Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude wires, in particular to a wire clamping assembly. Background Art

[0002] Wire clamp assemblies are often used to suspend and fix devices or products on wires.

[0003] For example, the ground wire deicing robot in the prior art can be fixed to the wire through a wire clamping assembly, which can prevent the deicing robot from falling and being damaged when a large amount of ice cubes fall and cause wire jumps.

[0004] It can also be used to hang equipment on the conductor to monitor the conductor condition or to drive away birds flying on the conductor.

[0005] In order to enable the clamping assembly to automatically clamp onto the conductor after being hoisted from a high altitude by tools such as drones or cranes, most existing clamping assemblies adopt the form of a quick-hanging buckle as described in the text of a quick-hanging buckle with the Chinese patent publication number CN215381876U. When the quick-hanging buckle is clamped, the baffle of the quick-hanging buckle opening is pushed inward by the wire, and after the wire enters the holding cavity of the quick-hanging buckle, the baffle is reset under the action of the torsion spring to block the quick-hanging buckle opening. Obviously, in order for the baffle to be able to reset outward stably during the holding process, a sufficient space for the baffle to reset is required between the holding cavity of the quick-hanging buckle and the guide. This results in poor fit between the quick-hanging buckle and the wire, and there is a problem of severe shaking of the clamping assembly after clamping, which urgently needs to be solved. Utility Model Content

[0006] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a wire clamping assembly, which can ensure a stable fit between the clamping assembly and the wire, thereby ensuring the stability of the clamping of the clamping assembly on the wire.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A wire clamping assembly includes a first cylindrical seat and a second cylindrical seat whose inner ends are fixed to each other and combined to form a V-shaped structure, and also includes a third cylindrical seat that is elastically driven by an elastic driving assembly installed on the first cylindrical seat and can elastically slide along its own axial direction. During the elastic sliding process, the third cylindrical seat has an initial state of being misaligned with the opening of the V-shaped structure, and a clamping state in which it is jointly enclosed with the first cylindrical seat and the second cylindrical seat to form a triangular clamping cavity; the initial state is locked by a unlocking mechanism, and the unlocking mechanism has an operating part located at the opening of the V-shaped structure, and the operating part is driven by the wire entering the opening of the V-shaped structure to unlock the initial state. Thereafter, the driving part of the elastic driving assembly drives the third cylindrical seat to slide to form the clamping state.

[0009] As a further solution of the present invention: the unlocking mechanism includes a baffle rod located at the opening of the V-shaped structure, and the two ends of the baffle rod are respectively abutted against the third cylindrical seat and the second cylindrical seat to prevent the third cylindrical seat from elastically sliding toward the opening of the V-shaped structure, and the operating part is constituted by the rod body of the baffle rod.

[0010] As a further solution of the present invention: the unlocking mechanism includes an unlocking lever that is rotatably engaged with the second cylindrical seat through a fulcrum pin, the fulcrum pin is distributed parallel to the wire, and the first end of the unlocking lever is fixed with a limit pin that forms a lock with the driving part to lock the initial state, and the second end of the unlocking lever is located at the opening of the V-shaped structure. The second end of the unlocking lever can be pushed by the wire entering the opening of the V-shaped structure, and the limit pin of the unlocking lever belt is rotated to unlock the driving part to unlock the initial state. The second end of the unlocking lever constitutes the operating part.

[0011] As a further solution of the present invention: a connecting socket for inserting the fulcrum pin is provided on the second cylindrical seat, and the aperture of the connecting socket is larger than the outer diameter of the fulcrum pin, so that when the unlocking lever is rotated to unlock, the fulcrum pin slides and separates from the connecting socket.

