[0002] At present, in the construction of substations with voltage levels of 220 kV and above, 1440mm2 steel-core aluminum stranded wire is used the most; the specific gravity of 1440mm2 steel-core aluminum stranded wire is about 5kg / meter, and the corresponding wire clamp is about 10kg / piece, which is very heavy; and because the inner diameter of the wire clamp is the same as the outer diameter of the conductor, after connection, the connection surface fits tightly and without gaps, so the penetration resistance is very large (after actual testing, the average value is about 500N); therefore, the threading process is very intensive.

[0003] At present, the threading process relies on manual threading: two people are required to hold the end of a wire each, and one person holds the wire clamp, and they align and force the wires at the same time. Manual threading is greatly affected by different personnel, duration, skill level, etc. Under the three-person threading method, each set takes an average of about 410 seconds, which is time-consuming (due to the high intensity of the threading process, if two people are used, it will be affected by the strength of the double wires, which is more difficult and time-consuming, so the two-person method is not used in actual work).

[0026] The following is combined with Figure 1-2 The present invention is described in further detail.

[0027] The embodiment of the invention discloses a method for threading a double-conductor wire using a wire clamp of an equipment.

[0028] Reference Figure 1 , Figure 2 , a method for threading a double-conductor device wire clamp, comprising the following steps:

[0029] S1: Install the wire clamp to the wire clamp holding part of the wire clamp fixture 1, install the wire to the wire clamp holding part of the wire fixture 3, and fix the wire clamp and the wire to the corresponding wire clamp fixture 1 and wire fixture 3 through corresponding adjusting members;

[0033] S5: After the wire in the wire holder 3 is connected to the wire clamp of the wire clamp holder 1, the power source 5 stops.

[0034] The wire clamp fixture 1 has a wire clamp holding portion, which is used to fix the wire clamp; the wire fixture 3 has a wire clamping portion, which is used to fix the wire; the power transmission rod 2 is arranged on the wire clamp fixture 1, and the wire fixture 3 is slidably matched and arranged on the power transmission rod 2; the power device includes a power transmission tube 4, which is used to push the wire fixture 3 to move in a direction close to the wire clamp fixture 1, and fix the corresponding wire clamp and wire through the wire fixture 3 and the wire clamp fixture 1, the wire fixture 3 is slidably arranged on the power transmission rod 2, and the power transmission tube 4 pushes the wire fixture 3 to move in a direction close to the wire clamp fixture 1, completes the connection and fixation between the wire and the wire clamp, reduces labor intensity, optimizes the operation process, and achieves efficient threading.

[0035] In this embodiment, the wire clamp holder 1 includes an upper wire clamp fixing plate 9, a lower wire clamp fixing plate 10, an adjusting member 8 and a wire clamp connecting plate. The upper wire clamp fixing plate 9 and the lower wire clamp fixing plate 10 are provided with a wire clamp clamping member 6 for clamping the wire clamp. The upper wire clamp fixing plate 9 and the lower wire clamp fixing plate 10 have a through hole 7 through which the power transmission rod 2 passes. The adjusting member 8 is used to adjust the spacing between the upper wire clamp fixing plate 9 and the lower wire clamp fixing plate 10. The longitudinal section of the upper wire clamp clamping member 6 and the lower wire clamp clamping member 6 is semicircular. The upper wire clamp clamping member 6 and the lower wire clamp clamping member 6 are fitted to form a closed circular wire clamp clamping portion. The upper wire clamp fixing plate 9 and the lower wire clamp fixing plate 10 are slidably matched and arranged on the wire clamp connecting plate. The wire clamp connecting plate has an installation portion for installing the power transmission rod 2, which can enable the power transmission rod 2 to rotate. The wire clamp holder 1 is responsible for fixing the wire clamp so that it does not slide or damage the surface of the wire clamp during threading.

[0036] In this embodiment, the wire holder 3 includes an upper wire fixing plate, a lower wire fixing plate and two adjusting members. The upper wire fixing plate and the lower wire fixing plate are provided with wire clamping members for clamping the wire. The upper wire fixing plate and the lower wire fixing plate have two through holes for the power transmission rod 2 to pass through. The second adjusting member is used to adjust the distance between the upper wire fixing plate and the lower wire fixing plate. The wire holder 3 is responsible for fixing the wire so that it does not slide or damage the wire surface during threading.

