Description

Technical Field

[0001] This invention belongs to the technical field of insulator auxiliary tools, specifically relating to an insulator anti-derailment clamp for overhead insulated lines. Background Technology

[0002] Insulators are an indispensable core component in overhead insulated lines, primarily used for electrical insulation and mechanical fixation between conductors and towers. Their installation stability directly affects the safe operation of overhead lines. As the connection carrier between the insulator and the conductor, they must possess sufficient clamping force, anti-detachment performance, and adaptability to cope with complex operating conditions such as outdoor wind loads, icing, and vibration. Existing technologies mostly use aluminum wire locking structures. However, due to long-term exposure to line vibration and wind swaying, aluminum wire binding is prone to oxidation and loosening, leading to a decrease in clamping force. In extreme cases, this can cause the conductor to detach from the top of the insulator, resulting in line outages. Some existing methods replace aluminum wire with improved structures, thereby eliminating the defects of using aluminum wire binding.

[0003] Chinese patent CN118572595A discloses a device and method for preventing line insulator detachment. The device includes a first clamping arm, a second clamping arm, and an overhead conductor fixing assembly. These devices require multiple bolts to secure them to the insulator and the conductor, making installation cumbersome. Internally, they often use hinged or sliding connections, resulting in insufficient stability. Furthermore, the rigid connection between the device and the conductor exposes the conductor to long-term vibrations and wind swaying, easily damaging both the conductor and the device's structure, increasing future maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and solve the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-derailment clamp for an insulator used in overhead insulated lines, comprising a clamp body, the clamp body being sleeved on top of an insulator, the insulator being fixed to the upper side of a crossarm, a top block being provided on the top of the insulator, and a base plate being provided at the bottom of the clamp body, the base plate being connected to the top block via a positioning seat, the positioning seat comprising a cylinder, a positioning screw being rotatably provided on the side of the cylinder via a bearing, both ends of the positioning screw extending out of the cylinder being provided with internal hexagonal bolt heads, symmetrically movable grips being provided inside the cylinder, a straight rod being fixedly provided on the side of the grips near the positioning screw, both straight rods being screwed to the positioning screw via collars, a movable block being provided on the upper side of the base plate, a wire spool being provided above the movable block, a channel for the conductor to pass through being provided inside the wire spool, and a buffer mechanism being provided between the base plate and the movable block, the buffer mechanism being used to buffer the external force on the conductor.

[0006] The two grips are arc-shaped, and the internal threads of the two collars are in opposite directions. The arc-shaped grips facilitate contact with the surface of the wire, and the rotation of the positioning screw can cause the two collars to move closer or further apart.

[0007] The spool includes symmetrically arranged semi-rings, with one side of the two semi-rings hinged together and the other side fixed by bolts.

[0008] Both of the two semi-rings have clips inside, which are connected to the semi-rings via spring plates. The inner side of each clip has a pad. The pad provides protection for the conductor.

[0009] The buffer mechanism includes a translation groove and a translation block. The translation groove is located on the upper surface of the base plate. A long shaft is fixedly arranged inside the translation groove along the length direction. The translation block is located on the lower surface of the moving block. The long shaft passes through the middle of the translation block. A buffer spring is arranged between the end of the translation groove and the end of the translation block. The buffer spring is sleeved on the outside of the long shaft.

[0010] The translation groove is provided with a limiting groove on its side, and the translation block is engaged with the limiting groove by a limiting strip. The limiting strip and the limiting groove can prevent the translation block from coming out or shifting its position.

[0011] An anti-detachment mechanism is provided between the moving block and the bobbin. The anti-detachment mechanism includes a plug and a support arm. The bobbin is engaged with the moving block through the plug. The support arms are symmetrically arranged on the front and rear sides of the moving block. A vertical rod is provided at the end of the two support arms away from the moving block. A pressure ring is provided at the upper end of the vertical rod.

[0012] The moving block has a central groove on its upper surface, the insert block is inserted into the central groove, the moving block has symmetrical slots on its front and rear sides, the support arm is inserted into the slots, a linkage gear is provided in the middle of the central groove, and a slot is provided on the side of the linkage gear.

