Description

Technical Field

[0001] This invention relates to the field of spacer technology, and more specifically to a spacer installation and removal device for guiding and limiting spacers. Background Technology

[0002] In the field of high-voltage line operation and maintenance, spacers are key components for ensuring line safety. Their installation and dismantling operations have formed a relatively mature operation system. Currently, the industry is equipped with a variety of special tools, and is also gradually combining drones, connecting components and other equipment to assist in the operation, so as to adapt to the high-voltage line layout in different scenarios and improve the convenience and coverage of the operation.

[0003] Existing high-altitude guide wires, due to their own weight or the presence of other detection components, will naturally bend or shift, making it impossible for the guide wires at the installation location to achieve an ideal straight installation shape. This makes it impossible for the spacer installation tool to specifically adjust the relative position of the guide wire and clamp when dealing with curved pipelines. Furthermore, the clamping stability of the guide wire during operation is insufficient, and it lacks adaptability to guide wires of different diameters. This limits the adaptability and efficiency of the operation process, reducing the installation accuracy and efficiency of the spacer. At the same time, during the disassembly process, the condition of the guide wire can also prevent the disassembly tool from aligning with the spacer, which also reduces the disassembly efficiency. Summary of the Invention

[0004] The technical problem to be solved by this invention is that in complex environments, conductors may exhibit non-ideal straight conductor shapes such as natural bending or offset, which reduces the installation efficiency and accuracy of spacers and the efficiency of subsequent disassembly processes. The purpose is to provide a guide and limit spacer installation and disassembly device to solve the above-mentioned technical problems.

[0005] The present invention provides the following apparatus:

[0006] A guide and limit spacer rod installation and removal device includes a connecting assembly for connecting the spacer rod and a side clamp assembly for adjusting the alignment of the conductor axis direction with the axis of the connecting assembly.

[0007] The side clamp assembly includes two relatively movable clamping blocks with a gap between them. The side clamp assembly has a guiding state and a clamping state. In the guiding state, the gap between the two clamping blocks is at its maximum distance, which is used to adjust the wire in the horizontal direction to a state coaxial with the connecting component. In the clamping state, the gap between the two clamping blocks is at its minimum distance, the sides of the clamping blocks are in contact with the sides of the wire, and the opposite sides of the two clamping blocks enclose the clamping opening of the side clamp assembly.

[0008] Furthermore, there are two side clamping assemblies, which are coaxially distributed at the left and right ends of the connecting assembly; the two clamping blocks of each side clamping assembly are fixedly connected to the two output ends of the corresponding power cylinder.

[0009] Furthermore, both clamping blocks are provided with inclined grooves, which are positioned opposite each other on both sides of the clamping opening. When clamped, the two inclined grooves cooperate to form a clamping opening and fit around the circumference of the wire to prevent the wire from moving horizontally during installation.

[0010] Furthermore, the side clamp assembly also includes a power cylinder for pulling the two clamping blocks to move relative to each other. A sliding rod is horizontally movably arranged at one end of the power cylinder corresponding to the clamping block. The power cylinder and the sliding rod are each provided with sliding holes that pass through both sides, and the axes of the sliding holes are parallel to each other. A connecting plate is provided above the clamping block corresponding to the sliding rod. One end of the sliding hole of the sliding rod is fixedly connected to the side of the connecting plate.

[0011] Furthermore, there are four sliding rods, which are arranged parallel to each other; the four sliding rods are arranged in pairs at both ends of the power cylinder; the two sliding rods at one end are arranged diagonally inside the power cylinder, and the two sliding rods at the other end are staggered from the two sliding rods at the first end.

[0012] Furthermore, the side of the clamping block closest to the clamping opening is a wear-resistant component, which slides in contact with the outer wall of the wire.

[0013] Furthermore, a first guide rod is provided below the clamping block for guiding the wire to the gap. The top end of the first guide rod is fixedly provided on the side of the clamping block and is guided to the gap between the clamping blocks.

[0014] Furthermore, the guide rods are set at an angle, with the ends of the two guide rods close to each other near the clamping block, and the ends away from the clamping block set far apart from each other.

[0015] Furthermore, the connecting assembly includes two movable plates that move relative to each other along the axial direction. A second guide rod is vertically arranged below the movable plates, and the top end of the second guide rod is fixedly arranged on the movable plates. The top end of the second guide rod is guided to the space between the two movable plates.

