Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
Referring to fig. 1 and 2, a damper 1 in an embodiment is configured to be disposed on an overhead wire 2 to reduce or eliminate vibration generated by the overhead wire 2 under the action of wind force, thereby preventing fatigue failure of the overhead wire 2. The damper 1 comprises a wire clamp 10 and a weight 20 arranged on the wire clamp 10, wherein the wire clamp 10 is used for clamping the overhead wire 2 so as to suspend the weight 20 on the overhead wire 2, and the weight 20 suspended on the overhead wire 2 can move relative to the overhead wire 2 so as to absorb energy generated when the overhead wire 2 vibrates.
The wire clamp 10 in an embodiment has at least the characteristic of better setting firmness, and can prevent the damper 1 from sliding relative to the overhead wire 2. Specifically, the wire clamp 10 includes a clamp body 100 and a locking assembly 200, wherein the clamp body 100 can be used for clamping an overhead wire 2 on one hand, and can be used for providing a weight 20 on the other hand, and the locking assembly 200 is used for locking the clamp body 100 so that the clamp body 100 clamps the overhead wire 2 and prevents the clamp body 100 from sliding relative to the overhead wire 2.
The clip body 100 includes a connecting member 110, a first clip arm 120 and a second clip arm 130, one end of the connecting member 110 is disposed on the first clip arm 120, the other end is disposed on the second clip arm 130, and the first clip arm 120 and the second clip arm 130 can be connected into a unified whole by the connecting member 110. The distance between the first clamping arm 120 and the second clamping arm 130 can be changed, and when in use, the first clamping arm 120 and the second clamping arm 130 are pulled to generate a distance between the first clamping arm 120 and the second clamping arm 130, which is larger than the wire diameter of the overhead wire 2, so that the clamping body 100 is arranged on the overhead wire 2 through the distance.
Further, the connecting piece 110, the first clamping arm 120 and/or the second clamping arm 130 have elasticity, so that on one hand, an operator can conveniently pull the first clamping arm 120 and the second clamping arm 130 to generate a distance between the first clamping arm 120 and the second clamping arm 130, which is larger than the wire diameter of the overhead wire 2, and on the other hand, after the operator stops pulling the first clamping arm 120 and the second clamping arm 130, the clamping body 100 can automatically reset to prevent the clamping body 100 from falling off from the overhead wire 2. In the present embodiment, the connection member 110, the first clamping arm 120, and the second clamping arm 130 have elasticity. Of course, in other embodiments, only one or two of the connecting member 110, the first clamping arm 120 and the second clamping arm 130 may be elastic, or none of the connecting member 110, the first clamping arm 120 and the second clamping arm 130 may be elastic.
Further, a space exists between an end of the first clamping arm 120 away from the connecting member 110 and an end of the second clamping arm 130 away from the connecting member 110, and an operator can extend his or her hand into the space to pull the first clamping arm 120 and the second clamping arm 130. Of course, in other embodiments, the spacing may be omitted.
In the present embodiment, the connecting member 110 is bent to have a substantially arc shape, the first clamping arm 120 has a flat plate shape, and the second clamping arm 130 has a curved plate shape. Of course, in other embodiments, the shape of the clip body 100 can be flexibly set, for example, the first clip arm 120 and the second clip arm 130 are both block-shaped.
In this embodiment, since the second clamping arm 130 has an arc-shaped plate shape, the end of the second clamping arm 130 away from the connecting member 110 is tilted, such that a space exists between the end of the first clamping arm 120 away from the connecting member 110 and the end of the second clamping arm 130 away from the connecting member 110. Of course, in other embodiments, a space may exist between an end of the first clip arm 120 distal from the connector 110 and an end of the second clip arm 130 distal from the connector 110 by removing a portion of material on an end of the first clip arm 120 distal from the connector 110 and/or removing a portion of material on an end of the second clip arm 130 distal from the connector 110.
The first clamping arm 120 has a first through hole, and the second clamping arm 130 has a second through hole. The locking assembly 200 includes a first penetrating rod 210, a first locking member 220 and a second locking member 230, where the first penetrating rod 210 penetrates through the first through hole and the second through hole. The first locking member 220 is detachably disposed on the first penetrating rod 210, the first locking member 220 is located on a side of the first clamping arm 120 facing away from the second clamping arm 130, the second locking member 230 includes a rotating wheel 231, the rotating wheel 231 is rotatably disposed on the first penetrating rod 210, the rotating wheel 231 is a cam or an eccentric wheel, the rotating wheel 231 is located on a side of the second clamping arm 130 facing away from the first clamping arm 120, and the rotating wheel 231 can drive the second clamping arm 130 to approach the first clamping arm 120.
