Description

Technical Field

[0001] The utility model relates to the technical field of anti-vibration hammers, in particular to an anti-vibration hammer for high-voltage power transmission lines. Background Art

[0002] High-voltage transmission lines are usually subject to vibrations caused by various external factors such as wind and climate, and the anti-vibration hammer can absorb or suppress these vibrations, reduce the vibration amplitude, reduce the vibration frequency of the line, prevent failures caused by vibration, improve the safety of the line, and ensure stable operation of the line. The anti-vibration hammer in the prior art can effectively prevent vibration of the high-voltage transmission line, but bolts and nuts are used to clamp the high-voltage transmission line during installation, and the bolts and nuts are loose when used together.

[0003] A Chinese patent discloses an anti-vibration hammer for high-voltage transmission lines (authorization announcement number CN104753011B). The patented technology includes a wire clamp, a steel strand and a hammer head. The wire clamp is fixedly connected to the high-voltage line, the lower end of the wire clamp is connected to the steel strand, and the two ends of the steel strand are fixedly connected to two hammer heads symmetrical to the wire clamp. The hammer head is provided with a hollow cavity, and mercury is enclosed in the hollow cavity. The two hammer heads on both sides of the wire clamp are the same. The present invention is easy to implement and has a significant improvement in the effect of the anti-vibration hammer for high-voltage transmission lines.

[0004] This patented technology has a good anti-vibration effect on high-voltage transmission lines when in use, but there are still some shortcomings during use. No improvement is made to the connection of the high-voltage transmission lines, and bolts and nuts are still used to clamp and fix the high-voltage wires. The bolts are loose, resulting in instability of the anti-vibration hammer and loss of the anti-vibration effect on the high-voltage transmission lines. Therefore, those skilled in the art provide an anti-vibration hammer for high-voltage transmission lines to solve the problems raised in the above background technology. Utility Model Content

[0005] 1. Technical solution

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model is an anti-vibration hammer for high-voltage power transmission lines, comprising an anti-vibration hammer body;

[0008] The mounting structure includes a ferrule located at the upper end of the anti-vibration hammer body, a screw hole opened inside the upper end of the ferrule, a screw rod rotatably inserted into the screw hole, a mounting column located at the lower end of the screw rod, and a clamping plate located below the mounting column;

[0009] as well as;

[0010] The anti-loosening structure includes a support plate located on one side of the mounting column and connected to the inner wall of the upper end of the ferrule, a bearing embedded in the inner wall of the upper end of the ferrule, a rotating shaft rotatably inserted into the bearing, a clamping block located at one end of the rotating shaft, a limit block located on the inner wall of one side of the support plate, a torsion spring sleeved on the outside of the rotating shaft and with the upper and lower ends respectively connected to the inner wall of the ferrule and the outer wall of the clamping block, and a clamping groove arranged in a circular array on the outer wall of the mounting column.

[0011] Furthermore, a rubber pad is provided at the lower end of the card plate, and an insulating pad is provided on the inner wall of the card sleeve;

[0012] Specifically, the rubber pad allows the card plate to be in flexible contact with the high-voltage transmission line, the outer wall of the high-voltage transmission line is protected, and the high-voltage transmission line and the installation structure are effectively insulated and installed through the insulating pad.

[0013] Furthermore, a rotating seat is embedded and installed inside the upper end of the card plate, and the lower end of the mounting column is rotatably mounted inside the rotating seat;

[0014] Specifically, when the rotating force of the screw drives the installation column to rotate, the rotating force of the installation column acts on the inside of the rotating seat through the rotating seat, preventing the clamping block from rotating synchronously with the installation column, so that the clamping block can stably clamp the high-voltage transmission line.

[0015] Furthermore, a mounting opening is provided at one end of the ferrule, and the mounting opening is located at one side of the ferrule;

[0016] Specifically, the high-voltage transmission line is placed inside the ferrule through the installation opening.

[0017] Furthermore, the outer wall of the screw is provided with rotating rods distributed in a ring array;

[0018] Specifically, when rotating the screw, the worker can apply a rotational force to the screw by grasping the rotating rod.

[0019] Furthermore, a rotating block is provided at one end of the rotating shaft, and one end of the rotating block is in contact with the outer wall of the limiting block;

[0020] Specifically, the rotating block rotates along with the rotating shaft, and when the rotating block rotates toward the limiting block, the rotating block is intercepted by the limiting block.

