Description

Technical Field

[0001] The present invention relates to the technical field of wire equipment, in particular to a wire clamp and a use method thereof. Background Art

[0002] Due to different working conditions, the wire grippers hold different types and specifications of wires, and are divided into: aluminum alloy wire grippers, insulated wire grippers, steel stranded wire grippers (applicable to steel stranded wires), ground wire grippers, single-pole grippers, double-pole grippers, frog-type grippers, and anti-twist wire rope grippers. They are suitable for adjusting sag and tightening wires in overhead power lines.

[0003] With the rapid development of electrification equipment, the length and diameter of line installations have increased significantly. In order to firmly clamp the wires, the size and specifications of the wire clamps have become larger to increase the clamping force of the wires. However, as the diameter of the wires continues to increase, the size and weight of the wire clamps have increased exponentially. The main reason is that the existing wire clamps mostly use eccentric clamping. In order to ensure the clamping force, the volume of the actuator needs to be increased, which results in a huge volume and weight of the wire clamps, which not only increases the difficulty of installation, but also poses serious safety hazards in windy, rainy and snowy weather.

[0052] Compared with the prior art aluminum alloy wire clamps, insulated wire clamps, steel strand clamps (applicable to steel strands), ground wire clamps, single-pole clamps, double-pole clamps, frog-type clamps and anti-twist wire rope clamps, the greatest advantages of embodiments 1, 2 and 3 are that the wire shaft diameter and material are widely applicable, such as Figure 4 , 6 As shown in FIGS. 7 and 8, the outer wire clamping cylinder 1 and the inner wire clamping cylinder 2 are in a cone barrel shape, and the outer wire clamping cylinder 1 and the inner wire clamping cylinder 2 fit each other in a taper and are self-locking, so that they can be applied to wire clamping operations with different diameters. Figure 7 As shown, the application range can be further broadened by adjusting the thickness of the inner tube 2. The wire clamp avoids the drawback of the existing equipment that needs to adjust different models and volumes according to the tension of the wire, and greatly reduces the size of the wire clamp. Figure 1 and 10 As shown in the figure, due to the use of the outer and inner tubes of the clamping wire set and the taper self-locking connection, the material strength requirements of the outer and inner tubes of the clamping wire are reduced, and ordinary steel, aluminum, and alloys can be used. Figure 2 As shown, when the wire clamp is self-locking at the taper, the outer clamping tube 1 and the inner clamping tube 2 move along the axial direction of the wire, and the taper self-locking movement direction is consistent with the wire stretching direction, which greatly reduces the radial size. The overall structure is compact and light, and is particularly suitable for use in low-temperature snowy environments. Not only is the wire clamp not easy to accumulate snow, but the overall compact volume of the wire clamp and the cone barrel shape also make it easy to clean the snow.
