Description

Technical Field

[0001] The invention relates to the technical field of anti-vibration hammers, in particular to an anti-wear and anti-slip anti-vibration hammer. Background Art

[0002] The anti-vibration hammer is designed to reduce the vibration of the conductor caused by wind. The pole position of the high-voltage overhead line is high and the span is large. When the conductor is affected by wind, it will vibrate. When the conductor vibrates, the working conditions at the conductor suspension are the most unfavorable. Due to multiple vibrations, the conductor will suffer fatigue damage due to periodic bending. When the overhead line span is greater than 120 meters, anti-vibration hammers are generally used to prevent vibration.

[0003] When the existing anti-vibration hammer structure is in use, the wire clamp is usually directly clamped on the wire, or the wire is protected by aluminum tape or rubber pad. When directly clamped, the wire clamp is in direct contact with the wire, which is easy to wear the wire. When the wire is protected by aluminum tape or rubber pad, the gripping force of the wire clamp on the wire is less than that when directly clamped, which is more likely to cause slippage. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a wear-resistant and anti-skid anti-vibration hammer that adopts a wire protection structure and combines it with the protection structure of a threaded sleeve to achieve an anti-wear and anti-skid effect between the wire clamp assembly and the wire.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an anti-wear and anti-slip vibration-proof hammer, comprising a wire clamp assembly:

[0006] The wire clamp assembly comprises a wire clamp seat and a wire clamp cover, one end of the wire clamp seat and the wire clamp cover are rotatably connected by a pin shaft, and the other end is connected by a fastening assembly;

[0007] A wire cavity is formed between the wire clamp seat and the wire clamp cover, and the inner wall of the wire cavity is provided with a pre-twisted protective wire, and the pre-twisted protective wire is wound around the outer wall of the conductor;

[0008] The inner walls at both ends of the wire clamp seat and the wire clamp cover are each provided with a threaded sleeve that moves along the length direction of the wire;

[0009] A stranded wire seat is arranged at the bottom of the wire clamp assembly, and a steel stranded wire is passed through the stranded wire seat, and anti-vibration hammer heads are arranged at both ends of the steel stranded wire.

[0010] As a further description of the above technical solution:

[0011] The threaded sleeve comprises a threaded sub-sleeve and a threaded female sleeve which are adapted and correspondingly clamped. After the threaded sub-sleeve and the threaded female sleeve are clamped, they are screwed to the threaded grooves provided on the inner walls of the wire clamp seat and the wire clamp cover.

[0012] As a further description of the above technical solution:

[0013] Also included is a containment kit;

[0014] The sealed kit comprises a sealed sub-sleeve and a sealed female sleeve which are adapted and correspondingly snap-fitted. After the sealed sub-sleeve and the sealed female sleeve are snap-fitted, they are connected to the recessed parts provided on the inner walls of the wire clamp seat and the wire clamp cover.

[0015] As a further description of the above technical solution:

[0016] The fastening assembly includes a fastening bolt, one end of which extends into the wire clamp seat and is connected to the embedded nut, and the other end of which extends to the outside of the wire clamp cover and is connected to the external nut.

[0023] As a further description of the above technical solution:

[0024] The length of the pressing tube is consistent with the depth of the pressing groove, and a rotating handle is arranged on the outer wall of the pressing tube.

[0025] The present invention provides an anti-wear and anti-slip anti-vibration hammer. It has the following beneficial effects:

[0026] (1) The anti-vibration hammer protects the conductor by installing a pre-twisted protective strip, which can prevent the wire clamp assembly from squeezing and wearing the wire, greatly improving the safety performance while meeting the gripping force requirements of the wire clamp.

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, an anti-wear and anti-slip anti-vibration hammer includes a wire clamp assembly 1:

[0038] The wire clamp assembly 1 includes a wire clamp seat 11 and a wire clamp cover 13. One end of the wire clamp seat 11 and the wire clamp cover 13 are rotatably connected by a pin shaft 12, and the other end is connected by a fastening assembly 2. The wire clamp seat 11 and the wire clamp cover 13 are both made of high-strength ZL101A aluminum alloy after low-pressure die casting and T6 heat treatment.

[0039] A wire cavity 7 is formed between the wire clamp seat 11 and the wire clamp cover 13, and the inner wall of the wire cavity 7 is provided with a pre-twisted protective wire 6, and the pre-twisted protective wire 6 is wound around the outer wall of the conductor. The pre-twisted protective wire 6 is a spiral structure, and is made of materials such as aluminum-clad steel wire or high-strength aluminum alloy wire according to the use conditions. The end portion adopts an arc design and is anti-corrosion treated to effectively prevent corrosion and corona generation;

[0040] The inner walls of both ends of the wire clamp seat 11 and the wire clamp cover 13 are provided with a threaded sleeve 16 that moves along the length direction of the wire;

[0041] A stranded wire seat 3 is provided at the bottom of the wire clamp assembly 1, and a steel stranded wire 4 is penetrated through the stranded wire seat 3, and anti-vibration hammer heads 5 are provided at both ends of the steel stranded wire 4. The anti-vibration hammer heads 5 can be manufactured in different wire diameters and hammer head forms according to the usage status, such as a tuning fork hammer head or a torsion hammer head.

