The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
Referring to fig. 1 and 2, in an embodiment, the damper 1 is disposed on the overhead wire 2 to reduce or eliminate vibration of the overhead wire 2 caused by wind, so as to prevent 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, the wire clamp 10 is used for clamping the overhead wire 2 so as to hang the weight 20 on the overhead wire 2, and the weight 20 hung 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 one 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, the clamp body 100 can be used for clamping the overhead wire 2 on one hand, and the locking assembly 200 can be used for setting the weight 20 on the other hand, so that the clamp body 100 can be locked to clamp the overhead wire 2, and the clamp body 100 is prevented from sliding relative to the overhead wire 2.
The clamp body 100 includes a connecting member 110, a first clamping arm 120 and a second clamping arm 130, wherein one end of the connecting member 110 is disposed on the first clamping arm 120, and the other end is disposed on the second clamping arm 130, and the connecting member 110 can connect the first clamping arm 120 and the second clamping arm 130 into a unified whole. The distance between the first clamping arm 120 and the second clamping arm 130 can be changed, and when the clamp is used, the first clamping arm 120 and the second clamping arm 130 are pulled, so that a distance larger than the wire diameter of the overhead wire 2 is generated between the first clamping arm 120 and the second clamping arm 130, and the clamp body 100 is conveniently arranged on the overhead wire 2 through the distance.
Furthermore, the connecting member 110, the first clamping arm 120 and/or the second clamping arm 130 have elasticity, which facilitates the operator to 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 greater than the wire diameter of the overhead wire 2, and the clamp 100 can automatically reset after the operator stops pulling the first clamping arm 120 and the second clamping arm 130, so as to prevent the clamp 100 from falling off the overhead wire 2. In the present embodiment, the connecting member 110, the first clamping arm 120 and the second clamping arm 130 have elasticity. Of course, in other embodiments, only one or two elements of the connector 110, the first clamping arm 120 and the second clamping arm 130 may have elasticity, or all of the connector 110, the first clamping arm 120 and the second clamping arm 130 may have no elasticity.
Further, a distance exists between one end of the first clamping arm 120 away from the connecting member 110 and one end of the second clamping arm 130 away from the connecting member 110, and an operator can insert a hand into the distance to pull the first clamping arm 120 and the second clamping arm 130 conveniently. Of course, in other embodiments, this spacing may be omitted.
In the present embodiment, the connecting member 110 is bent in an approximately arc shape, the first clip arm 120 is in a flat plate shape, and the second clip arm 130 is in an arc plate shape. Of course, in other embodiments, the shape of the clip body 100 can be flexibly configured, 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 is arc-shaped, one end of the second clamping arm 130 away from the connecting member 110 tilts, so that a distance exists between one end of the first clamping arm 120 away from the connecting member 110 and one end of the second clamping arm 130 away from the connecting member 110. Of course, in other embodiments, a distance may exist between the end of the first clamping arm 120 away from the connector 110 and the end of the second clamping arm 130 away from the connector 110 by removing a portion of the material on the end of the first clamping arm 120 away from the connector 110 and/or removing a portion of the material on the end of the second clamping arm 130 away from the connector 110.
The first clamping arm 120 is provided with a first through hole, and the second clamping arm 130 is provided with a second through hole. The locking assembly 200 includes a first rod 210, a first locking member 220 and a second locking member 230, wherein the first rod 210 is inserted into 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 disposed 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 disposed 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 be close to the first clamping arm 120.
When the clamping device is used, the first locking part 220 is separated from the first penetrating rod 210, the first penetrating rod 210 provided with the second locking part 230 is arranged in the first through hole and the second through hole in a penetrating manner, and the rotating wheel 231 is positioned on one side of the second clamping arm 130 far away from the first clamping arm 120. The first locking member 220 is disposed on the first threading 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.
When the rotating wheel 231 is rotated, 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 clamp body 100, so that the clamp body 100 clamps the overhead wire 2, and prevent the clamp body 100 from moving relative to the overhead wire 2. Because the clamp body 100 can clamp the overhead line 2 under the action of the locking assembly 200, the wire clamp 10 has better setting firmness, and the damper 1 comprising the wire clamp 10 can be prevented from sliding relative to the overhead line 2.