[0012] As a further solution of the present invention: the elastic driving assembly includes a slide seat fixed to the second cylindrical seat, a slide bar slidably fitted on the slide seat and a slider slidably fitted on the slide bar, the slider is fixed to the third cylindrical seat, and the driving part is composed of the slider. A tension spring is installed on the slide seat to drive the slide seat to elastically contract into the slide seat. In the initial state, the slider is located at the outer end of the slide bar that slides and expands, and the inner end of the slide bar is provided with an abutment portion so that after being unlocked in the initial state, the inner end of the slide bar can abut against the slider and slide to the inner end of the slide seat together with the slider.

[0013] As a further solution of the present invention: a rubber sleeve is provided on the outer periphery of the cylindrical seat at the clamping cavity.

[0014] As a further solution of the present invention: a fluorescent sticker is provided on the rubber sleeve.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The clamping process of the clamping assembly can be operated by a crane or drone. The wire de-icing and unlocking mechanism during the clamping process can switch the clamping assembly from the initial state to the clamping state, thereby realizing the clamping operation of the clamping assembly on the wire. There is no need to climb onto the wire, ensuring the safety of the clamping of the clamping assembly. In addition, among the three cylindrical seats that make up the clamping assembly, the third cylindrical seat slides along its own axis and blocks the opening of the V-shaped structure. Compared with the third cylindrical seat that rotates to block the opening of the V-shaped structure, it not only ensures that all three cylindrical seats can achieve stable fit with the wire, but also prevents the third cylindrical seat from loosening when subjected to the radial force generated by the cable. Combined with the three cylindrical seats, a stable triangular frame structure is formed, which effectively guarantees the stability of the clamping assembly on the wire.

[0017] 2. The unlocking mechanism in the initial locking state adopts a labor-saving lever structure formed by the unlocking lever, and during the unlocking process, it is only necessary to separate the limit latch downward from the driving part, which has the advantage of labor-saving unlocking in the initial state.

[0018] 3. When the unlocking lever is rotated to unlock, the unlocking lever loses its elastic thrust because the aperture of the connecting socket is larger than the outer diameter of the fulcrum pin. At this time, the fulcrum pin slides and separates from the connecting socket, realizing automatic separation of the unlocking lever and the clamping assembly, preventing the clamping assembly from carrying unnecessary structure in the clamped state, thereby reducing the load-bearing burden of the wire.

[0019] 4. In the elastic drive assembly, the slider can be located at the outer end of the sliding and expanded slide in the initial state. When elastically contracted, the slider can slide to the inner end of the slide seat, so that the sliding stroke of the slider is close to the total length of the slide seat and the slide bar. Compared with directly using a multi-stage telescopic rod as the elastic drive assembly, when the space occupied after contraction is the same, the driving stroke of the elastic drive assembly can be effectively improved.

[0020] 5. A rubber sleeve is installed around the outer periphery of the cylindrical base, within the clamping cavity, effectively increasing the clamping friction between the cylindrical base and the conductor. Furthermore, a fluorescent sticker is attached to the rubber sleeve for nighttime inspection visibility, enabling both manual identification and identification by monitoring probes on the transmission line. The fluorescent stickers on conductors of different phases are different colors, allowing for easy identification. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] For ease of understanding, the specific structure and working mode of the present invention are further described below with reference to the accompanying drawings:

[0032] The specific structure of the utility model refers to Figure 1-8 As shown, its main structure includes a clamping assembly that can be clamped on the wire and an ice-breaking assembly installed on the clamping assembly and used for breaking ice.

[0033] 1. Snap-on components

[0034] like Figure 1-2 As shown, the clamping assembly includes three cylindrical seats 10, which are the first cylindrical seat 10a, the second cylindrical seat 10b and the third cylindrical seat 10c. The inner ends of the first cylindrical seat 10a and the second cylindrical seat 10b are fixed to each other and combined to form a V-shaped structure. The third cylindrical seat 10c is elastically driven by the elastic drive assembly 20 installed on the first cylindrical seat 10a and can elastically slide along its own axis. The third cylindrical seat 10c has the following characteristics during the elastic sliding process: Figure 1 The opening of the V-shaped structure is misaligned in the initial state shown, and Figure 2 The clamping state shown is a triangular clamping cavity formed together with the first cylindrical seat 10a and the second cylindrical seat 10b.