[0016] Furthermore, the side clamp assembly also includes an alignment plate vertically arranged near the connecting component, with a pre-alignment opening recessed at the bottom of the alignment plate, the pre-alignment opening being designed to align with the axis of the connecting component.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] 1. This invention uses a side clamp assembly to clamp and guide the conductor until it is parallel and coaxial with the clamping assembly. With the side clamp assembly guiding the device, it is hoisted above the offset conductor and guided into the clamping opening by the side clamp assembly, and adjusted horizontally to be parallel to the connecting assembly. The side clamp assembly is then activated to clamp the conductor, at which point the clamping block adheres to the conductor, and the device can slide along the conductor's axis, remaining coaxial with the side clamp assemblies at both ends on the horizontal plane. The device continues to move downwards, further adhering the middle of the conductor to the connecting assembly until it enters the clamping assembly. At this point, the clamping assembly is activated, completing the connection between the spacer and the offset conductor, improving the accuracy and efficiency of spacer installation.

[0019] 2. In the disassembly process, this invention uses a side clamping assembly to clamp and guide the wire with the spacer bar installed, guiding it to a state parallel to the connecting assembly. The device is then hoisted above the wire with the spacer bar installed, and the side clamping assembly guides the wire into the clamping opening. The side clamping assembly is activated to clamp the wire, with the clamping block adhering to the wire. At this point, the connecting assembly is above the spacer bar, and the device can slide along the axis of the wire. The side clamping assemblies at both ends are coaxial with the wire on a horizontal plane. The device is then moved downwards to bring the connecting assembly in the middle of the device closer to the spacer bar at the same horizontal height. The connecting assembly is then activated to complete the alignment and connection of the connecting assembly and spacer bar. Subsequently, the connection between the spacer bar and the wire is disconnected, thus completing the disassembly of the spacer bar. This improves the accuracy and efficiency of the spacer bar disassembly process. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0028] Example 1:

[0029] A guide and limit spacer rod installation and removal device includes a connecting component 1 for connecting the spacer rod and a side clamp component 2 for adjusting the alignment of the conductor axis with the axis of the connecting component 1. The connecting component 1 is used to connect the end connecting clamp of the spacer rod, and the device is fixed to the spacer rod through the connecting component 1. The side clamp components 2 are distributed at both ends of the connecting component 1 to ensure that the conductor can be accurately connected to the connecting component 1 after adjustment by the side clamp components 2. The device includes a mounting plate for installation, and the side clamp components 2 are all fixedly screwed to the mounting plate by bolts. The connecting component 1 fixes the device to the end connection of the spacer rod through its own friction and the insertion post.

[0030] Specifically, the side clamp assembly 2 includes two relatively movable clamping blocks 3. The two clamping blocks 3 have a symmetrical structure and are symmetrically distributed along the axis of the connecting assembly 1. A gap is reserved between the two clamping blocks 3 for the wire to enter. The size of the gap can be adjusted by the relative movement of the clamping blocks 3, thereby realizing the switching of the two working states of the side clamp assembly 2. The side clamp assembly 2 is clearly set with a guiding state and a clamping state. The two states are switched by the relative displacement of the clamping blocks 3. During the switching process, each component is driven by an air pump, and the movement trajectory of each component can complete the stroke action in one go, avoiding the adjustment process of the mounting alignment action and reducing the complexity of completing the state switching. In the guiding state, the two clamping blocks 3 move in a direction away from each other until the gap between the two clamping blocks 3 reaches the maximum distance. At this time, the opening size of the gap is larger than the outer diameter of the wire, and the central axis of the gap is collinear with the axis of the connecting assembly 1. In this state, the device The conductor can be moved above the offset conductor by hoisting. With the assistance of external force or guiding structure, the conductor enters the gap between the two clamping blocks 3. The side clamping assembly 2 adjusts the posture of the conductor in the horizontal direction through the guiding effect of the gap, so that the conductor axis gradually becomes collinear with the axis of the connecting assembly 1, ensuring that the conductor can be accurately connected to the connecting assembly 1 later. In the clamping state, the two clamping blocks 3 move in a direction that approaches each other until the gap between the two clamping blocks 3 reaches the minimum distance. At this time, the side of the clamping block 3 is tightly attached to the side of the conductor. The opposite sides of the two clamping blocks 3 form the clamping mouth of the side clamping assembly 2. The outline of the clamping mouth is adapted to the outer periphery of the conductor. The clamping mouth and the side of the conductor form a surface contact fit, which not only achieves stable clamping of the conductor, but also ensures the sliding freedom of the conductor along its own axis, ensuring a stable environment and the alignment of the conductor for the subsequent installation or removal of the spacer.

