For solving the problem, the design feature of this electric stringing cross-line device is: comprise the base affixed with insulating bar upper end, base top is provided with the bottom tub of through base rear and front end, the return pulley of holder download cable is installed in bottom tub, base avris is hinged with the upper cover that can fasten to base upper end by hinge, on cover and be provided with the upper cover slot corresponding with bottom tub, by adjusting device, auxiliary wheel is installed in upper cover slot, adjusting device can regulate the degree of depth of auxiliary wheel in upper cover slot, return pulley and auxiliary wheel periphery are provided with the annular groove coordinated with cable, base outer wall below hinge is installed with support bar, support bar end is hinged with drive link, drive link upper end thereof has upper connecting rod, upper small end is corresponding hinged with the upper cover outer wall above hinge, on drive link hypomere, slip cap is equipped with upper sliding sleeve, the insulating rod along insulating bar to downward-extension is hinged with in the middle part of upper sliding sleeve, insulating bar is installed with and sliding sleeve in insulating rod axial sliding fit, insulating bar top is provided with the swing chamber coordinated with drive link hypomere, insulating rod hypomere is provided with the operating parts driving insulating rod to move axially.

This electric stringing cross-line device is that realized by adjustable clamp compact form rolling supporting structure can rapid-assembling or erection, can complete cross-line, take-up, lead-in wire function on ground, simple to operate, without the need to ascending a height, fail safe is high.

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, the function that upper cover can rotate to realize being fastened on base around hinge or raise from base.Base is provided with bottom tub, bottom tub horizontal-extending through base two ends, bottom tub be mainly through cable provide and pass through space.For convenience of describing, in horizontal plane, direction of both ends through for bottom tub is called front and rear, its closure is called longitudinal direction, the direction of bottom tub both sides is called left and right, and its direction connected is called transverse direction, the direction of vertical level is called vertical or vertical direction.In bottom tub, return pulley is installed, the axial line horizontally set of return pulley rotating shaft.Roller by play rolling support pass the effect of cable, reduce through frictional force, improve through smoothness and ensure that the integrality of cable skin.On cover and be also provided with the upper cover slot corresponding with bottom tub, upper cover slot also through upper cover two ends is arranged.When upper cover fastens on base, upper cover slot and bottom tub will link into an integrated entity up and down.For convenience of describing the cavity that upper cover slot and bottom tub linked into an integrated entity up and down or through slot is called " conveying trough " or " full groove ", the state that upper cover and base snap together is called buckling state or closure state, upper cover is called the state of raising or opening from the state that base is raised.Be provided with auxiliary wheel in upper cover slot, auxiliary wheel is arranged on by adjusting device and covers.The rotating shaft core line of auxiliary wheel is also the extended or horizontally set in left and right, and like this, when buckling state, auxiliary wheel rotating shaft and return pulley shaft parallel are arranged.Because return pulley and auxiliary wheel periphery are provided with the annular groove coordinated with cable, so, when buckling state between auxiliary wheel and return pulley by the gap of a formation similar circle or cavity, this gap or cavity are exactly the cavity that passes through of cable when transmitting cable.For convenience of describing, this cavity is called " transmission cavity " or " cable chamber ".The Main Function of adjusting device regulates the depth position of auxiliary wheel in upper cover slot, is exactly the spacing of auxiliary wheel and return pulley when regulating buckling state, namely regulates size or the thickness of transmission cavity.When 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 describing, this mated condition of auxiliary wheel and return pulley is called " delivery status " or " smooth and easy state ".When transmission cavity is thinner than upper cross-line cable,