[0035] like Figure 1 As shown, the initial state is locked by the unlocking mechanism 50, and the unlocking mechanism 50 has an operating part located at the opening of the V-shaped structure, and the operating part is driven by the wire abutment entering the opening of the V-shaped structure to unlock the initial state. Thereafter, the driving part of the elastic driving component 20 drives the third cylindrical seat 10c to slide to form a clamping state.

[0036] When using, Figure 8 As shown in the middle A state, the initial state of the clamping assembly can be hoisted by a drone or a crane at the intersection of the V-shaped structure so that the opening of the V-shaped structure faces downward, and the opening of the V-shaped structure is hoisted to the top of the wire. Thereafter, the V-shaped structure is hoisted downward so that the opening of the V-shaped structure is placed on the outer periphery of the wire. Figure 8 As shown in the B state, when the wire enters the inner side of the opening of the V-shaped structure, the wire pushes the operating part to unlock the initial state. Figure 8 As shown in the middle C state, the driving part of the elastic driving component 20 drives the third cylindrical seat 10c to slide along its own axis. Finally, as shown in FIG. Figure 8 As shown in the middle D state, the third cylindrical seat 10c, the first cylindrical seat 10a and the second cylindrical seat 10b are together enclosed to form a clamping state of a triangular clamping cavity, thereby completing the clamping and fixing of the clamping assembly on the wire. The clamping process of the clamping assembly can be operated by a crane or a drone, without the need to climb onto the wire, ensuring the safety of the clamping of the clamping assembly. In addition, among the three cylindrical seats 10 that make up the clamping assembly, the third cylindrical seat 10c slides along its own axis and blocks the opening of the V-shaped structure. Compared with the third cylindrical seat 10c, which uses a rotation to block the opening of the V-shaped structure, it not only ensures that the three cylindrical seats 10 can all be stably fitted with the wire, but also ensures that the third cylindrical seat 10c will not loosen when subjected to the radial force generated by the cable; combined with the three cylindrical seats to form a stable triangular frame structure, the stability of the clamping assembly on the wire is effectively guaranteed.

[0037] Specifically, the unlocking mechanism 50 includes a baffle rod (not shown in the figure) located at the opening of the V-shaped structure, and the two ends of the baffle rod are respectively in contact with the third cylindrical seat 10c and the second cylindrical seat 10b to prevent the third cylindrical seat 10c from elastically sliding toward the opening of the V-shaped structure, and the rod body of the baffle rod constitutes the operating part. When the wire enters the inner side of the opening of the V-shaped structure, the contact between the baffle rod and the third cylindrical seat 10c and the second cylindrical seat 10b is loosened, causing the baffle rod to fall, thereby releasing the initial state. In this embodiment, the unlocking mechanism 50 can automatically separate from the clamping assembly after the initial state is released, preventing the clamping assembly from carrying unnecessary structure that affects the ice-breaking effect of the ice-breaking assembly. Since a large thrust is required to push the baffle rod to move in this embodiment, it is suitable for a structure with a large gravity of the clamping assembly. In order to adapt to a structure with a small gravity of the clamping assembly, the unlocking mechanism 50 of the present application also provides the following another embodiment.