[0013] The insert block is symmetrically provided with internal racks on its sides, and the internal racks mesh with the linkage gears. The bottom of the insert block is engaged with the slot through an insert rod. The support arm is provided with an end block near the moving block, and an external rack is provided on the side of the end block, and the external rack meshes with the linkage gears.

[0014] The lower end of the upright is provided with a threaded section, which is screwed into the inside of the support arm. The height of the upright can be adjusted through the threaded section to maintain an appropriate distance between the pressure ring and the conductor.

[0015] This invention provides an insulator anti-derailment clamp for overhead insulated lines, which has the following advantages: The clamp body is connected to the top block of the insulator via a positioning seat. The rotation of the positioning screw in the positioning seat moves a straight rod screwed to it via a collar, thereby actuating the arc-shaped gripper and securing the top block firmly. This design is suitable for different types of insulators, effectively preventing the clamp body from detaching from the insulator and ensuring the safe and stable operation of the line.

[0016] A buffer mechanism is set between the base plate and the moving block. When the conductor is subjected to axial tension or shaking due to external forces such as wind, icing, or thermal expansion and contraction, the moving block drives the translation block to move along the long axis in the translation groove of the base plate. The buffer spring plays a buffering role between the end of the translation groove and the end of the translation block, which can absorb and disperse external forces, reduce the impact of external forces on the conductor, protect the conductor from damage, and extend the service life of the conductor.

[0017] The anti-detachment mechanism between the moving block and the spool employs a linkage gear design with an internal and external rack. The spool is inserted into the groove of the moving block via an insert block, and the insert rod at the bottom of the insert block engages with the slot of the linkage gear. When an external force causes the conductor to move upward and detach from the insulator, the linkage gear's linkage effect causes the upright at the end of the support arm and the pressure ring to press down against the outside of the conductor, achieving automatic locking of the spool installation. This prevents the spool from separating from the moving block due to external impact and prevents the conductor from detaching. Attached Figure Description

Detailed Implementation

[0029] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0030] Example 1 Please see Figures 1 to 6An anti-derailment clamp for overhead insulated lines includes a clamp body 2, which is sleeved on top of an insulator 1. The insulator 1 is fixed to the upper side of a crossarm 101. A top block 102 is provided on the top of the insulator 1, and a base plate 201 is provided on the bottom of the clamp body 2. The base plate 201 is connected to the top block 102 through a positioning seat 202. The positioning seat 202 includes a cylindrical body 2021. A positioning screw 2022 is rotatably provided on the side of the cylindrical body 2021 through a bearing. Both ends of the positioning screw 2022 extending out of the cylindrical body 2021 are provided with internal hexagonal bolts. The head 2023 has a gripping plate 2024 symmetrically and movably arranged inside the cylinder 2021. A straight rod 2025 is fixedly arranged on the side of the gripping plate 2024 near the positioning screw 2022. Both straight rods 2025 are screwed to the positioning screw 2022 through collars 2026. A moving block 203 is arranged on the upper side of the bottom plate 201. A wire spool 204 is arranged above the moving block 203. A channel for the wire 5 to pass through is arranged inside the wire spool 204. A buffer mechanism 3 is arranged between the bottom plate 201 and the moving block 203. The buffer mechanism 3 is used to buffer the external force on the wire 5.

[0031] Furthermore, the two grips 2024 are arc-shaped, and the two collars 2026 have opposite internal thread directions.

[0032] Furthermore, the spool 204 includes symmetrically arranged semi-rings 2041, with one side of the two semi-rings 2041 hinged together and the other side fixed by bolts 2042. The spool 204 adopts a symmetrical semi-ring 2041 structure with hinge and bolts 2042, which can be quickly opened and closed to facilitate the insertion and fixation of the wire 5.

