Description

A stereotyped anti-vibration hammer

technical field

The utility model relates to the technical field of protective hardware for transmission lines, in particular to a stereotyped anti-vibration hammer.

Background technique

In the daily operation and maintenance of transmission lines, a large number of anti-vibration hammers will be displaced. Only statistics were made on the transmission lines of main grid frames such as ±800kV DC lines patrolled by helicopters in the Guangdong region in the first half of 2017, and a large number of anti-vibration hammers were found to be displaced. Through analysis, it is found that the main reason for the displacement of the anti-vibration hammer is that the currently used anti-vibration hammer is in contact with the ground wire through the aluminum tape, and then tightened and fixed by bolts, so that the anti-vibration hammer cannot completely fit the ground wire. If only the anti-vibration hammer is installed without the aluminum tape, the anti-vibration hammer will not be able to fully fit the ground wire, and the ground wire will be worn out under the long-term vibration of the ground wire.

Operators have a heavy workload when resetting the displaced anti-vibration hammer, especially when resetting the anti-vibration hammer with large span and high tower and large span displacement, the operation risk will increase. The current anti-slip anti-vibration hammer mainly adopts the form of pre-twisted wire. The whole device has many parts, complicated installation, and high cost, and the anti-vibration hammer is fixed by pre-twisted wire winding, which will cause the anti-vibration hammer to rotate around the ground wire in situ. Will cause the ground wire to be worn.

Utility model content

In order to solve the above problems, the utility model provides a stereotyped anti-vibration hammer in order to achieve the technical effect of avoiding the displacement of the anti-vibration hammer.

In order to achieve the above object, the technical solution of the utility model is:

A stereotyped anti-vibration hammer, including a hammer head, a steel strand, and a wire clamp. The wire clamp includes a wire clamp moving body and a wire clamp main body. Groove, the groove is provided with threads, the wire clamp moving body and the wire clamp main body are fixed by bolts, the wire clamp moving body and the wire clamp main body are fixed to form an inner circular structure, and the wire clamp and the steel strand The middle section of the steel strand is connected, and the two ends of the steel strand are respectively connected with the hammer head.

Further, the thread pattern matches the winding pattern of the ground wire.

The utility model mainly adopts the anti-slip thread that matches the winding pattern of the wire. After the anti-vibration hammer is installed on the ground wire, the thread of the anti-vibration hammer and the raised thread of the ground wire can be completely fitted, increasing the contact area between the ground wire and the anti-vibration hammer. , the friction force increases; and because the thread of the ground wire is helically wound, it will generate resistance to the anti-vibration hammer. Through the above two points, the problem of slippage of the anti-vibration hammer is solved.

Compared with the prior art, the utility model has the beneficial effects of:

The device is simple, the installation is convenient, it will not move in place, the change to the traditional clamp is small, the cost is low, and it is convenient for large-scale promotion and trial in transmission lines.

Detailed ways

The content of the present utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Example 1:

A stereotyped anti-vibration hammer, including a hammer head 1, a steel strand 2 and a wire clamp 3, the wire clamp 3 includes a wire clamp moving body 5 and a wire clamp main body 6, and the wire clamp moving body 5 and the wire clamp main body 6 The inner side is provided with a semicircular groove, the groove is provided with a thread 7, the wire clamp moving body 5 and the wire clamp main body 6 are fixed by bolts 4, and the wire clamp moving body 5 and the wire clamp main body 6 are fixed Finally, an inner circular structure is formed, the clamp 3 is connected to the middle section of the steel strand 2, and the two ends of the steel strand 2 are connected to the hammer head 1 respectively.

Wherein, the texture of the thread 7 matches the winding texture of the ground wire.

When in use, first loosen the bolt 4, put the wire into the wire clamp moving body 5 and the wire clamp main body 6 to form an inner circular structure after being fixed, the wire clamp main body 6 is fixed, by adjusting the wire clamp moving body 5, Make the wire clip 3 suitable for various types of wires, and finally lock the bolt 4.

When the wire is subjected to wind force, it will vibrate. When the conductor vibrates, the working conditions are the most unfavorable where the conductor is suspended. Due to multiple vibrations, the conductor will be fatigued and damaged due to periodic bending. The utility model fits the wire more completely, so that the vibration of the wire is eliminated or weakened. And the troublesome work of resetting is avoided.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present utility model, and its purpose is to allow those of ordinary skill in the art to understand the content of the present utility model and implement it accordingly, and cannot limit the protection scope of the present utility model with this . All equivalent changes or modifications made according to the essence of the content of the utility model shall fall within the scope of protection of the utility model.
