Description
Technical Field
The invention relates to the technical field of heel block pulleys, in particular to a self-sealing heel block.
Background
The head-following pulley is a tool for transmitting an aluminum alloy ladder head and an insulating rope ladder to a live wire during equipotential operation. Live equipotential operating personnel must enter the strong electric field by climbing the insulated flexible ladder fixed by the heel block. Therefore, it is an indispensable tool for live working and is a 'gold key' for opening the live working process. In the operation of a power transmission line, the existing heel block does not have any locking protection.
When the heel pulley is used for lifting the insulating tool, the heel pulley is not firmly connected with the lead, so that the accident that the pulley and the insulating tool fall off from the lead occurs. Once the lead is bounced or the pulley is stressed unevenly, the lead slips off, and potential safety hazards that people are injured by falling objects from high altitude easily occur. Not only can the insulation tool be dirty, damp, unable to be used normally, even scrapped. But also threatens the personal safety of the operating personnel.
