DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-6 This application is described in further detail.

[0030] The embodiment of the present application discloses an adjustable rigid jumper spacer bar, which is used to rigidly space six-split split conductors.

[0031] Embodiment 1: Reference Figure 1 and Figure 2 The spacer bar includes a frame 1, six movable parts 2, six clamps 3, six glands 4, twelve elastic pads 5 and a plurality of positioning components 7. The frame 1 is used as a mounting carrier for other structures of the spacer bar; the movable parts 2 facilitate the spacer bar to adjust the spacer bar according to the different line spacings of the split conductors; the clamps 3 and glands 4 cooperate to clamp the split conductors; the elastic pads 5 are used to protect the split conductors and can improve the clamping effect of the split conductors; the positioning components 7 can fix the movable parts 2 on the frame 1.

[0032] The frame 1 is in an overall circular ring structure, and the movable member 2 is in an overall rectangular parallelepiped structure. The movable member 2 is movably mounted on the frame 1 along the radial direction of the frame 1, and the movable direction of the movable member 2 is parallel to its own length direction; during the movement of the movable member 2, a portion is maintained to cooperate with the frame 1, and six movable members 2 are distributed in a circular array on the frame 1 with the axis of the frame 1 as the axis, and during the movement of the movable member 2, the six movable members 2 are spaced apart from each other at the ends on the inner side of the frame 1. In this embodiment, the frame 1 is preferably in an I-shaped cross section, so that when the split wires exert an extrusion force on the frame 1 toward the middle during the use of the spacer bar, the impact strength of the extrusion force on the frame 1 can be effectively dispersed.

[0033] The six chucks 3 correspond to the six movable parts 2 one by one, and the chucks 3 are fixedly installed at one end of the movable part 2 away from the center of the frame 1; the six pressure caps 4 correspond to the six chucks 3 one by one, the pressure caps 4 are rotatably connected to the corresponding chucks 3, and the rotation axis of the pressure caps 4 is parallel to the axis of the frame 1; when the pressure caps 4 rotate to the extreme position in the direction close to the corresponding chucks 3, a clamping space 6 for the split wire to pass through and be clamped will be formed between the pressure caps 4 and the corresponding chucks 3. In this embodiment, it is preferred that the rotation connection position of the pressure caps 4 and the corresponding chucks 3 is located at one end of the chuck 3 away from the corresponding movable part 2, and when the clamping space 6 is preferably formed between the pressure caps 4 and the corresponding chucks 3, the relative position between the pressure caps 4 and the corresponding chucks 3 can be fixed by a stop pin, thereby improving the reliability of clamping the split wire; since the stop pins with the above-mentioned functions are the prior art in this field, they are not described here in detail, and they are omitted in the drawings.

[0034] The elastic pad 5 is an arc-shaped sheet structure as a whole. The twelve elastic pads 5 correspond to the six clamps 3 and the six glands 4 respectively, and the twelve elastic pads 5 are fixedly installed on the six clamps 3 and the six glands 4 respectively; when the clamping space 6 is formed between the gland 4 and the corresponding clamp 3, the corresponding two elastic pads 5 will be located in the clamping space 6, and the two will be assembled to form an annular structure and distributed at the edge of the clamping space 6. At this time, the gland 4 and the corresponding clamp 3 will clamp and position the split conductor through the corresponding two elastic pads 5. In this embodiment, the elastic pad 5 is preferably made of rubber material, which has the characteristics of anti-aging, anti-ultraviolet, and high temperature resistance; at this time, the friction between the elastic pad 5 and the part of the split conductor passing through the clamping space 6 is increased, and with the help of the shrinkability of the rubber, the spacer rod can play a compensatory role when the split creep occurs during use, effectively avoiding the relative slip of the split conductor and improving the stability of the spacer rod in practical applications; since the elastic pad 5 with the above-mentioned function is a prior art in this field, it will not be described here, and it is only briefly represented in the attached drawings.

[0035] The positioning assembly 7 includes a positioning member 71 and a locking member 72. The positioning member 71 is a bolt structure as a whole, and the locking member 72 is a nut structure as a whole, and the locking member 72 can be matched with the end thread of the tail of the positioning member 71. In this embodiment, the spacer preferably includes six positioning assemblies 7 in total, and the six positioning assemblies 7 correspond to the six movable members 2 one by one, so as to fix the position of the corresponding movable members 2 relative to the frame 1.

