Description

Technical Field

[0001] The invention belongs to the field of ultra-high voltage electric power infrastructure, and in particular relates to an overhead split conductor bundling method and a bundling mechanism. Background Art

[0002] The installation of spacer bars for overhead split transmission lines is of great significance in power engineering. The spacer bar is a rigid support with the same number of mounting parts as the overhead transmission lines, and each mounting part corresponds to a fixed overhead transmission line. Therefore, the premise for installing the spacer bar is that the spacing between multiple conductors should be a predetermined length, otherwise, the spacer bar cannot be installed.

[0003] At present, the installation of spacers for overhead split transmission lines is done manually. Specifically, after the conductors are erected and before power is supplied, workers ride on multiple overhead transmission conductors or stand on the installation platform of the suspension and overhead transmission conductors, move to the position where the spacers are to be installed and prepare for the installation of the spacers. Since the overhead transmission conductors are affected by gravity or external airflow, the distance between multiple conductors can easily exceed the allowable installation position of the spacers. Therefore, when installing the spacers, workers need to manually adjust the position of each overhead split transmission line, and then manually complete the installation of the spacers. The installed spacers should be perpendicular to the extension direction of the overhead split transmission lines.

[0004] However, this implementation method is entirely achieved manually, and as the scale of transmission line construction continues to expand, traditional manual installation methods face problems such as low efficiency, high risk, and insufficient operational precision. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an overhead split conductor bundling method and a bundling mechanism, which can simplify or replace manual bundling operations on overhead split transmission lines, thereby greatly improving the installation efficiency and operation accuracy of spacer bars, while greatly reducing the risk of operation.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows.

[0007] An overhead split conductor harnessing method is provided, wherein the split conductors are divided into multiple pairs along a vertical direction, and any one pair of the split conductors is used as a reference conductor, and the remaining at least one pair of the split conductors is used as a conductor to be adjusted, comprising the following steps: Step S1: making a pair of reference wires located in a horizontal plane, and making a horizontal distance between the pair of reference wires a reference transverse splitting distance; Step S2: sequentially move multiple pairs of adjustable conductors on a vertical plane so that each pair of adjustable conductors has the same or different predetermined horizontal deviation distance with a pair of reference conductors, and each pair of adjustable conductors has the same or different predetermined vertical deviation distance with a pair of reference conductors.

[0008] Preferably, the split conductor is a four-split conductor, and the top pair of split conductors is used as a reference conductor.

[0009] Further, in step S2, the plurality of pairs of adjustable conductors are moved on a vertical plane by vertically and horizontally moving the plurality of pairs of adjustable conductors, and the predetermined horizontal deviation distance is "0".

An overhead split conductor harnessing mechanism is used to harness an overhead split conductor group, and comprises: a base frame, which is vertically arranged on the spacer assembly platform, and the base frame is rotatably provided with a suspension groove wheel, and the rotation axis is perpendicular to the extension direction of the split conductor, and the groove wheel circumference of the suspension groove wheel cooperates with the uppermost overhead split conductor, so that the suspension groove wheel is suspended on the uppermost overhead split conductor, and the uppermost overhead split conductor is the above-mentioned reference conductor, and the remaining overhead split conductors are the above-mentioned conductors to be adjusted. A conductor adjustment unit comprises an adjustment substrate and an adjustment groove wheel arranged on the adjustment substrate, the adjustment substrate is arranged on the base frame and is movable in the vertical direction, and the adjustment groove wheel is movable in the inter-group direction, and is used to simultaneously constrain the conductor to be adjusted in the vertical direction and the inter-group direction through the groove circumference and drive the conductor to be adjusted to move in the vertical direction.

[0011] Preferably, the center distance between the suspension groove wheels of the two overhead splitting groups is the above-mentioned reference lateral splitting distance.

[0012] Furthermore, the suspension groove wheel is arranged on the base frame through a suspension bracket, and the suspension bracket has various specifications, thereby forming various reference transverse splitting distances.

