When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "first," "second," "third," and "fourth" herein do not denote a particular quantity or order, but rather are used for distinguishing between similar or identical names.

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, an anti-slip device 10 in an embodiment can be disposed on an overhead line 20 to prevent a damper 30 from slipping. Further, the anti-slip device 10 is located at a side of the damper 30 away from the tower, so as to prevent the damper 30 from slipping along the overhead line 20 in a direction away from the tower, thereby preventing fatigue failure of the overhead line 20. In the present embodiment, the anti-slip device 10 abuts against the damper 30.

Referring to fig. 2, specifically, the anti-sliding device 10 includes a hoop 100 and a locking assembly 200, the hoop 100 is configured to be disposed around the overhead line 20, and the locking assembly 200 is configured to lock the hoop 100 to prevent the hoop 100 from sliding relative to the overhead line 20, thereby preventing the damper 30 from sliding relative to the overhead line 20.

The hoop 100 includes a connecting member 110, a first hoop wing 120 and a second hoop wing 130, one end of the connecting member 110 is disposed on the first hoop wing 120, the other end is disposed on the second hoop wing 130, and the first hoop wing 120 and the second hoop wing 130 can be connected into a unified whole by the connecting member 110. The distance between the first hoop wing 120 and the second hoop wing 130 may be varied, and in use, pulling the first hoop wing 120 and the second hoop wing 130 causes a spacing between the first hoop wing 120 and the second hoop wing 130 that is greater than the wire diameter of the overhead wire 20, so as to facilitate the hoop 100 to be looped over the overhead wire 20 via the spacing.

Further, the connecting piece 110, the first hoop wing 120 and/or the second hoop wing 130 have elasticity, so that on one hand, an operator can conveniently pull the first hoop wing 120 and the second hoop wing 130 to generate a distance between the first hoop wing 120 and the second hoop wing 130 larger than the wire diameter of the overhead wire 20, and on the other hand, after the operator stops pulling the first hoop wing 120 and the second hoop wing 130, the hoop 100 can automatically reset to prevent the hoop 100 from falling off from the overhead wire 20. In the present embodiment, the connection member 110, the first cuff wing 120 and the second cuff wing 130 have elasticity, and the connection member 110, the first cuff wing 120 and the second cuff wing 130 are integrally formed. Of course, in other embodiments, only one or two of the connector 110, the first cuff wing 120 and the second cuff wing 130 may have elasticity, and the connector 110, the first cuff wing 120 and the second cuff wing 130 may be manufactured separately and then connected.

Further, a space exists between an end of the first hoop wing 120 away from the connector 110 and an end of the second hoop wing 130 away from the connector 110, and a worker can extend his or her hand into the space to facilitate pulling the first hoop wing 120 and the second hoop wing 130. Of course, in other embodiments, the spacing may be omitted.

In the present embodiment, the connecting member 110 is curved in an arc shape, the first hoop wing 120 is flat, and the second hoop wing 130 is curved in an arc shape. Of course, in other embodiments, the shape of the anchor ear 100 may be flexibly set, for example, the first hoop wing 120 and the second hoop wing 130 are both block-shaped.

In the present embodiment, since the second hoop wing 130 has an arc-shaped plate shape, the end of the second hoop wing 130 away from the connector 110 is tilted, such that a space exists between the end of the first hoop wing 120 away from the connector 110 and the end of the second hoop wing 130 away from the connector 110. Of course, in other embodiments, a space may exist between the end of the first cuff wing 120 distal from the connector 110 and the end of the second cuff wing 130 distal from the connector 110 by removing a portion of the material on the end of the first cuff wing 120 distal from the connector 110 and/or removing a portion of the material on the end of the second cuff wing 130 distal from the connector 110.

