Description

Technical Field

[0001] This invention relates to the field of overhead conductor installation, and specifically to an automatically installable two-split conductor spacer and its installation method. Background Technology

[0002] Spacer bars are devices installed between adjacent conductors, primarily used to maintain spacing between conductors and reduce conductor vibration. Currently, most spacer bars are installed manually at height, which is highly dangerous, technically challenging, and labor-intensive. For split conductors, spacer bars simply separate the two conductors, resulting in a relatively simpler structure. Therefore, automated installation spacer bars for split conductors have been developed, typically installed by robots or drones. However, due to limited visibility at height (e.g., obstructed by conductors, crossarms, jumpers, etc.), positioning accuracy is poor, sometimes leading to misalignment and failure to trigger the spacer, resulting in installation errors. Furthermore, misjudgments frequently occur when releasing the spacer after installation, causing overload and damage to the robot or drone motors. Additionally, the automated installation of existing spacer bars is limited to fixing them to the conductor but lacks anti-loosening properties. In windy seasons, spacer bars often slip off the conductor, making it impossible to separate the conductor at the fixed point. Summary of the Invention

[0003] To address the aforementioned problems, this invention discloses an automatically installable bi-split conductor spacer and its installation method. The bi-split conductor spacer can be automatically installed onto the conductor precisely and conveniently, and has the functions of preventing loosening and detachment after installation.

[0004] An automatically installable two-split conductor spacer includes a support frame, a wing frame, a sliding rod, and a swing locking frame;

[0005] A fin frame is rotatably installed on each of the left and right sides of the support frame. The fin frame includes a fin shell, an outer locking block and an inner locking block. The lower end of the fin shell is provided with a V-shaped opening. The outer locking block is fixedly connected to the outer end of the fin shell. The inner locking block is slidably installed on the part between the outer locking block and the support frame on the fin shell.

[0006] The lower end of the support frame is symmetrically hinged with a swing locking frame on each side. The swing locking frame includes a swing frame housing and a sliding sleeve that slides along the swing frame housing. When the swing locking frame is in a horizontal position, the inner locking block is inserted into the side wall of the sliding sleeve and moves closer to the outer locking block along with the sliding sleeve to clamp the wire.

[0007] The sliding rod is slidably connected to the support frame. The two sides of the lower end of the sliding rod are temporarily engaged with the corresponding wings. The middle part of the lower end of the sliding rod is coaxially hinged to two swing locking frames. The hinge point between the swing locking frame and the support frame is higher than the hinge point between the swing locking frame and the sliding rod.

[0008] Preferably, the outer wall of the sliding sleeve is provided with a protrusion extending along the axial direction. The protrusion is machined with a second long slot. When the sliding sleeve rotates with the swing frame housing to a near-horizontal state, the lower end of the inner locking block is inserted into the second long slot.

[0009] Preferably, the swing locking frame further includes a support rod, a first spring, and a limiting plate. The first spring is fitted outside the support rod, the sliding sleeve is fitted outside the first spring, the limiting plate is engaged with the side of the support rod, and the sliding sleeve is located between the limiting plate and the first spring.

[0010] Preferably, the upper end of the limiting piece is engaged with the swing frame housing, and the lower end of the outer locking block is provided with a top post that cooperates with the limiting piece.

[0011] Preferably, the inner locking block is provided with a self-locking mechanism.

[0012] Preferably, the self-locking mechanism includes a ball bearing and an elastic plug. The upper end of the inner locking block forms a triangular groove with an opening facing the support frame between it and the fin housing. The ball bearing is slidably installed in the triangular groove, and the elastic plug is located at the opening of the triangular groove.

[0013] Preferably, the upper end of the V-shaped opening is elliptical, and the major axis of the ellipse is horizontal.

[0014] Preferably, a limiting rod is provided on each side of the support frame, and the other end of the limiting rod is slidably connected to the fin shell.

