Description

All-round fixed connection ladder

technical field

The utility model relates to an omnidirectional fixed connection ladder.

Background technique

In the prior art, the operation of personnel climbing and pruning branches adopts a common aluminum alloy single ladder; or adopts foot buckles to climb cement poles, and personnel work on cement poles for a long time.

There are the following problems in this way:

1. The height of the ordinary aluminum alloy single ladder is limited and cannot be erected to the trimming height.

2. Ordinary aluminum alloy single ladders need to be supported by personnel during use to prevent sliding and collapsing;

3. In the process of climbing trees, people will encounter dead branches, rotten branches, and broken branches, which will cause people to fall;

4. When using the foot buckle on the cement pole, the staff is prone to fatigue when using the foot buckle for a long time, thereby reducing work safety;

Utility model content

The technical problem to be solved by the utility model is to provide an all-round fixed connection ladder, which is light and easy to use, and can safely send people to specified positions.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: an omnidirectional fixed connection ladder, which is characterized in that it includes a hollow aluminum alloy column, and the left and right sides of the column are staggered with aluminum alloy ladders, and the upper and lower sides of the column The end is provided with a tightener.

Preferably, the ladder is a hollow aluminum alloy beam arranged perpendicular to the column, the beams on the column are all located on the same plane, and an aluminum alloy diagonal brace is provided between the lower side of the beam and the column.

Preferably, the tightener includes a vertical plate, a horizontal plate is vertically arranged on the upper and lower sides of the vertical plate, an arc-shaped opening is arranged in front of the horizontal plate, and a row of teeth is arranged in the arc-shaped opening.

Preferably, a connecting column is provided in the middle of the rear side of the vertical board to connect with the vertical column, and at the same time, a side connecting column is respectively provided on the left and right sides above and below the central connecting column to connect with the vertical column on the rear side of the vertical board.

The connecting ladder of the utility model is composed of a column, an aluminum alloy ladder and a tightener, and realizes the following functions:

1. Aluminum alloy climbing ladder: It can effectively enable people to climb to the tree pruning position, and during the pruning process, it can avoid the danger of people falling due to being unable to stand or stepping on dead branches, rotten branches and broken branches;

2. Tightener: It can securely fix the aluminum alloy ladder on the tree trunk (or cement pole), so as to ensure that the aluminum alloy ladder does not move or fall off during the climbing or staying process, so as to protect the safety of the workers;

Thereby, the utility model has the advantages of:

1. The utility model avoids the danger of personnel falling from stepping on dead branches, rotten branches and broken branches during the work of pruning trees;

2. The utility model solves the problem that the ordinary aluminum alloy single ladder is insufficient in length and cannot be erected below the working place, which causes difficulties and safety factors for the workers to pass up and down.

3. The utility model greatly reduces the fatigue of the staff who use the foot buckle on the cement pole for a long time, and improves the safety factor of the operation;

4. The utility model avoids the dangers existing in the climbing and staying process of the climbers in the process of tree pruning (work on the cement pole), and ensures the safety of the workers as much as possible.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:

Fig. 1 is a front view of the utility model;

Fig. 2 is a top view of the utility model;

Fig. 3 is a side view of the utility model.

Detailed ways

As shown in Figures 1 to 3, it is an embodiment of the omnidirectional fixed connection ladder of the present invention, which includes a hollow aluminum alloy column 3, and the left and right sides of the column are staggered with aluminum alloy ladders 2, and the up and down of the column Tighteners 1 are arranged at both ends.

The ladder 2 is a hollow aluminum alloy beam arranged vertically to the column. The beams on the column are all located on the same plane, and an aluminum alloy diagonal brace 20 is arranged between the lower side of the beam and the column. The upright column 3 is provided with a pair of crossbeams 2 staggered left and right adjacent to the tensioner 1 on the lower side of the upper tightener 1, and the pair of crossbeams 2 are abutted together.

The tightener 1 includes a vertical plate 10, a horizontal plate 11 is vertically arranged on the upper and lower sides of the vertical plate, an arc-shaped opening is arranged in front of the horizontal plate, and a row of teeth is arranged in the arc-shaped opening. The middle part of the rear side of the vertical plate is provided with a connecting column 12 to be connected with the column, and the rear side of the vertical plate 10 is respectively provided with a side connecting column connected with the column 3 at the upper and lower left and right sides of the central connecting column 12 . The left and right sides of the upper and lower horizontal plates 11 are respectively connected by a bolt 13 .

The utility model provides a new tool with high efficiency and low risk for the application in the environment of pruning trees in the vicinity of transmission lines and working on cement poles for a long time. Using this tool, people can be safely sent to the specified position. It is convenient for personnel activities, and avoids the danger of personnel falling caused by operators stepping on dead branches, rotten branches, and broken branches during the tree trimming process, and the operator is prone to fatigue when using the foot buckle on the cement pole for a long time, thereby reducing work safety.

The total length of the utility model is 1.7 meters, which can be freely interspersed among the branches; the total weight is 9.7KG, and a person can change position and fix at high altitude with one hand; the total load-bearing is 150KG, which ensures that a person can safely stand on it. related work. The main components of the utility model are the column 3, the beam 2, the brace 20 and the tightener 1 are all aluminum alloy structures, and are connected by welding.
