Description

Technical Field

[0001] This utility model relates to the field of maintenance equipment technology, and more specifically, to a tool for replacing the insulation of a medium-wave transmitting antenna. Background Technology

[0002] A medium-wave transmitting antenna includes an antenna tower and guy wires for fixing the antenna tower. One end of the guy wire is connected to the antenna tower, and the other end is fixed to the ground. Multiple guy wires are arranged around the antenna. The guy wires are taut during installation, so that the multiple guy wires form an antagonistic effect and fix the antenna tower.

[0003] The guy wire connects the ground and the antenna tower, thus requiring an insulation structure. This insulation structure, located in the middle of the guy wire, typically consists of two interlocking insulating frames. An insulating element, usually a barrel-shaped insulating element made of insulating material, is placed between the frames. However, the barrel-shaped insulation of medium-wave guy wires is prone to damage over time. Due to the tension of the guy wire, the force exerted on the insulator between the two insulating frames is relatively large. Without suitable tools, the medium-wave guy wire must be lowered for replacement, which slows down the construction process and prevents normal broadcasting from being restored within a day. Utility Model Content

The insulation structure includes a first insulating frame and a second insulating frame, which are interlocked and tend to move away from each other under the action of a tension wire. The first insulating frame includes a first supporting beam, and the second insulating frame includes a second supporting beam. A first insulator is held between the first and second supporting beams. A second insulator is provided on the side of the beam away from the first insulator; the medium-wave transmitting antenna insulation replacement tool includes: a clamp assembly, a long pull rod, and a drive assembly; the clamp assembly can be sleeved on the pull wire and abut against the connector of the first insulation frame; the drive assembly includes two drive units, the first ends of the two drive units are respectively provided at the ends of the clamp assembly, the second ends of the drive units are connected to the long pull rod, the second ends of the drive units can move relative to the first ends of the drive units along the extension direction of the long pull rod, the long pull rod can be sleeved on the first or second bearing beam, and the drive unit can drive the long pull rod to move closer to or away from the clamp assembly.

[0005] In some embodiments, the clamping assembly includes two spaced-apart clamping bodies and a connector, the connector extending along the spacing direction and being detachably connected to the two clamping bodies respectively.

[0006] In some embodiments, the drive unit includes a connecting frame and a jack. The connecting frame includes a connecting rod and a support bracket. One end of the connecting frame is connected to the support bracket, and the other end is pivotally connected to the clamping plate assembly. The fixed end of the jack is disposed on the support bracket, and the movable end of the jack is connected to one end of a long pull rod, which can push the long pull rod closer to or away from the clamping plate assembly.

[0007] In some embodiments, the long lever is rotatably connected to the movable end of the jack.

[0008] In some embodiments, the long tie rod is U-shaped, with its open end connected to a jack and its bottom end able to be fitted onto a first or second load-bearing beam.

[0009] In some embodiments, the first insulating frame further includes a frame body and a crossbeam, and the insulation structure of the medium-wave transmitting antenna further includes a spring, which is disposed between the second insulator and the crossbeam and pushes the second insulator to press against the second supporting beam; the medium-wave transmitting antenna insulation replacement tool further includes a spring fixing assembly, which is disposed on the crossbeam and includes a fixing ring, an adjusting rod and a bracket, the bracket being disposed on the side of the crossbeam away from the spring, the fixing ring being able to be sleeved and connected to the side of the spring away from the crossbeam, and the adjusting rod being connected to the bracket and the fixing ring respectively, and the adjusting rod being able to drive the fixing ring closer to the bracket.

[0012] In some embodiments, the clamp body is triangular, and the width of the clamp body is greater than the width of the first insulating frame and the second insulating frame.

[0013] To address the problems of insufficient suitable replacement tools, complex replacement process, and large workload in replacing the insulation of medium-wave transmitting antennas, this utility model has the following advantages:

[0014] In the above technical solution, the clamp assembly is designed to be fitted onto the pull wire, so that the center of the pull wire coincides with the center of symmetry of the clamp assembly. This allows the clamp assembly to rotate around the pull wire and to abut against the connector, forming the first fulcrum. The clamp assembly is also designed to be parallel to either the first or second bearing beam, allowing the tool to be adjusted to a suitable position and angle. When replacing the first insulator, a long pull rod can be fitted onto the second bearing beam. The drive assembly moves the long pull rod, further moving the second bearing beam toward the clamp assembly, thus widening the gap between the first and second bearing beams. This reduces the force at both ends of the first insulator, allowing it to be removed and replaced. After replacement, simply adjust the long pull rod to gradually reduce the tension on the second bearing beam and return it to its original position. To replace the second insulator, a long tie rod can be fitted onto the first bearing beam to loosen the bolts securing the first bearing beam. Furthermore, after the bolts are loosened, the distance between the first bearing beam and the clamp assembly can be gradually increased, allowing the first insulator, the second bearing beam, and the second insulator to all move away from the clamp assembly under the force of the lower guy wire. This relaxes the force of the springs supporting the second insulator, reducing the force at both ends of the second insulator, thus enabling the second insulator to be removed and replaced. After replacement, simply adjust the long tie rod to return the first bearing beam to its original position and re-secure it. Attached Figure Description

