Description

Technical Field

[0001] The present invention relates to the technical field of electric tools, and particularly relates to a prestressed anti-wear and anti-vibration hammer. Background Art

[0002] An overhead transmission line is located above the ground. The conductor vibrates under the action of external wind force. If the vibration is out of range for a long time, the connection between the conductor and the tower pole will be worn due to friction and may break. To prevent the occurrence of the above problems, the current common practice in the industry is to install anti-vibration fittings on the conductor to eliminate or reduce the vibration of the conductor caused by wind force and reduce it to within the allowable limit.

[0003] Anti-vibration fittings are divided into bolt type and prestressed type. Since the prestressed anti-vibration hammer is easy to install and has good anti-vibration effect, it is widely used in the market. The prestressed anti-vibration hammer is hooked on the conductor through a clamp. The inner arc surface of the clamp contacts the conductor, and the prestressed wire is wound to prevent the movement of the clamp. The prestressed wire is clamped on the outer side surface of the clamp. However, there are many disadvantages in the current clamps on the market. For example, the jumping contact is prone to slippage, which affects the anti-vibration effect. The contact between the conductor and the clamp is point contact, which is easy to accelerate the wear of the conductor. In addition, during the operation of the transmission line, the prestressed anti-vibration hammer sometimes has relative frictional movement between the clamp and the ground wire due to insufficient grip of the prestressed wire. Over time, it will cause the clamp of the anti-vibration hammer to wear the ground wire, eventually causing fatigue and broken strands of the ground wire and triggering line accidents.

[0004] In order to solve the deficiencies of the existing technology, people have carried out long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a hook-type prestressed anti-vibration hammer [CN202010293734.9], which includes a hook part, a connecting part, and a sleeve part. The hook part is a semi-ellipsoid with both left and right ends cut into planes, and the semi-circular groove of the hook part is internally tangent to the conductor and is surface contact, which solves the problems of large concentrated stress caused by point contact or short line contact and wire wear, thus ensuring the normal operation of the transmission line and the service life of the conductor. At the same time, the middle of the upper arc surface of the hook part is thick and gradually thins towards both ends. The side surface of the prestressed wire is tangent to the upper arc surface and is line contact, which solves the problem of the clamp sliding along the axial direction of the conductor caused by jumping point contact, thus ensuring that the hook part cannot move along the circumferential direction and the axial direction of the conductor, making the anti-vibration hammer not only have good anti-vibration effect, but also ensure the service life and normal operation of the transmission line.

[0005] The above - mentioned solution solves to a certain extent the problems in the prior art that the pre - formed vibration - damping hammer is prone to slippage due to jumping contact and point contact is prone to accelerating the wear of the conductor. However, there are still many deficiencies in this solution. For example, insufficient grip of the pre - formed wire is likely to cause relative frictional movement between the clamp and the conductor - ground wire, resulting in wear of the vibration - damping hammer clamp on the conductor - ground wire, ultimately causing fatigue and strand breakage of the conductor - ground wire and triggering line accidents.

Specific embodiments

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] As Figures 1-11 shown, a pre-twisted anti-wear and anti-vibration hammer includes a line clamp body 1. The upper end of the line clamp body 1 is movably and rotatably connected to a line clamp cover plate 2 through a hinge pin shaft 11. An annular clamping channel 3 is formed between the line clamp body 1 and the line clamp cover plate 2. A tightening and pressing structure 4 extending into the annular clamping channel 3 is provided through the line clamp body 1 and the line clamp cover plate 2. And a plug-in connection assembly 5 is provided on the circumferential inner side of the annular clamping channel 3 between the line clamp body 1 and the line clamp cover plate 2. The line clamp body 1 and the line clamp cover plate 2 are connected by a ball joint bolt structure 6 on the lower side of the annular clamping channel 3. And a movable positioning mechanism 7 for rotationally positioning the ball joint bolt structure 6 is provided through the line clamp body 1.

[0032] Among them, the upper end of the clamp body 1 is provided with a hinge groove 12, the upper end of the clamp cover plate 2 is provided with a hinge portion 21 inserted into the hinge groove 12, and the hinge pin shaft 11 passes through the hinge groove 12 and the hinge portion 21 to form rotational positioning of the clamp cover plate 2.

[0033] The clamp body 1 and the clamp cover plate 2 are rotatably connected by a hinge pin shaft 11, and the rotation range thereof is between 0 and 90 degrees.

