Description

Rotary arm pole switch lifting bracket

technical field

The invention relates to a hoisting device, in particular to a pivoting arm type pole-mounted switch hoisting bracket.

Background technique

In the maintenance process of distribution lines, it is very common to install or replace a 10kV pole-mounted switch. The traditional new installation or replacement of a pole-mounted switch is mainly completed by the following four methods, namely: crane hoisting, sliding rope installation, double Pole mount and single pole mount.

In the prior art, crane hoisting is the most commonly used method. Although this method can be completed, it is easily restricted by the terrain, especially in farmland, where cranes cannot be used for operations, and there are still high construction costs and installation risks in crane hoisting construction. Disadvantages; the selection of tools such as sliding ropes, double poles and single poles is not restricted by the terrain, and the construction cost is low, but these tools have limitations in the selection of lifting points, high risk of work and inability to carry out work.

Contents of the invention

Aiming at the deficiencies of the prior art, the present invention provides a pivoting arm type pole-mounted switch lifting bracket. The lifting bracket prepared by the invention can freely pivot the arm, freely adjust the elevation angle, and can be used with various types of equipment such as sliding ropes or gear three-purpose machines. Lifting tools are used to overcome the deficiencies of the prior art, and the whole set of brackets has fewer accessories, and has the advantages of flexible installation, low construction cost, portability and practicality.

Technical scheme of the present invention is as follows:

The pivoting arm type column switch lifting bracket includes a boom, a wire rope and a fixed hoop. The fixed hoop includes an upper fixed hoop and a lower fixed hoop. The upper fixed hoop is connected to the boom through a wire rope , the lower fixing hoop is connected to the lower end of the boom, and the boom is provided with a hook, wherein the upper fixing hoop and the lower fixing hoop are fixed on the pole.

On the basis of adopting the above technical solutions, the present invention can also adopt the following technical solutions:

The total length of the boom is 2.06m.

The connection point between the lower fixing hoop and the lower end of the boom is a two-way rotation connection point.

The hook is provided with a pulley device or a gear three-purpose machine.

The beneficial effects of the present invention are:

1. Compared with the traditional lifting method, the lifting bracket of the present invention can lift the switch vertically without the need for staff to pull it laterally, which not only reduces the number of ground coordinators, but also greatly improves the safety of work.

2. After the hoisting bracket of the present invention adopts the design that the connection between the lower fixed hoop and the lower end of the boom is a two-way rotating connection, after the switch is hoisted to the horizontal height of the installation position, the boom can be rotated to send the switch directly To the installation location, safe and fast.

3. The hoisting bracket of the present invention can adjust the lifting angle of the boom by adjusting the distance between the upper and lower fixed hoops and changing the length of the soft-connected steel wire rope, making it more convenient to replace the single-rod bracket switch.

4. The lifting bracket of the present invention has the advantages of reliable operation, easy maintenance, long service life, low manufacturing cost, readily available raw materials, and simple processing technology.

Description of drawings

Fig. 1 is a schematic structural diagram of a lifting bracket for a switch on a pole with a pivoting arm according to an exemplary embodiment of the present invention.

Marks in the figure: 1-upper fixed hoop, 2-lower fixed hoop, 3-boom, 4-wire rope, 5-hook, 6-pulley device, 7-switch.

Detailed ways

Referring to the accompanying drawings, the present invention will be described in detail in combination with specific embodiments.

Example

Referring to Fig. 1, that is, the structural schematic diagram of the switch lifting bracket on the pivoting arm type pole of the present invention, including the boom, the steel wire rope and the fixed hoop, the fixed hoop includes an upper fixed hoop 1 and a lower fixed hoop 2, and the upper fixed hoop 1 is connected to the boom 3 through a wire rope 4, and the lower fixed hoop 2 is connected to the lower end of the boom 3 through a two-way rotating connection point. The boom 3 is provided with a hook 5, wherein the total length of the boom 3 is 2.06m , the upper fixed hoop 1 and the lower fixed hoop 2 are fixed on the pole, and the hook 5 is provided with a pulley device 6 .

When in use, fix the upper fixed hoop 1 and the lower fixed hoop 2 on the electric pole, and then connect the lower end of the boom 3 to the lower fixed hoop 2 for two-way rotation, and then connect the upper fixed hoop 1 through the wire rope 4 and The booms 3 are connected, the pulley device 6 is hung on the hook 5 of the boom 3, the switch 7 can be hoisted, and after the switch 7 is hoisted to the level of the installation position, the boom 3 can be rotated to lift the switch 7 directly sent to the installation location, wherein, the spacing of the upper and lower fixed hoops and the length of the wire rope 4 can be freely adjusted according to the actual working conditions.

The above are only preferred implementations of the present invention. It should be noted that the above preferred implementations should not be regarded as limiting the present invention, and the scope of protection of the present invention should be based on the scope defined in the claims. For those skilled in the art, without departing from the spirit and scope of the present invention, some improvements and modifications can also be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