[0038] like Figure 1 and Figure 4 As shown, the unlocking mechanism 50 includes an unlocking lever 52 that is pivotally engaged with the second cylindrical seat 10b via a fulcrum pin 51, and the fulcrum pin 51 is arranged parallel to the wire. The first end of the unlocking lever 52 is fixed with a limit pin 53 that forms a lock with the drive unit to lock the initial state. The second end of the unlocking lever 52 is located at the opening of the V-shaped structure. The second end of the unlocking lever 52 can be pushed by the wire entering the opening of the V-shaped structure, causing the limit pin 53 on the unlocking lever 52 to rotate and unlock the drive unit to unlock the initial state. The second end of the unlocking lever 52 constitutes the operating unit. In this embodiment, the unlocking mechanism 50 adopts a labor-saving lever structure formed by the unlocking lever 52. During the unlocking process, the limit pin 53 only needs to be separated downward from the drive unit, which has the advantage of labor-saving unlocking in the initial state. During specific implementation, the second end of the unlocking mechanism 52 located at the opening of the V-shaped structure is preferably inclined toward the inside of the V-shaped structure, so that the wire abuts against the second end after a partial area has entered the inner cavity of the V-shaped structure. Thereafter, the wire abuts against the second end to trigger the unlocking of the initial state, which can stably ensure that the third cylindrical seat 10c enters the clamping cavity inside the V-shaped structure before sliding along its own axis and sealing the opening of the V-shaped structure.

[0039] Furthermore, to ensure that the unlocking lever 52 does not remain on the clamping assembly after unlocking, Figure 4As shown, the second cylindrical seat 10b is provided with a connecting socket 10a1 for inserting the fulcrum pin 51. The aperture of the connecting socket 10a1 is larger than the outer diameter of the fulcrum pin 51. In the initial state, since the unlocking lever 52 is used to lock the driving unit, and since the force is mutual, the driving unit will also generate an elastic thrust on the unlocking lever 52. Under this elastic thrust, the outer wall of the fulcrum pin 51 abuts the inner wall of the connecting socket 10a1, thereby maintaining the unlocking lever 52 in the locked initial state and preventing it from falling. When the unlocking lever 52 rotates to unlock, since the aperture of the connecting socket 10a1 is larger than the outer diameter of the fulcrum pin 51, the unlocked unlocking lever 52 loses its elastic thrust. At this time, the fulcrum pin 51 slides away from the connecting socket 10a1, achieving automatic separation of the unlocking lever 52 from the clamping assembly.

[0040] On the basis of the above, if Figure 3 and Figure 5 As shown, the elastic drive assembly 20 includes a slide 21 fixed to the second cylindrical seat 10b, a slide bar 22 slidably engaged with the slide 21, and a slider 23 slidably engaged with the slide bar 22. The slider 23 constitutes the driving portion. A tension spring 24 is mounted on the slide 21 to drive the slide 21 to elastically retract into the slide 21. In the initial state, the slider 23 is located at the outer end of the slidably extended slide bar 22. The inner end of the slide bar 22 is provided with an abutment portion that abuts the slider 23 and slides together with the slider 23 to the inner end of the slide 21. In this embodiment, the slider 23 is initially located at the outer end of the slidably extended slide bar 22. During elastic contraction, the slider 23 slides to the inner end of the slide 21, resulting in a sliding stroke of the slider 23 that approximates the combined length of the slide 21 and the slide bar 22. Compared to a configuration in which a multi-stage telescopic rod is directly used as the elastic drive assembly 20, the driving stroke of the elastic drive assembly 20 is effectively increased while maintaining the same post-contraction space. In this embodiment, in order to adapt to the embodiment in which the unlocking mechanism 50 adopts the unlocking lever 52 , the outer end of the slide bar 22 has a limiting hole 221 for the limiting pin 53 to be inserted into and lock the slider 23 .

[0041] On the basis of the above, if Figure 1 As shown, a rubber sleeve 40 is installed on the outer periphery of the cylindrical base 10, located in the clamping cavity, effectively increasing the clamping friction between the cylindrical base 10 and the conductor. Furthermore, a fluorescent sticker 41 is installed on the rubber sleeve 40 for nighttime inspection visibility, allowing for both manual identification and identification by monitoring probes on the transmission line. Furthermore, the fluorescent stickers 41 on conductors of different phases are of different colors, allowing for easy identification.

