Description
Technical Field
The invention relates to the field of communication towers, in particular to a top-supported lifting type communication tower.
Background
Communication tower is more common in life, and its main objective is the transmission mobile signal to realize people's daily trip and play, in order to improve mobile signal's transmission range, the communication tower can all make higher, but the superhigh communication tower also has brought certain puzzlement in installation and transportation, need just can accomplish the installation of communication tower with the help of large-scale loop wheel machine.
After the communication tower is installed, communication staff needs to maintain antenna equipment and the like on the communication tower regularly, and the current operation basically is that maintenance staff climbs to the highest position of the communication tower for operation, so that the risk is high. So that the lifting type communication tower appears in the market and is mainly divided into a screw rod sliding block principle, a hydraulic lifting principle and a rope lifting principle; principle of screw rod slide block: for example, in a liftable communication base station with application number 201710153615.1, although the lifting mode can lift a plurality of sections of tower bodies to the tower body at the bottommost part, the lifting mode is realized by the principle of a screw rod sliding block, and the processing requirement of a screw rod is relatively high because the height of the tower body is relatively high, the strength of the screw rod is insufficient due to the thin outer diameter of the screw rod, and the cost is relatively high due to the thick outer diameter of the screw rod. Hydraulic jacking principle: for example, the hydraulic integrated base station with the application number of 201010104711.5 realizes lifting of the tower body through a hydraulic lifting principle, and a hydraulic system is high in cost and complex in maintenance. Rope pendant principle: for example, the application number is 201010109605.6, the lifting of the multi-section tower body is realized through the rope pendant, the rope is installed in the tower body to carry out linkage lifting, the fixed pulley is difficult to install, and meanwhile, the rope needs to lift the tower body by a thicker rope, so that the pulley matched with the rope needs to be large enough, and the installation space is met by the tower body in a phase-changing manner. The lifting modes of the three communication towers can realize lifting, but have the defect that the lifting mode cannot be avoided.
