Description

Technical Field

[0001] The invention relates to the technical field of electric tools, and in particular to a pre-twisted anti-wear and anti-vibration hammer. Background Art

[0002] Overhead transmission lines are located above the ground, and the conductors vibrate under the influence of external wind. If they are in excessive vibration for a long time, the connection between the conductor and the tower pole will break due to friction. In order to prevent the above problems from happening, the more common practice in the industry is to install anti-vibration hardware on the conductors to eliminate or reduce the vibration of the conductors caused by wind to within the allowable limit.

[0003] Anti-vibration hardware is divided into bolt type and pre-twisted type. The pre-twisted anti-vibration hammer is widely used in the market because it is easy to install and has good anti-vibration effect. The pre-twisted anti-vibration hammer is hung on the conductor through the wire clamp hook. The inner arc surface of the wire clamp contacts the conductor. The pre-twisted wire is wound to prevent the movement of the wire clamp. The pre-twisted wire clamp is on the outer surface of the wire clamp. However, there are many disadvantages in the wire clamps on the market. For example, the jumping contact is prone to slippage, which affects the anti-vibration effect. The contact between the wire and the wire clamp is point contact, which is easy to accelerate the wear of the wire. In addition, the pre-twisted anti-vibration hammer often has relative friction between the wire clamp and the ground wire during the operation of the transmission line due to insufficient grip of the pre-twisted wire. As time accumulates, the anti-vibration hammer wire clamp will wear the ground wire, and eventually cause fatigue breakage of the ground wire, causing line accidents.

[0004] In order to solve the deficiencies of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a hook-type pre-twisted anti-vibration hammer [CN202010293734.9], which includes a hook part, a connecting part, and a sleeve part. The hook part is a semi-ellipsoidal shape with the left and right ends cut into planes, and the semicircular groove of the hook part is inscribed with the conductor and is in surface contact, which solves the problem of large concentrated stress caused by point contact or short line contact and causing conductor wear, thereby ensuring the normal operation of the transmission line and the service life of the conductor. At the same time, the upper arc surface of the hook part is thick in the middle and gradually becomes thinner towards the two ends. The side of the pre-twisted wire is tangent to the upper arc surface and is in line contact, which solves the problem of the wire clamp sliding along the axis of the conductor caused by jumping point contact, thereby ensuring that the hook part cannot move along the circumference and axis of the conductor, so that the anti-vibration hammer not only has a good anti-vibration effect, but also ensures the service life and normal operation of the transmission line.

[0005] The above scheme has solved to a certain extent the problem in the prior art that the pre-twisted anti-vibration hammer jumping contact is prone to slippage and the point contact is prone to accelerate the wear of the wire. However, the scheme still has many shortcomings. For example, insufficient grip of the pre-twisted wire can easily lead to relative friction movement between the wire clamp and the ground wire, causing the anti-vibration hammer wire clamp to wear the ground wire, and ultimately causing fatigue breakage of the ground wire, leading to line accidents.

The tightening cover body 44 here is hollow and positioned with the limit spring 47. Secondly, the tightening cover body 44 is also used to limit the rotation of the wire clamp cover plate 2.

[0025] 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 clamping portion 41 .

[0026] The flexible auxiliary clamping portion 49 is an elastic portion, which is used to assist in compressing the ground wire to avoid rigid contact between the ground wire and the inner wall of the wire clamp body 1 and the wire clamp cover plate 2 .

[0027] Specifically, the plug-in connection component 5 includes an arc-shaped plug-in portion 51 arranged on the inner wall of the wire clamp cover plate 2, and a plug-in connection seat 52 arranged corresponding to the arc-shaped plug-in portion 51 is arranged on the inner wall of the wire clamp body 1. A plug-in cavity 521 is arranged on the inner side of the plug-in connection seat 52. A transverse pressure rod 522 is arranged in the plug-in cavity 521, and a lifting stroke groove 523 for the transverse pressure rod 522 to be lifted and lowered is arranged on the inner wall of the plug-in cavity 521.

[0028] More specifically, an open plug-in groove 511 is provided on the inner wall of the arc-shaped plug-in portion 51, and a plurality of pressure rod positioning grooves 512 are provided on the inner wall of the open plug-in groove 511 corresponding to the transverse pressure rod 522. A plug-in clearance groove 513 is provided on the arc-shaped plug-in portion 51 corresponding to the longitudinal pressure rod 524.

Since the ground wire forms a top pressure on the crimping portion 525, its top pressure force is transmitted to the transverse pressure rod 522, so that the transverse pressure rod 522 is pressed tightly in the pressure rod positioning groove 512, and finally adaptive locking is achieved according to the specifications of the ground wire. When the ground wire is disturbed by a strong wind environment, it can always include an elastic compression and fitting state, thereby improving the compression toughness.

[0030] 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, and the lower ends of the wire clamp body 1 and the wire clamp cover plate 2 are respectively provided with a cover extension 22 and a main body extension 13, and the movable bolt structure 6 forms a connection and positioning between the cover extension 22 and the main body extension 13, and the main body extension 13 is provided with a make-way connecting groove 14.

[0031] Furthermore, the movable bolt structure 6 includes a locking bolt 61 for connecting the cover extension 22 and the main body extension 13, a first annular thread groove 62 is provided at one end of the locking bolt 61 and located on the outer wall of the cover extension 22, and a second annular thread groove 63 is provided at one end of the first annular thread groove 62, a limiting nut 64 for positioning the connection cover extension 22 is provided on the first annular thread groove 62, and a positioning nut 65 for limiting the limiting nut 64 is provided on the second annular thread groove 63.

[0032] Double nuts are used for locking in a progressive manner, and a first annular thread groove 62 and a second annular thread groove 63 are provided to ensure the locking effect of the limit nut 64 and the positioning nut 65 to avoid thread slippage.

[0034] 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.

[0035] 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.

[0036] 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 .

[0037] 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.
