[0031] There are two groups of cable body reinforcement components, one group of cable body reinforcement components is welded to the top end of the side of the fixed plate 3, and the other group of cable body reinforcement components is welded to the middle of the fixed plate 3; the cable body 1 passes through the two groups of cable body reinforcement components and is placed in the bending limiter clamping assembly; the cable body reinforcement component includes a cable body fixing mold 11 and a cable body clamping mold 12; the cable body clamping mold 12 is threadedly installed on the cable body fixing mold 11.

[0032] The bend limiter clamping assembly includes a first bend limiter 4, a second bend limiter 5 and a bend limiter clamping die 41; the first bend limiter 4 is placed between the two cable reinforcement assemblies, and the second bend limiter is placed between the anchor cup clamping die 22 and the bend limiter clamping die 41; the bend limiter clamping die 41 is placed below the cable body fixed die 11; the cable body 1 passes through the first bend limiter 4, the bend limiter clamping die 41 and the second bend limiter 5 from top to bottom, and is coaxially aligned with the anchor cup 2.

[0033] A through slot is provided in the bending limiter clamping die 41 for the cable body 1 to pass through; an adjustment sleeve 42 is installed in the through slot; a number of clamping holes are formed on the side walls of the bending limiter clamping die 41 and the side walls of the adjustment sleeve 42; a hole bolt 43 passes through the clamping holes on the bending limiter clamping die 41 and the adjustment sleeve 42 to abut and fix the cable body 1.

[0034] A binding hole is provided on the bolt head of the hole bolt 43; a steel wire is bound in the binding hole to prevent the hole bolt 43 from loosening during casting and vibrating of the cable body 1 and the anchor cup 2.

[0035] The top edge of the second bend limiter 5 does not extend beyond the bottom surface of the hole bolt 43 .

[0036] One side of the bend limiter clamping die 41 and the cable body fixing die 11 are both formed with an assembling fixture, and the bend limiter clamping die 41 and the cable body fixing die 11 are fixedly connected to the second bend limiter 5 and the cable body 1 through the assembling fixture.

[0038] In one embodiment of the present invention, the fixing plate 3 is a fixing channel steel.

[0039] In one embodiment of the present invention, the cable body clamping die 12, the anchor cup clamping die 22 and the adjustment sleeve 42 are all interchangeable die. The die can be interchanged within a certain size range according to the size of the cable body 1, the second bend limiter 5 and the anchor cup 2, so that a set of tooling skeleton can adapt to a variety of cable specifications and can be reused many times, thereby expanding the scope of application of the casting correction tooling, improving the tooling utilization efficiency and reducing the tooling cost.

[0040] In one embodiment of the present invention, the bending limiter clamping die 41 is a structure with an upper circular shape and a lower hexagonal shape, and a clamping hole is provided at the circular structure;

During installation, the upper edge of the second bending limiter 5 does not exceed the dividing point between the circular structure and the hexagonal structure of the bending limiter clamping die. The six holes with hole bolts 43 are used for tying steel wires for fixing to prevent the bolts from loosening during casting and vibration.

[0042] Furthermore, the bending limiter clamping die 41 is positioned with six bolts to adjust the deflection-correcting cable body 1 so that the distance between the six outer side wires of the cable body 1 and the inner wall of the second bending limiter 5 is adjusted to be consistent, ensuring the alignment of the cable body and the anchor to avoid eccentric loading.