[0036] The frame 1 is provided with a through hole 11 for the tail of the positioning member 71 to pass through, and the movable member 2 is provided with a plurality of positioning holes 21 for the tail of the positioning member 71 to pass through and to match, and the plurality of positioning holes 21 are evenly spaced on the movable member 2 along the length direction of the movable member 2; when the movable member 2 moves relative to the frame 1 until a positioning hole 21 on it is aligned and connected with the adjacent through hole 11, the tail of the positioning member 71 is simultaneously passed through the through hole 11 and the positioning hole 21 until the head of the positioning member 71 contacts and abuts against the frame 1, and the end of the tail of the positioning member 71 will pass through the frame 1, and when the locking member 72 is threadedly matched with the positioning member 71 until the locking member 72 contacts and abuts against the frame 1, the movable member 2 will be fixed relative to the frame 1. In this embodiment, since the principle of the positioning component 7 having a positioning effect on the movable member 2 is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0037] The implementation principle of an adjustable rigid jumper spacer in the embodiment of the present application is: The user can adjust the spacer bar according to the different line spacings of the split conductors, control the movement of the six movable parts 2 relative to the frame 1, and then fix the relative position of the movable parts 2 on the frame 1 through the corresponding positioning components 7, so that the line spacing between the six split conductors installed on the spacer bar can meet the requirements, thereby effectively ensuring that the spacer bar can prevent the split conductors from whipping each other, suppress breeze vibration and sub-spacing oscillation, etc.

[0038] Embodiment 2: Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 lies in the frame 1, the movable part 2 and the positioning assembly 7, and the spacer rod also includes three linkage assemblies 8 for controlling the movement of the movable part 2.

[0039] The frame body 1 is an annular structure with a rectangular cross section as a whole, and the three linkage components 8 are all installed on the frame body 1 .

[0040] The six movable parts 2 include three active movable parts 2 and three driven movable parts 2, wherein the three active movable parts 2 are for users to control their movable adjustment, the three driven movable parts 2 correspond to the three active movable parts 2 one by one, and the driven movable parts 2 will be adjusted along with the movable adjustment of the corresponding active movable parts 2; the active movable parts 2 and the corresponding driven movable parts 2 are respectively located at two ends of the same radial direction on the frame 1, and the three active movable parts 2 are distributed in a circular array on the frame 1 with the axis of the frame 1 as the axis.

[0041] The positioning assembly 7 is used to position the active movable part 2 , so it is preferred that the spacer bar includes three positioning assemblies 7 in total, and the three positioning assemblies 7 correspond to the three active movable parts 2 one by one.

[0042] The linkage assembly 8 includes a linkage ring 81 and two linkage wheels 82 . When the active movable member 2 moves relative to the frame 1 , the linkage assembly 8 can drive the corresponding driven movable member 2 to move in the opposite direction relative to the frame 1 .

[0043] The linkage ring 81 is an overall circular ring structure, which is rotatably installed inside the frame 1, and its rotation axis coincides with the axis of the frame 1; the three linkage rings 81 are all located on one side of the movable part 2 along the axis direction of the frame 1, and the three linkage rings 81 are evenly spaced on the frame 1 along the axis direction of the frame 1.

[0044] The linkage wheel 82 is a cylindrical structure as a whole, and is rotatably installed inside the frame 1, and its rotation axis is parallel to the rotation axis of the linkage ring 81; the two linkage wheels 82 are respectively located on one side of the same group of corresponding active movable parts 2 and one side of the driven movable parts 2, and the two linkage wheels 82 are located at both ends of the same radial direction on the frame 1, and the six linkage wheels 82 are distributed in a circular array on the frame 1 with the axis of the frame 1 as the axis.

[0045] The active movable part 2 has a rack structure on one side close to the adjacent conditional wheel along its length direction, and the outer side of the linkage wheel 82 has a gear structure, and the gear structure on the linkage wheel 82 meshes with the rack structure on the adjacent active movable part 2; the two linkage wheels 82 are both located on the inner side of the linkage ring 81, and the inner side of the linkage ring 81 has a gear ring structure, and the gear ring structure on the linkage ring 81 meshes with the gear structures on the corresponding two linkage wheels 82. In this embodiment, it is preferred that the axial dimensions of the three linkage wheels 82 are equal, and the linkage wheels 82 each have a structure that gives way to the gear ring structures of the other two linkage rings 81.

[0046] At this time, controlling an active movable member 2 to move and adjust relative to the frame 1 can drive its adjacent linkage wheel 82 to rotate, thereby driving the corresponding other linkage wheel 82 to rotate synchronously and in the same direction through the linkage ring 81, and then driving the corresponding driven movable member 2 to move synchronously and in the opposite direction.

[0047] The implementation principle of an adjustable rigid jumper spacer in the embodiment of the present application is: In the process of adjusting the spacer bars according to the different line spacings of the split conductors, it is only necessary to control the three active movable parts 2 to move relative to the frame 1, so that the corresponding three driven movable parts 2 can be driven to move synchronously and reversely relative to the frame 1 through the linkage assembly 8, which can effectively improve the efficiency of adjusting the spacer bars and effectively reduce the operational difficulty during the process of adjusting the spacer bars.

[0048] Embodiment 3: Reference Figure 5 and Figure 6 The difference between this embodiment and embodiment 2 lies in the movable part 2, the locking component and the linkage component 8, and the spacer bar also includes three adjustment components 9.

[0049] The movable member 2 is directly and movably connected to the frame body 1 , and the movable member 2 can be fixed relative to the frame body 1 after being moved relative to the frame body 1 , without the need for a locking component to fix its position.

