Problems solved by technology

[0003] When the cable pretensioning device in the prior art is used, the pulling force on the cable is small, resulting in a poor pretensioning effect on the cable, and the cable does not have a self-locking effect after pretensioning, resulting in The cable is unstable after pre-tensioning, so there is an urgent need for a cable pre-tensioning device for electric power construction to solve the above problems

Abstract

The invention provides a cable pre-tensioning device for power construction. The cable pre-tensioning device is novel in structural design. The cable pre-tensioning device comprises a shell, the inner wall of one side of the shell is connected with an upper connecting shaft through a bearing, the exterior of the upper connecting shaft is connected with a worm gear and a driving belt wheel through flat keys, the inner walls of the two sides of the shell are connected with worms through bearings, the worms are meshed with the worm gear, and the inner wall of one side of the shell is connected with a lower connecting shaft through a bearing; the outer portion of the lower connecting shaft is connected with a winding wheel and a driven belt wheel through flat keys, a transmission belt is in transmission connection between the driven belt wheel and the driving belt wheel, a connecting rope is wound in the winding wheel, a lock sleeve is arranged at the bottom end of the connecting rope, and the outer wall of one side of the shell is connected with a motor through bolts. According to the design, the driving belt wheel with the small diameter is used for driving the driven belt wheel with the large diameter to rotate through the transmission belt, so that the winding wheel can obtain large pulling force when winding the connecting rope, the cable is pre-tightened, the pulling force is larger, and the pre-tightening effect of the cable is better.

Description

technical field [0001] The invention specifically relates to the technical field of cable construction devices, in particular to a cable pretensioning device for electric power construction. Background technique [0002] Cable is a general term for items such as optical cables and cables. There are many uses of cables, mainly used for multiple functions such as control installation, connection equipment, power transmission, etc. It is a common and indispensable thing in daily life. In the construction of cables, it needs to be fixed with ground fixed points The pre-tensioning device tensions the cable, so that the cable is in a taut state after installation. [0003] When the cable pretensioning device in the prior art is used, the pulling force on the cable is small, resulting in a poor pretensioning effect on the cable, and the cable does not have a self-locking effect after pretensioning, resulting in The cable is unstable after being pre-tensioned, so there is an urgen...
