The fly jib device is the important component part of aerial platform boom system; In order to improve the complete machine alerting ability of operation among a small circle; At present; Most of aerial platform fly jib system adopts parallel four linkages, is moved by oil cylinder direct drive jib, such device has that structure is not compact, scope of work is little, action not steadily and many shortcomings such as function singleness; Require than higher small-sized aerial platform for some structural compactness especially, traditional fly jib device often can not satisfy the designing requirement of overall dimensions of a car when retracted state.And when aloft work, the staff often needs the frequent thing of back and forth between operation point and ground, getting to operate, and work efficiency is very low.
Summary of the invention
(1) goal of the invention:
The purpose of patent of the present invention is the deficiency that overcomes above-mentioned prior art, the multi-functional fly jib device of small-sized aerial platform that a kind of compact conformation, flexible movements is provided and has the lift heavy function.
In order to arrive above-mentioned purpose, the multi-functional fly jib device of a kind of aerial platform provided by the invention comprises: firm banking, driving oil cylinder lower link, driving oil cylinder boxed rod, driving oil cylinder, fly jib head workplatform and fly jib agent structure.
Said firm banking is installed on aloft work vehicle main body jib head; Driving oil cylinder boxed rod two ends are connected in the A end of jib agent structure and driving oil cylinder respectively through bearing pin; Driving oil cylinder lower link two ends are connected in the A end of firm banking and driving oil cylinder respectively through bearing pin; The B end of driving oil cylinder is connected with the fly jib agent structure through bearing pin, and fly jib agent structure one end is connected in firm banking through bearing pin, and the other end is connected in workplatform through bearing pin.
Said fly jib device further comprises: the sprocket wheel chain transmission system.Said sprocket wheel chain transmission system comprises sprocket wheel I, tightening device, silent chain and sprocket wheel II; Said sprocket wheel II is connected with firm banking through flange; The sprocket wheel I is connected with workplatform through flange; Carry out transmission through silent chain between sprocket wheel I and the sprocket wheel II, tightening device is housed between the silent chain.
Said fly jib device further comprises: rise to give birth to suspension hook, elevator and leading sheave hoist; The said elevator that hoists is connected in fly jib agent structure afterbody through flange; Leading sheave is installed on workplatform through bearing pin; Steel rope is walked around the leading sheave that is fixed on the workplatform and is connected with a living suspension hook, and the elevator that hoists is controlled the folding and unfolding of steel rope through hydraulic-driven.
The multi-functional fly jib device of aerial platform of the present invention; Be installed on aerial platform principal arm head, realize that through install four linkages additional in the driving oil cylinder end fly jib moves in a big way, and adopt sprocket chain device to guarantee workplatform level all the time; Each action all uses mechanical device and sensor to carry out spacing; In order to guarantee safety, the chain sling of fly jib head can make things convenient for the staff to get the thing operation, increases work efficiency.
Description of drawings
