover slot corresponding with bottom tub, upper cover slot also connects upper cover two ends and arranges.In the time that upper cover fastens on base, upper cover slot and bottom tub will link into an integrated entity up and down.Cavity or the through slot upper cover slot and bottom tub being linked into an integrated entity up and down for convenience of narration is called " conveying trough " or " full groove ", the state that upper cover and base are snapped together is called buckling state or closure state, and the state that upper cover is raised from base is called the state of raising or opening.In upper cover slot, be provided with auxiliary wheel, auxiliary wheel is arranged on and is covered by adjusting device.The rotating shaft core line of auxiliary wheel is also that setting or horizontally set are extended in left and right, and like this, in the time of buckling state, auxiliary wheel rotating shaft and return pulley shaft parallel arrange.Because return pulley and auxiliary wheel periphery are provided with the annular groove coordinating with cable, so, in the time of buckling state, between auxiliary wheel and return pulley, will forming gap or the cavity of a similar circle, this gap or cavity are exactly the cavity that while transmitting cable, cable passes through.For convenience of narration, this cavity is called to " transmission cavity " or " cable chamber ".The Main Function of adjusting device, is that the depth position in upper cover slot regulates to auxiliary wheel, and the spacing of auxiliary wheel and return pulley while regulating buckling state exactly namely regulates size or the thickness of transmission cavity.In the time that transmission cavity is thicker than upper cross-line cable, cable coordinates with the rolling of return pulley, auxiliary wheel makes cable smooth and easy transmission in transmission cavity.For convenience of narration, this mated condition of auxiliary wheel and return pulley is called to " delivery status " or " smooth and easy state ".In the time that transmission cavity is thinner than upper cross-line cable,
In this electric stringing cross-line device, on base, be also installed with support bar, support bar between upper cover and base, connect hinge below.Support bar end is hinged with a drive link, and drive link upper end is hinged with connecting rod, and upper small end is corresponding hinged with the upper boom part of hinge top.Because it is all generally that hinge between upper cover and base be arranged in parallel that upper connecting rod and drive link are gone up hinged cooperation each hinge, instead of vertically disposed, therefore in the time swinging up and down drive link lower end, drive link upper end also can drive connecting rod lower end to swing up and down, again because support bar is relative fixed with hinge, therefore going up swinging up and down of connecting rod lower end can only drive upper cover to swing around hinge by upper small end, has so also just realized and has driven the fastening of upper cover or open wide.On drive link hypomere, slip cap is equipped with upper sliding sleeve, is hinged with the downward insulating rod vertically extending on upper sliding sleeve, being installed with the middle sliding sleeve of the suit insulating rod that slides on insulating bar, and middle like this sliding sleeve is just defined as the action of insulating rod can only slide up and down.Insulating rod lower end is provided with operating parts, can drive easily insulating rod to move up and down by move operation part, now the upper sliding sleeve of insulating rod upper end can be divided into the power sliding up and down of insulating rod the power that drives drive link hypomere to move up and down and the power that upper sliding sleeve is slided up and down along drive link, so just can drive upper cover complete by the transmission of drive link and upper connecting rod and fasten or open wide action.Specifically, while driving insulating rod to move up by operating parts on the ground, insulating rod upper end will be moved on driving drive link lower end and drive link upper end be moved down, now drive link upper end will be by upper connecting rod by upper cover pull-up from base, has also just completed the upper cover of controlling on the ground insulating bar top and has opened wide or the action of uncapping.Otherwise in the time driving insulating rod to move down by operating parts, support bar will drive upper cover to fasten on base by upper connecting rod, upper cover fastening or the buckle closure action of controlling on the ground insulating bar top are also just completed.For convenience of narration, all transmission mechanisms that upper cover is uncapped or buckle closure moves of controlling on the ground insulating bar top are called to control mechanism far away.