It should be noted that, as long as the rotating wheel 231 drives the second clamping arm 130 to be close to the first clamping arm 120, a distance exists between one end of the first clamping arm 120 away from the connecting member 110 and one end of the second clamping arm 130 away from the connecting member 110, an operator can conveniently insert a hand into the distance to conveniently pull the first clamping arm 120 and the second clamping arm 130. When the wheel 231 drives the second clamping arm 130 to approach the first clamping arm 120, the distance is reduced or even eliminated.
in this embodiment, the first fastening member 220 is a nut, and the first fastening member 220 is threadedly engaged with the threaded 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 be arranged in the first through hole and the second through hole. When the first locking member 220 is screwed on the first penetrating rod 210, the first penetrating rod 210 can be limited to a certain extent, and the first penetrating rod 210 is prevented from being separated from the clamp body 100 along the direction from the first through hole to the second through hole. It can be understood that the first clamping arm 120 has a flat plate-shaped design, which can improve the stability of the nut arrangement.
In another embodiment, the first fastening member 220 is a pin instead of the nut in this embodiment, and the first penetrating rod 210 has a pin hole, and the pin is inserted into the pin hole. The pin can be pulled away from the first through-rod 210, so that the first through-rod 210 can be inserted into the first through-hole and the second through-hole. When the pin is inserted into the pin hole, the first through-rod 210 can be limited to a certain extent, and 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 at least two pin holes are distributed along the length direction of the first penetration rod 210. The degree of locking the clip body 100 can be adjusted by inserting pins into different pin holes. Of course, in other embodiments, the first securing member 220 can be other elements other than a nut or a pin.
Referring to fig. 3, the locking assembly 200 further includes a rotating shaft 241, the first penetrating rod 210 is provided with a first shaft hole, the rotating wheel 231 is provided with a second shaft hole, and the rotating shaft 241 is disposed in the first shaft hole and the second shaft hole, so that the rotating wheel 231 can rotate relative to the first penetrating rod 210. Of course, in other embodiments, the rotating shaft 241 can be disposed on the first penetrating rod 210, and the rotating wheel 231 can be rotatably disposed on the rotating shaft 241. Alternatively, the rotating shaft 241 may be disposed on the rotating wheel 231, and the rotating shaft 241 may be rotatably disposed on the first penetrating rod 210, as long as it is ensured that the rotating wheel 231 can rotate relative to the first penetrating rod 210.
Further, when the first through rod 210 has a first shaft hole and the rotating wheel 231 has a second shaft hole, the locking assembly 200 further includes a first stopper 242 and a second stopper 243, the first stopper 242 is disposed on the rotating shaft 241, the second stopper 243 is detachably disposed on the rotating shaft 241, and the first through rod 210 and the rotating wheel 231 are both disposed between the first stopper 242 and the second stopper 243. The first stopper 242 and the second stopper 243 can prevent the first penetrating rod 210 and the rotating wheel 231 from moving away from each other along the length direction of the rotating shaft 241. Of course, in other embodiments, both the first stopper 242 and the second stopper 243 can be omitted.
in this embodiment, the first stopper 242 is a nut, the rotating shaft 241 and the first stopper 242 are combined to form a bolt, and the second stopper 243 is a nut. Of course, in other embodiments, the first stopper 242 and the second stopper 243 may be both nuts, and the rotating shaft 241 is a double-threaded 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 wheel 231, and a first arc surface 251 is formed on the fixing pad 250, and the first arc surface 251 is used for cooperating with the wheel 231 to fix the wheel 231. Of course, in other embodiments, the mounting pad 250 may be omitted.
