Description

Technical Field

[0001] This utility model relates to the technical field of overhead transmission lines, and in particular to a device for fixing insulated conductors without binding. Background Technology

[0002] In the field of power engineering, securing insulated conductors is a crucial step in ensuring the safe and stable operation of transmission lines. Traditional securing methods rely heavily on binding techniques, which have several shortcomings. For example, manual binding requires segment-by-segment operation, which is time-consuming and labor-intensive. Especially in complex lines or high-altitude operations, the construction is difficult and time-consuming. At the same time, binding methods cannot cope with the changing natural environment. In extreme weather conditions such as strong winds and hail, the binding tape is easily damaged, leading to the conductor falling off.

[0003] To address the shortcomings of traditional processes in terms of construction efficiency, safety, and durability, existing technologies have proposed a snap-on wire clamp to fix the wires, thereby improving reliability and convenience.

[0004] However, existing wire clamps have limited versatility. When dealing with wires of different diameters, it is often necessary to adjust the structure or change the model, resulting in reduced construction efficiency and increased maintenance costs. Furthermore, operators need to be equipped with the appropriate tools to install the wire clamps. Specifically, when the wire diameter is smaller than the design range of the wire clamp, there will be problems with secure fixing. In this case, operators need to add padding to the gap between the wire clamp and the wire to enhance the firmness, which is time-consuming and laborious. Conversely, when the wire diameter is too large, excessive clamping force causes uneven mechanical stress, which can easily lead to wire wear or even breakage over long-term operation. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art, such as poor versatility of wire clamps, the need for adjustment or replacement to cope with wires of different diameters, high operational difficulty, and reduced reliability.

[0006] To achieve the above objectives, this application proposes a binding-free insulated wire fixing device, comprising:

[0007] Circular mounting section;

[0008] The pressure plate is provided on the top of the annular mounting part. The top surface of the pressure plate is provided with a first groove for supporting the end face of the wire. The two sides of the first groove are respectively provided with through holes and limiting grooves along the vertical direction.

[0009] A pressure cap is provided on the top surface of the pressure plate, and a second groove is provided on the bottom surface of the pressure cap. The second groove cooperates with the first groove to form a clamping structure for clamping the surface of the wire.

[0010] A connecting assembly for connecting the pressure plate and the pressure cap, the connecting assembly comprising:

[0011] A threaded sleeve is provided inside the through hole;

[0012] The first stud is screwed into the threaded sleeve and hinged to one end of the pressure cap;

[0013] The second stud is arranged on the opposite side of the first stud. The second stud is welded to the bottom surface of the pressure cap and snapped into the limiting groove. Its end is provided with a nut for locking the installation position.

[0014] This application addresses the problem of wire clamps having poor versatility, requiring adjustment or replacement for wires of different diameters, leading to decreased maintenance efficiency, increased costs, and reduced reliability in existing technologies. A first stud is screwed into the threaded sleeve at the height of one end of the clamp, which is adjusted by the depth of the screw into the threaded sleeve. The connection assembly includes a threaded sleeve embedded in the through hole of the wire clamp to provide stable support, and a second stud is welded to the clamp on the opposite side and engaged in the limiting groove. The end nut provides mechanical locking. These three components work together to achieve dynamic adjustment and rigid fixation, solving the problem of poor universality of wire clamps in existing technologies, requiring adjustment or replacement for different wire diameters, resulting in decreased maintenance efficiency, increased costs, and reduced reliability.

[0015] Furthermore, to enhance the stability of the wire clamping, the number of the wire clamping plates is two and they are symmetrically arranged on the annular mounting part.

[0016] Furthermore, to avoid damage to the surface of the wire during clamping, the end face of the second groove that contacts the wire is covered with a wear-resistant polyurethane liner.

[0017] Furthermore, in order to achieve tool-free clamping, the nut is configured as a wing nut, which can be manually tightened directly through the wing-shaped structure of the wing nut, and cooperates with the threaded section of the second stud to form a tool-free locking mechanism.

[0018] Furthermore, in order to suppress the loosening of the nut caused by vibration, an anti-loosening pad is provided inside the wing nut.

[0019] Furthermore, in order to form a closed clamping structure by the main and auxiliary clamping frames circumferentially enclosing each other, the annular mounting part includes: a main clamping frame, an auxiliary clamping frame that circumferentially encloses the main clamping frame; a main mounting platform disposed at the clamping end of the main clamping frame; an auxiliary mounting platform disposed at the clamping end of the auxiliary clamping frame; and a quick-connect mechanism connecting the main mounting platform and the auxiliary mounting platform.

