Abstract

The invention discloses an adjustable insulating flat ladder hook for equipotential operation, and belongs to the field of electric operation equipment. The problems that in the prior art, the adjustable insulating flat ladder hook for equipotential operation is not available, wherein the adjustable insulating flat ladder hook is simple in structure, convenient, reliable and convenient to mount, the position of the insulating flat ladder hook can be adjusted during use, and the operation position can be conveniently adjusted by workers are solved. The adjustable insulating flat ladder hook mainly comprises a rack, and a fixing sleeve is arranged at the tail end of the rack. Two main U type wheels are arranged on the rack, the two main U type wheels are connected through a chain, a rotary gear is arranged on the chain, and the rotary gear is provided with a rotary handle. A through hole and a clamping block I are arranged on the rack, a vertical column is arranged in the through hole, an auxiliary U type wheel is arranged below the vertical column, the auxiliary U type wheel is connected with the vertical column through a U type wheel fixing part, and a clamping block II is furtherarranged on the vertical column. Stop blocks are arranged at the upper end of the vertical column, and a pressure spring is arranged between the stop blocks. When the adjustable insulating flat ladderhook enters an electric field with an insulating flat ladder method, the adjustable insulating flat ladder hook is mounted on a ladder head of an insulating flat ladder.

Description

technical field [0001] The invention relates to an electric power operation equipment, in particular to an adjustable insulating flat ladder hook for equipotential operation. Background technique [0002] The traditional method of installing an insulated flat ladder is to hook the live wire through the terminal hook provided at the front end of the ladder body. The ladder hook can enable the staff to easily hook the wire. When a longer ladder frame is used, a middle lifting rope is usually added in the middle to make the ladder body more stable, the ladder head is controlled reliably, and the tail of the ladder is tied to the cross angle iron of the corresponding iron tower with ropes, so that the horizontal ladder points to the live equipment . Most of the existing insulating flat ladder hooks are non-adjustable and installed in a fixed manner, which is inconvenient for operators to operate specifically and is very inconvenient to use. [0003] Just lacking a kind of simp...