[0033] Furthermore, each of the two semi-rings 2041 is provided with a clamping piece 2043. The clamping piece 2043 is connected to the semi-ring 2041 via a spring plate 2044, and a pad is provided on the inner side of the clamping piece 2043. The elastic force of the spring plate 2044 keeps the clamping piece 2043 tightly against the wire 5. Combined with the pad on the inner side of the clamping piece 2043, this increases the contact area with the wire 5, preventing excessive clamping force from damaging the wire insulation layer, and also counteracts slight radial movement of the wire, preventing the wire from loosening.

[0034] When using this device, confirm the specifications of the insulator 1, crossarm 101, and conductor 5 at the installation location to ensure that all components of the device are intact and undamaged, and that the moving parts operate smoothly.

[0035] Fit the clamp body 2 onto the insulator 1, aligning the bottom plate 201 of the clamp body 2 with the top block 102 of the insulator 1. Fit the cylinder 2021 of the positioning seat 202 onto the outside of the top block 102, ensuring that the top block 102 is positioned between the two arc-shaped grips 2024. Tighten the hexagonal head 2023 at either end of the positioning screw with an Allen wrench. When the positioning screw 2022 rotates, it will drive the two collars 2026 to move synchronously towards each other along the positioning screw 2022. This, in turn, will drive the two grips 2024 through the straight rod 2025 until they tightly clamp the top block 102, thus completing the positioning and fixing of the clamp body 2 and the insulator 1. After clamping, check that the clamp body 2 does not wobble or shift.

[0036] Open the spool half-ring 2041 by flipping it around the hinge point. Place the overhead insulated conductor 5 to be fixed between the clamps 2043 inside the two half-rings 2041, ensuring that the conductor 5 is in the central channel position of the spool 204. Close the two half-rings 2041, insert the bolt 2042 into the connecting hole of the half-ring 2041 and tighten it. During the closing process of the half-rings 2041, the internal spring plate 2044 is compressed and generates an elastic force, pushing the clamps 2043 to fit tightly against the conductor 5. The pad on the inner side of the clamps 2043 contacts the surface of the conductor 5, achieving flexible clamping of the conductor 5 and avoiding damage to the conductor insulation layer due to excessive clamping force. After tightening, check that the conductor has no radial loosening or slippage.

[0037] Example 2 Please see Figures 1 to 7 An anti-derailment clamp for overhead insulated lines includes a clamp body 2, which is sleeved on top of an insulator 1. The insulator 1 is fixed to the upper side of a crossarm 101. A top block 102 is provided on the top of the insulator 1, and a base plate 201 is provided on the bottom of the clamp body 2. The base plate 201 is connected to the top block 102 through a positioning seat 202. The positioning seat 202 includes a cylindrical body 2021. A positioning screw 2022 is rotatably provided on the side of the cylindrical body 2021 through a bearing. Both ends of the positioning screw 2022 extending out of the cylindrical body 2021 are provided with internal hexagonal bolts. The head 2023 has a gripping plate 2024 symmetrically and movably arranged inside the cylinder 2021. A straight rod 2025 is fixedly arranged on the side of the gripping plate 2024 near the positioning screw 2022. Both straight rods 2025 are screwed to the positioning screw 2022 through collars 2026. A moving block 203 is arranged on the upper side of the bottom plate 201. A wire spool 204 is arranged above the moving block 203. A channel for the wire 5 to pass through is arranged inside the wire spool 204. A buffer mechanism 3 is arranged between the bottom plate 201 and the moving block 203. The buffer mechanism 3 is used to buffer the external force on the wire 5.

[0038] Furthermore, the two grips 2024 are arc-shaped, and the two collars 2026 have opposite internal thread directions.

[0039] Furthermore, the spool 204 includes symmetrically arranged semi-rings 2041, with one side of the two semi-rings 2041 hinged together and the other side fixed by bolts 2042. The spool 204 adopts a symmetrical semi-ring 2041 structure with hinge and bolts 2042, which can be quickly opened and closed to facilitate the insertion and fixation of the wire 5.

[0040] Furthermore, each of the two semi-rings 2041 is provided with a clamping piece 2043. The clamping piece 2043 is connected to the semi-ring 2041 via a spring plate 2044, and a pad is provided on the inner side of the clamping piece 2043. The elastic force of the spring plate 2044 keeps the clamping piece 2043 tightly against the wire 5. Combined with the pad on the inner side of the clamping piece 2043, this increases the contact area with the wire 5, preventing excessive clamping force from damaging the wire insulation layer, and also counteracts slight radial movement of the wire, preventing the wire from loosening.