[0020] This embodiment discloses a tool for replacing the insulation of a medium-wave transmitting antenna, such as... Figures 1-2As shown, this is used for replacing insulators in the insulation structure of a medium-wave transmitting antenna. The insulation structure includes a first insulating frame 11 and a second insulating frame 12. The first insulating frame 11 and the second insulating frame 12 are interlocked and tend to move away from each other under the action of a guy wire. The first insulating frame 11 includes a first supporting beam 113, and the second insulating frame 12 includes a second supporting beam 121. A first insulator 14 is held between the first supporting beam 113 and the second supporting beam 121. A second insulator 15 is provided on the side of the second supporting beam 121 opposite to the first insulator 14. The wire insulation replacement tool includes: a clamping plate assembly, a long pull rod 30, and a drive assembly 40; the clamping plate assembly can be sleeved on the pull wire and abut against the connector 13 of the first insulation frame 11; the drive assembly 40 includes two drive units, the first ends of the two drive units are respectively disposed at the ends of the clamping plate assembly, and the second ends of the drive units are connected to the long pull rod 30; the second ends of the drive units can move relative to the first ends of the drive units along the extension direction of the long pull rod 30; the long pull rod 30 can be sleeved on the first bearing beam 113 or the second bearing beam 121; the drive units can drive the long pull rod 30 to move closer to or away from the clamping plate assembly.

[0021] It should be noted that the first insulating frame 11 and the second insulating frame 12 are respectively connected to the guy wire via the connector 13. The guy wire is usually a steel cable. Although the steel cable is taut, its length can still be changed to a small extent by its elastic deformation. The guy wire applies a force to the first insulating frame 11 and the second insulating frame 12 in a direction away from each other. The first insulating frame 11 and the second insulating frame 12 are connected in the form of a ring (similar to the nested structure between two sections of a chain), with the first insulator 14 sandwiched in the middle. This allows the first insulating frame 11 and the second insulating frame 12 to be connected and to transmit force while maintaining insulation. Therefore, if it is necessary to remove the first insulator 14, it is necessary to adjust the force at both ends of the first insulator 14, that is, adjust one of the first bearing beam 113 and the second bearing beam 121 to move away from each other, thereby reducing the compressive force on the first insulator 14 and thus removing the first insulator 14. The second insulator 15 is disposed on the side of the second supporting beam 121 opposite to the first insulator 14, and its other side abuts against the second supporting beam 121 via an elastic element. Therefore, if it is necessary to remove the second insulator 15, the elastic element can be lengthened by adjusting the second supporting beam 121, reducing the degree of deformation of the elastic element, thereby reducing the abutment force and allowing the second insulator 15 to be removed. It is evident that if the above-mentioned medium-wave transmitting antenna insulation structure is not completely disassembled and the insulator replaced, the position of the first supporting beam 113 or the second supporting beam 121 needs to be adjusted along the extension direction of the guy wire to complete the replacement.

[0022] In summary, in the above technical solution, the clamp assembly is designed to fit over the pull wire, ensuring that the center of the pull wire coincides with the center of symmetry of the clamp assembly. This allows the clamp assembly to rotate around the pull wire and abut against the connector 13. When the drive assembly 40 applies force, the clamp assembly abuts against the connector 13, forming a fulcrum for applying force. Furthermore, the clamp assembly is parallel to the first bearing beam 113 or the second bearing beam 121, allowing the tool to be adjusted to a suitable position and angle. When the first insulator 1... 4. When replacing, the long tie rod 30 can be sleeved onto the second bearing beam 121. The drive assembly 40 drives the long tie rod 30 to move, and further drives the second bearing beam 121 to move towards the clamp assembly, so as to expand the distance between the first bearing beam 113 and the second bearing beam 121, thereby reducing the force at both ends of the first insulator 14, so that the first insulator 14 can be removed and the replacement operation can be completed. After replacement, it is only necessary to adjust the long tie rod 30 to gradually reduce the tension on the second bearing beam 121 and return it to its original position. For replacing the second insulator 15, the long tie rod 30 can be fitted onto the first bearing beam 113 to loosen the bolts securing the first bearing beam 113. Furthermore, after the bolts are loosened, the distance between the first bearing beam 113 and the clamp assembly can be gradually increased, allowing the first insulator 14, the second bearing beam 121, and the second insulator 15 to be pulled away from the clamp assembly under the force of the lower guy wire. This relaxes the spring force supporting the second insulator 15, reducing the force at both ends of the second insulator 15, thus allowing the second insulator 15 to be removed and replaced. After replacement, simply adjust the long tie rod 30 to return the first bearing beam 113 to its original position and re-secure it. This device is flexible in structure, safe, and easy to operate. It allows for the replacement of barrel-shaped insulators at heights, saving significant time and ensuring both construction and broadcasting safety.