In use, the first locking member 220 is separated from the first penetrating rod 210, the first penetrating rod 210 provided with the second locking member 230 is penetrated into the first through hole and the second through hole, and the rotating wheel 231 is located at the side of the second clamping arm 130 away from the first clamping arm 120. The first locking member 220 is disposed on the first penetrating rod 210, such that the first locking member 220 is located on a side of the first clamping arm 120 away from the second clamping arm 130.
The rotating wheel 231 is rotated, and since the rotating wheel 231 is a cam or an eccentric wheel, the rotating wheel 231 can drive the second clamping arm 130 to approach the first clamping arm 120 so as to lock the clamping body 100, so that the clamping body 100 clamps the overhead line 2, and the clamping body 100 is prevented from moving relative to the overhead line 2. Since the clamp body 100 can clamp the overhead wire 2 under the action of the locking assembly 200, the arrangement firmness of the wire clamp 10 is good, and the damper 1 including the wire clamp 10 can be prevented from slipping relative to the overhead wire 2.
It should be noted that, as long as a space exists between the end of the first clamping arm 120 far away from the connecting piece 110 and the end of the second clamping arm 130 far away from the connecting piece 110 before the rotating wheel 231 drives the second clamping arm 130 to approach the first clamping arm 120, an operator can conveniently extend a hand into the space, so as to conveniently pull the first clamping arm 120 and the second clamping arm 130. When the wheel 231 moves the second arm 130 closer to the first arm 120, the spacing is reduced or even eliminated.
In this embodiment, the first locking member 220 is a nut, and the first locking member 220 is in threaded engagement with the through rod. The first locking member 220 can be unscrewed from the first penetrating rod 210, so as to facilitate the first penetrating rod 210 to penetrate into the first through hole and the second through hole. When the first locking member 220 is screwed onto the first penetrating rod 210, a certain limiting effect is provided for the first penetrating rod 210, so as to prevent the first penetrating rod 210 from being separated from the clip body 100 along the direction from the first through hole to the second through hole. It can be appreciated that the flat design of the first clamping arm 120 can improve the stability of the nut arrangement.
In another embodiment, the first locking member 220 is a pin, instead of the nut in this embodiment, the first through rod 210 is provided with a pin hole, and the pin is inserted into the pin hole. The pin can be pulled out of the first through rod 210, so that the first through rod 210 can be conveniently penetrated into the first through hole and the second through hole. When the pin is inserted into the pin hole, a certain limiting effect can be achieved on the first through rod 210, so that the first through rod 210 is prevented from being separated from the clip body 100 along the direction from the first through hole to the second through hole. The number of the pin holes may be at least two, and the at least two pin holes are distributed along the length direction of the first penetration rod 210. The degree of locking of the clip body 100 can be adjusted by inserting pins into different pin holes. Of course, in other embodiments, first retaining member 220 may also be other elements than a nut or pin.
Referring to fig. 3, the locking assembly 200 further includes a rotating shaft 241, a first shaft hole is formed in the first penetrating rod 210, a second shaft hole is formed in the rotating wheel 231, and the rotating shaft 241 is disposed in the first shaft hole and the second shaft hole in a penetrating manner, so that the rotating wheel 231 can rotate relative to the first penetrating rod 210. Of course, in other embodiments, the rotating shaft 241 may be disposed on the first penetrating rod 210, and the rotating wheel 231 may be rotatably disposed on the rotating shaft 241. Alternatively, the rotating shaft 241 may be disposed on the rotating wheel 231, where the rotating shaft 241 is rotatably disposed on the first penetrating rod 210, so long as the rotating wheel 231 can rotate relative to the first penetrating rod 210.
Further, when the first shaft hole is formed in the first penetrating rod 210 and the second shaft hole is formed in the rotating wheel 231, the locking assembly 200 further includes a first limiting block 242 and a second limiting block 243, the first limiting block 242 is disposed on the rotating shaft 241, the second limiting block 243 is detachably disposed on the rotating shaft 241, and the first penetrating rod 210 and the rotating wheel 231 are both disposed between the first limiting block 242 and the second limiting block 243. The first limiting block 242 and the second limiting block 243 can prevent the first penetrating rod 210 and the rotating wheel 231 from being far away from each other along the length direction of the rotating shaft 241. Of course, in other embodiments, the first limiting block 242 and the second limiting block 243 can be omitted.
