Technical Field

[0001] The invention relates to the field of high-voltage electrical switch assembly, and in particular to a conductive assembly pressing device for an isolating switch. Background Art

[0002] Before the improvement, the disconnector's conductive assembly was manually pressed down. After securing the base of the conductive tube, multiple people worked together to apply tension or pressure to the tube, causing it to rotate and press downward. During the downward pressure process, the tube maintained a rebound force, and manual force was continuously applied until the tube was secure.

[0003] Its disadvantages are: it requires the collaboration of multiple people, is time-consuming and labor-intensive; and the rebound force when human power is used poses a greater safety risk to people. Summary of the Invention

DETAILED DESCRIPTION

[0020] As shown in the figure, the present invention is a conductive assembly downward pressure device for disconnecting switches. It consists of an electric wire winch, a mechanical arm, and a supporting steel frame, all mounted on a fixed base (not labeled in the figure). The mechanical arm is positioned in the center, with supporting steel frames 3 mounted on either side of the mechanical arm 2, each with a pulley 13 at the top. An electric wire winch 1 is mounted below and behind the mechanical arm, equipped with a wire rope 12. The electric wire winch is axially divided into sections A and B along the winding direction. Sections A and B have equal diameters, and the wire ropes are wound in opposite directions. One end of the wire rope is wound around section A, passed around a pulley at the top of one supporting steel frame, and connected to a rope clip on the mechanical arm. The other end is wound around section B in the opposite direction, passed around a pulley at the top of the other supporting steel frame, and connected to another rope clip on the mechanical arm. Both ends remain taut. When the electric winch rotates forward, the wire rope is pulled and the mechanical arm tilts to one side; when it rotates reversely, the mechanical arm tilts to the other side.

[0021] The bottom of the mechanical arm 2 is connected to the fixed seat 10 through the rotating shaft I9, and the fixed seat is fixed on the base 14. Rope buckles 11 are respectively provided on both sides of the top of the mechanical arm; slide rails 7 are respectively fixed on the longitudinal sides of the mechanical arm, and a slider 8 is provided on the slide rail. The slider half surrounds the mechanical arm, and the rear outer edge of the slider is integrally fixed with a welded nut 16; the front side of the slider is open, and the rotating seat 17 is installed at the opening and is connected to the slider through the rotating shaft II18; the lower pressure roller 4 is installed on the rotating seat. It also includes a pneumatic rod 19, which is respectively provided on both sides of the slider. The protruding end of the pneumatic rod is connected to the rotating shaft II, and the other end of the cylinder is fixed to the slider through a reinforcing plate 20. A screw rod 15 is installed at the back of the mechanical arm. The screw rod and the nut are matched and installed. The screw rod can be rotated by a handwheel 6 or a motor. The screw rod rotates, driving the slider to move up and down.

[0022] Working process of the present invention:

[0023] By manipulating the electric winch, the steel wire rope, under the action of the positive rotational force, begins to pull the mechanical arm along the fulcrum and tilt toward the conductive tube. The lower pressure roller directly acts on the conductive tube 5. As the conductive tube is pressed down, the lower pressure roller rotates along the surface of the conductive tube until the conductive tube is pressed down to a certain position, facilitating the assembly of the conductive tube. After the conductive tube is pressed down and fixed, the electric winch is controlled to move, and the steel wire rope, under the action of the negative rotational force, pulls the mechanical arm back to the vertical position.

[0024] According to the actual situation, the tilt position of the mechanical arm and the flipping of the lower pressure roller can be manually controlled.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
