Communication cable supporting equipment of construction lift with ascent auto-detection means of cage

摘要

The present invention relates to a communication cable winding device for a construction lift in which a cage automatic lifting means is installed, and is freely rotated on a support bracket fixed to a lower portion of a cage, and a repeater installed on the ground and a receiver installed inside the cage. A one-way drive motor fixed to the lower part of the cage so as to have a cord reel wound with a communication cable to be connected, a drive shaft configured to be interlocked with the shaft at one end of the shaft, and a rotation gear fixed to the shaft between the cord reel and the drive motor. Lifting automatic sensing means of the cage consisting of a sensing sensor fixedly installed on one side of the support bracket to detect the rotational speed of the gear, and a through hole through which the communication cable connected to the repeater is wound around the support bracket and wound on the cord reel. Guide brackets and fixed to one side inside the through hole of the guide brackets And a switch configured to operate according to the tension of the communication cable to control the power supply to the drive motor, wherein the winding device is integrally formed with a pair of supports to be opened toward the cage at the end thereof and faces each support end. The holding rubber is fixed, and the holder is fixed several times to maintain the same distance to the top and bottom of the mast, and one side is fixed to the lower portion of the guide bracket, the other side is bent downward toward the mast is installed and passed up and down into the holding rubber In addition, the present invention is characterized in that it further comprises a guide pipe configured to penetrate the communication cable therein, according to the present invention by installing the communication cable in the installation device separately from the power supply line to reduce the fatigue of the operator during the expansion work of the mast, preventing disconnection It does not need to extend communication cable until dismantling. It can prevent a number of effects such as preventing malfunctions when the lift and cage are lifted by the power supply line, blocking foreign substances into the automatic sensing means, providing convenience for work, and preventing the occurrence of safety accidents.