The locking assembly 200 includes a penetrating rod 210, a first locking member 220 and a second locking member 230, the first hoop wing 120 is provided with a first through hole, the second hoop wing 130 is provided with a second through hole, and the penetrating rod 210 is penetrated in the first through hole and the second through hole. The first locking member 220 is detachably disposed on the through rod 210, and the first locking member 220 is located on a side of the first hoop wing 120 facing away from the second hoop wing 130. The second locking member 230 includes a rotating wheel 231, where the rotating wheel 231 is rotatably disposed on the through rod 210, and the rotating wheel 231 is a cam or eccentric, and the rotating wheel 231 is located on a side of the second hoop wing 130 opposite to the first hoop wing 120. The wheel 231 can drive the second hoop wing 130 to approach the first hoop wing 120.

In use, the first locking member 220 is separated from the penetrating rod 210, the 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 positioned at one side of the second hoop wing 130 away from the first hoop wing 120. The first locking member 220 is disposed on the through-rod 210 such that the first locking member 220 is located on a side of the first cuff wing 120 remote from the second cuff wing 130.

The rotating wheel 231 is rotated, and since the rotating wheel 231 is a cam or eccentric wheel, the rotating wheel 231 can drive the second hoop wing 130 to approach the first hoop wing 120 so as to lock the hoop 100, so that the hoop 100 hoops the overhead line 20, and the hoop 100 is prevented from moving relative to the overhead line 20. It should be noted that, in the present embodiment, the second hoop wing 130 is far away from the first hoop wing 120 under the action of elastic force when the locking assembly 200 is disassembled. Since the anchor ear 100 is abutted against the damper 30 and the anchor ear 100 is positioned on the side of the damper 30 away from the tower, the anchor ear 100 for tightening the overhead wire 20 can prevent the damper 30 from slipping, thereby preventing fatigue failure of the overhead wire 20.

It should be noted that, as long as a space exists between the end of the first hoop wing 120 far from the connecting piece 110 and the end of the second hoop wing 130 far from the connecting piece 110 before the second hoop wing 130 is driven by the rotating wheel 231 to approach the first hoop wing 120, an operator can conveniently extend a hand into the space, so as to conveniently pull the first hoop wing 120 and the second hoop wing 130. The spacing may decrease or even disappear as the wheel 231 moves the second hoop wing 130 closer to the first hoop wing 120.

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 210. The first locking member 220 can be unscrewed from the penetrating rod 210, so as to facilitate the penetrating rod 210 to penetrate into the first through hole and the second through hole. When the first locking member 220 is screwed on the penetrating rod 210, a certain limiting effect can be achieved on the penetrating rod 210, so as to prevent the penetrating rod 210 from being separated from the anchor ear 100 along the direction from the first through hole to the second through hole. It will be appreciated that the flat design of the first tie wing 120 improves 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 penetrating rod 210 is provided with a pin hole, and the pin is inserted into the pin hole. The pin may be pulled away from the through-rod 210, so that the through-rod 210 may be disposed in 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 penetrating rod 210, so that the penetrating rod 210 is prevented from being separated from the anchor ear 100 along the direction from the first through hole to the second through hole. The number of pin holes may be at least two, and the at least two pin holes are distributed along the length direction of the penetration rod 210. The degree of locking of the anchor ear 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 240, a first shaft hole is formed in the penetrating rod 210, a second shaft hole is formed in the rotating wheel 231, and the rotating shaft 240 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 penetrating rod 210. Of course, in other embodiments, the rotating shaft 240 may be disposed on the penetrating rod 210, and the rotating wheel 231 may be rotatably disposed on the rotating shaft 240. Alternatively, the rotating shaft 240 may be disposed on the rotating wheel 231, and the rotating shaft 240 may be rotatably disposed on the through rod 210, so long as the rotating wheel 231 can rotate relative to the through rod 210.

Further, when the penetrating rod 210 is provided with a first shaft hole and the rotating wheel 231 is provided with a second shaft hole, the anti-sliding device 10 further includes a first limiting block 251 and a second limiting block 252, the first limiting block 251 is disposed on the rotating shaft 240, the second limiting block 252 is detachably disposed on the rotating shaft 240, and the penetrating rod 210 and the rotating wheel 231 are both disposed between the first limiting block 251 and the second limiting block 252. The first and second stoppers 251 and 252 can prevent the penetrating rod 210 and the rotating wheel 231 from being far away from each other along the length direction of the rotating shaft 240. Of course, in other embodiments, the first limiting block 251 and the second limiting block 252 can be omitted.