[0013] Preferably, the guide adjustment unit includes a horizontal moving component, which includes a horizontal drive motor, a drive screw, a horizontal guide rail, a drive slider and an adjustment groove wheel. The horizontal drive motor and the horizontal guide rail are both fixed on the adjustment substrate, and the horizontal guide rail extends along the inter-group direction. The drive screw is arranged on the output shaft of the horizontal drive motor and is threadedly connected to the drive slider. The drive slider is provided with a horizontal moving guide shoe that cooperates with the horizontal guide rail, and the drive slider is provided with an adjustment groove wheel.

[0014] Furthermore, a magnetic entity is fixed on the driving slider, and a reed switch electrically connected to the horizontal driving motor is provided on the adjustment substrate. The reed switch is used to control the driving slider to stop, and when the driving slider stops, the suspension groove wheel corresponds to the adjustment groove wheel in the vertical direction.

[0015] Preferably, the guide adjustment unit includes a vertical moving component, which includes an adjustment base plate, a vertical guide rail, a guide rack, a vertical drive motor and a reduction gear pair.

Because the overhead split conductor bundling method of the present invention, first, makes a pair of reference conductors located in the horizontal plane, and makes the horizontal distance of the pair of reference conductors the reference transverse splitting distance; secondly, moves a plurality of pairs of adjustable conductors in sequence on the vertical plane, so that each pair of adjustable conductors has the same or different predetermined horizontal deviation distances with the pair of reference conductors, and makes each pair of adjustable conductors have the same or different predetermined vertical deviation distances with the pair of reference conductors, therefore, the present invention can simplify or replace the manual bundling operation of the overhead split transmission line, thereby greatly improving the installation efficiency and operation accuracy of the spacer, while greatly reducing the risk of operation.

[0019] 2. Because in the present invention, multiple pairs of adjustable conductors are moved on a vertical plane by vertical linear movement and horizontal linear movement, therefore, the present invention conveniently realizes two-dimensional movement of the conductors to be adjusted on a vertical plane by superposition of two linear movements.

[0020] 3.

[0021] 4. Because the suspension groove wheel of the present invention is set on the base frame through the suspension bracket, and the suspension bracket has various specifications, thereby forming a variety of reference lateral splitting distances, the present invention can adapt to the assembly implementation of spacer bars under various different installation conditions and different reference lateral splitting distances by installing suspension brackets of different specifications.

[0022] 5. Because the driving slider of the present invention is fixed with a magnetic entity, and the adjustment substrate is provided with a reed switch electrically connected to the horizontal driving motor, the reed switch is used to control the driving slider to stop, and when the driving slider stops, the suspension groove wheel corresponds to the adjustment groove wheel in the vertical direction.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following embodiments and the accompanying drawings specifically illustrate the overhead split wire bundling method and bundling mechanism of the present invention. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0030] The overhead split conductor harnessing method S100 in this embodiment divides the split conductors into multiple pairs along the vertical direction, and uses any one pair of the split conductors as reference conductors, and uses at least one other pair of split conductors as conductors to be adjusted. Specifically, the split conductors are four split conductors, and the top pair of split conductors is used as reference conductors.

[0031] like Figure 1 As shown, the overhead split wire harness method S100 includes the following steps.

[0032] Step S1: Make a pair of reference conductors located in a horizontal plane, and make the horizontal distance between the pair of reference conductors be a reference transverse splitting distance.

[0033] Specifically, the spacer bars are installed at equal intervals along the extension direction of the split conductors. Since the spacer bars are rigid supports, the prerequisite for their installation is that the intervals between the two of the four split conductors meet the predetermined distance requirements before the spacer bars can be installed. In this embodiment, a pair of reference conductors are located in the horizontal plane through a spacer bar assembly platform. The spacer bar assembly platform has a walking mechanism for extending the split conductors, and the spacer bar assembly platform has a line adjustment mechanism for adjusting a pair of reference conductors to the horizontal plane.