[0041] Furthermore, the buffer mechanism 3 includes a translation groove 301 and a translation block 302. The translation groove 301 is located on the upper surface of the base plate 201. A long shaft 3012 is fixedly arranged inside the translation groove 301 along the length direction. The translation block 302 is located on the lower surface of the moving block 203. The long shaft 3012 passes through the middle of the translation block 302. A buffer spring 303 is arranged between the end of the translation groove 301 and the end of the translation block 302. The buffer spring 303 is sleeved on the outside of the long shaft 3012.

[0042] Furthermore, a limiting groove 3011 is provided on the side of the translation groove 301, and the translation block 302 is engaged with the limiting groove 3011 through a limiting strip 3021. The engagement between the limiting groove 3011 and the limiting strip 3021 restricts the sliding direction of the translation block 302, prevents the moving block 203 from deflecting, and ensures the stability of the buffering effect.

[0043] In another embodiment, the buffer mechanism 3 is used to buffer the external force on the conductor 5 to prevent the conductor 5 from being damaged or broken due to the external force.

[0044] The buffer mechanism 3 forms an axial buffer structure through the translation groove 301, the long shaft 3012, the translation block 302, and the buffer spring 303 sleeved on the outside of the long shaft 3012. When the conductor 5 is subjected to external forces such as wind, icing, and thermal expansion and contraction of the conductor, which generate axial tension or sway, the moving block 203 can drive the translation block 302 to slide along the long shaft 3012. The buffer spring 303 absorbs the impact of external forces through compression and rebound, and offsets the axial displacement of the conductor 5. At the same time, the locking groove 3011 and the locking strip 3021 cooperate to restrict the sliding direction of the translation block 302, prevent the moving block 203 from deflecting, ensure the stability of the buffer effect, effectively reduce the pulling damage of external forces to the insulator 1, crossarm 101 and line connection parts, and improve the wind resistance and disaster resistance of the overhead line.

[0045] Example 3 Please see Figures 1 to 10 An anti-derailment clamp for overhead insulated lines includes a clamp body 2, which is sleeved on top of an insulator 1. The insulator 1 is fixed to the upper side of a crossarm 101. A top block 102 is provided on the top of the insulator 1, and a base plate 201 is provided on the bottom of the clamp body 2.

A positioning screw 2022 is rotatably provided on the side of the cylindrical body 2021 through a bearing. Both ends of the positioning screw 2022 extending out of the cylindrical body 2021 are provided with internal hexagonal bolts. The head 2023 has a gripping plate 2024 symmetrically and movably arranged inside the cylinder 2021. A straight rod 2025 is fixedly arranged on the side of the gripping plate 2024 near the positioning screw 2022. Both straight rods 2025 are screwed to the positioning screw 2022 through collars 2026. A moving block 203 is arranged on the upper side of the bottom plate 201. A wire spool 204 is arranged above the moving block 203. A channel for the wire 5 to pass through is arranged inside the wire spool 204. A buffer mechanism 3 is arranged between the bottom plate 201 and the moving block 203. The buffer mechanism 3 is used to buffer the external force on the wire 5.

[0046] Furthermore, the two grips 2024 are arc-shaped, and the two collars 2026 have opposite internal thread directions.

[0047] Furthermore, the spool 204 includes symmetrically arranged semi-rings 2041, with one side of the two semi-rings 2041 hinged together and the other side fixed by bolts 2042. The spool 204 adopts a symmetrical semi-ring 2041 structure with hinge and bolts 2042, which can be quickly opened and closed to facilitate the insertion and fixation of the wire 5.