[0031] Preferably, two side clamping assemblies 2 are provided at both ends of the wire. The two side clamping assemblies 2 have completely identical structures and are symmetrically distributed along the axis of the connecting assembly 1. They are fixedly installed at both ends of the connecting assembly 1. The central axes of the two side clamping assemblies 2 are collinear with the central axis of the connecting assembly 1, ensuring that the overall axis of the wire can be precisely aligned with the axis of the connecting assembly 1 after adjustment by the two side clamping assemblies 2. A power cylinder 4 for pulling the two clamping blocks 3 relative to each other is fixedly provided between the two clamping blocks 3 of the side clamping assembly 2. The power cylinder 4 is a linear drive component, and the cylinder body is fixedly installed at the middle position between the two clamping blocks 3. The output direction of the power cylinder 4 is consistent with the movement direction of the clamping blocks 3. The output end of the power cylinder 4 is perpendicular to the axis of the connecting assembly 1. Extending horizontally; the two output ends of the power cylinder 4 are fixedly connected to the opposite sides of the two clamping blocks 3 respectively; through the extension and retraction of the output end of the power cylinder 4, the two clamping blocks 3 are directly pulled to achieve relative movement of moving closer or further away from each other, thereby driving the side clamping assembly 2 to switch between the guiding state and the clamping state; when the output end of the power cylinder 4 is fully extended, it pulls the two clamping blocks 3 away from each other, and the gap reaches the maximum distance, and the side clamping assembly 2 switches to the guiding state; when the output end of the power cylinder 4 is retracted, it pulls the two clamping blocks 3 closer to each other, and the gap gradually decreases to the minimum distance, and the side clamping assembly 2 switches to the clamping state. The driving stroke of the power cylinder 4 directly determines the adjustment range of the gap, which can adapt to wires with different outer diameters and avoid the wires slipping out of the clamp due to insufficient clamping force.

[0032] Preferably, each of the two clamping blocks 3 has an integrally formed inclined groove 5, which is located on the opposite side of the clamping blocks 3, i.e., on the side surfaces of the two clamping blocks 3 facing each other. The structures of the two inclined grooves 5 are completely symmetrical. The groove openings are set opposite to each other, and the cross-section of the inclined groove 5 is a "V" shape to ensure that it can form a tangential fit with the outer peripheral side of the conductor. When the side clamping assembly 2 is in the clamping state, the two clamping blocks 3 move closer to each other, and the groove walls of the two inclined grooves 5 gradually fit with the outer peripheral side of the conductor, eventually forming a complete clamping opening. The cross-section of the clamping opening is circular or an arc shape adapted to the outer peripheral side of the conductor. The inner wall of the clamping opening fully fits with the outer peripheral side of the conductor, forming a stable clamping fit. Through the enclosing structure of the inclined groove 5, the conductor can be limited from multiple angles in the horizontal direction, restricting the displacement of the conductor in the horizontal direction and preventing the conductor from deviating during operation.

[0033] Preferably, wear-resistant parts 6 are attached to the inner walls of the inclined grooves 5 of the two clamping blocks 3 by means of adhesive or bolts. The wear-resistant parts 6 are sheet-like structures, and their shape is perfectly matched to the inner wall contour of the inclined grooves 5. The inner surface of the wear-resistant parts 6 is in direct contact with the outer wall of the wire, and the outer surface is tightly attached and fixed to the inner wall of the inclined grooves 5. The wear-resistant parts 6 are made of smooth polyethylene material or wear-resistant material with ceramic coating. When the side clamping assembly 2 is in the clamping state and the wire slides along its own axis, the wear-resistant parts 6 can directly bear the friction between the wire and the clamping blocks 3, avoiding wear of the inner wall of the inclined grooves 5 due to long-term friction. At the same time, the inner surface of the wear-resistant parts 6 maintains an appropriate roughness to ensure the clamping friction between the clamping blocks 3 and the wire, and reduce the wear on the outer wall of the wire.

[0034] Specifically, a sliding rod 7 is horizontally movably mounted on one end of the power cylinder 4 corresponding to the clamping block 3. The sliding rod extends horizontally in the same direction as the output direction of the power cylinder 4. The sliding rod 7 is connected to the cylinder body of the power cylinder 4 via a sliding fit. A sliding hole 8 is provided on the cylinder body of the power cylinder 4 at the mounting position of the sliding rod 7, penetrating both sides of the power cylinder 4. The axis of the sliding hole 8 coincides with the axis of the sliding rod 7, and the axes of the multiple sliding holes 8 are parallel to each other, ensuring that the sliding rod 7 can slide smoothly along the axis of the sliding hole 8. A connecting plate 9 is fixedly mounted above the clamping block 3 at the position corresponding to the sliding rod 7. The connecting plate 9 is perpendicular to the extension direction of the sliding rod 7. The connecting plate 9 is fixedly connected to the top surface of the clamping block 3 on one side and to one end of the sliding rod 7 on the other side. The end of the sliding rod 7 away from the connecting plate 9 passes through the sliding hole 8 of the power cylinder 4 and is fixedly connected to the output end of the power cylinder 4, forming a power transmission path. When the power cylinder 4 drives the output end to extend or retract, the driving force is transmitted to the connecting plate 9 through the sliding rod 7, thereby driving the clamping block 3 to move along the axis of the sliding hole 8. The sliding hole 8 guides the sliding of the sliding rod 7, ensuring that the movement trajectory of the clamping block 3 remains straight, avoiding the clamping block 3 from deviating or jamming during movement, and improving the smoothness and reliability of the state switching of the side clamping assembly 2.