In this embodiment, the first limiting block 242 is a nut, the rotating shaft 241 and the first limiting block 242 are combined to form a bolt, and the second limiting block 243 is a nut. Of course, in other embodiments, the first limiting block 242 and the second limiting block 243 can be nuts, and the rotating shaft 241 is a double-ended screw.
Referring to fig. 2 and 4, the locking assembly 200 further includes a fixing pad 250, the fixing pad 250 is located between the second clamping arm 130 and the rotating wheel 231, and a first arc surface 251 is formed on the fixing pad 250, and the first arc surface 251 is used for being matched with the rotating wheel 231 so as to fix the rotating wheel 231. Of course, in other embodiments, the mounting pad 250 may be omitted.
Referring to fig. 5, in another embodiment, a locking groove 252 is formed on the first arc surface 251, a locking block 232 is disposed on the peripheral wall of the rotating wheel 231, and the locking block 232 can extend into the locking groove 252 to prevent the rotating wheel 231 from continuing to rotate to a certain extent. When the clip body 100 is locked, the rotation of the rotation wheel 231 is stopped until the locking block 232 extends into the locking groove 252. When the locking assembly 200 is removed, the rotating wheel 231 is rotated in the opposite direction.
Specifically, in another embodiment, the fixing pad 250 may be substantially cylindrical, the locking groove 252 may be a bar-shaped groove, and the locking block 232 may be bar-shaped. Of course, in other embodiments, the shapes of the locking groove 252 and the locking block 232 can be flexibly designed. Alternatively, the locking groove 252 and the locking block 232 may be omitted.
Referring to fig. 2 and 4, in the present embodiment, a second cambered surface is formed on the fixing pad 250, and the second cambered surface is located at a side of the first cambered surface 251 away from the rotating wheel 231. The first cambered surface 251 and the second cambered surface exist simultaneously, so that the fixing pad 250 is in an arc plate shape, and compared with the fixing pad 250 in another embodiment, the thickness of the fixing pad 250 in the embodiment is relatively thinner, and the material can be effectively saved. Of course, in other embodiments, the shape of the mounting pad 250 may be flexibly designed.
Referring to fig. 2, the second locking member 230 further includes a handle 233, and the handle 233 is disposed on the rotating wheel 231 so as to rotate the rotating wheel 231 through the handle 233. In this embodiment, when the length direction of the handle 233 is the same as the length direction of the first penetrating bar 210, the distance between the end of the first clamping arm 120 away from the connecting member 110 and the end of the second clamping arm 130 away from the connecting member 110 is the largest. When the clip body 100 is locked, the length direction of the handle 233 intersects the length direction of the first penetrating bar 210. In this embodiment, the handle 233 in combination with the wheel 231 may form a quick release handle.
The anti-slip device further comprises an anti-slip pad (not shown) disposed on the connecting member 110, wherein the connecting member 110 is used for being attached to the overhead line 2, and the anti-slip pad is located on one side of the connecting member 110, which is used for being attached to the overhead line 2. The presence of the anti-slip pad increases the friction between the connector 110 and the overhead wire 2 to further prevent slippage of the anchor ear relative to the overhead wire 2 and thus the damper 1. The non-slip mat may be a plastic mat or a rubber mat having flexibility, etc. Of course, in other embodiments, the cleat may be omitted.
Referring to fig. 6, the connecting member 110 includes a first connecting member 111, a second connecting member 112, a first fitting head 113 disposed on the first connecting member 111, and a second fitting head 114 disposed on the second connecting member 112, wherein the first fitting head 113 and the second fitting head 114 are detachably engaged. When in use, the clamp body 100 can be separated from the first matching head 113 and the second matching head 114 without the locking assembly 200, so that the clamp body 100 can be arranged on the overhead line 2 through the separation of the first matching head 113 and the second matching head 114, and the operation is simple and convenient. When the clip body 100 is disposed on the overhead line 2, the first fitting head 113 is fitted with the second fitting head 114 to prevent the clip body 100 from falling off the overhead line 2. The rotating wheel 231 is rotated to bring the second clamping arm 130 close to the first clamping arm 120 so as to lock the clamping body 100. The separable mating manner of the first mating head 113 and the second mating head 114 may be a clamping manner.