[0034] Step S2: sequentially move multiple pairs of adjustable conductors on a vertical plane so that each pair of adjustable conductors has the same or different predetermined horizontal deviation distance with a pair of reference conductors, and each pair of adjustable conductors has the same or different predetermined vertical deviation distance with a pair of reference conductors.

[0035] The plurality of pairs of adjustable conductors are moved on a vertical plane by vertically and horizontally moving the plurality of pairs of adjustable conductors, and the predetermined horizontal deviation distance is "0".

[0036] like Figure 2As shown, the overhead split conductor harnessing mechanism 100 in this embodiment is arranged on the spacer assembly platform F, and the overhead split conductor is divided into two overhead split conductor groups T along the horizontal direction based on the vertical symmetry plane, and the horizontal direction perpendicular to the vertical symmetry plane is used as the inter-group direction D. An overhead split conductor harnessing mechanism 100 is used to harness an overhead split conductor group T. Specifically, the split conductors are four split conductors, the top pair of overhead split conductors are the above-mentioned reference conductors T0, and the pair of overhead split conductors located below the reference conductor T0 are the above-mentioned conductors to be adjusted T1. The spacer assembly platform F is a platform frame with uniform mass that is hoisted on the reference conductor T0 through a groove wheel. Due to the uniform mass and fixed width, when it is hoisted on the reference conductor T0, a pair of reference conductors T0 are both pressed into the same horizontal plane, and an overhead split conductor harnessing mechanism 100 is symmetrically arranged on the opposite sides of the spacer assembly platform F along the inter-group direction D, thereby realizing the harnessing of the two overhead split conductor groups T.

[0037] Specifically, the wiring harnessing work is to keep a predetermined distance between multiple split wires, so as to avoid the split wires from overlapping under the blowing of external ambient airflow.

[0038] like Figure 3 As shown, the overhead split wire harness mechanism 100 includes a base frame 10 and a wire adjustment unit 20 .

[0039] The base frame 10 is vertically arranged on the spacer rod assembly platform F, and a suspension bracket 11 and a suspension groove wheel 12 are arranged on the base frame 10 .

[0040] The suspension bracket 11 is fixed on the base frame 10 and extends along the inter-group direction D. The suspension groove wheel 12 is rotatably arranged at the end of the suspension bracket 11 away from the base frame 10. The suspension groove wheel 12 is a "V"-shaped groove wheel, and the rotation axis is perpendicular to the extension direction of the split conductor, and the groove wheel circumference of the suspension groove wheel 12 cooperates with the topmost overhead split conductor, that is, the reference conductor T0, so that the suspension groove wheel 12 is suspended on the reference conductor T0. Specifically, the center distance of the suspension groove wheels 12 of the two overhead split conductor harnessing mechanisms 100 is the reference lateral splitting distance in the above method.

[0041] The suspension bracket 11 has various specifications in the extension length extending along the inter-group direction D, so that when the suspension brackets 11 of different specifications are arranged on the spacer bar assembly platform F, various reference transverse splitting distances are formed between the two suspension groove wheels 12 .

[0042] The wire adjustment unit 20 includes a vertical moving component 21 and a horizontal moving component 22 .

[0043] like Figure 4As shown, the vertical moving assembly 21 includes an adjustment base plate 211 , a vertical guide rail 212 , a guide rack 213 , a vertical driving motor 214 and a reduction gear pair 215 .

[0044] The adjustment substrate 211 is arranged on the base frame 10 and is movable in the vertical direction. The vertical guide rail 212 and the guide rack 213 are both fixed on the base frame 10 and extend vertically. The adjustment substrate 211 is provided with a vertical movable guide shoe 2111 that cooperates with the vertical guide rail 212. The vertical drive motor 214 is fixed on the adjustment substrate 211, and the output shaft extends along the inter-group direction D. The reduction gear pair 215 is arranged on the output shaft of the vertical drive motor 214, and the reduction side of the reduction gear pair is meshed with the guide rack to form a vertically driven gear rack mechanism. Specifically, the vertical guide rail 212 and the guide rack 213 are parallel and located in the same vertical plane. In the present embodiment, the vertical guide rail 212 and the guide rack 213 correspond to each other in the horizontal direction.

