Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to a cable entry wire puller. Background Art

[0002] At present, in the process of cable laying in residential areas, the construction of cables entering unit buildings (cables entering households) basically adopts manual pulling of traction ropes to pull the cables from the wire protection tube into the room;

[0003] However, manual wire pulling is inefficient, time-consuming and laborious, and requires the coordination of multiple workers, which results in slow construction efficiency and a long construction period. Secondly, with this wire pulling method, workers will not pull the wire at high altitudes or at an angle perpendicular to the protective tube in order to save effort. This results in the direction of the manual pulling force being inconsistent with the direction of the cable protective tube entering the house, causing damage to the traction rope and cable from friction with the tube wall. Utility Model Content

[0012] By setting up a pulling wire mechanism, etc., the traction rope and the protective tube can be pulled in a vertical state. At the same time, the gear labor-saving structure of the hand-cranked winch reduces the force required for pulling the rope, effectively improving the traction efficiency of the traction rope, improving construction efficiency, ensuring that the direction of the manual dragging force is consistent with the direction of entry of the cable protection tube into the house, and reducing damage caused by the friction between the traction rope and the tube wall.

[0026] As a preferred solution of the utility model,

[0027] The wire pulling mechanism comprises:
