Description

Technical Field

[0001] The invention relates to a transmission line construction machine and construction technology, and in particular to a wire clamp for a carbon fiber conductor. Background Art

[0002] With the rapid development of ultra-high voltage construction and new materials, carbon fiber composite core conductors have been widely used due to their advantages such as high tensile strength, low sag, corrosion resistance, light weight and strong conductivity. However, carbon fiber conductors have poor bending resistance. During the process of lifting the conductors after crimping during tension line construction, the conductors at both ends of the wire clamp may bend at a large angle, which may cause the carbon fiber core rod to bend or even break the conductor. This poses a great safety hazard to the line construction of carbon fiber composite core conductors.

[0003] The large-scale application of carbon fiber composite core conductors places higher demands on stringing construction technology, especially in the intermediate tension field. After the conductors are deployed at both ends, they must be crimped together before being hoisted. Due to the poor bending resistance of carbon fiber composite core conductors, using conventional wire clamps to hoist the conductors can easily cause significant bending, which can damage the carbon fiber core rods and even cause the conductor to break.

[0104] Specifically,

[0105] like Figures 1 to 5 As shown, the wire anti-bending wire clamp 12 provided by the present invention is mainly composed of an upper snake section 1-1, a lower snake section 1-2, an upper connector 2-4, a lower connector 2-5, an upper pressure plate 3-4, a lower pressure plate 3-5, a fixing member 4 and a fastener 5. The fixing member 4 can be a main connecting rod, and the fastener 5 can be a stud for connecting and fastening, and the stud is a double-threaded stud. Each part of the wire clamp 12 is interchangeable and reusable, reducing construction costs.

[0106] The curvature of the snake segment ranges from 20 to 50d, where d is the conductor diameter. The number of snake segments is generally 3 to 5, and the angle of each segment ranges from 3 to 10°. This design disperses the large bending angles of the conductor and prevents damage to the conductor due to excessive bending.

[0107] The second wire through holes 3-3 of the upper pressing plate 3-4 and the lower pressing plate 3-5 have the same diameter as the wire 6, but the centers of the second wire through holes 3-3 of the multiple pressing plates are staggered up and down, which can ensure that the wires are clamped; and the centers of the first wire through holes 2-3 of the multiple connectors coincide, which can ensure that the connectors 2 are tightly connected and the snake section 1 is smoothly installed and used;

[0108] The main connecting rod 4 and the double-headed stud 5 tightly connect the 5 pressure plates and 2 connectors in series. The 5 middle pressure plates compress the wire 6 through the bolt 7 to lock the wire 6 and play the role of clamping the wire. The connectors 2 at both ends are respectively connected to the 3 snake nodes 1. The function of the snake node 1 is to disperse the large bending angles of the wire 6 to prevent the wire 6 from being damaged due to excessive bending. When installing the wire clamp, first connect the lower connector 2-5 and the lower pressure plate 3-5 tightly and rigidly in series through the fastener 5 and the fixing part 4, put the carbon fiber wire 6 into the first wire through-hole 2-3 of the lower connector 2-5 and the second wire through-hole 3-3 of the lower pressure plate 3-5, and then connect the upper connector 2-4 with the lower connector 2 -5 and the upper pressure plate 3-4 are movably connected to the lower pressure plate 3-5 through the same fastener 4. Then, the upper snake section 1-1 and the lower snake section 1-2 are wrapped around the wire 6. The snake section 1 is flexibly connected at both ends and flexibly connected to the connector 2. The upper snake section 1-1 and the lower snake section 1-2 are fastened by radial bolts 7. The upper connector 2-4 and the lower connector 2-5 are then fastened together by bolts 7, and the upper pressure plate 3-4 and the lower pressure plate 3-5 are finally fastened together. This completes the installation process. When the wire clamp is to be disassembled, the bolts 7 are first unscrewed, and then the upper snake section 1-1, the upper connector 2-4, and the upper pressure plate 3-4 are opened; at this point, the carbon fiber wire 6 can be removed.

[0109] like Figures 6 and 7 As shown, the large-scale application of carbon fiber composite core conductor 6 puts forward higher requirements for its line construction technology, especially in the intermediate tension field. After the conductors at both ends are deployed, it is necessary to crimp the two ends of the conductor and then perform the lifting operation. The conductor 6 passes through the wire clamp and moves upward through the pulley 9. The main connecting rod on the wire clamp is connected to the wire loosener 8. Due to the poor bending resistance of carbon fiber composite core conductor, it is easy to cause the conductor to be greatly bent when using a conventional wire clamp to lift the conductor, thereby damaging the carbon fiber core rod and even breaking the conductor. The wire clamp provided by the present invention solves this problem, thereby improving the efficiency and safety of the conductor lifting.

[0110] The above are merely embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the scope of the claims of the present invention to be approved.
