Embodiment Construction

[0033] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] See Figure 1~4 , the present invention includes a mobile car body 1, a vertical telescopic unit, a horizontal telescopic unit and insulating claws 16, the vertical telescopic unit is fixed on the mobile car body 1, the horizontal telescopic unit is arranged at the top of the vertical telescopic unit, and the insulating claw 16 is arranged at the horizontal Telescoping unit ends. The mobile car body 1 plays the role of carrying and moving. The vertical telescopic unit can be lifted and lowered in the vertical direction, and the horizontal telescopic unit can be telescopic in the horizontal direction. The insulating claw 16 is used to carry the dry ice blast cleaning device 17, and the dry ice blast cleaning device 17 is used Clean the target with dry ice blasting. A small dry ice machine 18 is arranged on the horizontal...

Abstract

The invention discloses a sleeve-type lifting device for hot-line work. The sleeve-type lifting device comprises a mobile vehicle, a vertical telescopic unit, a horizontal telescopic unit and an insulation jaw. The mobile vehicle plays the effects of bearing and moving. The vertical telescopic unit can ascend and descend in the vertical direction, and the horizontal telescopic unit can stretch and retract in the horizontal direction. The insulation jaw is used for bearing a dry ice jet cleaning device. The dry ice jet cleaning device is used for performing dry ice jet cleaning on a cleaning target. The sleeve-type lifting device is simple in structure, convenient to move and operate, high in working efficiency and capable of completing cleaning tasks at a specific occasion efficiently. In addition, the sleeve-type lifting device uses electric power and compressed air as power sources at the same time, key components are made of insulation materials, and therefore working stability of the device can be not disturbed and influenced by high potentials, and insulation safety can be guaranteed.

Description

technical field [0001] The invention relates to a lifting device, in particular to a sleeve type lifting device for live working. Background technique [0002] Dry ice cleaning technology is to use dry ice blasting cleaning device to mix solid carbon dioxide particles with compressed air and spray them on the surface of the object to be cleaned for cleaning. After cleaning, the carbon dioxide particles sublimate and will not pollute the environment. At the same time, gaseous carbon dioxide itself is an insulating gas, and pollution flashover accidents will not occur during the cleaning process. Dry ice cleaning technology has been widely used in automobile manufacturing, aviation industry, nuclear power industry, food processing, petrochemical and other fields, and has obvious advantages compared with other electrified cleaning technologies. [0003] Due to long-term exposure to the natural environment, the surface of substation insulators will form a certain degree of poll...