[0034] Obviously, the tightening and pressing structure 4 includes a pressing and clamping portion 41 provided on the inner wall of the annular clamping channel 3. The inner surface of the pressing and clamping portion 41 is provided with a flexible fitting portion 42, and the outer surface of the pressing and clamping portion 41 is connected with a tightening cover body 44 through a tightening screw 43. Threaded channels 45 through which the corresponding tightening screws 43 can pass are provided on the clamp body 1 and the clamp cover plate 2, and a positioning groove hole 46 is provided on the upper end surface of the threaded channel 45. A limiting spring 47 sleeved on the circumferential outer side of the tightening screw 43 is provided between the positioning groove hole 46 and the tightening cover body 44, and a rubber wear-resistant portion 48 is provided between the outer wall of the pressing and clamping portion 41 and the tightening screw 43. The diameter of the rubber wear-resistant portion 48 is larger than the diameter of the threaded channel 45.

[0035] According to the diameter specification of the ground wire, the tightening screw 43 is adjusted to make the flexible fitting portion 42 closely fit the outer wall of the ground wire. And the inside of the tightening cover body 44 is hollow and is used for positioning the limiting spring 47. Secondly, the tightening cover body 44 is also used for rotational limiting of the clamp cover plate 2.

[0036] It can be seen that a plurality of flexible auxiliary clamping portions 49 are provided on the inner wall of the annular clamping channel 3 and on one side of the pressing and clamping portion 41.

[0037] The flexible auxiliary clamping portion 49 is an elastic portion for assisting in pressing the ground wire to avoid rigid contact between the ground wire and the inner walls of the clamp body 1 and the clamp cover plate 2.

[0038] Specifically, the plug-in connection assembly 5 includes an arc-shaped plug-in portion 51 provided on the inner wall of the clamp cover plate 2. A plug-in connection seat 52 corresponding to the arc-shaped plug-in portion 51 is provided on the inner wall of the clamp body 1. A plug-in cavity 521 is provided on the circumferential inner side of the plug-in connection seat 52. A transverse pressing rod 522 is provided in the plug-in cavity 521, and a lifting stroke groove 523 for the transverse pressing rod 522 to lift and lower is provided on the inner wall of the plug-in cavity 521. A longitudinal pressing rod 524 perpendicular to the transverse pressing rod 522 is provided at the upper end of the transverse pressing rod 522. One end of the longitudinal pressing rod 524 far from the transverse pressing rod 522 extends out of the plug-in connection seat 52 and a pressing portion 525 is provided at the upper end. A top pressure spring 526 is provided on the circumferential outer side of the longitudinal pressing rod 524 between the pressing portion 525 and the plug-in connection seat 52. A flexible compressive material is filled in the hollow hole 527 on the inner wall of the pressing portion 525.

[0039] More specifically, an open plugging groove 511 is provided on the inner wall of the arc-shaped plugging portion 51. A number of pressing rod positioning grooves 512 corresponding to the transverse pressing rod 522 are provided on the inner wall of the open plugging groove 511. A plugging relief groove 513 corresponding to the longitudinal pressing rod 524 is provided on the arc-shaped plugging portion 51. When the arc-shaped plugging portion 51 is inserted into the plugging cavity 521 of the plugging connection base 52, the transverse pressing rod 522 is positioned in the pressing rod positioning groove 512 and the longitudinal pressing rod 524 is located in the plugging relief groove 513. The pressing portion 525 is stressed to press and position the transverse pressing rod 522.

[0040] After the ground wire is inserted, the wire clamp cover plate 2 is rotated, and one end of the arc-shaped plugging portion 51 is directly inserted into the plugging cavity 521. The transverse pressing rod 522 is clamped into the pressing rod positioning groove 512. Since the ground wire forms a top pressure on the pressing portion 525, the top pressure acting force is transmitted to the transverse pressing rod 522, so that the transverse pressing rod 522 is pressed tightly in the pressing rod positioning groove 512, finally realizing adaptive locking according to the specification of the ground wire. And when the ground wire is disturbed by a strong wind environment, it can always maintain an elastic pressing and fitting state, improving the pressing toughness.

[0041] Furthermore, the annular clamping channel 3 is composed of annular halves respectively arranged on the inner walls of the wire clamp body 1 and the wire clamp cover plate 2. The lower ends of the wire clamp body 1 and the wire clamp cover plate 2 are respectively provided with a cover plate extension portion 22 and a body extension portion 13. The swivel bolt structure 6 forms a connection and positioning for the cover plate extension portion 22 and the body extension portion 13. A relief connection through groove 14 is provided on the body extension portion 13.