[0035] Preferably, four sliding rods 7 are provided, and the four sliding rods 7 are distributed parallel to each other to ensure that the movement direction of each sliding rod 7 remains uniform; the four sliding rods 7 are arranged in groups of two, respectively, at both ends of the power cylinder 4. A group of sliding rods 7 is provided on each side of the power cylinder 4 near the two clamping blocks 3. The two sliding rods 7 at any end are diagonally distributed along the radial direction of the power cylinder 4, and the axes of the two sliding rods 7 form a diagonal relationship on the cross-section of the power cylinder 4. Simultaneously, the two sliding rods 7 at the other end are staggered with the two sliding rods 7 of the previous group in the radial direction of the power cylinder 4. The latter group of sliding rods 7... The axis is located in the gap between the axes of the previous set of sliding rods 7 on the cross-section of the power cylinder 4. Through the diagonal and staggered distribution, the driving force transmitted from the power cylinder 4 to the clamping block 3 can be more even, avoiding the clamping block 3 from tilting due to uneven force during movement, ensuring that the two clamping blocks 3 always move in parallel, and thus ensuring that the central axis of the clamp formed by the inclined groove 5 is always collinear with the axis of the connecting component 1, improving the accuracy of wire adjustment. At the same time, the setting of four sliding rods 7 can enhance the stability of power transmission, disperse the force borne by a single sliding rod 7, and extend the service life of the device.

[0036] Preferably, a first guide rod 10 for guiding the wire into the gap is provided below the clamping block 3. The first guide rod 10 is a rigid rod, and one first guide rod 10 is provided below each of the two clamping blocks 3. The top end of the first guide rod 10 is fixed to the side of the clamping block 3 by welding or bolting, specifically at the lower part of the clamping block 3 near the gap. The bottom end of the first guide rod 10 extends away from the clamping block 3, and the top end extends to the entrance of the gap between the two clamping blocks 3, forming a guide channel. The main purpose of the first guide rod 10 is to accurately guide the offset wire into the gap between the two clamping blocks 3 when the side clamping assembly 2 is in the guiding state, avoiding the wire from being unable to enter the gap smoothly due to offset, and improving the convenience and accuracy of wire guidance. When the device is hoisted above the wire, the wire slides along the rod of the first guide rod 10 under the action of gravity or external auxiliary force, and is finally guided into the gap between the two clamping blocks 3, so as to continue the subsequent vertical adjustment of the wire.

[0037] Specifically, the first guide rods 10 are inclined, with the inclination directions of the two first guide rods 10 corresponding to each other, forming a trumpet-shaped guide structure. Specifically, the distance between the ends of the two first guide rods 10 closest to the clamping block 3 is smaller than the distance between the ends furthest from the clamping block 3, and the first guide rods 10 gradually incline inward from the end furthest from the clamping block 3 to the end closest to the clamping block 3. This inclined distribution structure results in a larger opening at the entrance of the guide channel formed by the two first guide rods 10, accommodating a wider range of wire deviation, while the smaller opening at the exit end matches the gap entrance size between the two clamping blocks 3, achieving a gradual transition in the guide channel and forming flexible guidance. When the wire enters from the entrance of the guide channel, under the guidance of the first guide rods 10, it gradually converges inward, ultimately precisely entering the gap between the two clamping blocks 3, used to adjust wires with large deviations.