[0023] The clamp assembly can be fitted laterally onto the pull line. This fitted design creates a rotatable structure around the center of the pull line, restricting its radial displacement. Before the tool is fully installed, the pull line provides initial fixation, facilitating subsequent installation preparation. It offers stable support, streamlines installation, and reduces the number of personnel required for tool installation. The bottom of the long pull rod 30 can be equipped with a collar, hook, or other connecting structure. The first insulating frame 11 and the second insulating frame 12 have the same structure, both including a frame body 111. One end of the frame body 111 is connected to the pull line via a connector 13, and the other end includes two connecting rods 41. These connecting rods 41 are respectively connected to the two ends of the first bearing beam 113 or the second bearing beam 121. Both ends of the first bearing beam 113 and the second bearing beam 121 protrude beyond the connecting rods 41, and can be used to connect to the long pull rod 30.

[0024] As a specific implementation method, such as Figures 1-2 As shown, the clamp assembly includes two spaced-apart clamp bodies 21 and connectors. The connectors extend along the spacing direction and are detachably connected to the two clamp bodies 21. The connectors can be any detachable connector such as bolts, connecting pins, or other connecting parts. For example, the through holes of the clamp bodies 21 in the figure are correspondingly arranged, and bolts (not shown) can pass through the through holes and then be fixed with nuts. The arrangement of the two clamp bodies 21 and the connectors facilitates the installation of the clamp assembly, allowing it to be directly installed at the connector 13. Simultaneously, the connectors allow for adjustment of the spacing between the two clamp bodies 21 to accommodate pull cables of different diameters.

[0025] The drive unit can adopt any structure capable of linear drive, but since the medium-wave transmitting antenna insulation replacement tool of this application needs to meet the requirements of high-altitude operations, it is necessary to balance the product size and the generated driving force, such as... Figures 1-2 As shown, the drive unit includes a connecting frame and a jack 43. The connecting frame includes a connecting rod 41 and a support 42. One end of the connecting frame is connected to the support 42, and the other end is pivotally connected to the clamping plate assembly. The fixed end of the jack 43 is set on the support 42, and the movable end of the jack 43 is connected to one end of the long pull rod 30, which can push the long pull rod 30 closer to or away from the clamping plate assembly.

[0026] Specifically, the jack 43 can be a manual jack 43, which can be controlled by cranking the handle to move its movable end. It is easy to operate and has a small size, making it suitable for high-altitude operations. In the above structure, by extending the movable end of the jack 43, a force is generated that pulls the long tie rod 30 and the clamping plate assembly closer together; conversely, by extending the movable end of the jack 43, a force is generated that moves the long tie rod 30 and the clamping plate assembly away from each other.

[0027] To facilitate the installation of the long tie rod 30 at the predetermined position, such as Figures 1-2 As shown, the long tie rod 30 is rotatably connected to the movable end of the jack 43. This rotatable connection means that the ends of the long tie rod 30 furthest from the jack 43 can move away from or closer to each other, thus facilitating installation.

[0028] In addition, such as Figures 1-2 As shown, the long tie rod 30 is U-shaped, with its open end connected to the jack 43, and its bottom end able to be fitted onto the first bearing beam 113 or the second bearing beam 121. The U-shaped structure is simple and easy to implement.

[0029] In some embodiments, to further facilitate the replacement of the second insulator 15, such as Figures 1-2As shown, the first insulating frame 11 also includes a frame body 111 and a crossbeam 112. The insulation structure of the medium-wave transmitting antenna also includes a spring, which is disposed between the second insulator 15 and the crossbeam 112, and pushes the second insulator 15 to press against the second supporting beam 121. The medium-wave transmitting antenna insulation replacement tool also includes a spring fixing assembly 50, which is disposed on the crossbeam 112. The spring fixing assembly 50 includes a fixing ring 51, an adjusting rod 52, and a bracket 53. The bracket 53 is disposed on the side of the crossbeam 112 away from the spring. The fixing ring 51 can be sleeved and connected to the side of the spring away from the crossbeam 112. The adjusting rod 52 is connected to the bracket 53 and the fixing ring 51 respectively, and the adjusting rod 52 can drive the fixing ring 51 closer to the bracket 53. By using the fixing ring 51, the length of the spring is fixed so that it no longer abuts against the second insulator 15. When the second insulator 15 moves, a gap is created between the second insulator 15 and the spring, which facilitates disassembly.

[0030] To facilitate the installation and setting of the fixing ring 51, specifically, as follows: Figures 1-2 As shown, the fixing ring 51 is composed of two half-rings joined together.

[0031] In some embodiments, in order to adjust the position of the retaining ring 51 to match the position of the spring, the adjusting rod 52 includes an adjusting end with threads, which passes through the bracket 53 and is fitted with an adjusting nut.

[0032] In this embodiment, as Figures 1-2 As shown, the clamping plate body 21 is triangular, and its width is greater than that of the first insulating frame 11 and the second insulating frame 12. This arrangement allows the drive unit and the long pull rod 30 to extend into place from either side of the first insulating member or the second insulating frame 12, forming a straight line for easy tension under load.

[0033] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