[0042] Even further, the swivel bolt structure 6 includes a locking bolt 61 for connecting the cover plate extension portion 22 and the body extension portion 13. One end of the locking bolt 61 and on the outer wall of the cover plate extension portion 22 is provided with a first annular thread groove 62. And one end of the first annular thread groove 62 is provided with a second annular thread groove 63. A limit nut 64 for positioning and connecting the cover plate extension portion 22 is provided on the first annular thread groove 62. A positioning nut 65 for limiting the limit nut 64 is provided on the second annular thread groove 63.

[0043] The double-nut progressive method is used for locking, and the first annular thread groove 62 and the second annular thread groove 63 are provided to ensure the locking effect of the limit nut 64 and the positioning nut 65, avoiding the situation of thread slipping.

[0044] Specifically, a rubber isolation sleeve 66 is provided on the locking bolt 61. A number of guiding sliding rails 67 for the rubber isolation sleeve 66 to slide are provided on the outer wall of the locking bolt 61. A number of guiding sliding grooves 68 corresponding to the guiding sliding rails 67 one by one are provided on the circumferential inner side of the rubber isolation sleeve 66. An annular connection groove 69 for the rubber isolation sleeve 66 to insert is provided inside the connecting cover plate extension portion 22.

[0045] The rubber isolation sleeve 66 is used to prevent the cover extension 22 from contacting the main body extension 13, and the locking condition of the limit nut 64 can be adjusted as needed, so that the wire clamp cover 2 has rotation margin in a strong wind environment.

[0046] Preferably, the movable positioning mechanism 7 includes a rotating ball head 71 arranged at one end of the locking bolt 61, and the rotating ball head 71 is rotated and positioned in the easing connection groove 14 by inserting the positioning link 72, and the inserting positioning link 72 includes a positioning insert 721, and the positioning insert 721 has a positioning link 722 inserted therein, and the ends of the positioning insert 721 and the positioning link 722 that are away from each other are positioned on the outer walls of both sides of the main body extension part 13, and the positioning link 722 is provided with a telescopic positioning rod 723, and the positioning insert 721 is provided with an arc-shaped movable hole 724 for the telescopic positioning rod 723 to pass through, and the rotating ball head 71 is provided with a travel limit through hole 725 for the telescopic positioning rod 723 to pass through and is arranged corresponding to the arc-shaped movable hole 724.

[0047] The function of the movable positioning mechanism 7 is to provide a rotation margin for the rotation of the wire clamp body 1 and to maintain the same connection force when the body extension 13 rotates, thereby ensuring the connection strength between the body extension 13 and the cover extension 22 .

[0048] In summary, the principle of this embodiment is that after the ground wire passes through the annular clamping channel 3, the wire clamp cover plate 2 is rotated, one end of the arc-shaped plug-in portion 51 is directly inserted into the plug-in cavity 521, and the transverse pressure rod 522 is stuck in the pressure rod positioning groove 512. At this time, according to the specifications, clamping requirements and clamping margin requirements of the ground wire, the tightening screw 43 is rotated to make the clamping portion 41 clamp the ground wire. At this time, the ground wire forms a top pressure on the crimping portion 525, and its top pressure force is transmitted to the transverse pressure rod 522, so that the transverse pressure rod 522 is pressed in the pressure rod positioning groove 512, and finally the ground wire is clamped according to the specifications, clamping requirements and clamping margin requirements. The specification of the wire is adaptively locked and elastic compression margin is provided; secondly, the main extension part 13 and the cover extension part 22 are connected by the locking bolt 61, and the limit position of the limit nut 64 is adjusted. The wire clamp cover plate 2 has a rotation margin in a strong wind environment, and the rotating ball head 71 and the main extension part 13 are connected by plugging the positioning link 72. The telescopic positioning rod 723 automatically pops out when passing through the arc-shaped movable hole 724 and passes through the travel limit through hole 725, thereby providing a rotation margin for the rotation of the wire clamp body 1 and ensuring the connection strength between the main extension part 13 and the cover extension part 22. While the ground wire is tightly pressed, compression toughness is provided, and rotation margin is provided for the connection between the wire clamp body 1 and the wire clamp cover plate 2, so that the ground wire and the wire clamp body 1 and the wire clamp cover plate 2 can maintain sufficient activity toughness in a strong wind environment, and ensure the compression strength of the wire, avoid excessive relative movement to cause wear and damage caused by excessive rigid compression force due to wind force.