[0037] In this embodiment, the wire clamping member includes an upper wire clamping member and a lower wire clamping member, the upper wire clamping member is arranged on the upper fixing plate, and the lower wire clamping member is arranged on the lower fixing plate. The upper wire clamping member and the lower wire clamping member are respectively arranged on the lateral sides of the upper fixing plate and the lower fixing plate. The longitudinal sections of the upper wire clamping member and the lower wire clamping member are semicircular, and the upper wire clamping member and the lower wire clamping member are fitted to form a closed circle to form a wire clamping portion.

[0038] Furthermore, the upper wire clamp and the lower wire clamp as well as the upper wire clamp 6 and the lower wire clamp 6 are implemented in the form of clamps, so that the wire clamp holder 1 and the wire holder 3 can clamp wire clamps and wires of different sizes.

[0039] The adjusting member 1 8 and the adjusting member 2 are bolts, and the wire clamp holder 1 or the wire holder 3 is adjusted by the bolts to clamp the wire clamp or the wire, thereby improving the applicability.

[0040] In this embodiment, the inner wall of the wire clamp 6 and the wire clamp is provided with a protective pad. Specifically, the protective pad is a polyvinyl chloride protective pad, which is firmly adhered and provided on the wire clamp 6 and the wire clamp to prevent the spacer rod from slipping and shifting, and at the same time protect the contact part between the wire and the wire clamp and the wire clamp 6 and the wire clamp to prevent mutual wear, and improve the gripping force of the wire and the wire clamp, and extend the service life. In addition, the protective pad is elastic and can adapt to the outer diameter size of the wire and the wire clamp to ensure their close fit.

[0041] In this embodiment, the power device further includes a power source 5, the power transmission rod 2 is a threaded rod, the power transmission tube 4 is threadedly connected to the threaded rod, and the power source 5 is used to drive the power transmission tube 4 to rotate. Specifically, the power source 5 is an electric wrench, and the rear end of the power transmission tube 4 is provided with a connection portion adapted to the electric wrench, and the electric wrench is clamped with the connection portion.

[0042] In this embodiment, an expansion tube is provided at the front end of the power transmission tube 4. The end face opening of the expansion tube away from the power transmission tube 4 is larger than the diameter of the power transmission tube 4. The expansion tube is coaxially fixed to the power transmission tube 4 and is used to guide the threaded connection between the threaded rod and the power transmission tube 4, which is convenient for docking.

[0043] The power source 5 is an electric wrench, which can provide stable rotational power, and the power transmission rod 2 is a threaded rod, which can form a threaded connection with the power transmission tube 4. The power transmission tube 4 is designed with threads matching the threaded rod, so that when the power transmission tube 4 rotates, the power transmission tube 4 can move along the axial direction of the threaded rod, and the rear end of the power transmission tube 4 is provided with a connection part adapted to the electric wrench, so as to be clamped with the electric wrench, thereby transmitting the rotational power.

[0044] The screw drive has self-locking properties, can ensure the stability and reliability of power transmission, and has high transmission efficiency. In addition, the screw also takes into account the alignment between the wire clamp holder 1 and the wire holder 3 to avoid offset between the two and improve the accuracy of movement.

[0045] When the electric wrench is started, the rotational power is transmitted to the power transmission tube 4 through the connection part. Since the power transmission tube 4 is threadedly connected to the threaded rod, the rotation of the power transmission tube 4 drives itself to move along the axial direction of the threaded rod, thereby pushing the wire holder 3 to move toward the wire clamp holder 1, completing the docking installation between the two.

[0046] According to the present invention, each set of wire clamps takes about one minute to thread and requires one person to do the threading. The threading speed of the wire clamp threading tool for the double-conductor equipment is 10 times faster than that of the manual threading per pair of wire clamps, and two units of labor are saved, thereby achieving the purpose of reducing costs and improving efficiency. The present invention can be widely promoted and applied, and is safe, efficient, and environmentally friendly, thus changing the current traditional manual threading method.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