[0042] 2. Ice-breaking components

[0043] like Figure 6As shown, the ice-breaking assembly mainly includes an ice-breaking hammer 14. Specifically, the end of the cylindrical seat 10 is provided with a launch chamber 12 and a combustion chamber 13 connected to each other through an air guide hole 111 in sequence from the outside to the inside. A movable sealing assembly is provided in the air guide hole 111. The ice-breaking hammer 14 is distributed in the launch chamber 12 and can be launched outward along the axial direction of the cylindrical seat 10 to remove ice. A combustible material and an igniter 15 that is remotely activated are provided in the combustion chamber 13, so that the combustible material in the combustion chamber 13 can be remotely ignited and burned to produce high-pressure gas, and the high-pressure gas generates an impact force that pushes the ice-breaking hammer 14 to be launched outward. The ice-breaking assembly in this application is pre-clamped on the wire by a clamping assembly before the wire is covered with ice. After the wire is covered with ice, the igniter 15 of the ice-breaking assembly on the ice-covered cable is remotely activated, and the ice-breaking hammer 14 is launched outward to achieve de-icing. Compared with the traditional method of using de-icing robots for de-icing, the present application does not need to consider the problem of low de-icing efficiency or inability to de-icing caused by the de-icing robot's inability to cross electric poles or spacers, nor is there a problem of de-icing efficiency affected by the de-icing robot's endurance. By pre-intervally connecting multiple ice-breaking components on the conductors, efficient de-icing at multiple stations can be achieved, which has the advantages of high de-icing efficiency and high adaptability to line working conditions.

[0044] In this embodiment, the cylindrical seat 10 can simply serve as a carrier for the ice-breaking assembly, with an existing clamping mechanism, such as a clip, being provided to securely engage the conductor. Furthermore, at least three cylindrical seats 10 can be provided, forming an end-to-end connected frame structure. This frame structure forms a clamping cavity that clamps the conductor.

[0045] In addition, if Figure 6 As shown, the movable sealing assembly includes a one-way valve plug 16 disposed within the air guide hole 111 and slidable toward the firing chamber 12. A sealing ring 17 is disposed on the periphery of the one-way valve plug 16, which seals the air guide hole 111 and provides a stable seal for the air guide hole 111. Furthermore, radial holes 110 are distributed radially along the outer side of the air guide hole 111. Abutment steel columns 18 are disposed within the radial holes 110, driven by a pressure spring 19 and elastically abutting the one-way valve plug 16. This further ensures the stability of the one-way valve plug 16 in the air guide hole 111 in its initial state, preventing the one-way valve plug 16 from falling off and causing the seal at the air guide hole 111 to fail in the initial state. Of course, in actual implementation, the movable sealing assembly can also directly utilize a rubber plug or a wooden plug.

[0046] 3. Combination of snap-on components and ice-breaking components

[0047] like Figure 1 and Figure 2As shown, at least three cylindrical seats 10 are provided, and a connecting seat 30 is used between the at least three cylindrical seats 10 to form a frame structure connected end to end. This frame structure forms a clamping cavity that clamps the outer circumference of the wire. The connecting seat 30 includes a fixing portion and a latch assembly that plugs and locks the fixing portion with the cylindrical seat 10. The plug-in connection between the latch assembly and the cylindrical seat 10 is connected to the firing cavity 12. The high-pressure gas flowing into the firing cavity 12 and the ice-breaking hammer 14 drive the latch assembly to slide outward and unlock, thereby disassembling the frame structure. In this embodiment, the ice-breaking assembly cooperates with the clamping assembly, so that the clamping assembly can be disassembled after the ice-breaking operation is completed, eliminating the need to remove the clamping assembly and ice-breaking assembly from the cable.

