Abstract
Description
Technical Field
[0001] This utility model relates to an insulator conductor fixing device, and more particularly to an adjustable insulator conductor fixing device. Background Technology
[0002] Porcelain insulators are widely used for insulation and mechanical fixing of overhead high and low voltage power distribution lines.
[0003] Currently, in my country's power system, the common method for securing overhead power line conductors to porcelain insulators is by manual binding using BV insulated wire or aluminum wire. The porcelain insulator has grooves on top for the conductors to be inserted, and the binding wire secures the conductor within these grooves. This manual binding method is inconvenient and inefficient. Furthermore, the binding wire itself has low mechanical strength, leading to wire breakage over time, conductor detachment, and even conductor wear and breakage.
[0004] Currently, insulator conductor fixing devices are also used to fix the conductors of overhead power distribution lines, but existing insulator conductor fixing devices can only be used with one type of insulator and a small range of conductor diameters, resulting in poor versatility. Summary of the Invention
[0005] To address the aforementioned shortcomings, this utility model provides an adjustable insulator conductor fixing device that can fix conductors of various diameters onto insulators of various neck sizes, preventing the cable from detaching from the insulator.
[0006] To achieve the above objectives, this utility model employs an adjustable insulator conductor fixing device, comprising a clamping block and a pressure cap. Both the clamping block and the pressure cap adopt a structure with embedded high-strength alloy metal inserts and an outer coating of engineering plastic. Bolts are provided on the clamping block, and the pressure cap is connected to the upper part of the clamping block by bolts. The clamping block includes a left clamping block and a right clamping block. One end of the left clamping block and the right clamping block are hinged together by bolts. The other end of the left clamping block forms a hinged opening. A hinged pin is provided at the lower part of the hinged opening, and a hinged bolt is provided inside the hinged opening. The hinged bolt is riveted to the left clamping block by the hinged pin and can rotate flexibly by the hinged pin. The other end of the right clamping block forms multiple adjustment openings adapted to the hinged opening. The adjustment openings are located above the hinged opening. When the hinged bolt swings upward, it can be locked in the adjustment opening to fix the right clamping block.
[0007] The beneficial effects of this utility model are that it uses left and right clamping blocks to clamp the neck of the insulator. By setting multiple adjustment openings and adjusting the clamping size through the hinge bolt on the left clamping block, it can be installed and used on insulators with different necks, which is very versatile. The space for clamping the neck of the insulator formed by the left and right clamping blocks is adjusted by using hinge bolts to engage with multiple adjustment openings, which is efficient and provides a stable and reliable clamping effect. The left and right clamping blocks and the pressure cover adopt a structure with embedded high-strength alloy metal inserts and an outer coating of engineering plastic. The embedded metal inserts have high strength and good clamping force, which ensures that the conductor is fixed in the insulator groove. The outer coating of engineering plastic ensures that the conductor and insulator are not damaged. The overall fully insulated installation improves the insulation safety performance of the line.
[0008] Specifically, a pad is provided inside the pressure cap. The lower end of the pad forms a small arc-shaped wire pressing groove, and the upper end of the pad forms a positioning rod. The pressure cap has a pad mounting hole, and the pad is positioned and connected to the pressure cap by passing the positioning rod through the pad mounting hole. The pad inside the pressure cap secures the wire and can be used for wires with diameters of 50–150 mm. 2 The wires are securely and reliably fixed.
[0009] Specifically, a large arc-shaped wire-pressing groove is formed in the lower center of the pressure cap. This large wire-pressing groove, directly located below the pressure cap, secures the wire and can accommodate wire diameters of 150–300 mm. 2 The wires are securely and reliably fixed.
[0010] The above technical solution enables this utility model to achieve a resolution of 50-300mm. 2 Universal wiring installation.
[0011] Specifically, the two ends of the gland form fixing holes for bolts and hinge bolts to pass through, and torque nuts are provided above the fixing holes. Two torque nuts are connected to the bolts and hinge bolts respectively, and the torque nuts are covered with insulating covers.
[0012] Specifically, the insulating cover adopts a split structure, with two insulating covers respectively covering two torque nuts. The outer side of the insulating cover forms an elastic fastener, and the two ends of the pressure cover form a buckle. The insulating cover is fixed to the pressure cover by the cooperation of the elastic fastener and the buckle.
[0013] Specifically, the insulating cover adopts an integral structure, with two insulating covers connected as a whole by a cover plate. The cover plate covers the pressure cover, and the cover plate extends downward around its perimeter to form cover plate buckles. Corresponding to the cover plate buckles, the pressure cover forms a snap-fit platform. The cover plate is fixed to the pressure cover by the cooperation between the cover plate buckles and the snap-fit platform.
[0014] The aforementioned technical solution has a cover equipped with a device for installing and fixing both split-type and integral-type insulating covers. It can be configured with either a split-type or integral-type insulating cover according to project needs, making it more convenient.