[0042] In this embodiment, the pre-twisted protective strip 6 is spirally wound around the outer wall of the conductor, and the wire clamp seat 11 and the wire clamp cover 13 are sleeved on the outer wall of the conductor, and the wire clamp cover 13 is rotated to close it with the wire clamp seat 11 under the action of the pin shaft 12, and the fastening action of the fastening component 2 is used to achieve the fastening connection between the wire clamp seat 11 and the wire clamp cover 13, which can prevent the wire clamp assembly 1 from squeezing and wearing the wire, greatly improve the safety performance, and meet the gripping force requirements of the wire clamp assembly 1, ensuring that the wire and the protective strip will not escape from the clamping area from the opening direction of the wire clamp, thereby preventing loosening. At the same time, combined with the set threaded sleeve 16, it can play a secondary closed protection role at the end of the wire clamp assembly 1, and further play a closed protection effect between the wire clamp assembly 1, the pre-twisted protective strip 6 and the wire, thereby ensuring the stability of the gripping force of the wire clamp assembly 1 as much as possible, and achieving the anti-vibration hammer anti-wear and anti-slip effects.

[0043] like Figure 4 and Figure 5 As shown, the threaded sleeve 16 includes a threaded sub-sleeve 161 and a threaded female sleeve 162 that are adapted and correspondingly clamped. After the threaded sub-sleeve 161 and the threaded female sleeve 162 are clamped, they are screwed into the threaded groove 15 opened on the inner wall of the wire clamp seat 11 and the wire clamp cover 13, so that the threaded sub-sleeve 161 and the threaded female sleeve 162 can be correspondingly clamped from both sides of the wire respectively, and screwed into the threaded groove 15, which can play a secondary reinforcement role for the wire, the wire clamp assembly 1 and the pre-twisted wire protection line 6.

[0044] like Figure 4 and Figure 5As shown, it also includes a sealed kit 17, which includes a sealed sub-sleeve 171 and a sealed mother sleeve 172 that are adapted and correspondingly snap-fitted. After the sealed sub-sleeve 171 and the sealed mother sleeve 172 are snap-fitted, they are connected to the recessed portion 18 opened on the inner wall of the wire clamp seat 11 and the wire clamp cover 13. The sealed sub-sleeve 171 and the sealed mother sleeve 172 are respectively snap-fitted from both sides of the wire and embedded in the recessed portion 18, which can play a role of sealed protection for the threaded kit 16 and prevent dust and impurities from entering the wire clamp assembly 1 and causing pollution.

[0045] like Figure 2 As shown, the fastening assembly 2 includes a fastening bolt 22, one end of the fastening bolt 22 extends into the wire clamp seat 11 and is connected to the embedded nut 21, and the other end extends to the outside of the wire clamp cover 13 and is connected to the external nut 23. The use of the inner and outer synchronous connection method of the two nuts can effectively ensure the long-term safe operation of the anti-vibration hammer and ensure that the fastening bolt 22 is tightened as before without any looseness.

[0046] like Figure 3 As shown, the inner wall of the wire cavity 7 formed by the wire clamp seat 11 and the wire clamp cover 13 is provided with a plurality of convex tooth blocks 14, and the inclination directions of the plurality of convex tooth blocks 14 are the same, which can increase the friction force on the pre-twisted protective wire 6, increase the gripping force of the wire clamp assembly 1 on the pre-twisted protective wire 6, and avoid the wire clamp assembly 1 from loosening.

[0047] like Figure 6 As shown, a preset hole 52 is provided on the anti-vibration hammer head 5, and a sleeve 51 is embedded in the inner wall of the preset hole 52, and the sleeve 51 is located on the outer wall of the steel strand 4, which can play a flexible protection role for the end of the steel strand 4 inserted into the preset hole 52, avoiding the generation of a connection gap between the steel strand 4 and the preset hole 52.

[0048] like Figure 6 As shown, the inner wall of the preset hole 52 is provided with a pressing groove 55, and the inner wall of the pressing groove 55 is provided with a pressing tube 53, and the pressing tube 53 is located on the outer wall of the sheath 51. By embedding the pressing tube 53 into the pressing groove 55, the pressing tube 53 generates an inward squeezing force on the sheath 51, and makes the sheath 51 tightly attached to the steel strand 4, thereby greatly improving the connection stability between the steel strand 4 and the anti-vibration hammer head 5.

[0049] like Figure 6 As shown, the length of the pressing tube 53 is consistent with the depth of the pressing groove 55, ensuring that the pressing tube 53 is embedded in a hidden state. The outer wall of the pressing tube 53 is provided with a rotating handle 54 to facilitate the disassembly and assembly of the pressing tube 53.