Referring to fig. 1 and 2, the weight 20 is disposed on the clamp 100, and the weight 20 may be fixed or detachable. In this embodiment, the weight 20 is disposed on the first arm 120, which can straighten the first arm 120 to a certain extent to prevent the first arm 120 from bending. Further, the weight 20 is detachably disposed on the first clamping arm 120, so as to manufacture the clamping body 100 and the weight 20 independently. Of course, in other embodiments, the weight 20 can also be disposed on the connecting piece 110 or the second clamping arm 130.
The weight 20 includes a connecting cable 21, a first hammer 22, and a second hammer 23, and the first hammer 22 and the second hammer 23 are respectively disposed at two ends of the connecting cable 21. When the overhead line 2 vibrates, the first hammer 22 and the second hammer 23 move up and down, and part of vibration energy can be consumed by internal friction generated by the connecting cable 21, and part of vibration energy can also be consumed by damping of the first hammer 22 and the second hammer 23 by air, so that the vibration of the overhead line 2 is reduced or eliminated. The connecting cable 21 may be a steel strand or a hollow tube provided with a vibration damping ball inside, wherein the vibration damping ball may be a steel ball or the like.
Further, the weight 20 further includes a mounting plate (not shown) and a wire barrel (not shown) disposed on the mounting plate, the mounting plate is disposed on the clamp 100, and the connecting cable 21 is inserted into the wire barrel.

The damper 1 and the wire clamp 10 thereof have at least the following advantages:
before use, weight 20 is placed on clamp 100. The first locking member 220 may be separated from the first penetrating rod 210, and the first penetrating rod 210 provided with the second locking member 230 may be penetrated through the first through hole and the second through hole, so that the rotating wheel 231 is located at a side of the second clamping arm 130 away from the first clamping arm 120. The first locking member 220 is disposed on the first penetrating rod 210, such that the first locking member 220 is located on a side of the first clamping arm 120 away from the second clamping arm 130.
In use, the first and second fitting heads 113 and 114 are separated so that the clip body 100 is disposed on the overhead line 2 via the separation of the first and second fitting heads 113 and 114. The fourth locking member 117 is separated from the second penetrating rod 115, and the second penetrating rod 115 provided with the third locking member 116 is penetrated into the third through hole and the fourth through hole, so that the third locking member 116 is positioned at a side of the second fitting head 114 away from the first fitting head 113. The fourth locking member 117 is disposed on the second penetrating rod 115 such that the fourth locking member 117 is located at a side of the first coupling head 113 remote from the second coupling head 114. The second penetrating rod 115, the third locking member 116 and the fourth locking member cooperate to firmly engage the first engagement head 113 with the second engagement head 114.
The handle 233 is rotated to test tightness, and if resistance is not sensed when the length direction of the handle 233 is in the same direction as the length direction of the first penetration rod 210, the first locking member 220 is moved to approach the rotating wheel 231 until resistance is sensed when the length direction of the handle 233 is in the same direction as the length direction of the first penetration rod 210. The handle 233 is turned, and the turning wheel 231 is turned until the locking block 232 extends into the locking groove 252.
The rotating wheel 231 is rotated, and since the rotating wheel 231 is a cam or an eccentric wheel, the rotating wheel 231 can drive the second clamping arm 130 to approach the first clamping arm 120 so as to lock the clamping body 100, so that the clamping body 100 clamps the overhead line 2, and the clamping body 100 is prevented from sliding relative to the overhead line 2. Since the clamp body 100 can clamp the overhead wire 2 under the action of the locking assembly 200, the arrangement firmness of the wire clamp 10 is good, and the damper 1 including the wire clamp 10 can be prevented from slipping relative to the overhead wire 2.
It should be noted that, in this embodiment, the second penetrating rod 115, the third locking member 116, and the fourth locking and locking assembly 200 cooperate to lock the clamp body 100, so that the degree of clamping the overhead wire 2 by the clamp body 100 is effectively increased, and the clamp body 100 can be further prevented from sliding relative to the overhead wire 2, thereby improving the setting firmness of the damper 1 and the wire clamp 10 thereof, and avoiding the damper 1 from sliding relative to the overhead wire 2.
When the trolley wire 2 is detached, the handle 233 can be reversely rotated, so that the degree of clamping the trolley wire 2 by the clamp body 100 is reduced. The fourth locking member 117 is separated from the second penetrating rod 115, and the second penetrating rod 115 provided with the third locking member 116 is detached from the fourth penetrating hole via the third penetrating hole to separate the first fitting head 113 from the second fitting head 114. The wire clamp 10 is removed from the overhead wire 2 via the separation of the first fitting head 113 from the second fitting head 114.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
