Description

Technical Field

[0001] The present invention relates to the field of communication equipment, and more particularly to a signal tower. Background Art

[0002] The main function of a signal tower is to serve as a transmitter of wireless signals, support signal transmission, and provide support for signal transmission antennas. In modern society, a large amount of data is transmitted every moment. Once a signal tower fails, it will not only affect people's normal lives, but may also cause a large amount of property losses. Therefore, once a signal tower fails, it usually needs to be repaired quickly. Traditional maintenance is usually done by maintenance workers using climbing foot buckles and safety ropes.

[0003] The process of maintenance workers climbing to the top of the signal tower using climbing foot clips and safety ropes is less safe, and workers cannot carry too many maintenance tools. The entire maintenance process is long and inefficient.

[0004] Therefore, how to provide a signal tower that can overcome the above problems is an issue that those skilled in the art need to solve urgently. Summary of the invention

[0005] In view of this, the present invention provides a signal tower.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The present invention discloses a signal tower. The present invention designs a lifting mechanism. When the hoist 03 in the lifting mechanism is performing a rope-collecting action, the sleeve 1 05 in the tower body 01 can move vertically upward. When the hoist 03 is performing a rope-releasing action, the sleeve 1 05 can move vertically downward. The movement of the sleeve 1 05 drives the movement of the sleeve 2 08 in the bearing platform, thereby realizing the lifting and lowering of the bearing platform. Due to the design of the long hole 010 and the limit block 080, the sleeve 1 05 or the sleeve 2 08 will not rotate relative to the tower body 01, thereby ensuring the stability of the lifting and lowering process of the bearing platform. The bearing platform also includes an annular platform and an annular guardrail. Workers can stand on the annular platform to inspect and repair the communication equipment 02, and the workers have ample space for activities. The annular guardrail can protect the workers from falling.

[0026] The support plates 09 in the annular platform can be folded upward when not in use, thereby reducing space occupation. When the support plates 09 are arranged horizontally, the arc rods 11 can be pulled out, and the arc rods 11 can fill the gaps between adjacent support plates 09 to prevent people or objects from falling from the gaps.

[0027] The baffle 12 in the annular guardrail can be bent relative to the support plate 09. While ensuring that the baffle 12 and the wire rope 13 play a protective role, the baffle 12 and the wire rope 13 are easy to store, and the top rod 14 can ensure that the baffle 12 maintains a vertical arrangement state.
