Multifunctional aloft-work mechanical arm

Abstract

The invention discloses a multifunctional aloft-work mechanical arm. A macro-working device with three degrees of freedom is arranged on a frame of a carrying motor car. The multifunctional aloft-work mechanical arm is characterized in that: a micro-working device with multiple degrees of freedom is arranged at the top end of the micro-working device, and the top end of the micro-working device with multiple degrees of freedom is provided with a tool connecting frame used for selecting and carrying various tool units. The macro-working device is a basic mechanical arm which is provided with arotary table with a revolving support, a telescopic arm, a variable amplitude oil cylinder and a telescopic oil cylinder and is structurally characterized in that the rotary table is provided with the revolving support; a hinged shaft for the telescopic arm is articulated with the revolving supported rotary table with the revolving support; a variable amplitude oil cylinder block is articulated with the rotary table with the revolving support through a hinged shaft; and the end part of the variable amplitude oil cylinder is articulated with a basic arm of the telescopic arm through a hinged shaft, the bottom of the telescopic oil cylinder is fixed on the basic arm, and the end part of the telescopic oil cylinder is articulated with a secondary arm of the telescopic arm through a hinged shaft. The invention has the advantages of high automation degree, good safety, convenience, rapidness, high working efficiency and wide application range.

Description

technical field [0001] The invention relates to a construction machine, in particular to a multifunctional high-altitude operation mechanical arm for high-altitude operations; it is a device for high-altitude operations in the fields of electric power, gardens, municipal administration and the like. It is most suitable for the installation, maintenance and testing of high-altitude power facilities and municipal facilities, as well as the pruning, spraying, cleaning and testing of tall trees in gardens. technical background [0002] At present, most of the aerial work is to send personnel and tools to the aerial work place for construction through a liftable and movable working platform. Due to the limitations of the working platform's own load and personnel strength, high-altitude workers cannot carry heavy tools and equipment for construction. In many cases, they can only work manually, resulting in low construction efficiency and high labor intensity. However, due to the ...

AI Technical Summary

Problems solved by technology

Due to the limitations of the working platform's own load and personnel strength, high-altitude workers cannot carry heavy tools and equipment for construction. In many cases, they can only work manually, resulting in low construction efficiency and high labor intensity.

However, due to the influence of the external dimensions of the working platform, this kind of aerial work method cannot enter the narrow space for operation, which limits the applicable field of aerial work platforms.

In addition, manned high-altitude operations have very high safety requirements. However, although the current system has multiple protections, it cannot completely solve the problem of high-risk personnel working at high altitudes, and cannot completely avoid the safety of possible car crashes.
