Description

A utility pole climbing ladder

technical field

The utility model relates to the field of electric power facilities, in particular to an electric pole climbing ladder.

Background technique

The foot buckle is a special tool for creeping poles in the process of electric power construction. It is generally made of high-strength seamless pipes, and after heat treatment, it has the characteristics of light weight, high strength, good toughness, good adjustability, lightness and flexibility. The foot buckle generally includes an arc rod and a pedal. When using, put the foot on the pedal and fix it with a safety belt, one for each foot. When climbing the pole, the arc pole is stuck on the pole, and the lever is used. With the help of the body's own weight, the arc-shaped rod is tightly fastened on the pole, which generates a large friction force, which makes it easy for people to climb. The foot buckle needs to use both hands to hold the pole for climbing, so there is still the disadvantage of difficult climbing, and because the foot pedal is fastened to the foot through the seat belt, once the seat belt is broken, or the foot pedal is broken, There are still great security risks.

The utility model is achieved through the following technical solutions:

An electric pole climbing ladder is characterized in that it is formed by connecting a plurality of ladder sections, the ladder section includes two vertical cylinders, the two vertical cylinders are connected by two connecting cylinders, and a set between the two connecting cylinders is provided. There are several pedals; the connecting cylinder at the upper end is provided with at least one clamp; the vertical cylinder is provided with a through hole in the up-down direction, and a T-shaped connecting rod is arranged in the through hole; one of at least two ladder sections An arc-shaped rod is hinged on the vertical cylinder, and the inner side of the arc-shaped rod is provided with anti-slip thorns.

A horizontal plate is arranged below the hinge point between the arc-shaped rod and the vertical cylinder.

The clamp is hinged with the connecting cylinder.

The clamp is connected with the connecting cylinder through an iron chain.

The vertical cylinder is provided with a handrail.

Safety belts are provided on the ladder sections.

The length of the ladder section is 1-1.5 meters.

Both ends of the connecting cylinder and the pedal are respectively provided with U-shaped notches.

The beneficial effects of the present utility model are:

Several sections of the ladder are assembled together on site through clamps and T-shaped connecting rods to form a whole. The height can be increased arbitrarily from the lower end. Climbing the ladder to the top for operation is more labor-saving and has a higher safety factor.

In the figure, 1 vertical cylinder, 2 connecting cylinder, 3 pedals, 4 through holes, 5 T-shaped connecting rods, 6 clamps, 7 handrails, 8 arc rods, 9 anti-slip spikes, 10 horizontal plates, 11 seat belts, 12 irons Chain, 13 U-notch.

Detailed ways

The accompanying drawings are specific embodiments of the utility model. As shown in Figure 1 to Figure 4, this kind of telephone pole climbing ladder is composed of several ladder sections. The length of the ladder section is preferably 1 meter to 1.5 meters. The clamps 6 are connected, and the number of clamps 6 is preferably two. Each ladder section includes two vertical cylinders 1. The two vertical cylinders 1 are connected by two connecting cylinders 2, and the clamps 6 are connected to the upper connecting cylinder 2. Hinged or connected by iron chains 12, there are several pedals 3 between the two connecting cylinders 2, the vertical cylinder 1 and the pedals 3 form a small ladder, and each vertical cylinder 1 has a through hole 4 in the up and down direction. 4. There is a T-shaped connecting rod 5; in all the ladder sections, at least one of the two ladder sections is hinged with an arc-shaped rod 8 on one of the vertical cylinders 1. The arc-shaped rod 8 is like a foot buckle, and the arc-shaped rod The inner side of 8 is an anti-slip thorn 9; the lower part of the hinge point between the arc-shaped rod 8 and the vertical cylinder 1 is a horizontal plate 10.

A handrail 7 is welded on the vertical cylinder 1 .

Safety belts 11 are installed on the ladder sections.

In order to facilitate the up and down of the T-shaped connecting rod, there is a U-shaped gap 13 at both ends of the connecting cylinder 2 and the pedal 3, and the U-shaped gap 13 can accommodate the upper end of the T-shaped connecting rod 5 to pass through.

The vertical cylinder 1, the pedal 3, the connecting cylinder 2, the T-shaped connecting rod 5, and the horizontal plate 10 are all made of metal, such as stainless steel.

Use process: First, use the ladder section with the arc rod 8, put the arc rod 8 on the utility pole, and push it up along the utility pole. At this time, the arc rod 8 is under its own On the telephone pole, but it is already in a horizontal state, and it is placed on the horizontal plate 10, so it does not affect the rise of the ladder section and rises to a certain height. At this time, the T-shaped connecting rod 5 of the previous ladder section is on the T-shaped connecting rod. Under the action of its own gravity, 5 extends from the vertical tube 1, and then connects the next ladder section. If the next ladder section also has an arc-shaped rod 8, first set the arc-shaped rod 8 to the telephone pole, and then Insert the T-shaped connecting rod 5 in the vertical cylinder 1 of the previous section into the vertical cylinder 1 of the next ladder section, and clamp the clamp 6 on the next ladder section to the connecting cylinder at the lower end of the previous ladder section. 2, at this time, the upper and lower vertical cylinders 1 should be pushed together, so that the upper vertical cylinder 1, the T-shaped connecting rod 5 and the lower vertical cylinder 1 become one, so that the two ladder sections become one. , Connect the ladder sections in sequence according to the height of the utility pole, so that you can reach the top of the utility pole to facilitate the operation. After installation, pull the ladder section downward, so that the arc-shaped rod 8 is inclined and hung on the utility pole, and a temporary climbing ladder is formed. , the construction personnel can hang the seat belt 11 to climb, and the seat belt 11 can be replaced in the middle.

Except for the technical features described in the description, other technical features are known technologies by those skilled in the art.