[0020] Furthermore, to enable tool-free installation of the clamping frame onto the insulator, the quick-connect mechanism includes: a sleeve embedded in the main mounting platform, the inner cavity of the sleeve being configured as a tapered cavity tapering towards the secondary mounting platform; a cylindrical connector inserted into the narrow opening of the tapered cavity; ball bearings embedded in the cylindrical connector and arranged circumferentially; a compression spring disposed between the cylindrical connector and the bottom surface of the inner wall of the sleeve; and a connecting rod connecting the main mounting platform and the secondary mounting platform and passing through the cylindrical connector and the tapered cavity.

[0021] The beneficial effects of this application are as follows:

[0022] 1. This application provides a wire clamping plate on the annular mounting part, with the first groove of the wire clamping plate and the second groove of the clamping cap forming an adaptive clamping structure. In the connecting assembly, a threaded sleeve is embedded in the through hole of the wire clamping plate to provide stable support. The first stud adjusts the height of one end of the clamping cap by the depth of screwing into the threaded sleeve, adapting to different wire diameters. The second stud is welded to the clamping cap on the opposite side and snapped into the limiting groove, with the end nut forming a mechanical lock. The three components work together to achieve dynamic adjustment and rigid fixation, solving the problem in the prior art where the wire clamp has poor versatility, requiring adjustment or replacement for wires of different diameters, leading to decreased maintenance efficiency, increased costs, and reduced reliability.

[0023] 2. This application configures the nut on the second stud as a wing nut, and provides a tool-free locking mechanism between the annular mounting parts. The two work together to install the fixing device on the insulator without the use of tools, while simultaneously clamping the conductor.

[0024] 3. The binding-free insulated wire fixing device of this application has a uniform structure and can clamp wires of different diameters through fine adjustment, thus improving the versatility of the binding-free insulated wire fixing device. It can be processed with a set of molds during production, reducing mold opening costs. At the same time, the installation process of the universal binding-free insulated wire fixing device is uniform, which is easy to operate and reduces the difficulty of installation for operators.

[0034] The following will be combined with the appendix Figures 1-3 The embodiments of the technical solutions of this application are described in detail below. The following embodiments are only used to more clearly illustrate the technical solutions of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0035] Example 1

[0036] like Figures 1-2 This illustration depicts a binding-free insulated wire fixing device according to this application. To address the issue of clamping wires of different diameters through an adaptive clamping structure, this embodiment includes an annular mounting portion 1 with two symmetrically arranged pressure plates 2 on its top. Each pressure plate 2 has a first groove 21 on its top surface and through holes 22 and limiting grooves 23 on its sides. A second groove 31 is provided on the bottom surface of the pressure cap 3, forming a clamping cavity with the first groove 21. In the connecting assembly 4, a threaded sleeve 41 is embedded in the through hole 22, a first stud 42 is screwed into the threaded sleeve 41 and hinged to one end of the pressure cap 3, and a second stud 43 is welded to the bottom surface of the pressure cap 3 and engaged in the limiting groove 23, with its end locked by a wing nut 44a.

[0037] Specifically, the annular mounting part 1 is formed by the main clamping frame 11 and the auxiliary clamping frame 12 encircling each other. The two are connected to the insulator by the quick-connect mechanism 15 to form support for the pressure plate 2. At the same time, the pressure plate 2 and the pressure cap 3 cooperate to clamp the conductor. The first groove 21 on the top surface of the pressure plate 2 and the second groove 31 on the bottom surface of the pressure cap 3 form an encirclement of the conductor.

[0038] A connecting component 4 is provided between the clamping plate 2 and the clamping cap 3 to adjust the gap between the first groove 21 and the second groove 31, thereby clamping wires of different diameters. One end of the first stud 42 is hinged to the bottom of the clamping cap 3, allowing the clamping cap 3 to rotate around the hinge point. When placing the wire, the clamping cap 3 can be rotated first to make room for the first groove 21, preventing interference between the clamping cap 3 and the wire.

[0039] The other end of the first stud 42 is screwed into the threaded sleeve 41. By rotating the first stud 42, the height of the first stud 42 protruding from the top surface of the pressure plate 2 can be changed, thereby changing the gap between the pressure cap 3 and one side of the pressure plate 2. When the wire diameter changes, rotating the first stud 42 adjusts the height of one end of the pressure cap 3, so that the radial dimension of the clamping cavity formed by the second groove 31 and the first groove 21 adapts to the wire diameter. After the height adjustment is completed, the pressure cap 3 is rotated to a position parallel to the pressure plate 2. At this time, the second stud 43 contacts the limiting groove 23. Then, the nut 44 on the second stud 43 is rotated so that the top surface of the nut 44 contacts the bottom surface of the pressure plate 2. The clamping and locking are completed by the friction between the nut 44 and the pressure plate 2.