[0015] Specifically, the fixing hole at one end of the pressure cap through which the hinge bolt passes has a strip-shaped opening to one side. This easy-to-open strip-shaped opening on one side of the pressure cap allows for installation without fully tightening the torque nut, ensuring that the bolt and nut remain in place, thus facilitating work at heights.
[0016] Specifically, there are two pads, and there are also two pad mounting holes on the cover. The two pads are arranged in a front-to-back pattern under the cover.
[0017] Specifically, the right clamping block has three adjustment openings, which are arranged sequentially on the right clamping block. Attached Figure Description

[0021] Figure 4 This is an exploded view of a specific embodiment 2 of this utility model. Detailed Implementation
[0022] like Figure 1 , Figure 2 As shown, a specific embodiment 1 of this utility model is an adjustable insulator conductor fixing device, including a clamping block and a pressure cap 3. Both the clamping block and the pressure cap 3 adopt a structure with embedded high-strength alloy metal inserts and an outer coating of engineering plastic. The clamping block includes a left clamping block 1 and a right clamping block 2. One end of the left clamping block 1 and the right clamping block 2 are hinged together by bolts 4, which extend upwards. The pressure cap 3 is connected above the clamping block by bolts 4. The other end of the left clamping block 1 forms a hinge opening 11. A hinge pin 12 is provided at the lower part of the hinge opening 11. A hinge bolt 5 is provided inside the joint opening 11. The hinge bolt 5 is riveted to the left clamping block 1 through the hinge pin 12 and can rotate flexibly through the hinge pin 12. The other end of the right clamping block 2 forms three adjustment openings 21 that are adapted to the hinge opening 11. The three adjustment openings 21 are arranged in sequence on the right clamping block 2. The adjustment openings 21 are located above the hinge opening 11. When the hinge bolt 5 swings upward, it can be locked in the adjustment opening 21 to fix the right clamping block 2, so that the left clamping block 1 and the right clamping block 2 are clamped on the neck 91 of the insulator 9.
[0023] The pressure cap 3 has two pads 6, one at the front and one at the back. The lower end of the pad 6 forms a small arc-shaped wire groove 61, and the upper end of the pad 6 forms a positioning rod 62. The pressure cap 3 has pad mounting holes 31. The pad 6 is positioned and connected to the pressure cap 3 by passing through the pad mounting holes 31 through the positioning rod 62. The wire 8 passes through the small wire groove 61 below the pad 6. The pad 6 can accommodate wires with a diameter of 50-150mm. 2 The wire 8 is securely and reliably fixed. A large arc-shaped wire groove 36 is formed in the lower center of the pressure cap 3. This is suitable for wires with diameters of 150–300 mm. 2 When fixing the wires, the pad 6 can be removed, and the large wire-fixing groove under the pressure cap can be used directly to fix the wires. By flexibly using the pressure cap 3 and the pad 6, it is possible to fix the wires from 50 to 300 mm. 2 Universal wiring installation.
[0024] The pressure cap 3 has fixing holes 32 at both ends for bolts 4 and hinge bolts 5 to pass through. Torque nuts 33 are positioned above the fixing holes 32, and the two torque nuts 33 are connected to the bolts 4 and hinge bolts 5 respectively. An insulating cover 7 is fitted over the torque nuts 33. A strip-shaped opening 37 is provided on one side of the fixing hole 32 for the hinge bolts 5 to pass through. The strip-shaped opening 37 allows the torque nuts 33 to be installed without being fully unscrewed, ensuring that the bolts and nuts remain in place, facilitating high-altitude operations. In this embodiment, the insulating cover 7 has a split structure, with two insulating covers 7 respectively covering the two torque nuts 33. Elastic fasteners 71 are formed on the outer side of the insulating covers 7, and buckles 34 are formed at both ends of the pressure cap 3. The insulating covers 7 are fixed to the pressure cap 3 by the cooperation of the elastic fasteners 71 and the buckles 34.
[0025] like Figure 3 , Figure 4 The specific embodiment 2 of this utility model shown is also an adjustable insulator wire fixing device. The insulating cover 7 of this embodiment adopts an integral structure. The two insulating covers 7 are connected into a whole by a cover plate 72. The cover plate 72 covers the pressure cover 3. The cover plate 72 extends downward around its perimeter to form a cover plate buckle 73. The pressure cover 3 forms a snap-fit platform 35 corresponding to the cover plate buckle 73. The cover plate 72 is fixed on the pressure cover 3 by the cooperation of the cover plate buckle 73 and the snap-fit platform 35.
[0026] In a specific embodiment of this utility model, the pressure cover may also be provided with a buckle 34 for fixing a split insulating cover and a snap-fit platform 35 for fixing an integral insulating cover. The insulating cover can be configured with a split structure or an integral structure according to the engineering needs, which is more convenient.
