Abstract
The invention relates to a jib system for an overhead operating platform. The jib system comprises a basic jib, a first connecting frame, a first derricking cylinder, a first connecting rod, a first hoisting jib, a second connecting frame, a second connecting rod, a second hoisting jib, a second derricking cylinder, a connecting rod and a rotary table, wherein the first connecting frame is connected with the basic jib by a connecting shaft; the first derricking cylinder is connected with the first connecting frame and the basic jib by connecting shafts; the first connecting rod and the first hoisting jib are connected with the second connecting frame by connecting shafts; the second connecting frame is connected with the first connecting rod, the first hoisting jib, the second connecting rod and the second hoisting jib by connecting shafts; the second connecting rod and the second hoisting jib are connected with the second connecting frame and the rotary table by connecting shafts; the second derricking cylinder is connected with the rotary table and the second hoisting jib by connecting shafts; the connecting rod is connected with the second hoisting jib and the first hoisting jib by connecting shafts; and the rotary table is used for fixing the jib system. The jib system of the invention is crank-type; and the lifting movement of the jib is realized by adopting a connecting rod linkage principle. And the lifting purpose can be achieved by adopting two derricking cylinders.
Description
Technical field
The present invention relates to a kind of boom system, be specifically related to a kind of high-altitude operation platform boom system.
Background technology
High-altitude operation platform (Aerial work platform) is the product of serving in mobility aloft work such as every profession and trade aloft work, equipment installation, maintenance.The high-altitude operation platform Related product mainly contains: six big classes such as scissor-type high-altitude operation platform, in-vehicle high-altitude operation platform, crank arm type high-altitude operation platform.At present, the boom system of aerial lift device has straight arm type and folding-jib, but cost is very high, the boom system volume of straight arm type and folding-jib is very big, complex structure, and maintenance difficulty is big, profile is not attractive in appearance, and the practicality of equipment, economy, safety remain further to be improved.
Summary of the invention
At the prior art above shortcomings, it is little that the object of the invention aims to provide a kind of volume, simple in structure, easy to maintenance, good looking appearance, practical, economic, safe high-altitude operation platform boom system.
The technical scheme that the present invention takes is that a kind of high-altitude operation platform boom system comprises basic arm, it is characterized in that also comprising by adapter shaft and basic arm bonded assembly first link span; By adapter shaft and first link span, basic arm bonded assembly first amplitude oil cylinder; By adapter shaft and the second link span bonded assembly first connecting rod and first lift arm; By adapter shaft and first connecting rod, first lift arm, second connecting rod, the second lift arm bonded assembly, second link span; By adapter shaft and second link span and the turntable bonded assembly second connecting rod and second lift arm; By adapter shaft and turntable, the second lift arm bonded assembly, second amplitude oil cylinder; By adapter shaft and second lift arm, the first lift arm bonded assembly pipe link; And the turntable of fixed arm frame system.
According to the further setting to technique scheme, second connecting rod, second lift arm and first connecting rod, first lift arm constitute two groups of parallelogram respectively; Pipe link connects first lift arm and second lift arm, and two groups of parallelogram form interlock.
The invention has the advantages that boom system is the crank arm type boom system, adopt connecting rod interlock principle to realize the lifting action of jib, connecting rod and arm adopt high strength steel to make, safety factor is higher, only adopts two amplitude oil cylinder just can reach the lifting purpose, and practical value is higher, hydraulic fittings still less, reduced the leak point, keeped in repair easylier, economy is better, the implementation method uniqueness is convenient to promote.
