Description

Technical Field

[0001] This utility model relates to the field of cable accessories and tower structure connection technology, and in particular to a conversion device for connecting cable accessories and tower structures. Background Technology

[0002] In high-voltage transmission lines, after the cable is led out from the substation, it needs to be connected to the overhead line on the tower through the cable terminal head. At this time, a conversion device may be used. One end of the device is connected to the cable terminal head, and the other end is connected to the crossarm or insulator on the tower to realize the transition connection between the cable and the tower, so that the power can be smoothly transmitted from the cable to the overhead line and then to the distance.

[0003] Currently, when connecting cable accessories to tower structures, a dedicated conversion device is typically used in conjunction with a fastening assembly to connect the cable terminal and the tower insulator. This conversion device usually consists of a single conversion cable with lugs at both ends. The lugs and fastening assembly are used to install the cable terminal and the tower insulator. However, the presence of disc-shaped, U-shaped, or rectangular bases at the insulator base makes it inconvenient to connect and adapt the conversion device to the insulator. Therefore, we propose a conversion device for connecting cable accessories to tower structures. Utility Model Content

[0004] The main objective of this invention is to provide a conversion device for connecting cable accessories to a tower structure. An improved matching mechanism is installed at the conversion cable connection point. This matching mechanism has a fixed limiting sleeve A around the conversion cable. The limiting sleeve has round-headed connecting plates, disc plates, and square connecting plates on its horizontal plate, which can be used with three types of tower insulator base plates for installation with screws and nuts. This improves the compatibility of the conversion cable between the cable accessory and the tower structure. Furthermore, the limiting sleeve B has holes in its cylindrical plate, allowing it to be locked to another set of insulators on the tower using bolts and nuts. This ensures that the suspension wire can support the conversion cable after installation, improving the stability of the conversion device and effectively solving the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A conversion device for connecting cable accessories to a tower structure includes a conversion cable and a lug. One end of the conversion cable is fitted with a lug. The device also includes a coupling mechanism comprising a limiting sleeve A, a pressure plate A, a horizontal plate, a circular plate, a round-headed connecting plate, a square connecting plate, a main clamping plate, a secondary clamping plate, a lug sleeve, a suspension cable, a limiting sleeve B, and a pressure plate B.

The disc plate, the round head connecting plate and the square connecting plate are provided with mounting holes. The conversion cable between the wire lug and the sleeve A is provided with a main card seat plate and a secondary card seat plate. A lug sleeve is fixed on one side of the main card seat plate and pressed onto the wire body of one end of the suspension cable. The other end of the suspension cable away from the main card seat plate is pressed onto the wire body of the sleeve B.

[0007] Furthermore, an arc seat plate is provided outside the cylinder of the sleeve A, and the arc seat plate of the sleeve A and the pressure plate A are symmetrically locked outside the conversion cable. The arc seat plate of the sleeve A and the plate surface of the pressure plate A have holes through which bolts and nuts pass to lock them.

[0008] By adopting the above technical solution, after the sleeve A is clamped outside the conversion cable with the arc seat plate, the pressure plate A cooperates with the arc seat plate to clamp outside the conversion cable. Then, bolts are used to pass through the arc seat plate of the sleeve A and the pressure plate A and screw them with nuts, so that the sleeve A can be firmly pressed outside the conversion cable with the arc seat plate and the pressure plate A.

[0009] Furthermore, an arc seat plate is provided outside the cylinder of the sleeve limiting cylinder B, and the arc seat plate of the sleeve limiting cylinder B and the pressure plate B are symmetrically locked outside the lifting line. The arc seat plate of the sleeve limiting cylinder B and the plate surface of the pressure plate B have holes through which bolts and nuts pass to lock them.

[0010] By adopting the above technical solution, after the sleeve limiter B is clamped outside the lifting cable with the arc seat plate, the pressure plate B cooperates with the arc seat plate to clamp outside the lifting cable. Then, bolts are used to pass through the arc seat plate of the sleeve limiter A and the pressure plate A and screw them with nuts, so that the sleeve limiter B can be firmly pressed outside the conversion cable with the arc seat plate and the pressure plate B.

[0011] Furthermore, a short connecting plate is integrally formed between the nose sleeve and the main card seat plate;

[0012] By adopting the above technical solution, the nose sleeve can be connected to the main card seat plate via a short connecting plate.

[0013] Furthermore, a horizontal plate is integrally formed on the outer cylinder plate of the sleeve A, and a round-headed connecting plate is integrally formed on one end of the horizontal plate. A straight plate of a disc plate and a square connecting plate inclined plate are fixed to the outside of the long plate side of the horizontal plate.

[0014] By adopting the above technical solution, after the horizontal plate is fixed at the outer cylinder plate of sleeve A, the round-headed connecting plate, the disc plate and the square connecting plate set at the horizontal plate can be adapted to the installation of three types of iron tower insulator base plates.

[0015] Furthermore, the horizontal plate has symmetrical ribs protruding on both sides, and the ribs of the horizontal plate are trapezoidal ribs.

[0016] By adopting the above technical solution, trapezoidal ribs can be added to the surface of the horizontal plate for reinforcement.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model improves the connection mechanism at the conversion cable used to connect cable accessories and tower structure by setting up a matching mechanism. The matching mechanism has a fixed sleeve A on the outside of the conversion cable. The sleeve has a round head connecting plate, a round plate, and a square connecting plate set at the horizontal plate, which can be matched with three types of tower insulator base plates for installation with screws and nuts, thereby improving the compatibility of the conversion cable between cable accessories and tower structure.

[0019] Furthermore, the sleeve plate of sleeve B has holes that can be locked to another set of insulators on the tower with bolts and nuts, so that the suspension line can support the conversion cable after installation, thus improving the stability of the conversion device.
