Description

Overhead wire crossing device

technical field

The invention specifically relates to an overhead conductor crossing device.

Background technique

When erecting power conductors, it is often necessary to pass through some facilities that cannot be directly passed through (such as high-voltage power lines, railways, expressways, etc.). When the conductor is erected, the lifting and tensioning of the conductor must also pass through the pulley. In the past production, it was found that when the conductor passes through the spanning frame, the resistance is very large. However, the general spanning frame is erected with bamboo poles or wooden poles, and the conductor passes directly. The top of the spanning frame, due to the weight of the wire itself and the pulling force of the wire, not only causes the wire to be damaged by the force and breaks the wire, but also causes a collapse accident due to excessive force on the spanning frame. In addition, when the wire is erected, most of them use For hanging pulleys, when the wires are tightened, the wires need to be lifted over the cross arm. When lifting, due to insufficient lifting force or slipping, wire drop accidents are often caused.

detailed description

In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Embodiment one

As shown in Fig. 1 and Fig. 2, the overhead wire crossing device includes a cross member 1 and a cross arm 10, and the cross arm 10 is fixedly installed on the pole, and also includes a pulley frame 2, a pulley 3, a fixing device 4 and Wire anti-jumping device 5, the pulley frame 2 is horizontally placed on the horizontal material 1, the pulley frame 2 is fixed on the horizontal material 1 by the fixing device 4, and the pulley 3 is fixed in the pulley frame 2 by nailing , the wire anti-jumping device 5 is arranged on the top of the pulley frame 2 through a hinge.

The upper end of the pulley frame 2 is a positive U-shaped structure, the fixing device 4 is a U-shaped clamp iron 6, and the U-shaped clamp iron 6 is an inverted U-shaped structure, and the U-shaped clamp iron 6 is buckled upside down on the pulley frame 2. The top is fixed on the cross bar 1 by bolts.

The wire anti-jumping device 5 includes a gear lever 8 and a lock catch 9, the gear lever 8 is pierced with a rollable round tube, and one end of the gear lever 8 is fixed on the top of the U-shaped side of the pulley frame 2 through a hinge. The other end of the gear bar 8 is fixed on the top of the other side of the U-shaped pulley frame 2 by a lock catcher 9 .

The device also includes an operating rod, which is a wringer rod.

The cross member 1 is made of high-strength square glass fiber composite insulating material.

When the device is used as a wire crossing frame sliding wire, when the wire is placed on the top of the crossing frame, use the operating rod to put the wire on the pulley, and use the operating rod to buckle the lock 9 to prevent the wire from jumping out when the wire is pulled. , so that the wire can be easily pulled over the spanning frame. After the wire is spanned, the lock 9 is pushed away with the operating rod, and the wire is pushed out of the pulley 3 and placed on the cross member 1 to make the wire break away from the device, so that it will not It affects the take-off and landing of the wire, which not only reduces the resistance of the wire, but also does not damage the wire, increases the service life of the wire, reduces the pressure on the spanning frame when pulling the wire, and prevents the wire from running out of the pulley frame.
