The linkage type connecting rod lifting mechanism is characterized by further comprising a transmission device and a retracting device. The contact supporting point of a linkage lifting and positioning mechanism and a device is changeable so as to reduce impact damage and avoid the point blocking phenomenon. The linkage type connecting rod lifting mechanism has the advantages of being low in space requirement, reliable in mechanism connection, easy to lift and drop, simple in machining, manufacturing and assembling of parts and the like.
Description
Technical field
The present invention relates to a kind of coordinated type connecting rod lifting mechanism, belong to the equipment field of mechanical technique.
Background technology
On special purpose vehicle during the loading or unloading special equipment, need to adopt lifting mechanism that some special equipment is carried out ascending, descending or rotary movement, existing single fixedly lifting mechanism is fixed with the fulcrum that equipment contacts, cannot change, in ascending, descending or upset special equipment process, sometimes attachment point or the strong point are produced bigger instantaneous impact, be easy to occur the stuck situation of impact failure and dead point.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of coordinated type connecting rod lifting mechanism, this interlock lifting can change with the fulcrum that equipment contacts with detent mechanism, thereby reduce impact failure and avoid the stuck phenomenon in dead point, have, mechanism lower to space requirement connect reliable, lifting and subdue easily, advantage such as part processing manufacturing assembling is simple.
The present invention is achieved by following technical solution.
A kind of coordinated type connecting rod lifting mechanism of the present invention, comprise horizontal lead screw, housing, horizontal lead screw passes housing and is installed in the knock hole of housing, its left end horizontal location nut locking, also comprise driving device and retractor device, described driving device comprises by being threaded on the horizontal lead screw and being installed in the horizontal ball nut of outside, be installed in lower floor's gear and the upper strata gear of normal engagement in the housing, bore tooth and bore tooth with the coaxial upper strata that is connected of described upper strata gear with the coaxial lower floor that is connected of gear of described lower floor, be installed in the described housing and by being threaded in the horizontal transmission gear on the described horizontal lead screw, upper transmission gear with the awl tooth engagement of described upper strata, described horizontal transmission gear and the awl tooth engagement of described lower floor, be connected last setscrew nut and top ball nut on the described retractor device, last setscrew nut is positioned at outside.
Described retractor device is with the flexible screw mandrel of going up of outer telescopic tube by an end and constitutes.
Described upper transmission gear and described top ball nut and retractor device are by being threaded.
Compared with prior art, the technique effect that the present invention reaches is: the horizontal lead screw of mechanism and last flexible screw mandrel can move simultaneously, satisfying the lifting fulcrum changes within the specific limits, satisfying the lifting strut simultaneously changes in bigger angular range, can change the point of action that fulcrum can change tipping arrangement this moment, namely change the arm of force of tipping arrangement, thereby actv. reduces impact failure; This mechanism can be less at radius of turn, reliably connect under the big situation of degreeof turn, lifting and subdue easy, effectively avoided the dead point stuck phenomenon.This mechanism lifting time is fast.The external force that this mechanism needs is little, and the moment of generation is big, and this interlock lifting can lodge rapidly again in equipping motion process with detent mechanism and do not influence the motion of equipment.

The specific embodiment
Below in conjunction with the drawings and specific embodiments technical scheme of the present invention is further described, but that claimed scope is not limited to is described.
A kind of coordinated type connecting rod lifting mechanism of the present invention, comprise horizontal lead screw 1, housing 9, horizontal lead screw 1 passes housing 9 and is installed in the knock hole of housing 9, its left end is locked with horizontal location nut 6, it is characterized in that: also comprise driving device and retractor device, described driving device comprises by being threaded on the horizontal lead screw 1 and being installed in the horizontal ball nut 2 of housing 9 outsides, be installed in lower floor's gear 3 and the upper strata gear 7 of normal engagement in the housing 9, bore teeth 4 and bore teeth 8 with the described upper strata gear 7 coaxial upper stratas that are connected with the gear 3 coaxial lower floors that are connected of described lower floor, be installed in the described housing 9 and by being threaded in the horizontal transmission gear 5 on the described horizontal lead screw 1, upper transmission gear 10 with awl tooth 8 engagements of described upper strata, described horizontal transmission gear 5 and awl tooth 4 engagements of described lower floor, be connected last setscrew nut 11 and top ball nut 12 on the described retractor device, last setscrew nut 11 is positioned at housing 9 outsides.
Described retractor device is with the flexible screw mandrel 14 of going up of outer telescopic tube 13 by an end and constitutes.
Described upper transmission gear 10 and described top ball nut 12 and retractor device are by being threaded.
The principle of work of this mechanism is: horizontal lead screw 1 externally rotating speed is controlled down, do the whole device in the horizontal ball nut 2 levels pullings housing 9 of straight line horizontal motion along horizontal lead screw 1, horizontal transmission gear 5 is done with speed with horizontal lead screw 1 and is rotated when horizontal lead screw 1 rotates.Lower floor's awl tooth 4 that horizontal transmission gear 5 drives engagement rotates, lower floor's awl tooth 4 drives lower floor's gear 3 coaxial rotation, the upper strata gear 7 that lower floor's gear 3 drives normal engagement rotates, upper strata gear 7 drives upper strata awl tooth 8 coaxial rotation, awl tooth 8 in upper strata passes to upper transmission gear 10 with rotating speed and moment like this, upper transmission gear 10 passes to top ball nut 12 with rotating speed and moment, this moment, top ball nut 12 was done straight-line motion along last flexible screw mandrel 14, under the effect of moment, promote outer telescopic tube 13, thereby produce the supporting point position that the moment that promotes is delivered to tipping arrangement, make its lifting or upset.
When horizontal location nut 6 locking, and horizontal ball nut 2 is when throwing off, and then 1 of horizontal lead screw transmitted moment of torsion and do not have the straight line horizontal pull this moment, and mechanism at this moment just becomes one and only last flexible screw mandrel 14 done the flexible mechanism in location; If this moment, setscrew nut 11 was gone up in locking again, then mechanism becomes the fixed angle telescoping mechanism.
The supporting use of the push-and-pull that the connecting rod mechanism that the present invention relates to is mainly used in equipping and latching device, adopt the coordinated type connecting rod mechanism to make equipment realize that the rotation at certain angle requires and under certain condition upset and lifting demand, when the equipment transportation, play the effect of lifting and location, lifting and lodging rapidly in the equipment motion process, and can not produce any influence to the motion of equipment, can also satisfy good servo-actuated control simultaneously.
