Insulating flexible ladder head antiskid device

Abstract

The invention discloses an insulating flexible ladder head antiskid device comprising a base, wherein the base comprises a mounting plane, the mounting plane is provided with a rotating shaft vertical to the mounting plane, the rotating shaft is provided with a hook rod capable of axially rotating along a rotating shaft, the free end of the hook rod is provided with a hook used for being fixed with an L link plate of an extension insulator, the base is also provided with a structure which is dismountable and is used for being fixed with an insulating flexible ladder head, the device is convenient to carry and is arranged on an insulating flexible ladder. When the device is used, the device is fixedly connected with the L link plate of the extension insulator, thus ensuring that the insulating flexible ladder can not slide from a high end of a conducting wire to a low end of the conducting wire and meeting the condition of firm fixation; the device is convenient to use and is easy to mount, safety of an electric power worker in high altitude operation is improved, and pressure damage to the conducting wire can be avoided; and the device is simple and easy to manufacture, has extremely low maintenance cost and is applicable to popularization and application.

Description

technical field [0001] The invention relates to an installation tool for electric equipment, in particular to a device for anti-slipping of an insulating soft ladder head. . Background technique [0002] 110kv-220kv line live replacement lightning strike insulator is a routine project of live work in power supply enterprises, in which the insulation ladder is used to replace the tensile insulator string. The work site is less restricted, the soft ladder is light in weight, easy to fold and transport, and is widely used in equipotential work. Commonly used insulating soft ladders such as figure 1 shown. However, in the actual working process, there are certain deficiencies in the insulation ladder entering the equipotential. [0003] like figure 2 As shown in the figure, due to the common height difference in the transmission line and the design of the pulley hanging on the insulating ladder head, the pulley will slide from the high end to the low end on the wire due to ...

AI Technical Summary

Problems solved by technology

[0005] 2. In terms of safety, the soft ladder slides on the wire, which can easily squeeze the fingers and muscles of the workers, crush the clothes, and damage the seat belt; the derailment of the pulley may cause many safety accidents such as falling from high altitude;

[0006] 3. In terms of time, since the ladder head needs to slide upwards, it generally takes 10 minutes to return to the operating point if a 15-meter soft ladder is used for a 15° height difference line. If the height difference is larger and the soft ladder is longer, it will take longer;

[0007] 4. In addition, the operator needs to use a lot of force to move the ladder head to return to the operating point, which will cause excessive physical exertion of the operator and affect the operator's precise and safe operation
