[0030] In the following, one steel wire joint crimping positioning scheme of the AS method suspension bridge main cable construction of the present application will be introduced and described in detail through several specific embodiments.

[0031] Embodiment 1

[0032] Please refer to Figure 1 which shows the overall structure schematic view of one embodiment of the steel wire joint crimping positioning device of the present application. The steel wire joint crimping positioning device has an included angle between the first positioning plane and the second positioning plane. The clamping device includes the first clamping part 1 and the second clamping part 2. The first clamping part 1 is provided with the first clamping groove, and the second clamping part 2 is provided with the second clamping groove. When the first clamping part 1 and the second clamping part 2 are clamped and connected, the first clamping groove and the second clamping groove form the accommodating hole 5 for clamping the steel wire. The clamping device is connected to the positioning structure, and the accommodating hole 5 is fixed relative to the first positioning plane and the second positioning plane.

[0033] In the above embodiment, when the steel wire joint crimping positioning device of the present application is used, the steel wire is clamped by the clamping device, and then the first positioning plane of the positioning structure is arranged in close contact with a platform horizontal surface. The platform has a horizontal surface for cooperating with the first plane or the second plane. Then the steel wire joint crimping device is used to perform the first crimping on the two steel wires to be crimped.

[0034] After the first crimping is completed, the positioning structure is adjusted to be arranged in close contact with the platform horizontal surface by the second positioning plane. Since the first positioning plane and the second positioning plane have an included angle, the steel wire also rotates with the displacement of the positioning structure. For example, when the length direction of the accommodating hole 5 is parallel to the first positioning plane or the second positioning plane, and the first positioning plane and the second positioning plane are perpendicular, the steel wire rotates 90 degrees under the driving of the positioning structure during the process of arranging the positioning structure from the first positioning plane and the platform horizontal surface in close contact to the positioning structure and the second positioning plane in close contact.

[0035] ​For example, the positioning structure is a columnar body with at least three faces. The steel wire is fixed relative to the columnar body by the clamping device, and the length direction of the steel wire is parallel to the axial direction of the columnar body. In construction, one face of the columnar body is arranged in abutment with the horizontal surface of the platform. Then the two sections of the steel wire to be crimped are crimped, and then the columnar body is rotated so that another face of the columnar body is arranged in abutment with the horizontal surface of the platform. If the columnar body is a cube, the columnar body is rotated by 90 degrees, and the rotation angle of the steel wire is also 90 degrees. For example, the positioning structure is a hexagonal column with six faces. The columnar body is rotated by 60 degrees, and the rotation angle of the steel wire is also 60 degrees.

[0036] In summary, the steel wire is clamped by the accommodation hole, and the angle at which the steel wire needs to be rotated is quickly determined by the first plane and the second plane on the first positioning block. When the steel wire is rotated, the rotation angle of the steel wire is intuitively displayed to the construction personnel by the parallelism display rod. Finally, the construction personnel can conveniently determine whether the rotation angle of the steel wire meets the requirements.

[0037] Embodiment 2

[0038] Further, please refer to Figure 1 , Figure 2 and Figure 3 Another embodiment of the steel wire joint crimping and positioning device provided by the application is that the cross section of the accommodation hole 5 is oval.

[0039] In the above embodiment, the steel wire needs to be clamped by the first clamping groove and the second clamping groove. Therefore, the first clamping groove and the second clamping groove are both semicircular grooves, and the first clamping groove and the second clamping groove form an accommodation hole 5 with an oval cross section.

[0040] Embodiment 3

[0041] Further, please refer to Figures 4-7 Another embodiment of the steel wire joint crimping and positioning device provided by the application is that the clamping device further comprises a first rod body 3 with a semicircular cross section, a second rod body 4 with a semicircular cross section, and a nut 6. The first rod body 3 is fixedly connected with the first clamping part 1, and the second rod body 4 is fixedly connected with the second clamping part 2.

[0042] The outer surface of the first rod body 3 has a first thread, and the outer surface of the second rod body 4 has a second thread. When the first rod body 3 and the second rod body 4 are matched, the third thread formed by the first thread and the second thread can engage with the nut 6, and the first clamping part 1 and the second clamping part 2 are clamped and connected.

[0043] In the above embodiment, the clamping device is composed of the first clamping part 1, the second clamping part 2, the first rod body 3, the second rod body 4, and the nut 6. For example, Figure 6 and Figure 7As shown, the first rod body 3 and the first clamping part 1 are fixed, and the second rod body 4 and the second clamping part 2 are fixed. When the first rod body 3 and the second rod body 4 are attached, the first thread and the second thread can form a third thread, and the third thread can engage with the nut 6. When the nut 6 is screwed onto the first rod body 3 and the second rod body 4, the nut 6 will fix the first rod body 3 and the second rod body 4.

[0044] In use, as shown in Figure 6 and Figure 7 , the steel wire is placed into the first clamping groove on the first clamping part 1, and then the second clamping groove of the second clamping part 2 is aligned with the first clamping groove. The steel wire is placed in the first clamping groove and the second clamping groove. Then the nut 6 is screwed onto the first rod body 3 and the second rod body 4, and after the nut is screwed in, the steel wire is clamped. If the diameter of the steel wire is longer than the diameter of the accommodating hole 5, due to the triangular force, the deeper the nut 6 is screwed in, the tighter the first clamping part 1 and the second clamping part 2 clamp the steel wire. In this embodiment, the shape formed by the first rod body 3 and the first clamping part 1 is similar to half of a bolt, and the shape formed by the second rod body 4 and the second clamping part 2 is similar to the other half of the bolt, as shown in Figure 6 and Figure 7 . The first clamping part 1, the second clamping part 2, the first rod body 3 and the second rod body 4 form a complete bolt structure. When the nut 6 cooperates with the bolt structure, the first positioning plane is located at the top surface of the bolt structure, and the second positioning plane is a surface of the nut 6. When the bolt structure is stood up, the first positioning plane and the horizontal plane of the platform are attached, and when the bolt structure is laid on one side, the second positioning plane on the nut 6 is attached to the horizontal plane. The design is simple in structure and convenient to use.
