Description

Technical Field

[0001] The utility model mainly relates to the field of power transmission iron towers, and in particular to an iron tower anti-falling device used in line engineering. Background Art

[0002] The transmission tower is the supporting point of the overhead line. If one circuit is erected on the transmission tower, it is a single-circuit transmission tower, and if two circuits are erected on the transmission tower, it is a double-circuit transmission tower. A single circuit refers to a circuit in which one load has one power supply; a double circuit refers to a circuit in which one load has two power supplies. Generally, enterprises with high requirements for power supply reliability or important regional substations use double-circuit power supply, which can protect one of the power supplies from power outages for some reason, while the other power supply can continue to supply power. However, small and medium-sized users who do not have high requirements for power supply reliability often use a single power supply;

[0003] When power is transmitted for a long time on a transmission tower, the circuit is easily damaged, and workers need to climb the transmission tower manually to transmit the circuit. When workers climb the transmission tower manually, they need to connect to the anti-fall device through a safety rope to protect their safety.

[0004] During the operation of the specific embodiment, the utility model found the following defects:

[0005] The self-locking device at one end of the safety rope is connected to the outer wall of the guide rail. When the worker climbs, the self-locking device slides on the outer wall of the guide rail. When the self-locking device needs to be installed on another guide rail for horizontal climbing, the self-locking device at one end of the safety rope needs to be detached from the guide rail. The supporting strength of a single safety rope is reduced, and the safety of the worker cannot be ensured.

[0006] It should be noted that the above contents belong to the technical cognition scope of the utility model applicant. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

[0026] The unstable outdoor temperature can easily cause the guide rail to expand and contract. When the second guide rail expands and contracts, the second auxiliary groove at the bottom of the guide rail is driven by the second guide rail to slide inside the shock-absorbing block and the second auxiliary groove moves on the outer wall of the second U-shaped threaded column. In the process of fixing the second guide rail, the second guide rail can move in a certain direction to avoid bending of the guide rail caused by thermal expansion and contraction. Finally, the shock-absorbing block supported by rubber material can insulate and dampen the guide rail. BRIEF DESCRIPTION OF THE DRAWINGS
