Description

A kind of mono- liter link mechanism of RGV

Technical field

The utility model relates to RGV, and in particular to a kind of mono- liter link mechanism of RGV.

Background technique

Pallet material is placed on different shelf access adit or takes pallet away from pallet material from shelf access adit by fork truck Material, and RGV needs from different shelf deposits or takes out pallet material.RGV needs to go to pallet material bottom, by pallet Material lifts, and is then delivered to designated position and puts down.Steadily vertical up-or-down movement is needed when RGV lifting tray material.Existing skill The RGV of art is mono- to rise some possibility for carrying and existing and falling back of bearing a heavy burden of link mechanism, and some single liter link mechanisms are asynchronous.Number of patent application A kind of shuttle lifting body, including jacking decelerating motor, jacking transmission are disclosed for 201220425449.9 patent document Axis, a pair of of long connecting rod group and two pairs of jacking seats, jacking transmission shaft are equipped with runner, and jacking seat includes jacking lower seat, jacking guide pillar With the jacking seat of honour, jacks lower seat and the jacking seat of honour is equipped with short connecting rod mounting base and connects long connecting rod group, jack decelerating motor Driving jacking transmission shaft；It further include the connecting rod adjustment dress being made of external screw thread spherical plain bearing rod end and internal screw thread spherical plain bearing rod end It sets, external screw thread spherical plain bearing rod end and internal screw thread spherical plain bearing rod end are threadedly coupled；Link adjusting gear both ends, which are separately connected, to be turned Wheel and long connecting rod group；Embedded bearing is equipped in the inner hole that the jacking seat of honour is connect with jacking guide pillar；Axis is set in the pin hole of short connecting rod Set.But two pairs of jacking seat spacings, from farther out, long connecting rod group length is too long, link adjusting gear drives connection rod set dyskinesia, lifts It rises material tray to have some setbacks, long connecting rod is caused to be easily deformed.Long connecting rod amplitude of deformation is increasing, and the jacking seat of honour lifts material support Disk resistance is increasing, and shake is generated when pallet material lifts, and pallet material is subjected to displacement, it is possible to be will lead to pallet material and be fallen It falls.Lifting tray material is repeated for a long time, and long connecting rod deformation is increasing, eventually leads to that long connecting rod group is stuck, and RGV can not work Make.

Summary of the invention

To solve problems of the prior art, the utility model provides a kind of mono- liter link mechanism of RGV, lifting tray Material synchronism stability, long connecting rod intensity are high, it is not easy to deform, lifting movement is smooth without hindrance.

A kind of to achieve the above purpose, the technical solution of the present invention is: mono- liter link mechanism of RGV, including objective table And lifting body, objective table are connect with lifting body, lifting body includes jacking driving mechanism, link adjusting gear, long connecting rod Group, short connecting rod group and jacking seat, jacking driving mechanism are equipped with runner, and runner connects link adjusting gear, link adjusting gear Long connecting rod group is connected, long connecting rod group is connect with jacking seat by short connecting rod group, is respectively equipped with jacking seat at long connecting rod group both ends, pushes up Seat up and connect with objective table, two jacking seats between be equipped with guiding device, the guiding device include guide seats, setting be oriented to Guide post on pedestal and it is connected in the guiding seat of honour that raising board bottom is moved up and down with objective table, the long connecting rod group is two Long connecting rod disposed in parallel is provided with more than one connecting rod between two long connecting rods.