[0048] Specifically, such as Figure 1 、 Figure 2 and Figure 5-7 As shown, the fixing portion of the connecting seat 30 is a C-shaped ring 31, the inner cavity of the C-shaped ring 31 can be set on the outer periphery of the cylindrical seat 10, and the inner cavity of the C-shaped ring 31 can be used in conjunction with the pin assembly to achieve fixation with the cylindrical seat 10. Figure 6 As shown, the latch assembly includes two T-shaped outer pins 32, one on each side of a C-shaped ring 31. The T-shaped heads of the T-shaped outer pins 32 are elastically driven by a compression spring 33 and inserted into a pin hole 11 in the side wall of the cylindrical seat 10. A T-shaped pusher 34 is also provided in the pin hole 11, the outer end of which abuts the head of the T-shaped outer pin 32 and the inner end of which extends into the firing chamber 12. The inner end of the T-shaped pusher 34 is located in the firing path of the ice-breaking hammer 14, and the ice-breaking hammer 14 can engage with the inner end of the T-shaped pusher 34. When high-pressure gas flows into the firing chamber 12 and drives the ice-breaking hammer 14 to fire, the ice-breaking hammer 14 generates a thrust that drives the T-shaped pusher 34 to slide outward. At the same time, some of the high-pressure gas enters the pin hole 11, assisting the outward sliding of the T-shaped pusher 34, thereby separating the T-shaped outer pin 32 from the cylindrical seat 10. This unlocks the C-shaped ring 31 and the cylindrical seat 10, causing the cylindrical seat 10 to disassemble.

[0049] On the basis of the above, if Figure 6 As shown, the outer end of the ice-breaking hammer 14 is tapered, ensuring the impact effect when the ice-breaking hammer 14 is launched outward. In addition, the inner end of the T-shaped push head 34 abuts against the tapered surface of the ice-breaking hammer 14, forming an oblique wedge fit between the tapered surface and the T-shaped push head 34. This elastically locks the ice-breaking hammer 14 in the launch chamber 12 before the ice-breaking hammer 14 is launched, thereby preventing the ice-breaking hammer 14 from falling out of the launch chamber 12 when the cylindrical base 10 is inverted.

[0050] Further, such as Figure 1 and Figure 3As shown, when the connecting seat 30 is used in conjunction with the elastic drive assembly 20, taking an embodiment in which three cylindrical seats 10 are set as an example, the three cylindrical seats 10 include a first cylindrical seat 10a, a second cylindrical seat 10b and a third cylindrical seat 10c, and the connecting seat 30 includes a first connecting seat 30a and a second connecting seat 30b; wherein, the inner ends of the first cylindrical seat 10a and the second cylindrical seat 10b are fixed to each other through the first connecting seat 30a and combined to form a V-shaped structure, the elastic drive assembly 20 is installed on the first cylindrical seat 10a, and the driving part of the elastic drive assembly 20 is fixed to the third cylindrical seat 10c through the second connecting seat 30b.

[0051] It is worth mentioning that in actual implementation, the number of ice-breaking assemblies can be determined according to the ice coverage on the conductors in the corresponding area each year. For example, in areas where the thickness of ice covering the conductors is relatively small all year round, the number of ice-breaking assemblies can be reduced, that is, there is no need to set an ice-breaking hammer 14 at the end of each cylindrical seat 10. For cylindrical seats 10 without ice-breaking hammers 14, the structure of the connecting seat 30 can be adaptively adjusted; taking the connection between the inner ends of the first cylindrical seat 10a and the second cylindrical seat 10b as an example, Figure 1 As shown, the inner end of the first cylindrical seat 10a is not provided with an ice-breaking hammer 14, but the inner end of the second cylindrical seat 10b is provided with an ice-breaking hammer 14. The connection between the first connecting seat 30a and the second cylindrical seat 10b is provided with a C-shaped ring 31, and the connection with the first cylindrical seat 10a can be directly fixed with bolts. Of course, if the inner ends of both the first cylindrical seat 10a and the second cylindrical seat 10b are provided with ice-breaking hammers 14, the first connecting seat 30a needs to be provided with two C-shaped rings 31 fixed to each other.

[0052] Of course, it will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, but also encompasses the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and it is intended that all variations that fall within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.

[0053] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
