Embodiment 1

[0025] Embodiment one, such as Figure 1-5 As shown, according to the embodiment of the present invention, a double-ear wedge-shaped clamp for die-forging load-bearing cables includes a double-ear wedge-shaped clamp 1, and two double-ear wedge-shaped clamps 1 are arranged symmetrically. The sides of the clamp 1 in the circumferential direction are clamped and provided with elastic connectors 25, and a wedge cavity 2 is provided in the double-ear wedge-shaped wire clamp 1, and a wedge block 3 is provided in the wedge cavity 2. The double-ear wedge-shaped The top and the bottom of the clamp 1 are provided with two threaded holes 4, the threaded holes 4 are provided with bolts 10, the bolts 10 are provided with nuts 11, the bolts 10 and the nuts 11 connect the two The double-eared wedge-shaped wire clamp 1 and the elastic connector 25 in the middle are fixed together. One side of the double-eared wedge-shaped wire clamp 1 is provided with a connecting ear 5, and the middle part o...

Embodiment 2

[0026] Embodiment 2, the connecting ears 5 on the two double-eared wedge-shaped clamps 1 form double ears, and the connecting ears 5 and the double-eared wedge-shaped clamp 1 are integrally structured. It is not difficult to see from the above design that the design of the ears is relatively conventional, so no detailed description will be given.

Embodiment 3

[0027] Embodiment 3, the elastic connecting piece 25 is made of elastic metal material, the elastic connecting piece 25 is matched with the side of the double ear wedge clamp 1, the first chute 8 is connected with the second chute The specification of 13 is identical, and the specification of described draw-in slot one 9 is identical with described draw-in slot two 14. It is not difficult to see from the above design that the design of the elastic connector is relatively conventional, so no detailed description will be given.

Abstract

The invention discloses a double-ear wedge-shaped wire clamp for die-forging load-bearing cables, which comprises a double-ear wedge-shaped wire clamp. Elastic connectors are provided for edge clamping, a wedge cavity is provided in the double-ear wedge-shaped clamp, wedges are provided in the wedge cavity, and two threaded holes are provided on the top and bottom of the double-ear wedge-shaped clamp , the threaded hole is provided with a bolt, and the bolt is provided with a nut, and the bolt and the nut fix the two double-ear wedge-shaped clamps and the elastic connector in the middle together, the One side of the double-ear wedge-shaped clamp is provided with connecting ears. Beneficial effects: the double-ear wedge-shaped clamp is made of forging, there is no corresponding defect in casting molding, no flaw detection is required, and the production efficiency of forging is high, which reduces the manufacturing cost, eliminates the hidden safety hazard caused by casting defects, and improves the quality of the catenary. Manufacturability of safe operation.

Description

technical field [0001] The invention relates to the technical field of double-ear wedge-shaped wire clamps, in particular to a double-ear wedge-shaped wire clamp for die-forged load-bearing cables. Background technique [0002] The double-ear wedge-shaped wire clamp is a thread clamping part for the catenary cable, contact wire, and guy wire at the terminal connection and anchor connection of the electrified railway. Such as figure 1 shown. The reliability of its connection and anchorage directly affects the safe operation of the catenary. Among them: 1 is the clue, 3 is the body of the double-ear wedge-shaped clamp, 2 is the wedge, and 6 is the connection hole, which is an integral casting structure, such as figure 1 shown. Since the cast steel casting process cannot completely guarantee that the castings are free from defects such as pores, cracks, and inclusions, and requires piece-by-piece radiographic flaw detection, the qualified rate of castings is only 65%. Make...
