Embodiment 1

[0027] like figure 1 and figure 2 As shown, the invention provides a construction method for laying an optical cable with a pulley device, the method comprising the steps of:

[0028] Step 1: Set up safety facilities around the construction manhole;

[0029] Place safety cones, safety warning signs, etc.;

[0030] Step 2: Place a pulley device around the well, place the pulley device on the well in the direction of laying the optical cable, and buckle the base on the well ring;

[0031] Step 3: Adjust the angle of the pulley device, and put the optical cable on the pulley 4;

[0032] According to the force direction of the optical cable construction, adjust the angle of the U-shaped block 2 of the pulley device, put the optical cable on the pulley 4, and the pulley 4 rotates through the bearing of the bearing screw 5 in the middle of the U-shaped block 2;

[0033] Step 4: Lay optical cables in the construction pipeline to complete the construction.

[0034] Among them, b...

Abstract

The invention discloses a pulley device and a construction method for optical cable distribution thereby. The pulley device comprises a base 1, U-shaped block set 2, a cylindrical connecting block 3, a pulley 4, a screw 5 with bearings, clamping plates 6 and a rotor 7. The base 1 is connected with the U-shaped block set 2 through the cylindrical connecting block 3 comprising an upper portion and a lower portion. The upper portion is clamped on the U-shaped block set 2. The lower portion is fixedly welded to the base 1. The U-shaped block set 2, the pulley 4 and the clamping plates 6 are fixedly connected with the screw 5 with the bearings through nuts. The pulley 4 is arranged between the U-shaped block set 2 and sequentially connected with the screw 5 with the bearings. The screw 5 with the bearings penetrates the U-shaped block set 2, the pulley 4 and the clamping plates 6 and is tightened through rotation of the nuts on two sides of the same. Two ends of the rotor 7is fixed on the clamping plates 6 through screws and the nuts. By the use of the pulley device, the optical cables are less affected by friction and protected, and the optical cable distribution requires fewer resources and shortened time.

Description

technical field [0001] The invention relates to a pulley device and a construction method for laying optical cables thereof, belonging to the technical field of machinery. Background technique [0002] At present, in the pipeline construction link, the pulley device is generally used for laying cables, and the cable pulley is suitable for mechanical laying. However, the mechanical deployment is evenly stressed and the traction direction is single. The optical cable can only be deployed manually according to the characteristics of the optical cable itself. Manual deployment generally places the optical cable in the pipeline, and the optical cable directly penetrates the wellhead and is deployed downward. However, during the laying process, the optical cable will constantly rub against the outside of the wellhead ring, causing the optical cable to be subject to great lateral pressure and friction, which invisibly makes the optical cable a great safety hazard during the constru...