In this electric stringing cross-line device, base is also installed with support bar, support bar connects the below of hinge between upper cover and base.Support bar end is hinged with a drive link, and drive link upper end thereof has upper connecting rod, and upper small end is corresponding hinged with the upper boom part above hinge.Because upper connecting rod and drive link go up hinged cooperation each hinge and be all generally and hinge between upper cover and base be arranged in parallel, instead of it is vertically disposed, therefore when 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, so also just achieves the fastening or unlimited driving upper cover.On drive link hypomere, slip cap is equipped with upper sliding sleeve, upper sliding sleeve is hinged with the insulating rod vertically extended downwards, and insulating bar is installed with the middle sliding sleeve of the suit insulating rod that slides, like this, the action of insulating rod is just defined as and can only slides up and down by sliding sleeve.Insulating rod lower end is provided with operating parts, can insulating rod be driven easily to move up and down by move operation part, now the power slided up and down of insulating rod can be divided into the power that driving drive link hypomere moves up and down and the power that upper sliding sleeve is slided up and down along drive link by the upper sliding sleeve of insulating rod upper end, so just upper cover can be driven to complete fastening or unlimited action by the transmission of drive link and upper connecting rod.Specifically, when driving insulating rod to move up by operating parts on the ground, insulating rod upper end will driving drive link lower end be moved and drive link upper end be moved down, now drive link upper end will by upper connecting rod by upper cover from pull-up base, also just complete the upper cover controlled on the ground above insulating bar and open wide or action of uncapping.Otherwise when driving insulating rod to move down by operating parts, support bar will drive upper cover to fasten on base by upper connecting rod, also just complete the upper cover controlled on the ground above insulating bar and fasten or buckle closure action.For convenience of describing, the upper cover controlled on the ground above insulating bar is carried out uncap or all transmission mechanisms of buckle closure action are called control mechanism far away.

When control mechanism far away coordinates with adjusting device, just can realize three kinds of functions: fixed clamp is lived in that cross-line cable end crosses lower cross-line cable opposite side (cross-line or more line) from lower cross-line cable side, fixed clamp lives in cross-line cable end and guided forward, pulls upper cross-line cable (lead-in wire), chosen by upper cross-line cable and highly to keep and relation of lifting (take-up) that upper cross-line cable is smooth and easy, stable above lower cross-line.

By operation adjusting device, the thickness of transmission cavity can be controlled.When 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 upper cover and base during smooth and easy transmission, are switched to buckling state by needs cable 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.When cable transmits in cable chamber, by cable Action of Gravity Field, generally only have return pulley can carry out rolling support and spacing by its annular groove to cable bottom and both sides, bottom, only when cable upwards rocks and departs from return pulley, auxiliary wheel just can carry out rolling support and spacing by its annular groove to cable top and both sides, top, therefore cable surrounding can be subject to auxiliary wheel and return pulley compares the rolling support and rolling position-limiting action that there are " elasticity ", the scope of activities of cable in transmission cavity is larger, such cable just can smooth and easy movement in transmission cavity, freely can also be raised by base and upper cover or reduce transmission cavity inner cable and transfer rate and the epidermis intact of cable can not be affected.Delivery status be adapted at cross-line cable striden across lower cross-line and upper cross-line is inserted in transmission cavity time rolling support cable transmit use fast.For convenience of describing, this mated condition of auxiliary wheel and return pulley is called " delivery status " or " smooth and easy state ".

When transmission cavity is thinner than upper cross-line cable, under the driving of control mechanism far away, upper cover is pressed on base, and upper cross-line cable clamping is lived by auxiliary wheel and return pulley, now goes up cross-line cable and is relatively fixed in transmission cavity.Specifically, the auxiliary wheel under buckling state moves down by operation adjusting device, namely by auxiliary wheel from the lifting of upper cover slot bottom land, now auxiliary wheel and return pulley spacing reduce, and transmission cavity becomes than transmitting cable that namely to go up cross-line cable thin.Like this, under buckling state, auxiliary wheel and return pulley will to upper cross-line cable generation upper and lower " chucking power " by upper cross-line cable clamping transmission cavities, upper cross-line cable and base, upper boom is relative is fixed together, and now by insulating bar, the upper cross-line cable end clamped can be crossed opposite side by lower cross-line side.For convenience of describing, this mated condition of this auxiliary wheel and return pulley is called " clamp position " or " clamped condition ".