[0015] Preferably, a second spring is fitted around the sliding rod, a cutting blade with its edge facing downwards is provided at the upper end of the sliding rod, and a hanging ring is provided at the upper end of the support frame below the cutting blade.

[0016] The present invention also discloses a method for installing the above-mentioned two-split conductor spacer, as follows:

[0017] Step 1: The drone carries the spacer bar of the two-split conductor above the conductor and then moves it downwards;

[0018] Step 2: After the opening of the wing frame touches the wire, it rotates upward to release the locking limit on the sliding rod, and the sliding rod moves downward.

[0019] Step 3: The swing locking frame, which is hinged to the sliding rod, rotates towards the wing frame with the hinge point of the support frame as the center.

[0020] Step 4: The top column pushes the limiting plate out of the swing frame housing, and the inner locking block is inserted into the sliding sleeve. Driven by the sliding sleeve, it moves to the outer locking block, pushing the wire outward and cooperating with the outer locking block to hug the wire, thus realizing the automatic installation of the two-split wire spacer.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This application includes a support frame, a sliding rod slidably mounted on the support frame, a wing frame hinged to the support frame, and a swing locking frame. The wing frame is triggered by a wire to release the constraint on the sliding rod, causing the sliding rod to drive the swing locking frame to rotate towards the wing frame, which cooperates with the wing frame to fix it on the wire, thereby separating the wire and maintaining the spacing.

[0023] 2. By setting external locking blocks and internal locking blocks, this application can keep the wire firmly within the set distance, ensuring accurate and reliable positioning.

[0024] 3. By setting the cutting edge and the cutting blade, this application can achieve the technical effects of automatic triggering of installation and automatic detachment from the drone, which has a high safety factor. Attached Figure Description

Detailed Implementation

[0038] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0039] Example 1

[0040] like Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, the present invention discloses an automatically installable two-split conductor spacer, which mainly includes a support frame 1, a wing frame 2, a sliding rod 5, and a swing locking frame 4.

[0041] The support frame 1 is an inverted U-shaped structure with shells at the front and back and open sides. A through hole is machined at the upper end of the inverted U-shaped structure, and two hanging rings are symmetrically arranged above the through hole. A spring limiting cylinder is provided on the inner side of the top of the inverted U-shaped structure, and a second spring 6 is installed inside the spring limiting cylinder. The second spring 6 is fitted onto the outside of the sliding rod 5. The upper end of the sliding rod 5 protrudes upward from the through hole, and a [feature / feature] is provided on the protruding part of the sliding rod 5. Figure 3 The cutting blade 5.1 shown has its blade facing downwards, and the lower end of the sliding rod 5 is symmetrically arranged with... Figure 4 The sliding rod claw 5.2 shown has a first long slot on the front and rear sides of the support frame 1. Two guide posts are symmetrically arranged on the outer side of the sliding rod 5. When the sliding rod 5 slides along the support frame 1, the guide posts slide with the sliding rod 5 in the first long slot, ensuring that the sliding rod 5 moves vertically in a straight line.

[0042] There are two sets of wing frames 2 and two sets of swing locking frames 4, symmetrically distributed on the left and right sides of the support frame 1. Specifically:

[0043] Each fin assembly includes a fin housing 2.1, an outer locking block 2.3, and an inner locking block 2.2. The lower part of the fin housing 2.1 has an opening in an inverted V-shape. The entire bottom surface of the fin housing 2.1 is machined with a groove, and the outer locking block 2.3 is installed within the groove near the end of the fin. A [specific feature / feature] is provided at the lower end of the outer locking block 2.3. Figure 5 The top post 2.3.1 is shown. An inner locking block 2.2 is slidably installed within the groove of the fin housing 2.1 between the outer locking block 2.3 and the support frame 1. The upper end of the inner locking block 2.2 is machined with a ramp, which forms a triangular groove with the top of the groove in the fin housing 2.1, opening towards the support frame 1. Figure 11 The ball bearing 2.4 shown is slidably installed in the triangular groove, and an elastic block 2.5 is provided at the opening of the triangular groove to limit the movement of the ball bearing 2.4.