[0050] The three linkage components 8 are replaced by three adjustment components 9 , which can not only realize the effect of the linkage component 8 making the corresponding two movable parts 2 move synchronously and in opposite directions, but also can further facilitate the staff to adjust the movable position of the movable part 2 relative to the frame 1 .

[0051] The adjustment assembly 9 includes an adjustment ring 91, two adjustment wheels 92 and an adjustment member 93. The structure, installation position and method of the adjustment ring 91 on the frame 1 are the same as the structure, installation position and method of the linkage ring 81 on the frame 1, which is used to facilitate the staff to control and adjust the two movable parts 2 at the same time through the adjustment assembly 9; the structure, installation position and method of the adjustment wheel 92 on the frame 1 are the same as the structure, installation position and method of the linkage wheel 82 on the frame 1, which is used to facilitate the staff to control the movable adjustment of the movable part 2 through the adjustment assembly 9; the adjustment member 93 facilitates the staff to operate the adjustment assembly 9.

[0052] The adjusting member 93 is a cylindrical structure as a whole, and is rotatably mounted on the outside of the frame 1, and its rotation axis is perpendicular to the rotation axis of the adjusting ring 91 and coincides with the radial direction of the frame 1 at its position; the adjusting member 93 is located on one side of the corresponding adjusting ring 91 along the axis direction of the frame 1, one end of the adjusting member 93 is located inside the frame 1 and has a gear structure, and the side of the adjusting ring 91 close to the corresponding adjusting member 93 has a rack structure distributed along a circular trajectory with its own axis as the axis, and the rack structure on the adjusting ring 91 is meshed with the gear structure on the corresponding adjusting member 93. In this embodiment, it is preferred that the end of the adjusting member 93 away from the frame 1 has a structure that is convenient for the staff to control its rotation.

[0053] At this time, controlling the adjusting member 93 to rotate relative to the frame 1 can drive the corresponding adjusting ring 91 to rotate relative to the frame 1, thereby driving the corresponding two adjusting wheels 92 to rotate synchronously and in the same direction relative to the frame 1, and further driving the corresponding two movable members 2 to move synchronously and in opposite directions relative to the frame 1.

[0054] Furthermore, in order to effectively ensure the position stability of the spacer rod during use, reduce the probability of the spacer rod's overall center of gravity being offset due to the active adjustment of the movable part 2, and thereby effectively ensure the spacer rod's ability to prevent the split conductors from whipping each other, suppress breeze vibration and sub-span oscillation, etc., it is preferred that three adjustment members 93 are distributed in a circular array on the frame 1 with the axis of the frame 1 as the axis, and the rotation axis of the adjustment member 93 is preferably perpendicular to the activity direction of the corresponding movable part 2.

[0055] Furthermore, in order to further reduce the probability of the spacer bar's overall center of gravity being offset due to the movable adjustment of the movable part 2, the adjustment assembly 9 preferably also includes a plurality of counterweights 94 for adjusting the overall center of gravity of the spacer bar and a plurality of guide rods 95 for assisting the displacement adjustment of the counterweights 94.

[0056] The guide rod 95 is a rod-shaped structure as a whole. The guide rod 95 is installed on the outside of the frame 1 and is located on one side of the corresponding adjustment member 93. One end of the guide rod 95 is fixedly connected to the frame 1 and the other end extends outward in a direction parallel to the rotation axis of the corresponding adjustment member 93. In this embodiment, the adjustment assembly 9 preferably includes two guide rods 95, and the two guide rods 95 are respectively located on both sides of the corresponding adjustment member 93; and the two guide rods 95 are preferably distributed on the frame 1 along the annular direction of the frame 1.

[0057] The counterweight 94 is a rectangular parallelepiped structure and is located on one side of the frame 1 in the radial direction; the counterweight 94 is sleeved and matched with two guide rods 95 at the same time, and the corresponding adjustment member 93 passes through the counterweight 94 and is threadedly matched with the counterweight 94; at this time, while controlling the rotation of the adjustment member 93, the corresponding counterweight 94 can also be driven to move along the rotation axis direction of the adjustment member 93. In this embodiment, the preferred adjustment assembly 9 includes a counterweight 94.

[0058] When the adjusting member 93 rotates to drive the corresponding two movable members 2 to move synchronously in a direction away from the center position of the frame body 1 , the adjusting member 93 will drive the corresponding counterweight member 94 to move in a direction away from the frame body 1 .

[0059] The implementation principle of an adjustable rigid jumper spacer in the embodiment of the present application is: In the process of adjusting the spacer bar according to the different line spacings of the split conductors, it is only necessary to control the rotation of the adjusting member 93 to drive the corresponding two movable members 2 to move synchronously and in the opposite direction relative to the frame 1 through the adjusting assembly 9, which can further improve the efficiency of adjusting the spacer bar and effectively improve the accuracy of adjusting the spacer bar. During the process of adjusting the spacer bar, if the movement of the movable part 2 causes the center of gravity of the spacer bar to shift, the displacement of the counterweight 94 can cause the center of gravity of the spacer bar to shift in the opposite direction, thereby effectively reducing the degree of the center of gravity shift of the spacer bar after the movable part 2 is adjusted.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
