Description
Invention field
The utility model relates to a kind of improvement of scissors mechanism telescopic lifting type of drive.Especially the shearing fork telescopic lifting mechanism that drives by the drag-line tractive.
Background technology
In the prior art, with scissors mechanism as telescopic lifting be supported on produce and daily life in quite extensively general application is arranged, they all are to drive scissors mechanism by screw rod or pneumatic-hydraulic cylinder to realize the lift telescopic variation usually; Especially be that the scissors fork elevating machine that drives, platform, frame, ladder etc. have formed numerous series of products with the hydraulic actuating cylinder, various facilities or operation field such as be widely used in ascending a height, promote, transport.Resemble Chinese patent " a kind of autocontrol hydraulic lifting ladder " 95209483.5, " wall tunnel type hydraulic elevating platform " 03229183.8 etc., its innovation is to place position very to promote to change the scissors rod angle hydraulic actuating cylinder to drive shearing fork telescopic lifting support.Yet, though drive with hydraulic actuating cylinder and to cut fork row telescopic lifting power powerful flexible movements, but it must pressurize from oil pump, pipeline is carried, high pressure control is done work to oil cylinder, system complex, mechanism is various, parts are accurate, especially pressure duct and control system, in case faults such as generation leakage will seriously jeopardize safety, so it ensures that setting again must be especially thorough complete.Simultaneously, oil hydraulic cylinder also is difficult to the state that can remain unchanged for a long time under heavy load.In a word, the volume macrostructure is numerous, make difficult cost height, safeguard tired fault frequently, the safe differential limitation is many, is that Driven by Hydraulic Cylinder is cut the obvious deficiency that the lifting of fork mechanical-stretching is supported.
Summary of the invention
The purpose of this utility model is that a kind of new shearing fork telescopic lift drive mechanism or device will be provided, and it makes strength transmission by drag-line and pulley, and the tractive that stops with the folding and unfolding of control drag-line drives scissors rod variable angle realization telescopic lifting.
The purpose of this utility model is achieved in that tractive driven shearing fork telescopic lifting mechanism constitutes by cutting fork row, pulley, drag-line and tractive driver train etc.Wheels arrangements is in each crosslinked contact of scissors rod of cutting the fork row, drag-line links up serial between each pulley, the tractive driver train drives and the control drag-line tightens up, release or static tractive, changes or limits scissors rod variable angle state through drag-line and pulley transfer function strength and support to drive the flexible telescopic lifting of scissors mechanism.Tractive driven shearing fork telescopic lifting mechanism application pattern is numerous, operating power is powerful, in combined scissors fork mechanism telescopic lifting, can be listed as the driving of application tractive by wherein partly cutting to pitch row or all cut fork by mechanism; Can form the tractive driving by one group of drag-line and pulley or by two groups of drag-lines and pulley same cut in the fork row.Tractive driven shearing fork telescopic lifting mechanism rational in infrastructure stable, flexible steadily reliable, firm supporting is strong, of many uses various.Compare with the hydraulic-driven scissors mechanism, its mechanism's letter material is economized from heavy and light, is made the low effect height of easy cost.Can be widely used in mechanical equipments such as various scissors fork elevating machines, platform, frame, ladder, serve comprehensively building decoration engineering construction, lifting promote transport Work machine, lifting moving changes king-post board frame or the like field.