[0045] Specifically, when the vertical drive motor 214 is activated, the reduction gear pair 215 and the guide rack 213 form a gear rack moving mechanism, and the adjustment base plate 211 moves in the vertical direction relative to the base frame through the vertical moving guide shoe 2111 and the vertical guide rail 212 .

[0046] like Figure 5 As shown, the horizontal moving assembly 22 includes a horizontal driving motor 221 , a driving screw 222 , a horizontal guide rail 223 , a driving slider 224 and an adjusting groove wheel 225 .

[0047] The horizontal driving motor 221 and the horizontal guide rail 223 are both fixed on the adjustment substrate 211. The horizontal guide rail 223 extends along the inter-group direction D. The driving screw 222 is arranged on the output shaft of the horizontal driving motor 221 and is threadedly connected to the driving slider 224. The driving slider 224 is provided with an adjustment groove wheel 225.

[0048] The driving slider 224 is provided with a horizontally movable guide shoe 2241 which cooperates with the horizontal guide rail 223, so that the horizontal moving assembly 22 forms a horizontally driven screw slider mechanism, so that the adjustment groove wheel 225 can be movable along the inter-group direction D, so that the adjustment groove wheel 225 is used to constrain the wire to be adjusted through the groove circumference along the vertical direction and the inter-group direction D at the same time and drive the wire to be adjusted to move in the vertical direction. Specifically, the adjustment groove wheel 225 is a "V"-shaped groove wheel.

[0049] Specifically, when the horizontal driving motor 221 is activated, the driving slider 224 moves along the inter-group direction D by driving the lead screw 222 .

[0050] A magnetic entity 2242a is also fixedly provided on the side of the driving slider 224 along the inter-group direction. The adjustment substrate 211 has a reed switch 2242b electrically connected to the horizontal driving motor 221. The reed switch 2242b is used to control the driving slider 224 to stop. When the driving slider 224 stops, the suspension groove wheel 12 corresponds to the adjustment groove wheel 225 in the vertical direction.

[0051] The working process of the overhead split conductor harness mechanism 100 is described below in conjunction with an embodiment.

[0052] First, the spacer assembly platform F is moved along the extension direction of the splitting guide, so that the overhead split wire harness mechanism 100 is located near the installation position of the spacer S. Then, the adjusting groove wheel 225 is located below the wire to be adjusted T1 along the intergroup direction by the vertical moving component 21. Then, the V-groove of the adjusting groove wheel 225 is located below the wire to be adjusted T1 along the vertical direction by the horizontal moving component 22, and the wire to be adjusted T1 is embedded in the V-groove of the adjusting groove wheel 225 by the vertical moving component 21. Then, the horizontal moving component 22 is used to adjust the V-groove of the adjusting groove wheel 225. The adjusting groove wheel 225 drives the conductor T1 to be adjusted to move along the inter-group direction D, and triggers the reed switch 2242b through the magnetic entity 2242a, so that the horizontal drive motor 221 stops. At this time, the reference conductor T0 and the conductor T1 to be adjusted correspond vertically, which is the premise for the installation of the composite spacer bar S. At this time, the four split conductors constrained by the suspension groove wheel 12 and the adjusting groove wheel 225 are distributed in the same way as the four edges of the same right quadrangular prism. Finally, the installation of the spacer bar S on the four split conductors is completed by the manipulator mounted on the spacer bar assembly platform F.

[0053] The above-mentioned implementation modes are preferred cases of the present invention and are not used to limit the protection scope of the present invention. Various deformations or modifications that can be made by ordinary technicians in this field without creative work within the scope of the attached claims are still within the protection scope of this patent.