[0048] Furthermore, each of the two semi-rings 2041 is provided with a clamping piece 2043. The clamping piece 2043 is connected to the semi-ring 2041 via a spring plate 2044, and a pad is provided on the inner side of the clamping piece 2043. The elastic force of the spring plate 2044 keeps the clamping piece 2043 tightly against the wire 5. Combined with the pad on the inner side of the clamping piece 2043, this increases the contact area with the wire 5, preventing excessive clamping force from damaging the wire insulation layer, and also counteracts slight radial movement of the wire, preventing the wire from loosening.

[0049] Furthermore, the buffer mechanism 3 includes a translation groove 301 and a translation block 302. The translation groove 301 is located on the upper surface of the base plate 201. A long shaft 3012 is fixedly arranged inside the translation groove 301 along the length direction. The translation block 302 is located on the lower surface of the moving block 203. The long shaft 3012 passes through the middle of the translation block 302. A buffer spring 303 is arranged between the end of the translation groove 301 and the end of the translation block 302. The buffer spring 303 is sleeved on the outside of the long shaft 3012.

[0050] Furthermore, a limiting groove 3011 is provided on the side of the translation groove 301, and the translation block 302 is engaged with the limiting groove 3011 through a limiting strip 3021. The engagement between the limiting groove 3011 and the limiting strip 3021 restricts the sliding direction of the translation block 302, prevents the moving block 203 from deflecting, and ensures the stability of the buffering effect.

[0051] Furthermore, an anti-detachment mechanism 4 is provided between the moving block 203 and the spool 204. The anti-detachment mechanism 4 includes an insert block 401 and a support arm 402. The spool 204 is engaged with the moving block 203 through the insert block 401. The support arm 402 is symmetrically arranged on the front and rear sides of the moving block 203. A vertical rod 404 is provided at one end of the two support arms 402 away from the moving block 203. A pressure ring 4041 is provided at the upper end of the vertical rod 404.

[0052] Furthermore, the upper surface of the moving block 203 is provided with a central groove 403, the insert block 401 is inserted into the central groove 403, the front and rear sides of the moving block 203 are symmetrically provided with outlet grooves 4032, the support arm 402 is inserted into the outlet groove 4032, the central groove 403 is provided with a linkage gear 4031 in the middle, and the linkage gear 4031 is provided with a slot 4033 on its side.

[0053] Furthermore, the insert block 401 is symmetrically provided with internal racks 4011 on its side, the internal racks 4011 mesh with the linkage gear 4031, the bottom of the insert block 401 is engaged with the slot 4033 through the insert rod 4012, the support arm 402 is provided with an end block 4021 near the moving block 203, the end block 4021 is provided with an external rack 4022 on its side, the external rack 4022 meshes with the linkage gear 4031.

[0054] Furthermore, the lower end of the upright 404 is provided with a threaded section 4042, which is screwed into the inside of the support arm 402.

[0055] In another embodiment, the anti-detachment mechanism 4 can prevent the conductor 5 from moving upward, thus preventing the conductor 5 from detaching from the insulator 1.

[0056] The anti-detachment mechanism 4 employs a linkage gear design with an inner rack 4011 and an outer rack 4022. When the spool 204 is inserted into the groove 403 of the moving block via the insert block 401, the insert rod 4012 at the bottom of the insert block 401 engages with the slot 4033. When the conductor 5 is subjected to external force and moves upward, the spool 204 drives the insert block 401 to move upward. The inner rack 4011 on the side of the insert block 401 drives the linkage gear 4031 to rotate, and the linkage gear 4031 drives the outer rack 4022 to move downward. This, in turn, drives the support arm 402 to move downward synchronously via the end block 4021. The two support arms 402 move synchronously, and the upright rod 404 at the end of the support arm 402 and the pressure ring 4041 press down and adhere to the conductor 5, preventing the conductor 5 from moving upward and avoiding the spool 204 from separating from the insulator 1 due to external impact. The threaded section 4042 at the lower end of the pole 404 is screwed to the support arm 402, and the pressing height of the pressure ring 4041 can be adjusted to adapt to different specifications of lines, ensuring the clamping effect. Moreover, the linkage structure requires no additional operation, and the anti-loosening locking is completed at the same time as the wire is installed, improving the installation efficiency and strengthening the protection effect.
