The object of the present invention is achieved like this: tractive drives midpoint-connected combined scissor retractable lifting mechanism by midpoint
Connected combined shear-fork telescopic lifting mechanism configuration drag-line and pulley and the combination of tractive drive assembly are constituted.Described midpoint combination type
Combined scissors fork expanding and lifting mechanism is coupled two top underframes by two or more scissor columns head and the tail two ends through fan pendulum connecting rod and forms combination,
Several midpoint joint group frames are connected in each scissor position layer or the scissors rod midpoint bearing pin of some same scissor positions layer of many scissor columns,
Frame connection limits the combined scissors fork expanding and lifting mechanism that many scissor column locus are constituted.Midpoint combination type combined scissors fork telescopic lifting
The scissor column of mechanism is to be intersected middle-ends through cutting that bearing pin series connection in midpoint becomes that two scissors rod angles can change flexibly by two scissors rods
Fork, several scissors are concatenated by bearing pin with scissors rod head and the tail stacking Volleyball Association and are constituted in column；Fan pendulum connecting rod is that two ends can join with bearing pin
Connect scissor column two ends and top underframe only makees the fan-shaped rigid connecting rod swinging change；Top underframe is that mechanism top or base are by two
Individual or plural straightway framework intersects connection or head and the tail become angle to connect and compose plane rigid frame, its straightway
Framework is provided with the axis hole connecting fan pendulum connecting rod；Midpoint joint group frame is to couple the scissors rod of same scissor position layer in the many scissor columns of combination
Midpoint bearing pin, frame connection limits the rigid frame of many scissor column telescopic lifting time space positions.Described drag-line and pulley are that setting is worn
Row common pulley between scissor column scissors rod and drag-line, drag-line one end is connected to tractive drive assembly；Described tractive drives total
Become power tractive or the mechanical work of release drag-line driving scissor column scissors rod variable angle and power, control combination；Tractive
Midpoint-connected combined scissor retractable lifting mechanism is driven to be navigated within midpoint combination type combined scissors fork stretched by drag-line and pulley setting
Between the scissor column of contracting elevating mechanism, tractive drive assembly tractive or release drag-line drive midpoint combination type combined scissors fork telescopic lifting
The scissor column change scissors rod angle of mechanism realizes combined scissors fork mechanism telescopic lifting and constitutes.It is eliminated and abolishes conventional sliding connection
Structure simplifies to be simple to manufacture and realizes cost more to save performance the most in hgher efficiency.
