Traction device facilitating cable tension adjustment for power construction

Abstract

The invention relates to the technical field of power construction, and discloses a traction device facilitating cable tension adjustment for power construction. The traction device comprises a platetrailer, a handle is fixedly connected to one side of the top end of the plate trailer, a winding and unwinding mechanism is mounted on the side, close to the handle, of the top end of the plate trailer, a tension adjusting mechanism is installed on the side, close to the winding and unwinding mechanism, of the top end of the plate trailer, and the winding and unwinding mechanism comprises a winding and unwinding door frame. According to the traction device, a cable in the winding and unwinding process is dragged through a first traction roller assembly, a second traction roller assembly and afixed traction roller assembly of the tension adjusting mechanism, so that the cable can keep certain tension, and winding and unwinding of the cable are facilitated; and meanwhile, the first traction roller assembly and the second traction roller assembly can move on the inner side of a first strip-shaped groove and the inner side of a second strip-shaped groove correspondingly, so that the tension of the cable can be adjusted, the cable is prevented from being pulled or bent and wound in the winding and unwinding process, and the safety of electric wires is improved.

Description

technical field [0001] The invention relates to the technical field of electric power construction, in particular to a traction device for electric power construction that is convenient for adjusting the tension of cables. Background technique [0002] In the process of electric power construction, it is often necessary to lay cables. Cable laying refers to the process of laying and installing cables along the surveyed route to form cable lines. According to the application occasion, it can be divided into overhead, underground (pipeline and direct) There are several laying methods such as buried), underwater, wall and tunnel. When the cable is laid, it is necessary to unwind the coiled cable. In the process of unwinding, the traction force should neither be too large nor too small. If it is too large, it will easily cause the cable to be strained, and if it is too small, it will easily cause the cable to bend. [0003] The Chinese patent discloses an easy-to-adjust cable r...

Problems solved by technology

[0003] The Chinese patent discloses an easy-to-adjust cable retractable device for electric power construction (authorized announcement number CN109081202B). This patented technology can increase the maximum winding volume of the winding roller by increasing the height of the winding roller, which is convenient for the device to be adjusted. Adjustment, increase the use range of the device, prevent the coil from falling off when the winding column increases its maximum winding amount, and effectively improve the stability of the device during use. When the device is winding, the cable is wound on the outer wall of the winding roller in an orderly manner , which effectively improves the winding efficiency of the device when it is used, but it is inconvenient to adjust the tension when the cable is retracted and unwound, which may cause the cable to be pulled or bent, and it is inconvenient to install and remove the cable reel
