Detailed description of the invention
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is elaborated.But protection domain of the present utility model is not limited to following embodiment, the simple equivalence namely in every case done with the utility model claim and description changes and modifies, and all still belongs within the utility model patent covering scope.
As shown in Figure 1, 2, a kind of vertical lifting mechanism, the lifting mechanism comprising chassis 1, article carrying platform 2 and be located at for driving this article carrying platform to carry out vertical lift between this chassis and article carrying platform.This lifting mechanism comprises the connecting element 3, at least one movable part 4 and the screw mandrel 5 that set gradually, and the bottom of connecting element 3 is fixed on chassis; The lower surface of each movable part is provided with sprocket wheel 6, and this sprocket wheel is engaged with chain 7 respectively; Near connecting element and the one end being positioned at the chain on the movable part of inner side is fixed on the upper end of connecting element 3, the other end of this chain is fixed on the bottom of movable part adjacent with it; The one end of chain on movable part between two movable parts is fixed on adjacent with this movable part and on the upper end of the movable part 3 of connecting element, and the other end of this chain is fixed on adjacent with this movable part and on bottom away from the movable part of connecting element; Away from connecting element and the one end being positioned at the chain on outermost movable part is fixed on the upper end of the movable part adjacent with this movable part, the other end of this chain is fixed on article carrying platform; Screw mandrel is vertically located on article carrying platform, and this screw mandrel can dally along its circumferencial direction by this article carrying platform relatively; Screw mandrel is outer has nut 8 by screw-threaded engagement, this nut again with away from connecting element and the movable part being positioned at inner side be connected; The upper end of screw mandrel is provided with the handwheel 9 for driving screw mandrel to rotate.
Preferably, described connecting element and the lug 10 upper end of movable part is respectively equipped with for being connected with chain; The side of described article carrying platform is interval with up and down two screw mandrel fixed parts 11, the two ends of described screw mandrel are inserted in two these screw mandrel fixed parts respectively also can dally by this screw mandrel fixed part relatively; Described nut is between two screw mandrel fixed parts
As a kind of better embodiment, described connecting element and movable part are column, and arrangement in parallel successively.Or described connecting element and movable part are sleeve, and interval is sheathed successively, namely form sleeve-type lifting mechanism.
The present embodiment, namely its connecting element of mode shown in accompanying drawing 1-2 and movable part all adopt column form, and movable part arranges two.During use, if need to promote article carrying platform, (or anticlockwise direction) handwheel 9 can be rotated along clockwise direction, handwheel drives screw mandrel 5 synchronous axial system, due to screw mandrel 5, relatively article carrying platform 2 is along the idle running of this screw mandrel 5 circumferencial direction, and screw mandrel 5 and article carrying platform 2 in the vertical direction keep synchronization lifting simultaneously, and nut 8 and screw mandrel 5 are connected with a joggle, therefore, the rotation of screw mandrel 5 then drives the relative screw mandrel 5 of nut 8 to move downward.When the relative screw mandrel 5 of nut moves downward, move downward near article carrying platform 2 i.e. outermost movable part 4 also relative screw mandrel 5, simultaneously due to the gravity of connecting element and movable part 4 self, this outermost movable part sprocket wheel bottom then rolls along its chain and makes another movable part 4 of this relative inner side that it closes on of movable part 4 increase, simultaneously, the another movable part of the inner side that another movable part 4 also closes on it relatively rises, the like, until movable part 4 opposed fixed member 3 of inner side rises, like this, successively its movable part 4 closed on or connecting element 3 have been lifted a segment distance to each movable part 4 relatively, namely article carrying platform 2 is finally made to be lifted certain height, thus achieve the lifting of this lifting mechanism.When this lifting mechanism needs to land, rotate handwheel 9 in opposite direction, now due to the gravity of movable part 4 self, each movable part 4 is progressively folded to the same height of connecting element 3, and article carrying platform 2 is also synchronously declined, thus realizes the landing of this lifting mechanism.