In the time that control mechanism far away coordinates with adjusting device, just can realize three kinds of functions: fixed clamp live in cross-line cable end from lower cross-line cable one side cross lower cross-line cable opposite side (cross-line or more line), fixed clamp live in cross-line cable end and guide forward, pull upper cross-line cable (lead-in wire), upper cross-line cable is chosen high to lower cross-line top and keep and the relation of lifting (take-up) that upper cross-line cable is smooth and easy, stable.
By operation adjusting device, can control the thickness of transmission cavity.In the time that transmission cavity is thicker than upper cross-line cable, cable coordinates with the rolling of return pulley, auxiliary wheel makes cable smooth and easy transmission in transmission cavity.Specifically, when needs cable when smooth and easy transmission, is switched to buckling state by upper cover and base in transmission cavity, by adjusting device, auxiliary wheel is upwards regulated, namely upwards cover slot bottom land direction regulates, and now transmission cavity cross section becomes large, thicker than transmitted cable.In the time that cable transmits in cable chamber, be subject to cable Action of Gravity Field, generally only have return pulley to carry out rolling support and spacing to cable bottom and both sides, bottom by its annular groove, only in the time that cable upwards rocks and departs from return pulley, auxiliary wheel just can carry out rolling support and spacing to cable top and both sides, top by its annular groove, therefore cable surrounding can be subject to auxiliary wheel and return pulley relatively has rolling support and the rolling position-limiting action of " elasticity ", the scope of activities of cable in transmission cavity is larger, cable just can smooth and easy movement in transmission cavity like this, can also freely raise or reduce transmission cavity inner cable and can not affect transfer rate and the epidermis integrality of cable by base and upper cover.When delivery status is adapted at cross-line cable and has striden across lower cross-line and upper cross-line and be inserted in transmission cavity, rolling support cable transmits use fast.For convenience of narration, this mated condition of auxiliary wheel and return pulley is called to " delivery status " or " smooth and easy state ".
In the time that transmission cavity is thinner than upper cross-line cable, under the driving of control mechanism far away, upper cover is pressed on base, and auxiliary wheel and return pulley are lived upper cross-line cable clamping, now go up cross-line cable and are relatively fixed in transmission cavity.Specifically, operation adjusting device moves down the auxiliary wheel under buckling state, namely by auxiliary wheel from the lifting of upper cover slot bottom land, now auxiliary wheel and return pulley spacing are dwindled, transmission cavity becomes that namely to go up cross-line cable thin than transmitting cable.Like this, under buckling state, auxiliary wheel and return pulley will be to upper cross-line cable generation upper and lower " chucking power " and by upper cross-line cable clamping transmission cavities, upper cross-line cable with base, upper boom is relative is fixed together, and now can the upper cross-line cable end clamping be crossed to opposite side by lower cross-line one side by insulating bar.For convenience of narration, this mated condition of this auxiliary wheel and return pulley is called to " clamp position " or " clamped condition ".
In the time that stringing needs cross-line, generally need two this electric stringing of cover cross-line device cooperatings.Two cover cover electric stringing cross-line devices are all adjusted to clamped condition by the first step, the control mechanism far away that operates again first set electric stringing cross-line device makes it clamp upper cross-line cable front portion, then the upper insulating bar of lifting crosses lower cross-line cable opposite side (front) by upper cross-line cable front portion by lower cross-line cable one side (rear), has so just realized cross-line or has got over line.The control mechanism far away of second step operation the second cover electric stringing cross-line device clamps the upper cross-line cable front portion (being equivalent to lead-in wire function) that crosses lower cross-line cable front.Adjusting device is removed and operated to the 3rd step by first set electric stringing cross-line device from upper cross-line cable makes it be switched to delivery status, finally its upper cover and base sheath is installed on upper cross-line cable, has so just completed the smooth and easy take-up to upper cross-line cable.Take-up at first set electric stringing cross-line device is lifted under effect, when lifting the second cover electric stringing cross-line device and moving forward, just can be by upper cross-line cable from lower cross-line one side (rear) far away constantly to opposite side (front) cross-line or line more.
