Description

Enclosed pulley for pole and tower cable deployment

technical field

The invention belongs to the technical field of electric power transmission, and in particular relates to a closed pulley for tower and cable deployment used for operation on power transmission lines.

Background technique

During the operation and maintenance of the power system, operators are often required to replace cables online, and pulleys are required when laying out cables on poles and towers. In the past, ordinary pulleys used for cable replacement may easily cause the cable protection layer to be scratched by the pulley wall.

Contents of the invention

The present invention aims at the problems existing in the above-mentioned prior art, and provides a closed type block for tower cable deployment, which solves the problem that the block in the prior art easily causes the cable protection layer to be scratched.

Technical scheme of the present invention is as follows;

The fixed frame is provided with vertical pulley I, vertical pulley II and horizontal pulley, and one end of vertical pulley I and vertical pulley II is respectively connected with two ends of horizontal pulley, and the other end of vertical pulley I and vertical pulley II There is a closed door between them; one side of the fixed frame is provided with a connecting mechanism.

The radians of described vertical pulley I, vertical pulley II and horizontal pulley are equal.

Described vertical pulley 1 is fixedly connected with horizontal pulley.

The vertical pulley II is movably connected with the horizontal pulley through a rotating shaft.

Described sealing door comprises column and hook, and column is arranged on the fixed frame, and one end of hook is fixed on the column, and the other end of link is hooked on the pulley axle of vertical pulley II.

The connecting mechanism includes a fixing ring and a fixing belt, the fixing ring is arranged on the side wall of the fixing frame, and the fixing ring is connected with the fixing belt.

The fixing ring and the fixing belt include an upper fixing ring, a lower fixing ring, an upper fixing belt and a lower fixing belt respectively.

The present invention has the following advantages:

The tower cable deployment closed block consisting of three pulleys is light and flexible when laying out the cables on the tower. Through the rotation of three pulleys with equal arcs, the problem of cable scratches is eliminated, and the quality of cable construction is improved. And the vertical pulley II is a movable pulley, which can prevent the cable from popping out of the pulley. At the same time, the pulley is installed on the pole tower through the fixing belt, which is convenient and flexible for installation.

Detailed ways

Example

As shown in Figure 1-2, the aluminum alloy fixing frame 5 is provided with vertical pulley I, vertical pulley II and horizontal pulley 6 with equal radians, and vertical pulley I11, vertical pulley II9 and horizontal pulley are respectively set in Type pulley shaft I 15, vertical pulley shaft II 14 and horizontal pulley shaft 7; one end of vertical pulley I and vertical pulley II is connected with the two ends of horizontal pulley respectively, and the other end of vertical pulley I and vertical pulley II A closed door is arranged between one end; a connecting mechanism is arranged on one side of the fixed frame.

Described vertical pulley 1 is fixedly connected with horizontal pulley. Described vertical pulley II is movably connected with horizontal pulley by rotating shaft 8.

Described sealing door comprises column 12 and hook 13, and column is arranged on the fixed mount, and one end of hook is fixed on the column, and the other end of hook is hooked on the pulley axle of vertical pulley II.

Described connection mechanism comprises fixing ring and fixing band, and fixing ring is arranged on the side wall of fixing frame, and fixing ring connects fixing band; Described fixing ring and fixing band comprise upper fixing ring 1, lower fixing ring 4 and upper fixing ring respectively. Fixing belt 2, lower fixing belt 3.

Before using the tower cable to deploy the closed tackle, use the fixed soft belt to fix the tackle at the suspension point of the tower, open the sealing door and the movable vertical pulley II, use the transfer rope to lift the cable into the tackle, close the sealing door and Vertical pulley II. At this time, the traction machine pulls the cable, and proceeds at a uniform speed along the line direction, so that the cable and the pulley are kept at 90 degrees to prevent the cable from being scratched. When the cable moves, the three pulleys rotate, and the pulley rotates with the cable. Put a pulley, fix and disassemble through the fixed soft belt, if multiple cables can hang multiple pulleys per base tower, arrange them up and down for deployment.