[0021] 2. Beneficial effects

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] The utility model sleeves the high-voltage cable through the clamping sleeve, and the screw rod cooperates with the screw hole. When the screw rod rotates inside the screw hole, the clamping plate is driven to move longitudinally to clamp the high-voltage power transmission line, so that the high-voltage power transmission line is clamped and fixed;

[0024] At the same time, when the screw rotates, it drives the mounting column to rotate. When the mounting column rotates, it squeezes the elastic supporting block. After the block corresponds to the slot inside the mounting column, the block is limited by the limit block to avoid reverse rotation of the block and loosening of the fixing part. The stability of the anti-vibration hammer is improved during use, and stable vibration reduction is performed on the high-voltage transmission line.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example 1

[0041] See also Figure 1-Figure 5 As shown, this embodiment is a vibration-proof hammer for a high-voltage transmission line, comprising a vibration-proof hammer body 100;

[0042] The mounting structure 200 includes a sleeve 207 located at the upper end of the anti-vibration hammer body 100, a screw hole 209 opened inside the upper end of the sleeve 207, a screw rod 202 rotatably inserted into the screw hole 209, a mounting post 203 located at the lower end of the screw rod 202, and a clamping plate 204 located below the mounting post 203;

[0043] A rubber pad 206 is provided at the lower end of the card plate 204, and an insulating pad is provided on the inner wall of the card sleeve 207;

[0044] A rotating seat 205 is embedded in the upper end of the clamping plate 204, and the lower end of the mounting column 203 is rotatably mounted inside the rotating seat 205;

[0045] An installation opening 208 is provided at one end of the ferrule 207, and the installation opening 208 is located at one side of the ferrule 207;

[0046] The outer wall of the screw 202 is provided with rotating rods 201 distributed in a circular array;

[0047] Performing use of the mounting structure 200;

[0048] When the sleeve 207 is sleeved on the outer wall of the high-voltage transmission line, the installation port 208 corresponds to the high-voltage transmission line, and the sleeve 207 is sleeved on the outside of the high-voltage transmission line through the installation port 208. At this time, the screw 202 is grasped, and the screw 202 rotates inside the screw hole 209. The rotational force of the screw 202 acts on the installation column 203, and the rotational force of the installation column 203 acts on the inside of the rotating seat 205. The longitudinal force acts on the clamping plate 204, and the clamping plate 204 is clamped on the high-voltage transmission line. The high-voltage transmission line is pressed and fixed. Through the functional characteristics of the anti-vibration hammer body 100, the high-voltage transmission line is effectively anti-vibrated. At the same time, the preset installation of the screw 202 avoids the use of additional installation tools, and the carry-on items during installation are lighter, which improves the convenience during installation.

[0049] Example 2

[0050] See also Figure 1-Figure 5 As shown, this embodiment is based on the embodiment 1 and also includes:

[0051] as well as;

[0052] The anti-loosening structure 300 includes a support plate 302 located on one side of the mounting column 203 and connected to the inner wall of the upper end of the sleeve 207, a bearing 301 embedded in the inner wall of the upper end of the sleeve 207, a rotating shaft 304 rotatably inserted into the bearing 301, a block 307 located at one end of the rotating shaft 304, a limit block 305 located on the inner wall of one side of the support plate 302, a torsion spring 303 sleeved on the outer side of the rotating shaft 304 and with the inner wall of the sleeve 207 and the outer wall of the block 307 respectively at the upper and lower ends, and a card slot 308 arranged in a circular array on the outer wall of the mounting column 203.

[0053] A rotating block 306 is disposed at one end of the rotating shaft 304, and one end of the rotating block 306 is in contact with the outer wall of the limiting block 305;

[0054] Use of anti-loosening structure 300;

[0055] When the support column rotates, the inner wall of the outer wall slot 308 squeezes the block 307. When the block 307 is squeezed, it drives the rotating shaft 304 to rotate, and then applies a rotational force to the torsion spring 303. The torsion spring 303 contracts under the force. After the screw 202 stops rotating and the clamping plate 204 effectively holds the high-voltage transmission line, the screw 202 rotates in the opposite direction due to external force factors. The rotational force of the screw 202 acts on the block 307, but the force of the block 307 rotating in the opposite direction acts on the rotating block 306. The rotating block 306 is intercepted by the limit block 305, so that the block 307 is locked, thereby avoiding the loosening of the screw 202. During the use of the high-voltage transmission line anti-vibration hammer, the stability is improved, and long-term and stable anti-vibration of the high-voltage transmission line is achieved.
