In addition, a middle metal joint of the insulation single-column ladder is in a threaded connection mode, four circular fixing rings are designed in the middle metal joint, and temporary drawing wires can be added when necessary.

Description

An insulated single-column ladder

technical field

The present invention relates to an insulated single-column ladder.

Background technique

In the prior art, in the treatment of transmission line defects in the conductor, the insulating ladder is often used to hang the conductor on the conductor, and the personnel climb to the defect of the conductor, and then wind the conductor with aluminum wire or repair the pre-twisted wire to make the conductor meet the requirements of power transmission. line operating conditions.

But there is following defective in prior art:

1. Handle the defects on the wires in the gear with broken strands, and the operation of the soft ladder cannot be suspended after checking.

2. Standing up or two or more people on the same wire, the operation of the ladder cannot be suspended after checking.

Contents of the invention

The technical problem to be solved by the present invention is to provide an insulating single-column ladder, which has a wide range of applications and can be used when the soft ladder cannot be suspended.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: an insulating single-column ladder, comprising a hollow cylindrical tube body, the tube body is symmetrically arranged with ladder rods perpendicular to the tube body along the axial direction, and the tube body There are four hanging rings evenly distributed around the circumference of the top.

Preferably, the ladder rod is provided with an anti-skid groove.

Preferably, the distance between two vertically adjacent ladder rods is 35cm.

Preferably, the hanging ring is connected to the pipe body through a movable block, and a 360-degree rotating structure is provided between the movable block and the pipe body.

Preferably, the pipe body includes at least two unit sections, and two adjacent unit sections are threadedly connected by metal joints.

Preferably, four fixed rings are evenly distributed around the circumference of the pipe body above the metal joint.

Preferably, the pipe body and the ladder bar are integrally formed with epoxy resin.

The pipe body of the insulating single-column ladder of the present invention is provided with ladder rods perpendicular to the pipe body symmetrically along the axial direction for climbing. The ring realizes the function of connecting with the insulated rope. At the same time, each hanging ring passes through the movable block, and the connection part can be rotated 360 degrees to balance the uneven force of the four-side insulating pull wire. In addition, the metal joint in the middle of the insulated single-column ladder adopts the form of threaded connection, and four fixed rings are designed here, and temporary pull wires can be added if necessary.

Thereby the advantage of the present invention after adopting above-mentioned technical scheme is:

1. The insulated single-column ladder can effectively fill in the wires in the file. After checking, the insulated soft ladder cannot be suspended for work, and the method for emergency handling of defects in live work has been added.

2. The insulated single-column ladder is easy to operate, which greatly reduces the physical energy consumption of live workers when climbing the ladder (compared to climbing the soft ladder).

3. The insulated single-column ladder adopts the form of four-side pull wires, which improves the safety of the operation and greatly improves the operation efficiency.

4. The insulated single-column ladder also improves the ability of live work to deal with defects urgently, reasonably solves the practical problems in production, and further improves the management system of live work equipment for transmission lines.

Description of drawings

The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

Fig. 1 is a schematic diagram of the structure of the present invention;

Fig. 2 is a schematic diagram of the second structure of the present invention.

Detailed ways

Figure 1 and Figure 2 show the specific structure of the insulated single-column ladder of the present invention.

It includes a hollow columnar tube body 1, and the tube body 1 is symmetrically arranged with ladder rods 2 perpendicular to the tube body along the axial direction, and four hanging rings 3 are evenly distributed around the circumference of the tube body top. The ladder bar 2 is provided with an anti-skid groove 20 . The distance between two adjacent ladder bars up and down is 35cm. The hanging ring 3 is connected to the pipe body through a movable block 30, and a 360-degree rotating structure is arranged between the movable block and the pipe body. The pipe body includes at least two unit sections, and the adjacent two unit sections are threadedly connected by metal joints 4 . . Four fixed rings 40 are evenly distributed around the circumference of the pipe body above the metal joint. The pipe body and the ladder bar are integrally formed with epoxy resin.

The insulating single-column ladder of the present invention is an equipotential man-carrying tool. It is connected by multi-section epoxy resin pipes through metal joints. After the four temporary stay wires on the top of the ladder are stabilized, personnel climb from the ground to the wires to deal with defects, so it can be used when the soft ladder cannot be suspended.
