detailed description

The present invention will be further described in detail below in conjunction with specific embodiments.

A special drainage wire fixed lock rod for disconnecting the lead wire by the operating rod method of live work, its structure is shown in Figure 1, including an insulating rod 1, a hook and a lead wire locking mechanism; the hook is arranged on the top of the insulating rod for locking the entire fixed The rod is suspended on the wire; the lead wire locking mechanism is clamped in the middle of the insulating rod through the hoop 2 to lock the drain wire; the distance between the hook and the lead wire locking mechanism is adjusted to an electrical safety distance through the hoop to ensure the live wire Safety of workers and equipment. In the present invention, the insulating rod, the hook and the lead wire locking mechanism are all made of epoxy resin insulating material, and the insulating rod can also be a hollow telescopic rod.

The structure of the hook is shown in Figure 1, including an inverted U-shaped main body 5, and a locking hook mechanism is arranged inside the inverted U-shaped main body 5, which is used to lock the wire and prevent the hook from loosening and sliding.

The structure of the lock hook mechanism is shown in Figure 2, including two frame-shaped deadbolts 61 symmetrically arranged in the inverted U-shaped main body 5, an insulating small rope and a locking spring, and the frame-shaped deadbolt can be changed by pulling the insulating small rope. Position inside the inverted U-shaped body to release the wire; the locking spring is not only used to clamp the wire, but also to reset the frame lock tongue after the wire is released.

The frame-shaped locking tongue 61 includes a locking panel, a guide plate and a positioning plate, and the guide plate is fixedly arranged on the top of the locking panel. The locking panel is set as a concave arc surface, so that the two frame-shaped lock tongues can wrap the wires to prevent damage to the wires; the positioning plate is fixed at the bottom of the locking panel, and one end of the insulating rope is connected to the outer end of the guide plate. Fixed connection, the other end of the small insulating rope passes through the insulating rod and extends out of the insulating rod; the outer end of the positioning plate is at the bottom of the inverted U-shaped main body through the pin shaft; the length of the positioning plate is shorter than the length to the guide plate; the return spring The bottom end of the back spring is fixed on the inverted U-shaped main body by a positioning rod 62, and the top end of the back-moving spring is fixedly connected with the bottom end surface of the guide plate. When it is used to clamp the wire, the wire enters from the bayonet between the bottoms of the two frame-shaped lock tongues into the arc surface of the two frame-shaped lock tongues, and the wire can be firmly clamped in the hook mechanism; When it is used to release the wire, when the small insulating rope is pulled down, the top of the frame-shaped deadbolt opens and the insulating rod is pushed upward to release the wire. After the wire is released, loosen the small insulating rope, and the frame-shaped deadbolt can Return to the original position under the action of the return spring.

In this embodiment, the connection between the positioning plate and the locking panel is set as an arc-shaped structure that is convenient for wires to enter, and can also avoid damage to the wires; the head of the guide plate can be set as a transitional arc-shaped structure corresponding to the arc at the top of the inverted U-shaped main body .

The lead wire locking mechanism is used to clamp the drainage wire. Its structure is shown in Figure 1. It includes a vertical plate fixed on the outer end surface of the hoop. The top of the vertical plate is fixedly connected with a curved surface fixing groove 3 with the opening facing downward. The bottom end is vertically provided with a connecting plate, and an upright cylindrical locking spring 4 is arranged between the connecting rod and the curved surface fixing groove. The small insulating rope compressed or released by the cylindrical locking spring is led out after passing through the inner channel of the cylindrical locking spring, the connecting plate and the insulating rod. When used to clamp the drainage wire, pull down the small insulating rope, and the cylindrical locking spring moves downward to open the gap between the locking cap and the curved surface fixing groove. After the drainage wire enters the curved surface fixing groove, loosen the small insulating rope. The locking cap clamps the drainage wire in the fixed groove on the curved surface under the action of the cylindrical locking spring, which reliably ensures that the drainage wire will not loosen and swing.

When the present invention is in use, first adjust the position of the hoop and the lead wire locking mechanism on the insulating rod according to the electrical safety distance; then, fix the drain wire in the lead wire locking mechanism by operating the small insulating rope on the lead wire locking mechanism, Then operate the hook to hang the fixed lock bar on the drained wire as a whole, while ensuring that the drain wire and the hook will not loosen and swing, and at the same time ensure a safe distance between the two, providing safety for operators. Reliable working environment.
