Insulation apparatus for a riding basket of a high-place working vehicle

摘要

The present invention relates to an insulation device for a boarding basket of a high place operation car capable of allowing a boarding basket to be insulated from a boom even through the boarding basket is in contact with high tension wires because of the carelessness of the workers who board on the boarding basket in operation since a space between the boarding basket and the boom is insulated; thereby preventing the electric shock accidents of workers and the peripheral people including a car body of a high place operation car and a driver A plurality of vertical assembly holes having a boring groove in which a connection bolt penetrates are formed in the outer portion of a load cell. Through-holes through which the connection bolt penetrates are formed at positions corresponding to the vertical assembly holes in the circumference of a lower fixed plate. Multiple tap holes to which the connection bolt is coupled are formed at positions corresponding to the through-holes in the outer circumference of a worm wheel. An insulation plate is arranged between the top surface of the worm wheel and the bottom surface of the lower fixed plate. Insulation bushings for insulating between the connection bolt and the vertical assembly hole are arranged inside the vertical assembly holes in which the boring groove is formed. Insulation rings for insulating between the connection bolt and the vertical assembly hole are formed on the circumference of the through-holes of the lower fixed plate.
