Description
Technical Field
The invention relates to a backup protection device for climbing a power transmission line tower without an anti-falling protection device, and belongs to the technical field of power transmission maintenance tools.
Background
When transmission line construction, maintenance operation, because transmission line shaft tower mounting structure can't use the safety belt to the operation personnel climbing overall process and protect, when climbing this type of shaft tower, there is personnel potential safety hazard that falls from the high altitude. Violate "national grid company electric safety work rules (line section)" 6.2.3: when an operator climbs a tower, shifts on the tower and operates on the tower, the hand-held components are firm, the safety protection is not lost, and the safety belt is prevented from being separated from the top of the tower or being damaged by sharp objects. In order to ensure that safety protection is not lost, the personal safety of operators on and off the tower is ensured, and 7.10 electric power safety work regulations (line part) of national grid companies are met at the same time: the anti-falling protection device is required to be arranged on the steel pipe tower, the tower with the height of more than 30m and the line tower with the height of 220kV and above, and can prevent operators from going up and down the tower and the horizontal movement on the tower, the anti-falling rail is required to be arranged on the power transmission line tower, and the operators can go up and down the tower by using the anti-falling device as a backup protection measure. However, the anti-falling track has the reasons of high installation cost, potential safety hazards and the like, and most of the power transmission line towers are not installed, so that operators climb the towers without safety belts and backup protection measures, and rule regulations are violated. At present, a backup protection device for climbing a power transmission line tower which is not provided with an anti-falling protection device is not available in China, and the method comprises the following steps: the operating personnel connects two transmission line with wire protection lifting hooks on the safety belt, uses insulating rope to connect between safety belt and the wire protection lifting hook. When ascending, the first wire protection lifting hook is installed on the angle iron, personnel ascend for a certain distance, and then the second wire protection lifting hook is installed. Because the special structure of the wire lifting hook can be remotely operated to separate from a hook object, a person removes the first wire protection lifting hook under the protection of the second wire protection lifting hook, and sequentially circulates until climbing to an operation position, and the same operation is adopted when the person gets off the tower, so that the wire protection lifting hook plays a role in protecting a safety belt in the whole process. Although the method ensures that the operating personnel have safety protection measures in the process of climbing the tower, when the wire protection lifting hook is installed and climbs upwards, the personnel are above the installation position of the wire protection lifting hook, namely the safety belt is used in a low hanging height mode, and breaks 7.9 pieces of electric power safety work regulations (line part) of national power grid companies: the safety belt hook or rope should be hung on a firm component or a steel wire rope specially used for hanging the safety belt, and a high hanging and resisting mode should be adopted, so that the violation phenomenon also exists in the method.
In order to change the occurrence of similar situations, a backup protection device for the transmission line tower is urgently needed to appear, wherein the backup protection device is used for climbing the transmission line tower without being provided with the anti-falling protection device, so that the safety of operating personnel climbing the transmission line tower is improved, the safety protection of the operating personnel is not lost, and the personal safety is ensured.