referring to fig. 5, in another embodiment, the first arc surface 251 is provided with a locking groove 252, the peripheral wall of the rotating wheel 231 is provided with a locking block 232, 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 clamp body 100 is locked, the rotating wheel 231 is rotated until the locking block 232 extends into the locking groove 252, and the rotating wheel 231 stops rotating continuously. 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 shape of the locking slot 252 and the locking block 232 can be designed flexibly. 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 arc surface is formed on the fixing pad 250, and the second arc surface is located on a side of the first arc surface 251 away from the rotating wheel 231. The first arc 251 and the second arc exist at the same time, so that the fixing pad 250 is in an arc plate shape, and compared with the fixing pad 250 in another embodiment, the fixing pad 250 in the embodiment has a relatively thin thickness, which can effectively save materials. Of course, in other embodiments, the shape of the fixing 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 that the rotating wheel 231 can be rotated by 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 rod 210, the distance between the end of the first clamping arm 120 away from the connecting piece 110 and the end of the second clamping arm 130 away from the connecting piece 110 is the largest. When the clip body 100 is locked, the length direction of the handle 233 intersects with the length direction of the first penetration rod 210. In this embodiment, handle 233 in combination with runner 231 forms a quick release handle.
The anti-slip device further comprises an anti-slip pad (not shown), the anti-slip pad is arranged on the connecting piece 110, the connecting piece 110 is used for being attached to the overhead line 2, and the anti-slip pad is located on one side, used for being attached to the overhead line 2, of the connecting piece 110. The presence of the non-slip mat increases the friction between the connector 110 and the overhead wire 2 to further prevent slippage of the hoop relative to the overhead wire 2, thereby preventing slippage of the damper 1. The non-slip mat can be a plastic mat with flexibility or a rubber mat and the like. Of course, in other embodiments, the non-slip mat may be omitted.
Referring to fig. 6, the connecting member 110 includes a first connecting member 111, a second connecting member 112, a first engaging head 113 disposed on the first connecting member 111, and a second engaging head 114 disposed on the second connecting member 112, wherein the first engaging head 113 and the second engaging head 114 are detachably engaged. When the clamp is used, the locking assembly 200 is not required to be detached from the clamp body 100, so that the first matching head 113 and the second matching head 114 are separated, the clamp body 100 is conveniently arranged on the overhead line 2 through the separation position of the first matching head 113 and the second matching head 114, and the clamp is simple and convenient. After the clamp 100 is disposed on the overhead wire 2, the first engaging head 113 is engaged with the second engaging head 114 to prevent the clamp 100 from falling off the overhead wire 2. The rotating wheel 231 is rotated to make the second clamping arm 130 close to the first clamping arm 120, so as to lock the clamp body 100. The separable mating manner of the first mating head 113 and the second mating head 114 may be a snap fit or the like.
It should be noted that, in the present embodiment, the non-slip mat includes a first non-slip mat and a second non-slip mat, the first non-slip mat is disposed on the first connecting member 111, and the second non-slip mat is disposed on the second connecting member 112, so that the first engaging head 113 and the second engaging head 114 can be detachably engaged with each other.

When the fitting structure is used, the fourth locking member 117 is separated from the second penetrating rod 115, the second penetrating rod 115 provided with the third locking member 116 is arranged in the third through hole and the fourth through hole in a penetrating manner, and the third locking member 116 is located on one side, away from the first fitting head 113, of the second fitting head 114. The fourth locking member 117 is disposed on the second penetrating rod 115, such that the fourth locking member 117 is disposed on a side of the first engaging head 113 away from the second engaging head 114. The presence of second through rod 115, third locking member 116 and fourth locking member 117 can improve the fit firmness of first fitting head 113 and second fitting head 114.
In this embodiment, the third locking member 116 and the fourth locking member 117 are both nuts, and the third locking member 116 and the fourth locking member 117 are both in threaded fit with the second rod 115. When in use, any end of the second through-rod 115 can be sequentially passed through the third through-hole and the fourth through-hole, so that the operation convenience is high. In yet another embodiment, the third locking member 116 is a nut, the fourth locking member 117 is a nut, and the fourth locking member 117 is threadedly engaged with the second threaded rod 115. The second through rod 115 and the third locking member 116 can form a bolt, and the firmness is better. Of course, in other embodiments, the second through rod 115, the third locking member 116 and the fourth locking member 117 can be flexibly disposed.

