Description

Technical Field

[0002] Antenna is a device that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an open medium, or converts electromagnetic waves into guided waves. It is widely used in radio equipment to transmit or receive signals. There are various types of communication antennas, especially large and ultra-large antennas, which require stable support devices due to their size and weight. In order to ensure the signal coverage effect of communication antennas at different heights and angles, special lifting equipment is usually required to accurately adjust their position to meet various application requirements.

[0003] After searching, a Chinese invention patent with patent publication number CN101634861B discloses an antenna adjustment device, which is used in an antenna measurement system for measuring an antenna to be measured, and includes: a lifting frame having a movable device that can drive the antenna to move along the lifting frame, a fixing device installed on the movable device of the lifting frame, a transmitting antenna installed on the front of the fixing device, and a laser transmitter installed on the fixing device, wherein the laser transmitter and the transmitting antenna are located at different horizontal heights, and emits laser, and the height that the transmitting antenna needs to reach is determined by observing the position of the laser projection.

[0004] Based on the above patent, most of the antenna supporting devices currently on the market do not have the lifting function to appropriately adjust the antenna height according to usage requirements, which greatly limits the functionality of the antenna and its own receiving effect, and limits its functional upper limit. In addition, the few supporting devices with lifting function have extremely complex lifting structures and cumbersome operations, which can easily affect the comprehensive performance of the antenna itself, prolong the electromagnetic wave reception time, slow down the work progress, and thus lead to a narrow overall scope of application.

[0005] Based on this, the present invention proposes a communication antenna lifting device for an electric pole tower to solve the above problem. Summary of the invention

[0048] The stable support foot 2 combined with the high stable support structure of the load-bearing bracket 1 can ensure that the lifting device can achieve a stable support effect for the carried antenna in any environment. The target antenna equipment can be stably assembled and supported on the upper end of the antenna assembly bearing platform 24.

The lifting adjustment screw 5 passes through the threaded adaptation connection structure between the sleeve rod through hole 7 and the lifting adjustment screw hole 12, so that the first-level lifting bearing column 9 embedded in the first-level receiving groove 8 can receive the jacking force generated by the threaded adaptation rotation, so as to achieve the upward lifting antenna height adjustment effect.

While the groove 8 is lifting upward to adjust the height, the secondary lifting bearing column 14 is released from the secondary receiving groove 13 to adjust the lifting height upward. The adaptive sliding connection structure between the secondary lifting auxiliary slider 16 and the secondary lifting auxiliary directional groove 15 guarantees the structural stability of the secondary lifting bearing column 14 during the lifting process to the greatest extent, and correspondingly improves the overall lifting operation smoothness. The lifting drive motor 4 is controlled by the electric control box 6 to reverse its output shaft, so that the synchronous lowering adjustment operation of the secondary lifting bearing column 14 and the primary lifting bearing column 9 can be achieved, and the top position rotating bearing platform 18 can be controlled to rotate according to specific use requirements during long-term use, so as to achieve the effect of adjusting the orientation of the antenna carried on the upper end of the antenna assembly bearing platform 24. Similarly, controlling and starting the rotating adjustment motor 23 can drive the bearing connector 22 and the antenna assembly bearing platform 24 as a whole, so that the carried antenna can perform appropriate angle adjustment operations, effectively enriching the overall use functionality, and providing a relatively stable mechanism foundation for the lifting and bearing of large antennas and super-large antennas. It is relatively comprehensive in bearing stability and use functionality, and has extremely broad application prospects.