When stringing needs cross-line, general this electric stringing of needs two 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 operating first set electric stringing cross-line device again makes it clamp cross-line cable front portion, then upper cross-line cable front portion is crossed lower cross-line cable opposite side (front) by lower cross-line cable side (rear) by upper insulating bar of lifting, and so just achieves cross-line or gets over line.The control mechanism far away of second step operation second cover electric stringing cross-line device clamps the upper cross-line cable front portion (being equivalent to complete lead-in wire function) crossing lower cross-line cable front.First set electric stringing cross-line device is removed from upper cross-line cable and is operated adjusting device and makes it be switched to delivery status by the 3rd step, finally its upper cover and base sheath is installed on upper cross-line cable, this completes the smooth and easy take-up to upper cross-line cable.Under the take-up of first set electric stringing cross-line device lifts effect, lift the second cover electric stringing cross-line device when moving forward, just can by upper cross-line cable from lower cross-line side (rear) far away constantly to opposite side (front) cross-line or more line.

As a kind of implementation, described adjusting device comprises framework, framework comprises two vertical poles be arranged in parallel and is arranged on the Inter cross bar of vertical pole corresponding end, cross bar two ends are linked together by transverse axis and vertical pole, cross bar rotates around transverse axis, auxiliary wheel correspondence is arranged between two vertical poles, the screw rod also comprising the screw inside and outside through upper cover and coordinate with screw, screw rod upper surface is provided with driver slot, screw rod lower end is coaxially installed with extension rod, extension rod lower end is coaxially installed with the diameter disk larger than extension rod, be provided with in the middle part of cross bar and extension rod, the horizontal chamber that disk rotational coordinates.

Because framework comprises two vertical poles and two cross bars that are formed by connecting by transverse axis, and auxiliary wheel is arranged between two vertical poles, so when framework is elevated, auxiliary wheel is also inevitable to be elevated thereupon.Be provided with horizontal chamber in the middle part of cross bar, in horizontal chamber, be loaded with extension rod and the disk of screw rod lower end.Because screw rod, extension rod and disk are all coaxial settings, and the diameter of disk is greater than extension rod diameter, so screw rod can only be rotated around screw rod axial line by extension rod and disk opposing rail, and can not slide up and down along screw rod axial line.On cover and be provided with two screws, two screw rods at framework two ends respectively with two corresponding threaded of screw, so when in the corresponding screw of screw rod precession, framework is lifted on by two screw rods in the upper cover slot of upper cover.Screw rod outer end is provided with driver slot, and when promoting driver slot and rotate outside upper cover, screw rod is by relative screw precession or back-out.Now because framework can not rotate with screw rod, so framework can only move along screw axial under the drive of disk and extension rod, namely deeply go up cover slot bottom land or away from upper cover slot bottom land, also just achieve the lifting of auxiliary wheel.Because cross bar coordinates by transverse axis and the longitudinal axis are hinged, therefore when turn screw rod, two screw rods can be asynchronous, and namely first lifting frame one end lifting frame other end again, avoids not convenience during synchronous turn screw rod.

As improvement, be installed with slide block outside vertical pole, the length direction of slide block is vertical with the length direction of vertical pole to be arranged and be arranged in parallel with screw axial, and upper cover slot cell wall is provided with the chute that be slidably matched corresponding to slide block.

At vertical pole arranged outside slide block, and the chute that coordinates with skid is set on upper cover slot sidewall, can plays when framework is elevated and carry out the effect of fore-and-aft direction relative limit, and by frame installation in cover slot time, can also guiding function be played.Because the length direction of slide block and screw axial be arranged in parallel, therefore slide block and being slidably matched of chute can ensure that the driving underframe at screw rod can only do stable elevating movement