The wire clamp 10 may further include a fourth elastic member (not shown) sleeved on the first rod 210, wherein the fourth elastic member is located between the fixing pad 250 and the second clamping arm 130. The fourth elastic member can play a role in buffering, and when the runner 231 drives the second clamping arm 130 to be close to the first clamping arm 120, the fourth elastic member can also play a role in compressing the runner 231, so as to prevent the runner 231 from rotating to a certain extent. The fourth elastic element can be a pressure spring, an elastic cushion or the like. In this embodiment, the fourth elastic member is omitted.
Referring to fig. 1 and fig. 2, the weight 20 is disposed on the clip 100, and the weight 20 can be disposed fixedly or detachably. Specifically, in the present embodiment, the weight 20 is disposed on the first clamping arm 120, and can straighten the first clamping arm 120 to a certain extent, so as to prevent the first clamping arm 120 from bending. Furthermore, the weight 20 is detachably disposed on the first clamping arm 120, so that the clamp body 100 and the weight 20 can be manufactured independently. Of course, in other embodiments, the weight 20 can be disposed on the connecting member 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, the connecting cable 21 generates internal friction to consume a part of vibration energy, and the damping of the air on the first hammer 22 and the second hammer 23 can also consume a part of vibration energy, 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 with a vibration absorbing ball disposed therein, wherein the vibration absorbing 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 body 100, and the connecting cable 21 is disposed through the wire barrel. The existence of the mounting plate can facilitate the detachable arrangement of the heavy hammer 20, and the existence of the wire barrel can play a certain role in protecting the connecting cable 21.
The damper 1 and the wire clamp 10 thereof have at least the following advantages:
before use, the weight 20 is set on the clip body 100. The first locking member 220 can be separated from the first penetrating rod 210, and the first penetrating rod 210 with the second locking member 230 can be inserted into 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 threading 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.
When in use, the first engaging head 113 is separated from the second engaging head 114, so that the clamp 100 is disposed on the overhead line 2 through the separation position of the first engaging head 113 and the second engaging head 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 on one side of the second matching head 114 away from the first matching head 113. The fourth locking member 117 is disposed on the second penetrating rod 115, such that the fourth locking member 117 is disposed on a side of the first engaging head 113 away from the second engaging head 114. The second through rod 115, the third locking member 116 and the fourth locking member cooperate to firmly engage the first engaging head 113 with the second engaging head 114.
When the grip 233 is rotated to test the degree of tightness and the resistance is not sensed when the longitudinal direction of the grip 233 is the same as the longitudinal direction of the first threading rod 210, the first locking member 220 is moved to bring the first locking member 220 close to the turning wheel 231 until the resistance is sensed when the longitudinal direction of the grip 233 is the same as the longitudinal direction of the first threading rod 210. When the handle 233 is rotated, the roller 231 is rotated until the locking block 232 is inserted into the locking groove 252.
When the rotating wheel 231 is rotated, since the rotating wheel 231 is a cam or an eccentric wheel, the rotating wheel 231 can drive the second clamping arm 130 to be close to the first clamping arm 120, so as to lock the clamp body 100, so that the clamp body 100 clamps the overhead wire 2, and prevent the clamp body 100 from slipping relative to the overhead wire 2. Because the clamp body 100 can clamp the overhead line 2 under the action of the locking assembly 200, the wire clamp 10 has better setting firmness, and the damper 1 comprising the wire clamp 10 can be prevented from sliding relative to the overhead line 2.
It should be noted that, in this embodiment, the second penetrating rod 115, the third locking member 116, the fourth locking and locking assembly 200 cooperate to lock the clip body 100, so as to effectively increase the degree of clamping the overhead wire 2 by the clip body 100, and further prevent the clip body 100 from sliding relative to the overhead wire 2, thereby improving the setting firmness of the damper 1 and the wire clamp 10 thereof, and preventing the damper 1 from sliding relative to the overhead wire 2.
When the clamp is disassembled, the handle 233 can be rotated reversely, so that the degree of clamping the overhead wire 2 by the clamp body 100 is reduced. The fourth locking member 117 is separated from the second threading rod 115, and the second threading rod 115 provided with the third locking member 116 is removed from the fourth threading rod through the third through hole and the fourth through hole, so that the first engaging head 113 is separated from the second engaging head 114. The wire clamp 10 is removed from the overhead wire 2 via the separation of the first mating head 113 from the second mating head 114.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
