Description
Technical Field
[0001] The invention belongs to the technical field of anti-vibration hammers, and in particular relates to a follow-up anti-vibration hammer and a design method of the follow-up anti-vibration hammer. Background Art
[0002] At present, the vibration resistance of aluminum alloy core aluminum stranded wire is weaker than that of steel core aluminum stranded wire with the same technical conditions. When used on UHV lines, since UHV lines are generally at an altitude of 100 meters and UHV lines pass through open plains in large quantities with abundant breezes, they can output a stable breeze climate of 0.5m / s-5m / s all year round. Once the wind direction is at an angle of 30°-90° with the transmission line travel, efficient line conductor breeze vibration will occur.
[0003] The combination of anti-vibration hammer and conductor self-damping spacer is the most commonly used anti-vibration measure for UHV conductors. However, due to the lack of in-depth research on anti-vibration hammers in China, the produced anti-vibration hammers can only cover the vibration frequency range of the conductors, and cannot effectively respond to the main resonant frequency of the conductors, and cannot exert the highest efficiency of the anti-vibration hammers, thereby minimizing the vibration level of the conductors and controlling the vibration level of the conductors within the standard value. Under this condition, especially when the vibration of aluminum alloy core aluminum stranded wire conductors exceeds the standard, the probability of strain exceeding 150 will be greatly increased. In the long run, it will cause the conductors to break due to vibration fatigue and then break, which seriously threatens the safety of UHV transmission lines.

[0058] like Fig.11 and Fig.12 As shown, an adjusting box 33 is installed on the side of the fixed part 20, and a moving part 35 is slidably connected in the adjusting box 33. An electric push rod 2 34 is installed on the adjusting box 33. The piston rod end of the electric push rod 2 34 passes through the top of the adjusting box 33 and is fixedly connected to the moving part 35. A sliding groove 2 is opened on the side of the adjusting box 33, and the steel strand 10 is hinged to the moving part 35.
[0059] In the present invention, two limiting wheels 26 are installed on the eccentric shaft 22, and the gear 24 is located between the two limiting wheels 26. Two limiting wheels 27 are installed on the eccentric shaft 23, and the gear 25 is located between the two limiting wheels 27.

[0060] In the present invention, the eccentric shaft 1 22 , the two limiting wheels 1 26 , and the gear 1 24 are all eccentrically arranged, and the eccentric shaft 2 23 , the two limiting wheels 27 , and the gear 2 25 are all eccentrically arranged.
[0061] In the present invention, the second motor 14 is installed on the side of the lifting member 15.
[0062] In the present invention, adsorption members 13 are provided on both sides of the follower block 5 , and the adsorption members 13 cooperate with the guide rail 3 .

[0066] The working principle of this embodiment is as follows: on the basis of Embodiment 1, through the signals transmitted by the wind direction sensor, sensor 1 and wind force sensor, the controller calculates the optimal position of the hammer 11, and the controller controls the motor 2 14 to turn on, and the motor 2 14 drives the eccentric shaft 1 22 to rotate, and the gear 1 24 and the gear 2 25 on the eccentric shaft 1 22 are meshed.

[0070] In the present invention, the electromagnetic power supply of the adsorption member 2 37 needs to be disconnected only before the electric push rod 2 34 is turned on, so that the electromagnet of the adsorption member 2 37 and the corresponding position of the steel strand 10 are disconnected, so that the electric push rod 2 34 can drive the steel strand 10 to move up and down continuously in the slide groove 2.
[0071] In the present invention, after the follower block 5 moves to a suitable position along the guide rail 3, the controller turns on the electromagnetic power supply of the adsorption member 13, so that the electromagnet of the adsorption member 13 is adsorbed to the outer periphery of the guide rail 3, thereby fixing the position of the follower block 5 on the guide rail 3.

[0073] The main differences between this embodiment and embodiment 1 are:
[0074] A method for designing a follow-up anti-vibration hammer, used for designing the follow-up anti-vibration hammer, comprises the following steps:
[0075] Step 1: Perform a vibration test on conductor 1;
[0076] Step 2: extracting and classifying the vibration exceeding standard data of conductor 1;
[0077] Step 3: Determine the data of the follow-up anti-vibration hammer;
[0078] Step 4: Verify the resonance frequency of the follow-up anti-vibration hammer and adjust the follow-up anti-vibration hammer.
[0079] In the present invention, the conductor 1 is an aluminum alloy core aluminum stranded wire.
[0080] Step one includes: using a laser vibrometer to obtain the characteristics of mechanical vibration or instantaneous vibration process using the principle of heterodyne interferometer. The test light emitted by the laser vibrometer carries the vibration information of the object after being reflected from the object, is reflected back to the fiber optic probe, and is transmitted to a high-precision laser interferometer via the optical fiber, where it interferes with the reference light. The interference signal carries signals such as the speed, displacement, acceleration, and vibration frequency of the object's vibration. The corresponding information can be obtained through signal demodulation, filtering, amplification, and other processing.
[0081] Step 2 includes: detecting the fatigue danger point of conductor 1 with a laser vibrometer, and conductor 1 includes eight sub-conductors, and selecting one of the upper four and one of the lower four for detection, to obtain the exceeding standard data extracted by the vibration test of conductor 1, and the maximum dynamic bending strain is greater than 150; frequency classification of the exceeding standard data of conductor 1 vibration, determining the maximum and minimum values, obtaining the number of occurrences of frequencies in different ranges at intervals of 5 Hz, and making a pivot table. By analyzing the pivot table, the main characteristics of the exceeding standard of conductor 1 vibration and the exceeding proportion of each main over-frequency band can be determined, and the selection range and coverage efficiency of the resonant frequency of the follow-up anti-vibration hammer can be determined.
[0082] Step three includes: determining the follow-up anti-vibration hammer data, that is, all the data required for the existing anti-vibration hammer, according to the resonant frequency range of the follow-up anti-vibration hammer determined in step two.
[0083] The total mass calculation formula of the anti-vibration hammer is: m=0.4d-2.2; m is the total mass of the anti-vibration hammer, unit: kg; d is the diameter of the conductor 1, unit: mm.
[0084] Step 4 includes: classifying the vibration exceeding standard data of conductor 1, screening out the main vibration frequency and proportion of conductor 1, verifying the frequency of the follow-up anti-vibration hammer through the follow-up anti-vibration hammer characteristic test, and adjusting the follow-up anti-vibration hammer in step 3.
