Description

Technical Field

[0001] The utility model relates to the technical field of anti-vibration hammers, in particular to a wire anti-vibration hammer. Background Art

[0002] The pole position of high-voltage overhead lines 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 be subjected to periodic bending and fatigue damage. When the span of the overhead line is greater than 120 meters, anti-vibration hammers are generally used to reduce the vibration of the overhead line.

[0003] In Chinese utility model CN216598922U, an "anti-vibration hammer" is proposed. The device includes a steel strand, two clamping plates and two hammer heads. The steel strand is fixedly arranged on the clamping plates. The two hammer heads are respectively connected to the two ends of the steel strand. The two clamping plates are connected together by means of connecting bolts and are used to clamp the wire. One clamping plate end has a strip-shaped slot facing outward, and the other clamping plate end has a clamping strip, which is clamped in the strip-shaped slot to withstand the force of the two clamping plates moving away from each other. The device mainly solves the problem that the connecting bolts of the existing anti-vibration hammer are prone to loosening. Although the device improves the stability during connection, the overall structure is too large, resulting in an increase in its weight. At the same time, it is also more complicated to install, which virtually reduces the efficiency of the staff in installing and disassembling the anti-vibration hammer. Utility Model Content

[0030] To improve the moving efficiency of the first bearing block 41 and the second bearing block 42, refer to Figure 1 and Figure 2 In a preferred embodiment, a movable hole 31 is opened on the shell 3, and a first bearing block 41 and a second bearing block 42 are slidably connected in the movable hole 31.

The staff can pull the first bearing block 41 and the second bearing block 42 away from the wire through the pull buckle 45. When the first bearing block 41 and the second bearing block 42 are away from the wire, the vertical rod 43 drives the cross plate 44 to squeeze the spring bar 32, and the spring bar 32 is deformed by squeezing, and the cross plate 44 is prompted to move inside the shell 3, so that the first clamping block 51 and the second clamping block 52 on the first bearing block 41 and the second bearing block 42 are away from the wire body. It should be noted that a retractable cylinder is arranged inside the spring bar 32. Through the cooperation of the spring bar 32 and the retractable cylinder, it can play the same effect as a damper.

[0036] In order to better understand the present invention, the following Figure 1-Figure 4The working process of the wire anti-vibration hammer of the utility model is described in detail: when in use, the staff drives the first bearing block 41 and the second bearing block 42 to move in the opposite direction through the pull buckle 45. When the first bearing block 41 and the second bearing block 42 move in the opposite direction, the vertical rod 43 slides in the movable hole 31, and the vertical rod 43 drives the cross plate 44 to squeeze the spring bar 32 and the telescopic cylinder inside the spring bar 32, causing them to deform, so that the first bearing block 41 and the second bearing block 42 are separated from each other, and a gap is generated between the first clamping block 51 and the second clamping block 52, so that the wire body is conveniently placed in the gap. When the wire body is located between the first clamping block 51 and the second clamping block 52, the pull buckle 45 is stopped, and the spring bar 32 starts to reset and pushes the cross plate 44, causing the first bearing block 41 and the second bearing block 42 to move away from each other. The first and second clamping blocks 51 and 52 are moved toward each other, and the limiting block 521 at the lower end of the second clamping block 52 is inserted into the groove 511 at the lower end of the first clamping block 51, so that the first clamping block 51 and the second clamping block 52 form a whole, and then the bolt 54 penetrates the through hole 531 on the extension block 53 of the first and second clamping blocks 51, 52, so that the first and second clamping blocks 51, 52 are fastened, so that the device is connected to the linear body, wherein the spring bar 32 and the telescopic cylinder arranged inside function as a damper, which is used to limit the first bearing block 41 and the second bearing block 42. By arranging a connecting frame 21 at the lower end of the shell 3, and connecting the two connecting rods 2 and the hammer head 1 through the connecting frame 21, the vibration reduction effect of the device is ensured. The device is simple to install and disassemble, and can have a good vibration reduction effect, which greatly improves the working efficiency of the anti-vibration hammer.
