[0014] Optionally, a limiting piece is fixed at the top of the guide rail, the limiting piece is made of rubber material, and the size of the limiting piece corresponds to the size of the support.

[0015] In recent years, the sharing economy is growing, and in the power and communication industry, the sharing of power towers is increasingly developed. With the advent of the 5G mobile communication era, the demand for communication towers has increased significantly, and the demand for land and site selection has become increasingly prominent. The power transmission and communication shared tower is to install communication equipment, including optical cables, communication base stations, antennas and other equipment, on the power tower. The power grid company has a large number of tower resources, and selecting appropriate power towers to build shared towers can significantly reduce the cost of 5G network construction in various places and improve the utilization rate of power line tower resources. On the other hand, it can also effectively solve the site selection difficulty of communication base stations, save land resources, and avoid repeated construction and investment.

[0016] The shared power tower is to install communication base stations, monitoring, photovoltaic or wind power equipment on the power tower under the premise of fully guaranteeing the safety of the power grid and the quality of communication. From the practical situation, the shared power tower can save land, time and cost, and is an innovative move to accelerate the construction of a resource-saving and environment-friendly society and realize the "advantage complementation, cooperation and win-win, and harmonious development" of state-owned assets.

[0017] The installation of the above-mentioned shared equipment on the power tower is mainly through the climbing of the tower by the operating personnel, welding the bracket on the tower, and installing the shared equipment on the welded bracket by the operating personnel in the high-altitude environment. The power tower sets the antenna at the top of the tower, and increases the cumbersome lifting equipment to meet the installation needs, increasing the engineering investment. Since the installation position of the shared equipment is relatively fixed, the operating personnel also climbs the tower to detect and maintain the shared equipment.

[0018] The installation of the above-mentioned shared equipment and the later inspection and maintenance all need the operating personnel to climb the power tower for construction. When the operating personnel climbs to the high place of the power tower and installs or maintains the shared equipment, the range of activity is narrow, which is not convenient for construction, so that the installation and maintenance of the shared equipment is time-consuming and laborious. In addition, the high-altitude working environment poses a great safety problem to the operating personnel.

[0019] The communication antenna installed on the power tower often needs regular maintenance and debugging and fault repair. In the past, when the communication department's professional personnel maintained the communication antenna, since the communication company's operation and maintenance personnel did not have the qualification of climbing the power tower with electricity, they often needed to report to the power supply company in advance to shut down the power transmission line involved to meet the requirements of safety regulations, which was complicated without procedures, and frequent power outages also reduced the reliability of power supply, restricting the promotion of power sharing towers. Moreover, the frequent climbing of the shared tower by the operating personnel is not safe, and there are high safety hazards and costs.

[0020] The positive and beneficial effects of the present application are:

[0021] 1) The antennas installed on the power sharing towers are controlled by guide rails and traction ropes, allowing for free raising and lowering. The support is raised and lowered using at least three pulleys, providing high stability and requiring minimal effort. Raising and lowering can also be done manually by pulling or rotating a control handle, making operation convenient and allowing for easy ascent and descent.

[0022] 2) Easy to operate and safe to use. The support frame is tilted downwards; a fixing block is installed at the rear of the support frame, and the fixing block is fixedly connected to one end of the traction rope; the shape and size of the fixing block correspond to and fit into the groove of the guide rail. This facilitates lifting and lowering and maintains the stability of the support frame, preventing swaying;

[0023] The protective enclosure is equipped with a mechanical or electronic lock to control its opening and closing. Under normal circumstances, the enclosure is locked closed by a mechanical or electronic lock, preventing outsiders from controlling the raising and lowering of the support structure via a traction rope, thus providing safety.

[0024] If an outsider damages the protective box and performs unauthorized operations, the alarm device will be triggered. The device uses a vibration or displacement sensor connected to the electronic lock signal. If there is no feedback from the electronic lock signal, the vibration or displacement sensor will directly trigger the alarm device, which will then send an alarm message to the mobile display terminal of the monitoring personnel at a distance via a wireless device, providing timely reminders and further improving security.

[0025] 3) It greatly improves work efficiency. The lifting and lowering are achieved by pulling and rotating the control handle. It is easy to operate and can be raised and lowered at will without having to climb the tower or use other tools or equipment.

[0026] 4) The traction rope is installed inside the tower via a steering pulley, ensuring the safe operation of the lifting device. This extends the service life of the traction rope and steering pulley, preventing swaying in strong winds and the impact of sand and gravel. It also ensures unobstructed or jammed operation during ascent and descent, guaranteeing normal operation.

[0027] 5) The towing device can be towed by a car, avoiding the problem of needing an external power supply for the electric towing device. It is suitable for some situations that require a large pulling force, such as when the weight of the communication antenna fixed on the bracket is too large. It saves the installer effort and allows them to have more energy to carry out installation and debugging work.

[0028] The present invention installs the communication antenna inside the lifting guide rail, and controls the raising and lowering of the antenna through a steering device and a traction rope, lowering the antenna to a maintenance position close to the ground. This solves the problem that communication antenna maintenance personnel of telecommunications companies are not qualified to climb power transmission towers while the transmission lines are energized, and that the power supply capacity is reduced when the transmission lines need to be shut down during antenna maintenance.
