Description

Technical Field

[0001] The utility model relates to the field of line fixing structures, in particular to a power transmission and transformation line fixing device. Background Art

[0002] The transmission of electric current often results in losses due to heating of the lines, so during transmission, the voltage is increased through transformers, reducing the current and reducing heat losses. High voltage electricity is highly dangerous, and the target electrical appliances do not require such high voltage, which necessitates the use of transformers to reduce the voltage. Since multiple transformers are required during the transmission of electric current, the transmission of electric current is called transmission and transformation. During the laying of transmission and transformation line wires, fixtures are required to secure the outside of the wires to ensure that the wires occupy the correct position. Transmission and transformation line fixtures are important components in the power system used to support and secure transmission lines, substation equipment, and their ancillary facilities. These fixtures ensure the safe, stable, and efficient operation of power lines.

[0003] For example, the utility model disclosed in the publication number CN211377431U discloses a novel power transmission and transformation line wire fixing device. Through the setting of the fixing mechanism, after the power transmission and transformation line wires are placed, the limit plate can be pressed vertically, and then the threaded sleeve can be rotated to ensure a firm fixation, so that the limit plate and the groove block clamp the power transmission and transformation line wires. The positioning rod can move in the positioning groove to ensure the stability of the structure. The fixing process is relatively simple and easy for users to operate.

[0004] However, each fixing structure of the above-mentioned prior art is realized by a fixing groove provided on the rod, and the distance between each fixing groove cannot be adjusted, which makes it inconvenient for workers to assemble and arrange the wiring when installing the high-altitude memory line at the upper end of the column.

[0039] like Figure 1 and Figure 2 As shown, this embodiment provides a power transmission and transformation line fixing device, including a column 1, the device also includes a hanger 2, an adjustment structure, a hinge 4 and a terminal 7;

[0040] The bracket 2 is fixed on the column 1. The bracket 2 is provided with a mounting groove. The terminal head 7 can be slidably fixed in the mounting groove and is located on the side of the bracket 2 away from the column 1. The sliding direction of the terminal head 7 is perpendicular to the axis direction of the column 1.

The hinge 4 and the adjustment structure are located on the same side of the hanger 2. The hinge 4 is a telescopic structure. The adjustment structure is connected to the terminal 7 through the hinge 4.

[0042] Working Principle: After reaching the top of the tower, a worker opens the adjustment mechanism and adjusts the length of hinge 4 by operating the adjustment mechanism, thereby driving the connection head 7 connected to hinge 4 to slide along the installation slot set on the hanger 2, so that the distance between two adjacent connection heads 7 changes. When the distance between the connection heads 7 meets the requirements, the adjustment mechanism is locked to complete the adjustment of the distance between the connection heads 7.

[0043] By adjusting the spacing between the individual connectors 7 using the adjustment mechanism in conjunction with the hinge 4, the wiring can be installed with the connectors 7 close together. Once installed, the adjustment mechanism can be used to increase the spacing between the individual connectors, ensuring proper operation of subsequent wiring. During installation, the spacing between the connectors 7 and the column is reduced, making wiring more convenient and efficient, and increasing safety during overhead operations. The adjustment mechanism, combined with the hinge 4, allows for simple operation, convenient adjustment, and reliable fixation.

The connector 703 connects the hinge 4, allowing it to interlock with the terminal block 7. The insulator 704 allows for the installation of wires, thereby achieving the desired connection. The handle 503 controls the folding of the hinge 4, thereby operating the device. The rotating groove 502 secures the control rod 500 to the support rod 3, and the stud 504 allows the installation of the fixing rod 6, thereby achieving the desired connection.

[0052] Among them, Figure 3 As shown, the adjustment structure includes a support rod 3, a handle 5 and a fixing rod 6;

[0053] The support rod 3 is fixed to the side of the hanger 2 close to the column 1.

After installation, the distance between the terminal heads 7 can be pulled apart by the handle 5, and then the fixing rod 6 can be installed between the handle 5 and the support rod 3 to fix it.

[0055] Preferred embodiment, as Figure 3 and Figure 4 As shown, the handle 5 includes an L-shaped control rod 500, one end of which is provided with a rotation groove 502, and the control rod 500 can be rotatably fixed on the support rod 3 through the rotation groove 502, and a pulling groove 501 is provided at the bending part of the control rod 500, and the control rod 500 can be rotatably connected to the hinge 4 through the pulling groove 501.

A handle is provided on the outside of the control lever for ease of use, and the lever's adjustment mechanism is quick and easy to operate. A fixed rod locks the position of the control lever, which in turn locks the hinge's connecting rods to ensure structural stability.

[0059] In combination with the above preferred implementation manner, this embodiment also provides a more specific implementation process:

[0060] After the worker climbs to the top of the tower, he removes the fixing rod 6 and then controls the hinge 4 to move in a linkage manner through the handle 5, so that the terminal head 7 can be controlled to move toward the column 1, which makes it convenient for the worker to install the wires on the terminal head 7. After installation, the distance between the terminal heads 7 can be pulled apart by the handle 5, and then the fixing rod 6 can be installed between the handle 5 and the support rod 3 to fix it. The opening of the slide groove 202 and the slot 201 can limit the terminal head 7. After the first connecting rod 400 and the second connecting rod 402 are rotated and connected, the hinge 4 can be folded and retracted, thereby controlling the distance between the terminal heads 7. The hinge 4 can be controlled to fold by the handle 503, thereby achieving the effect of operating the equipment. The control rod 500 can be fixed to the support rod 3 by rotating the groove 502, and the fixing rod 6 can be installed by the stud 504, thereby achieving the effect of fixing.
