Description
Technical field
The telescopic lifting type of drive that the present invention relates to a kind of attached frame type combined shear-fork streatching-lifting mechanism is improved.Especially the pull and draw drive-type additive frame combined scissor fork expanding and lifting mechanism of being done to drive by the drag-line tractive is stretched.
Background technology
In the prior art, scissors mechanism the most common the most habitual be to be done to drive by hydraulic actuating cylinder to realize that telescopic lifting changes.Though the powerful flexible movements of this driving power, but it must pressurize from oil pump, pipeline is carried, high pressure control is done work to oil cylinder, the various parts precision of system complex mechanism, especially pressure duct and control system will be in case faults such as generation leakage will seriously jeopardize safety, so it ensures that setting again must be especially thorough complete; Oil hydraulic cylinder also is difficult to the state that remains unchanged for a long time under heavy load simultaneously.There are the difficult cost height of the numerous manufacturing of volume macrostructure, fault to safeguard obvious deficiencies such as the many safe differential of tired limitation frequently in a word." attached frame type combined shear-fork streatching-lifting mechanism " (Chinese patent application 200610049620.X) is the extremely wide new invention of a kind of superior performance applicable surface, so its telescopic lifting drives the deficiency that more should avoid above-mentioned and regrets.
Summary of the invention
The objective of the invention is to provide a kind of pull and draw drive-type additive frame combined scissor fork expanding and lifting mechanism mechanism, utilize drag-line and pulley combination to transmit strength, drive the scissors rod variable angle with tractive and control drag-line and realize telescopic lifting.
The object of the present invention is achieved like this: the pull and draw drive-type additive frame combined scissor fork expanding and lifting mechanism disposes pulley, drag-line and tractive dynamic assembly by additive frame combined scissor fork flex lifting gearing and forms.Described additive frame combined scissor fork flex lifting gearing by attached frame and cut the fork stacked row constitute; Wheels arrangements is in the crosslinked node of scissors rod, drag-line links up serial between each pulley, the tractive dynamic assembly drives and controls the tractive of drag-line, transmits the change of tractive strength or limits scissors rod variable angle state through pulley, and tractive drives the telescopic lifting variation of additive frame combined scissor fork flex lifting gearing.In the pull and draw drive-type additive frame combined scissor fork expanding and lifting mechanism, each is cut the stacked row of fork and can dispose the combination of one or several pulley and drag-line and make tractive and drive, and can make tractive and drives by partly or entirely cutting the stacked row configuration pulley of fork and drag-line combination.The tractive dynamic assembly is made up of power, connection and speed change, control etc., can be installed on any part position such as upper and lower, inside and outside of mechanism, by pulley turnover companys of passing through drag-line, bears and control the tractive driving of drag-line.The responsible mechanism of the contraction down maneuver own wt of pull and draw drive-type additive frame combined scissor fork expanding and lifting mechanism realizes, also can establish special pulley drag-line tractive or other mechanism form in addition and realize acceleration and accurate control of shrinking or descending.
The pull and draw drive-type additive frame combined scissor fork expanding and lifting mechanism has the powerful stable running highly effective and safe of load, the widely applicable appropriateness of novel and reasonable structure, telescopic lifting and steadily makes advantages such as safeguarding Lian Yi, machinery and the parts of various telescopic liftings can be simplified and improve to work and the purposes of the alternative and multiple oil hydraulic cylinder of displacement; Can serve construction work such as building decoration comprehensively, lifting promotes the machinery and equipment of transporting, the fields such as king-post board frame that lifting moving changes.
