Insulated Boom Crane

Abstract

The invention discloses an insulating arm crane. It includes the front of the car, wheels and the car body composed of the frame, and also includes three mutually nested and flexible insulating arms. The front end of the insulating arm is provided with an insulating hook; the two sides of the frame are provided with telescopic hydraulic pressure Outriggers, a turntable connected by a slewing mechanism is arranged on the platform of the frame, and an insulating arm support is hinged on the turntable, and the insulating arm is installed on the turntable through the insulating arm support; the insulating arm can be driven by an oil cylinder arranged on the turntable. Swing between vertical direction and horizontal direction; there is also an insulated working bucket that can be operated by the staff on the frame. Its advantages are: it can ensure the pressure resistance of the whole vehicle reaches 220kv; the arm body has high strength and high bending strength; The insulated working bucket that can be quickly loaded and unloaded has a large carrying capacity and working height, which meets the requirements of high-altitude operations.

Description

technical field [0001] The invention relates to a lifting device for electric power operation, in particular to an insulating arm crane. Background technique [0002] At present, with the development of my country's economic construction, the requirements for power supply are getting higher and higher, and it is required to use live working methods to deal with power maintenance problems and reduce economic losses caused by power outages. [0003] Most of the existing live working vehicles are insulated high-altitude operating vehicles, and the load capacity of the vehicles is less than 0.5 tons. It is difficult to replace and install heavier electrical components. Especially when working in a substation, even if the maintenance equipment is powered off, there is still high voltage in the surrounding adjacent equipment, and the degree of operation risk is relatively large; at the same time, because the equipment is installed on a fixed bracket, the fixed bracket has a standa...

Problems solved by technology

[0003] Most of the existing live working vehicles are insulated high-altitude operating vehicles, and the load capacity of the vehicles is less than 0.5 tons. It is difficult to replace and install heavier electrical components.

Especially when working in a substation, even if the maintenance equipment is powered off, there is still high voltage in the surrounding adjacent equipment, and the degree of operation risk is relatively large; at the same time, because the equipment is installed on a fixed bracket, the fixed bracket has a standard height, and the safety distance of the equipment is limited. Strict requirements, the vehicle must pass through the lower part, which requires the vehicle to be small in size, especially the height is strictly limited. Ordinary cranes cannot work without power failure in adjacent intervals; existing insulated aerial work vehicles cannot meet the requirements. site requirements
