[0001] The present application relates to the field of cable conveying equipment, and in particular to a double-screw conveyor. Background Art

[0002] A cable conveyor is a device used to automatically, quickly, and safely transport and install cables continuously. Its core principle is to use friction to pull the cables so that they can be laid along a predetermined path. It plays an important role in modern industrial production, especially in the power, telecommunications, construction, manufacturing and other industries.

[0003] At present, most cable conveyors on the market are single-screw conveyors, which include upper and lower clamping types and horizontal clamping types. The clamping assembly in the single-screw conveyor is fixedly connected to the screw. The screw can be rotated clockwise and counterclockwise to move the clamping assembly up and down or horizontally to clamp the cable, thereby realizing cable transportation. However, in the process of implementing the above technical solution, the inventors of this application found that the single-screw conveyor has the problem of insufficient clamping force. The single-screw conveyor with high clamping force occupies a relatively large area and is expensive. Therefore, a cable conveyor with high clamping force and small footprint is urgently needed to solve the above problem.