In this embodiment, the first limiting block 251 is a nut, the rotating shaft 240 and the first limiting block 251 are combined to form a bolt, and the second limiting block 252 is a nut. Of course, in other embodiments, the first limiting block 251 and the second limiting block 252 may be nuts, and the rotating shaft 240 is a double-ended screw.

Referring to fig. 2 and 4, the locking assembly 200 further includes a fixing pad 260, the fixing pad 260 is located between the second hoop wing 130 and the rotating wheel 231, and a first cambered surface 261 is formed on the fixing pad 260, and the first cambered surface 261 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 260 may be omitted.

Referring to fig. 5, in another embodiment, a locking groove 262 is formed on the first cambered surface 261, and a locking block 232 is disposed on the peripheral wall of the rotating wheel 231, wherein the locking block 232 can extend into the locking groove 262 to prevent the rotating wheel 231 from continuing to rotate to a certain extent. When the hoop 100 is locked, the rotating wheel 231 is rotated until the locking block 232 extends into the locking groove 262, and the rotating wheel 231 stops to continue rotating. When the locking assembly 200 is removed, the rotating wheel 231 is rotated in the opposite direction.

Specifically, in another embodiment, the fixing pad 260 may have a substantially cylindrical shape, the locking groove 262 may have a bar-shaped groove, and the locking block 232 may have a bar-shaped shape. Of course, in other embodiments, the shapes of the locking groove 262 and the locking block 232 can be flexibly designed. Alternatively, the locking groove 262 and the locking block 232 may be omitted.

Referring to fig. 2 and 6, in the present embodiment, a second arc surface 263 is formed on the fixing pad 260, and the second arc surface 263 is located at a side of the first arc surface 261 away from the rotating wheel 231. The first cambered surface 261 and the second cambered surface 263 exist simultaneously, so that the fixing pad 260 is in an arc plate shape, and compared with the fixing pad 260 in the other embodiment, the thickness of the fixing pad 260 in the embodiment is relatively thinner, and the material can be effectively saved. Of course, in other embodiments, the shape of the mounting pad 260 can be flexibly designed.

The anti-slip device 10 may further include first elastic members (not shown) that are respectively sleeved on the through rod 210, and the first elastic members are located between the first locking member 220 and the first hoop wing 120. The first elastic member may play a role of buffering, preventing the first locking member 220 from loosening, etc. The first elastic piece can be a pressure spring or a spring pad and the like. In this embodiment, the first elastic member is omitted.

The anti-slip device 10 may further include a second elastic member (not shown) sleeved on the rod 210, and the second elastic member is located between the fixing pad 260 and the second cuff wing 130. The second elastic member may play a role in buffering, and after the rotating wheel 231 drives the second hoop wing 130 to approach the first hoop wing 120, the second elastic member may also play a role in compressing the rotating wheel 231, so as to prevent the rotating wheel 231 from rotating to a certain extent. The second elastic piece can be a pressure spring or a spring pad, etc. In this embodiment, the second elastic member is omitted.

The anti-slip device 10 further includes an anti-slip pad (not shown) disposed on the connecting member 110, the connecting member 110 being adapted to be attached to the overhead line 20, the anti-slip pad being located on a side of the connecting member 110 adapted to be attached to the overhead line 20. The presence of the anti-slip pad increases the friction between the connector 110 and the overhead wire 20 to further prevent slippage of the anchor ear 100 relative to the overhead wire 20 and thus prevent slippage of the damper 30. The non-slip mat may be a plastic mat or a rubber mat having flexibility, etc.

The connecting member 110 includes a third cambered surface 111, and the third cambered surface 111 can improve the adaptability of the connecting member 110 to the appearance of the overhead wire 20, so that the hoop 100 can hoop the overhead wire 20. It will be appreciated that in this embodiment, the cleat is disposed on the third cambered surface 111. The connecting piece 110 further includes a fourth arc surface 112, the third arc surface 111 is located in a space surrounded by the fourth arc surface 112, and the existence of the fourth arc surface 112 can prevent the operator from being scratched by sharp corners.

The second locker 230 further includes a handle 233, and the handle 233 is provided on the rotation wheel 231 so as to rotate the rotation wheel 231 through the handle 233. In the present embodiment, when the length direction of the handle 233 is the same as the length direction of the penetrating bar 210, the distance between the end of the first hoop wing 120 away from the connecting member 110 and the end of the second hoop wing 130 away from the connecting member 110 is the largest. When the anchor 100 is locked, the length direction of the handle 233 intersects the length direction of the rod 210. In this embodiment, the handle 233 in combination with the wheel 231 may form a quick release handle.

The handle 233 includes a fifth arcuate surface 234, and the fifth arcuate surface 234 is configured to engage the fourth arcuate surface 112. In this embodiment, when the locking block 232 extends into the locking groove 262, the fifth cambered surface 234 is attached to the fourth cambered surface 112. The design that the fifth cambered surface 234 is attached to the fourth cambered surface 112 can reduce the space occupied by the anti-sliding device 10 on one hand, and can prevent the handle 233 from rotating under the action of other foreign objects to a certain extent on the other hand.

The above-described anti-slip device 10 has at least the following advantages:

in use, the locking assembly 200 is detached from the anchor ear 100, and the first hoop wing 120 and the second hoop wing 130 are pulled to generate a distance between the first hoop wing 120 and the second hoop wing 130 greater than the wire diameter of the overhead wire 20, so that the anchor ear 100 is looped on the overhead wire 20 via the distance. After the anchor ear 100 is looped on the overhead line 20, the anchor ear 100 is abutted against the damper 30, and the anchor ear 100 is located at a side of the damper 30 away from the tower.

The first locking member 220 is separated from the penetrating rod 210, the rotating wheel 231 is rotatably disposed on the penetrating rod 210, and the fixing pad 260 and the second elastic member are sleeved on the penetrating rod 210, so that the fixing pad 260 is located between the rotating wheel 231 and the second elastic member. The penetrating rod 210 is penetrated through the first through hole and the second through hole, so that the rotating wheel 231, the fixing pad 260 and the second elastic member are all positioned at one side of the second hoop wing 130 away from the first hoop wing 120.

The first elastic member is sleeved on the penetrating rod 210, and the first locking member 220 is disposed on the penetrating rod 210, so that the first elastic member is located between the first locking member 220 and the first hoop wing 120. 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 through 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 through rod 210. The handle 233 is turned to make the locking block 232 extend into the locking groove 262, and the fifth cambered surface 234 is attached to the fourth cambered surface 112.

Because the rotating wheel 231 is a cam or eccentric wheel, the rotating wheel 231 can drive the second hoop wing 130 to approach the first hoop wing 120 so as to lock the hoop 100, so that the hoop 100 hoops the overhead line 20, and the hoop 100 is prevented from moving relative to the overhead line 20. Since the anchor ear 100 is abutted against the damper 30 and the anchor ear 100 is positioned on the side of the damper 30 away from the tower, the anchor ear 100 for tightening the overhead wire 20 can prevent the damper 30 from slipping, thereby preventing fatigue failure of the overhead wire 20. The anti-slip device 10 may be disposed on the overhead line 20 provided with the damper 30, and the damper 30 may not be detached.

When the locking assembly 200 is detached from the hoop 100, the handle 233 can be reversely rotated, and the second hoop wing 130 is far away from the first hoop wing 120 under the action of elastic force, so that the first locking member 220 is separated from the penetrating rod 210. Pulling on the first hoop wing 120 and the second hoop wing 130 creates a spacing between the first hoop wing 120 and the second hoop wing 130 that is greater than the wire diameter of the overhead wire 20 to facilitate removal of the hoop 100 from the overhead wire 20 via the spacing.

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. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
