Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of manual type vertical lifting mechanism, adopting pure mechanical mechanism, avoid use hydraulic efficiency pressure system, not only environmental protection, and cost being low.
The present invention in order to the technical scheme solving its technical matters and adopt is: a kind of manual type vertical lifting mechanism, comprise chassis, article carrying platform and be located at the lifting mechanism for driving this article carrying platform to carry out vertical lift between this chassis and article carrying platform, described lifting mechanism comprises connecting element, at least one movable part and the flake down drum set gradually, and the bottom of described connecting element is fixed on described chassis; Described in each, the lower surface of movable part is provided with sprocket wheel, and this sprocket wheel is engaged with chain respectively; Near described 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 described connecting element, 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 of described 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 described connecting element; Away from described 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 described article carrying platform; Described flake down drum is located on described article carrying platform, one is also provided with for driving the handwheel of this flake down drum rotation along this flake down drum axis, this flake down drum is wound with trailing cable, be positioned on outermost movable part be also provided with roller away from described connecting element, this trailing cable is fixed on the bottom of this outermost movable part through after described roller.
As a further improvement on the present invention, described connecting element and the lug upper end of movable part is respectively equipped with for being connected with chain.
As a further improvement on the present invention, described connecting element and movable part are column, and arrangement in parallel successively.
As a further improvement on the present invention, described connecting element and movable part are sleeve, and interval is sheathed successively.
As a further improvement on the present invention, described flake down drum is arranged on described article carrying platform in the horizontal direction.
The invention has the beneficial effects as follows: this manual type vertical lifting mechanism is pure mechanical mechanism, not only simple for structure, low cost of manufacture; And avoid use hydraulic efficiency pressure system, not containing hydraulic oil, and do not need the driving of the external energy completely, both energy-conserving and environment-protective, the working environment that some is harsher to clean requirement can be adapted to again.

Detailed description of the invention
Below in conjunction with accompanying drawing, a preferred embodiment of the present invention is elaborated.But protection scope of the present invention is not limited to following embodiment, the simple equivalence namely in every case done with the present patent application the scope of the claims and description changes and modifies, and all still belongs within patent covering scope of the present invention.
As shown in Figure 1, a kind of manual type 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 flake down drum 5 that set gradually, and the bottom of connecting element is fixed on chassis; Described in each, the lower surface of movable part is provided with sprocket wheel 6, and this sprocket wheel is engaged with chain 7 respectively; Near described 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 described connecting element, 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 of described 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 described connecting element; Away from described 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 described article carrying platform; Described flake down drum is located on described article carrying platform, one is also provided with for driving the handwheel 9 of this flake down drum rotation along this flake down drum axis, this flake down drum is wound with trailing cable 51, be positioned on outermost movable part be also provided with roller 8 away from described connecting element, this trailing cable is fixed on the bottom of this outermost movable part through after described roller.
Preferably, described connecting element and the lug 10 upper end of movable part is respectively equipped with for being connected with chain.
Preferably, 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.
Preferably, described flake down drum is arranged on described article carrying platform in the horizontal direction.
Its connecting element of mode shown in accompanying drawing 1 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 flake down drum 5 synchronous axial system, when flake down drum rotates, due to the gravity of movable part 4 self, the upper trailing cable 51 be wound around of flake down drum is driven to be elongated gradually, simultaneously, chain 7 on each movable part 4 is also pulled gradually, and then make between article carrying platform 2 and outermost movable part 4, between the movable part 4 be connected and all there occurs OQ t between the movable part 4 of inner side and connecting element 3, finally achieve the enhanced feature on the relative chassis of article carrying platform.
When this lifting mechanism needs to land, rotate handwheel 9 in opposite direction, what be now applied to trailing cable due to handwheel makes every effort to overcome the gravity taking movable part self, outermost movable part is driven to rise, also be pulled with each movable part 4 while of secondary, finally make each movable part be progressively folded to the same height of connecting element 3, article carrying platform 2 also synchronously declines, thus realizes the landing of this lifting mechanism.
