Abstract
The invention provides lifting equipment, which has a self-locking function and low height. In particular, a compound band 2 forms the rising motion of a single liftable compound pipe through a combined motion of a compound mechanism 5 and forms the falling motion of the single liftable compound pipe through decomposed motion of the compound mechanism 5. The single liftable compound pipe can be kept at the stopped position for long time and has shallow foundation pit.
Description
Technical field
The present invention relates to a kind of mechanism of vertical lift, form class is like jack, and external loading vertically acts on the equipment upper end.
Background technology
The bay-lift of certain stroke has corresponding minimum clear height, just the shared height of equipment self.At present bay-lift has hydraulic-driven and screw mandrel to drive that mode realizes that merits and faults is respectively arranged in two usually: 1) identical stroke generally is the shared device height minimum of hydraulic pressure bridging formula bay-lift.Hydraulic pressure bridging formula bay-lift needs a plurality of hydraulic cylinder synchronous work, because a plurality of hydraulic actuating cylinders can only undertake softly can't realizing that rigidity is synchronous synchronously by synchronous valve, so precise synchronization realizes difficulty.When Lifting platform was parked in a certain position, there was diff-H in the diverse location of Lifting platform.Hydraulic pressure bridging formula bay-lift self does not possess self-locking performance, and when a certain stop position kept for a long time, there was leakage in hydraulic valve self and causes whole Lifting platform to have certain sedimentation.If there is fixed mesa to carry out reference, diff-H still clearly.2) bay-lift of screw mandrel driving has from trivial property, can eliminate the vice proper of hydraulic pressure bridging formula bay-lift, can keep for a long time.The multi-filament bar adopts the earth's axis as common rigid shaft, has guaranteed the precise synchronization of the multi-filament throw of lever, has eliminated the diff-H of diverse location.The shortcoming of screw mandrel bay-lift is that the big more required screw mandrel length of the stroke of bay-lift is also big more, and required foundation ditch is also dark more.
The present invention just provides and a kind ofly can take into account the lifting mechanism that the low characteristics of the shared height of hydraulic pressure bridging formula bay-lift equipment and screw mandrel bay-lift have the advantage of self-locking performance simultaneously.
Summary of the invention
Purpose of the present invention just provides a kind of have self-locking performance, the low lifting mechanism of self shared height.Can mainly move by " combination " or " decomposition " of composite structure by single lifting multiple unit tube, form the rising or the descending motion of multiple unit tube by composite band.
Can regard one " screw mandrel that can decompose " as by single lifting multiple unit tube, its motion principle equally has self-locking performance with the screw mandrel transmission.Different is screw mandrel is one section round steel pipe is by being machined to the part of certain screw thread form, self can not " decompose " or " combination " and can only carry out single-piece and rise or descending motion.Can single lifting multiple unit tube be to become to form " screw mandrel " by composite band " combination " to form vertical motion, multiple unit tube has self-locking performance; Can single lifting multiple unit tube " if decomposition " then become composite band then form descending motion, it be the low reason of the shared height of equipment that multiple unit tube self can " decompose ".Therefore can self-locking performance, low these two advantages of self shared height have been taken into account by single lifting multiple unit tube.
Wherein composite band is divided dextrorotation composite band and left-handed composite band, and composite structure also divides dextrorotation composite structure and left-handed composite structure, and can single lifting multiple unit tube also being divided into can single lifting dextrorotation multiple unit tube and can the left-handed multiple unit tube of single lifting.
Below describe the upward movement and the descending motion process of liftable multiple unit tube in detail:
A) can single lifting dextrorotation multiple unit tube 1) " combination " motion of upward movement dextrorotation composite band needs the upward movement by the clickwise formation liftable dextrorotation multiple unit tube of dextrorotation composite structure; 2) " decomposition " of descending motion dextrorotation composite band motion needs to form by the left-hand revolution of dextrorotation composite structure the descending motion of liftable dextrorotation multiple unit tube.
B) can the left-handed multiple unit tube 1 of single lifting) " combination " motion of the left-handed composite band of upward movement needs the upward movement by the left-handed multiple unit tube of left-hand revolution formation liftable of left-handed composite structure; 2) " decomposition " of the left-handed composite band of descending motion motion needs to form by the clickwise of left-handed composite structure the descending motion of the left-handed multiple unit tube of liftable.
System can produce additional torque in the motion process, and the built-in boots of leading that center fixed is installed are realized self-equalizing, only depend on single lifting multiple unit tube also can finish like this and rise or descending motion.
Can keep institute's stop position for a long time and have more shallow equipment foundation ditch by single lifting multiple unit tube, thereby reduce the excavation of foundation pit expense.It is a kind of product that well substitutes present conventional jacking equipment, but it is not suitable for carrying out lifting under the operating mode at certain inclination angle having.
