A lifting mechanism for a communication cable support rod

Abstract

The present invention discloses a rise mechanism of a communication cable bracing piece. The mechanism comprises a support column, a fixed mechanism is fixedly installed at the bottom portion of the support column, a height regulation mechanism is installed at the internal portion of the support column, and a fine tuning mechanism is installed at the upper end of the height regulation mechanism; and a drive mechanism is installed at the upper portion of the support column, the drive mechanism is in transmission connection with the height regulation mechanism, and a dead lock mechanism is installed at the bottom portion of the drive mechanism. A drive gear drives a transmission gear to rotate, and the transmission gear is in engagement transmission with a height regulation rack so that a height regulation rod is driven to lift and the height regulation of the device is achieved, and a connection rod is driven to achieve threaded connection with an external rod so as to perform height regulation at the ground; a fine tuning spring is employed to allow a fine tuning rod to float up and down and can perform fine tuning with the change of the relaxation degree change of a cable so as toavoid damaging of the cable; and a lock dead spring is employed to drive a dead lock pin to rise through a lifting plate so as to achieve dead lock of the drive gear, avoid automatic declination of the height of the device and improve the safety performance.

Description

technical field [0001] The invention relates to the technical field of communication auxiliary devices, in particular to a lifting mechanism for a communication cable support rod. Background technique [0002] The communication cable is the main part of the communication facility. In order to ensure the safety of the cable, according to the requirements of the operation regulations of the power communication line, the minimum arc distance of the cable should be 4.5 meters. During maintenance, try to ensure that the distance between the cable and the ground reaches 5 meters. With the development of the city, roads and other settings are developing to the suburban field. Due to the height of the foundation, the height of the cable is already lower than the safe height, and the cable is easily scratched and pulled by taller vehicles, posing a safety hazard. It is time-consuming and labor-intensive to replace the original support rod, so it is necessary to add a lifting mechani...

Problems solved by technology

[0004] The purpose of the present invention is to provide a lifting mechanism for the communication cable support bar in order to solve the above problems, so as to solve the current lifting mechanism in the prior art, the height cannot be adjusted at any time on the ground, and the adjustment efficiency is low; As the temperature changes, the slack of the cable will change. The current lifting mechanism does not have a fine-tuning mechanism, which is easy to cause damage to the cable; at the same time, there is no locking mechanism, the device has a risk of falling, and there are technical problems such as potential safety hazards.
