[0002] Manual binding is often used on insulators of distribution lines to fix the conductors on the insulators to achieve the purpose of auxiliary fixation. However, the consistency of manual operation is poor and the binding quality is difficult to guarantee. Under natural conditions such as wind and rain, the transmission lines will produce micro-vibrations, which will cause the binding to loosen over time and the fixing effect to deteriorate.
[0003] The existing technology uses a fastening wire clamp to fix the transmission wire to the insulator through the cooperation of structures such as a clamp and a clamping part. However, the operation is relatively cumbersome, which increases the time workers spend working at height and the probability of safety hazards. In addition, the existing fastening wire clamp cannot make adaptive adjustments to the situation where the transmission wire has bends and slopes, and has poor flexibility in use, resulting in unsatisfactory fixing effect.
[0004] Therefore, a fastening clamp for an overhead conductor and an insulator is proposed. Utility Model Content

DETAILED DESCRIPTION
[0029] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. However, the embodiments do not limit the scope of protection of the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on the embodiments are all included in the scope of protection of the present invention.
[0030] Example 1:
[0031] like Figure 1 As shown, a fastening wire clamp for overhead conductors and insulators is disclosed, comprising a pair of clamping rings 1, with through holes formed at the ends of the clamping rings 1, a base plate 3 fixedly mounted on the side of the clamping rings 1 away from each other, a conductor support 2 mounted on the upper surface of the base plate 3, a conductor pressing block 5 fastened to the upper side of the conductor support 2, arcuate grooves 4 for pressing the conductor are formed on the sides of the conductor support 2 and the conductor pressing block 5 close to each other, the aligned arcuate grooves 4 forming a pressing channel, the pressing channel being used to compress and fix the conductor inside; the conductor support 2 and the conductor pressing block 5 can be prefabricated models and then connected and installed with the base plate 3, and can be used for various types of conductors, with a wide clamping range.
[0032] The conductor support 2 and the conductor pressure block 5 are connected and assembled through the connecting component 6, and the two ends of the clamp ring 1 are connected and assembled through the fastening component 7; the split structure is convenient for production. After climbing up, the installer only needs to complete the installation of the fastening clamp and the clamping operation of the conductor through the connecting component 6 and the fastening component 7, thereby reducing the operation time.
[0033] Specifically, the fastening assembly 7 includes a nut 71 and a first fastener 72. Nuts 71 are fixedly installed at both ends of a clamp ring 1, and the first fastener 72 passes through the aligned through holes and is screwed to the nut 71. The connection and installation of a pair of clamp rings 1 can be completed by operating the first fastener 72, which is convenient to operate.
[0034] Specifically, such as Figure 2 As shown, the connecting component 6 includes a second fastener 61 and a screw hole 62. The screw hole 62 is opened on the top of the wire support 2, and the wire pressing block 5 is opened with a through hole. The screw hole 62 and the through hole are symmetrically arranged on both sides of the arc groove 4. The second fastener 61 passes through the through hole and is screwed together with the screw hole 62. The installation of the wire pressing block 5 can be completed by operating the second fastener 61, which is convenient to operate.
[0035] The first fastener 72 and the second fastener 61 are common fastening components such as bolts, jackscrews or quick-press screws, preferably quick-press screws, which can be installed without carrying tools, reducing the operating difficulty of the staff.
[0036] Furthermore, the cross section of the compression channel along the radial direction is elliptical, and the wire with a circular cross section will undergo a slight deformation after compression, which is conducive to compression and fixation.
[0037] The working principle of this embodiment is as follows:
[0038] In this embodiment, the clamp ring 1 and the base plate 3 are fixedly assembled by welding, and the wire support 2 is fixedly assembled on the base plate 3 by welding or rivet anchoring. A plurality of holes for passing rivets are provided on the base plate 3, and the number of rivets of the wire support 2 can be set to adjust the clamping force of the wire.
[0039] Before clamping and fixing the conductor, it can be assembled in the factory or on site without climbing. After climbing, the clamping ring 1 can be quickly clamped and fixed on the insulator through the fastening component 7, and the conductor support 2 and the conductor pressure block 5 can be buckled together through the connecting component 6, so that the conductors on both sides are clamped and fixed through the clamping channel.
[0040] Example 2:
[0041] Another fastening clamp for overhead conductors and insulators is disclosed. The difference from the one in Example 1 lies in the connection method between the clamp ring 1 and the base plate 3. The specific features are as follows.
[0042] The cross-section of the main body of the hoop ring 1 is a circular bent rod. The main body of the hoop ring 1 is provided with a regular polygonal sleeve 8, and the side wall of the regular polygonal sleeve 8 is connected and assembled with the base plate 3; so that the regular polygonal sleeve 8 can move along the main body of the hoop ring 1 and can swing up and down, thereby improving the flexibility of use.
[0043] Connection form of regular polygonal sleeve 8 and base plate 3:
[0044] Form 1, such as Figure 3 As shown, the regular polygonal sleeve 8 and the base plate 3 are fixedly assembled by a connecting rod; the distance between the regular polygonal sleeve 8 and the base plate 3 is fixed, and the structure is more streamlined.
[0045] Form 2, such as Figure 4 As shown, a screw rod 9 is fixedly installed on the side wall of the regular polygonal sleeve 8, and an internal threaded tube 10 is fixedly installed on the lower surface of the base plate 3; through the threaded assembly of the screw rod 9 and the internal threaded tube 10, the distance between the regular polygonal sleeve 8 and the base plate 3 can be adjusted. When other components are installed on the upper part of the insulator, the distance can be adjusted to avoid them, ensuring smooth installation.
[0046] This embodiment describes the working principle using the above-mentioned form 2:
[0047] Before clamping and fixing the conductor, it can be assembled in the factory or on site without climbing. After climbing, the clamp ring 1 is pre-clamped and fixed on the insulator through the fastening component 7, and the internal threaded tube 10 can be rotated by screwing the base plate 3. The distance between the polygonal sleeve 8 and the base plate 3 can be adjusted through the threaded screw 9 to avoid the facilities above the insulator; the conductor support 2 and the conductor pressure block 5 are pre-fastened through the connecting component 6, and the circumferential direction and the up and down swing angle of the base plate 3 are adjusted to adapt to the turning and lifting slope of the conductor, and then the fastening component 7 is locked. At this time, one side of the polygonal sleeve 8 is tightly stuck to the side wall of the vertical pole, thereby fixing the circumferential direction and the swing angle of the base plate 3; then the connecting component 6 is locked, so that the conductors on both sides are clamped through the clamping channel for fixation.
[0048] 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 and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics 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 all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.

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.
