Problems solved by technology

[0028] Of course, in order to solve the above problems, the size of the insulating cantilever 50 can also be increased to improve durability, but in this case, the size of the subsequent intermediate cantilever 20 and the fixed cantilever 10 will increase, so the weight of the cantilever device may increase. , The problem of rising manufacturing costs

Embodiment Construction

[0064] The terms or words used in the specification and claims should not be interpreted in general or dictionary meanings, and the inventors can properly define the concepts of the terms in order to describe their invention in the best way. Based on this principle, the meaning and concept should be interpreted as conforming to the technical idea of ​​the present invention.

[0065] Refer to the following Figure 3 to Figure 10 A four-stage boom device (hereinafter referred to as "four-stage boom device") for a live working vehicle according to a preferred embodiment of the present invention will be described.

[0066] The four-stage cantilever device is composed of four cantilevers and constitutes a hybrid type, so that the insulating cantilever at the front end of the four cantilevers can be driven independently, and the secondary cantilever and the third-stage cantilever can be pulled in and out in conjunction with each other.

[0067] Since only the insulating cantilever ...

Abstract

The present invention relates to a four-stage boom device for a live-wire operations vehicle, and more particularly, to a four-stage cantilever device for a live working vehicle, which minimizes the telescopic length of the boom device to improve the utilization rate of a vehicle position space by independently leading out and leading in an insulating cantilever. The insulating cantilever is telescoped through the telescopic device which converts straight movement into rotary movement, so that the insulating range of the insulating cantilever is maximized, and the insulating performance is improved. The four-stage boom device for the live-wire operations vehicle comprises a first-stage boom, a second-stage boom, a third-stage boom, a linkage device, an insulating boom and an insulating boom telescopic device, and the insulating boom telescopic device comprises a second driving cylinder, a pair of rotating pulley wheels and a pair of transmission mechanisms. When the piston rod of the second driving cylinder moves straightly, the rotating pulley wheels rotate, and meanwhile, the transmission mechanism leads the insulating cantilever out of or into the third-stage cantilever.

Description

technical field [0001] The present invention relates to a four-stage cantilever device for a live working vehicle, and more specifically, to a method for maximizing the insulation performance of the insulating cantilever, minimizing the distance between the live working area and the vehicle through the independent telescopic drive of the insulating cantilever Four-stage cantilever for live work vehicles optimized for live work environments. Background technique [0002] Generally speaking, the aerial work vehicle has a multi-stage cantilever device, which is the equipment that can ride on the cantilever (ride) on the upper end of the vehicle to perform operations at high places. It is used for the installation of internal / external scaffolding, electrical and communication equipment. The erection and maintenance warranty, the internal construction of the factory roof, the inspection and maintenance of bridges, etc. [0003] like figure 1 As shown, the high-altitude operatio...
