Description

Technical Field

[0001] This utility model relates to the field of power transmission line engineering, specifically to a pole tower steel strand bending device. Background Technology

[0002] Tower guy wires are important structural components used in power engineering to support and stabilize towers. They are mainly used to withstand unbalanced forces on the towers under various working conditions, ensuring the stability and safety of the towers.

[0003] Current methods for constructing guy wires on power poles primarily rely on manual bending of the steel strands before threading them into clamps for secure installation. However, manual bending of the steel strands is extremely laborious and requires a high level of skill and physical strength. The steel strands are prone to not being properly bent and thus cannot be threaded into the clamps, and the quality of the guy wire installation is inconsistent due to the varying skill levels of the workers. When less skilled workers are involved, the steel strands may spring back, posing a safety hazard. This is especially problematic in hot weather, where the physical exertion is significant, making manual bending of the steel strands not only inefficient but also compromises the quality of the work.

[0004] Therefore, in order to solve the above problems, a pole steel strand bending device is needed to solve these problems. Utility Model Content

[0007] Furthermore, the directional wheel assembly includes a positioning shaft installed at the end of the support arm and a directional wheel installed in conjunction with the positioning shaft; the directional wheel is provided with a guide wheel groove in the circumferential direction to cooperate with the bending of the steel strand.

[0008] Furthermore, the bending arm assembly includes a bending arm rotatably mounted on the end of the support arm, a pressure roller disposed on the bending arm, and a pressure handle disposed at the rear end of the bending arm; the pressure roller is used to press the steel strand to bend in conjunction with the directional wheel assembly.

[0009] Furthermore, the front end of the bending arm is rotatably mounted in conjunction with the positioning shaft, and the steel strand is arranged between the directional roller and the pressure roller and bends in conjunction with the rotation of the bending arm.

[0010] Furthermore, the support arm is equipped with positioning guide posts for use with steel strands.

[0011] Furthermore, the support arm is equipped with a locking assembly that works in conjunction with the steel strand positioning rod. The locking assembly consists of two sets of identical structures, which are arranged parallel to each other on the support arm.

[0012] Furthermore, the locking assembly includes a locking block that is installed in conjunction with the support arm and a locking rod that is used in conjunction with the locking block. The locking block has an overall "C" shaped cross-section. The locking block clamps the steel strand and locks it to the support arm through the locking rod.

[0013] Furthermore, the support arm is provided with a flat portion that is positioned and installed in conjunction with the locking block.

As shown in the figure, a steel strand bending device for towers includes a support arm 3, a directional wheel assembly mounted on the support arm 3, and a bending arm assembly used in conjunction with the directional wheel assembly 4. The bending arm assembly is rotatably mounted on the support arm 3 and works in conjunction with the directional wheel assembly 4 to bend the steel strand 1. The steel strand bending device for towers of this technical solution bends the steel strand through the bending arm assembly and the directional wheel assembly. Compared with the traditional method of manually bending steel strands, it not only saves time and effort during the bending process, but also eliminates the risk of springback in the steel strand, thus improving the safety performance during the manufacturing process.

[0021] In this embodiment, the directional wheel assembly 4 includes components mounted on the end of the support arm 3 (i.e., Figure 1 The support arm 3 has a positioning shaft 9 at its lower end and a directional wheel 8 installed in conjunction with the positioning shaft 9. The directional wheel 8 has a guide wheel groove 81 in the circumferential direction to facilitate the bending of the steel strand. The positioning shaft 9 is fixedly installed at the lower end of the support arm 3 for installation in conjunction with the directional wheel 8. The directional wheel 8 is recessed inward in the circumferential direction to form a guide wheel groove 81, which facilitates the bending of the steel strand within the guide wheel groove 81 when the steel strand is bent.

[0022] In this embodiment, the bending arm assembly includes a bending arm 7 rotatably mounted on the end of the support arm 3, a pressure roller 6 disposed on the bending arm 7, and a pressure handle disposed at the rear end of the bending arm 7 (i.e., the end away from the support arm 3). The pressure roller 6 is used to press the steel strand 1 to cooperate with the directional wheel assembly for bending. The bending arm 7 is rotatably mounted in cooperation with the support arm, and the pressure roller 6 is mounted on the bending arm 7 for cooperation. When the bending arm rotates, the pressure roller presses the steel strand into the guide wheel annular groove 81 and rotates synchronously, thereby realizing the bending of the steel strand. The pressure roller 6 is also provided with an annular groove in the circumferential direction to facilitate the positioning and bending of the steel strand 1.

[0023] In this embodiment, the front end of the bending arm 7 is rotatably mounted with the positioning shaft 9. The steel strand 1 is arranged between the directional roller and the pressure roller and is bent in conjunction with the rotation of the bending arm. The bending arm 7 is rotatably mounted with the directional shaft 9, and the steel strand 1 is bent by the pressure handle at the rear end of the bending arm 7 during use.

[0024] In this embodiment, the support arm 3 is provided with positioning guide posts 5 for use with the steel strand. When the steel strand is bent, the positioning guide posts 5 make it easier to position and bend the steel strand, ensuring that the bending meets the usage requirements.

[0025] In this embodiment, the support arm 3 is equipped with a locking assembly 2 that engages with the steel strand positioning rod for locking. The locking assembly 2 consists of two identical sets arranged parallel to each other on the support arm. The identical structure and parallel arrangement of the two sets of locking assemblies facilitate positioning and locking of the steel strand, ensuring that the steel strand does not shift when bent.

[0026] In this embodiment, the locking assembly includes a locking block that is installed in conjunction with the support arm 3 and a locking rod that is used in conjunction with the locking block. The locking block has an overall "C" shaped cross-section. The locking block clamps the steel strand and is locked to the support arm by the locking rod. The locking rod can be installed by bolts and nuts to lock the component. The overall C-shaped cross-section of the locking block facilitates the locking of the steel strand after installation on the support arm. The locking rod is positioned and locked in conjunction with the positioning hole 21 on the locking block to ensure stable and reliable installation when the steel strand is bent.

[0027] In this embodiment, the support arm 3 is provided with a flat portion for positioning and installation in conjunction with the locking block. The flat portion on the support arm 3 facilitates locking and installation with the locking block, ensuring reliable installation.
