Background
In the prior art, with the development of economic society, the voltage grade of a line is continuously increased, and higher requirements are put forward on the operation and maintenance level of a power transmission line. Especially, the power transmission lines in remote mountain areas have complex landforms and are difficult to operate and maintain. The personnel allocation of the transmission staff is always insufficient, so that the fatigue strength of the transmission staff is increased when the transmission staff climb the tower, and the risk of falling from high altitude is increased.
The climbing of the transmission line tower is the basic capability of transmission staff, and the transmission staff need to climb up and down the tower, such as daily tower climbing inspection, tower climbing inspection required after a fault, tower climbing inspection during maintenance and the like.
Because no convenient tower climbing protection measure exists, great potential safety hazard is brought to transmission staff when the transmission staff climb the tower.
In order to solve the problem that no safety protection is provided for climbing the power transmission line tower, the problem is urgently needed to be solved,
SUMMERY OF THE UTILITY MODEL
The utility model aims at the aforesaid not enough and provide a protection measure is prevented weighing down when transmission of electricity specialty climbing shaft tower, realize preventing the emergence of high altitude phenomenon of falling.
The technical solution of the utility model is that: the protection device is characterized by comprising a lantern ring, two unidirectional sealing doors which can only move upwards are connected in the middle of the lantern ring, an anti-slip pad is embedded at the upper end of the lantern ring, the lower portion of the anti-slip pad is opened, a left gear mechanism and a right gear mechanism are arranged inside the lantern ring, the left gear mechanism and the right gear mechanism are respectively connected with a left push rod and a right push rod which push the lower portion of the anti-slip pad to tighten inwards, the left gear mechanism and the right gear mechanism are respectively connected with a left steel wire rope and a right steel wire rope, the left steel wire rope and the right steel wire rope are folded and reinforced and connected onto an insulating endless rope from the outlet of the lower end of the lantern ring, the insulating endless rope is connected with.
The utility model has the advantages that: adopt lantern ring formula anti-falling device, can be convenient embolia the lantern ring on the foot nail of shaft tower, can relax again take out the lantern ring from the foot nail, convenient operation, if the phenomenon of falling takes place, the one-way slipmat of sealing door, upper end and the inside gear mechanism of lantern ring middle-end can be more effectively with the foot nail interlock, prevent that the accident of falling from taking place.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Drawings