[0044] A finned shell 2.1 is symmetrically hinged to each of the left and right sides of the inner sidewall of the support frame 1. A [feature / feature] is provided below the portion of the finned shell 2.1 near the hinge point. Figure 4 The fin hook 2.1.1 is shown. A horizontally oriented limiting hole is machined below the hinge point of the fin shell 2.1. A limiting post is slidably connected within this limiting hole, and a limiting rod 3 is connected to the outer end face of the limiting post. The other end of the limiting rod 3 is fixedly connected to the support frame 1. The limiting rod 3 prevents the fin shell 2.1 from descending or rising indefinitely, ensuring that the fin shell 2.1 can only swing slightly in a near-horizontal state.

[0045] Each set of swing locking frames 4 includes a swing frame housing 4.1, a support rod 4.2, a first spring 4.5, a sliding sleeve 4.3, and a limiting piece 4.4. The support rod 4.2 is installed inside the swing frame housing 4.1, and the first spring 4.5 is fitted onto the outside of the support rod 4.2. Figure 2 and Figure 6 As shown, a sliding sleeve 4.3 is fitted around the lower end of the first spring 4.5 and outside the support rod 4.2. The first spring 4.5 is contracted and confined between the bottom of the sliding sleeve 4.3 and the upper end of the support rod 4.2. The outer wall of the sliding sleeve 4.3 has a protrusion extending along the axial direction, and this protrusion is machined with a second elongated slot. When the sliding sleeve 4.3 rotates with the swing frame housing 4.1 to a near-horizontal state, the lower end of the inner locking block 2.2 is inserted into this second elongated slot. The outer surfaces of the two swing frame housings 2.1 that are far apart from each other are machined as follows... Figure 8 The third long slot shown is interconnected with the second long slot, and the length of the third long slot is greater than the length of the second long slot. Limiting plate mounting holes are machined on the swing frame housing 4.1 outside the third long slot, as shown. Figure 7 As shown, the upper end of the limiting piece 4.4 is provided with a top protrusion 4.4.1, which is inserted into the mounting hole of the limiting piece in the initial position. The middle part of the limiting piece 4.4 is provided with a long slot 4.4.2 in the vertical direction, and the lower edge of the long slot 4.4.2 is engaged in the positioning groove of the support rod 4.2. The limiting piece 4.4 temporarily limits the sliding sleeve 4.3 to the area near the support frame 1 on the swing frame housing 4.1 through the limiting piece mounting hole and the positioning groove. The upper end of the swing frame housing 4.1 is hinged to the support frame 1 at the first hinge point. A second hinge point is provided on the side of the two swing frame housings 4.1 that are close to each other. The position of the second hinge point is lower than the position of the first hinge point. The second hinge point is hinged to the connecting rod 7. The upper end of the connecting rod 7 is hinged to the middle part of the lower end of the sliding rod 5. The two connecting rods 7 are coaxially hinged to the support frame 1.

[0046] The process of installing the bi-split conductor spacer of the present invention onto the bi-split conductor is as follows:

[0047] In the initial state of the split conductor spacer, i.e., before it is installed on conductor 8, the fin hook 2.1.1 is located below the sliding rod claw 5.2, i.e. Figure 4The state shown is as follows. At this time, the fin hook 2.1.1 will restrict the sliding rod 5 from moving downward along the support frame 1. The drone is connected to the hanging ring at the upper end of the support frame 1 by a hanging rope, which transports the two-split wire spacer to the top of the wire 8. The drone descends, and the two-split wire spacer moves downward under the action of gravity. When any part of the V-shaped opening of the fin shell 2.1 touches the wire 8, the wire 8 will push the fin shell 2.1 to rotate upward with its hinge point as the fulcrum. The fin hook 2.1.1 separates from the sliding rod claw 5.2 and loses its restraint on the sliding rod claw 5.2. Under the restoring force of the second spring 6, the sliding rod 5 drives the upper hinge point of the connecting rod 7 to slide downward. When the cutter 5.1 at the top of the sliding rod 5 moves downward with the sliding rod 5, it cuts the hanging rope, and the two-split wire spacer is separated from the drone. The whole process is automatic cutting and does not require manual angle alignment. Under the transmission action of the connecting rod 7, the swing frame housing 4.1 rotates outward around the first hinge point. When it rotates to a near horizontal position, the inner locking block 2.2 just gets into the second long slot of the sliding sleeve 4.3. At this point, the top post 2.3.1 at the lower end of the outer locking block 2.3 just contacts the top protrusion 4.4.1 of the limiting plate 4.4. If the swing frame housing 4.1 continues to rotate, the limiting plate 4.4 will be pushed downward out of the mounting hole by the top post 2.3.1, and the lower edge of the long slot 4.4.2 of the limiting plate 4.4 will disengage from the positioning groove of the support rod 4.2. The sliding sleeve 4.3 will lose its limiting position. Under the restoring force of the first spring 4.5, the sliding sleeve 4.3 will drive the inner locking block 2.2 to slide towards the end of the fin housing 2.1 through the second long slot. During the sliding process, the wire 8 will be pushed to the outer locking block 2.3, and the inner locking block 2.2 and the outer locking block 2.3 will encircle the wire 8. Figure 9 and Figure 10 As shown, the two-split conductor spacer can be stably and securely installed on the two-split conductor. The two locking blocks have grooves machined on opposite sides to circumferentially encircle the conductor 8, providing a stronger and more stable clamping force.

[0048] Because a locking block 2.2 and a finned housing 2.1 are provided with a... Figure 11 As shown, the ball bearing 2.4 and the elastic stopper 2.5 are used to prevent the inner locking block 2.2 from moving towards the center when the wire 8 is pushed laterally in strong winds, causing the two wires to tend to move closer together. This serves to lock the inner locking block 2.2 in place. Since the inner locking block 2.2 is engaged with the sliding sleeve 4.3 and the swing frame housing 4.1 through the second long slot, the two wires 8 are restricted by the two swing frame housings 4.1 and will not move closer together.

[0049] When the outer locking block 2.3 and the inner locking block 2.2 encircle the wire 8, the swing frame housing 4.1 is in a horizontal state, and the two connecting rods 7 hinged to the two swing frame housings 4.1 are in a state as follows. Figure 10The horizontal position mentioned above is exactly the dead point of the connecting rod 7, which also acts as a locking mechanism for the swing frame housing 4.1.

[0050] Example 2

[0051] In this embodiment, the upper end of the V-shaped opening in the fin shell 2.1 is an ellipse with its major axis set horizontally. The locking openings of the outer locking block 2.3 and the inner locking block 2.2 are both arc-shaped, and the arc is located between the two side arcs of the ellipse.

[0052] In this embodiment, both the support frame 1 and the finned shell 2.1 can be flat plate structures. A first long slot is machined on one side of the flat plate support frame, and a guide post is provided on one side of the sliding rod 5 to achieve the guiding function.

[0053] A slide bar or groove is provided on one side of the finned shell 2.1 with a flat structure. The inner locking block 2.2 is slidably installed on the outside of the slide bar or embedded in the groove on the side, which can also realize the sliding of the inner locking block 2.2 along the finned shell 2.1.

[0054] In this embodiment, the second long slot of the sliding sleeve 4.3 and the third long slot of the swing frame housing 4.1 can also be U-shaped slots with a larger opening width.

[0055] Example 3

[0056] In this embodiment, the sliding sleeve 4.3 may not have a protrusion; instead, a second elongated slot or U-shaped groove may be machined directly on the side wall of the sliding sleeve 4.3. Meanwhile, the swing frame housing 4.1 may also be a frame structure without side walls or ends, with the support rod 4.2 supported by connecting rods that form the frame.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