[0038] Specifically, the connecting assembly 1 includes two movable plates 12 that can move relative to each other along the axial direction. The two movable plates 12 are parallel and opposite to each other, and their extension direction is perpendicular to the axis of the connecting assembly 1. The movable plates 12 are connected to the base of the connecting assembly 1 through a guide rail slider mechanism to ensure that the two movable plates 12 can move smoothly relative to each other along the axial direction of the connecting assembly 1. A second guide rod 13 is vertically arranged below the movable plates 12. The extension direction of the second guide rod 13 is perpendicular to the axis of the connecting assembly 1 and extends vertically. The second guide rod 13 is fixedly connected to the bottom end face of the movable plates 12 by welding or threaded connection, and the other end extends vertically downward away from the movable plates 12, extending into the area between the two movable plates 12. The main purpose of the guide rod 13 is to guide the spacer bar into the connection area between the two moving plates 12. When the spacer bar is disassembled, the spacer bar slides along the body of the second guide rod 13 under the action of external force. The spacer bar is precisely guided between the two moving plates 12, ensuring that the spacer bar clamp is positioned in the middle of the two moving plates 12. This ensures that after the moving plates 12 move relative to each other to the clamping state, the spacer bar can be clamped and subsequent disassembly can be performed. At this time, the two moving plates 12 move relative to each other along the axial direction to align and connect the connecting assembly 1, ensuring that the moving plates 12 move relative to each other to clamp the spacer bar and perform subsequent disassembly. This avoids the spacer bar from shifting during disassembly and improves the disassembly efficiency and accuracy of the spacer bar.

[0039] Specifically, the side clamp assembly 2 also includes an alignment plate 11 vertically arranged near the side of the connecting assembly 1. The alignment plate 11 is a rectangular plate structure, and its extension direction is perpendicular to the axis of the connecting assembly 1. The alignment plate 11 is installed on the base of the side clamp assembly 2 by bolts. The specific installation position is at the end of the side clamp assembly 2 near the connecting assembly 1, and the plate surface of the alignment plate 11 is arranged in the vertical direction. The bottom of the alignment plate 11 is recessed with a pre-alignment opening 14, which is an arc-shaped groove with a cross-sectional profile that matches the outer periphery of the wire. The central axis of the pre-alignment opening 14 is collinear with the axis of the connecting assembly 1. After the conductor is guided and adjusted to a roughly collinear state by the side clamp assembly 2, the conductor will enter the pre-alignment port 14 of the alignment plate 11. The pre-alignment port 14, through the arc-shaped inner wall cooperating with the outer periphery of the conductor, performs the final precise alignment of the conductor, ensuring that the conductor axis is completely collinear with the axis of the connecting assembly 1, providing the highest precision position guarantee for the subsequent installation or removal of the spacer. The pre-alignment port 14 adds an alignment process between the side clamp assembly 2 and the connecting assembly 1, further improving the alignment accuracy of the device and effectively solving the problem of insufficient installation accuracy caused by conductor offset in complex environments.

[0040] In actual operation, the overall operation process of the device is as follows: First, the device is moved above the conductor to be operated by the hoisting equipment. At this time, the side clamping assembly 2 is in the guiding state under the drive of the power cylinder 4, the two clamping blocks 3 are separated from each other, and the gap reaches the maximum distance. The first guide rod 10 forms a trumpet-shaped guiding channel, and the pre-alignment opening 14 of the alignment plate 11 is in the docking state. Then, the position of the device is adjusted so that the conductor enters the guiding channel formed by the first guide rod 10. The conductor slides along the inclined first guide rod 10 and is gradually guided into the gap between the two clamping blocks 3. During this process, the posture of the conductor is initially adjusted, and the axis moves closer to the axis of the connecting assembly 1. When the conductor enters the gap, the output end of the power cylinder 4 is driven to retract, pulling the two clamping blocks 3 closer to each other. The side clamping assembly 2 switches to the clamping state, and the inclined grooves 5 of the two clamping blocks 3 form a clamping opening, which is tightly fitted with the outer periphery of the conductor. The wear-resistant part 6 contacts the outer wall of the conductor to achieve stable clamping and limit the horizontal displacement of the conductor. At this point, the conductor slides along its own axis and is finally precisely aligned through the pre-alignment opening 14 of the alignment plate 11, ensuring that the conductor axis is completely collinear with the axis of the connecting component 1. Finally, according to the operational requirements, the device is moved along the conductor axis to adjust the installation position of the spacer. Once the position is determined, the final assembly of the spacer and the conductor is completed. If it is a disassembly operation, the operation is reversed. Guided by the second guide rod 13, the spacer enters between the two moving plates 12 under the guidance of the second guide rod 13, and the connecting component 1 is guided to the two moving plates 12. Then, the two moving plates 12 move relative to each other along the axis, and the moving plates 12 clamp the connecting component 1 to complete the connection between the spacer and the connecting component 1. Finally, the connecting component 1 is driven to disengage the spacer from the conductor, and the side clamping component 2 is driven to switch to the guiding state to separate the device from the conductor, completing the disassembly operation.
