Description

Straightening device for ACSR

technical field

The utility model relates to a straightening device, in particular to a straightening device for steel-cored aluminum stranded wires.

Background technique

Steel-cored aluminum stranded wire is a reinforced wire with single or multi-layer aluminum strands twisted outside the galvanized steel core wire. Mainly used in electric power and transmission line industry. It has a steel "core" inside, and aluminum wires are twisted around the steel core on the outside; the steel core mainly plays the role of increasing strength, and the aluminum stranded wire mainly plays the role of transmitting electric energy; The outermost layer is coated with a layer of zinc to avoid oxidation of the inner core wire.

In the actual production of ACSR, sometimes it is necessary to detect the quality of the surface galvanized layer, so as to judge the specific composition and related technical data of the ACSR. The detection process generally dissolves the galvanized layer on the surface of the steel-cored aluminum stranded wire through the solution, and calculates the thickness and quality of the galvanized layer by calculating the quality difference before and after the dissolution. Specifically, the steel-cored aluminum stranded wire is wound into a Tubular, can be placed into a cylindrical beaker for dissolution. However, after the inspection is completed, the shape of the tubular ACSR should be restored. In the existing technology, the restoration process is mostly that the workers manually straighten the wires with their hands. This process is time-consuming and laborious, and the workers vulnerable.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

Embodiment 1: A straightening device for steel-cored aluminum stranded wire, referring to Fig. 1 to Fig. 3, it is provided to include a fixing device 2 using a forward and reverse motor as a power source, a frame 3 where the fixing device 2 is located, and a machine The clamping device 4 installed at the other end of the frame 3 is provided with a fixed end for fixing the aluminum stranded wire on the fixing device 2 and the clamping device 4 . Between the clamping device 4 and the frame, it is a sliding fit.

The clamping device 4 can clamp the straightened aluminum-steel conductor.

A dynamometer is installed on the clamping device 4 to detect the tension of the wire rod in time to prevent the wire rod from being broken due to excessive pulling force.

The clamping device 4 is a half-round head plate with a through hole, and the half-round head plate is divided into two detachable parts along the chord of the through hole, as shown in FIG. 4 . When the work is finished, the clamping device is disassembled, and the straightened ACSR can be taken out.

In this embodiment, a guide device is also provided between the fixing device 2 and the clamping device 4, and the guide device is a guide plate with a through hole, and the guide plate forms a support for the displacement channel of the steel-cored aluminum strand. Corresponds to the wire diameter of the steel-reinforced aluminum stranded wire. It plays a guiding role in the straightening process of the steel-reinforced aluminum strand.

The guide plate is not shown in the accompanying drawings. In actual use, it can be a guide plate installed on a frame with an aluminum-steel wire track, or a support forming a steel-cored aluminum-stranded wire travel channel.

During the working process, the motor rotates forward and reversely to drive the bent aluminum stranded wire to rotate. During the rotation, the clamping device 4 clamps the other end and pulls it outward with a constant tension. The helix is of the opposite direction. In the end, a linear steel-reinforced aluminum strand is formed.

Embodiment 2: The principle of this embodiment is the same as that of Embodiment 1, except that the clamping device includes two clamping blocks, an upper and a lower one, and a set screw 41 is installed between the two clamping blocks. After the set screw 41 is clamped, the aluminum stranded wire is fixed. When it needs to be disassembled, loosen the set screw 41 accordingly.