[0040] Furthermore, the end face of the second groove 31 that contacts the wire is covered with a wear-resistant polyurethane liner 32 to further enhance the friction between the second groove 31 and the contact surface of the wire, thereby enhancing the clamping stability.

[0041] Example 2: Quick-locking mechanism without tool installation

[0042] like Figures 1-2 This application illustrates a binding-free insulated wire fixing device. To simplify the installation process and allow operators to fix the wire without tools, the annular mounting part 1 of this application is composed of a main clamping frame 11 and a secondary clamping frame 12 that are encircled together. The two are connected by a quick-connect mechanism 15. Operators can connect the two halves of the annular mounting part 1 through the quick-connect mechanism 15 without carrying tools, so that it is clamped on the insulator and the installation is completed.

[0043] Specifically, the sleeve 151 is embedded in the main mounting platform 13, and its inner cavity is a tapered cavity 152 that tapers towards the auxiliary mounting platform 14, with a taper ratio of 1:10 to ensure self-locking stability. The cylindrical connector 153 is inserted into the narrow end of the tapered cavity 152, and ball bearings 154 are embedded in its outer circumference. The diameter of the ball bearings matches the taper of the tapered cavity 152. The compression spring 155 is located between the cylindrical connector 153 and the bottom surface of the inner wall of the sleeve 151, and the initial compression is set to 30% of the total length of the spring. The connecting rod 156 passes through the main and auxiliary mounting platforms and is axially fixed, with an M8 thread at the end to match the insulator mounting hole.

[0044] Working principle:

[0045] The annular mounting part 1 is formed by the main clamping frame 11 and the auxiliary clamping frame 12 encircling each other. The two are connected to the insulator by the quick-connect mechanism 15 to form support for the pressure plate 2. The specific operation is as follows: push the sleeve 151 to move towards the main mounting platform 13, the compression spring 155 is further squeezed, the gap between the sleeve 151 and the conical cavity 152 is widened, at this time the ball 154 is freed from the constraint of the inner wall of the conical cavity 152 and can roll freely along the circumference of the joint 153. There is no frictional resistance when inserting the connecting rod 156.

[0046] Furthermore, the secondary clamping frame 12 embraces the main clamping frame 11. At this time, the connecting rod 156 passes through the hole of the secondary mounting platform 14. After the annular mounting part 1 is installed on the insulator, the sleeve 151 is released, and the compression spring 155 restores its deformation, pushing the cylindrical connector 153 to move along the conical cavity 152. The ball bearing 154 generates radial displacement under the pressure of the conical surface, forming an interference fit with the hole wall of the secondary mounting platform 14. During this period, the orientation of the first groove 21 on the wire clamping plate 2 can be adjusted by locking and unlocking the fast connection mechanism 15 until it is the same as the direction of the conductor arrangement, thus completing the final installation of the secondary clamping frame 12 embracing the main clamping frame 11.

[0047] For the wire clamping part, the top surface of the pressure plate 2 has a first groove 21, and the bottom surface of the pressure cap 3 has a second groove 31, which together form a clamping cavity. In the connecting assembly 4, the threaded sleeve 41 is embedded in the through hole 22 of the pressure plate 2, and the first stud 42 is screwed into the threaded sleeve 41 and hinged to one end of the pressure cap 3, so that the pressure cap 3 can rotate to avoid interference with the wire when placing it. Rotating the first stud 42 can change its height protruding from the top surface of the pressure plate 2, thereby adjusting the gap between the pressure cap 3 and one side of the pressure plate 2, so that the clamping cavity diameter... The device adapts to wires of different diameters. The second stud 43 is welded to the bottom surface of the pressure cap 3 and snapped into the limiting groove 23 of the pressure plate 2. The end is locked by a wing nut 44a. After the height is adjusted, the pressure cap 3 is rotated to be parallel to the pressure plate 2. The nut 44 on the second stud 43 is rotated so that its top surface contacts the bottom surface of the pressure plate 2. The clamping and locking are completed by friction. The nut 44 includes a wing nut 44a and an anti-loosening pad 44b. The anti-loosening pad 44b works with the nut to achieve a more stable lock.
