Description

Technical Field

[0001] This utility model relates to power transmission and transformation construction technology, specifically a crimping measuring tool for power transmission and transformation steel-cored aluminum stranded wire. Background Technology

[0002] Crimping technology for steel-cored aluminum stranded wire is widely used in ultra-high voltage power transmission and transformation projects. Crimping tubes (also known as splice tubes) serve a dual function as connectors, providing both mechanical connection and current conduction. If the edge distance dimensions of the crimped tube do not meet design requirements, it can easily cause stress concentration in the conductor, leading to localized overheating when the line is energized. Controlling the crimping length is also crucial. If the crimping area is too short, the tube's grip on the wire will be insufficient; if the crimping is too long, even extending to uncrimped areas, it can cause misalignment, deformation, or even breakage of the steel anchor tube inside the aluminum tube, affecting the crimping quality. Therefore, measurement during the conductor crimping process is an important way to control crimping quality.

[0003] Currently, wire crimping is usually measured using vernier calipers or measuring tapes. Vernier calipers offer high accuracy, but readings require calculation, resulting in low measurement efficiency. Measuring tapes measure the "crimped area" and "non-crimped area," which is cumbersome, inconvenient for high-altitude operations, and poses safety hazards. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a crimping measuring tool for steel-cored aluminum stranded wires used in power transmission and transformation. This tool can quickly measure the distance between opposite edges and the crimping length during wire crimping, offering convenience and speed. The technical solution adopted by this utility model is as follows:

[0005] A crimping measuring tool for steel-cored aluminum stranded wire in power transmission and transformation includes a groove ruler and a length ruler. The groove ruler includes a base plate, and the edge of the base plate is provided with a plurality of aluminum mold grooves and / or steel mold grooves for detecting the edge distance of the crimped wire. The length ruler is provided with a "non-crimping area" and a "crimping area" for detecting the crimping length. The "crimping area" is located on both sides of the "non-crimping area".

[0006] The aforementioned crimping measuring tool for steel-cored aluminum stranded wires for power transmission and transformation has a base plate that is a circular steel plate with two aluminum mold slots of different specifications and two steel mold slots of different specifications.

[0007] The beneficial effects of this utility model are as follows: the base plate can quickly detect the edge distance of the crimping pipe for both steel core and aluminum strands, and the length ruler can quickly detect the crimping length, which greatly improves the crimping measurement efficiency, is easy to carry, and ensures the safety of high-altitude operations.

[0011] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings.

[0012] The following embodiments are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical terms used have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. It should be noted that the terminology used is for the purpose of describing particular embodiments only and is not intended to be limiting according to this application.

[0013] This embodiment discloses a crimping measuring tool for steel-cored aluminum stranded wire in power transmission and transformation, comprising a base plate 1 and a length ruler 2. The base plate 1 has several aluminum mold slots 11 and / or steel mold slots 12 along its edge for detecting the edge distance of the crimping tube. The length ruler 2 has a "non-crimping zone" and a "crimping zone" for detecting the crimping length, with the "crimping zone" located on both sides of the "non-crimping zone". The length ruler 2 is configured with specific dimensions for the "non-crimping zone" and the "crimping zone" according to the specifications or manufacturer's technical parameters for different models of crimping tubes.

[0014] The aforementioned crimping measuring tool for steel-cored aluminum stranded wires for power transmission and transformation has a base plate 1 that is a circular steel plate with two aluminum mold slots 11 and two steel mold slots 12 of different specifications to increase versatility.

[0015] The process of using this measuring tool is as follows: Select the appropriate crimping tube model according to the specifications of the steel-cored aluminum stranded wire, thereby determining the dimensions of the aluminum mold slot 11 and the steel mold slot 12, as well as the standard lengths of the "uncrimped area" and the "crimped area"; Use the corresponding slot to check the edge distance of the crimping tube. If the slot cannot be inserted into the crimping tube, the crimping is unqualified and needs to be carefully crimped again until the slot can be inserted into the crimping tube, then the test result is qualified; Align the end of the length ruler 2 with the end of the crimping tube (or tension clamp), making it parallel to the crimping tube, and judge the result by comparing the crimping lengths corresponding to the "uncrimped area" and the "crimped area".

[0016] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various changes or improvements without departing from the principles of this application, and these changes or improvements should also be considered within the scope of protection of this application.
