Description

Fixed pulley device for cable erection

technical field

The utility model specifically relates to a fixed pulley device for cable erection, which belongs to the technical field of cable erection equipment.

Background technique

The construction of overhead optical cables is roughly divided into the following steps: preparation → routing engineering → optical cable erection → optical cable connection → project acceptance. At present, the method of overhead laying of optical cables mostly adopts the fixed pulley traction method, and the large pulleys for laying optical cables are fixed on the poles at the upper and lower leads. Hang a small pulley (guide pulley) every 10-20m on the hanging wire in each pole, and put the traction rope into the small pulley. Then, prepare the traction head, connect the traction rope with the optical cable, and prepare for deployment. When manual traction is used, the optical cable reel is manually pushed to release the optical cable gradually, and then one person is set up on every other pole for auxiliary traction (if necessary, a guide pulley is installed on the corner pole). Gradually tighten the traction rope at the traction end to release the optical cable slowly. In order to fully ensure the safety of the optical fiber, three contact telephones should be installed at the cable release end, cable take-up end and optical cable pulling head of the optical cable line, and the communication should be kept smooth at all times. When the single-reel optical cable is long, it is generally deployed in two stages: that is, after the first half of the reel is deployed, the word "8" is placed on the spot, and then the second half of the reel is deployed in another direction. When mechanical traction is used, the mechanical traction host should be placed at the cable receiving end, and the auxiliary traction machine should be placed at an appropriate position for erecting the route. Set up the optical cable reel at the cable release end, manually push the optical cable reel to gradually release the optical cable from the top of the reel, and use machinery instead of manual traction to achieve the purpose of laying optical cables.

This method needs to arrange more pulleys, and requires more operators, which is inconvenient.

The utility model is further provided with an arc-shaped film in the hoop, and the arc-shaped film can be provided with various thicknesses. This is because the diameters of the wire rods are different, but in order to ensure the service life and strength of the device, metals, especially metals, are generally used. Steel, the diameter is inconvenient to adjust, and it can be adapted to the installation operation of poles with different diameters in the form of built-in film, and the built-in film can also play a non-slip effect, further improving the firmness of the installation.

Compared with the prior art, the utility model has the following beneficial effects.

The fixed pulley of the utility model can realize the installation of the fixed pulley without climbing poles, the firmness and safety of the installation are easy to control, and the work intensity and risks are reduced. The fixed components, sleeves, hydraulic rods, etc. can be disassembled and assembled, which is convenient for carrying, transportation and storage.

The lock of the utility model is a movable lock, which is used to temporarily fix the cable head (cable or optical cable, etc.). The cable is removed from the carabiner and passed through the fixed pulley to prepare it for pulling. In the whole process, the labor is only responsible for installing the device at the lower part of the wire rod through the fixed components, operating the hydraulic rod button and cable traction and positioning. The work is low in intensity and accurate and controllable.
