Embodiment Construction

[0013] A steel cable connector used for tension stringing of power transmission lines, including a bending-resistant body 1, a cylindrical head screw pin 2 and a sheath 3, the middle of the bending-resistant body is a cylinder, and the two ends are connected to mutually symmetrical spheres, The diameter of the sphere is greater than the diameter of the middle cylinder, the bottom of the opening grooves at both ends of the anti-bending body is arc-shaped and the positions of the two openings are staggered by 90°, the sheath and the anti-bending body are connected together by cylindrical head screws .

[0014] The sphere is symmetrical with the central plane of the opening groove and the plane perpendicular to the central plane and passing through two central points, and the surroundings of the sphere are respectively symmetrical planes.

[0015] The sphere can be replaced by other symmetrical shapes.

Abstract

The invention provides a forked wire cable connector of which the cross section of a connecting point is optimally designed, for tension stringing of a transmission line. The wire cable connector comprises an anti-bending body, a screw pin and a jacket, wherein the middle part of the anti-bending body is a cylinder; the two ends of the anti-bending body are connected with symmetrical spheres; the diameter of each sphere is greater that that of the middle cylinder; open slots at the two ends of the anti-bending body have arc-shaped bottom parts; an angle of 90 degrees is formed between the two open slots; and the jacket is connected with the anti-bending body through the screw pin. The wire cable connector has the advantages of optimally designing the cross section of the connecting point under the condition of limited space, extending the size of a plug mounting slot, enhancing the safety margin of the connector and the wire cable and avoiding the accident that the wire cable jumps over slots or the wire cable is broken when jumping into the second slot when the connector encircles around a winding drum under the rated load.

Description

technical field [0001] The invention belongs to a special machine tool for the connection of tension wire steel ropes for power transmission lines. Background technique [0002] Tension stringing requires hundreds of meters or thousands of meters of steel ropes to be connected into thousands of meters of long ropes, so that the operation of long-distance and high-altitude deployment of wires can be completed through the regulation of the tensioner. [0003] In the 1970s, the tension stringing process began to be implemented in China. With the application of imported tensioning equipment, 8-shaped axial split type and U-shaped anti-bending connectors were introduced from Canada and Italy, and imitated and applied in China. Practice has proved that under normal operating conditions, the breakage of the bending-resistant body connector is often after the connector bypasses the second groove of the tractor drum, and the breakage often occurs on the cross-section of the connectio...
