A self-adjusting cable tensioning device

Abstract

The invention belongs to the field of distribution network supporting equipment, in particular to a self-adjusting cable tensioning device. A take-up and take-up distance of that connected fixed electric wire can be set by setting the length of the take-up and take-up cable or the take-up and take-up cable, so that that tension capacity is adjusted, at the same time, the self-adjusting ability isrealized by using the spring to control the rotary drum and using the weight to reset the reset cable, that is, when the tension on the take-up and take-up cable reaches a certain threshold value, thereel is pulled so that the drum, the pawl disengages from the inner ratchet wheel, The drum can rotate freely, so that the take-up and take-up cables are loosened, A tensioning force of that protectmechanism is reduced, After the instantaneous stress disappears, the pawl returns to the original position, and the drum and pawl are connected with the inner ratchet wheel. The gravity of the heavy object causes the return cable to pull and the inner ratchet wheel or the rotary box to rotate so as to recover the cable and keep the original tensioning degree on the electric wire.

Description

technical field [0001] The invention belongs to the field of distribution network supporting equipment, and in particular relates to a self-adjusting cable tensioning device. Background technique [0002] During the installation of cables and various structures of the redistribution network, it is often necessary to use various pretensioning or tensioning and maintaining devices to enable the corresponding structures to achieve specific functions or effects. However, the existing tensioning mechanisms generally only use elastic structures such as springs to achieve limited tension control, and cannot perform self-regulation according to actual needs. However, in actual situations, more complex control methods are often required to ensure the integrity of the functional structure of the equipment or mechanism.

Problems solved by technology

However, the existing tensioning mechanisms generally only use elastic structures such as springs to achieve limited tension control, and cannot self-adjust according to actual needs.

However, in actual situations, more complex control methods are often required to ensure the integrity of the functional structure of the equipment or mechanism. There is a solution through fixed connection. Once local strong wind or sudden force is encountered, because the two ends of the cable are fixed, it is easy to cause accidents such as breaking or the collapse of the pole.
