Description
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.
In the prior art, scissors mechanism the most common the most habitual be to do 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.
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 stacked row configuration pulley of fork and drag-line combination.The tractive dynamic assembly is made up of power, connection and speed change, control or the like, 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 the acceleration and the micro-manipulation that shrink or descend.
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, the machinery and the parts of various telescopic liftings can be simplified and improve to the 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.
Below in conjunction with the accompanying drawing signal this patent design-calculated structural principle and typical exemplifying embodiment thereof are described further:
In the accompanying drawing: (1) is attached frame, and (2) for cutting fork, (3) are riser guide, and (4) are housing, and (5) are drag-line, and (6) are pulley, and (7) are the tractive dynamic assembly, and (8) are support.
The group structure that accompanying drawing 1, Fig. 2, Fig. 3 illustrate pull and draw drive-type additive frame combined scissor fork expanding and lifting mechanism middle pulley (6), drag-line (5) and tractive dynamic assembly (7) is connected and tractive driving telescopic lifting groundwork, exemplify one and cut the variation configuration that the stacked row of fork (2) dispose one or several pulley (6) drag-line (5) combination, diagram tractive dynamic assembly (7) can be installed on the mechanism of the inside and outside up and down optional position of pull and draw drive-type additive frame combined scissor fork expanding and lifting mechanism.Fig. 4 has pulley (6) drag-line (5) to realize acceleration and the micro-manipulation example that mechanism's contraction descends with tractive for ad hoc.Fig. 5 and Fig. 6 are equipped with the expanding and lifting mechanism illustration that four pulleys (6) drag-lines (5) combination drives V-type and housing (4) is housed; Fig. 7 cuts the stacked row of fork (2) to establish two pulleys (6) and drag-line (5) combination tractive and drive at U type expanding and lifting mechanism and use example; Fig. 8, Fig. 9 are that the pull and draw drive-type additive frame combined scissor fork expanding and lifting mechanism is made tractive driving example by partly or entirely cutting stacked row configuration pulley (6) of fork (2) and drag-line (5) combination; Other various additive frame combined scissor fork flex lifting gearing also all can be used the manner tractive and drive.Among last example five figure, drag-line (5) can be various chain cables; Cutting fork (2) bar is the tubulose section bar, is through in the tube chamber and can not shows so part pulley (6) and drag-line (5) are latent.Tractive dynamic assembly (7) is made up of power, connection and speed change, control or the like, can be installed on the optional position such as upper and lower, inside and outside of mechanism, it is provided with pulley (6) the turnover company's of passing through drag-line (5) by support (8), can satisfy the application and the control of various special demands comprehensively.Integrated attached frame type combined shear-fork streatching-lifting mechanism of pull and draw drive-type additive frame combined scissor fork expanding and lifting mechanism and drag-line tractive drive various advantages, in force according to practical application to various different demands such as the scale of construction, moulding, load, stroke and degree of precisions, more can change attached frame (1) structure form type shape, select the quantity of pulley (6) drag-line (5) configuration set to hold lotus, adjust position performance that tractive dynamic assembly (7) is provided with etc., in the hope of reaching the properest cooperation and the most perfect efficient.Its application and development is had boundless prospects.
